Description

Technical Field

[0001] This utility model relates to the field of agricultural pest and disease prevention technology, and in particular to a device for preventing pests and diseases in agricultural greenhouse vegetables. Background Technology

[0002] With the trend of agricultural modernization, greenhouse vegetable cultivation is becoming increasingly popular. The relatively enclosed and unique environment of greenhouses, such as high temperature and high humidity, creates favorable conditions for the reproduction of pests and diseases. Traditional prevention and control methods are often ineffective and have certain limitations. Therefore, the exploration of pest and disease prevention technologies for greenhouse vegetables is extremely important. It is necessary to improve the accuracy of pest and disease monitoring and combine ecological regulation, physical control, and scientific and reasonable agronomic measures to reduce the probability of pest and disease occurrence, ensure the yield and quality of vegetables, and thus meet the growing market demand for high-quality vegetables.

[0003] Traditional pest and disease prevention methods involve manual spraying, which is a serious waste of manpower. In addition, manual spraying results in poor uniformity of pesticide application, causing some vegetables to not be completely sprayed to repel pests.

[0004] An existing patent (public account: CN216358215U) discloses a device for preventing diseases and pests in agricultural greenhouse vegetables. The device includes a frame with an internal slide rail and a guide rail on its inner wall. A servo motor is installed at one end of the frame, with a transmission wheel mounted on it. A fixed pulley, which engages with the transmission wheel, is installed at the end of the frame away from the servo motor. Tooth blocks are installed on the inner wall of the slot. A support rod passing through the slot is installed above the traction seat, and a spraying mechanism is installed above the support rod. This device, through the cooperation of the transmission wheel, fixed pulley, and traction rope, can drag the traction seat on the frame at a uniform speed. This facilitates the traction seat driving the spraying mechanism to move synchronously at a uniform speed, thereby improving the uniformity of pesticide spraying on the vegetables and preventing some vegetables from being missed and thus causing diseases and pests.

[0005] To address the aforementioned problems, existing patents have provided solutions. However, the spray nozzles of existing devices are mostly at a fixed height for spraying insects and killing insect eggs on the surface of vegetables. This makes it difficult to operate effectively when facing greenhouses of different lengths and vegetables of different heights. Moreover, as the vegetables grow, they become more and more densely packed, which greatly reduces the practicality of the device.

[0006] Therefore, a prevention device for diseases and pests in agricultural greenhouse vegetables is proposed. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A device for preventing diseases and pests in agricultural greenhouse vegetables includes a first support column 1 and a second support column 2. A sliding component 3 is provided between the top of the first support column 1 and the second support column 2. An adjustable spray component 4 is provided on the top of the sliding component 3. Mounting plates 5 are bolted to the front side of the first support column 1 and the rear side of the second support column 2. A power motor 6 is bolted to the top of the mounting plate 5. A rope take-up roller 7 is bolted to the output end of the power motor 6.

[0029] The adjustable spray assembly 4 includes a support rod 401. The bottom of the support rod 401 is bolted to the top of the sliding assembly 3. Six stretchable winding reels 402 are bolted to the front side of the support rod 401. The winding reels 402 extend downward and are knotted to connect to buckles 403. Spray pipes 404 are bolted between the bottoms of the buckles 403 on both sides. Several spray nozzles 405 are provided at the bottom of the spray pipes 404.

[0030] In this embodiment: by setting the first pillar 1 and the second pillar 2, the main body support is provided for the sliding assembly 3 and the adjustable spray assembly 4. By bolting the mounting plate 5 to the front side of the first pillar 1 and the rear side of the second pillar 2, a mounting position is provided for the power motor 6 that provides kinetic energy for the movement of the ball slider 306. By bolting the support rod 401 to the top of the sliding assembly 3, the support rod 401 provides a fixed mounting position for the tension reel 402. Furthermore, by connecting the coil of the tension reel 402 to the buckle 403 through the knot, a stable lifting structure is provided for the spray pipe 404 bolted to the bottom of the buckle 403. The tension of the tension reel 402 matches the weight of the spray pipe 404. The spray pipe 404 is positioned by being pulled by the coil of the tension-type winding reel 402 to adjust its height above the ground, thus adapting to vegetables at different stages. The spray head 405 at the bottom of the spray pipe 404 can atomize and spray the pesticide entering the spray pipe 404 under pressure. Since the support rod 401 is bolted to the surface of the sliding component 3, the spray pipe 404 moves with the movement of the ball bearing slider 306, thereby removing pests from vegetables in different locations. The number of sliding components 3 between the two power motors 6 can be set to different lengths according to the length of the greenhouse, so as to adapt to greenhouses of different lengths.

[0031] Specifically, such as Figure 1 , Figure 3 As shown, the sliding component 3 includes a slide rail 301, the bottom of which is bolted to the top of the first support column 1 and the second support column 2 respectively.

[0032] Specifically, such as Figure 3 As shown, the slide rail 301 has a rope groove 302 and a tube groove 303 inside. The front and rear sides of the rope groove 302 and the tube groove 303 are provided with guide rings 304, and the surface of the guide rings 304 is in contact with the inner wall of the slide rail 301. Baffles 305 are bolted to the front and rear sides of both sides of the slide rail 301.

[0033] Specifically, such as Figure 3 As shown, a ball slider 306 is provided on the top of the slide rail 301. The top of the ball slider 306 is bolted to the bottom of the support rod 401. A limit ring 307 is bolted to the front side of the ball slider 306. Pull rings 308 are bolted to the front and rear sides of the bottom of the ball slider 306, and the pull rings 308 are placed inside the rope groove 302.

[0034] In this embodiment: A slide rail 301 is bolted to the top of the first support column 1 and the second support column 2, and a support rod 401 is bolted to the top of the ball bearing slider 306, making the slide rail 301 the moving path of the adjustable spray assembly 4. The ball bearing slider 306 can provide less friction with the slide rail 301, thus making the operation of the sliding assembly 3 smoother and more stable. The rope groove 302 and the tube groove 303 provide the necessary spatial structure for the transmission of the ball bearing slider 306 and the delivery of the medicine. The limiting ring 307 and the guide ring 304 define the transmission process. In the space, the pull ring 308 provides a structural fulcrum for power transmission, while the baffle 305 prevents the ball slider 306 from disengaging from the slide rail 301. By starting the power motor 6, the ball slider 306 can move on the slide rail 301. The support rod 401 bolted to the slide rail 301 drives the stretching reel 402 to move. The pull buckle 403, which is knotted at the bottom of the reel 402, drives the spray pipe 404 bolted to its bottom. The spray head 405 at the bottom of the spray pipe 404 can move with the movement of the ball slider 306 to achieve mobile spraying.

[0035] Specifically, such as Figure 1 , Figure 2 As shown, each of the two spray pipes 404 is fixedly connected to a connecting hose 8 on one side opposite to the other. A three-way pipe 9 is fixedly connected between the two connecting hoses 8. The bottom of the three-way pipe 9 is bolted to the top of the ball bearing slider 306.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a drug delivery hose 10 is fixedly connected to the front side of the three-way pipe 9, and a hose reel 11 is wound around the other end of the drug delivery hose 10. The left side of the hose reel 11 is bolted to the right side of the front rope take-up roller 7, and the surface of the drug delivery hose 10 is in contact with the inner wall of the limiting ring 307 and the guide ring 304.

[0037] In this embodiment: the two spray pipes 404 are fixedly connected to the three-way pipe 9 through the connecting hose 8. The three-way pipe 9 is bolted to the ball slider 306, realizing the relative fixed position of the three-way pipe 9 and the spray pipes 404. The medicine can be transmitted to the two spray pipes 404 through the three-way pipe 9 respectively. Then, the two spray pipes 404 spray through the spray head 405 at the bottom. The drug delivery hose 10 fixedly connected to the front end of the three-way pipe 9 is the carrier of drug delivery. The drug delivery hose 10 moves with the ball slider 306 through the contact between its surface and the inner wall of the limiting ring 307 and the guide ring 304. The process is carried out inside the tube release groove 303. The hose reel 11 connected by the drug delivery hose 10 can realize the change of the opening and closing of the drug delivery hose 10 with the movement of the ball slider 306 to achieve the purpose of real-time drug delivery.

[0038] Specifically, such as Figure 2As shown, pull ropes 12 are provided on opposite sides of the two pull rings 308. The other ends of the two pull ropes 12 are respectively wound and connected to the front and rear winding rollers 7. The surface of the pull ropes 12 is in contact with the inner wall of the guide ring 304.

[0039] Specifically, such as Figure 4 , Figure 5 As shown, a rotary anti-winding connector 13 is fixedly connected to the right side of the hose reel 11, a supply pipe 14 is fixedly connected to the right side of the rotary anti-winding connector 13, an integrated medicine supply tank 15 is fixedly connected to the bottom of the supply pipe 14, and a control panel 16 is bolted to the top of the integrated medicine supply tank 15.

[0040] In this embodiment: the reverse rotation of the front take-up roller 7 pulls the pull rope 12, which in turn pulls the ball slider 306 forward on the slide rail 301. The forward rotation of the rear take-up roller 7 pulls the wound pull rope 12, which in turn pulls the ball slider 306 backward on the slide rail 301. Simultaneously, the rear take-up roller 7 releases while the front take-up roller 7 pulls the pull rope 12, allowing the front pull rope 12 to pull the ball slider 306. In this device, the front power motor 6 reverses, and the rear power motor 6 reverses synchronously. The front power motor 6 drives the take-up roller 7 and the tube reel 11 to reverse, thereby achieving the pulling and retraction of the pull rope 12 and the drug delivery hose 10. After the pull rope 12 contacts the inner wall of the guide ring 304, it connects to the pull ring 308, causing the pull rope 12 to be pulled into the rope release groove 302. The pull ring 308 drives the bolted ball slider 306 to move on the slide rail 301. The hose reel 11 also retracts the drug delivery hose 10 as the front motor 6 reverses, adapting it to the movement of the ball bearing slider 306. The rear motor 6 rotates synchronously, releasing the pull rope 12 on the rear take-up roller 7 to adapt to the movement of the ball bearing slider 306 on the slide rail 301. The integrated drug supply tank 15 delivers the drug to the supply pipe 14. The drug enters the drug delivery hose 10 through the rotating anti-tangle connector 13. The drug delivery hose 10 divides the drug into two streams through the three-way pipe 9. The two streams of drug enter the spray pipe 404 through the connecting hose 8. The drug in the spray pipe 404 is sprayed through the spray head 405 under the action of internal pressure. During the spraying process, the spray position can be changed as the ball bearing slider 306 moves. The control panel 16 can set different settings such as the drug delivery pressure, the rotation speed and duration of the motor 6, etc., to adapt to different working requirements.

[0041] Working principle: When using this device, firstly, according to the height of the vegetables, the spray pipe 404 is pulled. The spray pipe 404 moves the pull buckle 403. The pull buckle 403, through the knotted pull rope 12, pulls the coiled wire in the stretch-type winding reel 402 to the specified distance and automatically fixes the length. Through the adapter connecting hose 8, the opposite sides of the two spray pipes 404 are fixedly connected to the three-way pipe 9. At this time, the integrated medicine supply tank 15 is activated. The medicine supply tank transfers the medicine to the supply pipe 14. The medicine in the supply pipe 14 is delivered to the medicine delivery hose 10 through the rotating anti-tangle connector 13. The medicine in the medicine delivery hose 10... The solution is divided into two streams via a three-way connector 9. These two streams of solution then enter the spray pipe 404 through a connecting hose 8. Under internal pressure, the solution in the spray pipe 404 is sprayed through the spray head 405. The support rod 401 provides a fixed mounting position for the tension reel 402 and, through the knotted connection of the reel 402 to the pull buckle 403, provides a stable lifting structure for the spray pipe 404, which is bolted to the bottom of the pull buckle 403. The tension of the tension reel 402 matches the weight of the spray pipe 404. Simultaneously, the power motor 6 is activated: when the front power motor 6 reverses, it drives the winding roller. 7 and the hose reel 11 reverse, thereby pulling and retracting the pull rope 12 and the drug delivery hose 10. After the pull rope 12 contacts the inner wall of the guide ring 304, the rope clamp connects to the pull ring 308, placing the pull rope 12 in the rope release groove 302. The pull ring 308 drives the bolted ball slider 306 to move on the slide rail 301. The drug delivery hose 10 is retracted as the front power motor 6 reverses, adapting to the movement of the ball slider 306. The rear power motor 6 rotates synchronously, releasing the pull rope 12 on the rear rope take-up roller 7 to adapt to the movement of the ball slider 306. The front and rear power motors 6 rotate forward or reverse simultaneously to perform the pulling action. Alternatively, when the front motor 6 reverses, it pulls the rope 12 and the delivery hose 10 through the rope take-up roller 7 and the hose reel 11, and drives the ball block slider 306 to move. At this time, the rear rope take-up roller 7 releases the rope 12 on it. Conversely, when the rear rope take-up roller 7 performs the rope take-up action, the front rope take-up roller 7 and the hose reel 11 release accordingly. The control panel 16 can set parameters such as delivery pressure, motor speed and duration to adapt to different working needs. This device achieves directional spraying to kill insects through the guide rail path, thereby achieving the purpose of pest and disease prevention.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
