Description

Technical Field

[0001] This invention relates to the field of material screening technology, specifically a screening machine for preventing feed clogging in livestock farming. Background Technology

[0002] In the field of animal husbandry, especially in large-scale farming, scientific feeding is an important part of ensuring the healthy growth of livestock. To ensure feed quality and palatability, feed usually needs to be screened before feeding to remove impurities, dust and lumps, and to achieve uniform particle size, thereby improving feed intake and digestion efficiency.

[0003] However, feed is susceptible to moisture, compression, or static electricity during storage and transportation, causing particles to clump together. When existing screening devices are in operation, as the screening time increases, these clumps gradually accumulate on the screen surface and in dead corners. This requires frequent manual shutdowns for cleaning and collection, followed by transfer to a clump-breaking device. This process not only interrupts operations and increases labor intensity but also significantly reduces overall feeding efficiency. Furthermore, current clump-breaking methods mostly rely on mechanical hammering, which makes it difficult to precisely control the force, easily leading to over-grinding of feed and unnecessary powder loss, which in turn exacerbates resource waste and increases costs. Summary of the Invention

[0004] The purpose of this invention is to provide a screening machine for preventing livestock feed from clumping, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A screening machine for preventing feed agglomeration in livestock farming includes a support and further includes:

[0007] A first support member and a second support member are fixed on the support and arranged opposite to each other. A cylinder is rotatably installed between the two. The cylinder is provided with multiple screen plates, and a first end cap and a second end cap are fixed at both ends of the cylinder respectively. The first support member is provided with a feeding mechanism. The cylinder can be driven by a power mechanism provided on the support to perform a rotation action.

[0008] The feeding mechanism is located inside the cylinder. It is triggered when the cylinder rotates, moves along the axial direction of the cylinder, and can push the feed that enters the cylinder through the feeding mechanism.

[0009] A clod breaking mechanism located inside a cylinder is capable of relative movement with the cylinder along its axial direction as the cylinder rotates.

[0010] The above-mentioned screening machine for preventing livestock feeding and solidification: the feeding mechanism includes a feeding hopper fixed on the first support member, and the cylinder is provided with multiple openings, which are equidistantly distributed along the circumference and are enveloped by the first support member;

[0011] The inner wall of the cylinder is also fixed with a plurality of strip-shaped protrusions that are equidistantly distributed along the circumference, and the strip-shaped protrusions are inclined.

[0012] The livestock feeding and anti-agglomeration screening machine as described above: the power mechanism includes a drive motor mounted on the support and a gear fixed on the output shaft of the drive motor. A gear ring is also fixed on the cylinder, and the gear ring meshes with the gear.

[0013] The above-mentioned livestock feeding and anti-agglomeration screening machine: the pushing mechanism includes a pushing plate movably disposed inside the cylinder, the pushing plate slidingly fitting against the inner wall of the cylinder;

[0014] The pusher plate is fixedly connected to a crossbar, which is slidably connected to the second end cap and concentric with the cylinder. The crossbar is connected to two sets of elastic structures on the first support member, and the elastic structures are provided with a rolling fit structure with the second end cap.

[0015] The livestock feeding and anti-agglomeration screening machine as described above: the elastic structure includes a protruding block fixed on the first support member, a connecting rod slidably connected to the protruding block, and a first columnar spring sleeved on the outer periphery of the connecting rod.

[0016] The connecting rod is fixed to the crossbar via a cross arm, one end of the first cylindrical spring is connected to the protruding block, and the other end is connected to a frustum fixed to the end of the connecting rod away from the cross arm.

[0017] The livestock feeding and anti-agglomeration screening machine described above: the rolling cooperation structure includes a roller mounted on the cross arm and a limiting ring fixed on the second end cover. The limiting ring has a plurality of limiting protrusions distributed equidistantly along the circumference. A first smooth surface and a second smooth surface are formed on both sides of the limiting protrusions, respectively. The first smooth surface is inclined, and the second smooth surface is perpendicular to the end face of the limiting ring.

[0018] The sieving machine for preventing agglomeration in livestock feeding as described above: the agglomeration breaking mechanism includes a horizontal shaft concentric with the cylinder and slidably connected to the first end cap, and an arc-shaped plate connected to the horizontal shaft by two sets of elastic connecting components.

[0019] A slit is formed between the arc-shaped plate and the inner wall of the cylinder, and the arc-shaped plate has a first inclined portion on both sides and a second inclined portion at the end away from the first end cap. The horizontal axis can be driven by a pneumatic component mounted on the support to reciprocate along the axial direction of the cylinder.

[0020] The livestock feeding and anti-agglomeration screening machine described above: the outer wall of the horizontal shaft has two protrusions, the protrusions are elongated and parallel to the central axis of the horizontal shaft, the center of the first end cover is provided with a through hole for the horizontal shaft to pass through, and the inner wall of the through hole is provided with a groove adapted to the protrusions.

[0021] The above-mentioned livestock feeding and anti-clumping screening machine: the elastic connection assembly includes a column fixed to the arc plate and a second columnar spring sleeved on the outer periphery of the column. The column is slidably connected to a connecting block fixed on the outer wall of the horizontal axis. The two ends of the second columnar spring are respectively connected to the arc plate and the connecting block.

[0022] The livestock feeding and anti-agglomeration screening machine as described above: a guide rail is fixed on the side of the support, the pneumatic component includes a transverse plate that is slidably fitted on the guide rail and a cylinder that is rotatably mounted on the support, the movable end of the cylinder is rotatably connected to the transverse plate, a connecting arm is fixedly mounted on the transverse plate, and the connecting arm is rotatably connected to the transverse shaft.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This invention utilizes a pusher plate that is movable within a cylinder. As the cylinder rotates, the cooperation between the rollers and multiple limiting protrusions on the limiting ring compresses the first cylindrical spring, followed by an instantaneous rebound. This causes the pusher plate to push the feed within the cylinder. On one hand, this allows the feed to smoothly reach the positions of the multiple strip-shaped protrusions, facilitating its flow along the cylinder's axial direction. On the other hand, because the rebound of the first cylindrical spring is instantaneous, the pusher plate pushes the feed rapidly, causing the agglomerated material to collide with the strip-shaped protrusions, thus achieving primary agglomeration of the feed.

[0025] Secondly, by setting an arc-shaped plate in the cylinder and forming a slit between the arc-shaped plate and the inner wall of the cylinder, the cohesive feed located in the slit is subjected to pressure under the elastic support of the second columnar spring. The arc-shaped plate moves back and forth along the axial direction of the cylinder, which can perform a two-stage breaking process of the feed by elastic kneading.

[0026] Therefore, this screening machine integrates primary and secondary agglomeration processing functions, eliminating the need for frequent manual shutdowns for cleaning and collection, and subsequent transfer to agglomeration equipment for further processing. This effectively improves feeding efficiency, and the feed is kneaded and broken up in the narrow gap between the arc plate and the inner wall of the cylinder, avoiding the problem of excessive crushing caused by mechanical beating, thus preventing further waste of resources and increased costs.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0040] Please see Figures 1-10 In this embodiment, a screening machine for preventing livestock feed from clumping includes a support 1, and further includes:

[0041] A first support member 2 and a second support member 3 are fixed on the support 1 and arranged opposite to each other. A cylinder 5 is rotatably installed between the two. Multiple screen plates 6 are provided on the cylinder 5. A first end cap 11 and a second end cap 12 are fixed at both ends of the cylinder 5 respectively. A feeding mechanism is provided on the first support member 2. The cylinder 5 can be driven by a power mechanism provided on the support 1 to perform a rotation action.

[0042] The feeding mechanism is located inside the cylinder 5. It is triggered when the cylinder 5 rotates, moves along the axial direction of the cylinder 5, and can push the feed that enters the cylinder 5 through the feeding mechanism.

[0043] The clod breaking mechanism is located inside the cylinder 5. The clod breaking mechanism can move relative to the cylinder 5 along the axial direction of the cylinder 5 when the cylinder 5 rotates.

[0044] In this embodiment, it should be further noted that two arc-shaped baffles 26 are also fixedly installed on the support 1. The two arc-shaped baffles 26 are respectively located on both sides of the cylinder 5. During the screening operation, the two arc-shaped baffles 26 can stop the screened feed and prevent the feed from being thrown out due to centrifugal force. In addition, an inclined feeding plate 27 is also fixed on the support 1. The feeding plate 27 is located below the cylinder 5. After the material is screened, it can fall onto the feeding plate 27 and slide down.

[0045] Secondly, specifically, the cylinder 5 is provided with multiple mounting ports, and the sieve plate 6 is adapted to the mounting ports and is installed in a detachable manner, which facilitates the removal of the sieve plate 6 during routine maintenance.

[0046] As a further embodiment of the present invention, please refer again. Figure 3 , Figure 4 , Figure 6 as well as Figure 8 The feeding mechanism includes a feeding hopper 4 fixed on the first support member 2. The cylinder 5 is provided with a plurality of openings 501, which are equidistantly distributed along the circumference and are enveloped by the first support member 2.

[0047] The inner wall of the cylinder 5 is also fixed with a plurality of strip-shaped protrusions 502 that are equidistantly distributed along the circumference, and the strip-shaped protrusions 502 are inclined.

[0048] In this embodiment, when performing the screening operation, the feed to be screened is fed into the feed hopper 4, and then the feed will enter the cylinder 5 through the opening 501. Therefore, the setting of multiple openings 501 can avoid the problem of inconvenience in adding feed due to the rotation state of the cylinder 5 during the screening process.

[0049] During the screening process, the pushing mechanism works to push the feed into the cylinder 5 toward the center. Furthermore, since the multiple strip protrusions 502 move together with the cylinder 5 and are inclined, they can convey the feed and promote its movement in the axial direction of the cylinder 5. On the other hand, they can also promote the flow of the feed and improve the screening efficiency.

[0050] As a further embodiment of the present invention, please refer again. Figure 3The power mechanism includes a drive motor 7 mounted on the support 1 and a gear 8 fixed on the output shaft of the drive motor 7. A gear ring 9 is also fixed on the cylinder 5, and the gear ring 9 meshes with the gear 8.

[0051] In this embodiment, when the screening operation is performed, the drive motor 7 is turned on, driving the gear 8 to rotate, and the gear 8 can then drive the cylinder 5 to rotate through the gear ring 9.

[0052] It should be noted that the drive motor 7 is a speed-regulating motor. In actual operation, the operator can adjust the rotation speed of the cylinder 5 according to the requirements to achieve better processing results.

[0053] As a further embodiment of the present invention, please refer again. Figure 6 and Figure 9 The pushing mechanism includes a pushing plate 10 movably disposed inside the cylinder 5, and the pushing plate 10 slides against the inner wall of the cylinder 5;

[0054] The pusher plate 10 is fixedly connected to a crossbar 14, which is slidably connected to the second end cap 12 and is concentric with the cylinder 5. The crossbar 14 is connected to two sets of elastic structures provided on the first support member 2, and the elastic structures are provided with a rolling fit structure with the second end cap 12.

[0055] Furthermore, during the rotation of the cylinder 5, since the crossbar 14 is concentric with the cylinder 5 and slidably connected to the second end cap 12, the pusher plate 10 will not move with the cylinder 5. However, the rolling engagement structure triggers the elastic structure to cause the crossbar 14 to reciprocate along the axial direction of the cylinder 5, thereby causing the crossbar 14 to drive the pusher plate 10 to reciprocate along the axial direction of the cylinder 5. When the pusher plate 10 moves away from the second end cap 12 along the axial direction of the cylinder 5, it can apply a pushing force to the feed that enters the cylinder 5 through the opening 501, thereby pushing the feed to the position of the multiple strip protrusions 502, so that the feed can continue to flow along the axial direction of the cylinder 5, improving screening efficiency and ensuring smooth screening, and effectively preventing excessive accumulation of feed at one end of the cylinder 5.

[0056] As a further embodiment of the present invention, the elastic structure includes a protruding block 201 fixedly disposed on the first support member 2, a connecting rod 16 slidably connected to the protruding block 201, and a first cylindrical spring 17 sleeved on the outer periphery of the connecting rod 16; the connecting rod 16 is fixed to the crossbar 14 via a cross arm 15, one end of the first cylindrical spring 17 is connected to the protruding block 201, and the other end is connected to a frustum 1601 fixed to the end of the connecting rod 16 away from the cross arm 15.

[0057] Please refer to it again. Figure 7 The rolling fit structure includes a roller 1501 mounted on the cross arm 15 and a limiting ring 13 fixed on the second end cover 12. The limiting ring 13 has a plurality of limiting protrusions distributed equidistantly along the circumference. A first smooth surface 1301 and a second smooth surface 1302 are formed on both sides of the limiting protrusions, respectively. The first smooth surface 1301 is inclined, and the second smooth surface 1302 is perpendicular to the end face of the limiting ring 13.

[0058] In this embodiment, with attachment Figure 7 Taking the shown state as an example, at this time, the roller 1501 abuts against the limiting ring 13. During the operation, when the cylinder 5 rotates (counterclockwise), the roller 1501 will roll along the limiting ring 13 and pass through multiple limiting protrusions. The roller 1501 first rolls along the first smooth surface 1301. At this time, the roller 1501 drives the horizontal arm 15 to move aside. The horizontal arm 15 pulls the pusher plate 10 in the cylinder 5 toward the second end cover 12 through the horizontal bar 14. Correspondingly, the connecting rod 16... The roller 1501 slides relative to the protrusion 201, causing the first cylindrical spring 17 to be compressed. Subsequently, the roller 1501 disengages from the first smooth surface 1301. Since the second smooth surface 1302 is perpendicular to the end face of the limiting ring 13, the first cylindrical spring 17 will rebound instantly, causing each component to quickly reset. The pusher plate 10 moves away from the second end cover 12 along the axial direction of the cylinder 5, pushing the feed that enters the cylinder 5 through the opening 501 to the position of the multiple strip protrusions 502.

[0059] Therefore, by movably setting the pusher plate 10 in the cylinder 5, when the cylinder 5 rotates, the first cylindrical spring 17 is first compressed by the cooperation of the roller 1501 and the multiple limiting protrusions on the limiting ring 13, and then rebounds instantaneously, causing the pusher plate 10 to push the feed in the cylinder 5. On the one hand, the feed can smoothly reach the position of the multiple strip protrusions 502, which facilitates the flow of feed in the axial direction of the cylinder 5. On the other hand, since the rebound of the first cylindrical spring 17 is instantaneous, the pusher plate 10 pushes the feed quickly, which can cause the agglomerated material to collide with the strip protrusions 502, thereby achieving primary agglomeration treatment of the feed.

[0060] As a further embodiment of the present invention, please refer again. Figure 2 , Figure 4 as well as Figure 6 The clod breaking mechanism includes a horizontal shaft 18 concentric with the cylinder 5 and slidably connected to the first end cap 11, and an arc-shaped plate 21 connected to the horizontal shaft 18 by two sets of elastic connecting components. A slit is formed between the arc-shaped plate 21 and the inner wall of the cylinder 5. The arc-shaped plate 21 has a first inclined portion 2101 on both sides and a second inclined portion 2102 at the end away from the first end cap 11. The horizontal shaft 18 can be driven by a pneumatic component on the support 1 to reciprocate along the axial direction of the cylinder 5.

[0061] Please refer to it again. Figure 10 The outer wall of the horizontal shaft 18 has two protrusions 1801. The protrusions 1801 are elongated and parallel to the central axis of the horizontal shaft 18. The center of the first end cap 11 has a through hole 1101 for the horizontal shaft 18 to pass through, and the inner wall of the through hole 1101 has a groove that matches the protrusions 1801.

[0062] In this embodiment, when the cylinder 5 rotates, the first end cap 11 can drive the horizontal shaft 18 to rotate together through the sliding groove and the protrusion 1801, so the arc plate 21 can rotate synchronously with the cylinder 5.

[0063] At the same time, the movement of the pneumatic component causes the horizontal shaft 18 to drive the arc plate 21 to reciprocate along the axial direction of the cylinder 5. The arrangement of the first inclined part 2101 and the second inclined part 2102 facilitates the feed to enter the narrow gap between the arc plate 21 and the inner wall of the cylinder 5 and be broken up.

[0064] As a further embodiment of the present invention, please refer again. Figure 10The elastic connection assembly includes a column 19 fixed to the arc plate 21 and a second column spring 20 sleeved on the outer periphery of the column 19. The column 19 is slidably connected to a connecting block 1802 fixed on the outer wall of the horizontal axis 18. The two ends of the second column spring 20 are respectively connected to the arc plate 21 and the connecting block 1802.

[0065] In this embodiment, when the pneumatic component operates, the arc plate 21 reciprocates along the axial direction of the cylinder 5. In this state, the feed enters the slit between the arc plate 21 and the inner wall of the cylinder 5. The second cylindrical spring 20 is in a compressed state, which causes the feed located in the slit to receive pressure. At the same time, in conjunction with the reciprocating motion of the arc plate 21, the feed can be effectively broken up.

[0066] As a further embodiment of the present invention, a guide rail 23 is fixed to the side of the support 1, and the pneumatic assembly includes a transverse plate 24 slidably fitted on the guide rail 23 and a cylinder 25 rotatably mounted on the support 1. The movable end of the cylinder 25 is rotatably connected to the transverse plate 24, and a connecting arm 22 is fixedly mounted on the transverse plate 24. The connecting arm 22 is rotatably connected to the transverse shaft 18.

[0067] In this embodiment, during operation, the movable end of the cylinder 25 performs a reciprocating extension and retraction action, thereby driving the transverse plate 24 to reciprocate horizontally sliding on the guide rail 23, and driving the transverse shaft 18 to move along the axial direction of the cylinder 5 through the connecting arm 22.

[0068] In detail, the present invention provides an arc-shaped plate 21 in the cylinder 5, and a slit is formed between the arc-shaped plate 21 and the inner wall of the cylinder 5. Under the elastic support of the second columnar spring 20, the cohesive feed located in the slit is subjected to pressure. The arc-shaped plate 21 moves back and forth along the axial direction of the cylinder 5, thereby enabling the feed to undergo a two-stage elastic kneading breaking process.

[0069] Therefore, this screening machine integrates primary and secondary agglomeration processing functions, eliminating the need for frequent manual shutdowns for cleaning and collection, and subsequent transfer to agglomeration equipment for further processing. This effectively improves feeding efficiency. Furthermore, the feed is kneaded and agglomerated in the narrow gap between the arc plate 21 and the inner wall of the cylinder 5, avoiding excessive crushing caused by mechanical beating and preventing further waste of resources and increased costs.

[0070] 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.

[0071] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
