Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an attachment/detachment device for a grinding rotor of a vertical grain milling machine.

The present invention is a streamlined device for attaching and removing a heavy, large-diameter grinding rotor to or from a bed plate so that it can be easily and easily attached and removed.

Conventionally, the tank connected to the top of the grain milling machine was first removed, and then the nut screw that fastened the grinding trochanter to the base plate was loosened through a cover plate to the screw at the upper end of the vertical shaft higher than the grinding trochanter, and the weight was reduced. Attachment and detachment work was difficult because the grinding roller of the object had to be lifted to the upper end of the vertical shaft and then removed.

Prior to the filing of this application, the present applicant had invented a grinding trochanter attachment/detaching device for a vertical grain milling machine in Japanese Patent Application No. 57-062946, and the present application is a further improvement of this invention. Japanese Patent Application No. 57-062946 does not attach the grinding trochanter to the base plate using a cover plate at the upper part of the grinding trochanter, but instead attaches the grinding trochanter to the base plate with the grinding trochanter mounted on the base plate. It is set on the base plate via a fixture that is fitted and clamped onto the cylindrical wall surface, and there is no need to lift the grinding roller high for removal, and the work for mounting is also extremely simple. Therefore, there is an effect that the time required for attachment and detachment is significantly shortened.

However, in order to set the grinding roller from the hollow inner cylinder portion of the grinding roller, it was necessary to remove the upper cover provided on the upper surface of the grinding roller. Therefore, in the present invention, the grain mantle is divided to expose the grinding trochanter, and the grinding trochanter can be easily removed from the pedestal by loosening the plurality of tightening screws provided upward from the bottom surface of the pedestal. , can also be worn.

In the past, it took more than half a day in some cases to attach and detach, which was complicated, but according to the present invention, the task can be conveniently completed within 30 minutes.

The present invention will be explained with reference to embodiment figures. Reference numeral 1 denotes a base plate on which a grinding rotor 2 is mounted, and the base plate 1 has a vertical shaft 3 inserted into its center, and a threaded portion 4 at the upper end thereof is screwed with a nut 5 to fix it. Said base plate 1
A grinding rotor 2 is placed on the surface, and a plurality of through holes 7 for tightening screws are arranged in a circular shape on the surface of the board 1 along the wall surface of the hollow inner cylinder portion 6. Further, a cylindrical fitting 8 is fitted into the hollow inner cylinder part 6 of the grinding trochanter 2, and its upper bent part 9 locks the upper end of the trochanter 2. A lower bent portion 10 is formed on an annular bottom wall surface 11, and a plurality of screw holes 12 for tightening fittings are arranged in a circular shape on the bottom wall surface 11, overlapping with each of the through holes 7. Each of the holes 7..., 12... is fixed to the base plate 1 by tightening with tightening screws 13. Reference numeral 14 designates an upper lid portion of the grinding roller 2, and the upper lid portion 14 is screwed and fixed to the upper bent portion 9 of the fixture 8 using small screws 15, respectively. 16 is a grain milling mantle of the grain milling machine, which is vertically divided into a plurality of parts. Reference numeral 17 denotes a base of the grain milling machine, and a rotation mechanism for the vertical shaft 3 is disposed inside the base 17, and an opening/closing door 18 is provided on one side wall of the base 17 to allow the screw 1 to be opened.
3 can be screwed in and removed from the lower part of the base plate 1.

Therefore, in order to take out the grinding wheel 2, the grain mantle 16 is disassembled and removed, and the screws 13 that fasten the fixture 8 are unscrewed, and the grinding wheel 2 is moved to a lower position. It can be taken out of the machine extremely easily by lifting it slightly from the upper end of the vertical shaft and moving it laterally. Moreover, if the above-mentioned take-out process is performed in reverse, the grinding rotor 2 can be easily stored in the machine.

Note that, of course, the shape and structure of the fixture are not limited to those shown in the drawings.
