Description

[Detailed description of the invention] (Industrial application field) The present invention is a sorting device for potatoes, onions, etc., in which a rotary disk is installed directly below sorting rollers arranged in parallel at appropriate intervals. This relates to a scraping board for scraping off soil and sand that has adhered to the disc part of the machine.

(Prior Art) As shown in FIG. 5, a conventional earth and sand scraping plate includes a claw plate 10 in which a substrate M of an appropriate length is provided with a recess 10a into which a disk portion 3b of a rotary disk 3 of a sorting roller B is rotatably inserted. is attached so as to be slidably adjustable as the distance between the rotary disks 3 changes.

Therefore, if the distance between the rotary disks 3 changes depending on the size of the harvest, each claw piece 1
Since 0 had to be slid, it took a lot of effort and time, and had the drawback of poor workability.

(Problem to be Solved by the Invention) The problem to be solved by the invention is to make it possible to easily match the dirt scraping plate to the rotating disc in the sorting roll as the distance between the rotating discs changes. It is to do so.

(Means for solving the problem) A means for solving the above problem is to form a notched recess in the shape of a comb along the entire length of one long side of the strip plate, and to form a notched recess along the entire length of the other long side of the strip plate. A notch recess having a pitch different from the notch recess is formed in the shape of a comb, and an attachment shaft is provided at the center of the short side on both sides of the strip to form an earth and sand scraping plate, and the earth and sand scraping plate and the sorting roll are connected to each other. By installing the soil scraping plate directly under the soil scraping plate, the soil scraping plate scrapes off the soil adhering to the disc portion of the rotary disk in the sorting roll during the sorting of the harvest.

(Example) An embodiment of the present invention will be described based on the drawings.

The soil scraping plate 1 of the present invention is installed directly below the sorting roller B in the stationary selection device A and the sorting device A installed in a potato harvester or onion harvester, and scrapes the soil attached to the disk portion 3b of the rotary disk 3. It is something to be dropped.

Sorting roller B is for sorting crops such as potatoes and onions into small, medium, and large balls, and is made of rubber and has a disk part 3b integrally formed on one side of a boss part 3a with a square hole. A sorting device A is formed by arranging a plurality of rotary disks 3 on a shaft 4 in a skewered manner across machine frames M that face each other in parallel at a predetermined interval. .

Further, an appropriate number of disc-shaped spacers 5 having the same diameter as the outer diameter of the boss portion 3a are inserted between the rotary discs 3 attached to the shaft 4, depending on the size of the space to be set. .

Therefore, the space set according to the size to be sorted is the boss portion 3a of the rotary disk 3 on the front, rear, left and right sides.
and a disk portion 3b.

Further, a shaft 4 equipped with a rotary disk 3 constituting the sorting roller B is suspended horizontally across the inside of the machine frame M, and a sprocket gear 6 for rotation transmission is installed at one end of the shaft 4, respectively.
are fixed to each other and rotated by a motor (not shown) mounted on the machine frame M.

The earth and sand scraping plate 1 is a strip plate having an appropriate width and approximately the same length as the sorting roller B, and has a notch at one end in the long side direction of the strip deep enough to allow the disk portion 3b to enter the vicinity of the boss portion 3a. The recess 1a is formed in a comb-tooth shape, and a comb-teeth-shaped notch 1b having the same depth as the recess 1a and a different pitch from the recess 1a is formed at the other end. Attach the shafts 2a and 2b.

Therefore, two types of soil scraping plates 1 having different pitches are formed on one strip, and it is possible to immediately respond to changes in the distance between the rotary discs in the sorting roller B.

In addition, although the sorting standards for small and medium size balls on sorting roller B have been established, the size of potatoes and onions varies greatly depending on the year's crop, so the rotation on sorting roller B must be within the range of the sorting standards. The distance between the boards 3 must be varied.

Therefore, for example, if a plurality of soil scraping plates 1 each having comb-like notched recesses 1a and 1b with different pitches are prepared for small beads and for medium beads, it is possible to use the sorting roller B in multiple stages within the range of the sorting standard. It is possible to respond to changes in the distance between the rotary disks.

The mounting shafts 2a and 2b are formed by providing a round shaft 2a at the center of one end in the short side direction and a square shaft 2b at the center of the other end.

Incidentally, the mounting shafts 2a and 2b may be one piece.

In addition, the method of attaching the earth and sand scraping plate 1 is to place the earth and sand scraping plate 1 horizontally on the sorting roller B, and then insert the attachment hole 7 provided right below the machine frame M coaxial with the shaft b ₁ of the sorting roller B. Insert the round shaft 2a into the machine frame M on the opposite side of the mounting hole 7.
The square shaft 2b is inserted into the rotation hole 8a of the keyhole-shaped attachment hole 8, which is made up of a rotation hole 8a and a long hole 8b.

In this case, since the rotation hole 8a is located below the attachment hole 7, the earth and sand scraping plate 1 is in a state of being inclined toward the keyhole-shaped attachment hole side 8, and in this state, the earth and sand scraping plate 1 is reversed. The disc portion 3b of the rotary disk 3 in the sorting roller B and the notch recess 1 in the earth and sand scraping plate 1 are aligned perpendicularly to the sorting roller B.
a and 1b, the square shaft 2b in the rotation hole 8a is pushed up to the upper end of the elongated hole 8b by a thumbscrew 9 provided at the bottom of the mounting hole 8 and fixed.

Therefore, it can be easily installed in the machine frame M, and dirt adhering to the disk portion 3b can be scraped off during sorting of the harvest.

(Effects of the invention) Since the present invention has the above structure, one scraping board can be used as two types of scraping boards with different pitches, and by preparing several boards, it can be used for small balls and medium balls. It is possible to be equipped with a sand scraping plate that can immediately respond to any change in the spacing between the rotary discs in the sorting rollers used.
