Drag conveyor 100 according to embodiments of the present invention is described below with reference to Fig. 1-Fig. 3.
As shown in Figure 1-Figure 3, drag conveyor 100 according to embodiments of the present invention, including：Frame 110, scraper chain 120
And tail-pulley device 130.It should be noted that scraper chain 120 can follow in the presence of drive device along corresponding track
Ring is moved, and goods (such as coal, ore etc.) can be transported to corresponding position by scraper chain 120 during motion.
Specifically, scraper chain 120 is located in frame 110.As shown in figures 1 and 3, tail-pulley device 130 can include wheel
Axle 131 and wheel body 132, wheel shaft 131 are located in frame 110, to support wheel body 132.Wheel body 132 is pivotly outer to be enclosed on wheel shaft
On 131, that is to say, that wheel body 132 can rotate on wheel shaft 131.Scraper chain 120 contacts with the portion perimeter wall of wheel body 132
To drive wheel body 132 to rotate using the frictional force between scraper chain 120 and wheel body 132.
It should be noted that wheel body 132 is driven member, it primarily serves support and the effect being oriented to, and utilizes scraper chain 120
Frictional force between the periphery wall of wheel body 132 makes scraper chain 120 drive wheel body 132 to rotate, to substitute correlation technique middle scraper chain
Engaged the gear teeth on wheel body with scraper chain in a manner of scraper chain is driven wheeling thereof, so as to simplify tail-pulley device
130 structures, reduce production cost.In addition, compared with correlation technique, without again by reduce the diameter dimension of wheel shaft 131 come
Assembly space is merged out for the engagement of scraper chain 120 and wheel body 132, and then the size of wheel shaft 131 can be increased to improve wheel shaft
131 structural strength, which thereby enhance the performance of tail-pulley device 130.
