[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0027] like Figures 1 to 4 As shown, the belt conveyor 100 of the embodiment of the utility model includes a tail 1 and a coal cleaning assembly 2, the tail 1 includes a frame 11; the coal cleaning assembly 2 is arranged on the front side of the tail 1 and connected to the frame 11, and the coal cleaning assembly 2 has a long strip-shaped coal shoveling part 211, and the length direction of the coal shoveling part 211 intersects with the length direction of the belt conveyor 100 and the width direction of the belt conveyor 100.

[0028] The belt conveyor 100 of the embodiment of the utility model is provided with a coal cleaning assembly 2 on the front side of the tail 1, and the coal cleaning assembly 2 has a coal shoveling part 211, and the length direction of the coal shoveling part 211 intersects with the width direction and the length direction of the belt conveyor 100; when the tail 1 is moved forward, the coal shoveling part 211 can move accordingly, and then push the coal blocks or gangue to one side of the belt conveyor 100, so that there is no need to manually clean the coal blocks and gangue on the front side of the tail 1 before the tail 1 moves, so as to improve the efficiency of the excavation construction.

[0029] It can be understood that in the tunneling system, the front side of the tail 1 refers to the direction close to the tunneling machine, the tail 1 of the belt conveyor 100 is the end close to the belt conveyor, and the head is the end away from the belt conveyor, that is, the belt conveyor 100 transports coal blocks and gangue from the tail 1 to the head.

[0030] In some embodiments, the coal cleaning assembly 2 includes a shovel plate 21 and a baffle 22, the shovel plate 21 has a coal shoveling part 211, the baffle 22 is connected to the shovel plate 21, the baffle 22 is higher than the shovel plate 21, the shovel plate 21 is arranged on the front side of the baffle 22, and at least one of the shovel plate 21 and the baffle 22 is connected to the frame 11.

[0031] The shovel plate 21 can shovel up the coal blocks and gangue on the front side of the tail 1 to prevent the coal blocks and gangue from hindering the forward movement of the tail 1. The baffle 22 can block the coal blocks and gangue so that the coal blocks and gangue can be pushed toward the pedestrian side, thereby realizing the cleaning of the coal blocks and gangue.

[0032] Optionally, the upper surface of the coal shoveling portion 211 is inclined downward from the rear to the front, so that the front side of the upper surface of the coal shoveling portion 211 is closer to the ground, thereby making it easier to shovel up coal blocks and gangue.

[0033] Alternatively, if Figure 1 and Figure 2 As shown, one side of the belt conveyor 100 is the pedestrian side, the shovel plate 21 and the baffle plate 22 are both in the shape of long strips, and one end is connected to the frame 11 of the tail 1, and the other end is inclined from the back to the front toward the direction away from the pedestrian side, and the coal shovel part 211 is the front part of the shovel plate 21; as the tail 1 moves forward, the coal shovel part 211 can clean the coal blocks and gangue on the front side of the tail 1 to the pedestrian side of the belt conveyor 12. After the forward movement of the tail 1 is completed, the construction personnel can process the coal blocks and gangue cleaned to the pedestrian side, thereby eliminating the need to delay the forward movement time of the tail 1, thereby improving the excavation construction efficiency.

[0034] In some embodiments, the coal cleaning assembly 2 further includes a plurality of shovel teeth 23 , which are disposed at the front side of the coal shoveling portion 211 and connected to the coal shoveling portion 211 , and are spaced apart along the length direction of the coal shoveling portion 211 .

[0035] By providing the shovel teeth 23, the shovel teeth 23 can separate the coal blocks when shoveling the coal blocks, thereby reducing the resistance of the shovel plate 21 when shoveling the coal blocks, thereby being more conducive to cleaning the coal blocks.

[0036] Optionally, the shovel teeth 23 are made of wear-resistant steel plates.

[0037] Optionally, the upper surface of the front side of the shovel teeth 23 is inclined downward from rear to front, so that the upper surface of the front side of the shovel teeth 23 is closer to the ground, so as to facilitate shoveling coal blocks and gangue.

[0038] In some embodiments, the plurality of scoop teeth 23 are evenly arranged along the length direction of the coal scooping portion 211 .

[0039] By evenly arranging the shovel teeth 23, when the coal cleaning assembly 2 moves forward with the random tail 1, multiple shovel teeth 23 contact the coal block at the same time, so that the coal shovel part 211 is evenly stressed along its length direction, which can reduce the probability of damage to the coal shovel part 211 due to local large force, thereby extending the service life of the coal cleaning assembly 2.

[0040] In some embodiments, the shovel teeth 23 are detachably connected to the shovel plate 21 .

[0041] Since the scraper teeth 23 are severely worn when scrapping coal blocks and gangue, they can be replaced when they are damaged, thereby preventing the coal cleaning assembly 2 from being scrapped due to damage to the scraper teeth 23 and extending the service life of the coal cleaning assembly 2.

[0042] Alternatively, if Figure 2 As shown, the shovel teeth 23 are connected to the coal shoveling part 211 through a bolt assembly.

[0043] In some embodiments, the coal cleaning assembly 2 further includes a connecting member 24 , the shovel plate 21 and the baffle plate 22 are both connected to the connecting member 24 , and the connecting member 24 is detachably connected to the frame 11 .

[0044] By providing the connecting piece 24, the shovel plate 21 and the baffle plate 22 are both connected to the frame 11 through the connecting piece 24, which can improve the convenience of installing the coal cleaning assembly 2. In addition, the connecting piece 24 is detachably connected to the frame 11, and the coal cleaning assembly 2 can be installed on any belt conveyor 100 that needs to clean coal blocks and gangue; at the same time, the connecting piece 24 is detachably connected to the frame 11, and the coal cleaning assembly 2 can be replaced when it is damaged.

[0045] Optionally, the shovel plate 21 and the baffle plate 22 are both welded and fixed to the connecting member 24 .

[0046] Optionally, the connecting member 24 is in a plate shape, and the connecting member 24 is connected to the frame 11 via a bolt assembly.

[0047] In some embodiments, the coal cleaning assembly 2 further includes a support rod 25 , one end of the support rod 25 is connected to the baffle 22 , and the other end of the support rod 25 is connected to the connecting member 24 .

[0048] By providing the support rod 25 , when the tail 1 moves forward, the shovel plate 21 is subjected to a reaction force while shoveling up coal blocks and gangue. The support rod 25 can provide support for the baffle plate 22 and the shovel plate 21 to improve the stability of the baffle plate 22 and the shovel plate 21 .

[0049] Alternatively, if Figure 2 As shown, the connecting member 24 is in the shape of an elongated strip and extends along the width direction of the belt conveyor 100. A plurality of support rods 25 are arranged at intervals along the width direction of the belt conveyor 100. The plurality of support rods 25 are welded and fixed to the connecting member 24 to provide stable support for the baffle 22 and the shovel plate 21.

[0050] In some embodiments, Figure 3 As shown, the tail 1 also includes a belt 12, which is movably connected to the frame 11; the belt conveyor 100 also includes a coal guide plate 3, one side of the coal guide plate 3 is arranged above the baffle 22 and connected to the baffle 22, and the other side of the coal guide plate 3 extends to the bottom of the belt 12.

[0051] Since there is a triangular gap between the baffle 22 and the belt 12 of the tail 1, coal lumps and gangue may fall from the belt conveyor 100 into the gap due to the coal return phenomenon, but the coal cleaning assembly 2 cannot clean the coal lumps and gangue falling into the gap when the tail 1 moves forward, thereby affecting the forward movement of the tail 1. By providing a coal guide plate 3, the coal guide plate 3 covers the above gap, when coal lumps or gangue fall from the belt 12, they can fall on the coal guide plate 3, thereby reducing the impact on the forward movement of the tail 1.

[0052] Optionally, the upper surface of the baffle 22 is lower than the lower surface of the belt 12, that is, the front side of the coal guide plate 3 is not higher than the rear side of the coal guide plate 3, so as to prevent coal blocks or gangue from falling on the coal guide plate 3 and sliding along the coal guide plate 3 to the bottom of the belt 12.

[0053] Optionally, one side of the coal guide plate 3 is fixedly connected to the baffle 22 by welding or bolting.

[0054] In some embodiments, Figure 4 As shown, the upper surface of the coal guide plate 3 is arranged to be gradually inclined downward in a direction from rear to front.

[0055] Through the above arrangement, the coal blocks or gangue dropped onto the coal guide plate 3 by the belt conveyor 100 can slide along the coal guide plate 3 to the front side of the baffle 22, thereby making it easier for the coal cleaning assembly 2 to clean the coal blocks or gangue.

[0056] The tunneling system of the embodiment of the utility model includes a tunneling machine, a belt transfer machine and a belt conveyor 100. The belt transfer machine is arranged at the rear side of the tunneling machine. The belt conveyor 100 is the belt conveyor 100 of any of the above-mentioned embodiments. The belt conveyor 100 is arranged at the rear side of the belt transfer machine. The belt conveyor 100 is connected to the tunneling machine through the belt transfer machine.

[0057] When the tunnel boring machine is excavating forward, the belt conveyor moves forward accordingly. After the tunnel boring machine has excavated forward for a certain distance, the tail 1 of the belt conveyor 100 needs to be moved forward to keep the belt conveyor 100 docked with the belt conveyor.

[0058] Through the above arrangement, when the tail 1 of the belt conveyor 100 moves forward, the cleaning component can push the coal blocks and gangue on the front side of the tail 1 to the pedestrian side of the tunneling system, so that before the tail 1 moves forward, there is no need to manually clean the coal blocks or gangue on the front side of the tail 1, thereby improving the efficiency of tunneling construction.

[0059] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
