[0002] A disc mower blade is a piece of mechanical equipment used in agriculture and garden care, primarily for cutting grass, shrubs, and other crops;

[0003] In actual use, the existing disc mower blades can easily cause the cut grass to splash everywhere, thus polluting the surrounding environment.

[0004] The existing patent (publication number: CN213938899U) is a hand-held disc mower. When mowing, the power module drives the rotating shaft to rotate through a belt drive, thereby driving the disc to rotate to achieve mowing. The grass enters the protective cover, and the cut grass is blocked by the protective cover and cannot splash outward, thereby maintaining the overall environment of the mowing operation area.

[0005] In view of the above problems, the existing patents provide solutions, but they still have certain limitations, namely, the grass clippings blocked by the protective cover will adhere to the surface of the blade disc, thereby affecting the heat dissipation of the blade disc, and the accumulation of grass clippings may cause the blade disc to get stuck, which requires frequent maintenance or replacement of the blade disc, thus seriously affecting the mowing efficiency. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 5 , the utility model provides a technical solution:

[0031] A disc mower cutter comprises a body 1, a handrail 2 is fixedly mounted on the side wall of the body 1, a motor 3 is fixedly mounted on the top wall of the body 1, a cutter disc 4 is detachably mounted on the output end of the motor 3, and blades 5 are evenly fixedly mounted on the cutter disc 4;

[0032] The cleaning component comprises a protective cover 6 detachably mounted on the bottom wall of the vehicle body 1 , the bottom wall of the vehicle body 1 is provided with a brush plate 7 , and cleaning bristles 8 cooperating with the blade disc 4 are fixedly mounted on the bottom wall of the brush plate 7 .

[0033] During use, the user can start the motor 3 first, and then push the vehicle body 1 through the armrest 2, and the cutter disc 4 is driven to move during the movement of the vehicle body 1. At the same time, the motor 3 drives the blade 5 to rotate through the cutter disc 4 and perform a grass-cutting operation. Since the blade 5 rotates at a high speed, it is easy to cause grass fragments to fly everywhere, and then some of the grass fragments will hit the protective cover 6 and rebound to the surface of the cutter disc 4. At this time, the cutter disc 4 drives the grass fragments to gradually pass through the cleaning hairs 8 during the rotation, and then the grass fragments on the surface of the cutter disc 4 are cleaned under the action of the cleaning hairs 8, thereby effectively preventing the grass fragments from covering and affecting the heat dissipation effect of the cutter disc 4 and accelerating the wear of the cutter disc 4, thereby extending the service life of the cutter disc 4.

[0034] Specifically, Figure 2 , Figure 3 As shown, a limit rod 9 is vertically slidably installed on the bottom wall of the vehicle body 1, a mounting plate 10 is fixedly installed on the bottom end of the limit rod 9, and the brush plate 7 is detachably installed on the bottom wall of the mounting plate 10, and a spring 11 is fixedly installed between the top wall of the limit rod 9 and the bottom wall of the vehicle body 1.

[0035] A first push block 12 is fixedly mounted on the bottom wall of the brush plate 7, and the bottom wall of the first push block 12 is an inclined surface. A second push block 13 cooperating with the first inclined block is fixedly mounted on the top wall of the cutter disc 4.

[0036] A telescopic tube 14 is fixedly mounted between the top wall of the mounting plate 10 and the bottom wall of the vehicle body 1 , and the spring 11 is located inside the telescopic tube 14 .

[0037] By adopting the above technical solution, in the initial state, the spring 11 is in a freely extended state, and drives the second push block 13 to rotate during the rotation of the cutter disc 4, and then gradually contacts the inclined surface of the first push block 12 during the rotation of the second push block 13, and applies thrust to the inclined surface of the first push block 12, and then under the action of the thrust, the first push block 12 drives the brush plate 7 and the mounting plate 10 to move upward and squeeze the spring 11, when the second push block 13 is out of contact with the first push block 12, the spring 11 stretches and drives the brush plate 7 to reset through the mounting plate 10, that is, during the operation of the cutter disc 4, the brush plate 7 can be driven to shake through the second push block 13, and then the bristles can be driven to shake during the shaking of the brush plate 7, and the grass clippings adhered to the bristles gradually break away from contact with the bristles during the shaking of the bristles, thereby improving the cleaning effect of the bristles.

[0038] At the same time, by providing the telescopic tube 14, the spring 11 can be isolated from the outside world, thereby effectively preventing grass clippings from adhering to the surface of the spring 11 and affecting the normal expansion and contraction of the spring 11, thereby ensuring the normal operation of the device.

[0039] Specifically, Figure 3 , Figure 5 , Figure 6 As shown, a water tank 15 is fixedly mounted on the top wall of the vehicle body 1, a pressure valve 16 is fixedly mounted on the bottom wall of the water tank 15, a water pipe 17 is fixedly mounted on the output end of the pressure valve 16, and a water spray plate 18 is fixedly mounted on the bottom wall of the vehicle body 1, a cavity 19 is formed on the water spray plate 18, water spray holes 20 are evenly formed on the bottom wall of the cavity 19, and one end of the water pipe 17 away from the water tank 15 is connected to the cavity 19.

[0040] An air inlet valve 21 and an air exhaust valve 22 are inserted on the side wall of the telescopic tube 14 , and an air pipe 23 connected to the water tank 15 is fixedly installed on the input end of the exhaust valve 22 .

[0041] By adopting the above technical solution, when the spring 11 stretches and drives the mounting plate 10 to move downward, the telescopic tube 14 inhales air from the outside through the air inlet valve 21. When the mounting plate 10 moves upward and squeezes the telescopic tube 14, the gas in the telescopic tube 14 is squeezed and flows into the water tank 15 through the air pipe 23. At this time, the pressure in the water tank 15 increases, and then under the action of pressure, the aqueous solution in the water tank 15 flows into the cavity 19 through the pressure valve 16 and the water pipe 17, and is evenly sprayed onto the surface of the cutter disc 4 through the water spray hole 20, thereby accelerating the heat dissipation of the surface of the cutter disc 4, thereby effectively preventing the high temperature on the surface of the cutter disc 4 from shortening the service life of the cutter disc 4.

[0042] Specifically, Figure 4 As shown, the inclined surface of the first push block 12 is a smooth mirror surface.

[0043] By adopting the above technical solution, when the second push block 13 drives the first push block 12 to move via the inclined surface of the first push block 12, the second push block 13 will rub against the inclined surface of the first push block 12. By making the inclined surface of the first push block 12 a smooth mirror surface, the friction between the first push block 12 and the second push block 13 can be reduced, thereby ensuring that the second push block 13 drives the first push block 12 to move normally, and reducing the wear between the second push block 13 and the first push block 12, thereby ensuring that the second push block 13 drives the first push block 12 to move normally.

[0044] Specifically, Figure 1 As shown, the armrest 2 is provided with an anti-slip pad 24 .

[0045] By adopting the above technical solution, when the user moves the device through the armrest 2, the friction between the user's hand and the armrest 2 can be increased by arranging the anti-slip pad 24 on the armrest 2. At the same time, when the user holds the anti-slip pad 24, the anti-slip pad 24 is deformed and fits the user's hand, thereby increasing the contact area of ​​the user's hand and improving the comfort of the user.

[0046] Working principle: When in use, the user can start the motor 3 first, and then the user pushes the vehicle body 1 through the armrest 2, and the cutter disc 4 is driven to move during the movement of the vehicle body 1. At the same time, the motor 3 drives the blade 5 to rotate through the cutter disc 4 and perform mowing operations. Since the blade 5 rotates at a high speed, it is easy to cause grass fragments to fly everywhere, and then some of the grass fragments will hit the protective cover 6 and rebound to the surface of the cutter disc 4. At this time, the cutter disc 4 drives the grass fragments to gradually pass through the cleaning hairs 8 during the rotation, and then the grass fragments on the surface of the cutter disc 4 are cleaned under the action of the cleaning hairs 8; during the rotation of the second push block 13, it gradually contacts the inclined surface of the first push block 12 and applies a thrust to the inclined surface of the first push block 12, and then under the action of the thrust, the first push block 12 drives the brush plate 7 and the mounting plate 10 to move upward and squeeze the spring 11. When the second push block 13 and the first push block 12 After the contact is broken, the spring 11 stretches and drives the brush plate 7 to reset through the mounting plate 10, that is, during the operation of the cutter disc 4, the brush plate 7 can be driven to shake through the second push block 13, and then the bristles can be driven to shake during the shaking of the brush plate 7, and the grass clippings adhering to the bristles gradually break contact with the bristles during the shaking of the bristles; by providing the telescopic tube 14, the spring 11 can be isolated from the outside world, thereby effectively preventing the grass clippings from adhering to the surface of the spring 11 and affecting the normal expansion and contraction of the spring 11; when the mounting plate 10 moves upward and squeezes the telescopic tube 14, the gas in the telescopic tube 14 is squeezed and flows into the water tank 15 through the air pipe 23. At this time, the pressure in the water tank 15 increases, and then under the action of the pressure, the aqueous solution in the water tank 15 flows into the cavity 19 through the pressure valve 16 and the water pipe 17, and is evenly sprayed onto the surface of the cutter disc 4 through the water spray hole 20.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
