Abstract

The utility model discloses a kind of Novel hammer rusher tup, it includes that hammer body, gusset and lasso, described lasso are three, and is distributed on circumference；Described hammer body is with potassium steel as matrix, integral with three lasso castingins respectively；Described hammer end facial contour is circular, and the center of circle of this circle is concentric with lasso；Three hammer bodies, also with potassium steel as matrix, are connected as a single entity by described gusset, and the outline of described gusset is circular curve, and tangent with hammer body.The phenomenon of hammer body fracture will can be prevented effectively from lasso castingin to potassium steel matrix；Three lassos are uniform, and each lasso when for reversible hammer mill, Ore all can be hit in hammer body both sides as pin-and-hole and rotor block hinge, can quite extend six times, greatly reduce use cost, improve economic benefit its service life.

Description

A kind of Novel hammer rusher tup

Technical field

This utility model relates to a kind of Novel hammer rusher tup.

Background technology

Reversible hammer mill be fine stone lime stone in the industrial departments such as metallurgy, building materials, chemical industry and water power, coal or other One of capital equipment of the following brittle material of medium hardness.Have broken than big, production capacity is high, structure is advanced, dependable performance, Stable working, energy consumption be low and the feature such as epigranular.Hammer mill divides reversible and unidirectional type two kinds, and reversible hammer breaks The rotor of broken machine is reversible, is generally used in small, broken bits；The rotor of unidirectional type hammer mill is irreversible, broken in being generally used for.Machine In use for some time, the one side of tup work has worn out, and the liner plate of rotor side and grid section also have certain abrasion, this Time can stop a motor reversal connection, at this moment rotor reverses, and the unworn one side of tup reforms into work surface, and utilizes opposite side Unworn grid section and liner plate.Tup is installed can use on two sides, reduces the set-up time, improve work efficiency.

Currently available technology hammer head of hammer crusher one end is pin-and-hole, on the hinged bearing pin being suspended on rotor block, and the other end Ore is hit, when tup may wear to a certain degree, i.e. entirety is scrapped, and stock utilization is low as tup.

Utility model content

This utility model is in order to solve the problems referred to above, it is provided that a kind of Novel hammer rusher tup.

This utility model solves its technical problem and be the technical scheme is that a kind of Novel hammer rusher tup, bag Including hammer body, gusset and lasso, described lasso is three, and is distributed on circumference；Described hammer body with potassium steel as matrix, respectively with Three lasso castingins are integral；Described hammer end facial contour is circular, and the center of circle of this circle is concentric with lasso；Described gusset also with Potassium steel is matrix, is connected as a single entity by three hammer bodies, and the outline of described gusset is circular curve, and tangent with hammer body；Described The thickness of gusset is less than the thickness of hammer body.

Further, the thickness of described hammer body is equal to the length of lasso.

Further, the wall thickness of described lasso is between 10～20mm.

The beneficial effects of the utility model are: owing to hammer body uses cylindrical structure, make the impulsive force acting on hammer body Position can reduce vibration and noise essentially by being equivalent to the lasso center of circle of center of impact, and Extending Rotor bearing uses the longevity Life；The phenomenon of hammer body fracture will can be prevented effectively from lasso castingin to potassium steel matrix；Three lassos are uniform, each lasso Can be as pin-and-hole and rotor block hinge, when for reversible hammer mill, Ore all can be hit in hammer body both sides, and it makes Quite extend six times with the life-span, greatly reduce use cost, improve economic benefit.

Accompanying drawing explanation

The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.

Fig. 1 is this utility model structural representation；

Fig. 2 is the sectional view of Figure 1A-A.

Detailed description of the invention

As depicted in figs. 1 and 2, a kind of Novel hammer rusher tup, including hammer body 1, gusset 3 and lasso 2, described lasso 2 is three, and is distributed on circumference；Described hammer body 1 is with potassium steel as matrix, integral with three lasso 3 castingins respectively；Described Hammer body 1 end profile is circular, and the center of circle of this circle is concentric with lasso 2；Described gusset 3 is also with potassium steel as matrix, by three Hammer body 1 is connected as a single entity, and the outline of described gusset 3 is circular curve, and tangent with hammer body 1.

For the ease of casting, the thickness of described gusset 3 is less than the thickness of hammer body 1.

The thickness of described hammer body is equal to the length of lasso.

For proof strength requirement, the wall thickness of described lasso is between 10～20mm.

Hammer body 1 selects hardness high, has again the high manganese steel material of certain wearability, the chemical composition of its design potassium steel Mass fraction: 1.16%～1.27%C, 13.06%～14.28%Mn, 0.52%～0.84%Si, 1.91%～2.43% Cr, 0.03%～0.05%S, 0.04%～0.06%P, 0.19%～0.25%Re, 80.82%～83.09%Fe.

Landing component is that intensity is high, and the preferable medium carbon steel of plasticity, toughness will not rupture under impact force action.

Putting in evaporative pattern by lasso 2, pour into a mould potassium steel solution, making both is metallurgical binding.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model Within the scope of protecting.

Claims
