Technical Field

The utility model belongs to the technical field of the screw axis, concretely relates to removable screw axis.

Background

The existing spiral shaft is generally of an integral structure, and shaft heads at two ends are spirally welded with the middle part. The screw shaft is inconvenient to disassemble, when the screw shaft needs to be replaced, the bearing, the check ring, the reduction gearbox and the like connected with the shaft heads at the two ends need to be disassembled, and the shaft can be disassembled for a long time; when the middle part of the screw is seriously worn and needs to be disassembled for maintenance, the parts needing to be disassembled are more, the workload is large, and the cost is higher.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above-mentioned technical problem and provide a removable screw axis, the spiral section at convenient to detach middle part, the mode location effect of connecting through the tang is good, is convenient for install fast.

The utility model provides an above-mentioned technical problem's technical scheme as follows: removable screw axis includes: the driving shaft head, the middle part spiral section and the supporting shaft head, the both ends of the middle part spiral section are all connected through flange connection structure the driving shaft head with the supporting shaft head, flange connection structure includes first flange board and second flange board, the both ends of the middle part spiral section all are equipped with the second flange board, the driving shaft head is close to one of middle part spiral section is served and the supporting shaft head is close to all be equipped with on the middle part spiral section other end first flange board, first flange board with the second flange board passes through bolted connection, be equipped with the tang on the first flange board, be equipped with on the second flange board with tang complex female tang.

Has the advantages that: the spiral section in the middle part is convenient to detach, the positioning effect is good through the mode of spigot connection, and the quick installation is convenient.

On the basis of the technical scheme, the utility model discloses can also do following improvement.

Furthermore, the second flange plate is provided with an ejection piece for ejecting the first flange plate.

The beneficial effect of adopting the above further scheme is: the middle spiral section can be quickly separated from the driving shaft head and the supporting shaft head, and the subsequent maintenance of the middle spiral section is facilitated.

Further, the ejection piece is an ejection bolt.

The beneficial effect of adopting the above further scheme is: simple structure, and the disassembling work can be completed only by screwing the screw with a tool.

Further, the outer wall of the middle spiral section is provided with spiral blades.

The beneficial effect of adopting the further scheme is that: the material conveying is convenient to complete, and the stirring, mixing and other effects are achieved.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Examples

As shown in fig. 1-2, this embodiment provides a detachable screw shaft, which includes a driving shaft head 1, a middle spiral section 2 and a supporting shaft head 3, where there are helical blades 9 on the outer wall of the middle spiral section 2, the two ends of the middle spiral section 2 are connected through a flange connection structure, the driving shaft head 1 and the supporting shaft head 3 are connected through a flange connection structure, the flange connection structure includes a first flange plate 4 and a second flange plate 5, the two ends of the middle spiral section 2 are provided with the second flange plate 5, the driving shaft head 1 is close to one end of the middle spiral section 2 and the supporting shaft head 3 is close to the other end of the middle spiral section 2 is provided with the first flange plate 4, the first flange plate 4 is connected with the second flange plate 5 through bolts 10, a male end 6 is provided on the first flange plate 4, a female end 7 matched with the male end 6 is provided on the second flange plate 5, and the male end 6 and the female end 7 are convenient for centering.

In this embodiment, the number of the bolts 10 between the first flange plate 4 and the second flange plate 5 is plural, preferably 8, but not limited to the number, 8 bolt through holes are circumferentially distributed on the second flange plate 5, and the first flange plate 4 is a blind hole with a corresponding number.

In this embodiment, the second flange plate 5 is provided with an ejection member for ejecting the first flange plate 4, and the ejection member is an ejection bolt 8, and is conveniently disengaged from the spigot through cooperation of the ejection bolt 8.
