Technical Field
[0001] This utility model relates to the field of oil suspension pesticide preparation technology, and in particular to a sieving device for preparing oil suspension pesticides. Background Technology
[0002] Suspension concentrates are reagents that disperse solid pesticide active ingredients in water. Suspension concentrates are characterized by small particle diameter, high specific gravity, and high biological activity. They are also safe and environmentally friendly. Suspension concentrates have good dispersibility and spreading properties, high suspension rate, strong adhesion, and resistance to rain washout. Suspension concentrates have good and long-lasting pesticide properties. Suspension concentrates are one of the important pesticide formulations in modern pesticides and have been widely used as water-based pesticides.
[0003] In existing technologies, the preparation of suspension pesticides requires the use of sieving devices. However, existing sieving devices can only sieve particles of relatively fixed coarseness, which cannot meet the user's need to adjust the sieving fineness. The screens need to be replaced, and it is not possible to directly sieve particles of different coarseness on a single sieving device. It is also inconvenient to adjust the coarseness of the sieving device within a certain range according to actual needs, which has certain shortcomings. In view of this, we propose a sieving device for the preparation of oil suspension pesticides. Utility Model Content
[0004] The purpose of this invention is to provide a sieving device for preparing oil suspension pesticides, 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 sieving device for preparing oil suspension pesticides, comprising a sieving box, a feeding assembly provided on the upper surface of the sieving box, a telescopic limiting rod fixedly connected to the bottom wall of the sieving box, a connecting rod movably connected inside the telescopic limiting rod, an inner box fixedly connected to the upper end of the connecting rod, a through groove extending into the upper surface of the inner box, a folded rubber plate fixedly connected to the upper surface of the inner box, and the upper surface of the folded rubber plate fixedly connected to the top wall of the sieving box. Next, a first screen, a second screen, and a third screen are fixedly connected to the inner wall of the inner box. Baffles are fixedly connected to the lower surfaces of the first screen, the second screen, and the third screen. A guide plate is fixedly connected to the left inner wall of the inner box. A fixing plate is fixedly connected to the inner wall of the inner box. A displacement plate is slidably connected to the inner wall of the inner box. A second through groove extending from the lower surface of the displacement plate is opened on the upper surface of the displacement plate. The second through groove is adapted to the fixing plate. A sliding groove extending into the interior is opened on the right surface of the inner box. A drive assembly is provided on the inner box.
[0006] Preferably, the drive assembly includes an electric push rod, which is fixedly connected to the right side surface of the inner box, and the output end of the electric push rod is fixedly connected to a connecting plate.
[0007] Preferably, the connecting plate is slidably connected inside the sliding groove, and the left side surface of the connecting plate is fixedly connected to the displacement plate.
[0008] Preferably, the bottom wall of the sliding groove is provided with a telescopic groove, and a sealing plate is slidably connected to the inner wall of the telescopic groove.
[0009] Preferably, a spring is fixedly connected to the lower surface of the sealing plate, and the end of the spring away from the sealing plate is fixedly connected to the bottom wall of the expansion groove.
[0010] Preferably, the bottom walls of both the inner box and the screening box are provided with a third through groove.
[0011] Preferably, a second baffle is fixedly connected to the inner wall of the third channel on the screening box, and a folded rubber plate is also fixedly connected between the second baffle and the baffle.
[0012] Preferably, a folded rubber plate is also fixedly connected between the bottom wall of the screening box and the lower surface of the inner box, and a vibration motor is fixedly connected to the lower surface of the inner box.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This sieving device for preparing oil suspension pesticides delivers pesticide technical material into the inner chamber via a feeding assembly. After entering, the pesticide technical material falls onto the outer surface of the first screen via a guide plate. After being sieved by the first screen, it falls onto a displacement plate and a fixed plate and slides, thereby discharging the pesticide technical material. When it is necessary to adjust the sieving fineness, the displacement plate is driven synchronously by a drive assembly. After the displacement plate moves, it disengages from the fixed plate, allowing the pesticide technical material to enter through the second channel on the displacement plate and fall onto the upper surface of the second screen, where it can then be sieved. This structure allows for the selection of three sieving modes during pesticide technical material sieving, thereby adjusting the sieving fineness and reducing the time required for adjusting the sieving fineness in traditional structures, thus improving overall production efficiency.
[0015] 2. The screening device for preparing oil suspension pesticides can prevent the sealing between the inner and outer boxes from decreasing during vibration by setting up a deformable foldable rubber plate. At the same time, it can prevent the material inside the inner box from accidentally flying out of the inner box, which would make it difficult to clean or affect the movement of the inner box, thus improving the overall stability of the device.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Please see Figure 1-4This utility model provides a technical solution: a sieving device for preparing oil suspension pesticides, including a sieving box 1, a feeding assembly on the upper surface of the sieving box 1, a telescopic limiting rod 2 fixedly connected to the bottom wall of the sieving box 1, a connecting rod 3 movably connected inside the telescopic limiting rod 2, an inner box 4 fixedly connected to the upper end of the connecting rod 3, a through groove extending into the upper surface of the inner box 4, a folded rubber plate 5 fixedly connected to the upper surface of the inner box 4, the upper surface of the folded rubber plate 5 fixedly connected to the top wall of the sieving box 1, a first screen 6, a second screen 7, and a third screen 8 fixedly connected to the inner wall of the inner box 4, and a fixed lower surface of each of the first screen 6, second screen 7, and third screen 8 fixedly connected to... A guide plate 10 is fixedly connected to the left inner wall of the inner box 4, and a fixing plate 11 is fixedly connected to the inner wall of the inner box 4. A displacement plate 12 is slidably connected to the inner wall of the inner box 4. A second through groove 13 extending from the lower surface of the upper surface of the displacement plate 12 is provided, and the second through groove 13 is adapted to the fixing plate 11. A sliding groove 14 extending into the inner surface of the inner box 4 is provided on the right surface of the inner box 4. A driving assembly is provided on the inner box 4. The screening holes on the first screen 6, the second screen 7, and the third screen 8 are gradually decreasing in size. The pesticide raw material is transported into the inner box 4 through the feeding assembly. After entering, the pesticide raw material falls onto the outer surface of the first screen 6 through the guide plate 10, and falls into the positioning position after being screened by the first screen 6. The sliding plate 12 slides on the fixed plate 11, thereby discharging the pesticide raw material. This screening device has three modes. In the first mode, the driving component moves the two lower sliding plates 12, causing the fixed plate 11 to enter the second through groove 13 on the sliding plate 12. This forms a complete plate with the fixed plate 11, allowing the pesticide raw material to be directly discharged after being screened by the first screen 6 through the complete plate formed by the sliding plate 12 and the fixed plate 11. In the second mode, the upper sliding plate 12 separates from the fixed plate 11 via the driving component, allowing the pesticide raw material to fall onto the second screen 7 through the second through groove 13 after being screened by the first screen 6. Then, it undergoes a second screening through the second screen 7. At this time, the bottom displacement plate 12 and the fixed plate 11 are still in a fitted state. The pesticide raw material after screening through the second screen 7 will be discharged through the guide of the displacement plate 12 and the fixed plate 11. In the third mode, both displacement plates 12 are separated from the two fixed plates 11, so that the pesticide raw material can be screened through the first screen 6, the second screen 7 and the third screen 8 in sequence, and then discharged. Through the above structure, three screening modes can be selected when screening pesticide raw materials, thereby adjusting the screening fineness, reducing the time required for adjusting the screening fineness in the traditional structure, and improving the overall production efficiency.
[0024] Furthermore, the drive assembly includes an electric push rod 15, which is fixedly connected to the right side surface of the inner box 4. A connecting plate 16 is fixedly connected to the output end of the electric push rod 15. The connecting plate 16 is slidably connected inside the sliding groove 14. The left side surface of the connecting plate 16 is fixedly connected to the displacement plate 12. A telescopic groove 17 is provided on the bottom wall of the sliding groove 14. A sealing plate 18 is slidably connected to the inner wall of the telescopic groove 17. A spring 19 is fixedly connected to the lower surface of the sealing plate 18. The end of the spring 19 away from the sealing plate 18 is fixedly connected to the bottom wall of the telescopic groove 17. A third through groove is provided on the bottom walls of both the inner box 4 and the screening box 1. A second baffle 20 is fixedly connected to the inner wall of the third through groove on the screening box 1. A folded rubber plate 5 is also fixedly connected between the second baffle 20 and the baffle 9. A folded rubber plate 5 is also fixedly connected between the bottom wall of the screening box 1 and the lower surface of the inner box 4. A vibrating motor 21 is fixedly connected. The pesticide raw material enters the inner box 4 through the feeding assembly. When adjusting the screening fineness, the electric push rod 15 drives the displacement plate 12 to move synchronously with the connecting plate 16. When the displacement plate 12 moves, the cooperation of the sealing plate 18 and the spring 19 prevents the pesticide raw material from entering the sliding groove 14. When the vibrating motor 21 drives the inner box 4 to vibrate up and down, the folding rubber plate 5 can provide movement space. Through the above structure, the pesticide raw material can be crushed before entering the inner box 4 for screening, thereby avoiding the problem of large particles causing the first screen 6 to be unable to screen, thus improving the quality after screening. The metering wheel 23 and the metering groove 24 can be used to avoid the problem of too much pesticide raw material entering at one time, which would reduce the screening efficiency. The vibrating motor 21 mentioned in the text is an existing structure, specifically model PT-MVE15\3M-2.
[0025] Working principle: The pesticide raw material is conveyed into the inner box 4 through the feeding component. After entering, the pesticide raw material falls onto the outer surface of the first screen 6 through the guide plate 10. After being screened by the first screen 6, it falls onto the displacement plate 12 and the fixed plate 11 and slides, thereby discharging the pesticide raw material. This screening device has three modes. In the first mode, the driving component drives the two lower displacement plates 12 to move, so that the fixed plate 11 enters the second through groove 13 on the displacement plate 12, thereby forming a complete plate with the displacement plate 12 and the fixed plate 11. This allows the pesticide raw material to be directly discharged through the complete plate formed by the displacement plate 12 and the fixed plate 11 after being screened by the first screen 6. In the second mode, the upper displacement plate 12 is separated from the fixed plate 11 by the driving component, so that the pesticide raw material can pass through the first screen 6 after being screened by the first screen 6. The second channel 13 falls onto the second screen 7, and then undergoes secondary screening again through the second screen 7. At this time, the lowest displacement plate 12 and the fixed plate 11 are still in a fitted state. The pesticide raw material after being screened by the second screen 7 will be discharged through the guide of the displacement plate 12 and the fixed plate 11. In the third mode, both displacement plates 12 are separated from the two fixed plates 11, so that the pesticide raw material can be screened through the first screen 6, the second screen 7 and the third screen 8 in sequence, and then discharged. When adjusting the screening fineness, the electric push rod 15 is used to drive the displacement plate 12 to move synchronously with the connecting plate 16. When the displacement plate 12 moves, the cooperation of the sealing plate 18 and the spring 19 prevents the pesticide raw material from entering the interior of the sliding groove 14. When the vibration motor 21 drives the inner box 4 to vibrate up and down, the folding rubber plate 5 can provide movement space.
[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
