A plug-in electric rotary tiller

Abstract

The invention relates to a plug-in electric rotary tiller, which includes a rotary tiller body, a rotary tiller roller knife, a roller knife shaft assembly, a suspension rod, a reducer assembly, an electric control box and a rotary tiller circuit assembly. The circuit assembly of the rotary tiller includes the electrical interface part, the tool operation management part and the tool drive part. The electrical interface part quickly and reliably connects the power transmission cable between the rotary tiller and the electric tractor through the multi-contact electrical connector, so that the circuit assembly of the rotary tiller is connected to the complete power grid of the electric tractor. Realize the transmission of electric energy and data between the tractor and the rotary cultivator; the operation management part of the implement controls the power-on start, implement drive, power-off shutdown, high-voltage power safety management, implement operating status monitoring, and electrical interface connection process of the rotary tiller, etc. Carry out coordination and management; the drive part of the implement receives instructions from the management and control unit of the rotary tiller, controls the drive motor to output the corresponding electromagnetic torque, and drives the rotary tiller to perform operations.

Description

technical field [0001] The invention relates to the field of tillage machinery, in particular to a plug-in electric rotary tiller. Background technique [0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. The rotary tillage machinery used in traditional agricultural production is driven by a diesel engine through a series of transmission devices and a standard mechanical PTO interface. This driving method makes it difficult for the rotary tiller to get rid of the influence of the engine speed, which means that The working speed of the rotary tiller is limited to several isolated speed points, and it is difficult to realize stepless speed regulation; in the traditional mechanical power transmission mode, in order to realize the soft combination of the blade of the rotary tiller when it enters the soil to reduce the impact on the blade and The impact of the engine is generally realized by controlling the sl...

The rotary tillage machinery used in traditional agricultural production is driven by a diesel engine through a series of transmission devices and a standard mechanical PTO interface. This driving method makes it difficult for the rotary tiller to get rid of the influence of the engine speed, which means that The working speed of the rotary tiller is limited to several isolated speed points, and it is difficult to realize stepless speed regulation; in the traditional mechanical power transmission mode, in order to realize the soft combination of the blade of the rotary tiller when it enters the soil to reduce the impact on the blade and The impact of the engine is generally realized by controlling the slipping of the clutch, which not only wastes resources, but also has poor operation continuity and low operation efficiency; the power output interface of the traditional rotary tiller is a spline connection. The process is relatively complicated
