Definitions

  • the invention relates to a plant for crushing and processing material, such as building and road construction material, in particular roadway opening according to the preamble of claim 1.
  • a mobile ballast processing plant which consists of a crusher and a screening device. Both parts of the system are coupled together for transport. In operation, the trolley for the screening device is removed and the screening device is partially supported by the crusher chassis.
  • Such a processing plant is semi-mobile, i.e. Although it can be moved along a road construction site, it remains stationary during production. Such semi-mobile systems have the advantage over the stationary that they can be set up and converted faster and with less effort.
  • a semi-mobile system has also become known from DE-GM 87 12 219. It has two mobile units, each with a crawler track. The mobile units can be brought to the construction site with the help of a flat bed trailer and they can also be moved forward together on the construction site. It is therefore not necessary for the mobile units to be realigned to one another at the new production site. A continuous production during the advance movement of the mobile units is not possible with the known system. There is also the risk that due to the existing and possibly constantly changing transverse inclination of the undercarriage, the crusher has a more or less pronounced skew. The crushing tools are subject to severe wear. Breaking tools are relatively complex, and installing and removing the breaking tools inevitably leads to an interruption in production.
  • the invention has for its object to design a system for crushing and processing material, in particular roadway opening, that it can be moved forward along predetermined route sections with minimal wear and low dust generation during production operation.
  • the crusher is supported on the chassis so as to be pivotable about an axis which runs approximately in the longitudinal direction of the associated mobile unit.
  • Actuators for example hydraulic cylinders, between the undercarriage and the crusher are controlled by a control device in order to control the crusher independently of the inclination of the undercarriage with respect to the transverse axis in the Keep horizontal.
  • the entire structure of the first mobile unit, which supports the feed hopper, the crusher and the drives, among other things, is pivotally supported on the chassis about the longitudinal axis.
  • the control device has an inclinometer, and the crusher is held horizontally in accordance with the output signal of the inclinometer, regardless of the inclination of the undercarriage, along a transverse axis running transverse to the longitudinal axis.
  • the system according to the invention is preferably designed as a train in which the first and second mobile units are mechanically coupled.
  • One or both mobile units form the towing vehicle and one or both mobile units contain a driver's cab from which the forward movement of the train is controlled, the running gear being designed so that cornering is also easily possible.
  • At least one mobile unit is therefore provided with a steering gear, for example to make the speeds of the two drive chains different.
  • the suspension and the chassis are designed so that they can easily withstand the loads during moving production.
  • the driver's cab expediently also contains the control center for the operation of the system according to the invention. Therefore, the plant parts connected to each other via signal lines.
  • the energy is generated autonomously in the mobile units, ie the mobile unit has an energy generator, for example an internal combustion engine, which drives, for example, an electric generator for generating electrical energy and / or a hydraulic pump for providing hydraulic energy.
  • the formation consisting of the two mobile units can also comminute and process material while the vehicle is moving without there being any risk of the crusher wearing out quickly.
  • the inclination compensation also ensures that the crusher is held horizontally with respect to the transverse axis, so that the material entered is evenly distributed over the crushing tools.
  • the material outlet of the crusher for example a jaw or impact crusher, is preferably located on the underside.
  • the conveyor must therefore be arranged below this outlet. Because of the transport, for example under motorway bridges, the lane units must not exceed a predetermined height. On the other hand, the conveyor must maintain a certain distance from the ground. There is therefore a risk that There is relatively little clearance between the material outlet and the conveyor. However, this is disadvantageous for the operation of a crusher.
  • the distance between the crushing tools or the material outlet and the conveyor should be as large as possible. This is achieved in one embodiment of the invention in that a scraper conveyor is arranged under the material outlet of the crusher.
  • a scraper conveyor is a known means of conveyance in which the conveyed material is pushed on with or without a base through sheets fastened to a link chain perpendicular to the conveying direction. Scratch conveyors are normally only used in mining.
  • the combination of a crusher with a scraper conveyor has the advantage that it is possible to work with a low overall height, so that the maximum distance between the crusher outlet and the scraper belt can be selected.
  • an embodiment of the invention provides a protective device, which in particular protects the chains of the scraper conveyor against wear due to falling material.
  • this protective device consists approximately in the fact that two funnel-like plates are arranged below the material outlet of the crusher. The weird arranged plates partially divert the material coming from the crusher, so that it only falls on the sheets of the scraper conveyor.
  • a nebulizing device is arranged below the crusher outlet.
  • the arrangement of the nebulizer below the crusher outlet combats the dust development at the point where the dust arises or exits the crusher.
  • the crusher tools act on dry material. There is therefore no increased wear from water. By atomizing the water, a very large, yet low-water volume of moisture is obtained, which can come into contact with as many dust particles as possible. At the same time, water consumption is minimal.
  • conical jet nozzles can be used for atomization, as have become known per se from mining.
  • an embodiment of the invention provides that the nebulization device is assigned a nebulization control which controls the dispensing of liquid as a function of the volume of material. According to a further embodiment of the invention, this takes place in an advantageous manner in that the power consumption of the drive motor for the crusher is measured, in particular the current consumption of an electric motor. Because of its variable power output, an electric motor is particularly suitable for driving a crusher. The amount of water used for atomization can therefore be delivered in proportion to the current consumption of the electric motor. For this For example, a solenoid valve in the lines leading to the nozzles is controlled by a signal that is proportional to the measured current for the drive motor.
  • an advantageous embodiment of the invention provides that a third mobile unit is provided which can be mechanically coupled to the second road unit and which has a chassis, a bunker, a conveyor for discharging material from the bunker, the comminuted material can be continuously fed into the bunker with the help of the third unit, while the conveyor assigned to the third unit is only switched on when the material from the bunker is, for example, on Vehicle can be loaded.
  • the third mobile unit thus represents a buffer that ensures continuous production; through it is avoided that when a vehicle is changed to a heap is produced.
  • the bunker and the conveyor are preferably mounted on the undercarriage so as to be pivotable about a vertical axis, preferably with the aid of a slewing ring.
  • the finished crushed grain mixture can thus be dispensed in a swivel radius of, for example, up to 360 °.
  • an embodiment of the invention provides that at least the sections of the conveyors projecting from the mobile units are pivotably mounted about a horizontal axis and can be actuated by means of adjusting members.
  • the conveyor sections can also be swiveled mechanically or hydraulically around a vertical axis so that the entire train can take corners during production.
  • an embodiment of the invention provides that the output conveyor of the first mobile
  • a magnetic separating device is assigned to the unit or the feed conveyor of the second mobile unit and a container for receiving the separated metal parts is attached to the relevant mobile unit.
  • the separator is preferably a magnetic belt separator, one end of which is located above the conveyor in question and the discharge end of which is above the container.
  • Such belt separators are known per se.
  • the deposited metallic material is dumped on a heap. This is unsuitable for a moving shredder, since the metal parts must then be collected.
  • the deposited metal parts are therefore placed in a container, which is preferably detachably attached to a mobile unit. It is particularly advantageous to attach the magnetic separator to the mobile unit having the sieving station.
  • a further embodiment of the invention provides that the container is a scrap press or the like assigned.
  • a side wall of the container can be designed as a stamp of a hydraulic press in order to compress the iron pieces, usually reinforcement, into a package of lower volume.
  • the package can then be removed from the container via a delivery opening which can be closed by a flap, a slide or the like. It can be collected by a trolley or the like traveling next to or under the container. However, it can also easily fall to the floor and then be collected and removed by a suitable holding device.
  • Fig. 1 three mobile units 1, 2, 3 can be seen, which can be moved forward on crawler tracks 4, 7 and 5.
  • the mobile units are mechanically coupled and thus represent a train.
  • the mobile unit 1 has a platform 4a which is supported on the chassis 4 in a manner to be described. It stores a feed hopper 9 and a crusher 1a, for example a jaw or impact crusher.
  • a conveyor device is provided below the outlet of the crusher, of which only the section 20 leading outwards and upwards can be seen in FIG. 1.
  • An internal combustion engine 16 is also arranged on the platform and is responsible for the energy supply for the individual drives of the crusher 1a, the undercarriage 4 and the conveyor. The drives are not shown in Fig. 1.
  • the mobile unit 2 has a screening station 2a, a driver's cab 21 and a conveyor belt 10 which extends to the top right in FIG. 1.
  • the mobile unit 2 can also have an internal combustion engine for driving the undercarriage 7, the conveyor belt 10 and the screening station 2a, but it can also be supplied with energy by the internal combustion engine 16.
  • the third mobile unit 3 has a platform 3a which can be rotated on a rotating ring 15 about a vertical axis and on which a bunker 14 and an internal combustion engine 17 are arranged.
  • a driver's cab 8 is also provided.
  • a vertically adjustable conveyor belt 11 is also connected to the platform 3a.
  • the conveyor belt sections 10 and 20 can also be adjusted in height. They can also be pivoted to a limited extent about a horizontal axis, but this is not shown.
  • the mobile units 1 and 2 are also assigned hydraulically actuated supports 7a for support and height compensation in stationary operation.
  • Another conveyor belt 6 extends from the screening station 2a to the mobile unit 1 to the front end or rear end of the unit 1.
  • the mobile unit 3 which, like the mobile unit 1, is designed as a towing vehicle, is also mechanically coupled to the mobile unit 2. In addition, both units are connected to one another via signal or command lines.
  • the formation shown can move forward on a surface, for example a roadway 13a, with either the mobile unit 1 or the mobile unit 3 acting as a towing vehicle, depending on which is in the front.
  • the formation is controlled from the driver's cab 21 of the unit 2, from which the travel gears of the mobile units 1, 2 and 3 are controlled. In the present case it should be assumed that the mobile unit moves from left to right.
  • Road opening 13 is, for example, an excavator, not shown, which moves as a separate unit during the advance movement, in the feed bunker 9.
  • the mobile unit 1 can expediently be provided with an excavator bucket attached to a boom.
  • the crushed grain mixture from the crusher 1a is conveyed via the conveyor belt 20 to the screening station 2a.
  • the oversize grain 19 is conveyed back onto the carriageway 13a in the region of the break 13 via the conveyor belt 6 and can be re-entered into the feed hopper 9.
  • the screened grain mixture is in 10 on the conveyor belt the bunker 14 of the unit 3 serving as a buffer vehicle.
  • the crushed grain mixture 18 is fed out of the bunker via the conveyor belt 11, for example into a transport vehicle 12.
  • the buffer unit 3 thus ensures continuous production of the mobile system even when the vehicle is changed.
  • the entire system can be in continuous operation even during the advance movement.
  • a housing 22 of the crusher 1a is indicated schematically in FIG. 2.
  • the rotor 23 is arranged on a shaft 23a on which V-belt pulleys 23b are seated. They are used for coupling to a drive motor, preferably an electric motor (not shown) via V-belts.
  • the material outlet 40 for the crushed grain mixture is located below the rotor 23.
  • Two funnel-like plates 26 are located below the material outlet 40 and guide the material to a scraper conveyor 41.
  • the scraper conveyor has two drive chains 42, 43 which are guided endlessly and are driven by a suitable drive (not shown).
  • the chains 41, 42 are guided in an E-shaped housing 44 and 45 and are thus secured against impairment.
  • a housing 44, 45 connects the upper and lower runs Sheet 46 on which the upper run slides.
  • the strands contain plates 47 as are known per se for scratch conveyors.
  • the scratch conveyor 41 has a very low height. It conveys the crushed grain mixture falling from the material outlet 40 onto the conveyor section 20 according to FIG
  • a plurality of spray nozzles 24 are arranged, which are connected to a water tank in the mobile unit 1 (FIG. 1) via lines (not shown).
  • a pump conveys the water from the tank to the nozzles 24 via a control valve, also not shown.
  • the control valve is activated via a control device 24a, which in turn receives a control signal via a line 24b from an ammeter 24c, which measures the current in an electrical line 24d, which supplies the electric drive motor, not shown, for the crusher 1a.
  • the water discharge of the nozzles 24 into the space 25 between the plates 26 is therefore proportional to the current in the line 24d. Since this current corresponds to the power of the electric motor, the amount of water released is also proportional to the amount of broken material.
  • the nozzles 24 are designed as cone-jet nozzles and generate a very fine water mist, so that with a small amount of water a maximum moistening of the crushed-grain mixture, but especially of the dust, is achieved.
  • the humidification can be controlled in such a way that the development of dust is largely suppressed, but the crushed grain mixture does not receive more than its natural moisture. This way, very little water is required. Above all, this protects the following parts that come into contact with the crushed grain mixture. Moist crushed grain mixture naturally results in higher abrasion than dry one.
  • the crawler chassis 4 according to FIG. 1 can be seen in an end view with the crawler belts 28. Furthermore, one of the axles 28a can be seen.
  • the axles support the platform 4a pivotably about the longitudinal axis of the unit 1 via a bearing component.
  • the pivot point on the axis 28a is designated 28c.
  • Hydraulic cylinders 31 are also articulated on the axis 28a, the pistons of which are articulated on the platform 4a. With the help of the hydraulic cylinders 31, the platform 4a can thus be changed in its transverse inclination.
  • the measuring device 30 is connected to the hydraulic cylinders 31 via a control device 30a.
  • the arrangement is such that in the event of a deviation from the horizontal, the measuring device 30 sends a signal to the control device 30a, as a result of which the hydraulic cylinders 31 are actuated so that the platform 4a assumes the horizontal position again.
  • the platform 4a therefore always maintains its horizontal orientation in the transverse direction regardless of the inclination of the ground to which the undercarriage 4a inevitably adapts.
  • a magnetic separating device 50 is arranged above the conveyor 20.
  • a frame 52 is fastened to the mobile unit 2 and rotatably supports a driving roller 53 and a driven roller 54.
  • a conveyor belt 55 is wrapped around the rollers 53, 54. It is driven by an electric motor 56.
  • the conveying direction of the conveyor belt 55 is transverse to that of the conveyor 20 which conveys crushed grain mixture 56 from the crusher 1a to the screening station 2a.
  • a magnet (not shown) is arranged between the strands of the conveyor belt 55, which causes it to be carried along on the belt 20
  • Metal parts as shown for example at 57, are drawn against the lower run of the conveyor belt 55 and are transported in the direction of the arrow 58 shown in broken lines from the region of the conveyor belt 20.
  • a container 60 is arranged, which has eyelets 61 on opposite end faces. With the help of the eyelets 61, the container 60 can be hung on vertical bolts (not shown) of the mobile unit 2. Above the container 60, the magnetic effect diminishes and the parts carried by the belt 55 fall into the container 60. When the container 60 is filled, it can be removed from the mobile unit 2 with the aid of a suitable lifting vehicle and driven to a collection point or the like. Then a new container is attached.
  • a scrap press or the like can be associated with the container 60 (not shown).
  • a stamp that can be actuated by one or more hydraulic cylinders can be arranged in the container 60, which in the initial position runs parallel to an end wall of the container 60 and with which the material in the container 60 can be compressed into a package of small volume.
  • Such a press ram can simultaneously form a side wall of the container 60.
  • An opening (also not shown) in another side wall or in the bottom of the container is closed and opened via a flap, a slide or the like in order to let a compressed package fall out.
  • the side wall of the container opposite the stamp can also have such an opening so that the stamp can be used at the same time to remove the compressed package.
  • a stamp 70 is indicated in dashed lines in FIG. 4, which is located in the container 60 and which can be actuated by a hydraulic cylinder 71 attached to the outside of the container in order to compress the iron pieces in the container 60, and on the opposite wall. As already mentioned, this can have a delivery opening, through which the package is then pushed out with the aid of the stamp.
