Abstract
The present invention relates to a double-roll crusher which comprises a frame, a pedestal, roll shafts, rollers and a transmission part. The roll shafts are a high-speed roll shaft and a low-speed roll shaft which are respectively provided with a roller, the low-speed roller is a smooth roller, a plurality of cutter blades are arranged on the high-speed roller, the two rollers relatively rotate at different rotary speed, and the diameter of the low-speed roller is larger than that of the high-speed roller. The present invention not only can crush materials with medium hardness, but also is particularly suitable for crushing clay, and the present invention can effectively prevent materials from sticking on roller surfaces.
Description
Technical field
The present invention relates to a kind of kibbler roll, particularly relate to a kind of double-roll crusher of suitable broken clay class material.
Background technology
Kibbler roll can be divided into single roller, two roller and multiple roll crusher by the roller quantity difference that adopts.The frictional force of utilizing roll surface is the material fracture area of nipping, and makes material bear extruding or splitting and is broken.Be applicable to medium-hard material, as coarse crushings such as ore, rock, in operation broken or in small, broken bits.
Existing double-roll crusher adopts two smooth rolls or double teeth roller structure.The speed of two rollers is identical, and roller diameter equates, drives two rollers by motor through V belt and does the relative direction rotation, finishes the material fragmentation.If adopt the disintegrating machine of this structure; when broken clay or frozen soil class material; material is extruded because of the extruding moisture that is subjected to roller; material regular meeting adheres to the surface of roller; need constantly remove the material that adheres on the roller with scraper plate; have a strong impact on crushing efficiency, otherwise crushing operation can't be carried out.
Summary of the invention
The technical problem that the present invention solves provides a kind of double-roll crusher, and it not only can broken medium-hard material, especially is fit to broken clay class material, prevents that effectively material from adhering to the surface of roller.
For solving the problems of the technologies described above, double-roll crusher of the present invention comprises frame, base, roll shaft, roller, running part, and wherein said roll shaft is two on high speed roll shaft and a low speed roll shaft, the high speed roll shaft is fixed on the frame, and the low speed roll shaft is installed on the rack slide; Be separately installed with roller on these two roll shafts, the low speed roller is a smooth roll, is equipped with many blade on the high speed roller; Two rollers relatively rotate with different rotating speeds; Described low speed roller diameter is greater than the high speed roller diameter.
The rotating ratio of described two roll shafts is: 1: 10～1: 12, the diameter ratio of described two rollers was: 1: 1.5～1: 2, the knife number of installing on the described high speed roller can be: 8～12.
Because adopt said structure, two rollers relatively rotate with different rotating speeds, form crusher chamber, rely on two rollers rotate relatively generation extruding, tear with shear action and come broken material.Enter when material after the crusher chamber of machine, be subjected to the engagement force feeding of low speed roller and the shear action of high speed roller, be fractured into fragment and pass through between two rollers, adhere to roller surface when effectively avoiding broken clay class material, crushing efficiency is obviously improved.

Fig. 2 is the cutaway view of high speed roller of the present invention and roll shaft structure;
Fig. 3 is the cutaway view of low speed roller of the present invention and roll shaft structure.
The specific embodiment
As shown in Figure 1, double-roll crusher of the present invention comprises base, frame, roll shaft, roller, running part.This base 1 is a rectangular body that is welded into I-steel; Frame 2 is the housings that are welded into by steel plate, and this frame 2 is fixed by bolts to the middle part of base 1, and frame 2 relative two sides form slideway 3 with upper and lower being symmetrically welded of steel plate.
Described roll shaft is divided into high speed roll shaft 4 and low speed roll shaft 5.The rotating ratio of two roll shafts is 1: 10～1: 12.Referring to shown in Figure 2, high speed roll shaft 4 is a long multidiameter, is provided with keyway 16 in the middle part of this high speed roll shaft 4.Near a side of this keyway 16, be provided with round boss 17 along the circumference of high speed roll shaft 4.Relative with this boss 17, at the opposite side of axle 4, be provided with one section screw thread near the position of being good for groove 16.The both sides of this high speed roll shaft 4 are equipped with bearing 18, and this bearing 18 can adopt double row cylindrical roller bearing, is fixed on the frame 2 by bearing block 19.End at high speed roll shaft 4 also is provided with belt pulley 20.Also be long multidiameter referring again to Fig. 3 low speed roll shaft 5, be provided with keyway 21 in the middle part of this low speed roll shaft 5, be positioned near the both sides of this keyway 21, be provided with one section screw thread separately.The both sides of this low speed roll shaft 5 are equipped with bearing 22, and this bearing 22 can adopt double row cylindrical roller bearing, are installed on the rack slide 3 by bearing block 23, and spring 6 is equipped with at its rear portion, can guarantee that roller has enough crushing forces when work.End at low speed roll shaft 5 also is provided with belt pulley 24.
Be separately installed with roller on two roll shafts.Wherein, low speed roller 7 is the smooth roll tube, casts with potassium steel to process from strand.The relative both sides of low speed roller 7 inwalls correspondence is provided with round platform 25, is provided with sipes 26 in this inwall middle part.Position between sipes 26 and round platform 25 forms taper seat wide outside and narrow inside 27.Wheel hub 14 and sector disk 15 (showing as Fig. 3) are installed in this low speed roller 7.Described wheel hub 14 is made up of wheel shaft 30, big trochal disc 31, small trochal disc 32.Large and small wheel disc 31,32 side end faces are taper seat, and suitable with the taper seat 27 of low speed roller 7 inwalls.Big trochal disc 31 is along the even a plurality of round open-works 33 that distribute of card.Be provided with the axis hole 28 that matches with low speed roll shaft 5 in the middle of this wheel hub 14 end faces, and a side of this axis hole 28 be provided with low speed roll shaft 5 on the keyway that matches of keyway 21.The middle part that is positioned at this axis hole 28 also is provided with sipes 29.Described sector disk 15 is a disc, in the middle of it is and the suitable conical bore of described small trochal disc 32 side taper seats, also is provided with a plurality of on the card and big trochal disc 31 circle open-works 33 corresponding round open-works 34.Pass round open-work 33 on the big trochal disc 31 and the round open-work 34 on the sector disk 15 with bolt 35, two ends are installed together low speed roller 7, wheel hub 14, sector disk 15 with nut.The axis hole 28 that low speed roll shaft 5 passes wheel hub 14 links together the two by key, and two ends are with round nut 37 locking, and can be in axial trim locations, so as with high speed roll shaft complete matching, low speed roller 7 is fixed on the low speed roll shaft 5.
