Technical Field

[0001] The utility model relates to the field of feed processing equipment, in particular to a feed raw material feeding device. Background Art

[0002] When using corn as raw material to process feed, after the corn is harvested, a threshing machine is needed to thresh the corn cobs to obtain the required corn kernels. During the threshing process, large debris such as corn stalks and iron impurities are easily mixed into the corn raw materials. At the same time, during threshing, some corn kernels will be broken under the collision of the machine, resulting in some broken corn kernels in the finally obtained corn kernels. Eventually, the corn raw materials are in a state of mixed large and fine impurities.

[0003] When processing corn as feed, it is necessary to classify the raw materials and control the target raw materials to enter the storage bin according to the situation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, in combination with the embodiments of the present invention, the technical solutions of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0024] A feed raw material feeding device, as Figures 1-7 shown, includes a primary cleaning bin 1. In this embodiment, the structure of the primary cleaning bin 1 can screen and separate corn raw materials, thereby forming three materials with different thicknesses, that is, the bottom of the primary cleaning bin 1 is provided with three outlets including a large impurity hopper 4, a raw material hopper 5, and a fine impurity hopper 6. The primary cleaning bin 1 divides the corn raw materials into large particle impurities, corn raw materials, and finely crushed impurities. The large particle impurities are simply called large impurities, and after being separated, they fall into the large impurity hopper 4; similarly, the corn raw materials fall into the raw material hopper 5 after being separated, and the finely crushed corn is separated and enters the fine impurity hopper 6.

[0025] Furthermore, as Figure 1 shown, the lower part of the primary cleaning bin 1 is supported by a frame body 2 to form a pipeline layout space 3. The lower end of the large impurity hopper 4 is connected with a large impurity outlet pipe 7. The frame body 2 can support the primary cleaning bin 1 to form a larger space at its lower part and is used for arranging the feeding pipeline. Specifically, a large impurity outlet pipe 7 is connected below the large impurity hopper 4, and the larger particle impurities led out by it cannot be used and can be directly sent out and discarded.

[0026] A raw material pipe 8 is connected below the raw material hopper 5. The raw material pipe 8 is finally connected to the raw material bin for feed production. A three-way pipe 9 is connected below the fine impurity hopper 6. The inlet side 10 of the three-way pipe 9 is connected to the fine impurity hopper 6, the first side outlet 11 is connected to the first fine impurity shunt pipe 13, and the second side outlet 12 is connected to the second fine impurity shunt pipe 14; the first fine impurity shunt pipe 13 is connected to the raw material pipe 8. An iron impurity separator 15 is provided at the lower end of the raw material pipe 8. The lower end of the raw material pipe 8 is connected to the raw material bin. A control valve 16 is provided at the three-way pipe 9, as Figures 5-7 shown; in actual use, according to the quality of the separated raw materials, if the separated fine impurities contain more parasites and cannot be used, the separated fine impurities are discarded; if the separated fine impurities are relatively clean, without parasites and are detected to meet the use standards, the second side outlet 12 can be closed through the control valve 16, as Figure 6 shown, so that the fine impurities flow into the raw material pipe 8, thereby reusing the fine impurities.

[0027] Specifically, as Figure 5As shown, the control valve 16 includes a valve housing 30, a valve flap 31, and a valve shaft 32. The inner wall of the valve housing 30 is cylindrical. The valve flap 31 is in the shape of a tile. The valve shaft 32 is rotatably connected at the axis of the valve housing 30. The valve shaft 32 is connected to the valve flap 31 through a plurality of connecting rods 33. The valve shaft 32 controls the rotation of the valve flap 16 of the valve around the valve shaft 32. The outer wall of the valve flap 31 is arranged close to the inner wall of the valve housing 30. The end of the valve shaft 32 extends out of the valve housing 30 and is connected to the driving part. The driving part controls the rotation of the valve shaft 16 of the valve. Through the connecting rod 33, the valve flap 16 of the valve is controlled to rotate in the valve housing 30. Since the valve flap 31 fits on the inner wall of the valve housing 30, the corresponding outlets of the valve 16 can be controlled to be closed during rotation, such as Figure 5 The schematic diagram shows the state where the valve flap 31 can simultaneously close the first side outlet 11 and the second side outlet 12; such as Figure 6 The schematic diagram shows that the valve flap 31 closes the second side outlet 12, so that the inlet side 10 is communicated with the first side outlet 11, so that the fine impurities enter the first fine impurity shunt pipe 13. Similarly, the valve flap 31 can also close the first side outlet 11, so that the fine impurities flow out through the second fine impurity shunt pipe 14; in actual use, when fine impurities are generated, first control the second side outlet 12 to open, so that the fine impurities flow out and are sent for inspection. If it meets the use standard, the valve flap 31 can be moved to Figure 6 The position shown in the figure controls the fine impurities to enter the raw material pipe 8. It can also be like Figure 7 As shown in the figure, the control valve 16 flap closes the inlet side 10. This control valve 16 is relatively flexible to use.

[0028] Such as Figure 1 As shown in the figure, it can be understood that after the corn raw materials in the raw material pipe 8 pass through the iron impurity separator 15, the unseparated iron impurities entrained in the corn raw materials can be magnetically separated. Such as Figure 3 As shown in the figure, the iron impurity separator 15 includes an inner cylinder 17, an outer cylinder 18, and a plug valve 19. The upper and lower ends of the inner cylinder 17 are connected to the raw material pipe 8. The outer cylinder 18 is arranged in a surrounding manner outside the outer cylinder 18. There is a certain distance between the outer cylinder 18 and the inner cylinder 17, so as to facilitate the permanent magnet 21 to be arranged on the inner wall of the outer cylinder 18. The magnetic field of the permanent magnet 21 passes through the inner cylinder 17, so that the iron impurities in the material passing through the inner cylinder 17 can be attracted to the inner wall of the inner cylinder 17; the inner cylinder 17 is made of non-ferromagnetic material; so that the magnetic field of the permanent magnet 21 can pass through the inner cylinder 17. In actual use, according to needs, the inner cylinder 17 can be made of any one of copper, aluminum, plastic, austenitic stainless steel or glass.

[0029] Such as Figure 2 、 3As shown, a clean-out door 20 that can be opened is provided on one side of the outer cylinder body 18. The inner cylinder body 17 is disassembled or installed through the clean-out door 20. Slide gate valves 19 are arranged at the upper and lower ends of the outer cylinder body 18 to close the raw material pipe 8. During actual use, when it is necessary to clean the iron impurities on the inner wall of the inner cylinder body 17 after using for a period of time, the slide gate valves 19 on the upper and lower sides are closed, and the clean-out door 20 is opened, so that the inner cylinder body 17 can be removed, and then the impurities inside it can be cleaned up.

[0030] Specifically, as Figure 3 , 4 shown, the inner wall of the inner cylinder body 17 includes an upper connection end 22, a middle diameter-expanded part 23, and a lower connection end 24. The diameters of the upper connection end 22 and the lower connection end 24 match that of the raw material pipe 8. Hoop rings 27 are provided at the upper and lower ends of the outer cylinder body 18. The hoop ring 27 includes a fixed ring 28 and a hinged ring 29. The fixed ring 28 and the hinged ring 29 are connected to form a circular ring and are tightened around the connection part of the inner cylinder body 17 and the raw material pipe 8. The hinged ring 29 is arranged at the upper and lower ends of the clean-out door 20, and the hinged ring 29 is controlled by the clean-out door 20 to rotate to open or close. One side of the clean-out door 20 is hinged, and the other side can be connected in the form of a buckle 34. By opening the buckle 34, the clean-out door 20 can be opened. At the same time, hinged rings 29 are also arranged above and below the clean-out door 20. Thus, when the clean-out door 20 is opened, the inner cylinder body 17 is also released from fixation, so that the upper and lower ends of the inner cylinder body 17 can be separated from the raw material pipe 8. On the contrary, during installation, the inner cylinder body 17 is placed into the outer cylinder body 18 through the clean-out door 20, then the clean-out door 20 is closed, and the buckle 34 is locked, so that the hinged ring 29 and the fixed ring 28 form a hoop ring 27 to tightly seal the gap where the inner cylinder body 17 is connected to the raw material pipe 8.

[0031] Furthermore, as Figure 3 shown, the diameter of the middle diameter-expanded part 23 is larger than that of the upper connection end 22 or the lower connection end 24, so that an enlarged annular cavity 25 is formed on the inner wall of the inner cylinder body 17. A diversion inclined surface 26 is provided on the inner wall of the upper connection end 22, and the falling raw materials are diverted to the middle of the inner cylinder body 17 through the diversion inclined surface 26. As Figure 3 shown by the dotted line in, during the corn raw material blanking process, the upper diversion inclined surface 26 causes the corn to converge towards the middle. Under the action of magnetic force, the iron impurities mixed in the raw materials are attracted to the inner wall of the enlarged annular cavity 25. Thus, during the corn blanking process, the impact of the falling materials on the iron impurities can be reduced, and it is effectively avoided that the adsorbed iron impurities fall into the lower raw material pipe 8.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
