Abstract

PROBLEM TO BE SOLVED: To prevent the non-uniform abrasion of a gear or the like caused by vibration during operation and to easily and accurately adjust the cross-sectional area of a crushing chamber by combining a follower mechanism with a drive gear so as to be capable of following the up and down movement of an adjusting frame supporting a concave accompanied by the rotation of the follower gear attached to the adjusting frame. SOLUTION: A drive gear 32 is rotationally driven by a motor 31 fitted with a cyclo-speed reducer 30 in order to adjust the cross-sectional area of a crushing chamber 21 being the gap between a concave 20 and a mantle 18 to rotationally drive the follower gear 29 meshed with the drive gear 32. An adjusting frame 25 is moved up and down with respect to an upper body 19 to move the concave 20 supported on the adjusting frame 25 by a support mechanism 27. Since the screw pitch of the screw rod 34 integrally arranged to the rotary shaft of the drive gear 32 is synchronous to the up and down pitch of the adjusting frame 25, the up and down movement of the drive gear 32 can be allowed to coincide with that of the follower gear 29.

According to the present invention, there is provided a set adjusting device for a rotary crusher, which moves up and down by rotating a cone cable side of the rotary crusher. The driving gear is combined with a follow-up mechanism so as to be able to follow up and down movement accompanying rotation of the driven gear attached to the adjusting frame which fixedly supports the cone cave.

[0006] One of the follow-up mechanisms in the set adjusting device of the above-mentioned rotary crusher is an adjusting frame in which a screw rod is provided integrally with a rotating shaft of a driving gear, and a screw pitch of the screw rod and a cone cable are fixedly supported. And a mechanism for synchronizing the vertical pitch of the driven gear and the vertical movement of the driven gear and the driving gear assembled to the adjustment frame.

Another one of the following mechanisms in the set adjusting device of the driven crusher is that the upper and lower surfaces of a driven gear mounted on an adjustment frame fixedly supporting a cone cable are sandwiched therebetween, and the driven gear is rotated by the vertical movement of the driven gear. A ring that follows only in the vertical direction is attached to the top and bottom of the driving gear via bearings, and the driven gear moves up and down, so that the driving gear passes along the guide rod provided integrally with its rotating shaft via the ring. The mechanism is characterized in that the mechanism moves up and down to follow.

[0012]

As can be seen from the above description, the set adjusting device of the rotary crusher according to the present invention combines a drive gear with a follow-up mechanism capable of following up and down movements of a driven gear. The driven gear can be fixedly supported on the adjustment frame, and uneven wear of the gear and the slide portion due to vibration during operation can be prevented. In addition, since the driven gear is rotated by the driving gear combined with the following mechanism, and the cone cable side is moved up and down, it is not necessary to use a vertically long driving gear as the conventional driving gear. The wear difference in the case of using a gear can be eliminated. Therefore, according to the set adjusting device of the rotary crusher of the present invention, it is possible to smoothly and accurately adjust the cross section of the crushing chamber, which is the gap between the cone cave and the mantle.
