The specific embodiment
Core of the present utility model provides a kind of underground conveying machinery, and this underground conveying machinery can alleviate the wearing and tearing between chain and the middle plate on the basis that guarantees low energy consumption, improve the dependability of chain and middle plate.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 3, the structural representation of the pars intermedia of the underground conveying machinery that Fig. 3 is provided for a kind of specific embodiment of the utility model.
Underground conveying machinery provided by the utility model, the intermediate portion comprises chain 21 and scraper plate 22, scraper plate 22 is arranged at chain 21, and each scraper plate 22 is parallel substantially, and under the drive of chain, move, realization is to the transportation of coal, and scraper plate 22 comprises the squeegee unit that is made of first scraper plate 221, second scraper plate 222 and the 3rd scraper plate 223, and first distance L 1 between first scraper plate 221 and second scraper plate 222 is greater than the second distance L2 between second scraper plate 222 and the 3rd scraper plate 223.
In the use, chain 21 moves under the drive of sprocket wheel (not shown), thereby drive scraper plate 22 motions that are provided with thereon, the coal that scraper plate 22 just can scrape in motion process on the middle plate (not shown) that is positioned over underground conveying machinery moves, and realizes the transportation to coal.
First distance L 1 between first scraper plate 221 and second scraper plate 222 is greater than the second distance L2 between second scraper plate 222 and the 3rd scraper plate 223, like this, can be on the basis that reduces underground conveying machinery open circuit loss, reduce the wearing and tearing between chain 21 and the middle plate, improve the reliability of chain 21 work, prolong the application life of chain 21 and middle plate; On the other hand, as long as suitably control the length of first distance L 1, can also be in the increase that reduces each position linear mass of underground conveying machinery, thereby reduce the increase of underground conveying machinery open circuit loss, reduce on the basis of its use cost, improve the reliability of the support of 22 pairs of chains 21 of scraper plate, prevent effectively chain 21 under the effect of gravity in sagging the making plate contact with chain 21, alleviate the wearing and tearing between plate and the chain 21, improve the dependability of chain 21 and middle plate, prolong the service time of chain 21.
In a kind of specific embodiment, as shown in Figure 2, in order to prevent that further first scraper plate 221 from contacting with middle plate under the action of gravity of himself with chain 21 between second scraper plate 222, can also between first scraper plate 221 and second scraper plate 222, support scratch board 23 be set, the length of support scratch board 23 is less than the length of scraper plate 22, support scratch board 23 is installed on chain 21, and parallel substantially with scraper plate 22.
In the course of work, support scratch board 23 moves under the effect of chain 21 together with scraper plate 22, and support scratch board 23 scrapes the coal motion together with scraper plate 22, the transportation of the coal of plate in realizing being opposite to.
As can be seen, chain 21 between 23 pairs first scraper plates 221 of support scratch board and second scraper plate 222 further supports, prevented that effectively the chain 21 between the two from contacting with middle plate under the effect of its gravity, thereby avoided the friction between the two, chain and middle plate have been protected, on the other hand, because the size of support scratch board 23 is less, and has a lighter quality, the recruitment of unit length of pars intermedia that the underground conveying machinery that support scratch board 23 caused is set on chain 21 is less, guaranteed the open circuit loss that underground conveying machinery is lower, simultaneously, because the size of support scratch board 23 is less, after the installation, its left and right sides does not contact with the ledge (not shown) of underground conveying machinery, thus the wearing and tearing between scraper plate 22 and ledge when having reduced effectively by bending section, improve the application life of underground conveying machinery, reduced the replacing number of times of support scratch board 23; The setting of support scratch board 23 has also increased the quantity of scraper plate 22, thereby has improved year coal efficient of underground conveying machinery.
