Description

Technical Field

[0001] This utility model belongs to the field of agricultural plant protection machinery technology, specifically relating to a high-efficiency atomization auxiliary spraying device for pesticides in paddy fields. Background Technology

[0002] Pesticide spraying devices are key tools for the prevention and control of agricultural pests and diseases. Their background technology can be traced back to the manual sprayers of the 19th century. With the development of mechanization in the 20th century, spraying equipment such as backpack sprayers and tractor-mounted sprayers emerged, and hydraulic, pneumatic and electronic control technologies were gradually incorporated to improve atomization effects and operational efficiency. The development process has undergone technological iterations from manual to motorized, and from extensive spraying to precise variable-rate application. In recent years, the combination of drones and intelligent sensing technology has enabled efficient and low-pollution aerial spraying and precision agriculture applications. Application scenarios cover large-scale planting fields such as field crops, orchards, and greenhouses, as well as non-agricultural scenarios such as urban greening and sanitation and epidemic prevention. Modern intelligent spraying systems, through technologies such as GPS and the Internet of Things, further optimize pesticide utilization and reduce environmental pollution, becoming an important part of smart agriculture.

[0003] In existing technologies, traditional pesticide spraying devices for paddy fields generally suffer from problems such as poor atomization, serious pesticide drift loss, and insufficient coverage of dead corners in the field. In particular, manual or backpack sprayers rely on manual operation, which is inefficient and prone to uneven application. Meanwhile, large-scale mechanized spraying equipment is difficult to adapt to the complex terrain conditions of paddy fields, resulting in low pesticide utilization and increased environmental pollution risks.

[0025] Example

[0026] Reference Figures 1-4 This embodiment of the present invention provides a high-efficiency atomization-assisted spraying device for pesticides in paddy fields, comprising:

[0027] The vehicle frame 101, the engine 102 adapted to be mounted on the surface of the vehicle frame 101, the drive wheel 103 adapted to be mounted on the surface of the vehicle frame 101, the handrail 104 fixedly connected to the surface of the vehicle frame 101, the load-bearing component 105 disposed on the surface of the vehicle frame 101, the sprinkler assembly 106 fixedly connected to the side wall of the load-bearing component 105, the connecting component 107 fixedly connected to the side wall of the sprinkler assembly 106, and the auxiliary component 108 fixedly connected to the side wall of the load-bearing component 105;

[0028] The connecting assembly 107 includes a female seat 107a, a top spring 107b fixedly connected to the inner wall of the female seat 107a, a first piston 107c fixedly connected to the end of the top spring 107b, a return spring 107d sleeved on the surface of the female seat 107a, a collar 107e fixedly connected to the end of the return spring 107d, a steel ball 107f movably connected to the inner wall of the collar 107e, a male seat 107g movably connected to the inner wall of the female seat 107a, a compression spring 107h fixedly connected to the inner wall of the male seat 107g, and a second piston 107i fixedly connected to the end of the compression spring 107h.

[0029] Specifically, the load-bearing assembly 105 includes a tow frame 105a hinged to the surface of the frame 101, a caster wheel 105b adapted to be installed at the bottom of the tow frame 105a, a mounting bracket 105c fixedly connected to the side wall of the tow frame 105a, and a mounting seat 105d fixedly connected to the side wall of the mounting bracket 105c. The sprinkler assembly 106 includes a water tank 106a fixedly connected to the inner wall of the mounting bracket 105c, and a power supply box 106b fixedly installed to the side wall of the mounting seat 105d.

[0030] The power supply box 106b has a battery fixedly installed inside to ensure that it can provide power to the water pump 106c and ensure that the water pump 106c runs smoothly. Mixing pesticides in the water tank 106a can ensure the convenience of pesticide spraying and increase the spraying range.

[0031] The sprinkler assembly 106 also includes a water pump 106c fixedly connected to the side wall of the mounting base 105d, and a spraying frame 106d fixedly connected to the side wall of the mounting frame 105c. The auxiliary assembly 108 includes a connecting frame 108a fixedly connected to the side wall of the traction frame 105a, and a support frame 108b fixedly connected to the side wall of the connecting frame 108a.

[0032] Furthermore, the spray frame 106d ensures that after the water pump 106c draws the pesticide solution, the spray frame 106d can atomize the solution and spray it over a wide area of ​​crops.

[0033] Preferably, the auxiliary assembly 108 further includes a take-up roller 108c connected to the inner wall of the support frame 108b via a bearing, and a crank handle 108d fixedly connected to the side wall of the take-up roller 108c. The auxiliary assembly 108 also includes a connecting hose 108e wound around the surface of the take-up roller 108c, and a spray gun 108f connected to the end of the connecting hose 108e.

[0034] It should be noted that a connector 107g is fixedly installed at the interface of the connecting hose 108e and the spray frame 106d, ensuring that the connecting hose 108e and the spray frame 106d can be quickly replaced at the port of the water pump 106c; the spray gun 108f, in conjunction with the setting of the connecting hose 108e, can spray the dead corners of the spray frame 106d, ensuring that there are no dead corners in the pesticide spraying.

[0035] In use, start the engine 102. The engine 102, together with the drive wheel 103, moves the frame 101. The frame 101 moves the traction frame 105a. After the pesticide is mixed, put it into the water tank 106a. Move the collar 107e to release the steel ball 107f. Insert the male connector 107g on the interface of the spray frame 106d into the female connector 107a. Release the collar 107e. The collar 107e abuts against the steel ball 107f. The steel ball 107f abuts against the surface of the male connector 107g, fixing the male connector 107g. The second piston 107i pushes the first piston 107c. The two pistons are under force and move in opposite directions simultaneously, connecting the male connector 107g with the female connector 106a. The pipes between 7a are connected. The water pump 106c is started. The water pump 106c draws the liquid pesticide from the water tank 106a and the liquid pesticide enters the spray frame 106d. The liquid pesticide is continuously drawn by the water pump 106c and atomized through the opening of the spray frame 106d to spray the crops. When encountering a dead corner in the spraying, the sub-socket 107g at the interface of the spray frame 106d is removed. The sub-socket 107g at the end of the connecting hose 108e is inserted into the female socket 107a. The spray gun 108f is pulled to aim the spray gun 108f at the dead corner for spraying. After the spraying is completed, the handle is turned. The handle drives the take-up roller 108c to rotate and put the connecting hose 108e back in.

[0036] In summary, through the cooperation of various components, rapid switching of spraying modes and coverage of blind spots are achieved. The load-bearing component 105 and the spraying component 106 mounted on the chassis 101 constitute the basic spraying system. The water pump 106c powered by the power supply box 106b, together with the atomizing spray frame 106d, achieves large-area uniform spraying. The connecting component 107 adopts a spring piston linkage structure and a steel ball 107f locking mechanism. The quick switching between the spray frame 106d and the connecting hose 108e is achieved through the insertion and removal of the male and female connectors 107a. The retractable auxiliary component 108 ensures the airtightness of the main pipeline and the efficiency of pesticide flow, while also quickly switching to a handheld spray gun 108f mode for precise respraying. The device combines the efficiency of mechanized operations with the flexibility of manual operation. The design of the traction frame 105a and universal wheels 105b reduces the burden of field movement, while the structure of the retractable roller 108c optimizes pipeline management efficiency. Overall, it improves the uniformity of pesticide coverage and terrain adaptability, while reducing the labor intensity of operators.
