[0002] In the poultry and livestock farming industry, the excrement, such as feces and urine produced by poultry and livestock, generally seeps downward through a slatted floor. A circulating conveyor belt is arranged below the slatted floor to transport the excrement to a collection trough for centralized treatment.

[0003] In existing technologies, livestock excrement accumulates on and adheres to circulating conveyor belts after continuous use, requiring periodic manual cleaning to prevent damage and ensure their continued usability. However, manual cleaning is cumbersome, necessitating improvements to the existing structure to address these issues. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a livestock excrement conveying device with self-cleaning function, which solves the technical problem that manual cleaning of conveyor belts is cumbersome in related technologies.

[0005] According to one aspect, at least one embodiment of the present invention provides a livestock excrement conveying device with a self-cleaning function, comprising a manure slat plate, a side baffle, and a circulating conveyor belt arranged sequentially from top to bottom.

A limiting member that moves axially is provided in the through hole. The end of the limiting member near the groove has an arc surface. A cleaning brush is inserted into the groove. The side wall of the cleaning brush near the through hole has a chamfer. A limiting hole is provided above the chamfer. The cleaning brush is configured such that when inserted into the groove, the chamfer presses the arc surface to move the limiting member away from the groove, so that the limiting member is aligned with the limiting hole and engages in the limiting hole.

[0008] As a further technical solution, the through hole includes a large-diameter hole and a small-diameter hole that are connected. The large-diameter hole is closer to the groove than the small-diameter hole. An elastic element is provided in the large-diameter hole. One end of the elastic element acts on the limiting element, and the other end acts on the side end of the large-diameter hole, so as to provide a force for the limiting element to move toward the groove and engage with the limiting hole.

[0009] As a further technical solution, the end of the limiting member away from the groove extends out of the through hole and has a limiting part for locking the end of the through hole.

[0010] As a further technical solution, a pull rod is provided on the limiting part.

[0011] As a further technical solution, the groove sidewall has a radially extending slot, and the cleaning brush has a locking block for locking into the slot.

[0012] As a further technical solution, a number of cleaning brushes are evenly arranged on the peripheral wall of the cleaning roller.

[0013] As a further technical solution, the side baffle has an inclined guide surface, which is used to guide the excrement onto the circulating conveyor belt.

[0014] The beneficial effects of this utility model are as follows: In this invention, the cooperative structure formed by the cleaning roller and the circulating conveyor belt allows the cleaning roller to clean the ends of the circulating conveyor belt simultaneously while it conveys excrement, eliminating the need for frequent machine shutdowns for manual cleaning.

[0023] The self-cleaning livestock excrement conveying equipment provided in this embodiment is mainly applied to centralized excrement treatment scenarios in large-scale livestock farms. In the livestock farming industry, to achieve a clean farming environment and efficient excrement recycling, a layered structure is usually used for excrement leakage and conveying. That is, the excrement is allowed to seep naturally through the upper slatted floor, and the lower conveying components transfer the excrement to the designated collection area. This equipment is a structural optimization based on the fundamental needs of this field.

[0024] like Figure 1 As shown, the conveying equipment consists of a manure slatted floor 1, side baffles 2, and a circulating conveyor belt 3 arranged sequentially from top to bottom. The manure slatted floor 1 is horizontally positioned to support livestock and allow excrement to leak downwards. The side baffles 2 are vertically installed on both sides of the circulating conveyor belt 3, forming a enclosure structure with the edge of the circulating conveyor belt 3. The circulating conveyor belt 3 adopts a closed-loop structure, which can continuously circulate around the drive rollers on the equipment frame, thereby conveying the collected excrement in a preset direction. A cleaning roller 4 is fitted to one end of the circulating conveyor belt 3. The cleaning roller 4 is rotatably connected to the equipment frame via a rotating shaft, and its rotation axis is consistent with the width extension direction of the circulating conveyor belt 3. The peripheral wall of the cleaning roller 4 is in close contact with the end surface of the circulating conveyor belt 3 to remove residual excrement adhering to the end of the circulating conveyor belt 3.

[0025] The peripheral wall of the cleaning roller 4 can fully cover the end width of the circulating conveyor belt 3, ensuring that the cleaning effect covers the entire width range of the end of the circulating conveyor belt 3, thus improving the comprehensiveness of cleaning the end of the circulating conveyor belt 3. The cooperative structure formed by the cleaning roller 4 and the circulating conveyor belt 3 allows the cleaning roller 4 to clean the end of the circulating conveyor belt 3 simultaneously while it is conveying excrement, eliminating the need for frequent machine shutdowns for manual cleaning. This solves the problem of cumbersome manual cleaning in existing technologies, reduces equipment downtime, and improves equipment operating efficiency. The continuous cleaning of the end of the circulating conveyor belt 3 by the cleaning roller 4 can prevent excrement from adhering and accumulating on the end of the circulating conveyor belt 3 for a long time, reducing corrosion and wear caused by excrement, and extending the service life of the circulating conveyor belt 3. Through the combination of various components, the overall structure, while achieving efficient excrement conveying, endows the equipment with a self-cleaning function through the setting of the cleaning roller 4. This eliminates the need for additional complex cleaning mechanisms, simplifies the overall structure of the equipment, and improves its practicality and operational stability.

[0026] Optionally, the two ends of the circulating conveyor belt 3 along its length are the excrement discharge end and the cleaning end, respectively. The excrement discharge end is the end where the excrement leaves the circulating conveyor belt 3 and falls into the collection trough, while the cleaning roller 4 is located at the cleaning end, that is, the other end of the circulating conveyor belt 3 away from the excrement discharge end. This arrangement makes the cleaning area of ​​the cleaning roller 4 independent from the excrement discharge area, avoiding interference between the cleaning process and the excrement discharge process.

[0027] Furthermore, such as Figure 3 and Figure 5 As shown, a groove 41 extending axially is formed on the peripheral wall of the cleaning roller 4, and a through hole 42 extending axially along the cleaning roller 4 is formed through the side wall of the groove 41. A limiting member 43 that can move axially is inserted into the through hole 42, and the end of the limiting member 43 near the groove 41 is machined with an arc surface 431. A cleaning brush 44 is inserted into the groove 41, and the side wall of the cleaning brush 44 near the through hole 42 is provided with a chamfer 45. The chamfer 45 is located at the end of the cleaning brush 44 inserted into the groove 41, and a limiting hole 411 is provided above the chamfer 45. When the cleaning brush 44 is inserted into the groove 41, the chamfer 45 will press against the arc surface 431 of the limiting member 43, forcing the limiting member 43 to move away from the groove 41. When the cleaning brush 44 is inserted to the preset position, the limiting member 43 and the limiting hole 411 are just aligned. At this time, the limiting member 43 moves towards the groove 41 and is locked into the limiting hole 411, thus realizing the fixed connection between the cleaning brush 44 and the cleaning roller 4.

[0028] By providing a limiting member 43 with an arc surface 431 on the side wall of the groove 41 of the cleaning roller 4, and cooperating with the chamfer 45 and the limiting hole 411 on the cleaning brush 44, a connection structure that can be completed without additional tools is formed, simplifying the assembly process of the cleaning brush 44 and the cleaning roller 4. When the cleaning brush 44 is inserted, the squeezing action of the chamfer 45 and the arc surface 431 can drive the limiting member 43 to automatically avoid it, eliminating the need for manual operation of the limiting member 43 and improving assembly efficiency; while the engaging structure of the limiting member 43 and the limiting hole 411 ensures the reliability of the connection between the cleaning brush 44 and the cleaning roller 4, preventing the cleaning brush 44 from falling off during the rotation of the cleaning roller 4. At the same time, this structure achieves positioning and fixation through mechanical cooperation, allowing for quick assembly and disassembly of the cleaning brush 44.

[0029] Optionally, the through hole 42 consists of a large-diameter hole 421 and a small-diameter hole 422 that are interconnected. The large-diameter hole 421 is located on the side closer to the groove 41, and the small-diameter hole 422 is located on the side farther from the groove 41. An elastic element 46 is installed in the large-diameter hole 421. One end of the elastic element 46 abuts against the end of the limiting member 43, and the other end abuts against the side end of the large-diameter hole 421 away from the groove 41. The elastic element 46 can be a spring, which is always in a pre-compressed state and can continuously provide a thrust to the limiting member 43 in the direction of the groove 41, ensuring that the limiting member 43 can automatically engage when aligned with the limiting hole 411, thus improving the ease of assembly.

[0030] Furthermore, such as Figure 4 and Figure 6 As shown, the end of the limiting member 43 away from the groove 41 passes through the through hole 42 and extends to the outside of the cleaning roller 4. This extended end is provided with a limiting portion 461, the radial dimension of which is larger than the diameter of the through hole 42 at the end away from the groove 41. When the elastic member 46 pushes the limiting member 43 towards the groove 41, the limiting portion 461 abuts against the end of the through hole 42, thereby limiting the maximum travel of the limiting member 43 and preventing it from excessively extending into the groove 41 and affecting the normal insertion of the cleaning brush 44. A pull rod 462 is also fixedly connected to the limiting portion 461, extending axially along the limiting member 43. The operator can pull the pull rod 462 to drive the limiting member 43 away from the groove 41 to disassemble the cleaning brush 44.

[0031] Optionally, a slot 412 extending radially along the cleaning roller 4 is provided on the side wall of the groove 41, and a corresponding locking block 441 is provided at the position of the cleaning brush 44, the shape of which is adapted to the slot 412. When the cleaning brush 44 is inserted into the groove 41, the locking block 441 moves synchronously with the cleaning brush 44 and locks into the slot 412. This structure, in conjunction with the fixing of the limiting member 43 and the limiting hole 411, achieves dual positioning of the cleaning brush 44 in both the axial and radial directions, further improving the connection stability.

[0032] Furthermore, a number of cleaning brushes 44 are evenly distributed along the circumference of the peripheral wall of the cleaning roller 4, and the extension direction of each cleaning brush 44 is perpendicular to the peripheral wall of the cleaning roller 4. The even arrangement of multiple cleaning brushes 44 can increase the contact area between the cleaning roller 4 and the end of the circulating conveyor belt 3, increase the cleaning frequency per unit time, and reduce cleaning dead corners.

[0033] Optionally, such as Figure 2 As shown, the side baffle 2 has an inclined guide surface 21 machined on its inner side near the circulating conveyor belt 3. The guide surface 21 extends inclinedly from the edge of the slatted floor 1 towards the surface of the circulating conveyor belt 3, that is, the upper end of the guide surface 21 is aligned with the side edge of the slatted floor 1, and the lower end extends above the edge of the circulating conveyor belt 3. When excrement leaks from the edge of the slatted floor 1, it will come into contact with the guide surface 21 and slide down along the guide surface 21, eventually falling onto the circulating conveyor belt 3, thus preventing excrement from scattering through the gap between the slatted floor 1 and the circulating conveyor belt 3.

[0034] The equipment operates as follows: Livestock excrement leaks downwards through the slatted floor 1, with some falling directly onto the circulating conveyor belt 3, and some moving towards the edge of the slatted floor 1 and sliding into the circulating conveyor belt 3 under the guidance of the side baffle 2 guide surface 21. The circulating conveyor belt 3 continuously circulates, transporting the excrement it carries to the lower manure end, where it falls into the collection trough. Simultaneously, the cleaning roller 4 rotates continuously around its own axis under the drive mechanism, and the cleaning brush 44 on its peripheral wall rubs against the surface of the cleaning end of the circulating conveyor belt 3, removing any residual excrement adhering to that end. When the cleaning brush 44 needs to be replaced, the operator pulls the lever 462, which drives the limiting member 43 to compress the elastic member 46 and disengage from the limiting hole 411. At this time, the cleaning brush 44 can be pulled out from the groove 41. When installing a new cleaning brush 44, the cleaning brush 44 is inserted into the groove 41, and the chamfer 45 presses the arc surface 431 of the limiting member 43 to make it avoid the gap. When the locking block 441 is inserted into the slot 412 and the limiting hole 411 is aligned with the limiting member 43, the limiting member 43 automatically engages with the limiting hole 411 under the action of the elastic member 46, thus completing the fixing of the cleaning brush 44.

[0035] In this embodiment, "feces end" refers to the end of the circulating conveyor belt 3 used to discharge excrement, "circulating conveyor belt 3" refers to a belt conveyor component that adopts a closed-loop structure for continuous circulating motion, and "cleaning end" refers to the end of the circulating conveyor belt 3 away from the feces end and equipped with a cleaning roller 4.

[0036] This conveying equipment, through a top-down layout of a slatted floor 1, side baffles 2, and a circulating conveyor belt 3, constructs a stable excrement conveying channel. The side baffles 2 effectively prevent excrement from scattering from the sides of the circulating conveyor belt 3, ensuring the orderly conduction of the conveying process. The cleaning roller 4, located at the cleaning end of the circulating conveyor belt 3, rotates along the same axis as the width extension direction of the belt, ensuring that the perimeter of the cleaning roller 4 fully covers the end width of the belt 3, achieving thorough cleaning. The synchronous operation of the cleaning roller 4 and the circulating conveyor belt 3 allows the cleaning and conveying processes to occur simultaneously, eliminating the need for manual downtime and reducing equipment downtime, thus improving the operational efficiency of the livestock farm.

[0037] The detachable connection structure between the cleaning brush 44 and the cleaning roller 4, through the cooperation of the chamfer 45, the arc surface 431, and the elastic element 46, enables the quick assembly and disassembly of the cleaning brush 44, reducing the difficulty of equipment maintenance. The setting of the limiting part 461 prevents the limiting element 43 from falling off, and the pull rod 462 further improves the ease of operation. The radial engagement of the slot 412 and the locking block 441, along with the axial positioning of the limiting element 43 and the limiting hole 411, fixes the cleaning brush 44 from two directions, effectively preventing the cleaning brush 44 from shifting due to centrifugal force or friction during the rotation of the cleaning roller 4, thus extending the service life of the cleaning brush 44. The multiple cleaning brushes 44 evenly arranged on the periphery of the cleaning roller 4 expand the cleaning coverage area and improve cleaning efficiency. At the same time, the multiple brushes share the cleaning force, reducing the wear rate of individual brushes.

[0038] The inclined guide surface 21 of the side baffle 2 can guide the excrement leaking from the edge to the circulating conveyor belt 3 without additional power, improving the integrity of excrement collection and reducing environmental pollution. The elastic element 46 enables the limiting element 43 to have an automatic reset capability, ensuring that the cleaning brush 44 can be quickly and accurately positioned and fixed each time it is assembled, further optimizing the user experience of the equipment.

[0039] Overall, the equipment, through its reasonable structural design, organically combines self-cleaning and excrement conveying functions. This not only solves the problem of tedious manual cleaning in traditional equipment, but also improves the stability and practicality of the equipment through the synergistic effect of its various components, providing an efficient and feasible solution for excrement treatment in the poultry and livestock farming industry.
