Description

  This device relates to an apparatus for controlling irrigation to a cultivation container used when growing young seedlings such as vegetables.

In order to irrigate the cultivation container, manual irrigation is common (Patent Document 1). Also, mechanical irrigation is known (Patent Document 2). Furthermore, an irrigation control device is also known in which an excess liquid cocoon coming out of the cultivation container is applied to the inclined conductive wire, the sensor device is operated by the cocoon flowing down along the inclined conductive wire, and irrigation is stopped. However, due to the salts in the waste liquid mixed in the irrigation liquid, the sensor provided on the conductive wire may malfunction and become unusable.

Utility Model Registration No. 3168859 JP-A-2015-89353

  It is intended to provide an irrigation control device that is not damaged by the fertilizer in the waste liquid that has passed through the cultivation container.

  This will be described with reference to the drawings. The irrigation control device for the group of cultivation containers 12... 12 according to the present invention passes the horizontal member 23 into the horizontal support frame 22 in which the group of cultivation containers 12. The opposed inner surface 54 of the hanging peripheral cylinder 51 that surrounds the upper funnel portion 52 and the lower outlet 53 of the funnel portion 52 below the one cultivation vessel 12a in the group of cultivation vessels 12... 55, a sensor device 60 comprising a light emitting portion 64 and a light receiving portion 65 is attached. When the light beam between the light emitting portion 64 and the light receiving portion 65 is blocked, a signal 62 output from the sensor device 60 is sent to the stop switch 39 of the irrigation pump 34. When the input is made, the irrigation pump 34 is stopped.

  When the irrigation amount to the cultivation container 12 increases and the liquid drops from the funnel portion 52, the light beam between the light emitting portion 64 and the light receiving portion 65 is blocked. Then, the irrigation pump 34 is stopped by the signal output from the light receiving unit 65 and the water supply pipe 35 is stopped.

1 is an overall schematic front view of the present invention. FIG. 2 is a partially enlarged schematic plan view of FIG. 1. It is a partially expanded front view same as the above. It is an enlarged front view of the principal part same as the above. It is an exploded front view same as the above. It is an enlarged side view of the principal part same as the above. It is an exploded side view same as the above.

A rectangular horizontal support frame 22 is provided on the support column 21. Horizontal members 23, 23 that are parallel to each other in pairs are installed on the horizontal support frame 22. The cultivation container 12 is arranged along the longitudinal direction of the horizontal members 23 and 23. A waste liquid receptacle 24 is provided so as to pass below each cultivation container 12, and the liquid Q in the waste liquid receptacle 24 is guided to the waste liquid tank 33. The liquid in the waste liquid tank 33 is sent to the distribution pipe 36 via the water supply pipe 35 along the horizontal bar 25 at the upper part of the support horizontal frame 22 via the filter 32 and the irrigation pump 34. The liquid Q is sent to each cultivation container 12 through a liquid amount adjustment valve 37 at the tip of the distribution pipe 36.

In summary, this device is a group of two horizontal members 23, 23 passed between the horizontal members 23, 23 in the support horizontal frame 22 in which the cultivation containers 12. The light emitting part 64 and the light receiving part 65 are arranged on the opposite inner surface sandwiching the upper funnel part 52 and the lower outlet 53 of the funnel part 52 below one of the cultivation containers 12a in the cultivation container 12. When the sensor device 60 is installed and the light beam between the light emitting unit 64 and the light receiving unit 65 is blocked, the signal 62 output from the sensor device 60 is input to the stop switch 39 of the irrigation pump 34 via the circuit 66. It will stop.

  The soil 42 in the cultivation container 12 in which the seedlings 41 are planted is supplied with irrigation through the distribution pipe 36. Usually, water is irrigated to the extent that no water droplets are dropped from the drain outlet 13 at the bottom. When the water supply or rain becomes supercharged and water drops fall from the drain outlet 13 and the lower outlet 53, the light receiving section 65 catches and stops the irrigation pump 34 via the circuit 66, and stops water supply from the distribution pipe 36. Therefore, leakage of nutrients in the soil 42 can be prevented.
