an outer shaft 36 coaxially and movably sleeved outside the inner shaft 34 in a horizontal state, one end of the outer shaft is fixedly inserted into one end of the other wheel shaft 11, and the inner wall of the outer shaft is provided with a limit strip 37 extending along the axial direction of the inner shaft;

wherein, both ends of the outer shaft 36 are provided with shaft seats 38, and the shaft seats 38 are fixedly connected with the outer wall of the first hollow beam 29.

The outer shaft 36 and the inner shaft 34 are matched with the limiting groove 35 through the limiting strip 37, so that the outer shaft 36 can drive the inner shaft 34 to synchronously rotate when rotating, and the inner shaft 34 and the outer shaft 36 are respectively connected with the belt pulleys 9 of the two conveyor belt assemblies 2, so that the rotation synchronism of the belt pulleys 9 of the two conveyor belt assemblies 2 is ensured. The shaft seats 38 are arranged at the two ends of the outer shaft 36, so that the friction resistance in the rotating process of the outer shaft 36 is reduced, and the smooth rotation of the telescopic driving shaft 5 is ensured.

The drive mechanism 6 includes:

a second stepping motor 39 fixedly disposed on a side wall of the first hollow beam 29 in a horizontal state;

two synchronizing wheels 40 are fixedly sleeved on the outer shaft 36 and the output shaft of the second stepping motor 39 respectively;

the synchronous belt 41 is sleeved outside the two synchronous wheels 40 and used for driving the two synchronous wheels 40 to rotate synchronously.

A caster 42 for sliding on the frame body 1 is fixedly connected to the outer side of the end of each conveyor belt assembly 2. Both ends of every conveyer belt subassembly 2 all support at the top of frame body 1 through truckle 42 to avoid the one end of conveyer belt subassembly 2 to take place the condition of sinking, on the other hand, at two sets of conveyer belt subassemblies 2 carry out the in-process that the interval was adjusted, the both ends of every conveyer belt subassembly 2 all reduce through truckle 42 and the frame body 1 between the frictional resistance.

Through the rotation of second synchronous motor, cooperation hold-in range 41 drives two synchronizing wheels 40 and carries out synchronous revolution, and then drives outer axle 36 through the rotation of synchronizing wheel 40 and rotatory, and then drives interior axle 34 through the rotation of outer axle 36 and together rotate to make two hold-in range 41 subassemblies carry out synchronous conveying.

The foregoing has described the general principles, principal features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
