[0025] Specifically, the height adjustment mechanism 8 for the movable wheels includes a fixing component 81, fixing holes 82, a lifting block 83, and a mounting base 86. The mounting base 86 is fixed to the lower side of the base plate 1. The lifting block 83 is slidably connected inside the mounting base 86. One end of the rotating shaft 10 is rotatably connected to the side of the lifting block 83 via a bearing. The fixing component 81 is provided inside the upper side of the lifting block 83. The mounting base 86 has multiple sets of fixing holes 82 corresponding to the fixing component 81 on its side.

[0026] By adopting the above technical solution, when adjusting the height of the movable wheel body 9, the limiting of the lifting block 83 by the fixing component 81 is released. At this time, the lifting block 83 can be slid outward from the inside of the mounting base 86, thereby realizing the height adjustment of the movable wheel body 9.

[0027] Specifically, the height adjustment mechanism 8 for the movable wheel also includes a spring 84 and a mounting hole 85. The mounting hole 85 is provided at the center of the upper end of the lifting block 83, and the spring 84 is installed inside the mounting hole 85. The upper end of the spring 84 is fixed to the top wall of the mounting base 86.

[0028] By adopting the above technical solution, when the lifting block 83 is raised or lowered, it will cause the spring 84 in the mounting hole 85 to be stretched, thereby assisting the lifting block 83 to be raised or lowered.

[0029] Specifically, the fixing component 81 includes a fixing pin 811, a limiting plate 812, a second spring 813, and a circular groove 814.

At this time, the lifting block 83 can slide out from the inside of the mounting base 86, thereby realizing the height adjustment of the movable wheel body 9. When the lifting block 83 rises and falls, it will drive the first spring 84 in the mounting hole 85 to stretch, thereby assisting the lifting block 83 to rise and fall. When the movable wheel body 9 moves, it will drive the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 will drive the first transmission wheel 13 to rotate. The rotation of the first transmission wheel 13 will drive the synchronous belt 7 to rotate. The rotation of the synchronous belt 7 will drive the second transmission wheel 6 to rotate. The rotation of the second transmission wheel 6 will drive the stirring shaft 11 to rotate. The rotation of the stirring shaft 11 will drive the stirring rod 12 to stir the spray liquid.

[0037] In this embodiment, when spraying crops, first loosen the fastening knob 272. After loosening the fastening knob 272, you can hold the handle 271. The handle 271 drives the rotating plate 274 to rotate. The rotation of the rotating plate 274 drives the pin 273 to rotate. The rotation of the pin 273 can adjust the angle of the mounting tube 22 and the spray head 23.

[0038] The structure and working principle of the film covering device 3, composed of a sliding rod, lead screw, moving block, crank handle, spring telescopic rod, pressure roller, and feeding roller, have been disclosed in Chinese Patent Application No. 202420995012.1, which discloses an integrated film covering and spraying device for flue-cured tobacco planting. Its working principle is as follows: when in use, the user moves the device to the location of the flue-cured tobacco planting, and then positions the moving wheel body 9 on both sides of the planting ridge. The user then pulls out one end of the film covering on the feeding roller, covering the top of the planting ridge and fixing that end. Next, the user lifts the spring telescopic rods on the two pressure rollers, causing them to retract and move the pressure rollers to the top of the film covering. Then, the user releases the spring telescopic rods, allowing the pressure rollers to press down on the top of the film covering and press the film into the soil of the planting ridge. Simultaneously, because the feeding roller is installed between the two spring telescopic rods, it also presses down on the top of the planting ridge.

[0039] The working principle and usage process of this utility model are as follows: When adjusting the height of the movable wheel body 9, press the fixing pin 811, causing it to slide out from the fixing hole 82 and compress the limiting plate 812 and the second spring 813, embedding them into the circular groove 814. At this time, the height of the movable wheel body 9 can be adjusted. The lifting block 83 can then slide outward from the mounting base 86, thereby achieving height adjustment of the movable wheel body 9. When the lifting block 83 rises or falls, it will stretch the first spring 84 in the mounting hole 85, thus assisting the lifting block 83 in rising and falling. When the movable wheel body 9 moves... When spraying crops, the rotating shaft 10 will rotate, which in turn will drive the transmission wheel 13 to rotate, which in turn will drive the synchronous belt 7 to rotate, which in turn will drive the transmission wheel 6 to rotate, which in turn will drive the stirring shaft 11 to rotate, which in turn will drive the stirring rod 12 to stir the spray liquid. When spraying crops, first loosen the fastening knob 272. After loosening the fastening knob 272, you can hold the handle 271. The handle 271 will drive the rotating plate 274 to rotate, which will drive the pin 273 to rotate, which will then drive the installation tube 22 and the spray head 23 to adjust their angles.
