The length of the movable plate 6051 may be determined according to the volume of the vehicle compartment 70.

For example, when the volume of the carriage 70 is small, the material in one third of the carriage 70 can be pushed out by the movable plate 6051 when the movable plate 6051 is turned over, and the length of the movable plate 6051 is set to occupy one third of the height of the carriage 70. When the volume of the compartment 70 is large, it is necessary to push out half of the material in the compartment 70 in advance, and the length of the movable plate 6051 is set to occupy half of the height of the compartment 70.

Specifically, the semitrailer is used to transport the material to the discharge location for discharge. When the pre-unloading is performed to reduce the amount of material accumulation in the carriage 70, the driving mechanism 102 is operated by connecting the control switch with the power supply, and the driving mechanism 102 drives the transmission mechanism 103 to rotate clockwise. The transmission mechanism 103 is screwed with the slide mechanism 301 during rotation, and the slide mechanism 301 is movable on the ceiling wall of the vehicle compartment 70. The sliding mechanism 301 can drive the pressing mechanism 302 to move during moving, and the lifting mechanism 603 moves downward when the pressing mechanism 302 passes through the discharging assembly 60. And the plurality of pushing mechanisms 302 are driven by the plurality of discharging frames 304 to sequentially pass through the lifting mechanism 603, so that the lifting mechanism 603 is driven in a reciprocating manner, and materials pushed to the front in the rear can be discharged from the carriage 70 again. The lifting mechanism 603 moves downwards to drive the movable plate 6051 to synchronously overturn downwards, so that the movable plate 6051 can push the material on the upper layer in the carriage 70 to push out of the carriage 70 in the overturning process, and in order to avoid that the material can not be pushed out of the carriage 70 when the movable plate 6051 positioned behind the carriage 70 overturns, the sliding mechanism 301 can be driven to reciprocate on the carriage 70 according to the volume of the carriage 70, namely, the sliding mechanism 301 can reciprocate twice, three times or four times by controlling the operation time of the driving mechanism 102, and the material pushed forward in the rear can be discharged. Thereby reducing the amount of material accumulation in the compartment 70 and reducing the resistance to subsequent pushing.

When the driving discharging assembly 30 and the driven discharging assembly 40 are mutually fixed, the transmission mechanism 103 is driven to rotate clockwise, so that the driving discharging assembly 30 moves close to the driven discharging assembly 40 and continuously moves, the clamping mechanism 303 is inserted into the outer shell 4011, the positioning mechanism 4014 can be opened by the clamping mechanism 303, and then the positioning mechanism 4014 is reset and can be in limiting fixed connection with the clamping mechanism 303.

When the rest materials in the carriage 70 are pushed out of the carriage 70, the driving mechanism 102 is operated to drive the transmission mechanism 103 to rotate anticlockwise, at this time, the sliding mechanism 301 drives the outer shell 4011 to move synchronously, then the fixing frame 407 and the supporting columns 403 drive the pushing plate 405 and the ejection piece 408 to move, and the pushing plate 405 and the ejection piece 408 jack up the blocking piece 406 in the moving process and cooperate with the pushing plate 405 to push the materials forward, so that the materials are pushed out of the carriage 70 to be discharged.

In one embodiment of the present application, as shown in fig. 1, the above-mentioned semitrailer box unloading device may further include an auxiliary driving mechanism 50, where the auxiliary driving mechanism 50 is disposed on the vehicle box 70, and an output end of the auxiliary driving mechanism 50 is connected to the connecting frame 404.

It should be noted that, the auxiliary driving mechanism 50 may be a hydraulic telescopic rod, and the hydraulic telescopic rod is connected to the connecting frame 404, and is connected to the power supply through a control switch to operate, so as to push the connecting frame 404 to reciprocate.

Specifically, when the material in the carriage 70 is discharged, the auxiliary driving mechanism 50 can be started at the same time, so that the pushing force can be applied to the moving pushing plate 405, the discharging is more convenient, and after the discharging is completed, the pushing plate 405 can be driven to reset.

To sum up, the semitrailer railway carriage or compartment discharge apparatus of this application, through the cooperation of drive assembly and initiative subassembly of unloading, the partial material of discharging earlier reduces the material accumulation volume of railway carriage or compartment inside to resistance when reducing unloading can also increase the inside movable space of railway carriage or compartment simultaneously, effectively avoids the material to pile up the space inadequately problem that the too high leads to. And the material is pushed out of the carriage through the matching of the driving unloading assembly and the driven unloading assembly, so that the unloading process is smoother, and the unloading efficiency is further improved.

While embodiments of the present application have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the present application, and that variations, modifications, alternatives, and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the present application.
