Description

1 Mobile Crusher The invention relates to a mobile crusher plant for lumpy material, including a frame equipped with at least one 5 travelling mechanism, a crusher arranged on the frame and having a discharge opening for crushed material, a charging conveyor device mounted on the frame for charging the crusher, and a dumping conveyor device whose feeding side end is located below the discharge opening of the crusher. 10 The material extracted in mining by various extraction machines and extraction methods is generally extremely inhomogenous as regards the rock sizes, with huge boulders being, in particular, frequently encountered in the broken material, which are not 15 suitable for transportation on conveyor belts. It is, therefore, necessary in most cases to employ crushing means, which reduce lumpy crushing material such as ores (iron ore, brown iron ore, copper ore, gold ore), rocks (granite, rock lumps, gypsum rock, serpentine rock, limestone), hard coal, oil shale, marl, clay 20 and mining waste to the desired, predetermined maximum grain size. It is known to use mobile crusher plants, which are loaded directly on the mining site by the excavation equipment, e.g. 25 shovel dredgers, following the progression of extraction. Such crushing devices can be designed as continuous crushers, with continuous conveyors and, in particular, steel plate conveyors being usually employed for charging the same. The steel plate conveyors will subsequently transport the material to be reduced 30 in size into the range of action of crusher or impact rolls, wherein configurations in which a plurality of such crusher or impact rolls are put into effect one after the other in the conveying direction are known for such crushing plants. The mobile crusher plant further comprises an integrated discharge 2 conveyor, which is usually configured as a conveyor belt and allows material crushed by the crusher to be transferred to a separate, stationary conveyor. Mobile crusher plants are known in various configurations. From AT-B 388 968, a mobile crushing plant is known, in which the material to be crushed is fed to a charging container and transferred to a consecutively arranged dumping conveyor device via an interposed crushing device. The temporarily supported 0 charging container and the consecutively arranged dumping conveyor device are configured in a manner cantilevering relative to the crawler mechanism. The consecutively arranged dumping conveyor device is articulately arranged on a cantilevering frame part of the crushing plant below the surge 5 hopper. Due to the cantilevering arrangement of the charging container and the dumping conveyor device, particularly during loading of the charging container, a non-negligible vibratory motion not only of the feeding side end but, in particular, also of the dumping conveyor device will result on account of the 0 high weight of the material to be crushed, thus affecting haulage as well as the service lives of the overall machines and various machine parts. As a result, a number of measures have already been proposed to avoid such vibration stresses. In DE-36 08 789 Al, a temporary support for the charging container is, 5 for instance, described. The transport mechanism in that case is formed by a variable-height crawler mechanism provided with a lifting table. In the device according to DE 10 2006 059 876 Al, it is provided that the cantilevering charging container is associated with a lowerable pendulum support that can be adapted 0 to potential surface irregularities of the formation level, so that the impact pulse will be absorbed directly below the container.
3 From DE 10 2007 039 7 66 Al, a charging container has become known, which is rigidly fixed to a supporting structure formed by the crawler mechanism and a frame. From WO 99/54049, a mode of construction of a mobile crusher has become known, in which the frame rests on the floor together with the charging container during the haulage operation. For the travelling operation, the frame is lifted by the aid of a liftable and lowerable crawler mechanism. Also in WO 2008/032057 A2, a separate support for the charging container is provided in order to avoid vibrations caused by the impact pulse of the overall device. In the prior art, more or less complex support structures are thus usually provided for the charging side end of the mobile crusher plant to take up the impact pulse during loading of the charging container. It is against this background and the problems and difficulties associated therewith that the present invention has been developed. Certain objects and advantages of the present invention will become apparent from the following description, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed. The present invention aims to configure a mobile crusher plant in a manner that complex support structures can be obviated, wherein the cantilevering dumping conveyor device is to be kept free from vibrations stresses nevertheless. According to a first aspect of the present invention, there is provided a mobile crusher plant for lumpy material, including a frame equipped with at least one travelling mechanism, a crusher arranged on the frame (and having a discharge opening for crushed material, a charging conveyor device mounted on the frame for charging the crusher, and a dumping 3a conveyor device whose feeding side end is located below the discharge opening of the crusher, wherein the dumping conveyor device, decoupled from the crusher, is designed as a separately movable unit provided with its own travelling mechanism, whose charging side end is provided below the discharge opening of the crusher.In that the dumping conveyor device is not mounted on the same frame as the charging conveyor device and the crusher, possible vibrations occurring during the charging of lumpy materials onto the charging conveyor device will not be transmitted to the dumping conveyor device. There is consequently no rigid connection between the charging conveyor device and the crusher, on the one hand, and the dumping conveyor device, on the other hand, such that the charging side end of the dumping conveyor device will only be stressed by the 4 impact of the crushed material falling from the discharging opening of the crusher. This stress is, however, substantially more uniform than the dynamic stress caused by the impact pulses of the not yet crushed, lumpy material such that the dumping conveyor device will substantially not be subjected to vibration stresses. Due to the fact that the dumping conveyor device is provided with its own travelling mechanism, a substantially more flexible use of the dumping conveyor device will be enabled. The dumping conveyor device can, in particular, be arranged in 0 different positions and orientations relative to the crusher so as to readily enable the haulage of the crushed material in a region laterally beyond the excavated road. Furthermore, almost any desired dumping conveyor means can be employed, with the only prerequisite being that the charging-side end of the 5 dumping conveyor device be positionable below the discharge opening of the crusher. As is known per se, the charging side end of the charging conveyor device preferably comprises a charging container, in 0 particular a hopper. To take up the impact pulses occurring during loading of the charging conveyor device and, in particular, the charging container, it is provided according to a preferred further development that at least one travelling mechanism is fixed to the charging side end region of the frame. 5 The charging side end region of the frame in this case is the frame region that is located adjacent the charging end of the charging conveyor device. The configuration in this case is devised such that the travelling mechanism fixed to the charging side end region of the frame is arranged below the charging W0 container. In order to ensure sufficient stability of the device, it is provided according to a further preferred configuration that at 5 least one further travelling mechanism is fixed to the crusher side end region of the frame. The optimum support will be achieved according to a preferred further development, if the travelling mechanisms comprise three bearings for the frame, which span a triangle. In this context, it may advantageously be provided that the travelling mechanism fixed to the charging side end region of the frame each comprises a bearing on both sides outside the projection of the 0 charging conveyor device, and the travelling mechanism fixed to the crusher side end region of the frame comprises a central bearing. In this manner, a supporting triangle is formed so as to ensure an accordingly stable support. 5 In order to account for possible unevennesses of the floor of the excavation road, it is provided according to a preferred further development that the travelling mechanisms are each connected to the frame so as to be pivotable about a pendulum pivot extending horizontally and transversely to the conveying 0 direction. As known per se, the charging conveyor device may preferably be comprised of a conveyor belt, in particular a steel plate conveyor. 5 The mobility is preferably achieved in that the travelling mechanism(s) of the crusher and/or the travelling mechanism of the dumping conveyor device is/are configured as crawler mechanism(s). Alternatively, the travelling mechanism may also 0 be designed to comprise walking legs. Due to the configuration of the dumping conveyor device as a separate unit, substantially any desired dumping conveyor devices can be employed, the dumping conveyor device preferably 6 comprising at least one, preferably two, discharge conveyors cantilevering from a movable frame. In a further preferred configuration, the dumping conveyor device can be designed as a bridge conveyor and, in particular, a bridge belt conveyor. Compared to the embodiment comprising two discharge conveyors cantilevering from a movable frame, an essential technical simplification of the further transport of the material is thereby be provided, since the charging side and 0 discharging side ends of the consecutive conveyor are mounted on the end points and can thus be adapted to changes in terrain. In order to enable the pivoting movement of the discharge conveyor and, in particular, the adjustment of the conveying 5 direction, it is preferably provided that the conveying means of the dumping conveyor are arranged to be pivotable about a vertical axis of rotation relative to the travelling mechanism of the dumping conveyor. o In the main, the unit comprising the crusher and the charging conveyor device can be designed in a particularly low-structured manner, it merely having to be ensured that the charging side end of the dumping conveyor, decoupled from the crusher, is arranged below a cantilevering frame part carrying the crusher. 5 In the following, the invention will be explained in more detail by way of exemplary embodiments schematically illustrated in the drawing. Therein, Fig. 1 is a side view of the crusher plant according to the invention; Fig. 2 is a top view of the crusher 0 plant according to the invention including an excavation apparatus in the delivery position; Fig. 3 is a side view of the charging conveyor device together with the crusher; Fig. 4 is a top view of the charging conveyor device, Fig. 5 is a partially sectioned front view of the charging device; Fig. 6 depicts a 7 modified configuration in which the dumping conveyor device is designed as a bridge belt conveyor; and Figs. 7a, b, c are side views of the bridge conveyor in different positions. Fig. 1 depicts a crusher plant 1 according to the present invention, said crusher plant 1 comprising a charging conveyor device 2 and a dumping conveyor device 3. The charging conveyor device 2 on its charging side end carries a charging container in the form of a hopper 4, into which the excavated material is 0 filled by the excavation apparatus. The material present in the hopper 4 is fed by a steel plate conveyor 5 to the crusher 6, where the material is crushed and subsequently transferred to the charging side end 7 of the dumping conveyor device 3. The dumping conveyor device 3 comprises two cantilevering, 5 substantially horizontally pivotable arms 8 and 9, via which the charging and discharging points of the material conveyed by the conveying device can be flexibly selected by displacing the dumping conveyor device 3 by the aid of the crawler mechanism 10. 0 From Fig. 2, it is apparent that the charging conveyor device 2 with the hopper 4 is positioned in the vicinity of an excavation apparatus 11, and the arm 8 of the dumping conveyor device 3 is arranged below the dumping end of the charging conveyor device 5 2, in particularly below the crusher 6. The excavated material is thus transported from the hopper 4 via the steel plate conveyor 5 through the crusher 6, and via the arms 8 and 9 of the dumping conveyor device to a stationary discharge conveying means, which is only schematically illustrated and denoted by 30 12. In Fig. 3, it is to be seen that at the charging conveyor device 2, below the hopper 4, a crawler mechanism 21 is arranged, which is able to optimally take up the forces occurring during 8 charging of the charging conveyor device, so that vibrations caused by the impact pulse will be largely avoided there. The conveying means 5 in this case is configured as a steel plate conveyor whose dumping end 13 is provided above the crusher 6. After the material has passed the crusher 6, it is transferred to the charging end 7 of the cantilevering arm 8 of the dumping conveyor device 3 and further transported. In doing so, it is essential that no firm connection, or no connection at all, be provided between the crusher 6, or a consecutively arranged 0 discharging funnel 17, and the cantilevering arm 8 of the dumping conveyor device 3, so that no vibrations will be transmitted to the dumping conveyor device 3 by the cantilever of a discharging belt provided on the frame. The material leaving the crusher 6 through the discharging funnel 17 5 generally comprises a homogenous grain size such that no dynamic forces will basically occur at the charging end 7 of the cantilevering arm 8 of the dumping conveyor device 3. As is apparent from Fig. 4, the crawler mechanism means 21, 0 which is arranged near the charging hopper 4, is fixed in a manner that the individual crawler mechanisms come to lie outside the projection of the charging conveyor device 2 so as to enable an extremely securely standing support of the charging device on the charging side end, which is subjected to dynamic 5 loads. On the dumping side end of the charging conveyor device 2, the pair of crawler mechanisms 22 can be arranged closer to the longitudinal central axis of the charging conveyor device, such a configuration of the crawler mechanism 21, 22 altogether providing an extremely stable three-point bearing relative to 30 the frame 20 of the crusher plant, which is also tilt-resistant on the uneven floor. From Fig. 5 it is apparent, by way of the example of a dumping side steerable crawler mechanism 22 of the charging conveyor 9 device 2, that the individual crawler mechanisms 22 are arranged to be pivotable about a pendulum pivot 15 extending transversely to the conveying direction so as to ensure an elevated off-road mobility of the charging conveyor device 2. The frame 19 of the two crawler mechanisms 22 is mounted so as to be rotatable about a vertical axis 18 relative to the frame of the crusher plant. Fig. 6 depicts a crusher plant 1 in plan view, wherein the same reference numerals as in the preceding Figures are used. The dumping conveyor device in this case is configured as a bridge belt conveyor 14. Figs. 7a, b, c illustrate the bridge belt conveyor 14 in different positions, wherein it is apparent that this configuration is particularly well adaptable to changes in terrain and, in particular, is especially well suited to overcome topographic steps. The bridge belt conveyor 14 is articulately (horizontally and vertically) coupled as a fixed bearing to a bench carriage 23 arranged above the stationary conveyor belt 12 and is approached to the delivery site below the crusher via a movable bearing 25 formed on the frame of the second crawler mechanism 24. The bridge belt conveyor 14 is comprised of a frame 26 including a discharge conveying means and, due to the configuration of the two bearings, can be adjusted between the mobile crusher and the stationary conveyor belt arrangement 12 as a function of the course of terrain. The vertically adjustable movable bearing 25, which is provided on the crawler mechanism 24 arranged beside the mobile crusher allows for lateral displacement, horizontal rotation about a vertical axis, and pivoting about a horizontal axis of the bridge belt 14 in the sense of arrows 27, 28 and 29, respectively. It will be understood that the term "comprise" and any of its derivatives (eg comprises, comprising) as used in this specification is to be taken to be inclusive of features to which it refers, and is not meant to exclude the presence of any additional features unless otherwise stated 10 or implied.
