Description

Coal sliding device capable of automatically adjusting coal passing height

Technical Field

The utility model belongs to the technical field of coal mine equipment, and particularly relates to a coal sliding device capable of automatically adjusting the coal passing height.

Background

The coal outlet system and the panel belt conveyor of the fully mechanized mining face have two modes of level crossing and grade crossing, if the grade crossing mode is met, a crossheading belt unloading frame of the fully mechanized mining face needs to be used as an air bridge to install a coal leakage hopper for coal outlet, and the coal outlet height is fixed after the old coal leakage hopper is installed. After the fixed coal leakage hopper is installed, when the coal passing height is low, the impact on a panel belt is small, but the belt is easily blocked and damaged when large carbon blocks appear at the rear part of the coal leakage hopper; when the height of coal is high, the impact on the belt in the panel area is large, and the belt is occasionally damaged by sharp objects, which is not favorable for the normal operation of the belt conveyor in the panel area.

Disclosure of Invention

The utility model provides a coal sliding device capable of automatically adjusting the coal passing height, aiming at the problems that the belt is easy to be blocked and damaged due to the fixed coal outlet height of the existing coal leakage hopper.

The utility model adopts the following technical scheme:

the utility model provides a swift current coal device of high from coal passing, be equipped with the coal leaking fill in V type groove including the bottom, the top and the support frame of coal leaking fill pass through a plurality of bolted connection, coal leaking fill bottom is equipped with the coal chute that the cross-section is triangle-shaped, the lateral wall of the both sides of coal chute is equipped with two lugs of arranging along the coal chute bottom respectively, the lateral wall of coal leaking fill is equipped with the lug, the lateral wall of coal chute and the lateral wall of coal leaking fill are connected through two anchor chains I and anchor chain II respectively, the lug of coal chute is connected in coal chute to the one end of anchor chain I and anchor chain II, a lug with coal chute is connected to the other end of anchor chain I, another lug with coal chute is connected to the other end of anchor chain II, the bottom of coal chute and the bottom of coal chute rotate through the pivot and connect.

Furthermore, the anchor chain I and the anchor chain II are connected with the lifting lugs through U-shaped connectors.

Furthermore, the rotating shaft is welded at the bottom of the V-shaped groove at the bottom of the coal leaking hopper, and the coal leaking groove is sleeved on the rotating shaft through a sheath.

Further, the distance between the disk belts at the bottommost end and the bottom of the coal chute is 600mm and 900 mm.

The utility model has the following beneficial effects:

the utility model is applied to the coal outlet system of the fully mechanized coal mining face and the panel belt conveyor in a flyover arrangement mode. The coal chute can rapidly adjust the coal passing height at any time according to the field coal outlet condition, thereby not only ensuring the coal outlet block rate, but also reducing the damage of large objects to the panel belt, realizing the instantaneous adjustment of the coal outlet height when the large objects pass through the lower part of the coal leakage hopper occasionally, and meeting the production requirement of raw coal.

Detailed Description

The utility model is further explained with reference to the accompanying drawings.

As shown in the figure, the coal sliding device capable of automatically adjusting the coal passing height comprises a coal leakage hopper 2 with a V-shaped groove 1 in the bottom, the top end of the coal leakage hopper 2 is connected with a support frame 3 through a plurality of bolts, a coal sliding groove 4 with a triangular cross section is arranged at the bottom of the coal leakage hopper 2, two lifting lugs arranged along the bottom of the coal sliding groove 4 are respectively arranged on the side walls of two sides of the coal sliding groove 4, a lifting lug 5 is arranged on the side wall of the coal leakage hopper 2, the side wall of the coal sliding groove 4 and the side wall of the coal leakage hopper 2 are respectively connected through two anchor chains I6 and an anchor chain II 7, one ends of the anchor chains I6 and the anchor chains II 7 are connected with the lifting lug of the coal leakage hopper 2, the other end of the anchor chain I6 is connected with one lifting lug of the coal sliding groove 4, the other end of the anchor chain II 7 is connected with the other lifting lug of the coal sliding groove 4, and the bottom of the coal leakage hopper 2 and the bottom of the coal sliding groove 4 are rotatably connected through a rotating shaft 8.

The coal leaking hopper and the coal chute are connected with four anchor chains through bolts. The bolt is used as the effect of pivot, and the anchor chain plays spacing and self-adjusting back-up protection's effect.

After a rotatable coal chute is added below a large V-shaped groove of an original coal leaking hopper, the coal passing height from the lowest point of the coal chute to a panel belt is about 600mm, so that the coal block yielding rate of a working surface can be ensured, and the damage to the panel belt can be reduced. When large articles larger than 600mm pass through the coal leaking hopper on other working surfaces at the rear part of the coal leaking hopper, the rotary coal chute can be instantaneously jacked up and then smoothly passes through, and the dual functions of ensuring the smooth coal outlet of the rear working surface, ensuring the coal outlet rate of the working surface and reducing the damage to the panel belt are achieved.
