Description

Technical Field

[0001] The utility model relates to the technical field of feed processing equipment, in particular to a feed crusher which can prevent a screen from being blocked. Background Art

[0002] Feed grinders are mainly used to grind roughage into fine materials of expected size. The reason for grinding roughage into fine materials is that fine materials are easy to contact with digestive juices in the stomach of livestock and poultry, which makes livestock and poultry absorb nutrients better. Therefore, the grinding of roughage is an important part of the processing of roughage by feed grinders.

[0003] In the existing feed grinder, during the process of coarse feed being crushed in the crushing space of the feed grinder, the uncrushed coarse feed will be mixed with the crushed fine material. Under the filtering effect of the screen, the fine material will fall out from the holes of the screen, thereby separating the uncrushed coarse feed from the fine material, and finally completing the operation of screening and discharging the crushed coarse feed.

[0004] However, since the size and shape of the roughage are inconsistent, and the position of the roughage in the grinding space of the feed grinder is also random, the roughage will be stuck in the holes of the screen, thereby reducing the screening efficiency of the screen for fine materials. Furthermore, in the process of the roughage being ground into fine materials, the roughage that is not completely ground will also be stuck in the holes of the screen due to its random position in the grinding space, which will also reduce the screening efficiency of the screen for fine materials.

[0005] Secondly, when the holes of the screen need to be cleaned, the screen needs to be manually removed from the feed grinder to clean the holes of the screen, which is inconvenient because the screen is set at the lower end of the grinding space of the feed grinder. Furthermore, since the components have a service life, when the screen is repeatedly taken out of the feed grinder, the components used to install the screen will malfunction due to repeated disassembly, resulting in the screen being unable to be installed back into the feed grinder after being taken out.

[0024] Refer to the attached figure Figure 1 to Figure 2 A feed grinder capable of preventing screen clogging according to a preferred embodiment of the present invention will be described in detail below, wherein the feed grinder capable of preventing screen clogging comprises a device body 10, a crushing component 20 and a screening component 30.

[0025] The device body 10 has a feed channel 102, and further forms an inlet 101 connected to the upper end of the feed channel 102. The inlet 101 is used to put roughage into the feed channel 102, and the feed channel 102 is used to pass roughage. The device body 10 also has a crushing space 103, which is arranged to be connected to the lower end of the feed channel 102, and the crushing space 103 is used to store roughage to be crushed into fine materials of a predetermined size. In other words, the roughage put into the feed channel 102 through the inlet 101 will fall into the crushing space 103.

[0026] The crushing assembly 20 is disposed on the device body 10 , and is used to crush the roughage in the crushing space 103 into fine materials of a predetermined size.

[0027] The screening assembly 30 includes a screening plate 31, a flip driving member 32 and a stopper 33. The device body 10 also has a feed space 104, and the feed space 104 is located below the crushing space 103. The stopper 33 is located on the side wall of the feed space 104. The screening plate 31 is arranged on the device body 10 and located at the lower end of the crushing space 103. The screening plate 31 is used to carry the roughage stored in the crushing space 103 to be crushed into fine materials of a predetermined size. The flip driving member 32 is arranged on the device body 10. The screening plate 31 is connected to the output end of the flip driving member 32 in a manner that it can hit the stopper 33. The screening plate 31 has a plurality of screening holes 3101 of a predetermined size to connect the crushing space 103 and the feeding space 104 , and the roughage in the crushing space 103 that is crushed by the crushing assembly 20 and contains fine particles of a predetermined size is filtered into the feeding space 104 through the screening holes 3101 .

[0028] The device body 10 includes a fine material bottom plate 11, which is arranged on the device body 10 and located at the lower end of the feed space 104. The fine material bottom plate 11 has a plurality of fine material through holes 1101 of a predetermined size connected to the feed space 104. One end of the fine material through hole 1101 away from the feed space 104 is connected to a channel, so that after the roughage containing fine materials of a predetermined size filtered into the feed space 104 through the screening material through hole 3101 falls on the surface of the fine material bottom plate 11, the fine materials of the predetermined size falling on the fine material bottom plate 11 will pass through the fine material through hole 1101 and be transmitted to the outside of the device body 10 through the channel, and finally the purpose of collecting the roughage crushed into fine materials of a predetermined size is completed.

[0029] Preferably, the flip driving member 32 is implemented to include a motor.

[0030] It should be noted that, in the process of the roughage in the crushing space 103 being crushed into fine particles of a predetermined size by the crushing component 20, the roughage will be scattered under the crushing of the crushing component 20. At this time, the roughage that is not completely crushed will be stuck in the sieve through hole 3101 due to the random changes in its position and shape, so that the sieve through hole 3101 is blocked, and finally the filtering effect of the sieve through hole 3101 is affected. In addition, the roughage in the crushing space 103 will also be stuck in the sieve through hole 3101 due to the random changes in its position and shape, and the filtering effect of the sieve through hole 3101 is affected.

[0031] Those skilled in the art can understand that, when the flip driving member 32 is started, the flip driving member 32 will cause the screen plate 31 to rotate around one side connected to the output end of the flip driving member 32 as an axis, and cause the other side of the screen plate 31 away from the flip driving member 32 to hit the blocking member 33. At this time, the screen plate 31 will vibrate due to inertia, and the roughage stuck in the screen hole 3101 will become loose due to the vibration and its own gravity. After the other side of the screen plate 31 hits the blocking member 33 several times, the roughage stuck in the screen hole 3101 will fall off from the screen hole 3101 into the feed space 104 due to the vibration and its own gravity, thereby finally achieving the purpose of cleaning the screen hole 3101 of the screen plate 31.

[0032] Furthermore, after the roughage in the screening hole 3101 is cleaned out, the screening plate 31 can be returned to its initial position before rotation by controlling the flip drive member 32, so that the screening plate 31 can carry the roughage to be crushed into fine particles of a predetermined size stored in the crushing space 103.

[0033] It should be noted that, during the operation of the feed grinder that can prevent the screen from being blocked, the crushing assembly 20 will generate vibration when crushing the roughage to be crushed into fine materials of a predetermined size in the crushing space 103. The screen plate 31 will rotate around one side connected to the output end of the flip drive member 32 under the vibration, resulting in a gap between the screen plate 31 and the side wall of the crushing space 103. At this time, the incompletely crushed roughage located in the crushing space 103 will fall into the feed transfer space 104 from the gap due to gravity.

[0034] Preferably, the screening material assembly 30 further includes a fixing member 34, which is arranged on the side wall of the material crushing space 103 in a manner that the screening material plate 31 is fixed away from the edge of the flip driving member 32. The fixing member 34 is used to prevent a gap from being generated between the screening material plate 31 and the side wall of the material crushing space 103 due to vibration.

[0035] In this embodiment, preferably, the screen plate 31 is made of metal.

[0036] Preferably, the fixing element 34 is implemented to include an electromagnet.

[0037] Those skilled in the art can understand that, when the screen plate 31 returns to its initial position under the control of the flip drive member 32, the fixing member 34 will suck the edge of the screen plate 31 away from the flip drive member 32 to prevent the screen plate 31 from rotating around a side connected to the output end of the flip drive member 32 due to vibration.

[0038] Specifically, the crushing assembly 20 includes at least one crushing driving member 21, at least one crushing connecting rod 22 and a plurality of crushing members 23. The crushing driving member 21 is disposed on the device body 10, and the output end of the crushing member 23 is disposed toward the crushing space 103. The crushing connecting rod 22 is rotatably disposed at the output end of the crushing driving member 21. A plurality of crushing members 23 are evenly mounted on the crushing connecting rod 22.

[0039] Preferably, the chip driving member 21 is implemented to include a motor.

[0040] It should be noted that, due to the gap between the crushing member 23 and the screening plate 31, the incompletely crushed roughage between the crushing member 23 and the screening plate 31 cannot be crushed by the crushing member 23 because it cannot contact the crushing member 23. Therefore, in order to crush the incompletely crushed roughage between the crushing member 23 and the screening plate 31 by the crushing member 23, the screening through hole 3101 of the screening plate 31 is set to a predetermined size, so that the incompletely crushed roughage between the crushing member 23 and the screening plate 31 and the predetermined size of fine materials pass through the screening through hole 3101 and fall into the feed transfer space 104, and the predetermined size of fine materials will be filtered by the fine material through hole 1101 of the fine material bottom plate 11 and transmitted from the channel connected to the fine material through hole 1101 to the outside of the device body 10, but the incompletely crushed roughage will be left in the feed transfer space 104.

[0041] Preferably, the feed grinder capable of preventing the screen from being blocked also includes a return component 40, which is used to transport the incompletely crushed roughage in the feed space 104 to the crushing space 103, so that the incompletely crushed roughage is crushed into fine material of a predetermined size by the crushing pieces 23 of the crushing component 20, thereby preventing the incompletely crushed roughage in the feed space 104 from clogging the fine material through hole 1101 due to accumulation, and making full use of the incompletely crushed roughage to save the production cost of fine material of a predetermined size.

[0042] Specifically, the material return assembly 40 includes a material moving component 41 and a material extraction component 42. The material moving component 41 includes at least one material moving driving component 411, at least one material moving connecting rod 412 and at least one spiral material moving component 413. The material moving driving component 411 is installed on the device body 10, the material moving connecting rod 412 is rotatably connected to the output end of the material moving driving component 411, and the spiral material moving component 413 is coaxially arranged on the periphery of the material moving connecting rod 412 in a spiral manner. The material extraction component 42 has a suction inlet and a material outlet. The suction inlet of the material extraction component 42 corresponds to an end of the material moving connecting rod 412 away from the material moving driving component 411, and the material outlet of the material extraction component 42 is arranged on the side wall of the crushing space 103.

[0043] Preferably, the pumping member 42 is implemented to include a suction pump.

[0044] Those skilled in the art can understand that, in the process of the material moving connecting rod 412 being driven to rotate by the material moving driving member 411, the spiral material moving member 413 will move following the rotation of the material moving connecting rod 412, and the incompletely crushed roughage in the feeding space 104 will move to the end of the material moving connecting rod 412 away from the material moving driving member 411, so that the incompletely crushed roughage can be sprayed from the material outlet of the material drawing member 42 to the crushing space 103 and to the crushing member 23 through the suction of the suction inlet of the material drawing member 42, so as to crush the incompletely crushed roughage into fine materials of predetermined size.

[0045] Preferably, the material transfer driving member 411 is implemented to include a motor.

[0046] It should be noted that, in the process of the crushing element 23 crushing the roughage, the roughage will be driven by the crushing element 23 and splashed, and the roughage may fly out of the crushing space 103 to the feeding channel 102 or even fly out of the device body 10 from the feeding port 101 under the drive of the crushing element 23.

[0047] In a preferred embodiment of the present invention, the inner diameter of the crushing space 103 gradually increases from the upper end to the lower end to prevent the roughage in the crushing space 103 from flying out of the device body 10 from the feed inlet 101 driven by the crushing member 23 .

[0048] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
