(54) КОНУСНАЯ ДРОБИЛКА(54) CONE CRUSHER

Изобретение относитс к дробильным машинам, в частности к дробилкам среднего и мелкого дроблени .The invention relates to crushing machines, in particular to medium and fine crushing crushers.

Известны конусные дробилки среднего и мелкого дроблени , предназначенные дл переработки горных пород, с6держаюие подвижный конус, неподвижный конус, станину и эксцентриковый узел, выполненный в виде стакана l .Known cone crushers medium and fine crushing, intended for the processing of rocks, with a movable cone, fixed cone, frame and eccentric node, made in the form of a glass l.

Указанные конусные дробилки относ тс к схемам, где дроб щим конусом вл етс внутренний, а оси дробилок пересекаютс в точке, расположенной выше камеры дроблени .These cone crushers belong to schemes where the crushing cone is internal, and the axes of the crushers intersect at a point above the crushing chamber.

Конусные дробилки данного вида нашли наиболее широкое применение в практике.Cone crushers of this type are most widely used in practice.

По своей техничедкой сущности наиболее близкой к изобретению : вл етс конусна дробилка, содержаща станину с наружным неподвижным ког . нусом, внутренний дроб щий конус со сферической опорной частью и хвостовиком вгша, размещенным в стакане эксцентрикового опорного узла, выполненном со смещенным отверстием, ось которйэго развернута и наклонена относительно оси стакана 2j .According to its technical essence, it is closest to the invention: it is a cone crusher containing a frame with an external fixed frame. In this case, an internal crushing cone with a spherical bearing part and a shank placed in an eccentric glass assembly made with an offset hole, the axis of which is turned and inclined relative to the axis of the glass 2j.

Хот в указанной дробилке конструкци эксцентрикового опорного узла и позвол ет повысить производительность дробилки путем изменени кинематики движени подвижного конуса , однако не позвол ет упростить в целом конструктивную схему дробилки и снизить трудоемкость при техни - ческом обслуживании дробилки. Наличие сферического подшипника, размещенного в станине, и отдельного эксцентрикового узла делают конструкцию дробилки сложили, а техническое обе-, служйвание трудоемким.Although, in this crusher, the design of the eccentric support unit improves the crusher's performance by changing the kinematics of the moving cone movement, but it does not simplify the overall design of the crusher and reduce the labor intensity during the technical maintenance of the crusher. The presence of a spherical bearing placed in the frame and a separate eccentric assembly make the crusher structure folded, and the technical maintenance is laborious.

изобретени вл етс упрощение конструкций и снижение эксплуатационных затрат. the invention is to simplify structures and reduce operating costs.

jn bed with an external fixed coyus, internal crushing cone with a spherical bearing part and a tail-. Wick a shaft of a rozmizdnell in a glass of an eccentric support unit, made with an offset hole, the axis of which is turned and tilted relative to the axis of the glass, the upper iacTb of the glass is made, the spherical and center of the sphere on the axis of symmetry of the hole of the glass wall and connected with the sphere supporting internal part fractional cone free landing. FIG. 1 shows a general view of a cone crusher; in fig. 2 - the location of the axes and eccentricity between them (top view); The crusher's construction contains a leading gear L connected to a dvng (body, driven gear 2, a gesture attached to the eccentric cup 3, a movable cone 4 with a shaft and a fixed cone 5. The eccentric cup 3 on its outer surface is made in a symmetrical axis 00, presently the crusher axis, the hole in the glass and the spherical base for the movable cone to be made are made symmetrical about the 0 0 axis, is the ring and the axis of the dedvizhny cone. The radius of the XF sphere I lies on the axis OiOvt. with symmetry, the whole crusher 00 intersects with the axis of the movable cone at an angle) f. In the section of the crusher (FIG. 1), the axis of crossing of the axes passes at the level of the lower base of the movable cone. FIG. The 2 axis of the crusher 00 is designed to a point, and the axis of the mobile cone 0 О passes from this point on the distance (eccentricity) The rotation angle of the segment of the shortest distance between the axes (eccentricity) e is indicated by Cf and is shown in the diagram. These parameters Jj, e (f determine the kinematics of the moving coil. Crusher operation. When the gear 1 rotates, the rotational motion is transmitted to the gear 2, which is rigidly fixed to the eccentric cup 3. The eccentric cup 3 rotates about the axis 00. The axis of the moving cone 0 0 / | rotation eccentric Rica 3 describes a hyperbolic surface relative to axis 00. With the start of movement, the eccentric 3 begins its rotational movement and the moving cone 4, the cantilever shaft of which is placed in the hole of the eccentric glass. If there are no pieces of rock in the crushing chamber, the eccentric glass 3 and the moving cone 4 may drag with respect to the axis 00 as a unit e is whole. When f penetrates into the material crushing chamber, an inhibitory moment is created, which jointly in the escapement of the eccentric cup and the movable cone, the moving crush, continuing with The rotational motion relative to the axis 00 begins to rotate at the same time around axis 0. Moreover, the directions of rotation have an opposite sign. The movable cone slides along the spherical surface of the eccentric glass and along the surface of the displaced conical opening of the glass. The moving cone, which is entrained in the motion by an eccentric cup, approaching the fixed cone, distorts the rock pieces and destroys them. As the moving cone moves away from the stationary, the crushed material falls out of the chamber. The rest of the cycle repeats. The forces arising from the crushing of the material are transmitted through the cone to the spherical surface of the ex-, centric cup, and through it to the frame. The technical and economic efficiency of the proposed technical solution is to simplify the design of the crusher. The bed of the proposed crusher does not have a spherical base for accommodating a rolling cone 7, which simplifies the manufacture and processing of the bed. The complication of the design of an eccentric cup, as a result of the appearance of an additional spherical surface, is economically much cheaper than making a sphere on a bed. Simplified and maintenance of the crusher, as the summing up, lubrication is required only to the surfaces of the eccentric glass in contact with the surfaces of the bed and the moving cone. In addition, access to the crusher gap is improved, which allows the crusher to be accelerated to the appropriate slot. The invention of the Cone Crusher, containing a frame with an external fixed KOHJJ COM, internal crushing cone with a spherical bearing and a shaft shank placed in a glass of an eccentric support unit, made with an offset hole, the axis of which is turned and inclined relative to the axis of the glass, that in order to simplify the design and reduce operating costs, the upper part of the glass is made spherical with the center of the sphere on the axis of symmetry of the glass hole and is associated with the spherical support astyu inner cone of crushed present loose fit ,.
