Description

The invention relates to devices that distribute power in cone crushers, and can be used in the construction and mining industry. ·

Known power distributors for cone crushers, including a distribution funnel with an inclined bottom and a side loading window, YaV- | 0 are equipped with convenient mechanized means for uniform loading of cone crushers, which contributes to high technological and operational performance of crushers [ДЗ · is

The disadvantage of this device is the rapid wear of the bottom of the funnel. In this case, the repair of a failed funnel requires considerable labor and a long stop of the crusher. 20

In its technical essence, the closest to the invention is a cone crusher power distributor containing a distribution funnel

WITH BOTTOM AND side unloading WINDOW 2 as well as drive f2j.

In the specified power distributor, the bottom is horizontal, and the material accumulated at the bottom self-lays the bottom surface of the distribution funnel. Nevertheless, partial wear of the funnel cannot be avoided in this device, since the leading edge of the bottom remains subject to the abrasive action of the material flowing from the funnel. In addition, the overhaul period has to be reduced also because the material loaded into the crusher, as the bottom wears out, deviates more and more from a predetermined path to the center of the crusher, which violates the uniformity of its loading and worsens technological performance.

The aim of the invention is to increase the service life of the funnel and the stability of the loading process.

The specified goal is achieved by heme that in the power distributor of the cone crusher containing a distribution funnel with a bottom and a side discharge window, as well as a drive, the funnel is equipped with a tray located under its bottom with the possibility of translational movement by means of a screw pusher connected with it.

The drawing schematically shows the power distributor cone crusher, section.

A distribution funnel 1 with a bottom _t 2. and a side discharge window 3 is supported on rollers 4, one of which is driven by a drive 5. Under the bottom of the funnel in the guides 6 there is a tray 7 connected to a screw pusher 8. In the upper part of the distributor fixed motion funnel 9 with pipe 10 is installed.

The power distributor operates as follows.

The material through a fixed funnel 9 with a pipe 10 enters the distribution funnel I rotating on the rollers 4, the bottom <2 of which is self-lined with a layer of accumulated material. Crumbling under the influence of weight and centrifugal force on the receiving capacity of the crusher,

Such a solution allows to increase the turnaround time by 2–3 times and thereby reduce the operating costs of the crushing plant by 3%, as well as reduce equipment downtime by 2–5%.

With regard to a workshop with a capacity of 12 million tons of ore per year, where 12 KID-2200 crushers are installed, these advantages will make it possible to obtain an economic effect of about one thousand rubles. in year. ‘
