Technical field
The utility model relates to a kind of material-contracting divide riffle, specifically a kind of many granularities of sealing low-frequency vibration riffle.
Background technology
Existing material-contracting divide riffle generally is by several wide cells the column streams to be carried out perpendicular cuts, adjacent two cell streams guiding is opposite, be cut the odd and even number section and take in respectively in two different vessels, thereby material is divided into isopyknic two parts.This material-contracting divide riffle of prior art, material-contracting divide riffle can only a kind of granularity specifications of division or the compound of the following specification material of this granularity, and the material of division different grain size specification need be changed the material-contracting divide riffle of dimension.
Be prepared as example with coal sample, the material-contracting divide riffle of prior art, can only division granularity≤13,6, the 3mm sample, and can not division≤25mm and above size sample, prepare rule according to coal sample, granularity large sample quantity is just many, artificial division operation requirements strict, loaded down with trivial details (need along material inlet length evenly and omnidistance back and forth feed), large, the division inefficiency of labour intensity, division precision be difficult for guaranteeing.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of not only labour intensity is little, division efficient is high, and high many granularities of the sealing low-frequency vibration riffle of coal material, division precision that can the multiple granularity specification of division.
In order to solve the problems of the technologies described above, many granularities of sealing low-frequency vibration riffle of the present utility model, comprise a plurality of cells that are arranged side by side on the frame and can carry out to the column streams perpendicular cuts, the top and bottom of cell respectively are provided with inlet point and discharging opening, and the streams guiding of adjacent two cells is opposite and make discharging opening be distributed in the both sides of frame; The cell that is arranged side by side is divided into two and arranges section, and the cell width of two arrangement sections are different, is respectively coarsegrain and arranges section and small grain size arrangement section; The top that the different cell of two kinds of width is arranged section be respectively arranged with one can be in arranging segment limit the feed hopper of reciprocally swinging.
Described feed hopper is driven by the reciprocating feeder structure, and described reciprocating feeder structure comprises the connecting rod simultaneously hinged with two hoppers, and connecting rod one end and crank are hinged, and drive its reciprocally swinging by the crank of rotation.
Described frame drives its vibration by a vibrating mechanism, described vibrating mechanism includes the walking beam of captiveing joint with frame, one end of walking beam is hinged on the fixed mount, the other end is pressed on the rotatable cam and upper and lower vibration under the driving of cam, also is connected the drop-down spring that promising walking beam provides elastic pulling force between walking beam and the fixed mount.
The described below that is positioned at the cell discharging opening of both sides is respectively arranged with stripper, described stripper one end is hinged on the fixed mount, stripper can be overturn, on the ground in the material guiding frame outside that stripper can fall discharging opening when tilting between level attitude and obliquity.
The cell width that described coarsegrain is arranged section is 32 mm, and the cell width that small grain size is arranged section is 9mm.The cell that coarsegrain is arranged section be used for division granularity≤25 or≤material of 13 mm, the cell that small grain size is arranged section be used for division granularity≤6 or≤material of 3 mm.
After adopting above-mentioned structure, because the reciprocating feeder structure that the feed hopper below arranges only needs material is directly toppled over along material inlet, back and forth feed is finished by reciprocating type feed hopper, and the cutting streams is more accurate, and the division precision is higher; Cell is set to two kinds of arrangement sections that width is different, the material of different grain size specification is reached the purpose of step by step division by the cutting of the cell section of different in width, do not need the step by step material of the various granularity specifications of division of any adjusting, easy and simple to handle, quick, reliably need not change any parts or device yet, improved thus work efficiency, reduce labour intensity, avoided coal sample cross pollution and dust leakage, met environmental demands.Be provided with vibrating mechanism on the frame of cell, form vibration by leaving behind rapidly by the cam jack-up of percussion mechanism and by spring, non-cakedly when making material by division do not stop up, it is more smooth and easy to fall, and has guaranteed that the larger coal sample of moisture is by smoothly division; The stripper that cell below arranges can make to be abandoned sample and directly lands, make stay, abandon sample process more convenient.
