As shown in fig. 3 and 4, the frame 1 of the present application further includes a first housing 11 and a second housing 12, wherein the first housing 11 covers the eccentric outer sleeve 3 to ensure effective arrangement of the eccentric outer sleeve 3 and the eccentric inner sleeve 2, and the second housing 12 covers the hydraulic clutch device 5 to ensure normal operation of the hydraulic clutch device 5. It has also been found that the second housing 12 is also able to limit the movement distance of the internal adjusting gear 4 from being lifted off the external second adjusting gear 31 too much.
Further, since both the first adjusting external gear 21 and the second adjusting external gear 31 are circularly provided, it is also possible to realize stepless adjustment of the eccentric inner sleeve 2 and the eccentric outer sleeve 3. Specifically, the eccentric inner sleeve 2 and the eccentric outer sleeve 3 can be always in a state to be abutted along with the mutual rotation of the eccentric inner sleeve 2 and the eccentric outer sleeve 3, at this time, the adjusting stage number between the eccentric inner sleeve 2 and the eccentric outer sleeve 3 is already dependent on the tooth shapes of the first adjusting external gear 21 and the second adjusting external gear 31, and when the tooth shapes of the two are sufficiently small, the stepless adjustment can be considered to be formed between the eccentric outer sleeve 3 and the eccentric inner sleeve 2.
Specifically, as shown in fig. 11 and 12, in some embodiments of the present application, the hydraulic clutch device 5 includes a hydraulic cylinder 51 and a jack-up disc 52 disposed on an output shaft of the hydraulic cylinder 51, corresponding to the hydraulic cylinder 51, an adjusting groove 41 is formed on an outer side surface of the adjusting internal gear 4, and the jack-up disc 52 is sleeved in the adjusting groove 41 and can rotate relative to the adjusting internal gear 4, so that the jack-up disc 52 is movably connected with the adjusting internal gear 4, and an influence of the jack-up disc 52 on a normal use of the adjusting internal gear 4 can be avoided. Specifically, when the adjusting internal gear 4 is meshed with the first adjusting external gear 21 and the second adjusting external gear 31, the position of the adjusting internal gear 4 is fixed, the jack plate 52 at this time can only rotate relative to the adjusting internal gear 4 without any influence on the limiting effect of the adjusting internal gear 4 when not acted on by the hydraulic ram 51, and when the jack plate 52 is acted on by the hydraulic ram 51, since it is provided in the adjusting groove 41 of the adjusting internal gear 4, it can drive the adjusting internal gear 4 to rise synchronously to realize the separation of the adjusting internal gear 4 from the first adjusting external gear 21 and the second adjusting external gear 31, and of course, it can also drive the adjusting internal gear 4 to descend again and return to the initial position under the reverse movement of the hydraulic ram 51 to mesh with the first adjusting external gear 21 and the second adjusting external gear 31 again to fix the eccentric inner sleeve 2 and the eccentric outer sleeve 3. Further, the hydraulic cylinder 51 is used for lifting the jacking plate 52 to drive the adjusting internal gear 4 to move along the axis thereof. Obviously, the sizes of the jacking disc 52 and the adjusting internal gear 4 can be adjusted along with the sizes of the eccentric inner sleeve 2 and the eccentric outer sleeve 3, and in order to ensure the jacking effect of the adjusting internal gear 4, a plurality of hydraulic cylinders 51 can be arranged at the moment, two hydraulic cylinders 51 are arranged in the embodiment of the invention, and the two hydraulic cylinders 51 are respectively positioned at two sides of the main shaft 8 and symmetrically arranged along the plane of the main shaft 8.
Still further, the frame 1 of this application includes third casing 13, and hydraulic cylinder 51 locates on the third casing 13 and is connected with third casing 13, and third casing 13 can provide the landing point for the setting of hydraulic cylinder 51, can carry out the spacing simultaneously and avoid its continuous decline and drop from first regulation external gear 21 of descending of regulation internal gear 4.
Optionally, as shown in fig. 8, 9, 15 and 16, in some embodiments of the present application, the top of the inner circular surface of the eccentric outer sleeve 3 is recessed inwards to form an assembling groove 32, and correspondingly, the top of the outer circular surface of the eccentric inner sleeve 2 extends outwards to form an assembling protrusion 22, when the eccentric inner sleeve 2 is arranged in the eccentric outer sleeve 3, the assembling protrusion 22 is clamped into the assembling groove 32, so that quick positioning of the eccentric inner sleeve 2 and the eccentric outer sleeve 3 is realized, and meanwhile, the assembling groove 32 and the assembling protrusion 22 can also ensure that the eccentric inner sleeve 2 always falls on the eccentric outer sleeve 3, so as to strengthen the connecting effect between the two.
Alternatively, as shown in fig. 6, in some embodiments of the present application, the driving gear pair 6 of the cone crusher stroke adjustment device includes a driving pinion 61 and a driving gearwheel 62, wherein the driving gearwheel 62 is sleeved on the outer circumferential surface of the eccentric outer sleeve 3 and is just connected with the eccentric outer sleeve 3, and the driving pinion 61 is meshed with the driving gearwheel 62. When in use, the motor is started to drive the pinion 61 to rotate, and the driving large gear 62 meshed with the driving pinion 61 rotates and drives the eccentric sleeve 3 which is just connected with the driving large gear to rotate. At this time, if the adjusting internal gear 4 is meshed with the first adjusting external gear 21 and the second adjusting external gear 31, the eccentric outer sleeve 3 is fixedly connected with the eccentric inner sleeve 2, and the eccentric outer sleeve 3 drives the eccentric inner sleeve 2 to rotate together; at this time, how the adjusting internal gear 4 is not meshed with the first adjusting external gear 21 or the second adjusting external gear 31, the eccentric outer sleeve 3 is not fixedly connected with the eccentric inner sleeve 2, and at this time, the eccentric outer sleeve 3 rotates relative to the eccentric inner sleeve 2 to adjust the eccentric amount therebetween.
Alternatively, as shown in fig. 13 and 14, in some embodiments of the present application, the inner hole portion of the eccentric inner sleeve 2 is recessed to form an auxiliary groove 23, and a joint sleeve 7 is provided in the auxiliary groove 23, and the joint sleeve 7 is sleeved on the main shaft 8 and is used for assisting the movement of the main shaft 8. It can be found that the main shaft 8 of the cone crusher is suspended at a fixed suspension point on the beam, and the other end is inserted into the eccentric inner sleeve 2 and can make continuous eccentric rotary motion around the axis where the center of the outer circular surface of the eccentric inner sleeve 2 is located under the drive of the driving gear pair 6. Therefore, in order to reduce the abrasion between the main shaft 8 and the eccentric inner sleeve 2, the service lives of the main shaft 8 and the eccentric inner sleeve 2 are prolonged, the eccentric inner sleeve 2 of the device is sunken to form an auxiliary groove 23 in the middle of an inner hole, the groove wall of the auxiliary groove 23 is arranged in an arc surface, the joint sleeve 7 sleeved on the main shaft 8 is arranged in the auxiliary groove 23, the joint sleeve 7 is made of rubber materials, the main shaft 8 can be prevented from being directly collided with the eccentric inner sleeve 2, and stress buffering between the main shaft 8 and the eccentric inner sleeve 2 is realized. Further, the joint sleeve 7 includes a flat portion 71 and spherical portions 72 provided at both ends of the flat portion 71, the flat portion 71 abutting against the groove wall of the auxiliary groove 23 to restrict the main shaft 8 to ensure its stability in the eccentric inner sleeve 2, the spherical portions 72 being for filling the gap between the main shaft 8 and the eccentric inner sleeve 2 and replacing the main shaft 8 against the eccentric inner sleeve 2 when the main shaft 8 makes an eccentric rotational movement.
Further, as shown in fig. 15, for the eccentric inner sleeve 2 of the present application, the thickness of the eccentric inner sleeve is gradually reduced from the middle portion to the two ends, that is, the schematic cross-sectional structure of the eccentric inner sleeve 2 is trapezoidal, in fact, the present application still needs to consider the influence of the eccentric rotary motion of the spindle 8 on the inner hole of the eccentric inner sleeve 2 after the joint sleeve 7 is arranged, and the arrangement of the joint sleeve 7 can reduce the contact and wear between the middle portion of the spindle 8 and the eccentric inner sleeve 2, but cannot ensure that other portions of the spindle 8 are not contacted with the eccentric inner sleeve 2 during the eccentric rotary motion, and if the inner hole size of the eccentric inner sleeve 2 is too small, the situation that the spindle 8 is blocked by the eccentric inner sleeve 2 can also occur. Therefore, considering the amplitude of the rotary motion of the main shaft 8, the inner hole of the eccentric inner sleeve 2 is cut, so that the main shaft 8 only abuts against the eccentric inner sleeve 2 through the joint sleeve 7 when moving in the eccentric inner sleeve 2, and other parts of the main shaft 8 are prevented from striking the eccentric inner sleeve 2.
It is obvious that for the hydraulic clutch device 5 and the driving gear pair 6 of the present application, the operator can also electrically connect them with the controller so as to realize the automatic operation of the driving devices by means of the controller, thereby realizing the automatic adjustment of the cone crusher stroke.
In addition, for the eccentricity e of the eccentric rotational movement of the spindle 8 of the present application, the following formula can be used:
e＝sin(a/2)＊e＇＊2；
wherein e is the adjusted eccentricity, and the length of a connecting line between the center of the inner circular surface of the eccentric inner sleeve 2 and the center of the outer circular surface of the eccentric outer sleeve 3 is also as follows:
a is an included angle between the connecting line of the circle centers of the inner and outer circular surfaces of the eccentric outer sleeve 3 and the connecting line of the circle centers of the inner and outer circular surfaces of the eccentric inner sleeve 2;
e' is the connecting line length of the center of the inner and outer circular surfaces of the eccentric sleeve 3.
