Abstract
Description
Technical Field
[0001] This application relates to the technical field of conveying equipment, for example, to a tail end for a mine conveying system and a mine conveying system. Background Art
[0002] In the related art, rollers and a belt are provided at the tail end, and the belt is arranged on the rollers. The belt drives the movement of materials to achieve the transfer of materials.
[0003] In the disclosed implementation process, the following problems exist in the material transmission process:
[0004] Since the tail end is an intermediate transfer mechanism in the conveyor, the tail end needs to connect the upstream equipment and the downstream equipment to achieve the transfer of materials. Since the rollers are evenly distributed, and the material passing channel formed by the rollers needs to receive the upstream materials, the constructed width is greater than the size of the discharge end of the upstream equipment. When the tail end transfers materials to the downstream equipment, it will cause problems such as unsmooth material conveyance at the connection with the downstream equipment, and then cause the belt to get stuck, affecting the conveying efficiency. Especially when applied to the connection with a turning transportation mechanism, this problem is more prominent.

The belt support frames are arranged on the walking frames 340, and the belt is wound around the belt support frames. The front driving assembly 310, the front tensioning assembly 320, the plurality of walking frames 340, the auxiliary driving assembly 360, the rear tensioning assembly 370, and the rear driving assembly 380 are connected in sequence to form a walking chassis. The crawler chain 350 is wound around the walking chassis, and the walking chassis drives the transition conveying unit 302 to move. Among them, the auxiliary driving assembly 360 is arranged in the middle of the standard conveying unit 304. Since the standard conveying unit 304 has a certain length, by arranging the auxiliary driving assembly 360 at the middle position of the length, the traveling power of the standard conveying unit 304 is improved. And, the heights and structures of the plurality of belt support frames are the same. Among them, the height of the belt support frames on one side of the transition conveying unit 302 is the same as that of the belt support frames of the standard conveying unit 304.
[0081] Optionally, the mine conveying system 1 can be provided with multiple sets of standard conveying units 304 according to the requirements of the conveying length, thereby extending the conveying length of the mine conveying system 1 to meet the requirements of different mine scenarios.
[0082] Optionally, in combination with Figure 7 as shown, the mine conveying system 1 further includes a head 400 and a secondary tail 500. The head 400 is arranged at the other end of the standard conveying unit 304. The secondary tail 500 adopts the tail 200 of any of the above embodiments. The tail 200 connected to the scraper crusher reloader 100 is the main tail 200 of the mine conveying system 1. In combination with Figure 5 as shown, the secondary tail 500 is connected to the head 400 through an external connection interface 280.
[0083] Optionally, in combination with Figure 6 as shown, the tail 200 of any of the above embodiments can also be connected to a steering mechanism 600 through an external connection interface 280 to facilitate the movement of the mine conveying system 1. The steering mechanism 600 includes tires.
