Description

Technical Field

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

[0002] One of the most troublesome tasks in agricultural cultivation is pest control. The spraying of pesticides is particularly crucial in agricultural cultivation. Ordinary agricultural pesticide spraying devices are carried on the user's back, increasing the user's workload. For example, if the crops in agricultural cultivation grow unevenly, the requirements for pesticide spraying will be even higher.

[0003] Ordinary agricultural pesticide spraying devices are carried on the user's back, increasing the user's workload. Commonly used pesticide spraying devices are mostly mixtures of several pesticides, but there are problems such as uneven mixing of pesticides and residues remaining on the inner wall when less than half is used. When spraying different types of plants, the spraying angle of pesticides is relatively fixed, resulting in poor efficiency. Therefore, an agricultural pesticide spraying device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pesticide spraying device for agricultural planting, which aims to improve the problems of pesticide mixing, residue on the inner wall, and relatively fixed spraying angle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an agricultural pesticide spraying device, comprising a trolley, a base fixedly connected to the top of the trolley, a first motor fixedly connected to the top of the base, a rotating shaft fixedly connected to the output end of the first motor, a bevel gear fixedly connected to the outer side of the rotating shaft, a pesticide tank fixedly connected to the top of the trolley, a water pump fixedly connected to the bottom wall inside the pesticide tank, a three-way valve fixedly connected to the output end of the water pump, a delivery pipe fixedly connected to the top of the three-way valve, a connecting frame fixedly connected to the end of the delivery pipe away from the water pump, a rotating column rotatably connected inside the connecting frame, a bevel gear fixedly connected to the outer side of the rotating column, multiple stirring rods fixedly connected to the outer side of the rotating column, a nozzle fixedly connected to the side of the stirring rod away from the rotating column, a water pipe fixedly connected to the front end of the three-way valve, and a spray column fixedly connected to the end of the water pipe away from the water pump.

[0006] As a further description of the above technical solution: a second motor is fixedly connected to the outer side of the base, a threaded rod is fixedly connected to the output end of the second motor, a slider is threadedly connected to the outer side of the threaded rod, a fixed rod is rotatably connected to the outer side of the slider, a connecting rod is rotatably connected to the outer side of the fixed rod, and vertical supports are fixedly connected to both ends of the connecting rod.

[0007] As a further description of the above technical solution: the first bevel gear and the second bevel gear mesh with each other.

[0008] As a further description of the above technical solution: the outer side of the rotating shaft is rotatably connected to the inside of the pesticide tank.

[0009] As a further description of the above technical solution: the spray column is fixedly connected to the outside of the fixed rod.

[0010] As a further description of the above technical solution: the connecting frame is fixedly connected to the inside of the pesticide barrel, and the outer side of the delivery pipe is fixedly connected to the inside of the pesticide barrel.

[0011] As a further description of the above technical solution: the three-way valve is fixedly connected to the inside of the pesticide tank on the outside, and the rotating column is rotatably connected to the middle of the pesticide tank on the outside.

[0012] As a further description of the above technical solution: the vertical bracket is rotatably connected to both sides of the base on the side closest to the second motor.

[0013] As a further description of the above technical solution: the two ends of the threaded rod are respectively rotatably connected to the upper and lower sides of the base.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the rotating shaft driven by the motor drives the bevel gear, which in turn drives the rotating column fixed inside to rotate, thereby driving the stirring rod to rotate. When less than half of the pesticide has been used, the three-way valve can be opened to allow the pesticide at the bottom to enter the delivery pipe and be sprayed at the nozzle. This achieves more uniform mixing of the pesticide solution through stirring, and when less than half of the pesticide solution has been used, the pesticide solution can be fully utilized by spraying to clean the inner wall without affecting the next use.

[0015] 2. In this utility model, the second motor drives the threaded rod to rotate, causing the slider to move upward. With the connection rod and the vertical bracket fixed, the spray column fixedly connected to the fixed rod changes from a vertical state to a horizontal state, which realizes that the spraying angle can be changed when facing plants of different heights, thereby improving efficiency.

A bevel gear 203 is fixedly connected to the outside of the rotating column 204; the rotation of the bevel gear 203 drives the rotating column 204 to rotate. Multiple stirring rods 205 are fixedly connected to the outside of the rotating column 204, driving the stirring rods 205 to stir the cleaning solution. A nozzle 206 is fixedly connected to the side of the stirring rod 205 away from the rotating column 204; the nozzle 206 can clean the inner wall when the solution level is below half. A water pipe 5 is fixedly connected to the front end of a three-way valve 209, serving as the main channel for spraying the cleaning solution. A spray column 606 is fixedly connected to the end of the water pipe 5 away from the water pump 210, serving as the main device for spraying.

[0020] Reference Figures 1-2A second motor 6 is fixedly connected to the outer side of the base 2, providing power for the angle changing device. A threaded rod 601 is fixedly connected to the output end of the second motor 6. A slider 602 is threadedly connected to the outer side of the threaded rod 601, so that the threaded rod 601 can drive the slider 602 to move upward when it rotates. A fixed rod 603 is rotatably connected to the outer side of the slider 602. The upward movement of the slider 602 can drive the fixed rod 603 to flip. A connecting rod 604 is rotatably connected to the outer side of the fixed rod 603. Vertical brackets 605 are fixedly connected to both ends of the connecting rod 604, so that the fixed rod 603 can finally be kept in a horizontal state after the flip is completed.

[0021] Reference Figure 1 and Figure 3 The first bevel gear 202 meshes with the second bevel gear 203, and driving the first bevel gear 202 can make the second bevel gear 203 rotate together.

[0022] Reference Figure 1 and Figure 3 The outer side of the rotating shaft 201 is rotatably connected to the inside of the pesticide barrel 4, so that the first motor 3 can drive the bevel gear 202 inside the pesticide barrel 4 to rotate.

[0023] Reference Figures 1-2 The spray column 606 is fixedly connected to the outside of the fixed rod 603, so that when the fixed rod 603 rotates, it drives the spray column 606 to rotate back and forth.

[0024] Reference Figure 1 and Figure 3 The connecting frame 207 is fixedly connected inside the pesticide tank 4, fixing the delivery pipe 208 and the rotating column 204, so that the liquid pesticide inside the delivery pipe 208 can enter the rotating column 204. The outside of the delivery pipe 208 is fixedly connected inside the pesticide tank 4 to provide stability when the delivery pipe 208 transports the liquid pesticide.

[0025] Reference Figure 1 and Figure 3 The three-way valve 209 is fixedly connected to the inside of the pesticide tank 4, so that the pesticide liquid inside the pesticide tank 4 can enter the delivery pipe 208 and the water pipe 5 through the water pump 210. The rotating column 204 is rotatably connected to the middle of the pesticide tank 4, providing stability to the rotating column 204 when rotating.

[0026] Reference Figures 1-2 The vertical bracket 605 is rotatably connected to both sides of the base 2 on the side closest to the second motor 6, so that the fixing rod 603 can remain horizontal after being flipped.

[0027] Reference Figures 1-2 The two ends of the threaded rod 601 are rotatably connected to the upper and lower sides of the base 2, respectively, to provide stability for the threaded rod 601 during rotation.

[0028] Working principle: When the required pesticide is poured into the pesticide tank 4, the operator starts the first motor 3 to drive the rotating shaft 201. The rotating shaft 201 drives the bevel gear 202 to rotate, which in turn drives the meshing bevel gear 203, thereby driving the rotating column 204 to rotate. The rotating column 204 drives the spray nozzle 206 fixed on the outside, which plays a stirring role. The operator starts the water pump 210 to deliver the pesticide into the water pipe 5, and then through the water pipe 5 to the spray column 606 for spraying. However, when half of the pesticide has been used, the three-way valve 209 is turned to allow the pesticide to enter the delivery pipe 208 and be transmitted to the connecting frame 207. Through the connecting frame 207, the pesticide enters the rotating column 204, and through the rotating column 204, it is transmitted to the spray nozzle fixed on the outside of the stirring rod 205. The head 206 performs a 360° rotational spray, ensuring that the pesticide on the inner wall is fully utilized and does not stick to the inner wall, affecting the next use. When it is necessary to spray some low-growing crops, the operator starts the second motor 6 to drive the threaded rod 601 to rotate, causing the slider 602 threadedly connected to the outside of the threaded rod 601 to move upward, driving the fixed rod 603 to rotate. Since the fixed rod 603 is rotatably connected to the outside of the connecting rod 604, and vertical brackets 605 are fixedly connected to both ends of the connecting rod 604, the vertical brackets 605 are rotatably connected to both sides of the base 2, causing the fixed rod 603 to flip from a vertical state to a horizontal state, thereby allowing the spray column 606 fixed on the outside to spray horizontally, making it more efficient when spraying low-growing crops.
