Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a feeding section that sends out paddy in one direction using an arcuate lower flow grain plate at the lower end side of the drying passage formed in the vertical direction. In a paddy dryer that is equipped with a payout roll in which a plurality of payout blades are radially attached to a rotating shaft in the payout part, the paddy is not left in the payout part when the paddy is discharged after drying. This invention relates to a device for discharging leftover rice from a feeding section for complete discharge.

[Prior Art] Conventionally, this type of paddy dryer has a structure in which a rotary valve is provided for discharging paddy from a drying passage, and an elastic plate is attached to this rotary valve to discharge the paddy so that it does not remain in the dispensing section. The one from 1986-
42283, and also published in Japanese Unexamined Patent Publication No. 1983-
This is already known as described in Japanese Patent No. 199733.

[Problems to be solved by the invention] By the way, in the rotary valve described in the above publication, an elastic plate is protruded from the feeding blade,
While the rotary valve is rotating, this elastic plate scrapes the surface of the grain plate in the lower part of the feeding section to discharge the paddy so that no paddy remains. Since the elastic plate of the valve repeatedly scrapes the surface of the lower flow grain plate, wear and tear on the elastic plate and material fatigue are significant.

For this reason, in the conventional method, when the paddy is discharged at the end of drying, some paddy remains, causing rat damage, and the remaining paddy sticks to the surface of the lower flow grain board and hardens for next use. There were problems such as making it impossible.

The present invention has been developed in view of the above-mentioned defects of the conventional products.The present invention is designed to eliminate the drawbacks of the conventional products. By installing an elastic paddy scraping plate that comes into contact with the lower grain plate only near the end of discharge, the deformation of the paddy scraping plate from warping due to wear and material fatigue can be prevented over a long period of time. It is an object of the present invention to provide a device for discharging residual paddy from a feeding section in a paddy dryer, which prevents the occurrence of drying and completely discharges paddy without leaving any paddy remaining at the end of drying.

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following technical means.

That is, on the lower end side of the drying passage formed in the vertical direction, a feeding section is formed that sends out the paddy in one direction by an arc-shaped lower flow grain plate, and within the feeding section, a plurality of feeding blades are mounted on a rotating shaft. In a device in which a feed-out roll is installed radially, the feed-out blade of the feed-out roll is housed by its own weight in the rotation trajectory of the feed-out blade during the rising process of the feed-out blade as the feed-out roll rotates, and This is a rice residue discharging device in a feeding section of a rice dryer, characterized in that an elastic rice residue scraping plate is rotatably mounted and protrudes out of the rotational trajectory during the descending process due to its own weight. be.

[Function] According to the rice residue discharging device in the feeding section of the rice grain dryer configured as described above, the rice residue scraping plate attached to the feeding blade removes the remaining rice from the feeding blade as the feeding roll rotates. In the ascending process, the residual rice scraping plate is accommodated within its rotational trajectory by its own weight, and in the descending process, it also rolls to protrude from the rotational trajectory due to its own weight. However, during the continuous discharge of paddy, the interior of the dispensing section is filled with paddy except for approximately half of the opening side in one direction, so the remaining paddy stored in the rotation trajectory of the dispensing blade during the upward movement of the dispensing blade The scraping plate receives rice grain pressure and is maintained in the same state even during the downward movement of the feeding blade. Therefore, during continuous discharge of paddy, the remaining paddy scraping plate does not come into contact with the lower flow grain plate, and the paddy is fed and discharged by the plurality of feeding blades.

On the other hand, as the paddy discharge approaches the end, the amount of paddy in the feeding section gradually decreases, and the remaining paddy scraping plate receives almost no paddy pressure during the descending process of the feeding blade, as described above. It rotates by protruding out of the rotation trajectory due to its own weight. Therefore, at this time, the remaining paddy scraping plate comes into contact with the lower flow grain plate, and the paddy remaining on that surface is scraped out and completely discharged.

[Example] An embodiment of the present invention will be described with reference to the drawings.

In the drawing, reference numeral 1 denotes a drying passage, and the drying passage 1 is formed vertically between a hot air chamber 2 and a ventilation chamber 3, and at the lower end side of the drying passage 1, there is an upper part that slopes downward. The flow grain board 4 and the arcuate lower grain flow board 5 form a feeding section 6 that delivers paddy in one direction. A horizontally elongated feed roll 7 is stored in the feed section 6 and mounted on a storage shaft.

The above-mentioned feeding roll 7 has a plurality of oblong feeding blades 9 mounted radially on a rotating shaft 8 at equal intervals, and one blade surface 10 of the plurality of feeding blades 9 has a pair of left and right blades. Bearing fittings 11, 11 are installed at appropriate intervals, and support fittings 12, 12 each having a screw hole 17 with a screw carved therein are integrally installed at opposing positions of the pair of bearing fittings 11, 11. It is installed. Reference numeral 13 denotes a leftover paddy scraping plate; the base end of the leftover paddy scraping plate 13 is clamped by a U-shaped mounting bracket 14, and the front end has a long elastic end extending in one direction. The surface of the mounting bracket 14 has a support 15, which is located close to the inside of the pair of left and right bearings 11, 11.
15 is attached by rivets 19. A pair of left and right bearings 11, 11 and a support body 15,
15 refers to the screw holes 17, 17 of the support fittings 12, 12.
Support shafts 16, 16 screwed into the support shafts 16, 16, respectively, are passed through holes 18, 18 bored on the sides of the supports 15, 15, so that the supports 15, 15 are rotatably supported with respect to the bearings 11, 11. There is. Therefore, as the feed roll 7 rotates, in the rising process of the feed blade 9, the remaining paddy scraping plate 13 is housed within the rotation locus of the feed blade 9 due to its own weight, and During the lowering process, the remaining paddy feeding plate 13 operates so as to protrude out of the rotation locus of the feeding blade 9 due to its own weight.

The rolling range of the leftover rice scraping plate 13 is between the base end 14a of the mounting bracket 14 and the blade surface 10, the counter-rotation surface 14b and the inclined edge 11a of the tip of the bearings 11, 11, 11a.
Reference numeral 20 denotes a paddy removal chamber formed on the opening side of the feeding section 6.

In the apparatus configured as described above, during drying, the feed roll 7 is rotated to sequentially feed out the paddy from the drying passage 1 for circulation drying. At the end of drying, the feed roll 7 is rotated to sequentially feed and discharge the paddy.

By the way, the remaining paddy scraping plate 13 attached to the above-mentioned feeding blade 9 is sequentially stored in the rotation locus due to its own weight during the rising process of the feeding roll 7 as the feeding roll 7 rotates, and is also stored in the rotation trajectory during the descending process. Then, due to its own weight, it rolls so as to protrude from the rotation locus. However, during the continuous discharge of paddy, the inside of the feeding section 6 is filled with paddy except for approximately half of the opening side in one direction, so that during the upward movement of the feeding blade 9, the paddy is stored within its rotational trajectory. The remaining paddy scraping board 13 is
Even during the descending process of the feed-out blade 9, the paddy is maintained in the same state due to the paddy pressure. Therefore, during continuous discharge of paddy, the remaining paddy scraping plate 13 does not come into contact with the lower flow grain plate 5, and the paddy is fed out and discharged by the plurality of feeding blades 9.

On the other hand, when the paddy discharge is almost finished, the feeding section 6
As the amount of paddy inside gradually decreases, the remaining paddy scraping plate 13 receives almost no paddy pressure even during the descending process of the feeding blade, so that it protrudes out of the rotation trajectory of the feeding blade 9 due to its own weight. Therefore, at this time, the remaining paddy scraping board 13 is replaced by the lower flow grain board 5.
Since the rice comes into contact with the surface, the rice remaining on that surface is scraped out and completely discharged.

In this way, the remaining paddy scraping board 13 contacts the lower flow grain board 5 only for a short period of time necessary for discharging the remaining paddy, so the remaining paddy scraping board 1
It is possible to prevent warping and deformation due to wear and material fatigue over a long period of time, and to completely discharge rice without leaving any residue at the end of drying.

[Effects of the invention] As described above, the present invention forms a feeding section for feeding out paddy in one direction by an arc-shaped lower flow grain plate at the lower end side of the drying passage formed in the vertical direction. In a device in which a feeding roll having a plurality of feeding blades radially attached to a rotating shaft is disposed in the feeding unit, the feeding blade of the feeding roll is rotated during the rising process of the feeding blade as the feeding roll rotates. The device is equipped with an elastic paddy scraping plate that is rotatably installed, and is stored in the locus by its own weight and protrudes out of the rotating locus during the descending process of the feeding blade due to its own weight. During continuous discharge, the leftover paddy scraping board is not brought into contact with the lower flow grain board, and is brought into contact with the lowerflow grain board only when paddy discharge is nearly finished, to prevent warping and deformation of the leftover paddy scraping board due to wear and material fatigue. can be prevented over a long period of time, and the durability of the rice scraping board is significantly improved.
It is possible to completely remove paddy without leaving it behind for a long period of time.
