Abstract

A mowing machine comprises a power head and a cutting head (9). The power head comprises a power driving device (4), an upper tube (2), and a control handle (1). The power driving device (4) is connected to the control handle (1) by the upper tube (2). The power driving device comprises a driving motor (7) and a gearbox (8) that are disposed in a casing (6). The power driving device has one end connected to the upper tube (2) and the other end detachably connected to a lower rod (5). The lower rod (5) is connected with a cutting head (9). In the mowing machine, the cutting head is directly connected to the gear shaft rather than the internal transmission shaft, and the main handle is connected by using a tube, so that flexible shaft transmission is avoided, thereby providing a good overall balance. The mowing machine provides good user experience, features a low cost, reduced shaft loss and improved working efficiency, and can effectively solve the problems of large noise and violent vibration at the connection of the upper and lower rods.

The main structure of the lawnmower is divided into the motor front and the motor rear. Compared with the current motor front and motor rear structure, the motor center structure may cause uneven weight distribution of the grass machine and the problem of top-heavy weight. .

At present, the existing mid-mounted lawnmower in the market uses a motor motor with a gear box, and powers the lower rod (grass head end) through a flexible shaft, and the motor and the PCB board are located in a long and narrow main handle.

In addition, the center mower also uses the motor in the middle of the whole machine, and the main handle is connected by a pipe, and the motor is connected with a flexible shaft and then connected to the lower rod (the head end).

However, the above two mid-mounted lawnmower structures have poor overall balance, and the user feels uncomfortable during use, has a complicated structure, high manufacturing cost, large shaft loss, low work efficiency, and there is also a connection between the upper and lower rods. The segment noise is large and the vibration is large.

Utility model content

The technical problem mainly solved by the utility model is to provide a middle lawn mower with reasonable layout, high efficiency, small vibration and small noise influence.

In order to solve the above technical problem, a technical solution adopted by the present invention is to provide a center mower, comprising: a power head and a grass head, the power head including a power driving device, an upper tube and a control handle. The power driving device and the control handle are connected by the upper pipe, and the power driving device comprises a driving motor and a gear box which are assembled in a casing, and the output end of the driving motor and the gear box Connected, the output end of the gearbox is detachably connected to the lower rod, and the grass head is connected to the lower rod.

In a preferred embodiment of the present invention, the power driving device and the lower rod are detachably connected by a quick change device.

In a preferred embodiment of the invention, the quick change device is a pipe clamp device integrated on the gearbox.

In a preferred embodiment of the present invention, the upper tube is provided with an auxiliary handle.

In a preferred embodiment of the present invention, the drive motor transmits the power output to the grass head after being decelerated by the gear box.

In a preferred embodiment of the present invention, the drive motor, the gear box and the grass head are electrically connected to the control handle.

The utility model has the beneficial effects that the middle lawn mower of the utility model does not pass through the built-in transmission shaft, and the gear shaft directly connects the grass head, and also connects the main handle through a pipe, which is reduced compared with the prior art. A flexible shaft transmission makes the whole balance is very good. The user feels comfortable during use, saves cost, reduces shaft loss, improves work efficiency, and can effectively solve the problem of large noise and large vibration of the connecting section of the upper and lower rods. .
