Description

The proposed machine for sinking, shafts is intended for the passage of shafts through the rocks that go to / Kyle, such as: clay, loess, vegetable earth, soft shales, etc. The machine consists of two metal drums, equipped with regulating teeth for soil and rotating during operation around a horizontal axis in bearings mounted in a frame, which in turn rotates around a vertical rod driven into the center of the shaft. The removed grab, which is grabbed by the cutting teeth, is poured onto a belt conveyor and fed to a bucket elevator, which lifts the ground and dumps it / through the sleeve into the substituted tubs. The car moves on wheels, and the front wheels can be lifted out with a special carriage.

In FIG. 1 is a side view of the machine; FIG. 2 is a view from above; FIG. 3 is a section along line AB in FIG. one; FIG. 4 is a top view of FIG. 3; FIG. 5- vertical section of the machine; Fig, b is a top view of a device for raising and lowering the front drive wheel; FIG. 7-side elevator view.

The machine (Figs. 1 and 2) consists of two interconnected frames of 7 rectangular sections, voidable of ko (33). f

digging iron. The small frame serves as the basis for the second part of the elevator; In a large frame, two metal drums 2 are placed on the bearings. A series of gear wheels 3 for the Gaul chains 3 connecting the respective pairs of wheels on both drum are mounted on these drums. On each pair of wheels, cutting teeth are reinforced, which, while rotating, produce cutting and lifting of the soil (Fig. 3).

The shape of the teeth is provided so that provides the least resistance of the undercut mass.

The whole frame rests on the four wheels 4, 5 arranged in such a way that their axes intersect at one point. At this point, the ear 27 is fixed, which is put on the iron rod, which serves as the axis of rotation of the entire system.

The two rear wheels 4 are fixed to the frame without movement, and the two front 5 can move in a vertical plane. This vertical movement can occur due to the fact that the axis of the left wheel 5 is mounted on a special carriage that can be raised and lowered, since the skid 6 connected to it can move in parallel 7. The carriage can be moved up and down by turning the flywheel 8, which , screwing in or unscrewing the screw, presses the runner and thereby forces it together with the carriage to make this or that motion.

The other wheel (right) has a slightly more complicated construction. It is also mounted on a special carriage, but, in addition, there is a gear 9 on the wheel (Fig. 4) connected to a bevel gear JO. The latter sits on the long axis 7 / mounted on the gear gear J3 (FIGS. 3, 4 and 5). The connection of this axis with the gear is free, BUT in the gear there is a key that can freely move along the long groove J2. Such a connection allows the carriage to be raised and lowered, since the axis of the bevel gear JO is not fixedly connected with the gear J3, but then the rotation of the gear JO will be transmitted by gear 13, in whatever position it is with the carriage. This carriage, like the first one, has a skid 14 in the form of a trough, which runs parallel to x / 5 and can also freely, using the handwheel 76 and screw / 7, raise and lower (Fig. 2,3, 5 vt 6).

Two corners 18 (Figs. 1, 2, 3) are fixed on top of the frame and the pipes described, on which gear 13 is fixed with the help of a bearing, not having rotation, thanks to a bracket / 9, no movement. The shaft / 7 passes into the gear wheel, with which it is not tightly connected, as the key can walk along the long groove / 2.

Gear / 3 coupled with bevel gear 20, and the latter, using a common shaft 27, -with gear 22, assigned to the Gall chain (Fig. 2, 5, 6).

The two drums 2 inserted into the frame are reinforced in it by means of two bearings 22c. At the right bearing on the shaft of the upper tube there is a gear 25 for the chain Gall.

At the back of the drums, a belt conveyor is mounted on the same frame, the tape of which is mounted on the wooden rollers 24 and can be moved thanks to the following mechanism. One of the rollers 25 is driving and receives movement from gears 26. Gear 29 is connected by a Gall circuit to the drive shaft J. of the machine (Fig. 1, 2).

 The movement of the first part is carried out as follows. Suppose that our frame is placed on the surface, and that through an ear 27 is hammered into the ground an iron rod with a length of / 4 arsh. Let the leading axis 30 get rotated in some way, then both drums 2 connected by Gall chains also get rotated, and the teeth attached to them start moving (Figs. 2 and 3).

Both front wheels can be lowered in such a way that the ends of the teeth will cut off the surface of the earth and drop it onto the conveyor; the latter, due to the fact that it is connected with the help of gears and a Gall chain with a drive shaft, will also be set in motion and will carry the cut off earth and drop it from the left side. In order for the teeth to continue to cut the ground, the whole frame must be moved in some way, and then each tooth will cut off new strips of earth.

The movement of this frame is carried out with the help of a motor apparatus consisting of a motor 37 (Fig. 2) connected to a worm gear in a common box 32. On each side, the worm wheel has a gear 33 and 34 on each side. gear 23, and therefore the rotation of the motor is transmitted to the drive shaft 5L. The same gear 34 is connected by a chain Gaul to gear 55, and therefore the rotation of the motor through the chain Gaul, gears 20, 73, vertical shaft // and gears 70 and 9 is transmitted to wheel 5 / equipped with spurs 36 (Fig. 2 5, 6). When the Motopa rotates, therefore, the gear wheel rotates and, thanks to the pillars slamming into the soil, the whole system moves forward.

But, since the frame has a fixed point 27 in the form of a rod driven into the ground, the movement of the entire system can occur only around the circumference, and the teeth will all the time cut off the ground and drop it on the conveyor, which causes the deepening of the circular shaft with each turn of the system.

The multi-bucket elevator (fig. 7) consists of a frame-37, made of angular iron. On this frame reinforced frame 3S of the same iron.

A gear 40 is attached to the shaft in common with the gear 39 and coupled to the bevel gear 47, which has a shaft lying in the bearings 42, located on the transverse beams - channels fixed to the channel system.

On the shaft 43, which is the drive shaft, there is a movable Coupling 44 (Fig. 1), with its key in the slot; this clutch, using bolts, connects to the clutch located on the drive shaft of the upper drum. In the upper part on the frame there is a second elevator wheel, the bearings of which lie on the channels. At the elevator wheels, the Nuts of the Gall chain with buckets are shaped so that the bulk body does not crumble at the beginning of the tilting, but is itself braked using the extended edge 45. On the side of the elevator, on the bracket, the detachable hose 46 is reinforced, which thanks to the notch in its coupling 47 and pin 48 can be easily disengaged. All the soil that is poured out of the buckets must fall into the hole in the hose, from where it enters the substituted bucket. To prevent the earth from crumbling, the elevator wheel is covered by a casing not shown in the drawing.

To install the combine in the center of the intended mine is driven into the depth of / 4 arsh. a metal rod, on which the frame's ear 27 is placed, and the frame itself, together with the drums 2, is lowered onto the ground, resting against it with its four wheels. Screws 77 must be screwed in to the full; in this position, the edge of the teeth does not touch the ground.

Then, an elevator is put on the small frame and fastened to the frame with latches or bolts (not indicated on the drawing). The elevator is connected to the drive shaft 30 by means of a movable coupling 44 (FIG. 1). Next, a assembled unit consisting of a worm gear motor is mounted on a special place, located above the reels 2, and the gears 33 and 34 are connected by means of Gall chains to the gear 23, the motion transmitting drive shaft 30, and the gear wheel 55, thanks to which the whole machine will have a forward movement.,

When the machine is assembled, current is allowed (all electrical connections are not shown in the drawings); the motor starts to work, the worm gear drives both drums to rotate; along with it, the teeth, which by their edges do not reach the ground, begin to move; with the help of another gear 35, the whole machine receives a forward movement.

The elevator, being connected to the shaft, also comes into motion. The motion of the entire system, due to one fixed point, will be rotational.

The next moment, the screws / 7 (Fig. 3) are unscrewed, due to which the teeth begin to cut off the soil with their ends and drop it onto the conveyor, and transfer the last to the left, where the cut weight will be picked up by the elevator buckets. Buckets filled with earth are raised up and there it is dropped into the hose.

This work is very laborious, takes a lot of hands, especially at large mines, and yet is very slow. Therefore, it is highly advisable to have the proposed machine for passing the mines, because its transportation costs nothing, but a gain in time and cost is obtained. Each machine can easily handle penetrations of different diameters, for which only minor rework is required.

The subject matter of the invention.
