Japanese Utility Model Publication No. 4-48844

As described above, labor saving has been achieved for the spraying of the control agent and the herbicide by the large boom sprayer and the riding management machine 70. However, with regard to irrigation that should be performed after sowing, after planting, and after transplanting in crop cultivation, efficient irrigation work cannot be performed even if the boom sprayer or the riding management machine 70 is owned, and sufficient labor saving is achieved. It was not planned.
The first reason is that a large amount of water must be irrigated after sowing, after planting, and after transplanting, while the existing boom sprayer and the riding management machine 70 are operated at extremely low speed (0.3 m). Even if it is used for irrigation at about / sec) to secure the water discharge amount, the amount of water discharged in a mist form from each of the spray nozzles 80 is extremely small (about 1 liter / min). Therefore, the amount of water sprayed on the location to be irrigated is significantly insufficient with respect to the required water amount (about 10 liters / min). The second reason is that when the existing boom sprayer or the riding management machine 70 is run at an extremely low speed (about 0.3 m / min), a large amount of water is sprayed not only in the ridges but also in the ridges. Therefore, when the wheel 76 travels in such a gap, the field becomes rough. In addition, it is inefficient to cause the riding management machine 70 to travel at an extremely low speed as described above. The third reason is that a large amount of water will be sprayed on the spaces between the intercostals and ridges that do not need to be irrigated, especially when the riding management machine 70 is used. This means that the liquid tank 84 must be replenished with water several times before the irrigation work for the entire field is completed.

  For these reasons, even if the existing boom sprayer and the riding management machine 70 are owned, they cannot be used for irrigation work as they are. As a result, in most cases, the irrigation work was carried out by hand-spraying work such as set moving jets.
