Description

Technical Field

[0001] The invention relates to the technical field of composting and fermentation, in particular to a livestock and poultry excrement composting device. Background Art

[0002] Livestock and poultry manure mainly refers to a type of rural solid waste produced in the livestock and poultry breeding industry, including pig manure, cow manure, sheep manure, chicken manure and duck manure. Livestock and poultry manure has always been regarded as an important source of soil fertilizer. Therefore, livestock and poultry manure is mostly applied on-site. Animal excrement contains rich organic matter and nutrients such as nitrogen, phosphorus, and potassium. It can also provide crops with calcium, magnesium, sulfur and other minerals and trace elements to meet the needs of crops for multiple nutrients during growth. Livestock and poultry manure composting is an organic fertilizer made from livestock and poultry manure as the main raw material through composting and decomposition. It contains relatively rich nutrients, and the fertilizer effect is long and stable. At the same time, it is beneficial to promote the formation of soil solid particle structure, and can increase the soil's ability to retain water, heat, air permeability and fertilizer.

[0003] In order to solve the problem that "it is difficult for the existing equipment to stir the raw materials at the bottom layer to the upper layer during stirring", a Chinese patent with the publication number CN219449578U discloses a livestock and poultry manure composting fermentation device, including a fermentation tank, a first motor is fixedly installed at the center position of the top surface of the fermentation tank, a driving shaft that penetrates the inner side of the fermentation tank is fixed to the output end of the first motor, a frame is fixed to the outer side of the driving shaft, and a lifting component and a transmission component for driving the lifting component to operate to lift the raw materials in the fermentation tank upward are arranged on the frame; the first motor drives the frame to rotate to mix the livestock and poultry manure raw materials added to the fermentation tank, and at the same time, the second motor is turned on to drive the first pulley to rotate, and under the transmission action of the belt, the guide rollers on both sides can be driven to rotate synchronously, thereby driving the transmission belt to rotate in the fermentation tank, and during the rotation of the transmission belt, the raw materials in the fermentation tank can be lifted from bottom to top by the partition to achieve mixing and stirring of the upper and lower layers of raw materials. Although the existing technical problems have been solved, the following problems still exist:

[0004] In this technical solution, although the partition can continuously transport feces upward by rotating the transmission belt, it can only be transported within a fixed range and there are large blind spots. Therefore, corresponding improvements are made to address this problem. Summary of the invention

The main shaft 5 is connected with a driving component, and a push-pull component is also arranged in the cylinder 1. The driving component is used to drive the main shaft 5 to rotate, and the push-pull component is used to drive the conveyor belt 10 and the sleeve 9 to move laterally as a whole. Livestock and poultry manure is added to the cylinder 1 through the feed pipe 2, and then the main shaft 5 and the stirring frame 6 are driven to rotate for stirring through the driving component. At the same time, the roller 15 will roll on the circular rail 14 to drive the shaft rod 8 to rotate, and then the shaft rod 8 will drive the conveyor belt 10 to rotate through the sleeve 9, and the manure can be continuously transported upward through the partition 11, thereby forming a good stirring effect.

[0039] Among them, the driving component includes a motor 20, which is fixed at the top of the cylinder 1. The first gear 21 and the second gear 22 are respectively installed on the output shaft of the motor 20 and the main shaft 5. The first gear 21 and the second gear 22 are meshed and connected.

When the main shaft 5 rotates, the second bevel gear 34 is synchronously driven to rotate, and the second bevel gear 34 is meshed to drive the first bevel gear 33 to rotate. Then the first bevel gear 33 synchronously drives the shaft column 32 to rotate, and then the shaft column 32 will drive the vertical rod 28 to move upward periodically through the transmission structure, and then the vertical rod 28 will pull the pull rope 26 upward through the top plate 27, and the other end of the pull rope 26 will pull the sleeve 9, thereby driving the sleeve 9 and the conveyor belt 10 to move as a whole.

[0044] Among them, a guide sleeve 29 is fixed on the outside of the vertical rod 28, a guide column 30 is inserted into the guide sleeve 29, and the guide column 30 is fixed to the top of the cylinder 1, so that the vertical rod 28 can be limited and moved in the up and down directions through the sliding cooperation between the guide sleeve 29 and the guide column 30.

[0045] Among them, the transmission structure includes a disc 35, which is fixed at the end of the shaft column 32. A support rod 36 is rotatably connected to the edge of the disc 35. The other end of the support rod 36 is rotatably connected to the vertical rod 28. When the shaft column 32 rotates, the disc 35 is synchronously driven to rotate, and then the disc 35 will pull the vertical rod 28 through the support rod 36, so that the vertical rod 28 moves up and down periodically.

[0046] In Example 3, the transmission structure includes a cam 37, which is fixedly mounted on the shaft column 32. A blocking block 38 abutting against the cam 37 is fixed on the inner side of the vertical rod 28. When the shaft column 32 rotates, the cam 37 is synchronously driven to rotate. The cam 37 will periodically push the blocking block 38 upward, thereby causing the vertical rod 28 to move up and down periodically.

[0047] In Example 4, the push-pull assembly includes a pair of sleeve rods 39 fixedly mounted on the connecting rod 12, a first magnet 40 is fixed to the outer end of the sleeve rod 39, and a plurality of second magnets 41 distributed in a circular array are fixed to the inner circumferential wall of the cylinder 1. When the first magnet 40 and the second magnet 41 are close to each other, the magnetic repulsion force between the first magnet 40 and the second magnet 41 will act on the sleeve rod 39, thereby driving the sleeve 9 and the conveyor belt 10 to move as a whole through the connecting rod 12.
