Technical Field

The utility model relates to the technical field of cutters, in particular to a crushing cutter.

Background

Timber rubbing crusher is smashing ligneous in-process, realizes smashing ligneous through broken sword extrusion timber, and at this in-process, broken sword is under ligneous impact, and broken sword structure takes place to damage easily, leads to broken sword to need often to be changed, has not only reduced work efficiency, has increased the running cost of equipment simultaneously.

SUMMERY OF THE UTILITY MODEL

Aiming at the prior art, the technical problems to be solved by the utility model are as follows: in order to overcome the defects of the prior art, a crushing cutter is provided.

In order to solve the technical problems, the utility model adopts the technical scheme that: the utility model provides a crushing cutter, includes the broken head of positive frustum of a pyramid shape, the mid point of each side of bottom surface connects gradually under the broken head forms the central plane, the central plane is inwards sunken along broken head two bottom surface center line directions, the extreme point of each side of central plane all is connected with the bottom of this side just right arris and forms the inclined plane, the both sides limit on inclined plane is the blade, is equipped with protruding piece between two adjacent inclined planes, fixedly connected with erection column on the last bottom surface of broken head, threaded bottom hole has been seted up in the erection column. The positive prismoid structure can effectively disperse and use the power on broken head, improves the intensity of broken head, combines through inclined plane and central plane, from equidirectional extrusion timber, has enlarged the broken scope of broken head, has improved the crushing effect to timber, cuts timber through a plurality of blades that form, further smashes timber through protruding piece simultaneously, further improves the crushing effect to timber.

Preferably, the shape of the convex block is a pyramid with a bottom surface adjacent to the central surface. The side edges of the pyramid-shaped convex blocks can also form cutting edges to cut wood, and the crushing effect is better.

Specifically, each side edge of the crushing head is provided with a cutting surface, and the cutting surface and the side edge formed by the intersection of the inclined surface are cutting edges. By converting point contact into line contact, not only the cutting range is increased, but also the stability of the structure is improved.

Furthermore, the crushing head, the protruding block and the mounting column are of an integrally formed structure. The integrated into one piece structure does not have the joint gap, consequently connects reliably stably, improves the stability of broken sword structure greatly.

In particular, the crushing head is shaped as a regular quadrangular frustum pyramid. The broken head of quadrangular frustum of a pyramid shape can reduce the degree of difficulty of processing of broken head when guaranteeing crushing effect.

Preferably, the inclined surface is provided with irregular grains made of hard alloy steel. The lines can enable the inclined plane to produce tearing force on the wood when extruding the wood, and the crushing effect on the wood is improved.

Specifically, the surface of the crushing head is provided with a carburized layer. The carburized layer on the surface of the crushing head can ensure that the surface layer has high hardness and wear resistance, and the toughness of the inside of the surface layer is still maintained, so that the overall strength of the crushing head is effectively improved.

Compared with the prior art, the utility model has the beneficial effects that:

1. the frustum-shaped structure can effectively disperse the force acting on the crushing head and improve the strength of the crushing head;

2. the wood is extruded from different directions by combining the inclined surface with the central surface, so that the crushing range of the crushing head is expanded, and the wood crushing effect is improved;

3. a plurality of blades through the formation cut timber, cooperate protruding piece further to smash timber simultaneously, improve the crushing effect to timber.

The reference numbers and corresponding designations in the drawings are: 1. the novel thread cutting machine comprises a crushing head, 2 parts of an inclined surface, 3 parts of a cutting edge, 4 parts of a convex block, 5 parts of a cutting surface, 6 parts of a central surface, 7 parts of a mounting column and 8 parts of a thread bottom hole.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

As shown in fig. 1-4, a crushing cutter comprises a regular frustum pyramid shaped crushing head 1, the specific crushing head 1 is in the shape of a regular frustum pyramid, the structure can effectively disperse the force applied to the crushing head 1, the middle points of the side edges of the lower bottom surface of the crushing head 1 are sequentially connected to form a central surface 6, the central surface 6 is recessed inwards along the direction of the central connecting line of the two bottom surfaces of the crushing head 1, the end points of the side edges of the central surface 6 are connected with the bottom ends of the side edges opposite to the side edges to form inclined surfaces 2, the central surface 6 is matched with each inclined surface 2, the crushing range of the crushing head 1 is enlarged, meanwhile, the inclined surfaces 2 and the central surface 6 extrude wood in different directions, the crushing effect on the wood can be improved, in the actual use process, the inclined surfaces 2 can be provided with irregular grains made of hard alloy steel, the tearing effect on the wood is achieved, and the crushing effect of the crushing head 1 is improved, the both sides limit on inclined plane 2 is blade 3, equipment impels the in-process of crushing head 1, the extruded while is sheared timber through a plurality of blades 3, in the timber extrusion process, timber is to the gathering between two inclined planes 2, be equipped with protruding piece 4 between two adjacent inclined planes 2, timber through protruding piece 4 extrusion gathering, the realization is to ligneous further breakage, as preferred scheme, protruding piece 4's shape can be bottom surface and the 6 adjacent pyramids of central plane, the arris of the protruding piece 4 of pyramid can form the blade equally and cut timber, crushing effect is better, fixedly connected with erection column 7 on the last bottom surface of crushing head 1, threaded bottom hole 8 has been seted up in erection column 7.

The inclined plane 2 is a point with the lateral edge junction of the crushing head 1 that corresponds, and during the in-service use, this point is damaged easily with the timber contact, and each lateral edge department of crushing head 1 all is equipped with cutting surface 5, and the cutting surface 5 is blade 3 with the crossing side that forms of inclined plane 2. By converting point contact into line contact, not only the cutting range is increased, but also the stability of the structure is improved.

Of course, the whole structure of the crushing knife needs to be stable and reliable, and the crushing head 1, the convex block 4 and the mounting column 7 are of an integrally formed structure. The integrated into one piece structure does not have the joint gap, consequently connects reliably stably, improves the stability of broken sword structure greatly.

The surface layer of the crushing cutter is seriously worn by long-term stress, and the surface of the crushing head 1 is provided with a carburized layer. The carburized layer on the surface of the crushing head 1 can ensure that the surface layer has high hardness and wear resistance, and the toughness is still maintained in the surface layer, so that the overall strength of the crushing head is effectively improved.

The present invention is not limited to the above-described embodiments, and various modifications made without inventive step from the above-described concept will fall within the scope of the present invention for those skilled in the art.
