Изобретение относитс к устройствам дл |)авномерного распределени дробимого материала по окружности дроб щей полости конусной дробилки и может быть использовано в горной, химической и строительной отрасл х промышленности.The invention relates to devices for uniformly distributing crushed material around the circumference of a crushing cavity of a cone crusher and can be used in the mining, chemical, and construction industries.

Известный распределитель питани , выполненный в виде тарели, закрепленной на подвижном конусе дробилки, не обеспечивает равномерного распределени дробимого материала по гранулометрическому составу 1.The known feed distributor, made in the form of a plate fixed on the movable cone of the crusher, does not ensure uniform distribution of the material being crushed by the particle size distribution 1.

По своей технической сущности наиболее близким к предлагаемому вл етс распределитель питани конусной дробилки, содержащий установленную на подщипниках воронку с наклонным лотком, расположенную на загрузочном столе. В известном распределителе вращение воронки осуществл етс не от специального механического привода, а непосредственно от конуса дробилки , что упрощает конструкцию и снижает стоимость изготовлени аппарата 2.By its technical essence, the closest to the proposed one is the power distributor of a cone crusher containing a funnel with an inclined chute mounted on the supports, located on the loading table. In the known distributor, the rotation of the funnel is carried out not from a special mechanical drive, but directly from the crusher cone, which simplifies the design and reduces the cost of manufacturing the apparatus 2.

Однако осуществление привода от конуса не обеспечивает равномерности вращени воронки и распределени материала по кольцевой полости дробилки.However, the implementation of the drive from the cone does not ensure uniform rotation of the funnel and distribution of the material in the annular cavity of the crusher.

Цель изобретени - повыщение равномерности вращени воронки под действием реактивной силы потока материала.The purpose of the invention is to increase the uniformity of rotation of the funnel under the action of the reactive force of the material flow.

Указанна цель достигаетс тем, что в распределителе питани конусной дробилки, содержащей установленную на подщипниках воронку с наклонным лотком, расположенную на загрузочном столе, воронка снабжена соосно размещенной в ее полости втулкой , выполненной в виде пр мого усеченного конуса, а в кольцевом,зазоре между втулкой и воронкой установлена спиральна лопасть .This goal is achieved by the fact that in the power distributor of a cone crusher containing a funnel with an inclined chute mounted on the supports, located on the loading table, the funnel is provided with a sleeve coaxially placed in its cavity, made in the form of a straight truncated cone, and in an annular gap between the sleeve and the funnel is mounted with a spiral vane.

Одно- или многозаходна спираль и боковые стенки конуса и воронки образуютA single or multiple spiral and the side walls of the cone and funnel form

два винтовых желоба, по которым материал перемещаетс к разгрузочному лотку. Реактивный момент, создаваемый потоком материала , обеспечивает равномерное вращение и подачу руды в кольцевую камеру дроблени . Распределитель питани не требует специального привода, отличаетс простотой конструкции и обслуживани .two screw channels on which the material moves to the discharge chute. The reactive moment created by the material flow ensures uniform rotation and supply of ore to the annular crushing chamber. The power distributor does not require a special drive, is characterized by simplicity of design and maintenance.

Claims

FIG. 1 shows a power distributor, a longitudinal section; in fig. 2 is the same; the cross-section A-A in FIG. 1. The distributor includes 1 with a discharge chute 2 rotating in support 3 mounted on an axle 4. Axis 4 is fixed via crossheads 5 in the receiving table 6. Support 3 is mounted in a cone 7, which is rigidly connected to the walls of the funnel 1, for example a two-way spiral the blade 8; The spiral forms two screw chutes 9 and 10 inside the funnel (Fig. 2). The helical surfaces are made of individual ribs 11. Ore of the body from the receiving table, iiui., .. ic. P . -in 6, falls into two screw chutes 9 and 10, along which it simultaneously moves downward and tapers toward the outer wall of the funnel 1. Thus, provide: Гс.е ™ spreading along the inside diameter of the spiral. This leads to an increase in the circumferential flow rate of the material, and, consequently, to a more intensive outflow of material, which contributes to the stable rotation of the funnel and uniform distribution of the product throughout the crusher's ring cavity. Ensuring a uniform-steady rotation of the funnel 1 of the power distributor by the reactive moment of the material flow eliminates the installation on a 2.5 kW motor gearbox. For a factory processing 10 million tons of pounds per year, installing such power distributors on 12 KMD crushers with a working life of 8000 hours gives an annual economic effect only on electricity of 4.8 thousand rubles.
