Description

TECHNICAL FIELD The present invention relates to an agricultural work machine for fertilizing additional fertilizer and soiling ridges to the side.

2. Description of the Related Art Conventionally, in the process of cultivating a crop, the ridges are cultivated according to the degree of growth of the crop, and soil cultivating work is performed by a soil gathering and shaping device.

In addition, additional fertilizer is applied according to the degree of growth of crops.

Here, when fertilizing the additional fertilizer, it is necessary to take care so that the fertilizer does not directly contact the crop, and it is common for the worker to manually fertilize the side of the ridge.

In addition, if the ridges are covered with multi-film,
An operator manually pulls up the side edge of the multi-film, and then applies fertilizer with additional fertilizer and soils.

Problems to be Solved by the Invention First, manual fertilization of additional fertilizer is apt to vary because the amount of fertilizer applied is proportional, and there are places where the amount of fertilizer is insufficient or excessive.

In addition, a backpack-type fertilizer applicator is also used for this fertilizer application, but a fertilizer applicator that stores a large amount of fertilizer is a heavy load, and further, the worker walks in the ditch between the ridges with poor footing. Because of this, it is extremely hard work. Even when using a backpack-type fertilizer applicator, the fertilizer application location is determined manually, and the fertilizer is often applied to the crop. It has a bad influence.

In addition, the fertilizer applied to the side of the ridge is likely to fall naturally into the groove between the ridges due to the side slope of the ridge, and a sufficient fertilizing effect may not be obtained.

If the ridge is covered with multi-film,
In order to apply fertilizer with additional fertilizer and soil dirt, it is time-consuming and time-consuming because the multi-film is pulled up and supported in advance and then fertilization work is performed, and the multi-film is pulled down after the fertilization work is completed.

INDUSTRIAL APPLICABILITY The present invention can prevent additional waste fertilizer from falling into the groove between the ridges and waste it, and can perform soil cultivating work according to the degree of growth of the crop while obtaining an effective fertilization effect on the growing crop. The purpose is to obtain the agricultural working machine.

Means for Solving the Problems A soil gathering rotor for soil gathering on the side of the ridge and a soil gathering shaper for pushing the soiled soil against the side of the ridge are connected to a mobile agricultural machine, and immediately before the soil gathering by the soil gathering rotor. A fertilizer applicator for fertilizing fertilizer near the root of a growing crop and near the top edge of soil to be earthed, a fertilizer application location by the fertilizer applicator, and an earth close by the earth-applying rotor and the earth-applying shaper. A multi-film support for lifting the multi-film covering the ridge at a location is connected to the mobile agricultural machine.

Action Fertilization by the fertilizer applicator is performed near the root of the growing crop just before the soil is gathered by the soil gathering rotor and near the top edge of the soil to be soiled, so soil is deposited before it falls into the groove between the ridges. The soil is covered by the rotor, which makes it possible to effectively use the fertilizer, and the soil that has been soiled by the soil gathering rotor and covered with the fertilizer is pressed against the side of the ridge by the soil gathering shaper, and fertilization of additional fertilizer is applied. The work and the soil-applying work are performed at the same time, and the fertilizer-applying work and the soil-applying work can be performed without lifting the multi-film in which the multi-film support covers the ridges and separately lifting the multi-film.
