Description

Technical Field

[0001] This utility model relates to the field of chili cultivation technology, specifically to a pest and disease prevention device for chili cultivation. Background Technology

[0002] Chili peppers, as an important economic crop in my country, face serious threats from pests and diseases in both greenhouse and open-field cultivation. Common diseases include anthracnose, blight, and viral diseases, while pests mainly include thrips, whiteflies, and tobacco budworms. These pests and diseases can lead to a 20%-50% reduction in chili pepper yield, and in severe cases, even total crop failure. Current pest and disease control devices used in chili pepper cultivation have the following technical shortcomings: traditional spraying devices are mostly fixed-height and fixed-angle frame structures, which cannot be flexibly adjusted according to the plant height and canopy width at different growth stages such as seedling and mature plant stages. This results in either incomplete coverage (missing the top or bottom of the plant) or waste of pesticides (spraying beyond the plant's distribution area), leading to poor control effects. Therefore, improvements to existing technologies are needed. Summary of the Invention

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: In this technical solution, a pest and disease control device for chili cultivation includes four rectangular main support rods 1. An adjusting main cylinder 2 is fitted onto the upper end of each main support rod 1. An adjusting secondary cylinder 3 is installed between two sets of adjusting main cylinders 2, and a supporting secondary rod 4 is installed between the two adjusting secondary cylinders 3. A fixed seat 11 is fitted at the center between the two supporting secondary rods 4. Spraying rods 5 are installed on both sides of the fixed seat 11. A liquid storage cylinder 6 is installed inside the fixed seat 11, and three high-pressure pumps are installed inside the liquid storage cylinder 6. Fixed cylinders 15 are installed at both ends and the lower end of the spraying rods 5 away from the liquid storage cylinder. A fixing hoop 16 is installed on the side wall of the fixed cylinder 15. An adapter pipe 18 is installed inside the fixing hoop 16. A high-pressure nozzle 17 is installed at the lower end of the adapter pipe 18. A high-pressure pipe 14 is fitted to the output end of the high-pressure pump, and the high-pressure pipe 14 is connected to the adapter pipe 18.

[0017] In practical implementation, the main support rod 1 is made of high-strength aluminum alloy with an anodized surface, possessing corrosion resistance and bending resistance, suitable for humid field environments. The inner diameter of the adjusting main cylinder 2 is slightly larger than the outer diameter of the main support rod 1. Lubricating grease is applied to the inner wall, and the adjusted height is fixed by threaded clips or pins, allowing for flexible adjustment to meet the plant height requirements from seedling to mature chili pepper stages. The adjusting auxiliary cylinder 3 adopts a hollow square tube structure, with both ends bolted to the adjusting main cylinder 2 via flanges. The two adjusting auxiliary cylinders 3 are set parallel to each other, with the spacing designed according to the chili pepper planting row spacing. The supporting auxiliary rod 4 is a cylindrical steel pipe, welded perpendicularly to the adjusting auxiliary cylinder 3 to form a stable rectangular frame structure, ensuring the overall load-bearing capacity of the device. The fixing seat 11 is a rectangular hollow structure, bolted to the center joint of the two supporting auxiliary rods 4. An internal groove for the liquid storage cylinder 6 is provided, with buffer rubber pads pasted on the groove walls to reduce vibration transmission during high-pressure pump operation. The spray bar 5 is a hollow round tube, connected to the side wall of the fixing base 11 by a flange, with both ends sealed. An internal channel is provided for the high-pressure pipe 14 to pass through. The fixing cylinders 15 on each spray bar 5 are evenly distributed to ensure uniform spray coverage. The liquid storage tank 6 is made of food-grade PE material, with a capacity of 20-30L. It has a filling port and a liquid level observation window at the top, and a drain valve at the bottom for easy cleaning and maintenance. Three high-pressure pumps, model miniature high-pressure diaphragm pumps, are installed at both ends of the spray bar 5 and the center high-pressure nozzle 17, respectively. They are independently powered and controlled, and can be started individually or operated synchronously. The high-pressure pipe 14 is made of high-pressure resistant nylon tubing, connected to the output end of the high-pressure pump and the adapter pipe 18 via quick connectors. The connection is reinforced with clamps to prevent high-pressure leakage. The fixed cylinder 15 is welded to the spray rod 5, and the side wall has a pre-drilled mounting hole for the fixing hoop 16. The fixing hoop 16 is a two-part stainless steel structure, which is tightened with bolts to wrap the adapter pipe 18. The adapter pipe 18 can rotate 360° inside the fixing hoop 16 to facilitate adjustment of the spraying direction. Its lower end is threadedly connected to the high-pressure nozzle 17. The high-pressure nozzle 17 is an atomizing nozzle to ensure that the agent is evenly adhered to the plant surface.

[0018] In some technical solutions, the side wall of the transfer pipe 18 is provided with a rotating port, and an adjusting rod 19 is installed inside the rotating port. A closed rotating plate 198 is installed at the end of the adjusting rod 19.

[0019] In practical implementation, the transfer pipe 18 is a T-shaped hollow pipe with a rotating port on its side wall located in the middle of the branch pipe. This port is clearance-fitted with the outer diameter of the adjusting rod 19, ensuring flexible rotation of the adjusting rod 19 without leakage. The adjusting rod 19 is a cylindrical stainless steel rod, with its end fixed to the sealing rotating plate 198 by welding or integral molding. The sealing rotating plate 198 is a circular stainless steel plate that can rotate 0-90° within the branch pipe, allowing for complete opening or closing of the nozzle channel.

[0020] In some technical solutions, the outer wall of the closed rotating plate 198 is fitted with a sealing gasket 199.

[0021] In practical implementation, the sealing gasket 199 is made of fluororubber resistant to pesticide corrosion. Its inner wall has an annular groove, which is embedded in the outer wall slot of the sealing rotating plate 198, ensuring a tight fit without looseness. When the sealing rotating plate 198 is closed, the sealing gasket 199 is in close contact with the inner wall of the branch pipe of the connecting pipe 18, forming a double-sealing structure that effectively prevents high-pressure pesticide leakage. During rotation, the sealing gasket 199 rotates synchronously with the sealing rotating plate 198, reducing frictional wear against the pipe wall and extending its service life.

[0022] In some technical solutions, a circular groove 191 is provided at the bottom end of the adjusting rod 19, and an adjusting shaft 193 is vertically installed inside the circular groove 191. The adjusting shaft 193 is rotatably installed in the rotating port, and the closed rotating plate 198 is connected to the end of the adjusting shaft 193.

[0023] In the specific implementation process, the depth of the circular groove 191 at the bottom of the adjusting rod 19 is set such that its inner diameter is slightly larger than the outer diameter of the adjusting shaft 193. The adjusting shaft 193 is a stainless steel round shaft, vertically welded to the center of the bottom of the circular groove 191, with its lower end extending to the outside of the rotating port and keyed to the closed rotating plate 198, ensuring that the closed rotating plate 198 can rotate synchronously when the adjusting rod 19 rotates. A miniature deep groove ball bearing is installed at the connection between the adjusting shaft 193 and the rotating port. The outer ring of the bearing is interference-fitted with the inner wall of the rotating port, and the inner ring is tightly fitted with the adjusting shaft 193, reducing rotational resistance and making the adjustment operation smoother, while avoiding wear caused by direct friction between the adjusting shaft 193 and the rotating port.

[0024] In some technical solutions, a retaining ring 196 is installed on the upper outer end of the adjusting shaft 193, and an annular pressure plate 195, a spring 197 and an annular rubber sheet 192 are fitted on the circumferential surface of the adjusting shaft 193. A compression block 194 is installed at the upper edge of the annular rubber sheet 192.

[0025] In the specific implementation process, the fixing ring 196 is a stainless steel ring structure, welded to the upper outer end of the adjusting shaft 193, and coaxially arranged with the adjusting shaft 193, serving as a limit. The annular pressure plate 195 is made of hard plastic, fitted onto the adjusting shaft 193 and located below the fixing ring 196; the spring 197 is a stainless steel compression spring, fitted below the annular pressure plate 195, and is in a pre-compressed state; the annular rubber sheet 192 is made of wear-resistant nitrile rubber, with its inner wall tightly fitted to the adjusting shaft 193 and its outer wall clearance-fitted to the inner wall of the rotating port. The extrusion block 194 is a semi-circular rubber block, symmetrically installed on the upper edge of the annular rubber sheet 192, contacting the lower end face of the annular pressure plate 195. When the adjusting shaft 193 rotates, the elastic pressure of the spring 197 is transmitted to the extrusion block 194 through the annular pressure plate 195, pushing the annular rubber plate 192 to press tightly against the inner wall of the rotating port, forming a dynamic seal to prevent the agent from leaking from the gap of the rotating port; at the same time, the buffering effect of the spring can absorb the vibration during high-pressure spraying, prevent the adjusting shaft 193 from loosening, and ensure the stability of the spraying angle.

[0026] In some technical solutions, a throttle 20 is installed at the end of the adjusting rod 19.

[0027] In practice, the throttle 20 is made of engineering plastic with anti-slip textures on the surface, making it easy to grip and apply force.

[0028] In some technical solutions, a trap 13 is installed at the upper end of the supporting rod 4 on one side, and a motor box 12 is installed at the upper end of the supporting rod 4 on the other side.

[0029] In practical implementation, the trap 13 uses a pheromone trap, which is fixed to the upper end of the supporting rod 4 on one side by a U-shaped buckle. It contains a replaceable lure (targeting major pests of chili peppers such as thrips, whiteflies, and tobacco budworms), and has a collection box at the bottom for easy collection and counting of pests. The trap 13's outer shell is made of waterproof plastic with a protection rating of ≥IP54, resisting wind and rain erosion in the field. The motor box 12 is a rectangular sealed box made of stainless steel, fixed to the upper end of the supporting rod 4 on the other side by bolts. It contains a drive motor, controller, and power interface, compatible with 220V AC power or a 12V DC battery.

[0030] In some technical solutions, a reinforcing rod 7 is installed between the left and right main support rods 1, a wheel frame 8 is installed at the bottom of the main support rod 1, a drive wheel 9 is installed inside the wheel frame 8, and the outer wall of the drive wheel 9 is provided with anti-slip texture 10.

[0031] In the specific implementation process, the reinforcing rod 7 is made of aluminum alloy tubing of the same material as the main supporting rod 1, and is horizontally installed on the lower middle part of the main supporting rod 1 on both sides. Both ends are fixed to the main supporting rod 1 by welding, forming a triangular stable structure to enhance the overall rigidity of the device and prevent the frame from shaking and deforming during high-pressure spraying. The wheel frame 8 is a U-shaped steel plate stamping structure, fixed to the bottom end of the main supporting rod 1 by welding. The wheel frame 8 has reserved space inside for the installation of the drive wheel 9, which is rotatably connected to the drive wheel 9 via a rotating shaft. The drive wheel 9 is made of rubber and uses a solid tire design to prevent punctures from sharp objects in the field. The anti-slip texture 10 on the outer wall is a continuous horizontal stripe or grid pattern, which increases the friction with the ground and prevents slipping on muddy or uneven terrain. The drive wheel 9 has a built-in braking device.
