PROBLEM TO BE SOLVED: To provide a farm-working crawler-type dolly which exhibits functionality even on a bad road, a steep slant face, and in a narrow site, and is excellent in operability and safety, and to perform chemical spray work by using the dolly by solving a problem that, in agricultural work on a steep slant face of a mountainous area such as an orchard, the work is heavy, and a farm-working machine for assisting the work should be small in size and light in weight, and should have functionality, that a machine using a conventional engine is complicated in operation, and lacks in safety, and that the spray work of agricultural chemicals is heavy in a burden, and may cause a risk that a farmer sucks a harmful gas.SOLUTION: Operation easiness and the quality of a work environment are improved by employing motors as drive sources, a fine movement becomes possible by independently controlling movements of left and right crawlers by the two motors, and functionality is secured by narrowing a turning range as much as possible and so forth. Furthermore, by electronically controlling drive wheels and a chemical supply pump, a wireless or wired remote operation becomes possible, a burden on work is alleviated, and safety is enhanced.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】果樹園など山間地の急斜面での農作業は重労働でそれを補助する農業機械は小型、軽量であって機動性を有することが要求される。従来のエンジンを採用した機械は操作が複雑で安全性に欠ける。また、農薬等の散布作業は負担が重くかつ有害な気体を吸引するおそれがある。そこで、悪路、急斜面、狭小地であっても機動性を発揮し、操作性、安全性に優れた農作業用クローラ式運搬車を提供し、これを利用した薬液噴霧作業も可能にすることを目的とする。【解決手段】駆動源にモータを採用して操作容易性、作業環境の質の向上を図り、2つのモータにより左右のクローラの動きを個別に制御することで細かな動きを可能とし、旋回範囲を可及的に小さくするなど機動性を確保する。また、駆動輪や薬液供給ポンプを電子制御し、無線或いは有線による遠隔操作を可能にして作業の負担軽減及び安全性を高める。【選択図】図1
