Description

Technical Field

[0001] The utility model relates to a road sweeper, in particular to a road sweeper with a new structure that is energy-saving and environment-friendly, and belongs to the technical field of sanitation machinery and equipment. Background Art

[0002] The working process of the road sweeper currently on the market is: first, the side brush sweeps the garbage on the road inward to the range that the main brush can sweep, then the main brush sweeps the garbage to the front of the suction cup, and finally the suction cup continuously sucks the garbage swept by the main brush into the on-board garbage bin. The suction cup of the existing road sweeper uses negative pressure suction to transfer garbage. Due to the large differences in the size and weight of garbage on the road, in order to suck it cleanly, it needs to be equipped with a high-power fuel engine to drive the fan for suction, which is not conducive to controlling the power consumption and emissions of the whole vehicle.

[0003] To this end, we hope to develop a pure electric road sweeper that is completely powered by on-board batteries, and abandon negative pressure suction as a method of garbage transportation, and instead use a combination of roller brush transportation and spiral transportation to transport garbage, so as to effectively reduce the power consumption and emissions of the entire vehicle.

[0007] When the road sweeper is working, during the driving process, the left and right garbage sweeping heads first rotate and brush the road and the curbs beside the vehicle body, and sweep the garbage from the left and right sides of the vehicle to the center line in front of the vehicle. Then, the left and right garbage rolling brushes further roll and sweep the road and sweep the garbage from the left and right sides of the bottom of the vehicle to the center line of the bottom of the vehicle. Finally, the garbage collection conveyor uses a combination of rolling brush conveying and spiral conveying to convey the garbage swept on the center line of the bottom of the vehicle upward to the on-board garbage bin for collection. Since the road sweeper does not need to use negative pressure suction to convey garbage and completely uses on-board batteries as power, it can effectively reduce the power consumption and emissions of the entire vehicle.

A worm gear reducer 26 is fixed on the upper fixed frame of the two support door frames 23.5. The worm gear reducer The output end of the machine 26 is fixedly connected to the upper end of the main shaft 18 of the chassis assembly, and the main shaft 18 is driven by the worm gear reducer 26 to rotate in situ; the lifting ring 25 is provided with a horizontally arranged thick-walled circular ring 25.1, and a radially extending connecting handle 25.2 is welded to the rear side of the outer circumference of the thick-walled circular ring 25.1. The inner circumference of the thick-walled circular ring 25.1 is respectively provided with fisheye joint bearings 25.3 on both sides of the front and rear sides through fixed support plates. The inner circumference of the thick-walled circular ring 25.1 is connected to a pair of limit tension springs 25.4 that extend obliquely to the upper and lower ends respectively on both sides of the two fisheye joint bearings 25.3, and the lower side of the thick-walled circular ring 25.1 is connected to a group of lower suspension chains evenly distributed along the circular ring. 25.5; the lifting ring 25 is movably connected to the two upward extending screws 23.4 of the middle support frame 23 through two fisheye joint bearings 25.3, and the upward extending screw 23.4 is sleeved with buffer springs 27 at the upper and lower ends of the corresponding fisheye joint bearings 25.3, and the upper part of the upward extending screw 23.4 is also provided with a pressing nut 28 to press the buffer spring 27, and the ends of each pair of limit tension springs 25.4 in the lifting ring 25 are respectively connected to the upper and lower ends of the door columns of the two supporting door frames 23.5, and the ends of each lower suspension chain 25.5 below the lifting ring 25 are respectively connected to the corresponding hanging ears on the top surface of the support plate 23.3, and the lower suspension chain 25.5 remains in a relaxed state.

[0040] The yaw lifting assembly is provided with a supporting platform 29 fixedly connected to the front end of the frame 1, and a vertical spindle 30 is fixedly provided on the top surface of the supporting platform 29. The spindle 30 is provided with an outer sleeve 31 rotatable around the spindle on the outer side of the spindle 30 through tapered roller bearings at the upper and lower ends. The lower end of the outer sleeve 31 is fixedly connected with a radially outward-extending first gear, and a second gear driven by a yaw drive motor 32 is also provided on one side of the supporting platform 29 to mesh with the first gear; an upper and lower connecting rod 33 is hinged on the upper part of the outer circumference of the outer sleeve 31, and the other ends of the two connecting rods 33 extend in parallel and are hinged to the end of the connecting handle 25.2 of the driving assembly lifting ring 25, and an electric push rod 34 is hinged on the lower part of the outer circumference of the outer sleeve 31 at a position directly below the hinge point of the corresponding connecting rod 33, and the push head of the electric push rod 34 is hinged to the middle part of the lower connecting rod 33; the horizontal yaw and up and down lifting of the entire garbage cleaning head are respectively controlled by the yaw drive motor 32 and the electric push rod 34.

[0041] Furthermore, the deflection lifting assembly is provided with a support plate 35 that can slide forward and backward through a slide rail under the support platform 29, and a boss is provided at the front end of the top surface of the support plate 35, and a positioning hole matching the boss is provided at the center of the bottom surface of the chassis 17 of the chassis assembly. When the garbage cleaning head 7 is not in use, it is lifted upward by the electric push rod 34, and then the support plate 35 is controlled to slide forward and extend, so that the boss is opposite to the positioning hole of the chassis, and the electric push rod 34 is slightly retracted to raise the garbage cleaning head 7 and fix it on the support plate 35 for storage.

[0042] When the garbage cleaning head 7 is working, the swing lifting assembly is controlled to make it swing to a suitable angle, and then lowered to make the supporting wheels of the chassis assembly touch the ground. Then, the rotary drive motor 8 transmits power to the worm gear reducers 26 of the left and right garbage cleaning heads 7, thereby driving the main shafts 18 of the left and right garbage cleaning heads 7 together with the brush sweeping assembly to rotate in the opposite direction, and each brush head module 20 of the brush sweeping assembly can perform road cleaning work. Since the plane of the rear half circle of the step limiting ring 24 is higher than the plane of the front half circle, when the upper pulley 21 of the brush head module 20 rolls to abut against the front half circle of the step limiting ring 24, the strip brush of the brush head module 20 is automatically pressed down so that the bristles touch the ground for brushing; when the upper pulley 21 of the brush head module 20 rolls to abut against the rear half circle of the step limiting ring 24, the strip brush of the brush head module 20 is automatically lifted up so that the bristles leave the ground. The rotating brushing and sweeping assembly can continuously sweep the garbage from the front side of the vehicle to the front center line of the vehicle. Moreover, when brushing, the bristles of the strip brush touch the ground more and more evenly, and it is not easy to miss any place. The bristles of the strip brush that extend obliquely can also effectively brush the corners of the curb beside the vehicle. Since the lifting ring 25 of the garbage cleaning head 7 is connected to the intermediate support frame 23 through a fisheye joint bearing 25.3, and is equipped with a buffer spring 27 and a limit tension spring 25.4, the garbage cleaning head 7 can adaptively deflect and rise and fall slightly according to the road conditions during operation, so it can easily cope with various rugged road conditions, ensuring stable operation while taking into account the cleaning effect. When a large depression appears on the road surface, the garbage cleaning head 7 can also be hung up by the lower suspension chain 25.5 to prevent it from falling into it.

[0043] like Figure 8-12 As shown, the garbage rolling brush 11 is provided with a support frame assembly and a 1# chain rolling brush 36.

[0044] The support frame assembly is provided with a support frame 37, and the left and right sides of the support frame 37 are respectively provided with a horizontal and transverse driving shaft 38 and a driven shaft 39 that can rotate in situ through a bearing frame, and the two ends of the driving shaft 38 and the driven shaft 39 are respectively fixedly connected with a 1# roller brush sprocket 40, and the four 1# roller brush sprockets 40 jointly support the 1# chain rolling brush 36, and a 1# roller brush driving motor 41 is provided in the support frame 37, and the 1# roller brush driving motor 41 drives the driving shaft 38 to rotate through the first chain transmission mechanism 42, thereby driving the 1# chain rolling brush 36 around the four 1# roller brush sprockets 40. The roller brush sprocket 40 rotates peripherally; two support feet 43 with adjustable support height and universal support wheels at the bottom are respectively provided on the front and rear sides of the support frame 37, and the support frame 37 is elevated and supported by four support feet 43; a horizontal and transverse L-shaped bracket 44 is respectively provided on the front and rear sides of the lower part of the support frame 37, and the two L-shaped brackets 44 are arranged front and back oppositely; a handle 45 that arches upward and crosses over the top of the 1# chain roller brush 36 is provided at the center of the upper left and right parts of the support frame 37, and two lifting ears for hanging the first vehicle-mounted small crane 12 are provided on the upper end of the handle 45.

[0045] The 1# chain rolling brush 36 is provided with two 1# vertical chain rings 46 at the front and rear sides, and the two 1# vertical chain rings 46 are respectively surrounded by the outer periphery of the two 1# rolling brush sprockets 40 at the front and rear sides and meshed, and a group of 1# brush sweeping modules 47 evenly spaced along the outer edges of the chain rings are spanned between the two 1# vertical chain rings 46. When the two 1# vertical chain rings 46 rotate, each 1# brush sweeping module 47 follows the 1# vertical chain ring 46 and moves synchronously; the 1# brush sweeping module 47 is provided with a strip base plate, and a straight brush with bristles extending to the outside of the chain ring is fixedly installed in the middle of the base plate, and the left and right sides of the base plate are fixedly mounted on the left and right sides of the base plate. Guide wheel brackets are installed at both ends, and in-situ rotatable transverse guide wheels and vertical guide wheels are mounted on the guide wheel brackets; when the 1# brush sweeping module 47 follows the 1# vertical chain ring 46 to the lower chain segment of the 1# vertical chain ring 46, the transverse guide wheels and vertical guide wheels on the guide wheel brackets at both ends of the 1# brush sweeping module 47 roll and lean against the two inner side surfaces of the L-shaped brackets 44 on the front and rear sides respectively, and the two L-shaped brackets 44 limit and support the 1# brush sweeping module 47, so that the 1# brush sweeping module 47 that walks to the lower part of the support frame 37 maintains the same horizontal height to brush the ground.

[0046] When the garbage rolling brush 11 is working, the first vehicle-mounted small crane 12 lowers it to the ground where the universal support wheel of the support leg 43 touches the ground, and then the 1# rolling brush driving motor 41 drives the 1# chain rolling brush 36 to rotate around the periphery of the four 1# rolling brush sprockets 40 of the support frame assembly, and the 1# brush sweeping module 47 that moves to the lower part of the support frame 37 moves from the side of the vehicle bottom to the center line of the vehicle bottom to clean the road surface. Since the support frame 37 is provided with L-shaped brackets 44 on the front and rear sides to limit and support the 1# brush sweeping module 47 that moves to the chain section under the 1# vertical chain ring 46, the 1# brush sweeping module 47 can be kept at the same horizontal height to brush the ground, and the bristles of the straight brush touch the ground evenly during brushing. By adjusting the support height of the support leg 43, the amount of the straight brush bristles touching the ground can also be changed to control the brushing force.
