Description

  The present invention relates to a rotating brush and a transport cleaning device for cleaning vegetables while transporting them in the longitudinal direction.

Vegetables sold in supermarkets and the like are generally processed so as to have a beautiful appearance in order to improve the consumer's desire to purchase. That is, harvested vegetables are washed, polished, sorted, sorted, packaged, etc. and shipped.
In particular, root vegetables (eg, radish, carrots, potatoes, sweet potatoes, long bean paste, etc.) are mud, and are conventionally known to be washed while being conveyed in the longitudinal direction by a plurality of rotating brushes (for example, (See Patent Document 1).
Japanese Patent No. 3388441

  In the conventional transport cleaning apparatus, two types of rotating brushes are used in combination. The first rotating brush includes a brush main body, a peripheral brush made of hair planted on the outer peripheral surface of the main body, and a spiral brush extending spirally in the transport direction on the outer peripheral surface. The second rotating brush includes a brush main body, a peripheral brush made of hair planted on the outer peripheral surface of the main body, and a ring brush arranged at intervals on the outer peripheral surface in the transport direction. The spiral brush and the ring brush extend longer than the peripheral brush, and effectively remove, for example, mud adhering to the radish recess.

  However, since the spiral brush of the first rotating brush is set to have a large width, a large resistance is generated when it is brought into contact with the second rotating brush. Therefore, if the distance between the first rotating brush and the second rotating brush is increased, the gap between the first rotating brush and the second rotating brush becomes too large, and it becomes difficult to convey a relatively small object.

  An object of the present invention is to reduce the resistance acting on each rotating brush even if the distance between the rotating brushes is shortened in the rotating brush and the transport cleaning device.

The rotating brush according to claim 1 is for cleaning the object to be cleaned while conveying the object to be cleaned in the longitudinal direction, and is inclined in the conveying direction with a main body having a circular outer peripheral surface extending in the conveying direction of the object to be cleaned. The peripheral brush which consists of the hair planted on the outer peripheral surface of the main body in the state, and the spiral brush which is planted spirally on the outer peripheral surface of the main body and consists of the hair longer than the peripheral brush is provided.
In this rotating brush, since the peripheral brush and the spiral brush are combined, the cleaning ability for the object to be cleaned is remarkably improved. Particularly, the width of the spiral brush can be reduced because the hair of the peripheral brush is inclined and the force for conveying the object to be cleaned is high. Therefore, even if the distance between the rotating brushes is shortened and the spiral brush is in contact with another rotating brush, the resistance acting on each rotating brush is reduced.

According to a second aspect of the present invention, in the rotary brush according to the first aspect, the width of the spiral brush is 3/4 or less of the pitch of the spiral brush.
In this rotating brush, since the width of the spiral brush is set to be small, the resistance acting on each rotating brush when the spiral brush is in contact with another rotating brush is reduced.

According to a third aspect of the present invention, in the rotary brush according to the second aspect, the width of the spiral brush is ½ or less of the pitch of the spiral brush.
In this rotating brush, since the width of the spiral brush is set to be small, the resistance acting on each rotating brush when the spiral brush is in contact with another rotating brush is reduced.

In the rotating brush according to a fourth aspect, in any one of the first to third aspects, the hair of the spiral brush extends vertically from the outer peripheral surface.
This rotating brush has a higher cleaning capability because the tip of the spiral brush contacts the object to be cleaned.

According to a fifth aspect of the present invention, in the rotary brush according to any one of the first to fourth aspects, the spiral brush is composed of a plurality of brush bristle bundles, and the brush bristle bundles form a plurality of rows in the extending direction of the spiral.
In this rotating brush, since a gap is secured between the bristle bundle rows, the bristle bundles do not have a great resistance against each other during deformation. That is, the flexibility of the brush bristle bundle is maintained.

The rotary brush according to claim 6 is the rotary brush according to claim 5, wherein the brush hair bundles of the spiral brush are arranged in four rows or less.
In this rotating brush, since the number of rows of brush bristles is set to be small, the resistance acting on each rotating brush when the spiral brush is in contact with another rotating brush is reduced.

According to a seventh aspect of the present invention, in the rotary brush according to the sixth aspect, the brush hair bundles of the spiral brush are arranged in three rows.
In this rotating brush, since the number of rows of brush bristles is set to be small, the resistance acting on each rotating brush when the spiral brush is in contact with another rotating brush is reduced.

In the rotating brush according to an eighth aspect, in any one of the first to seventh aspects, the length of the hair of the spiral brush is in a range of 2 to 3 times the length of the hair of the circumferential brush.
In this rotating brush, since the ratio of the length of the hair of the spiral brush and the length of the hair of the peripheral surface brush is appropriately set, the cleaning ability for the object to be cleaned is improved.

In the rotating brush according to claim 9, in any one of claims 1 to 8, the length of the hair of the peripheral brush is in the range of 10 to 50 mm, and the length of the hair of the spiral brush is in the range of 15 to 100 mm. It is in.

In the conveyance cleaning apparatus of Claim 14, in Claim 12 or 13, the spiral brush of one rotating brush is in contact with the peripheral surface brush of the other rotating brush.
In this apparatus, since the spiral brush and the peripheral surface brush are in contact with each other, the cleaning ability for the object to be cleaned is improved.

According to a fifteenth aspect of the present invention, in the fourteenth aspect, the two rotating brushes are disposed close to each other, and a gap is secured between the peripheral surface brushes.
In this apparatus, since two rotating brushes are arranged close to each other, an object to be cleaned can be transported between the two rotating brushes. In addition, since a gap is secured between the peripheral brushes, a large resistance does not act on each other.

In the conveyance washing apparatus of Claim 16, in Claim 15, a clearance gap is the range of 1-30 mm.
In this apparatus, since the size of the gap between the peripheral brushes is appropriately set, the object to be cleaned can be reliably conveyed without being damaged.

According to a seventeenth aspect of the present invention, in any one of the twelfth to sixteenth aspects, the two rotating brushes rotate in the same direction at the same speed. The spiral brushes of the two rotating brushes have the same shape and are out of phase so as not to contact each other.
In this apparatus, since the spiral brushes do not contact each other, a large resistance does not act on each rotating brush.

The transport cleaning apparatus according to claim 18 is a state in which the rotating brush according to any one of claims 1 to 11, a main body having a circular outer peripheral surface extending in the transport direction of the object to be cleaned, and inclined in the transport direction The second rotation having a peripheral brush made of hair planted on the outer peripheral surface of the main body and an annular brush made of hair that is planted on the outer peripheral surface of the main body and arranged in a plurality of locations side by side in the conveying direction. It has a brush.

According to a twentieth aspect of the present invention, in the transport cleaning apparatus according to the twentieth aspect, the rotating brush and the second rotating brush are arranged close to each other, and a gap is secured between the peripheral surface brushes.
In this apparatus, since two rotating brushes are arranged close to each other, an object to be cleaned can be transported between the two rotating brushes. In addition, since a gap is secured between the peripheral brushes, a large resistance does not act on each other.

In the conveyance washing apparatus of Claim 21, in Claim 20, a clearance gap is the range of 1-30 mm.
In this apparatus, since the size of the gap between the peripheral brushes is appropriately set, the object to be cleaned can be reliably conveyed without being damaged.
The transport cleaning apparatus according to claim 22 is a transport cleaning apparatus capable of simultaneously cleaning and transporting a plurality of vegetables, and includes a plurality of rotating brushes that form a U-shaped or W-shaped transport path, and a rotating brush. And a drive mechanism for driving. The plurality of rotating brushes include at least one rotating brush according to claim 1.

  In the rotating brush and the transport cleaning device according to the present invention, even if the distance between the rotating brushes is shortened in the rotating brush, the resistance acting on each rotating brush can be reduced.

  1-4, the conveyance washing apparatus 1 as 1st Embodiment of this invention is shown. 1 is a front view of the transport cleaning apparatus 1 as viewed from the carry-in side, FIG. 2 is a front view of the apparatus 1 as viewed from the carry-out side, FIG. 3 is a side view of the apparatus 1, and FIG. The transport cleaning device 1 is a device for cleaning vegetables while transporting them, and is particularly suitable for removing mud from root vegetables (radish, beef bowl, ginger, carrot, sweet potato, potato, etc.). Hereinafter, vegetables to be transported and cleaned are referred to as “objects to be cleaned D”.

  The transport cleaning apparatus 1 is mainly transported by the frame 2, the plurality of rotating brushes 3 to 5 provided on the frame 2, the drive mechanism 7 for driving the rotating brushes 3 to 5, and the rotating brushes 3 to 5. And a water supply mechanism 9 for supplying water to the object to be cleaned D.

  The frame 2 is a frame for holding another configuration at a predetermined position, and a general configuration is adopted.

The rotating brushes 3, 4, 5 extend long in the longitudinal direction of the frame 2 (conveying direction of the object to be cleaned D), and are arranged close to each other in parallel. The rotating brushes 3, 4 and 5 are substantially the same type (the length and diameter are the same). Hereinafter, the description on the left and right of the figure is the case with reference to FIG.
As shown in FIG. 1, the first rotating brush 3, the second rotating brush 4, and the third rotating brush 5 are arranged in this order from the right side of the drawing. The vertical position of the first rotating brush 3 is slightly higher than the vertical position of the second rotating brush 4. For this reason, the first rotating brush 3 is disposed diagonally to the upper right of the second rotating brush 4. The vertical position of the third rotating brush 5 is higher than the vertical position of the first rotating brush 3. Therefore, the third rotating brush 5 is disposed obliquely above and to the left of the second rotating brush 4. Summarizing the above positional relationship, the rotation center becomes higher in the order of the third rotating brush 5, the first rotating brush 3, and the second rotating brush 4.

The object to be cleaned D is generally transported at the upper side between the first rotating brush 3 and the second rotating brush 4 and at a position between them, and is mainly transported and cleaned by the first rotating brush 3 and the second rotating brush 4. . Further, when the object to be cleaned D is bounced to the left from between the first rotating brush 3 and the second rotating brush 4, the first rotating brush 3 and the second rotating brush 4 come into contact with the third rotating brush 5 again. Is returned to the conveyance path between. That is, the third rotating brush 5 has not only a cleaning / conveying function but also a splash prevention and return function. Further, on each side wall of the frame 2, a first plate 28 that extends to above the first rotating brush 3 and a second plate 29 that extends to above the third rotating brush 5 are provided. The plates 28 and 29 prevent the object to be cleaned D from jumping out of the rotating brushes 3 to 5. The portions of the plates 28 and 29 that are close to the rotary brushes 3 and 5 are slanted, so that the object D to be washed up can be quickly returned to the rotary brushes 3 and 5 side.
The rotating brushes 3 to 5 are arranged at a position where the inlet side is higher than the outlet side, that is, obliquely arranged so as to become lower in the transport direction.

Next, the structure of the rotating brushes 3 to 5 will be described in detail.
As shown in FIG. 5, the first rotating brush 3 is used for cleaning the object D to be cleaned, and mainly includes a cylindrical shaft 11 and a mandrel 12 penetrating the center of the shaft 11. The peripheral brush 13 made of hair planted on almost the entire circular outer peripheral surface of the shaft 11 and the spiral brush 14 made of hair planted on the outer peripheral surface of the shaft 11 (the portion where the peripheral brush 13 is not planted). It consists of and.

  The shaft 11 extends in the conveyance direction of the article to be cleaned D and has an outer peripheral surface with a circular cross section. The shaft 11 is made of wood, for example, and can be manufactured at low cost. For example, the shaft 11 has a diameter of 20 to 30 cm and a length of 1 m80 cm to 2 m30 cm. The mandrel 12 is made of metal, for example, and both ends project from both sides of the shaft 11. The mandrel 12 is the rotation center of the shaft 11.

  The peripheral brush 13 is composed of hairs planted on the outer peripheral surface of the shaft 11 in a state of being inclined in the transport direction, and is specifically composed of a plurality of hair bundles 13a. Each hair bundle 13a is constituted by bundling several tens to several hundreds of hairs. The hair bundles 13a are planted at equal intervals in the rotation axis direction and the circumferential direction, but the hair bundles 13a adjacent to each other in the circumferential direction are arranged so as to be shifted in the rotation axis direction. It is composed. As shown in FIG. 6, each hair bundle 13a is planted with a slight inclination in the traveling direction. As described above, since the bristles of the circumferential brush 13 are inclined in the rotating brushes 3 and 4, the movement of the article to be cleaned D in the transport direction becomes smooth. Here, the inclination angle θ1 of the hair bundle 13a is set in the range of 2 to 15 degrees, and preferably in the range of 4 to 6 degrees. Thus, since the inclination of the bristles of the peripheral brush 13 is set appropriately, the ability to transport the article D to be cleaned in the transport direction is high. Moreover, the front-end | tip of each hair | bristle bundle 13a is processed so that it may extend in parallel with the advancing direction, and the whole front-end | tip of the surrounding surface brush 13 comprises the outer peripheral surface of a cylinder.

  The spiral brush 14 is made of hair that is planted spirally on the outer peripheral surface of the shaft 11 and is longer than the peripheral brush 13, and is specifically composed of a plurality of hair bundles 14 a. The hair bundles 14a are arranged in three rows in the spiraling direction. The hair bundles 14a in each row are arranged at the same circumferential position with respect to the hair bundles 14a in the other adjacent rows. Each hair bundle 14a is planted so as to extend vertically from the outer peripheral surface of the shaft 11, as shown in FIG. Each hair bundle 14a is longer than the hair bundle 13a. Further, the tips of the hair bundles 14a are processed so as to extend in parallel with the traveling direction. As described above, the spiral brush 14 has a high cleaning ability because the hair tip contacts the article D to be cleaned. Moreover, since the clearance gap is ensured between the row | line | columns of the bristle bundle 14a, the bristle bundles 14a do not become a big resistance with respect to each other at the time of a deformation | transformation. That is, the flexibility of the bristle bundle 14a is maintained. In addition, it is preferable that a brush bristle bundle is 4 rows or less.

  The bristles of the peripheral brush 13 and the spiral brush 14 are made of, for example, nylon, vinyl chloride, or polyester. The bristles of the peripheral brush 13 and the spiral brush 14 have a diameter in the range of 0.1 to 1.0 mm, and more preferably in the range of 0.2 to 4.0 mm. As described above, since the diameters of the hairs of the peripheral brush 13 and the spiral brush 14 are appropriately set, the cleaning ability for the article D to be cleaned is improved.

  The hair length L2 of the spiral brush 14 is in the range of 2 to 3 times the hair length L1 of the peripheral brush. Specifically, the length of the hair of the peripheral brush 13 is in the range of 10 to 50 mm, and the length of the hair of the spiral brush 14 is in the range of 15 to 100 mm. Thus, since the ratio of the length of the hair of the spiral brush 14 and the length of the hair of the peripheral surface brush 13 is set appropriately, the cleaning ability with respect to the cleaning object D is improved.

As shown in FIG. 7, the first rotating brush 3 and the second rotating brush 4 are arranged close to each other. Therefore, the article D to be cleaned can be transported between the two rotating brushes. A clearance S is secured between the peripheral brushes 13 of the rotary brushes 3 and 4. Therefore, a large resistance does not act on each other. The gap S is, for example, in the range of 1 to 30 mm, and more preferably in the range of 2 to 10 mm. Thus, since the size of the gap between the peripheral brushes 13 is set appropriately, the object to be cleaned D can be reliably conveyed. Specifically, even a relatively small object to be cleaned D is unlikely to fall from the conveyance path. If the gap between the peripheral brushes 13 is set to be small as described above, there is a concern that the contact amount between the spiral brush 14 and the peripheral brush 13 is increased, and the resistance to the rotary brushes 3 and 4 is increased. However, in this apparatus, since the width of the spiral brush 14 is set small, the resistance is sufficiently small.
Moreover, since the clearance gap between each rotary brush is set small, a to-be-cleaned object is hard to be damaged.

  Each winding of the spiral brush 14 of both the rotating brushes 3 and 4 is in contact with the peripheral brush 13 of the other rotating brush 3 and 4. Since the spiral brush 14 and the peripheral brush 13 are in contact with each other, the cleaning ability for the article D to be cleaned is improved. The two rotating brushes 3 and 4 rotate in the same direction and at the same speed, and the spiral brushes 14 of the two rotating brushes have the same shape and are not in contact with each other. Is off. Thus, since the spiral brushes 14 do not contact each other, a large resistance does not act on each of the rotating brushes 3 and 4.

  In FIG. 7, the width W of the spiral brush 14 is about 1/10 of the pitch P of the spiral brush 14. For this reason, when the spiral brush 14 is in contact with other rotating brushes, the resistance acting on each rotating brush is reduced. The width W of the spiral brush 14 is preferably 3/4 or less of the pitch P of the spiral brush 14, and more preferably 1/2 or less of the pitch P of the spiral brush 14. In particular, the width W of the spiral brush 14 is preferably in the range of 1/7 to 1/12 of the pitch P of the spiral brush 14.

  The width W of the spiral brush 14 is, for example, in the range of 3 to 4 cm. The pitch P of the spiral brush 14 is in the range of 30 to 40 cm, for example.

  The third rotating brush 5 is disposed close to or in contact with the second rotating brush 4. In this embodiment, the third rotating brush 5 is a normal rotating brush that is entirely covered with a circumferential brush composed of bristles of the same length.

  The drive mechanism 7 includes a first motor 16, a first chain 18, a second chain 19, a third chain 20, and sprockets 22 to 24 that are respectively fixed to a rotating brush. It is configured. The first chain 18 is stretched between the first sprocket 21 and the second sprocket 22 of the first motor 16. The second chain 19 is stretched between the second sprocket 22 and the third sprocket 23. The third chain 20 is stretched between the third sprocket 23 and the fourth sprocket 24. As described above, when the first motor 16 is operated, the rotating brushes 3 to 5 rotate in the same direction (counterclockwise in FIG. 1) at the same speed.

  The water supply mechanism 9 is a mechanism for supplying water to an object to be cleaned while pressurizing water, and is characterized by changing the water supply direction. The water supply mechanism 9 includes a plurality of (five) shower pipes 31, a second motor 32 for swinging the shower pipes 31, and a plurality of link mechanisms 33 that connect the shower pipes 31. . As shown in FIGS. 3 and 4, the shower pipe 31 is arranged side by side in the transport direction above the rotating brushes 3 to 5. As shown in FIG. 2, each shower pipe 31 extends in a direction orthogonal to the transport direction and is rotatably supported by the frame 2. Each shower pipe 31 has a plurality (three) of nozzles 34 facing downward. Each link mechanism 33 includes a disc 37 fixed to one end of each shower pipe 31 and links 38 that connect the discs alternately in the vertical direction. The second motor 32 is fixed downstream of the upper surface of the frame 2 in the transport direction. The second motor 32 and the shower pipe 31 on the downstream side in the conveying direction connect the disc 39 fixed to the second motor 32 and the protrusion 40 fixed to the shower pipe 31 and extending upward from the disc 37. Are connected to each other by a link 41. Further, each shower pipe 31 has a connecting portion 35 at the end opposite to the disc 37. The connecting portion 35 is rotatably connected to a long pipe 45 that extends in the transport direction. The long pipe 45 is connected to a water supply pump (not shown). With the above configuration, when the second motor 32 operates, each shower pipe 31 swings within a predetermined angle range by the link mechanism 33. Therefore, the shower pipe 31 supplies water downward in a predetermined angle range in the transport direction. As a result, the object to be cleaned D is sprayed with water from various angles over a wide position in the transport direction.

  The operation of the transport cleaning apparatus 1 will be described. The rotating brushes 3 to 5 rotate in the same direction. When the object to be cleaned D is supplied to the entrance of the conveyance path, the object to be cleaned D is mainly conveyed between the first rotating brush 3 and the second rotating brush 4. At that time, the hair bundle brush of each of the rotating brushes 3 and 5 cleans the object D while being supplied with pressurized water from the water supply mechanism 9. A force acts in the transport direction mainly on the object D to be cleaned due to the inclination of the peripheral brush 13, and a force in the transport direction and the rotation direction also acts on the spiral brush 14. Accordingly, the object to be cleaned D moves in the transport direction while rotating itself.

  Even when the object to be cleaned D is a radish and is relatively uneven, the spiral brush 14 reliably cleans the recess. In particular, since the spiral brush 14 is continuous in the transport direction, it is in contact with the concave portion for a long time, so that the cleaning ability is high.

(The invention's effect)
In the rotating brushes 3 and 4, since the peripheral brush 13 and the spiral brush 14 are combined, the cleaning ability for the cleaning object D is remarkably improved. In particular, the width of the spiral brush 14 can be reduced because the hair of the peripheral brush 13 is inclined and the force for conveying the article D to be cleaned is high. Therefore, the resistance acting on each rotating brush when the spiral brush 14 is in contact with another rotating brush is reduced.

  Further, since the width of the spiral brush 14 can be reduced, the friction acting on the object to be cleaned D is reduced, and as a result, the product is hardly damaged.

(Other embodiments)
The above embodiment is merely an example of the present invention and does not limit the present invention.
Second Embodiment
8 and 9 show a second embodiment. In the second embodiment, a rotating brush 51 provided with a spiral brush and a second rotating brush 52 provided with an annular brush are combined. The rotating brush 51 is the same as the rotating brushes 3 and 5 of the above embodiment.
As shown in FIG. 8, the second rotating brush 52 is planted on the outer peripheral surface of the shaft 55 that is inclined in the transport direction and the shaft 55 having a circular outer peripheral surface that extends in the transport direction of the cleaning object D. And a circular brush 57 that is longer than the peripheral brush 56 and is planted in a plurality of locations (five locations) along the conveying direction on the outer peripheral surface of the shaft 55. By combining the rotary brush 51 and the second rotary brush 52 in this way, the cleaning ability for the article D to be cleaned is further improved.

  In FIG. 8, the width W of the annular brush 57 is about 1/10 of the length L between the annular brushes 57. For this reason, when the annular brush 57 is in contact with another rotating brush, the resistance acting on each rotating brush is reduced. The width W of the annular brush 57 is preferably 3/4 or less of the length L between the annular brushes 57, and is 1/2 or less of the length L between the annular brushes 57. More preferably. In particular, the width W of the annular brush 57 is preferably in the range of 1/7 to 1/12 of the length L between the annular brushes 57.

  The width W of the annular brush 57 is, for example, in the range of 3 to 4 cm. The length L between the annular brushes 57 is in the range of 30 to 40 cm, for example.

  The annular brush 57 is planted in an annular shape on the outer peripheral surface of the shaft 55 and is made of hair that is longer than the peripheral brush 56. Since the material, shape, and arrangement of the annular brush 57 are the same as those of the spiral brush of the above embodiment, the description thereof is omitted.

  The bristles of the circumferential brush 56 and the annular brush 57 are planted at equal intervals in the rotation axis direction and the circumferential direction. The bristles of the circumferential brush 56 are configured in three rows in the circumferential direction, and each row is arranged at the same circumferential position as the bristles in the other adjacent rows.

  As shown in FIG. 9, the rotary brush 51 and the second rotary brush 52 are arranged close to each other, and a gap S is secured between the peripheral brushes 13 and 56. Since the two rotating brushes 51 and 52 are arranged close to each other as described above, the object to be cleaned D can be conveyed between the two rotating brushes 51 and 52. Moreover, since the clearance gap S is ensured between the surrounding brushes 13 and 56, a big resistance does not act with respect to each other.

  The gap S is, for example, in the range of 1 to 30 mm, and more preferably in the range of 2 to 10 mm. Thus, since the size of the gap between the peripheral brushes is appropriately set, the object to be cleaned can be reliably conveyed.

  The spiral brush 14 of the rotating brush 51 is in contact with the peripheral brush 56 of the second rotating brush 52, and the annular brush 57 of the second rotating brush 52 is in contact with the peripheral brush 13 of the rotating brush 51. Since the spiral brush 14 and the peripheral surface brush 56 are in contact with each other, and the annular brush 57 and the peripheral surface brush 56 are in contact with each other, the cleaning ability for the article D to be cleaned is improved.

<Third Embodiment>
In the transport cleaning apparatus shown in FIGS. 10 and 11, the water supply mechanism 60 connects the single shower pipe 61, the second motor 62 for swinging the shower pipe, and the shower pipe 61 and the second motor 62. And a link mechanism 63.

  As shown in the figure, the shower pipe 61 is disposed above the rotating brushes 3 to 5 in parallel with the conveying direction and is rotatably supported by the frame 2. The shower pipe 61 has a plurality of nozzles 64 facing downward. The second motor 62 is fixed downstream of the upper surface of the frame 2 in the transport direction. The link mechanism 63 includes a disc 69 fixed to the second motor 62, a protrusion 70 fixed to the shower pipe 61, and a link 71 that connects the two. Furthermore, the shower pipe 61 has a connecting portion 75 at the end opposite to the protruding portion 70. The connection part 75 is connected to a water supply pump (not shown).

  With the above configuration, when the second motor 62 operates, the shower pipe 61 swings within a predetermined angle range by the link mechanism 63. Accordingly, the shower pipe 61 supplies water downward in a predetermined angle range in a direction perpendicular to the transport direction. As a result, the object to be cleaned D is sprayed with water from various angles over a wide position in the transport direction.

<Fourth embodiment>
The rotating brush composed of the combination of the peripheral brush and the spiral brush in the above-described embodiment can be used in addition to the transport cleaning device. In particular, the rotating brush can be used in combination with other rotating brushes (for example, a normal rotating brush having neither a spiral brush nor an annular brush).

<Fifth Embodiment>
The third rotating brush 5 may be a rotating brush with a spiral brush or a rotating brush with an annular brush. Furthermore, the third rotating brush 5 may be omitted, and another structure for returning the object to be cleaned D to the conveyance path may be provided instead.

<Sixth Embodiment>

<Seventh embodiment>
When both the first rotating brush and the second rotating brush are provided with spiral brushes, the bunch of peripheral brushes of one or both rotating brushes may extend vertically from the outer peripheral surface.

<Eighth Embodiment>
The aforementioned transport cleaning apparatus can be used in combination with other apparatuses. For example, a plurality of lines may be formed by combining the above-described transport cleaning apparatus, or a draining device may be provided at the subsequent stage of the transport cleaning apparatus.

<Ninth Embodiment>
With reference to FIG. 12, an embodiment of a conveying and cleaning apparatus for peeling vegetables, fruits, removing mud, and polishing and cleaning will be described. The effect obtained in this embodiment is the same as the effect obtained in the above embodiment.
A transport cleaning device 81 shown in FIG. 12 is a device for transporting and cleaning a plurality of relatively small vegetables such as carrots, potatoes, and sweet potatoes while simultaneously rotating a rotating brush. In particular, the apparatus 81 can be used for transporting and washing vegetables and fruits having unevenness such as nanban, potato, and sweet potato. The device can also be applied to onion skinning.

  The transport cleaning device 81 mainly includes a frame 82, a plurality of (eight) rotating brushes 83 that are provided on the frame 82 and transport the object to be cleaned while cleaning, and a drive for driving the rotating brush 83. It is comprised from the mechanism 84 and the water supply mechanism (not shown) for supplying water to the rotating brush 83 side.

  As is clear from the drawing, the rotary brush 83 forms a semicircular, U-shaped, or W-shaped conveyance path that opens upward. Thereby, a plurality of cleaning items are simultaneously conveyed and cleaned.

The rotating brush 83 is composed of the rotating brush with spiral brush described in the above embodiment. Alternatively, the rotary brush 83 may be an appropriate combination of a rotary brush with a spiral brush and a rotary brush with an annular brush. Furthermore, the rotating brush 83 may be a combination of a rotating brush with a spiral brush and a normal rod-shaped rotating brush.
Above the rotary brush 83 at one end, a splashing prevention rotary brush 86 for preventing the object to be cleaned from jumping out of the conveyance path is disposed.

  The drive mechanism 84 includes a motor 88 provided on the upper portion of the frame 82, a chain 89 that connects the drive unit of each brush and the motor 88, and a tensioner 90 that applies tension to the chain 89. As a result, when the motor 88 is operated, the rotating brush 83 and the splashing preventing rotating brush 86 rotate in the same direction at the same speed.

  In this embodiment, since the rotating brush with the spiral brush is used, the cleaning ability for the object to be cleaned is remarkably improved. Specifically, it is possible to ideally clean or polish even the uneven portion of the southern foot, improving the quality. In addition, a southern foot can also be wash | cleaned with the conveyance washing apparatus of 1st Embodiment.

  Particularly, the width of the spiral brush can be reduced because the hair of the peripheral brush is inclined and the force for conveying the object to be cleaned is high. Therefore, when the spiral brush is in contact with another rotating brush, the resistance acting on each rotating brush is reduced.

Also in this embodiment, the rotating brushes 83 are arranged close to each other. A gap is secured between the peripheral brushes of each rotary brush 83. Therefore, a large resistance does not act on each other. The gap is, for example, in the range of 1 to 30 mm, and more preferably in the range of 2 to 10 mm. Thus, since the size of the gap between the peripheral brushes is appropriately set, the object to be cleaned can be reliably conveyed. Specifically, even a relatively small object to be cleaned is not easily dropped from the conveyance path. If the gap between the peripheral brushes is set to be small as described above, there is a concern that the contact amount between the spiral brush and the peripheral brush becomes large and the resistance to each rotating brush 83 increases. However, in this apparatus, since the width of the spiral brush is set small, the resistance is sufficiently small.
Moreover, since the clearance gap between each rotary brush is set small, a to-be-cleaned object is hard to be damaged.

  The transport cleaning device 81 may be a W-type in which two mechanisms are combined into one.
