[0029] The driving sleeve 13 is provided with a control section and a driving section in sequence from top to bottom. The control section and the driving section are designed to be integrally formed. The control section is cylindrical, and the driving section is truncated cone-shaped. The upper end diameter of the driving section is larger than the lower end diameter of the driving section, and the lower end diameter of the control section is not smaller than the upper end diameter of the driving section.

[0030] A plurality of clamping rods 11 are distributed in a ring array about the center of the connecting disk 6 .

[0031] The working principle and beneficial effects of the above technical solution are as follows: a cleaning mechanism 2 is arranged at the bottom of the cleaning and sweeping vehicle 1, and the cleaning mechanism 2 includes a motor 3. The motor 3 can adopt a DC brushless motor 3 commonly used in existing cleaning vehicles. The motor 3 is mounted on a mounting bracket 4, and the mounting bracket 4 is fixedly connected to the bottom of the cleaning and sweeping vehicle 1. The output end of the motor 3 is fixedly connected to a fixing seat 5, one end of a connecting column 8 is fixedly connected to the fixing seat 5, and the other end is fixedly connected to the center of the mounting hole 7. When the output end of the motor 3 rotates, the fixing seat 5 can be driven to rotate, and the rotation of the fixing seat 5 drives the connecting column 8 and the connecting plate 6 to rotate, and the connecting plate 6 The sweeping disc 10 is driven to rotate by the cooperation of the clamping rod 11 and the clamping hole 12, so that the sweeping operation can be carried out. When the sweeping disc 10 needs to be replaced, the driving sleeve 13 is pushed upward, and the driving sleeve 13 can slide upward along the outer wall of the connecting column 8, so that the driving sleeve 13 is away from the mounting hole 7, and then the clamping rod 11 can be pulled to separate the clamping rod 11 from the clamping hole 12, so that the sweeping disc 10 can be separated from the connecting disc 6, so as to replace the damaged sweeping disc 10; when installing a new sweeping disc 10, first align the connecting hole 9 of the new sweeping disc 10 with the connecting disc 6, and then install the sweeping disc 10 To the connecting plate 6, the connecting plate 6 is in the connecting hole 9, the sweeping plate 10 is rotated to adjust the angle of the sweeping plate 10 so that the sliding hole is aligned with the clamping hole 12, and then the driving sleeve 13 is pushed downward. Since the driving section at the lower end of the driving sleeve 13 is truncated, the outer wall of the lower end of the driving sleeve 13 gradually contacts the end of the clamping rod 11 close to the connecting column 8, and pushes the clamping rod 11 to slide in the sliding hole toward the clamping hole 12 until the end of the clamping rod 11 away from the connecting column 8 is inserted into the clamping hole 12. At this time, the sweeping plate 10 is installed on the connecting plate 6, and the clamping rod 11 is aligned with the driving sleeve 13. The limiter is placed near one end of the connecting column 8 to prevent the clamping rod 11 from being detached from the clamping hole 12, thereby improving the reliability of the connection between the connecting disk 6 and the sweeping disk 10. In the utility model, the sweeping disk 10 can be quickly disassembled by separating the clamping rod 11 from the clamping hole 12, and a new sweeping disk 10 can be quickly installed by cooperating with the clamping rod 11 and the clamping hole 12, thereby completing the rapid replacement of the damaged sweeping disk 10, which is more time-saving and labor-saving. In the process of replacing the sweeping disk 10, no special tools are required, and there is no need to remove a large number of bolts, which reduces the labor intensity of the staff and is more practical.

[0032] Example 2

[0033] On the basis of the above-mentioned embodiment 1, Figure 1 , Figure 3 As shown, a ball 14 is disposed at one end of the clamping rod 11 close to the driving sleeve 13 , and the ball 14 abuts against the outer wall of the lower end of the driving sleeve 13 .

[0034] The working principle and beneficial effects of the above technical solution are as follows: the ball 14 is arranged at the end where the clamping rod 11 contacts the driving sleeve 13. The ball 14 contacts the outer wall of the lower end of the driving sleeve 13. When the driving sleeve 13 moves toward the mounting hole 7, the ball 14 rolls along the outer wall of the lower end of the driving sleeve 13. The rolling friction replaces the sliding friction, thereby reducing the wear of the clamping rod 11 and extending the service life of the clamping rod 11 and the driving sleeve 13.

[0035] Example 3

[0036] On the basis of Example 1 or 2, Figure 1 , Figure 3 As shown, a baffle 15 is provided on the outer wall of one end of the clamping rod 11 close to the driving sleeve 13 , and a reset spring 16 is sleeved on the clamping rod 11 , one end of the reset spring 16 is connected to the inner wall of the connecting hole 9 , and the other end of the reset spring 16 is connected to the side wall of the baffle 15 .

[0037] The working principle and beneficial effects of the above technical solution are as follows: when the drive sleeve 13 is lifted upward, under the action of the reset spring 16, the end of the clamping rod 11 close to the connecting column 8 is always in contact with the outer wall of the drive sleeve 13 through the ball 14, so that the clamping rod 11 can slide in the direction away from the clamping hole 12, thereby realizing the automatic separation of the clamping rod 11 and the clamping hole 12. There is no need to manually pull the clamping rod 11. After the clamping rod 11 is separated from the clamping hole 12, the sweeping disc 10 is automatically separated from the connecting disc 6, making the replacement of the sweeping disc 10 more convenient and quick.

[0038] Example 4

[0039] On the basis of any one of Examples 1-3, Figure 1 As shown, a compression spring 17 is sleeved on the outer wall of the connecting column 8 , one end of the compression spring 17 is connected to the lower surface of the fixing seat 5 , and the other end of the compression spring 17 is connected to the upper surface of the driving sleeve 13 .

[0040] The working principle and beneficial effects of the above technical solution are as follows: under the action of gravity, the driving sleeve 13 can slide into the mounting hole 7 and limit the clamping rod 11. In order to improve the stability of the driving sleeve 13, a compression spring 17 is arranged between the driving sleeve 13 and the fixing seat 5. The driving sleeve 13 is pressed into the mounting hole 7 by the compression spring 17 to prevent the driving sleeve 13 from sliding upward during the rotation of the sweeping disc 10 and causing the clamping rod 11 to separate from the clamping hole 12, thereby improving the reliability of the connection between the sweeping disc 10 and the connecting disc 6. When replacing the sweeping disc 10, it is only necessary to push the driving sleeve 13 upward, the compression spring 17 is further compressed, the reset spring 16 is reset, and the sweeping disc 10 is automatically separated from the connecting disc 6.

[0041] Example 5

[0042] On the basis of any one of Examples 1-4, Figure 4As shown, a guide bar 18 is disposed on the outer wall of the connection plate 6, and a guide groove 19 matched with the guide bar 18 is disposed on the inner wall of the connection hole 9, and the outer wall of the guide bar 18 and the inner wall of the guide groove 19 are slidably connected up and down.

[0043] The working principle and beneficial effects of the above technical solution are as follows: in order to accurately install the sweeping disc 10, a guide groove 19 is set on the inner wall of the connecting hole 9 of the sweeping disc 10. When installing the sweeping disc 10, first align the guide groove 19 of the sweeping disc 10 with the guide bar 18 on the outer wall of the connecting disc 6. The guide bar 18 slides in along the guide groove 19, so that the bottom wall of the connecting disc 6 contacts the bottom wall of the connecting hole 9. At this time, the snap-in hole 12 is aligned with the sliding hole, so that the sweeping disc 10 can be quickly installed.

[0044] Example 6

[0045] On the basis of any one of Examples 1-5, Figure 3 As shown, the outer wall of the upper end of the driving sleeve 13 is sleeved with an anti-skid sleeve 20, and the outer wall of the anti-skid sleeve 20 is provided with a plurality of transverse anti-skid grooves.

[0046] The working principle and beneficial effects of the above technical solution are as follows: an anti-skid sleeve 20 made of anti-skid material is arranged on the outer wall of the driving sleeve 13, and anti-skid patterns are arranged on the outer wall of the anti-skid sleeve 20, which can increase the friction of the outer wall of the anti-skid sleeve 20 and is less likely to slip, thereby facilitating the driving sleeve 13 to slide up and down along the outer wall of the connecting column 8, thereby realizing the rapid replacement of the sweeping disc 10.

[0047] Example 7
