[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example: Reference Figure 1 and Figure 2 The shown embodiment shows a transport vehicle for a complete discharge of materials in a mine, comprising a transport trolley 2, a mobile frame 1 and a support column 3. The bottom of the front end of the transport trolley 2 for material discharge is rotatably arranged on the mobile frame 1 via a rotating shaft 5. A drive cylinder 4 is rotatably arranged on the mobile frame 1, and the output end of the drive cylinder 4 is movably connected to the bottom of the transport trolley 2. An opening and closing unit is also included. When the transport trolley 2 is tilted to discharge materials, the obstruction of the front baffle 6 of the transport trolley 2 to the ore material can be automatically released to facilitate the complete discharge of the material. After the transport trolley 2 returns to its original position, the front baffle 6 automatically returns to its original position.

[0019] When dumping, the front baffle 6 is automatically moved to remove the obstruction to the ore material to facilitate the complete discharge of the material. After the transport trolley 2 returns to its original position, the front baffle 6 automatically returns to its original position to block the material discharge opening.

[0020] As a preferred implementation in this embodiment, Figure 1-3 and Figure 5 As shown, the opening and closing unit includes two mounting frames 7 with drive chains 8 disposed therein and toothed transmission members disposed at both ends of the rotating shaft 5; The driving chain 8 is arranged in an L shape through a guide gear 9, a driving shaft 12 is rotatably arranged on the mounting frame 7, and a driving gear 11 and a driven gear 13 are respectively installed at both ends of the driving shaft 12, and the driving gear 11 is gear-engaged with the driving chain 8; The front baffle 6 is movably arranged at the front unloading opening of the transport trolley 2, and the front baffle 6 includes a plurality of baffles, and both ends of the plurality of baffles 6 are connected to the driving chains 8 on both sides through connecting columns 10; The driven gear 13 is gear-engaged with the gear transmission member.

[0021] When in use, the transport trolley 2 can be driven by the driving cylinder 4 to rotate around the rotating shaft 5. When the transport trolley 2 rotates, its rotating shaft will drive the toothed transmission members at both ends to rotate. Since the toothed transmission members are toothed with the corresponding driven gear 13, the driven gear 13 can finally make the driving gear 11 drive the driving chain 8 to move, so that multiple baffles move upward, so that the unloading opening at the front end of the transport trolley 2 is opened, and the ore material can be discharged from this unloading opening. During unloading, the front end of the bottom plate of the transport trolley 2 and the lower end of the inclined front baffle 6 are gradually separated and form a larger and larger unloading opening, so that the material can fall from this unloading opening, which can effectively prevent some ore materials from accumulating at the junction of the front end of the bottom plate and the lower end of the inclined front baffle 6, making the unloading more thorough. After the unloading is completed, the driving cylinder 4 drives the transport trolley 2 to rotate in the opposite direction and return to its original position. In this process, the toothed transmission member drives the driven gear 13 to rotate in the opposite direction and finally restores the multiple baffles to their original positions.

[0022] It should be noted that: 1. Multiple baffles constitute the inclined front baffle 6, and the gaps between the multiple baffles are very small; 2. A protective cover can be set to seal the driven gear 13 and the toothed transmission member to prevent the ore or soil from causing the gears to get stuck; 3. The driving force of the drive chain 8 when it is running comes from the drive cylinder 4, avoiding the increase of the power source, and also facilitating the coordinated operation of the various components; 4. The toothed transmission member can be a gear.

[0023] As a preferred implementation in this embodiment, Figure 3 As shown, the gear transmission member includes a first large gear 14, a first small gear 16, two sets of second small gears 17 and a second large gear 18; The first pinion 16, two groups of the second pinion 17 and the second large gear 18 are all mounted on a mounting plate 15, the mounting plate 15 is mounted on the mobile chassis 1, a rotating rod is rotatably provided on the mounting plate 17, the first pinion 16 and a group of the second pinion 17 are all mounted on the rotating rod, the first pinion 16 is toothed with the first large gear 14, the two groups of the second pinion 17 are toothed with each other, one group of the second pinion 17 is toothed with the second large gear 18, and the second large gear 18 is toothed with the driven gear 13; The diameter of the first large gear 14 is larger than the diameter of the second large gear 18, the diameters of the first small gear 16 and the two sets of the second small gears 17 are smaller than the second large gear 18, and the diameters of the driven gear 13 and the second large gear 18 are consistent; The axes of the first large gear 14 , the second large gear 18 , and the rotating shaft 5 are all on the same horizontal line.

[0024] When the rotating shaft 5 rotates, the first large gear 14 rotates, and drives the driven gear 13 to rotate through the cooperation of the first small gear 16, the second small gear 17 and the second large gear 18, and finally drives the driving chain 8 to run through the driven gear 13; The diameter of the first large gear 14 is larger than the diameter of the second large gear 18, the diameters of the first small gear 16 and the two groups of the second small gears 17 are smaller than the second large gear 18, and the driven gear 13 has the same diameter as the second large gear 18. The purpose is to accelerate the running speed of the drive chain 8, that is, to use the large gear to drive the small gear to rotate, thereby speeding up the operation of the drive chain 8, and then the unloading opening is quickly opened, which is conducive to the rapid discharge of materials inside the transport cart 2.

[0025] It should be noted that the axes of the first large gear 14, the second large gear 18 and the rotating shaft 5 are all on the same horizontal straight line, so that when the transport trolley 2 rotates around the rotating shaft 5, the driven gear 13 thereon always moves in a circular motion around the axis of the second large gear 18, so that the driven gear 13 and the second large gear 18 always maintain a toothed state.

[0026] As a preferred implementation manner in this embodiment, a start-stop unit is further included to control the start and stop of the movement of the baffle 6.

[0027] A start-stop unit is set. When the front baffle 6 completely removes the blocking of the material discharge opening, the drive chain 8 stops running. At this time, the drive cylinder 4 continues to push the transport trolley 2 to rotate. The bearing capacity of the drive cylinder 4 is small. Compared with the case where the start-stop unit is not set, the drive cylinder 4 also drives the drive chain 8 to move while pushing the transport trolley 2 to rotate. The bearing capacity of the drive cylinder 4 is large. It can be seen that when the start-stop unit is set, the load of the drive cylinder 4 (our company's drive is electric) can be partially reduced, which is beneficial to reducing the power loss of the drive cylinder 4.

[0028] As a preferred implementation in this embodiment, Figure 3 and Figure 4 As shown, the start-stop unit includes a square rod 21 with a screw 22 connected to the inner thread, and one end of the square rod 21 slides through the mounting plate 15 and is rotatably connected to the side end of the second large gear 18; One end of the screw rod 22 located outside the square rod 21 is rotatably connected to a U-shaped rod 23 mounted on the mounting plate 15; The second large gear 18 is rotatably arranged on the mounting plate 15 via a rotating shaft 19, a limit bar 20 is arranged on the rotating shaft 19, the second large gear 18 is slidably connected with the limit bar 20 and the rotating shaft 19, and the rotating shaft 19 is gear-connected with the end of the screw rod 22 via a connecting gear 24; The thickness of a group of the second small gears 17 close to the second large gear 18 is greater than the thickness of the second large gear 18 , and the thickness of the second large gear 18 is consistent with the thickness of the driven gear 13 .

[0029] When the transport trolley 2 rotates and dumps, the rotation of the driven gear 13 will cause the rotating shaft 19 to rotate, and the screw 22 will be driven to rotate through the connecting gear 24. The rotation of the screw 22 will drive the square rod 21 to move outward, and then drive the second large gear 18 to move outward. When the baffle fully opens the lower opening, the second large gear 18 contacts and separates from the driven gear 13. At this time, the driving chain 8 stops moving, and the transport trolley 2 continues to rotate to the set angle. After the material is completely discharged, the driving cylinder 4 drives the transport trolley 2 to return to its original position. At this time, under the coordinated drive of the gears, the second large gear 18 moves in the opposite direction and is engaged with the driven gear 13, finally driving the baffle to re-seal the opening for material discharge.

[0030] It should be noted that, first, the outer edges of the driving teeth on the second large gear 18 and the driven gear 13 are both arc-shaped, which facilitates the tooth connection between the second large gear 18 and the driven gear 13 for lateral movement; second, during the entire process, the second large gear 18 is always toothed with the second small gear 17.

[0031] As a preferred implementation manner in this embodiment, a positioning unit is further included. When the baffle completely releases the obstruction to the unloading opening of the transport trolley 2, the multiple baffles remain stationary.

[0032] As a preferred implementation in this embodiment, not shown in the figure, the positioning unit includes an elastic sleeve, the elastic sleeve is sleeved on the driving shaft 12, the inner wall of the elastic sleeve is in close contact with the outer wall of the driving shaft 12, and the elastic sleeve is fixedly mounted on the mounting frame 7; The length of the front baffle 6 is L1, the length of the horizontal U-shaped section of the driving chain 8 is L2, and L1:L2=2:1.

[0033] When the movement of the retaining plate stops (at this time, the second large gear 18 is separated from the driven gear 13), Figure 6As shown, at this time, the two parts of the front baffle 6 are evenly spread on the upper and lower parts of the left side of the driving chain 8, which is beneficial to the force balance of the driving chain 8 (its L1: L2 = 2: 1 setting is beneficial to the driving chain 8 to reach this balanced state, and is beneficial to quickly reduce the load of the driving cylinder 4), and then with the elastic sleeve locking the driving shaft 12 (at this time, the elastic sleeve uses a smaller extrusion force on the driving shaft 12 to prevent the driving chain 8 from moving), the driving chain 8 can be kept stationary. Even if the transport trolley continues to rotate to unload the material, the driving chain 8 remains stationary. Through the setting of L1: L2 = 2: 1 and the elastic sleeve, while ensuring that the subsequent driving chain 8 can remain stationary, it also minimizes the load of the subsequent driving cylinder 4 on the driving chain 8 to run.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
