[0022] It should be noted that: similar signs represent similar items in the following drawings, therefore, once an item is defined in one drawing, it can not be further defined and explained in the subsequent drawings.

[0023] This embodiment mainly describes the structure of the spray device, and specifically as follows:

[0024] A kind of adjustable spray device for rice planting, as shown in Figure Figures 1-4 , including mobile car 1, spray box 2, spray head 201, conveying hose 7, booster 8, support 9, connecting pipeline 10, material bucket 16, sealing cover 17 and adjusting assembly, material bucket 16 and support 9 are installed on mobile car 1, spray box 2 is rotatably connected on support 9, a plurality of spray heads 201 are arranged at the front end of spray box 2, booster 8 is installed on mobile car 1, one end of connecting pipeline 10 is communicated with the bottom of material bucket 16, the other end is wrapped booster 8 and is connected with conveying hose 7, the other end of conveying hose 7 is communicated with the rear end of spray box 2, the top of material bucket 16 is provided with inlet, inlet is sealed by sealing cover 17 on the top of material bucket 16, adjusting assembly for adjusting the inclination angle of spray box 2 is arranged on support 9. After booster 8 is started, liquid medicine is pressurized and conveyed to spray box 2 through conveying hose 7, and finally sprayed out at high speed from spray head 201.

[0025] As shown in Figure 2 andFigure 3 As shown, the adjusting assembly includes a rotating frame 3, a torsion spring 4, an adjusting rail 5 and a fastening nut 6, the rotating frame 3 is rotationally connected to the support 9, the rotating frame 3 is fixedly connected to the left and right sides of the pesticide spraying box 2, the left side of the moving vehicle 1 is provided with a handle, the rotating frame 3 is provided with an extension rod facing the handle, the left side of the moving vehicle 1 is connected with an arc-shaped adjusting rail 5, the extension rod of the rotating frame 3 is slidingly connected in the adjusting rail 5, and the left end of the rotating frame 3 is threadedly connected with the fastening nut 6, and the fastening nut 6 is in extrusion fit with the adjusting rail 5. The extension rod of the rotating frame 3 slides along the arc-shaped adjusting rail 5, drives the pesticide spraying box 2 to rotate around the axis of the support 9, and at the same time the torsion spring 4 generates a reverse resistance under torsion to assist in stabilizing the angle. After the angle is fixed, the spraying box 2 is locked by tightening the nut, at this time the range of the spray head 201 is extended with the increase of the angle, which is suitable for narrow row spacing or wide row spacing field.

[0026] As shown in Figure 2 It also includes a gear set 11 and an agitating rod 12, the rotating shaft in the supercharger 8 passes through the right side of the connecting pipeline 10, the agitating rod 12 is rotationally connected in the material bucket 16, the agitating rod 12 is provided with helical blades, the rotating shaft of the agitating rod 12 passes through the right side of the material bucket 16, and the gear set 11 is connected between the agitating rod 12 and the rotating shaft of the supercharger 8. The blades on the agitating rod 12 agitate the pesticide liquid to prevent sedimentation and stratification. After the flowability of the pesticide liquid is improved, the concentration of the pesticide liquid sucked into the supercharger 8 through the connecting pipeline 10 remains uniform, avoiding the blockage of the spray head 201 caused by pesticide crystallization or flocculation, and ensuring the constant amount of pesticide sprayed per unit time.

[0027] As shown in Figure 2 It also includes a filter screen 13, the filter screen 13 is connected at the top inlet of the material bucket 16, and the filter screen 13 automatically intercepts solid particles in the pesticide liquid, such as undissolved pesticide blocks or field impurities, allowing only liquid pesticide to flow into the material bucket 16. This process avoids foreign matter entering the pipeline system, reduces the risk of spray head 201 blockage, and reduces the subsequent cleaning frequency.

Then, the tightening nut 6 is loosened, the rotating frame 3 is rotated and slid along the adjusting guide rail 5, and the rotating frame 3 is rotated on the support 9, thereby driving the pesticide spraying box 2 to select and twist the torsional spring 4. Then, the tightening nut 6 is tightened again to fix the inclination angle of the pesticide spraying box 2. Different spraying distances can be set by different inclination angles, and the scale 19 can prompt the distance to facilitate the user to adjust to the target angle. Finally, the booster 8 is started, the blades in the connecting pipeline 10 are rotated, the pesticide solution is pressurized and then enters the pesticide spraying box 2 through the conveying hose 7, and finally is sprayed out from the nozzle 201 to spray the rice. The mobile cart 1 is pushed to move for spraying. During the spraying process, the booster 8 drives the stirring rod 12 to rotate through the gear set 11 to continuously stir the pesticide solution in the material bucket 16, so as to ensure uniform spraying. The inclination angle of the pesticide spraying box 2 is adjusted in the middle, and the user only needs to reciprocate on the same road. After the spraying is completed, the booster 8 is turned off, and the residual pesticide solution on the nozzle 201 falls into the collection box 15. During the return process, it will not affect other plants or the road surface. When it is stationary for a long time, the protective cover 18 is covered to close the nozzle 201, so as to prevent the nozzle 201 from being blocked by mosquitoes or foreign matters.
