Abstract

The invention discloses a rotor of a reversible crusher. The rotor comprises a main shaft (11), a hammer disk (33) with pin holes (22), hammer handles (44), hammer heads (55) and connecting pins. The rotor is characterized in that the rotor also comprises a driven disk (66); and the driven disk (66) is in an idling sleeve connection relationship with the periphery of the hammer disk (33) and is connected to the hammer handles (44). The hammer handles (44) are connected into an integral body by the driven disk (66), and when one of the hammer handles (44) swings, the swinging hammer handle drives other hammer handles to swing at the same amplitude and thus in hammer head working, energy is not lost easily, hammer head motion rigidity is improved without increasing of hammer head quality and a hammer head speed, and fragmentation effects are improved.

Description

A kind of rotor block of reversible disintegrating machine

Technical field

The present invention relates to the reversible disintegrating machine in the mining machinery field, be specifically related to the rotor block of reversible disintegrating machine.

Background technology

the rotor block of existing reversible disintegrating machine comprises main shaft 1, hammer dish 2, hammer handle 3, tup 4 and each connecting pin, wherein, one boss 8 is arranged in the middle of hammer handle 3, the one end connects tup 4 by hammer pin 5, the other end connects hammer dish 2 by hammer handle pin 6, and can under boss 8 restrictions, around hammer handle pin 6, do the swing of certain amplitude, its operation principle is: under motor drives, the rotor block High Rotation Speed, hammer handle becomes radial arrangement with tup under the effect of centrifugal force, material 7 is carried out to high speed to be hit broken, when a tup hits material, because energy loss causes Speed Reduction, this tup and hammer handle will swing backward around the hammer handle pin, then after non-strike zone absorbs the energy resume speed, prepare next time broken.

Mainly there is following shortcoming in the rotor block of this structure:

(1) during due to work, only have the part tup to swing, therefore very easily cause rotor block centre-of gravity shift, thereby cause vibration equipment.

(2) because crushing effect is directly related with the tup energy, and single tup finite energy.According to kinetic energy formula, improve the tup energy two kinds of methods are arranged: a kind of method is to increase the tup quality, and another kind of method is to increase ram velocity, but increase the tup quality, will increase the rotor block gross mass, make the electric motor starting difficulty and increase unloaded load, causing energy consumption to increase; Increase ram velocity and can cause vibration equipment to increase and tup wearing and tearing aggravation, shorten the service life of tup.

Summary of the invention

For above-mentioned deficiency, the invention provides a kind of rotor block, this rotor block, under the prerequisite that does not increase tup quality and speed, not only can improve the motion rigidity of tup, also can increase the blow energy of tup, greatly improves crushing effect.

The present invention realizes by such technical scheme: a kind of rotor block of reversible disintegrating machine, comprise main shaft, the hammer dish with pin-and-hole, hammer handle, tup and each connecting pin, these connecting pins comprise hammer pin and hammer handle pin, this rotor block also comprises a series of follower disks, this follower disk empty set is connected with hammer handle on the excircle of hammer dish and by follower peg, all like this hammer handles have connected into an integral body by follower disk, when a hammer handle swings, will drive all same swing amplitudes of all hammer handles.

Flexible installation for the ease of follower disk, hammer handle and hammer dish, on described follower disk, be provided with the decile pin-and-hole that equates with quantity on the hammer dish, these pin-and-holes are corresponding with the pin-and-hole position on the hammer dish, when all hammer handles are installed, can both become radial arrangement along the hammer disc radial.

Be further, the internal diameter of described follower disk is slightly larger than the external diameter of hammer dish, can make like this follower disk empty set flexible rotating on the excircle of hammer dish, and reduces the equipment vibration in when work.

Be further, the long handle section of described hammer handle arranges the hole of having strong market potential, one end of hammer handle is connected with tup by hammer pin, the other end is connected with the hammer dish by the hammer handle pin, middle part is connected with follower disk by follower peg, after the connection of all tups by hammer dish and follower disk, realize interlock, improved the motion rigidity of tup.

Owing to having adopted said structure, beneficial effect of the present invention is as follows:

(1) a series of follower disks of empty set on hammer dish excircle, all like this hammer handles have connected into an integral body by follower disk with the hammer dish, when a hammer handle swings, all same swing amplitudes of all hammer handles will be driven, therefore, under the prerequisite that does not increase tup quality and speed, can increase the motion rigidity of tup, improve crushing effect.

(2) due to all tup interlocks, the motion rigidity of single tup increases, in the situation that crushing effect is identical, the tup quality of reversible disintegrating machine can be less, reaches energy-conservation effect.

(3) due to all tup interlocks, the motion rigidity of single tup increases, in the situation that crushing effect is identical, the ram velocity of reversible disintegrating machine can be lower, reaches the effect that reduces to wear and tear, improve the life-span.

(4) because all tups all wait the amplitude interlock, or else rotor block there will be centre-of gravity shift, thereby can significantly reduce vibration equipment.

(5) because all tups all wait amplitude interlock, allow tup to produce more large angle pendulum, equipment is larger for tolerance that can not broken material, moves safer.

The specific embodiment

In order more to be expressly understood purpose of the present invention, technical scheme and beneficial effect, the present invention is described further below in conjunction with accompanying drawing, but protection scope of the present invention is not limited in following examples.

as shown in Figures 1 to 9, a kind of rotor block of reversible disintegrating machine, comprise main shaft 11, a series of dishes of hammer with pin-and-hole 22 33, hammer handle 44, tup 55 and each connecting pin, these connecting pins comprise the hammer pin 88 that connects hammer handle 44 and tup, the hammer handle pin 99 that connects hammer dish 33 and hammer handle 44, be these dishes of hammer with pin-and-hole 22 33, hammer handle 44, tup 55 and above-mentioned each connecting pin form a unit of rotor block, this rotor block also comprises the follower disk 66 of a series of unit, follower disk 66 empty sets of each unit are on the excircle of the hammer dish 33 of relevant position, by hammer dish 33 in these unit, hammer handle 44, tup 55 and each connecting pin, the parts that follower disk 66 grades connect into link together by main shaft 11 again, on described follower disk 66, be provided with the decile pin-and-hole 77 that equates with quantity on hammer dish 33, the internal diameter of described follower disk 66 is slightly larger than the external diameter of hammer dish 33, the long handle section of described hammer handle 44 arranges the hole of having strong market potential, and an end of hammer handle 44 is connected with tup 55 by hammer pin 88, and the other end is connected with hammer dish 33 by hammer handle pin 99, and middle part is passed through follower peg 100 and is connected with follower disk 66.

its operation principle is, under the driving of motor, the rotor block High Rotation Speed, hammer handle 44 becomes radial arrangement with tup 55 under the effect of centrifugal force, material is carried out to high speed to be hit broken, when one of them tup 55 hits material 200, due to energy loss, cause Speed Reduction, this tup 55 and hammer handle 44 will rotate backward around hammer handle pin 99, and drive also same swing amplitude of other hammer handle by follower peg 100 and follower disk 66, but due to other tup off-energy not, under centrifugal action, be held in radial, opposing is allowed to the power of its hammer handle with swing amplitude, support conversely this hammer handle also not swing backward, thereby increased the motion rigidity of this tup, improve crushing effect.
