Description

2. A conical gyratory crusher containing a bed with a stationary cone and an internal hollow crushing cone, the shaft of which is kinematically connected to a drive, characterized in that, in order to intensify the grinding process and increase the uniformity of the granule of the metric composition of the finished product, the drive is made in the form of an equal-arm carrier fixed on the shaft with the possibility of free rotation, coupled with the shaft by means of a planetary gear transmission, with axes with rotation bodies mounted on each shoulder of the carrier, ontaktiruyuschimi with the inner surface conductive crushed cone.

The invention relates to cone crushers used for crushing ores and nonmetallic materials in the building materials industry, the mining industry and chemical technology.

Cone crushers are known, which contain a bed, a fixed and crushing cones drive. The fixed shaft is rigidly connected with the crusher bed, and the movable one is mounted on the axle. In one design, the lower end of the axis is eccentric in the drive part, and as the part is rotated, the axis describes a cone with a vertex at the point of attachment of the other end of the axis. In other constructions, the fastening of the axis is accomplished by B1 of coaxial bearing with eccentric TOM relative to the axis of the fixed cone C.

With this rotation, the fraction 1cc cone in one part of the circumference approaches the immobile cone of the crusher, destroying the material, and in the other diametrically opposite part of the circle, moves away from the stationary cone, and the crushed material is poured out through the expanded exit slit.

The disadvantage of such crushers is that, along with crushing and splitting of the material, its abrasion takes place, because the crushing cone during rotation not only rolls, but also slides relative to the fixed crusher cone, which increases the unevenness of the particle size distribution of the crushed material and increases the load on the drive.

The closest to the proposed technical essence is

A gyratory cone crusher containing a frame with a stationary cone and an internal hollow crushing cone, the shaft of which is kinematically connected to the drive. This connection is made in the form of rods interacting with the crushing cone C23.

The known cone crusher does not solve the task of organizing the movement of the crushing cone and does not eliminate the effects of abrasion during crushing, since the coupling of the drive shaft with the crushing cone remains invariably rigid in stationary mode of operation,

The purpose of the invention is to intensify the grinding process and improve the uniformity of the particle size distribution of the finished product.

This goal is achieved by the fact that in a cone gyratory crusher containing a bed with a stationary cone and an internal hollow crushing: a cone, the shaft of which is kinematically connected to the drive, the drive is performed as a Each of its shoulders has axes with bodies of rotation in contact with the inner surface of the grinding cone to form corresponding rolling pairs.

According to the second variant, the drive is made in the form of an equal shoulder 1 zodil attached to the shaft, which is coupled to the shaft by means of a planetary gear transmission, while axes with rotation bodies in contact with the inner surface of the grinding cone are mounted on the carrier's shoulder. FIG. 1 is a schematic diagram of a cone crusher, the axis of the drive shaft is parallel to the axis of the crushing cone; FIG. 2 - the same, the axis of the drive shaft is not parallel to the axis of the crushing cone; in FIG. 3 - 6 are versions of the bodies of rotation and the shape of the support surface of the grinding cone at the place where the rolling pair is formed,. in fig. 7 - cone crusher with unequal carrier; in fig. 8 is a section AA, in FIG. 7, in FIG. 9, FIG. 10 (section BB in FIG. 9), FIG. 11, FIG. 12 (section BB in FIG. 11), FIG. 13 and FIG. 14 (section GGD in Fig. 13) is a tapered shotgun with an equal shoulder carrier with different versions of the drive unit. The cone crusher (Figs. 1 and 2) contains a frame 1 on which a fixed cone 2 is attached, a movable crushing cone 3 is mounted on the drive shaft 4, and the drive shaft 4 carries the carrier 5 rigidly attached to it, having axes 6 on which it is movable Rotation bodies 7 are installed. The latter can be made barrel-shaped (Fig. 3), in the shape of a cone (Fig. 4) or a cylinder (Fig. 5), while the inner rolling surface of the crushing cone can accordingly be shaped as a cone. (Fig. 3 and 4), shchindra (Fig. 5) or grooves (Fig.6 Moreover, the cone crusher can have There are various variants of the drive units. So in Fig. 7, the drive is made in the form of an unbalanced carrier 5 fixed on the drive shaft 4. In Fig. 9 and 10 there is shown a drive device executed in the form of an equal shoulder 5 mounted on the drive shaft 4 and supporting axis 6 with rotation bodies 7 forming rolling pairs with an inner surface of a crushing cone 3, gears 8 are also mounted on axis 6 forming an engagement with a gear wheel 9 mounted on a fixed shaft 4 in the form of a planetary gear. In FIG. 11-14 so far: a drive device, made in the form of an equal shoulder carrier 5, movably mounted on the drive shaft 4, is mounted. On the carrier 5, the axle 6 is movably mounted, each of which has a movable rotation body 7 and fixed gears 8 and 10 which, respectively, engage with the wheels 9 and 11 mounted on the drive shaft 4, the wheel 9 being fixed relative to the shaft 4, and the wheel 11 being movable. The kinematic coupling of the gear wheels is made according to the two-stage planetary gear scheme. Cone crusher (Fig. 1, 2, 7) works as follows. The shaft 4 is set in motion from the motor, rotating, it rotates the carrier 5 rigidly attached to it. When the carrier 5 rotates, axis 6 moves in a circle whose center is shaft 4, while rotation bodies 7 move, making a relative rotation and axis 6. around the shaft 4 - a portable movement together with the axis 6. At the same time, the rotation bodies 7, rolling over the inner surface of the splitting cone 3, turn it, causing it to roll along the crushed material without sliding. Cone crusher, having equal shoulders drove (Fig. 9, 10) works as follows. The carrier 5 is set in motion from the engine, rotating relative to the shaft 4, while the shaft 4 and the wheel 9 fixed rigidly on it are stationary, and the wheels 8, which are movably located on the axis x 6, roll around the shaft 4 along the wheel 9, while the bodies of rotation 7 rotate the grinding cone 3, causing it to roll without sliding over the material being crushed. Cone crusher (Fig. 11-14) in the variant with a two-stage planetary gear works as follows. One of the central wheels 9 (or 11) is transmitted from the engine. The wheel 9 (or 11) rotates the wheels 8 (or 10) located on the wasps. x 6 drove 5, while the wheels, 10 (or 8), also located on axles x 6, roll on a fixed wheel 11 (or 9). Ori the movement of the axles 6 rotates the rotation bodies 7, turning the crushing cone 3, causing it to roll without sliding over the material being crushed. Thus, the crushing cone of the cone crusher is driven with the organization of cone elimination as pure rolling over the layer of the crushed material with the realization of crushing and splitting only, eliminating abrasion, this allows to obtain a more uniform particle size distribution of the crushed material, and this the turn allows at the next stage to accomplish the share of the use of raw materials and, consequently, reduce the cost of the final product.
