Abstract
The utility model discloses a jigging coal picker. The jigging coal picker comprises a machine body, wherein the machine body is fixedly provided with a launder, the launder is internally provided with an overflow weir, the overflow weir is connected with a lead screw, the lead screw is externally provided with a nut, and the top end of the lead screw is provided with a driving device. According to the jigging coal picker disclosed by the utility model, by welding the launder at two sides of the machine body of the coal picker, the overflow weir can move up and down along the launder, thus the thickness of a coal bed can be freely chosen, the thickness is changed into 350-600 mm from 350 mm in prior art, and the coal type with less lump coal and more fine coal can be sorted.
Description
Technical field
The utility model relates to a kind of programing in coal preparation system, is specifically related to a kind of coal jigging machine.
Background technology
Coal jigging machine of the prior art is as shown in Figure 1; Comprise body 1 and downflow weir 3, downflow weir 3 is fixed on the body 1, and this device can only be handled lump coal and coal separation; But mostly mine coal-cutting is to adopt the mechanical type digging recently, and the granularity of coal has just had very big difference like this.First: now to overweight safety be main to mine coal-cutting, uses automated mining more, and the raw coal smalls of institute's digging is many, bulk seldom, this causes the difficulty of coal separation virtually.Second: coking is main enterprise, needs multiple bituminous coal, and this just brings the complicacy difficulty changeable with adjustment of operation to coal separation.The 3rd: the difference of coal changes, and coal preparation technique flow process malleable not causes the rate of recovery on the low side.The influence of above several respects has just obviously exposed the shortcoming of the right type coal jigging of existing XD2532---machine, and its jigging area is wide: 2500mm, long: 5600mm is 14m2 altogether, and the downflow weir of bed is fixed as 350mm.The coal sorting that this coal picker is few to lump coal, smalls is many is difficulty very, and it needs high-frequency, short arc; The lead aircraft body; The adjustment of thick bed, to fixing bed, downflow weir is difficult to operation; Bring very big pressure so just for the coal washing index, be strapped in bed to each index and formed on the angle of thin and thick.
The utility model content
The technical problem that the utility model will solve is that the height of weir plate of existing coal jigging machine is fixed, and is difficult to the coal that sorting lump coal is few, smalls is many, and a kind of coal jigging machine is provided, and can adjust the height of downflow weir.
The technical scheme of the utility model realizes in the following manner: a kind of coal jigging machine, comprise body, and be fixed with chute on the body, be provided with downflow weir in the chute, downflow weir links to each other with leading screw, and leading screw is provided with nut outward, and the leading screw top is provided with drive unit.
Said drive unit is handwheel or motor.
The utility model is welded with chute on coal picker body both sides, and downflow weir can move up and down along chute, and the thickness of bed can freely be selected like this, makes 350mm ~ 600mm into by the 350mm of prior art, but the coal that sorting lump coal is few, smalls is many.
Description of drawings
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 2, a kind of coal jigging machine comprises body 1, is fixed with chute 2 on the body 1, is provided with downflow weir 3 in the chute 2, and downflow weir 3 links to each other with leading screw, and leading screw is provided with nut 5 outward, and the leading screw top is provided with drive unit.
Said drive unit is handwheel 4 or motor.
When the utility model uses, move up and down, and then the downflow weir 3 that drive and leading screw are fixedly linked moves up and down through the drive device drives leading screw; The process that downflow weir moves; Make thickness of bed layer between 350mm ~ 600mm, to move, in the time of the raw coal of sorting dynamics≤40mm, can increase downflow weir; In the time of the raw coal 6 of sorting dynamics>=40mm, can reduce downflow weir.
Claims (2)
1. a coal jigging machine comprises body (1), it is characterized in that: be fixed with chute (2) on the body (1); Be provided with downflow weir (3) in the chute (2); Downflow weir (3) links to each other with leading screw, and leading screw is provided with nut (5) outward, and the leading screw top is provided with drive unit.
2. coal jigging machine according to claim 1 is characterized in that: said drive unit is handwheel (4) or motor.
