Description

Technical Field

[0001] This invention belongs to the field of seed pretreatment technology, and specifically relates to a wheat seed pretreatment device. Background Technology

[0002] In wheat cultivation, wheat seeds are usually treated with pesticides before planting. By mixing the seeds with pesticides, the wheat seeds are coated with a special pesticide, which helps them resist pests and diseases and improves their growth.

[0003] However, existing wheat seeds contain many impurities that cannot be separated from the seeds. As a result, the impurities come into contact with the solution during the soaking process, which can affect the soaking of the seeds. At the same time, the wet seeds after soaking also increase the difficulty of separating them from the impurities. Therefore, a pretreatment device that can remove residue during the soaking process is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a wheat seed pretreatment device to solve the problems existing in the prior art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A wheat seed pretreatment device includes a mixing cylinder, a feed hopper mounted on the upper end of the mixing cylinder, an outer cylinder fixedly mounted on the tail end of the mixing cylinder, a support leg fixedly mounted on the lower end of the outer cylinder, a rotating plate sealed and rotatably mounted on the side of the outer cylinder near the feed hopper and the mixing cylinder, a drive assembly mounted around the rotating plate for rotating the rotating plate, an arc-shaped plate fixedly mounted on the rotating plate and sealed and rotatably connected to the mixing cylinder, horizontal plates abutting and sealingly sealing the two ends of the arc-shaped plate with the outer cylinder, a drain pipe mounted on the lower end of the outer cylinder, several drainage holes located inside the outer cylinder opened on the periphery of the mixing cylinder, an electrically operated discharge pipe mounted on the tail end of the mixing cylinder, a slag removal mechanism connected to the outer cylinder mounted on the side of the outer cylinder, and a conveying paddle mounted inside the mixing cylinder.

[0006] The slag removal mechanism includes a slag removal box connected to the outer cylinder. The upper part of the slag removal box is inclined on the side away from the outer cylinder. A filter screen is installed inclined inside the slag removal box. A sealing plate is slidably connected to the lower part of the slag removal box. An up-and-down lifting assembly is installed at the lower end of the sealing plate. Several water pipes connected to the outer cylinder are installed on the outer side of the bottom of the slag removal box. An electric slag discharge pipe is installed in the slag removal box.

[0007] The lifting assembly includes a sealing sliding rod fixedly installed at the lower end of the sealing plate. The sealing sliding rod is fixedly connected to a connecting rod. The support leg is rotatably mounted with a turntable that is driven and connected to the output end of the brake motor. An eccentric column is eccentrically fixedly installed on the turntable. A limiting frame that is slidably connected to the support leg is sleeved on the eccentric column. An L-shaped rod that is fixedly connected to the connecting rod is fixedly installed at the lower end of the limiting frame.

[0008] The drive assembly includes a drive motor fixedly mounted to the support leg, and the output end of the drive motor is connected to a drive gear rotatably mounted to the support leg. A gear set is mounted on the periphery of the rotating plate and meshes with the drive gear.

[0009] The filter screen is fixedly installed with a limiting rod that is rotatably installed with the slag removal box. The limiting rod extends out of the slag removal box and is fixedly installed with a locking component. The locking component includes a rotating rod that is fixedly connected to the limiting rod. The rotating rod is fixedly connected to the slag removal box through a threaded rod. The size of the filter screen matches the vertical line between the inclined surface of the slag removal box and the limiting rod.

[0010] The discharge pipe is equipped with an internally threaded pipe at its end, and the internally threaded pipe is threadedly connected to a threaded ring, which is then fixedly fitted with a metal bellows.

[0011] This invention can simultaneously and automatically remove impurities from the solution during the soaking process, avoiding the secondary contamination problems of traditional static soaking, ensuring the cleanliness of the solution, and thus improving the soaking quality of the seeds. At the same time, the circulating solution can more evenly contact each seed, shortening the soaking time and improving processing efficiency compared to static soaking.

[0012] By rotating the filter screen, trapped impurities can be quickly removed, making cleaning and maintenance very convenient, saving time and effort. The added metal corrugated tube design allows for precise control of the discharge point, such as extending directly into the packaging bag, avoiding spillage and cross-contamination, and greatly improving operational convenience.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Example 1: As Figure 1-6 As shown, a wheat seed pretreatment device of the present invention includes a mixing cylinder 1, a feeding hopper 11 installed at the upper end of the mixing cylinder 1, an outer cylinder 12 fixedly installed at the tail end of the mixing cylinder 1, a support leg 13 fixedly installed at the lower end of the outer cylinder 12, a rotating plate 14 jointly and rotatably installed on the side of the outer cylinder 12 near the feeding hopper 1, a drive assembly installed around the rotating plate 14 for rotating the rotating plate 14, an arc-shaped plate 15 fixedly installed on the rotating plate 14 and rotatably connected to the mixing cylinder 1, horizontal plates 35 abutting and sealingly connected at both ends of the arc-shaped plate 15 to the outer cylinder 12, a drain pipe 16 installed at the lower end of the outer cylinder 12, a plurality of drainage holes 17 located inside the outer cylinder 12 are opened around the mixing cylinder 1, an electrically operated discharge pipe 18 is installed at the tail end of the mixing cylinder 1, a slag removal mechanism connected to the outer cylinder 12 is installed on the side of the outer cylinder 12, and a conveying paddle 19 is installed inside the mixing cylinder 1.

[0018] The slag removal mechanism includes a slag removal box 20 connected to the outer cylinder 21. The upper part of the slag removal box 20 is inclined on the side away from the outer cylinder 12. A filter screen 21 is installed inclined inside the slag removal box 20. A sealing plate 22 is slidably connected to the lower part of the slag removal box 20. An up-and-down lifting component is installed at the lower end of the sealing plate 22. Several water pipes 23 connected to the outer cylinder 12 are installed on the outer side of the bottom of the slag removal box 20. An electric slag discharge pipe 24 is installed in the slag removal box 20.

[0019] The lifting assembly includes a sealing sliding rod 25 fixedly installed at the lower end of the sealing plate 22. The sealing sliding rod 25 is fixedly connected to a connecting rod 26. The support leg 13 is rotatably mounted with a turntable 27 that is driven by the output end of the brake motor 33. An eccentric column 28 is eccentrically fixedly installed on the turntable 27. The eccentric column 28 is fitted with a limiting frame 29 that is slidably connected to the support leg 13. An L-shaped rod 30 is fixedly installed at the lower end of the limiting frame 29 and fixedly connected to the connecting rod 26.

[0020] The drive assembly includes a drive motor 31 fixedly mounted to the support leg 13. The output end of the drive motor 31 is connected to a drive gear 32 rotatably mounted to the support leg 13. A gear set 34 is mounted on the periphery of the rotating plate 14 and meshes with the drive gear 32.

[0021] The filter screen 21 is fixedly installed with a limiting rod 40 that is rotatably installed with the slag removal box 20. The limiting rod 40 extends out of the slag removal box 20 and is fixedly installed with a locking component. The locking component includes a rotating rod 41 that is fixedly connected to the limiting rod 40. The rotating rod 41 is fixedly connected to the slag removal box 20 through a threaded rod 42. The size of the filter screen 21 matches the inclined surface of the slag removal box 20 and the vertical line of the limiting rod 40.

[0022] When using, put the wheat seeds that need to be pretreated into the mixing drum 1, and then put in the mixing agent or soaking solution into the mixing drum 1 to soak the wheat seeds in the solution. When seeds need to be soaked for a longer period of time, the arc-shaped plate 15 is first sealed at the bottom of the mixing drum 1, thereby blocking the inlet of the slag removal box 20. Then, the solution is added into the mixing drum 1, filling it halfway. At this point, the seeds are added into the mixing drum 1. Simultaneously, the existing technology drives the conveyor paddle 19 to rotate and transport the seeds to the end. When the contact agent is activated, the lifting and lowering components and the drive components can be started. The drive components drive the rotating plate 14, the arc-shaped plate 15, and the horizontal plate 35 to rotate. During the rotation of the horizontal plate, the solution accumulated at the bottom of the outer drum 12 is directed to the slag removal box 20. The movement causes the solution to enter the slag removal box for slag removal. Then, the slag-removed solution is transported to the top of the outer cylinder 12 by the up and down lifting components. At this time, the arc plate 15 is located at the bottom of the mixing cylinder 1, so the slag-removed solution will enter the bottom of the mixing cylinder 1 through the drain hole 17 and enter to contact and absorb with the seeds. When the arc plate 15 rotates again, it will enter the bottom of the outer cylinder 12, and then push the solution into the slag removal box 20 again for slag removal. This can prevent impurities inside the seeds from mixing inside the seeds. This cyclic slag removal can remove impurities inside the seeds and also soak the seeds. After the solution enters the slag removal box 20, the solution passes through the inclined filter screen 21 to block impurities, and then flows into the bottom of the inclined slag removal box 20. At this time, the sealing plate 22 is located below the filter screen 21, and the inclined surface of the slag removal box 20 is exposed. In this way, the solution can flow into the bottom after filtration. Moreover, the upper side of the sealing plate 22 is inclined to facilitate the solution to remain. Then, during the downward movement of the sealing plate 22, the lower part of the slag removal box 20 that can be sealed with the sealing plate 22 is squeezed into the water pipe 23. Then, the solution enters the mixing drum 1 from the upper side of the outer cylinder 12 through the drain hole 17. At the same time, a one-way inlet valve can be installed at the connection between the water pipe 23 and the slag removal box 20 so that the solution can only enter the water pipe 23 from the slag removal box 20. Moreover, the capacity of the sealing connection between the slag removal box 20 and the sealing plate 22 is greater than the capacity of all the connecting pipes 23. Thus, a single downward movement of the sealing plate 22 can allow the solution to re-enter the mixing drum 1. When slag discharge is required, the threaded rod 42 is disengaged from the slag removal box 20, which then drives the filter screen 21 to rotate inside the slag removal box 20. The filter screen 21 rotates downward and remains vertical, allowing impurities to fall through the filter screen 21 and be discharged with the help of water flow. When filtration is required, the end of the filter screen 21 is brought into contact with the inclined surface of the slag removal box 20 to block and filter the solution. Finally, the filter screen 21 is fixed by threading the threaded rod 42 to the rotating rod 41 and the limiting rod 40.

[0023] This invention can remove impurities inside seeds during the pretreatment soaking process using a slag removal mechanism. It can also improve the soaking effect and efficiency by using a flowing aqueous solution.

[0024] Example 2: A further improvement on Example 1, an internally threaded pipe 43 is installed at the end of the discharge pipe 18. The internally threaded pipe 43 is threadedly connected to a threaded ring 44, and a metal corrugated pipe 45 is fixedly installed on the threaded ring 44. After soaking is completed, the electric discharge pipe is opened to output the seeds outward through the conveying paddle 19. At the same time, the metal corrugated pipe 45 can be threaded at the end of the discharge pipe 18 to control the position of the output end of the metal corrugated pipe 45, thereby controlling the position of the seed discharge. For example, when bagging, the metal corrugated pipe can be directly inserted into the bag for operation, which is more convenient and faster.
