Abstract

The utility model relates to the field of mineral processing, in particular to a feeding device. A bin is arranged on a framework, a valve is disposed below a discharge outlet of the bin, is connected with a power mechanism and reciprocates between limiting mechanisms arranged on the framework, and a projection is disposed at the front end of the valve in a traveling direction thereof. Due to the technical scheme, the valve reciprocates on the framework, and the quantity of materials dropping from the discharge outlet of the bin is controlled by means of adjusting the opening degree of the valve. The feeding device is simple in structure, reliable in operation and small in occupied space, and simultaneously, the projection arranged at the front end of the valve can be used for assisting in crushing materials remained at an opening of the valve.

Description

A kind of charging gear

Technical field

The utility model relates to the mineral manufacture field, is specifically related to a kind of charging gear.

Background technology

Continuous development along with China's mineral process technology, coal preparation plant is also more and more higher to the requirement of mechanical device, the degree of automation of mechanical device is also more and more higher, requires the equipment of each link of coal preparation technique should possess the operation stability height, high efficiency and degree of automation advantages of higher.

At present, the cash system that selects in coal preparation plant raw coal workshop changes picking lump coal into by artificial hand selection's spoil, lump coal enters former waste bin behind the artificial hand selection, then need enter the washing system through fragmentation, a feeder, a crusher and a travelling apron need be installed at lump coal storehouse end opening by system.Because equipment is concentrated, Hatch Opening is little to the ground perpendicular throw, and existing feeding device volume is big, and is highly high, can't satisfy system's installation requirement.

Summary of the invention

The purpose of this utility model provides a kind of little charging gear that takes up room, and can satisfy the new installation requirement that selects the cash system.

For achieving the above object, the utility model has adopted following technical scheme: frame is provided with feed bin, the discharging opening below of feed bin is provided with valve, and valve links to each other with actuating unit and moves back and forth between the stop gear that is provided with on the frame, and valve is provided with lug boss at the front end of its direct of travel.

By above technical scheme, valve is crank motion on frame, and what of material that feed bin discharging opening place falls are the size of opening by regulating the valves control.This charging gear is simple in structure, reliable operation, and it is little to take up room; Simultaneously, but the lug boss of valve front end setting also addi-tional crusher be trapped in the material at valve port place.

Description of drawings

Fig. 1 is the structural representation of valve open one half of this device;

Fig. 2 is the B-B direction structure scheme drawing of Fig. 1;

Fig. 3 is the structural representation of valve at the lug boss of the front end of direct of travel.

The specific embodiment

A kind of charging gear, frame 20 is provided with feed bin 10, the discharging opening of feed bin 10 below is provided with valve 30, valve 30 link to each other with actuating unit and between the stop gear of setting on the frame 20 crank motion, valve 30 is provided with lug boss 31 at the front end of its direct of travel.Actuating unit takes off movable valve 30 and moves reciprocatingly on frame 20, the inventory that the discharging opening place of the size control feed bin 10 by 30 openings that regulate the valves falls.When the discharging opening place of feed bin 10 had material lagging to stop up, actuating unit can drive valve 30 and move back and forth and clash into material, keeps the unobstructed of discharging opening.Valve 30 can obviously improve the crushing effect of valve 30 at the lug boss 31 of the front end setting of its direct of travel, guarantees that blanking is unimpeded.

Further, described lug boss 31 is hemisphere projection or triangle taper projection.

Frame 20 comprise two parallel and be positioned at the channel-section steel 21 of horizontal direction, the opening direction of its notch points to the outside of frame 20, and valve 30 is a plain plate, and the both sides of valve 30 are welded with section bar 50, section bar 50 forms notch 32 with the upper face of valve 30, shown in left-hand portion among Fig. 2.The opening direction of notch 32 points to the inboard of frame 20, and the lower wing plate of channel-section steel 21 places in the notch 32, shown in position, right side among Fig. 2, constitutes bearing fit between the lower wing plate of channel-section steel 21 and the notch 32.When actuating unit drove valve 30 motions, valve 30 drove notch 32 and slides on the lower wing plate of channel-section steel 21.

Further, section bar 50 is an angle steel, and the outside in the bight of section bar 50 is provided with gusset 51, and gusset 51 also is a dihedral.The medial surface in the bight of section bar 50 with constitute notch 32 with the upper face of valve 30, the gusset 51 of the lateral surface setting in the bight of section bar 50 is used for the intensity of stiffening profile 50, guarantees that the shape of notch 32 and position are maintained.

Be welded with on the frame 20 on the connecting panel 60, connecting panel 60 links to each other with the discharging opening place of feed bin 10, and the middle part of connecting panel 60 has the aperture, and the bore of the discharging opening of its aperture and feed bin 10 matches.Like this, connecting panel 60 does not influence material yet and falls smoothly from the discharging opening of feed bin 10 when fixing frame 20.

Actuating unit is a hydraulic actuating cylinder 40, and the cylinder body of hydraulic actuating cylinder 40 is fixed on the frame 20, and the piston rod 42 of hydraulic actuating cylinder 40 is connected with valve 30, and the oil cylinder of hydraulic actuating cylinder 40 is connected with control oil channel.Control oil channel is sent into the oil mass of oil cylinder by control, realizes the crank motion of piston rod 42, thereby pushes away, draws valve 30 to do straight reciprocating motion.

Stop gear is made of limiting stopper 22 and limiting stopper 23, and limiting stopper 22 and limiting stopper 23 lay respectively at the front and back end of valve 30 working direction, and when valve 30 was closed fully, valve 30 just position contacted with limiting stopper 22; When valve 30 was opened fully, valve 30 just contacted with limiting stopper 23.
