[0030] The above-mentioned drug discharge mechanism 3 includes a water pump, a diversion box and several water pipes. When the water pump is turned on, the pesticide inside the mixing box is discharged into the diversion box through two water pipes, and then the pesticide inside the diversion box is evenly discharged into the two spraying boxes 25 through the two water pipes.

[0031] See Figure 1 and Figure 2 In this embodiment, the lifting assembly 2 includes a threaded rod 21, the top and bottom outer surfaces of the threaded rod 21 are rotatably connected to the inner wall of the fixed column 13, the outer surface of the threaded rod 21 is threadedly connected to a moving block 22, and the bottom of the threaded rod 21 is fixedly connected to a bevel gear 24.

[0032] Furthermore, a motor 241 is fixedly connected to the top of the vehicle body 1, a rotating shaft 242 is fixedly connected to the output end of the motor 241, a bevel gear 243 is fixedly connected to the end of the rotating shaft 242 away from the motor 241, and the top of the side of the bevel gear 243 away from the motor 241 is meshed with the bottom of the bevel gear 24.

[0033] During the implementation process, according to the height of the fruit trees where pesticides need to be sprayed, the motor 1 241 is turned on to drive the rotating shaft 1 242 to rotate. When the rotating shaft 1 242 rotates, it will drive the bevel gear 2 243 to rotate. When the bevel gear 243 rotates, it will drive the threaded rod 21 to rotate through the bevel gear 1 24. When the threaded rod 21 rotates, it will drive the moving block 22 to move upward.

[0034] See Figure 4-5 The front and back sides of the moving block 22 are fixedly connected to a connecting frame 23. The two connecting frames 23 are symmetrically arranged with the center of the vehicle body 1. The outer surface of the connecting frame 23 is slidably connected to a limiting column 231. The bottom of the limiting column 231 is fixedly connected to the top of the vehicle body 1. The bottom of the connecting frame 23 away from the center of the vehicle body 1 is fixedly connected to an electric push rod 232. A sliding groove is provided inside the connecting frame 23.

[0035] A slider 234 is slidably connected to the inner wall of the slide groove, and a telescopic rod 233 is fixedly connected to the output end of the electric push rod 232.

The side of the medicine spraying box 25 close to the center of the vehicle body 1 is rotatably connected to a connecting block 251. The end of the connecting block 251 close to the center of the vehicle body 1 is fixedly connected to the end of the limiting column 231 away from the center of the vehicle body 1.

[0036] When in use, the moving block 22 moves and the two connecting frames 23 move upward. The electric push rod 232 is opened to drive the telescopic rod 233 to extend upward.

When the slider 234 moves upward, the spray box 25 is opened through the rotating rod 235, and the liquid medicine in the mixing box 12 is discharged into the spray box 25 through the medicine discharging mechanism 3 to spray pesticides on the fruit trees. The operator can not only easily adjust the height of the nozzle according to the actual height of the fruit trees and the operation requirements, without the need for other tools or complicated operations to improve work efficiency, but also ensure that the pesticide is sprayed in place at one time by accurately adjusting the nozzle height, avoiding the situation where some areas are missed or need for repeated spraying due to inappropriate nozzle height.

[0037] Example 2

[0038] This embodiment is equipped with a stirring component based on the first embodiment. Figure 1 and Figure 6 In this embodiment, the stirring assembly 4 includes a rotating shaft 2 41, the top outer surface of the rotating shaft 2 41 is rotatably connected to the inner wall of the stirring box 12, the top of the stirring box 12 is fixedly connected to a motor 2 42, the output end of the motor 2 42 is fixedly connected to the top of the rotating shaft 2 41, and the outer surface of the rotating shaft 2 41 is fixedly connected to a plurality of rotating frames 43.

[0039] A plurality of rotating frames 43 are arranged in a circular array with the second rotating shaft 41 as the center. The inner wall of the rotating frame 43 is rotatably connected to a rotating shaft 44 , and the outer surface of the rotating shaft 44 is fixedly connected to three rotating plates 45 .

[0040] Furthermore, a circular gear bar 47 is fixedly connected to the inner wall of the mixing box 12, and a gear 46 is meshedly connected to the top of the circular gear bar 47. The end of the gear 46 close to the second rotating shaft 41 is fixedly connected to the end of the rotating shaft 44 away from the second rotating shaft 41.

[0041] When in use, turn on motor 2 42 to drive rotating shaft 2 41 to rotate. When rotating shaft 2 41 rotates, it will drive several rotating frames 43 to rotate. When rotating frame 43 rotates, it will drive gear 46 to rotate on the top of circular gear bar 47. During the rotation of gear 46, it will drive rotating shaft 44 to rotate. When rotating shaft 44 rotates, it will drive several rotating plates 45 to rotate, so that the medicine at the bottom of mixing box 12 can be flipped upward, which not only makes the high-concentration pesticide at the bottom and the relatively low-concentration liquid on the upper layer fully mixed, avoiding the situation where the local pesticide concentration is too high or too low, but also the concentration of the sprayed liquid is uniform and stable, which can improve the effect of pest control and disease prevention, and avoid the problem of pesticide damage to crops or poor control effect due to uneven concentration.

[0042] Example 3

[0043] The only difference between this embodiment and the first or second embodiment is that Figure 6 In this embodiment, a plurality of heating tubes are fixedly connected between the inner surface and the outer surface of the mixing box 12.

[0044] Specifically, the mixing box 12 is divided into two layers, an inner layer and an outer layer, with an interlayer in the middle. The inner and outer layers are welded together, and the heating pipe is installed inside the interlayer.

[0045] In addition, the inner layer has a higher thermal conductivity than the outer layer, and the space between the heating tube and the outer layer is filled with thermal insulation material. The heating tube and the inner layer are in direct contact, transferring heat to the inner cavity of the mixing box 12 .

[0046] A mobile power supply and a circuit breaker are provided on the top of the vehicle body 1. The mobile power supply, the circuit breaker and the heating tube are connected by cables, so that the mobile power supply supplies power to the heating tube under the control of the circuit breaker. The specific electrical connection method and control method are conventional designs in the prior art and will not be elaborated in detail in this solution.

[0047] When the device is in use, the heating tube is connected to the mobile power supply through the circuit breaker. When the heating tube is connected to the mobile power supply, current passes through the heating element (resistance wire). According to Joule's law, heat is generated when current passes through the resistor. The resistance of the heating element is large, and it will heat up rapidly when current passes through, generating heat energy to heat the inside of the mixing box 12, so that the microbial pesticides inside the mixing box 12 remain active.

[0048] The working principle of the present invention is as follows: when it is necessary to spray pesticides on crops, first, microbial drugs and water are added into the mixing box 12 through the water inlet hole opened at the top of the mixing box 12, and the motor 242 is turned on to drive the rotating shaft 241 to rotate. When the rotating shaft 241 rotates, it will drive several rotating racks 43 to rotate. When the rotating rack 43 rotates, it will drive the gear 46 to rotate on the top of the circular gear bar 47. During the rotation of the gear 46, the rotating shaft 44 will rotate. When the rotating shaft 44 rotates, it will drive several rotating plates 45 to rotate, so that the medicine at the bottom of the mixing box 12 can be flipped upward, which not only makes the high-concentration pesticide at the bottom and the relatively low-concentration liquid at the upper layer fully mixed, avoiding the situation where the local pesticide concentration is too high or too low, but also makes the concentration of the sprayed liquid uniform and stable, which can improve the effect of pest control and disease prevention, and avoid the problem of pesticide damage to crops or poor control effect caused by uneven concentration. When it is necessary to spray pesticides on fruit trees, according to the height of the fruit trees where the pesticides need to be sprayed, the motor 1241 is turned on to drive the rotating shaft 1 When the slider 234 moves upward, the spray box 25 is opened through the rotating rod 235, and the liquid medicine in the mixing box 12 is discharged into the spray box 25 through the medicine discharging mechanism 3 to spray the fruit trees with pesticides. The operator can not only easily adjust the height of the spray nozzle according to the actual height of the fruit trees and the operation requirements, but also improve the work efficiency without the help of other tools or complicated operations. Moreover, by accurately adjusting the height of the spray nozzle, it can ensure that the pesticide is sprayed in place at one time, avoiding the situation where some areas are missed or need to be sprayed repeatedly due to inappropriate spray nozzle height.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
