Description

  The present invention relates to a crop cleaning apparatus for cleaning a crop by jetting high-pressure cleaning water while transporting the crop.

As prior art documents related to the crop cleaning apparatus according to the present invention, for example, there is the following Patent Document 1 filed by the present applicant.
JP 2005-065702 JP

Patent Document 1 discloses a crop cleaning apparatus that cleans crops by removing deposits such as mud and soil of crops only by spraying cleaning water without using a contact cleaning body such as a brush.
This crop cleaning apparatus is configured to inject cleaning water from the top and bottom onto a transport device (conveyor) having a plurality of placement units for placing crops, a plurality of rollers for rotating the crops, and a crop placed on the placement unit. A nozzle is provided.
The mounting portion is formed in a substantially comb-like shape in which a large number of support portions formed in a downward curved shape and a large number of space portions secured between the support portions are arranged in a direction orthogonal to the transport direction. The crop is supported by the support portion, and the roller is moved in and out of the space portion along with the conveying operation of the mounting portion, and protrudes upward from the space portion in the state of being inserted.
That is, while transporting the crops supported by the support part, washing water is sprayed from above and below, the crops are lifted by rollers protruding from the space, and the roller rotates by the weight of the lifted crops. By rotating the crop and changing the position of the crop on which the washing water acts, the entire crop can be washed evenly by spraying the washing water.

  According to the crop non-contact cleaning apparatus having such a configuration, the crop is damaged by the cleaning using the contact cleaning body, and the cleaning efficiency is lowered by the soft contact cleaning body used for preventing the damage. Furthermore, it is possible to protect the crop in the cleaning operation, cleaning efficiency, and ensure cleaning, such as generation of uneven cleaning due to the difference in the surface shape of the crop.

By the way, when shipping agricultural products such as carrots and long daikon radishes as commodities, it is preferable to ensure a good and consistent appearance of the agricultural products.
Therefore, not only washing to remove mud and soil deposits of crops, but also to polish the epidermis to make it more glossy and to remove the hairy roots growing on the epidermis .
In the crop cleaning apparatus of Patent Document 1, washing water is sprayed at a high pressure so as to wash the deposits and simultaneously polish and root the crop. However, the hardness and thickness of the skin differs for each crop. Therefore, in order to perform polishing and rooting only with high-pressure jet water, it is necessary to make various adjustments such as water pressure adjustment and conveyance speed adjustment for each crop to be washed.

  An object of the present invention is to polish and root the transported crop without making various adjustments for each crop to be cleaned, while ensuring protection of the crop, cleaning efficiency, and reliable cleaning. An object of the present invention is to provide a crop cleaning apparatus that solves the problem.

In order to achieve the above object, the technical means adopted by the present invention is a crop cleaning apparatus including a transport unit that transports a crop and a nozzle unit that jets cleaning water to the transported crop. Has a plurality of roller portions that rotate in the conveying direction around the axis line in parallel along the conveying direction, and a plurality of linear convex bodies made of an elastic material project over the entire peripheral surface of the roller portion. Established,
This is a crop cleaning apparatus characterized in that all or some of the plurality of linear convex bodies are inclined and intersect with the axis of the roller portion.

  The elastic material referred to in the present invention is a rubber material or a synthetic resin material having the same elasticity as the rubber material, and is flexible enough to polish and root the crop without damaging the crop. The thing provided with is preferable.

  The linear convex body of the present invention is optional, such as embedded or pasted on the peripheral surface of the roller part, or a form in which the linear convex body and the roller part are integrally formed using an elastic material. From the viewpoint of easily and inexpensively performing the above, a form in which the linear convex body is integrally formed on the surface of the sheet-like body that can be wound around the entire circumference of the roller portion is preferable.

When all the line directions of the linear convex body are inclined and intersect with the axis of the roller part,
For example, the linear convex body is distributed so that the linear direction is reversed with respect to the selected position on the axis of the roller portion, and the linear direction of the distributed linear convex body is changed from the position to the roller portion. A configuration in which the roller portion extends in the direction opposite to the rotation direction of the roller portion is preferable.
In this case, both of the inclined angles of the distributed linear convex bodies may be the same angle or different angles.
Further, the selected position on the axis of the roller portion may be the central portion of the roller portion, or may be a position shifted in the axial direction from the central portion.

Further, when the linear direction of a part of the linear convex body is a direction that is inclined and intersects with the axis of the roller portion, for example, the linear direction is adjacent to the intersecting linear convex body in the axial direction. Is arranged with a linear convex body parallel to the axis of the roller portion, and the line direction of the intersecting linear convex body is directed from the boundary with the parallel linear convex body toward the end of the roller portion. A configuration in which the roller portion is inclined in the direction opposite to the rotation direction is preferable.
In this case, it is preferable that the intersecting linear convex bodies are arranged on both ends of the roller portion, and the parallel linear convex bodies are arranged between the linear convex bodies.
Further, the parallel linear convex body may be the central portion of the roller portion, or may be a position shifted from the central portion in the axial direction.

  Further, the intersecting linear convex bodies may be spiral.

  According to the present invention, there is provided a crop cleaning apparatus capable of polishing and rooting a transported crop without making various adjustments for each crop to be cleaned, while ensuring protection of the crop, cleaning efficiency, and reliable cleaning. Can be provided.

Hereinafter, the best mode for carrying out the crop cleaning apparatus according to the present invention will be described with reference to FIGS.
The crop cleaning apparatus 1 exemplified in this embodiment includes three cleaning units, a first cleaning unit A, a second cleaning unit B, and a third cleaning unit C, from the upstream side of the transfer to the downstream side (the transfer direction indicated by the arrow). Each of the cleaning units includes a transport unit A1, A2, A3 and a number of nozzle units N1, N2, N3 for injecting cleaning water above the transport unit A1, A2, A3. While transporting the crops by the transport units A1, A2 and A3, washing water is sprayed from the nozzles N1, N2 and N3 to the crops to remove dirt such as mud and soil from the crops. Non-contact type.
The cleaning water sprayed by the nozzle portions N1, N2, and N3 of the present embodiment has a water pressure of 6.8 Mpa to 14.7 Mpa, and further sprays cleaning water as fine water droplets of 300 drops or more per square centimeter. In addition, by such washing water jetting, deposits such as soil and mud adhering to the crop can be dropped, and fine deposits adhering so as to enter into the fine recesses of the crop can be dropped.

Hereinafter, the configuration of the crop cleaning apparatus 1 of this embodiment will be described in detail.
The first cleaning section A is a portion into which the crop with the most adhered deposit immediately after harvesting is poured. The first cleaning section A cleans the crop by spraying washing water from the nozzle portion N1 and blowing off the deposit. It is the part that polishes and roots.
The transport unit A1 of the first cleaning unit A includes a plurality of roller units 2 that are driven and rotated in the transport direction around the axis line along the transport direction.
Each of the roller portions 2 is rotatably supported by a frame (not shown). For example, from a driving source (not shown) such as a motor, a rotation transmission mechanism (such as a chain and a sprocket, or a belt and a pulley) (Not shown) are driven and rotated respectively.
The nozzle portion N1 is fixedly disposed at a position where the cleaning water can be sprayed to the valley portion 21 formed between the adjacent roller portions 2, and a plurality of the nozzle portions N1 are disposed in parallel with the axial direction of the roller portion 2. Has been.
The valley portion 21 is a portion that supports the crop, supports the crop, transports the crop while rotating it, moves it along the axial direction of the roller portion, and polishes the crop.
In this embodiment, the rotation direction around the axis of the roller portion is the transport direction, and the counter-rotation direction of the roller portion is the anti-transport direction.

A plurality of linear protrusions 3 made of a rubber material (elastic material) having flexibility enough to be deformed by contact with agricultural products are provided on the roller portion 2 over the entire peripheral surface.
Further, the linear convex body 3 is formed on the surface of the sheet-like body 31 formed in an area that can be wound around the entire circumference of the roller portion 2 using the same rubber material as the linear convex body 3. It is integrally formed with the sheet-like body 31, and the sheet-like body 31 is wound around the roller portion 2 and fixed by a well-known fixing means (not shown) such as an adhesive or uneven engagement, for example. A linear convex body 3 projects from the peripheral surface of the roller portion 2.
Further, when the linear convex body 3 cannot be expected to have a desired effect due to wear or the like, the sheet-like body 31 can be peeled off from the roller portion 2 and can be replaced with a new sheet-like body.

That is, since the linear convex body 3 can be replaced by replacing the sheet-shaped body 31, when the linear convex body 3 is worn out, it is not necessary to replace the entire roller section 2. Since it can be performed without removing, maintenance can be performed easily and inexpensively.
For example, since the roller part is connected to the rotation transmission mechanism, when the entire roller part is replaced, the rotation transmission mechanism is disassembled, removed from the frame, a new roller part is attached to the frame, and the rotation is performed. Although the troublesome work of assembling the transmission mechanism is required, such troublesome work is unnecessary if the sheet-like body is replaced as described above.
Further, since the sheet-like body 31 is naturally cheaper than the roller portion, it can contribute to cost reduction as a replacement part.

Next, the configuration of the linear convex body 3 of this embodiment will be described in detail.
As shown in FIGS. 3 and 4, the linear convex body 3 according to the present embodiment includes a linear convex body 3 </ b> A located at the central portion on the axis of the roller portion 2 of the sheet-like body 31, and both sides of the central portion. The linear convex bodies 3B are configured to be different from each other, and the linear directions of the linear convex bodies 3A and the linear convex bodies 3B are different from each other.
Specifically, the linear direction of the linear convex body 3A is made parallel to the axial direction of the roller portion 2, and the linear direction of the linear convex body 3B is set to a direction that obliquely intersects the axial line of the roller portion 2. Yes.
Further, the linear convex body 3B has a linear direction extending from the boundary portion with the linear convex body 3A toward the end and extending from the conveyance direction side to the counter conveyance direction side.
In the following description, the linear convex body 3A is referred to as a parallel linear convex body 3A, and the linear convex body 3B is referred to as an intersecting linear convex body 3B.
Moreover, it is good also as a form which exhibits spiral shape as a form of the said intersection linear convex body 3B (not shown).

3 A of parallel linear convex bodies of the said form rotate in the conveyance direction of the roller part 2, and rotate the crops mounted in the trough part 21 between the roller parts 2 in a conveyance direction, and get over the roller part 2 Apply power to
In addition, the cross-line-shaped convex body 3B having the above-described configuration rotates the crops placed on the valleys 21 between the roller parts 2 in the transport direction by rotating the roller parts 2 in the transport direction, and the axis of the roller part 2 A force is applied so as to move toward the center along the direction and to get over the roller 2.
That is, since the crop is rotated in the transport direction by the parallel linear convex bodies 3A and the cross linear convex bodies 3B, the washing water sprayed from the nozzle portion N1 acts on the entire circumference of the crop.
Further, since the crop is moved in the axial direction of the roller portion 2 by the intersecting linear convex body 3B, the washing water sprayed from the nozzle portion N1 acts on the entire length of the crop.
Further, when the roller portion 2 rotates, contact pressure acts on the crop by contact of the parallel linear convex bodies 3A and the cross linear convex bodies 3B, and the surface of the crop is caught by the crop by this contact pressure. However, at this time, the parallel linear convex bodies 3A and the intersecting linear convex bodies 3B are deformed, and further, the contact pressure escapes and the force decreases due to the rotation of the crop, so that the surface of the crop is damaged. There is nothing, and it becomes the operation | movement which slides with respect to this crop, so that it can polish and polish the skin and can root.
In addition, as described above, the parallel linear convex bodies 3A and the cross linear convex bodies 3B operate so as to slide with respect to the crops. Therefore, the certainty of the washing with the washing water and the polishing and rooting of the crop is improved.

As described above, the parts of the roller unit 2 that can get over the crops are basically the parallel linear convex bodies 3A and the intersecting linear convex bodies 3B. In order to improve the certainty of glazing and rooting, it is preferable to sequentially add crops from the intersecting linear convex 3B portion in the valley portion 21 located on the most downstream side.
That is, since the line direction of the parallel linear convex body 3A is parallel to the axis of the roller portion 2, a force is applied to the agricultural product to get over the roller portion, and the cross linear convex body 3B has its linear direction. Is crossing the axis of the roller part 2 in the above-described direction, so that a force for moving over the roller part to the crop and a force for moving toward the center part along the axis direction of the roller part are applied. It will be.
Therefore, when the crop is thrown into the intersecting linear convex 3B portion in the valley portion 21 located on the most downstream side, the intersecting linear convex 3B gradually moves to the center of the roller portion 2 while rotating the crop. The farm product that has moved over the roller portion 2 and finally moved to the central portion moves to the next valley portion 21 by the parallel linear convex bodies 3A and 3B, and further from the valley portion 21 to the next As in the valley portion 21, it moves gradually by the parallel linear convex bodies 3A and the intersecting linear convex bodies 3B, moves over the roller section 2 at the most upstream portion and moves to the second cleaning section.

Incidentally, if the angle with respect to the axis of the roller portion 2 in the linear direction of the intersecting linear convex body 3B is shallow (the direction in which the line direction of the intersecting linear convex body 3B is made parallel to the axis of the roller portion 2), the intersecting linear convex Since the linear direction of the body 3B approaches parallel to the axis of the roller part 2, the force for getting over the roller part 2 as described above exceeds the force for moving along the axis of the roller part 2.
Conversely, if the angle of the intersecting linear convex body 3B with respect to the axis of the roller portion 2 is deep (the direction in which the linear direction of the intersecting linear convex body 3B is made parallel to the transport direction), the linear direction of the intersecting linear convex body 3B Therefore, the force that moves over the roller portion 2 as described above is less than the force that moves along the axis of the roller portion 2.
Moreover, in the former, since the movement in the conveyance direction of the crop is accelerated and the amount of movement along the axis of the roller portion 2 is reduced, the contact time of the intersecting linear convex body 3B with the crop is shortened. The movement of the crops in the conveyance direction is slow, and the amount of movement along the axis of the roller unit 2 is increased, so that the contact time of the intersecting linear convex bodies 3B with the crops is increased.
That is, when washing crops with relatively soft epidermis, the angle of the intersecting linear protrusions 3B is made shallow so that the contact time with the intersecting linear protrusions 3B is shortened so that the epidermis of the crops is not excessively peeled. To prevent and clean crops with a hard epidermis, the angle of the cross-line-shaped convex body 3B is increased to increase the contact time with the cross-line-shaped convex body 3B, so that the crop can be polished and rooted reliably. It can be carried out.

5 and 6 show another form of the linear protrusion 3.
The linear convex body 3 of this embodiment is integrally formed on the surface of the sheet-like body 31 having the same structure as that of the above embodiment. Specifically, the linear direction of the linear convex body 3 is set to the axis of the roller portion 2. In order to be symmetrical with respect to the direction center as a boundary, the axis is obliquely intersected with the axis of the roller portion 2 so as to spread in the counter-conveying direction from the center in the axial direction toward both ends of the roller portion. .
Even with this form of the linear convex body 3, the crop can be rotated while being moved in the axial direction of the roller portion 2, and can be moved over the roller portion 2, and the crop can be polished and rooted. Can do.

Next, the 2nd washing | cleaning part B is demonstrated based on FIG.7 and FIG.8.
The second cleaning unit B is a part for transferring the crops from the most downstream side of the first cleaning unit A and cleaning them so as to blow off the deposits that could not be removed by the first cleaning unit A and further polishing the crops. .
The transport section A2 of the second cleaning section B has a plurality of roller sections 4 that are driven to rotate in a direction orthogonal to the transport direction with the axis as the center of rotation, the axis of the roller section 4 is directed in the transport direction, and the They are arranged in parallel along the direction orthogonal to the transport direction.
Each roller unit 4 is rotatably supported on a frame (not shown) in a state where it is inclined so that the downstream side in the transport direction is lowered, for example, from a driving source (not shown) such as a motor, Each of them is driven to rotate through a rotation transmission mechanism (not shown) such as a chain and a sprocket, or a belt and a pulley.
The nozzle portion N2 is fixedly disposed at a position where the cleaning water can be sprayed to the trough portion 41 formed between the adjacent roller portions 4, and a plurality of the nozzle portions N2 are disposed in parallel with the axial direction of the roller portion 4. Has been.
The valley 41 is a part that supports the crop, moves the crop in the transport direction while rotating the crop, and polishes the crop.

The roller portion 4 is provided with a plurality of protruding pieces 5 made of a rubber material (elastic material) having flexibility enough to be deformed by contact with agricultural products over the entire peripheral surface.
Further, the convex piece 5 is formed on the surface of a sheet-like body 51 formed in a rectangular shape having an area that can be wound around the entire circumference of the roller portion 4 using the same rubber material as the convex piece. The sheet-like body 51 is wound around the roller portion 4 and fixed by a well-known fixing means (not shown) such as an adhesive or a concave-convex engagement. A piece 5 projects from the peripheral surface of the roller portion 4.
In addition, when the projecting piece 5 cannot be expected to have a desired effect due to wear or the like, the sheet-like body 51 can be peeled off from the roller portion 4 and replaced with a new sheet-like body.

That is, since the convex piece 5 can be exchanged by exchanging the sheet-like body 51, when the convex piece 5 is worn or the like, it is not necessary to replace the entire roller portion 4 or to remove the roller portion 4. Since it can be performed, maintenance can be performed easily and inexpensively.
For example, since the roller part is connected to the rotation transmission mechanism, when the entire roller part is replaced, the rotation transmission mechanism is disassembled, removed from the frame, a new roller part is attached to the frame, and the rotation is performed. Although the troublesome work of assembling the transmission mechanism is required, such troublesome work is unnecessary if the sheet-like body is replaced as described above.
Further, since the sheet-like body, which is a molded product of rubber material, is naturally cheaper than the roller portion, it can contribute to cost reduction as a replacement part.

Here, the configuration of the convex piece 5 of this embodiment will be described in detail. The convex piece 5 is formed in a small-diameter cylindrical shape having a spherical tip, and the convex piece 5 is formed along each side of the sheet-like body 51. The projections 5 are arranged so as to protrude between the convex pieces 5 with an interval corresponding to one convex piece 5.
Further, the convex piece 5 is projected so as to be orthogonal to the plane of the sheet-like body 51, and when the sheet-like body 51 is wound around and fixed to the roller portion 4 supported in an inclined manner as described above. In addition, all the convex pieces 5 are inclined in the transport direction.
That is, with the rotation of the roller portion, the force of conveying the crop and the force of rotating the crop can be applied to the crop by the tilt of the roller 4 and the tilt and elasticity of the convex piece 5.

According to the second cleaning unit B of the present embodiment, the crop transferred from the first cleaning unit A is placed on the roller unit 4 with its line direction intersecting the transport direction, but the crop is inclined. By rotating the roller unit 4, the linear direction is made to follow the conveying direction, and the valley unit 41 is moved.
Moreover, since the shock of the fall at the time of the transfer from the 1st washing | cleaning part A is buffered by the elasticity of the convex piece 5, the damage of the crop at the time of the transfer can be prevented.
Further, the convex piece 5 is bent by the weight of the crop moved to the valley 41 and is in a state of supporting the crop on the peripheral surface of the convex piece 5, so that the convex piece 5 is rotated with the rotation of the roller portion 4. It becomes operation | movement which polishes the surrounding surface of the crop supported by the valley part 41 by the surrounding surface.
And with rotation of the roller part 4, while the crop part rotates in the trough part 41 with the force to the conveyance direction which arises with the inclination of the roller part 4, and the inclination and elasticity of the convex piece 5, and the force which rotates a crop, Polishing and rooting can be carried out by polishing the crop supported by the valley 41 on the peripheral surface of the convex piece 5 during this operation.
At the same time as the transporting operation and the polishing operation, the crop is washed with the washing water sprayed from the nozzle portion N2.

Moreover, the convex piece 5 of this embodiment is provided so as to be inclined with respect to the surface of the sheet-like body 51, and when the sheet-like body 51 is wound and fixed to the roller portion 4, the convex piece 5 is inclined. By directing the direction to the transport direction, a force in the transport direction caused by the inclination and elasticity of the convex piece 5 and a force to rotate can be applied to the crop as the roller unit 4 rotates. .
Further, during the operation in which the agricultural product is conveyed downstream while rotating in the valley 41, polishing and rooting are performed by polishing the agricultural product supported by the valley 41 on the peripheral surface of the convex piece 5. Can do.
