Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering, and in particular to a spraying device for the prevention and control of agricultural pests and diseases. Background Technology

[0002] In modern agriculture, the backpack sprayer is a widely used spraying device for controlling agricultural pests and diseases. This device typically consists of a reservoir for holding water and pesticides, nozzles, a pump, and a carrying strap. It is designed for easy carrying by farmers during fieldwork, providing an efficient spraying solution. In operation, the user wears the sprayer on their back and uses a manual or electric pump to draw pesticide from the reservoir, then sprays it onto the plant surface through the nozzles. The advantages of the backpack sprayer lie in its convenience and flexibility, making it suitable for small-scale farmland and hard-to-reach areas.

[0003] However, traditional backpack sprayers still have some shortcomings in terms of pesticide mixing and spraying efficiency. For example, the pesticide solution in the storage tank may separate due to prolonged standing, especially when using powdered pesticides. The powder at the bottom tends to settle, making it difficult to mix properly. This results in uneven pesticide concentration during spraying, which may lead to different crop growth patterns in the field or cause crops in some fields that have not reached the required spray concentration to wither, thus affecting the control effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a spraying device for the prevention and control of agricultural pests and diseases, which aims to improve the problem of uneven proportion of pesticide mixtures sprayed by the equipment after the pesticide solution separates or the pesticide powder settles to the bottom.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a spraying device for agricultural pest and disease control, comprising a storage box, a motor 1 installed on the top of the storage box, a rotating column fixedly connected to the output end of the motor 1, an auger fixedly connected to one end of the rotating column, a motor 2 installed inside the storage box, a hollow column fixedly connected to the output end of the motor 2, multiple hollow columns arranged symmetrically on the left and right, each auger rotatably connected inside the hollow column, stirring blades fixedly connected to the outer wall of the hollow column, and a transmission assembly arranged between the hollow columns.

[0006] As a further description of the above technical solution:

[0007] The transmission assembly includes pulleys, each of which is fixedly connected to one end of a hollow column, and a belt is provided between the pulleys.

[0008] As a further description of the above technical solution:

[0009] The storage box is fixedly connected to a connecting column inside, and a support frame is slidably connected to the outer wall of the connecting column. The storage box is also slidably connected to a sliding door.

[0010] As a further description of the above technical solution:

[0011] A magnet is provided at one end of the connecting column, and a magnet is provided inside the support frame.

[0012] As a further description of the above technical solution:

[0013] The first magnet and the second magnet are magnetically repulsive.

[0014] As a further description of the above technical solution:

[0015] Water pumps are installed on both sides of the storage box, and the output end of the water pumps is fixedly connected to a hose.

[0016] As a further description of the above technical solution:

[0017] One end of the flexible tube is fixedly connected to a rigid tube.

[0018] As a further description of the above technical solution:

[0019] The storage box is equipped with a top cover.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the combination of components such as motor, rotating column and auger firstly achieves the effect of guiding the settled liquid back to the top for thorough mixing, which solves the problem that some powdered pesticides are not easy to mix evenly after settling at the bottom, thereby improving the pesticide utilization rate of the equipment, reducing costs and improving the effect of spraying pesticides.

[0022] 2. In this utility model, through the cooperation between components such as hoses, rigid pipes and sliding doors, the equipment can perform spraying operations without manual support when the height is fixed.

[0028] 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.

[0029] Reference Figure 1-3 An embodiment of this utility model provides a spraying device for agricultural pest and disease control, comprising a storage box 1, a motor 3 on the top of the storage box 1, a rotating column 4 fixedly connected to the output end of the motor 3, an auger 5 fixedly connected to one end of the rotating column 4, a motor 6 inside the storage box 1, a hollow column 7 fixedly connected to the output end of the motor 6, multiple hollow columns 7 arranged symmetrically on the left and right, each auger 5 rotatably connected inside the hollow column 7, a stirring blade 8 fixedly connected to the outer wall of the hollow column 7, a transmission assembly between the hollow columns 7, a top cover 2 on the top of the storage box 1, and a transmission assembly including pulleys 9, each pulley 9 fixedly connected to one end of the hollow column 7, and a belt 10 between the pulleys 9;

[0030] Specifically, before spraying, water and pesticides must first be poured into storage tank 1 according to a predetermined ratio. Ensuring accurate liquid ratio is a crucial step in guaranteeing spraying effectiveness; too much or too little pesticide will affect the final spraying result. After the ratio is completed, motor 6 is started, which drives the hollow column 7 to perform stirring. The hollow column 7 transmits power to the stirring blades 8 through the connected synchronous rotating pulley 9, causing them to be evenly stirred within storage tank 1. During stirring, some powdered pesticides may settle to the bottom of the liquid, resulting in uneven mixing, thus requiring further processing. At this time, motor 3 is started, driving the rotating column 4 to rotate, which in turn drives the auger 5 to rotate. The auger 5's function is to use the water flow to push the settled pesticide powder back to the top of storage tank 1. This process ensures that all pesticides and water are fully mixed, avoiding the impact of pesticide powder sedimentation on the spraying effect. Through this series of meticulous operational steps, the efficiency and effectiveness of spraying can be ensured, thereby improving crop production efficiency and quality.

[0031] A connecting column 11 is fixedly connected inside the storage box 1. A support frame 12 is slidably connected to the outer wall of the connecting column 11. An opening door 13 is slidably connected inside the storage box 1. A magnet 17 is provided at one end of the connecting column 11. A magnet 18 is provided inside the support frame 12. Magnet 17 and magnet 18 repel each other magnetically. Water pumps 14 are provided on both sides of the storage box 1. A hose 15 is fixedly connected to the output end of the water pump 14. A rigid pipe 16 is fixedly connected to one end of the hose 15.

[0032] Specifically, during pesticide spraying, the operator only needs to gently support the rigid pipe 16, and the water pump 14 can automatically and efficiently transfer the mixed pesticide solution to the spraying position through the hose 15, achieving precise spraying. This design greatly reduces the manual burden and improves spraying efficiency. When spraying at a fixed height is required, the operator simply pulls the sliding door 13 upwards. At this time, the support frame 12 will release its obstruction to the object, and then, through the repulsive force between magnet 17 and magnet 2 18, it will push the support frame 12 out of the storage box 1. The design of this system ensures that the support frame 12 will not exceed the maximum sliding trajectory of the storage box 1 when sliding, ensuring the stability and safety of the equipment. After the support frame 12 slides out, the rigid pipe 16 can be precisely positioned in the corresponding groove of the support frame 12, forming a stable spraying system. At this time, the spraying operation no longer needs to rely on manual support and can be carried out continuously, ensuring the continuity and uniformity of the spraying process. This innovative design effectively improves the automation level of pesticide spraying operations and reduces errors and inconveniences that may be caused by human factors.

[0033] Working principle: Before spraying, water and pesticides are poured into storage tank 1 in a certain ratio. After pouring, motor 6 is started to drive the hollow column 7 to agitate the mixing blades 8. The hollow column 7 driven by motor 6 is driven by a synchronously rotating pulley 9 and a belt 10, so that both sides of the hollow column 7 can drive the corresponding mixing blades 8 to agitate. In this way, the pesticides and water can be mixed evenly. Some powdered pesticides may settle at the bottom during mixing. At this time, the rotating column 4 driven by motor 3 will drive the auger 5 to rotate, which will cause the settled pesticide powder to be carried by the water flow and transported back to the top of storage tank 1. The mixture is thoroughly stirred and mixed at the designated location. When spraying pesticides, only manual support is needed on the rigid pipe 16 to allow the water pump 14 to transmit the mixed pesticide through the hose 15 for spraying. When spraying at a fixed height without manual adjustment, simply pull the sliding door 13 upwards. At this time, the support frame 12 will no longer be obstructed by any object. Then, through the repulsion between magnet 17 and magnet 18, the support frame 12 is pushed and slides out of the storage box 1. The maximum sliding trajectory will not leave the storage box 1. In this way, the rigid pipe 16 can be set up in the corresponding groove position of the support frame 12 for spraying operations without manual support.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
