Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a novel device for cutting off the roots and stems of Japanese pickled vegetables before shipping them after harvesting.

[Conventional technology]

In Rakkyo production areas, all the work of cutting off the stems and roots (hereinafter referred to as root cutting) is done by hand, and during the peak season, dozens of tons of rakkyo are shipped every day, mobilizing many people.

[Problem that the invention seeks to solve]

Manually cutting the roots of rakkyo requires long hours of work in the same position, resulting in stiff shoulders and lower back pain, and the work is inefficient.

This invention is an attempt to solve the above-mentioned problems, and its purpose is to use mechanical power to cut the roots of rakkyo in the correct position according to the size of the rakkyo, instead of manually cutting the roots of rakkyo. We are here to provide you with the equipment you need.

[Means for solving problems]

In order to solve the above problems, the present invention includes a rakkyo feeding hopper, a rakkyo root cutting mechanism for cutting off the roots and stems of the rakkyo, and a root cutting mechanism for arranging the rakkyo in the hopper one by one in series. The root cutting mechanism is fixed to a drive shaft parallel to the trough below the trough, and includes a rakkyo receiving wheel directly below the tip discharge port of the trough, and a root cutting blade support member facing above the wheel.・The circumferential surface of the wheel has a plurality of equally spaced receiving recesses into which the rakkyo fits horizontally, and the tip of the root cutting blade enters both sides of the widthwise center of the circumferential surface. The root-cutting blade support member includes a rakkyo holding member that extends along the upper circumferential surface of the wheel and in the rotational direction of the wheel, and blade plates on both sides of the member, and the double-edged plates are the size of a rakkyō. The trough has a discharge port with an opening/closing lid at the bottom of the tip, and a stepped part with a lower sloped side is provided in the middle of the trough. A short trough for adjusting the flow rate is pivotally supported on the tip side thereof so as to be able to freely swing upward, and when one of the recesses of the wheel is positioned upwardly, the opening/closing lid of the trough tip discharge port opens, and the opening/closing lid opens. When the short trough is closed, a cam mechanism that swings upward is used to open and close the lid, and a root cutting device is interposed between the short trough and the short trough.

[Effect]

The radish thrown into the hopper is fed into the trough one by one in a serial orientation, and is received horizontally in one of the plurality of rakkyo receiving recesses formed on the circumferential surface of the rakkyo receiving wheel in the root cutting mechanism. At the same time, when one of the recesses is located on the underside of the trough tip, the opening/closing lid of the downward discharge port at the trough tip is opened by a cam mechanism and is received in the recess of the wheel, and the opening/closing lid of the short trough in the middle of the trough is closed. At this time, the rakkyo is swung upward by the cam mechanism to stop the outflow to the tip side and throw out the overlapping rakkyo to the side.

Once received by the wheel, the pickled vegetables are held down by a root cutting blade support member that runs along the circumference on the upper side of the wheel, and the distance between the blade plates on both sides is adjusted depending on the size of the support member to cut the stems and roots of the pickled vegetables correctly. Cut at position.

The root cutting mechanisms 15a, 15b, and 15C for the Japanese rakkyo are shown in detail only at the trough 14C of the small Japanese rakkyo 13c. That is, a rakkyo receiving wheel 17 fixed to a drive shaft 16 parallel to the trough under the trough, and a wheel 17
It consists of a root cutting blade support member 18 facing above, and a wheel 1
On the circumferential surface of 7, there are four receiving parts 19 into which four rakkyō 13 are fitted horizontally at equal intervals, as shown in FIGS. 3 and 4.
As shown in FIG.
A groove 21 of a required width is provided into which the tip side of the blade plate 20 enters.

When one recess 19 of the wheel 17 approaches the lower surface of the tip of the trough 14c directly below the outlet 22, the opening/closing 123 that closes the outlet 22 opens. As shown in FIG. 7, the opening/closing lid 23 is provided with a recess a in a portion located directly above the wheel 17 into which one pickled radish falls.

The opening/closing lid 23 is opened by a cam plate 24a fixed to the drive shaft 16 of the wheel 17, as shown in FIG. 1, FIG. 3, and FIGS. 7 and 8, and as shown in FIG. The plate also has four recesses 25a formed at equal intervals around its periphery, and an arm 26a with one end attached to the opening/closing lid 23 is inserted into the recesses.

When the small wheel 27a approaches directly below the cam plate 24a,
The lid is opened by fitting into two recesses 25a.

As shown in FIGS. 3 to 5 and 6, the root cutting blade support member 18 is attached to a support 28 supported by the machine frame 1.
As shown in FIGS. 6 to 6, at the lower end of the plate part 29 attached to the support column 28, one end of a rakkyo holding member 30 which is long in the circumferential direction and follows the circumferential surface of the wheel 17 is attached to the lower end of the plate part 29 that is attached to the support column 28. A pair of arms 32 for supporting the blade plate 20 are supported by a shaft 33 on both left and right sides of the plate portion 2S so as to be able to swing left and right, and a midway portion in the length direction thereof is supported by a shaft 31. has a convex portion 34 on the surface facing the opposing arm, and an inclined surface 35 into which the lower side enters is formed on the opposite surface of both the convex portions, so that the wheel 17 fits into the concave portion of the wheel 17 and is pressed by the presser member 30. Depending on the diameter of the rakkyo 13, the opposing protrusions 34 move apart or approach each other to move the blade plate 20 to the correct position for cutting the stem and root of the rakkyo. 36 This is a guide supported on the machine frame 1 on the forward side of the bar holding member 30.

In FIGS. 1 and 2, 37a, 37b, and 37C are short streams whose rear end is supported by a shaft 39 at a setup part 38 formed in the middle of the troughs 14a, 14b, and 14c and whose sloped lower side is lower. This is an N adjustment trough, and the rakkyo from the hopper 2 is configured so that it first reaches this flow rate adjustment trough and then flows out.

In other words, only one rakkyo is always waiting at the tips of the troughs 14a, 14b, and 14c, so that until the rakkyo is discharged from the tips of the troughs, the next rakkyo will flow 1 ftl! Adjustment trough 3? a, 37b, 3? One rakkyo is waiting at the tip of C and held in a horizontal position, and in this state, even if the following rakkyo 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 horizontal positions is a second cam plate 24 on the drive shaft 16 of the wheel 17, as shown in FIG. 1 and FIG.
b is fixed, and a recess 25b similar to the recess 25a of the first cam plate 24a is formed on the circumferential surface of this cam plate, and an arm 26b whose one end is fixed to the flow rate adjustment trough 37c is inserted into this recess. The position of the recess 25b is such that the small wheel 27b at the other end fits into the recess 25b, and the position of the recess 25b is such that the small wheel 27a fits into the recess 25a of the first cam plate 24a and the opening/closing lid 23 at the tip of the trough 14a is opened. Recessed portion 25b of second cam plate 24b
The small wheel 27b detached from the flow adjustment trough 3, which had a downward slope. c changes to horizontal position and flow ft adjustment trough 3? Rakkyo outflow from c will stop.

Next, I will explain the operation of this rakkyo root cutting device.
The rakkyo put into the hopper 1 rides on the endless belt 3 at the bottom of the hopper and is discharged onto the rough surface 10a, where soil and sand are sieved off by the vibration of the vibrator 11, and the sieves 10b and IOC 110d below are passed through the sieve 10b and IOC 110d. , small rakkyo 13a, 13b, and 13C are sieved and fed into the respective troughs 14a, 14b, and 14C in a vertical line by the vibration of the linear feeder 41, and are fed to the discharge port 22 on the lower surface of the tip of the trough.
The rakkyo root cutting mechanism 158.15b, 15C is fitted laterally into one recess 19 on the circumferential surface of the rakkyo receiving wheel 17, and then by rotation of the wheel 17, the rakkyo is cut into a root cutting blade support member. The rakkyo is pressed by the rakkyo holding member 30 of 18, and the rakkyo passes through the gap formed by the inclined surface 35, which has a pair of left and right root cutting blade support members 18 facing each other, and into which the lower sides of the mutually opposing surfaces of the convex portions 34 on the opposing surfaces enter. At this time, the gap' is forcibly expanded or contracted depending on the size of the rakkyo, and the distance between the left and right blade plates 20 changes. The cut is made in the proper position and is received by the receiving seat 42.

Moreover, the rakkyo to be supplied to the rakkyo receiving wheel 17 is carried out by fitting the tip wheel 27a of the arm 26a from the opening/closing M2T into one recess 25a of the first cam plate 24a fixed to the same drive shaft 16 as the wheel 17. When this happens, the opening/closing lid 23 is opened and the coil spring 4 is released.
3, and the troughs 14a, 14b, 1
There is a short trough 3 for flow rate adjustment in the middle step of 4C. a
, 3? b.3? C is the second cam plate coaxial with the first cam plate 24a.
By the rotation of the cam plate 24b, when the opening/closing lever 23 is closed, it changes to a horizontal position and stops the flow of the rakkyo toward the discharge port 22, so that the root cutting of the rakkyo can be smoothly performed at the wheel part.

As can be seen in Figs. 4 and 7, the cross-sectional shape of the circumferential surface of the radish receiving wheel 17 is a trough-like shape where the central part in the width direction becomes deeper. Therefore, when the rakkyo is discharged from the discharge port 22 of the trough, even if one recess 1S of the trough is in a position approaching directly below the discharge port 22, the discharged rakkyo will not reach the circumferential surface of the wheel. is transferred and fitted into the recess.

〔effect〕

By using the root cutting device of this invention,
It has the following effects.

(1) From a rakkyo input hopper, a rakkyo root cutting mechanism that cuts out the roots and stems of the rakkyo, and a trough that supplies the rakkyo in the hopper one by one in a serial orientation to the root cutting mechanism. The root cutting mechanism consists of a rakkyo receiving wheel directly below the tip discharge port of the trough, which is fixed to the drive shaft parallel to the trough below the trough, and a root cutting blade support member facing above the wheel. The circumferential surface is provided with a plurality of equally spaced receiving recesses into which the rakkyo fits horizontally, and grooves are provided on both sides of the widthwise center of the circumferential surface into which the tip of the root cutting blade enters. The supporting member consists of a rakkyo holding member that extends along the upper circumferential surface of the wheel and in the rotational direction of the wheel, and blade plates on both sides of the member, and the double blade plates extend in the left-right direction in accordance with the size of the rakkyō. Since the sliding pieces that approach and leave each other are supported, once the radish is put into the hopper, it is supplied to the trough in a single line vertically, and from the discharge port at the tip of the trough to one of the circumferential surfaces of the rakkyo receiving wheel in the root cutting mechanism. The rakkyo is fitted horizontally into the recess, and then as the wheel rotates, the rakkyo is held down by the holding member, and the left and right pair of root cutting blade support members are moved closer and closer to each other in accordance with the diameter of the rakkyo, and the blade part You can cut the stems and roots of rakkyo at the correct cutting position.

(2) The discharge port at the bottom of the tip of the trough that supplies rakkyo to the rakkyo 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, and this step is used for adjusting the flow 1i. A long trough is swingably supported with its tip end on the upper piece, and when one recess of the wheel is positioned upward, the opening/closing lid of the trough tip opening opens, and when the opening/closing lid is closed, the short trough The flow rate adjustment trough has a cam mechanism that swings upward, which also serves as the opening/closing lid, and is interposed in the 1m flow regulating trough, so when one recess of the rakkyo receiving wheel approaches just below the outlet of the trough, the opening/closing lid opens. One rakkyo is released, and at this time, the tip side of the flow rate regulating trough rises to a horizontal position, and the release of the rakkyo that rides on this trough stops and the following rakkyo are thrown out to the side, so the rakkyo root cutting mechanism is activated. You can cut the stems and roots of the rakkyo without getting too crowded.
