Abstract

The utility model discloses a rotor body of a reversible crushing machine. The rotor body comprises a main shaft (1), hammer disks (33) with pin holes (22), hammer handles (44), hammer heads (55) and various connecting pins, and is characterized by also comprising a series of follower plates (66); the follower plates (66) are sleeved on the outer circumferences of the hammer disks (33) and are connected with the hammer handles (44), so that all the hammer handles are connected into a whole through the follower plates; when one of the hammer handles is swung, all the hammer handles are driven to swing with the same amplitude, so that energy does not lose when the hammer heads work; the movement rigidity of the hammer heads can be improved and the crushing effect is improved on the premise of not increasing the weight and the speed of the hammer heads.

Description

A kind of rotor block of reversible disintegrating machine

Technical field

The utility model relates to the reversible disintegrating machine in mining machinery field, is 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, in the middle of hammer handle 3, there is a boss 8, its 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, 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 hammer handle pin, then once broken on preparing after non-strike region absorbs energy resume speed.

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

(1) during due to work, only have 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 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 is to increase tup quality, another kind of method is to increase 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; Increase ram velocity and can cause vibration equipment to increase and tup wearing and tearing aggravation, shorten the service life of tup.

Utility model content

For above-mentioned deficiency, the utility model provides a kind of rotor block, and this rotor block is not increasing under the prerequisite of 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 utility model is to realize 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, all same swing amplitudes of all hammer handles will be driven.

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 equating 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 disc radial.

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 portion 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 hammer dish by 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, the beneficial effects of the utility model are 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 hammer dish, when a hammer handle swings, all same swing amplitudes of all hammer handles will be driven, therefore, do not increasing under the prerequisite of tup quality and speed, can increase the motion rigidity of tup, improving crushing effect.

(2) due to all tup interlocks, the motion rigidity of single tup increases, and 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, and in the situation that crushing effect is identical, the ram velocity of reversible disintegrating machine can be lower, reaches the effect that reduces wearing and tearing, improves 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, thereby can significantly reduce vibration equipment.

(5) due to the amplitude interlock such as all of all tups, 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 to be more expressly understood the purpose of this utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the utility model is described further, but protection domain of the present utility model 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 hammer dishes 33 with pin-and-hole 22, 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 that these are with the hammer dish 33 of pin-and-hole 22, 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, 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 equating 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 the hole of having strong market potential, 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 passed through follower peg 100 and is connected with follower disk 66.

Its operation principle is, under the driving of motor, 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.
