Modern crop production is unthinkable without treatment with liquid fertilizers, fungicides and other agricultural chemicals. Correct dosage application is safe for humans, but at the same time increases productivity, quality of fruits and grains.
Types of plant protection equipment
Crop protection equipment for applying liquid mixtures is basically divided into:
- field, row, band sprayers for land application (this group also includes application equipment attached to seeding or planting equipment);
- sprayers designed for the treatment of spatial crops, tapa trees and bushes.
P flat sprayers offered by https://sv-m.com/ru/catalog/po-naznacheniyu/zashchita-rasteniy/samokhodnye-opryskivateli/ associated with a traction vehicle (tractor) are divided into mounted and trailed. Self-propelled sprayers with their own chassis and engine are most in demand in farm field and horticultural farms.
Crop protection equipment is mainly used for surface spraying of field crops. The area and spatial application of protective substances as technological processes differ from each other. Firstly, by the method and form of the actual application, as well as by the volumes per unit area and the structure of the applied liquid.
How it works spraying equipment
Filtering elements provide filtration of mechanical impurities from the sprayed liquid, preventing clogging of the nozzles. The distribution of the applied liquid mainly consists of the suction and discharge pipes. The suction (vacuum in front of the pump) pipe leading from the main tank consists of a suction pipe with a drain pipe (tap or valve), a suction filter or, in some newer machines, a device for filling the injector with water from an external source. with suction basket and non-return valve.
The pressure connection serves to supply the sprayed liquid from the main tank to the end elements (nozzles) of the applicator. Includes main shut-off valve, working pressure regulator, pressure filter, safety valve, pressure gauge, section valves, connecting hoses to pipes on the application frame, nozzle holders (single or multiple) with anti-drip valves (shut off the liquid supply to the nozzles in the event of a pressure below the set value) and filters in front of the nozzles (sieves). Controls must be visible and accessible from the operating position and can be mechanically, electrically, pneumatically or hydraulically operated.
