Description

An electric pruning machine

technical field

The utility model relates to an electric tool, in particular to a pruning machine capable of pruning branches of fruit trees and harvesting sugarcane.

Background technique

Existing electric fruit tree pruning machines are mainly used for branches of trees, branches and leaves of flowers, bonsai, etc. It generally adopts a scissors-type blade structure, and the motor is directed by a drive circuit. The motor drives the pot teeth through the planetary gear, and the pot teeth transform into a sector The size of the fan-shaped tooth opening drives the blade opening size. Due to the limited internal space of the pruning machine, the size of the fan-shaped tooth rotation is limited, which leads to the small opening of the blade of the existing electric fruit tree pruning machine, which makes it difficult to prune the larger diameter. Branches, the scope of application is relatively small, especially the thicker sugar cane, etc., this kind of structure is just not competent.

A nut, the nut is fixedly connected with a blade facing the iron hook, and the controller is provided with a clutch module, when the button is pressed, the clutch module controls the blade to extend out of the blade shell, and when the button is loosened, When the button is turned on, the clutch module controls the blade to shrink in the blade housing.

A connecting sleeve is fixedly installed on the front end of the housing, the rear end of the blade housing is fixedly connected to the front end of the connecting sleeve, and the rear end of the connecting sleeve is fixedly connected to the front end of the motor.

The rear end of the connection sleeve is provided with a plug-in fixing ring embedded in the housing.

The rotating shaft of the motor is connected with the rear end of the screw rod through a coupling, and a bearing is installed between the connecting sleeve and the coupling.

The nut is fixedly connected with a nut fixing seat, and the nut fixing seat is fixedly connected with the rear end of the blade.

The beneficial effects of the utility model are: a motor, a controller electrically connected to the motor and a rechargeable battery are installed in the housing of the utility model, buttons are arranged on the surface of the housing, a blade housing is installed on the front end of the housing, and the front end of the blade housing is fixed An iron hook is installed, the shaft of the motor is connected with a screw, and a nut is threaded on the screw, and the nut is fixedly connected with a blade facing the iron hook. The controller is equipped with a clutch module. When the button is pressed, the clutch module controls the blade to extend out of the blade. Outside the shell, when the button is released, the clutch module controls the blade to shrink in the blade shell. When pruning, just hook the iron hook on the branch and press the button. The operation is simple and easy to use. The screw and nut meshing transmission has Large output torque, so cutting is more convenient and labor-saving.
