Description

  The present invention relates to a washing machine for root vegetables such as radish, carrot and beef bowl.

Rotate root vegetables such as radish between the roll brush (lower brush) and presser brush (upper brush) to remove dirt and mud adhering to the radish (wash out), and finally shower on the radish. There has been proposed a root vegetable washing machine that sprays fresh water in the form of water to perform final rinsing (see, for example, Patent Document 1).
FIG. 4 shows a root vegetable washing machine (hereinafter simply referred to as a washing machine) using a conventional roll brush and presser brush.
4A is a plan view, FIG. 4B is a cross-sectional view of the X1 portion of FIG. 4A in the arrow direction, and FIG. 4C is the arrow direction of the X2 portion of FIG. 4A. FIG. FIG. 4D is a perspective view of the roll brush and the presser brush. In the figure, only the main parts such as the brush of the cleaning machine are shown, and the side members, the installation legs, the driving device, etc. are omitted.

The washing machine includes a supply unit 11 that supplies radish 41, a preliminary washing unit 12, a finish washing unit (shower washing unit) 13, and a water tank 14.
The supply unit 11 includes a supply table 111 on which the radish 41 is placed, and supplies the radish 41 from the supply table 111 to the preliminary cleaning unit 12.
The preliminary cleaning unit 12 includes a plurality of roll brushes (lower brushes) 21 and a plurality of presser brushes (upper brushes) 22, and both brushes are arranged to face each other. The roll brush 21 includes a rotating shaft 213, a hair implanting member 211 attached to the rotating shaft, and hair 212 implanted in the hair implanting member 211. The presser brush 22 includes a plate-like hair implanting member 221 and hair 222 implanted in the hair implanting member 221, and the hair implanting member 221 is attached to the upper surface member 121. The roll brush 21 and the presser brush 22 are arranged such that the tips of the bristles 212 and 222 of both brushes are in contact with each other or are separated to about 10 mm. The distance between the roll brush 21 and the presser brush 22 is set in advance to a predetermined size in consideration of the thickness of the radish to be cleaned.
The rotating shaft 213 of the roll brush 21 is rotated by a chain (not shown) that drives a sprocket (not shown) attached to the rotating shaft by a motor or the like. The chain simultaneously rotates the plurality of roll brushes 21 in the same direction.

The finish cleaning unit 13 includes a drainboard-like discharge table 132 for arranging the pre-cleaned radishes 41 side by side, and a shower water supply pipe 31 attached to the upper surface member 131. The shower water supply pipe 31 has a large number of pores for spraying water to the discharge table 132.
The radishes 41 arranged on the discharge table 132 are rinsed with clean water such as tap water supplied in a shower form from the shower water supply pipe 31 and are finished and washed. The washed radish is stored in a storage case, a cart (not shown) or the like.
The water tank 14 is disposed below the supply unit 11, the preliminary cleaning unit 12, and the finish cleaning unit 13, and includes a drain pipe 142. The water level of the water 141 in the water tank 14 is set to such an extent that the tip of the bristles 212 of the roll brush 21 is immersed. When the water 141 becomes equal to or higher than the set water level, the water 141 is discharged from the water tank 14. The water level is set by, for example, providing an overflow port in the upper part of the water tank 14 or making the height of the upper discharge port of the drain pipe 142 the same as the set water surface.

  The radish 41 is supplied from the supply unit 11 so as to be parallel to the rotation shaft 213 of the roll brush 21. The supplied radish 41 advances toward the finish cleaning unit 13 while rotating between the roll brush 21 and the presser brush 22 of the preliminary cleaning unit 12, and the soil and mud adhering to the surface of the radish 41 in the meantime, Washed off. The radish 41 that has advanced to the finish cleaning unit 13 is finish cleaned with fresh water supplied from the shower water supply pipe 31.

Next, the movement of the radish in the washing machine of FIG. 4 will be described with reference to FIG.
First, FIGS. 5A1 and 5A2 will be described. 5A1 shows a state when the radish 41 advances from the X3 direction to the P2 direction, and FIG. 5A2 shows a partial cross-sectional view in the X3 direction of FIG. 5A1.
The radish 41 is placed on the upper end of the bristles 212 of the roll brush 21, and when the roll brush 21 rotates in the arrow P1 direction (counterclockwise in FIG. 5 (a1)), the radish 41 is clockwise. Try to rotate to. However, the radish 41 is pushed in the direction of the arrow P2 by the frictional force (resistance force) of the bristles 222 of the presser brush 22, and pushes and bends the bristles 222 to advance in the direction of the arrow P2.
The radish 41 that has passed through the preliminary cleaning unit 12 pushes and bends the hair 222 of the last roll brush 22 as shown in FIG. 5B, proceeds in the P2 direction, and is discharged (moved) to the finishing cleaning unit 13.

  In addition to the washer shown in FIG. 3, a washer that omits the presser brush 22 and injects pressurized water between adjacent roll brushes 21 in FIG. 3 to wash root vegetables such as radishes is proposed (Patent Document). 2).

Japanese Patent Laid-Open No. 10-210961 JP 2002-1553829 A

  In FIG. 5, the roll brush 21 and the presser brush 22 remove the soil and the like attached to the radish 41 with their hairs 212 and 222 contacting the surface of the radish 41, but the soil and the like of the tail portion 411 of the radish 41 is , May remain without being fully removed. Further, the soil or the like attached to the radish 41 may be difficult to remove due to the difference in the adhesion strength depending on the soil quality, the dry state, or the weather when harvested. In such a case, a method of coping with hardening the hairs 212 and 222 of the roll brush 21 and the presser brush 22 or increasing the number of the roll brush 21 and the presser brush 22 can be considered. If the number of both brushes is increased, the skin of the radish 41 will be peeled off, the luster will be lost, and the peeled portion of the skin will rot and the commercial value will be reduced.

Further, the soil that has not been removed by the preliminary washing unit 12 cannot be removed by spraying fresh water in a shower-like manner by the finish washing unit 13, and the radish 41 on the discharge table 132 does not rotate, so the back side of the shower water This part of the soil was particularly difficult to remove. For this reason, conventionally, it has been necessary to manually remove the remaining soil after the finish cleaning and clean it, and the burden of the operation has been large.
Further, as shown in FIG. 5B, the radish 41 passes through the preliminary cleaning unit 12 and proceeds in the P2 direction, and is discharged to the finishing cleaning unit 13. At that time, the speed is too high, and the radish 41 rushes through the discharge table 132 and is discharged. May not align on the stage 132. Therefore, the radish 41 on the discharge table 132 may not be sufficiently cleaned.

Moreover, since the washing machine using the pressurized water does not use a presser brush, it is difficult to completely remove the soil adhering to the radish etc., and the radish etc. on the roll brush is parallel to the traveling direction of the radish (roll The direction may be changed (turned) in a direction orthogonal to the rotation axis of the brush and may not move in a state of being aligned in parallel with the rotation axis of the roll brush.
In view of these problems, the present invention can remove soil attached to radishes and the like almost completely without peeling off the skin of radishes and the like, and the radishes and the like are parallel to the rotation axis of the roll brush. It is an object of the present invention to provide a root vegetable washing machine that can move in an aligned state.

In order to achieve the object of the present invention, the root vegetable cleaning machine according to claim 1 includes a preliminary cleaning unit, a pressurized water cleaning unit, and a finish cleaning unit, and the preliminary cleaning unit includes a plurality of roll brushes and rolls thereof. The pressurizing water washing part is provided with a pressurizing water supply means which arranges a roll brush and a hairless roll alternately, and injects pressure water into the roll brush and a hairless roll. .
The root vegetable cleaning machine according to claim 2 is the root vegetable cleaning machine according to claim 1, wherein the pressurized water cleaning section is a roll brush and a hairless roll so that the hairless roll is positioned on the finish cleaning section side. Is arranged.
The root vegetable cleaning machine according to claim 3 is the root vegetable cleaning machine according to claim 2, wherein the finishing cleaning section includes a water tank for storing finishing cleaning water. Machine.
The root vegetable cleaning machine according to claim 4 is the root vegetable cleaning machine according to claim 1, 2 or 3, wherein the pressurized water cleaning section relays each pair of a roll brush and a hairless roll. A presser brush is provided.

The washing machine of the present invention can wash radishes and the like without peeling the epidermis by combining the pre-cleaning unit and the pressurized water cleaning unit. By spraying the pressurized water, not only the thin tail such as radish, but also the soil remaining without being cleaned in the preliminary cleaning section can be removed almost completely.
Since the cleaning machine of the present invention forms a pressurized water cleaning unit with a roll brush and a hairless roll, the radish and the like are parallel to the rotation axis of the roll brush and the hairless roll without impairing the cleaning effect of the brush. Can move in an aligned state. Further, by disposing the hairless roll on the finish washing section side of the pressurized water washing section, it is possible to prevent the dirty water in the pressurized water washing section from scattering to the finishing washing section.

  Moreover, since the pressurized water washing | cleaning part of this invention is providing the relay presser brush (presser brush) for every pair of roll brush and a hairless roll, the radish etc. between the roll brush and the hairless roll in which a relay presser brush does not exist are Until it is extruded to the next radish or the like, it stays between the roll brush and the hairless roll, rotates, and is exposed to pressurized water. Therefore, by adjusting the supply interval of the radish supplied from the supply unit, the residence time can be adjusted, and the pressurized water washing of the radish can be performed efficiently.

When the radish or the like is cleaned by the cleaning machine of the present invention, the work time for rework cleaning after cleaning can be greatly shortened.
Since the cleaning machine of the present invention can drive all roll brushes of the pre-cleaning section and the roll brush and hairless roll of the pressurized water cleaning section at once by a power transmission means such as a common chain, the drive device for the roll brush and the hairless roll And the control of the roll brush and the hairless roll is simplified.

FIG. 1 shows a root vegetable washing machine according to Embodiment 1 of the present invention. FIG. 2 shows the configuration and operation of each part of the washer of FIG. FIG. 3 shows a root vegetable washing machine according to Embodiment 2 of the present invention. FIG. 4 shows a conventional root vegetable washing machine. FIG. 5 is a diagram for explaining the relationship between the brush and the radish of the washing machine of FIG.

  An embodiment of the present invention will be described with reference to FIGS.

A root vegetable washing machine (hereinafter simply referred to as a washing machine) according to Embodiment 1 of the present invention will be described with reference to FIGS.
FIG. 1 shows the overall configuration of the washing machine.
1 (a) is a plan view, FIG. 1 (b) is a cross-sectional view of the X1 portion of FIG. 1 (a) in the direction of the arrow, and FIG. 1 (c) is a pre-cleaning section and pressurized water in FIG. 1 (a). It is a figure explaining a washing | cleaning part.
The washing machine includes a supply unit 11 that supplies radish 41, a preliminary washing unit 12, a pressurized water washing unit 15, a finish washing unit 13, and a water tank 14.
Since the supply unit 11, the finish cleaning unit 13, and the water tank 14 are the same as those of the cleaning machine of FIG.

Next, the preliminary cleaning unit 12 will be described.
The basic structure of the preliminary cleaning unit 12 is the same as that of the cleaning machine of FIG. 4, and the roll brush 21a and the presser brush 22a are arranged to face each other. The structure of the roll brush 21a and the presser brush 22a is the same as that of the roll brush 21 and the presser brush 22 shown in FIG. 4, but the presser brush 22a is partially different in hardness from the presser brush 22 shown in FIG. Yes. That is, the presser brush 22a is composed of a low-speed presser brush 22a2 and another presser brush 22a1, and the bristles of the low-speed presser brush 22a2 are softer than the bristles of the presser brush 22a1. In the case of the same material, the brush becomes soft when the thickness is reduced.
The low-speed presser brush 22a2 is provided on the pressurized water washing unit 15 side, and has a function of reducing the release speed (movement speed) of the radish as will be described later.
The low-speed presser brush 22a2 may have the same configuration as the presser brush 22a1, but by slowing down the radish by the low-speed presser brush 22a2, the radish is gently moved from the preliminary cleaning unit 12 to the pressurized water cleaning unit 15 as will be described later. it can.

Next, the pressurized water cleaning unit 15 will be described.
The pressurized water cleaning unit 15 includes a roll brush 21b, a relay pressing brush 231, a low-speed pressing brush 232, and pressurized water supply pipes 321 and 322. The configuration of the roll brush 21b and the interval between the rotation shafts are the same as those of the roll brush 21a of the preliminary cleaning unit 12, and the roll brush 21b rotates in the same direction by a chain (not shown) common to the roll brush 21a. Note that the length of the bristles of the roll brush 21b may be the same as the length of the bristles of the roll brush 21a, but the bristles of the roll brush 21b may be shorter than the bristles of the roll brush 21a. In this case, the radish 41 is stabilized as will be described later.

The relay pressing brush 231 and the low-speed pressing brush 232 are arranged so as to face a part (second half part) of the second and fourth roll brushes among the four roll brushes 21b. As will be described later, the relay pressing brush 231 is attached so as to swing up and down around a fulcrum, and the low-speed pressing brush 232 is fixed. The relay pressing brush 231 is preferably attached so as to swing, but may be fixed.
The bristle of the relay presser brush 231 uses the same hardness as the presser brush 22a1 of the preliminary cleaning unit 12, and the bristle of the low speed presser brush 232 uses the same hardness as the low speed presser brush 22a2 of the preliminary cleaning unit 12. ing. That is, the bristles of the low-speed presser brush 232 are softer than the bristles of the relay presser brush 231.
As will be described later, the relay press brush 231 has a function of moving the radish 41 to the next roll brush, and the low-speed press brush 232 has a function of reducing the release speed (movement speed) of the radish.
The low-speed presser brush 232 may have the same configuration as the relay presser brush 231, but by reducing the speed of the radish by the low-speed presser brush 232, the radish is gently transferred from the pressurized water cleaning unit 15 to the finish cleaning unit 13 as will be described later. I can move.
The pressurized water supply pipes 321 and 322 are arranged between two adjacent roll brushes among the four roll brushes 21b so as to be parallel to the rotation axis of the roll brush 21b.

Next, the movement and cleaning of the radish of the cleaning machine will be described.
The radish 41 supplied from the supply unit 11 advances to the pressurized water cleaning unit 15 side while rotating between the roll brush 21b and the presser brush 22a of the preliminary cleaning unit 12, and is discharged to the pressurized water cleaning unit 15. The speed when the radish 41 is discharged to the pressurized water washing unit 15 varies depending on the hardness of the hair of the low speed brush 22a2, but the hair of the low speed brush 22a2 is softer than the hair of the presser brush 22a1, The radish 41 is gently discharged to the pressurized water washing unit 15 at a low speed, and smoothly moves between the first and second of the roll brush 21b. If the hair of the low-speed brush 22a2 has the same hardness as the hair of the presser brush 22a1, the discharge speed of the radish 41 becomes too fast, and the radish 41 may advance so as to run through the pressurized water washing unit 15. There are cases where the pressurized water cleaning cannot be performed effectively.

  The presser brush 22a of the preliminary cleaning unit 12 is divided into a presser brush 22a1 and a low-speed presser brush 22a2, so that the presser brush 22a1 is set to a hardness suitable for cleaning with priority on the cleaning effect. Priority can be given to slowing down the release rate of radish, and it can be set to a hardness suitable for the release rate. That is, the presser brush 22a can set the hardness of the hairs of the presser brush 22a1 and the low-speed presser brush 22a2 separately according to each purpose. Therefore, it becomes easy to set the hardness of the hair of the presser brush 22a.

The radish 41 that has moved between the first and second roll brushes 21b of the pressurized water washing unit 15 rotates together with both roll brushes. During the rotation, the radish 41 does not come into contact with any presser brush, and therefore continues to rotate at that position. Here, when the bristle of the roll brush 21b is shorter than the bristle of the roll brush 21a, the radish 41 is placed deeply between the first and second roll brushes, and rotates stably between the two roll brushes.
When the radish 41 rotates between the first and second of the roll brush 21b, the radish 41 is washed with pressurized water (for example, 25 MPa pressurized water) sprayed from the nozzle of the pressurized water supply pipe 321 to the end. Since the radish 41 is rotating, the pressurized water is sprayed evenly over the entire surface of the radish 41, and the remaining soil and the like that cannot be removed by the preliminary washing unit 12 of the radish 41 is almost completely removed.

  When the next radish is discharged from the pre-cleaning section 12, the radish 41 rotating between the first and second of the roll brush 21b is pushed into the discharged radish and the second and third rolls. Move between brushes. Since the radish 41 that has moved between the second and third roll brushes contacts the relay presser brush 231, the radish 41 proceeds to the finish cleaning unit 13 side without rotating between the two roll brushes, and the third and fourth rolls. Move between brushes. And the radish 41 which moved between the 3rd and 4th roll brush rotates between both roll brushes until it is extruded to the next radish. The radish 41 rotating between the third and fourth roll brushes is washed with pressurized water sprayed from the nozzles of the pressurized water supply pipe 322 in a divergent manner. When the radish 41 rotating between the third and fourth roll brushes is pushed out to the next radish, the radish 41 moves from between the two roll brushes to the finish cleaning unit 13. At that time, since the radish 41 comes into contact with the low-speed presser brush 232, the radish 41 is gently and smoothly released (moved) to the finish cleaning unit 13.

The number of roll brushes 21b in the pressurized water washing unit 15 may be at least two, but if the number of roll brushes 21b is increased to increase the number of pressurized water supply pipes 321 and 322, the radish soil and the like are more completely removed. be able to. When the number of roll brushes 21b is increased, the number of roll brushes 21a and presser brushes 22a in the preliminary cleaning unit 12 can be reduced. When there are two roll brushes, only the low speed press brush 232 is provided without providing the relay press brush 231. In that case, the low-speed presser brush 232 also serves as a relay presser brush.
The radishes 41 that have moved to the finish cleaning section 13 are sequentially aligned with the discharge table 132, rinsed with shower-like fresh water supplied from the shower water supply pipe 31, and finish cleaning is performed. At that time, the radish 41 does not rotate, but the soil or the like adhering to the radish 41 is almost completely removed (washed off) by the previous cleaning section. Therefore, the finishing cleaning section 13 sprays shower water to clean the previous stage. It is only necessary to wash off the washing water adhering to the part. Therefore, even if the radish 41 on the discharge table 132 does not rotate, it does not hinder the finish cleaning.

  When the washing efficiency of the washing machine of the present invention provided with the pressurized water washing unit 15 and the conventional washing machine not provided with the pressurized water washing unit 15 is washed, when cleaning the radish of 300 cases (3000), the washing after the washing is According to the conventional washing machine, 2.5 people took 2.5 hours, but according to the washing machine of the present invention, it can be done by 2 people in 1.5 hours.

2 will be described in detail with reference to FIG.
FIG. 2A shows an example of pressurized water supply officers 321 and 322, and both pressurized water supply officers are provided with a predetermined number of nozzles 33. About five nozzles 33 are provided when the length of the roll brush 21b of the pressurized water washing unit 15 is about 60 cm, for example. Pressurized water is supplied to the pressurized water supply officers 321 and 322 from a pressurizing pump (not shown).
FIG. 2B shows an example of an attachment portion of the relay pressing brush 231. The relay pressing brush 231 is slidably attached to the support member 52 by a hinge 51 or the like. Since the relay presser brush 231 swings up and down according to the thickness of the radish that passes, the radish 41 can be smoothly relayed (moved) to the next roll brush even when the thickness of the radish is different. FIG. 2C shows an example of a support portion for the relay pressing brush 231, the low-speed pressing brush 232, and the pressurized water supply officers 321 and 322. Each vertical support member 53 is attached so as to be slidable on the horizontal support member 54, and can be fixed to a predetermined position by sliding vertically and horizontally. Therefore, the relay pressing brush 231, the low-speed pressing brush 232, and the pressurized water supply officers 321 and 322 can slide their vertical support members 53 in the vertical direction to set their heights to predetermined heights. The support member 53 can be slid in the horizontal direction, and the position in the horizontal direction can be set to a predetermined position.

FIG. 2D is a diagram for explaining the movement of the radish by the roll brush and the presser brush in the pressurized water cleaning unit 14.
The low-speed presser brush 22a2 of the preliminary cleaning unit 12 is opposed to the front side (preliminary cleaning unit 12 side) of the roll brush 21b and the relay presser brush 231 is rearward of the top of the roll brush 21b (finish cleaning). It faces the part 13 side). Therefore, the radish 41 between the roll brushes 21b and 21b does not come into contact with any presser brush. Since the roll brushes 21b and 21b rotate in the direction of the arrow P1, the radish 41 rotates in the direction of the arrow P3 and continues to rotate between the two roll brushes. When the next radish is discharged from the low-speed presser brush 22a2 in this state, the radish 41 is pushed out by the discharged radish and moves to the roll brush 21b c side. At that time, the radish 41 comes into contact with the relay presser brush 231, so that it does not stay between the roll brushes 21b and 21b and moves between the roll brushes 21b and 21b.

The radish 41 that has moved between the roll brushes 21b and 21b does not come into contact with any presser brush, and therefore continues to rotate at that position. In this state, when the next radish is released from the low-speed presser brush 22a2, the radish 41 between the roll brushes 21b and 21b is pushed and moved toward the low-speed presser brush 232 side. At that time, since the radish 41 comes into contact with the low-speed presser brush 232, the radish 41 is gently discharged to the finish cleaning unit 13.
When the number of roll brushes 21b is increased to four or more, the number of roll brushes 21b is increased in units of two, a relay pressing brush 231 is provided for each two, and the low-speed pressing brush 232 is provided for the last two.

  FIG. 2 (e <b> 1) is a diagram illustrating a state where the radish 41 moves from the pressurized water cleaning unit 15 to the finishing cleaning unit 13. When the roll brush 21b is rotated, the radish 41 pushes and bends the bristles 222 of the low-speed presser brush 232 and proceeds to the finish cleaning unit 13 side. When the radish 41 is between the roll brush 21 b and the low-speed presser brush 232, the radish 41 closes the space between the two brushes, so that the cleaning water on the pressurized water cleaning unit 14 side (water that has cleaned the soil, etc.) Is not carried to (does not move). Further, when the radish 41 leaves the roll brush 21b and the low-speed presser brush 232, the bristles 221 and 222 of the both brushes block between the two brushes. It is not carried to 13 (does not move).

  FIG. 2 (e2) is an example in which the finishing washing water tray 16 is provided below the discharge table 132 in FIG. 2 (e1). The finishing washing water tray 16 extends from the bottom of the discharge table 132 to the roll brush 21b. It extends and is formed so as to wrap around the substantially lower half of the roll brush 21b. The fresh water sprayed from the shower water supply pipe 31 in FIG. 1 is collected in the finishing washing water receiving tray 16 after washing the radish on the drainage-like discharge stand 132. The water 161 collected in the finish washing water receiving tray 16 has its water level set so that substantially half of the roll brush 21 b is immersed, and the water 161 overflowing from the finishing washing water receiving tray 16 flows into the water tank 14.

In the case of FIG. 2 (e2), the roll brush 21b (the roll brush opposed to the low-speed presser brush 232) scoops up the water 161 accumulated in the finish washing water tray 16 and does not scoop up the water 141 in the water tank 14. In FIG. 2 (e1), even if the washing water of the pressurized water washing unit 15 adheres to the radish 41 and is carried to the finish washing unit 13, the carried washing water is less contaminated. Accordingly, in the case of FIG. 2 (e2), the cleaning effect of the finish cleaning unit 13 is further enhanced.
The bottom surface of the finish washing water receiving tray 16 may have a flat shape so that substantially half of the roll brush 21b is immersed in the water 161, even if the bottom surface is not a shape that wraps the roll brush 21b.

A washing machine according to Embodiment 2 of the present invention will be described with reference to FIG.
Fig.3 (a) shows the structure of the pressurized water washing | cleaning part among the washing machines of Example 2 (illustration of the pressurized water supply pipe and the nozzle is abbreviate | omitted). The configurations of the preliminary cleaning unit and the finishing cleaning unit are the same as those of the cleaning machine of FIG.
In the pressurized water cleaning section of FIG. 3A, a portion corresponding to the roll brush 21b of FIG. 1 is configured by roll brushes 21b1, 21b2 and hairless rolls 21c1, 21c2. The roll brush and the hairless roll are alternately arranged like a roll brush 21b1, a hairless roll 21c1, a roll brush 21b2, and a hairless roll 21c2. One relay pressing brush 231 is provided for the roll brush 21b1 and the hairless roll 21c1, and one low-speed pressing brush 232 is provided for the roll brush 21b2 and the hairless roll 21c2. That is, the relay pressing brush 231 and the low-speed pressing brush 232 are provided for each pair of roll brush and hairless roll.

If the roll brush 21b is entirely made of roll brass as shown in FIG. 1, the radish is placed in an unstable state on the hair of the brush, so when pressurized water is sprayed onto the radish, the radish Rotation in the direction of travel (direction orthogonal to the rotation axis of the roll brush and the hairless roll) may cause a change in direction (turn), and the orientation of the radish may become messy and may not align regularly. That is, the radish may not move side by side in a direction parallel to the rotation axis of the roll brush.
On the other hand, in the case of FIG. 3A, since the roll brush and the hairless roll are alternately arranged, the radish is stably supported by the hairless roll, and even if the radish tries to turn in the direction of travel. Since the contact resistance between the radish and the hairless roll is small, the radish is prevented from turning at the portion of the hairless roll. Therefore, in the case of FIG. 3A, the radish moves in parallel with the rotation axis of the roll brush and the hairless roll without turning in the traveling direction.

  3A, when the roll brushes 21b1 and 21b2 are also hairless rolls, that is, when all of the roll brushes 21b1 and 21b2 and the hairless rolls 21c1 and 21c2 are hairless rolls, the radish is adjacent to the hairless roll. The pressure washing water hits only the surface (upper surface) of the radish and does not hit the back surface (lower surface), so that the back surface cannot be cleaned. Therefore, by alternately arranging the roll brush and the hairless roll, the radish can be kept parallel to the rotation axis of the roll brush and the hairless roll, and the surface of the radish can be washed evenly by rotating the radish with the roll brush. .

The diameter (size between the hair tips) Db of the roll brush 21b1 in FIG. 3A and the diameter Dc of the hairless roll 21c1 may be substantially the same, but either one may be larger and the other may be smaller. The same applies to other roll brushes and hairless rolls.
The hairless roll may be formed of plastic, metal, wood, or the like, or may be formed by coating metal or wood with plastic. Moreover, you may coat | cover with plastics, such as a vinyl chloride, so that the outer periphery of the hair of the roll brush 21b1 may be covered like the hairless roll 21c1 of FIG.3 (c). The surface of the hairless brush is formed smoothly in any case.

Next, looking at how the wash water splatters with the roll brush and the hairless roll, the roll brush rotates with a lot of water between the hairs. The roll does not splash water around. Therefore, when the roll brush and the hairless roll are arranged as shown in FIG. 3 (a), the hairless roll 21c2 is located on the finish cleaning section side (the last part of the pressure water cleaning section). Is less scattered to the finish cleaning section, and the stain of the finish cleaning water can be reduced.
In the case of FIG. 3 (a), the relay presser brush 231 and the low-speed presser brush 232 are provided, and the radish is moved from the roll brush 21b1 to the hairless roll 21c2 and further toward the finish cleaning unit. The radish on the roll is pushed by the succeeding radish sent from the pre-cleaning section and sequentially moves to the finish cleaning section, so the relay pressing brush 231 and the low-speed pressing brush 232 can be omitted. The low-speed presser brush 232 also has a function of preventing the dirty water from the pressurized water cleaning unit from being carried to the finishing cleaning unit. However, when the roll brush and the hairless roll are arranged as shown in FIG. As described above, since the dirty water in the pressurized water washing unit rarely scatters to the finish washing unit, even if the low-speed presser brush 232 is omitted, the water splashed (carried) from the pressurized water washing unit to the finish washing unit. Will be less. The low-speed presser brush 232 is not a brush but may be a warm sheet such as a plastic sheet for preventing water from scattering.

The finish cleaning unit 13 of FIG. 1 includes a discharge stand for aligning radishes and a shower water supply pipe. However, when a roll brush and a hairless roll are used as shown in FIG. Since water stains are reduced, a drain tank and a shower water supply pipe may be omitted, and a tank containing the finishing washing water may be used, and the radish may be discharged directly from the pressurized water washing unit to the tank. . The radish released into the aquarium can be rinsed clean by simply scooping or picking it up. In addition, what is necessary is just to always supply new water from the water supply or the pump for the water in the water tank.
When using a water tank in which the finishing washing water is stored in the finishing washing section, it is not necessary to align the radish discharged from the pressurized water washing section to the discharge stand, so the speed of the radish discharged from the pressurized water washing section to the finishing washing section. May be fast. Therefore, when using a water tank in which finishing cleaning water is stored in the finishing cleaning section, the low-speed presser brush 232 need not be provided.

  Although the said Example demonstrated the washing | cleaning of the radish as an example, the washing | cleaning of root vegetables, such as not only a radish but a carrot, a beef bowl, and a candy, is possible.
