Abstract

The invention relates to crushing teeth of a crusher, in particular to replaceable crushing teeth which is used for the crusher under high crushing strength and large impact loads. The crushing teeth comprise a tooth base and crushing teeth, wherein the crushing teeth have a conical and cylindrical structure, and are fixed to the tooth base by clamp nuts at the tail ends of the crushing teeth. Compared with the prior art, the crushing teeth have a simple structure, and are convenient to replace, and particularly reliable in performance under the work conditions of high crushing strength and severe impact; and the running and maintenance cost of equipment can be reduced effectively, the overhaul time can be saved, and the production efficiency can be improved.

Description

The replaceable crushing teeth of high strength

Technical field

The present invention relates to the crusher in crushing tooth, the replaceable crushing teeth of disintegrating machine under especially a kind of high breaking strength, the heavy shock loads.

Background technology

Crushing teeth is most principal work parts on the disintegrating machine, and its structural behaviour is directly determining the security and the reliability of equipment overall operation.At present, " combine and adopt+the caving coal " mining type that generally adopts under the large-scale coal mine, coal seam interlayer or top, base plate produce a large amount of sheets, strip coarsegrain material, and except that coal, also having solid rocks such as a lot of spoils, white sand rock, igneous rock or even basalt etc. in these bulk materials, compression strength is about 160 ~ 250MPa.These all require disintegrating apparatus to have higher breaking strength, reliability and ease for maintenance.Conventional crushing teeth adopts monoblock cast, welding or structural shapes such as tooth cap, tooth boots to be fixed on the fluted disc seat more, and preceding two kinds of structure crushing teeths can not be changed, and must change whole breaker roll after the wearing and tearing, promptly is not easy to on-site maintenance, replacing, and operation cost is high too; The two kinds of structure crushing teeths in back can be changed, but limit by structure and connection, fixed form, in high breaking strength, severe impact load

Down, occur broken teeth often, fall tooth, problem such as attachment bolt inefficacy, seriously perplexing on-the-spot ordinary production operation.

Summary of the invention

The present invention is intended to solve broken teeth that existing crushing teeth brings because of fault of construction, falls problems such as tooth, attachment bolt inefficacy, and the replaceable crushing teeth of high strength that provides a kind of disintegrating machine that is suitable under high breaking strength, the heavy shock loads to use.

The technical scheme that the present invention solve the technical problem employing is: the replaceable crushing teeth of a kind of high strength, comprise toothholder, crushing teeth, and described crushing teeth is tapered cylindrical shape structure, and the clamp nut by its tail end is fixed on the described toothholder.

Compared with prior art, the invention has the beneficial effects as follows: simple in structure, replacing convenience, especially under the operating mode of high breaking strength, severe impact, dependable performance, can effectively reduce the operation and the maintenance cost of equipment, save the repair time, enhance productivity.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Among the figure: toothholder 1, protection plate armour 2, clamp nut 3, pin 4, crushing teeth 5, buffering flange 6, groove 7, convex limited block 8, groove 9.

The specific embodiment

Below in conjunction with drawings and Examples in detail the present invention is described in detail.

Referring to Fig. 1, the replaceable crushing teeth of the high strength that present embodiment provides, constitute by toothholder 1, protection plate armour 2, clamp nut 3, pin 4, crushing teeth 5, buffering flange 6, crushing teeth 5 is looked the uniform certain quantity of designing requirement along toothholder 1 circumferencial direction, crushing teeth 5 adopts the structural shape of tapered cylindrical shape, is fastened on the toothholder 1 by clamp nut 3 by its terminal helicitic texture.

In the present embodiment, described crushing teeth 5 is by the convex limited block 8 of its conical head bottom and the groove 7 formation anti-rotation structures of toothholder 1.

In the present embodiment, described crushing teeth 5 afterbodys are provided with groove 9 and pin 4 are housed.

By above-mentioned preferred structure, the anti-rotation of crushing teeth 5, locking and locating effect have further been improved.

In order to eliminate influences such as 5 pairs of toothholder 1 severe impact of crushing teeth cause in the course of work toothholder 1 distortion, damage, buffering flange 6 is equipped with in the joint portion that crushing teeth described in the present embodiment 5 and toothholder are 1.

In order to prevent the wear damage of toothholder 1, protection armoring 2 is housed on the outer surface of toothholder described in the present embodiment 1.

Claims (5)

1. the replaceable crushing teeth of high strength comprises toothholder, crushing teeth, it is characterized in that, described crushing teeth is tapered cylindrical shape structure, and the clamp nut by its tail end is fixed on the described toothholder.
2. the replaceable crushing teeth of high strength according to claim 1 is characterized in that, described crushing teeth constitutes anti-rotation structure by the groove that its conical head bottom has convex limited block and toothholder.
3. the replaceable crushing teeth of high strength according to claim 1 is characterized in that described crushing teeth afterbody is provided with groove and pin is housed.
4. the replaceable crushing teeth of high strength according to claim 1 and 2 is characterized in that, the buffering flange is equipped with the toothholder junction in described crushing teeth conical head bottom.
5. the replaceable crushing teeth of high strength according to claim 1 is characterized in that, the protection plate armour is housed on the described toothholder outer surface.
