Description

lawn mower

technical field

The utility model relates to a lawn mower.

Background technique

As known in the prior art, lawn mowers are particularly useful in building golf course lawns, and the lawn trimming of golf courses requires strict trimming effects to ensure consistent trimming of the entire lawn. These lawn mowers are generally manual Push lawn mowers, or riding lawn mowers.

Lawn mowers generally use rotary lawn mowers. Due to the stringent requirements of golf course grass and the lack of domestic market, most domestic golf courses purchase expensive imported lawn mowers.

However, imported lawn mowers are often used and require an operator to activate a control lever that is separated from the handle. The control lever activates the tensioner wheel to press the transmission belt to drive the driven wheel to rotate by increasing friction. This complicated operation method may cause Improper cutting performance will cause a lot of wear and tear on the conveyor belt.

Therefore, it is desirable to provide a lawn mower that is easy to operate and less damaging to the machine itself.

Contents of the invention

The purpose of the utility model is to provide a lawn mower with compact structure, simple operation and less damage to the machine itself.

In order to achieve the above-mentioned purpose, the technical solution of the utility model is a lawn mower, comprising:

case;

walking wheels, supporting the housing;

a drive assembly including a motor mounted on the housing, the motor having an output shaft capable of providing power;

The driven assembly includes a first hob and a second hob installed at the lower end of the casing;

Transmission assembly, including the driving wheel connected with the output shaft through the clutch and the driven wheel driving the driven assembly to move;

The operating lever is installed at the rear end of the casing, and is used to control the stop and start of the engine and the direction of the road wheels.

Further, the clutch includes a casing connected to the driving wheel, a shoe block located in the casing, and a friction plate placed on the inner wall of the casing, the shoe blocks are three and arranged uniformly along the circumferential direction, and adjacent A spring is connected between the two shoe blocks.

Further, the first hob is a worm gear hob, and the second hob is a gear hob.

Further, both ends of the first hob are provided with limiting brackets connected to the housing.

Further, the center of the clutch is connected to the output shaft of the engine, and its back is connected to the driving wheel.

Further, the driven wheel is connected to a transmission rod, one end of the transmission rod is connected to the first hob through a chain, and the first hob is connected to the second hob through a chain.

The beneficial effects of the utility model are:

The utility model controls the operation of the lawnmower by replacing the traditional compression wheel with the clutch, which reduces the operation steps and protects the conveyor belt by reducing friction. The utility model adopts the first hob and The structure of the second hob, and the first hob can be adjusted up and down using the limit device, which increases the accuracy of mowing. It can be well adapted to various terrains for the harsh conditions of the golf course, and has good promotion value. .

Description of drawings

Fig. 1 is the structural representation of the utility model.

Among the figure, 1 housing, 2 traveling wheels, 3 first hobs, 4 second hobs, 5 operating rods, 6 limit brackets, 11 driving wheels, 12 driven wheels, and 13 transmission rods.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

The following descriptions of the preferred embodiments are illustrative only, and are not intended to limit the application or use of the present invention.

A lawn mower is shown, comprising:

shell 1;

Walking wheels 2, supporting the housing 1;

A drive assembly, including an engine installed in the housing 1, the engine has an output shaft that can provide power;

The driven assembly includes a first hob 3 and a second hob 4 installed at the lower end of the housing 1;

The transmission assembly includes a driving wheel 11 connected to the output shaft through a clutch and a driven wheel 12 that drives the driven assembly to move;

Operating lever, is installed in the rear end of housing 1, is used for controlling the stop and start of engine and the direction of road wheel.

The clutch includes a casing connected to the drive wheel by welding, a shoe located inside the casing, and a friction plate placed on the inner wall of the casing. A spring is connected between the adjacent two shoe blocks.

The first hob 3 is a worm gear hob, and the second hob 4 is a gear hob.

Both ends of the first hob 3 are provided with limit brackets 6 connected to the housing.

When in use, the engine drives the clutch through the output shaft to combine the shoe of the clutch with the friction plate to drive the casing to move, thereby driving the driving wheel 11 connected to it to rotate, and the driving wheel 11 drives the driven wheel 12 through the transmission belt, and the driven wheel 12 Connected with the transmission rod 13, one end of the transmission rod 13 is connected with the first hob 3 through a chain, and the first hob 3 is connected with the second hob 4 through a chain, thereby driving the first hob 3 and the second hob 3 Hob 4 rotates.

The above description is only the preferred implementation mode of this patent. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of this patent, some improvements and replacements can also be made. These improvements and replacements It should also be regarded as the scope of protection of this patent.
