Problems solved by technology

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, it will Cause the casing and its components to vibrate to a certain extent, which will have a certain adverse effect on the stability of the machine during work, but the existing shredders do not have such shock-absorbing equipment to solve this problem
In addition, in the existing shredders, the connection between the parts is usually rigid connection, which requires relatively high dimensional accuracy of the parts, resulting in higher manufacturing costs of the machine

Abstract

The invention relates to a shredder comprising a motor, a fan cover sleeved on the motor and an air outlet. The shredder also comprises a flexible connecting piece which is a plastic connecting pipe connected between an air guide opening and an air outlet of the fan cover. Thus, in such a way that a flexible connected pipe is connected between the air guiding opening and the air outlet of the shredder, the vibration generated when the motor works can be effectively absorbed, and the requirement on the size precision of connection between the air guiding opening and the air outlet is lowered.

Description

Technical field [0001] The present invention relates to a chipper. Background technique [0002] Among the garden tools, the shredder is usually used to chop leaves and small branches, etc. In the earlier period, the cutting work was carried out by driving the cutting tool to rotate through the induction motor. 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, it will Cause casing and parts thereof to produce certain vibration, produce certain bad influence to the stability of machine in work like this, and existing shredder does not have such shock-absorbing equipment to solve this problem. In addition, in the existing wood chippers, the connections between the components are usually rigid connections, which requires relatively high dimensional accura...
