[0002] At present, handcarts are mainly used to carry light-weight and easy-to-load items, especially in places with poor environments and difficult for vehicles to enter, such as the transportation of crops such as soybeans and corn.

[0003] Most of the existing wheelbarrow wheel spokes are composed of a solid wheel hub and a spoke rod.

[0004] When a wheelbarrow is traveling on a muddy ground, due to the presence of a large amount of weeds in the soil and its high viscosity, the clay on the ground will splash and adhere to the wheel hub, thereby increasing the burden on the wheelbarrow and failing to ensure the stability of the wheelbarrow during driving.

[0005] Traditionally, circular holes are opened on the wheel hub to facilitate the clay to fly out of the holes. However, if the circular holes are too large, the spokes will not be able to withstand the heavy load, resulting in the wheel being unable to maintain stability when driving on different surfaces.

[0006] In view of this, how to solve the defects existing in the above technical solutions has become one of the problems to be solved urgently in the field of wheelbarrow wheel spoke technology. Utility Model Content

[0046] The wheel provided in the present application is mainly used for wheelbarrows. Of course, the spokes provided in the present application can also be used for bicycles or agricultural vehicles.

[0047] like Figures 1 to 3 As shown, this embodiment provides a wheelbarrow wheel spoke that can prevent mud from adhering, including a spoke body 100, a hub 20 is arranged at the center of the spoke body 100, and a rim 10 is arranged at a position away from the hub 20, and the rim 10 and the hub 20 are connected by a reinforcing rib 40.

[0048] Most of the existing wheelbarrow spokes are composed of a solid wheel hub and spoke rods. When the wheelbarrow is traveling on a muddy ground, due to the presence of a large number of weeds and high viscosity in the soil, the clay on the ground will splash and adhere to the wheel hub, thereby increasing the burden on the wheelbarrow and failing to ensure the stability of the wheelbarrow during driving. Traditionally, a round hole is opened on the wheel hub to facilitate the clay to fly out of the hole, but if the round hole is too large, the wheel spoke will not be able to bear a large load, resulting in the wheel being unable to maintain stability when traveling on different ground surfaces. In order to solve the above technical problems, please refer to Figures 1 to 3 As shown, a plurality of grooves 101 are provided in the rim 10 , and the grooves 101 are evenly distributed along the circumference of the rim 10 , and at least one group of steel balls 102 is disposed in the grooves 101 .

[0049] Furthermore, the cross section of the groove body 101 is arranged in an arc shape, and the depth of the groove body 101 is 1.5-4.5 mm, and the inclination angle α of the groove body 101 is 18°-36.5°. When the inclination angle α is 33.5°, the steel ball rolls more smoothly.

[0050] Furthermore, a through hole 103 penetrating the inner cavity of the reinforcing rib 40 is opened on the outer wall of the rim 10 near the groove body 101 , so as to facilitate the steel ball 102 to flow from the rim 10 into the inner cavity of the reinforcing rib 40 .

[0051] Furthermore, a movable plate 105 is slidably installed in the inner cavity of the reinforcing rib 40 , and the inner cavity of the reinforcing rib 40 is divided into a first cavity 104 and a second cavity 108 by the movable plate 105 .

[0052] Furthermore, the movable plate 105 is made of elastic material so as to have a certain elastic margin, thereby facilitating the movable plate 105 to be pushed into the second cavity 108 under the action of thrust.

[0053] Furthermore, an elastic component 106 is fixedly mounted on the movable plate 105 facing the second cavity 108 by means of a fixing connection such as a fastening screw, and the other end of the elastic component 106 is fixedly mounted on the inner wall of the reinforcing rib, and the elastic component 106 preferably compresses a telescopic spring.

[0054] In this embodiment, the structure is simple and can minimize the probability of clay adhering to the wheel spokes. When the wheel is in use, it will generate a certain vibration when it is running, especially when it is running in a clay field with potholes, it will generate a greater vibration force. The steel balls in the groove body 101 pass through the through hole 103 under the action of the vibration force, and multiple groups of steel balls flow downward into the first cavity 104 and generate a certain impact force. Under the action of the impact force, the moving plate 105 is pushed to move toward the second cavity 108, thereby pressing the elastic component 106;

[0055] When the impact force disappears, the elastic potential energy of the elastic component 106 is used to rebound, thereby pushing the steel balls behind the moving plate to continuously impact the ribs 107 of the reinforcing ribs 40 to generate greater vibrations, thereby removing the mud on the spokes and preventing the mud from adhering to the spokes.

[0056] Furthermore, a reinforcing plate 30 is fixedly mounted on the wheel hub 20 by means of a fixing connection such as a fastening screw, and at least one group of protrusions is arranged on the reinforcing plate 30 along the circumferential direction, so that the reinforcing plate 30 is arranged in a fan shape as a whole.

[0057] Furthermore, at least one group of first grooves 50 are formed on the inner circle of the reinforcing plate 30, and the first grooves 50 are evenly distributed along the circumferential direction. At least one group of second grooves 501 are formed on the outer circle of the reinforcing plate 30, and the second grooves 501 are arranged in an arc shape.

[0058] In this embodiment, when the cart is moving, the rotation of the wheel drives the reinforcing plate 30 arranged in a fan shape to rotate. At this time, the protrusion of the reinforcing plate will throw the clay off, and at the same time, the first cavity 104 and the second cavity 108 on the reinforcing plate 30 produce a weak "drainage effect" similar to the rotation of a fan through the rotation of the wheel, which facilitates the air to pass through the groove body, accelerates the drying speed of the clay on the spokes, and then facilitates the dried clay to fall from the spokes.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not restrictive. Although the utility model is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
