The utility model discloses the hammer leaf head and the hammer leaf both sides wing are widened, are thickeied, have increased the wearability of hammer leaf, its hammer leaf afterbody is circular, has reduced the resistance of the rotatory in -process of hammer leaf, the abrasion durability of hammer leaf with hammer leaf axle contact segment has been improved.

Description

A kind of abrasion-proof crusher hammer leaf

(1) technical field

This utility model is related to a kind of abrasion-proof crusher hammer leaf, belongs to agriculture and forestry machinery manufacture field.

(2) background technology

Per the process of season crop harvesting and the straw after woods fruit beta pruning and branch, extensive concern both at home and abroad is caused, Burn and also pollute environment in field is both uneconomical, it is domestic and in the world many countries have all formulated taboo combustion regulation.Jing is studied, Concentrate that to crush be one of the best method for processing these straws, rice husk and branch, can not only do paper pulp after crushing but also fertilizer etc. can be worked as.

But, in straw, branch, the crushing process of rice husk, the degree of wear for reducing the hammer leaf of pulverizer is to reduce crushing One of the most key problem of cost.The most material of hammer millses of current enterprise application is made at layer for 65Mn or 35# steel Reason, after this hammer leaf is using a period of time, layer is easy to fall off, the production and processing of injury device and impact product (such as papermaking)；Hammer The abrasion of piece both wings is very fast, and service life is shorter, is that every set hammer leaf (145/set, 15-18 units/piece) is only produced about with Production rate 150 tons of powder, crush production cost and remain high；The Kong Weiyi small sircle holes (φ 10mm) (see photo) of hammer leaf middle and lower part, reduce The venturi effect that hammer leaf operation process is produced is poor, causes hammer leaf operation unstability, and causes the material skewness of dnockout intracavity, causes In this set hammer leaf, the degree of wear of hammer leaf has serious difference, greatly have impact on production.

（Three）The content of the invention

It is on the basis of existing hammer leaf to overcome drawbacks described above, this utility model to provide a kind of abrasion-proof crusher hammer leaf On, its structure is improved, there is provided a kind of stable working, high abrasion, do not fall off, processing technology is advanced, it is with low cost and The New type straw grinding machine hammer leaf of high service life.

The technical scheme in the invention for solving the technical problem is：

A kind of hammer millses, are made up of the hammer leaf head, the flank of hammer leaf two and the hammer leaf afterbody that are connected as an entirety.

Hammer leaf head is rectangle；Hammer leaf afterbody is in circular arc；And hammer leaf head width is slightly larger than hammer leaf afterbody；Hammer leaf head It is provided with hammer leaf head perforate；The perforate of hammer leaf head is in Long Circle, its wide and long respectively 10mm and 30mm；Hammer leaf afterbody is provided with to be worn Axis hole, the center of circle for wearing the middle part perforate of axis hole, the perforate of hammer leaf head and hammer leaf is located on straight line；

Hammer leaf head lower limb is 2/3rds of overall hammer leaf height with the distance of the flank upper end of hammer leaf two；Hammer leaf both sides The width of the wing is 10mm；The height of hammer leaf head is 10mm；Will the upper and lower surface of the flank of hammer leaf two and hammer leaf head do simultaneously Identical thickening is processed；The flank of hammer leaf two distinguishes outwardly convex with the upper and lower surface of hammer leaf head.

This utility model compared with existing hammer leaf, with advantages below：

1st, hammer leaf head and the flank of hammer leaf two are widened, are thickeied, and increased the wearability of hammer leaf.

2nd, hammer leaf middle part perforate, reduces and produce in hammer leaf rotary course vortex, is beneficial to each powder of pulverizer dnockout intracavity Particle reasonable layout.

3rd, hammer leaf afterbody is circle, reduces the resistance in hammer leaf rotary course.

4th, hammer leaf afterbody wears axis hole region and does not carry out intensive treatment, to improve the wear-resisting longevity of hammer leaf and hammer slice axis contact portion Life.

In figure：1st, hammer leaf head 2, hammer leaf head perforate 3, the flank 4, hammer leaf of hammer leaf two middle part perforate 5, wear axis hole 6th, hammer leaf afterbody

(5) specific embodiment

This utility model is further described in conjunction with accompanying drawing, as shown in figure 1, opening including hammer leaf head 1, hammer leaf head Hole 2, the middle part perforate 4 of the flank 3, hammer leaf of hammer leaf two, hammer leaf afterbody wear axis hole 5, hammer leaf afterbody 6.Material used in the present invention can High-quality high-abrasive material is taken to cast, then using C, N, B RE co-permeating processing method gained.The hammer leaf afterbody 6 is by wearing axis hole 5 It is fixed on existing pulverizer in the rotary shaft of dnockout intracavity；A hammer leaf is fixed at interval of certain distance in rotary shaft, is then led to The high speed for crossing rotary shaft rotarily drives the rotation of hammer leaf；According to hammer leaf concrete condition when in use, it is found that existing hammer leaf makes Used time, the head and middle and lower part both wings serious wear of hammer leaf, therefore hammer leaf head 1 and middle and lower part are changed in the present invention Enter, this region is thickeied；Existing hammer leaf, because of the dnockout chamber intracavity gas flowing of pulverizer, causes hammer leaf in high-speed rotation Rotation is unstable, therefore hammer leaf head is increased into an oblong hammer leaf head perforate 2, to reduce impact of the air-swirl to hammer leaf； For reducing energy consumption, cost-effective, hammer leaf afterbody 6 is designed as into circle, reduces the air drag of hammer leaf rotary course.

The most material of hammer millses applied on current market is that 65Mn or 35# steel makees layer process, and this hammer leaf makes After a period of time, layer is easy to fall off, the production and processing of injury device and impact product (such as papermaking), and service life is shorter, It is that every set hammer leaf (145/set, 15-18 units/piece) only produces about 150 tons of powder with Production rate, crushes production cost and occupy height not Under, and bring inconvenience to production.

Jing is every set hammer leaf (145/set, 21 yuan/piece) with Production rate using checking, this kind of Novel hammer service life About 500 tons of powder of production, often cover yield than as many as 3 times of raising in the past, and often produce 1000 tons of powder, just save fund 11310 yuan, and this hammer leaf surface is without any welding coat, without any metal derby obscission in production process, greatly reduces powder Broken production cost, facilitates production.

This utility model performance advantage significantly, is embodied as：1st, traditional hammer leaf has been carried out being improved in structure, It is more suitable for the use environment of hammer leaf, is embodied in：By the way that hammer leaf afterbody 6 is designed as into circle and hammer leaf head perforate is increased 2, the course of work is steady；Hammer leaf dnockout is uniform；Each hammer leaf degree of wear is impartial in often covering；Hammer leaf service life extends；Hammer slice axis Service life prolongation etc..2nd, cost of manufacture is cheap.
