The invention relates to the mining industry, namely to feeders for loading bulk or bulk material of certain fractions.

The purpose of the invention is to increase work efficiency by reducing the loss of overloaded material.

Figure 1 shows the feeder, a longitudinal section; figure 2 - node I in figure 1, fig.Z - node II in figure 1; figure 4 - view And fig.Z.

The feeder contains a frame with the guide chute 2, a table 3 mounted on the frame 1 with the possibility of reciprocating movement on the rollers A under the influence of the drive 5. Guides 6 are rigidly attached to the table 3, driving the tray 7. On the side walls of the chute 2, additional guides 8 with grooves 9 are immovably fixed on the bottom surface, opposite the slots 10, made on the upper surface of the main directions to the cix 6. Tray 7 is equipped with at least two latches 11 alternately locking the tray 7 then sec apravl yuschimi 6, the additional guide 8 by entering retainers into grooves 9 or 10, wherein the tray 7 is located on the same level with table 3.

The feeder is provided with a Table travel control, which is a strip .12 fixed to the bottom surface of table 3, with a series of through holes 13 (at least three) into which two adjustable stops are inserted. 14 interacting with the lever 15 of the control valve 16 mounted on the frame 1.

The feeder works as follows.

Table 3 performs a reciprocating motion.

During the forward movement, the movable table 3 moves along the rollers 4 towards the unloading side and moves the rock mass to the same side. During the return stroke, table 3 leaves the layer of material, a certain portion of which is poured into the haulage means 17. After this, the cycle is repeated. At the same time, the mass of the hearth is continuously and evenly poured into the loading haulage tool 17.

When an oversized piece appears on the table 3, it becomes necessary to move the tray 7 to the discharge edge of the table 3 to receive oversize on it. This is done as follows. From the control panel of the swinging feeder, the driver remotely connects tray 7 with the help of clamps 11 to the additional guides 8, simultaneously disconnecting it from the guides 6.

5 3 back with the help of clips 11, the tray 7 is connected to the guides 6, it is displaced to the edge of the table 3 by the amount of stroke. Permutation operations are repeated until the tray

7 will not take the desired position relative to the foot 3. Change the distance between the inter-, adjustable, stops 14, the size of the table 3 stroke and the amount of shift of the tray 7 are adjusted.

When the distance between the tray 7 and the discharge edge of the table 3 is less than the minimum size of the oversized piece, the tray 7 is fixed by means of latches {with table 3.

The oversized piece enters the tray 7 and due to the continuous movement of the rock mass in the direction of separation. loads during reciprocating 5 moving table 3 is separated from the total flow by a heap of mass not falling into the haulage means 17. After separation of the oversized piece from J of the total mountain flow MacQii tray 7 with the oversized piece takes the forward position, while tray 7 remains stationary when the table 3 moves backwards and moves with the table as it moves forward.

When the next oversized piece appears, the cycle repeats.

A new oversized piece pushes the first piece from tray 7 onto the screens 18 and as the latter moves to the front position, it rolls down the inclined screens 19 into the explosion chamber 20.

Claims (2)

1 The invention relates to mining and quarrying, in particular to feeders for loading a lump or sy bundle of material of certain fractions. The purpose of the invention is to increase work efficiency by reducing the loss of overloaded material. Figure 1 shows the feeder, a longitudinal section; figure 2 - node I in figure 1, fig.Z - node II in figure 1; figure 4 - view And fig.Z. The feeder contains a frame with guiding chute 2, table 3 mounted on frame 1 with the possibility of reciprocating movement on rollers A under the influence of water 5. Guides 6 are rigidly attached to table 3, causing the movement of tray 7. On the side walls of the groove 2, full-length guides 8 with grooves 9 are still immobile. They are located on the bottom surface opposite grooves 10 that are made on the upper surface of the main directions to chix 6. Tray 7 is equipped with at least two fixtures 11 that alternately fix the tray 7 either with guides 6, then with additional guides 8 by inserting clamps into grooves 9 or 10, while the tray 7 is flush with the table 3. The feeder is equipped with a Table Stroke adjuster, which is a bar .12 attached to the bottom the surface of the table 3, with a series of through holes 13 (at least three), into which two adjustable stops are inserted. 14, interacting with the control valve lever 15, mounted on frame 1. The feeder operates as follows. After switching on the drive 5, the movable table 3 makes a reciprocal post movement. During the forward movement, the movable table 3 moves along the rollers 4 in the direction of unloading and moves the rock mass in the same direction. When backing up, table 3 leaves the layer of material, a certain portion of which is poured into rollback means 17. After this, the cycle repeats. At the same time, the mountain mass is continuously and evenly dropped into loadable rollback means 17. 1 When an oversized 3 piece there is a need to move the tray 7 to the discharge edge of the table 3 for receiving oversize on it. This is done as follows. From the control panel of the swinging feeder, the driver remotely connects tray 7 using clamps 11 with additional guides 8, simultaneously disconnecting it with guides 6. . When the table 3 moves backward with the help of clips 11, the tray 7 is connected to the guides 6, it is displaced to the edge of the table 3 by the amount of stroke. The shuffling operations are repeated until the tray 7 takes the desired position relative to the foot 3. Change the distance between the interchangeable, adjustable stops 14, adjust the amount of movement of the table 3 and the offset of the tray 7. When the distance between the tray 7 and the discharge edge is reached Table 3 is smaller than the minimum size of an oversized piece. Tray 7 is fixed by means of clamps {with table 3. The oversized piece falls on tray 7 and due to the continuous movement of the rock mass towards the unloading side during reciprocating movement After separation of the oversized piece from the total mountain stream, MacQii Tray 7 with the oversized piece takes the front position, while Tray 7 remains stationary when the table travels 3 backwards and moves together. with the table as you move it forward. When the next oversized piece appears, the cycle repeats. A new oversized piece pushes the first piece from tray 7 onto the screens 18 and, when the latter moves to the forward position, it rolls down the inclined screens 19 into the blast chamber 20. Invention I. The feeder containing the frame guiding the chute table mounted on the frame with the possibility of returnable movement from the drive, and a tray mounted in guides, characterized in that, in order to increase the working efficiency by reducing losses of the material being handled, it is provided with rigidly and symmetrically fixed on the side walls of the gutter with additional guides with grooves on their lower surface, at least two tray locking elements and a table motion control, CBHSiaHHbiM with the drive control element of the latter, the first guides being rigidly fixed on the table and made grooves on their upper surface, and each of the locking elements is mounted on the corresponding end of the tray with the possibility of entering into the corresponding grooves of the guides, and the tray is placed with the location of its level the eyes of the surface is not higher than the level of the working poverzsnosti table. 2. The feeder of claim 1, wherein the table travel regulator contains a bar with a series of through holes fixed on the bottom surface of the table and installed into the corresponding holes with the possibility of interacting with the control element driven by the movement of the table, placed on the frame, two fingers.
