Benefits of technology

"The present invention provides an adapter for mounting cutting teeth on a cutter head, which is a relatively inexpensive and easily replaceable compared to the tooth or mounting block. The adapter is made of softer material than the tooth or mounting block, allowing it to deform more readily in case of a rock hit. The adapter is secured to the mounting block with a bolt and aligns the tooth with the front side of the block. The cutting tooth is mounted on the adapter, which is then secured to the mounting block with the bolt. The invention reduces the likelihood of damage to the teeth and blocks during operation and reduces the operating cost of the machine."

Problems solved by technology

The cutting heads often operate in an environment where rocks or boulders are present and these rocks or boulders are frequently hit by the cutting head.
These hits can severely damage the cutting teeth and / or the mounting blocks on the head.
The damaged teeth are relatively expensive to replace and the mounting blocks, if damaged, are even more expensive to replace since they are normally welded onto the drum.

Embodiment Construction

[0016]The mounting assembly 1 of the present invention, as shown in FIGS. 1, 2 and 3, includes a mounting block 3 having a bottom side 5, slightly concave, by means of which it is attached to the surface 7 of a cylindrical, rotatable, cutter head 9. The mounting block 3 is attached, usually by welding, to the surface 7 to be transverse to the longitudinal, rotational axis of the cylindrical head 9. The mounting block 3 has a step 11 just above the front of the bottom side 5 and a front side 13 extending up from the step 11. A stop rib 15 can extend up from the step 11, spaced from the front side 13 and parallel to it. The block has a back side 17 extending up from the rear of the bottom side 5. The back side 17 can be parallel to the front side 13. A top side 19, which angles upwardly, joins the top of back side 17 to the top of the front side 13. A bolt hole 21 extends through the block from the back side 17 to about the center of the front side 13. When the block 3 is mounted on t...

Abstract

An adapter for use in mounting a cutting tooth onto a mounting block. The adapter has two opposed sides with a first groove on one side for receiving a leading portion of the mounting block and a second groove on the other side opposite the one side for receiving a portion of the cutting tooth. The first and second grooves are aligned. The adapter has a fastening hole there through in the grooves, the hole transverse to the sides of the adapter. The fastening hole is used in fastening the tooth to the mounting block with the adapter sandwiched between the tooth and mounting block.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]This invention is directed toward an adapter for use in mounting a cutting tooth used on a rotating cutting head. The invention is also directed toward a cutting tooth mounting assembly for use on a rotating cutting head.[0003]2. Background Art[0004]Rotating cutting heads, such as heads on brush cutters, have a plurality of cutting teeth mounted over the surface of the head. Each tooth is detachably mounted on a mounting block which block in turn is fixedly mounted on the surface of the cylindrical head of the cutter. The tooth is normally fixed by a bolt directly to the block so it can be easily replaced if damaged or broken. The cutting heads often operate in an environment where rocks or boulders are present and these rocks or boulders are frequently hit by the cutting head. These hits can severely damage the cutting teeth and / or the mounting blocks on the head. The damaged teeth are relatively expensive to replace and the ...
