The rotating shaft 6 is rotatably arranged on a rotating shaft support seat 7, and the end of the rotating shaft 6 is connected to the output end of the rotating drive device 3 through a clutch transmission assembly 8. The rotating shaft 6 and the rotating drive device 3 are both arranged on the rotating shaft support seat 7. A plurality of rotating cover opening hook plates 2 adapted to the ground cover are arranged on the rotating shaft 6. The rotating shaft support seat 7 is connected to the output end of the primary linear drive mechanism, and the primary linear drive mechanism is connected to the output end of the secondary linear drive mechanism. A sliding module 5 is arranged between the rotating shaft support seat 7 and the primary linear drive mechanism and the base 1.

The movement direction of the primary linear drive mechanism and the secondary linear drive mechanism is the same. The primary linear drive mechanism is used to drive the rotating shaft support seat 7 to move forward and backward, and the secondary linear drive mechanism is used to drive the primary linear drive mechanism and the rotating shaft support seat 7 to move forward and backward at the same time, so that several of the rotating cover opening hook plates 2 hook the cover plate and open the cover plate. Therefore, compared with the prior art, the utility model controls the shaft support seat 7 to move forward through the primary linear drive mechanism and the secondary linear drive mechanism, and the rotation drive device 3 drives the shaft 6 to rotate forward, so that the plurality of rotary cover-opening hook plates 2 hook the cover plate at the cover-opening station, and then controls the shaft support seat 7 to move backward in sequence through the primary linear drive mechanism and the secondary linear drive mechanism, thereby realizing the cover-opening process, and after the rotation drive device 3 drives the shaft 6 to reverse, the plurality of rotary cover-opening hook plates 2 can be separated from the cover plate, thereby avoiding the problem in the prior art that the suction cup cannot normally adsorb the cover for opening the cover due to inconsistent hardness and softness of the cover material, different fold positions, and deformation of the cover adsorption surface, thereby greatly improving the success rate of opening the cover, and improving production efficiency, and by adjusting the size and number of the plurality of rotary cover-opening hook plates 2, the cover-opening process for covers of different sizes can be realized, and compatibility with covers of different specifications is achieved, thereby greatly improving the practicality and application scope of the utility model.

[0020] like Figure 1 As shown, the rotation driving device 3 includes a stepping motor 31 and a reducer 32, and the output end of the stepping motor 31 is connected to the input end of the reducer 32. It can be seen that the reducer 32 is fixed to the rotating shaft support seat 7 through a support plate, and the reducer 32 transmits power to the clutch transmission assembly 8 after decelerating the stepping motor 31, thereby improving the stability of the utility model.

[0021] like Figure 2 As shown, in this embodiment, the sliding module 5 includes a first sliding module and two second sliding modules, the first sliding module is located between the two second sliding modules, the first sliding module includes a first sliding block 51 and a first linear slide rail 52 that are slidably matched, the two second sliding modules each include a second sliding block 53 and a second linear slide rail 54 that are slidably matched, the primary linear drive mechanism is connected to the first sliding block 51 through a first connecting plate 55, and the rotating shaft support seat 7 is respectively connected to the two second sliding blocks 53 through two second connecting plates 56. It can be seen that the rotating shaft support seat 7 is arranged at the active end of the primary linear drive mechanism and is slidably matched with the two second linear slide rails 54 through the two second sliding blocks 53, the primary linear drive mechanism is arranged at the active end of the secondary linear drive mechanism and is slidably matched with the first linear slide rail 52 through the first sliding block 51, the first linear slide rail 52 is located between the two second linear slide rails 54 and is fixed parallel to the upper end of the base 1, thereby improving the movement accuracy of the utility model.

[0022] like Figure 2 As shown, in the present embodiment, the primary linear drive mechanism comprises a primary cylinder 41, which is arranged on the first connecting plate 55 through a first cylinder mounting plate 43, and the output end of the primary cylinder 41 is connected to the side wall of the rotating shaft support seat 7, and the secondary linear drive mechanism comprises a secondary cylinder 42, which is arranged on the upper end of the base 1 through a second cylinder mounting plate 44, and the output end of the secondary cylinder 42 is connected to the first connecting plate 55 through a transmission plate 45, and the rotating shaft support seat 7 is driven by the primary cylinder 41, and the primary cylinder 41 is driven by the secondary cylinder 42, the first connecting plate 55 is detachably connected to the first slider 51 by screws, and the two second connecting plates 56 are respectively detachably connected to the two second sliders 53 by screws, thereby making the assembly and maintenance of the utility model more convenient.

[0023] like Figure 2 As shown, in this embodiment, a primary buffer 46 corresponding to the shaft support seat 7 is disposed on the upper end of the first connecting plate 55, and a secondary buffer 47 corresponding to the transmission plate 45 is disposed on the upper end of the base 1.

It can be seen that the active rotating push block 81 and the driven rotating block 82 are both cantilevered L-shaped blocks that are compatible with each other. The active rotating push block 81 outputs torque from the stepping motor 31 through the reducer 32. When the active rotating push block 81 rotates to contact the driven rotating block 82, the torque is transmitted to the rotating shaft 6 through the driven rotating block 82. It can be understood that the active rotating push block 81 and the driven rotating block 82 can both rotate freely along the axis of the rotating shaft 6. When the active rotating push block 81 is not in contact with the driven rotating block 82, the active rotating push block 81 and the driven rotating block 82 are in a separated state, that is, the torque cannot be transmitted at this time. When the active rotating push block 81 rotates to contact with the driven rotating block 82, the active rotating push block 81 and the driven rotating block 82 are in an engaged state, that is, the torque transmission can be achieved at this time.

It can be seen that the two induction sheets 83 are respectively at two positions when the active rotating push block 81 rotates, corresponding to the two position sensors 84 respectively, and when the stepping motor 31 rotates forward and reverse, the two induction sheets 83 trigger the two position sensors 84, and the two position sensors 84 control the stepping motor 31 to stop, thereby controlling the rotation position of the rotating cover opening hook plate 2, so that the rotating cover opening hook plate 2 is in contact with and separated from the ground cover, and the origin sensor 61 is used to feedback the rotation position of the rotating shaft 6, thereby improving the automation degree of the utility model.

[0026] like Figure 4 As shown, in this embodiment, two groups of rotating cover-opening hook plates 2 adapted to the ground cover are arranged on the rotating shaft 6, and the two groups of rotating cover-opening hook plates 2 each include a cover-opening plate 21 and a rotating shaft connecting seat 22, one end of the cover-opening plate 21 is connected to the rotating shaft 6 through the rotating shaft connecting seat 22, and a bent hook plate 23 extends from the other end of the cover-opening plate 21. It can be seen that the rotating shaft connecting seat 22 is detachably fixed to the rotating shaft 6 by screws, the cover-opening plate 21 and the hook plate 23 are integrally formed, and the hook plate 23 is used to hook the ground cover, and cooperate with the primary cylinder 41 and the secondary cylinder 42 to control the movement of the rotating shaft support seat 7, thereby realizing the process of opening the ground cover.

[0027] like Figure 4 As shown, in this embodiment, two support plates 71 are provided on the rotating shaft support seat 7, and both of the two support plates 71 are provided with bearings 72 adapted to the rotating shaft 6, so that the rotating shaft 6 can rotate more smoothly.

[0028] like Figure 1 As shown, in this embodiment, the axis direction of the rotating shaft 6 is perpendicular to the sliding direction of the sliding module 5. It can be seen that the axis direction of the rotating shaft 6 is perpendicular to the direction of the first linear slide rail 52 and the two second linear slide rails 54, further improving the stability of the utility model.
