[0030] The bottom surface of the carriage 1 is provided with a rectangular bottom plate 101, the length direction of the bottom plate 101 is arranged along the movement direction of the transport vehicle, so that the size of the carriage 1 can better adapt to the narrow and long working space of the underground mine, the front end of the bottom plate 101 is fixedly installed with a front wall 103, the front wall 103 is arranged in parallel with the width direction of the bottom plate 101, and the two ends of the front wall 103 are respectively fixedly installed with a side wall 102, the two side walls 102 are symmetrical and arranged perpendicularly to the front wall 103, the rear end of the carriage 1 is an open discharge port for discharging materials after the materials are transported to the designated location, and a rear door 2 is arranged at the discharge port, the rear door 2 is adapted to the shape of the discharge port, and the opening and closing of the discharge port are realized by the opening and closing of the rear door 2, so as to form a semi-closed space which can be opened, and is used for carrying materials and cooperating with the vehicle frame to complete material transportation and unloading.

[0031] A pushing plate 4 is slidably installed at a position close to the front end inside the carriage 1, and is used for pushing the materials in the carriage 1 to the discharge port and discharging out, the rear end of the bottom plate 101 is bent downward and forms a certain angle with the horizontal plane, so that not only the volume of the carriage 1 is increased to be able to transport more materials, but also the cross-sectional area of the discharge port is increased, which is beneficial to improve the discharging speed.

[0032] The pushing plate 4 comprises a horizontal pushing plate 401, the horizontal pushing plate 401 is arranged in parallel with the rear door 2 and is adapted to the cross section of the carriage 1, and the two ends of the horizontal pushing plate 401 are fixedly installed with a side pushing plate 402 close to the position of the side wall 102, the side pushing plate 402 extends to the rear end of the carriage 1 along the side wall 102, and the pushing plate 4 is in C shape as seen from the top of the carriage 1, and forms a semi-enclosed structure for the materials in the carriage 1, which can more efficiently push the materials to move to the rear end of the carriage 1.

[0033] The side pushing plate 402 is a box-shaped structure with one side opening, the opening of the side pushing plate 402 faces the side wall 102, the side pushing plates 402 on the two sides are in contact with the corresponding side wall 102 to form a cavity, and a pushing driving device 5 is arranged in the cavity to drive the side pushing plate 402 to move in the carriage 1.

[0034] In the embodiment, the pushing driving device 5 is a servo hydraulic cylinder, the fixed end of the servo hydraulic cylinder is fixedly installed on the side pushing plate 402, and the telescopic end is fixedly installed on the front wall 103, the telescopic end of the servo hydraulic cylinder is extended or retracted to drive the pushing plate 4 to move forward and backward in the carriage 1, push the materials in the carriage 1 to the discharge port to be discharged, and return after the discharging is completed.

[0035] In addition to the embodiment, the pushing driving device 5 can also be selected from one of a servo air cylinder and a servo electric cylinder, and the telescopic movement of the telescopic end of the pushing driving device 5 drives the pushing plate 4 to move forward and backward in the carriage 1.

[0036] The rear end of the compartment 1 is provided with a rear cross beam 3, the two ends of the rear cross beam 3 are fixedly connected with two side wall panels 102 respectively, the upper end of the tail door 2 is hingedly installed on the rear cross beam 3, the lower end abuts against the rear end of the side wall panels 102 and the bottom plate 101, and the rear side of the tail door 2 is provided with an opening driving device 6 for driving the opening and closing of the tail door 2, so as to realize the transportation and unloading of the materials in the compartment 1.

[0038] In the embodiment, the opening driving device 6 can also be one of a servo pneumatic cylinder or a servo electric cylinder, and the opening and closing of the tail door 2 are driven through the telescopic movement of the telescopic end.

[0039] Initially, the tail door 2 is in a closed state, in order to prevent the deformation and damage of the tail door 2 caused by the accumulation of materials at the tail door 2, the compartment of the underground flat-pushing unloading vehicle also has a control device for controlling the sequential actions of the opening driving device 6 and the material pushing driving device 5.

[0040] When the transportation vehicle transports the materials to the designated place, the control device first controls the telescopic end of the opening driving device 6 to extend, drives the tail door 2 to open, after the tail door 2 is opened, the control device controls the telescopic end of the material pushing driving device 5 to extend, drives the material pushing plate 4 to move to the rear end of the compartment 1, and pushes the materials in the compartment 1 to be unloaded.

[0041] Due to the downward bending of the rear end of the bottom plate 101, at the moment when the tail door 2 is opened, the materials located at the slope at the rear end of the compartment 1 are unloaded under the action of gravity, so that a part of the materials can be unloaded during the time waiting for the tail door 2 to be completely opened, and the material pushing plate 4 only needs to be moved to the position aligned with the starting position of the bending of the bottom plate 101, so as to ensure that all the materials are unloaded, the moving stroke of the material pushing driving device 5 is shortened, compared with the prior art, the unloading time is saved, the work efficiency is improved, and the use of the material pushing driving device 5 with a shorter moving stroke is also conducive to reducing the cost.

[0042] After all the materials are unloaded, the telescopic end of the material pushing driving device 5 is retracted, the material pushing plate 4 is driven to reset, then the opening driving device 6 acts, and the tail door 2 is closed.

[0043] When the pushing plate 4 is reset, if there is residual material in the gap between the pushing plate 4 and the front wall 103, the pushing plate 4 cannot be reset to the initial position, and even worse, the pushing plate 4 can be stuck and the pushing driving device 5 can be damaged. In order to improve the reliability, the side wall 102 is provided with a material falling hole 9 at the bottom close to the front end of the carriage 1. The pushing plate 4 drives the residual material to fall out of the carriage 1 through the material falling hole 9, so that the labor intensity of the workers is reduced.

[0044] As shown in Figure 6 The top end of the side wall 102 is provided with a sliding groove 7 in the front-rear direction of the carriage 1. The sliding groove 7 has a C-shaped cross section, and the opening faces the inside of the carriage 1. The side pushing plate 402 is detachably fixed with a sliding block 8 at the position corresponding to the sliding groove 7. The sliding block 8 is slidingly installed in the sliding groove 7, so that the pushing plate 4 always moves in the front-rear direction of the carriage 1.

[0045] In the embodiment, the material of the sliding block 8 can be wear-resistant steel or other existing wear-resistant materials. The sliding block 8 slides in the sliding groove 7, so that the moving direction of the pushing plate 4 is not deviated.

[0046] In order to make the sliding of the sliding block 8 in the sliding groove 7 more smooth, the oil injection hole can be provided on the sliding groove 7 and the lubricating grease can be injected, or the roller can be added to the sliding block 8. The above are the structures widely used in the prior art and are well known to those skilled in the art, and will not be described here.

[0047] For those skilled in the art, according to the teaching of the present application, the changes, modifications, replacements and variations of the embodiments without departing from the principles and spirits of the present application still fall within the protection scope of the present application.
