Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a root vegetable peeling and washing machine that has a peeling roll such as a roll brush or a metal roll with abrasive particles attached to the surface disposed inside the tank. It is something.

(Prior art) A large number of peeling rolls are installed inside a tank body to which washing water is supplied, and while these peeling rolls are rotated in a fixed direction by a drive chain, root vegetables are thrown into the tank body. A root vegetable peeling and cleaning machine for peeling and washing root vegetables has been known in the past, as shown in Japanese Utility Model Application Publications No. 176791/1983 and Japanese Patent Application No. 176792/1989 filed by the present applicant. Are known. However, in such a root vegetable peeling and washing machine, the peeling roll has a long shaft on the drive mechanism side, and a stepped small diameter part is used to peel the peeling roll because it is necessary to attach a sprocket for winding the drive chain around the shaft on the drive mechanism side. It is formed at the front of the roll shaft and the inner ring of the bearing is fitted into the small diameter part to prevent it from coming off, so if you try to flip the peeling roll left and right and have it pivoted on the bearing, the installation position will shift. There was a problem. As a result, rotation of the peeling roll in a certain direction can cause curls in the brush, and in the case of metal rolls, only one side of the edge wears unevenly, making it difficult to replace the expensive peeling roll in about 6 months. In addition to the problem of increased running costs as the peeling roll must be replaced, the peeling roll is supported by bearings attached to the tank body, so the bearings are easily corroded by the washing water and must be replaced in a short period of time. As mentioned above, there was also the problem of an unavoidable increase in running costs.

(Problems to be solved by the invention) This invention solves the above-mentioned conventional problems, significantly extends the life of the peeling roll and bearings compared to conventional products, and reduces running costs. This machine was developed for the purpose of cleaning and peeling root vegetables.

(Means for Solving the Problems) The present invention consists of a bottomed bearing in which a bearing and a seal plate are provided near the entrance of a bearing case having a deep recess on the outer wall of a tank, and a relatively shallow bearing with a through hole. A plurality of sets of bottomless bearings each having a bearing and a seal plate are installed in a case facing each other, a peeling roll is supported between these bearings, and a drive mechanism is provided at the end of the shaft passing through the bottomless bearing. It is characterized by this.

(Embodiment) Next, the present invention will be described in detail with reference to the illustrated embodiment. Reference numeral 1 denotes a tank body equipped with a cleaning water spray nozzle 2 at the top, and inside thereof a plurality of peeling rolls 3 are arranged in parallel. It is set in. The peeling roll 3 has long shafts 12 protruding from both ends.
As shown in the figure, these peeling rolls 3 have a bottomed bearing 4 attached to the removable outer wall of the tank body 1, and a bottomless bearing attached to the opposite outer wall opposite thereto. 5 and is supported by.

As shown in FIG. 3, the bottomed bearing 4
is a metal bearing case 7 with a deep recess 6
A bearing 8 is fitted on the inner surface near the entrance of the bearing case 7, and a disc-shaped seal plate 10 is fitted on the inner surface of the flange portion 9 of the bearing case 7. The seal plate 10 has a ring-shaped oil seal 11 attached to the inside of a corrosion-resistant metal plate such as stainless steel, and the shaft 12 of the peeling roll 3 is fitted inside this, and the bearing 8
This rotatably supports the peeling roll 3 and prevents cleaning water from entering the bearing 8. A bolt 13 is provided on the end face of the bearing case 7 for extracting the shaft 12 from the bottomed bearing 4 when replacing the peeling roll 3.

On the other hand, as shown in FIG. 4, the bottomless bearing 5 has a bearing 15 provided in a relatively shallow bearing case 14 having a through hole in the center, and a seal plate 16 provided at the entrance of the bearing case 14. The plate 16 is also a corrosion-resistant metal plate with an oil seal 17 attached to the inside thereof. The bottomless bearing 5 supports the shaft 12 of the peeling roll 3 in a penetrating state as shown in the figure.
As shown in FIG. 1, a drive mechanism such as a gear 18 is attached to the penetrating end of the drive chain 1.
9 rotates the peeling roll 3 in a fixed direction. In the illustrated embodiment, a combination of a brush roll and a metal roll is used as the peeling roll 3, but the type of the peeling roll 3 is not particularly limited.

(Function) The device configured as described above peels root vegetables placed in the tank while rotating the peeling roll 3 in a fixed direction within the tank body 1 as in the conventional case. When used for a long period of time, if the peeling roll 3 is a brush roll, it will become bent, and if it is a metal roll with edges, uneven wear will occur on only one side of the edges, as in the past. However, in this invention, the peeling roll 3
Since the length of the shaft is long enough to attach the drive mechanism, the drive mechanism at the end of the shaft 12 of the peeling roll 3 is removed, and the bolt 13 is rotated to remove the drive mechanism from the deep recess of the bottomed bearing 4. Push out the shaft 12 of the peeling roll 3 fitted in the tank 1, and push out the shaft 12 of the peeling roll 3 together with the removable outer wall of the tank body 1 while the other shaft 12 of the peeling roll 3 is pivotally supported by the bottomless bearing 5. Remove peeling roll 3. Next, the shaft 12 of the peeling roll 3 is pulled out from the bottomless bearing 5 on the outer wall, and the peeling roll 3 is turned over left and right. Then, the shaft 12, which had been housed in the bottomed bearing 4, is penetrated and supported by the bottomless bearing 5 attached to the outer wall. Further, the shaft 12 on the side where the drive mechanism was previously attached is inserted into the deep recess 6 of the bottomed bearing 4 to be positioned and held. From there, an outer wall to which a bottomless bearing 5 on which a peeling roll 3 is pivotally supported is attached to the tank body 1, and a drive mechanism is attached to a shaft 12 extending from the bottomless bearing 5. As a result, the peeling roll 3 can be reinstalled into the tank body 1 with its left and right sides reversed, so the edge on the side where uneven wear etc. has not occurred can be used effectively, and the peeling roll 3 can have a long life. can be doubled.

In addition, in the present invention, a bottomed bearing 4,
Bearings 8 and 15 along with bottomless bearing 5
Since the bearings are sealed by the seal plates 10 and 16, it is difficult for cleaning water to enter, and the bearings will not corrode even if used for a long time.

(Effect of the invention) As is clear from the above explanation, the present invention provides a deep recess in the bearing case of the bottomed bearing that pivotally supports the peeling roll, and a through hole in the bearing case of the bottomless bearing. Since it is relatively shallow, one shaft of the peeling roll, which has a length for attaching the drive mechanism, is passed through the bearing case of the bottomless bearing, the shaft end is extended outside, and the shaft end is Attach the drive mechanism, and similarly, the shaft of the peeling roll, which has a length for attaching the drive mechanism, is housed in a bearing case that has a deep recess with a depth equal to the length for attaching the bottomed bearing. Because of this, the peeling roll can be installed in the appropriate position even if it is turned left and right, and the life of the peeling roll can be much longer than that of conventional products. By bringing the shaft end of the peeling roll into contact with the bottom of the bearing case, which has a recess, the peeling roll can be positioned, which prevents the installation position of the drive mechanism from shifting and prevents drive failures due to misalignment with each drive mechanism. In addition, since the shaft end of the peeling roll is supported not only by the bearing but also by a deep recess, the deflection of the peeling roll is suppressed and vibrations during peeling are reduced. It has many advantages, such as being able to prevent the occurrence of peeling defects and peeling defects. Therefore, the present invention has extremely great practical value as a root vegetable peeling and washing machine that eliminates the problems of the conventional method.
