In order to achieve the purpose, the technical scheme includes that scraper conveyors for coal mines comprise machine heads, middle troughs and machine tails, each middle trough is composed of a ledge, a trough middle plate and a trough bottom plate, a plurality of discharge openings are formed in the trough middle plate, each discharge opening is provided with a discharge plate, each discharge plate is connected with a driving mechanism, scraper chains are arranged on the trough middle plate and the trough bottom plate and driven by the machine heads and the machine tails, and a plurality of scrapers are arranged on the scraper chains.
The technical proposal of the invention also has the following characteristics,
the scraper chain can be a middle double chain, an edge double chain, a single chain or a triple chain.
The driving mechanism is a hydraulic cylinder, and a base of the hydraulic cylinder is fixed on the groove side.
The scraper chain is double-chain, the groove middle plate and the both sides of groove bottom plate all are provided with the scraper chain passageway of indent, two inboard below in middle part groove all are provided with L shape grooves, and every scraper chain is located the L shape groove below that corresponds.
And the transition groove bottom plates of the machine head and the machine tail are provided with discharge ports.
The scraper conveyors for coal mines have the advantages that the scraper conveyors for coal mines are composed of double-layer structures, the upper layer and the lower layer are transportation systems, coal and gangue simultaneous mining and separate transportation is realized from the source and the link, the problems of simultaneous mining and separate transportation of coal and gangue are solved, the gangue content of raw coal is reduced, and the mine transportation and washing cost is reduced.
Drawings
FIG. 1 is a schematic structural view of coal mining scraper conveyors of the present invention;
fig. 2 is a sectional view of fig. 1.
In the figure: 1. the device comprises a middle groove, 2 groove bottom plates, 3 scraper chain channels, 4 groove middle plates, 5 stripper plates, 6 scraper chains, 7 driving mechanisms, 8 scrapers and 9L-shaped grooves.
Detailed Description
The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and the detailed description.
As shown in figure 1, the scraper conveyors for coal mines comprise a machine head, a middle trough and a machine tail, wherein the middle trough is composed of a ledge 1, a trough middle plate 4 and a trough bottom plate 2, the trough middle plate is provided with a plurality of discharge openings, each discharge opening is provided with a discharge plate 5, each discharge plate 5 is connected with a driving mechanism 7, scraper chains 6 are arranged on the trough middle plate 4 and the trough bottom plate 2, the scraper chains 6 are driven by the machine head and the machine tail, and a plurality of scrapers 8 are arranged on the scraper chains 6.
It should be noted that, similar to the existing scraper conveyor, the coal mine scraper conveyors of the present invention also include a nose portion, a middle trough, and a tail portion, wherein the nose portion and the tail portion are used for driving the scraper chain 6, and the technical solution of the present invention is mainly improved by the middle trough portion, so that the nose portion and the tail portion are not described in too much detail.
Fig. 1 is a schematic structural diagram of a middle trough of coal mine scraper conveyors, the middle trough is a double-layer structure composed of a ledge 1, a trough middle plate 4 and a trough bottom plate 2, wherein the trough middle plate 4 and the trough bottom plate 2 are upper and lower parts, the ledge 1 is located on two sides of the trough middle plate 4 and the trough bottom plate 2, scraper chains 6 are sequentially arranged on the upper surface of the trough middle plate 4 and the lower surface of the trough bottom plate 2, the scraper chains 6 are respectively connected with driving devices (such as motors and the like) in the nose part and the tail part, the scraper chains can circularly move along the trough middle plate 4 and the trough bottom plate 2 after being driven by the driving devices, scrapers 8 cling to the trough middle plate 4 or the trough bottom plate 2 when moving along with the scraper chains 6, discharge openings are arranged in the trough middle plate 4, discharge buttons are arranged on each discharge button, the discharge plates 5 are connected with telescopic ends of the driving mechanisms 7, and the corresponding discharge openings can be closed under the action of the driving.
When the coal mining machine cuts coal, the driving mechanism 7 is started firstly, the discharge opening is ensured not to be sealed by the discharge plate 5, the cut coal falls on the middle trough plate 4, the coal on the middle trough plate 4 falls on the bottom trough plate 2 through the discharge opening under the action of the scraper 8, and finally the coal is conveyed out. When the coal mining machine cuts a rock stratum at the top, the discharge openings are sequentially blocked by the discharge plates 5 along with the gradual forward pushing of the coal mining machine, cut and mined waste rocks fall onto the groove middle plate 4, and the waste rocks on the groove middle plate 4 are conveyed out under the action of the scraper 8.
