Description

Technical Field

[0001] The utility model relates to the technical field of sanitation brushes, and particularly relates to a sanitation brush which is convenient to replace. Background Art

[0002] In the field of sanitation operations, as a core cleaning component, sanitation brushes are widely used in equipment such as road sweepers, snow sweepers, and wall cleaning machines. There are significant defects in the structural design of traditional sanitation brushes. The bristles and the turntable are mostly fixedly connected rather than separately connected. This design results in a replacement time of usually more than 30 minutes each time and requires the cooperation of special tools.

[0003] Therefore, it is urgent to innovate the design of the brush and the turntable assembly in the sanitation brush to solve the above problems. Content of the Utility Model

[0004] In order to make up for the deficiencies in the prior art and achieve the above functions, the utility model provides a sanitation brush which is convenient to replace.

[0005] The utility model is realized by the following technical solutions: A sanitation brush which is convenient to replace, comprising a rotating body with a center and a connecting body fixed by bolts. The rotating body is disc-shaped and a plurality of brush grooves are arranged on the circular ring edge thereof. A brush assembly is clamped in each brush groove, and the brush at the bottom of the brush assembly extends out from the bottom square hole of the brush groove; The edge and the bottom of the edge of the rotating body are inclined. A cover plate is arranged on the outer layer of the rotating body and abuts against it. The cover plate is a fan-shaped arc and three of them are in a group to surround the outer layer of the whole rotating body; The brush assembly includes a clamping block located in the brush groove. A pair of magnetic blocks a are embedded in the inner wall of the clamping block, and two magnetic blocks b which are attracted to the magnetic blocks a are arranged at the corresponding positions in the brush groove.

[0006] Further, a groove is arranged in the middle of the top of the clamping block and shock-absorbing foam is installed in the groove. The whole clamping block is made of plastic material and is inclined outwards and downwards.

[0007] Further, the brush groove is in an inverted "convex" shape and is in clearance fit with the clamping block.

[0008] Further, the cover plate is in a "factory" - shaped structure, and shock-absorbing cotton is bonded to the inner wall thereof. The shock-absorbing cotton can completely cover the outer end surface of the clamping block.

[0009] Further, a plurality of limit pins and fastening bolt holes are arranged on the top of the rotating body, and limit card slots and counterbore holes corresponding to the limit pins and the fastening bolt holes are arranged on the cover plate; The limit pins and the fastening bolt holes are both arranged on the rotating body; Each cover plate has at least two limit slots and countersunk holes.

[0010] Furthermore, the connecting body is fixedly connected to the rotating body by a number of positioning bolts on its base.

[0011] The beneficial effects of this utility model are: This invention allows for easy disassembly of the brush assembly simply by removing the bolts on the modified plate and pulling on the brush. Installation is straightforward: simply insert the brush and it will automatically magnetically engage. During rotation, the simultaneous presence of shock-absorbing foam and cotton buffers effectively cushions and dissipates vibrations from the brush's contact with the ground, extending the mechanical components' lifespan.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0015] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0016] As Figures 1 to 6 shown, the present utility model includes a rotating body 1 whose center is fixed to a connecting body 4 by bolts. Of course, a rotating shaft is fixed to the top of the connecting body 4, and the rotating shaft is connected to a sanitation vehicle. The rotating body 1 is disc-shaped, and a plurality of brush grooves 101 are provided at the edge of its ring. A brush assembly 2 is clamped in each brush groove 101. This is the key to cleaning. The brush 204 at the bottom of the brush assembly 2 extends out from the bottom square hole of the brush groove 101. Refer to Figure 3 and Figure 6 ; The edge and the bottom of the edge of the rotating body 1 are inclined to adapt to the inclined brush structure. A cover plate 3 is provided on the outer layer of the rotating body 1 and abuts against it. The cover plate 3 is a fan-shaped arc, and three of them are in a group to surround the outer layer of the entire rotating body 1. Each is convenient for direct disassembly, and it can be removed by directly lifting it up; The brush assembly 2 includes a clamping block 201 located in the brush groove 101. A pair of magnetic blocks a203 are embedded in the inner wall of the clamping block 201. Two magnetic blocks b102 that attract the magnetic blocks a203 are provided at the corresponding positions in the brush groove 101. Refer to Figure 4 Figure 5 , and the two groups of magnetic blocks are used to stabilize the brush assembly 2 and reduce the internal and external vibrations caused by clearance fit.
