[0007] A first mounting hole is provided on the top cover and a supporting rib is provided in the first mounting hole;

[0008] The door cover is arranged in a first mounting hole adapted to its shape and its bottom is in contact with the supporting edge;

[0009] The front cover is movably connected to the top cover.

[0010] Furthermore, the door cover is fixed with symmetrically distributed rotating shafts, and one end of the rotating shaft is rotatably connected to the top cover.

[0011] Furthermore, the top cover is provided with a through hole allowing the engine oil inlet pipe to pass through.

[0012] In the above solution, after the oil inlet pipe of the engine passes through the through hole, refueling can be conveniently performed to ensure the normal operation of the lawn mower.

[0013] Furthermore, a second mounting hole for mounting a warning light is provided on the top cover.

[0014] The above solution can make a sound during the day and a sound at night by installing a warning light to remind people around to stay away from the lawn mower, thereby ensuring personal safety during the operation of the lawn mower.

[0015] Furthermore, heat dissipation holes are provided on the door cover.

[0016] Furthermore, a dustproof net is movably provided in the heat dissipation hole.

[0017] In the above solution, when the door cover is closed, the heat generated by the electrical components in the lawn mower during operation can be discharged to the outside through the heat dissipation holes, and the dustproof net can effectively reduce the probability of dust entering the lawn mower through the heat dissipation holes.

[0018] Furthermore, the door cover and the top cover are connected via a telescopic tongue lock.

[0019] The above solution can lock the position of the door cover after it is closed by using the telescopic cam lock, thereby preventing the door cover from fluctuating up and down during the movement of the lawn mower. At the same time, the unlocking operation before the door cover needs to be opened is quick and convenient.

[0020] Furthermore, the front cover and the top cover are connected by screws.

[0021] Furthermore, a handle is provided on the door cover.

[0022] The above solution makes it easier to open and close the door cover by providing a handle.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] Compared with the existing technology, this device can greatly reduce the probability of dust entering the interior of the lawn mower and causing dust accumulation in the air filter by arranging a dust cover in the upper area of ​​the lawn mower. The air circulation is smooth and the engine fuel burns fully without any adverse effects. There is no need for frequent maintenance of other components, and the dust prevention effect is good.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0031] like Figures 1 to 3 As shown, a protective device for a lawn mower includes a dust cover fixedly arranged in the upper area of ​​the lawn mower, the dust cover includes a top cover 1, a door cover 2 and a front cover 3.

[0032] A first mounting hole 11 is formed on the top cover 1 and a supporting rib 12 is provided in the first mounting hole 11;

[0033] The door cover 2 is placed in the first mounting hole 11 that matches its shape and its bottom contacts the supporting edge 12;

[0034] The front cover 3 is movably connected to the top cover 1 (the front cover 3 and the top cover 1 are connected by screws).

[0035] Further refinement of the embodiment of the present invention is as follows: Figure 2 and Figure 3 As shown, the door cover 2 is fixed with symmetrically distributed rotating shafts 21, and one end of the rotating shaft 21 is rotatably connected to the top cover 1 through a bearing.

[0036] Further refinement of the embodiment of the present utility model, Figure 1 As shown, the top cover 1 is provided with a through hole 13 allowing the engine oil inlet pipe to pass through.

[0037] Further refinement of the embodiment of the present utility model, Figure 1 and Figure 3 As shown, the door cover 2 is provided with heat dissipation holes 22;

[0038] As a further optimization of the above embodiment, a dustproof net is movably provided in the heat dissipation hole 22; the dustproof net is not shown in the figure.
