[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 An underground ore transport vehicle comprises a bucket 1, a pushing assembly 2 for pushing the bucket 1 is installed at the lower side of the bucket 1, the pushing assembly 2 comprises a sleeve rod 201 and a push rod 202 installed inside the sleeve rod 201, and an end of the push rod 202 is pressed against the ground;

[0034] A driving assembly 3 is installed inside the truck 1 to make the push rod 202 extend from the inside of the sleeve rod 201. The driving assembly 3 includes an extrusion plate 301. A bellows 302 is fixedly installed between the lower end of the extrusion plate 301 and the lower inner wall of the truck 1. The inside of the bellows 302 is connected with the inside of the sleeve rod 201. When the bellows 302 contracts, the internal air can enter the inside of the sleeve rod 201.

[0035] The push assembly 2 also includes a fixed seat 203 rotatably connected to the sleeve rod 201, and a ventilation groove 204 is provided inside the fixed seat 203. The two ends of the ventilation groove 204 are respectively connected to the inside of the bellows 302 and the inside of the sleeve rod 201. The air in the bellows 302 enters the sleeve rod 201 through the ventilation groove 204.

[0036] A moving seat 104 that moves on the rails is installed at the lower end of the truck bed 1, and a door panel 105 is installed at the lower end of the truck bed 1 close to the extrusion plate 301. The goods can be unloaded after the door panel 105 is opened.

[0037] By adopting the above technical scheme, when the staff puts the coal into the bucket 1, the coal can squeeze the squeezing plate 301 under the action of gravity to make it drop. After the squeezing plate 301 drops, it can squeeze the bellows 302 at its lower end, so that the bellows 302 contracts. After the bellows 302 contracts, it can squeeze the air inside it, and the squeezed air can enter the ventilation groove 204, and enter the sleeve rod 201 through the ventilation groove 204 for compression. When the staff needs to push the mine car to transport the coal, the push rod 202 is put in a movable state. At this time, the compressed air can push the push rod 202 to slide outward in the sleeve rod 201, and after the end of the push rod 202 squeezes the ground, it can push the bucket 1 and the moving seat 104 to move under the action of the reaction force of the air. The push rod 202 can play a role of assisting when pushing the moving seat 104 to move, so that the staff can be easier when starting to push the mine car.

[0038] like Figure 2 - Figure 3As shown, a fixing block 304 is fixedly installed at one end of the extrusion plate 301, and the outer wall of the fixing block 304 is in contact with the inner wall of the bucket 1, and a movable groove 305 is provided at one end of the fixing block 304 in contact with the inner wall of the bucket 1, and a clamping block 306 is slidably installed inside the movable groove 305, and a clamping groove 101 adapted to the clamping block 306 is provided at a position corresponding to the clamping block 306 on the lower side of the inner wall of the bucket 1, and when the clamping block 306 is located inside the clamping groove 101, the fixing block 304 and the extrusion plate 301 are fixed;

[0039] The upper and lower sides of the end of the clamping block 306 close to the clamping slot 101 are inclined, and the end of the clamping block 306 close to the inside of the movable slot 305 is elastically connected to the inner wall of the movable slot 305 through the extrusion spring 307;

[0040] A support spring 303 for supporting the extrusion plate 301 is installed at the lower end of the extrusion plate 301. The lower end of the support spring 303 is fixedly installed on the inner wall of the bucket 1. The support spring 303 can squeeze the extrusion plate 301 to make it rise.

[0041] By adopting the above technical solution, when the extrusion plate 301 drops to the lowest end, the block 306 can move inside the movable groove 305 under the action of the extrusion spring 307 and extend from the movable groove 305. The extended block 306 can be inserted into the slot 101 to fix the fixed block 304. After the fixed block 304 is fixed, the extrusion plate 301 fixedly connected thereto can also be fixed. After the extrusion plate 301 is fixed, the air can maintain sufficient thrust when pushing the push rod 202, thereby making the thrust greater, thereby avoiding the extrusion plate 301 from moving under the reaction force of the air, resulting in insufficient thrust on the bucket 1.

[0042] like Figure 2 , Figure 4 As shown, a pull rope 205 is fixedly installed at one end of the push rod 202 close to the block 306, and the other end of the pull rope 205 passes through the sleeve rod 201, the truck bucket 1, the fixed block 304 in sequence and is fixedly connected to the block 306. After the push rod 202 extends a certain length from the sleeve rod 201, the block 306 is pulled to move by the pull rope 205.

[0043] By adopting the above technical solution, when the push rod 202 extends a certain distance from the inside of the sleeve rod 201, the pull rope 205 can be in a taut state. When the push rod 202 continues to move, the pull rope 205 can pull the block 306 to move, so that the block 306 is separated from the slot 101. After the block 306 is separated from the slot 101, the support spring 303 can lift the extrusion plate 301 under its own toughness. When the extrusion plate 301 is lifted, the corrugated tube can be pulled 302 causes it to deform, thereby allowing the bellows 302 to return to its initial state. During the recovery process of the bellows 302, the air in the sleeve rod 201 can be sucked back into the bellows 302 through the ventilation groove 204. At this time, after the pressure changes, the push rod 202 can move toward the inside of the sleeve rod 201, thereby being retracted into the sleeve rod 201. When the coal is placed into the extrusion plate 301 next time, the air can be compressed between the bellows 302 and the push rod 202 again.

[0044] like Figure 4 , Figure 5 As shown, a movable groove 206 is provided on the upper side of the push rod 202, and an insert block 207 for fixing the push rod 202 is slidably installed inside the movable groove 206. One end of the insert block 207 close to the movable groove 206 is elastically connected to the inner wall of the movable groove 206 through a return spring 208. A slot 209 adapted to the insert block 207 is provided at a position corresponding to the inner wall of the sleeve rod 201 and the insert block 207. After the insert block 207 is plugged into the slot 209, the push rod 202 and the sleeve rod 201 are fixed. A push rod 210 for squeezing the insert block 207 is penetrated and slidably provided at the corresponding position of the sleeve rod 201 and the insert block 207.

[0045] By adopting the above technical solution, when the staff needs to make the push rod 202 in a movable state, the staff pushes the push rod 210, so that the push rod 210 moves relative to the sleeve rod 201. After the push rod 210 moves, it can push the plug block 207 to move. After the plug block 207 moves, it can disengage from the slot 209 and shrink into the movable groove 206. At this time, the push rod 202 is in a state that can move relative to the sleeve rod 201. When the staff does not push the push rod 210 and the position of the plug block 207 corresponds to the position of the slot 209, the return spring 208 can squeeze the plug block 207, so that the plug block 207 extends out from the movable groove 206. The extended plug block 207 can be inserted into the slot 209. After the plug block 207 is inserted into the slot 209, the push rod 202 can be fixed inside the sleeve rod 201. At this time, when the push rod 202 moves relative to the sleeve rod 201, it can maintain sufficient driving force to push the bucket 1 and the movable seat 104 to move.

[0046] like Figure 7 , Figure 8As shown, a push plate 4 for pushing out the residual coal is slidably installed on the upper end of the extrusion plate 301, and the lower end of the push plate 4 is in contact with the upper end of the extrusion plate 301, and the upper end of the extrusion plate 301 is in an inclined structure;

[0047] Both ends of the push plate 4 are rotatably connected to the column wheel 401, and a guide groove 102 for limiting the column wheel 401 is opened at the position of the inner wall of the truck bucket 1 corresponding to the column wheel 401, and the guide groove 102 has a triangular structure, and a transition groove 103 is opened at the position where the lower side of the vertical part of the guide groove 102 is connected to the inclined part. The transition groove 103 is inclined, and the lowest point of the transition groove 103 is located on the lower side of the inclined part of the guide groove 102.

[0048] By adopting the above technical solution, when the extrusion plate 301 is squeezed by the gravity of the coal mine and descends, it can drive the upper push plate 4 to descend. During the descending process of the push plate 4, the column wheel 401 can also descend, and the column wheel 401 will descend along the vertical part of the guide groove 102. When the column wheel 401 descends to a certain position, it can enter the transition groove 103. When the extrusion plate 301 is at the lowest end, the column wheel 401 is located at the lowest end of the transition groove 103. Then, when the extrusion plate 301 rises, due to the lowest end of the transition groove 103, the column wheel 401 The end is located at the lower side of the inclined part of the guide groove 102, so after the column wheel 401 rises, it can enter the lower inclined part of the guide groove 102, and then move along the inclined part. When the column wheel 401 moves, it can drive the push plate 4 to move. Since the push plate 4 is slidingly connected to the extrusion plate 301, and the lower end of the push plate 4 is in contact with the upper end of the extrusion plate 301, the moving direction of the push plate 4 will be restricted, and after the push plate 4 moves, the coal stuck to the upper end of the extrusion plate 301 can be pushed down, thereby making the coal unloading cleaner.

[0049] Instructions for use: When the device is in use, after the coal is put into the bucket 1, the coal can squeeze the squeezing plate 301 to make it drop, and the squeezing plate 301 can squeeze the air in the bellows 302. After that, the staff pushes the push rod 210, so that the push rod 210 squeezes the plug block 207, and the plug block 207 is pushed out from the slot 209. After the plug block 207 is separated from the slot 209 and retracted into the movable groove 206, the push rod 202 can be extended from the sleeve rod 201 under the action of air pressure, and the rear end of the push rod 202 can squeeze the ground. At this time, the sleeve rod 201 can be pushed under the reaction force of the air, so that the bucket 1 and the movable seat 104 move. At this time, the pushing energy of the staff can be The movable seat 104 and the bucket 1 can be easily moved. When they are moved to the designated unloading position, the door panel 105 can be opened to unload the materials in the bucket 1. After the push rod 202 moves a certain distance relative to the sleeve rod 201, the pull rope 205 can be pulled to disengage the block 306 from the slot 101. After the coal is unloaded from the bucket 1, the extrusion plate 301 can rise under the action of the support spring 303. After the extrusion plate 301 rises, it can be reset to its initial position. Moreover, during the rising process of the extrusion plate 301, the column wheel 401 can move along the inclined part of the guide groove 102. When the column wheel 401 moves, it can drive the push plate 4 to move. After the push plate 4 moves, the coal stuck on the extrusion plate 301 can be pushed out from the extrusion plate 301.

[0050] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
