Abstract

The invention provides an adjustable lifting device for a mini-tiller. A rotary tillage tool is installed on the side wall of a gearbox casing of the mini-tiller through a rotating shaft and can rotate around the rotating shaft of the gearbox casing to be adjusted. A support is fixed to the gearbox casing. One end of a lifting arm is installed on the support in a rotating mode through a center shaft, and the other end of the lifting arm is fixed to the rotary tillage tool so that the rotary tillage depth of the rotary tillage tool can be adjusted by rotating the lifting arm. A torque arm spring is arranged on the center shaft. The two ends of the torque arm spring are fixed to the gearbox casing and the lifting arm respectively so that falling impact force of the rotary tillage tool can be reduced by means of acting force of the torque arm spring. The requirements of users for different tillage depths of a rotary tiller can be met, and the different tillage depths can be adjusted. The adjustable lifting device is small, exquisite and simple in structure, and easy to operate. The torque arm spring is additionally arranged in the device, and can absorb vibration of the rotary tiller. The device can be used in cooperation with other agricultural implements.

Description

technical field [0001] The invention relates to a lifting device, in particular to an adjustable lifting device for a tiller. Background technique [0002] Micro tillage machinery is widely used in our country, especially in the southwest and some hilly areas. The tiller has the advantages of simple mechanism and convenient operation. However, the structure is small and the space that can be arranged is small is also a shortcoming of the current micro-tillage machinery. Because some structures of ordinary agricultural machinery cannot be directly arranged on the tiller due to the small space, in some respects, the operation of the tiller is not very convenient. Especially on some micro-rotary tillers, because the micro-tillers have requirements for the depth of tillage, in order to meet the deeper requirements, many manufacturers make the rotary tillers heavier, relying on the gravity of the rotary tiller itself to meet the requirements of the depth of tillage. Now There ...
