Description

Technical Field

[0001] This utility model relates to the field of road cleaning technology, specifically to a vacuum sweeper for road cleaning. Background Technology

[0002] In the maintenance and upkeep of roads, in order to maintain road performance, ensure driving safety, comfort and smooth flow, and save transportation costs and time, it is necessary to clean the roads regularly. With the advancement of technology, road cleaning is now carried out by sweeper trucks, which can sweep and vacuum the road surface.

[0003] Existing vacuum sweepers simply rotate and sweep the ground, failing to collect and gather dust. Furthermore, the sweeping angle is not adjustable, reducing the cleaning effect and failing to assist with subsequent vacuuming. During vacuuming, the lack of dust coverage can easily lead to missed areas, further diminishing the vacuuming efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned above, such as the inability to sweep and gather dust, the inability to adjust the sweeping angle, which reduces the sweeping effect, and the easy omissions during vacuuming, which also reduces the vacuuming effect. This utility model provides a vacuum sweeper for road cleaning.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A road sweeping vacuum sweeper includes a mounting frame and a suction cylinder. The suction cylinder is fixedly connected to the right side of the mounting frame. A sweeping assembly is disposed inside the mounting frame. A cover plate is hinged to the top of the suction cylinder. A vacuum cleaner is placed inside the suction cylinder. A suction assembly is disposed below the vacuum cleaner at the bottom of the suction cylinder. Wheels are symmetrically fixedly mounted on the front and rear sides of the bottom left side of the mounting frame. A drive omnidirectional wheel is fixedly mounted at the center of the bottom right side of the suction cylinder.

[0006] Furthermore, the cleaning assembly includes a hydraulic cylinder. A hydraulic cylinder is fixedly installed at the center of the top of the mounting frame. A telescopic rod is driven and connected to the center of the inside of the hydraulic cylinder. The telescopic rod extends downward. A horizontal plate is fixedly installed at the bottom of the telescopic rod. Mounting seats are symmetrically fixedly installed at the front and rear ends of the horizontal plate. Limiting posts are symmetrically fixedly installed at the left and right ends of the mounting seats. A connecting cylinder is rotatably connected to the inner side of the mounting seat. A cleaning disc is inserted into the bottom of the connecting cylinder. A motor compartment is fixedly installed at the top of the connecting cylinder. A sleeve is sleeved on the outer side of the top of the telescopic rod. A second telescopic rod is symmetrically driven and connected to the front and rear sides of the inside of the hydraulic cylinder. The bottom ends of the second telescopic rods are fixedly installed with the sleeves. A transmission rod is driven and connected between the front and rear sides of the sleeve and the side of the motor compartment.

[0007] Furthermore, the limiting post extends to the left and right sides into the interior of the mounting frame, and the horizontal plate and the mounting seat are slidably connected inside the mounting frame by means of the limiting post. Therefore, the horizontal plate and the mounting seat can be moved up and down by means of the telescopic rod.

[0008] Furthermore, the hydraulic cylinder employs independent pipeline control for telescopic rod one and telescopic rod two to drive them to extend and retract individually.

[0009] Furthermore, there are two transmission rods. One end is hinged to the front and rear sides of the sleeve, and the other end is hinged to the motor compartments on the front and rear sides after being symmetrically unfolded downwards. Therefore, by moving the sleeve up and down, the tilt angle of the connecting cylinders on the front and rear sides can be adjusted synchronously using the transmission rods.

[0010] Furthermore, the suction assembly includes a suction frame, the bottom of the suction cylinder is slidably connected to the suction frame, and the suction frame is connected to the vacuum cleaner inside the suction cylinder. A slanted frame is fixedly installed on the rear side inside the suction frame. The left end face of the slanted frame and the inside of the suction frame form a main suction chamber. A secondary suction chamber is opened inside the slanted frame, and the secondary suction chamber is also connected to the vacuum cleaner inside the suction cylinder. A roller is slidably connected to the bottom right end of the slanted frame.

[0011] Furthermore, an upward-sloping opening is provided on the left side of the bottom of the suction frame, so that dust on the ground can enter the bottom of the inner cavity of the suction frame through the opening during the movement of the mounting frame and the suction cylinder.

[0012] Furthermore, the middle part of the inclined frame adopts a corrugated soft connection design, which allows the bottom of the inclined frame to tilt and rotate. With the help of the rollers at the bottom of the inclined frame, the inclined frame can tilt and rotate after the bottom of the inclined frame contacts the ground.

[0013] The beneficial effects of this utility model are as follows: This invention, through the design of symmetrically tilted sweeping discs on both the front and rear sides of the sweeping assembly, enables the sweeping discs to sweep the ground while simultaneously gathering dust towards the center during the rotation driven by the motor. This facilitates subsequent vacuuming. The tilt angle of the sweeping discs can also be adjusted, improving the cleaning effect. Furthermore, the design of the suction assembly effectively blocks and sucks up dust, preventing dust accumulation and missed areas, thus enhancing the overall vacuuming efficiency.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] A preferred embodiment of the present invention, a road sweeping vacuum sweeper, will be described in detail below, such as... Figures 1-3 As shown, a road sweeping vacuum sweeper includes a mounting frame 1 and a suction cylinder 2. The suction cylinder 2 is fixedly connected to the right side of the mounting frame 1. A sweeping component 3 is provided inside the mounting frame 1. A cover plate 4 is hinged to the top of the suction cylinder 2. A vacuum cleaner is placed inside the suction cylinder 2. A suction component 5 is provided below the vacuum cleaner at the bottom of the suction cylinder 2. Travel wheels 6 are symmetrically fixedly installed on the front and rear sides of the bottom left side of the mounting frame 1. A drive universal wheel 7 is fixedly installed at the center of the bottom right side of the suction cylinder 2.

[0018] Furthermore, such as Figures 3-6As shown, the cleaning assembly 3 includes a hydraulic cylinder 31. The hydraulic cylinder 31 is fixedly installed at the center of the top of the mounting frame 1. A telescopic rod 32 is connected to the center of the inside of the hydraulic cylinder 31. The telescopic rod 32 extends downward and a horizontal plate 33 is fixedly installed at the bottom end of the telescopic rod 32. Mounting seats 34 are symmetrically fixedly installed at the front and rear ends of the horizontal plate 33. Limiting posts 35 are symmetrically fixedly installed at the left and right ends of the mounting seats 34. The limiting posts 35 extend to the left and right sides into the inside of the mounting frame 1. The horizontal plate 33 and the mounting seats 34 are slidably connected inside the mounting frame 1 by the limiting posts 35. Therefore, the horizontal plate 33 and the mounting seats 34 can be moved up and down by the action of the telescopic rod 32.

[0019] The inner side of the mounting base 34 is rotatably connected to a connecting cylinder 36. The bottom of the connecting cylinder 36 is inserted into a cleaning disc 37. The top of the connecting cylinder 36 is fixedly installed with a motor compartment 38. The outer side of the top of the telescopic rod 32 is sleeved with a sleeve disc 39. The front and rear sides of the hydraulic cylinder 31 are symmetrically connected to the telescopic rod 310, and the bottom of the telescopic rod 310 is fixedly installed with the sleeve disc 39. The hydraulic cylinder 31 uses independent pipeline control for the telescopic rod 32 and the telescopic rod 310 to drive the telescopic rod 32 and the telescopic rod 310 to move independently.

[0020] The front and rear sides of the sleeve 39 are connected to the sides of the motor compartment 38 by transmission rods 311. There are two transmission rods 311. One end is hinged to the front and rear sides of the sleeve 39, and the other end is hinged to the motor compartment 38 on the front and rear sides after being symmetrically unfolded downward. Therefore, by moving the sleeve 39 up and down, the tilt angle of the connecting cylinders 36 on the front and rear sides can be adjusted synchronously by using the transmission rods 311.

[0021] When the tilt angle of the sweeping disc 37 needs to be adjusted according to different sweeping requirements and different specifications of the sweeping disc 37, the hydraulic transmission action of the hydraulic cylinder 31 and the first telescopic rod 32 can drive the horizontal plate 33 and the mounting base 34 to move up and down, thereby driving the connecting cylinder 36 and the sweeping disc 37 to adjust up and down. The hydraulic transmission action of the hydraulic cylinder 31 and the second telescopic rod 310 can drive the sleeve 39 to move up and down. During the up and down movement of the sleeve 39, through the action of the transmission rod 311 between the sleeve 39 and the motor compartment 38, and in conjunction with the limiting rotation connection between the connecting cylinder 36 and the inner side of the mounting base 34, the connecting cylinders 36 on both the front and rear sides can be rotated and adjusted synchronously, thereby realizing the adjustment of the tilt angle of the sweeping disc 37.

[0022] Furthermore, such as Figures 7-8As shown, the suction assembly 5 includes a suction frame 51, and the suction cylinder 2 is slidably connected to the bottom of the suction frame 51. The suction frame 51 is connected to the vacuum cleaner inside the suction cylinder 2. The bottom left side of the suction frame 51 has an upwardly sloping opening, so that when the mounting frame 1 and the suction cylinder 2 move, the dust on the ground can enter the bottom of the inner cavity of the suction frame 51 through the sloping opening.

[0023] An inclined frame 52 is fixedly installed on the rear side inside the suction frame 51. The left end face of the inclined frame 52 and the inside of the suction frame 51 form a main suction chamber 53. An auxiliary suction chamber 54 is opened inside the inclined frame 52, and the auxiliary suction chamber 54 is also connected to the vacuum cleaner inside the suction cylinder 2. A roller 55 is connected to the bottom right side of the inclined frame 52. The middle part of the inclined frame 52 adopts a corrugated soft connection design, which allows the bottom of the inclined frame 52 to tilt and rotate. With the roller 55 at the bottom of the inclined frame 52, the inclined frame 52 can tilt and rotate after the bottom of the inclined frame 52 contacts the ground.

[0024] With the bendable design of the inclined frame 52, the bottom right end of the inclined frame 52 is close to the ground. The rollers 55 at the bottom of the inclined frame 52 allow the inclined frame 52 to move better on the ground. The inclined frame 52 can block dust, so that the dust is better located in the main suction chamber 53 between the left end of the inclined frame 52 and the suction frame 51. The dust is then better sucked up by the vacuum cleaner. The dust blocked by the inclined frame 52 can also be sucked up through the secondary suction chamber 54 inside the inclined frame 52, avoiding the accumulation of dust and the omission of dust.

[0025] The working principle of this utility model is as follows: During cleaning, the mounting frame 1 and the suction cylinder 2 are moved forward in the direction of the mounting frame 1 by the action of the walking wheels 6 and the drive casters 7.

[0026] During the movement of the mounting frame 1 and the suction cylinder 2, the motor inside the motor compartment 38 is activated to drive the sweeping disc 37 at the bottom of the connecting cylinder 36 to rotate. Through the symmetrical tilting design of the sweeping discs 37 on the front and rear sides, the sweeping discs 37 can sweep the ground while also gathering the dust on the road surface in the middle between the sweeping discs 37 on the front and rear sides during the rotation.

[0027] Simultaneously, the vacuum cleaner inside the suction cylinder 2 is activated. Due to the bendable design of the inclined frame 52, the bottom right end of the inclined frame 52 is close to the ground. With the help of the rollers 55 at the bottom of the inclined frame 52, the inclined frame 52 can move better on the ground. Through the action of the inclined frame 52, dust can be blocked, so that the dust is better located in the main suction chamber 53 between the left end of the inclined frame 52 and the suction frame 51. With the action of the vacuum cleaner, the dust can be better sucked up. Since the dust blocked by the inclined frame 52 can also be sucked up through the secondary suction chamber 54 inside the inclined frame 52, the accumulation of dust and the omission of suction are avoided.

[0028] When the tilt angle of the sweeping disc 37 needs to be adjusted according to different sweeping requirements and different specifications of the sweeping disc 37, the hydraulic transmission of the hydraulic cylinder 31 and the first telescopic rod 32 can drive the horizontal plate 33 and the mounting base 34 to move up and down, thereby driving the connecting cylinder 36 and the sweeping disc 37 to adjust up and down. The hydraulic transmission of the hydraulic cylinder 31 and the second telescopic rod 310 can drive the sleeve 39 to move up and down. During the up and down movement of the sleeve 39, through the action of the transmission rod 311 between the sleeve 39 and the motor compartment 38, and in conjunction with the limiting rotation connection between the connecting cylinder 36 and the inner side of the mounting base 34, the connecting cylinders 36 on both the front and rear sides can be rotated and adjusted synchronously, thereby realizing the adjustment of the tilt angle of the sweeping disc 37.

[0029] After cleaning is completed, the cleaning disc 37 can be lifted up and removed from the ground to stop its use.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
