Description

Technical Field

[0001] This utility model relates to the field of pesticide spraying technology, and in particular to a pesticide spraying device for corn planting. Background Technology

[0002] A pesticide sprayer is an agricultural device that atomizes pesticide liquid and sprays it evenly onto crops. Common types include backpack sprayers, motorized sprayers, and drone sprayers.

[0003] In the use of motorized sprayers, pesticides are mainly stored in the tank, and then the machine is towed across the cornfield. The pesticides are then sprayed onto the corn through atomizing nozzles. However, during the movement of the motorized sprayer, the gap between the bottom of the machine and the ground is fixed, which causes the bottom of the machine to touch the corn plants, thereby damaging the corn and causing economic losses. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pesticide spraying device for corn planting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pesticide spraying device for corn planting includes a pesticide sprayer and an adjusting plate.

A limiting block located in the limiting groove is fixedly connected to its front side, and a second hydraulic cylinder located at the bottom end of the L-shaped plate is connected to its rear side through an L-shaped plate.

[0007] In addition, a preferred structure is that a support plate is fixedly connected to the middle of the bottom end of the pesticide sprayer via a first hydraulic cylinder.

[0008] Furthermore, a preferred structure is that wedge blocks located in wedge grooves are connected to the upper and lower ends of the adjustment plate.

[0009] In addition, a preferred structure is that the bottom end of the second hydraulic cylinder is rotatably connected to a traveling wheel via a rotating block.

[0010] In addition, a preferred structure is that a pesticide tank is fixedly installed on the upper left side of the top of the pesticide sprayer, and a nozzle is connected to the right side of the pesticide tank through a pipe and a pump.

[0011] Furthermore, in a preferred configuration, the gear shaft is driven by a drive motor.

[0012] The beneficial effects of this utility model are as follows: by setting an adjustment pipe and adjustment plate at the bottom of the pesticide sprayer, the bottom height of the machine can be adjusted when it moves in the cornfield, thereby avoiding contact with the corn and causing damage, and thus reducing economic losses.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 A pesticide spraying device for corn planting includes a pesticide sprayer 1 and an adjusting plate 2. Hollow adjusting pipes 11 are fixedly installed on the left and right sides of the bottom end of the pesticide sprayer 1. A gear shaft 12 is rotatably connected to the middle of the inner wall of the adjusting pipe 11. The gear shaft 12 is driven by a drive motor 28. The drive motor 28 is fixedly installed at the bottom end of the adjusting pipe 11, and partitions fixed to the inner wall of the adjusting pipe 11 are provided on the front and rear sides of the gear shaft 12.

[0017] The upper and lower ends and the left and right sides of the inner wall of the regulating pipe 11 are symmetrically connected to the regulating plate 2 through the wedge groove 13. The upper and lower ends of the regulating plate 2 are connected to the wedge block 22 located in the wedge groove 13. The left and right sides of the inner wall of the regulating pipe 11 are symmetrically provided with the limiting groove 14. The bottom end of the limiting groove 14 is in the same vertical plane position as the outer side of the partition.

[0018] Multiple racks 21 that mesh with the gear shaft 12 are fixedly installed on the inner middle of the adjusting plate 2. A limiting block 23 located in the limiting groove 14 is fixedly connected to its front side, and an L-shaped plate 24 is fixedly installed on its rear side. A rotating block 26 is fixedly connected to the bottom end of the L-shaped plate 24 through a second hydraulic cylinder 25. A traveling wheel 27 is rotatably connected to the outer side of the rotating block 26.

[0019] A pesticide tank 17 is fixedly installed on the upper left side of the top of the pesticide sprayer 1. A nozzle 18 is connected to the right side of the pesticide tank 17 through a pipe and a pump. A support plate 16 is fixedly connected to the middle of the bottom of the pesticide sprayer 1 through a first hydraulic cylinder 15.

[0020] In this embodiment, when spraying pesticides, water and pesticides are first put into the inside of the pesticide tank 17 through the feed port at the top of the tank 17. Then, the motor at the top of the tank 17 is started, and the motor drives the stirring paddle to fully mix the pesticides and water in the tank 17. Then, the pesticide sprayer 1 is transported to the cornfield where the pesticides need to be sprayed. This avoids the need for manual mixing of pesticides and water, thereby improving work efficiency.

[0021] When the pesticide sprayer 1 is transported to the cornfield, the second hydraulic cylinder 25 at the top of the rotating block 26 is then activated. The second hydraulic cylinder 25 drives the entire pesticide sprayer 1 to move upward, so that the bottom of the pesticide sprayer 1 is higher than the height of the corn in the cornfield. In this way, the bottom of the pesticide sprayer 1 will not touch the corn when it is moving.

[0022] Once the height of the pesticide sprayer 1 is adjusted, the first hydraulic cylinder 15 is activated, causing the support plate 16 to move downwards. Once the bottom of the support plate 16 contacts the ground, the pesticide sprayer 1 is moved upwards a certain distance, and then the first hydraulic cylinder 15 is stopped.

[0023] Then, the drive motor 28 is started. The drive motor 28 drives the gear shaft 12 to rotate in the adjusting tube 11. Then, through the rack 21, it drives the adjusting plates 2 on the left and right sides to move outward. This causes the L-shaped plate 24, the second hydraulic cylinder 25, the rotating block 26, and the traveling wheels 27 to move outward synchronously, so that the distance between the front and rear traveling wheels 27 matches the distance between the cornfields. Then, the drive motor 28 is turned off. In this way, the distance between the two traveling wheels 27 matches the spacing between the corn plants, so that the traveling wheels 27 will not crush the corn when moving.

[0024] At this point, the first hydraulic cylinder 15 is activated again, which drives the support plate 16 to reset. Then the pump can be started to transport the pesticide in the medicine tank 17 to the nozzle 18 through the pipeline. The pesticide is then atomized and sprayed onto the corn through the nozzle 18. Then the pesticide sprayer 1 is pushed, and the traveling wheels 27 on the pesticide sprayer 1 will rotate outside the rotating block 26, driving the pesticide sprayer 1 to travel in the cornfield and complete the spraying of all the corn.

[0025] By using the wedge block 22 and the wedge groove 13, when the adjusting plate 2 slides on the gear shaft 12 inside the adjusting tube 11, the wedge block 22 will not be displaced due to external factors, thus preventing interference during the sliding process. In addition, the inner side of the limiting block 23 will contact the bottom end of the limiting groove 14 and the outer side of the partition during rotation, thereby preventing the adjusting plate 2 from separating from the adjusting tube 11 when adjusting the distance between the walking wheels 27. Furthermore, the pesticide sprayer 1 is equipped with a battery, so the pesticide sprayer 1 will not be unable to work due to power failure during operation.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
