Description
The technical field is as follows:
the utility model relates to a coal mining equipment technical field especially relates to a bold coal is breaker in advance for colliery is elevating conveyor in pit.
Background art:
the reversed loader is the reversed loading equipment of a fully mechanized coal mining face coal conveying system, coal of a face scraper conveyor is reversed loaded onto a roadway belt conveyor, the reversed loader is a heavy scraper conveyor capable of longitudinally moving integrally, a small amount of large coal still exists because the reversed loader is positioned at the upstream of coal transportation, the impact of the large coal on the reversed loader is large, equipment is possibly blocked due to the fact that the reversed loader enters downstream equipment (such as a crusher), production accidents are caused, and normal production progress is influenced.
The utility model has the following contents:
an object of the utility model is to provide a bold coal is breaker in advance for colliery elevating conveyor in pit.
The content of the utility model is as follows: a large coal pre-crushing device for a coal mine underground reversed loader comprises a horizontally arranged reversed loader, an outer portal frame is fixedly installed on a conveying groove of the reversed loader, an electric push rod is fixedly installed on a top plate of the outer portal frame, the bottom end of a telescopic rod of the electric push rod is fixedly connected with a top plate of an inner portal frame, slide rails are vertically installed on two side plates of the inner portal frame, rails are vertically installed on the inner walls of the two side plates of the outer portal frame and are in sliding connection with the slide rails, slide columns are horizontally and fixedly installed at two side positions of the bottom end of each inner portal frame, the large coal pre-crushing device further comprises a pair of symmetrically arranged sandwich plates, sliding grooves are formed in the front end and the rear end of each sandwich plate along the length direction, the slide columns are in sliding connection with the sliding grooves, the top ends of the sandwich plates are hinged with a horizontally arranged central shaft, two ends of the central shaft are fixedly connected with the inner wall of the outer portal frame, the tail end of the plywood is fixedly connected with a crushing plate downwards, pre-crushing spikes are arranged on the inner sides of the crushing plates, and when the crushing plates are in a closed state, the lowest ends of the crushing plates are located in a conveying groove of the reversed loader.
The utility model has the advantages that: the utility model discloses simple structure installs automatic bold coal pre-crushing mechanism on elevating conveyor, starts electric putter during the use, utilizes electric putter's straight reciprocating motion to drive the periodic opening and the closure of breaker to play the effect of broken bold coal, replaced traditional manual operation, work efficiency is high, guarantees the normal clear of production.
Description of the drawings:
FIG. 1 is a schematic view of the structure of the present invention;
FIG. 2 is a front view of the present invention;
fig. 3 is a perspective view of the present invention;
in the figure, a reversed loader 1, an outer portal frame 2, an electric push rod 3, an inner portal frame 4, a track 5, a sliding column 6, a plywood 7, a chute 8, a central shaft 9, a crushing plate 10 and a pre-crushing spine 11.
The specific implementation mode is as follows:
as shown in fig. 1 to 3, a lump coal pre-crushing device for a coal mine underground reversed loader comprises a reversed loader 1 which is horizontally arranged, an outer portal frame 2 is fixedly arranged on a conveying groove of the reversed loader 1, an electric push rod 3 is fixedly arranged on a top plate of the outer portal frame 2, the bottom end of a telescopic rod of the electric push rod 3 is fixedly connected with a top plate of an inner portal frame 4, slide rails are vertically arranged on two side plates of the inner portal frame 4, rails 5 are vertically arranged on inner walls of the two side plates of the outer portal frame 2, the rails 5 are slidably connected with the slide rails, slide columns 6 are horizontally and fixedly arranged on two side positions of the bottom end of each inner portal frame 4, a pair of symmetrically arranged sandwich plates 7 are further included, sliding grooves 8 are arranged at the front and rear ends of the sandwich plates 7 along the length direction, and the slide columns 7 are slidably connected with the sliding grooves 8, the top of plywood 7 is articulated with the center pin 9 that the level set up, the both ends of center pin 9 with outer portal frame 2's inner wall fixed connection, plywood 7's the downward fixedly connected with breaker 10 in end the inboard of breaker 10 all installs broken spine 11 in advance, works as breaker, 10 are in the closed condition, the least significant end of breaker 10 is located the conveyer trough of elevating conveyor 1.
The working principle is as follows: when the coal breaker works, when large coal blocks pass through the conveying groove of the transfer conveyor 1, the breaking plates 10 which are periodically closed and opened can pre-break the large coal blocks, so that the large coal blocks are prevented from entering downstream equipment.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
