Problems solved by technology

[0004] A balance device is installed between the spray boom and the main body of the sprayer. For example, the patent application number is 200620021828.6, and the name is "Automatic Balance Suspension Mechanism for Spray Boom Sprayer". Uniformity, but the posture and posture of the spray boom cannot be adjusted actively, and the response effect to the low-frequency excitation signal is not obvious. When the passive suspension boom sprayer is working on sloped roads, the boom suspension system cannot keep the spray boom level with the crop surface, which will reduce the spraying uniformity of the sprayer

Abstract

The invention discloses a lance boom capable of actively adjusting the pose, which relates to the field of plant protection machinery. The lance boom consists of a mechanical part and a control part. The mechanical part comprises a direct-current servomotor, a driving pulley, two auxiliary pulleys, a worm-gear reducer, a frame, a hydraulic lifting frame, a rope, a lifting hydraulic cylinder and a lance boom assembly. The control part comprises distance sensors and a controller. When a spraying machine operates, the direct-current servomotor is controlled by the control part to drive the lance boom, so that the pose of the lance boom is adjusted. The spraying machine structured with the lance boom can inhibit the vertical irregular motion of the lance boom, and can ensure that the lance boom can be adapted to the working environment of the slope, and the uniformity of spray deposition is increased.

Description

technical field [0001] The invention relates to the technical field of plant protection machinery, in particular to a spray boom that can actively adjust its posture. Background technique [0002] Nowadays, spraying with boom sprayer has become an important method of crop protection, but when the sprayer is working, the irregular movement of the boom in the vertical direction and the working environment of the slope road surface will greatly reduce the uniformity of spray distribution, thus This leads to a decline in the effect of pesticide application, and in order to ensure the normal growth of crops, the method of increasing the amount of pesticide application is often used to make up for this deficiency, which will not only cause pesticide waste, but also cause environmental pollution. Therefore, it is of great significance to develop a boom sprayer that can effectively restrain the irregular movement of the boom in the vertical direction and can adapt to slope road su...
