Description
Technical field
The present invention relates to ore hopper field of mechanical technique, in particular to a kind of ore hopper doffer.
Background technology
Ore is the principal commodity of ore specialized marine terminal, and in Large-scale professional ore terminal, ore handling adopt ship unloaders and belt conveyor system to complete.The ore that ship unloaders grab bucket captures from cabin, is leaked by hopper and is put on the belt conveyor of belt feeder, then be transported to desired location through belt conveyor.At ore from hopper to belt conveyor until with the process of belt conveyor synchronized movement, having two kinds of phenomenons must occur, one be ore fall time be similar to free-falling body, the gravitational thrusts of generation can damage belt conveyor device, especially bracing or strutting arrangement; Two is after whereabouts ore contact belt conveyor, and the power of belt conveyor synchronized movement all comes from the friction between ore and belt conveyor, and this friction causes wearing and tearing and the inefficacy of belt conveyor.
Hopper majority now for loading and unloading ore adopts direct discharged way; minority is impacted to reduce; in feed hopper bottom, grid or multilayer striker plate are set; this impacts reduction and serves certain effect; certain protective effect is served to the bracing or strutting arrangement of belt conveyor; but also occur the deficiency that hopper blanking patency reduces, if arrange too much retaining means, the situation of hopper blocking just happens occasionally simultaneously.Key is these measures existing, all do not change velocity reversal during ore contact belt conveyor, namely speed when ore falls to touching belt conveyor is vertical with belt conveyor kinematic velocity, the rate of onset that ore moves with belt conveyor increases to the power synchronous with belt conveyor by zero, all from the friction between belt conveyor.Ore still exists belt conveyor sharp worn situation.The length of large-scale ore terminal belt delivery system all in km, belt cost at 1000 yuan/meter, due to wearing and tearing cause belt conveyor lost efficacy change cost reach millions of unit/time.This not only brings huge economic loss to enterprise, also wastes resource in a large number.
Summary of the invention
For above-mentioned problems of the prior art; the invention provides a kind of ore hopper doffer; this device carries out beneficial conversion to the speed of blanking and kinetic energy, saves the consumption of power of belt conveyer, and the ore hopper doffer of available protecting belt conveyor and bracing or strutting arrangement.
For achieving the above object, the invention provides following technical scheme:
A kind of ore hopper doffer, comprises blanking mechanism and erection seat;
