Description

  TECHNICAL FIELD The present invention relates to an agrochemical spraying hovercraft that has improved shore separation properties in a pesticide spraying hovercraft that is suitable for spraying agricultural chemicals on paddy fields by remote control.

Even in agricultural areas where agricultural land has conventionally been integrally formed, in recent years, there has been an increase in housing land, and so-called urban mixed farmland where farmland and residential land are mixedly mixed is increasing. However, even in these urban mixed farmlands, paddy fields are formed and rice cultivation is carried out as usual. On the other hand, in paddy rice cultivation, agricultural chemical spraying is carried out from the viewpoint of weed weeding. Here, in the above weed weeding, it is known to be effective at an early stage after transplanting seedlings to paddy fields, and the herbicide used at this time is called paddy field initial herbicides. It is.
By the way, spraying methods for pesticides such as the above herbicides include spraying with the same principle as spraying, mist spraying with fine airflow using high-speed air current, and large and powerful fan. There is a large blower sprayer for rice fields (super spouter / sprayer). Also, in recent years, due to the aging problem of agricultural workers and the shortage of labor, it has become necessary to improve the efficiency of spraying agricultural chemicals, and the most efficient spraying method has been implemented everywhere. . In addition, there are methods such as manned helicopter and unmanned helicopter by remote control for the above-mentioned aerial spraying, and these methods have the advantage of promoting the efficiency of spraying agricultural chemicals, but a certain amount of regional unity is required. There was also a limit. Furthermore, the above-mentioned aerial spraying was effective in March 2003, as it was difficult to use in areas where there were fields such as mixed crops and special cultivation fields, urban mixed farmlands, and organic farming. The revised Agricultural Chemicals Control Law and the Ministry of Agriculture, Forestry and Fisheries / Ministry of the Environment newly require proper use at the user level.
Here, among the above-mentioned methods for spraying agricultural chemicals, aerial spraying is considered to be the most effective method. However, in the embodiment of remotely operated unmanned helicopter, since the amount of agricultural chemicals that can be loaded at a time is limited, It was also observed that a high concentration of pesticides different from the dilution factor was being sprayed. Against this background, today's aerial spraying has become stricter due to the revised Agricultural Chemicals Control Law and the necessity of proper use at the user stage. On the other hand, according to the revised Agricultural Chemicals Control Law, even for registered pesticides, depending on the type of product, the production of agricultural products is judged to be out of the standard due to the scattering of agricultural chemicals. Problems have also arisen.
In view of the above background, instead of spraying in the air, there has been a need for a new spraying method capable of carrying out efficient agricultural chemical spraying without scattering of drugs.

In response to such a situation, Japanese Patent Laid-Open No. 9-233985 “Hovercraft for paddy field and its agrochemical spraying method” has been proposed as a response to the above request. Here, when the outline of the invention is shown, the invention relates to a hovercraft for paddy fields that travels on the surface of water and sprays chemicals as a means of mechanization of spraying work such as agricultural chemicals and fertilizers. One gist is a hovercraft for paddy fields that is equipped with a tank for agrochemicals such as granule, granule wettable powder, and liquid agent and a spraying device for spraying the pesticide on the hovercraft body so that traveling and spraying can be remotely controlled. Met. Further, the paddy hovercraft can be provided with a light source at the main contour portion of the paddy hovercraft main body. Further, the paddy hovercraft may be capable of traveling control by the balance of the floating airflow. Further subsequently, the paddy hovercraft is the paddy hovercraft described above, characterized in that the pesticide may be mounted, run on the paddy field by remote control, and spray the pesticide during that time. It was also a thing.
Next, as an improvement in the operability of the “Hovercraft for paddy fields” according to the above-mentioned JP-A-9-233985, JP2007-151481 “Hovercraft for spraying agricultural chemicals” according to the application of the present patent applicant has been proposed. Yes. Here, the outline of the invention is configured at the rear part of the hovercraft body so that the paddy hovercraft can be accurately operated even when the paddy hovercraft is far away from the operator. At the top of the fan duct, a CCD camera for projecting the image of the front of the ship onto the monitor on the controller, and an ultra-high sound that generates a warning sound from the speaker on the controller when it senses an approach over a set distance to obstacles such as tunnels and banks. It was characterized by providing a sonic sensor device.
