Description

Technical Field

[0001] This application relates to the technical field of road cleaning, and in particular to a sanitation equipment for cleaning and maintaining road surfaces. Background Art

[0002] In urban construction and maintenance, the cleaning and maintenance work of road surfaces is an important link in maintaining urban environmental sanitation and ensuring the quality of life of citizens.

[0003] Currently, on the sanitation vehicle for cleaning road surfaces, a rotary brush is used to clean the road surface. The dust and garbage on the road surface are swept by the rotary brush onto the suction pipe and sucked through the suction pipe and concentrated in the dust collection box. However, the rotary brush may be wound around strip-shaped objects during use, such as plastic bags, ropes, fabric fragments, etc., which is likely to reduce the cleaning efficiency of the rotary brush. Since the rotary brush is installed at the bottom of the sanitation vehicle, when the rotary brush gives a winding prompt, the sanitation workers need to get off the vehicle to remove the rotary brush for cleaning or bend down to a low position to clean the rotary brush. The cleaning method is troublesome and the efficiency is low. Summary of the Invention

[0004] In order to improve the convenience of cleaning the rotary brush, this application provides a sanitation equipment for cleaning and maintaining road surfaces.

[0005] This application provides a sanitation equipment for cleaning and maintaining road surfaces, adopting the following technical solutions: A sanitation equipment for cleaning and maintaining road surfaces, comprising: A vehicle body; A rotary brush, including a central roller and bristles; the central roller is rotatably connected to the bottom of the vehicle body, and the bristles are arranged on the central roller and are arranged in multiple rows at intervals along the circumferential direction of the central roller; A suction pipe, arranged at the bottom of the vehicle body, with the inlet facing the rotary brush; A cleaning mechanism, including a base frame, a movable body, a cleaning member and a power assembly; the cleaning members are arranged on the movable body and are arranged at intervals in the width direction of the vehicle body, and the cleaning members have barbs; the movable body moves on the base frame; the base frame is installed on the bottom of the vehicle body and can make the movable body face the rotary brush; the power assembly is installed on the base frame and is used to drive the movable body to move in a direction close to or away from the base frame and perpendicular to the width direction of the vehicle body at the same time, so that when the cleaning members face the rotary brush, the cleaning members can enter the gaps between two adjacent rows of the bristles and reciprocate in directions close to and away from the central roller.

[0006] By adopting the above technical solution, the power component in the cleaning mechanism drives the moving body to move, so that the cleaning part enters the gap between two adjacent rows of bristles and reciprocates in the direction close to and away from the central roller, which can automatically clean the strip-shaped objects wound on the roller brush, avoiding manual dismounting or bending down for cleaning, and improving the cleaning efficiency and convenience.

[0007] Optionally, a plurality of barbs are arranged at intervals along the circumferential direction of the cleaning part.

[0008] By adopting the above technical solution, a plurality of barbs are arranged at intervals along the circumferential direction of the cleaning part, increasing the contact area and grasping ability between the cleaning part and the winding, and being able to clean the winding on the roller brush more effectively, improving the thoroughness of cleaning.

[0009] Optionally, the cleaning part moves on the moving body in the direction close to or away from the base frame, and an elastic member is arranged between the cleaning part and the moving body, and the elastic force of the elastic member gives the cleaning part a tendency to move away from the moving body.

[0010] By adopting the above technical solution, the elastic member can adapt to the error of the flatness of the outer peripheral surface when the cleaning part abuts against the outer peripheral surface of the central roller.

[0011] Optionally, the moving body has a sliding groove for the cleaning part to slide, and the sliding grooves correspond to the cleaning parts one by one; a guiding convex is arranged on the outer wall of the cleaning part, and a guiding groove for the guiding convex to slide is formed on the inner wall of the sliding groove of the moving body, and the guiding groove extends obliquely along the circumferential direction of the sliding groove wall, so that the cleaning part rotates while moving in the direction close to or away from the base frame on the moving body.

[0012] By adopting the above technical solution, the cleaning part rotates while moving in the direction close to or away from the base frame on the moving body, and the barbs can better hook the winding. By rotating, the contact angle and range between the barbs and the winding are increased, further improving the effect of cleaning the winding and making the cleaning more thorough.

[0013] Optionally, the power component can simultaneously drive the moving body and the cleaning part to move along the axial direction parallel to the central roller.

[0014] By adopting the above technical solution, the power component can simultaneously drive the moving body and the cleaning part to move along the axial direction parallel to the central roller, so that the cleaning part can cover a larger range during the cleaning process, clean the winding at different positions of the roller brush, and improve the comprehensiveness and effectiveness of cleaning.

[0015] Optionally, support members are arranged at intervals along the circumferential direction of the central roller, and there is a support member between each adjacent two rows of the bristles. The support member extends along the axial direction of the central roller in parallel, and the end of the bristle away from the central roller protrudes beyond the end of the support member away from the bristle; when the cleaning member extends between adjacent two rows of the bristles, the cleaning member is misaligned with the support member.

[0016] By adopting the above technical solution, the support member can support the winding object close to the central roller and prevent the winding object from adhering to the central roller.

[0017] Optionally, the vehicle body lifts and lowers an installation frame through a telescopic member, and the base frame and the central roller are both installed on the installation frame.

[0018] Optionally, the sanitation equipment further includes a watering member, and the watering member, the dust suction pipe, the rolling brush and the cleaning mechanism are sequentially distributed along the advancing direction of the vehicle body.

[0019] By adopting the above technical solution, when the rolling brush sweeps the road surface, the garbage is swept towards the dust suction pipe, and then the watering member waters the swept road surface to reduce dust.

[0020] Optionally, the base frame is rotatably connected to the vehicle body so that the cleaning member can be arranged downward.

[0021] By adopting the above technical solution, the cleaning member is arranged downward so that the cleaning member can be moved to a position away from the relative position of the rolling brush, reducing the interference between the rolling brush and the cleaning member during operation.

[0022] In summary, the present application includes at least one of the following beneficial effects: 1. The winding object on the rolling brush is cleaned through the movement of the cleaning mechanism, and the contact and grasping ability with the winding object is enhanced through barbs on the cleaning member, so as to improve the cleaning efficiency and convenience; 2. The cleaning member can rotate when moving relative to the moving body, so as to further grasp the winding object, expanding the cleaning range and cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] The following further Figure 1-7 describes the present application in detail with reference to the

[0026] The embodiment of the present application discloses a road surface cleaning, sanitation and cleaning equipment. Referring to Figure 1 and Figure 2 , the road surface cleaning, sanitation and cleaning equipment includes a vehicle body 1, and a cleaning mechanism 4, a rotary brush 2, a dust suction pipe 3 and a watering member 12 which are sequentially distributed along the reverse direction of the vehicle body 1 at the bottom of the vehicle body 1. When the vehicle body 1 moves forward, the rotary brush 2 rotates to sweep the garbage and sundries on the ground towards the dust suction pipe 3, and the dust suction pipe 3 sucks the garbage into the dust collection box of the vehicle body 1. At the same time, the watering member 12 draws water from the water tank of the vehicle body 1 to sprinkle water on the ground to reduce the dust on the swept road surface. When there are sundries wound on the rotary brush 2, the cleaning mechanism 4 is used to clean the winding on the rotary brush 2.

[0027] Among them, the dust suction port of the dust suction pipe 3 extends along the width direction of the vehicle body 1 and faces the rotary brush 2. The watering member 12 includes a plurality of spray heads distributed along the width direction of the vehicle body 1. A telescopic member 10 is installed at the bottom of the vehicle body 1. The telescopic member 10 is an electric telescopic rod arranged vertically, and the telescopic end of the telescopic member 10 is arranged downward. The telescopic end of the telescopic member 10 is fixedly connected with a mounting frame 11. The mounting frame 11 is in the shape of a square box with a plane extending along the horizontal plane. The rotary brush 2 and the cleaning mechanism 4 are both installed on the mounting frame 11.

[0028] Referring to Figure 3 and Figure 4, for the rotary brush 2, the rotary brush 2 includes a central roller 21 and bristles 22. The central roller 21 is in the shape of a round roller and is rotatably connected to the mounting frame 11. The axis of the central roller 21 is parallel to the width direction of the vehicle body 1, and both ends of the central roller 21 away from each other are close to the opposite sides of the vehicle body 1. In order to drive the central roller 21 to rotate, a first motor 13 with an output end coaxially connected to the central roller 21 is installed on the mounting frame 11, and the first motor 13 can rotate forward and backward.

[0029] The bristles 22 are soft. The bristles 22 are installed on the outer periphery of the central roller 21. The bristles 22 are divided into multiple rows on the central roller 21, and each row of bristles 22 is evenly spaced along the circumferential direction of the central roller 21, and each row of bristles 22 is laid along the axial direction of the central roller 21. Therefore, a clearance cavity 14 opposite to the outer periphery of the central roller 21 is formed between adjacent two rows of bristles 22.

[0030] Refer to Figure 2 and Figure 3 , for the cleaning mechanism 4, the cleaning mechanism 4 includes a base frame 41, a movable body 42, a cleaning member 43 and a power assembly 44. The base frame 41 is in the shape of a round roller and is rotatably connected to the mounting frame 11. The axis of the base frame 41 itself coincides with the rotation axis and is parallel to the axis of the central roller 21. At the same time, the axis of the base frame 41 and the axis of the central roller 21 are on the same horizontal plane. In order to drive the base frame 41 to rotate, a second motor 15 with an output end coaxially connected to the base frame 41 is installed on the mounting frame 11, and the second motor 15 can rotate forward and backward.

[0031] Refer to Figure 3 and Figure 5 , the movable body 42 is in the shape of a square strip, and the movable body 42 moves on the base frame 41 through the power assembly 44. Specifically, the extending direction of the length of the movable body 42 is parallel to the axis direction of the base frame 41. The base frame 41 is provided with a movable cavity 16 for the movable body 42 to slide from the outer periphery inward along its own radial direction. The extending length of the movable cavity 16 along the axial direction of the base frame 41 is greater than the extending length of the movable body 42. The power assembly 44 includes a first telescopic power 441 and a second telescopic power 442. The first telescopic power 441 is a multi-stage electric telescopic rod, and the second telescopic power 442 is an electric telescopic rod. A movable seat 17 moves along the axial direction of the base frame 41 on the side of the base frame 41 away from the movable cavity 16. The seat bodies of the first telescopic power 441 are installed on the movable seat 17 and are distributed in two along the axial direction of the base frame 41. The telescopic end of each first telescopic power 441 is connected to the movable body 42, and the telescopic end of the first telescopic power 441 extends and retracts along the radial direction of the base frame 41. The second telescopic power 442 is installed in the base frame 41, and the telescopic end of the second telescopic power 442 is connected to the movable seat 17, and the telescopic end of the second telescopic power 442 extends and retracts along the axial direction of the base frame 41. Thus, the movable body 42 is driven to move along the radial direction of the base frame 41 by the first telescopic power 441, and the movable body 42 is driven to move along the axial direction of the base frame 41 by the second telescopic power 442.

[0032] Reference Figure 5 and Figure 6 ,A cleaning member 43 is installed on the movable body 42, and a plurality of cleaning members 43 are arranged at equal intervals along the length direction of the movable body 42. Specifically, each cleaning member 43 includes a connecting portion 431, an abutting portion 432, and barbs 433. The connecting portion 431 is cylindrical and installed on the mounting body. The abutting portion 432 is frustum-shaped, and the abutting portion 432 is coaxially and fixedly connected to one end of the connecting portion 431, and the outer diameter of the abutting portion 432 gradually decreases in the direction away from the connecting portion 431. The barbs 433 are fixed on the outer circumference of the abutting portion 432, and a plurality of barbs 433 are arranged at equal intervals along the circumferential direction of the abutting portion 432. Each barb 433 is in the shape of a triangular barb extending in the direction close to the connecting portion 431, and the distance from the outer circumference of the barb to the axis of the abutting portion 432 gradually increases in the direction close to the connecting portion 431, and the side of the barb 433 facing the connecting portion 431 is a blade. Among them, the axis of the connecting portion 431 coincides with the extension line of the telescopic end of the first telescopic power 441.

[0033] Reference Figure 6 and Figure 7 ,It should be noted that the connecting portion 431 moves along the telescopic direction of the first telescopic power 441 in the movable body 42. A chute 6 corresponding to the cleaning member 43 one by one for the connecting portion 431 to slide is provided on the movable body 42. An elastic member 5 that applies force to the connecting portion 431 is placed in the chute 6, and the elastic force of the elastic member 5 gives the cleaning member 43 an elastic force to move away from the movable body 42. In this embodiment, the elastic member 5 is a spring. In other embodiments, the elastic member 5 can also be a spring sheet or the like.

[0034] Reference Figure 2 、 Figure 5 and Figure 7 ,The second motor 15 can switch the base frame 41 between the impurity removal position and the deicing position. When the base frame 41 is in the impurity removal position, the cleaning member 43 can clean the roller brush 2. When the base frame 41 is in the deicing position, the cleaning member 43 can strike the icy road surface.

[0035] Specifically, when the base frame 41 is in the impurity removal position, the cleaning member 43 is located on a side of the base frame 41 close to the roller brush 2, and the axis of the connecting portion 431 extends in the horizontal direction. When the cleaning member 43 cleans the roller brush 2, the roller brush 2 is driven by the first motor 13 to step and rotate at a set time interval. When the roller brush 2 stops rotating, the clearance cavity 14 is opposite to the cleaning member 43, and each time the roller brush 2 rotates once at a set step angle, the adjacent clearance cavity 14 is moved to be opposite to the cleaning member 43. During the time when the roller brush 2 stops rotating, the telescopic end of the first telescopic power 441 extends to drive the cleaning piece 43 to enter the yield cavity 14 so that the abutment portion 432 abuts against the outer peripheral wall of the center roller 21. During the process, the cleaning piece 43 will break apart part of the entangled material between adjacent rows of bristles 22; then the telescopic end of the first telescopic power 441 retracts, so that the barb 433 of the cleaning piece 43 hooks the entangled material and pulls it outward, and the blade of the barb 433 contacts the entangled material and can cut the entangled material, while the telescopic end of the second telescopic power 442 reciprocates to expand the cleaning area of ​​the cleaning piece 43.

[0036] When the base frame 41 is in the de-icing position, the cleaning member 43 is located at the bottom side of the base frame 41, and the axis of the connecting portion 431 extends in the vertical direction. At this time, the telescopic end of the first telescopic power 441 is reciprocated and retracted, and the telescopic end of the second telescopic power 442 is reciprocated and reciprocated, so that the cleaning member 43 can knock down the thin ice layer on the road surface to crack the ice layer, so that the crushed ice can be more easily swept up by the subsequent roller brush 2 and sent to the dust suction pipe 3. If the surrounding environment does not meet the conditions for freezing, the water can be sprinkled on the cracked ice layer through the watering member 12, so that the water flow extends into the cracks of the ice layer to accelerate the melting of the ice layer. It should be noted that the speed at which the first telescopic power 441 extends is faster than the speed when the base frame 41 is in the de-icing position, so as to increase the impact force of the cleaning member 43 knocking the ice layer.

[0037] Reference Figure 6 and Figure 7 Furthermore, a guide protrusion 7 is fixed to the outer wall of one end of the connecting portion 431 away from the abutting portion 432, and a guide groove 8 for the guide protrusion 7 to slide is provided on the inner wall of the slide groove 6 of the movable body 42, and the guide groove 8 extends obliquely along the circumferential direction of the slide groove 6. Therefore, when the cleaning member 43 moves axially along the connecting portion 431 relative to the movable body 42, the guide protrusion 7 moves circumferentially around the slide groove 6 under the guidance of the guide groove 8, so that the cleaning member 43 rotates relative to the movable body 42. It should be noted that when the guide protrusion 7 abuts against the end of the guide groove 8 away from the first telescopic power 441, the elastic member 5 abuts against the connecting portion 431 and is still in a compressed state. In order to facilitate assembly, the movable body 42 is spliced ​​in half.

[0038] Reference Figure 5 and Figure 7When the first telescopic power 441 drives the cleaning member 43 to move to the abutment portion 432 and abuts against the outer peripheral wall of the center roller 21 or the ice surface, the telescopic end of the first telescopic power 441 continues to extend a certain distance, so that the movable body 42 moves relative to the cleaning member 43, thereby driving the cleaning member 43 to rotate, so that the cleaning member 43 can pull and tear the entangled objects on the roller brush 2, or apply lateral shear force to the ice layer, thereby promoting the expansion of cracks and accelerating the disintegration of the ice layer.

[0039] Reference Figure 3 and Figure 4 In addition, the center roller 21 is evenly spaced along its circumference with support members 9, which correspond to the clearance cavity 14 one by one and are located in the clearance cavity 14, and are used to support the winding material and prevent the winding material from winding around the center roller 21. Specifically, each group of support members 9 includes two support bars 91, which are rectangular strips and made of hard material. Each support bar 91 is fixed on the outer peripheral wall of the center roller 21. The length of the support bar 91 extends along the axial direction of the center roller 21, and the width of the support bar 91 extends along the radial direction of the center roller 21. The width of the support bar 91 along the radial direction of the center roller 21 is smaller than the extension width of the bristles 22 along the radial direction of the center roller 21. The two support bars 91 in the same group are respectively located on both sides of the clearance cavity 14 away from each other along the circumference of the center roller 21. When the cleaning member 43 abuts against the center roller 21, it is located between the two support bars 91, so that the cleaning member 43 is misaligned with the support bar 91, so that the cleaning member 43 will not interfere with the support bar 91 when moving. Therefore, when the winding object on the roller brush 2 moves toward the center roller 21, it is restricted by the support bar 91 and is wound around the support bar 91, so that the cleaning member 43 can pass through the winding object and then pull it back to pull out the winding object. More importantly, when the roller brush 2 rotates to clean the floor, after the bristles 22 sweep the object to be cleaned into the clearance cavity 14, the support bar 91 can assist in pressing the object to be cleaned to push the object to be cleaned to the dust suction pipe 3.

[0040] The implementation principle of a road pavement cleaning and sanitation equipment in an embodiment of the present application is as follows: when the roller brush 2 is entangled by an entanglement, the roller brush 2 stops cleaning the road surface, and the cleaning mechanism 4 starts to clean the roller brush 2. Specifically, the cleaning member 43 enters each of the yielding cavities 14 one by one, hooks the entanglement through the barb 433 and pulls it outward, so that the blade of the barb 433 cuts the entanglement, and the fragments of the entanglement are sucked by the dust suction pipe 3. After the cleaning mechanism 4 finishes cleaning, it turns to the de-icing position, so that the roller brush 2 is not easy to interfere with the cleaning mechanism 4 when working. When the road surface is frozen, the cleaning mechanism 4 drives the cleaning member 43 to quickly reciprocate and knock the ice layer in the de-icing position to crack the ice layer, and then the roller brush 2 sweeps up the crushed ice and the dust suction pipe 3 sucks it in.

[0041] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
