Description

The proposed self-propelled shovel, designed primarily for loading, the rocks in horizontal workings, has, similarly to known devices of this kind, a crawler course and conveyors driven by electric motors.

A distinctive feature of this self-propelled shovel is the fact that the shovel for loading rock onto a conveyor belt has the ability to make vertical movements, while remaining parallel to the plane of the sub-basement.

In FIG. 1 shows a side view of a self-propelled shovel in horizontal development during operation; FIG. 2 - the same in the plan; FIG. 3 is a front view of the maschine; FIG. 4 is a vertical cross-sectional view of the entire device.

The scooping unit of the assembly constituting the self-propelled shovel is an open front bucket (fig. 1, 2, 4). outlined in its shape scoop. This carpet is rigidly fixed on a circular bar 2, passing through a longitudinal channel in the rail. 3. The rod may rotate in the rail, but is kept from the longitudinal movement by the ring 4. The protruding end of the rod is divided into a square.

At the free end of the rail in special ears, a stop bracket 5 is fixed, which prevents rotation of the rod in the rail. The staple is held in the closed position by means of a spring 6. The rail 5 enters the swing frame where all the mechanisms are located.

At the front of the pivot frame is the driver's cabin, where the car seat is located, in front of which the controllers are located (reversors) and the levers of engagement of 7 coupling couplings. A tracked drive with a platform, along which the lower platform of the swing frame rolls on runners, is used to move the maschine along the mine.

The breed from the bucket is transferred to a belt conveyor 8 rigidly mounted on a track frame. In this conveyor, the drive station is carried out by a motor roller 9 in which the motor and the entire conveyor gearbox are mounted.

The bucket motion reducer and the steer reduction gear are driven by the engine 10 by means of couplings 11 and 12, controlled by the interlocking lever 13.

Self-propelled shovel works as follows. Moving the spade on the caterpillar to the destroyed rock, the driver, including the // coupling, feeds forward the rail 2, and with it the bucket. Injected into the rock, the bucket is filled. A lift mechanism is then activated, operating as follows. A screw 14 with a rectangular thread is rigidly fixed in the lower platform (rotary). This screw 14 passes through the profiled nut 15, which is fixed in the upper platform by means of an overlay ring 16 in such a way that it can rotate relative to it, but is devoid of relative axial movement. A worm gear 17 is mounted on this nut. Thus, as the lifting mechanism rotates, the nut 15 begins to rotate and, moving the screw up or down, pulls the upper platform beyond its own. Guidelines 18 are used to eliminate distortions and facilitate screw operation.

When lifting the entire pivoting frame, the bucket /, loaded with rock, is also raised. Thereafter, the motor 10 is reversed and the rail 3 begins to enter inside the pivot frame. Moving to the right (according to the diagram), the rail reaches the reflector 20, rigidly fixed on the frame. The reflector, pressing the upper arm of the stop bracket, deforms the spring 6 and releases the rod 2, but before the reflector began to act on the stop bracket, the square end of the rod 2 divided into a square begins to enter the corresponding hole of the last gear wheel 21 of the rotation gearbox.

Thus, the rod 3, released from the stop bracket 5, is connected to the pivoting gearbox.

In this position of the rod, the ladle is adjacent to the receiving hopper 19 of the conveyor (Fig. 2).

By turning the handle 7, the driver switches on the rotation gearing through the clutch 12, simultaneously opening the clutch 11. At the same time, the driver turns on the drive roller 9 of the conveyor. The rotation reduction gear, rotating the rod 2, deflates the bucket onto the conveyor 8, from where the rock is reloaded onto the conveyor line 22 (Fig. 1) running along the whole of the excavation.

After emptying, the bucket comes back to its original position due to the reverse of the rotation reduction gear and, when the clutch is turned on, // moves again forward. When the rail is moving to the left (Fig. 4), the stop bracket 5 comes out from under the reflector 20 and locks the rod 3 under the influence of the spring, preventing it from turning.

The work of the gearbox of the movement of the shovel and the gearbox of the turn must be blocked mechanically and electrically, since the stroke of the rail and the turn of the shaft must be performed within strictly specified limits. After each stroke of the rail, the pivoting frame rotates at a certain angle - this way the entire width of the excavation is serviced. The mechanism for moving the tracks and turning the pivot frame relative to the goose frame; -P1 may be the same as that used in tracked excavators and is not shown in the drawing.

The subject matter of the invention.

Self-propelled shovel for loading rock in horizontal workings

using a conveyor to remove the rock, characterized in that, in order to load the rock onto the conveyor belt, its carpet is capable of vertical movement while maintaining the position; parallel to the plane of the basal base.
