Description

Technical Field

[0001] This utility model relates to the field of manure cleaning machine technology, and in particular to a manure cleaning device for livestock cages. Background Technology

[0002] Large-scale farming is a relatively new farming technology that has emerged in recent years. It mainly refers to a farming method that uses modern farming equipment to increase stocking density and efficiency. Among them, stacked cages are a relatively mature and widely used farming equipment. Stacked cages are mainly composed of stacked cage frames, feeders, and manure removers. The stacked cage frames serve as poultry rearing rooms, the feeders supply feed to the feed troughs outside the rearing rooms, and the manure removers clean up the manure that falls from each layer of the rearing room.

[0003] Currently, most manure removal machines use belt conveyors. The conveyor belt passes over the manure drop area of ​​the stacked cages, carrying away the manure and then scraping it off with cleaning plates. Because the conveyor belt carries manure and is in a wet, sticky state for extended periods, it gradually becomes misaligned, especially in larger stacked cages where the belt is longer and more prone to deviation. While corrective plates are typically installed on both sides of the belt, this often results in the belt edges lifting and the belt surface bulging, and also causes significant friction. Furthermore, the belt is prone to stretching and widening, leading to wrinkles and an uneven surface. Therefore, there is an urgent need for a safe and stable manure removal device for livestock cages. Utility Model Content

[0004] The purpose of this utility model is to provide a manure removal device for breeding cages, so as to solve the problems of belt deviation, belt wrinkles, and uneven belt surface on the existing manure removal machine for breeding cages.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A manure removal device for livestock cages includes a manure removal machine body. The manure removal machine body has rotating rollers and a manure removal belt tensioned on at least two of the rotating rollers. A positioning structure is provided between the rotating rollers and the manure removal belt. The positioning structure includes a positioning protrusion ring disposed on the outer periphery of the rotating rollers and a positioning concave ring disposed on the inner surface of the manure removal belt. The positioning protrusion ring is located inside the positioning concave ring. The outer periphery of the rotating rollers is also provided with spiral protrusions located on both sides of the positioning protrusion rings. The spiral directions of the two spiral protrusions are opposite and face outward.

[0007] A further technical solution is: an idler roller is provided above the rotating roller to press against the manure removal belt.

[0008] A further technical solution is that the idler roller is provided with a cam that is opposite to the helical spacing on the helical protrusion.

[0009] A further technical solution is as follows: the rotating roller is provided with a tensioning mechanism, the tensioning mechanism including a slide, a connecting member, a rotating shaft, a ratchet, and a pawl. The rotating roller is rotatably mounted on the slide, the slide is slidably mounted on the frame of the manure cleaning machine body, the rotating shaft is rotatably mounted on the frame of the manure cleaning machine body, the two ends of the connecting member are respectively connected to the slide and the rotating shaft, the ratchet is mounted on the rotating shaft, one end of the pawl is rotatably connected to the frame of the manure cleaning machine body, and the other end of the pawl is adapted to the ratchet.

[0010] A further technical solution is that the connector is a steel wire rope.

[0011] A further technical solution is that the connecting component is a chain, and a sprocket that meshes with the chain is provided on the rotating shaft.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] This utility model proposes a manure removal device for livestock cages. Based on the traditional belt conveyor, the device sets up a positioning structure between the belt and the roller, which achieves the effects of centering and internal positioning, greatly avoiding belt deviation. Moreover, this positioning method is not visible from the outside, so it is less affected by interference and causes less wear on the belt. In addition, the roller is provided with spiral protrusions with opposite spiral directions at both ends and facing outwards, which can flatten the stretched belt and prevent the belt from wrinkling and causing uneven belt surface.

The manure removal machine body 1 has a rotating roller 2 and a manure removal belt 3 tensioned on at least two rotating rollers 2. A positioning structure is provided between the rotating rollers 2 and the manure removal belt 3. The positioning structure includes a positioning protrusion 4 provided on the outer periphery of the rotating roller 2 and a positioning concave ring 5 provided on the inner surface of the manure removal belt 3. The positioning protrusion 4 is located inside the positioning concave ring 5. Spiral protrusions 6 are also provided on the outer periphery of the rotating roller 2 on both sides of the positioning protrusion 4. The spiral directions of the two spiral protrusions 6 are opposite and face outward.

[0026] The manure removal belt 3 is tensioned by at least two rotating rollers 2, one of which is driven by an external motor. The rotating roller 2 moves the manure removal belt 3 to remove the collected manure. A positioning structure is set between the rotating roller 2 and the manure removal belt 3. The positioning concave ring 5 on the rotating roller 2 is generally set in the center. The manure removal belt 3 is positioned by the rotating roller 2. Moreover, the rotating roller 2 and the manure removal belt 3 rotate together, which not only has a good positioning effect, but also has low friction. The positioning method is not visible from the outside and is less affected by interference. In addition, the rotating roller 2 is provided with spiral protrusions 6 with opposite spiral directions at both ends and facing outwards. This can flatten the stretched manure removal belt 3 and prevent the manure removal belt 3 from wrinkling and causing uneven belt surface.

[0027] Preferably, an idler roller 7 is provided above the rotating roller 2 to press against the manure cleaning belt 3.

[0028] The idler roller 7 can lift the manure cleaning belt 3 to prevent the manure cleaning belt 3 from being damaged by excessive downward pressure and the positioning recess 5.

[0029] Preferably, the idler roller 7 is provided with a cam 8 that is opposite to the helical spacing on the helical protrusion 6.

[0030] Cam 8 is used to compensate for the lack of support for the manure cleaning belt 3 due to the pitch of the helix. Example

[0031] Based on the above embodiments, this embodiment, for example Figure 4 As shown, the rotating roller 2 is equipped with a tensioning mechanism 9, which includes a slide 10, a connecting piece 11, a rotating shaft 12, a ratchet 13, and a pawl 14. The rotating roller 2 is rotatably mounted on the slide 10, and the slide 10 is slidably mounted on the frame of the manure cleaning machine body 1. The rotating shaft 12 is rotatably mounted on the frame of the manure cleaning machine body 1. The two ends of the connecting piece 11 are respectively connected to the slide 10 and the rotating shaft 12. The ratchet 13 is mounted on the rotating shaft 12. One end of the pawl 14 is rotatably connected to the frame of the manure cleaning machine body 1, and the other end of the pawl 14 is adapted to the ratchet 13.

[0032] The tensioning mechanism 9 can adjust the position of the slide block 10, i.e. the rotating roller 2, when the belt is stretched, thereby maintaining the tension of the manure cleaning belt 3. Specifically, it tightens the connecting piece 11 through the rotating shaft 12, and then prevents the rotating shaft 12 from reversing through the cooperation of the pawl 14 and the ratchet 13.

[0033] Preferably, the connector 11 is a steel wire rope.

[0034] Preferably, the connector 11 is a chain, and the shaft 12 is provided with a sprocket 15 that meshes with the chain.

[0035] The sprocket 15 and chain drive are stable, preventing slippage between them.
