Description

A kind of small-sized waste asphalt mixture disintegrating machine

Technical field

The utility model relates to the device of crushing operation, particularly a kind of small-sized waste asphalt mixture disintegrating machine.

Background technology

Along with the continuous progress of current urban construction, the application of disintegrating machine more and more widely, it is various in style, function is different, but there is following defective mostly in the disintegrating machine on the existing market:

(1) tup that is installed in the disintegrating machine on the hammer dish adopts overall structure, must change whole tup if tup damages;

(2) rotor speed of disintegrating machine is constant, and the particle size after cracking of material can not be adjusted as required, can not be suitable for different materials;

(3) the discharging opening phenomenon that easily gets congestion, and dust is bigger;

(4) the mechanical movement noise is big, is unfavorable for laboratory test;

(5) mechanical volume is bigger, makes troubles to mobile operational process.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of small-sized waste asphalt mixture disintegrating machine.

The technical solution of the utility model is to solve like this: a kind of small-sized waste asphalt mixture disintegrating machine comprises engine, driver and a crusher chamber, the top of crusher chamber is connected with charge door, its special character is that crusher chamber central authorities are connected with a main shaft, main shaft is connected with the hammer dish, one end of hammerhead jib is connected with the hammer dish, the other end of hammerhead jib is connected with tup, quartering hammer is by tup, hammerhead jib is formed, the end housing junction is provided with sealing ring on the crusher chamber, the crusher chamber bottom is provided with discharging opening, the discharging opening below is provided with drawing mechanism, the right side enclosure interior of crusher chamber is equipped with driver, engine, outer setting has power supply indicator, the start button, the shutdown button, the below of start button is provided with battery main switch, and the bottom support bracket of crusher chamber is connected with ground by ground nail Luo hole.

It is a kind of simple in structure that the utility model provides, easy to maintenance, to reaching the granularity effect of milling machine milling after the fragmentation of bulk waste asphalt mixture, and adjust different big or small compound particle size after cracking by dismountable tup, this disintegrating machine use cost is low, and noise is little, and discharging is convenient, dust is little, is applicable to laboratory test.

The utility model compared with prior art has following advantage:

(1) because engine separates with crusher chamber, and easy to maintenance, quartering hammer, hammerhead jib all adopt nut to be connected with the hammer dish, the dismounting aspect can reach different particle size after cracking by the quantity of adjusting quartering hammer.

(2) engine drive driver can electrodeless rotating speed, the rotating speed of its main shaft can electrodelessly change, and makes the linear velocity of tup adjustable, can adapt to the variation and the requirement of satisfying different particle size after cracking of material like this.

(3) tup of disintegrating machine adopts new structure, helps the fragmentation of material.

(4) discharging opening adopts transmitting device, has avoided the jam of discharging opening, and dust is little.

Extensively apply to the crushing operation of numerous industries such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry, be used in particular for the crushing operation in highway regeneration field.

The specific embodiment

Accompanying drawing is a specific embodiment of the utility model

Below in conjunction with accompanying drawing content of the present utility model is described further:

Shown in Fig. 1～3, a kind of small-sized waste asphalt mixture disintegrating machine comprises engine, driver and a crusher chamber 5.The top of crusher chamber 5 is connected with charge door 1, crusher chamber 5 central authorities are connected with a main shaft 3, main shaft 3 is connected with hammer dish 15, one end of hammerhead jib 11 is connected with hammer dish 15, the other end of hammerhead jib 11 is connected with tup 12, quartering hammer 4 is by tup 12, hammerhead jib 11 is formed, quartering hammer 4 is 30 ° of intersection rotations each other in the high speed rotary course of main shaft 3, can adapt to the variation and the requirement of satisfying different particle size after cracking of material, the end housing junction is provided with sealing ring 9 reinforcings on the crusher chamber 5, crusher chamber 5 bottoms are provided with discharging opening 14, discharging opening 14 belows are provided with drawing mechanism 2, the right side enclosure interior of crusher chamber 5 is equipped with driver, engine, outer setting has power supply indicator 6, start button 7, shutdown button 8, the below of start button 7 is provided with battery main switch 13, when power-on master switch 13, power supply indicator 6 is bright, pressing start button 7 engines drive driver subsequently starts working, driver drives the electrodeless rotating speed of main shaft, finish fragmentation, the bottom support bracket 16 of crusher chamber 5 is connected with ground by ground nail Luo hole 10, when quitting work by the button 8 that shuts down.

Adopt nut to be connected between described tup 12, hammerhead jib 11 and the hammer dish 15, tup 12 be shaped as taper or cylindrical or convex.

Described main shaft 3 is electrodeless rotating speed, and the linear velocity of its tup is adjustable.

At least be connected with 8 tups on the described hammer dish 15.

Operation principle

The asphalt piece of excavating when bituminous paving enters crusher chamber when carrying out fragmentation from charge door, the quartering hammer that meets intersection rotation is at a high speed hit fragmentation, and the acquisition energy rushes at the inwall of crusher chamber, the inwall of crusher chamber is rough curved surface, material is run into material in the backlash by its curved surface after rebounding, broken by mutual bump therebetween, finish the coarse crushing process, because engine drives the electrodeless rotating speed of driver, the rotating speed of its main shaft can electrodelessly be changed, and then the linear velocity of tup is adjustable, finish the requirement of different particle size after cracking, along with constantly dosing of material, the continuous accumulation of the material in the crusher chamber makes the inwall of crusher chamber and the distance around the quartering hammer diminish gradually, and material is subjected to impact grinding or attrition crushing once more, before has been repeated broken material and has been extruded landing to the conveyer belt of drawing mechanism, be transported to discharging opening by conveyer belt, finish whole shattering process.

Asphalt after the fragmentation has suitable grating, uses with surface layer and basic unit's regeneration as bituminous paving, has both protected environment, has good economic and social benefits again.
