Description

Technical Field

[0001] The utility model relates to the technical field of straw impurity removal, in particular to a straw magnetic separation impurity removal device. Background Technique

[0002] Straw is the general term for the stems, leaves and ears of mature crops, usually referring to the remaining parts of other crops such as wheat, rice, corn, potatoes, rapeseed, etc. after harvesting the seeds. Usually, a harvester is used to harvest the straw. After harvesting, iron impurities are easily mixed in the straw. Before the straw is prepared for feed processing, it is necessary to clean the iron impurities inside the straw.

[0003] And some devices on the market generally set up a magnetic separation unit. The magnetic separation unit can accurately adsorb the metal impurities inside the straw raw material. The power connection component drives the coil to be energized. At this time, the iron core wound by the coil generates magnetism, so that the iron impurities inside the straw are adsorbed on the outer side surface of the magnetic separation frame. When the end of the power connection component moves out along the groove of the end of the C-shaped frame, the coil is powered off. At this time, the magnetism generated by the iron core wound by the coil decreases or even disappears, which is convenient for cleaning the iron impurities adsorbed outside the magnetic separation frame, achieving the purpose that the magnetic separation frame can continuously remove impurities magnetically, and facilitating the subsequent preparation of feed for the straw raw material.

[0004] However, in the actual use process of the above-mentioned device, when there is too much material, the metal debris will be mixed with the material, which will cause the metal impurities to clamp the material on the outer surface of the magnetic separation frame, resulting in the magnetic separation frame being unable to effectively screen and remove the metal debris in the material. In view of this, we propose a straw magnetic separation impurity removal device. Content of the Utility Model

[0009] Striking member, on the outer surface of the rotating disk, there is a striking member fixedly connected. The striking member is arranged in the shape of a special-shaped block and is composed of an arc-shaped rod and an arc-shaped plate. At the bottom of the striking member away from the rotating disk, there is a counterweight fixedly connected.

[0010] Preferably, the position of the striking member is at the bottom of the transfer plate, and the size of the striking member is adapted to the size of the counterweight, which can enable the striking member to reset well.

[0011] Preferably, the size of the convex block is adapted to the size of the rotating disk, and the arc-shaped surface provided at one end of the convex block is in contact with the external teeth provided on the outer surface of the large gear, which can enable the large gear to strike the convex block well.

[0012] Preferably, the transfer plate is arranged above the conveying plate, and the bottom of the transfer plate is in contact with the upper surface of the limiting plate, which can enable the limiting plate to limit the transfer plate.

[0015] Compared with the prior art, the present utility model provides a straw magnetic separation and impurity removal device, which has the following

[0016] Beneficial effects:

[0017] 1. For this straw magnetic separation and impurity removal device, in order to avoid that when there is too much material, metal impurities cannot be well screened out, the permanent magnet roller rotates to drive the large gear fixedly connected to the rotating shaft to rotate together. This enables the external teeth of the large gear to strike the convex block, thereby causing the rotating disk to rotate, enabling the striking member to strike the bottom of the transfer plate. At the same time, the counterweight fixedly connected to the bottom of the striking member enables the striking member to reset after contacting the transfer plate, allowing the convex block to contact the large gear again. In this way, the materials on the upper surface of the transfer plate can be well shaken loose, and then pass through the conveying plate and contact the outer surface of the permanent magnet roller, enabling the permanent magnet roller to better adsorb iron substances in the materials.

[0018] 2. To prevent materials and metal debris from directly falling onto the upper surface of the shunt member from the upper surface of the transfer plate, when the transfer plate is struck, the materials near the end on the upper surface of the transfer plate will fly up slightly. Where the flying materials contact the inner wall of the baffle, the inner wall of the baffle is arc-shaped. This allows the flying materials to better fall onto the upper surface of the conveying plate when contacting the inside of the baffle. Moreover, the flying materials will fall onto the upper surface of the guiding plate through the gap between the transfer plate and the baffle. The guiding plate is inclined, which can prevent the materials from directly falling onto the upper surface of the shunt member. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] As Figures 1 - 5 shown, the present utility model provides a technical solution: a straw magnetic separation and impurity removal device, including a box body 1. The upper surface of the box body 1 is provided with a feed inlet 2, the bottom of the box body 1 is provided with an impurity discharge port 3, the bottom of the box body 1 is provided with a discharge port 4, one side of the box body 1 is provided with an iron discharge port 5, one side inside the box body 1 is fixedly connected with a conveying plate 8, one side inside the box body 1 is rotatably connected with a permanent magnet roller 9, one side of the box body 1 is fixedly connected with a cleaning brush 10, one side inside the box body 1 is fixedly connected with a shunt member 11, one side of the box body 1 is fixedly connected with a filter plate 12, one side of the box body 1 is fixedly connected with a guiding plate 13, and a dispersion device is arranged inside one side of the box body 1. The dispersion device includes a transfer plate 6, a limiting plate 7, a large gear 14, a rotating disk 15, a convex block 16, a striking member 17 and a counterweight 18.

[0026] In an embodiment of the present utility model, a transfer plate 6 is hinged to one side of the inner wall of the box body 1 near the feed port 2. The transfer plate 6 is arranged above the conveying plate 8, and the bottom of the transfer plate 6 is in contact with the upper surface of the limiting plate 7, which can enable the limiting plate 7 to limit the transfer plate 6. A limiting plate 7 is fixedly connected to one side of the inner wall of the box body 1. A large gear 14 is fixedly connected to the outer surface of the rotating shaft of the permanent magnet roller 9. A rotating disk 15 is rotatably connected to one side of the inner wall of the box body 1. A convex block 16 is fixedly connected to the outer surface of the rotating disk 15 near the large gear 14. One end of the convex block 16 is arc-shaped, and the size of the convex block 16 is adapted to the size of the rotating disk 15. The arc-shaped surface provided at one end of the convex block 16 is in contact with the external teeth provided on the outer surface of the large gear 14, which can enable the large gear 14 to strike the convex block 16 well.

[0027] Meanwhile, a striking member 17 is fixedly connected to the outer surface of the rotating disk 15. The striking member 17 is arranged in the shape of a special-shaped block and is composed of an arc-shaped rod and an arc-shaped plate. The position of the striking member 17 is at the bottom of the transfer plate 6, and the size of the striking member 17 is adapted to the size of the counterweight 18, which can enable the striking member 17 to reset well. A counterweight 18 is fixedly connected to the bottom of the striking member 17 away from the rotating disk 15. After the striking member 17 strikes the bottom of the transfer plate 6, it can reset after contacting the transfer plate 6. A blocking member 19 is fixedly connected to one side of the inner wall of the box body 1. One end of the transfer plate 6 is sleeved inside the blocking member 19, and the inner wall of the blocking member 19 is arc-shaped. When the transfer plate 6 is struck, the material near the end of the upper surface of the transfer plate 6 will fly up slightly. The flying material contacts the inner wall of the blocking member 10, which can enable the flying material to fall better on the upper surface of the conveying plate 8 when contacting the inside of the blocking member 10. A guiding plate 20 is fixedly connected to the bottom of the blocking member 19. The guiding plate 20 is inclined, so that the flying material can fall on the upper surface of the guiding plate 20 through the gap between the transfer plate 6 and the blocking member 19 and be transmitted to the upper surface of the conveying plate 8.

[0028] In the present utility model, during use, materials are put into the interior of the box body 1 from the feed inlet 2. When the materials pass through the transfer plate 6, the permanent magnet roller 9 rotates, causing the large gear 14 fixedly connected to the rotating shaft to rotate together. This makes the external teeth of the large gear 14 strike the convex block 16, thereby causing the rotating disk 15 to rotate, and enabling the striking member 17 to strike the bottom of the transfer plate 6. At the same time, the counterweight 18 fixedly connected to the bottom of the striking member 17 causes the striking member 17 to reset after contacting the transfer plate 6, allowing the convex block 16 to contact the large gear 14 again. In this way, the materials on the upper surface of the transfer plate 6 can be well shaken and dispersed, and then come into contact with the outer surface of the permanent magnet roller 9 through the conveying plate 8. This enables the permanent magnet roller 9 to better adsorb iron substances in the materials. After screening, the materials fall to one side of the shunt member 11 and land on the upper surface of the filter plate 12. In this way, the filter plate 12 filters out impurities in the materials, and the impurities can fall well from the impurity discharge port 3. The screened materials fall from the discharge port 4. At the same time, the iron impurities on the outer surface of the permanent magnet roller 9 are cleaned by the cleaning brush 10 and fall to the other side of the shunt member 11, and are discharged from the iron discharge port 5.

[0029] Further, when the transfer plate 6 is struck, the materials near the end on the upper surface of the transfer plate 6 will fly up slightly. The flying materials contact the inner wall of the baffle 10, and the inner wall of the baffle 10 is arc-shaped. This can enable the flying materials to better land on the upper surface of the conveying plate 8 when contacting the inside of the baffle 10. And the flying materials will fall on the upper surface of the guide plate 20 through the gap between the transfer plate 6 and the baffle 19. The guide plate 20 is inclined, which can prevent the materials from directly falling on the upper surface of the shunt member 11 to facilitate the discharge of the materials.

[0030] Generally speaking, the above has described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
