Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel engineering, and in particular relates to a slag transport mechanism of pre-supported shield equipment. Background Art

[0002] The pre-supported shield is an anchoring and protection system in tunnel engineering, which is mainly used for rock reinforcement before tunnel excavation. It uses specific equipment and technical means to pre-reinforce the rock layer in the unexcavated area before tunnel excavation to prevent risks such as collapse and deformation during the excavation process. When excavating the tunnel, a large amount of mud, slag and rock will be generated. The shield equipment generally uses the spiral conveying equipment behind the blade to continuously transport the slag out for subsequent processing.

[0003] When the slag transport mechanism of the existing pre-supported shield equipment is spirally transporting materials, the friction between the mud and the machine slot and spiral blades will cause a large energy consumption. This friction not only increases mechanical loss, but also may cause wear to the machine slot and spiral blades, affecting their service life. Due to the existence of friction resistance, the conveying speed of the slag transport mechanism will also be affected. Utility Model Content

[0004] The purpose of the utility model is to provide a slag transport mechanism for pre-supported shield equipment, which drives the conveyor belt to move through the rotation of spiral blades. The rotation of the spiral blades and the movement of the conveyor belt jointly discharge the mud and slag, reducing the contact area between the mud and slag and the inner wall of the machine trough, thereby reducing friction and mechanical loss, increasing the transportation speed, alleviating the wear of the machine trough and spiral blades by the mud and slag, and extending the service life.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A slag transport mechanism of a pre-supported shield equipment comprises a motor fixedly assembled on the top of a machine slot, a spiral blade rotatably assembled inside the machine slot, a conveyor belt is transmission-assembled at the bottom of the machine slot and below the spiral blade, a tooth groove is fixedly connected to the conveyor belt on the side opposite to the spiral blade, blocks for pushing the spiral blade are symmetrically fixedly connected to the edges of the conveyor belt at equal distances, a plurality of fixed plates are symmetrically fixedly connected to the two sides of the machine slot, a cross bar is fixedly connected between two opposite fixed plates, a gear is rotatably connected to the outer wall of the cross bar and is located on one side of the conveyor belt, and the gear is meshingly connected to the tooth groove.

[0007] The output end of the motor is drivingly connected to the spiral blade, and both ends of the machine slot are fixedly connected with outer baffles.

[0008] An inner baffle is fixedly connected to one end of the machine groove and located above the conveyor belt, and the spiral blade is rotatably connected to the inner baffle.

[0009] A fixed plate two is symmetrically and fixedly connected between the two outer baffles, and connecting rods are fixedly connected at equal distances between the two fixed plates two and below the conveyor belt.

[0010] A vertical rod is fixedly connected to the middle of the connecting rod, and one end of the vertical rod is rotatably connected to a pulley for supporting the conveyor belt.

[0011] Support rods are fixedly connected to the outer wall of the connecting rod on both sides of the vertical rod, and a scraper is fixedly connected between the two support rods and on one side of the conveyor belt.

[0012] The technical effects achieved by the present utility model are as follows: The rotation of the spiral blade pushes the conveyor belt to move. The rotation of the spiral blade and the movement of the conveyor belt jointly discharge the mud residue, reducing the contact area between the mud residue and the inner wall of the machine trough, thereby reducing the friction and mechanical loss, increasing the transportation speed, alleviating the wear of the mud residue on the machine trough and the spiral blade, and extending the service life.

[0022] According to the above structure, the sludge enters the inside of the trough 1 and falls on the conveyor belt 105. The motor 101 drives the spiral blade 107 to rotate for feeding. While the spiral blade 107 rotates, it continuously pushes the blocking block 110 forward. The blocking block 110 drives the conveyor belt 105 to continuously rotate in a cycle at the bottom of the trough 1. The conveyor belt 105 rotates in a cycle for feeding. Cooperating with the feeding of the spiral blade 107, it greatly reduces the friction between the sludge and the trough 1. The inner baffle 108 prevents the sludge from falling outside the trough 1 and the conveyor belt 105. When the conveyor belt 105 rotates, it drives the tooth groove 106 to rotate together.

The fixing plate 2 103 and the connecting rod 113 support the vertical rod 114 and the support rod 115. Through the rotation of the spiral blade 107 to push the conveyor belt 105 to move, the rotation of the spiral blade 107 and the movement of the conveyor belt 105 jointly discharge the sludge, reduce the contact area between the sludge and the inner wall of the trough 1, thereby reducing the friction and mechanical loss, improving the transportation speed, alleviating the wear of the trough 1 and the spiral blade 107 by the sludge, and extending the service life.

[0023] The working principle of the present utility model is as follows: The sludge enters the inside of the trough 1 and falls on the conveyor belt 105. The motor 101 drives the spiral blade 107 to rotate for feeding. While the spiral blade 107 rotates, it continuously pushes the blocking block 110 forward. The blocking block 110 drives the conveyor belt 105 to continuously rotate in a cycle at the bottom of the trough 1. The conveyor belt 105 rotates in a cycle for feeding. Cooperating with the feeding of the spiral blade 107, it greatly reduces the friction between the sludge and the trough 1. The inner baffle 108 prevents the sludge from falling outside the trough 1 and the conveyor belt 105. When the conveyor belt 105 rotates, it drives the tooth groove 106 to rotate together. The tooth groove 106 drives the gear 112 to rotate. The rotation of the gear 112 helps to improve the smoothness of the rotation of the conveyor belt 105. The cross bar 111 and the fixing plate 102 support the gear 112. The pulley 109 supports the conveyor belt 105 below the trough 1 to prevent it from sagging. The vertical rod 114 supports the pulley 109. The scraper 116 can scrape off the residual sludge on the outer wall of the conveyor belt 105. The support rod 115 supports the scraper 116. The fixing plate 2 103 and the connecting rod 113 support the vertical rod 114 and the support rod 115.

[0024] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
