Advantages of the Invention

[0009] As described above, in the invention according to claim 1, the hydroponic planting panel made of foamed synthetic resin with a plurality of planting holes for plants is horizontally conveyed by the above-mentioned conveying mechanism. The upper and lower surfaces of the planting panel during horizontal conveyance are brush-cleaned by the brush cleaning mechanism, and high-pressure cleaning water is sprayed onto the upper and lower surfaces of the planting panel during horizontal conveyance by the injection water cleaning mechanism. Sequentially, the planting panel is fed manually or automatically, and the cleaning of the planting panel will be performed. At this time, the upper and lower conveying rollers of the pair above and below the conveying mechanism sandwich the upper and lower surfaces of the planting panel at the inlet side position and the outlet side position in the conveying direction of the planting panel to horizontally convey the planting panel, and the planting panel can be reliably horizontally conveyed. Furthermore, the upper and lower surfaces of the planting panel can be brush-cleaned at the inlet side position and the outlet side position in the conveying direction of the planting panel by the above-mentioned inlet side cleaning mechanism and outlet side cleaning mechanism, and the upper and lower surfaces of the planting panel can be reliably cleaned. Furthermore, since the injection water cleaning mechanism is disposed at an intermediate position in the above-mentioned conveying direction between the inlet side cleaning mechanism and the outlet side cleaning mechanism, after the upper and lower surfaces of the planting panel are cleaned by the inlet side cleaning mechanism, the upper and lower surfaces of the planting panel are cleaned by the injection of the high-pressure cleaning water of the injection water cleaning mechanism. Then, the upper and lower surfaces of the planting panel can be cleaned by the outlet side cleaning mechanism, and thus, the upper and lower surfaces of the planting panel can be reliably cleaned. Furthermore, since a pressing mechanism capable of pressing the upper conveying roller facing the upper surface of the planting panel against the upper surface of the planting panel is provided, the hydroponic planting panel made of foamed synthetic resin with a plurality of planting holes for plants can be reliably horizontally conveyed, the planting panel can be sequentially and reliably cleaned, and the smoothness of cleaning and the cleaning workability can be improved. , and the above inlet-side cleaning mechanism and outlet-side cleaning mechanism each consist of an upper rotating brush for cleaning the upper surface portion of the above fixed panel and a lower rotating brush for cleaning the bottom surface portion of the above fixed panel. The rotation direction of the upper rotating brush of the inlet-side cleaning mechanism and the rotation direction of the lower rotating brush are set to the same rotation direction as each other, and the rotation direction of the upper rotating brush of the outlet-side cleaning mechanism and the rotation direction of the lower rotating brush are set to the same rotation direction as each other. Therefore, since the above fixed panel is conveyed through the opposing gaps between the upper and lower pairs of upper and lower rotating brushes, the contact rotation direction between the upper surface portion of the above fixed panel and the upper and lower pair of upper rotating brushes and the contact rotation direction between the bottom surface portion of the above fixed panel and the lower rotating brush are opposite rotation directions to each other, and the upper surface portion and bottom surface portion of the above fixed panel can be reliably cleaned by this opposite contact rotation direction.

[0010] Moreover, in the invention according to claim 2, since the pressing mechanism is composed of a spring member capable of pressing the upper conveying roller against the upper surface portion of the fixed panel, variations in the thickness of the fixed panel can be absorbed by the vertical movement of the upper conveying roller. The upper conveying roller moves up and down according to the conveying state such as the meandering of the fixed panel by the upper conveying roller, and the fixed panel can be smoothly horizontally conveyed. Further, in the invention according to claim 3, since the materials of the pair of upper and lower conveying rollers are made of silicon rubber, wear of the fixed panel and defects such as the opening peripheral edge of the planting hole can be suppressed during the conveyance of the fixed panel, and the durability of the fixed panel can be improved. Moreover, in the invention according to claim 4, since the rubber hardness of the silicon rubber is set to 35° to 45°, the frictional contact state between the upper conveying roller and the upper surface portion of the fixed panel and between the lower conveying roller and the bottom surface portion of the fixed panel becomes good, the conveyance of the fixed panel can be smoothed, and wear of the fixed panel and defects such as the opening peripheral edge of the planting hole can be suppressed.

[0011] Moreover, in the invention according to claim 5 , above The rotation direction of the upper rotating brush of the inlet side cleaning mechanism and the rotation direction of the upper rotating brush of the outlet side cleaning mechanism are set to be different from each other, and the rotation direction of the lower rotating brush of the inlet side cleaning mechanism and the rotation direction of the lower rotating brush of the outlet side cleaning mechanism are set to be different from each other. Therefore, the high-pressure cleaning water jetted from the jet water cleaning mechanism onto the upper surface portion and the bottom surface portion of the fixed panel can be surely diffused in the conveying direction and the direction opposite to the conveying direction. By diffusing the high-pressure cleaning water, the cleaning water can be agitated, the cleaning of the fixed panel can be surely performed, and the cleaning workability can be improved. Moreover, in claim 6In the described invention, side brushes for cleaning both side faces of the fixed panel are provided on both sides of the upper rotating brush of the inlet-side cleaning mechanism, and side brushes for cleaning both side faces of the fixed panel are provided on both sides of the lower rotating brush of the outlet-side cleaning mechanism, or side brushes for cleaning both side faces of the fixed panel are provided on both sides of the lower rotating brush of the inlet-side cleaning mechanism, and side brushes for cleaning both side faces of the fixed panel are provided on both sides of the upper rotating brush of the outlet-side cleaning mechanism. Therefore, both side faces of the fixed panel can be cleaned by the side brushes of the upper rotating brush of the inlet-side cleaning mechanism, and both side faces of the fixed panel can be cleaned by the side brushes of the lower rotating brush of the outlet-side cleaning mechanism, or both side faces of the fixed panel can be cleaned by the side brushes of the lower rotating brush of the inlet-side cleaning mechanism, and both side faces of the fixed panel can be cleaned by the side brushes of the upper rotating brush of the outlet-side cleaning mechanism, and both side faces of the fixed panel can be cleaned well.

[0012] Also, in the claim 7 In the described invention, a plurality of injection nozzles for injecting high-pressure cleaning water onto the upper and lower faces of the fixed panel during horizontal conveyance are arranged in the injection water cleaning mechanism, and a pressure pump capable of supplying high-pressure cleaning water to the injection nozzles is connected. Therefore, the cleaning workability of the fixed panel can be improved, and the structure of the injection water cleaning mechanism can be simplified. Also, in the claim 8 In the described invention, a recovery gutter for recovering the cleaning water is arranged at a position below the injection water cleaning mechanism. Therefore, the cleaning water after the cleaning operation can be recovered and reused for the cleaning operation of a new fixed panel, the cleaning water can be used repeatedly, the cleaning water can be effectively utilized, the cleaning work location is not restricted, and flexibility in use can be achieved.

Further, since the injection water washing mechanism W is disposed at an intermediate position in the conveying direction T between the inlet side cleaning mechanism I and the outlet side cleaning mechanism D, after the upper surface portion P and the bottom surface portion P of the planting panel P are cleaned by the inlet side cleaning mechanism I, the high-pressure washing water W of the injection water washing mechanism W is injected to clean the upper surface portion P and the bottom surface portion P of the planting panel P.
