Description

TECHNICAL FIELD

[0001] The utility model relates to the field of agriculture, especially a kind of agricultural rotary tillage robot. BACKGROUND

[0002] In order to create better soil tillage structure and surface state in farming, on the one hand, the soil can be made soft by rotary tillage, which is more conducive to seedling and survival, and on the other hand, the soil can be improved by ridge work to improve the soil structure and increase the soil ventilation and water balance, so as to accelerate the activity of soil microorganisms and the decomposition and absorption of organic fertilizer.

[0003] The current rotary tillage robot mainly adopts two power modes, one is battery-powered pure electric power output mode, and the other is diesel power output mode using traditional tractor. The former can only cope with the greenhouse environment, and there is a power shortage in the field environment, and the electric power output can easily cause motor damage. The latter needs an additional operator, which can cause cost increase. SUMMARY

[0004] In view of the deficiencies of the prior art, the utility model aims to provide an agricultural rotary tillage robot, which uses a range-extending hybrid power mode instead of pure electric power to meet the demand of field rotary tillage.

[0005] To solve the above technical problems, an agricultural rotary tillage robot comprises a vehicle frame, characterized in that: a power module is arranged above the vehicle frame, the power module comprises an oil tank and a generator, a suspension bracket is arranged at the rear side of the vehicle frame, one end of the suspension bracket is fixed to the vehicle frame, and a rotary tillage rear hitch is arranged at the other end of the suspension bracket; the rotary tillage rear hitch comprises a protective cover, a rotary fixing frame and a rotary shaft, the rotary fixing frame is arranged in the middle of the protective cover, one rotary shaft is arranged at each side of the rotary fixing frame in the protective cover, and a rotary tillage knife is arranged on the rotary shaft.

[0006] A set of track wheels is arranged at each side of the vehicle frame.

[0007] A rotary tillage motor is further arranged at the rear side of the vehicle frame, the output end of the rotary tillage motor is connected to the rotary fixing frame, the top of the rotary fixing frame penetrates through the protective cover and is connected to the rotary tillage motor, and the bottom of the rotary fixing frame is connected to the rotary shaft.

[0008] A belt pulley is arranged in the rotary fixing frame, the belt pulley drives and connects the rotary tillage motor and the rotary shaft, one end of the rotary shaft close to the inner side is connected to the rotary tillage motor through the belt pulley, and the other end of the rotary shaft close to the outer side is rotationally connected to the protective cover.

[0009] A foldable baffle is arranged at the rear side of the protective cover.

[0010] According to this utility model, a range-extended hybrid power system is used to replace pure electric power to meet the needs of rotary tillage in the field; at the same time, since diesel power is used, a larger power motor can be replaced, avoiding the situation where the rotary tillage motor stops when it comes into contact with hard objects such as stones during the rotary tillage of the soil, thus improving the rotary tillage efficiency.
