Mobile edge cutter

The innovation relates to a mobile edger for floor coverings, especially Asphaltrr.atericil.

Well-known edge trimmers tend to run unsteadily and testicles lifted off and moved during the operational.

With the new feature a wheeled edger is to be created, which is characterized with low tool wear and high L _e i _s processing by an exceptionally smooth running.

According to the invention, this object is achieved by a eccentrically provided disc on a motor-driven rotating shaft released as a tool. In addition to the

Combination of the Schheidffekt with a striking effect results

a high hourly performance of the edge cutter, ι
which moreover, due to the relatively small eccentric mass in relation to the total mass of the device and the already sufficiently small eccentricity of this eccentric mass, shows a smooth run and no tendency to lift.

According to a special embodiment of the innovation, the disc is rotatably mounted on an eccentric pin of the shaft. This has the advantage that there is no rotationally fixed coupling between disk and shaft ^and the disk can rotate completely freely, which

the smoothness of the device is further increased and, moreover, the disc wear is considerably reduced, since the Disc loaded evenly over its entire circumference will.

The shaft is rotatably mounted in a receiving body, which is a further development of the innovation for height adjustment the disc is pivotable about a horizontal axis perpendicular to the shaft. This lets the working depth of the disc is infinitely variable and depending on the circumstances during the operation of the edge cutter adjust.

The innovation is explained below with reference to the description of an exemplary embodiment with reference to FIG Drawing explained in more detail.

FIG. 2 shows a section of the receiving body of the edge cutter according to FIG. 1

The mobile edger has a frame with four wheels 2 on. which is pushed by hand by means of a drawbar 3. The frame 1, which is open on one side, carries a Receiving body 4, the uir. a horizontal one in the longitudinal direction of the device extending axis 5 is pivotable.

In Aufnahirekörper 4, a shaft 6 is rotatably mounted, which is horizontal and transverse to the longitudinal direction of the Device runs. - Wave 6 occurs on the open frame string from the receiving body and carries there by means of an eccentric end pin 7 and a ball bearing 8 a steel disc 9, the edge of which is grinded and which works as a striking and cutting tool. One Cover plate 10 protects the ball bearing 8 from contamination. At the other end of the shaft 6, a pulley 11 is mounted, which has a belt (not shown) with a Diesel engine is connected as a shaft drive. For the

The ground is so chosen that the body uirt the ground. :> The thickness of the layer penetrates the ground, the depth of the penetration being stolled in as a result of the pivotability of the receiving body about the axis 5 "

The pivoting of the Aufndhinekürpers ^{l +} takes place with the help of a threaded spindle 13, which: aittig a pulley 14 hits and has a right-hand thread at one end and a left-hand thread at its other end. Both threaded ends sit in nut pieces 15 and 16, one of which 15 is articulated on a bearing block 17 protruding upward from the frame 1 and the other on a bearing block 18 protruding upward from the receiving body 4. By turning the belt pulley 14 and thus the threaded spindle 13, the distance between the articulation points of the bearing blocks 17 and 18 changes, which causes a pivoting movement of the receiving body 4. The belt pulley 14 is driven by a handwheel 19 attached to the drawbar 3, the axis 20 of which carries a belt pulley 21 which is connected to the belt pulley 14 via a belt 22. Instead of the belt drive

a chain drive can of course also be provided

By means of the handwheel 19, the depth of penetration of the steel disk 9 as a striking and cutting tool can be easily adjusted to the desired level during operation of the device. Working conditions adapted ⁴ : become.
