[0003] Reference Publication (Announcement) Number: CN218418131 discloses a biological pesticide spraying device for agricultural planting. When the pesticide in the storage box is lower than the value of the liquid level sensor, the alarm emits a signal to remind the staff to add pesticide to the storage box, realizing the timely addition of pesticide during the spraying process of most biological pesticide spraying devices for agricultural planting, avoiding the phenomenon of the empty box of the biological pesticide spraying device for agricultural planting, facilitating the staff to timely discover the exhaustion of pesticide, and making the biological pesticide spraying device for agricultural planting more convenient to use. However, during the actual use process, the above device only relies on the electric push rod to drive the nozzle to move up and down, and the target area of pesticide application is limited. It cannot well cover and spray tall crops or densely planted crops, and the nozzle is only located in front of the device for pesticide application, so it needs to be frequently moved and adjusted during use, reducing the work efficiency. In view of this, this application proposes an agricultural planting pesticide spraying device. Summary of the Utility Model

[0034] 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.

[0035] The present invention provides a technical solution: As Figure 1 shown in Figure 2 , an agricultural planting pesticide spraying device includes a base 1. A plurality of pulleys 11 for moving are symmetrically arranged at the bottom of the base 1. A handle 12 is fixedly installed on the upper surface of the base 1. During use, the applicator can push the whole device through the handle 12 for movement. A liquid storage tank 2 is arranged at the upper end of the base 1. A tank cover 22 is hinged to the top of the liquid storage tank 2, and a rubber strip for sealing is arranged between the tank cover 22 and the liquid storage tank 2. A sealing plug 23 is arranged on the tank cover 22. The pesticide can be directly added into the liquid storage tank 2 by opening the sealing plug 23. An observation groove 21 is opened on the side wall of the liquid storage tank 2, and a transparent plate is arranged in the observation groove 21. Further, during the pesticide application process, the applicator can observe the liquid height in the observation groove 21 through the transparent plate at the rear, so as to judge whether it is necessary to add pesticide into the liquid storage tank 2.

[0036] As Figure 3 shown in

[0037] shown in Figure 4As shown in the figure, two mounting plates 4 are symmetrically arranged on the upper surface of the base 1. The tops of the two mounting plates 4 are respectively fixedly connected with top plates 41, and the side walls of the two mounting plates 4 are respectively fixedly connected with guard plates 42. A double-shaft motor 5 is arranged between the two mounting plates 4, and the output shafts of the double-shaft motor 5 respectively penetrate through the corresponding mounting plates 4.

[0038] A transmission mechanism 8 is arranged between the guard plate 42 and the mounting plate 4. The transmission mechanism 8 includes a gear 81, a first rack 82 and a second rack 83. The first rack 82 and the second rack 83 are symmetrically arranged on both sides of the gear 81, and both the first rack 82 and the second rack 83 are meshed with the gear 81. Limiting rods 84 are respectively slidably connected to the first rack 82 and the second rack 83. The gear 81 is connected to the output shaft of the double-shaft motor 5 through a coupling. The tops of the first rack 82 and the second rack 83 are respectively connected to the bottoms of the corresponding connecting rods 74. Both limiting rods 84 are fixedly connected to the side walls of the mounting plate 4. It should be noted that after starting the double-shaft motor 5, the output shafts on both sides of the double-shaft motor 5 will drive the corresponding gears 81 to rotate synchronously, so that the mutually meshed first rack 82 and second rack 83 move relatively. Further, by setting the corresponding limiting rods 84, the first rack 82 and the second rack 83 can be guided to move vertically, ensuring that the gear 81 is always meshed with the first rack 82 and the second rack 83.

[0039] As Figure 2 shown in the figure, at this time the first rack 82 moves upward, driving the connecting rod 74 to move upward synchronously. The top of the connecting rod 74 rotates with the sleeve 72 under the connection of the pin shaft 73, and at the same time drives the sleeve 72 to slide on the conveying pipe 7, and finally drives the conveying pipe 7 to rotate around the shaft seat 6 to adjust the coverage area of the nozzle 71. When the first rack 82 moves to the uppermost end, the double-shaft motor 5 is reversed, and finally drives the corresponding nozzle 71 to swing downward to reciprocally adjust the spraying angle of the nozzle 71.

[0040] As Figure 5 shown in Figure 6 the figure, a plurality of through grooves 43 are oppositely arranged on the two mounting plates 4. A plurality of conveying pipes 7 are respectively arranged on the through grooves 43 through the shaft seats 6. The shaft seat 6 includes a connecting plate 61 and a clamping plate 62, and the connecting plate 61 and the clamping plate 62 are rotatably connected. The connecting plate 61 is fixedly connected to the inner wall of the through groove 43. The clamping plate 62 is sleeved on the conveying pipe 7. A nozzle 71 is installed on the conveying pipe 7. A sleeve 72 is slidably connected to the conveying pipe 7. The bottom of the sleeve 72 is connected to the connecting rod 74 through a pin shaft 73.
