Direct-current rotary cultivator

Abstract

The invention relates to a direct-current rotary cultivator comprising a frame, a driving device supported by the frame, a cultivating device connected with the driving device through a transmission device, and a control device electrically connected with the driving device and the transmission device; wherein the frame comprises a machine body, a resistance rod and an armrest assembly; the driving device comprises a direct-current motor and a battery pack; the transmission device comprises a first transmission device and a second transmission device, and is connected with the cultivating device through a transmission shaft connected with the second transmission device; the cultivating device comprises a knife rest assembly and a rotary cultivating knife assembly; and the battery pack is arranged between the knife rest assembly and the axle line direction of the armrest assembly. The direct-current rotary cultivator has the advantages of small volume, high efficiency, long service life, easiness, convenience and safety for operation, and uniform cultivated soil particles, and has the functions of self-protection and early warning.

Description

technical field [0001] The invention relates to a tiller, in particular to a direct current rotary tiller used in the fields of gardening and agriculture. Background technique [0002] In the currently disclosed prior art, the rotary tiller can be divided into two types according to different powers, one is a rotary tiller powered by a fuel engine, and the other is an electric rotary tiller. [0003] Since the fuel engine type rotary tiller has many problems such as high cost of use, high noise, unfriendly emissions, difficulty in starting the engine, etc., it is gradually replaced by the electric rotary tiller. [0004] Electric rotary tillers can be divided into AC motor rotary tillers and DC motor rotary tillers according to different types of power sources. [0005] Rotary tillers with AC motors require an external power supply. For rotary tillers that are mostly used outdoors, the power is not stable, it is inconvenient to use, and there are potential safety hazards. ...

AI Technical Summary

Problems solved by technology

[0008] In the rotary tillers currently on the market, the operating armrest cannot be adjusted up and down, left and right, making it impossible for different users to maintain a most comfortable state of operation; in addition, the function of the resistance bar is single, and the rotary blade components are integrated type, and there is only one fixed speed, which cannot adapt to the needs of different soil properties. At the same time, the operator cannot control the left and right plowing depths to keep the same when the rotary tiller is plowing, thus reducing the work efficiency.
