Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a rotary spraying device for preventing pests and diseases. Background Technology

[0002] In agricultural planting, insecticides are a common means of dealing with pests. When using them, the right pesticide should be selected according to the crop and the pest, and they should be used alternately to avoid resistance. At the same time, the safe interval period should be observed. Currently, when spraying liquid pesticides, spraying equipment is generally used to mix the pesticide with water and then spray it directly onto crops. Compared to liquid pesticides, granular form reduces volatilization and drift, and can also slowly release the active ingredients through a carrier, prolonging the duration of action. At the same time, it reduces the risk of operators directly contacting the liquid pesticide. For soil-dwelling pests or underground diseases that damage crop roots, or scenarios requiring long-term pest control during the crop growth period, the main method of applying granular pesticides is manual spreading, with some plots using small fertilizer spreaders as an auxiliary method. However, manual spreading can easily lead to uneven granule distribution, with more pesticide near the plant and less further away, affecting the pest control effect. While machine spreading is more efficient, it cannot effectively adjust the amount of pesticide applied in a single round. If the amount of pesticide entering the spreading wheel is controlled by the size of the discharge port of the hopper, the chance of clogging will increase due to the narrowing of the discharge port diameter. Utility Model Content

[0003] The purpose of this invention is to provide a rotary spraying device for preventing pests and diseases, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rotary spraying device for preventing pests and diseases includes a frame. A rotating shaft is fixedly connected to the bottom of the frame. Rollers are rotatably connected to both ends of the rotating shaft. A first helical gear is fixedly connected to the middle of the rotating shaft. A first axle seat is fixedly connected to the frame above the first helical gear. A drive shaft is rotatably connected inside the first axle seat. A second helical gear is fixedly connected to the lower end of the drive shaft, and the second helical gear meshes with the first helical gear. A base plate is fixedly connected to the frame above the first axle seat, and an annular ring is fixedly connected to the bottom of the base plate. The shield has a second bearing fixedly connected to its top. The top of the drive shaft is rotatably connected to the second bearing. A material throwing wheel is fixedly connected to the drive shaft located between the first bearing and the second bearing. Several partitions are fixedly connected to the material throwing wheel. A first sleeve is inserted into the drive shaft located above the material throwing wheel. Several lifting plates are fixedly connected to the outside of the first sleeve. A side plate is fixedly connected to the end of the lifting plate away from the first sleeve. A connecting frame is fixedly connected between the side plates. A hopper is fixedly connected to the bottom plate.

[0005] As a further preferred embodiment of this utility model, the bottom plate is provided with a plurality of first discharge ports and is connected to the bottom channel of the hopper, so that the pesticide in the hopper can enter the annular cover through the first discharge ports.

[0006] As a further preferred embodiment of this utility model, the top of the annular cover is provided with a plurality of second discharge ports, which are connected to the corresponding first discharge port channels. When the pesticide in the hopper passes through the first discharge port, it can fall into the storage space composed of the lifting plate and two partitions through the second discharge ports.

[0007] As a further preferred embodiment of this utility model, a central shaft is fixedly connected to the center position of the throwing wheel, and multiple movable through slots are opened circumferentially on the inner side of the throwing wheel. The throwing wheel is inserted into and fixed on the transmission shaft through the central shaft. The central shaft provides conditions for the installation of the throwing wheel and the transmission shaft, and at the same time provides conditions for the connection of the first sleeve and the lifting plate to the throwing wheel. The movable through slots allow the connecting frame to be connected to the side plate.

[0008] As a further preferred embodiment of this utility model, a second sleeve is fixedly connected to the center position of the bottom of the connecting frame. The second sleeve is inserted and connected to the central shaft located below the throwing wheel. The height of multiple lifting plates can be adjusted by the connecting frame and the second sleeve in conjunction with the side plate, thereby adjusting the temporary storage space formed between the lifting plate and the two adjacent partitions. In addition, the amount of pesticide thrown in a single round can be achieved in conjunction with the annular cover.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a first helical gear is provided on the outer side of the rotating shaft, and a transmission shaft is provided inside the first shaft seat. A second helical gear at one end of the transmission shaft meshes with the first helical gear. Thus, when the roller is driven to rotate by the frame, the rotating shaft, the first helical gear, the transmission shaft, and the second helical gear are driven to rotate, thereby driving the throwing wheel to rotate for pesticide spraying. No additional power equipment is required, improving the efficiency of pesticide application. Furthermore, the multiple synchronously adjustable lifting plates on the throwing wheel can adjust the storage volume between the throwing wheel and two adjacent partitions, thereby achieving control of the amount of pesticide sprayed per round. There is no need to adjust the discharge port diameter of the hopper, reducing the probability of discharge blockage. Attached Figure Description

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] like Figures 1-6 As shown, the rotary spraying device for preventing pests and diseases provided by this utility model includes a frame 1, a rotating shaft 2 fixedly connected to the bottom of the frame 1, rollers 3 rotatably connected to both ends of the rotating shaft 2, a first helical gear 4 fixedly connected to the middle of the rotating shaft 2, a first axle seat 5 fixedly connected to the frame 1 above the first helical gear 4, a drive shaft 6 rotatably connected inside the first axle seat 5, a second helical gear 7 fixedly connected to the lower end of the drive shaft 6, and the second helical gear 7 meshing with the first helical gear 4, a base plate 8 fixedly connected to the frame 1 above the first axle seat 5, and an annular cover 9 fixedly connected to the bottom of the base plate 8. A second bearing seat 10 is fixedly connected to the top of the annular cover 9. The top of the drive shaft 6 is rotatably connected to the second bearing seat 10. A throwing wheel 11 is fixedly connected to the drive shaft 6 located between the first bearing seat 5 and the second bearing seat 10. Several partitions 12 are fixedly connected to the throwing wheel 11. A first sleeve 13 is inserted and connected to the drive shaft 6 located above the throwing wheel 11. Several lifting plates 14 are fixedly connected to the outside of the first sleeve 13. A side plate 15 is fixedly connected to the end of the lifting plate 14 away from the first sleeve 13. A connecting frame 16 is fixedly connected between the several side plates 15. A hopper 17 is fixedly connected to the bottom plate 8.

[0014] like Figures 3-4As shown, the bottom plate 8 has several first discharge ports 18 that are connected to the bottom channel of the hopper 17, so that the pesticide in the hopper 17 can enter the annular cover 9 through the first discharge ports 18. The top of the annular cover 9 has several second discharge ports 19 that are connected to the corresponding first discharge ports 18. When the pesticide in the hopper 17 passes through the first discharge port 18, it can fall into the storage space composed of the lifting plate 14 and the two partitions 12 through the second discharge ports 19.

[0015] like Figure 3 , Figures 5-6 As shown, a central shaft 20 is fixedly connected to the center of the throwing wheel 11. Multiple movable slots 21 are opened circumferentially on the inner side of the throwing wheel 11. The throwing wheel 11 is inserted into and fixed on the transmission shaft 6 through the central shaft 20. The central shaft 20 provides the conditions for the installation of the throwing wheel 11 and the transmission shaft 6, and at the same time provides the conditions for the connection of the first sleeve 13 and the lifting plate 14 to the throwing wheel 11. The movable slots 21 can connect the connecting frame 16 and the side plate 15. A second sleeve 22 is fixedly connected to the center of the bottom of the connecting frame 16. The second sleeve 22 is inserted into the central shaft 20 located below the throwing wheel 11. The height of the multiple lifting plates 14 can be adjusted by the connecting frame 16 and the second sleeve 22 in conjunction with the side plate 15, thereby adjusting the temporary storage space formed between the lifting plate 14 and the two adjacent partitions 12, and then, in conjunction with the annular cover 9, realizing the amount of pesticide thrown in a single round.

[0016] It should be noted that this utility model is a rotary spraying device for preventing pests and diseases. Before use, granular pesticides are first loaded into the hopper 17. The hopper 17 provides storage space for the pesticides, ensuring a continuous supply of pesticides during application. After the pesticides are loaded, the pre-installed annular sealing plate between the annular cover 9 and the throwing wheel 11 is removed, allowing the pesticides in the hopper 17 to fall sequentially through the bottom channel via the first discharge port 18 and the second discharge port 19. At this time, when the frame 1 is pushed, the frame 1 drives the bottom roller 3 to roll, and the rotation of the roller 3 synchronously drives the rotating shaft 2 to rotate. The first helical gear 4, fixed in the middle of the rotating shaft 2, rotates together with the rotating shaft 2. When the first helical gear 4 rotates, it drives the second helical gear 7 to rotate, which in turn drives the transmission shaft 6 to rotate. When the transmission shaft 6 rotates, the throwing wheel 11, fixed on the transmission shaft 6, rotates accordingly. The multiple partitions 12 on the throwing wheel 11 rotate synchronously with the throwing wheel 11, so that the pesticide in the temporary storage space formed by the partitions 12 and the lifting plate 14 of the throwing wheel 11 is carried to the edge of the throwing wheel 11 by the centrifugal force generated by the rotation of the throwing wheel 11. Under the action of centrifugal force, it is thrown out of the annular shield 9, so as to achieve uniform spraying of pesticide on crops. If it is necessary to adjust the amount of explosives thrown in a single round, the fixing screw inside the first sleeve 13 can be loosened so that one end of the fixing screw no longer abuts against the drive shaft 6. Then the connecting frame 16 can be manually adjusted. The connecting frame 16 drives the side plate 15 to move. The side plate 15 is fixed to the lifting plate 14, which in turn drives the lifting plate 14 to move up and down along the first sleeve 13. The change in the height of the lifting plate 14 will change the volume of the temporary storage space formed by it and the adjacent partition 12. If the volume increases, the amount of explosives thrown in a single round increases. If the volume decreases, the amount of explosives thrown in a single round decreases. After the adjustment is completed, the fixing screw inside the first sleeve 13 can be tightened again.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
