Abstract
The utility model discloses a breaker jump bit, can dismantle fixed connection and be used for hitting the tup of material including the hammer handle with the hammer handle, surface integrative casting shaping in hammer handle top is provided with the enhancement layer, and the tup includes tup body and embedment, and the tup is the cast steel body, and the embedment be the high chromium cast iron alloy body, and high chromium cast iron alloy personally experiences sth. Part of the body to being provided with the porous structure who is used for forming the permeability hole that steel -cast molten steel permeates, the hammer handle can be dismantled to be connected with the tup and fix, when hammer handle or the damage of the single position of tup, can change alone it, reduction of use cost, additionally, set up the enhancement layer at hammer handle top surface around the circumference, the wearability and the crack resistance of reinforcing hammer handle, and simultaneously, set up the embedment through embedding in the tup, when the molten steel of the cast steel body is cast, the molten steel is around the embedment and in permeating the permeability hole, it forms strong mechanical interlocking to make between the cast steel body and embedment, thereby obtaining high connection strength, thereby improve the holistic structural strength of wear -resisting hammer, the wearability.
Description
Technical field
The utility model relates to Mechanical Crushing field, particularly a kind of disintegrating machine jump bit.
Background technology
Quartering hammer is the core component of disintegrating machine, be mainly used in break mined material raw material, cracking hammer head High Rotation Speed in disintegrating machine runs, and between raw mineral materials in impact several times impact friction process, cracking hammer head head is made to be diminished by progressively wearing and tearing and lose efficacy and scrap, length in service life due to cracking hammer head directly affects the fragmentation quality of material and production efficiency and cost, need frequently more to renew tup to meet the needs of production, so broken industry is constantly making great efforts the tup manufacturing the high life always.And existing tup mostly is integrative-structure, comprise integrated tup body and hammer handle portion, when tup body damages or hammer handle portion damages, all need overall tup to change, use cost is higher.
Therefore, need to improve existing disintegrating machine hammer, make its structural strength high, long service life.
Utility model content
In view of this, the utility model provides a kind of disintegrating machine jump bit, and its structural strength is high, and anti-high speed impact ability is strong, long service life.
Disintegrating machine jump bit of the present utility model, comprise the hammer handle that is fixed on disintegrating machine bearing pin and be detachably fixedly connected with hammer handle and tup for hitting material, the outer surface one cast molding of described hammer handle top is provided with enhancement layer, described tup comprises tup body and two embeddings and is arranged on insert in tup, described tup is cast steel body, described insert is high-chromium cast iron alloy body, and described high-chromium cast iron alloy body is the loose structure of the permeability hole of the infiltration of molten steel be provided with for the formation of cast steel.
Further, the described permeability hole on insert described in each includes fluid inlet and fluid issuing, and permeability hole forms alveolate texture jointly.
Further, tup is the cast steel body be made up of high manganese steel material.
Further, hammer handle is provided with suppending hole, suppending hole is 300-320mm to tup end distance.
Further, suppending hole exradius is 70mm.
Further, enhancement layer is that rich chromium cast iron is made.
Further, the cross section of tup is sector structure, and two insert one_to_one corresponding tup two sides also be arranged in parallel.
The beneficial effects of the utility model: disintegrating machine jump bit of the present utility model, hammer handle and tup removably connect fixing, when hammer handle or the single position of tup are damaged, can change separately it, reduce use cost, in addition, on hammer handle top, outer surface circumferentially arranges enhancement layer, strengthen wearability and the crack resistance of hammer handle, simultaneously, by being embedded at tup, insert is set, it insert is loose structure, when the molten steel of cast steel body is cast, molten steel is around insert and infiltrate through in permeability hole, make to be formed between cast steel body and insert mechanical interlocked by force, bonding strength is high, thus improve the structural strength of Wear resisting hammer entirety, wearability and anti-high-speed impact property, and, make the utility model wear rate low, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model lateral plan;
Fig. 3 is the insert schematic cross-section in the utility model.
Detailed description of the invention
