Description

[Detailed Description of the Invention] This invention relates to a polishing trochanter replacement device for a vertical rice mill that facilitates replacing the polishing trochanter that is consumed.

A grinding wheel called a Kongo roll is generally used for the polishing trochanter of a vertical rice mill. This white trochanter wears out after long-term use and must be replaced with a new one.

Traditionally, the rice milling machine had to be disassembled to replace the milling trochanter, but vertical rice mills have a large rice milling tank at the top, and large machines have a height of about 8 meters above the ground. Therefore, removing the rice milling tank would be a very large-scale task, requiring work at heights using cranes, chain blocks, etc., which would be extremely dangerous and time-consuming, and operations would be suspended during that time. This would have resulted in a huge economic loss.

The present invention is intended to solve these conventional problems and to enable quick and easy replacement of the refined trochanter, and will be described below with reference to the accompanying drawings showing embodiments.

The upper rice milling tank 1 is supported by the upper extension 3 of the frame 2, and the milling chamber shell 5, 5a houses the milling trochanter 4 located directly below the rice milling tank 1.
is divided into two vertically, and a refined trochanter shaft 6 and a refined trochanter shaft flange 6a are fixed to the ends of the lower drive shaft 7.
and the drive shaft flange 7a to transmit rotation, remove at least one of the halves of the milling chamber shells 5, 5a, and connect the milling trochanter shaft flange 6a and the drive shaft flange 7a. By removing the connection, the whitening trochanter block A can be taken out of the machine and the whitening trochanter 4 can be replaced.

In order to remove at least one of the two halves of the milling chamber shells 5 and 5a, the connection with the rice milling tank 1 is first removed. A cylindrical shutter 8 is configured to close the gap between the lower end of the rice polishing tank 1 and the upper end of the milling chamber shells 5 and 5a, and is configured to be able to slide up and down with the cylindrical shutter 8. The mounting bolts 9 to the shells 5, 5a are removed and the rice polishing tank 1 is slid up to the outer periphery of the small diameter cylindrical portion at the lower end of the rice polishing tank 1 to form a gap S as shown in FIG.

Next, when the mounting bolts 10 attached to the frame 2 around the lower end of the milling chamber shell 5 and the sewing bolts 11 sewn together in half are removed, one of the milling chamber shells 5 is removed as shown in FIG. Can be removed. Next, the polished trochanter shaft flange 6a and the drive shaft flange 7a.
When the connecting bolts 12 connecting the two are removed, the white trochanter block A, in which the white trochanter 4 and white trochanter shaft 6 are integrally assembled, can be taken out of the machine as shown in FIG.

After taking out the whitening trochanter block A, remove the locking nut 13 at the upper end, remove the trochanter presser 14, remove the whitening trochanter 4 upwards, and replace it with a new whitening trochanter.

Then, when it is reassembled, the replacement of the white trochanter is completed.

This refined trochanter 4 is shown in one piece in Figure 2, but for manufacturing reasons, it may be divided into two or three stages and stacked, and even in this case, they can be removed sequentially from the top. , just stack them one on top of the other from the bottom.

Although the rice milling tank 1 is supported by extending the frame 2 of the rice milling machine upward, the present invention is not limited to this.
It is also possible to support it from the floor by another building, or by attaching an appropriate support device to pillars, beams, girders, trusses, etc. of the building.

As explained above, in this case, the milling trochanter can be taken out and replaced by simply removing a few bolts, so there is no need to remove the upper rice milling tank in a large scale as in the past. The replacement work of the white trochanter, which used to require about 100 yen, can be significantly shortened to about 0.2 man-hours, and the replacement work is extremely easy and without danger. This has great effects, such as being able to significantly reduce the costs required.
