Machine for breaking hard materials

The invention "relates to a machine for breaking hard Materials such as asphalt or concrete.

At present, the breaking up of asphalt, concrete or the like. carried out by individual workers who use a pneumatic or similar drilling device for this purpose. this is a time-consuming and strenuous activity when breaking up surfaces of any size. The task of the present Invention consists in creating a machine

the use of which "significantly reduces the manpower required in carrying out such work.

This object is achieved according to the invention in that the machine for breaking hard materials includes a plurality of impact devices attached to a support structure are arranged and can be operated at the same time to break open a hammer, drilling or similar activity on the hard Exercise material. Preferably, several such devices are provided, the hydraulic or pneumatic Hammers included. Two rows of hammers can be attached to each a belt or carrier may be provided, the belts having a Form part of said support structure and are preferably arranged so that they move up and down and in a horizontal plane around its inner edges an angular movement can perform. The distance between the straps can also be changed. The supporting structure can be rigid be attached to a tractor or other vehicle so that it protrudes backwards at this or it can be a Form an independent unit for towing behind a towing vehicle.

An exemplary embodiment is shown on the basis of the drawing of the invention described. Show it:

Figure 1 is a side elevation of a machine according to the invention for breaking hard materials and

FIG. 2 is a plan view of the machine shown in FIG.

The purpose of the machine "is to break open a hard one Materials such as asphalt, concrete or the like. over a large area, around what is normally necessary for such an activity Reduce labor. The machine can be behind any slow moving vehicle, e.g. behind a Tractor, attached to it or towed by it. In the drawing there are eight hydraulic impact devices or hammer 5 four at a time on one of the "two" Carriers or straps 6 arranged, which are adjustably attached to a support frame 7 by means of bolts 8, which are in transverse slots 9, which are arranged in the region of the front and rear ends of the support frame 7. The support frame 7 is rotatably attached to a frame 1o by means of parallel intermediate members 11 and pins 12, whereby a parallelogram-shaped Linkage is formed so that when the support frame 7 is raised or lowered, it is always parallel to the frame 1o remains.

The support frame 7 and the two carriers held by it or

309849/0 517

Straps 6 can be raised at the same time with respect to the frame 1o and are lowered by means of a pair of hydraulic piston-cylinder units 13 '' whose piston rods are rotatable or are pivotably connected to upstanding, fixed to the frame 7 brackets or holders 14 and their cylinders connected to any suitable attachment points on the vehicle to which the machine is moored or behind to which she is being dragged. The frame 1o can be attached directly to a self-propelled vehicle, so that the Additional device on the vehicle protrudes to the rear, or it a pair of wheels 23 may be provided to allow the machine to be behind any suitable slow moving vehicle can be towed in a rigid manner.

To change the distance between the girders or straps 6, a hydraulic motor 15 is attached to the support frame 7, which drives opposing shafts 16 screwed to the foremost ends of the beams or straps 6 stand. So when the motor is operated, the two screw shafts move the girders or belts toward or away from each other away, which changes the distance between the two rows of hammers.

The rear parts of the straps or straps 6 which carry the hammers 5 are attached to pivots 1? fastened so that the straps or straps are up to an angle of 90 from the

pivoted to the rear projecting position shown in the drawing and in the desired angular position can be locked by the engagement of locking pins 18 in complementary holes in pads or holders 19 on the rear parts of the straps or straps and in square plates 2o attached to the front parts of the straps or straps. In this way, the Hammer cleans are brought into positions in which both protrude laterally from the machine in opposite views.

All hammers are turned into hydraulic fluid from a pipe network at the same time fed which extends along each bracket or strap. The operation of the hammers and the motor can be done from an operating or control unit 21, which also has a container and a pump for the hydraulic fluid contains. The pump can be driven in any suitable manner, for example by being driven from the towing vehicle takes place by means of a power transmission system.

In operation, the rows of hammers can be set at the desired spacing or the desired angular position, depending on the type the material surface to be broken up can be set, whereupon the machine is simply moved over the pool, whereby all Hammer operated at the same time. Therefore, the area can be compared with the time and effort involved in use

to be used by normal individual pneumatic drills, can be broken open very quickly and easily. J When you are finished the work, the straps or straps can be lifted off the floor and the device can be quickly moved to another location will.

Various modifications can be made without using deviate from the invention. For example, any number of hydraulic hammers or other impact devices can be used one or more straps or straps can be provided and the striking devices can be pneumatic, electromagnetic or operated in other ways. Additional breaking units can be provided if desired, with bolts between can be attached to the main straps or straps, as shown in the drawing at 22, and the in In a further embodiment, the rearmost areas of the straps or straps can work in this way be arranged that it moves a ^ angle out of the horizontal plane and adjusted up to the vertical plane which means that the machine can also be used on sloping or vertical surfaces.
