[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figures 1 to 3 , the utility model provides a technical solution:

[0035] A pesticide spraying device for rice plant protection comprises a frame 1, wherein L-shaped brackets 12 are rotatably mounted at the front and rear corners on both sides of the left and right sides of the frame 1, a driving adjustment assembly 3 is arranged above the frame 1, and the driving adjustment assembly 3 comprises two rack rods 37 slidably mounted on both sides of the upper end of the frame 1, and the front and rear ends of the two rack rods 37 are rotatably connected to the adjacent L-shaped brackets 12 with a connecting driving rod 13, the upper end of the frame 1 is located inside the rack rod 37 and a gear 36 is rotatably mounted, the two gears 36 are meshed with the adjacent rack rods 37, the upper ends of the two gears 36 are fixedly mounted with groove wheels 35, and belts 351 are rotatably mounted on the circumferential surfaces of the two groove wheels 35.

[0036] Two longitudinal horizontal slide grooves 11 are provided near the edges on both sides of the upper end of the frame 1, and the two rack rods 37 are slidably installed in the adjacent slide grooves 11. The ends of the left and right L-shaped brackets 12 that are away from each other are rotatably connected with wheel hubs 121. A vertical slide groove rod 31 is fixedly installed on the outer side of the right rack rod 37 on the upper part of the frame 1, and an adjusting rod 32 is rotatably installed inside the slide groove rod 31. A slide table 321 is rotatably installed on the circumferential surface of the adjusting rod 32, and the slide table 321 is slidably installed inside the slide groove rod 31. A double-headed motor 33 is fixedly installed on the left side of the slide table 321 on the outer side of the slide groove rod 31, and a connecting head 34 is fixedly installed on the upper end of the groove wheel 35 on the right end.

[0037] By adopting the above technical solution, when in use, first, the user manually rotates the adjusting rod 32, and when the adjusting rod 32 rotates, it can drive the slide 321 to move up and down, and when the slide 321 moves downward, the lower end of the double-headed motor 33 will be plugged and combined with the connecting head 34, so that the connecting head 34 can rotate synchronously with the groove wheel 35 and the gear 36 on the right side, and when the gear 36 on the right side rotates, it can drive the rack rod 37 on the right side to slide back and forth inside the slide groove 11, so that the slide groove 11 can rotate with the connecting drive rods 13 at both ends, and the end of the connecting drive rod 13 away from the rack rod 37 will rotate with the L-shaped bracket 12, so that the L-shaped bracket 12 will rotate clockwise or counterclockwise with the wheel hubs 121 at both ends on the right side.

[0038] Secondly, the groove wheel 35 on the right will rotate with the belt 351, so that the belt 351 can rotate with the groove wheel 35 on the left. When the groove wheel 35 on the left rotates, it will drive the rack rod 37 on the left to slide synchronously, so that the two wheel hubs 121 on the left can rotate clockwise or counterclockwise as in the above case. It should be noted that when the two wheel hubs 121 on the left rotate counterclockwise, the two wheel hubs 121 on the right will rotate clockwise. On the contrary, the left wheel hub 121 rotates clockwise, and the two wheel hubs 121 on the right rotate counterclockwise, so that the frame 1 can perform a U-turn operation; with the cooperation of the above-mentioned multiple structures, the frame 1 can turn around with the material box 8 and the water pump 21 as a whole, thereby eliminating the tediousness of manual U-turn.

[0039] Specifically, Figure 4 As shown, a mounting base 2 is fixedly mounted on the upper left side of the frame 1, a water pump 21 is fixedly mounted on the upper end surface of the mounting base 2, and a water outlet nozzle is provided at the left end of the water pump 21.

[0040] A material box 8 is fixedly installed at the upper end of the frame 1 between the mounting seat 2 and the right rack rod 37. The left side of the material box 8 is fixedly connected to the right end pipeline of the water pump 21. A stirring rod 7 is rotatably installed at the inner center position of the material box 8.

[0041] A connecting column 5 is rotatably installed on the upper end surface of the material box 8, and a driving head 4 is rotatably installed on the right side surface of the material box 8 located at the upper end of the double-headed motor 33. A plurality of connecting rods 6 are respectively arranged between the two ends of the connecting column 5 and the upper end surfaces of the driving head 4 and the stirring rod 7. A mounting ring 81 is rotatably installed from the upper end surface of the material box 8 to the inside, and a plurality of holes are evenly opened from the upper end surface to the lower end surface of the mounting ring 81, and the plurality of connecting rods 6 between the connecting column 5 and the stirring rod 7 all pass through the mounting ring 81.

[0042] By adopting the above-mentioned technical solution, when in use, the adjusting rod 32 drives the slide 321 to slide upward, so that the upper end of the double-headed motor 33 can be plugged and combined with the driving head 4, and then the double-headed motor 33 can rotate with the driving head 4. At this time, the driving head 4 will move with the multiple connecting rods 6 at the upper end, and the upper left end of the connecting rod 6 will rotate synchronously with the connecting column 5. It should be noted that the upper end of the driving head 4 and the left and right ends of the connecting column 5 are provided with grooves for the sliding of the connecting rod 6, so that the multiple connecting rods 6 can slide along the grooves when rotating, thereby avoiding the situation where the connecting rod 6 cannot slide.

[0043] Secondly, the left end of the connecting column 5 will rotate with the multiple connecting rods 6 on the left side, and then the connecting rod 6 will rotate with the mounting ring 81, so that the lower end of the connecting rod 6 will rotate with the stirring rod 7, so that the stirring rod 7 can rotate inside the material box 8, so that the stirring rod 7 can keep the material inside the material box 8 in a rotating state at all times, thereby preventing the material inside the material box 8 from settling.

[0044] Working principle: First, the adjusting rod 32 moves the slide 321 downward, so that the double-headed motor 33 drives the connecting head 34 to rotate the groove wheel 35 and the gear 36 on the right side, thereby rotating the two wheel hubs 121 on the right side.

[0045] Secondly, driven by the belt 351, the gear 36 on the left can drive the rack rod 37 on the left to push the two wheel hubs 121 on the left to rotate, so as to realize the overall turning of the equipment.

[0046] Then, the double-headed motor 33 moves upward, so that the driving head 4 rotates with the multiple connecting rods 6 on the right side, so that the connecting column 5 can rotate with the multiple connecting rods 6 on the left side, and finally the connecting rod 6 on the left side can drive the stirring rod 7 inside the material box 8 to rotate.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
