[0002] Third side brushes are used in many sanitation vehicles whose primary function is street sweeping. They are mainly used to clean curbs or road areas that the left and right brushes cannot reach, or areas that are far from the left and right brushes. Currently, most third side brushes lack extension and angle adjustment functions, and most can only adjust the ground clearance, have a fixed angle, or no angle at all. This simple and manual operation limits the cleaning range. Not only can they not adapt to changing road conditions, but they are also tiring and laborious, which limits the cleaning effect and application scenarios of sanitation vehicles. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses an extension and tilting linkage mechanism for a third side brush and a sanitation vehicle. This mechanism has the function of automatically adjusting the extension length and tilt angle of the side brush, saving the time and effort of manual adjustment.

[0004] An extension and tilting linkage mechanism for a third side brush includes a frame, a horizontally extendable hydraulic cylinder connected to the frame, a swing rod connected to the output end of the hydraulic cylinder, a third side brush connected to the front end of the swing rod, a guide groove provided on the frame, the guide groove including a horizontal part and an inclined part that communicate with each other, the inclined part being closer to the end of the third side brush, and an angle adjustment part that cooperates with the guide groove on the side of the swing rod.

[0005] Preferably, a transition arc is provided between the horizontal portion and the inclined portion.

[0006] Preferably, the swing rod and the tilt adjustment part form a horizontally placed L-shaped structure, and the tilt adjustment part is the short side of the L-shaped structure.

[0007] Preferably, the hydraulic cylinder is also connected to a guide rod, which is arranged parallel to the swing rod.

[0008] Preferably, the frame is further provided with a linear bearing for providing a guide rail for the guide rod.

[0009] Preferably, the output end of the hydraulic cylinder is connected to a first adapter plate, the rear end of the guide rod is connected to the first adapter plate, the front end of the guide rod is connected to a second adapter plate, the swing rod is rotatably connected to the second adapter plate and passes through the front and rear sides of the second adapter plate, and the tilt adjustment part is located between the first adapter plate and the second adapter plate.

[0010] Preferably, the guide rods are at least two pieces evenly arranged along the circumference of the swing rod.

[0011] This utility model also discloses a sanitation vehicle, which includes an extension tilting linkage mechanism for the third side brush as described above.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This invention achieves the extension of the third side brush to different lengths through the extension and retraction of the hydraulic cylinder, and through the cooperation of the guide groove and the swing rod, the third side brush can rotate at a certain angle while extending, realizing the function of automatic control and adjustment of the third side brush, so that the cleaning range of the third side brush is wider.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Example 1

[0024] This utility model is disclosed as follows: Figure 1-7The diagram illustrates an extension and tilting linkage mechanism for a third side brush. This structure has a horizontally retractable hydraulic cylinder 2 mounted on a frame 1. The output end of the cylinder 2 is connected to a first adapter plate 8. Two guide rods 3 are connected forward from the top and bottom sides of the first adapter plate 8. The front ends of the two guide rods 3 are connected to a second adapter plate 9. Each guide rod 3 has a linear bearing 7 externally mounted on it. This linear bearing 7 is connected to the frame 1 and provides a guide track for the horizontal movement of the guide rod 3.

[0025] The swing rod 6 is a slender rod that passes forward through the second adapter plate 9 and is connected to a third side brush at its front end. A rotating bearing is provided between the swing rod 6 and the frame 1. The rear end of the swing rod 6 extends laterally to form a tilt adjustment part 4. When the swing rod 6 and the tilt adjustment part 4 are combined, they form a horizontal L-shaped structure, with the tilt adjustment part 4 being the short side of the L-shape. The guide rod 3 and the axis of the swing rod 6 are arranged parallel to each other. A guide groove 5 is provided on the frame 1. The guide groove 5 includes a horizontal part and an inclined part that are connected to each other. The horizontal part is a horizontal structure parallel to the axis of the guide rod 3 and the axis of the swing rod 6. The inclined part is a structure that extends downward along the horizontal part. A transition arc is provided between the horizontal part and the inclined part. The tilt adjustment part extends outward through the guide groove 5. When the oil cylinder 2 drives the first adapter plate 8 to move forward, under the connecting transmission action of the first adapter plate 8, guide rod 3, and second adapter plate 9, it drives the swing rod 6 to move forward, realizing the length extension action of the third side brush. At the same time, during the forward movement of the swing rod 6, the tilt adjustment part 4 moves to the tilting part under the guidance of the guide groove 5, driving the third side brush to rotate at a certain angle, that is, realizing the tilting movement of the third side brush.

[0026] Example 2

[0027] In this embodiment, the guide rod 3 consists of three or four pieces evenly arranged around the circumference of the swing rod 6, which are used to further stabilize the entire motion mechanism. The rest of the structure is the same as in Embodiment 1.

[0028] Example 3

[0029] This utility model also discloses a sanitation vehicle, wherein the chassis of the sanitation vehicle is equipped with an extension tilting linkage mechanism for the third side brush as described in Embodiment 1 or Embodiment 2.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. 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. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
