Tooth for grabs and shovels of construction machinery

The innovation "concerns a tooth for grippers and Shovels for construction machinery, which can be connected to the old gripper or shovel at a later date and which is subject to severe wear during operation, the tooth having a shaft which can be inserted and fastened in a sleeve on a Nesser of the gripper or the shovel

Legume creams are already known that with their Shaft can be inserted into a sleeve, the sleeve is rerochweifit with a shovel or excavator aoeaer. Pie sleeve, which is open at the front and bottom when not welded, is opened on three sides with the knife welded so that calibrated a front receiving opening for receiving the shaft of the sleeve cream results.

HUlSfMaAn inserted into the sleeve. will subsequently fixed in the cave.

These sleeve teeth have the great advantage that they are fluted Teeth can be exchanged for new ones relatively easily. Such an exchange can be quick be mentioned. The known sleeve teeth, however, have some parts. The underside of the Httlsensähne It runs flush with the shovel or excavator ■ eater. Bs has shown that such teeth not only on their front edge, but also on their underside are subject to severe wear and tear. In the case of the well-known Sttlsensähnen, the underside is grooved of the tooth and on the same side also the underside of the shovel or excavator knife. One of those Wear of the undersides leads to the fact that the knife leading edge is at least in the course of time The area of the underside is so badly worn that it is no longer flush with the corresponding display edge of a newly used sleeve cream runs. As a result of the heavy loads these Teeth are subject to a secure hold of such a sleeve cream is no longer guaranteed. Farther Over time, the underside of the knife can wear out so much that the remaining thickness of the knife is no longer sufficient to absorb the stresses, which means a new knife must be used.

It should also be mentioned that the above-described wear on the knife is much greater than that

of the tooth, since usually the tooth consists of one essential more wear-resistant material than the Hesser.

The job of hiring is to address these known disadvantages to eliminate.

In the case of a tooth of the type mentioned above, this The object is achieved in that, according to the new entry, the underside of the tooth protrudes over this knife edge at least in the area of the front lower knife edge. The underside of the tooth protruding over the knife edge is the knife edge and the the subsequent underside of the knife is adequately protected against wear.

The drawings show an embodiment of the object according to the innovation. ] äs represent:

2 shows a section along the line XI-II in Pig. 1,

fig. 3 shows a side view of part of the device according to FIG. 1.

In the arrangement according to fig. 1 to 3 with the knife 1 is a sleeve 2 open at the front on three sides welded. The sleeve tooth 3 has a shaft 4

; 4 · γ can be opened into the sleeve 2 from the front. The underside 5 of the tooth 3 protrudes at least in the area of the front lower knife edge 6 over this. In the example shown, the entire underside of the tooth 3 protrudes over the entire length and width over the front lower knife edge 6 and runs essentially parallel to the underside of the tooth 7Bas dimension with which the underside 5 of the tooth 3 protrudes over the underside of the tooth 7, is designated in Fig. 1 with "e. ^N. In this way, both the front lower knife edge 6 and the underside of the tooth 7 are protected from wear by the protruding underside 5 of the tooth 3.

In modification of the Pig. 1 shown '^ iepielee can the underside 6 of the tooth 3 overlap the front lower knife edge 6 at its rear edge 8.

For fastening the sleeve connector 3 in the sleeve 2 there is a support piece 9. There are two for each purpose opposite sides 10, 10 'of the sleeve 2 recesses 18, 18 * provided. The shaft 4 of the sleeve tooth 3 has a corresponding recess 12. In the example shown, the recess 12 in the shaft part 4 is a hat. Piping runs on the underside of the sheep tee 4. Bie recesses 18, 18 * on the sleeve sides 10, 10 * run upwards pocket-shaped (11, 11 ') and take one each Side legs 13, 13 * of the U-shaped holding piece 9.
