[0003] According to the disclosed wheelbarrow outer tire that is not easy to deform (publication number: CN218876773U), the above application has comprehensive properties such as high temperature resistance, chemical corrosion resistance, high strength, and wear resistance by providing hydrogenated nitrile rubber and steel wire layers. It can effectively solve the problem of tire deformation caused by excessive temperature due to long-term friction between the tire and the ground. At the same time, it can increase the wear resistance of the tire and reduce the wear caused by friction between the tire and the ground, effectively increasing the service life of the tire and reducing the economic expenditure of consumers.

[0004] Grooves are usually provided on the surface of tires to reduce or prevent hydroplaning and improve the grip of the tires with the ground. The outer tire of the device is also provided with grooves. However, in actual use, although the grooves can make the tire move more stably, it is also very easy for small stones to get stuck inside the grooves. If not handled in time, after the tire has rolled for a long time, the mutual compression between the stones and the tire may cause the tread pattern on the tire surface to deform or even rupture, which will cause damage to the tire and seriously affect the service life of the tire.

The transverse groove 3 can prevent the tire 2 from hydroplaning and improve the grip of the tire 2 with the ground. A bearing 4 is fixedly installed on the inner wall of the wheel hub 1. When the shaft 5 is installed on the wheelbarrow through a flange 6, the wheel hub 1 can be rotated by setting the bearing 4. The inner wall of the bearing 4 is fixedly installed with the shaft 5, and the outer wall of the shaft 5 is fixedly installed with a flange 6. Before use, a shovel plate 7 needs to be fixedly installed. 5 and the brush 82 are kept facing upward, and the flange 6 is installed on the trolley by bolts, so that the wheel hub 1 and the trolley can be installed. After the installation is completed, the shovel plate 75 and the brush 82 are still kept facing upward. The rotating shaft 5 is provided with a cleaning mechanism 7 for cleaning gravel. By setting the cleaning mechanism 7, the stones stuck in the transverse groove 3 can be cleaned in time to prevent the stones from pressing the tire 2 when the tire 2 is rolling. The rotating shaft 5 is provided with an auxiliary mechanism 8. By setting the auxiliary mechanism 8, the fine stones attached to the surface of the tire 2 can be brushed off to prevent the fine stones from squeezing the tire 2.

[0025] The cleaning mechanism 7 comprises a push rod 71, a connecting rod 72, a spring 73, an arc plate 74 and a shovel plate 75; the push rod 71 is slidably connected to the inner wall of the rotating shaft 5, and the push rod 71 passes through the rotating shaft 5, one end of the connecting rod 72 is fixedly mounted on the outer wall of the push rod 71, and the other end of the connecting rod 72 is fixedly mounted with an arc plate 74, and the connecting rod 72 is driven by the push rod 71 to move toward the end close to the wheel hub 1, and at the same time, the arc plate 74 can drive the shovel plate 75 to enter the interior of the transverse groove 3, and the side wall of the arc plate 74 is fixedly mounted with a shovel plate 75. Before use, the shovel plate 75 needs to be aligned with the The brush 82 is kept facing upward, and the flange 6 is installed on the trolley by bolts. The shovel plate 75 can be used to shovel out the stones stuck in the transverse groove 3, so that the stuck stones can be cleaned in time to prevent the stones from pressing the tire 2 and causing the surface of the tire 2 to deform. One end of the spring 73 is fixedly installed on the inner wall of the rotating shaft 5, and the other end of the spring 73 is fixedly installed on the side wall of the push rod 71. The push rod 71 is pushed to move the push rod 71 toward the inside of the rotating shaft 5 and compress the spring 73. The push rod 71 is released, and the push rod 71 can be pushed outward and reset by the elasticity of the spring 73.

[0026] The auxiliary mechanism 8 includes a slide bar 81, a brush 82, a cam groove 83, and an L-bar 84; the slide bar 81 is slidably connected to the inner wall of the rotating shaft 5, and a brush 82 is fixedly installed on the top of the slide bar 81. The slide bar 81 drives the brush 82 to move back and forth, and the reciprocating movement of the brush 82 can brush off the fine stones attached to the surface of the tire 2, further improving the cleaning effect of the tire 2. The brush 82 is attached to the outer wall of the tire 2. When the wheel hub 1 drives the tire 2 to roll on the ground, the brush 82 is attached to the outer wall of the tire 2. The brush 82 can be used to clean the small stones attached to the surface of the tire 2 to prevent the small stones from squeezing the tire 2. A cam groove 83 is provided on the wheel hub 1, and an L rod 84 is fixedly installed on the side wall of the slide bar 81. The end of the L rod 84 away from the slide bar 81 is attached to the inner wall of the cam groove 83. When the wheel hub 1 rotates, the cam groove 83 will be driven to rotate synchronously. The rotation of the cam groove 83 can reciprocately squeeze the L rod 84, so that the L rod 84 drives the slide bar 81 to slide reciprocally on the inner wall of the rotating shaft 5.

[0027] Working principle: Before use, the shovel plate 75 and the brush 82 need to be kept facing upward, and then the flange 6 is installed on the trolley with bolts, so that the wheel hub 1 and the trolley can be installed. At this time, the trolley can be moved by the wheel hub 1 and the tire 2. When the trolley moves through the wheel hub 1 and the tire 2, when a stone is stuck inside the transverse groove 3, the wheel hub 1 is first rotated to make the wheel hub 1 drive the tire 2 to rotate, and the tire 2 rotates the transverse groove 3 where the stone is stuck to the shovel plate 75 to keep it in a coincidence state, and then the trolley is pushed. The push rod 71 is moved to move toward the inside of the rotating shaft 5 and compress the spring 73. At the same time, the push rod 71 drives the connecting rod 72 to move toward the end close to the wheel hub 1. At the same time, the arc plate 74 can drive the shovel plate 75 to enter the inside of the transverse groove 3. The shovel plate 75 can be used to shovel out the stones stuck in the transverse groove 3, so that the stuck stones can be cleaned in time to avoid the stones pressing on the tire 2 and causing deformation of the tire 2 surface. At the same time, it can also prevent the stones from squeezing the tire 2, thereby increasing the service life of the tire 2.

[0028] When the rotating shaft 5 is fixed to the trolley through the flange 6, the trolley can be moved by pushing the trolley so that the wheel hub 1 drives the tire 2 to roll on the ground. At the same time, the brush 82 can be used to clean the small stones attached to the surface of the tire 2 to prevent the small stones from squeezing the tire 2. The rotation of the wheel hub 1 will drive the cam groove 83 to rotate synchronously. The rotation of the cam groove 83 can reciprocate and squeeze the L rod 84, so that the L rod 84 drives the slide bar 81 to slide reciprocally on the inner wall of the rotating shaft 5. At this time, the slide bar 81 will drive the brush 82 to move reciprocally synchronously. The reciprocating movement of the brush 82 can brush off the small stones attached to the surface of the tire 2 to prevent the small stones from squeezing the tire 2, thereby further improving the cleaning effect of the tire 2.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
