Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of sanitation vehicles, in particular to a bidirectional swing mechanism of a third side brush and a sanitation vehicle. Background Art

[0002] The side brush is a necessary device for sanitation vehicles to achieve cleaning and collection. The movement range of the side brush determines the cleaning range of the sanitation vehicle, and further determines the cleaning efficiency of the sanitation vehicle and its applicability in more cleaning environments. The side brush device includes two main side brushes symmetrically fixed on both sides of the sanitation vehicle and a third side brush connected to the frame of the sanitation vehicle. The third side brush is set on the same side as one of the main side brushes.

[0003] At present, the third side brush of most sanitation vehicles has a single cleaning function and a single range of motion. It is usually set on the right side and does not have the left side cleaning function. This is limited in some cleaning occasions and cannot accurately achieve the cleaning purpose. In addition, with the rapid development of domestic and foreign trade business and the expansion of overseas market business, facing the different driving habits of right-hand drive and left-hand drive in different countries, the cleaning disadvantages of existing sanitation vehicles have become more obvious, and the third side brush cannot effectively play a cleaning role.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The utility model discloses a Figure 1-6The bidirectional swing mechanism of the third side brush shown in the figure modifies the connection between the third side brush and the frame 5 from the fixed connection mode in the prior art to an articulated mode that can rotate along the horizontal plane. A driving cylinder 3 and a guide gas spring 4 are installed on the frame 5. The extension and retraction of the driving cylinder 3 provide power for the movement of the third side brush around the hinge point. At the same time, the guiding force of the guide gas spring 4 ensures that the third side brush can smoothly pass through the dead point during rotation, thereby providing guiding support force and auxiliary power for the smooth movement of the third side brush.

[0024] The third side brush includes a brush disc 1 at the end and a horizontally installed support rod 2. A straight-line frame-type adapter frame 7 is installed on the front side of the frame 5. The adapter frame 7 is hinged to the support rod 2 at the second hinge point 10 at the left end. A vertically upward upper support plate 8 is installed on the left side of the adapter frame. The left end of the upper support plate 8 protrudes from the leftmost end of the adapter frame 7. A first hinge point 11 is set at the left end of the upper support plate 8. The driving cylinder 3 is hinged at the first hinge point 11. The other end of the driving cylinder 3 is hinged to the upper surface of the support rod 2, and the hinge point between the driving cylinder 3 and the support rod 2 is located on the extension line of the support rod 2 from the frame 5 to the brush disc 1. The hinge points at both ends of the driving cylinder 3 are set vertically to the axis.

[0025] A third hinge point 12 is provided on the lower surface of the right end of the adapter frame 7, and the third hinge point 12 is used to hinge the guide air spring 4. The right side surface of the support rod 2 is connected to the side support plate 6, and the other end of the guide air spring 4 is hinged to the fourth hinge point 13 on the side support plate 6.

[0026] When the third side brush needs to be switched from the left side of the frame 5 to the right side, the guide gas spring 4 is in an extended state, and the driving cylinder 3 is extended to push the third side brush to rotate from the left side to the right side. During this rotation movement, the guide gas spring 4 connected to the side support plate 6 is compressed, and the fourth hinge point 13 and the third hinge point 12 are close to each other. When the guide gas spring 4 is compressed, the fourth hinge point 13 also makes a circular motion along the third hinge point 12. When the continuously compressed guide gas spring 4 happens to rotate to the third hinge point 12, the fourth hinge point 13 and the second hinge point 10 are located on the same straight line, as shown in FIG. Figure 3-4As shown, the guide gas spring 4 reaches the compression limit point, while the driving cylinder 3 has not yet reached the extension limit point. Therefore, as the driving cylinder 3 continues to extend, the third side brush continues to rotate to the right. At this time, the fourth hinge point 13 of the guide gas spring 4 rotates around the third hinge point 12 to the rotation limit, turns to the other side, and causes the guide gas spring 4 to rebound and extend. As the driving cylinder 3 drives the third side brush to continue to rotate, the movement relationship between the fourth hinge point 13 and the third hinge point 12 changes from being close to each other to being far away from each other, and a thrust is applied to the third side brush. The driving cylinder 3 stops when it reaches the extension limit. After the guide gas spring 4 passes the dead point, the third side brush is applied a force to the right by the guide gas spring 4. At this time, the driving cylinder 3 retracts, and when retracting, it drives the third side brush to continue to move in the direction in which the guide gas spring 4 extends, as shown in FIG. Figure 5-6 Therefore, the third side brush completes the conversion from left to right under the dual effects of the telescopic driving force of the driving cylinder 3 and the guidance of the guide gas spring 4.

[0027] The principle of the third side brush switching from right to left is the same as the above principle.

[0028] The utility model also discloses a sanitation vehicle, which is provided with the bidirectional swing mechanism of the third side brush of the sweeping brush as described above.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be 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 will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
