Description

A kind of rotor block of Reversible crusher

Technical field

The present invention relates to the Reversible crusher in mining machinery field, be specifically related to the rotor block of Reversible crusher.

Background technology

The rotor block of existing Reversible crusher comprises main shaft 1, hammer dish 2, hammer handle 3, tup 4 and each connecting pin, wherein, a boss 8 is had in the middle of hammer handle 3, its one end connects tup 4 by hammer pin 5, the other end connects hammer dish 2 by hammer handle pin 6, and under boss 8 limits, the swing of certain amplitude can be done around hammer handle pin 6, its operation principle is: under motor drives, rotor block High Rotation Speed, hammer handle becomes radial arrangement under the influence of centrifugal force with tup, high speed is carried out to material 7 and hits fragmentation, when a tup hits material, because energy loss causes speed to reduce, this tup and hammer handle will swing backward around hammer handle pin, then once broken on preparing after non-strike region absorption energy resume speed.

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

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

(2) because crushing effect is directly related with tup energy, and single tup finite energy.According to kinetic energy formula, improve tup energy and have two kinds of methods: a kind of method increases tup quality, another kind of method increases ram velocity, but increase tup quality will increase rotor block gross mass, make electric motor starting difficulty and increase unloaded load, causing energy consumption to increase; Increasing ram velocity can cause vibration equipment to increase and tup wearing and tearing aggravation, shortens 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 not increasing tup quality and speed, not only can improve the motion rigidity of tup, also can increase the blow energy of tup, greatly improve crushing effect.

The present invention is realized by such technical scheme: a kind of rotor block of Reversible crusher, comprise main shaft, the hammer dish being 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 disk, this follower disk empty set is on the excircle of hammer dish and be connected with hammer handle by follower peg, hammer handles all has like this connected into an entirety by follower disk, when a hammer handle swings, will drive all same swing amplitudes of hammer handle.

For the ease of the flexible installation of follower disk, hammer handle and hammer dish, described follower disk is provided with the decile pin-and-hole equal with quantity on hammer dish, these pin-and-holes are corresponding with the pin-and-hole position on hammer dish, when all hammer handles are installed, can both become radial arrangement along hammer dish radial direction.

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

Be further, the long handle portion of described hammer handle arranges a long pinhole, one end of hammer handle is connected with tup by hammer pin, the other end is connected with hammer dish by hammer handle pin, middle part is connected with follower disk by follower peg, all tups, by after the connection of hammer dish and follower disk, realize interlock, improve the motion rigidity of tup.

Owing to have employed said structure, beneficial effect of the present invention is as follows:

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

(2) because all tups link, the motion rigidity of single tup increases, and when crushing effect is identical, the tup quality of Reversible crusher can be less, reaches energy-conservation effect.

(3) because all tups link, the motion rigidity of single tup increases, and when crushing effect is identical, the ram velocity of Reversible crusher can be lower, reaches the effect reducing wearing and tearing, improve the life-span.

(4) due to the amplitude interlock such as all of all tups, or else rotor block there will be centre-of gravity shift, thus significantly can reduce vibration equipment.

(5) due to the amplitude interlock such as all of all tups, allow tup to produce greater angle and swing, equipment for can not the tolerance of broken material larger, run safer.

Detailed description of the invention

In order to clearly understand object of the present invention, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the present invention is described further, but protection scope of the present invention do not limited in the examples below.

As shown in Figures 1 to 9, a kind of rotor block of Reversible crusher, comprise main shaft 11, the hammer dish 33 of a series of band pin-and-hole 22, hammer handle 44, tup 55 and each connecting pin, these connecting pins comprise the hammer pin 88 connecting hammer handle 44 and tup, connect the hammer handle pin 99 of hammer dish 33 and hammer handle 44, the i.e. hammer dish 33 of these band pin-and-holes 22, hammer handle 44, a unit of tup 55 and above-mentioned each connecting pin composition rotor block, this rotor block also comprises the follower disk 66 of a series of unit, follower disk 66 empty set of each unit is 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 etc. connects into are linked together by main shaft 11 again, described follower disk 66 is provided with the decile pin-and-hole 77 equal 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 portion of described hammer handle 44 arranges a long pinhole, and one 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 connected with follower disk 66 by follower peg 100.

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