Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] like figure 1 As shown, the present invention is a kind of air inlet automatic control type target sprayer, and the whole device is installed on the sprayer chassis 3 loaded on the tractor 1, including the left diversion bellows 7 and the right diversion bellows 14, all connected in the bellows To the nozzle 16 of the medicine box 17 and the centrifugal fan 8 whose wind direction is towards the nozzle 16, a hydraulic pump 4 is arranged on the pipeline between the medicine box 17 and the nozzle 16 to realize the pumping of the medicinal liquid. The spraying system adopts a traction structure, and is connected to the gearbox 5 through the transmission shaft 6, and the gearbox 5 is connected to the power output part of the tractor 1 through the universal coupling 2. The air inlets of the two bellows are all provided with a tapered air inlet device 12, th...

Abstract

The invention discloses a targeted spray machine with an automatically adjusted and controlled air inlet. The targeted spray machine comprises a left diversion air box, a right diversion air box, an ultrasonic sensor and a speed sensor, wherein the left diversion air box and the right diversion air box are fixedly arranged at the back end of a spray machine base plate; the spray machine base plate is loaded on a tractor; spray heads connected to a pesticide box, and centrifugal fans of which the wind directions face the spray heads are arranged in the air boxes; the air inlet of each air box is provided with a conical air inlet device; a circular baffle plate which is coaxial with each air inlet device, can rotate along a shaft and is provided with a plurality of fan-shaped holes is fixedly arranged on each air inlet device; each baffle plate is connected with a stepping motor; and a controller is used for outputting a control signal according to received tree crown information acquired by using the ultrasonic sensor and speed information acquired by using the speed sensor for controlling the stepping motors to rotate to realize control over the rotating angles of the baffle plates and realize change of the air amounts at the air inlets of the air boxes. The magnitude of the air amount at an air outlet can be changed by automatically adjusting the air inlet area of an air supply spray machine according to the detected size of a fruit tree crown and the operation speed of the tractor, so that accurate pesticide application to orchard gardens is realized, and the pesticide utilization ratio is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant protection machinery, and in particular relates to an air inlet automatic control type target sprayer. Background technique [0002] For a long time, chemical control has been the main method for the prevention and control of crop diseases, insect pests and weeds. However, at present, my country's pesticide application technology and pesticide application equipment are still at a relatively backward level, and the pesticide use rate is only 20%~30%, which is comparable to that of advanced pesticide application in developed countries. The technology is very different, so the implementation of precision pesticide application technology is an inevitable choice for the protection of the ecological environment and the harmonious development of man and nature. Orchard precision pesticide application technology can not only increase crop yield and reduce environmental pollution, but also improv...
