[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , the present invention provides a technical solution: a self-propelled soybean-corn combined planting boom sprayer, including a machine body 1, a support frame 16 fastened to the bottom of the machine body 1, and four sets of universal wheels arranged at the bottom of the support frame 16. Two sets of fixing plates 7 are fastened to the right side of the machine body 1, and a mounting plate 18 is fastened between the two sets of fixing plates 7. A connecting rod 5 is slidably connected inside the fixing plate 7. The tops of the two connecting rods 5 are fastened to the bottom of a cross plate 4. Two sets of mounting brackets 6 are fastened to the top of the cross plate 4. A plurality of spray nozzles 17 are arranged at the bottom of the mounting bracket 6, and the spray nozzles 17 are communicated with the inside of the machine body 1. A convex block 3 is fastened to the bottom of the cross plate 4. A mounting plate 18 is fastened between the two cross plates 4. A rotary motor 11 is fixedly arranged on the top of the mounting plate 18. The output end of the rotary motor 11 is key-connected with a threaded pipe 15. A sleeve 14 is screwed on the outside of the threaded pipe 15. A threaded hole is opened inside the sleeve 14, and the thread on the inner wall of the threaded hole is adapted to the thread on the outside of the threaded pipe 15. A central shaft 13 is fastened to the top of the sleeve 14. A pulley 12 is movably sleeved on the outside of the central shaft 13. The convex block 3 is a semi-elliptical convex block, and the thickness of the convex block 3 is greater than the thickness of the pulley 12. Through the cooperation between the pulley 12 and the convex block 3, when the pulley 12 moves forward, the spray nozzle 17 will be driven to rise by pushing the convex block 3, and when the pulley 12 moves back, the spray nozzle 17 will quickly descend, so that the height of the spray nozzle 17 can be quickly and conveniently changed, enabling the device to spray liquid medicine on plants of different heights, increasing the use range of the device, and bringing convenience to the work of operators, which is suitable for popularization.

[0020] Specifically, in order to prevent the connecting rod 5 from moving excessively, a buffer pad 10 is fastened to the outside of the connecting rod 5. The buffer pad 10 is a silica gel buffer pad, and the buffer pad 10 is located on the top of the cross plate 4. Thus, the displacement of the connecting rod 5 can be restricted by the buffer pad 10.

[0021] Specifically, in order to protect the rotary electric machine 11, a protective cover 2 is fastened to the top of the mounting plate 18, and the protective cover 2 is located outside the rotary electric machine 11 and the threaded pipe 15. Thus, by providing the protective cover 2, on the one hand, the protective cover 2 protects the rotary electric machine 11 and the threaded pipe 15, avoiding the situation where the bump 3 collides with the rotary electric machine 11 and the threaded pipe 15, ensuring the normal use of the rotary electric machine 11 and the threaded pipe 15. On the other hand, the protective cover 2 shields the rotary electric machine 11, preventing the rotary electric machine 11 from being damaged due to the dripping of the liquid medicine into the rotary electric machine 11, ensuring the normal use of the device.

[0022] Specifically, in order to enable the nozzle 17 to quickly move back, a support plate 9 is fastened to the outside of the connecting rod 5, a spring 8 is fastened to the top of the support plate 9, and the top end of the spring 8 is fastened to the bottom of the cross plate 4. Thus, by providing the spring 8, when the pulley 12 displaces and pushes the bump 3, the spring 8 will be squeezed by the support plate 9, and when the pulley 12 moves back and no longer pushes the bump 3, the spring 8 will drive the nozzle 17 to move back by bouncing the support plate 9, so that the nozzle 17 can quickly return to the initial position, ensuring the reuse of the device. Moreover, the cost of the spring 8 is low, increasing the scope of use of the device and being suitable for popularization.

[0023] All the electrical components appearing in this article are electrically connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.

[0024] During use, the rotary electric machine 11 is started so that its output end drives the threaded pipe 15 to rotate. The rotation of the threaded pipe 15 will drive the sleeve 14 to move leftward. The leftward movement of the sleeve 14 will drive the pulley 12 to move leftward by driving the central shaft 13. The movement of the pulley 12 will push the bump 3 upward. The upward movement of the bump 3 will drive the mounting frame 6 and the nozzle 17 to move upward by driving the cross plate 4. Thus, the spraying height of the nozzle 17 can be quickly and conveniently changed, enabling the device to be applied to the spraying work of plants at different heights.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
