The invention relates to a mobile earth preparation device with a number of shredding tools arranged on a motor-driven shaft and designed as hammers with a handle and head, wherein the shaft ends of the hammers are pivotable on components mounted on the shaft are stored.

It is in itself a soil treatment device for loosening, working through, leveling and renewing Known compaction of the soil, in which the milling tools, without exception, are positioned at an angle to the carrier shaft move on different trajectories and not have a common axis of rotation because there must be at least two shafts in order to achieve the intended milling effect to evoke.

It is also known per se to throw soil into a funnel for the purpose of making compost to shred high-speed rotating impact tools. Here are the driven parts of the mixing and Breaking tools formed by the resilient or rigid tools of a normal rotary tiller.

The devices known per se are, according to their structure and mode of operation, for certain, limited soil cultivation measures or preparation work for special types of soil.

The invention is based on the technical problem of providing a soil preparation device of the type mentioned at the beginning To train the genus with a substantial increase in performance in such a way that wet, heavy, dry, light, loamy and stony soils as well as waste and peat torn, chopped up and can be mixed and which is also suitable for the processing of mineral-containing Building rubble (plaster of paris, bricks, etc.) is suitable.

This object is achieved according to the invention in that provided with T- or L-shaped heads Hammers alternating with head-free hammers on secondary axes at a distance from the shaft are stored, with the minor axes sitting in two connecting bodies, which are on the ends the shaft are attached, and that a shaking track opposite the discharge chute in the the lower part of the trajectory of the hammer heads opens.

In a further development of the concept of the invention it is provided that the connecting body two concentrically are seated on the shaft ends disks, between which two are at the same distance and and minor axes extending parallel to the shaft are attached.

It is of particular importance that the earth preparation device at Ar-mobile

position of the device at an angle of about 45 ° at the lower end of the vibrating conveyor on a crankshaft is mounted and attached to the housing at the upper end via elastic or resilient elements.

The invention will now be explained with reference to the drawing, which shows an embodiment.

F i g. 1 shows the device according to the invention in side view;

F i g. 2 is the corresponding floor plan, and

Fig. 3 shows two different perspectives Forms of shredding hammers.

From Fig. 1 in connection with F i g. 2 is the shaft 1 driven by a motor (not shown) recognizable, which is stored at 2 and 3 and carries a fixed disk 4, 5 at each end. Included are, as in particular from FIG. 2 can be seen, these discs by two equidistant from the Main shaft 1 and secondary axes 6 and 7 arranged parallel to this are connected to one another. on the secondary axes are oscillatable, but a number cannot be displaced in the longitudinal direction of the axes Rocking hammers 8 and 9 arranged.

A dense arrangement of hammers on the secondary axes 6 and 7 is obtained in that hammers with heads 9 and hammers without heads 8 are hinged alternately. The heads of the hammers can be T-shaped 19 or L-shaped 15, as can be seen from FIG. Opposite the discharge chute 17, a vibrating plate 11 is arranged below the filling opening 12. This is caused to vibrate violently at the bottom by a crankshaft 10. At the top it is attached to the housing by resilient elements 18.

While the impact of the hammers sitting on the secondary axes 6 and 7 is primarily serve to crush stones and clods of earth, overcomes that of the rotating crankshaft

funnel 12 of the machine is stuck or clogged. So you get a valuable one through the earth shaker Complement of the demolition hammers.

The device is supported on a pair of wheels 13 and provided with a guide rail 14.

Claims (4)

Patent claims: 1. Mobile earth preparation device with a number on a motor-driven shaft arranged and designed as hammers with handle and head comminuting tools, wherein the shaft ends of the hammer are pivotably mounted on components attached to the shaft, characterized in that for the processing of all types of earth, in particular also stony soils, alternating hammers (9, 15) with T- or L-shaped heads with head-free hammers (8) on secondary axes (6) running at a distance from the shaft are stored, the secondary axes (6) sitting in two connecting bodies (4), which on the ends of the shaft (1) are attached, and that one of the discharge chute (17) opposite Shaking track (11) opens into the lower area of the movement path of the hammer heads. 2. Apparatus according to claim 1, characterized in that the connecting body is two concentric on the shaft ends (1) seated disks (4), between which two extending at the same distance and parallel to the shaft Minor axes (6) are attached. 3. Apparatus according to claim 1 or 2, characterized in that the in the working position of the Device mounted at the lower end on a crankshaft (10), inclined by about 45 ° and is fastened to the housing at the upper end via elastic or resilient elements (18). 4. Apparatus according to any of the preceding claims, characterized in that the distance the secondary axes (6) of the shaft (1) corresponds to the length of the hammer handles.
