Spray rod stabilizing and automatic-balancing device of self-propelled spray rod sprayer

Abstract

The invention discloses a spray rod stabilizing and automatic-balancing device of a self-propelled spray rod sprayer. Left and right transverse spray rods mounted on the sprayer are combined with a movable gear, pulleys, three hanging rod counterweights and a fixed pulley groove of a semicircular-arc-shaped structure to form a system with the transverse spray rods supportive of self-balancing; a movable combination which can rotate independently and can attract mutually is formed through a fulcrum center shaft and two groups of strong magnets mounted in a transverse spray rod fulcrum center shaft sleeve and opposite in polarity. When a frame body jolts under influence of uneven ground, the transverse spray rods start jolting under the influence and is pulled to an opposite direction due to counteracting force of the hanging rod counterweights and quickly enabled to tend to balance; due to mutual attraction of the magnets, unstable jolting of the transverse spray rods in the process of balance correcting is eliminated effectively, so that the transverse spray rods can be quickly stabilized and automatically balanced truly.

Description

technical field [0001] The invention relates to a horizontal bar balancing device, in particular to a self-balancing device for stabilizing a spray bar of a self-propelled spray bar sprayer. Background technique [0002] Due to reasons such as technology and cost control, most of the spray booms installed on the existing self-propelled spray boom sprayers are directly connected to the frame and assembled together, and there is no independent automatic balance device for the spray boom. Therefore, when the field level is not good, the frame will shake with the ups and downs of the land, and affected by this, the spray boom will also shake with the frame, which will easily make the spray boom tilt and shake and scratch the crops , and even damage the boom. Although some self-propelled boom sprayers are equipped with a boom automatic balancing system, their design technology often uses a combination of ultrasonic / infrared distance measurement, electronic sensors and hydraulic ...

Problems solved by technology

Therefore, when the field level is not good, the frame will shake with the ups and downs of the land, and affected by this, the spray boom will also shake with the frame, which will easily make the spray boom tilt and shake and scratch the crops , and even damage the boom

Although some self-propelled boom sprayers are equipped with a boom automatic balancing system, their design technology often uses a combination of ultrasonic / infrared distance measurement, electronic sensors and hydraulic balance regulators, which is not only complex in structure, but also very expensive , making many manufacturers and users discouraged
