Abstract

The device relates to ferrous metallurgy, in particular to devices for feeding bulk materials into molds. The purpose of the invention is to increase the reliability of the device when dosing poorly flowing mafcj. materials, for example, metal chop. The device comprises a hopper 1, a chute 3, a chute 6, a dispenser 8 and a traverse. The bunker 1 is provided with a single-sloping bottom 4, the chute 6 is installed obliquely towards its lower part, and the dispenser 8 is designed as a plunger mounted on the chute, with the possibility of reciprocating movement. In addition, the dispenser 8 is kinematically connected to the crosshead 14 by means of levers with counterweights. Such an embodiment of the device allows the batch dosing of poorly flowing materials into the molds without the use of a special drive for the dispenser. 1 hp f-ly, 3 ill. UJ (L., -; Fig.Z

Description

tU

The invention relates to ferrous metallurgy, in particular, to devices for feeding bulk materials into molds.

The purpose of the invention is to improve the reliability of the device when dispensing poorly flowing materials, such as metal sech.

FIG. 1 shows the proposed device for feeding bulk material, general view; in fig. 2 view A in FIG. one; in fig. 3 shows a section BB in FIG. 2

When the device is lifted for further transportation, the traverse first moves with the counter-load levers all the way to the upper stop 15, moving the plunger to the extreme extended position. At the same time, the plunger pushes forward along the groove of the material pordia, which is equal in volume to the prod uct. The device contains a bunker I, which has a plunger cross-section area of 15

at the top of the inlet funnel 2, in the lower part of the chute 3 and inclined bottom 4. The vertical walls of the bunker end with the supports 5. On the outer side of the chute there is a chute 6 made of a flat sheet welded to the vertical walls. On the gutter is mounted with the ability to move in the direction of its course. After touching the shoes 17 with the upper stop 15, the entire device is detached from the platform and transported to the molds by a crane, where it 20 is placed on the mold above, so that the axis of the opening 19 approximately coincides with the vertical axis of the mold. When the traverse device is installed, the plunger 8 is lowered until the lever 7 is touched. The plunger through the rods 9, 25 counterweights with the bottom stop 16. When

The chassis 10 and the counter-load levers I1 are kinematically connected to the crosshead 12. The lever 10 and the counter-loads 11 are rigidly fixed on the axis 13 that is hingedly mounted on the body. The crossbar is hinged on the counter-loads and has an eye 14 for suspension on the hook of the lifting device.

On the case, there are upper 15 and lower 16 stops on the outside to restrict the movement of counter-load levers when they rotate around the axis 13. The counter-load levers interact with the upper stop through removable boot 17, which serves to adjust the plunger stroke by means of liners. To direct a portion of the material into the mold, there is a tray 18 under the chute.

The device works as follows.

in a way.

For loading, the device is placed with a crane on a horizontal platform. At the same time, the yoke 12, together with the counter-load levers 11, continues to move down to the stop into the lower stop 16 and then to the side. When lowering, the counter-load levers rotate the axis 13 with the lever 10 fixed on it, which through t g 9 acts on the plunger B, pulling it to the lowest position. Material is loaded through

With this, the plunger is drawn in and the vacant space on the channel is filled with a new portion of material from the hopper. In the course of the next traverse, upward JO a new piece of material advances along the chute and dumps the previous portion over the edge of the chute onto the tray 18, from where the material slides through the opening 19 inside the mold to the pallet. After touching the counter-load arms with the upper stops 15, the device is removed from the mold and transported to the next mold. During transport, the plunger is in the extended position. At the next mold, the cycle repeats.

The use of a plunger, kinematically connected with a cross-arm, for docking allows you to do without gauges and actuating gates, as well as without a drive for moving the plunger itself, which simplifies the design of the device, saves time and costs

Claims (1)

1. A device for feeding a free-flowing JC material predominantly to a mold, comprising a vertical-wall hopper, a chute, a chute, a dosing unit and a traverse, characterized in that receiving funnel and occupies a position on chute 6 at an angle of repose, not income to the edge of the chute over a distance approximately equal to the course of the plunger, When the device is lifted for further transportation, the traverse first moves with the counter-load levers all the way to the upper stop 15, moving the plunger to the extreme extended position. At the same time, the plunger pushes forward along the groove of the material pordia, equal in volume to the product of the area of the plunger section his move. After touching the shoes 17 with the upper support 15, the entire device comes off the platform and is transported to the molds by a crane, where it is placed on the mold above, so that the axis of the opening 19 approximately coincides with the vertical axis of the mold. When installing the device, the traverse is lowered until the arms of the cargo carriers touch the lower stop 16. When five 0 With this, the plunger is drawn in and the vacant space on the channel is filled with a new portion of material from the hopper. In the course of the next traverse, upward JO a new piece of material advances along the chute and dumps the previous portion over the edge of the chute onto the tray 18, from where the material slides through the opening 19 inside the mold to the pallet. After touching the counter-load arms with the upper stops 15, the device is removed from the mold and transported to the next mold. During transport, the plunger is in the extended position. At the next mold, the cycle repeats. The use of a plunger, kinematically connected with a cross-arm, for dozering, makes it possible to dispense with gauges and actuating gates, as well as without an actuator for moving the plunger itself, which simplifies the design of the device, saves time and costs Q for manufacturing and service. Invention Formula 1. A device for feeding the C material preferably into the molds, comprising a vertical-wall hopper, a chute, a chute, a metering device and a traverse, characterized in that, for the purpose of reliability of the device when dosing poorly flowing materials, for example, a metal slit, the bunker is equipped with a leaning bottom, the chute is mounted obliquely towards its lower part, and the dispenser is filled in the form of a plunger mounted on 1D52646 trough with the possibility of reciprocating movement. 2, the apparatus according to claim 1, characterized in that the plunger is provided with levers with counterweights and is kinematically connected with the crosshead.
