[0002] Feed refers to products processed and manufactured by light industry for animal use, and plays a vital role in animal breeding. In order to improve the digestion and absorption rate of animals, and to facilitate subsequent processing steps such as transportation, mixing, and granulation, and to improve production efficiency and quality assurance, feed needs to be crushed.

[0003] In the prior art, a feed crusher has been published, with the document number CN221619579U, which includes a support base, a chassis at the top of the support base, a filling hopper at the bottom of the chassis, a dividing mechanism, a crushing mechanism and a filter plate arranged in sequence from top to bottom in the chassis, and an adjustment mechanism at the bottom of the filter plate. The crushing mechanism includes two crushing rollers arranged in the chassis, and the two crushing rollers are meshed with each other, and the two crushing rollers realize the crushing of the feed.

[0004] However, in the above scheme, the feed is only crushed once by the crushing roller, and the crushing effect is relatively limited. In addition, the uncrushed or crushed feed with relatively large particles will fall directly onto the filter net. Although the adjustment structure can drive the filter plate to move up and down to filter the feed, the large particles of feed will block the filter plate over time, thereby affecting the discharge of the feed.

[0028] See Figures 1 to 5 As shown, a raw material crusher for feed production includes a bracket 1, a chassis 2 is arranged on the bracket 1, a discharge port 3 is arranged below the chassis 2, and the discharge port 3 is in a normally closed state. A side opening 4 is provided on the chassis 2, and a feed pipe 5 is connected to the side opening 4. A fan 6 is also provided outside the chassis 2, and the air inlet of the fan 6 is connected to the chassis 2. The fan 6 can generate negative pressure in the chassis 2. A crushing device and a filtering device are also provided in the chassis 2. The filtering device covers the crushing device, and a dredging device is provided above the filtering device. When the above-mentioned feed raw material crusher is used, the fan 6 is started to generate negative pressure inside the chassis 2, thereby sucking the feed raw materials into the chassis 2, and the crushing device is started. The crushing device crushes the feed raw materials, and the crushed feed raw materials accumulate in the chassis 2 through the filtering device. During this process, the dredging device can dredge the filtering device, and finally the discharge port 3 is opened to discharge the crushed feed out of the chassis 2.

[0029] The crushing device includes a crushing roller, which has two crushing rollers, namely a main roller 7 and a driven roller 8. The two crushing rollers are both horizontal and mesh with each other. Two connecting plates are provided on the inner wall of the chassis 2, namely a first connecting plate 9 and a second connecting plate 10, wherein the center of the first connecting plate 9 is connected to a driving motor 11, and the driving motor 11 is located on a support plate 12 outside the chassis 2, and the second connecting plate 10 is fixedly connected to the inner wall of the chassis 2. The two connecting plates are symmetrically distributed about the central axis of the chassis 2. A first annular slide groove 13 is provided on the first connecting plate 9, and a groove 14 is provided at the center of the second connecting plate 10. One end of the driven roller 8 is adapted in the first slide groove 13, and the other end of the driven roller 8 is fixedly connected to the second connecting plate 10. One end of the main roller 7 is fixedly connected to the center of the first connecting plate 9, and the other end of the main roller 7 is adapted in the groove 14 on the second connecting plate 10. A through hole 15 is also provided on the second connecting plate 10, and the above-mentioned side opening 4 is communicated with the through hole 15 on the second connecting plate 10;

[0030] When the feed material enters the chassis 2 through the side opening 4, the driving motor 11 is in operation to control the first connecting plate 9 to rotate, thereby driving the main roller 7 to rotate. The feed is crushed into fine particles by the two crushing rollers.

[0031] Since there may be a situation where the crushing is not in place, a filtering device is provided in the chassis 2, and the filtering device includes a mesh cylinder 16. The cross-section of the mesh cylinder 16 is square. Both ends of the mesh cylinder 16 are connected to two connecting plates. One end of the mesh cylinder 16 is fixedly connected to the first connecting plate 9, and the other end of the mesh cylinder 16 is slidably connected to the second connecting plate 10. Specifically, a second chute 17 is provided on the second connecting plate 10, and the second chute 17 is also annular. The other end of the mesh cylinder 16 is adapted to be in the second chute 17. When the drive motor 11 is working, the mesh cylinder 16 rotates with the first connecting plate 9, and the other end of the mesh cylinder 16 can rotate in the second chute 17;

[0032] When the net drum 16 rotates, the large particles of feed material in the net drum 16 are turned over under the action of centrifugal force, and the large particles of feed can be crushed for the second time, which enhances the crushing effect of the device to a certain extent.

[0033] A dredging device is also provided in the chassis 2, which is connected to the inner top wall of the chassis 2. The dredging device is located directly above the mesh tube 16. The dredging device includes a top hanging plate 18, which is connected to the inner top wall of the chassis 2 through a telescopic rod 19. Several dredging arms 20 are provided on the lower surface of the top hanging plate 18; a through hole is provided on the inner top wall of the chassis 2, which vertically penetrates the inner top wall of the chassis 2. An electric push rod 21 is provided at the through hole, and the telescopic end of the electric push rod 21 is fixedly connected to the center of the top hanging plate 18. When the electric push rod 21 is extended or retracted, the vertical movement of the dredging arm 20 can be controlled. In the initial state, the electric push rod 21 is in a retracted state.

[0034] After the device has been working for a period of time, the crushed materials in the chassis 2 need to be discharged. At this time, the device stops feeding and the drive motor 11 stops working. One side of the mesh cylinder 16 is parallel to the dredging device, and the dredging device is moved downward. The dredging arm 20 corresponds to the mesh on the mesh cylinder 16. The dredging arm 20 can dredge the mesh cylinder 16 and poke large-particle feed into the mesh cylinder 16. When the device works again, the crushing device will crush these large-particle feed raw materials again.

[0035] In addition, a guide plate 22 is provided in the chassis 2, and a high-mesh filter plate is also provided on the chassis 2. The filter plate is located at the junction of the air inlet of the fan 6 and the chassis 2. The setting of the guide plate 22 and the filter plate can prevent the feed raw materials from blocking the air inlet of the fan 6 when feeding into the chassis 2.

[0036] As another embodiment of the present invention, the cross-section of the above-mentioned mesh cylinder is circular, and the dredging device still includes a top hanging plate 18, which is connected to the inner top wall of the chassis 2 through a vertical arm 23. The top hanging plate 18 is located directly above the crushing device, and the lower surface of the top hanging plate 18 is provided with bristles 24, which are in contact with the surface of the mesh cylinder 16. When the mesh cylinder 16 rotates, the bristles 24 will push the large particles of feed blocked on the mesh of the mesh cylinder 16 back into the interior of the mesh cylinder 16. Since the top hanging plate 18 is located directly above the crushing device, the large particles that are pushed off are crushed again by the crushing device, thereby enhancing the crushing effect of the device on the feed.

[0037] When using the above-mentioned feed raw material crusher, first place the feed pipe 5 into the feed raw material storage bin, start the fan 6 to generate negative pressure inside the chassis 2, so as to suck the feed raw materials into the chassis 2, and then start the drive motor 11, the crushing device starts to work, the main roller 7 starts to rotate, and the feed raw materials are crushed under the cooperation of the main roller 7 and the driven roller 8. At the same time, the mesh drum 16 also rotates, and the large particles of feed raw materials in the mesh drum 16 are turned over under the action of centrifugal force, and the large particles of feed can be crushed for the second time. After the device has worked for a period of time, the discharge port 3 is opened to discharge the crushed feed raw materials in the chassis 2, and at the same time, the drive motor 11 is turned off, the top surface of the mesh drum 16 is parallel to the top hanging plate 18, so that the electric push rod 21 is extended, and the dredging arm 20 dredges the mesh drum 16; when all the feed in the chassis 2 is discharged, the discharge port 3 is closed, and the above steps are repeated for the device.

[0038] The driving motor 11 uses a low-power stepping motor of an existing product, and only applies its function without improving its structure.

[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based primarily on the scope of protection of the claims.
