[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] like Figures 1 to 4 As shown, a household cow manure composting device according to the first aspect of this utility model includes: a lower chamber 2 integrally fixedly installed on the outer side of the lower end of an upper chamber 1, and compensation blocks 3 fixedly installed on the bottom corners of the left and right sides of the lower end of the lower chamber 2. The inner longitudinal section of the lower chamber 2 is "U"-shaped. The compensation blocks 3 can compensate for the top corners on the left and right sides of the lower chamber 2. At the same time, through the "U"-shaped setting of the lower chamber 2 and the installation of the compensation blocks 3, there are no dead corners at the bottom of the lower chamber 2. Thus, when the cow manure raw material is composted in the lower chamber 2, there is no phenomenon of cow manure raw material accumulating in dead corners and being unable to be turned over, which can effectively improve the overall composting efficiency. A feeding hopper 4 is installed in the middle of the upper end of the upper chamber 1, and a sealing cover is set on the outer side of the upper end of the feeding hopper 4 through a hinge shaft. When composting, the sealing cover is opened and the cow manure raw material is poured into the feeding hopper 4 and the upper chamber 1.
[0026] The mounting rails 5 and the reciprocating screws 7 are arranged in a one-to-one correspondence. The mounting rails 5 play a good role in installing the reciprocating screws 7, and the spacing of the mounting rails 5 is larger than the inner diameter of the lower end of the feed hopper 4, which can shield the mounting rails 5 and prevent the cow manure raw material from falling to the outside of the mounting rails 5. The drive motor 6 is set on the top right side of the upper chamber 1, and the output end of the drive motor 6 is connected to the reciprocating screws 7 located inside the upper chamber 1. The mounting rails 5 are fixedly installed at the front and rear ends of the inner top of the upper chamber 1 by screws, and the reciprocating screws 7 are rotatably installed on the inner end of the mounting rails 5. Start the drive motor 6, which drives the reciprocating screw 7 to rotate inside the mounting rail 5 and the upper chamber 1. At the same time, the transmission belt 8 set on the outer side of the right end of the reciprocating screw 7 drives the two sets of reciprocating screws 7 to rotate synchronously. The transmission block 9 is set on the outer side of the reciprocating screw 7, and the lower outer side of the transmission block 9 is fixed with a support rod 10 by screws. When the reciprocating screw 7 rotates, it is threadedly connected to the transmission block 9, thereby driving the transmission block 9 and the support rod 10 to move horizontally left and right inside the upper chamber 1.
[0027] A support frame 11 is provided on the outside of the support rod 10, and a stirring rod 12 is rotatably installed inside the lower end of the support frame 11. Stirring blades 13 are evenly spaced on the outside of the stirring rod 12, with the length of the stirring blades 13 decreasing sequentially from the middle to both sides of the stirring rod 12. The support frame 11 provides good installation and support for the stirring rod 12, and facilitates the horizontal movement of the stirring rod 12 within the upper chamber 1 via the support rod 10 and support frame 11. A motor connected to the rear end of the stirring rod 12 can be activated, causing the stirring rod 12 and stirring blades 13 to rotate. This rotation facilitates thorough turning of the cow manure material by the stirring blades 13, ensuring uniform fermentation and improving compost quality. During fermentation, the exhaust pipe at the top of the upper chamber 1 can be opened to release excess gas. The movement trajectory of the stirring blades 13 is matched to the length of the installation track 5, thus preventing collisions between the stirring blades 13 and the upper chamber 1 during rotation.
[0028] A fixed insert rod 15 is inserted through the connection between the support rod 10 and the support frame 11. The lower end of the support rod 10 extends through to the front and rear ends of the support frame 11. The upper and lower ends of the support frame 11 are fixedly installed with pointed structures located on the outside of the support rod 10. This facilitates the scraping of cow dung material adhering to the outside of the support rod 10 through the pointed structures, preventing the cow dung material from affecting the height adjustment of the support frame 11. The support rod 10 has through holes that are equally spaced and adapted to the fixed insert rod 15. The support rod 10 is symmetrically arranged about the vertical central axis of the support frame 11. When it is necessary to adjust the height of the stirring rod 12 and the stirring blade 13, the support frame 11 can be adjusted to the specified position on the outside of the support rod 10 so that the through hole structure of the support frame 11 and the support rod 10 are aligned. Then, the fixing rod 15 is inserted into the inside of the support frame 11 and the support rod 10 to fix the support frame 11. The front middle of the upper silo body 1 is equipped with a silo door 14 through a hinge. Opening the silo door 14 facilitates the transportation of compost materials.
