At the bottom of the body 1, a substantially semi-cylindrical water tank frame 15 with both ends closed is arranged to form a water tank, and this frame 15 can be rotated vertically by a hinge part 16 on one side. The other side is supported by a stopper 17 in a detachable manner.

A lower roll brush 18 for rough washing is disposed above the water tank frame 15 so that a part thereof is submerged in the water tank formed by the water tank frame 15, and this roll brush 18 is suspended horizontally on the body 1. It is adapted to be rotated by a rotating shaft 19. Further, the lower roll brush 18 is shifted toward the front side of the upper roll brush 2 and arranged parallel thereto.

Below the lower roll brush 18, a lower guide 20 formed in a substantially semi-cylindrical shape is disposed concentrically upward so as to form a passage 21 between the guide 20 and the lower roll brush 18. Similar to the upper guide 4 described above, this lower guide 20 also has a plurality of arc-shaped divided pieces 22 connected to each other by a hinge 23 so as to be openable and closable. is suspended. However, since the aquarium frame 15 moves in the vertical direction, the lower guide 20
a compression spring 26 positioned with one end secured to the
is suspended in a state in which it is in elastic contact with the upper surface of the aquarium frame 15.

The upper passage 5 and the lower passage 21 cooperate to form a series of approximately S-shaped passages, and a supply chute 27 is provided on the front wall of the fuselage 1 facing the upward end of this S-shaped passage. However, discharge chutes 28 are provided on the rear wall of the body 1 facing the downward end.

A motor 29 as a roll brush drive source is installed on the ceiling wall of the aircraft 1.
The rotational force is transmitted to the rotating shafts 3, 19 of both roll brushes 2, 18 by the chain sprocket transmission mechanism 30.
Both roll brushes 2 and 18 are transmitted to rotate in opposite directions and synchronously with each other, as shown by solid arrows in FIG. The motor 29 and the transmission mechanism 30 are surrounded by a cover 31 attached to the fuselage 1.

An upper impeller 32 is installed on one side of the upper roll brush 2.
is provided so that its boss portion 33 is fixedly fitted to the rotating shaft 3 and rotates together with the roll brush 2, and this impeller 32 has a plurality of blades 34 (eight in the illustrated example). They are provided on the outer periphery of the boss portion 33 in a substantially equiangular radial manner. Further, a lower impeller 35 is provided on one side of the lower roll brush 38 so that the boss part 36 is fitted onto the rotating shaft 19 and rotates together with the roll brush 18, and a plurality of blades 37 are provided on the boss part 36. They are protruded approximately equiangularly on the outer periphery. Both impellers 32 and 35 are both roll brushes 2 and 1.
By rotating integrally with 8, the passages 5, 21
The leaf feeding means substantially constitutes a leaf feeding means that follows the movement of the root vegetable while holding the leaf portion of the root vegetable being moved.

Next, the usage method and operation of the root vegetable washer having the above structure will be explained.

First, the hook part of the free end is hooked on the stopper 17 to put the aquarium frame 15 in a bridged state, and the water supply pipe 11,
Preliminary water is discharged from a nozzle 14 through a communication pipe 12 and a branch pipe 13, and water is stored in the tank frame 15 up to the vicinity of a rotating shaft 19. Subsequently, when the motor 29 is operated, its rotation is transmitted to the chain sprocket transmission mechanism 3.
0 to the rotating shafts 3 and 19, respectively,
The upper roll brush 2 and the upper impeller 32 and the lower roll brush 18 and the lower impeller 35 are the second
As shown by solid line arrows in FIGS. 3 and 3, they are synchronously rotated in opposite directions.

In this state, a root vegetable, for example, a radish 38 having a leaf part 39 of an appropriate length, is laid down on the supply chute 30 and rolled, and the root part 40 is thrown into the upwardly opened inlet side end of the lower passage 21. Passage 21
The radish 38 thrown into the passage 21 moves along the roll brush 18 in the passage 21 due to the contact resistance of the guide 20 and the driving action of the lower roll brush 18 that slides into contact with the guide 20 while rotating.
It is sent while being rolled in the direction of rotation. When the root part 40 of the radish passes through, the interval between the passages 21 is determined by the thickness of the root part 40 of the radish, as each divided piece 22 rotates on the hinge 23 and is moved back and forth in the inner and outer directions by the expansion and contraction of the compression spring 26. Automatically adjusts to wide/narrow according to the width.

Moreover, at the same time that the root part is thrown into the passage 21, the leaf part 39 of the radish 38 is accommodated inside between the adjacent blades 36, 36 of the plate impeller 35. Since the impeller 35 rotates synchronously with the lower roll brush 18, the leaf portion 39
The root part 4 of the radish 38 remains in the state between the wings.
0 in the passage 21.

While the daikon radish 38 being transported in such a state moves through the water stored in the water tank frame 15, the lower roll brush 18 scrapes off mud adhering to the outer circumferential surface of the root portion 40 of the radish 38. The scraped mud is dispersed in the water, and the mud adhering to the roll brush 18 is washed off in the water.

During this cleaning, the leaf part 39 of the radish is cleaned with the roll brush 1.
Since the leaf parts of adjacent daikon radish are surrounded by an impeller 35 that rotates in synchronization with the roller brush 8, the leaf parts of adjacent radish do not hit each other or rub against each other during conveyance. Since the leaf portion 39 is prevented from being drawn deep into the
is prevented from being damaged by the roll brush 18.

The radish 38 is transported to the lower passage 2 while being washed.
When it reaches the outlet side end of 1, it is delivered to the inlet side end of the upper passage 5 which opens downward so as to be opposite to this. Radish 3 received in upper passage 5
The root portion 40 of the roller 8 is rolled and sent through the passage 5 in the direction of rotation of the roll brush 2 by the cooperation of the upper guide 4 and the upper roll brush 2. At this time, the direction of rotation of the radish 38 in the upper passage 5 is opposite to that in the lower passage 21. During this transportation, the distance between the passages 5 is automatically adjusted to be wide or narrow by the dividing pieces 6, hinges 7, compression springs 10, etc., as described above. Moreover, at the same time as being delivered to the passage 5, the leaf part 39 of the radish 38 is housed inside between the adjacent blades 34, 34 of the upper impeller 32 which rotates in synchronization with the lower impeller 35. Since this lower impeller 32 rotates integrally with the upper roll brush 2, the leaf portion 39 is conveyed following the movement of the root portion 40 in the passage 5 while remaining housed between the blades.

The radish 38 transported in such a state is washed with water poured into the passage 5 from the nozzle 14 while the outer circumferential surface of the root portion 40 is rubbed by the upper roll brush 2, and is finished washed. Even during this cleaning, the leaf portions 39 of the radish 38 are surrounded and protected by the upper impeller 32, so no damage occurs. Further, the motor 27 is connected to the nozzle 14
Since it is installed above the roof, it will not be exposed to water.

The radish 38 is conveyed while being finished washed, and when it reaches the exit side end of the upper passage 5, it falls onto the discharge chute 28 arranged to face this, and rolls down this.

After the cleaning operation, the aquarium frame 15 is moved to the stopper 1 at the free end.
7, the hinge portion 16 is rotated downwardly and opened as shown by the imaginary line in FIG. As a result, all the muddy water in the tank frame 15 is reliably discharged at once and along the arc surface.

According to this embodiment, since the impeller is provided on one side of the roll brush so as to rotate together, the leaves can be surrounded and protected by the blades of the impeller during cleaning, thereby preventing damage to the leaves. This can be prevented and a decrease in freshness can be avoided. Furthermore, since the impeller only needs to be fitted coaxially to the shaft of the roll brush, the structure, assembly work, etc. are extremely simple.

Since the water tank frame is configured to be opened and closed by attaching and detaching the stopper, the water can be drained all at once with a single touch operation, resulting in extremely good workability. Moreover, since the tank frame is semi-cylindrical, drainage is quickly and reliably carried out along the slope.

Since the motor is disposed in the upper position, it is not exposed to water and is extremely safe, and economical effects can be obtained by omitting a waterproof structure and improving durability.

In addition, after rough washing is carried out by storing water in the lower roll brush and water tank frame, finish washing is carried out by pouring water into the upper roll brush and nozzle. It is economical because water used in the final washing can be reused in the rough washing.

Since the path of the object to be cleaned is formed in an S-shape, the direction of rotation of the object to be cleaned during transportation is opposite to each other in the lower passage and the upper path. It can be cleaned evenly and the entire surface can be cleaned reliably.

The guide facing the roll brush is bent in the middle and has an independent suspension structure, so the gap between the passages is automatically adjusted to widen or narrow according to the thickness of the object to be cleaned, reducing the difference in cleaning quality depending on the thickness of the object to be cleaned. Occurrence can be prevented.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and may be modified without departing from the gist thereof.
It goes without saying that various changes are possible.

For example, as a means for feeding the leaf portion in synchronization with the roll brush, a belt or the like having partitions corresponding to wings may be used.

The aquarium frame may be configured to open and close in a double-doored manner, or may be a hollow body with a trapezoidal cross section with an open upper surface.

When a plurality of grooves are arranged parallel to the axis on the inner surface of the cushion member of the guide, the object to be cleaned rolls in a zigzag pattern while finely moving up and down in the passage, causing bends and parts with different diameters. Even root vegetables (for example, lotus root, etc.) that have the following properties can be cleaned evenly and reliably over the entire surface.

Further, even if a brush is used as a guide, the same functions and effects as in the above embodiment can be obtained.

Although the above embodiment describes the case of cleaning daikon radish with leaves, the cleaning machine according to the above configuration is also effective for cleaning carrots, burdock, lotus root, etc., and of course can also be used for cleaning radish without leaves. can.

In this case, it is desirable to adjust the length of the rods 8, 24 by operating the stoppers 9, 25 made of double nuts or the like so that the gap between the passages 5, 21 corresponds to the thickness of the root vegetables to be cleaned. .

As explained above, according to the present invention, root vegetables with leaves can be washed without damaging the leaf portions.
