The research of domestic organic manure turning machine started relatively late, and most of them copied foreign models. The product design mainly relied on experiments and experience, and lacked of theoretical research on turning and throwing machine. The existing problems were mainly manifested in poor walking safety, reliability of turning and throwing system and adaptability to composting materials. At the same time, there are some deficiencies in the arrangement and distribution of throwing knives and the degree of automation.

Sinochem Huafeng company, affiliated to the Chinese Academy of agricultural machinery, has developed the first professional tipping machine in China, which is at the leading level in the domestic composting treatment and organic fertilizer processing equipment industry. It optimizes the design and distribution of the paddle type tipping gear of the tipping machine. The impact vibration is small during operation. It has the functions of milling, crushing, stirring, tipping and transferring materials. At the same time, a hydraulic lifting rotor is designed, which can start working at any position.

Research and development in the field of organic fertilizer turning machine treatment equipment are relatively fast abroad, with Germany and the United States being the most prominent. Its compost tipping equipment integrates multiple functions, has an intelligent operation mode and a comfortable driving environment, and is developing in the direction of specialization, large-scale and intelligence. The equipment has four characteristics in detail design. ① Single lever operation: similar to the operation of helicopters, it can complete the forward, backward and flip of equipment with one hand. ② Cab: equipped with air conditioning, air filtration and purification system, good working environment, first-aid kit, and operation logo is pattern logo for easy operation. ③ Track Cleaner: in the process of traveling, it cleans the materials at the lower end of the triangular strip stack and gathers them in the middle, so as to save land, reduce resistance and reduce energy consumption. ④ Crawler walking: compared with the wheel type, the contact area of the crawler is large, and there are anti-skid gaskets to ensure the stable operation of the equipment. It has a professional equipment maintenance team, and vulnerable parts can be simply removed and replaced, which can be localized.
