Problems solved by technology

This kind of conical rotor assembled from multiple tile-shaped rotor pieces has the disadvantages of difficulty in processing and mechanical installation, and short service life of the rotor. Moreover, because the conical rotor has splicing seams, the surface structure of the rotor is inconsistent, resulting in corn removal. The quality of skin and degerm is low

Embodiment 1

[0028] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the bump-type conical rotor of the present invention includes a rotor body, and the outer surface of the rotor body is distributed with raised crushing columns 1 integrated with the rotor body, and the rotor body is integral.

[0029] The rotor body has a two-layer structure with an inner core layer 2 and an outer layer 3, the inner core layer is made of gray cast iron, and the outer layer is made of wear-resistant cast iron.

[0030] The casting sand mold of the bump-type conical rotor includes a lower box 4, a middle box 5 and an upper box 6; the upper box is provided with a pouring port 7 and an exhaust port 8; the inner wall of the middle box is provided with a There are concave points 9 corresponding to the pulverizing columns on the surface of the rotor body.

[0031] A circular depression is provided at the center of the lower box; a circular inner core positioning ring 10 is placed at the circula...

Embodiment 2

[0043] Such as Figure 4 , Figure 5 , Image 6 , Figure 7As shown, the bump-type conical rotor of the present invention includes a rotor body, and the outer surface of the rotor body is distributed with raised crushing columns 1 integrated with the rotor body, and the rotor body is integral.

[0044] The casting sand mold of the bump-type conical rotor includes a lower box 4, a middle box 5 and an upper box 6; the upper box is provided with a pouring port 7 and an exhaust port 8; the inner wall of the middle box is provided with a There are concave points 9 corresponding to the pulverizing columns on the surface of the rotor body.

[0045] The difference between the casting mold of the conical rotor in Embodiment 2 and Embodiment 1 is that the bottom of the pressing cone 13 is provided with a screw hole. Others are the same as in Embodiment 1, and the specific structural diagram is omitted.

[0046] The manufacturing method of the casting sand mold of the bump type conic...

Abstract

The invention provides a tapered rotor, as well as a cast sand mould, a swage die and a modeling method thereof. The tapered rotor comprises a rotor body, wherein bulged smashing columns integrated with the rotor body are distributed on the outer surface of the rotor body; the rotor body is integral. The tapered rotor is simpler in mechanical installation, long in service life, convenient for control over corn peeling and degerming technology, and higher in processing quality; in addition, the invention further provides the cast sand mould, the swage die and the modeling method of the tapered rotor.

Description

technical field [0001] The invention relates to the field of grain machinery processing and manufacturing, in particular to a conical rotor in grain crushing and processing machinery, casting sand molds, molds and molding methods thereof. Background technique [0002] In grain processing, especially corn peeling and degerming processing machinery, the outer surface of the rotor rotating in the processing chamber is regularly distributed with bumps. In the prior art, due to the reason of processing technology, the rotor is cast and molded with multiple tile-shaped rotor pieces fixed on the rotating shaft and assembled to form a conical shape. This kind of conical rotor assembled from multiple tile-shaped rotor pieces has the disadvantages of difficulty in processing and mechanical installation, and short service life of the rotor, and because the conical rotor has splicing seams, the surface structure of the rotor is inconsistent, resulting in corn removal. The quality of sk...
