Description

The invention relates to a device for receiving and driving an aggregate for processing, in particular crushing, classifying and / or sorting of lumpy feed. Furthermore, the invention relates to the use of such a device for receiving and driving an aggregate, which is suitable for processing, in particular crushing, classifying and / or sorting of lumpy feed material.

Furthermore, the invention relates to a device for processing, in particular crushing, classifying and / or sorting of lumpy feed.

The treatment of lumpy feed has, for example, in the industrial treatment of mineral resources, such. in quarrying, gravel and mining, as well as in the treatment of secondary materials, e.g. in the recycling of building rubble, a great importance. The treatment comprises, in particular, the crushing, classifying and / or sorting of the lumpy feedstock. For crushing crushers are typically used. The classification is done by means of screening devices.

Crushers are referred to as when they allow a comminution of the feed material to grain sizes in the coarse to medium size range, ie to a grain size of up to 1-10 mm. In contrast, one speaks of mills, if the Zielkörnung should lie in the underlying fine or finest area. Crushers can be used both stationary and mobile (on wheels or on crawler tracks).

Mobile crushers have the advantage over stationary crushers that they can be moved on the construction site or within a demolition field. Instead of transporting the feed material from the changing locations of its seizure over long distances to the stationary crusher, which causes high transportation costs, mobile crushers can easily be tracked with the aid of their integrated chassis on the construction site or in the demolition field in order to follow the location of the material seizure , Fully mobile crushing plants with permanently installed caterpillar tracks can be filled by excavators, for example. The shredded material can then be further processed on site or transported on relocatable belt systems or with wheel loaders.

Another advantage of mobile crushers is that they can be brought to the respective site or demolition field due to the relatively low transport weight with conventional transport devices without having to be broken down into their individual components.

The mobile use of crushers is also possible through crushing buckets, especially jaw crusher. It is an attachment for excavators, which can crush with the help of built crushing jaws the feed material, such as rubble and demolition material. A crusher bucket has the design of a blade with which the material to be crushed can be picked up as with a conventional bucket and which is open at the rear for the discharge of the crushed material. Compared to normal jaw crushers, the jaw crusher has lower production but can easier to transport and requires a digger for his operation. A jaw crusher spoon is for example in the WO 2004/020747 A1 described.

The jaw bucket works with the hydraulic system of the excavator. The hoses of the excavator, for Ölzuund-Ablauf, are directly connected to the crusher bucket. A hydraulic block regulates oil flow and oil pressure to deliver the correct amount to the hydraulic motor.

During the crushing process, the crusher bucket is positioned vertically so that the material can fall out below. Crusher buckets have the following advantages in comparison to mobile crushers: Due to the design of the crusher as an attachment for excavators, the crusher can be easily removed and cultivated. This makes a simple change between different attachments possible. Furthermore, the crusher is adjustable in height because of the arrangement on an excavator, so that the respectively required distance to the ground or to a discharge device arranged therebelow can be adjusted. In particular, the crushing of steel-reinforced concrete, such as sleepers, with conventional mobile crushers is not possible because the emerging at the outlet of the crusher together with the crushed concrete steel bars have a certain amount of space in the vertical direction, which is not present in mobile crushers. Finally, crusher spoons have the advantage that the crusher can be easily tilted or jogged due to its attachment to the excavator in order to solve blockages or blockages of the excavator.

A disadvantage of crushing buckets, however, is the production standstill of the crusher during the material intake with the attachment, so that the production capacity is low. Compared to stationary crushers have systems with crushing buckets the disadvantage that the excavator, on the arm of the attachment is located, is blocked for other work.

The invention therefore aims to provide an improved apparatus for performing crushing or other treatment work, in particular classifying or sorting work, with a high production capacity to be achieved and the transport routes to be minimized.

To achieve this object, the invention provides a device for receiving and driving an aggregate for processing, in particular crushing, classifying and / or sorting, of lumpy feedstock before, comprising a stationary, in particular frame-shaped support structure and a supported on the support structure supporting element with fastening means for releasably securing the unit designed as an attachment, wherein the support member for the attachment is arranged vertically adjustable and / or tiltable relative to the support structure, further comprising a drive device for the attachment, which via coupling and / or connecting means in driving connection with a drive of the attachment can be brought.

The invention thus makes it possible to use an attachment, which is actually intended for mobile vehicles, in particular excavators, on a stationary device. At the stationary equipment, the attachment, such as a crusher bucket, used only for the preparation of the material, but not for the material intake. By such a stationary operation, the feed material from a feeder device (such as excavators, wheel loaders, etc.) is fed directly into the attachment, whereby the production stop caused by the material intake with the attachment is avoided. The constant loading of the attachment with material thus allows an increase in the production of the attachment by up to 50%. This also reduces operating costs to a minimum.

The invention also provides great flexibility because implements can thereby be used both mobile on an excavator or wheel loader as well as stationary. Since attachments are designed for rapid attachment and removal, a simple change between the two types of application is possible. Furthermore, a change between different attachments in a simple manner possible.

The device according to the invention has a stationary, in particular frame-shaped supporting construction, which supports or supports a supporting element with fastening means for releasably securing the attachment. The stationary design of the frame means that the device has no drive. Preferably, the device according to the invention also does not include a fixed chassis, such as a crawler chassis or wheels. For support on the ground, the support structure preferably comprises leidglich support legs, which are designed in particular extendable to compensate for uneven floors can. To increase the tipping safety, includes the Support structure preferably additional stabilizing elements, such as laterally extendable claws.

For the relocation of the device of the invention requires a separate transport vehicle. However, since the apparatus can be made relatively small in size, transportation is possible with conventional transport vehicles which are available anyway on a demolition field or a construction site. The transport cost here is much lower than in the case of conventional stationary crushing plants, which are building large in consideration of their compared to attachments higher production capacity and can usually be transported only with special transports or in the disassembled or partially disassembled state.

In order to use the attachment to the device according to the invention in a similar manner as on an excavator, the support member for the attachment is arranged vertically adjustable and / or tiltable relative to the support structure. The height adjustability allows you to adjust the distance of the attachment to the ground or to a conveyor below it. Due to the height adjustability, the problem of the insufficient distance between outlet and conveyor belt, which is known in the case of permanently installed units, is avoided, especially in the recycling of steel-reinforced concrete. Furthermore, the attachment can also be moved far down due to the height adjustment, to ensure at low room heights (such as in tunneling) a very low task height.

The tilting function of the support element allows a rapid emptying of the attachment either to dump unbrechbaren material or sieved oversize. The otherwise not possible with fixed tools otherwise shaking function of the support member also allows a relaxation of the feed material and thus a quick solution of blockages. This allows an additional increase in production.

The device according to the invention is further characterized by an integrated drive device for the attachment, which can be brought via coupling and / or connecting means in driving connection with a drive of the attachment. Thus, also with respect to the drive, it is possible to use the attachment similarly to the boom of an excavator or the like, i. it allows the use of conventional attachments that require an external power supply to be powered. The respective attachment is thus fed by the energy system of the device according to the invention. The attachment comprises e.g. a hydraulic motor fed by a hydraulic system of the device according to the invention, the corresponding hoses for oil supply and drainage being connected directly to the attachment.

Under an attachment is understood in the context of the present invention, an additional tool for construction machinery, with which the construction machine can perform various operations. Attachments are usually by hand or with the help of quick change devices without much effort to the respective construction machine, in particular their boom, on and of this degradable. The attachment is here preferably designed as a spoon crusher, in particular spoon jaw crusher, or as a sieve spoon.

In a preferred embodiment of the invention, the height adjustment or the tiltability of the attachment is achieved in that the support element is arranged for the attachment to a supported on the support boom, wherein the boom is designed adjustable so that the support element adjustable in height and / or tilting is. In particular, the boom comprises at least a first and a second arm, which are pivotable relative to each other, wherein preferably the first arm is pivotally attached to the support structure. This results in a construction of two boom arms, which is comparable to the boom of an excavator. The two arms are in this case preferably arranged pivotably, so that a kinematics results, with which the support member and the attachment attached thereto can be moved two-dimensionally, in particular in a vertical plane, namely a longitudinal center plane of the device. The attachment can thereby be moved in the vertical direction and in a direction transverse thereto, namely forward and backward. Lateral adjustability, e.g. by a rotation of the boom about a vertical pivot axis, would also be conceivable.

In order to enable the tiltability of the attachment, a preferred embodiment provides that the attachment for the attachment is pivotally mounted on the second arm of the boom.

The construction of the boom with two pivotable arms is preferably designed such that the on the support element fixed attachment between an operating position and a parking or transport position can be moved, wherein the arms are arranged in the park or transport position in a mutually pivoted position and form in the mutually pivoted position between them a receiving space for the attachment. Particularly preferably, it is provided that the second arm and possibly the first arm of the cantilever is or are angled. This makes it possible for the arms together in the park or transport position pivoted relative to one another to form essentially a U or C shape, which forms a receiving cross section for the attachment.

The pivoting drives for pivoting the first arm, the second arm and / or the support element preferably each comprise at least one hydraulic cylinder-piston unit.

The transport of the device from and to its place of use as already mentioned by means of a separate transport device, such as a transport vehicle. In order to facilitate the loading and unloading of the device on or from the vehicle, it is preferably provided that at least one eyelet or a hook for gripping the device with a hook lift is provided on the support structure or on a rigidly connected thereto element. The device can be grasped like a roll-off container and lifted or pulled onto the loading area of a transporting train, in particular a hook lift trailer. A particularly advantageous embodiment provides in this context that the support structure or the support frame of the Device according to the invention is designed as a base frame of a roll-off container.

The transport of the device is thus possible in a simple and cost-effective manner. The need for special caterpillars or caterpillars otherwise special transport of caterpillars or caterpillars lowbed trailer is thereby avoided. Such mobile crushers or screening devices are mobile, so they can move within a construction site with their own drive. Over longer distances, however, they must be transported using the special transport vehicles mentioned above.

A simple and quick attachment of the attachment is preferably made possible by the fact that the support element comprises an adapter plate of a quick-change system for attachments. A quick coupler system provides a standardized attachment interface, wherein the adapter plate is preferably designed to receive two parallel bolts of the attachment, wherein the boom usually engages the front bolt of the quick coupler and the tilt cylinder directly on the rear bolt.

A preferred embodiment provides that the drive means comprises a first hydraulic pump, preferably driven by a first electric motor, which is connected to form a first hydraulic circuit with a hydraulic line leading to a hydraulic motor of the attachment and a hydraulic line leading back from the hydraulic motor, the back and forth the returning hydraulic line preferably each having a connector for connection to the attachment.

With a suitable valve arrangement on the hydraulic block of the device, the respectively desired direction of rotation of the hydraulic motor can be selected. For example, a movable jaw or crushing plate of a jaw crusher can be driven in the one direction of rotation for the normal crushing operation and the other direction of rotation can be used for loosening material blocked in the crusher intake. Likewise, in the case of screen blades or blade separators, the direction of rotation of the screening or crushing rotors can be changed in order to ensure efficient screening or to release blockages.

Furthermore, a second hydraulic pump, which is preferably driven by a second electric motor, may be provided which has a drive device for the height adjustment or tiltability of the support element, in particular the hydraulic cylinder-piston units of the tilting or tilting drives, and possibly a hydraulic oil cooler for cooling the in the first hydraulic circuit flowing medium feeds.

The control of the device according to the invention by an operator is preferably carried out not by actuating operations of the operator on the device itself, but remotely controlled. The training is preferably made for this purpose so that the drive device for the attachment and / or a drive device for the height adjustment or tiltability of the support element are connected to a remotely controllable control device.

According to a further aspect, the invention provides the use of an attachment to a boom of a stationary device according to the first aspect of the invention for processing, in particular crushing, classifying and / or sorting, of lumpy feedstock.
