A sieve sorting sieve 10c consisting of parallel stripes that only catches lint particles and drops the rest, and a sieve sieve 10d that only catches lint particles and drops debris are integrated into the hopper 2 in that order. The hopper 2 and each screening sieve are vibrated by a vibrator 11.

12 is a waste receiving chute below the sorting sieve 10d.

On the front side of each of the large, medium and small sorting sieves 10b, 10c and 10d, there is a trough 14a for the large size 13a, a trough 14b for the medium size 13b, and a small size 13c.
A trough 14c is connected to each trough, and each trough has a root cutting mechanism 15a, 15 with a wobble at the bottom of the tip.
There are b and 15c.

Root cutting mechanisms 15a, 15b, 15 for rattling
Figure c shows only the trough 14c portion of the small 13c of the rattling pattern in detail. That is, it consists of a wobbling support wheel 17 fixed to a drive shaft 16 parallel to the trough below the trough, and a root cutting blade support member 18 facing above the wheel 17. As shown in FIG.
As shown in FIG. 4, grooves 21 of a required width are formed on both sides of the widthwise central portion of the circumferential surface of the wheel 17, into which the tip side of the blade plate 20 of the root cutting blade support member 18 enters. Prepared.

One recess 19 of the wheel 17 is a trough 14c
When approaching the lower surface of the tip of the discharge port 22 directly below the discharge port 22, the opening/closing lid 23 that closes the discharge port 22 opens. As shown in FIG. 7, the opening/closing lid 23 is formed with a recess a in a portion located directly above the wheel 17, into which a single piece of lumber falls.

A pair of arms 32 supporting the blade plate 20 are supported by a shaft 33 on both left and right sides of the plate portion 29 so as to be able to swing from side to side. Convex portion 3 on the surface facing the opponent arm
4, and an inclined surface 35 into which the lower side enters is formed on the opposing surface of both convex portions. , the opposing protrusions 34 separate or approach each other to move the blade plate 20 to the correct cutting position for the stem and roots of the stump. 36 is a guide supported on the machine frame 1 on the forward side of the wobbling presser member 30.

37a, 37b, 37 in Figures 1 and 2
Reference character c is a short flow rate adjustment trough whose rear end is supported by a shaft 39 in a setup part 38 formed in the middle of the troughs 14a, 14b, 14c where the sloped lower side is lowered, and is designed to prevent slipping from the hopper 2. is arranged so that it flows out after entering this flow rate adjustment trough at one end.

In other words, only one rattle is always waiting at the tips of the troughs 14a, 14b, and 14c, so that until the rattle is discharged from the tips of the troughs, the next rattle is sent to the flow rate adjustment trough 3.
One is waiting at the tip of 7a, 37b, 37c and is in a horizontal position, and in this state, even if the following wobble flows into the flow rate adjustment trough, it rides on the over-receiving plates 40 on both sides and is thrown out to the side. .

The mechanism for changing the flow rate adjustment troughs 37a, 37b, and 37c to the horizontal position is the drive shaft 1 of the wheel 17, as shown in FIG. 1 and FIG.
A second cam plate 24b is fixed to 6, and a recess 25a of the first cam plate 24a is formed on the circumferential surface of this cam plate.
The arm 2 has a recess 25b similar to the one shown in FIG.
The small wheel 27b at the other end of the recess 25b is fitted into the recess 25b, and the position of the recess 25b is the same as that of the first cam plate 24a.
The small wheel 27a fits into the recess 25a of the trough 14.
When the opening/closing lid 23 at the tip of a is opened, the small wheel 27b is removed from the recess 25b of the second cam plate 24b.
The flow rate adjustment trough 37c, which had been sloped downward, changes to a horizontal position, and the sluggish outflow from the flow rate adjustment trough 37c is stopped.

Next, to explain the operation of this device for cutting the roots of loose grains, once the grains are fed into the hopper 1, they ride on the endless belt 3 at the bottom of the hopper and pass through the rough sieve 10a.
The soil and sand are sieved out by vibration by the vibrator 11 and passed through the sieves 10b and 10 below.
Large, medium, small wobble by c, 10d 13
a, 13b, 13c and straight feeder 4 is sieved into each trough 14a, 14b, 14c.
The root cutting mechanism 15a, which is supplied vertically in one line with the vibration of
Fitted laterally into one recess 19 on the circumferential surface of the wobble receiving wheel 17 in 15b, 15c,
Next, as the wheel 17 rotates, the wobble is suppressed by the wobble pressing member 30 of the root cutting blade support member 18, and the root cutting blade support member 18 has a pair of left and right opposing sides, and a convex portion 34 on the opposing surface. When the rattle passes through the gap formed by the inclined surface 35 into which the lower sides of the mutually opposing surfaces enter, the gap is forcibly expanded or contracted depending on the size of the rattle, and the distance between the left and right blade plates 20 is reduced. If the stems and roots change and are received in the recesses of the wheel, the stems and roots are cut in the proper position and received in the receiving chute 42.

In addition, the wobble that is supplied to the wobble receiving wheel 17 is connected to the same drive shaft 16 as the wheel 17.
One recess 2 of the first cam plate 24a fixed to
When the small end wheel 27a of the arm 26a from the opening/closing lid 27 is fitted into the opening/closing lid 27, the opening/closing lid 23 is opened and released, and after being released, it is closed with the help of the coil spring 43, and the troughs 14a, 14b, 14c are closed. A short trough 37 for flow rate adjustment is provided at the middle step.
a, 37b, and 37c change to a horizontal position and wobble toward the discharge port 22 when the opening/closing lid 23 is closed due to the rotation of the second cam plate 24b coaxial with the first cam plate 24a. Since the flow of water is stopped, root cutting is carried out smoothly even if there is no wobbling at the wheel part.

As can be seen in FIGS. 4 and 7, the cross-sectional shape of the circumferential surface of the damping catcher wheel 17 has a trough shape with a deeper center in the width direction. It lies stably in the trough, so that when the loose particles are discharged from the outlet 22 of the trough, one recess 1 of the trough
Even if the discharge port 9 is located at a position directly below the discharge port 22, the discharged material rolls on the circumferential surface of the wheel and fits into the recess.

(1) A hopper for feeding radish, a root cutting mechanism for cutting the roots and stems of radish, and a root cutting mechanism for oriented radish in the hopper one by one in series. The root cutting mechanism is fixed to a drive shaft parallel to the trough under the trough, and includes a wobble receiving wheel directly below the distal end outlet of the trough, and a root cutting blade support member facing above the wheel. The circumferential surface of the wheel is provided with a plurality of receiving recesses that are spaced at equal intervals and into which the ratchets are fitted horizontally, and the tips of root cutting blades are provided on both sides of the widthwise center of the circumferential surface. The root cutting blade support member is provided with a groove into which the side is inserted, and the root cutting blade support member is composed of a wobbling retaining member extending along the upper circumferential surface of the wheel and extending in the rotational direction of the wheel, and blade plates on both sides of the member, and the double blade plate is Each piece is supported by a sliding piece that moves toward and away from the left and right depending on the size of the sludge, so when the sludge is fed into the hopper, it is fed into the trough in a single line vertically, and the roots are discharged from the outlet at the tip of the trough. It is fitted horizontally into one recess in the circumferential surface of the wobble-receiving wheel in the cutting mechanism, and then as the wheel rotates, the wobble is held down by a holding member, and a pair of left and right root cutting blade support members are pressed against the wobble. It is possible to cut the stems and roots of the snail at the correct cutting position with the blade part, which approaches and separates according to the diameter of the snail.

(2) The outlet at the bottom of the tip of the trough that supplies the rattle to the rattle receiving wheel is opened and closed with an opening/closing lid, and there is a step in the middle of the trough where the lower side of the slope is lower. When a short adjustment trough is slidably supported with its tip side on the upper piece and one of the recesses of the wheel is positioned upward, the opening/closing lid of the trough tip opening is open, and when the opening/closing lid is closed. The short flow rate adjustment trough has an upwardly swinging cam mechanism interposed between the opening/closing lid and the flow rate adjusting trough, so that when one recess of the rattling receiving wheel approaches just below the outlet of the trough, the opening/closing lid closes. opens and discharges one rattle. At this time, the tip side of the flow rate regulating trough rises to a horizontal position. When it rides on this trough, the discharge of the rattle is stopped and the subsequent rattle is forced to the side. Since the root cutting mechanism section of the radish can reliably cut the stems and roots of the ramid, the root cutting mechanism does not become crowded.
