Sealing device for preventing mine filling gravel from splashing

Abstract

The utility model relates to the technical field of mining production, in particular to a sealing device for preventing mine filling gravel from splashing, and aims to solve the problems that when a mine is filled at present, due to the lack of a blocking device, the filling gravel is usually easily scattered on a belt from a discharging groove and splashes out towards the two sides, and the working efficiency is high. And the problems of waste of gravel materials and difficulty in cleaning are solved. The device is mainly composed of a blanking groove bottom plate, a connecting plate, a closing plate, a pressing plate, a limiting plate and the like, and the connecting plate, the closing plate, the pressing plate and the like of the device are integrally installed at the lower positions of the two sides of a blanking groove in the tail of a belt conveyor, so that the closing plate can conveniently block gravel which falls on a belt and splashes to the ground on the two sides of a belt corridor; and therefore, the phenomena of material waste and time-consuming and labor-consuming cleaning caused by the fact that the gravels are scattered on the belt through the discharging groove and are splashed out towards the two sides during mine filling are greatly avoided, and the overall efficiency of mine filling is effectively ensured.

Description

TECHNICAL FIELD

[0001] The utility model relates to mining production technical field, concretely relates to a closed device of preventing mine filling sandstone splashing. BACKGROUND

[0002] When filling to the goaf, sandstone is mixed by sand bin, disc feeder, belt conveyor, vibrating screen, discharging chute, belt conveyor, discharging chute, belt conveyor, excessive sand bin, quantitative feeder, sandstone, cement, water, and the mixed barrel of uniform mixing according to certain proportion, underground pipeline enters to the goaf, due to the height difference of discharging chute and the elasticity of belt, sandstone gradation is low and light in weight, when sandstone is scattered from discharging chute to the belt, part sandstone will splash to the ground of both sides' belt corridor, is easy to cause material waste and is difficult to clean, seriously increases the operation labor intensity, and influences the field environment health, therefore, it is necessary to further optimize the device of preventing sandstone splashing when filling to the mine, so as to ensure the good material of filling sandstone.

[0013] The utility model is further described below in connection with the drawings and specific embodiment.

[0014] As shown in Figs. 1-2 A kind of closed device for preventing mine filling sandstone splashing, including blanking groove 7, the bottom of blanking groove 7 is equipped with belt conveyor 9, the bottom of blanking groove 7 is connected with blanking groove bottom plate 1, blanking groove bottom plate 1 bottom is equipped with connecting plate 2, connecting plate 2 is detachably connected with closure plate 3.

[0015] The bottom of connecting plate 2 is equipped with multiple pressing plates 4, the top of closure plate 3 is equipped with the limit plate 5 matched with the pressing plate 4, and limit plate 5 and the pressing plate 4 are detachably connected by bolt 6.

[0016] Connecting plate 2 is made of 2mm ordinary steel plate, to connect blanking groove 7 and closure plate 3, also can prevent a small amount of sandstone splashing.

[0017] Closure plate 3 is made of 16mm thick rubber, rubber has good wear resistance and softness, can prevent sandstone splashing, and also can protect belt conveyor from being scratched during operation.

[0018] The pressing plate 4 is L-shaped and made of 5mm ordinary steel plate, and is welded in the middle of the connecting plate 2, and is used to fix the top of the closing plate 3 to the bottom of the connecting plate 2, and a square hole is formed in the bottom of the pressing plate 4 for inserting the limiting plate 5.

[0019] The limiting plate 5 is made of 5mm ordinary steel plate, and is welded in the bottom of the connecting plate 2, and is used to prevent the upward movement of the closing plate 3, and a square hole is formed in the middle of the limiting plate 5 for inserting the bolt 6.

[0020] The bolt 6 is composed of an iron chain and a plug plate, the iron chain is welded on the connecting plate 2, and the plug plate of the bolt 6 is inserted into the hole of the limiting plate 5 to fix the pressing plate 4 firmly.

[0021] In the specific use, the closing device is installed below the both sides of the discharge chute 7 at the tail of the belt conveyor 9, the connecting plate 2 is used to connect the discharge chute 7 and the closing plate 3, the closing plate 3 is used to prevent the sand and stone from falling on the belt and splashing to the ground on both sides of the belt gallery, the pressing plate 4 is used to fix the top of the closing plate 3 to the bottom of the connecting plate 2, the limiting plate 5 prevents the upward movement of the closing plate 3, and the bolt 6 is used to fix the pressing plate 4 firmly, by installing the closing device below the both sides of the discharge chute 7 at the tail of the belt conveyor 9, the sand and stone falling on the belt through the discharge chute 7 and splashing to both sides is effectively prevented, the phenomenon that the sand and stone falling on the belt through the discharge chute 7 and splashing to both sides causes material waste and time-consuming and laborious cleaning during the filling of the mine is greatly avoided, the overall efficiency of the mine filling is effectively ensured, therefore, the device has good practicability.
