Description

Technical Field

[0001] This utility model relates to the field of impurity removal devices, specifically to a raw material impurity removal device for livestock and poultry feed production. Background Technology

[0002] In the production of livestock and poultry feed, various raw materials need to be mixed, including legumes (such as soybeans and peas), cereals (such as corn, sorghum, barley, and oats), and roughage (such as rice bran and wheat bran). Before mixing these raw materials, impurities (such as large stones and iron pieces) need to be removed. This step usually involves screening the raw materials using a screening machine. The screening machine generally includes a vibrating screen plate and a receiving plate fixed below the screen plate. The receiving plate is used to guide the screened raw materials out of the screening machine. The receiving plate is usually fixed at an angle inside the screening machine. Although most of the screened raw materials will come out of the screening machine along the receiving plate, some raw materials may get stuck on the receiving plate due to friction, resulting in waste of raw materials.

[0003] For example, patent CN219560454U discloses a feed raw material impurity removal device. Although this feed raw material impurity removal device can separate feed raw materials multiple times simultaneously, thereby improving screening efficiency, it not only improves production efficiency but also reduces equipment operating costs. However, in actual use, since the receiving plate is fixed below the screen plate, most feed raw materials and small particle impurities can roll along the receiving plate. However, some feed raw materials may stagnate on the receiving plate due to resistance, resulting in waste of raw materials. Therefore, it needs to be improved. Utility Model Content

[0032] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0033] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0034] Please see Figures 1-6 This embodiment of a raw material impurity removal device for livestock and poultry feed production includes a frame, a screening chamber inside the frame, a movable and liftable screen plate inside the screening chamber, the screen plate moving to separate feed raw materials and impurities, a receiving plate inside the screening chamber located below the screen plate, the receiving plate being used to transport the screened feed raw materials, a swingable discharge component opposite to the receiving plate being used to drive the feed raw materials on the receiving plate to swing, the screen plate lifting to drive the receiving plate to vibrate and drive the discharge component to work, and a drive component outside the frame being used to drive the screen plate to lift and move.

[0035] In this embodiment, the bottom end of the frame 100 is provided with a discharge hopper 102, the receiving plate 210 is inclinedly arranged in the screening chamber 103, and the end of the receiving plate 210 extends to the top of the discharge hopper 102. Multiple support legs 101 are provided opposite to each other at the bottom end of the frame 100. The support legs 101 can raise the discharge hopper 102 so that a receiving cylinder can be placed below the discharge hopper 102 to collect the feed raw materials after the initial impurity removal for subsequent processing.

[0036] Specifically, one end of the sieve plate 110 extends out of the screening chamber 103. An inclined screening groove 200 is provided on the upper surface of the sieve plate 110. A storage frame 111 is provided on the screening groove 200 within the screening chamber 103. The storage frame 111 has openings at its upper end and on one side. A liftable partition 610 is provided on one side of the storage frame 111. The lifting of the partition 610 controls the opening on the side of the storage frame 111. When removing impurities from feed materials, the feed materials to be removed are first added to the storage frame 111. Then, the sieve plate 110 is driven to reciprocate through a drive mechanism. While reciprocating, the sieve plate 110 can also... The lifting and lowering of the screen plate 110 causes the feed material inside the screen plate 110 to move and vibrate, thereby promoting the separation of feed material and impurities. After being filtered by the screen plate 110, the feed material falls into the screening chamber 103 and is discharged from the discharge hopper 102 through the receiving plate 210. While the screen plate 110 vibrates, it can also drive the receiving plate 210 to vibrate and promote the operation of the discharge component, so that the feed material that is stuck on the receiving plate 210 due to friction can be discharged better. Then the partition plate 610 is moved up to expose the side opening of the storage frame 111, and the impurities in the screening tank 200 are discharged by the screen plate 110 during the back-and-forth movement.

[0037] The movable and lifting mechanism of the sieve plate 110 allows the feed ingredients and impurities located within the sieve plate 110 to move and vibrate, enabling them to contact the sieve plate 110 better and thus separate.

[0038] In this embodiment, by setting the discharge component, the discharge component can swing on the receiving plate 210 during operation, thereby contacting the feed material that is stuck on the receiving plate 210 due to friction, causing it to move and promoting its discharge from the screening chamber 103. Compared with the existing ones, this embodiment can reduce the feed material stuck on the receiving plate 210 and reduce the waste of feed material.

[0039] The screen plate 110 is adjustable in height, which can drive the receiving plate 210 to vibrate. In conjunction with the discharge component, the feed material stuck on the receiving plate 210 can be discharged better. This process does not require additional drive and the structure is relatively simple.

[0040] Combination Figures 1-4 As shown, in this embodiment, a connecting block is provided opposite to the screening chamber. A guide rod is provided on the connecting block and passes through the screen plate. An arc-shaped groove is provided on the screen plate for the guide rod to pass through and slide. A rotatable first plate is provided on the outside of the frame. A second plate is hinged to one end of the first plate. A third plate is hinged to one end of the second plate. A fourth plate is provided on the screen plate. The third plate is raised and lowered on the fourth plate. The rotation of the first plate is used to drive the screen plate to move back and forth.

[0041] Specifically, a motor 401 is provided on the outer side of the frame 100 via a bracket 400, and the output shaft of the motor 401 is fixedly connected to the other end of the first plate 410;

[0042] In this embodiment, the connecting block 300 is fixedly connected to the side wall of the screening chamber 103. One end of the first plate 410 is hinged to the second plate 420, forming a linkage structure between them. When the output shaft of the motor 401 rotates, it pulls the first plate 410 to make a circular motion. When the first plate 410 rotates away from the screen plate 110, under the guidance of the arc groove 500 and the guide rod 502, the first plate 410 will pull the second plate 420, the third plate 430 and the fourth plate 440 away from the screen plate 110. The first plate 410 moves to one side, which in turn drives the screen plate 110 to move closer to the motor 401. When the first plate 410 continues to rotate, as it rotates towards the screen plate 110, under the guidance of the arc groove 500 and the guide rod 502, the first plate 410 will pull the second plate 420, the third plate 430 and the fourth plate 440 to move closer to the screen plate 110, which in turn drives the screen plate 110 to move away from the motor 401. This process is repeated continuously, causing the screen plate 110 to move back and forth.

[0043] Specifically, a notch is provided on the outer side wall of the frame 100. When the first plate 410 and the second plate 420 rotate, they will be located in the notch, so that the frame 100 will not affect the rotation of the first plate 410 and the second plate 420.

[0044] Combination Figures 1-5 As shown in this embodiment, a connecting strip is also provided in the screening chamber. The connecting strip has multiple protrusions. The screen plate has protruding columns that slide on the connecting strip and the protrusions. The protruding columns slide on the connecting strip and the protrusions to drive the screen plate to rise and fall. A spring is sleeved on the guide rod located above the screen plate. The spring is used to push the protruding columns to fit against the connecting strip and the protrusions.

[0045] Specifically, the protrusion 221 includes two oppositely arranged inclined portions and a horizontal portion connecting the inclined portions. During the reciprocating movement of the screen plate 110, when the protruding column 230 moves from the connecting bar 220 through the inclined portion to the horizontal portion, the protruding column 230 can drive the screen plate 110 to move upward. When the protruding column 230 passes through the horizontal portion and the inclined portion and then passes through the connecting bar 220, the screen plate 110 will move downward under the action of gravity.

[0046] Among them, the spring 503 can push the screen plate 110 to move down, so that the protruding column 230 always fits against the connecting strip 220 and the protruding part 221, so that the screen plate 110 can be raised and lowered. In order to prevent the spring 503 from falling off the guide rod 502, the top end of the guide rod 502 is threaded with a first nut 501. In order to prevent the spring 503 from getting stuck in the arc groove 500 when the screen plate 110 moves, the bottom end of the spring 503 is fitted with a gasket 504, and the bottom end of the spring 503 always fits against the gasket 504.

[0047] In order to prevent the screen plate 110 from affecting the rotation of the first plate 410 and the second plate 420 during the lifting and lowering process, the fourth plate 440 is provided with a vertical groove 441, and the third plate 430 is provided with a connecting shaft 431 that slides in the vertical groove 441. Thus, when the screen plate 110 drives the fourth plate 440 to lift and lower, the connecting shaft 431 can slide in the vertical groove 441.

[0048] Combination Figures 2-7 As shown, in this embodiment, the discharge assembly includes a fixed shaft disposed on the surface of the receiving plate. A swing plate that can swing is disposed on the fixed shaft via a torsion spring. A drive plate is disposed on the swing plate. A guide surface is disposed on the drive plate. The impact column moves down to squeeze the guide surface, thereby driving the swing plate to swing.

[0049] In this embodiment, one end of the fixed shaft 700 passes through the receiving plate, and the torsion spring is located at the lower end of the fixed shaft 700. Under the torsion of the torsion spring, the swing plate 701 can swing around the fixed shaft 700. One end of the swing plate 701 will swing towards the extension plate 240 on one side, thereby impacting the feed material stuck on one side of the receiving plate 210, causing the feed material to move and roll along the surface of the receiving plate 210. When the impact column 241 moves down and contacts the guide surface, the drive plate 702 is pressured by the impact column 241, thereby overcoming the torsion of the torsion spring, causing one end of the swing plate 701 to swing towards the extension plate 240 on the other side, impacting the feed material stuck on one side of the receiving plate 210. Repeating this process can better reduce the amount of feed material stuck on the receiving plate 210.

[0050] Specifically, there is a certain gap between the lower surface of the drive plate 702 and the upper surface of the receiving plate 210, so that the feed raw materials are not easily accumulated on the receiving plate 210 when rolling.

[0051] Combination Figures 1-6 As shown in this embodiment, the sieve plate is provided with notch grooves corresponding to the partition plate, the partition plate is provided with mounting blocks, the mounting blocks are provided with threaded rods, the storage frame is provided with bending plates, the bending plates are provided with strip grooves for the threaded rods to pass through, and the protruding end of the threaded rods is threadedly connected with a second nut, which is used to fix the threaded rods in the current position.

[0052] In this embodiment, during the reciprocating movement of the sieve plate 110, the feed material in the storage frame 111 and the screening trough 200 will fall from above the sieve plate 110 into the screening chamber 103. Since the screening trough 200 is inclined, large particles of impurities in the feed material will accumulate at the bottom of the screening trough 200 due to gravity, that is, near the partition plate 610. When the partition plate 610 moves upward and falls off the notch 600, the large particles of impurities in the feed material will leak out from the opening on one side of the storage frame 111. When it is necessary to keep the opening on one side of the storage frame 111 in an open state, the threaded rod in the bent plate 620 can be fixed by tightening the second nut, thereby keeping the partition plate 610 above the opening on one side of the storage frame 111.

[0053] In this embodiment, when removing impurities from raw materials, the feed raw materials to be removed are first added into the storage frame 111. Then, the drive unit drives the screen plate 110 to move back and forth. While moving back and forth, the screen plate 110 can also be raised and lowered, thereby causing the raw materials in the screen plate 110 to move and vibrate, thus promoting the separation of feed raw materials and impurities. After being filtered by the screen plate 110, the feed raw materials fall into the screening chamber 103 and are discharged from the discharge hopper 102 through the receiving plate 210. While the screen plate 110 vibrates, it can also drive the receiving plate 210 to vibrate and promote the operation of the discharge component, so that the feed raw materials that are stuck on the receiving plate 210 due to friction can be discharged better. Then, the partition plate 610 is moved up to discharge the impurities in the feed raw materials from the screening tank 200.

[0054] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
