Two-degree-of-freedom sealed discharging device

Abstract

The invention provides a two-degree-of-freedom sealed discharging device. The two-degree-of-freedom sealed discharging device comprises a first conveying belt and a second conveying belt. A conveyingbelt dust cover is located on the outer side of the first conveying belt and the outer side of the second conveying belt and fixedly connected with the first conveying belt and the second conveying belt. A driving mechanism is used for driving the conveying belt dust cover to move forwards and backwards along a preset path; and a lifting mechanism is used for driving the second conveying belt to move up and down around a first hinge in the vertical direction. The unloading point of an unloading belt conveyor is adjusted in the horizontal direction and the vertical direction according to the position of a truck or the unloading point, and therefore flying dust pollution caused in the loading and unloading process can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of stockyard unloading, and in particular relates to a two-degree-of-freedom sealed unloading device. Background technique [0002] Crushing products are widely used in metallurgy, construction, coal, road construction, chemical industry and other industries, and play an important role in the industrial production process. According to the product use, they can be divided into different particle sizes. During transportation, they often need to be loaded and transported many times . [0003] The traditional loading methods include manual loading by loader, belt conveyor loading, and tank loading. Loading by the loader needs to be dug gradually, and then loaded after moving, which is inefficient and generates a lot of dust; Most of the operation is carried by belt conveyors, and the ore is transported to the transport vehicle through the belt conveyor, and the current belt conveyors are mostly fixed structures, and the...

[0003] The traditional loading methods include manual loading by loader, belt conveyor loading, and tank loading. Loading by the loader needs to be dug gradually, and then loaded after moving, which is inefficient and generates a lot of dust; Most of the operation is carried by belt conveyors, and the ore is transported to the transport vehicle through the belt conveyor, and the current belt conveyors are mostly fixed structures, and the loading position of the truck needs to be adjusted several times to align the truck with the unloading end of the belt. It is very time-consuming to adjust back and forth, the height difference of blanking is large, and the loading dust is large; the bottom of the tank silo also needs to adjust the loading position many times, and the cost of the tank silo is high and the storage capacity is small. , the existing loading system has low loading efficiency and large dust

[0004] The patent application number 201520787028.4 discloses a belt unloading device, although it can realize multi-directional unloading, but it cannot be precisely controlled, the operation is inconvenient, and the environmental protection performance is poor
