Abstract
The invention discloses a bidirectional belt conveyor for coal and gangue. The bidirectional belt conveyor is characterized in that a passive covering belt is arranged above a lower belt of a common belt conveyor, and two ends of the covering belt access a working position of the covering belt via non-perpendicular access bend rollers of the covering belt and then return a non-working position via vertical bend rollers of the covering belt in an access circulation manner; a gangue feeding device and a plow discharger are respectively arranged at the front end and the rear end of the working position and correspond to the covering belt; the covering belt is provided with a tensioning roller; cushion carrier rollers are arranged on the common belt conveyor and correspond to the gangue feeding device, and trough type carrier rollers are arranged on the common belt conveyor and correspond to sections of the covering belt. Original facilities and original power of the existing common belt conveyor are sufficiently utilized by the bidirectional belt conveyor to convey the raw coal and the gangue in two directions. The bidirectional belt conveyor has the advantages that the bidirectional belt conveyor is low in working energy consumption; the covering belt is simple in structure; the belt is not in direct contact with the gangue, and accordingly the service life of the belt is unaffected; the gangue cannot roll easily; the covering belt can be automatically separated from the lower belt when the gangue is not conveyed by the bidirectional belt conveyor, and original functions of the common belt conveyor are unaffected.
Description
Technical field
The present invention relates to the colliery ribbon conveyer, particularly a kind of bastard coal bidirectional belt conveyer.
Background technology
The colliery ribbon conveyer is a kind of colliery continuous conveyor tool, is commonly used to unidirectional transportation coal, during special operation, with upper band and the lower band Bidirectional transporting of ribbon conveyer.The latter generally has three kinds of situations: the one, and under operating regulation instructs, utilize the lower band of common ribbon conveyer to transport material temporarily; The 2nd, transform the ribbon conveyer structure, set up safety device, use band fortune coal, carry down the people; The 3rd, in the comprehensive mechanical coal mining operation, use shuttle belt conveyor, suspension bracket is made into two-way suspension bracket, upper band transportation raw coal, lower band transports microscler material or instrument.In addition, also having a kind of situation, is exactly for some on-the-spot demand of mining, and transports spoil with the lower band of ribbon conveyer to the goaf.But directly transport spoil with band under the ribbon conveyer, the problem such as have the not wear-resistant and spoil of belt back under ribbon conveyer, to be with easily to tumble, limited thus the use of transporting this operating type of spoil with band under the ribbon conveyer.
Summary of the invention
The objective of the invention is for band under the ribbon conveyer to transport the problems referred to above that spoil exists provide a kind of spoil not with ribbon conveyer under band contact the bastard coal bidirectional belt conveyer that is difficult for tumbling with spoil, to satisfy Production requirement.
For achieving the above object, bastard coal bidirectional belt conveyer provided by the invention comprises common ribbon conveyer; Under the common ribbon conveyer with above, be provided with cover tape unpowered, that do not separate with band under the common ribbon conveyer during load, the two ends of this cover tape pass in and out its operating position via the non-perpendicular turnover bend pulley of cover tape that is positioned at band top under the common ribbon conveyer respectively, return off-position via the vertical modified roller turnover of the cover tape circulation that is positioned at the common ribbon conveyer outside respectively again; There is respectively the spoil feeding device that is positioned at cover tape top the rear and front end of corresponding cover tape operating position and is positioned at the belt plow of cover tape bottom; Cover tape is provided with the cover tape idler roller that is used in conjunction with the vertical modified roller of cover tape; Be with corresponding spoil feeding device place to be provided with impact idler under the common ribbon conveyer, corresponding cover tape section is provided with groove profile carrier roller.
The non-perpendicular turnover bend pulley of described cover tape is made of drum shaft, steel cylinder shell and ball body; The steel cylinder shell is fixedly mounted on the drum shaft by wheel hub group and key, outside at the steel cylinder shell connects the ball base cylinder with ware shape screw, ball body is distributed on the ball base cylinder, coated outside makes the ball position of ball body location keep cylinder, and the drum shaft two ends are on the oblique chamber base plate that is fixedly mounted on common ribbon conveyer by bearing and mounting seat space.
Described ball base cylinder and ball position keep cylinder to make of oil-containing nylon.
The vertical modified roller of described cover tape is propped up by barrel shell, roll shaft and vertical modified roller and is configured to; The up and down two ends of barrel shell are connected with roll shaft with sealing ring by bearing, bearing cup, transparent cover, the upper and lower side of roll shaft respectively be positioned at vertical modified roller support lower and upper cross-member on the adjustment screw rod be connected, adjusting screw rod is threaded with nut seat on being fixedly mounted on lower and upper cross-member, there is the spacing shelves ring of belt at the barrel shell two ends, and the vertical modified roller of cover tape is fixedly mounted on the chamber base plate of common ribbon conveyer in vertical direction by vertical modified roller rack space; Described cover tape idler roller is propped up by structure idler roller barrel shell, idler roller roll shaft and the idler roller identical with the vertical modified roller of described cover tape and is configured to; The front portion that is positioned at the idler roller nut seat at idler roller adjustment screw rod is provided with spring; The cover tape idler roller matches with the vertical modified roller of cover tape on the chamber base plate that is installed in common ribbon conveyer.
The invention has the beneficial effects as follows:
1. the existing facility and the power that take full advantage of existing common ribbon conveyer carry out raw coal and spoil Bidirectional transporting, and raw coal and spoil load is balance mutually, thereby can reduce the work energy consumption;
2. the unpowered cover tape that sets, simple in structure, need not increase power-equipment;
3. bear spoil by cover tape, common belt conveyor belt does not contact with spoil, and the application life of belt is unaffected;
4. when cover tape is via non-perpendicular turnover bend pulley group, accept cover tape by the steel ball body on bend pulley surface, ball body utilizes the arbitrary directional rolling performance of self to offset cover tape along the axial displacement of bend pulley;
5. when transporting without spoil, cover tape automatically with under the common ribbon conveyer is with and is separated, and the original function of common ribbon conveyer is unaffected;
6. be positioned at that band adopts groove profile carrier roller under the common ribbon conveyer of cover tape work section, can prevent effectively that spoil from tumbling.
