Abstract
The utility model relates to a front excavating apparatus of a railway screen scarifier, comprising a screen box, a driving device, and a raking chain and raking teeth of an excavating mechanism. The driving device is provided with a triangular girder, three shafts and three wheels; a motor is connected with a driving sprocket through a speed changer, the driving sprocket is connected with a driven sprocket, the driven sprocket is connected with a tension sprocket, and the driven sprocket and the tension sprocket are positioned on the same horizontal plane. A supporting plate is arranged between the driving sprocket and the driven sprocket, and a recovering barrel is arranged between the driving sprocket and the tension sprocket. A ballast conveying pitch angle is adjusted through a revolving hinge and an adjusting screw rod. The apparatus has the advantages of adjustable ballast conveying pitch angle, low worker labor intensity, high work efficiency, etc.
Description
The utility model relates to the leading excavating gear of a kind of railway screen scarifier, belongs at the bottom of the pillow of electric railway and excavation machinery that the side slope ballast cleaning uses.
At the bottom of the pillow of electric railway at present and the III type screen scarifier that uses of side slope ballast cleaning, the connection kind of drive of its running part is that motor drives drive sprocket by speed change gear, drive the driven sprocket rotation by taking off chain, the grilled teeth drive side slope ballast aggregate of taking off on the chain is transported to ad-hoc location with certain speed, send into screen box by the slepper-bottom digging mechanism drive, carry out cleaning by the sieve band in the screen box, whole leading part is connected with the screen box front through crossbeam.Its weak point is that the existence of the defeated quarrel inclination alpha of leading digging mechanism is restricted excavation depth, digging mechanism exist excavation less than the dead angle so that influence the walking of clear, vexed car phenomenon appears.If make inclination angle such excavation surface step-down that diminishes, but shipping height is not enough, ballast aggregate can not be gone into the screen box mouth, packing phenomenon occurs, and a large amount of ballast aggregates is clawed again and takes back, circulation so repeatedly, and digging efficiency is extremely low.In addition, during excavation, though ballast drives upwards by taking off grilled teeth on the chain that transportation has certain speed, be subjected to the influence of gravity and other factor, still some ballast aggregate drops, and stops advancing of back screen box.Grilled teeth can be taken away some ballasts to backhauling when changeing in addition, be dropped into screen box before, cause ballast aggregate to pile up, must manually remove.Defeated quarrel inclination alpha is fixed, and can not adjust the needs that do not satisfy site operation flexibly.
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art and a kind of three three-wheel transmissions are provided, install recovery cylinder between driving wheel and the expansion tightening wheel additional, defeated quarrel inclination alpha can be adjusted, high efficiency, the leading excavating gear of railway screen scarifier of the quarrel of being scattered.
The purpose of this utility model is achieved in that it comprises screen box, transmission mechanism, digging mechanism take off chain, grilled teeth, its structural feature is that transmission mechanism is set to three cantilevered corner beams, three three-wheels, wherein motor links to each other with drive sprocket through speed change gear, drive sprocket links to each other with driven sprocket, and driven sprocket links to each other with the tensioner sprocket wheel, and driven sprocket and tensioner sprocket wheel are positioned on the same level board face; Between drive sprocket and the driven sprocket supporting plate is installed, between drive sprocket and the tensioner sprocket wheel recovery cylinder is housed; Defeated quarrel inclination angle is by swing hinge and adjust the screw mandrel adjustment.
Compared to existing technology, the utlity model has following advantage:
1, adopt three cantilevered corner beams, three three-wheel transmissions, there is not the dead angle in excavation, can greatly satisfy the excavation depth requirement, and screen scarifier advances and is not obstructed.
2, when work, the no ballast road of loosing does not need artificial removing, has alleviated working strength of workers.
3, defeated quarrel tilt adjustable is adjusted into about 10 ℃, has avoided not meeting problems such as construction requirement by the excavation depth that foozle and other reason cause.
4, high efficiency adapts to the site operation needs, and the consumable accessory turnover rate is low, saves cost, has reduced the time of reprocessing.
The explanation of accompanying drawing drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the right view of Fig. 1.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model is that improved position is leading excavation part to the improvement of existing III type screen scarifier.Design philosophy is to change the diaxon of prior art, two wheel drive mechanisms into three cantilevered corner beams, three three wheel drive mechanisms.Its three cantilevered corner beams are installed in the front portion of screen box.Driving shaft, driven shaft, tension shaft are installed on three cantilevered corner beams.Wherein motor (8) links to each other with drive sprocket (1) on being loaded on driving shaft through speed change gear, drive sprocket (1), and driven sprocket (3), tensioner sprocket wheel (6) is connected through taking off chain, and driven sprocket (3) and tensioner sprocket wheel (6) are at grade.The purpose of this set is to make excavation not have the dead angle, satisfies the requirement of the control pick degree of depth.Between the drive sprocket of taking off chain (4) (1) and driven sprocket (3), supporting plate (2) is installed in addition.The effect of supporting plate (2) is to hold grilled teeth (5) to take off the ballast of side slope, ballast is not lost, in order to increase work efficiency in transportation.Grilled teeth (5) is installed in to be taken off on the chain (4), takes off chain (4) and is placed on driven sprocket (3), the tensioner sprocket wheel (6).Link to each other with screen box (10) through crossbeam (14).Its defeated quarrel inclination angle is by swing hinge (9) and adjust leading screw (13) adjustment, about α=10 ℃, guarantee so defeated be cut highly constant, the purpose that excavation depth is adjustable.
The course of work of the present utility model: motor (8) drives drive sprocket (1) through gear, through driven sprocket (3), tensioner sprocket wheel (6) drives and takes off chain (4), grilled teeth (5) is finished the ballast excacation, because driven sprocket (3) and tensioner sprocket wheel (6) are at grade, make excavation not have the dead angle, satisfy the excavation depth requirement, screen scarifier advances and is not obstructed.Supporting plate in the running (2) is held the ballast that grilled teeth (5) is taken off, and ballast is not lost in transportation.Carry out cleaning and enter screen box (10).The ballast that grilled teeth (5) is taken back all turns back to expansion tightening wheel (6) next door through recovery cylinder (7), is taken off away by grilled teeth (5) again, need not artificial removing.According to the requirement of excavation depth, can adjust screw mandrel (13) and adjust defeated quarrel inclination alpha by adjusting swing hinge (9), in the scope about α=10 ℃, adjust.Swing hinge (9) connects screen box (10) and leading digging mechanism.
