Trailed sprayer OPSH-3521 Lvivagromashproekt, Lviv region.

Trailed sprayer OPSH -3521 provides high-quality chemical processing and effective use of preparations for the protection of field crops. Annovi Reverberi (Italy) membrane-piston pump with a capacity of 250 l/min is installed. Such productivity is sufficient for the technological process and high-quality mixing in the tank for uniform concentration of the drug in the working solution. The rotatingpump platform reduces the load on the drive shaft when turning the sprayer.
The working tank of our own production, with a volume of 3500 liters, is made of polyethylene with a thickness of 14 mm - perfectly smooth from the inside. This is a great advantage when cleaning it from the remains of the working fluid and mixing the working solution with the help of 2 hydraulic mixers installed inside. Due to the increased volume of the tank, the number of refueling is minimized to save time and fuel. The optimal shape ensures maximum use of liquid from the tank.
The sprayer is equipped with a hose for self-refueling and a flushing system for the main tank of 300 liters. It is worth noting that the spray system can be flushed even if the main tank is filled with the working solution. This reduces the possibility of system contamination when the sprayer has to be stopped in the field, for example due to bad weather.
The area on the chassis of the sprayer provides the basic requirements of safety equipment when servicing the tank neck.
Powder polymer painting of equipment provides reliable protection against corrosion.
At the beginning of work, granular, powder or liquid preparations are loaded into a mixer-mixer with a capacity of 35 liters made by Polmac (Italy). For convenience, it is lowered using a special folding bracket. The mixer thoroughly mixes any chemicals with water, without forming foam and splashing of the liquid, which protects the operator from its harmful effects. Next, the injector under pressure feeds the dissolved drugs into the main tank.
The clearance of the sprayer is 750 mm, which makes it possible to process almost all field crops at various stages of development without causing damage to them. The sprayer is equipped withwheels optimal radius 9.5 R 48 to reduce the load on the soil and increase the agrotechnical clearance.(//tractor-service.com)
Track width in OPSH -3521 is adjustable from 1.8 to 2.1 m.
The sprayer rod, 21 m long, consists of supporting metal sections. It is made in the form of a three-dimensional truss, which provides sufficient rigidity in the horizontal and vertical planes and makes it possible to use it under increased dynamic loads. The frame, the slider are made of a thick-walled square tube with a sliding system using polymer materials, the corrector cylinder ensures high-quality work on slopes. Double fixation of the boom sections in the working position guarantees their reliable operation (hydraulic and mechanical locks).
The bars are equipped with a hydraulic folding system and a tilt corrector. The two-hinged pendulum suspension provides excellent stabilization of the boom regardless of the terrain of the field, which is one of the key factors for the high-quality operation of the sprayer.
The quality of spraying field crops directly depends on the height of the boom, which can be adjusted from 50 to 210 cm without stopping the tractor.
Collectors of three-position nozzles are made of stainless steel.
Overlaps and gaps are a thing of the past. The navigation of the TeeJet Matrix Pro 570 GS reduces the consumption of fuel, chemicals or liquid mineral fertilizers, which increases the profitability and productivity of the sprayer.
Do you work at night? The "Night Light" option makes it easier to operate the sprayer at night, providing the ability to visually control the operation of each sprayer from the operator's seat during operation. LED lighting greatly facilitates the maintenance and transportation of the sprayer in case of insufficient lighting.
