A type of urban road sweeper

Abstract

This utility model discloses an urban road sweeper, relating to the technical field of urban road sweeper technology. It aims to solve the technical problem that existing urban road sweeper high-efficiency suction devices easily become tangled and clog the suction port when sucking up excessive amounts of fibrous and hair-like waste. The sweeper includes a lifting frame and a gathering component disposed on the outer wall of the lifting frame. During the vehicle's movement, the high-efficiency suction device of this utility model uses two soft shovels, A and B, arranged in a figure-eight shape, to gather most of the waste in the central gap, facilitating pre-sucking of the waste before the disc brush. During suction, the shredder rotates at high speed, first crushing the sucked-in waste, pre-breaking fibers, hair, or large, easily breakable waste to reduce clogging. Simultaneously, the scraper swings back and forth synchronously, continuously scraping the surface of the filter screen to further prevent clogging, resulting in excellent anti-clogging performance.

Description

Technical Field

[0001] This utility model relates to the field of urban road sweeper technology, and more specifically, to an urban road sweeper. Background Technology

[0002] Urban road sweepers primarily clean roads using a retractable and rotatable disc brush under the vehicle, supplemented by water spray nozzles. They are generally equipped with an auxiliary dust suction device, which helps to suck up light dust, debris, and other pollutants while the disc brush is rotating and sweeping, thus reducing dust pollution and improving sweeping efficiency to a certain extent.

[0003] The high-efficiency dust collection device of urban road sweepers is usually arranged in front of the disc brush. It first absorbs such easily tangled materials before the disc brush comes into contact with the garbage, thereby reducing the entanglement of fibers and hair on the disc brush, reducing the risk of the disc brush getting stuck and extending its service life. However, in actual use, when sucking up too much fiber and hair garbage, they are easy to get tangled together and easily block the dust collection port. In view of this, we propose an urban road sweeper. Utility Model Content

[0004] The purpose of this invention is to provide an urban road sweeper to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sweeper includes a lifting frame; An aggregating assembly, disposed on the outer wall of the lifting frame, includes a flexible shovel A and a flexible shovel B, which are arranged in a figure-eight shape. A vacuuming assembly is disposed between soft shovel A and soft shovel B, including a vacuum nozzle, which is a capsule-shaped shell, with a vacuum port at the top and a filter screen installed at the inlet of the vacuum port; The anti-clogging component includes two sets of shredders distributed at both ends below the suction port, and both sets of shredders can be driven by an electric motor. The scraper, with one end connected to the inner wall of the suction nozzle via a rotating rod, can be driven by an electric motor to swing back and forth along the rotating rod, thus scraping the surface of the filter screen.

[0006] As a further description of the above technical solution: the sweeper also includes a vehicle body, and several sets of lifting frames are installed at the bottom of the vehicle body and disc brushes are installed through the lifting frames.

[0007] As a further description of the above technical solution: both the flexible shovel A and the flexible shovel B are equipped with brackets on their tops, and both the flexible shovel A and the flexible shovel B are mounted on the outer wall of the lifting frame through the brackets.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a sweeper 1 includes a lifting frame 102; In another embodiment of the present invention, preferably, the sweeper 1 further includes a vehicle body 101, and a plurality of lifting frames 102 are installed at the bottom of the vehicle body 101 and a disc brush 103 is installed through the lifting frames 102. Each lifting frame 102 is rotatably mounted with a disc brush 103 at its end. The disc brush 103 can be driven by an existing external electric motor to rotate for road sweeping.

[0017] The gathering component 2 is located on the outer wall of the lifting frame 102 and includes a soft shovel A201 and a soft shovel B202. The soft shovel A201 and the soft shovel B202 are arranged in a figure-eight shape. The garbage scattered in the area swept by the soft shovel A201 and the soft shovel B202 can be gathered towards the edge or the middle area. The garbage gathered in the middle area is convenient to be vacuumed and treated by the vacuuming component 3. In another embodiment of this utility model, both the top of the flexible shovel A201 and the flexible shovel B202 are equipped with brackets 203, and both the flexible shovel A201 and the flexible shovel B202 are installed on the outer wall of the lifting frame 102 through the brackets 203, which facilitates installation.

[0018] The vacuuming assembly 3 is located between the soft shovel A201 and the soft shovel B202 and is installed by an existing external bracket. It includes a vacuum nozzle 302, which is a capsule-shaped shell. The top of the vacuum nozzle 302 has a vacuum port 303 and a filter screen 304 is installed at the inlet of the vacuum port 303. The filter screen 304 is used to intercept larger debris and prevent air from being sucked into the pipe and clogging the pipe. In another embodiment of the present invention, a suction pipe 301 is installed at the suction port 303 at the top of the suction nozzle 302, and a vehicle vacuum cleaner is installed at the end of the suction pipe 301.

[0019] The anti-clogging component 4 includes two sets of crushing blades 401 distributed at both ends below the suction port 303. Both sets of crushing blades 401 can be driven by the motor 404. When sucking in light waste, the light waste can be pre-crushed to reduce the risk of large-volume waste being sucked into the suction pipe 301 and clogging the suction pipe 301. The scraper 409 is rotatably connected to the inner wall of the suction nozzle 302 via a rotating rod. It can be driven by the motor 404 and swings back and forth along the rotating rod to scrape the surface of the filter screen 304 and further prevent clogging.

[0020] In another embodiment of the present invention, a gear A402 is connected to the shaft of the crusher 401 via a rotating rod, a motor 404 is connected to the power input end of the gear A402, and a gear B403 is meshed with the outer wall of the gear A402.

[0021] In another embodiment of this utility model, an active disk 405 is coaxially mounted on the outer wall of gear B403. The active disk 405 includes a disk body and a pin, and a sliding frame 406 is slidably connected to it through the pin. A sector gear 407 is fixed at the other end of the sliding frame 406. The axis of the sector gear 407 is rotatably connected to the outer wall of the suction nozzle 302 through a rotating rod. A gear C408 is meshed with the outer wall of the sector gear 407. The gear C408 is located at the top of the rotating rod at the axis of the scraper 409.

[0022] Working principle: This embodiment provides a city road sweeper. When in use, first adjust the existing product lifting frame 102 at the bottom of the vehicle body 101. The vehicle body 101, lifting frame 102 and disc brush 103 are all existing products. The lifting frame 102 can be driven by the existing product hydraulic rod, so that the disc brush 103, soft shovel A201, soft shovel B202 and suction nozzle 302 are all lowered to the target position. During the movement of the vehicle body 101, the soft shovel A201 and soft shovel B202, which are arranged in a figure-eight shape, can collect the garbage scattered in the swept area to the edge or middle area. The garbage collected in the middle area is convenient to be vacuumed by the suction component 3. Powered by an external power source, the motor 404 and the car vacuum cleaner are turned on via an external switch. The motor 404 drives the shredder 401 to rotate at high speed. When the car vacuum cleaner sucks in floating debris through the suction pipe 301 and the suction nozzle 302, the shredder 401 first shreds the sucked-in debris, pre-crushing fibers, hair, or large, easily breakable debris to reduce clogging. The shredded debris is then sucked into the suction port 303. Smaller debris that can pass through the filter screen 304 is sucked into the suction pipe 301 and discharged to the outlet of the suction pipe 301, while larger debris is intercepted by the filter screen 304. While the shredder 401 is shredding, the motor 404 is driven by the transmission assembly. The active disc 405 rotates synchronously. The active disc 405 includes a disc body and a pin, and a sliding frame 406 is slidably connected to it through the pin. A sector gear 407 is fixed to the other end of the sliding frame 406. The axis of the sector gear 407 is rotatably connected to the outer wall of the suction nozzle 302 through a rotating rod. This can drive the sector gear 407 to rotate back and forth alternately within a certain angle range. A gear C408 is meshed with the outer wall of the sector gear 407, which drives the gear C408 to rotate back and forth alternately within a certain angle range. This drives the scraper 409 to swing back and forth along the rotating rod at the axis, continuously scraping the surface of the filter screen 304 to remove debris, further preventing clogging. The clogging prevention effect is excellent. In actual use, the size of the transmission components needs to be customized according to the internal space of the vacuum nozzle 302 and the size of the filter screen 304, so that when the scraper 409 swings back and forth, it can continuously scrape the surface of the filter screen 304 without colliding with the inner wall of the vacuum nozzle 302 (the vehicle body 101, lifting frame 102, disc brush 103, motor 404 and vehicle vacuum cleaner are all existing products, and the lifting frame 102, motor 404 and vehicle vacuum cleaner are all connected to the external power supply and external switch).

[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
