Abstract
The invention discloses a double-roll impact crusher, which consists of a shell, a feeding hopper, a drive roll, an impact roll and a transmission device, wherein the shell consists of an upper shell and a lower shell; the drive roll and the impact roll which performs reciprocating vibration from left to right are arranged in parallel on split positions in the shell; the lower shell is directly connected with a foundation; and the upper end of the upper shell is connected with the feeding hopper. The double-roll impact crusher is characterized in that the drive roll is supported on a straight shaft; the straight shaft is arranged on a bearing pedestal on both ends, and driven to rotate at a low speed by a motor through a speed reducer; the impact roll is supported by an eccentric shaft of which both ends are arranged on the bearing pedestal, and is arranged on an eccentric part through a pair of bearings; the eccentric shaft is directly driven to rotate at a high speed by the motor; and eccentric blocks are connected with both ends of the eccentric part of the eccentric shaft. The double-roll impact crusher has the advantages of low energy consumption, high efficiency, good crushing effect, simple structure and no vibration on a machine body.
Description
Technical field
The present invention relates to a kind of double-roll crusher, belong to crushing mechanism, especially a kind of double-roller impact crusher.
Background technology
Mostly the double-roll crusher that extensively adopts in the current production is two breaker rolls are installed in body side by side, and by synchromesh gear, perhaps two motors obtains the rotation in opposite directions of two breaker rolls.The fragmentation of material is to finish by the extruding of breaker roll, needs bigger extruding force, and the transmission moment of torsion is big, power consumption is high, crushing efficiency is low, and the transmission mechanism volume is also relatively large.Two roller vibro-crushers propose at the problems referred to above, and it utilizes vibratory impulse and shearing mechanism broken material, and energy consumption is low, efficient is high.But two roller vibro-crusher complex structures, that spring system need be adjusted parameter is more, and discharging-material size can not strict control, and body itself can the generation judder simultaneously, and vibration insulating system that need be special is to reduce the disturbance to the basis.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned the deficiencies in the prior art, provide that a kind of energy consumption is low, efficient is high, crushing effect is good, simple in structure, the vibrationless double-roller impact crusher of fuselage, it is applicable to the fragmentation of crisp rigid material.
Implementer's case of the present invention is: a kind of double-roller impact crusher, form by casing, feed hopper, drive roll, impact roll and transmission device etc.; Described casing is made up of upper casing and lower casing, and inherent split place of casing is arranged side by side the impact roll of drive roll and left and right sides double vibrations, and lower casing directly connects in the basis, and the upper casing upper end is connected with feed hopper; It is characterized in that: drive roll is supported on the d-axis, and d-axis is installed on the two end axles bearing, is driven by decelerator by motor, slowly runs; Impact roll is supported by eccentric shaft, and the eccentric shaft two ends are installed on the bearing block, and impact roll then is installed in eccentric part by pair of bearings, and eccentric shaft is directly driven by motor, high speed rotating.Be connected with eccentric block at eccentric shaft eccentric part two ends, the out-of-balance force that is produced in order to balance eccentric shaft and impact roll.
Described drive roll and impact roll are made up of wheel hub and crushing shell, and crushing shell is connected on the wheel hub with dormant bolt.
The invention has the beneficial effects as follows: (1) crusher chamber is made up of drive roll and impact roll, and drive roll is mainly used to force feeding, and impact roll is mainly used to broken material, utilize impact principle to carry out fragmentation, the compound action that material is impacted and shears, energy consumption is low, the efficient height; (2) utilize the eccentric shaft of high speed rotating realize impact roll left and right sides double vibrations impact material, amplitude constant has guaranteed discharging-material size, out-of-balance force is offset by eccentric block, fuselage body does not show vibration; (3) impact roll is free to rotate, and drive roll is by the frictional force effect of material, and impact roll is in rolling state, and it is few to slide relatively, the wearing and tearing that alleviated breaker plate surfaces; (4) crushing shell wearing and tearing back is replaceable, and the crushing shell of different-thickness can adapt to different grain size and require: (5) the present invention is simple in structure, is easy to make installation and maintenance, is suitable for crisp rigid material fragmentation especially.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in further detail.
Fig. 1 is a front view of the present invention;
Fig. 2 is a vertical view of the present invention.
Among the figure: 1,7. motor; 2. decelerator; 3,8. shaft coupling; 4,9. bearing block; 5. drive roll; 6. lower casing; 10. eccentric block; 11. bearing; 12. crushing shell; 13. wheel hub; 14. eccentric shaft; 15. impact roll; 16. upper casing; 17. feed hopper.
The specific embodiment
As shown in Figure 1 and Figure 2: the utility model is directly installed on the basis by lower casing 6, and bearing block 4,9 is connected as a single entity by gusset and lower casing 6.Drive roll 5 and impact roll 15 are arranged in same plane parallel, are supported by bearing block 4 and bearing block 9 respectively.Upper casing 16 and lower casing 6 connect by spiral, are connected with feed hopper 17 on upper casing 16 tops, and material is delivered to crusher chamber between drive roll 5 and the impact roll 15.
Described drive roll 5 is cemented on the d-axis by the key connection, and motor 1 drives drive rolls 5 by decelerator 2, shaft coupling 3 and slowly runs; Described impact roll 15 is by pair of bearings 11, and kink directly drives eccentric shaft by motor 7 by shaft coupling 8 and rotates at a high speed in the eccentric part of eccentric shaft 14, and impact roll itself is free to rotate.
A pair of eccentric block 10 is installed at described eccentric shaft 14 eccentric segment two ends, and both pass through key connecting.The eccentric direction of eccentric block 10 is opposite with eccentric shaft 14 eccentric shaft directions, and eccentric throw is bigger, and the out-of-balance force that out-of-balance force that eccentric block 10 produces in the rotation process and impact roll 15 produce is offset.
Described drive roll 5 and impact roll 15 are made up of wheel hub and crushing shell.Impact roll 5 has been installed 6 crushing shells 12 on its wheel hub 13, crushing shell 12 is through Wear-resistant Treatment.Change crushing shell thickness in the certain limit, can obtain varigrained product.
Described bearing block 4,9 is split up and down, and is convenient for installation and maintenance.
