Orchard sprayer with adjustable spray range

Abstract

The invention provides an orchard sprayer with the adjustable spray range. The orchard sprayer comprises a rack, an engine, a fan, a gearbox and a high-pressure pump; traveling wheels are arranged below the rack, and a spraying device is arranged on the rack and is constituted by a plurality of spraying heads which are fixed to an annular frame and radially distributed; a choke plate is arranged behind the spraying device, and the fan is arranged in front of the spraying device; the high-pressure pump and the gearbox are connected, and a clutch is arranged between the high-pressure pump and atransmission shaft for locking; the gearbox drives the traveling wheels; a water tank is arranged behind the chock plate and internally provided with a liquid conveying pipe to be connected to the high-pressure pump; and the high-pressure pump is connected with the spraying heads through outputting pipes. According to the orchard sprayer, the operation efficiency is high, a pesticide sprinkling machine can sprinkle a pesticide for crops with different heights, the heights of spraying droplets can be subjected to stepless adjusting, starting and using are carried out simultaneously, thus the connecting time is shortened, the field operation efficiency can be advantageously improved greatly, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to an agricultural implement, more specifically to an orchard sprayer with adjustable spray range. Background technique [0002] Orchard maintenance requires regular spraying of pesticides to fruit trees. Spraying devices generally include knapsack sprayers, high-pressure spray guns and air-supply spray vehicles. Wherein the knapsack sprayer and the high-pressure spray gun all have the problems of uneven spraying of the fruit medicine and high labor intensity. Existing spray trucks need to adjust the spraying distance when operating in different types of orchards, but there are problems: 1. The air supply spray truck is powered by a large wind force and a high-pressure pump, but in actual use when encountering fruit trees with different heights The driver needs to adjust the pressure of the high-pressure pump to meet the requirements of the operation, and at the same time control the speed of the vehicle to drive safely, which is...

AI Technical Summary

Problems solved by technology

Among them, both the knapsack sprayer and the high-pressure spray gun have the problems of uneven spraying of fruit medicine and high labor intensity.

Existing spray trucks need to adjust the spraying distance when operating in different types of orchards, but there are problems: 1. The air supply spray truck is powered by a large wind force and a high-pressure pump, but in actual use when encountering fruit trees with different heights The driver needs to adjust the pressure of the high-pressure pump to meet the requirements of the operation, and at the same time control the speed of the vehicle to drive safely, which is inconvenient to operate. Second, when large-scale operations in large orchards require fast driving operations, the pressure of the high-pressure pump is not adjusted synchronously with the driving speed , the droplets did not fall within the spraying range
