Branch crushing machine

Abstract

A branch crushing machine comprises a motor component, a hobbing-cutter component driven by the motor component and a transmission component connected between the motor component and the hobbing-cutter component. The motor component comprises a series excited machine and a motor output axis; the hobbing-cutter component comprises a cutter axis and a hobbing-cutter mounted on the cutter axis; the transmission component comprises a belt wheel transmission part and a reduction gearbox matched and connected with the belt wheel transmission part; the belt wheel transmission part is matched and connected with the motor output axis; the reduction gearbox is connected to the hobbing-cutter component; and the axial line of the motor output axis is approximately parallel to that of the cutter axis,thus reducing the length dimension of the motor in axial line direction, compacting the structure and reducing package size.

Description

Technical field [0001] The invention relates to a branch shredder. Background technique [0002] In garden tools, a branch shredder is usually used to shred leaves and small branches, etc., which generally use an induction motor to drive a cutting tool to rotate at a high speed to perform cutting work. In addition, a gearbox is directly installed between the induction motor and the output shaft of the cutting tool. Therefore, the motor axis and the output shaft of the cutting tool are roughly on the same straight line, which makes the length of the entire machine in the direction of the motor axis longer. The structure is not too compact, which greatly increases its packaging size. [0003] Since then, a shredder with a series motor has appeared on the market. The induction motor is replaced by a series motor, because the series motor has a lower manufacturing cost. However, due to the higher speed of the series motor, the The branch machine needs to be equipped with a good noise...

AI Technical Summary

Problems solved by technology

In addition, a reduction box is directly installed between the induction motor and the output shaft of the cutting tool, so the axis of the motor and the output shaft of the cutting tool are generally located on the same straight line, so that the length of the entire machine in the direction of the axis of the motor is longer. Less compact structure greatly increases its package size

[0003] Since then, a shredder equipped with a series-excited motor has appeared on the market, and the induction motor is replaced by the series-excited motor, because the series-excited motor has a lower manufacturing cost, but due to the higher speed of the series-excited motor, the shredder The branch machine needs to be equipped with a good noise reduction and cooling mechanism to meet the requirements. However, the branch chippers with series-excited motors on the market currently use a constant power circuit board to control the speed of the motor. Have a good cooling mechanism to cool the working motor, which is extremely unfavorable to the use of the motor
