Abstract
A support of the steel plate conveyor module includes a receiving boom, a steel plate conveyor and a receiving hopper for a mobile crusher. The material is picked up by a dredging shovel and charged into the receiving hopper. It is fed from there by the steel plate conveyor to the crusher, where it is crushed and then discharged via the stacker belt. As the strip-mining progresses, the dredging shovel and the mobile crusher move on together. The steel plate conveyor module is raised for this purpose and the crusher moves into the next position on its caterpillar-type chassis. The steel plate conveyor module is again deposited there, and its rocker pendulum (33) adapts itself automatically to a possible slope of the subsoil (9). If the material picked up by the dredging shovel drops from the top into the receiving hopper, vibrations, which may cause damage to the supporting structure, are caused there by the impact.
Hydraulic cylinders (36, 37), each of which absorb the impact forces and introduce them directly into the subsoil (9), are arranged for this reason on both sides of the rocker pendulum (33) between the rocker pendulum (33) and the boom (30) of the steel plate conveyor module. To ensure that the possibility of adapting the rocker pendulum (33) to an uneven subsoil (9) is preserved, the hydraulic cylinders (36, 37) are connected to one another by hydraulic lines (10, 11).

Description
SUPPORT FOR THE STEEL PLATE CONVEYOR OF A MOBILE CRUSHER
FIELD OF THE INVENTION
[0001] The present invention pertains to the support of the steel plate conveyor module for a mobile crusher, which said module comprises essentially a receiving boom, a steel plate conveyor and a receiving hopper.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
[0001] The present invention pertains to the support of the steel plate conveyor module for a mobile crusher, which said module comprises essentially a receiving boom, a steel plate conveyor and a receiving hopper.
BACKGROUND OF THE INVENTION
[0002] According to the book Baumaschinen; Erdbau- und Tagebaumaschinen [Construction Equipment, Earth-moving Machinery and Strip Mining Machinery], 1 st edition, 2002, p. 358, Section 6.3, "crusher units," mobile crushers are used in strip mining, where the material picked up from large dredging shovels, wheel loaders or the like shall be loaded onto a conveyor belt continuously in a crushed state suitable for conveying on belts.
This concept completely avoids transportation with trucks, which causes high operating costs. Large mobile crushers with service weights exceeding 1,000 tons are usually moved by means of caterpillar-type (crawler - endless belt drive) chassis, comprising 2 to 6 caterpillars. The steel plate conveyor module with the receiving hopper for the contents of two to three shovels is additionally supported in operation on the ground in order not to introduce the heavy hopper loads and the impact impulse into the supporting structure of the device.
This concept completely avoids transportation with trucks, which causes high operating costs. Large mobile crushers with service weights exceeding 1,000 tons are usually moved by means of caterpillar-type (crawler - endless belt drive) chassis, comprising 2 to 6 caterpillars. The steel plate conveyor module with the receiving hopper for the contents of two to three shovels is additionally supported in operation on the ground in order not to introduce the heavy hopper loads and the impact impulse into the supporting structure of the device.
[0003] The steel plate conveyor module may be supported by a lowerable support under the steel plate conveyor module. Such a solution is known from patent specification DE 28 34 987 C2, where the impact force is introduced in an unfavorable manner into the superstructure via a hydraulic cylinder and onto the soil from the superstructure via an adjustable support. What is important in this solution is essentially to arrange the receiving boom with the receiving hopper in a height-adjustable manner, so that the loading area of the mobile crusher can be adjusted in height to a dredging shovel acting as a loading device, which stands on different planes in height.
The adjusting cylinder assumes a horizontal position in the lower position of the receiving boom with the receiving hopper, and this horizontal position passes increasingly over into an oblique position during the upward adjustment. This solution is associated with the drawback that the supporting structure still has to absorb part of the impact impulse, which has an unfavorable effect in terms of fatigue strength and may lead to cracks in the superstructure.

This solution is associated with the drawback that the supporting structure still has to absorb part of the impact impulse, which has an unfavorable effect in terms of fatigue strength and may lead to cracks in the superstructure.
[0004] Furthermore, a mobile crusher unit is known from the document DE 36 08 C2, in which the receiving boom with the receiving hopper is provided with skids at the bottom and is thus supported directly on the subsoil in the working position. The forces generated by the impact of the chunks of rock on the charging means are thus absorbed in case of a hard and rocky subsoil, but the vibrations generated in the process are not canceled and must be absorbed at first by the steel construction of the crushing plant. When the lower surface of the support cannot be adapted to the subsoil, the impact forces of the material are transmitted unilaterally as wobbles to the supporting structure of the crusher unit and thus lead to a shortening of the service life of the supporting framework.
[0005] The support of the steel plate conveyor of a mobile crusher embodied by MMD
DESIGN AND CONSULTANCY LIMITED, which crusher is described and shown under the heading "Stripping at Goonyella["] in the journal MINING MAGAZINE, January 2003 issue, pages 15 and 16, represents an improvement. The entire steel plate conveyor module is articulated in this embodiment to the supporting structure approximately in the nuddle of the device via axles and is carried during displacement completely by two pulling cylinders, which are connected to jibs of the swiveling leaf form [sic - "blattform" in German original is a probable typo for "plattform" meaning "platform" - Tr.Ed.]. Following displacement, the steel plate conveyor module is partially deposited onto a one-point support under the receiving hopper. To maintain the balance of the device, the force of the cylinder is, however, maintained at a constant value at approx. 80% of the lifting force during displacement. All additional forces from the material contained in the hopper and the impact impulse are supported directly under the hopper.
The MMD solution comprises an additional boom supporting structure with two-point support in the middle of the device and one-point support under the receiving hopper. The lateral forces of the steel plate conveyor module are absorbed by sliding elements into the lateral brackets, with which the cylinders are also coupled. Drawbacks, which result from an eccentric impact impulse, can be recognized in practice in this type of support. Namely, this eccentric impact impulse causes shock-like lateral forces, which are fully introduced at the top into the supporting structure and lead to damage (cracks) in the steel structure.
SUMMARY OF THE INVENTION
100061 The basic object of the present invention is to provide a support for the charging means of a mobile crusher unit, which charging means comprises a receiving belt and a charging hopper, which can automatically adapt itself to an uneven subsoil, which can directly introduce the forces generated from the transfer of the material directly into the subsoil over the shortest path, which also absorbs lateral forces and with which the shocks generated during the itnpact of the chunks of material can be absorbed.
[0007] This object is accomplished by arranging under the receiving hopper a rocker pendulum, which acts like a one-point support after being deposited after the displacement, but which acts as a two-point support during operation by means of two hydraulic cylinders, which are blocked, and also directly introduces the lateral impulses downward into the soil. The connections between the two hydraulic cylinders are necessary to make it possible for the rocker pendulum to be able to automatically adapt itself to possible unevennesses of the soil. If a throttle is integrated in the connection lines, the receiving hopper is not so rigid during the impact of the material from the dredging shovel but can yield somewhat.
[0008] The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which the preferred embodiment of the invention is illustrated.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] In the drawings:
[0010] Figure 1 is a side view of a mobile crusher according to the invention;
[0011] Figure 2 is a view showing the suspension of the steel plate conveyor module at the superstructure of the crusher; and [0012] Figure 3 is a view showing the lower support of the receiving-side end of the steel plate conveyor module.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] Referring to the drawings in particular the mobile crusher comprises, according to Figure 1, essentially the substructure 1 with the caterpillar-type chassis, the superstructure 2, the steel plate conveyor module 3, the crusher 4, the intermediate belt 5 and the stacker belt 6. The boom 30, the steel plate conveyor 31, the receiving hopper 32, and the rocker pendulum 33 belong to the steel plate conveyor module 3. The boom 30 is articulated at the top to the superstructure 2 in a horizontal swivel axle 7. According to Figure 2, the boom is adjustable in height by means of the two hydraulic cylinders 34, 35 subjected to tensile stress. The boom 30 is connected at the bottom to the rocker pendulum 33 via the joint 8. The axis of the joint 8 is directed such that the rocker pendulum 33 can adapt itself to the unevennesses of the subsoil 9.
[0014] The material is picked up from the dredging shovel and loaded into the receiving hopper 32. It is fed from there by the steel plate conveyor 31 into the crusher 4, crushed there and sent onto the intermediate belt 5 located under it. The material is released from this intermediate belt 5 via the pivotable stacker belt 6 onto a downstream face conveyor.
[0015] After the dredging shovel has advanced by a certain stripping section, it is brought into the next position. The mobile crusher must perform this backward motion to enable the material to be emptied into the receiving hopper 32 over the short path from the dredging shovel.
The steel plate conveyor module 3 is raised for this during the return motion by actuating the two hydraulic cylinders 34, 35. After the new position has been reached, the steel plate conveyor module 3 is lowered again until the rocker pendulum 33 lies completely on the subsoil 9. It can automatically compensate possible transverse slopes of the subsoil 9 due to its articulated mounting.
[0016] A shock-like load is generated during the impact of the material from the dredging shovel on the steel plate conveyor module 3. In order not to introduce this [load] into the superstructure 2 via the boom 30 and the two bolts thereof, which are arranged in the swivel axle 7, the lower support by the rocker pendulum 33 is designed according to Figure 3 as a laterally stable support. This is achieved by arranging a hydraulic cylinder 36, 37 each on both sides of the rocker pendulum 33. The two hydraulic cylinders 36, 37 are connected to one another hydraulically, so that closed hydraulic circuits are formed and the rocker pendulum 33 can adapt itself to the existing lateral unevennesses of the subsoil 9 during putting down. The shock-like lateral forces occurring during the impact of the material are thus introduced from the receiving hopper 32 into the subsoil 9 via the hydraulic cylinders 36, 37 and the rocker pendulum 33. To obtain a certain characteristic of the absorption properties, throttles 12, 13 may be integrated in the hydraulic lines 10, 11 connecting the hydraulic cylinders 36, 37.
[0017] While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
