New technical solution for resource-saving tasks in chemical plant protection

Abstract

The problems in the production of row crops are considered. The technical solution in the field of chemical protection of plants, aimed at obtaining high quality products while reducing the cost of production, is offered. The retrofitting of serial boom sprayers with special divider bodies makes it possible to retain the function of continuous spraying with the possibility of chemical treatment in strips at the desired phase of growth and development of cultivated plants. It also describes the possibility of solving environmental problems in the agricultural industry by reducing the chemical load on the soil.

A Unit for Applying Liquid Fertilizers

“…The sprayer has additional support wheels 14 connected to the front hitch 9, on which a sealed tank 10 for working fluids is installed, a wind-protective casing is located between the drive wheels 3 and the front support wheels 14, an imbalance 15 is located on the rack 5 of the rear support wheel 4, while the rod 11 with sprayers 13 is telescopic and has compensation valves 16 for equalizing the pressure inside the rod inserted into the ends of the rod, a control panel 17 is located on the steering handle 8, communicated through pipelines with a working fluid tank. The design works as follows: during the movement of the sprayer for applying liquid concentrated fertilizers, after the operator presses the first key on the control panel 17, the compressor turns on, which creates pressure in the receiver 18 , and then in the tank with the working fluid 10, after pressing the second key, a valve opens, through which liquid concentrated fertilizers under pressure through a pipeline from a sealed tank 10, enter the composite rod 11, where then through the sprayers 12 they get to the plants, the imbalance 15 makes it possible to smoothly adjust the balance of the unit depending on the change in the level of the working fluid in the tank 10, the tank 10, in turn, has a relief valve for venting excess pressure in the system [8,9,10].…”
