Description

Technical Field

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

[0002] Composting agricultural waste is a widely used method for resource treatment of agricultural waste. It uses plant agricultural waste (such as straw and fungus residue) and animal manure waste (such as chicken manure and pigeon manure) to mix and ferment to produce organic fertilizer. Plant waste is usually rich in carbon, while animal manure waste contains a high nitrogen content. In the early stage of composting, mixing and stirring carbon-containing and nitrogen-containing wastes can effectively balance the carbon-nitrogen ratio and improve fermentation conditions. In order to accelerate the microbial decomposition process, it is often necessary to add an appropriate amount of functional bacterial agents. During the composting process, the temperature and humidity of the compost pile must be closely monitored, and ventilation and humidification must be carried out in time to promote microbial activity. Anaerobic and aerobic fermentation conditions must be adjusted in a timely manner at each stage of composting to ensure sufficient fermentation and improve the quality of compost.

[0003] At present, a domestic patent with authorization announcement number CN221955998U discloses a composting device, including a composting box and a top cover detachably arranged on the top thereof, a stirring shovel is arranged in the inner cavity of the composting box, a ring is arranged at the center of the top of the top cover, a rotating rod is rotatably connected inside the ring, a turntable is arranged at the top of the rotating rod, and a support rod is fixedly connected to the bottom end of the rotating rod, a connecting rod is arranged at the top of the stirring shovel, and the connecting rod is detachably connected to the support rod.

[0004] The above-mentioned composting device, when it is necessary to stir the fertilizer in the compost box, drives the rotating rod to rotate inside the ring by rotating the turntable, so that the supporting rod and the connecting rod at the bottom of the rotating rod rotate simultaneously with the stirring, so that the stirring shovel stirs the fermenting fertilizer inside the compost box.

[0005] Although the above-mentioned composting device has the advantages of being able to operate the stirring shovel externally to stir the fertilizer and reducing the frequency of opening the top cover during the composting process, the technical solution still has the following shortcomings:

[0006] In this technical solution, the fertilizer in the compost bin is stirred by a rotating stirring shovel. However, when the stirring shovel rotates, it can only achieve a good stirring effect on the fertilizer at the same height of the shovel surface; in the vertical direction, the stirring uniformity of the fertilizer is insufficient. Therefore, the above composting device has limited effect in achieving all-round and uniform stirring of the fertilizer in the compost bin. Summary of the invention

[0007] The object of the present invention is to provide a composting device to solve the technical problem mentioned in the background art that the existing composting device has limited effect in achieving all-round and uniform stirring of fertilizers in a composting box.
