[0030] The rotating air guide sleeve ring 9 is fixedly connected with the paver material collecting base 1, the rotating air guide sleeve ring 9 is communicated with the inflation pump 11 through a pipe, the spiral inflation material collecting rod 3 and the rotating air guide sleeve ring 9 are sealed through the labyrinth sealing method, the spiral inflation material collecting rod 3 and the blockage prevention limiting rod 5 are sealed through the labyrinth sealing method, the side end of the hopper 2 is fixedly installed with an infrared range finder 12, and the end of the blockage prevention piston rod 6 is rotatably installed with a roller 13.

[0031] The paver material collecting base 1 is a basic support structure of the whole device, installs other components and provides a stable working platform, and simultaneously serves as a main channel for collecting materials;

[0032] The hopper 2 is used for receiving the un-inflated material poured by a transport vehicle and plays a role of feeding material;

[0033] The spiral inflation material collecting rod 3 realizes material collecting through rotation, transports the material in the hopper 2 to a paving device, and simultaneously internally inflates to perform inflation operation on the material;

[0034] The inflation hole 4 sprays gas from the inside of the spiral inflation material collecting rod 3 to inflate the material;

[0035] The blockage prevention limiting rod 5 can still maintain sealing when relative rotation with 30 is maintained, provides fixed limitation for the cam 8, and ensures that the cam 8 can accurately act in a specific position;

[0036] The blockage prevention piston rod 6 blocks the inflation hole 4 when the cam 8 acts on the top to prevent the material from entering, and opens the inflation hole 4 to spray gas for inflation when the cam 8 acts on the bottom;

[0042] Roller 13: reduce the friction when the anti-blocking piston rod 6 contacts the cam 8, make the action more smooth.

[0043] Working principle:

[0044] Firstly, during installation, the spiral inflation material collection rod 3 is connected with the power mechanism of the paver through gears and the like, and the infrared distance meter 12 is connected with the control system of the vehicle, in use, the transport vehicle directly pours the un-inflated material into the hopper 2, after the transport vehicle is emptied, the infrared distance meter 12 detects that the transport vehicle leaves, and then the power mechanism drives the spiral inflation material collection rod 3 to rotate counterclockwise, the spiral inflation material collection rod 3 collects the material in the hopper 2 and sends it to the paver.

[0045] Secondly, during the material collection, the inflation pump 11 starts to send the gas into the rotating gas guide sleeve ring 9, and then the gas is sent into the spiral inflation material collection rod 3 by the rotating gas guide sleeve ring 9, the spiral inflation material collection rod 3 rotates during the rotation of the material feeding, which drives the inflation hole 4 and the internal components to rotate, since the anti-blocking limit rod 5 is fixedly connected with the paver material collection base 1, the cam 8 remains stationary when the spiral inflation material collection rod 3 rotates, when the anti-blocking piston rod 6 is located above, it is extruded by the cam 8 and slides upward against the elastic force of the spring 7 to block the inflation hole 4, which can prevent the material above from falling into the inflation hole 4, when the anti-blocking piston rod 6 rotates to the lower side, the anti-blocking piston rod 6 loses the constraint of the anti-blocking limit rod 5 and slides upward under the elastic force of the spring 7, thereby opening the inflation hole 4, so that the gas in the spiral inflation material collection rod 3 can be sprayed out along the inflation hole 4, thereby performing the inflation operation on the material in the paver material collection base 1.

[0046] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the present application, and are not a limitation on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description.
