Description

Изобретение относитс к дробильно- размольному оборудованию, а именно к конусным гирационным дробилкам дл мелкого дроблени руд и других материалов в различных отрасл х промышленности .The invention relates to crushing and grinding equipment, namely, cone gyratory crushers for fine crushing of ores and other materials in various industries.

Цель изобретени - повышение производительности и надежности дробилки .The purpose of the invention is to increase the productivity and reliability of the crusher.

На фиг.1 схематически изображена предлагаема дробилка, общий вид; на фиг.2 - верхн часть корпуса дробилки.In Fig.1 schematically shows the proposed crusher, a general view; figure 2 - upper part of the body of the crusher.

Конусна гирационна дробилка содержит корпус 1, неподвижный конус 2 с пружинами 3, сферическую опору 4, на которой установлен подвижный дроб щий конус 5 с валом 6, нижний конец которого через шарнир 7 сопр жен с подвижным поводком 8, расположенным в радиальном пазу вала 9 горизонтальной конической шестерни 10, котора снабжена противовесом 11, Поводок 8 смещен относительно оси дробилки предварительно сжатым упругим элементом 12, упирающимс одним концом в вал 9, а другим - в поводок 8 таким образом, что образующа The cone gyratory crusher comprises a housing 1, a fixed cone 2 with springs 3, a spherical support 4 on which a movable crushing cone 5 is installed with a shaft 6, the lower end of which through a hinge 7 is mated with a movable lead 8 located in the horizontal groove of the shaft 9 bevel gear 10, which is equipped with a counterweight 11, the Leader 8 is displaced relative to the crusher's axis by the pre-compressed elastic element 12, abutting one end against the shaft 9, and the other on the leash 8 so that it forms

Пружины 3 совместно с упругим элементом 12 предохран ют дробилку от перегрузок при попа дании в нее недробимого предмета. Поскольку верхний конец вала 6 подвижного дроб щего конуса 5 расположен выше центра сферической опоры 4, он прецессирует относительно оси дробилки, и через сферический шарнир 15 и подвижньш поводок 16 приводит во вращательное движение дебаланс 17These 19 and then between the armors of the stationary cone 2 and the movable cone 5. The springs 3, together with the elastic element 12, prevent the crusher from overloading if an inaccessible object falls into it. Since the upper end of the shaft 6 of the movable crushing cone 5 is located above the center of the spherical support 4, it precesses relative to the crusher's axis, and through the spherical hinge 15 and the movable leash 16 rotates debalance 17

This allows the crusher to be balanced as much as possible on the foundation.

Claims

increase reliability and increase crusher productivity by 15-20%. Claims. 1. A cone gyratory crusher comprising a body, a fixed outward stationary cone 2, is closed. The horizontal bevel gear 10 through the vertical bevel gear 13 mates with the drive shaft 14. The upper end of the shaft 6 of the movable crushing cone 5 through the hinge 15 is coupled to the driver 16, mounted so as to move in the radial slot of the unbalance 17, made, for example, the form of a distribution funnel mounted in bearings 18 in the upper part of the housing 1, which has a loading opening 19.

The cone gyratory crusher operates as follows.

The torque from the drive shaft 14 is transmitted through a bevel gear drive to the shaft 9, which through the lead 8 transfers it to the movable crushing cone 5. Due to the displacement of the lead 8 by means of an elastic element 12 relative to the crusher axis, the crushing cone 5 is eccentrically arranged and makes a gyratory movement, rolling on the fixed cone 2. As a result of this movement, the material supplied to the crusher is crushed through the opening

These 19 and then between the armor of the stationary cone 2 and the movable cone 5. The springs 3, together with the elastic element 12, prevent the crusher from overloading if an inaccessible object falls into it. Since the upper end of the shaft 6 of the movable crushing cone 5 is located above the center of the spherical support 4, it precesses relative to the crusher's axis, and through the spherical hinge 15 and the movable lead 16, the unbalance 17 rotates.

The masses and the location of the centers of mass of the unbalance 17 and the counterweight 11 mounted on a horizontal bevel gear are chosen so that the resultant inertial forces arising during their rotation will be equal in magnitude to the inertial force of the movable crushing cone 5 opposite to it in direction and lie with it in one horizontal plane. This allows the crusher to be balanced as much as possible on the foundation.

The invention makes it possible to reduce the dynamic loads on the shot ™ foundation to exclude hull oscillations.

increase reliability and increase crusher productivity by 15-20%. Claims. 1. A cone gyratory crusher comprising a housing, a stationary outer cone with springs, a movable inner cone mounted on a lower spherical support, an actuator having a gear conical transmission in which the shaft is horizontal

the bevel gear is made with a driver pivotally connected to the shaft end of the movable cone and displaced relative to the crusher axis by means of an elastic element, characterized in that

the goal of increasing crusher performance and reliability, it is equipped with an imbalance installed in the upper part of the body with a movable leash,

while the latter is pivotally connected to the upper end of the shaft of the movable cone, and the center of gravity of the unbalance is offset relative to the crusher axis in the direction opposite to the displacement of the movable cone.

2. Crusher according to Claim 1, characterized in that the unbalance is made in the form of a charging funnel with an eccentric cavity.
