A compression spring 18 is elastically mounted between the adjusting nut 17 screwed to the screw 4 and the lower urging plate 16,
The lower urging plate 16 is always urged downward by 8 and the urging force can be adjusted by the adjusting nut 17. In this way, the lower urging plates 16 are attached to the pair of suspension frame support frame portions 1b, respectively.
As shown in FIG. 3, both end portions of the support shaft 19 are fixed to the rear end portions of the lower urging plates 16, and the plate members 12 a constituting the rear end portions of the suspension frames 12 are fixed to the support shafts 19. Is rotatably supported. Also, as shown in FIG.
At the front end of each lower urging plate 16, the lock lever 2
1 in which the hanging frame 12 is horizontally supported by engaging the engaging metal fittings 22 attached to both ends of the hanging frame 12 on the front side with the lock lever 21. In this state, the upper brush 11 is arranged above the plurality of brush rolls 4. Further, when the lock lever 21 is disengaged from the engaging fitting 22, the entire suspension frame 12 can be rotated upward about the support shaft 19, and as shown in FIG. Open 12 whole,
The upper brush 11 can be cleaned and maintained.

The upper brush 11 has a plate-like shape in which innumerable bristles are planted on a deformable substrate 23, and is housed in the suspension frame 12. The hanging frame 12 on the upper surface of the substrate 23
An elastic material 24 such as foamed polyurethane is housed inside. In this way, the suspension frame 12 itself is biased downward by the compression spring 18, and the upper brush 1
When the substrate 23 constituting 1 is deformed, the deformed elastic material 24 tries to restore the substrate 23 to the original shape, so that the object to be cleaned is transferred between the brush roll 4 and the upper brush 11. When the suspension frame 12 is lifted up or the substrate 23 forming the upper brush 11 is deformed during the operation, the suspension frame 12 is urged downward by the action of the compression spring 18. In order to restore the substrate 23 to the original shape (plate shape) by the restoring force of the elastic material 24, the upper brush 11 is appropriately pressed against the object to be cleaned. Is adapted to the shape of the object to be cleaned, and the effect of brush cleaning is enhanced.

Further, as shown in FIG. 1, a corrugated plate-shaped guide plate 25 made of resin is disposed above the bearing portion on the front side of the roll shaft 4a of each brush roll 4. .
The guide plate 25 has a function of holding a leaf portion of a root vegetable (for example, radish) which is an object to be cleaned, and is provided on a movement locus of the object to be cleaned transferred between the brush roll 4 and the upper brush 11. It has a corresponding shape. That is, as shown in FIG. 5, the transferred object to be cleaned reaches the lowest position between the adjacent brush rolls 4 and reaches the highest position immediately above each brush roll 4 to move. The locus has a wavy shape that is similar to the shape of the upper half of each brush roll 4. Therefore, the leaves of root vegetables also move up and down along the guide plate 25. When the guide plate 25 is a flat plate, when root vegetables reach the valleys of the adjacent brush rolls 4,
Since the leaves are strongly pressed against the guide plate, root vegetables are stagnated in the valleys of the brush roll 4 or the leaves are damaged, but when the guide plate 25 is corrugated as described above, This problem is resolved and root vegetables are transferred smoothly.

Next, the shower device S, which is a characteristic part of the present invention, will be described in detail. First, the water tank 3 described above is greatly extended from the end portions of the plurality of brush rolls 4 toward the discharge side of the object to be cleaned, and the extended portions 3a
In addition, a large number of elongated plate members 26a are provided in the transfer direction P
A discharge table 26 in the shape of a cage is attached by being arranged in the transfer direction P at a predetermined interval along a direction orthogonal to. A support plate 27 for supporting the tip ends of a large number of plate members 26a forming the discharge table 26 is attached to the side surface on the discharge side of the main frame portion 1a so as to be vertically movable, and is provided on the support plate 27. When the support plate 27 is moved up and down by the elongated hole 27a and the wing nut 30 to change the fixing position thereof, as shown by a chain double-dashed line in FIG.
The mounting angle of the discharge table 26 can be changed.
A shower device S is arranged above the discharge table 26. This shower device S has a transfer direction P of the object to be cleaned.
3 shower heads 28 with a predetermined interval along
Both ends of the above are connected by a connecting pipe 29, and are attached to the outer side surface of the suspension frame support frame portion 1b via a mounting frame 31. By adjusting the fixing position of the mounting frame 31 with respect to the hanging frame support frame portion 1b, the entire shower device S can be moved in the front-back direction (direction orthogonal to the transfer direction P of the object to be cleaned), and at the same time, each shower head 28 itself. It is also rotatable so that shower cleaning can be performed most effectively according to the type and size of the root vegetables to be cleaned. Shower device S
Most of the shower water Wb ejected from the water drops and is stored in the extension portion 3a of the water tank 3 immediately below. This shower device S is used by being connected to the tap of a nearby water supply.

A delivery table 32 is attached to the end of the main frame portion 1a on the delivery side of the article to be cleaned in a forwardly inclined manner. As shown in FIGS. 2 and 5, a water discharge pipe 33 for keeping the water level of the cleaning water Wa in the water tank 3 constant is provided at the end of the water tank 3 on the feed-in side. The shower water Wb ejected from the shower device S is accommodated in the water tank 3, so that overflow water always flows out from the water discharge pipe 33. In this way, by keeping the water level of the wash water Wa in the water tank 3 constant, the lower half of the brush roll 4 is constantly immersed in the wash water Wa. In addition, in FIG. 4, reference numeral 34 denotes a discharge pipe for discharging all of the cleaning water Wa in the water tank 3.

Next, the case where the radish R, which is one of the objects to be cleaned, is continuously cleaned using the above-mentioned continuous root vegetable cleaning machine will be described. In FIG. 5, when the radish R is continuously fed from the feeding table 32, the radish R is sequentially transferred forward by the drive rotation of the plurality of brush rolls 4.
During the forward transfer, the radish R is subjected to friction between the brush roll 4 and the upper brush 11 while being sprayed with the cleaning water Wa by the brush roll 4, whereby the radish R is rubbed by the brush roll 4. Brush cleaning while rotating in the opposite direction. As described above, since the upper brush 11 appropriately presses the radish R, the brush bristles of the brush roll 4 and the upper brush 11 are well adapted to the shape of the radish R and deformed. , The leaf part is guided by the corrugated guide plate 25 corresponding to the movement locus of the radish R while being effectively brush-cleaned, so that the radish R
Is smoothly transferred forward without being subjected to excessive force.

As described above, when the radish R is brush-washed and reaches the upper end of the brush roll 4 at the end, the radish R is almost horizontal to the extension of the water tank 3 by the rotation of the brush roll 4. It is transferred to the attached discharge table 26.
Since this discharge table 26 is almost horizontal, the radish R
Can not roll, and the subsequent radish R is
By being transferred to, it is pushed from the rear and is sequentially moved to the front. As a result, several radish R are always retained on the discharge table 26. Then, at the portion of the discharge table 26, the shower water Wb is jetted downward from the shower device S mounted above the discharge table 26, so that the brush cleaning is completed and the shower water Wb remains on the discharge table 26. The shower water Wb is sprayed on the several radish R and is shaken. In this way, the radish R shower-washed for a predetermined time is sequentially pushed forward by the succeeding radish R and dropped from the tip of the discharge table 26 to be stored. By moving the support plate 27 up and down,
As described above, the mounting angle of the discharge table 26 can be changed according to the type and size of the object to be cleaned.

Most of the shower water Wb used for the shower cleaning is dropped and stored in the extension portion 3a of the water tank 3 to become the cleaning water Wa, and the shower water Wb is provided at the end of the water tank 3 on the feed side. The cleaning water Wa exceeding the set water level continues to be discharged from the discharged water pipe 33, and the water tank 3 is gradually shallowed along the transfer direction of the object to be cleaned. By the rotation of 4, the cleaning water Wa flows from the discharge side toward the supply side as indicated by the arrow Q. Therefore, the uncleaned shower water Wb is used as the cleaning water Wa, and the used dirty cleaning water Wa is discharged from the water discharge pipe 33, so that the cleaning water is not dirty or is less dirty. The object to be cleaned is washed with the water Wa. This also
The cleaning effect is enhanced.

In the above embodiment, the present invention is applied to a continuous washing machine having a plate-shaped upper brush. However, in the present invention, the upper brush has a roll shape like the lower brush roll. It can also be applied to a continuous washing machine.
