Embodiment Construction

[0052] In order to clarify the technical solution and working principle of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] like image 3 Shown is a profiled spray boom of a sprayer, which includes a support suspension connected with the body of the sprayer and side arms of the sprayer installed on the left and right sides of the support suspension.

[0054] like Figure 4 to Figure 14 As shown, the support suspension is provided with a lift drive mechanism, a roll drive mechanism, a yaw drive mechanism, a vibration damping mechanism, etc., and is specifically composed of components such as a first frame 301, a second frame 302, and a boom center frame.

[0055] The support suspension is fixed to the frame of the sprayer through the first frame 301 . The first frame 301 is located at the rear of the second frame 302 , and is composed of two vertical groove-shaped stra...

Abstract

A profiling spray boom of a sprayer and a control method thereof, the profiling spray boom of a sprayer includes a support suspension connected to the body of the spray machine and spray boom sidearms on both sides, the support suspension includes an active part and a The passive part, through the passive part of the suspension, isolates the spray boom from the high-frequency motion excitation from the vehicle body, and provides a relatively stable platform for the active control of the spray boom's movement attitude. The active part of the suspension can be combined with sensors, controllers, actuators, etc. Make the boom track low-frequency ground slope changes and adjust the overall attitude of the boom. The side arm of the spray boom can be designed to be composed of multi-section trusses, and the truss sections are connected by kinematic joints. Attitude adjustment can effectively prevent the spray boom from touching obstacles. The invention can make the spray rod sprayer adapt to various complex terrains such as undulating ground, slopes, valleys, etc., and broaden the applicable occasions of the spray rod sprayer.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a profiled spray boom of a sprayer and a control method thereof. Background technique [0002] In order to increase agricultural output, crops must be controlled against pests and weeds. Boom sprayer is one of the important equipment for spraying chemical pesticides, fertilizers and plant production regulators, and is widely used in fields, lawns, nurseries and orchards. The operation effect is highly related to the uniformity of the spray distribution pattern. The boom is a large flexible and weak damping structure. The main movements of the boom during operation are yaw, roll, and vibration, which significantly affect the spray distribution. [0003] The disadvantage of the existing boom is that it is difficult to adapt to complex field ground such as slope and undulation, especially for large boom sprayers, such as figure 1 As shown in the figure, when the spra...
