Description

Technical Field

[0001] This application relates to the technical field of sanitation vehicle sweeping mechanisms, and in particular to a sanitation vehicle sweeping mechanism with lifting and adjusting function. Background Technology

[0002] With continuous social development and progress, urbanization is increasing, and the number of streets is also growing, leading to a greater workload for street cleaning and sanitation. Sanitation sweepers are efficient road cleaning equipment; simply put, they are sweeping vehicles modified from specialized vehicle chassis to perform road sweeping functions. The sweeping brush mechanism is a crucial component of sanitation vehicles, and its performance directly affects the cleaning effect and work efficiency.

[0003] Regarding the aforementioned technologies, some shortcomings have been found in existing sanitation vehicle sweeping mechanisms. For example, the height of the sweeping brushes cannot be flexibly adjusted, making it difficult to adapt to different road conditions and cleaning needs. The swing angle of the sweeping brushes is inconvenient to adjust, making it impossible to expand or shrink the cleaning range according to actual conditions. In addition, some sweeping mechanisms have complex structures and high maintenance costs.

[0004] Therefore, it is necessary to design a new type of sanitation vehicle sweeping brush mechanism with lifting and adjusting function to solve the above problems. Utility Model Content

[0005] In order to achieve flexible adjustment and adaptability to different road conditions, this application provides a sanitation vehicle sweeping brush mechanism with lifting and adjusting function.

[0006] The technical solution provided in this application for a sanitation vehicle sweeping brush mechanism with lifting and adjusting features is as follows:

[0007] A sanitation vehicle sweeping brush mechanism with lifting and adjusting features includes a mounting frame. The mounting frame includes a top frame and a hanging frame. The hanging frame is slidably mounted in the top frame, and a hydraulic cylinder for adjusting the height of the hanging frame is fixedly mounted on the top frame. An equipment housing is fixedly mounted at the lower end of the hanging frame. Several swing frames are evenly mounted below the equipment housing. The swing frames are rotatably connected to the equipment housing, and a drive assembly for synchronously adjusting the rotation of all swing frames is installed in the equipment housing. A sweeping brush assembly is rotatably mounted on the lower end face of the swing frame, and a motor for driving the rotation of the sweeping brush assembly is fixedly mounted in the swing frame.

[0008] By adopting the above technical solution, and by setting up a mounting frame, hydraulic cylinder, swing frame, drive assembly, and sweeping brush assembly, the lifting and swing angle adjustment functions of the sweeping brush are realized. The hydraulic cylinder can flexibly adjust the height of the sweeping brush according to different road conditions and cleaning needs, so as to maintain a suitable distance between the sweeping brush and the ground and improve the cleaning effect. The drive assembly can drive all the swing frames to rotate synchronously, thereby changing the swing angle of the sweeping brush, expanding or shrinking the cleaning range, and enhancing the adaptability and flexibility of the sweeping brush mechanism.

[0009] Optionally, the top frame includes a transverse seat and a guide shell for sliding installation of the hanger. The guide shell is vertically installed at both ends of the transverse seat and is fixedly connected to the transverse seat.

[0010] By adopting the above technical solution, the top frame adopts a structural design of a transverse seat and a guide shell. The guide shell provides a stable guiding effect for the sliding of the hanger, ensuring that the hanger can maintain vertical movement during the lifting process, avoiding swaying and deviation, and improving the stability and reliability of the sweeping mechanism.

[0011] Optionally, the hanger includes a connecting plate and a positioning slider for fixed installation on the equipment housing. The positioning slider is installed at both ends of the connecting plate and is fixedly connected to the connecting plate.

[0012] By adopting the above technical solution, the connecting plate and positioning slider structure of the hanger enable the equipment shell to be firmly installed on the hanger. At the same time, the cooperation between the positioning slider and the guide shell further ensures the smooth sliding of the hanger in the top frame, making the lifting and lowering adjustment of the brush more stable.

[0013] Optionally, the device housing includes a strip-shaped shell and a side seat, the side seat being mounted on one side of the strip-shaped shell and fixedly connected to the strip-shaped shell.

[0014] By adopting the above technical solution, the strip-shaped shell and side mount design of the equipment housing provide a reasonable spatial layout for the installation of the swing frame and drive assembly. The strip-shaped shell can install multiple swing frames, enabling multiple brushes to work simultaneously and improving cleaning efficiency. The side mount provides support points for the installation and connection of the drive assembly, facilitating the operation and control of the drive assembly.

[0015] Optionally, the swing frame includes a frame rod and a cover, with the middle part of the swing frame rotatably mounted on the strip-shaped shell, and the cover fixedly mounted on the lower end face of the frame rod.

[0016] By adopting the above technical solution, the swing frame's support rod and cover structure, with the support rod serving as the main swinging component, can drive the sweeping brush assembly to swing. The cover protects the sweeping brush assembly, preventing debris from splashing onto it during cleaning, thus affecting its normal operation and extending its service life.

[0017] Optionally, the drive assembly includes a linkage rod and an electric cylinder, the end of which is rotatably connected to a side seat, and the linkage rod is rotatably connected to the output end of the electric cylinder.

[0018] By adopting the above technical solution, the drive component uses a combination of linkage rods and electric cylinders. The electric cylinders, as the power source, can precisely control the movement of the linkage rods, thereby achieving synchronous rotation adjustment of all swing frames. This structure is simple, reliable, easy to operate and maintain, and improves the automation level of the sweeping mechanism.

[0019] Optionally, a connecting shaft is fixedly installed at the head of the frame rod, and a plurality of connecting holes that cooperate with the connecting shaft are evenly opened on the linkage rod.

[0020] By adopting the above technical solution, the connecting shaft at the head of the frame pole matches the connecting hole on the linkage rod, ensuring that the linkage rod can accurately drive the frame pole to rotate, thus achieving synchronous adjustment of the swing frame. This connection method is stable and reliable, effectively transmitting power and ensuring the accuracy of the brush swing angle adjustment.

[0021] Optionally, the brush assembly includes a base plate and stiff bristles, the stiff bristles being evenly installed on the lower end face of the base plate along the circumferential direction, and the stiff bristles being fixedly connected to the base plate.

[0022] By adopting the above technical solution, the base plate and hard bristles of the sweeping brush assembly are designed so that the hard bristles are evenly installed on the base plate along the circumference. When the sweeping brush assembly rotates, the hard bristles can fully cover the cleaning area, improving the cleaning effect. The hard bristles have strong wear resistance and cleaning ability, and can effectively remove dust, debris, and other contaminants from the ground.

[0023] In summary, this application includes at least one of the following beneficial technical effects: By adjusting the height and swing angle of the sweeping brush, this application enables the sweeping brush to maintain a suitable distance and angle from the ground, adapting to different road conditions and cleaning needs, comprehensively and efficiently cleaning dust, debris, etc., on the ground, thus improving cleaning quality. The height and swing angle of the sweeping brush can be flexibly adjusted according to actual conditions, expanding or shrinking the cleaning range, suitable for cleaning roads of different widths and shapes, enhancing the adaptability and flexibility of the sweeping brush mechanism. The design of multiple sweeping brushes working simultaneously, combined with the swing angle adjustment function, enables the completion of cleaning tasks covering larger areas in a shorter time, improving the working efficiency of sanitation vehicles and saving manpower and time costs.

The stiff bristles 62 have strong wear resistance and cleaning ability, effectively cleaning dust, debris, and other contaminants from the ground.

[0040] The implementation principle of a sanitation vehicle sweeping brush mechanism with lifting and adjusting function according to an embodiment of this application is as follows: When the height of the sweeping brush needs to be adjusted, the hydraulic cylinder 2 is activated, and the piston rod of the hydraulic cylinder 2 extends and retracts, causing the hanger 12 to slide in the guide shell 112 of the top frame 11, thereby realizing the lifting and adjusting of the sweeping brush assembly 6. When the swing angle of the sweeping brush needs to be adjusted, the electric cylinder 52 is activated, and the output end of the electric cylinder 52 pushes the linkage rod 51 to move. The linkage rod 51 drives all the swing frames 4 to rotate synchronously through the connecting shaft 411, changing the swing angle of the sweeping brush. During the sweeping process, the motor drives the sweeping brush assembly 6 to rotate, and the hard bristles 62 sweep the ground.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
