Description
Technical Field
The technology relates to the field of vehicle-mounted wide spray rod type sprayers, and provides a spray rod self-balancing device suitable for a vehicle-mounted wide spray rod type sprayer.
Background
The rapid development of agriculture brings great economic benefit. Meanwhile, the frequent and frequent diseases and insect pests limit the further improvement of the yield and quality of agricultural products. Nowadays, the plant diseases and insect pests control machines at home and abroad are various. Among them, the machine-carried spray rod type sprayer is widely applied to the large-scale agricultural production process with the outstanding advantage of large spray width and high control efficiency. A spray bar sprayer is a motorized sprayer with spray heads mounted on either a transverse spray bar or an upright spray bar. The spraying machine has high operation efficiency, good spraying quality and even spraying amount distribution, is suitable for spraying liquid preparations such as various pesticides, fertilizers, plant production regulators and the like on a large area, and is widely used for field crops, lawns, nursery gardens, wall vineyards and specific occasions (such as airports, road snow melting, road side weeding and the like). Today's spray bar sprayers are mainly divided into three categories: self-propelled, traction, suspension. The length of the spray rod is between 10 and 36 meters, and a single-pivot suspension and spring damping mode is adopted between the spray rod and the frame to ensure the balance effect. Meanwhile, in order to more accurately control the balance of the spray rod during operation, a sensor is generally arranged on the spray rod to sense the balance state of the spray rod in real time, the sensor feeds back a state signal to a control system, and then the control system controls a compensation mechanism (generally a hydraulic mechanism) to work, so that the position of the spray rod is adjusted to be kept horizontal.
It is easy to find through the research that the main reason of the left and right shaking of the spray boom is as follows: the current boom sprayer frame is mostly fixedly connected with the boom, and the shaking of the road condition vehicle body frame is unavoidable during operation, so that the boom is pulled to shake left and right together, and the operation efficiency is affected. Therefore, the key point of the relative balance of the spray boom is that the rigid involvement between the frame and the spray boom can be reduced, so that the frame and the spray boom can rotate freely. At present, the research on the self-balancing device of a longer spray boom is less in China, the self-balancing spray boom on the market has the defects of slow reaction and larger shaking generally, and the self-balancing spray boom is difficult to popularize on a large scale.
