Solvent filling stations

How it works:

Mobile solution and filling station for plant protection products and liquid fertilizers RZS-16

In intensive farming, it is impossible to achieve optimal results without the use of pesticides that protect crops from weeds, diseases, pests, and mineral fertilizers that shape the yield. Their effective use depends on the

• weather conditions (air temperature, soil moisture, precipitation);
• optimal processing time;
• the right drug for the active ingredient.

One of the most important factors in the effective action of a pesticide on the pest organism is a carefully prepared physical solution with full compliance with the standards and the process of complete dissolution of the drug in water. After all, an improperly prepared physical solution, without observing the proportions of dissolution of the active ingredient with water and their incomplete dissolution negates compliance with the first three points.

Kobzarenko Plant helped farmers with this by developing the RZS-16 filling station for the optimal preparation and transportation of plant protection products and mineral fertilizers.

TECHNICAL CHARACTERISTICS OF RZS-16(3)

The 16^m3 tank, 1900 mm in diameter, is divided into three parts by two blind partitions: two sections for the working fluid (7.5^m3 each); one section for clean water (1.2^m3), which will be used to wash the first and second working sections of the barrel.

The tank is cylindrical, made of stainless steel, wall thickness 4 mm. The frame is reinforced, made of black metal, painted with two-component polymer paint. ADR spring suspension (Italy), 130×2150 mm solid axles, both axles with brakes. Payload is 20 tons. Wheels 560/60 R 22.5 (permissible load 6300 kg at 30 km/h).

For ease of use, the drum is equipped with a ladder with a platform and a tilt adjustment. The Scharmuller trailer ring (Austria) is individually selected depending on the tractor. The braking system is also individually selected, whether single-circuit, dual-circuit or hydraulic.

The solution preparation system consists of:

• chemical mixer (100 liters);
• a counter for counting the amount of fluid pumped in and out;
• a hydraulically driven centrifugal pump or a Honda motor pump that provides refueling of the tank and sprayer;
• two roller pumps (one for each working section), which ensure the preparation of the working solution, agitation and flushing of the tank;
• a water intake valve for pumping in and out water.

For washing, two injection washers were used for each working tank separately. For agitation, 4 anti-foam hydraulic mixers were used.

The mobile solution and filling station for plant protection products and liquid fertilizers RZS-16 allows for agitation (mixing the working solution independently in both containers), washing the working tanks with clean water. A chemical mixer is used to take the solution from portable containers and rinse them, as well as to prepare a preliminary mother liquor.

PREPARATION OF THE SOLUTION – THE BASIS FOR THE EFFECTIVE ACTION OF THE DRUG

1. Fill in water from a pond or other source using the Honda motor pump or a hydraulic pump driven by the tractor’s hydraulic system. For better dissolution of the preparation in water, it is recommended to leave the water barrel in the sun for some time to heat the water. The preparation dissolves better in warm water.

2. Adjust the water injection with the dosing meter. It is used both for filling and pumping. When filling, we can pump in the required amount of water in liters, which makes it possible to prepare the ideal preparation with exact observance of the recommended proportions. When pumping out, we regulate the amount of the prepared preparation, which we fill into the sprayer.

3. Measure the acidity of the water pH and its hardness (amount of salts) using the EZODO device. Water is the basis for the dilution of any pesticide. But poor quality water can reduce the effectiveness of pesticide and agrochemical treatments and damage equipment. Unsatisfactory results of pesticide treatments and foliar applications can be directly related to poor water quality. It is better to use distilled water for the preparation of working solutions, but it is difficult to obtain the required amount of water in farm conditions (for example, 100-400 liters per 1 ha of grain per treatment).

Therefore, you have to use the water that is available nearby, from a river, lake or pond. But its quality varies considerably and can be quite hard and with different acidity. Even water from the same body of water has different hardness and pH throughout the year because it depends on the amount of natural precipitation. In spring or rainy summers, the hardness is lower because the water that falls as rain is practically distilled and it dilutes the hard water in the reservoir. Conversely, in hot, dry summers, the hardness in such a reservoir increases because the water evaporates, leaving high concentrations of salts. Therefore, for effective pesticide application, it is necessary to know the exact hardness and pH. The EZODO device can help with this, as it determines its hardness and pH in a minute.

4. We improve water quality by adding adjuvants and surfactants.

Some farms face a problem: the pesticide did not work as expected. What is the reason? In most cases, water is to blame, as many pesticides are sensitive to alkaline hydrolysis. Simply put, they break down at a water pH of more than 7. There are several water parameters that affect its chemical nature:

Dirt. Dirty water contains small particles of silt or clay. These soil particles can absorb or bind the active ingredients of chemicals and reduce their effectiveness. This is especially true for glyphosate, diquat.

For comparison, water is considered dirty if a 5 or 50 kopeck coin is not clearly visible at the bottom of a regular household bucket (10-12 liters).

Water hardness. Water is considered hard if it has a high percentage of calcium and magnesium salts. Soap does not dissolve well in hard water. Hard water can cause some chemicals (phosphorus) to precipitate out of the water. As a rule, sensitive chemicals often contain additives to help overcome this problem. Herbicides such as glyphosate, 2,4 D, 2M-4X, and clopyralid are known to be affected by hard water (> 400ppm CaCO3). Hard water can also affect the balance of the surfactant system and therefore properties such as wetting, emulsification and dispersion. Very hard water can reduce the efficiency used to treat dirty water.

pH level of water. Most natural waters have a pH value between 6.5 and 8. In highly alkaline waters (pH>8), many chemicals undergo an alkaline hydrolysis process. This process causes the breakdown of active ingredients, which can reduce the effectiveness of pesticides. This is one of the reasons why spraying mixtures should not be left out for even one night. Glyphosate and clopyralid are particularly sensitive to alkaline environments.

Soluble salts. Very salty water can cause difficulties in dissolving crystalline agrochemicals and clogging equipment, and is also more resistant to pH changes.

Organic substances. Water contains a lot of organic matter, such as plant debris, algae, and protozoa, which can block nozzles and filters. Algae can also react with some chemicals, reducing their effectiveness.

The addition of properly selected adjuvants and surfactants neutralize the acidity and hardness of water, thereby increasing the effectiveness of the product. The global market for agricultural adjuvants is led by such companies as AkzoNobel NV (Netherlands), Clariant International Ltd. (Switzerland), Solvay SA (Belgium), Dow Corning (USA), Croda Chemicals (India), Tanatex Chemicals BV (Europe) and Helena Chemical Company (USA). In addition to balancing water pH and hardness, adjuvants and surfactants: increase the adhesion and adhesion of pesticides and some fertilizers; enhance the effect of drugs in dry, hot weather; reduce application rates; increase resistance to rainfall washout; reduce foaming of tank mixtures, etc.

5. Observe the correct mixing of plant protection products and other preparations with each other. The manufacturer of each plant protection product, surfactant, or water-soluble fertilizer always indicates in the instructions the compatibility of these products with others. In addition, it is strictly necessary to observe the correct alternate mixing of the products with each other. Failure to observe the sequence can reduce the effectiveness of the preparation or even negate the entire treatment. When preparing tank mixtures, it is better to dissolve each component separately in a small amount of water, and then combine the solutions in the required sequence while continuously stirring the mixture.

We recommend the following sequence of adding plant protection products to the tank (through the mother liquor, not the concentrate) depending on their formulation. First, water-soluble sachets (WSS) are dissolved in the tank. They are the first to be dissolved because the polymer from which they are made must dissolve in water so that the contents of the bags can dissolve as well. Under normal conditions, this takes about two minutes in water at ambient temperature. Then water-soluble granules (WG) are added, followed by wetting powders (WP), water-dispersible granules (WDG), suspension concentrates (SC), emulsion concentrates (EC), water-soluble concentrates (WSC or WC), and aqueous solutions (AS). Fertilizers can be added after the surfactants and dispersants have completely dissolved.

6. In the presence of an agronomist on the territory of the current, slowly mix the plant protection products. The use of a mobile solution and filling station allows you to prepare a physical or mother liquor solution under the watchful eye of a specialist, which significantly reduces the risk of improper solution preparation and prevents theft, because stealing plant protection products in buckets is very inconvenient and very noticeable, because it is not a compact flask or sachet, but a whole container.

7. Rinse the crop protection agent canisters to maximize their utilization and prevent environmental contamination.When pouring pesticides from a canister, the universal mixer allows us to rinse the canister through the water nozzle equipped with the mixer, thereby using 100% of the product and preventing environmental pollution when disposing of canisters with pesticide residues. Only clean canisters are disposed of.

8. Select the required tank filling. The mixing tank allows you to automatically pump the product from a barrel via a PVC hose or to fill it from above. It has four working positions:

• filling with water from a barrel;
• mixing;
• downloading;
• washing canisters.

9. Dispose of the empty container. After refueling, the empty containers are placed in boxes and sent for recycling.

10. Rinse the mobile dissolving station with water after the work is completed. The tank is equipped with an autonomous shower with nozzles mounted inside the compartment. The rotating nozzle perfectly cleans the tank at high pressure and in limited space.

For better washing, flushing liquids can be added to ensure good rinsing of oil pesticides. Water is supplied to the shower system from a separate clean compartment with a volume of 1^m3, which is equipped with each mobile spraying station.

This mobile plant protection and liquid fertilizer station can be divided into 3 or 4 blind sections as required. The station allows you to prepare and transport two or more different solutions at the same time. Each section is equipped with its own pump and rinsing shower, which makes it impossible for them to mix or even come into contact with each other. This design of the barrel is convenient for those who plan to treat two or more crops with different preparations or one crop with different preparations that are not allowed to be mixed with each other.

ADVANTAGES OF USING THE RZS-16 MOBILE FILLING STATION:

1. Reducing the impact of the human factor: a) refueling at the plant protection products warehouse (once a day) prevents theft; b) when low-skilled workers are usually involved in auxiliary work during the application of plant protection products, this eliminates errors in the rate of the product, as the solution is prepared once a day under the supervision of a specialist;
2. Increased the area processed per shift by up to 70%. During a 6-hour shift, the sprayer makes three refuelings (1 hour of work, 1 hour of refueling). With a 5-minute refueling, the treated area increases by 70%.
3. Economic effect. Stirring the working solution for 60 minutes results in 100% utilization of the active ingredient. This eliminates the need for re-spraying by up to 30%, which entails logistics and additional labor costs.
4. Environmental effect. Empty containers for plant protection products are not spilled on forest belts and car bodies are not spilled during transportation.
5. The permissive effect. No need to obtain permits from the sanitary and epidemiological station, the environmental service and designers, as for stationary dissolvable units.
6. Ease of use. The ability to prepare complex solutions with the addition of adjuvants and full control over the pH of the medium and salt content.
7. Practicality. When refilling half-empty sprayers, there is no need to recalculate the % of plant protection products, which eliminates the error.
8. Savings on logistics. The right choice of nozzles, adjuvants, and good solution preparation can reduce the use of up to 100 liters per hectare.
