Abstract

The utility model relates to a channel scraper conveyer which is a transportation machine used for underground work. The channel scraper conveyer is characterized in that a machine body and a machine tail form a tilting state, and a machine head forms a horizontal state. A speed reducer has two-stage gear transmission, and the output shaft of the speed reducer is provided with a protective motor and the device of the speed reducer. The machine tail is provided with a chain tightener for adjusting the tightness of a scraper chain. The utility model can be used for conveniently loading mineral to a mine car under complicated geological condition, and the channel scraper conveyer can be particularly matched with a scraper conveyer with a single chain.

Description

Channel scraper conveyer

The utility model relates to a kind of Transport Machinery that is exclusively used in underground work.

The transportation of general middle and small scale coal mine driving surface at present owing to be subjected to restriction such as geologic condition, is adopted the crooked slat conveyer of strand more, make this machine mine car of directly coal being packed into, and the one, need head is raised, the 2nd, it is low that the mine car road is fallen, and work difficulty is big.In some tunnel, entrucking also must be by manually finishing, and labour intensity is big, and production efficiency is low.

The purpose of this utility model provides a kind of tunnel scraper plate elevating conveyor of the mine car of can easily mineral being packed under complex geological condition.

Technical solution of the present utility model is: tunnel scraper plate elevating conveyor has the fuselage that is made of headstock, intermediate channel and aircraft tail shelf, the headstock front end is equipped with the head sprocket wheel, the tail sprocket wheel is equipped with in the aircraft tail shelf rear end, the scraper chain that is driven by the head sprocket wheel is housed on the fuselage, the motor that drives the head sprocket rotation by retarder is installed on the headstock.For reducing the fuselage height, headstock of the present utility model is a horizontal direction, becomes the obtuse angle to be connected with the intermediate channel of direction of tilt.Retarder is the secondary gear transmission, it be with one of motor shaft bonded assembly retarder on bevel gear is housed, on two of retarders vertical, be equipped with and aforementioned bevel gear ingear bevel gear with retarder one direction of principal axis, one cylindrical wheel also is housed on this axle, with three of head sprocket shaft bonded assembly retarders on be equipped with and aforementioned cylindrical wheel ingear cylindrical wheel.

The utlity model has following advantage:

1, need not raise head or fall to hanging down the mine car road, can easily the mineral on the conveyer be written in the mine car;

2, be subjected to landform restriction must tunnel by artificial entrucking in, mineral are shoveled into the entrucking voluntarily of this drive end unit, reduce labor intensity greatly;

3, simple and compact for structure, be convenient to dismounting, manoevreability is good;

4, motor and retarder are effectively protected.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1;

Fig. 3 is the utility model fundamental diagram.

Constitute headstock (4), intermediate channel (5) and aircraft tail shelf (7) three parts of fuselage, each is welded by side plate, middle plate and base plate, links together by connecting angle (6).Be contained in the head sprocket wheel (10) of headstock front end, the tail sprocket wheel (14) that is contained in the aircraft tail shelf rear end and the equal selection standard spare of scraper chain.Head sprocket wheel one end is installed on the blind axle of head pulley (15), and the other end is installed on the retarder three (19).The two ends of tail sprocket shaft are contained in the bearing on the tail bearing slide plate (9), and the tensioner bolt (8) and the tail bearing slide plate (9) that are installed in the aircraft tail shelf both sides constitute chain tensioner sheet.Scraper chain is made of round-link chain (12) and scraper plate (13).Electrical motor (3) is installed in headstock the same side with retarder (1), retarder one (25) connects with motor shaft by rigid coupling (2), retarder is the secondary gear transmission, it is on one of retarder a bevel gear (24) to be housed, on retarder two (21), be equipped with and aforementioned bevel gear (a 24) ingear bevel gear (23) and a cylindrical wheel (22), on retarder three (19), be equipped with and aforementioned cylindrical wheel (22) ingear cylindrical wheel (16).In the present embodiment, on retarder three (19), be set with hollow shaft sleeve dish (17), cylindrical wheel (16) is not directly to be contained on three of the retarders, but be fixed on the hollow shaft of hollow shaft sleeve dish (17), the end that retarder is three is equipped with exertin and cuts dish (20), and it is connected by safety plug (18) with hollow shaft sleeve dish (17).When overload load, safety plug (18) is cut dish (20) by exertin and is cut off, and the cylindrical wheel (16) on three of the retarders dallies with hollow shaft sleeve dish (17), thereby retarder and motor are protected.When scraper chain is lax, rotate tensioner bolt (8), make it promote to move behind the tail sprocket wheel (14), realize tight chain.Be fixed with on the headstock and hang handle (11), chain-drive section utilizes roundlet loop chain or wire rope hanging.

Claims

1, a kind of tunnel scraper plate elevating conveyor, comprise the fuselage that constitutes by headstock (4) intermediate channel (5) and aircraft tail shelf (7), the front end of headstock is equipped with head sprocket wheel (10), tail sprocket wheel (14) is equipped with in the rear end of aircraft tail shelf, the scraper chain that is driven by the head sprocket wheel is housed on the fuselage, the motor (3) that drives the head sprocket rotation by retarder (1) is installed on the headstock, and it is characterized in that: headstock is the horizontal surface direction, becomes the obtuse angle to be connected with the intermediate channel of direction of tilt; Retarder is the secondary gear transmission, comprise be contained in motor shaft bonded assembly retarder one (25) on bevel gear (24), be contained on the retarder two (21) with an aforementioned bevel gear ingear bevel gear (23) and a cylindrical wheel (22), be contained in head sprocket shaft bonded assembly retarder three (19) on aforementioned cylindrical wheel ingear cylindrical wheel (16).
