Description

Technical Field

[0001] The utility model relates to the technical field of soybean planting, in particular to a pesticide spraying device for soybean planting. Background Art

[0002] When planting soybeans, it is inevitable to spray the soybean seedlings with pesticides. The current spraying methods include manual spraying with a pesticide tank, special spraying machines, and special drones. Manual spraying of pesticides has the problems of low efficiency and incomplete spraying, and spraying with a pesticide sprayer will crush the soybean seedlings and cause their death. Both have certain disadvantages. Drone spraying is not only efficient, but also will not come into contact with the soybean seedlings. The purpose of spraying pesticides can be achieved by spraying the pesticides through the spray nozzle below the drone. However, when the drone is high above the ground, the pesticides cannot be accurately dispersed on the surface of the soybean seedlings, resulting in a waste of pesticide resources. Once it flies low, the air generated by the drone during flight will cause the roots and stems of the soybean seedlings to bend or even break, which will also affect the normal growth of soybeans. Therefore, a pesticide spraying device for soybean planting is proposed to address the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a pesticide spraying device for soybean planting to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] As an optional solution of the soybean planting pesticide spraying device described in the utility model, wherein: a soybean planting pesticide spraying device comprises a bracket and a spraying drone;

[0006] The top of the bracket is fixedly connected to a spraying drone, and multiple sets of wings are installed on the outside of the spraying drone. The bottom of each wing is installed with a spraying mechanism. The outside of the spraying mechanism is connected to a medicine tube. The outside of the medicine tube is provided with a line-paying assembly, and the outside of the line-paying assembly is fixedly connected to the spraying drone. The other end of the medicine tube is connected to the medicine tank of the spraying drone.

[0007] The spraying mechanism includes a mounting frame, a motor and a threaded shaft. The outer side of the mounting frame is fixedly connected to the wing, the inner side of the mounting frame is fixedly connected to the motor, the main shaft end of the motor is fixedly connected to the threaded shaft, the outer side of the threaded shaft is spirally connected to a threaded sleeve, the bottom of the threaded sleeve is fixedly connected to a hollow tube, and the bottom of the hollow tube is fixedly connected to a nozzle, and the outer side of the hollow tube is connected to the medicine tube.

[0008] As an optional solution of the pesticide spraying device for soybean planting described in the utility model, the hollow tubes are arranged in multiple groups.

[0009] As an optional solution of the pesticide spraying device for soybean planting described in the utility model, slide grooves are opened on both sides of the threaded sleeve, and guide plates are provided inside the slide grooves, and the top of the guide plate is fixedly connected to the mounting frame.

[0010] When planting soybeans, it is inevitable to spray the soybean seedlings with pesticides. The current spraying methods include manual spraying with a medicine box, special spraying machines, and special drones. Manual spraying has the problems of low efficiency and incomplete spraying, and the spraying machine will crush the soybean seedlings and cause their death. Both have certain disadvantages. Drone spraying is not only efficient, but also does not come into contact with the soybean seedlings. The purpose of spraying can be achieved by spraying the medicine through the spray nozzle below the drone. However, the distance between the drone and the seedlings is too short. When the ground is high, the medicine cannot be accurately dispersed on the surface of the soybean seedlings, resulting in a waste of medicine resources. Once the drone flies low, the air generated by the drone during flight will cause the roots of the soybean seedlings to bend or even break, and will also affect the normal growth of soybeans. When in use, it can start the motor to drive the threaded shaft to rotate, thereby moving the threaded sleeve, and the threaded sleeve drives the hollow tube and nozzle downward. There is no need for the spraying drone to be too high or too low, ensuring that when the spraying drone is flying normally, the medicine sprayed from its nozzle can contact the soybean seedlings, and the air flow generated is not enough to cause serious damage to the soybean seedlings.

[0011] As an optional solution of the pesticide spraying device for soybean planting described in the utility model, the line-releasing assembly includes a guide cylinder, a limit plate and a spring, the outer side of the guide cylinder is fixedly connected to the spraying drone, and one side of the inner side of the guide cylinder is fixedly connected to the limit plate. A medicine tube is also provided inside the guide cylinder, and a spring is provided on the outer side of the medicine tube, and one side of the spring is fixedly connected to the limit plate, and the other end of the spring is fixedly connected to the sliding plate.

[0012] As an optional solution of the pesticide spraying device for soybean planting described in the utility model, the inner side of the sliding disk is fixedly connected to the medicine tube, and the outer side of the sliding disk is slidably connected to the inner wall of the guide cylinder.

[0013] When the hollow tube moves, it drives the medicine tube to move, and the medicine tube drives the sliding disk to move. The sliding disk squeezes the spring. At this time, the medicine tube can move smoothly to ensure the stable spraying of the medicine. After the hollow tube is reset, the sliding disk can be reset under the action of the spring, ensuring that the medicine tube is reset and tightened, ensuring the normal use of the equipment.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When the utility model is in use, the threaded shaft can be rotated by starting the motor, thereby moving the threaded sleeve, and the threaded sleeve drives the hollow tube and the nozzle to move downward, without the need for the spraying drone to be too high or too low, ensuring that the medicine sprayed from the nozzle can contact the soybean seedlings when the spraying drone is flying normally, and the air flow generated is not enough to cause serious damage to the soybean seedlings;

[0016] When the hollow tube moves, the hollow tube drives the medicine tube to move, and the medicine tube drives the sliding disk to move, and the sliding disk squeezes the spring. At this time, the medicine tube can move smoothly to ensure the stable spraying of the medicine. After the hollow tube is reset, the sliding disk can be reset under the action of the spring, ensuring that the medicine tube is reset and tightened, ensuring that the equipment can be used normally.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1 、 Figure 2 and Figure 3 , the utility model provides a technical solution:

[0024] A pesticide spraying device for soybean planting, comprising a bracket 1 and a pesticide spraying drone 2;

[0025] The top of the bracket 1 is fixedly connected to a spraying drone 2, and multiple sets of wings 3 are installed on the outside of the spraying drone 2. The bottom of each wing 3 is installed with a spraying mechanism 4. The outside of the spraying mechanism 4 is connected to a medicine tube 5. The outside of the medicine tube 5 is provided with a wire-releasing component 6, and the outside of the wire-releasing component 6 is fixedly connected to the spraying drone 2. The other end of the medicine tube 5 is connected to the medicine tank of the spraying drone 2.

[0026] The above-mentioned spraying mechanism 4 includes a mounting frame 401, a motor 402 and a threaded shaft 403. The outer side of the above-mentioned mounting frame 401 is fixedly connected to the wing 3, and the inside of the above-mentioned mounting frame 401 is fixedly connected to the motor 402. The main shaft end of the above-mentioned motor 402 is fixedly connected to the threaded shaft 403. The outer side of the above-mentioned threaded shaft 403 is spirally connected to a threaded sleeve 404. The bottom of the above-mentioned threaded sleeve 404 is fixedly connected to a hollow tube 406, and the bottom of the hollow tube 406 is fixedly connected to a nozzle 407. The outer side of the above-mentioned hollow tube 406 is connected to the medicine tube 5.

[0027] The hollow tubes 406 are arranged in multiple groups.

[0028] Slide grooves are provided on both sides of the threaded sleeve 404 , and guide plates 405 are provided inside the slide grooves. The tops of the guide plates 405 are fixedly connected to the installation frame 401 .

[0029] When planting soybeans, it is inevitable to spray the soybean seedlings with pesticides. The current spraying methods include manual spraying with a medicine box on the back, special sprayers, and special drones. Manual spraying has the problems of low efficiency and incomplete spraying, and the sprayer will crush the soybean seedlings and cause their death. Both have certain disadvantages. Drone spraying is not only efficient, but also does not come into contact with the soybean seedlings. The purpose of spraying can be achieved by spraying the medicine through the spray nozzle under the drone. However, when the drone is high above the ground, the medicine cannot reach the ground. The spraying drone 2 can accurately float on the surface of the soybean seedlings, resulting in a waste of medicine resources. Once it flies too low, the air generated by the drone during flight will cause the roots of the soybean seedlings to bend or even break, which will also affect the normal growth of the soybeans. When in use, it can start the motor 402 to drive the threaded shaft 403 to rotate, thereby moving the threaded sleeve 404, and the threaded sleeve 404 drives the hollow tube 406 and the nozzle 407 to move downward. There is no need for the spraying drone 2 to be too high or too low, ensuring that when the spraying drone 2 is flying normally, the medicine sprayed by its nozzle 407 can contact the soybean seedlings, and the air flow generated is not enough to cause serious damage to the soybean seedlings.

[0030] In the embodiment, three groups of nozzles 407 are installed at the bottom of each hollow tube 406, which can ensure the spraying area and the quality of the sprayed medicine, and the guide plate 405 provided can ensure cooperation with the sliding groove on the outside of the threaded sleeve 404, thereby playing a guiding purpose and ensuring that the threaded sleeve 404 moves up and down stably.

[0031] Example 2: This example is an improvement on Example 1. Figure 1 Specifically, the above-mentioned line-releasing assembly 6 includes a guide cylinder 601, a limit plate 602 and a spring 603. The outer side of the above-mentioned guide cylinder 601 is fixedly connected to the spraying drone 2, and one side of the inner side of the above-mentioned guide cylinder 601 is fixedly connected to the limit plate 602. A medicine tube 5 is also provided inside the above-mentioned guide cylinder 601, and a spring 603 is provided on the outer side of the above-mentioned medicine tube 5, and one side of the spring 603 is fixedly connected to the limit plate 602, and the other end of the above-mentioned spring 603 is fixedly connected to the sliding plate 604.

[0032] The inner side of the sliding plate 604 is fixedly connected to the medicine tube 5 , and the outer side of the sliding plate 604 is slidably connected to the inner wall of the guide tube 601 .

[0033] When the hollow tube 406 moves, the hollow tube 406 drives the medicine tube 5 to move, and the medicine tube 5 drives the sliding plate 604 to move. The sliding plate 604 squeezes the spring 603. At this time, the medicine tube 5 can move smoothly, ensuring the stable spraying of the medicine solution. After the hollow tube 406 is reset, the sliding plate 604 can be reset under the action of the spring 603, ensuring that the medicine tube 5 is reset and tightened, ensuring the normal use of the equipment.

[0034] In this embodiment, the limit plate 602 can prevent the sliding plate 604 from separating from the guide cylinder 601, ensuring that the device can be used normally. The medicine tube 5 is made of rubber material, which can be bent to ensure that the medicine tube 5 can be pulled to extend its length.
