The upper portion of the upper connecting portion 10 can be vertically slidably inserted into the groove, the bottom of the groove is connected with the upper surface of the upper connecting portion 10 through a plurality of vertically arranged heavy springs 20, and the elasticity of the heavy springs 20 enables the upper connecting portion 10 to not completely slide out of the notch of the groove when suspended, so that the stability of the structure is guaranteed. The bottom end face of the upper connecting portion 10 is a concave spherical surface-shaped concave face, the interior of the concave spherical surface-shaped concave face is closely matched with the lower rolling body 9 with a spherical convex face, the upper connecting portion 10 is attached to the upper portion of the lower rolling body 9, free sliding within a certain range can be achieved, the specific sliding range is set as required, and when the upper connecting portion is contacted with the bottom face and rolled, enough freedom degree can be achieved, clamping stagnation and damage during vibration can be avoided. The lower rolling body 9 and the upper connecting part 10 are preferably made into a detachable connecting structure, so that the two parts can slide relatively to realize free sliding in a three-dimensional space, can not be separated during sliding, and can rotate to a certain degree under the action of the driving motor 3; during specific implementation, the upper connecting part 10 can be connected with the lower rolling body 9 through magnetism, permanent magnets or electromagnetic connection is adopted, for example, the electromagnet is connected, one of the permanent magnets or the electromagnetic connection is internally provided with the electromagnet, and the magnetism enables the upper connecting part 10 to slip relative to the lower rolling body 9, namely, certain free end sliding is realized.

A power motor 18 is arranged near one of the two support legs 13, the power motor 18 drives the rotating shaft 6 to rotate through the transmission bevel gear so as to intermittently impact the bottom of the groove of the machine shell 1, and the power motor 18 and the heavy spring 20 realize vibration. As an embodiment, in order to protect the heavy-duty spring 20 during long-term idle or transportation, a connecting rod is vertically fixed on the extending rod 14 of the other leg 13, a vertically arranged rack 16 is fixed on the connecting rod, the rack 16 is meshed with the gear of the cylinder 4, so that the top support 8 on the torsion rod 5 lifts the machine shell 1 upwards to release the heavy-duty spring 20 when the leg 13 is extended, and the heavy-duty spring 20 is prevented from being in a large-amplitude compression state for a long time.

The working principle is as follows: for small-scale manual vibration rolling, when the device is used, the device is hinged through a handle (not shown in the figure), then a person drags the device to move and roll on a construction site, and when the device is used on a large project, the device can be installed on a vehicle and dragged by the vehicle. No matter the vehicle is dragged or the handle is hinged and manually dragged, the connection angle of the vehicle is automatically selected according to the actual terrain, so that the 'overturning' possibly caused by the problem of the stress angle during dragging is prevented. The caster can be put down according to the requirement when in use, so that the caster can be quickly moved to a working position. The device has multiple working modes which can be selected, one is that pure vibration, namely the driving motor 3 does not work, and the power motor 18 works, so that the rolling part realizes vibration in the vertical direction under frequent impact jacking of the spring and the roller 7 on the rotating shaft 6. Secondly, only rolling, namely, starting the driving motor 3, and rolling the lower rolling body 9 in a rotating way. Thirdly, rolling while vibrating.

Preferably, in order to stabilize the vibration and simplify the structure, the rotating shafts 6 are respectively arranged in the front and the back of the groove, and the torsion bar 5 is arranged at the central position between the two rotating shafts 6.

Further, in order to make the torsion bar 5 prop up from the middle of the housing as much as possible, as shown in fig. 5, a groove penetrating in the left-right direction is provided on the side wall of the cylinder 4, and the groove can allow the torsion bar 5 to pass through and rotate freely, so that the interference of the cylinder 4 can be reduced as much as possible and the torsion bar 5 can be disposed near the center of the housing.

Further, in order to make the vibration more uniform and stable, the grooves are rectangular, and the heavy springs 20 are arranged in a rectangular array.

Further, in order to more simply and effectively realize the detachable connection of the upper connecting part 10 and the lower rolling body 9, as shown in fig. 3, two opposite sides of the edge of the upper connecting part 10 are respectively provided with a slide block 11, the upper part of the lower rolling body 9 is provided with an annular cavity 12 near the edge, the opening of the cavity 12 faces the slide block 11, and the bottom of the cavity 12 opposite to the opening is provided with a limit rib 1201 at each end in a certain diameter direction, so that the slide block 11 is inserted into the cavity 12 and moves circumferentially along the cavity 12 to be in contact with the corresponding rib, the lower rolling body 9 is driven to rotate together, and buffer rubbers can be further arranged on the side surfaces of the two ribs to reduce the collision impact when in contact with the side surfaces of the slide block 11.

Further, the sliding block 11 is a telescopic structure capable of changing a gap between the sliding block 11 and the cavity bottom of the cavity 12, that is, the length of the sliding block 11 can be adjusted, so that the gap between the free end of the sliding block 11 and the cavity bottom of the cavity 12 is changeable, that is, the sliding range of the upper connecting part 10 on the lower rolling body 9 is larger, flexible and adjustable, and adaptable to specific working requirements.

Further, as shown in fig. 4, the top support member 8 is a plate-shaped structure perpendicular to the torsion bar 5, and a U-shaped notch is formed in a side of the top support member connected to the bottom of the groove, so that the top support effect is more effective and stable, the material consumption of the top support member 8 is reduced, and the structure is stronger.

Further, due to the arrangement of the power motors 18, especially when a plurality of power motors 18 are arranged, the left and right weight of the whole rolling device is seriously unbalanced, and in order to balance the weight, as shown in fig. 1, a balance weight disc 21 for balancing the power motors 18 is further arranged on the outer wall of the machine shell 1 on the side where the cylindrical 4 gear is located.

Further, as shown in fig. 1 and 3, the upper surface of the upper connecting portion 10 has an annular sliding groove 1001 near the edge thereof, the torsion bar 5 and the rotating shaft 6 are located in the same plane, and the top stay 8 hangs down and extends into the sliding groove 1001 in the non-operating state. This configuration allows the torsion bar 5 and the shaft 6 to be designed in the same plane, and the recess may have a smaller design size (otherwise, the torsion bar 5 must be installed upward to reserve sufficient size for accommodating the top support 8 below, so that the design will increase the size of the recess, making the structure larger and less compact, and reducing the reliability under the vibration condition).
