[0002] Organic fertilizer generally refers to fertilizer made from animal excrement or plant residues as raw materials, which are fermented and decomposed, and then processed into granules through various equipment for easy storage and use. The fermentation of organic fertilizer is usually done by mixing animal excrement or plant residues containing fertilizer ingredients with soil and minerals, and then mixing and piling them under high temperature and humid conditions, through fermentation and decomposition by microorganisms. During the composting process, the compost raw materials generally need to be turned over every few days. Common turning operations are generally completed using a compost turning machine.

[0003] The patent website discloses a new type of crawler compost turner (publication number: CN217868674U), including a compost turner body, the compost turner body is a door frame type structure, an engine for providing power is arranged on the compost turner body, the output end of the engine is connected with a compost turning power output universal joint and a walking output universal joint, the output end of the compost turning power output universal joint is connected with a compost turning shaft for turning and throwing materials, a stacker for stacking is arranged at the front end of the compost turner body, an adjusting mechanism for adjusting the width of the stacking is installed on the stacker, the adjusting mechanism includes an adjusting plate connected to the front separation surface by a hinge, a connecting plate is fixedly arranged on the inner side surface of the adjusting plate, a plurality of holes are arranged on the connecting plate, and connecting bolts for connecting the connecting plates together are arranged in the holes, which has the advantages of not only being able to adjust the width of the stacking, but also being easy to install and use.

However, when the stirring blades are damaged, the stirring blades need to be re-welded in the turning shaft, which brings inconvenience to the work. Long-term welding also reduces the service life of the turning shaft, so there is room for optimization. Utility Model Content
