Description

Technical Field

[0001] This utility model relates to the field of special vehicle technology, and in particular to a centrally mounted roller sweeping mechanism for a road sweeper. Background Technology

[0002] Currently, the centrally mounted sweeper uses a frame connected to a four-bar linkage mechanism, with the sweeper mechanism mounted on the hinge. The up-and-down movement of the sweeper is controlled by the movement of the hinge mechanism. This type of hinge mechanism has extremely poor overall stability and is very inconvenient to install in the central space of small and medium-sized vehicles. Another method uses a guide rail to drive the sweeper downhill in a straight up-and-down motion, but this type of mechanism is difficult to install and use due to the space limitations in the central space of small and medium-sized vehicles. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a centrally mounted roller sweeping mechanism for a road sweeper, which includes a fixed plate fixedly mounted on the vehicle frame, a transition plate fixedly connected to the fixed plate, a fixed bracket fixedly connected to the transition plate, a fixed bracket connected to a movable frame via a pin, a cylinder fixedly mounted on the movable frame, a rotating shaft sleeved inside the cylinder, snow roller seats fixedly mounted at both ends of the rotating shaft, a snow roller installed between the two snow roller seats, and a hydraulic motor mounted on any of the snow roller seats, the hydraulic motor being connected to the snow roller. The bottom of the fixed bracket is equipped with a swinging device for driving the movable frame to swing horizontally left and right, and the bottom of the movable frame is also equipped with a pitching device for driving the snow roll to swing up and down.

[0004] Based on the above scheme, the swing device includes a swing support fixedly installed on the movable frame, the swing support is hinged to the swing cylinder, and the other end of the swing cylinder is hinged to the fixed bracket. Based on the above scheme, the pitch device includes a notch on the cylinder, a shaft support lug fixedly connected to the shaft at the notch, the shaft support lug being hinged to the piston end of the pitch cylinder, a cylinder seat being fixedly welded to the movable frame, and the other end of the pitch cylinder being hinged to the cylinder seat.

[0005] Based on the above scheme, limit rings are installed at both ends of the cylinder.

[0006] Based on the above scheme, two identical swing devices are symmetrically arranged on both sides of the pitch device.

[0007] The beneficial effects of this utility model are: 1. The structure of connecting the fixed plate to the vehicle frame effectively avoids interference from the central drive shaft of small and medium-sized vehicles. The overall strength of the sweeping mechanism is high, the connection structure is simpler, and it is more convenient to manufacture and install.

[0008] 2. The snow roller is moved up and down by rotating the shaft driven by the pitch cylinder. The structure is lightweight and rigid, making it particularly suitable for small and medium-sized vehicles in environments with limited space.

[0009] 3. This device can be installed on other vehicle models and can be removed when not in use for easy operation. Attached Figure Description

[0012] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0013] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0014] exist Figures 1 to 3 A centrally mounted roller sweeper mechanism for a road sweeper includes a fixed plate 1, which is fixedly mounted on the vehicle frame. The fixed plate 1 is fixedly connected to a transition plate 2, and the transition plate 2 is fixedly connected to a fixed bracket 3. The fixed bracket 3 is connected to a movable frame 7 via a pin 4. A cylinder 8 is fixedly mounted on the movable frame 7, and a rotating shaft 10 is sleeved inside the cylinder 8. Snow roller seat plates 11 are fixedly mounted at both ends of the rotating shaft 10, and a snow roller 13 is installed between the two snow roller seat plates 11. A hydraulic motor 12 is mounted on any one of the snow roller seat plates 11, and the hydraulic motor 12 is connected to the snow roller 13. Furthermore, the bottom of the fixed bracket 3 is equipped with a swinging device for driving the movable frame 7 to swing horizontally left and right, and the bottom of the movable frame 7 is also equipped with a pitching device for driving the snow roller 13 to swing up and down.

[0015] The above technical solution eliminates the need for hinge mechanisms or guide rails to control the up-and-down movement of the snow roller 13. Instead, a fixed plate 1 and a fixed bracket 3 are used to install the snow roller 13, and a pitching device is used to control the up-and-down swing of the snow roller 13. This achieves the working and recovery states of the snow roller 13, which is simpler, easier to install, and more stable in operation than the previous solution.

[0016] Furthermore, the swing device includes a swing lug 6 fixedly mounted on the movable frame 7, the swing lug 6 being hinged to the swing cylinder 5, and the other end of the swing cylinder 5 being hinged to the fixed bracket 3. Using the above technical solution, the extension and retraction of the swing cylinder 5 is used to drive the movable frame 7 to rotate around the pin shaft 4, thereby controlling the horizontal swing angle of the snow roller 13 so that it can better adjust the sweeping angle.

[0017] Furthermore, the pitch device includes a notch on the cylinder 8, and a shaft support 14 fixedly connected to the shaft 10 is provided at the notch. The shaft support 14 is hinged to the piston end of the pitch cylinder 16. A cylinder seat 15 is fixedly welded to the movable bracket 7, and the other end of the pitch cylinder 16 is hinged to the cylinder seat 15.

[0018] By adopting the above technical solution, the extension and retraction of the pitch cylinder 15 drives the rotating shaft support 14 to rotate, which in turn drives the rotating shaft 10 to rotate inside the cylinder 8, thereby driving the snow roller 13 to be raised and lowered, making the structure simpler.

[0019] Furthermore, limit rings 9 are installed at both ends of the cylinder 8.

[0020] By adopting the above technical solution, the displacement of the rotating shaft 10 inside the cylinder 8 can be effectively prevented, resulting in better working stability.

[0021] Furthermore, two identical swing devices are symmetrically arranged on both sides of the pitch device.

[0022] See Figure 4 Using the above technical solution, the oil inlet of one swing cylinder 5 and the oil outlet of another swing cylinder 5 are connected to the oil inlet pipe through a tee, and its other oil outlet and oil inlet are connected to the oil return pipe through a tee. With this connection method, the two swing cylinders 5 can be extended and retracted by one through an operating valve, which has better synchronization and is easier to operate.

[0023] During operation, the snow roller 13 is lowered by the tilting cylinder 15 to perform its work, and the swinging cylinder 5 controls the swinging angle of the snow roller 13 to make its cleaning range wider. When not in operation, the snow roller is retracted by the tilting cylinder 15 to detach it from the bottom surface, making it easier for vehicles to pass.

[0024] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
