Abstract
Description
Technical Field
[0001] This utility model relates to the field of pest and disease control technology, specifically to a spraying device for pest and disease control. Background Technology
[0002] Pest and disease control refers to the monitoring, forecasting, prevention, control, and emergency response of harmful organisms such as diseases, insects, weeds, and rodents that damage crops and their products, as well as their supervision and management. Currently, the common method of controlling crop pests and diseases is to spray pesticides on the leaves of the affected plants to treat the pests and diseases with chemicals.
[0003] Currently, when using sprayers for crops, workers can use the nozzles to spray pesticides around the crops. The pesticides then fall onto the surface of the crop leaves for absorption. However, because the front of the leaves is exposed to sunlight year-round and undergoes strong photosynthesis, the pesticides are easily decomposed by sunlight when sprayed on the front, affecting absorption. If workers rotate the nozzles to spray, the pesticides are easily lifted upwards at the moment of spraying, posing a threat to the health of the workers. Utility Model Content
[0004] The purpose of this invention is to provide a spraying device for pest and disease control, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for pest and disease control, comprising an arc-shaped frame, and further comprising:

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.
[0022] Please see Figure 1-5As shown, a spraying device for pest and disease control includes an arc-shaped frame 1. A rectangular plate 2 is fixedly connected to the surface of the arc-shaped frame 1. U-shaped plates 3 are fixedly connected to the top and bottom of the arc-shaped frame 1. A groove 4 is formed on the surface of the rectangular plate 2. An auxiliary mechanism 5 is arranged inside the groove 4. A push plate 6 is fixedly connected to the surface of the auxiliary mechanism 5, and the surface of the push plate 6 contacts the inner wall of the groove 4. Moving mechanisms 7 are arranged on both sides of the surface of the rectangular plate 2. A double-acting screw 10 is rotatably passed through the top of the moving mechanism 7. An adjusting plate 11 is arranged inside the moving mechanism 7. The adjusting plate 11 is threaded onto the surface of the double-acting screw 10. There are four adjusting plates 11. The four adjustment plates 11 are respectively fixedly connected to the surfaces of the protective frame 13 and the storage frame 14. The bottom of the protective frame 13 is in contact with the top of the storage frame 14. The bottom of the inner wall of the storage frame 14 is equipped with a spraying mechanism 15. Limiting grooves are opened at the top of the storage frame 14 and the bottom of the protective frame 13. The inner wall of the limiting groove is slidably connected to the guide plate 16. The top and bottom of the guide plate 16 are fixedly connected to the limiting plate 17. The surface of the limiting plate 17 is in contact with the inner wall of the limiting groove. By setting the limiting plate 17, the movement of the protective frame 13 and the storage frame 14 can be limited. The guide plate 16 can increase the stability of the storage frame 14 and the protective frame 13 when they move.
[0023] The auxiliary mechanism 5 includes a smooth rod 51, an auxiliary block 52, and a compression spring 53. The smooth rod 51 slides through the surface of the arc frame 1. The surface of the auxiliary block 52 contacts the inner wall of the slide groove 4. The push plate 6 is fixedly connected to the surface of the auxiliary block 52. The compression spring 53 is sleeved on the surface of the smooth rod 51. The two ends of the compression spring 53 are fixedly connected to the inner wall of the arc frame 1 and the surface of the auxiliary block 52, respectively. Vertical plates 12 are fixedly connected to the top and bottom of the auxiliary block 52. The surface of the vertical plate 12 contacts the inner wall of the U-shaped plate 3. The vertical plate 12 facilitates the movement of the auxiliary block 52 by the operator. The U-shaped plate 3 guides the movement of the vertical plate 12 and increases the stability of the connection between the arc frame 1 and the rectangular plate 2.
[0024] The moving mechanism 7 includes a moving frame 71, a force-bearing plate 72, and a tension spring 73. The surface of the moving frame 71 is slidably connected to the surface of the rectangular plate 2. The force-bearing plate 72 is fixedly connected to the surface of the moving frame 71. There are two force-bearing plates 72 and two moving frames 71. The two ends of the tension spring 73 are fixedly connected to the surfaces of the two force-bearing plates 72 respectively. The surface of the force-bearing plate 72 is in contact with the surface of the push plate 6. When the push plate 6 moves, it can push the force-bearing plates 72 on both sides. At this time, the tension spring 73 is stretched under force. Subsequently, the tension spring 73 is stretched under its elastic force. Under the action of the force plate 72, the moving frame 71 can be moved. The surface of the moving frame 71 is fixedly connected with the guide rod 8. The surfaces of both sides of the rectangular plate 2 are provided with guide grooves 9. The surface of the guide rod 8 is in contact with the inner wall of the guide groove 9. The stability of the moving frame 71 during movement can be increased by the cooperation of the guide rod 8 and the guide groove 9. The bidirectional screw 10 rotates through the moving frame 71. The surface of the adjusting plate 11 is slidably connected with the inner wall of the moving frame 71. The surfaces of the protective frame 13 and the storage frame 14 are in contact with the surface of the moving frame 71.
[0025] The spraying mechanism 15 includes a delivery tube 151, a fixing tube 152, and a nozzle body 153. The delivery tube 151 is embedded inside the storage frame 14. The fixing tube 152 is fixedly inserted through the bottom of the inner wall of the storage frame 14 and is connected to the delivery tube 151. The nozzle body 153 is connected to the top of the fixing tube 152. The operator introduces the pesticide into the delivery tube 151, and then the pesticide can be discharged through the fixing tube 152 to the nozzle body 153. The nozzle body 153 can spray the pesticide onto the back of the crop leaves so that the leaves can better absorb the pesticide.
[0026] Working principle: The operator can first adjust the distance between the storage frame 14 and the protective frame 13 according to the height of the blades hanging down. This process involves the operator rotating the double-acting screw 10, causing the adjusting plate 11 to move, thus moving the protective frame 13 and the storage frame 14. During this process, the guide plate 16 and the limiting plate 17 cooperate to guide and limit the movement of the storage frame 14 and the protective frame 13. The operator then moves the vertical plate 12, causing the auxiliary block 52 to move the guide rod 51 and the push plate 6. The force plate 72 then moves the moving frame 71. At this point, the two protective frames 13 separate, and the two storage frames 14 separate as well. The operator can then... This device can be fitted onto the surface of the crop. When the worker stops moving the vertical plate 12, the auxiliary block 52 drives the push plate 6 to reset under the action of the compression spring 53, and the tension spring 73 drives the force plate 72 to reset. At this time, the two protective frames 13 move to opposite sides, and the two placement frames 14 move to opposite sides. Accordingly, this device is fitted onto the surface of the working leaf. The worker injects the medicine into the fixed pipe 152 through the medicine delivery pipe 151, and the nozzle body 153 can spray the medicine onto the back of the leaf. During this process, the protective frame 13 can shield the medicine to reduce the possibility of the medicine spreading and affecting the worker.
