Description

Gearbox portable rotation mining combine

The technical field to which the utility model

 The invention relates to mining equipment, in particular to the mechanisms of mining combines.

The level of technology

From the prior art a large number of designs of mining combines.

As the closest analogue of the selected mining combine, containing a portable rotation gearbox (RU 2319835, Е21С 27/00, publication date 03/20/2008). The disadvantage of this known construction is unreliable disconnection of the portable rotation.

The essence of the utility model

The problem solved by the present utility model is to create a mechanism of portable rotation, ensuring efficient and reliable operation.

In the course of solving this technical problem, an expansion of the arsenal of designs of portable rotation gearboxes with reliable drive disconnection is provided.

This technical result is achieved by the fact that the reducer of the portable rotation of a mining combine comprises a housing and a kinematic chain inside it, including an output link mounted on a shaft, in said housing there is an opening in which a rod is connected to said shaft inside said housing, the shaft is made with the possibility of opening the kinematic connection with the said output link by moving it along the axis of its rotation.

This technical result is also achieved by the fact that a sleeve is installed in said hole in the housing, through which said rod passes, while the rod itself is made of metal in the form of a screw

A distinctive feature of the utility model is the ability to kinematically disable the output link of the gearbox by moving the shaft on which it is installed.

Implementation of the utility model

One of the most effective rock destruction schemes is the scheme with planetary kinematics of cutting tools.

The implementation of planetary kinematics of rock destruction requires the use of several mechanisms (drives, gearboxes, gears, etc.) for each component of the movement of the cutting tool. In turn, each of these mechanisms must be equipped with reliable means of opening the kinematic chain to quickly stop the executive bodies.

The mining combine contains the first and second executive bodies, as shown in FIG. 2. Each of the Executive bodies contains the actuator 4, the gear 3, the transfer gear 2 and the cutting tool 1. Cutting tool 1 (for example, a disk cutter) is connected to the drive 4 through the gear 3 and the transfer gear 2.

The gearbox housings 3 of the executive bodies are connected by their side walls to the gearbox housing 5 of the portable rotation, on the back wall of which the engine 6 of the portable rotation is mounted.

Gearboxes 3 executive bodies can be made with spur gears.

The gearbox 5 of the portable rotation of a mining combine comprises a housing and a kinematic chain 7 inside it, as shown in FIG. 3 and FIG. 4. The kinematic chain 7 includes an output link 11 mounted on the shaft 10. Usually the output link is a gear wheel.

In the above-mentioned case there is a hole in which a rod 9 is installed, connected to said shaft 10. Shaft 10 is installed with the possibility of opening a kinematic connection with said output link 11 by moving it along its axis of rotation. The rod 9 is connected to the drive of the reciprocating motion, for example, a hydraulic cylinder (not shown).

In the hole of the gear housing can be installed sleeve 8, through which the rod 9, while the rod 9 can be made of metal in the form of a screw.

The harvester may contain additional cutting tools: upper and lower breaker device, berm milling cutters, rammers, etc.

The combine works as follows.

Combine moves and moves to the bottom of the chassis. The gearbox 5 portable rotation provides a slow rotation of the transfer gears 2 and the cutting tool 1. The gear 3 actuator through the handle of the transfer gears 2 inform the cutting tool 1 cutting movement. At their presence, the upper breaker device forms the roof of the excavation, the berm body forms the walls and soil of the excavation. Cutting tool 1 of the executive body, making complex movements, process the face area. Destroyed rock mass is then loaded, for example, on a central scraper conveyor (not shown) and then unloaded onto vehicles installed behind the combine.

If it is necessary to drive the combine away from the bottomhole, the synchronization mechanism is opened and the arms of the executive bodies are reduced to a position in which the cutting tool will not cling to the walls of the mine as the combine moves from the bottom.

If necessary, quickly stop the portable movement of the actuator, the rod 9 moves in the hole of the gear housing 5 and moves the shaft 10 along its axis. As a result of the movement of the shaft 10, its kinematic connection with the output link 11 is opened and the movement from the engine 6 is not transmitted. Thus, the utility model provides a fast and reliable shutdown drive portable movement.
