Description

Technical Field

[0001] This utility model relates to the field of rapeseed processing technology, and in particular to a rapeseed impurity screening machine. Background Technology

[0002] Rapeseed, also known as rapeseed, is the seed of rapeseed, a cruciferous crop. It is one of China's major oil crops and honey crops. Its seeds are one of the main raw materials for oil extraction. When rapeseed is put into production, it may contain impurities due to transportation and other steps. Therefore, rapeseed needs to be screened by an impurity screening device before it is put into production.

[0003] Existing rapeseed impurity screening devices often use magnets to adsorb iron impurities when screening rapeseed. However, after a period of time, the magnets become too heavily coated with iron impurities, causing their magnetic attraction to decrease and affecting the screening effect. This necessitates periodic cleaning of the magnets. However, the magnets become unusable during cleaning, requiring the machine to be shut down to complete the adsorption process, thus reducing work efficiency. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] To address the technical problems existing in the background art, this utility model proposes a rapeseed impurity screening machine. This device can still operate normally while cleaning the magnetic suction component, without the need to stop for cleaning, thereby effectively improving the working efficiency of the device.

[0006] (II) Technical Solution

[0007] This utility model provides a rapeseed impurity screening machine, including a belt conveyor mechanism, a mounting plate and a mounting block. The belt conveyor mechanism is horizontally arranged with two support legs at each end. The mounting plate is located between and connected to the support legs on the same side. The mounting block is connected to the upper end of the mounting plate through a rotating component. The upper end of the mounting block is provided with two sets of magnetic components, which are vertically arranged. Any one of the magnetic components can be rotated to be located above the belt conveyor mechanism.

[0008] Preferably, the magnetic component includes a first motor, a drive shaft, and a magnet. The first motor is connected to the upper end of the mounting block, the drive shaft is rotatably connected to the mounting block via a mounting bracket, one end of the drive shaft is coaxially connected to the output shaft of the first motor, and the magnet is detachably fixedly sleeved on the drive shaft. The magnet can rotate to the top of the belt conveyor mechanism.

[0009] Preferably, the rapeseed impurity screening machine further includes a limiting ring, a first through hole for the drive shaft to pass through on the magnet, a drive block on the outer circumferential surface of the drive shaft, a groove for the drive block to pass through on the inner wall of the first through hole, the drive block being slidably disposed in the groove and slidably connected to the magnet, the limiting ring being coaxially sleeved on the end of the drive shaft near the first motor, the magnet being movable to fit against the limiting ring, and a limiting unit for limiting the magnet being provided at the other end of the drive shaft.

[0010] Preferably, the limiting unit includes a threaded head and a nut. The threaded head is coaxially connected to the other end of the drive shaft, and the nut is threaded onto the threaded head. The nut can be moved to fit against the magnet.

[0011] Preferably, the rotating assembly includes a rotating shaft, which is vertically arranged. One end of the rotating shaft is connected to the upper end of the mounting plate, and the other end of the rotating shaft is connected to the mounting block. The mounting plate is provided with a rotating unit for driving the rotating shaft to rotate.

[0012] Preferably, the rotating unit comprises a rack plate, a gear, a second motor, a threaded rod, and a fixed block. The gear is coaxially connected to the rotating shaft. The rack plate is slidably mounted on the mounting plate and meshes with the gear. The rack plate has a first threaded through hole.

The threaded rod is threadedly connected to the rack plate.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention: after adsorption for a period of time, the device can drive the mounting block to rotate via the rotating component. During the rotation of the mounting block, the magnetic adsorption component on it will rotate, thereby rotating another set of magnetic adsorption components above the belt conveyor mechanism. This moves the components that were originally above the belt conveyor mechanism out of the belt conveyor mechanism, making it easier for workers to clean the iron impurities adsorbed on the magnetic adsorption components. This effectively prevents the adsorption effect from deteriorating due to excessive iron impurities adsorbed on the magnetic adsorption components. Furthermore, the device can continue to operate normally while cleaning the magnetic adsorption components without stopping the machine for cleaning, thus effectively improving the working efficiency of the device.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-3As shown, the present invention proposes a rapeseed impurity screening machine, which includes a belt conveyor mechanism 1, a mounting plate 3, and a mounting block 5. The belt conveyor mechanism 1 is horizontally arranged, and two support legs 2 are respectively provided at both ends. The mounting plate 3 is located between and connected to the support legs 2 on the same side. The mounting block 5 is connected to the upper end of the mounting plate 3 through a rotating component. The upper end of the mounting block 5 is provided with two sets of magnetic suction components, which are vertically arranged. Any one of the magnetic components can be rotated to be located above the belt conveyor mechanism 1.

[0023] In this invention, when the device is needed, rapeseed is placed on the belt conveyor 1 and transported by the belt conveyor 1, so that the rapeseed passes under the magnetic suction component. The magnetic suction component can adsorb iron impurities in the rapeseed passing under it. After adsorption for a period of time, the device can rotate the mounting block 5 by rotating the component. During the rotation of the mounting block 5, the magnetic suction component on it will rotate, thereby rotating another set of magnetic suction components to the top of the belt conveyor 1. This moves the magnetic suction component that was originally located above the belt conveyor 1 out of the belt conveyor 1, making it convenient for workers to clean the iron impurities adsorbed on the magnetic suction component. This effectively prevents the adsorption effect from deteriorating due to excessive iron impurities adsorbed on the magnetic suction component. Furthermore, the device can still operate normally while cleaning the magnetic suction component without stopping the machine for cleaning, thus effectively improving the working efficiency of the device.

[0024] In an optional embodiment, the magnetic assembly includes a first motor 6, a drive shaft 8, and a magnet 10. The first motor 6 is connected to the upper end of the mounting block 5. The drive shaft 8 is rotatably connected to the mounting block 5 via a mounting bracket 7. One end of the drive shaft 8 is coaxially connected to the output shaft of the first motor 6. The magnet 10 is detachably and fixedly mounted on the drive shaft 8. The magnet 10 can rotate above the belt conveyor mechanism 1. The first motor 6 can effectively drive the drive shaft 8 to rotate, which in turn drives the magnet 10 mounted thereon to rotate. Thus, during the rotation, the outer circumference of the magnet 10 can be used to attract rapeseed, effectively preventing the magnet 10 from only attracting rapeseed on one side, thereby improving the attraction effect of the magnet 10. Furthermore, the magnet 10 is detachably mounted from the drive shaft 8, so when cleaning the magnet 10, it can be removed from the drive shaft 8 for cleaning. Since the magnet 10 does not need to be cleaned in a fixed position, the workload of cleaning the magnet 10 can be effectively reduced.

[0025] In an optional embodiment, the rapeseed impurity screening machine further includes a limiting ring 11. The magnet 10 has a first through hole through which the drive shaft 8 passes. The outer circumferential surface of the drive shaft 8 is provided with a drive block 9. The inner wall of the first through hole is provided with a sliding groove through which the drive block 9 passes. The drive block 9 is slidably disposed in the sliding groove and slidably connected to the magnet 10. The limiting ring 11 is coaxially sleeved on one end of the drive shaft 8 near the first motor 6. The magnet 10 can move to fit against the limiting ring 11. The other end of the drive shaft 8 is provided with a limiting unit for limiting the magnet 10. Since the drive block 9 can be slidably disposed in the sliding groove, when the magnet 10 is installed on the drive shaft 8, the magnet 10 fits against the limiting ring 11. After the installation of the magnet 10 is completed through the limiting unit, when the drive shaft 8 rotates, it drives the drive block 9 to rotate. The drive block 9 pushes the inner wall of the sliding groove, thereby pushing the magnet 10 to rotate. The installation of the magnet 10 is very simple, which can effectively improve the work efficiency of the workers when cleaning the magnet 10.

[0026] In an optional embodiment, the limiting unit includes a threaded head 12 and a nut 13. The threaded head 12 is coaxially connected to the other end of the drive shaft 8. The nut 13 is threaded onto the threaded head 12 and can be moved to fit against the magnet 10. When it is necessary to limit the magnet 10, the magnet 10 is slid to fit against the limiting ring 11, and the nut 13 is rotated onto the threaded head 12. By rotating the nut 13, the nut 13 moves on the threaded head 12 and moves to fit against the magnet 10, thereby cooperating with the limiting ring 11 to limit the magnet 10.

[0027] In an optional embodiment, the rotating assembly includes a rotating shaft 4, which is vertically arranged. One end of the rotating shaft 4 is connected to the upper end of the mounting plate 3, and the other end of the rotating shaft 4 is connected to the mounting block 5. The mounting plate 3 is provided with a rotating unit for driving the rotating shaft 4 to rotate. The rotating unit can effectively drive the rotating shaft 4 to rotate, thereby driving the mounting block 5 to rotate.

[0028] In an optional embodiment, the rotating unit comprises a rack plate 14, a gear 15, a second motor 16, a threaded rod 17, and a fixing block 18. The gear 15 is coaxially connected to the rotating shaft 4. The rack plate 14 is slidably mounted on the mounting plate 3 and meshes with the gear 15. The rack plate 14 has a first threaded through hole. The second motor 16 and the fixing block 18 are spaced apart on both sides of the first threaded through hole of the rack plate 14. One end of the threaded rod 17 is coaxially connected to the output shaft of the second motor 16, and the other end of the threaded rod 17 passes through the first threaded through hole and is rotatably connected to the fixing block 18. The threaded rod 17 is threadedly connected to the rack plate 14, and the second motor 16 drives the second motor 17. 6 drives the threaded rod 17 to rotate, and the rotation of the threaded rod 17 drives the rack plate 14 connected to it to move. The movement of the rack plate 14 can effectively drive the gear 15 meshing with it to rotate. The rotation of the gear 15 drives the rotating shaft 4 coaxially connected to it to rotate. Since the threaded rod 17 is threadedly connected to the rack plate 14, when there is no external force driving the threaded rod 17 to rotate, the threaded rod 17 can effectively limit the position of the rack plate 14. Thus, the rack plate 14 can effectively limit the gear 15, thereby limiting the rotating shaft 4. This can effectively improve the stability of the position of the mounting block 5 and the magnet 10 on it.
