Изобретение относитс к конусным дробилкам дл мелкого и среднего дроблени , имеющим нижнюю сферическую опору подвижного конуса, и может быть использовано во всех отрасл х промышленности, где требуетс мелкое и среднее дробление различных материалов, например в горнометаллургической , химической и строительной .The invention relates to cone crushers for fine and medium crushing, having a lower spherical support for a moving cone, and can be used in all industries that require fine and medium crushing of various materials, for example, in mining, chemical, and construction.

Конусные дробилки благодар своим высоким эксплуатационным качест- . вам получили наибольшее распространение в промышленности.Cone crushers thanks to their high operational quality. you are most prevalent in the industry.

Однако конусные дробилки динамически не уравновешеш:, что требует дл них сооружени массивных фундаментов и ограничивает их технологические возможности,However, cone crushers are not dynamically balanced:, which requires them to build massive foundations and limits their technological capabilities,

Известна эксцентрикова дробилка , включающа корпус с наружным конусом и сферической опорой, на которой установлен внутренний подвижной конус с распределительной плитой на своей вершине и валом, смонтированным в подшипнике приводной эксцентриковой втулки с дебалансным зубчатым колесом, п той и подп тником 1 .An eccentric crusher is known, comprising a housing with an outer cone and a spherical support on which an inner movable cone is mounted with a distribution plate at its top and a shaft mounted in a bearing of a drive eccentric sleeve with an unbalanced gear wheel, the fifth and the subframe 1.

В таких дробилках гирационное движение подвижного конуса создает центробежную силу, достигаю1т5ю 20 т,приложенную к центру т жести конусаIn such crushers, the gyration motion of the moving cone creates a centrifugal force, reaching 20 tons, applied to the center of the cone's gravity

Однако и в этом случае сила, дейThis balanced force acting on the crusher is partially balanced by the unbalance of the concentric bushing, the weight of its gear and the mass of the distributor plate, the scattered center of the spherical support of the movable cone. However, in this case, the force

Claims

20 a crusher comprising a housing with a fixed cone and a lower spherical support of a movable cone balanced at idle with a cone: a raw material dispenser on its top and a shaft of a movable cone mouth; anoElly in a drive eccentric bushing fitted with a balancer, connected by means of a pin to a support heel having a central bore under the hinge shaft of the movable cone and in contact with the bib 2, due to the out-of-phase installation of loads on the bushing and their special placement along its height balancing the crusher, but not its cone. Among the shortcomings of the design of this crusher, it is necessary to attribute the fact that the moment from the antiphase weights distorts the sleeve, creates burns and can take it out. Even if the moment acting on the foundation is reduced to zero, the horizontal force is still shifted . To completely balance it requires that the sum of the forces and moments be equal to zero. In addition, the moving cone at idle can still tip over on a spherical support, which prevents its number of swings from rising. The purpose of the invention is to improve the technological parameters of the crusher by increasing the number of taper oscillations. This goal is achieved by the fact that in a cone eccentric crusher, which includes a housing with a fixed cone and a lower spherical support, a movable cone balanced at idle speed with a source material distributor mounted on its top and a movable cone shaft installed in a fitted cone load drive eccentric ;. a tricot bushing connected by means of a pin with a support heel, immersing the central bore floor of the shank of the movable cone shaft and contacting with the liner; the supporting pin of the eccentric bushing is radially biased relative to the bushing and provided with a counterweight, with a through cavity with a drive shaft coaxially placed in it, connecting the support point and the distribution device, made with a counterweight, this is the center of gravity of both the counterweights and the largest rtikalnogO cross section or an eccentric sleeve walls are arranged on one side of the crusher axis in the vertical plane. The drawing shows a structural diagram of u) oklu.k,. The crusher includes a housing 1 with an outer cone 2 and a spherical support 3 for an inner movable cone 4 equipped with a shaft 5 mounted in a bearing eccentric bushing 6. The latter is equipped with a gear wheel 7 with a counterweight 8, and in the lower part has a heel 9 with a counterweight 10 the pin 11 is connected to the bushing. The ground 9 rests on the pins 12, has freedom of radial displacement relative to the bushing due to the radial groove under the pin and is fitted on its elongated shaft 5 of the cone 4 with its central bore. An intermediate Al 13 to transmit it from the torque. The intermediate shaft 13 is mounted in bearings inside the vgsha 5 and its upper end is rigidly connected with a distribution device 14 installed in the bearings on the top of the cone 4. The device is equipped with a counterweight 15. All counterweights (gearboxes, gears of the gear wheel and eccentric bushing) with The assembly is set with its centers of gravity in one vertical plane and on one side of the crusher axis. The weights of the weights and their distances from the line of action of the centrifugal force of the cone are chosen in such a way,. so that the sum of the moments of all forces and the sum of these forces itself would be zero. This condition is achieved in this design. The crusher works as follows. When the gear wheel 7 rotates, the eccentric sleeve b of fifth 9, which is connected with sleeve b by pin 11, also receives rotation. The movable cone 4 performs 3 grace movements on the spherical support, while the lower part of its shaft 5, is mounted c) the centrifugal force of the counterweight five always acts in the direction opposite to the deflection of the cone. From point 9, through the intermediate shaft 13, the rotation is transmitted to the switchgear 14, the weight of which is also directed in the direction opposite to the deflection of the cone. Thus, the centrifugal forces from the tube and the distribution tank are applied to the cone and keep it on a spherical idle idling at the proper turnovers. These same forces, together with the forces developed by the eccentric assembly, fully compensate for the centrifugal force of the cone and the moment from it. As a result, the crusher and cone separately are completely balanced. This allows you to raise the number of taper swings without a wort for reliability of the crusher, thereby increasing its technological performance and eliminating the dynamic loads on the foundation.
