Product Description
The purpose of this utility model is to provide a small-sized traction spray boom sprayer that is driven by a tractor that can be ridden, has good rigidity of the whole machine, is easy to use and maintain, has a balanced spray boom structure, and adopts a manual folding and lifting adjustment device, which can be used for spraying various crops in different growth periods.
The composition includes a frame, a handle assembly is installed on the upper part of the front end of the frame, a guide wheel is provided at the lower part, a power assembly is installed at the rear end of the frame, a gear box is installed at the rear, a gearbox is installed below the gearbox, a differential is installed at the power output end of the gearbox, a driving wheel is installed at the output end of the differential, a high-pressure pump is installed at the rear of the gearbox, and a pressure regulating valve is installed on one side of the high-pressure pump; the spray boom sprayer includes a medicine box rack, a medicine barrel is placed on the medicine box rack, the rear end of the medicine box rack is connected to the spray boom bracket, a spray boom is installed on the upper part of the spray boom bracket, and a number of nozzles are installed on the spray boom. Beneficial effects: reasonable structure, flexible operation, uniform distribution of spray volume, good spraying quality, greatly reducing manual labor intensity, and effectively improving labor productivity.
Working Principle
Working principle of traction boom sprayer: usually driven by the power output shaft of the tractor, the liquid in the liquid tank is delivered to the sprayer through the control valve and the infusion pipeline at a certain pressure. When the spray liquid pressure at the nozzle reaches the preset value, the anti-drip device automatically opens, and the liquid sprays out from the nozzle to form droplets and sprays to the target. The spray pressure is adjusted by the pressure regulating valve. The amount of spray can be adjusted by adjusting the spray pressure or replacing nozzles with different apertures. When the sprayer stops spraying at the end of the field or in the middle of the field, and the spray liquid pressure at the nozzle is less than the present value, the anti-drip device automatically closes, thereby playing an anti-drip role. The water in the liquid tank is generally added by the same liquid pump, but on some large traction boom sprayers, a centrifugal pump with a large flow rate is added to add water to the liquid tank. The height of the spray boom from the ground during operation is controlled by a mechanical or hydraulic adjustment mechanism. The horizontal balance of the spray boom is achieved by an automatic balancing mechanism. An elastic automatic return mechanism is provided between the spray bars at both ends and the middle section. During operation, when the spray bars at both ends pass over obstacles in the field, they can automatically return to their original positions.
Beneficial Effects
The beneficial effects of the utility model are: high operating efficiency, reasonable structure, flexible operation, uniform distribution of spray volume, good spraying quality, and greatly reduced labor intensity. It is widely used for weeding and disinfection of large-scale crops, lawns, nurseries, airports, roads, and highways. It can also be towed by trailers for short-distance transportation, effectively improving labor productivity.
