[0002] A lawnmower is a mechanical tool used for trimming lawns, vegetation, etc. It consists of a blade disc, engine, wheels, walking mechanism, blades, handle, and control unit.

[0003] For example, Chinese Patent No. CN102668801B (Lawn Mower) includes a discharge deflector guard for a lawn mower having a cutting blade rotatably mounted within a cutting chamber, wherein the cutting chamber communicates with a discharge chute, and the discharge chute has a discharge chute outlet formed in the surface of the lawn mower and can be blocked by means of a closing flap; wherein the guard is adapted to be detachably attached to the lawn mower near the discharge chute outlet to enclose the outlet and thereby receive grass clippings in use, wherein the guard and the surface of the lawn mower form a substantially airtight / grass clipping-tight seal; and wherein the guard has an operable inner surface including a substantially vertical portion that forms a discharge orifice with the surface of the lawn mower and extends below the cutting height of the lawn mower. The present invention also describes a lawn mower having said guard.

[0004] However, most existing lawnmowers use electric motors to drive the blades, which consumes a lot of energy and requires moving back and forth between locations for a single cut, which is time-consuming and labor-intensive. Therefore, they do not meet the current needs. To address this, we have proposed a linkage mechanism between the lawnmower's wheels and the blades. Utility Model Content

[0005] The purpose of this utility model is to provide a linkage mechanism between the walking wheels and the cutting blades of a lawnmower, so as to solve the problems mentioned in the background art that most existing lawnmowers are driven by motors to rotate the cutting blades, which results in serious energy consumption and requires moving back and forth to one place for a single cutting operation, which is time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a linkage mechanism between a lawnmower's traveling wheel and a cutting roller, comprising: two traveling wheels, a protective baffle on one side of each traveling wheel, and a cutting assembly between the two protective baffles. The cutting assembly includes a first cutting roller and a second cutting roller. The first cutting roller includes a first cutting shaft, with gears at both ends of the first cutting shaft. The inner wall of the traveling wheel is provided with gear teeth, and the first cutting shaft is driven by meshing with the gear teeth.

[0007] Preferably, the outer wall of the first cutter shaft is provided with a first hob, and the first hob is welded and fixed to the first cutter shaft.

[0008] Preferably, the second hobbing cutter part includes a second cutter shaft, a second hobbing cutter is disposed on the outside of the second cutter shaft, and the second hobbing cutter is welded and fixed to the second cutter shaft. A timing belt is disposed between the first cutter shaft and the second cutter shaft, and the two ends of the timing belt are respectively sleeved on the first cutter shaft and the second cutter shaft. The first cutter shaft is linked to the second cutter shaft through the timing belt.

[0009] Preferably, the first hobbing cutter part further includes a first protective cover, and the first protective cover is located above the first hobbing cutter. The second hobbing cutter part further includes a second protective cover, and the second protective cover is located outside the second hobbing cutter. Both ends of the first protective cover and the second protective cover are provided with ball bearings, and the first cutter shaft and the second cutter shaft are rotatably connected to the first protective cover and the second protective cover respectively through ball bearings.

[0010] Preferably, a first limiting ring plate is provided on one side of the timing belt, and a second limiting ring plate is provided on the other side of the timing belt, and the timing belt is positionally limited by the first limiting ring plate and the second limiting ring plate.

[0011] Preferably, an auxiliary wheel axle is provided on one side of the mowing assembly, and auxiliary wheels are rotatably connected to both ends of the auxiliary wheel axle. A connecting frame is provided on one side of the auxiliary wheel.

[0012] Preferably, a connecting rod is provided on one side of the protective baffle, and the connecting rod is fixed to the protective baffle by external bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets gears at both ends of the first cutter shaft and sets gear teeth on the inner wall of the walking wheel. When the walking wheel rotates, the first cutter shaft is driven by the meshing of the gears and gear teeth, thereby driving the first cutter to rotate. The first cutter shaft and the second cutter shaft are connected by a timing belt. When the first cutter shaft rotates, the second cutter shaft is driven to rotate by the timing belt, achieving a linkage effect. The first cutter and the second cutter can perform two grass cutting operations on the same place without having to move back and forth, saving time and effort. In addition, the linkage method saves energy consumption and reduces grass cutting costs. It solves the problem that most existing lawnmowers drive the cutter to rotate by a motor, which causes serious energy consumption and requires moving back and forth to one place for a single grass cutting operation, which is time-consuming and labor-intensive.

[0015] (2) By setting a first guard and a second guard above the first and second rollers respectively, the first and second rollers are protected, and grass is prevented from flying upwards and injuring people when cutting grass, thus improving safety. Attached Figure Description
