Deep ploughing rotary cultivator

Abstract

The invention provides a deep ploughing rotary cultivator, and relates to the technical field of rotary cultivators, the deep ploughing rotary cultivator comprises a rotary cultivator shell, a deep ploughing mechanism is installed in the rotary cultivator shell, the deep ploughing mechanism comprises a deep ploughing transmission shaft, and one end of the deep ploughing transmission shaft is rotatably provided with a first rotating disc; the first rotating disc is rotatably mounted in a first rotating disc mounting groove formed in the inner wall of the rotary cultivator shell, the first rotating disc is connected with the control mechanism, the control mechanism comprises a shell, the shell is fixedly mounted on the surface of one side of the rotary cultivator shell, and a worm can rotate by starting a control motor; the first rotary disc can be driven to rotate by taking the center of a first rotary disc mounting groove as a circle, and the second rotary disc is driven to rotate synchronously through a plurality of connecting columns, so that the deep ploughing transmission shaft and a plurality of deep ploughing blades are driven to rotate synchronously, and the positions of the deep ploughing transmission shaft and the deep ploughing blades are changed. The tillage depth is convenient to adjust, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of rotary tillers, in particular to a deep-plow rotary tiller. Background technique [0002] A rotary tiller is a cultivating machine that is matched with a tractor to complete plowing and harrowing operations. It is mainly used to break the soil on the surface and the roots of plants. For example, a deep-plow rotary tiller proposed by the patent application number CN201710210450.7, which includes: The hitch box, and the transmission box connected to the hitch box, the transmission box includes a connection end connected to the hitch box, and a rotary tiller extending away from the hitch box through the connection end, the transmission box A rotary tiller shaft is arranged on the rotary tiller end of the rotary tiller, and a rotary tiller knife group is arranged on the rotary tiller shaft, and the rotary tiller knife group rotates along the circumferential direction of the rotary shaft; The plowing shaft ex...

AI Technical Summary

Problems solved by technology

[0003] But the above-mentioned technical scheme, when using, due to the thickening of the tillage soil layer, the contact area between the rotary tiller and the soil layer gradually increases, which requires a larger driving force to drive, which will increase the work of the drive and transmission mechanism of the rotary tiller. load, resulting in a reduction in the service life of the equipment, the tillage depth of the rotary tiller is limited during cultivation, and the soil layer cannot be deeply cultivated, so we make improvements to this and propose a deep-plow rotary tiller
