There are many mountainous and hilly areas in China, and large-scale farming machines cannot enter the mountainous areas, and even if they enter, they cannot cultivate in the mountainous and hilly areas. Therefore, rotary tillers are widely used in agricultural cultivation in these areas. But the plowing depth of existing rotary tiller is generally at 12-20cm. If things go on like this, the thickness of the mellow soil layer will decrease, which will cause the land to be shallow, and a hardened plow bottom layer will be formed under the shallow plow layer, which will affect the root system of the crops and make it difficult for water and fertilizer to infiltrate. At the same time, the arrangement of the rotary tillage working parts of these rotary tillage machines will also bring certain potential safety hazards to the operators who operate the deep tillage machines. Moreover, with the improvement of the level of mechanization, the cost of purchasing agricultural machinery is also increasing year by year.

The hydraulic rod is connected to the hydraulic oil tank through the oil circuit. , the front end of the piston rod of the hydraulic rod is connected with the connecting bracket of the deep tillage device; the composition of the deep tillage device includes a cross-shaped central support, the central support is connected with the connecting bracket of the deep tillage device, and the front end of the central support is provided with a driving wheel and a bearing seat of the driving wheel Fixed on the mounting bracket, there is a driven wheel at the end of the center bracket, and a support wheel at the upper and lower ends of the center bracket. The bearings of the driven wheel and the support wheel are fixed on the center bracket. There is a ring-shaped chain outside the wheel, and a chain knife is arranged on the chain; the power output end of the engine is connected with the power input end of the speed change mechanism, and the power input end of the driving wheel and the crawler walking device are respectively connected with the power output end of the speed change mechanism .

The chain knives are in a staggered structure. Chain knives are designed at an angle, with a sharp edge on one side of the knife and a blunt edge on the other. Under the control of the console, the forward and reverse of the chain can be realized. The design method of the angle of the chain knife and the use of the conversion handle can realize the functions of deep plowing and ditching respectively. Moreover, two adjacent chain cutters are arranged in a staggered manner, which is beneficial to reducing the impact and vibration caused by the crawler-type chain-type deep cultivator when it is working, so that the deep-cultivator runs smoothly during the working process.

Due to the adoption of the above technical scheme, the utility model uses the crawler belt traveling device as the mobile device, and installs the deep plowing device at the central position of the crawler belt traveling device, which not only simplifies the structure, but also ensures the operating safety of the operator. The crawler belt traveling device has better Terrain adaptability, and has good anti-skid ability. While the crawler is moving, the soil is plowed down from the surface soil, and the deep tillage device can adjust the inclination angle of the chain knife through the oil cylinder to obtain different angles of inclination to press into the soil. The structure can plow the soil deeply, thicken the soil plow layer, solve the problems of shallow plow layer, break the plow layer formed under the plow layer, affect the root system of crops, and make water and fertilizer infiltration difficult, etc., and can achieve the function of one machine with multiple functions , Save farmers' purchase costs. The utility model has the advantages of simple structure, low cost and ideal use effect.
