This will break the concrete in turn at least initiated via the teeth, the cutting edge of the This protects the plate.
- Another object of the invention is the concrete crusher to be designed so that the concrete is broken in an optimal way and the cutting edges of the cutting elements are protected.
- the teeth in the jaws are arranged that when the pliers are closed, the back teeth on the impact the concrete part to be broken off and the concrete is broken in this area and only then engage the front teeth. This will make it Breaking the concrete easier.
- Placing additional teeth between the pairing teeth Teeth on the second jaw as described above are, can also be used in concrete crushers that are not compatible with the interchangeable cutting elements described above is equipped, but in every type of concrete crusher, in which concrete crushing areas and cutting areas are provided for cutting the reinforcing iron.
- the concrete crusher consists of a first jaw 1 and a second jaw 2.
- This first jaw 1 and the second jaw 2 are connected to each other via a joint 3 and about an pivot axis 4 formed by the joint 3 from an open one Position, as shown in Fig. 1, in a closed position movable.
- This opening and closing of the concrete crusher takes place in a known manner
- Kind by hydraulic cylinder 5, for example, in Fig. 9 schematically are shown.
- This concrete crusher can in the usual way on one Construction machine attached, can be brought into any position by this be while the hydraulic cylinders 5 over one in this construction machine provided hydraulic unit can be controlled.
- the first jaw 1 of this concrete crusher is through a Frame body 6 formed, which has a free passage on the inside.
- the second jaw 2 is formed by a body 7, which when closing the concrete crushing pliers penetrate into the frame body 6 of the first jaw 1 can.
- the first jaw 1 has first concrete breaking areas that one each attached to the lateral areas 8 of the first jaw 1 rear tooth 9 and a front tooth 10 exist.
- the rear Teeth 9 and the front teeth 10 of the first jaw 1 are open screwed a web 11, which is attached to the outside of the frame body 6 is. This allows the rear teeth 9 and the front teeth 10 from the first jaw 1 removed and replaced or replaced become.
- On the lateral areas 12 of the second jaw 2 also each have a rear tooth 13 and a front tooth 14 attached serve as concrete crushing areas and on a web, not shown, the is attached to the inside of the second jaw by screwing are attached. Centered between the two front teeth 14 of the second Pliers jaw 2, an additional tooth 15 is attached.
- This additional Tooth 15 projects over the two front teeth, which can be reached thereby Effect will be described in detail later. It is also between the rear Teeth 13 of this second jaw 2 an additional tooth 16 attached, which is not visible in FIG. 1, but in particular taken from FIG. 17 can be.
- first cutting elements 17 are used, which consist of a circular arc Block 18 are formed.
- the rear tooth 13 and the front tooth 14 of the second Pliers jaw 2 used first cutting elements 17 of the same type arcuate block 18 are formed.
- On this circular arc Blocks 18 and their attachment in the first jaw 1 and the second Pliers jaw 2 will be discussed in more detail later.
- second cutting elements 20 are attached, which consist of a Plate 21 are formed. Also on these plates 21 will be closer later received.
- FIG. 2 in which the second jaw 2 is shown, but the first jaw 1 is designed accordingly the first cutting elements 17 each of a circular arc Block 18.
- This block 18 has a convex surface 22 and can thus in Receiving pockets 23 of the first jaw 1 and the second jaw 2 are used that the convex surface 22 on a corresponding Support surface 24 of the receiving pocket 23 rests. They are kept Blocks 18 in the receiving pockets 23 in each case on the end faces 25 thereof Stop surfaces 26 abut. These stop surfaces 26 are on the one hand through the rear and front teeth 9 and 10 of the first jaw 1 or 14 and 15 of the second jaw 2 formed during the stop surface 26, which lies in the area of the joint 3, on the first jaw 1 or the second jaw 2 is formed.
- the first cutting elements 17 forming blocks 18 in a simple manner in the jaw 1 or 2 inserted and by screwing the rear teeth 9, 13, or front teeth 10, 14 attached to the corresponding jaw 1 or 2 become.
- a replacement of these blocks 18 can thus be carried out very quickly only the rear tooth 9 or 13 has to be removed become.
- the blocks 18 of the first jaw 1 and the second jaw 2 are identical. You can thus freely among each other be replaced. This is a confusion when inserting the Blocks 18 in the jaws 1 and / or 2 excluded, a different Wear and tear can be compensated for by mutual exchange become.
- FIGS. 3-5 The cutting process with these first cutting elements 17, the formed by blocks 18 is shown in FIGS. 3-5.
- the reinforcing iron 27 enters the area of the concave surfaces 28 of the blocks 18, as will be seen later.
- the concave surface 28 and the side surfaces 29 of the blocks 18 each form a cutting edge 30.
- the blocks 18 can thus in the corresponding Pliers jaw 1 or 2 are used that one or the other Cutting edge 30 for cutting the reinforcing iron is in use.
- the concave Surface 28 is equipped with a curvature 31, whereby a wedge angle ⁇ arises, which is greater than 90 °, preferably about 105 °.
- the reinforcing iron 27 lies first on the domes 31 of the cooperating blocks 18, like this 4 can be seen.
- the reinforcing iron 27 is thereby held before the cutting edges 30 begin their cutting process. This will avoid that when the concrete crusher is closed further, the reinforcing iron 27 can be drawn into the cutting gap.
- the on the Block 18 forces are cheaper, the cutting process, as shown in Fig. 5, is done in an optimal manner, since that to be cut Reinforcing iron 27 does not have the tendency to become jammed in the cutting gap which, in turn, would tend to expand. As a result, the cutting edges 30 are optimally stressed, the service life the first cutting elements 17 is extended.
- each block 18 equipped with a guide rib 32 in the area of the convex surface 22, which engages in a groove 33 in the respective receiving pocket of the first Pliers jaw 1 and the second pliers jaw 2 is molded. This will an optimal mounting of the blocks 18 in the corresponding pockets the first jaw 1 and the second jaw 2 received.
- each of the second Cutting elements 20 each from a plate 21.
- Each against the cutting plane directed surface 34 has a curvature so that each point of this Surface 34 from the pivot axis 4 of the concrete crusher the same distance having.
- the surface 34 which is provided with a curvature, opposite side surfaces 35 form together with this Surface 34 is a cutting edge 36.
- One of the side surfaces 35 is in each case in the state inserted into the jaws 1, 2 by a support surface 37 supported, the receiving pocket in the front area of the concrete crusher forms.
- the plate 21 is located opposite the curved surface 34 Surface on a wall 38 adjacent to the support surface 37 first jaw 1 and the second jaw 2 and is against this screwed.
- these plates 21, which are the second cutting elements 20 form can be exchanged in a simple manner. Since the plates 21 are symmetrical, they can also be rotated so that the one or the other of the cutting edges 36 is in use.
- the side surfaces have 35 indentations 39 and projections 40.
- the reinforcing bars 27 are pushed into the indentations 39, and then clamped by the side surfaces 35 as shown in FIG. 7 is.
- the reinforcement bars 27 are closed the cutting edges 36 are cut, the forces acting on the plates 21 which want to pull the plates together.
- the cutting gap does not widen, but the opposite happens, whereby an optimal cutting effect is achieved.
- the wedge angle the cutting edge is greater than 90 °, preferably about 105 °, which, as mentioned, the cutting edges are protected.
- FIG. 17 it can be seen how the additional tooth 16 in the second jaw 2 is arranged. About halfway between the two rear ones A plate 42 is attached to teeth 13 in the second jaw 2 which the additional tooth 16 is attached. As can already be seen from FIG. 1 is, the additional tooth 15 is attached to this plate 42. The additional tooth 16 is, as can be seen in FIG. 17, on the two rear teeth 13 of the second jaw 2. Also the additional one Tooth 15, as can be seen from FIG. 1, stands over the two front teeth 14 of the second jaw 2. The mode of action of each of these front teeth 14 or above the rear teeth 13 additional Teeth 15 and 16 of the second jaw 2 in connection with the Teeth 9 and 10 of the first jaw 1 will be discussed in more detail below described.
- the concrete crusher is opened with the first jaw 1 and the second jaw 2, for example, via a concrete slab reinforced with reinforcing iron 27 41 brought, as can be seen in Fig. 9.
- the first jaw 1 and the second pliers jaw 2 are then turned over the hydraulic cylinders 5 the joint 3 slowly closed.
- the back teeth 9 of the first jaw 1 come to bear on the concrete slab 41.
- the additional tooth 16, which is centered between the rear teeth 13 of the second jaw 2 is located and is above this, also presses on the concrete slab 41. As can be seen from Fig. 10, this causes a bending effect on the concrete slab generated, the concrete begins to break under the bending forces that occur, as shown schematically in Fig. 10.
- the closing movement of the concrete crushing tongs continues as 13 and 14, the concrete breaking process, which in particular through the rear teeth 9 and 13, through the front teeth 10 and 14 and through the additional teeth 15 and 16 of the first jaw 1 and the second jaw 2 has been almost completed.
- the first cutting elements 17 and the second cutting elements 20 have been little involved in the concrete crushing process and are therefore spared.
- the wedge shape of the teeth now causes the reinforcing iron to the area of the first cutting elements 17 is pressed, as shown in FIG. 13 is shown. When closing the reinforcement iron 27, the are located in the area of the first cutting elements 17.
- the material from which the blocks 18 and the plates 21 are made are made of steel with a hardness of around 58 HRC.
