Description

A kind of soil breaking machine

The utility model relates to a kind of disintegrating machine, especially a kind of disintegrating machine that is applicable to soft materials such as soil.

High-grade highway and heavy construction facility need be stablized processing to ground, are powdery and fine granularity by code requirement with soil breaking promptly, mix grinding compacting with additives such as lime then.The disintegrating machine that uses mostly is flyball breaking (impacting principle) at present, as the multiclass jaw crusher; Single transfer roller or two transfer roller squash type (coming the attrition crushing principle) by the gap that changes in the soil movement, as all kinds of flour mills, this class disintegrating machine production efficiency is low, complex structure, crushing force are little, and is not suitable for moisture higher clayed soil; Also using in engineering has multi-stage screening equipment, promptly by screening bulk soil material is pulverized once more by special equipment, is not suitable for clayed soil equally, and complex structure, and production efficiency does not satisfy the large-engineering needs.

The purpose of this utility model be to provide a kind of simple in structure, crushing force is strong, production efficiency is high, applicable to the disintegrating machine of various soil, to overcome above-mentioned the deficiencies in the prior art.

The purpose of this utility model can realize by following structure:

A kind of soil breaking machine, by feed hopper, discharge bucket, tooth drum and drive unit are formed, and are unified into body by its end limit by bolt at horizontal integration face into and out of hopper.The tooth drum is that the Cylinder of closed at both ends, two ends have central shaft to be installed in feed hopper, discharge bucket horizontal integration face two ends by bearing, and wherein an end central shaft and drive unit connect, and the pectination cutter tooth has been staggered on post surface, tooth drum garden; The discharge bucket half garden shape bar grizzl(e)y that paralleled to the axis is fixed on the discharge bucket two ends; Feed hopper antetheca lower end is 50-70 ° of inclination angle at water surface faying face, and feed hopper rear wall lower end is 45-70 ° of inclination angle at tooth drum top, and the back operating room of semicircle type is arranged between feed hopper rear wall lower end and the horizontal integration face.

Place on the Working gantry during the utility model work, soil adds feed hopper by top, the tooth drum drives direction shown in the arrow of lower edge at drive unit and rotates at a high speed, and the utility model tooth drum cutter tooth top best effort linear velocity is 6～9m/s, and soil moves downward under deadweight and cutter tooth drive.Because the feed hopper antetheca tilts to install, the space of soil is diminished from top to bottom gradually, be collected at a narrow and small fracture area, in the cutter tooth high-speed cutting, bounce, carry out first order fragmentation under the squeezing action, under the drive of cutter tooth, enter the screening district subsequently, soft material such as soil passes through extruding between cutter tooth and bar grizzl(e)y, draw mill to carry out second level fragmentation, bar grizzl(e)y spacing and cutter tooth and bar grizzl(e)y, gap, back operating room, should satisfy the grain size of code requirement, the qualified particle that meets code requirement is discharged from discharging opening by bar grizzl(e)y, and a small amount of defective particle carries out second circulation by operating room and new adding soil under cutter tooth drives broken.

Realize that the drive unit of the utility model purpose can be the belt gear or the gear drive of driven by motor, for adapting to different operating modes, the optimal drive device is a hydraulic motor arrangement.Hydraulic motor arrangement can be the radial plunger low speed high torque hydraulic motor or the high speed piston motor adds the planetary reducer composition.Form vault on feed hopper top for preventing to add soil, the utility model can add rapping or the leaf slurry revolves arch breaking apparatus such as drum-type at feed hopper.

The utlity model has following advantage in sum:

1, tooth drum cutter tooth high-speed cutting, bounce, push and utilize between cutter tooth and the bar grizzl(e)y and push, draw the composite breaking operation principle of mill, can broken various soil, comprise the clayed soil that broken moisture content is higher, even fragment of brick, stone, the production efficiency height, output per hour can reach hundreds of tons.

2, reliable operation simple in structure, it is stressed rationally that the tooth drum is gone up staggered cutter tooth, and it is good to cut the even fine and closely woven fragmentation quality of soil.

3, adopt fluid pressure drive device varying duty ability strong, band carrying power is very big, and breaking capacity is strong.
