Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, and particularly relates to a road cleaning device for municipal public works construction. Background Art

[0002] In the construction of municipal public works, road cleaning has always been an important link. Traditional methods usually adopt manual cleaning, combined with simple tools such as brooms and shovels. However, there are many deficiencies in this traditional method, such as low efficiency, high labor intensity, and poor cleaning effect.

[0003] In view of the above problems, some innovative methods have been adopted in recent years to improve the road cleaning efficiency through semi-automatic equipment. During operation, the garbage is swept onto the conveyor belt by the sweeping device, and the conveyor belt transports the garbage into the trash can. Since the conveyor belt needs to run at a relatively low inclination angle, the height and size of the trash can cannot be too large, otherwise it will greatly increase the size of the entire device and affect flexibility. If the size of the trash can is too small, it will lead to frequent removal of the garbage in the trash can, and the process is still cumbersome, affecting the road cleaning efficiency.

[0004] Therefore, a road cleaning device for municipal public works construction is needed. Summary of the Utility Model

[0005] An embodiment of the utility model provides a road cleaning device for municipal public works construction to solve the problems in the prior art.

[0006] The embodiment of the utility model adopts the following technical solution: A road cleaning device for municipal public works construction includes: a vehicle frame; a trash can installed at the rear end of the vehicle frame, and the upper end of the trash can is provided with an opening; a first conveyor belt arranged obliquely on the vehicle frame, and the included angle between the running direction of the pulley of the first conveyor belt and the plane of the vehicle frame chassis is controlled within 30°; a second conveyor belt fixedly installed above the vehicle frame chassis, and the included angle between the running direction of its pulley and the plane of the vehicle frame chassis is controlled within the range of 70° - 80°. A plurality of baffles are evenly arranged on the surface of the pulley of the second conveyor belt along its running direction, so that independent areas are formed between adjacent baffles. The lower end of the second conveyor belt is located at the higher end of the first conveyor belt and is used to receive the objects transported by the first conveyor belt. The higher end of the second conveyor belt is at least partially located above the trash can and is used to convey objects into the trash can.

[0007] Preferably, the higher end of the first conveyor belt is suspended on the vehicle frame through a first bracket and is rotatably connected to the first bracket. At least a part of the lower end of the first conveyor belt is connected to an angle adjustment component arranged on the vehicle frame, and the angle adjustment component is used to adjust the angle of the first conveyor belt.

[0008] Preferably, the angle adjustment assembly includes a linear drive source and a second bracket. The second bracket is fixedly installed above the lower end of the first conveyor belt. The linear drive source is located above the second bracket, and the base end of the linear drive source is hinged to the vehicle frame. The output shaft of the linear drive source is hinged to the second bracket. By operating the linear drive source, the lower end of the first conveyor belt is lifted or lowered.

[0009] Preferably, two sets of object sweeping assemblies driven by power to rotate are installed at the front end of the vehicle frame. The two sets of object sweeping assemblies rotate relative to each other to sweep the objects to be cleaned on the road surface onto the first conveyor belt.

[0010] Preferably, a dust suction device is also installed on the vehicle frame. One end of the dust suction pipe of the dust suction device is arranged at the front end of the vehicle frame and faces the road surface in front of the first conveyor belt. The other end of the dust suction pipe of the dust suction device is arranged at the opening of the trash can.

[0011] Preferably, a door that can be opened and closed is provided at the rear end of the vehicle frame.

[0012] Preferably, a handrail is also installed at the rear end of the vehicle frame.

[0013] The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0014] In the present invention, the lower inclination angle of the first conveyor belt is set to facilitate the smooth transition of objects from the first conveyor belt to the second conveyor belt. The relatively high inclination angle of the second conveyor belt is mainly to adapt to the height of the trash can, so as to ensure that when the trash can is at a relatively high height, the trash can can accommodate as many trash objects as possible. Through the transportation of the second conveyor belt and the cooperation of several baffles on the second conveyor belt, the swept trash objects can be smoothly transported into the trash can. Compared with using a single conveyor belt with a relatively low inclination angle, the size of the entire device can be greatly reduced. Compared with directly using a single conveyor belt with a relatively large inclination angle, it is convenient for workers or other automatic cleaning components to collect the trash on the road surface onto the conveyor belt.

Detailed embodiments

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the specific embodiments and corresponding drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0024] The following will, with reference to the drawings, detail the technical solutions provided by each embodiment of the present utility model.

[0025] Referring to Figures 1 to 5 As shown, an embodiment of the present utility model provides a road cleaning device for municipal public works construction, which includes a vehicle frame 1, a trash can 2, a first conveyor belt 3 and a second conveyor belt 4.

[0026] The vehicle frame 1 is made of metal and serves as the main body of the entire device. It has sufficient strength and stability to support the entire device. The trash can 2 is installed at the rear end of the vehicle frame 1, and the upper end of the trash can 2 is provided with an opening to facilitate receiving the objects conveyed from the second conveyor belt 4. The capacity of the trash can 2 is designed according to actual needs.

[0027] The first conveyor belt 3 is disposed obliquely on the vehicle frame 1, and the included angle between the running direction of the pulley of the first conveyor belt 3 and the plane of the vehicle frame 1 chassis is controlled within 30°. This relatively low inclination angle setting facilitates the smooth transition of objects from the first conveyor belt 3 to the second conveyor belt 4.

[0028] As Figure 2As shown in the figure, the second conveyor belt 4 is fixedly installed above the chassis of the vehicle frame 1, and the inner included angle between the running direction of its pulley and the plane of the chassis of the vehicle frame 1 is controlled within the range of 70°-80°. A number of baffles 41 are evenly arranged on the surface of the pulley of the second conveyor belt 4 along its running direction, so as to form independent areas between two adjacent baffles 41. The lower end of the second conveyor belt 4 is located at the higher end of the first conveyor belt 3 and is used to receive the objects transported by the first conveyor belt 3. The higher end of the second conveyor belt 4 is at least partially located above the trash can 2 and is used to convey objects into the trash can 2. The setting of the relatively high inclination angle of the second conveyor belt 4 is mainly to adapt to the height of the trash can 2, so as to ensure that when the trash can 2 is at a relatively high height, the trash can 2 can accommodate as many garbage objects as possible. Through the transportation of the second conveyor belt 4 and the cooperation of a number of baffles 41 on the second conveyor belt 4, the swept garbage objects can be smoothly transported into the trash can 2; compared with using a single conveyor belt with a relatively low inclination angle, the size of the entire device can be greatly reduced, and compared with directly using a single conveyor belt with a relatively large inclination angle, it is convenient for workers or other automatic cleaning components to collect the garbage on the road surface onto the conveyor belt. Therefore, the present application adopts the combination of the first conveyor belt 3 and the second conveyor belt 4, which can effectively solve the above problems.

[0029] In some embodiments, as Figures 2 to 4 shown, the higher end of the first conveyor belt 3 is suspended on the vehicle frame 1 through a first bracket 31 and is rotatably connected to the first bracket 31. The first bracket 31 is used to support the first conveyor belt 3, and the two can be rotatably connected through a hinge shaft, so that the first conveyor belt 3 can rotate around the first bracket 31.

[0030] As Figures 2 to 4 shown, the lower end of the first conveyor belt 3 is at least partially connected to an angle adjustment assembly 5 provided on the vehicle frame 1. The angle adjustment assembly 5 is used to adjust the angle of the first conveyor belt 3. In some practical applications, the angle adjustment assembly 5 includes a linear drive source 51 and a second bracket 52. The second bracket 52 is fixedly installed above the lower end of the first conveyor belt 3. The linear drive source 51 is located above the second bracket 52, and the base end of the linear drive source 51 is hinged to the vehicle frame 1 to ensure the stability and reliability of the drive source during movement. The output shaft of the linear drive source 51 is hinged to the second bracket 52. The design of the second bracket 52 is used to support the linear drive source 51 and be hinged to it, so that the movement of the linear drive source 51 can be effectively transmitted to the first conveyor belt 3. By operating the linear drive source 51, the lower end of the first conveyor belt 3 is driven to rise or fall, so as to realize the change of the working angle of the first conveyor belt 3.

[0031] And the angle change of the first conveyor belt 3 has at least the following effects:

[0032] First, when cleaning the garbage on the road, even some small particles of gravel and other objects, one end of the first conveyor belt 3 is as close to or as close to the ground as possible, so that the cleaned garbage can be smoothly moved to the first conveyor belt 3. In some practical applications, a guide plate made of rubber material can also be installed at the end of the first conveyor belt 3 (the guide plate is a prior art, not shown in the figure). By making the guide plate contact or close to the ground, it is convenient for staff or other automated cleaning components to smoothly clean the garbage on the road to the first conveyor belt.

[0033] Secondly, it prevents the first conveyor belt 3 from directly contacting the ground and causing excessive wear, and the cost of replacing small accessories such as guide plates due to wear can be further reduced.

[0034] In some practical applications, such as Figure 1 and Figure 3 As shown, two groups of sweeping components 6 driven to rotate by power are installed at the front side end of the frame 1, and the two groups of sweeping components 6 rotate relative to each other to sweep the objects to be cleaned on the road surface onto the first conveyor belt 3. As a prior art, the sweeping component 6 is mainly composed of a power drive device and a broom. The power drive device is an electric motor, which drives the broom to perform cleaning work by rotation. The broom is made of wear-resistant material and can effectively sweep up the objects to be cleaned on the road surface. The two groups of sweeping components 6 rotate in opposite directions, and this relative rotation method can effectively sweep up the objects to be cleaned on the road surface and push them onto the first conveyor belt 3.

[0035] In some practical applications, a dust suction device is also installed on the frame 1. One end of the dust suction pipe 7 of the dust suction device is arranged at the front end of the frame 1 and faces the road surface in front of the first conveyor belt 3. The other end of the dust suction pipe 7 of the dust suction device is arranged at the opening of the trash can 2. Some dust and lighter garbage objects can be directly sucked into the trash can 2 through the dust suction pipe 7.

[0036] Specifically, the rear side end of the frame 1 is provided with an openable and closable door body 11, which is mainly convenient for taking out the trash can 2. The rear side end of the frame 1 is also equipped with a handheld handrail 12, which is convenient for the staff to push the entire device to walk and move.

[0037] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
