Abstract

The utility model relates to a high-efficient double-shaft disintegrator. Both ends of a quill shaft (18) are respectively fixedly connected with a screen drum end housing (19) and a gearwheel (13), one end of a shaft (17) is connected with a belt pulley (10), the other end is provided with circular cutter frames (21) whose outer margins are provided with rod members (20) which are paralleled with the shaft and uniformly distributed on a circumference, a cutter head (15) is arranged between each pair of cutter frames on the rod members, and a screen drum and the cutter head (15) are achieved with retrograde rotation through the quill shaft (18), the gearwheel (13), a pinion (12) and the belt pulley (11). The utility model is especially suitable for disintegrating materials with larger moisture content, such as coal, soil, etc., having the advantages of simple structure, light weight, easy maintenance, and convenient operation.

Description

High-efficient double-shaft disintegrator

The utility model belongs to double-shaft crushing machinery field.

Common crushing mechanism has only broken function more, also has some pulverizers to have screen cloth with the control discharging-material size; But on the body bonding is often arranged when the bigger material of broken humidity, sieve aperture is also blocked easily, directly has influence on the normal use of crushing mechanism.

Even the purpose of this utility model provides and a kind ofly also is difficult for producing bonding, production efficiency height and the less particle machinery of power consumption when the bigger material of broken humidity.

The utility model is realized its purpose as follows: rotating screen drum has the sieve of paying 2, main sieve 3 and end cap 19, fixedlys connected with gear wheel 13 with end cap 19 respectively in quill 18 two ends; One end of axle 17 is fixedlyed connected with belt pulley 10, be installed with circular knife rest 21 on the other end, circular knife rest outer rim have some 17 parallel with axle, equally distributed rod member 20 connects each circular knife rest on circumference, and a cutter head 15 is all arranged between every pair of adjacent circular knife rest on the every rod member.Screen drum by quill 18, gear wheel 13, pinion 12 and belt pulley 11 and and axle 17 and cutter head 15 realize counter-rotatings.The axial location of each cutter head on rod member can be fixed with the short tube of respective length.

The cutter head of twin shaft Material disintegrator of the present utility model and screen drum counter-rotating make material be difficult to be bonded on body or the screen cloth; Because parts of fine granularity material has been paid sifts out, reduce broken burden again before material is not by hammering, reduced the function consumption.Complete machine structure is simple, and is in light weight, and easy-maintaining is very suitable to the pulverizing of materials such as broken coal, soil, and is expected to promote and other industry use.When with the 7.5KW motor, the nature coal is crushed to 10mm when following, its output can reach 4 tons/time.

Embodiment further specifies the utility model below in conjunction with accompanying drawing:

Fig. 1 is the schematic perspective view of this efficient twin shaft Material disintegrator.

Fig. 2 is the relevant position schematic diagram of each critical piece of this efficient twin shaft Material disintegrator.

Fig. 3 is the connection diagram of axle 17 and quill 18 and related components.

Rotating screen drum has the sieve of paying 2, main sieve 3 and end cap 19.One end of quill 18 and the end cap 19 of screen drum are fixedlyed connected, and the other end is fixedlyed connected with gear wheel 13.Axle 17 ends outside machine are fixedlyed connected with belt pulley 10, are contained on the other end of screen drum inner chamber and have fixedly mounted several circular knife rests 21.(three circular knife rests that external diameter is identical are arranged in the figure of present embodiment.) center line of circular knife rest and the central lines of axle 17.Circular knife rest outer rim have some 17 parallel with axle, equally distributed rod member 20 connects each circular knife rest on circumference.Every rod member all has a cutter head 15 that is slidingly connected with rod member between every pair of two adjacent circular knife rests, but cutter head distaff part freely rotates, each piece cutter head can be enclosed within on the rod member with the short tube of different length at the concrete axial location of rod member and be fixed, and cutter head is sagging naturally when static.Axle 17 and quill 18 same axle center.Gear 12 and belt pulley 11 are together with one.Belt pulley 5 is connected with 11 with belt pulley 10 respectively with 9 by belt 8.Behind starter motor 7, belt pulley 5 drives belt pulley 10 and 11 rotations, pinion 12 and belt pulley 11 rotate in the same way with speed, pinion 12 reverse rotations of 13 of gear wheels and engagement, and drive quill 18, end cap 19 and main sieve 3 bearing block 14 in, pay and sieve 2 and rotate together; Meanwhile, belt pulley 10 drives axle 17 and circular knife rest 21, rod member 20 and cutter head 15 rotate together, and direction of rotation is opposite with screen drum, and cutter head is got rid of to the vertical and intersectant centerline of its longitudinal centre line with axle 17 because of centrifugal force.After entering in the screen drum by charging aperture 1, the material that minced falls into the sieve end through a pair sieve 2, part fines earlier, the bulk materials flow is become owner of in the sieve 3 on the sieve, smashed by cutter head just in reverse rotation, down particle is with flowing out from the discharging opening 4 that is positioned at below the screen drum paying the screenings that sifts out for sieve, and oversize continues fragmentation.Material disintegrator through 14 of bearing blocks on support 6.Screen drum has protective cover 16 outward.

Claims

1, a kind of efficient twin shaft Material disintegrator, motor, sieve, axle and cutter head are arranged, it is characterized in that rotating screen drum has the sieve of paying (2), main sieve (3) and end cap (19), fixedly connected with gear wheel (13) with end cap (19) respectively in quill (18) two ends, one end of axle (17) is fixedlyed connected with belt pulley (10), be installed with circular knife rest (21) on the other end, circular knife rest outer rim have some 17 parallel with axle, equally distributed rod member (20) connects each circular knife rest on circumference, and a cutter head (15) is all arranged between every pair of adjacent circular knife rest on the every rod member; Screen drum by quill (18), gear wheel (13), pinion (12) and belt pulley (11) and and axle (17), cutter head (15) realization counter-rotating.
