Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called drum cutter mining machine comprising a machine body carrying a floating arm. The swing arm is pivotable with respect to the machine body under the support of the multi-lateral ram. The floating arm also carries a mineral cutting tip rotatable about an axis that in turn extends transversely to the longitudinal axis of the machine body. Basically, such mining machines are either single-ended, with a floating arm at one end, or double-ended, with floating arms at both ends. These can then be conveyor-equipped (usually for media into thick mineral formations) or unequipped.
It may also be of the "white band" type (usually for media to thin mineral layers). However, for both types, guidance of the mining machine is accomplished by heli contact with an armored scraper chain conveyor that extends across the mineral surface.

Power for the conveying and cutting tips of both machines is conventionally provided through a suitable transmission gearbox containing a speed reduction/variable gear wheel housed within the gearhead tip to which the free arm is pivotally mounted. from at least one electric motor mounted within the machine body. If the mining machine is double-ended with one electric motor, there is also a need to provide a consistent shaft for transmitting power to the transmission tip remote from the electric motor. Conventionally, the axis of rotation of the electric motor is parallel to the longitudinal axis of the machine body, so it is necessary to transmit the drive through 90°, making a particular desire for complex helical gear sets that are expensive from a manufacturing and maintenance point of view. arises from this. Furthermore, conventional machine bodies were assembled from several sections connected vertically with bolts. and ] 4 For the connections between adjoining compartments, sections have often been provided that are susceptible to imperfect mechanical manipulation. Therefore, reducing the number of connections will reduce the number of problems along the way.

According to the invention, a machine body reinforced with a separate device containing an electronic device accommodating a machine lateral and a device for monitoring the health of the machine; an electromechanical device and at least one floating arm pivotally connected to the electromechanical device about one of the laterally extending shafts of the machine body and carrying a rotatable cutting tip remote from the machine body; the electromechanical device for powering at least the engaged cutting tip via a transmission transmission and optionally for powering a mechanical conveying device σ via a transmission transmission; 1. An iron ore machine is provided, which is characterized in that it contains at least one electric motor with a rotational capacity of nJ for the horizontal axis 1111.

Thus, for a single-ended mining machine, one electromechanical device is gripped at one end of the electronics device. However, for double-ended mining machines, the electronics have identical electromechanical devices gripped at their opposite ends. That is, the mining machine according to the invention incorporates only one connection between adjacent devices in its single-ended configuration, and only two connections between adjacent devices in its double-ended configuration. λ
1 only part of it is incorporated.

The mechanical conveying device may be powered by a cutting tip electric motor by means of a suitable power transmission, or the or each electromechanical device may be powered by an individual electric motor rotatable about parallel laterals, 1 one for the cutting tip and one for the mechanical conveyor, preferably with V'.
III machines may be included in a common electromechanical device,
Alternatively, the machine transport motor may be included within the transport compartment. The transport compartment may then form part of an electromechanical device. The cutting tip electric motor 1) may also be contained within a transmission tip, forming part of an electromechanical device and attached to a mechanical transport device. The or each cutting tip motor may or may not be coincident with the pivot axis of the engaged swing arm. Depending on the size of the mining machine (e.g. whether it is single-ended or four-ended or double-ended), the mining machine may have a single-mechanical carrier or a pair of spaced ('<f, and may have a mechanical transport device installed.

In addition, the mechanical transport device may include a transmission speed reducer and a transport power sprocket that can be engaged with a chain, or alternatively a rack when operated by so-called "chainless" technology. and, on the one hand, the transmission reduction device may be mechanical or electrical. The mechanical carrier may include an output sprocket rotatable about a transverse axis parallel to the motor axis.

Preferably, the mechanical transport device contains a speed reduction device. In particular, such a speed reducer may include a cutting tip or a root conveyor'1 (a planetary gear train and/or an internal zykroid forming part of the transmission reducer from the electric motor to the output sprocket). A gear arrangement may be included, however, on the one hand, the connection between the electric motor and the transmission reduction gear is conveniently opened by an electromechanical clutch.

It can easily be provided that the cutting tip motor is removably clasped into a mechanical device or to an electromechanical device. This in turn facilitates motor replacement for maintenance/defect correction purposes. Thus,
The end of the electromechanical device may be forked and may have a gripper that can be squeezed across the fork arm.

A first stage speed reduction value for the or each cutting tip is achieved by planetary deceleration of the output shaft of the cutting tip motor. As is common practice, further deceleration, if desired, can be achieved by means of a geared transmission reduction device extending along the idler arm towards the cutting tip. Additionally, if desired, a final stage speed reduction can be provided by a planetary float stage within the cutting tip. The desired speed, for example 20 revolutions/min, can then be achieved.
