Abstract
The utility model discloses a coal storage shed blanking and feeding device, which comprises a blanking chute (2) and a movable raw coal feeder (3), wherein the blanking chute (2) is cut into an upper part and a lower part along the diameter direction; a movable hydraulic flashboard (5) is arranged between the upper part and the lower part; the problems that in the prior art, when raw coal is fed, the movable raw coal feeder (3) must be aligned to a raw coal feeding port, raw coal enters the movable raw coal feeder (3) from the feeding port, a hollow state is easily formed in the feeding process, feeding is not uniform, a fluffy bin is caused, and threat to equipment and personal safety is caused are solved.
Description
Technical Field
The utility model belongs to fortune coal technique especially relates to a store up coal canopy unloading feeder.
Background
Raw coal feeding of a coal storage shed of a coal mine is realized by pushing raw coal to a feeding port by means of external force (such as a bulldozer and other machinery), the feeding port conveys the coal to a fixed raw coal belt conveyor through a feeding chute and a movable raw coal feeder, and the coal is returned to a coal preparation plant for washing, and the coal preparation plant adopts a mode of combining the movable raw coal feeder and a fixed raw coal belt conveyor when the raw coal belt conveyor is used for conveying the raw coal of the coal storage shed and is connected with the movable raw coal feeder through the feeding chute; conveying raw coal to a movable raw coal feeder through a feeding chute; then conveying the coal to a fixed raw coal belt conveyor; the disadvantages are that: when raw coal is fed, the movable raw coal feeder is required to be aligned to a raw coal feeding port, raw coal enters the movable raw coal feeder from the feeding port, a hollow state is easily formed in the movable raw coal feeder in the feeding process, feeding is not uniform, a fluffy bin is caused, and threat to equipment and personal safety is caused.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem be: the utility model provides a store up coal canopy unloading feeder to when solving the raw coal unloading, portable raw coal batcher must aim at the raw coal feed opening, and the raw coal gets into portable raw coal batcher by the feed opening, and at the unloading in-process, form the cavity state easily in portable raw coal batcher, the unloading is inhomogeneous, causes fluffy storehouse, causes the threat scheduling problem to equipment and personal safety.
The utility model adopts the technical proposal that:
a blanking and feeding device of a coal storage shed comprises a blanking chute and a movable raw coal feeder, wherein the blanking chute is cut into an upper part and a lower part along the diameter direction; a movable hydraulic flashboard is arranged between the upper part and the lower part.
The hydraulic gate plate is fixedly connected with the telescopic end of the hydraulic oil cylinder; the hydraulic oil cylinder is connected with the actuating mechanism.
The cutting opening is positioned at the middle lower part of the blanking chute.
The utility model has the advantages that:
on the basis of the prior art, the utility model cuts the blanking chute into an upper part and a lower part along the diameter direction; a movable hydraulic flashboard is arranged between the upper part and the lower part; the hydraulic gate is opened or closed by operating the hydraulic cylinder to control whether the raw coal enters the movable raw coal feeder or not; the control of the position and the coal quantity of raw coal on the movable raw coal feeder is realized, and the problems that in the prior art, raw coal enters the movable raw coal feeder through a feeding chute during feeding, a hollow state is easily formed in the feeding process, feeding is not uniform, a fluffy bin is caused, and threat to equipment and personal safety is caused are solved.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the connection between the hydraulic gate plate and the hydraulic cylinder of the present invention;
fig. 3 is a schematic diagram of the prior art structure of the present invention.
Detailed Description
A blanking and feeding device of a coal storage shed comprises a blanking chute 2 and a movable raw coal feeder 3, wherein the blanking chute 2 is cut into an upper part and a lower part along the diameter direction; a movable hydraulic gate plate 5 is arranged between the upper part and the lower part.
The cutting position is positioned at the middle lower part of the feeding chute 2; the coal feeder aims to temporarily store raw coal on the upper part of the feeding chute 2, and avoid a hollow state and uneven feeding to cause a fluffy bin.
The hydraulic gate 5 is fixedly connected with the telescopic end of the hydraulic oil cylinder 7; the hydraulic oil cylinder 7 is connected with the actuating mechanism 6; the actuating mechanism 6 comprises an oil pump, an oil pump hydraulic oil pipeline, a control switch and other devices; in order to prevent the hydraulic oil cylinder 7 from shaking in the operation process, a frame 8 can be added on the hydraulic oil cylinder 7, and the hydraulic oil cylinder 7 is fixed on the frame 8.
During blanking, the movable raw coal feeder 3 is aligned to the idle position of the fixed raw coal belt conveyor 4, the hydraulic oil cylinder 7 is started through the control switch, and the hydraulic gate 5 is opened; the raw coal 1 is conveyed to a coal preparation plant to be washed through the empty position where the raw coal enters the fixed raw coal belt conveyor 4 through the discharging chute 2 and the movable raw coal feeder 3, the hydraulic gate 5 is closed by controlling the action of the hydraulic oil cylinder 7 after the execution is finished, and the raw coal is forbidden to enter the fixed raw coal belt conveyor 4 through the discharging chute 2 and the movable raw coal feeder 3.
Claims (3)
1. The utility model provides a store up coal canopy unloading feeder, it includes unloading chute (2) and portable raw coal batcher (3), its characterized in that: the blanking chute (2) is cut into an upper part and a lower part along the diameter direction; a movable hydraulic flashboard (5) is arranged between the upper part and the lower part.
