[0002] A lawnmower is a mechanical tool used for trimming lawns and vegetation. It is widely used in home gardening, public green spaces, and agricultural planting. According to the cutting method, it can be divided into rotary lawnmowers, roller lawnmowers, and swivel lawnmowers. Among them, the roller lawnmower mainly consists of a drive mechanism, a transmission mechanism, and a cutting mechanism. The cutting mechanism mainly consists of a blade shaft and multiple blades fixed on the outside of the blade shaft.

[0003] When using a rotary lawnmower to mow the lawn, the blade shaft is usually driven by a transmission mechanism to rotate, which in turn rotates the blades to achieve the mowing. When the grass on the lawn is very moist, especially in the early morning, the blades often have water stains and grass clippings attached to their surface after mowing. This requires manual cleaning of the blades to prevent them from rusting. However, manual cleaning of the blades is not convenient because there are many blades, making it difficult to clean them quickly. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1-6 One embodiment of this utility model is a cleaning mechanism for a lawnmower blade, comprising a tractor 1 and a housing 2. The tractor 1 is fixedly connected to the rear end of the housing 2. A motor 4 is fixedly connected to one side of the housing 2. The drive end of the motor 4 passes through the inner wall of the housing 2 and is fixedly connected to a blade shaft 10. Multiple evenly distributed blades 9 are fixedly connected to the outer side of the blade shaft 10.

[0034] The motor 4 is started to drive the cutter shaft 10 to rotate. When the cutter shaft 10 rotates, it will drive the blade 9 to rotate. When the blade 9 rotates, it can cut the grass on the ground. At the same time, the tractor 1 is started to push the housing 2 and the cutter shaft 10 forward, so that the blade 9 can clean up the grass on the ground over a large area.

[0035] An electric guide rail 12 is fixedly connected to the top wall of the housing 2. The electric guide rail 12 has a built-in power supply, so that the electric guide rail 12 does not need an external power supply when it is running. A slider 15 is slidably connected inside the electric guide rail 12. A fixing ring 8 is fixedly connected to one side of the slider 15. A limit groove 17 is opened inside the fixing ring 8. A limit block 16 is slidably connected inside the limit groove 17. The limit groove 17 is a T-shaped structure. The limit block 16 is a T-shaped structure. A cleaning ring 14 is fixedly connected to one side of the limit block 16. The cleaning ring 14 is made of sponge material. A slot 13 is opened on one side of the cleaning ring 14. One side of the blade 9 is inserted into the slot 13.

[0036] The electric guide rail 12 drives the slider 15 to move the fixed ring 8. When the fixed ring 8 moves, it will drive the cleaning ring 14 to move to one side. Since the blade 9 is inserted into the slot 13, the cleaning ring 14 will clean the water stains and grass clippings on the outside of the blade 9 when it moves. At the same time, when the angle of the blade 9 changes, the cleaning ring 14 will make the limiting block 16 slide in the limiting groove 17 according to the angle of the blade 9, so that the blade 9 is always inserted into the slot 13 when the cleaning ring 14 moves.

[0037] A bellows 11 is fixedly connected to one side of the inner wall of the shell 2. A plurality of evenly distributed through holes 18 are opened on one side of the bellows 11. A pipe 5 is connected to the top of the bellows 11. One end of the pipe 5 passes through the shell 2 and is connected to an air pump 3. The air pump 3 is fixedly connected to one side of the top of the shell 2.

[0038] After the cleaning ring 14 has finished cleaning and resetting the blade 9, the air pump 3 can be started to generate suction in the pipe 5 to deliver air into the air box 11 and spray it out from the through hole 18 on the air box 11 to further clean the blade 9 on the cutter shaft 10 and prevent water stains from remaining on the blade 9.

[0039] A horn 6 is fixedly connected to both sides of the top of the tractor 1, and a light 7 is fixedly connected to the middle of the top of the tractor 1. When the tractor 1 pushes the housing 2 to move, the horn 6 can make a sound to remind the staff at the front of the tractor 1 to pay attention. When the tractor 1 pushes the housing 2 and the cutter shaft 10 to mow the lawn at night, the light 7 can illuminate the lawn in front of the tractor 1 so that the staff can see the condition of the lawn at night.

[0040] Working principle: The starting motor 4 drives the cutter shaft 10 to rotate. When the cutter shaft 10 rotates, it drives the blade 9 to rotate. When the blade 9 rotates, it can cut the grass on the ground. At the same time, the starting tractor 1 pushes the housing 2 and the cutter shaft 10 forward, so that the blade 9 can clean the grass on the ground over a large area. When the blade 9 has cut the grass, and there are water stains and grass clippings on the blade 9, the electric guide rail 12 can be started to drive the slider 15 to move the fixing ring 8. When the fixing ring 8 moves, it will drive the cleaning ring 14 to move to one side. Since the blade 9 is inserted into the slot 13, the cleaning ring 14 will clean the water stains and grass clippings on the outside of the blade 9 when it moves. At the same time, when the angle of the blade 9 changes, the cleaning ring 14 will make the limiting block 16 slide in the limiting groove 17 according to the angle of the blade 9, so that the blade 9 is always inserted into the slot 13 when the cleaning ring 14 moves.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
