Description

Technical Field

[0001] The utility model relates to the technical field of coal mine transportation, and more specifically to an underground mining and transportation device. Background Art

[0002] A coal mine is an area where humans exploit coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal. This is an underground coal mine. After the coal mine is mined underground, transportation equipment is needed to transport the coal.

[0003] For example, the authorization announcement number CN219277479U discloses an underground coal mining and transportation device, which belongs to the technical field of transportation equipment, including a transport vehicle and an L-shaped plate installed inside the transport vehicle. A first box door is rotatably installed on the front of the transport vehicle, and a second box door is rotatably installed on the side of the transport vehicle. The tops of the first box door and the second box door are movably connected to the transport vehicle through a connecting mechanism. The interior of the transport vehicle is obliquely installed with a first pad and a second pad that cooperate with the first box door and the second box door. Through the arrangement of the first box door and the second box door, the coal screened by the L-shaped plate can be discharged from the interior of the transport vehicle respectively, avoiding the problem of the screened coal being mixed together during unloading, and no manual handling and unloading is required. At the same time, the arrangement of the first pad and the second pad installed obliquely inside the transport vehicle can speed up the discharge speed of the coal from the interior of the transport vehicle. However, the transport device has the following disadvantages during use:

[0004] In order to prevent the screened coal from being mixed together during unloading, the transport device has discharge ports on both sides of the transport vehicle. However, when unloading, personnel need to run around the transport vehicle and open the discharge ports one by one, which will greatly affect the unloading efficiency of the coal mine. Moreover, the internal structure distribution of the above-mentioned transport device is unreasonable, and the discharge ports opened are small, which will further affect the unloading efficiency of the coal mine.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Example

[0026] like Figure 1-4 As shown, an underground mining and transportation device comprises a transport vehicle 1, the inner wall of the transport vehicle 1 is fixedly connected with a screen plate 2, one side of the screen plate 2 is fixedly connected with a partition plate 3, the lower end of the partition plate 3 is fixed to the inner bottom end of the transport vehicle 1, the inner cavity of the transport vehicle 1 is divided by the partition plate 3 to form a first chamber 11 and a second chamber 12, the first chamber 11 and the second chamber 12 are both provided with a discharge port 13 on the side away from each other, the inner wall of the discharge port 13 is rotatably connected with a door stopper 14, the upper end of the door stopper 14 is fixedly connected with a connecting block 15, and one side of the connecting block 15 is provided with a limiting groove 151;

[0027] A C-shaped linkage rod 4 is provided on one side of the transport vehicle 1, and connecting rings 5 ​​are sleeved on both ends of the C-shaped linkage rod 4. The connecting rings 5 ​​are fixed to the transport vehicle 1, and locking mechanisms 6 are fixedly connected to both ends of the C-shaped linkage rod 4. One end of the locking mechanism 6 is engaged with the limiting groove 151.

[0028] When the personnel unload the coal, they pull the C-shaped linkage rod 4, which can drive the locking mechanisms 6 on both sides to disengage from the limiting grooves 151 on the connecting block 15. After the locking mechanisms 6 disengage from the limiting grooves 151, the door stops 14 on both sides of the transport vehicle 1 can be opened at the same time. After the door stops 14 are opened, the coal in the first chamber 11 and the second chamber 12 will be discharged from the discharge ports 13 on both sides at the same time, which not only ensures that the coal will not be mixed together when unloading, but also greatly improves the unloading efficiency of the coal.

[0029] Among them, the screening plate 2 is placed horizontally, and the interior of the transport vehicle 1 is divided into a relatively uniform first chamber 11 and a second chamber 12 by the partition 3. Larger discharge ports 13 can be opened on both sides of the transport vehicle 1 to correspond to the first chamber 11 and the second chamber 12, so as to further improve the unloading efficiency of the coal mine.

[0030] like Figure 1-3 As shown, the locking mechanism 6 includes a connecting ring 2 61, a latch 62, a connecting ring 3 63, a spring 64 and a metal fiber rope 65. The connecting ring 2 61 is fixedly connected to one side of the transport vehicle 1. The latch 62 passes through the connecting ring 2 61 and is movably connected. The outer circumferential surface of the latch 62 is fixedly connected to the connecting ring 3 63. One side of the connecting ring 3 63 is fixedly connected to the spring 64. The connecting ring 3 63 is sleeved on the outer circumferential surface of the latch 62 and fixed with the spring 64. One end of the latch 62 is engaged with the limiting groove 151, and the other end of the latch 62 is fixedly connected to the metal fiber rope 65. The metal fiber rope 65 is connected to the C-shaped linkage rod 4.

[0031] During use, since the latch 62 is flexibly connected to the C-shaped linkage rod 4 through the metal fiber rope 65, when the door stop 14 needs to be closed, the latch 62 can be pulled first, at which time the metal fiber rope 65 will bend and the spring 64 will be in a state of storing force. Then, when the door stop 14 is completely closed, the latch 62 is released, and the latch 62 is engaged with the limit groove 151 under the push of the spring 64, thereby locking the door stop 14. The metal fiber rope 65 will also be straightened again at this moment, preparing for the next linkage opening.

[0032] like Figure 1-2 As shown, a flexible grip sleeve 41 is fixedly connected to the outer circumferential surface of the C-shaped linkage rod 4, and the flexible grip sleeve 41 is made of rubber material.

[0033] During use, when a person pulls the C-shaped linkage rod 4, the flexible grip sleeve 41 can improve the comfort of the person during operation.

[0034] like Figure 1 and 4 As shown, the inner bottom end of the transport vehicle 1 is inclined toward both sides.

[0035] When in use, the inclined inner bottom end allows the coal mine to have the potential energy to slide downward during unloading, thereby improving the unloading efficiency.

[0036] like Figure 1 and 4 As shown, the sieve plate 2 is an inclined structure.

[0037] When in use, a person places a shovel of coal on the upper surface of the screening plate 2. The larger coal will roll down on the screening plate 2 into the second chamber 12, and the smaller coal will pass through the screening plate 2 into the first chamber 11, thereby achieving screening of the coal.

[0038] In summary, the specific working process of this scheme is as follows: when personnel unload coal, they pull the C-shaped linkage rod 4, and the C-shaped linkage rod 4 can drive the locking mechanisms 6 on both sides to disengage from the limiting grooves 151 on the connecting block 15. After the locking mechanisms 6 disengage from the limiting grooves 151, the door stops 14 on both sides of the transport vehicle 1 can be opened at the same time. After the door stops 14 are opened, the coal in the first chamber 11 and the second chamber 12 will be discharged from the discharge ports 13 on both sides at the same time, which not only ensures that the coal will not be mixed together when unloading, but also greatly improves the unloading efficiency of the coal.

[0039] Among them, the screening plate 2 is placed horizontally, and the interior of the transport vehicle 1 is divided into a relatively uniform first chamber 11 and a second chamber 12 by the partition 3. Larger discharge ports 13 can be opened on both sides of the transport vehicle 1 to correspond to the first chamber 11 and the second chamber 12, so as to further improve the unloading efficiency of the coal mine.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
