[0017] Specifically, it also includes a balance detection device and a control center. The balance detection device uses a gyroscope, which is installed on the spray boom body 1 to detect the horizontal state of the spray boom body 1, the angle with the ground, or the relative distance between different parts of the spray boom body 1 and the ground. It is referred to as a gyroscope, also known as an angular velocity sensor, which is an inertial detection device used to measure and control the angular motion of an object in a relative inertial space. The physical definition is that a gyroscope is an angular motion detection device that uses a momentum-sensitive shell of a high-speed rotating body in a relative inertial space around one or two axes orthogonal to the axis of rotation. When the object rotates, the direction of its rotation axis remains unchanged when it is not affected by external forces. Therefore, it can be used to measure angular displacement or angular velocity. When the gyroscope is working, it needs a force to make it rotate quickly, generally reaching hundreds of thousands of revolutions per minute, and can work for a long time. Then, a variety of methods are used to read the direction indicated by the axis, and the data signal is automatically transmitted to the control center; the control center is installed on the spray equipment, and the control center is electrically connected to the balance detection device and the drive motor 6. The control center includes a control panel, and the control center is pre-installed on the spray equipment. The control center is electrically connected to the balance detection device and the drive motor 6. The balance detection device transmits the angle between the spray boom body 1 and the ground to the control center. After calculation, the control center controls the drive motor to make a corresponding change in the number of revolutions, generates corresponding counterweights at different positions of the spray boom body 1, and then adjusts the balance of the spray boom body 1.

[0018] Specifically, a semi-annular groove 8 is provided on the mounting seat 3, a limiting rod 9 is provided in the semi-annular groove 8, the inner end of the limiting rod 9 is connected to the counterweight assembly 5, and the arrangement of the semi-annular groove and the limiting rod 9 prevents the counterweight assembly 5 from excessive rotation.

[0019] Specifically, the counterweight assembly 5 includes a rotating rod 5-1 and a counterweight ball 5-2. The rotating rod 5-1 is fixedly connected to the pin 4, and the counterweight ball 5-2 is fixedly arranged on the upper end of the rotating rod 5-1.

[0020] Specifically, the suspension 7 includes two suspension arms, the upper ends of the two suspension arms are crossed and the intersection is connected to the spray device.

[0021] Working principle: When the utility model is working, a plurality of counterweight assemblies 5 are arranged in the length direction of the spray rod body 1, and the rotation of the counterweight assembly 5 is controlled by the driving motor 6 to change the center of gravity. At the same time, the spray rod body 1 is suspended on the spray equipment at a single point by using the suspension 7, so that the spray rod body 1 will not tilt too much due to the bumps of the spray equipment, and has good self-balancing performance. In addition, the arrangement of the balance detection device, the counterweight assembly 5 and the control center can effectively detect and adjust the angle between the spray rod body 1 and the ground, which greatly improves the balance of the spray rod body 1.
