[0002]

2. Description of the Related Art Agricultural machines have been put into practical use in various ways according to the properties of target agricultural products. For example, Japanese Patent Laid-Open No. 61-141805 proposes a compost spreader. A compost spray tank is placed on a walk-type cultivator, and a conveyor, stirring beater,
With a built-in scraping beater, an appropriate amount of compost can be dropped and sprayed from the compost spray tank. The compost spreader can be manufactured at low cost because the compost spreader is simply placed on the walkable tiller that is easily available.

[0003]

However, in the case of leaf tobacco cultivation, it is necessary to spray compost, apply fertilizer with chemical fertilizer, disinfect soil, cultivate, ridge, and hang vinyl. After the compost is sprayed by the compost sprayer, the chemical fertilizer sprayer, the soil disinfecting machine, the tiller, the ridger, and the vinyl hanging machine are used to perform the respective operations. Generally, a small tractor is replaced with various work machines for work, but the next work cannot be started until one work is completed. It takes a few days for each work, and if a rain break occurs in the middle of work, it is not uncommon to require 30 days to complete all the work. In this case, the work efficiency is too low and the work plan cannot be planned, which puts a heavy burden on the worker. Therefore, an object of the present invention is to provide an agricultural work machine capable of advancing work at once in fine weather.

[0004]

In order to achieve the above object, the present invention has a crawler type traveling carriage equipped with a composting hopper, a chemical fertilizer hopper and a chemical solution tank, and a chemical solution nozzle for dropping a disinfectant to cultivated soil at the rear part of the cart. An agricultural working machine is configured by connecting a cultivating rotor for cultivating cultivated soil, a ridge standing guide plate for cultivating cultivated cultivated soil, and a vinyl sheet feeding mechanism for hanging a vinyl sheet on the ridge.

[0005]

[Function] The six work steps of "compost spraying", "chemical fertilizer spraying", "chemical solution spraying", "cultivation", "row raising", and "vinyl hanging" are carried out in one run.
