Embodiment
Illustrative embodiments of the present utility model are described in detail with reference to the accompanying drawings.To illustrative embodiments
Description merely for the sake of demonstration purpose, and be definitely not to the utility model and its application or the limitation of usage.
As shown in figure 1, the slack adjuster of the present utility model for grain scrapper conveyor flight chain includes：Adjust silk
Bar 1, adjusting nut I2, screw rod bracket 3, adjusting nut II4 and bearing plate 5.Bearing plate 5 is arranged in frame 6, for pacifying
Fill sprocket shaft bearing (not shown)；Screw rod bracket 3 is arranged in frame 6, through hole is provided with screw rod bracket 3 (in figure not
Show)；Regulation screw mandrel 1 one end be arranged on bearing plate 5, the other end through through hole stretch to screw rod bracket 3 back in axle
The side of bearing plate 5；Adjusting nut I2 and adjusting nut II4 is separately positioned on the both sides of screw rod bracket 3 and with adjusting the spiral shell of screw mandrel 1
Line connects.
In the embodiment show in figure 1, regulation screw mandrel 1 is arranged on the left side of bearing plate 5.Those skilled in the art can be with
According to be actually needed will regulation screw mandrel 1 be arranged on the other positions of bearing plate 5, such as be arranged on bearing plate 5 upside,
Right side or downside etc., the utility model is not especially limited to this.In the embodiment show in figure 1, if scratch board machine chain is tensioned
Degree is inadequate, can be by the segment distance of adjusting nut I2 side direction turns to the left one, due to having screw rod bracket on the left of adjusting nut II4
3 keep out so that whole bearing plate 5 can only move right, bearing plate 5 move right after again by adjusting nut II4 to the left
Side direction turn, until adjusting nut II4, which is contradicted, arrives screw rod bracket 3.By by adjusting nut I2 and adjusting nut II4 to left-handed
It is dynamic, the centre-to-centre spacing of two sprocket shafts can be increased, so as to add the rate of tension of flight chain.Conversely, such as scraper chain tension, can
By adjusting nut I2 and adjusting nut II4 turns to the right so that bearing plate 5 is moved to the left, and scraper chain pine is reduced so as to reach
The purpose of tightness.
In order to prevent adjusting nut I2 and adjusting nut II4 from moving to from the side of through hole the opposite side of through hole, through hole
Radial dimension is less than adjusting nut I2 and adjusting nut II4 radial dimension.The radial direction of through hole refers to from logical in the utility model
The direction at through hole edge is pointed at hole center, and wherein through hole center refers to through hole place plane and the intersection point of the regulation axis of screw mandrel 1.
The shape of through hole can be according to being actually needed or processing conditions is selected.In some implementations of the present utility model
In example, the shape of through hole is made up of straight line and/or camber line, for example through hole is shaped as circular, triangle or sector etc..As long as
Adjusting nut I2 and adjusting nut II4 can not move to the opposite side of through hole from the side of through hole, and the utility model is to logical
The perforated area or shape in hole are not especially limited.
If not in the same plane, bearing plate 5 follows regulation screw mandrel 1 for the axis of regulation screw mandrel 1 and the axis of sprocket shaft
It may be rotated during moving together, influence the stability and reliability in scrapper conveyor running.Therefore, at this
In some embodiments of utility model, adjust screw mandrel 1 axis and sprocket shaft axis be generally aligned in the same plane in.Adjust screw mandrel 1
Axis can be vertical with the axis of sprocket shaft or intersect, as long as regulation screw mandrel 1 can change along its axial movement
Position of the bearing plate 5 on the regulation axis direction of screw mandrel 1.In some preferred embodiments of the present utility model, in order to
Simplify the structure of slack adjuster as far as possible, the axis of the axis and sprocket shaft that adjust screw mandrel 1 is mutually perpendicular to.
One end of regulation screw mandrel 1 can be fixedly provided on bearing plate 5, such as one end of regulation screw mandrel 1 is welded on
On bearing plate 5.Those skilled in the art can also be such that one end of regulation screw mandrel 1 is removably disposed on bearing plate 5, example
The one end and bearing plate 5 for such as adjusting screw mandrel 1 are removably joined together by form fit or connector.
In some embodiments of the utility model, slack adjuster may further include：It is arranged in frame 6
First locating part 7, for limiting original position and the final position that bearing plate 5 moves along the regulation axis direction of screw mandrel 1.
Slack adjuster can further include：The second locating part 8 being arranged in frame 6, for limiting bearing
Seat board 5 is perpendicular to the position of the regulation axis of screw mandrel 1 and sprocket shaft axis direction.In the embodiment show in figure 1, second is spacing
Part 8 can fixing bearing seat board 5 perpendicular to regulation the axis of screw mandrel 1 and sprocket shaft axis direction position, prevent bearing plate 5
Upper and lower play.
Preferably, the other end for adjusting screw mandrel 1 is provided with the 3rd locating part, for limiting regulation screw mandrel 1 along its axis side
To the final position towards the movement of regulation screw mandrel 1 one end.By taking Fig. 1 as an example, if turn amount is excessive to the left by adjusting nut I2, it is easy to
Come off from regulation screw mandrel 1, moved right so as to which regulation screw mandrel 1 can not be limited, cause tensioning to be failed.If in regulation screw mandrel 1
Left end sets the 3rd locating part, then can avoid the generation of the above situation.Those skilled in the art can set the 3rd locating part
Put in the peripheral side of the regulation other end of screw mandrel 1, be either arranged on or adjust on the end face of the other end of screw mandrel 1, Huo Zheqi
His position, it can only can play the stop bit that limitation limitation regulation screw mandrel 1 moves along its axis direction towards regulation screw mandrel 1 one end
The effect put.
Slack adjuster of the present utility model can be assembled as follows：First regulation screw mandrel 1 is welded on
On the positioning hole of bearing plate 5, adjusting nut II4 is then screwed in into regulation screw mandrel 1, regulation screw mandrel 1 is penetrated into screw rod bracket 3,
Adjusting nut I2 is then screwed in into regulation screw mandrel 1, whole device just assembles completion.
Compared with prior art, it is elastic can to adjust flight chain for slack adjuster of the present utility model, and structure
Simply, easy for installation, stability and reliability are high.
Although the utility model is described with reference to illustrative embodiments, but it is to be understood that the utility model
The embodiment be described in detail and shown in text is not limited to, in the feelings without departing from claims limited range
Under condition, those skilled in the art can make various changes to the illustrative embodiments.
