Description

Technical Field

[0001] The utility model relates to the field of sanitation vehicle accessories, in particular to a sanitation cleaning floor brush. Background Art

[0002] The cleaning and treatment of urban garbage has become an indispensable part of urban maintenance. Sanitation vehicles play an important role in urban maintenance. They are special vehicles used for urban appearance tidying and cleaning, and perform road sweeping and road maintenance work.

[0003] Sanitation vehicles mainly rely on floor brushes for cleaning. In actual use, due to the undulations of the ground, the rapidly rotating floor brush will produce eccentric wear after contacting the raised parts of the road surface, which will increase the wear of the bristles in contact with the raised parts of the road surface. The purpose of the utility model is to propose a new floor brush structure to solve the problem of increased wear of the floor brush after contacting the raised road surface. Utility Model Content

[0004] The utility model aims to provide a sanitation cleaning brush to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a connecting rod, a brush disc, a limiting ring and an elastic supporting sheet, the bottom end of the connecting rod is provided with a limiting block, the limiting blocks are arranged at equal intervals and are radially distributed, the bottom surface of the brush disc is provided with bristles, the top surface of the brush disc is concave to form a limiting groove for accommodating the limiting block, the depth of the limiting groove is greater than the thickness of the limiting block, the limiting ring is detachably arranged on the top surface of the brush disc, and an opening for the connecting rod to pass through is formed in the center of the limiting ring, and the elastic supporting sheets are respectively arranged on the upper and lower sides of the limiting block, respectively resisting the limiting ring and the limiting groove.

[0006] To optimize the above technical solution, further measures are taken: the length of the limit block is smaller than the length of the limit slot, so that the limit block has a certain mobility in the front and rear length direction of the limit slot.

[0007] As a further limitation of the above technical solution: the width of the limit block is smaller than the width of the limit slot, so that the limit block and the limit slot have a certain degree of mobility in the left and right width directions.

[0008] As a further improvement of the utility model: the end of the limit block is concave to form a slide groove, a ball seat is arranged in the slide groove to form a moving pair with the slide groove, a rolling ball is embedded and installed on the ball seat to form a spherical pair with the ball seat, a spring is arranged in the slide groove and the two ends of the spring respectively press against the ball seat and the slide groove, and the spring is expanded to make the rolling ball press against the limit groove so that the limit block can be close to the limit groove.

[0009] Furthermore: the length direction of the slide groove is parallel to the length direction of the limit block.

[0010] Furthermore: the bolts are distributed along the circumference of the limit ring, and the bolts penetrate the limit ring and are threadedly connected to the brush disc to achieve a detachable connection between the limit ring and the brush disc. When the bristles on the brush disc are worn or damaged, the detachable limit ring helps the operator to replace the brush disc.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0012] The utility model provides a sanitation cleaning floor brush, which cooperates with a limiting block and a limiting groove. When the floor brush contacts an uneven surface, the relative positions of the limiting block and the limiting groove change, so that the brush plate is tilted to adapt to the undulations of the ground, thereby reducing the wear of the bristles and helping to increase the service life of the floor brush.

[0020] Example

[0021] See also Figure 1-4The utility model provides a sanitation cleaning floor brush, including a connecting rod 1, a brush disc 2, a limiting ring 3 and an elastic supporting sheet 4. The bottom end of the connecting rod 1 is provided with a limiting block 101, and the limiting blocks 101 are arranged at equal intervals and are radially distributed. The bottom surface of the brush disc 2 is provided with bristles 201, and the top surface of the brush disc 2 is concave to form a limiting groove 202 for accommodating the limiting block 101. The depth of the limiting groove 202 is greater than the thickness of the limiting block 101, and the width of the limiting block 101 is less than the limiting groove. 202, the length of the limit block 101 is less than the length of the limit groove 202, the limit ring 3 is detachably arranged on the top surface of the brush disc 2, the bolts are distributed circumferentially along the limit ring 3, the bolts penetrate the limit ring 3 and are threadedly connected with the brush disc 2 to realize the detachable connection between the limit ring 3 and the brush disc 2, and an opening 301 is formed in the center of the limit ring 3 for the connecting rod 1 to pass through, and the elastic support sheet 4 is respectively arranged on the upper and lower sides of the limit block 101, respectively against the limit ring 3 and the limit groove 202.

[0022] A slide groove 102 is formed at the end of the limit block 101, and a ball seat 103 is arranged in the slide groove 102 to form a moving pair with the slide groove 102. A rolling ball 104 is embedded and installed on the ball seat 103 to form a spherical pair with the ball seat 103. A spring 105 is arranged in the slide groove 102, and the two ends of the spring 105 respectively press against the ball seat 103 and the slide groove 102, and the length direction of the slide groove 102 is parallel to the length direction of the limit block 101.

[0023] The connecting rod 1 refers to a rod-shaped component that plays a connecting role, which is used to connect to the sweeping structure on the sanitation vehicle. The specific structure to be used for the connection and how to connect are known to those skilled in the art, so the specific structure of the connecting rod 1 will not be further explained.

[0024] The elastic support sheet 4 refers to a sheet-like component made of elastic material that plays a supporting role. The specific elastic material used is not a comparative technical feature nor a technical content that the applicant wants to protect. During implementation, technicians can choose different elastic materials according to actual needs, and it will not have a substantial impact on the technical effect.

[0025] Working principle: The floor brush is installed on the sanitation vehicle through the connecting rod 1. The sanitation vehicle drives the floor brush to rotate to perform the cleaning operation on the road surface. During the process, the upper and lower surfaces of the limit block 101 are clamped by the elastic support sheet 4 and the left and right sides of the limit block 101 are limited by the limit groove 202. The limit block 101 will not detach from the limit groove 202 to affect the rotation of the brush plate 2.

[0026] When the local brush contacts the inclined or uneven road surface, the raised road surface presses against the bottom of the bristles 201. At this time, the force can be transmitted to the limit block 101, so that the limit block 101 squeezes the elastic support sheet 4. After being squeezed, the elastic support sheet 4 generates elastic compression, which helps the brush disc 2 to move up and adapt to the uneven road surface, and reduces the wear of the bristles 201. After the local brush leaves the uneven road surface, the elastic support sheet 4 is reset. At this time, the elastic support sheet 4 restores and drives the limit block 101 to reset. During the process, the rolling ball 104 set at the end of the limit block 101 presses against the limit groove 202, which can improve the smoothness of the movement of the limit block 101 in the limit groove 202.

[0027] When the bristle layer 201 is worn, the operator can remove the limiting ring 202 and replace the new brush disc 2 without scrapping the entire floor brush, which helps to improve resource utilization efficiency and reduce waste.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
