DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-3 In this embodiment, a pest spraying device for corn planting includes a base 1. Four rollers 7 are fixed to the bottom of the base 1. The outer surfaces of the four rollers 7 are all covered with anti-skid sleeves. By setting the anti-skid sleeves, the device can be controlled more stably when moving, avoiding the difficulty of device operation due to excessive slippery ground, and ensuring the safety of movement. A storage box 9 located on the left side of the liquid storage tank 4 is fixed to the top of the base 1, a connecting column 10 is fixed to the left side of the base 1, and a working box 2 is fixed to the right side of the top of the base 1. The inner cavity of the working box 2 is fixed with a lifting mechanism 3 that penetrates to the outside of the working box 2. The lifting mechanism 3 can To adjust the height of pesticide spraying, a liquid storage tank 4 for storing pesticides is fixed on the top of the base 1, and a sealing cover 8 is movably connected to the top of the liquid storage tank 4. A sealing ring penetrated by a handle 502 is fixed to the left side wall of the inner cavity of the liquid storage tank 4. The sealing ring can not only prevent the liquid in the liquid storage tank 4 from leaking, but also has the function of reducing friction. A filter screen is fixed between the left and right side walls of the inner cavity of the liquid storage tank 4. The filter screen can prevent dust and large particles from falling into the liquid storage tank 4 when adding pesticides and liquids, thereby avoiding blockage during spraying. The right side wall of the inner cavity of the liquid storage tank 4 is rotatably connected to a stirring assembly 5 that penetrates to the outside of the liquid storage tank 4.

[0024] It should be noted that the stirring assembly 5 includes a rotating rod 501 rotatably connected to the right side wall of the inner cavity of the liquid storage tank 4. The rotating rod 501 is rotatably connected to the inner cavity of the liquid storage tank 4 through a ball bearing. The ball bearing has the advantages of long service life, small size and light weight, and can adapt to different rotation speeds. At the same time, it can also use its own special structure to reduce friction. A handle 502 is fixed to the left side of the rotating rod 501 and passes through the outside of the liquid storage tank 4. A number of stirring rods 503 are fixed to the outer surface of the rotating rod 501, and a conveying assembly 6 is fixed to the top of the base 1 and passes through the inner cavity of the liquid storage tank 4.

[0025] It can be understood that the conveying component 6 includes a water pump 601 fixed on the top of the base 1, and the water inlet of the water pump 601 is fixed with a water suction pipe that runs through the inner cavity of the liquid storage tank 4. A transmission box 602 is fixed on the top of the tooth plate 304. A water pipe 604 is connected between the transmission box 602 and the water pump 601. The water pipe 604 is a rubber hose. When the transmission box 602 is lifted for height adjustment, the water pipe 604 will not be pulled and cause the water pipe 604 to be detached from the transmission box 602, thereby preventing the device from being unable to spray pesticides normally. Two nozzles 603 are fixed on the right side of the transmission box 602.

[0026] In this embodiment, the stirring component 5 is used to fully mix the pesticide and water. After the lifting mechanism 3 drives the transmission box 602 and the nozzle 603 to adjust the spraying height, the pesticide is transported to the nozzle 603 through the water pump 601 for spraying, thereby achieving the purpose of adjustable spraying height and better spraying effect.

[0027] See also Figure 4 In order to achieve the purpose of adjustable spraying height, the lifting mechanism 3 in this embodiment includes a servo motor 301 fixed to the left wall of the inner cavity of the working box 2, and a mounting frame is fixed to the outer surface of the servo motor 301. The servo motor 301 is fixed to the inner cavity of the working box 2 through the mounting frame. The mounting frame supports and fixes the servo motor 301, reduces the wear and shaking generated when the servo motor 301 is running, and further reduces the mechanical noise, thereby achieving the effect of extending the service life. The output shaft of the servo motor 301 is fixed with a driving gear 302, and the inner bottom wall of the working box 2 is fixed with a limited The limiting column 303 and the tooth plate 304 are provided with a movable groove matched with the limiting column 303. The outer surface of the limiting column 303 is movably connected with the tooth plate 304 meshing with the driving gear 302. The transmission box 602 is provided with a mounting groove matched with the tooth plate 304. The left side of the tooth plate 304 is provided with a plurality of tooth grooves matched with the driving gear 302. The matched tooth grooves can not only improve the accuracy of meshing, but also have better durability and smaller errors, and can reduce the friction and wear during meshing, and can have a longer service life.

[0028] In this embodiment, the driving gear 302 is engaged with the tooth plate 304 to drive the tooth plate 304 to move up and down. When the tooth plate 304 moves, it drives the conveying component 6 to adjust the height, and then the corn is sprayed with pesticides, thereby achieving the purpose of adjustable spraying height and better spraying effect.

[0029] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0030] The working principle of the above embodiment is:

[0031] First, water and pesticide are poured into the liquid storage tank 4, and the handle 502 is used to drive the rotating rod 501 to rotate, and the stirring rod 503 is used to fully mix the pesticide and water, and then the servo motor 301 is started. The output shaft of the servo motor 301 rotates and drives the driving gear 302 to start rotating. At the same time, the driving gear 302 is engaged with the tooth plate 304. Since the tooth plate 304 is limited by the limit column 303, the tooth plate 304 can only move up and down. When the tooth plate 304 moves upward, the transmission box 602 will be lifted. After being lifted to a suitable height, the servo motor 301 is turned off, and the water pump 601 is started at the same time. The mixed pesticide is transported to the nozzle 603 through the water pump 601, and finally sprayed on the corn, thereby achieving the purpose of adjustable spraying height and better spraying effect.
