[0030] The above-mentioned coal mining and transportation equipment is provided with a support base 2 as a supporting carrier of the transport vehicle 1, and an expansion folding plate 301 is provided, which can be folded and unfolded, so as to increase the internal space of the transport vehicle, and a micro motor 305 can be provided to drive the double-headed threaded rod 303 to rotate, and the connecting block 302 is driven by the double-headed threaded rod 303 to move on its outside and pull the expansion folding plate 301, so that the expansion folding plate 301 is stretched and unfolded, so as to achieve the purpose of automatic unfolding; at the same time, the expansion folding plate 301 will also drive multiple sliders 307 to slide together on the outside of the slide rod 306 during the stretching process, which plays a guiding role in the unfolding of the expansion folding plate 301, so that the expansion folding plate 301 can unfold more smoothly, and when the folding surface of the expansion folding plate 301 is unfolded, more coal materials can be stored, thereby reducing the number of transportation times.

[0031] The expansion folding plate 301 is located inside the transport vehicle 1 , and the expansion folding plate 301 is made of plastic. The connecting block 302 and the sliding block 307 are fixedly connected to both ends of the outer side of the expansion folding plate 301 .

[0032] By setting the expansion folding plate 301 inside the transport vehicle 1, the length of the transport vehicle 1 can be increased after being unfolded. At the same time, the other ends of the connecting block 302 and the slider 307 are fixedly connected to the two ends of the outer side of the expansion folding plate 301. When the expansion component 3 is unfolded, it can be pulled apart from the two ends of the expansion folding plate 301, making its unfolding smoother.

[0033] Furthermore, the lifting component 4 includes a concave groove 401 arranged on the lower surface of the support base 2, and a double-headed motor 402 is arranged inside the concave groove 401. The driving end of the double-headed motor 402 is fixedly provided with a transmission rod 403, one end of the transmission rod 403 is fixedly provided with a main bevel gear 404, one side of the main bevel gear 404 is meshed with a secondary bevel gear 405, one end of the secondary bevel gear 405 is fixedly provided with a screw rod 406, the outer side thread of the screw rod 406 is provided with a moving block 407, the top hinge of the moving block 407 is provided with a first support rod 408, the other end hinge of the first support rod 408 is provided with a hinge block 409, and the hinge blocks 409 are symmetrically arranged at both ends of the bottom of the transport vehicle 1.

[0034] By setting up a double-headed motor 402, two transmission rods 403 can be driven to rotate, and the two transmission rods 403 respectively drive the main bevel gear 404 to engage with the auxiliary bevel gear 405. By setting up a screw rod 406, the movable block 407 is driven by the auxiliary bevel gear 405 to move horizontally in the concave groove 401, and the first support rod 408 is driven to change from an inclined state to a vertical state during the movement, thereby lifting one end component of the transport vehicle 1, making the transport vehicle 1 inclined, so that the coal material is discharged from the inclined end of the transport vehicle 1, which is convenient for pouring out the internal coal material, effectively reducing the difficulty of unloading for workers and facilitating improving work efficiency.

[0035] In addition, a second support rod 410 is symmetrically arranged at the bottom of the transport vehicle 1 , and a hinge 5 is arranged at the bottom of the second support rod 410 , and the hinge 5 is fixedly connected to the support base 2 .

[0036] By providing the hinge 5 and the second support rod 410, the lifting assembly 4 can drive the second support rod 410 to tilt at an angle inside the hinge 5 during the process of lifting the transport vehicle 1, thereby achieving the purpose of limiting.

[0037] A push rod 6 is fixedly arranged at one end of the transport vehicle 1, and wheels 7 are arranged at the four corners of the support base 2. The push rod 6 can drive the wheels 7 to push the transport vehicle 1, so that the transport vehicle 1 can be moved.

[0039] The working principle of the above-mentioned coal mining and transportation equipment is as follows:

[0040] When there is a large amount of coal material to be transported, the micro motor 305 can be turned on to drive the double-headed threaded rod 303 to rotate, and the connecting block 302 is driven by the double-headed threaded rod 303 to move on its outside. During the movement of the connecting block 302, the expansion folding plate 301 will be pulled to stretch and unfold the expansion folding plate 301. At the same time, during the stretching process, the expansion folding plate 301 will also drive multiple sliders 307 to slide together on the outside of the slide rod 306, which plays a guiding role in the unfolding of the expansion folding plate 301, making the expansion folding plate 301 unfold more smoothly. When the folding surface of the expansion folding plate 301 is unfolded, the internal space of the transport vehicle 1 can be effectively increased to store more coal materials and reduce the number of transportation times.

[0041] When unloading, the double-headed motor 402 can be turned on, so that the double-headed motor 402 drives the transmission rod 403 to rotate, and the two transmission rods 403 respectively drive the main bevel gear 404 to mesh with the sub-bevel gear 405, and the sub-bevel gear 405 drives the screw rod 406 to rotate under the meshing transmission. During the rotation of the screw rod 406, the moving block 407 is moved in the concave groove 401 under the drive of the thread, and the first support rod 408 is moved during the movement to lift one end component of the transport vehicle 1, so that the transport vehicle 1 is tilted, so that the coal material is discharged from the tilted end of the transport vehicle 1, which is convenient for pouring out the internal coal material, effectively reducing the difficulty of unloading for workers and facilitating improving work efficiency.
