Description

Technical Field

[0001] This invention relates to the field of feed processing technology, specifically to a raw material crushing device for feed production with anti-clogging function. Background Technology

[0002] During the breeding process, various feeds are needed for feeding. The feed is generally composed of four parts: protein feed, energy feed, roughage and additives. Usually, crop straw, fish meal and rice bran need to be fully crushed and then mixed thoroughly. Existing feed ingredient crushing devices typically have filters installed inside the device for filtering the crushed feed ingredients. However, during the crushing process, there may be large-sized materials that can clog the filters, resulting in low filtration efficiency and affecting the normal operation of the crushing device. Summary of the Invention

[0003] The purpose of this invention is to provide a feed production raw material crushing device with anti-clogging function to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A feed production raw material crushing device with anti-clogging function includes a machine body. The top of the machine body has several feed inlets, and the bottom of the machine body has a discharge outlet. A crushing component is installed inside the machine body. The crushing component consists of a cone and a filter screen. The filter screen is located outside the cone and is rotatably connected to the cone and the filter screen. The filter screen is rotatably connected to the machine body. The cone is used to crush feed raw materials, and the filter screen is used to filter the crushed feed raw materials. A driver is installed at the bottom of the crushing component to drive the crushing component.

[0005] After the driver starts the crushing assembly, the raw material is fed into the machine body through the feed port. The raw material first enters the cone body and is crushed in the cone body. Then the crushed raw material is conveyed to the filter screen through the cone body. The filter screen then filters the crushed raw material. The unfiltered raw material will return to the cone body for further crushing under the action of the filter screen, so that the crushed size of the raw material finally meets the crushing range.

[0006] Preferably, the cone-shaped body is composed of three conical arc plates and a support column, with a gap between two adjacent conical arc plates. The outer wall of the conical arc plate is provided with an outer breaking plate, and the inner wall of the conical arc plate is provided with an inner breaking plate.

[0007] The three conical arc plates move continuously toward the support column and the filter screen, causing the distance between two adjacent conical arc plates to change continuously. This allows the crushed raw material to move through the gap between two adjacent conical arc plates, and the crushed raw material is transported from the cone to the filter screen. During the movement of the conical arc plates, the conical arc plates drive the inner crushing plate and the outer crushing plate to rotate in a spiral.

[0008] Preferably, the support column is located in the middle of the three conical arc plates. A movable ring and a fixed ring are provided on the inner wall of the support column. The movable ring is located above the fixed ring. The movable ring is hinged to the top of the three conical arc plates respectively through a hinge rod. The movable ring and the support column are driven by a thread. The fixed ring is hinged to the bottom of the three conical arc plates respectively through a hinge rod.

[0009] As the moving ring reciprocates along the support column, it drives the hinge rod at the top of the conical arc plate to move. Since the fixed ring is fixedly connected to the support column, when the moving ring rotates, it uses the fixed ring as a fulcrum, causing the conical arc plate to rotate around the rotation axis of the fixed ring and the hinge rod. Consequently, the conical arc plate reciprocates between the support column and the filter screen, causing the distance between two adjacent conical arc plates to continuously change. During the rotation, the conical arc plate drives the inner crushing plate and the vertical plate to shear and crush the raw material inside the cone, while the outer crushing plate and the first spiral plate grind and crush the raw material between the cone and the filter screen, thereby improving the efficiency of raw material crushing.

[0010] Preferably, a plurality of vertical plates are provided on the side of the moving ring near the fixed ring, and the plurality of vertical plates are arranged around the axis of the moving ring. A cutting tool is provided on the side of the vertical plate near the conical arc plate.

[0011] During the spiral rotation of the moving ring and the support column, the moving ring reciprocates along the axis of the support column. In turn, the moving ring drives several vertical plates to move vertically in a spiral motion. The vertical plates drive the cutter to move, so that the cutter and the inner crushing plate cooperate to complete the crushing of the raw material.

[0012] Preferably, a screw is provided at the top of the support column, and the screw has a bidirectional thread.

[0013] By setting a bidirectional spiral, the reciprocating motion of the moving ring can be achieved without changing the rotation direction of the drive motor shaft.

[0014] Preferably, the rotation direction of the cone is opposite to the rotation direction of the filter screen.

[0015] Preferably, the bottom of the filter screen is provided with a first rotating ring, which is located outside the fixed ring. The inner wall of the filter screen is provided with a first spiral plate. The top of the filter screen is provided with a conveying groove. A second spiral plate is provided in the conveying groove. The first spiral plate is connected to the second spiral plate. One end of the conveying groove is connected to the space between the filter screen and the cone. The other end of the conveying groove is connected to the space between the cone and the feed inlet.

[0016] The filter screen rotates under the action of the first rotating ring, which in turn drives the first spiral plate to rotate. The first spiral plate, in turn, drives the second spiral plate to rotate within the conveying trough. Unfiltered raw materials in the filter screen move under the action of the rotation of the first spiral plate, causing them to move from the space between the filter screen and the cone towards the side closer to the conveying trough. After the raw materials are conveyed from the first spiral plate to the second spiral plate, they are then conveyed within the conveying trough and from there towards the space between the cone and the feed inlet. This allows the raw materials to re-enter the cone for further crushing, ensuring that the crushed size of the raw materials meets the filtration range of the filter screen.

[0017] Preferably, a plurality of rotating rollers are provided on the inner wall of the machine body, a plurality of protrusions are provided on the side of the rotating rollers away from the machine body, and a plurality of anti-clogging pins are provided on the roller wall of the rotating rollers, the anti-clogging pins being used to clean the clogging of the filter screen.

[0018] During the rotation of the filter screen, some anti-clogging needles extend into the filter screen's pores, causing the rotating roller and the filter screen to mesh. The rotation of the filter screen then drives several rotating rollers, which in turn drive the anti-clogging needles. These needles continuously extend into the filter screen's pores, cleaning the screen and preventing clogging that could affect the filtration of raw materials. Simultaneously, the rotating rollers drive several protrusions to rotate, which continuously impact the outer wall of the filter screen. This vibration is transmitted through the screen to the raw material between the screen and the conical body, further accelerating the filtration efficiency.

[0019] Preferably, both the bump and the anti-blocking pin are made of rubber.

[0020] Rubber bumps and anti-clogging pins effectively protect the filter and prevent it from being damaged.

[0021] Preferably, the driver includes a drive body, a drive motor is disposed within the drive body, a drive gear is disposed on the drive shaft of the drive motor, the drive gear is connected to a support column, a toothed ring is disposed at the bottom of the first rotating ring, a plurality of fixed gears are disposed between the toothed ring and the drive gear, a secondary gear is disposed between the fixed gears and the toothed ring, and the toothed ring meshes with the drive gear for transmission through the secondary gears and the fixed gears.

[0022] The drive shaft of the drive motor drives the drive gear to rotate, and the drive gear drives the support column to rotate during the rotation. At the same time, the drive gear meshes with the fixed gear, causing the fixed gear to rotate under the action of the drive gear. In turn, the fixed gear drives the secondary gear to rotate, which in turn drives the gear ring to rotate. The gear ring drives the first rotating ring to rotate, which in turn drives the filter screen to rotate, thus achieving synchronous and opposite rotation of the cone and the filter screen.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. When the moving ring rotates, the fixed ring acts as a fulcrum, causing the conical arc plate to rotate around the rotation axis of the fixed ring and the hinge rod. Consequently, the conical arc plate reciprocates between the support column and the filter screen, causing the distance between two adjacent conical arc plates to continuously change. During the rotation, the conical arc plate drives the inner crushing plate and the vertical plate to shear and crush the raw material inside the cone, while the outer crushing plate and the first spiral plate grind and crush the raw material between the cone and the filter screen, thereby improving the efficiency of raw material crushing.

[0024] 2. During the rotation of the filter screen, some anti-clogging needles extend into the filter screen's pores, causing the rotating roller and the filter screen to mesh. As the filter screen rotates, it drives several rotating rollers, which in turn drive the anti-clogging needles. These needles continuously extend into the filter screen's pores, cleaning the screen and preventing clogging that could affect the filtration of raw materials. Simultaneously, the rotating rollers drive several protrusions to rotate, which continuously impact the outer wall of the filter screen. This vibration is transmitted through the screen to the raw material between the screen and the cone, further accelerating the filtration efficiency. Attached Figure Description

[0027] Example: Figures 1-8 As shown, the present invention provides a technical solution for a feed production raw material crushing device with anti-clogging function, including a machine body 1.

The plurality of vertical plates 233 are arranged around the axis of the moving ring 231. A cutting tool is provided on the side of the vertical plate 233 near the conical arc plate 211.

[0034] In one specific embodiment of the present invention, a plurality of rotating rollers 27 are provided on the inner wall of the machine body 1, a plurality of protrusions 271 are provided on the side of the rotating rollers 27 away from the machine body 1, and a plurality of anti-clogging pins 272 are provided on the roller wall of the rotating rollers 27, the anti-clogging pins 272 being used to clean the blockage of the filter screen 22.

[0035] In one specific embodiment of the present invention, both the bump 271 and the anti-blocking pin 272 are made of rubber.

[0036] In one specific embodiment of the present invention, the driver 3 includes a driver body 31, a driver motor is disposed inside the driver body 31, a driver gear 32 is disposed on the drive shaft of the driver motor, the driver gear 32 is connected to the support column 23, a toothed ring 33 is disposed at the bottom of the first rotating ring 221, a plurality of fixed gears 34 are disposed between the toothed ring 33 and the driver gear 32, a secondary gear is disposed between the fixed gears 34 and the toothed ring 33, and the toothed ring 33 meshes with the driver gear 32 for transmission through the secondary gears and the fixed gears 34.

[0037] Working principle of the invention: The drive shaft of the drive motor drives the drive gear 32 to rotate, and the drive gear 32 drives the support column 23 to rotate during the rotation. After the driver 3 drives the crushing component 2 to start, the raw material is conveyed into the machine body 1 through the feed port 11. During the rotation of the support column 23, the moving ring 231 is driven by the threaded transmission. First, the raw material enters the conical body 21, causing the moving ring 231 to reciprocate along the axis of the support column 23. During this movement, the moving ring 231 drives several vertical plates 233 to move vertically in a spiral motion, which in turn moves the cutting tool. As the moving ring 231 reciprocates along the support column 23, it drives the hinge rod at the top of the conical arc plate 211 to move. Since the fixed ring 232 is fixedly connected to the support column 23, when the moving ring 231 rotates, it uses the fixed ring 232 as a fulcrum, causing the conical arc plate 211 to rotate around the rotation axis of the fixed ring 232 and the hinge rod. Consequently, the conical arc plate 211 reciprocates between the support column 23 and the filter screen 22, causing the distance between two adjacent conical arc plates 211 to change continuously. During the rotation, the conical arc plate 211 drives the inner crushing plate 213 and the vertical plate 233 to shear and crush the raw material inside the conical body 21, while the outer crushing plate 212 and the first spiral plate 24 grind and crush the raw material between the conical body 21 and the filter screen 22. The three conical arc plates 211 move continuously toward the support column 23 and the filter screen 22, causing the distance between two adjacent conical arc plates 211 to change continuously. This allows the crushed raw material to move through the gap between two adjacent conical arc plates 211, so that the crushed raw material is transported from the conical body 21 to the filter screen 22. During the movement of the conical arc plates 211, the conical arc plates 211 drive the inner crushing plate 213 and the outer crushing plate 212 to rotate in a spiral. While the drive gear 32 rotates, it also meshes with the fixed gear 34, causing the fixed gear 34 to rotate under the action of the drive gear 32. In turn, the fixed gear 34 drives the secondary gear to rotate, which in turn drives the gear ring 33 to rotate. The gear ring 33 then drives the first rotating ring 221 to rotate, which in turn drives the filter screen 22 to rotate, thus achieving synchronous reverse rotation of the cone body 21 and the filter screen 22. The filter screen 22 rotates under the action of the first rotating ring 221, causing the first spiral plate 24 to rotate during the rotation of the filter screen 22. The first spiral plate 24, in turn, causes the second spiral plate 26 to rotate during the rotation of the first spiral plate 24. The second spiral plate 26 rotates within the conveying trough 25. The raw material that has not been filtered in the filter screen 22 will move under the action of the rotation of the first spiral plate 24, causing the raw material to move from the space between the filter screen 22 and the cone 21 towards the side closer to the conveying trough 25. After the raw material is conveyed from the first spiral plate 24 to the second spiral plate 26, the raw material is then conveyed within the conveying trough 25 and from the conveying trough 25 towards the space closer to the cone 21 and the feed inlet 11, so that the raw material re-enters the cone 21 for further crushing, ensuring that the crushed size of the raw material meets the filtration range of the filter screen 22. During the rotation of the filter screen 22, some of the anti-clogging needles 272 extend into the filter holes of the filter screen 22, causing the rotating roller 27 to engage with the filter screen 22. As the filter screen 22 rotates, it drives several rotating rollers 27 to rotate, which in turn drives the anti-clogging needles 272 to rotate. The anti-clogging needles 272 continuously extend into the filter holes of the filter screen 22 during rotation, thereby cleaning the filter screen 22 and achieving the anti-clogging effect. This prevents the filter screen 22 from becoming clogged and affecting the filtration effect of the raw materials. While the rotating roller 27 is rotating, it also drives several protrusions 271 to rotate. During rotation, the protrusions 271 continuously impact the outer wall of the filter screen 22, causing the vibration to be transmitted through the filter screen 22 to the raw materials between the filter screen 22 and the cone 21.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
