Description

Technical Field

[0001] This utility model relates to the field of sanitation sweeper technology, specifically a sanitation sweeper that facilitates brush replacement. Background Technology

[0002] Sanitation sweepers are mainly used for road sweeping, garbage collection, and sewage treatment. Of course, their primary function is the cleaning and maintenance of urban roads. Sanitation sweepers can help urban sanitation teams quickly and efficiently remove garbage, leaves, mud, and other debris from roads, ensuring that urban roads remain clean and tidy.

[0003] One of the most important pieces of equipment on a sanitation sweeper is the brush disc, which has brushes at the bottom. Rotating the brush disc causes the brushes to turn, thus achieving the function of sweeping the road. However, with increased use, prolonged friction with the ground will cause the brushes to wear down, reducing the sweeping effect. Therefore, the brush disc needs to be replaced regularly. Currently, most sanitation sweeper brush discs are fixed to the vehicle body / turntable with bolts, making installation and disassembly cumbersome, time-consuming, and labor-intensive, which is not conducive to sanitation work.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Figures 1-5 The diagram shown is a complete structural schematic of a sanitation sweeper vehicle with an easily replaceable brush disc according to this utility model. Please refer to [link / reference]. Figures 1-5This embodiment of a sanitation sweeper with easily replaceable brush discs includes a brush disc base 100. The brush disc base 100 has right-angled triangular hooks 110 on both sides of its top. A turntable 200, horizontally rotatable and mounted on the bottom of the frame, is positioned directly above the brush disc base 100. Card holders 300 are fixed to both sides of the turntable 200. A slot 301 is provided on one side of the inside of each card holder 300. The lower part of the slot 301 extends through the bottom of the card holder 300, and the through opening is a connector 311. This connector 311 connects with… The right triangle hook 110 is vertically aligned, and the slot 301 has a limiting groove 302 on one side. The limiting groove 302 is slidably matched with a locking pin 310. The inner end of the limiting groove 302 is provided with a spring 320 that abuts against the locking pin 310. The locking pin 310 is also fixed with a lever 330 that passes through the outer side of the card holder 300. When the brush base 100 and the turntable 200 are not installed, the outer end of the locking pin 310 abuts against the inner side of the slot 301 under the action of the spring 320.

[0025] The brush base 100 also has brush whiskers 120 at its bottom, with the whiskers 120 spreading downwards. A connecting rod 111 fixed to the top of the brush base 100 is also present on one side of the right-angle hook 110. The overall height of the connecting rod 111 and the right-angle hook 110 is greater than the depth of the slot 301. The locking pin 310 has a slope at the lower end of one end of the slot 301 that matches the slope of the right-angle hook 110. With the cooperation of the slope, when the right-angle hook 110 presses against the locking pin 310, it can laterally slide the locking pin 310 into the limiting groove 302. The card holder 300 is also provided with a limiting pull groove 303 connected to the limiting slide groove 302 on the outer side, and the lever 330 is located inside the limiting pull groove 303. At the same time, the outer end of the lever 330 extends to the outer edge of the limiting pull groove 303. This allows the operator's fingers to directly contact the lever 330 and move the lever 330 and the locking pin 310 when replacing it, which is simple and convenient. Specifically, during installation, the upper end of the brush base plate 100 can be directly placed against the bottom of the turntable 200, so that the right triangular hook 110 is aligned with the insertion port 3011 and inserted into the slot 301. During this process, the locking pin 310 will slide into the inner side of the limiting groove 302 under the oblique push of the hook. When the right triangular hook 110 is fully inserted into the inner end of the slot 301, the locking pin 310 will quickly return to its original position under the action of the spring 302, and form a locking and locking action on the right triangular hook 110 in the slot 301. During disassembly, simply use both hands to push the two side blocks 330 along with the locking pin 310 into the limiting groove 302. After the right triangular hook 110 and the brush base plate 100 are freed from restraint and under the action of gravity, they will directly fall off into the card seat 300, thus completing the disassembly operation. In summary, this easy-to-replace brush plate can achieve quick installation and disassembly with the sweeper, and has the characteristics of stable structure, time-saving and labor-saving, which is conducive to the efficient development of sanitation work.

[0026] Based on the above embodiments, in order to further improve the strength and stability of the brush plate structure after installation, multiple positioning cylinders 130 are fixed around the top of the brush plate base 100, and positioning holes 201 that fit and match the positioning cylinders 130 are around the bottom of the turntable 200. The positioning cylinders 130 also have elastic pads 131 at their tops. After the brush plate base 100 and the turntable 200 are engaged, the positioning cylinders 130 are inserted into the positioning holes 201. Thus, when the turntable 200 drives the brush plate base 100 to rotate rapidly, the insertion and engagement of the positioning cylinders 130 and positioning holes 201 effectively enhances the connection strength between the two plates, preventing deformation or even breakage of the engagement structure. Furthermore, the elastic pads 131 ensure that the positioning cylinders 130 are firmly and vertically pressed against the positioning holes 201, making the brush plate base 100 more stable and preventing shaking during use.

[0027] Furthermore, a rotating shaft 400 coaxially attached to the top of the turntable 200 is fixed thereon. The rotating shaft 400 is rotatably mounted on the bottom of the frame and driven to rotate by the drive device. It can be understood that the rotating shaft 400 can hoist and stabilize the turntable 200. At the same time, the upper end of the rotating shaft 400 is also connected to the drive device. In use, the drive device drives the rotating shaft 400, the turntable 200 and the brush plate to rotate rapidly, thereby achieving the purpose of cleaning the ground.

[0028] In summary, this embodiment of a sanitation sweeper with an easy-to-replace brush disc allows for easy installation. During installation, the upper end of the brush disc base 100 is directly placed against the bottom of the turntable 200, aligning the right-angle hook 110 with the insertion port 3011 and inserting it into the slot 301. During this process, the locking pin 310 slides into the inner side of the limiting groove 302 under the oblique push of the hook. When the right-angle hook 110 is fully inserted into the inner end of the slot 301, the locking pin 310 quickly resets under the action of the spring 302, locking the right-angle hook 110 in the slot 301. During disassembly, simply use both hands to push the two side levers 330 along with the locking pin 310 into the limiting groove 302. After the right-angle hook 110 and the brush disc base 100 are released from their restraints and under the action of gravity, they will directly fall off into the mounting base 300, thus completing the disassembly operation. In summary, this easy-to-replace brush disc enables quick installation and disassembly of the sweeper.
