Description

In the jraxpoitovBax forerunner to load skips about coming to the dosage bunkers, equipped with a high-level independent airway, the control of the valve is very difficult and has a lot of problems.

In the proposed device, a blocking device is used, which ensures the automatic alternate opening of the gates during the landing of the displacement carriage, achieved by using ropes with pickles and landing bore skids with aagvors of the bunkers.

On and 2 in two projections, a general view of the device is depicted, FIG. 3 shows the section along A-A $ ig.1 with the dispenser in the extreme right position.

The device consists of a dispenser I, a right dispensing bin 2, a left dispensing hopper 3 and landing carriages 4.

The receiving hopper 5 of the dispenser is installed under the bunker, and the tipper is fed directly to the coal stove.

This funnel is a two-arm chute equipped with a sector shutter 6. The shutter, while in its extreme positions, always overlaps one of the hoses of the funnel, and the other always remains open.

The dispenser has two outlets, which adjoin the right 2 and left 3 dosing bins.

Dosing bunkers are equipped with a shutter interlocked with the valve b dispenser. The opening of the gates is made by the weight of the skip acting on the ropes, reduced by the landing carriages 4.

When approaching under loading, skip sits on the landing carriage 4, in which the ends of the ropes 7 are fastened through shock absorbers and struts. The second ends of these ropes carry on themselves counterweights 8.

Ropes 7 go around the dinners of oactors 9 and are fixed on these dinners with special clamps. The attachment point of the ropes is shown in FIG.

Following the movement of the skip, the carriage 4 goes down and there is no rope 7 behind it, which in turn rotates the sectors 9 in the direction indicated by the arrows.

In this case, the levers 10, turning together with the sectors, act on the pull II connected with the levers 12 of the valve gate 13 of the dosing bin.

The shutter opens, and at the same time the pan is pushed out. The pan is connected to the frame 15 fixed on the axis of rotation of the sectors, as a result of which the pan 15 rotates at the same time and rotates 15 when the pan is opened and closing the dosing bin shutter.

At the time of opening of the dosing of the dosing bin, the shutter of the receiving hopper of the dispenser is switched by means of ropes 17, fixed with one ends at the sector lunch and the other ends to the shutter of the receiving hopper of the dispenser.

Figure 1 shows the position of the boot device at the time of loading the right skip.

As can be seen in FIG. 3, the shutter b completely covers the right sleeve of the receiving hopper 5 of the dispenser.

This position of the shutter b corresponds to the position of full opening of the shutter 13 of the right dosing bin at the time of loading the right-. go-skip.

At the same time, through the left sleeve of the receiving hopper of the dosing unit, coal enters the left dosing bin.

Kinematics of the lever mechanism of the valve bolt 13 output | nvna so that the opening of the shutter 13 occurs with a slowdown compared with the closing speed of the gate b receiving funnel dose 95815

- 2 tori, which close the glimmer of 20 °.

Thanks to this, an accurate cut-off of the coal in the dispenser, the so-called. Coal from the dosing bin begins to pour into the skip only after the valve B completely closes the coal outlet from the receiving hopper of the dispenser.

During the return movement of the right skip, the counterweight 8 is lowered down, turning through the ropes 7 ceKTOj 9, as a result of which the shutter of the right dosing bin closes.

With this, the lever 10 goes beyond the dead center, with the result that the shutter 13 of the metering hopper oyazapiraats. Shutter opening can occur only through the effect of oxide on the ropes 7.

Rope 17 at the time of rotation of sector 9 is tightened by the equalizer with device 16.

When the left skip is seated, the shutter of the left dosing bin opens and the shutter of the receiving raven of the dispenser is simultaneously switched, causing the left sleeve of the receiving funnel to overlap and coal from the left dosing bunker is poured into the left squit. Simultaneously, coal is loaded right dosing bunker.

With the return movement of the left okip, under the action of the counterweight, the shutter of the left dosing bin is closed.

Structurally, the closures of the metering bins are designed in such a way that, in the open position, the bolt 13 and the pan 1 form a chute, through which the coal from the metering bunker is sent directly to the phone in a skip, due to which coal consumption is completely excluded.

The sealing of the loading device is carried out by the closures of the dosing bins and the closure of the receiving hopper of the dispenser.

The upper walls 18 of the receiving funnel 5 have a hinged lock, which allows them to deviate in case of pieces of coal between the dispenser gate and the etiology of the shades.
