Description

Technical Field

[0001] The utility model relates to the field of tilling machines, in particular to a tilling machine with adjustable rotary tillage depth. Background Art

[0002] A tiller is a mechanical device used in agricultural operations. Its main functions include tilling, turning the soil, preparing the land, and sowing. Tillers can be divided into different types, including wheeled tillers, rotary tillers, and disc tillers. The working principle of a tiller is to use the tillage mechanism to till and plow the soil, loosen the soil, turn it over, and deep plow it. When the transmission drives the tillage blade or the knife disc to rotate, the soil will be cut, turned over, and mixed, realizing the function of the tiller.

[0003] After searching, the applicant found that a Chinese patent disclosed "a tilling machine with adjustable tillage depth", and its publication number is "CN207476145U". This patent mainly realizes the function of adjusting the tillage depth by controlling the extension of the tillage knife according to the needs under the action of the gear, rack and connecting rod, which is conducive to sowing seeds with different burying depths and meeting different tillage requirements. The rotary cutting knife can remove the grass around the tillage machine without the use of other equipment. It has the function of tilling and weeding at the same time, which reduces labor. Moreover, the distance between the knife holders can be adjusted by the fixed ring, so as to adjust the spacing of the ridges according to the needs, which is conducive to land cultivation and meets the cultivation requirements of users.

[0004] The device in the above patent can adjust the depth of cultivated land to a certain extent, but in reality, due to the different hardness of the soil in each piece of land, the land needs to be tilled to different degrees. When encountering hard land, a tilling machine with a larger spacing between tilling blades is needed to first till the large pieces of soil and then fine tillage. If the tilling blades are not replaced, the tillage depth cannot be reached. If they are replaced, the time for tilling the land will be delayed. Utility Model Content

When encountering hard land, a tilling machine with a larger spacing between tilling blades is needed, so that large pieces of soil can be tilled first, and then fine tillage can be carried out. If the tilling blades are not replaced, the tillage depth cannot be reached, and if they are replaced, the tillage time will be delayed.
