Description

Cutter head for branch crusher

Technical Field

The utility model belongs to the technical field of the branch chip machine spare part, refer in particular to a blade disc for branch chip machine.

Background

At present, most cutter heads only have the blades at the discharge port and the blades on the fixing plate to crush twice, and the discharge of the structure is easy and unsmooth in the actual crushing process, so that the discharge efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a stable in structure, crushed aggregates are efficient, the effectual blade disc that is used for the branch crusher of ejection of compact.

The purpose of the utility model is realized like this: a cutter head for a branch crusher comprises a cutter head, a central shaft arranged in the center of the cutter head and at least two mounting shafts circumferentially distributed by taking the central shaft as an axis, wherein a fixing plate for fixing the mounting shafts is arranged at the upper end of the central shaft, and first blades are formed at two ends of the fixing plate; the cutter head is provided with at least one mounting hole, blades are arranged in the mounting hole, and teeth for crushing materials are formed on the upper end faces of the blades.

Preferably, four vertex angles of the fixing plate are respectively provided with a first installation shaft, a second installation shaft, a third installation shaft and a fourth installation shaft, the first installation shaft and the third installation shaft are respectively provided with a second blade, and the second blades are arranged below the first blades.

Preferably, the second installation axle and the fourth installation axle are all overlapped and are equipped with the third blade.

Preferably, the cutter head is provided with at least one discharge hole, and a blade for crushing materials is arranged on the other surface of the discharge hole.

Preferably, an annular groove is formed in one end face of the cutter disc.

Preferably, one end of the first blade extending out of the fixing plate is arranged to incline upwards.

Preferably, the central shaft is internally provided with a shaft hole, and the shaft hole is provided with a key slot.

Compared with the prior art, the utility model outstanding and profitable technological effect is: the utility model discloses the blade that has increased the discharge gate on crushed aggregates blade disc has solved the unsmooth problem of ejection of compact in the past. The blades are added with teeth. And crushing the crushed materials for the second time in the crushing chamber. The effect of thinning the crushed aggregates is achieved, and the efficiency of crushing the aggregates is greatly increased.

Drawings

FIG. 1 is one of the schematic structural diagrams of the present invention;

fig. 2 is a second schematic diagram of the present invention.

Detailed Description

The invention will be further described with reference to specific embodiments.

As shown in fig. 1-2, a cutter head for a branch crusher comprises a cutter head 1, a central shaft 2 arranged in the center of the cutter head 1, and at least two mounting shafts 3 circumferentially distributed by taking the central shaft 2 as an axis, wherein a fixing plate 4 for fixing the mounting shafts 3 is arranged at the upper end of the central shaft 2, and first blades 5 are formed at two ends of the fixing plate 4; the cutter head 1 is provided with at least one mounting hole 6, blades 7 are arranged in the mounting holes 6, and teeth 8 for crushing are formed in the upper end faces of the blades 7.

This technical scheme increases tooth 8 on blade 7, and the crushed aggregates can carry out the regrinding in crushed aggregates room, reaches the effect that the crushed aggregates is more refined.

Preferably, a first mounting shaft 9, a second mounting shaft 10, a third mounting shaft 11 and a fourth mounting shaft 12 are respectively arranged at four vertex angles of the fixing plate 4, a second blade 13 is arranged on each of the first mounting shaft 9 and the third mounting shaft 11, and the second blade 13 is arranged below the first blade 5.

Preferably, the second mounting shaft 10 and the fourth mounting shaft 11 are sleeved with a third blade 14.

Preferably, at least one discharge hole 15 is formed in the cutter head 1, and a blade 16 for crushing materials is installed on the other surface of the discharge hole 15.

According to the technical scheme, the discharge hole 15 is formed in the material crushing cutter head, and the problem that discharging is not smooth in the past is solved.

Preferably, an annular groove 17 is formed on one end surface of the cutter head 1.

Preferably, the end of the first blade 5 extending out of the fixing plate 4 is inclined upward. So that enough space is left between the first blade 5 and the shell, the blocking phenomenon caused by wood accumulation is avoided, the cutting force of the first blade 5 to the wood is improved, and the first blade 5 is convenient to fully cut the wood.

Preferably, the central shaft 2 is internally provided with a shaft hole 18, the shaft hole 18 is provided with a key groove 19, and the cutter head assembly is arranged on a crankshaft of the branch crusher to work through the key groove 19.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
