Description

Technical Field

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

[0002] With the continuous advancement of agricultural technology, greenhouse vegetable cultivation has become increasingly mature and widely applied. Greenhouse cultivation provides vegetables with a relatively stable growing environment, effectively resisting the impact of adverse external weather conditions, ensuring vegetable yield and quality, and meeting the market's continuous demand for fresh vegetables.

[0003] Currently, the mainstream method for spraying crops in greenhouses is still manual backpack sprayers. Operators need to carry heavy sprayers for long periods of time and manually spray while walking between rows. On the one hand, manual spraying is extremely labor-intensive, which not only affects work efficiency, but may also lead to improper spraying operation due to physical fatigue, thus affecting the spraying effect.

[0004] On the other hand, due to factors such as physical strength and attention, the amount of pesticides sprayed in different areas may vary greatly, with some being more and some less. Too much pesticides will cause pesticide residues to exceed the standard, which will have an adverse effect on the quality of vegetables, while too little pesticides will not be able to effectively control pests and diseases, leading to a reduction in vegetable yield.

[0005] Furthermore, operators are directly exposed to pesticide mist for extended periods, and even with protective gear, there is still a high risk of health problems. They are easily poisoned through inhalation and skin contact, posing a serious threat to human health. Utility Model Content

[0006] In view of the problems of extremely high labor intensity and uneven spraying in existing manual spraying methods, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a mechanized spraying device for agricultural production, which is to adapt to the greenhouse ridge cultivation environment, replace manual labor, and achieve efficient, uniform, and safe spraying.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mechanized spraying device for agricultural production, including a support platform, a self-driving component installed on the top of the support platform, a walking plate that travels on the support platform fixed to the driving end of the self-driving component, a pesticide cartridge fixed to the top of the walking plate by a pad column, a liquid pump installed on the top of the walking plate and below the pesticide cartridge, and the inlet end of the liquid pump connected to the outlet end of the pesticide cartridge at the bottom, the outlet end of the liquid pump fixedly connected to the inlet end of a flow equalization chamber, and spraying components detachably provided at the outlets at both ends of the flow equalization chamber;

[0009] The self-driving component includes a toothed guide rail structure fixed to the upper surface of the support plate, and a connecting block slidably mounted on the upper surface of the toothed guide rail structure. A drive motor is mounted on the outer side of the top of the connecting block, and a gear that meshes with the toothed end of the toothed guide rail structure is mounted on the output end of the drive motor.

[0010] As an improved technical solution, limit pulleys are installed at the four corners of the bottom of the connecting block, and the limit pulleys slide in a limited manner with the guide end of the toothed guide rail structure. A control box is fixed at the connection between the traveling plate and the connecting block.

[0011] As an improved technical solution, the toothed guide rail structure includes straight toothed guide rails arranged in a cross-shaped staggered configuration, and an arc-shaped toothed guide rail is fixed between the opposite ends of the two straight toothed guide rails.

[0012] As an improved technical solution, the spray assembly includes a connecting pipe that is detachably installed at the outlet end of the flow equalization chamber, a spray pipe that is detachably installed at the outlet end of the connecting pipe, and a row of spray nozzles installed at the outlet end of the bottom of the spray pipe.

[0013] As an improved technical solution, hollow external threaded pipes are welded to the two water outlets at the bottom of the flow equalization chamber and the water outlet of the connecting pipe, a spray pipe is welded to the water inlet of the spray pipe, and a second internal threaded sleeve is welded to the water inlet of the connecting pipe.

[0014] As an improved technical solution, a stirring assembly is installed on the top of the cartridge. The stirring assembly includes a frame and a servo motor installed on the top of the frame. The output shaft of the servo motor is equipped with a stirring shaft, and a stirring blade is installed at one end of the stirring shaft located inside the cartridge.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model achieves a detachable connection between the flow equalization chamber and the connecting pipe by connecting the first internal threaded sleeve to the hollow external threaded pipe at the water outlet end of the flow equalization chamber. By setting connecting pipes of different sizes, the appropriate size connecting pipe can be selected according to the different crop heights, so that the spray pipe and the crop are at the optimal spraying height, ensuring the spraying effect and adapting it to different heights.

[0017] 2. This utility model achieves a detachable connection between the spray pipe and the connecting pipe by connecting the second internal threaded sleeve to the hollow external threaded pipe at the water outlet end of the connecting pipe. The spray pipe can be rotated to fit the width of each row, ensuring that the spray pipe can completely cover the width of the crops between rows and improving the comprehensiveness of crop spraying.

[0018] 3. This utility model uses a self-driving component to drive the pesticide cartridge and nozzle to move along the crop rows, spraying the pesticide onto each row of crops while moving. It can achieve automated spraying of large-area greenhouses without manual driving, significantly improving work efficiency and saving a lot of labor costs. At the same time, the uniform forward spraying effectively improves the uniformity and comprehensiveness of spraying, ensuring the control effect. Furthermore, during spraying, the pesticide is separated from the person, avoiding direct contact with the pesticide, greatly reducing the risk of poisoning and protecting the health and safety of personnel.

[0029] The self-driving component 2 drives the spray cylinder 4 and the nozzle 83 to move along the crop rows, spraying the pesticide onto each row of crops while moving. This achieves automated spraying of large-area greenhouses without manual intervention, significantly improving work efficiency and saving a lot of labor costs. At the same time, the uniform forward spraying effectively improves the uniformity and comprehensiveness of spraying, ensuring the control effect. Furthermore, the separation of people and pesticides during spraying avoids direct contact with pesticides, greatly reducing the risk of poisoning and protecting the health and safety of personnel.

[0030] Limiting pulleys 27 are installed at the four corners of the bottom of the connecting block 21, and the limiting pulleys 27 slide in a limited manner with the guide end of the toothed guide rail structure 23. A control box 5 is fixed at the connection between the walking plate 3 and the connecting block 21. A battery and a controller are installed inside the control box 5.

[0031] The toothed guide structure 23 includes straight toothed guides 24 arranged in a cross-shaped staggered manner, and an arc-shaped toothed guide 25 is fixed between the opposite ends of the two straight toothed guides 24. The toothed guide structure 23 with different paths can be formed by multiple straight toothed guides 24 and multiple arc-shaped toothed guides 25.

[0032] The spray assembly 8 includes a detachable connecting pipe 81 installed at the outlet end of the flow equalization chamber 7, and the connecting pipe 81 is L-shaped. A spray pipe 82 is detachably installed at the outlet end of the connecting pipe 81. A row of spray nozzles 83 is installed at the outlet end of the bottom of the spray pipe 82, and the spray nozzles 83 are connected to the interior of the spray pipe 82.

[0033] Hollow external threaded pipes are welded to the two water outlets at the bottom of the flow equalization chamber 7 and the water outlet of the connecting pipe 81.

[0034] The assembly process for spray assembly 8 is as follows:

[0035] The first internal threaded sleeve 84 is connected to the hollow external threaded pipe at the water outlet of the equalization chamber 7 by threading, so that the equalization chamber 7 and the connecting pipe 81 can be detached. By setting different sizes of connecting pipes 81, the appropriate size of connecting pipe 81 can be selected according to the different crop heights, so that the spray pipe 82 and the crop are at the optimal spraying height, ensuring the spraying effect and adapting it to different heights.

[0036] The second internal threaded sleeve 85 is connected to the hollow external threaded pipe at the water outlet end of the connecting pipe 81 by threading, so that the spray pipe 82 and the connecting pipe 81 can be detachably connected. The spray pipe 82 can be rotated to fit the width of each row, so that the spray pipe 82 can completely cover the width of the crops between rows, thus improving the comprehensiveness of crop spraying.
