Description

Technical Field

[0001] This application relates to the technical field of grain processing, and in particular to a peanut impurity removal device and its usage method. Background Art

[0002] Before grain collection and processing, it is first necessary to remove impurities in the grain. For example, before peanut processing, it is necessary to remove peanut shells, dust, and small stones in peanut grains to improve the subsequent processing quality of peanut grains. Currently, a specific gravity stone-removing machine is generally used for peanut grain impurity removal.

[0003] Currently, a patent document with the authorization announcement number CN207446745U discloses a specific gravity stone-removing machine, which includes a machine case. An inlet air suction device, a storage hopper, an air suction hood, a stone-removing screen mesh, and a transmission mechanism with a weight sleeve installed on the main drive shaft are arranged inside the machine case. When the specific gravity stone-removing machine works, by utilizing the differences in specific gravity and suspension speed between grains and associated stones and with the assistance of the upward airflow, heavy impurities such as associated stones sink to the bottom layer, and through the eccentric transmission mechanism, the rotational movement of the main shaft is transformed into the reciprocating movement of the stone-removing screen plate installed on the screen body, moving towards the stone discharge end, while the grains floating on the upper layer flow towards the discharge end under the action of their own weight, thereby separating the stones and impurities in the grains.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: During the screening process of peanut grains, the machine case is in a vibrating state, resulting in the storage hopper also being in a vibrating state, and further causing it difficult for peanut grains to be loaded into the storage hopper.

Subsequently, the transfer hopper is driven by the first driving member to slide, and the transfer hopper is lifted to a certain height. The peanut grains in the transfer hopper enter the storage hopper through the bellows pipe, completing the feeding operation of the peanut grains. The operation is simple and convenient; at the same time, the feeding efficiency and effect of the peanut grains are improved; further, under the action of the storage cover, the transfer hopper is stored in the storage cover.

A semi-circular ring is arranged at the end of the shielding cloth, and the semi-circular ring is fixedly arranged on the bellows pipe.

[0014] By adopting the above technical solution, during the lifting and lowering process of the transfer hopper, the shielding cloth is driven to move, and the shielding cloth shields the long strip-shaped notch to relatively partition the storage cover, further reducing the possibility of impurities in the storage cover escaping through the long strip-shaped notch; the shielding cloth is fixedly connected to the bellows pipe through the semi-circular ring, reducing the gap between the bellows pipe and the shielding cloth, and further reducing the possibility of impurities escaping.

[0016] By adopting the above technical solution, under the action of the guide rails, the shielding cloth is crimped below the guide rails, reducing the possibility of the shielding cloth separating from the side wall of the storage cover.

[0017] Optionally, a volute spring is provided on the side wall of the storage cover. One end of the volute spring is provided on the winding shaft, and the other side is provided on the side wall of the storage cover.

[0018] By adopting the above technical solution, under the action of the volute spring, it is convenient to drive the winding shaft to rotate to wind the shielding cloth, so that the shielding cloth is wound in the storage cover in an orderly manner; at the same time, the influence of the shielding cloth on the lifting of the transfer hopper is reduced, and at the same time, the possibility of the shielding cloth being damaged is also reduced.

When the pouring of the peanut grains is completed, the transfer hopper 6 is driven to lift and lower by the first driving member. After the transfer hopper 6 is lifted to a certain height, the peanut grains in the transfer hopper 6 enter the storage hopper 2 through the accordion tube 7, and then enter the chassis 1 to complete the impurity removal operation.

[0048] Refer to Figure 2 and Figure 3 To reduce the possibility of light impurities floating during the pouring of peanut grains, a storage cover 8 is fixedly arranged on the base 5, the storage cover 8 houses the transfer hopper 6, a long strip-shaped notch 9 is opened on any side plate of the storage cover 8, and the accordion tube 7 passes through the long strip-shaped notch 9; under the action of the storage cover 8, the transfer hopper 6 is housed in the storage cover 8, and the light impurities are relatively isolated in the storage cover 8, reducing the impact of the light impurities on the staff.

[0049] Refer to Figure 3 and Figure 4, in the embodiment of the present application, a plurality of guide rails 10 are fixedly arranged on the base 5. There are four guide rails 10, which are arranged in a rectangular shape on the base 5. Further, a chute 11 is formed on the guide rail 10. The length direction of the chute 11 is parallel to the length direction of the guide rail 10. A sliding block 12 is provided on the side wall of the conical hopper 61. The sliding block 12 is slidably clamped in the chute 11. The length direction of the guide rail 10 is perpendicular to the plane where the base 5 is located.

When the transfer hopper 6 reaches a certain height, the peanut grains in the transfer hopper 6 enter the storage hopper 2 through the bellows pipe 7, completing the feeding operation of the peanut grains.

[0050] Referring to Figure 1 , to further reduce the possibility of impurities escaping, an air suction pipe 15 is arranged on the chassis 1. The air suction pipe 15 is communicated with the chassis 1. A dust suction pipe 16 is arranged on the top of the storage cover 8. The dust suction pipe 16 is communicated with the air suction pipe 15. The light impurities generated in the storage cover 8 enter the air suction pipe 15 through the dust suction pipe 16 and are discharged to a suitable place through the air suction pipe 15.

[0051] Referring to Figure 4 and Figure 5 , to reduce the possibility of light impurities escaping through the long strip-shaped notch 9, a winding shaft 17 is rotatably arranged on the side wall of the storage cover 8 where the long strip-shaped notch 9 is opened. The winding shaft 17 is located inside the storage cover 8. There are two winding shafts 17. The two winding shafts 17 are respectively located on both sides of the bellows pipe 7 and are arranged vertically. The length direction and the rotation axis of the winding shaft 17 are both perpendicular to the length direction of the long strip-shaped notch 9. Combining Figure 6 and Figure 7 , a shielding cloth 18 is wound on the winding shaft 17. A semi-circular ring 19 is arranged at the end of the shielding cloth 18. The semi-circular rings 19 on both sides are spliced into a complete ring. The semi-circular ring 19 is fixedly arranged on the bellows pipe 7. The ring is sleeved on the bellows pipe 7. During the lifting and lowering process of the bellows pipe 7, the ring drives the shielding cloth 18 on one side to wind and the shielding cloth 18 on the other side to unwind, so that the shielding cloth 18 closes the long strip-shaped notch 9 in real time, thereby reducing the possibility of light impurities escaping through the long strip-shaped notch 9.

[0052] Combining Figure 6 and Figure 7, To facilitate the winding of the shielding cloth 18, a volute spring 20 is provided on the side wall of the storage cover 8. One end of the volute spring 20 is arranged on the winding shaft 17, and the other side is arranged on the side wall of the storage cover 8; under the action of the elastic force of the volute spring 20, the winding shaft 17 is driven to rotate, and the winding shaft 17 rotates to wind the released shielding cloth 18, so that the shielding cloth 18 is wound on the winding shaft 17 in an orderly manner.

[0053] Refer to Figure 5 and Figure 7 , To reduce the possibility of the shielding cloth 18 separating from the side wall of the storage cover 8, two guide rails 21 are fixedly arranged on the side wall of the storage cover 8 where the long strip-shaped notch 9 is opened. The length direction of the guide rails 21 is parallel to the length direction of the long strip-shaped notch 9, and the length of the guide rails 21 is greater than the length of the long strip-shaped notch 9. The two guide rails 21 are respectively located on both sides of the long strip-shaped notch 9, and the two winding shafts 17 are located at both ends of the guide rails 21. Both sides of the shielding cloth 18 are crimped under the guide rails 21; the shielding cloth 18 slides under the guide rails 21, and the shielding cloth 18 is crimped under the guide rails 21, so that the shielding cloth 18 fits on the side wall of the storage cover 8, improving the closing effect of the shielding cloth 18 on the long strip-shaped notch 9.

[0054] Refer to Figure 5 and Figure 7 , Further, to facilitate the sliding of the shielding cloth 18 under the guide rails 21, a plurality of rollers 22 are rotatably arranged on the surface of the guide rails 21 facing the shielding cloth 18. The rotation axis of the rollers 22 is parallel to the length direction of the winding shaft 17, and the rollers 22 are crimped on the surface of the shielding cloth 18; under the action of the rollers 22, the shielding cloth 18 is crimped under the rollers 22. On the one hand, the possibility of the shielding cloth 18 separating from the side wall of the storage cover 8 is reduced, and on the other hand, it is convenient for the shielding cloth 18 to slide on the side wall of the storage cover 8, and then it is convenient for the bellows tube 7 to lift in the long strip-shaped notch 9.

[0055] Refer to Figure 2 , To facilitate the transfer of peanut grains into the transfer hopper 6, one side wall of the storage cover 8 is rotatably arranged on the storage cover 8.

[0056] Refer to Figure 3, in the embodiment of the present application, a plurality of air inlet pipes 23 are provided on the side wall of the transfer hopper 6. The air inlet pipes 23 are arranged around the inner wall of the transfer hopper 6, and are arranged on the conical hopper 61 and the cylindrical barrel 62, and are evenly arranged on the conical hopper 61 and the cylindrical barrel 62. An air pump 25 is arranged in the receiving cover 8. A collecting air pipe 24 is connected to all the air inlet pipes 23, and the other end of the collecting air pipe 24 is arranged at the air outlet end of the air pump 25; during the process of pouring the peanut grains, the air pump 25 is started. The air pump 25 extracts external air into the collecting air pipe 24 and the air inlet pipes 23, and ejects through the air inlet pipes 23. The ejected air separates the light impurities in the peanut grains. The separated light impurities enter the air inlet pipes 23 through the dust suction pipe 16 and are discharged; on the other hand, under the action of the ejected air, the peanut grains are in a suspended state, and the peanut grains are turned over in the transfer hopper 6, so that the peanut grains are initially separated from the stones, and the peanut grains and the stones are stratified. The stones are located below the peanut grains, and then the impurity removal operation is carried out in the chassis 1.

[0057] Referring to Figure 3 , further, in order to reduce the possibility of peanut grains impacting out of the transfer hopper 6, an end cover 26 is rotatably arranged at the opening of the conical hopper 61. A plurality of air outlet holes 27 are opened on the end cover 26. The rotation axis of the end cover 26 is parallel to the length direction of the winding shaft 17. The rotation of the end cover 26 closes the opening of the conical hopper 61, thereby reducing the possibility of peanut grains falling.

[0058] The implementation principle of a peanut impurity removal device in an embodiment of the present application is as follows:

[0059] When removing impurities from peanut grains, first, rotate the side wall of the receiving cover 8 to open the feeding port of the receiving cover 8. Then rotate the end cover 26 to open the conical hopper 61, and then start the air pump 25. The air pump 25 extracts air into the collecting air pipe 24 and ejects it from the air inlet pipes 23. Then pour the peanut grains into the conical hopper 61. During the process of the peanut grains entering the conical hopper 61, the ejected air removes the light impurities in the peanut grains; again, rotate the end cover 26 to close the conical hopper 61;

[0060] The air pushes the peanut grains and the stones to roll in the conical hopper 61 and impacts on the end cover 26, so as to realize the preliminary stratification of the peanut grains and the stones;

[0061] Then start the winch 13. The winch 13 lifts the conical hopper 61 to a certain height. The peanut grains in the conical hopper 61 and the cylindrical barrel 62 enter the storage hopper 2 through the bellows pipe 7, completing the feeding operation of the peanut grains.
