[0027] The multi-purpose screw conveying reducer and screw conveyor provided by the utility model are now described.
[0028] like Figure 2 and Figure 3 As shown, the first embodiment of the utility model provides a multi-purpose screw conveying reducer, including a reducer body 10 and a spacer 20, wherein the spacer 20 is connected to an end face 12 of a power output shaft 11 provided on the outer shell of the reducer body 10.
[0029] When in use, one end of the reducer body 10 is connected to the motor 31 , and the other end is connected to the outer cylinder 32 .
[0030] Compared with the prior art, the multi-purpose screw conveying reducer provided in the present embodiment has an isolation plate 20 provided on the end face 12 of the power output shaft 11 on the outer shell of the reducer body 10. During installation, the isolation plate 20 isolates the portion of the outer shell of the reducer body 10 exposed to the trough body or outer cylinder of the screw conveyor, thereby reducing or avoiding the contact between the outer shell of the reducer body 10 and the material to be conveyed, thereby reducing or avoiding contamination of the material, so that this type of reducer can be used for material transportation in the food, medicine and other industries, thereby expanding the scope of application.
[0031] like Figure 2 and Figure 3 As shown, the utility model provides a specific implementation method based on the first implementation method as follows:
[0032] The isolation sheet 20 is made of a material that will not contaminate the material to be transported, such as a stainless steel component, a plastic component, or a glass component.
[0033] The isolation sheet 20 and the reducer body 10 are connected by bonding, welding, clamping or bolting, etc., so that the isolation sheet 20 can be fixed on the end surface of the reducer body 10.
[0034] In some specific embodiments, the isolation sheet 20 is a circular sheet structure. An inner hole for the power output shaft 11 of the reducer body 10 to pass through is provided in the middle of the isolation sheet 20. The reducer body 10 is provided with a sealing cover 13 that is sealed and connected to the power output shaft 11. The sealing cover 13 is connected to the end face 12, and the edge of the inner hole is located between the sealing cover 13 and the end face 12. In this form, the isolation sheet 20 can be clamped and fixed by the sealing cover 13 and the end face 12 to reduce the possibility of the isolation sheet 20 falling off.

[0036] In this way, the isolation sheet 20 can be better fixed on the end face 12 of the reducer body 10, which can prevent the edge of the isolation sheet 20 from warping, and is conducive to keeping the isolation sheet 20 installed flat and improving the isolation effect.
[0037] In other specific embodiments, the isolation sheet 20 is connected to the reducer body 10 by bonding, and the isolation sheet 20 is provided with a plurality of concentric annular glue containing grooves and a plurality of radially arranged glue overflow grooves, and the glue containing grooves and the glue overflow grooves are connected. During bonding, adhesive is applied inside the isolation sheet 20, and the isolation sheet 20 is pressed on the end face of the reducer body 10, and the glue containing grooves and the glue overflow grooves are used to discharge air and excess glue.
[0038] like Figure 1 As shown, based on the same inventive concept, an embodiment of the present application also provides a screw conveyor, comprising a screw conveyor body and the above-mentioned multi-purpose screw conveying reducer arranged on the screw conveyor body.
[0039] Compared with the prior art, the screw conveyor provided in this embodiment can reduce or avoid contamination of materials by providing the above-mentioned multi-purpose screw conveying reducer, and can be used for material transportation in the food, pharmaceutical and other industries, which is conducive to expanding the scope of application.
