Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the top view that slag harrows part.
Fig. 3 is the left view that slag harrows part.
Fig. 4 is top view when two slag rakes open.
Specific embodiment
The technical solution that according to the present invention will be described in detail below with reference to the accompanying drawings:
Such as Fig. 1 to 3, a kind of dragveyer structure, including ontology and vertically-mounted rotating shaft 2 on the body, rotating shaft 2 can
It further include the slag rake 1 for being connected with the rotating shaft 2 to be turned round relative to ontology.
In general, slag rake 1 is two groups that left and right is oppositely arranged, drive of the rotating shaft 2 in driving devices such as hydraulic motor, motors
Dynamic lower drive slag rake 1 is turned round.
When fishing out slag, two groups of slags harrow 1 back rotation in opened condition, and slag rake 1 immerses after molten metal, and slag rake 1 rotates forward,
Close up poly- slag, then dragveyer structure is promoted, is mobile, and dregs are reaped target area, and slag rake 1 is again turned on, and discharges dregs.It is logical
Often, slag rake 1 also needs to open up into maximum angle progress multiple impacts, is removed dregs by way of vibration.
Slag harrows the bindiny mechanism between 1 and connecting shaft 1-1 are as follows:
1 top of slag rake is equipped with connecting shaft 1-1, and the cross sectional shape of the connecting shaft 1-1 is polygon, the rotating shaft
2 bottoms offer the connecting hole matched with the connecting shaft 1-1.
Preferably, the cross sectional shape of the connecting shaft 1-1 is rectangular, facilitates processing.Or other shapes such as hexagon
Shape.
The first horizontal pin hole is also provided on the rotating shaft 2, first pin hole connects with the connecting hole；
Level and the second pin hole corresponding with the first pin hole position are offered on the connecting shaft 1-1.
The dragveyer structure further includes mounting pin 3, and after connecting shaft 1-1 is inserted into connecting hole, the mounting pin 3 is inserted into
First pin hole and the second pin hole, to realize the connection between slag rake 1 and rotating shaft 2.
The torque that slag rake 1 is born mainly is carried by rectangular axis hole.The effect of the mounting pin 3 is carrying slag
The gravity of rake 1, therefore its cross sectional shape is preferably the rectangle that height is greater than width.
Preferably, the connecting shaft 1-1 is the tapered shaft being tapered from bottom to top, the connecting hole be with it is described
The bellmouth that connecting shaft 1-1 matches, pyramidal structure can make the handling of connecting shaft 1-1 more convenient.
Further, the mounting pin 3 can design wedgewise: the bottom surface of first pin hole is the first inclined-plane, described
The bottom surface of mounting pin 3 is the second inclined-plane being in contact with first inclined-plane；The top surface of the mounting pin 3 and second pin hole
Top surface be in contact.After being inserted into mounting pin 3, inwardly squeezed from big end, under the action of inclined-plane, the top surface of mounting pin 3 is pushed up
Dynamic connecting shaft 1-1, until the conical surface between connecting shaft 1-1 and connecting hole completely attaches to.
Further, the thinner one end of the mounting pin 3, which is opened, is additionally provided with third pin hole, the third pin hole and the mounting pin
3 is perpendicular, is equipped with lock pin 4 in the third pin hole.By being inserted into lock pin 4, it can prevent mounting pin 3 from falling off.
After dismounting repeatedly, mounting pin 3 will appear abrasion, and lock pin 4 is inserted into original position at this time and is not avoided that installation
Pin 3 not can guarantee conical surface full contact still in the state of loosening.To solve this problem, the quantity that the third pin hole is arranged is
More than two, the length direction along mounting pin 3 arranges, and after mounting pin 3 is worn, lock pin 4 is sold for mobile one to big end side
Hole insertion, it is ensured that the conical surface completely attaches to.
It needs to skim in Lao Zha in some cases, after two slag rakes 1 are flared to and spend in 180 to 200, in molten metal liquid level
On push ahead, then close up again.In progradation, dregs are easy after draining to slag rake 1 from the gap between two slag rakes 1
Side.To solve this problem, it is fixedly connected with vertical baffle 6 in the rear outside face of slag rake 1, the baffle 6 is located at connecting shaft 1-1
On rear side of lower section, baffle 6 is obliquely installed relative to front-rear direction.When 1 opening of slag rake is pushed ahead, baffle 6 blocks intermediate gap,
Prevent dregs from draining to rear side.
On the other hand, wherein being also equipped with collision block 5 on the lateral surface of one group of slag rake 1.In the case where originally there is no collision block 5,
Two slags rake 1 opens up into maximum angle when carrying out collision slagging-off, the roots of two slags rakes 1 can first contact-impact, which compares
By axial ray, crash shock effect is undesirable.After the collision block 5 for increasing protrusion, the point of impingement can be moved on to the position far from axis,
Vibration slagging-off effect is greatly improved.
