Description

[Detailed explanation of the idea] (b) Industrial application fields This invention relates to a millet root cutting device.

(b) Conventional technology In the past, in the cultivation of sugar cane, after harvesting, the old roots of the plants left on the surface of the ridge were cut off, and the soil around these roots was temporarily dumped into the grooves between the ridges. Fertilizer is applied into the grooves formed in the ridges, and soil is again applied to the left and right sides of the ridges to encourage new rooting and germination from the remaining plants, in order to increase yields. In addition, for root cutting work, the Utsuka 55
-41044 and Utility Model Publication No. 43-428.
-No. 154903, No. 119202, No. 119202, No. 119202, No. 119202, No. 60-
There were some that were disclosed in No. 131101, etc.

(c) Problems that the invention aims to solve However, the above-mentioned inventions for root cutting work are aimed at extracting or crushing the stumps, and cannot encourage new rooting and germination from the remaining stumps. If it is unsuitable and is intended for earth-filling work, only earth removal or earth-filling work is possible;
All of these machines are single-function machines that perform only root cutting work, soil removal, and earth filling work, and they have the disadvantage of requiring two types of work equipment.

(d) Means to solve the problem In this invention, a horizontal shaft case is connected to the left and right sides of the gear case connected to the machine, and a vertical shaft case is connected to the outer edge of the horizontal shaft case. The plow is installed vertically so that it can freely rotate around its core, and a power transmission mechanism is built into each case to transmit the power from the machine to the plow shaft that projects approximately horizontally from the bottom end of the vertical shaft case. In addition, a disc plow is connected to the outer end of the plow shaft, and the protruding direction of the plow shaft is changed and fixed to at least two directions, inside and outside, at the connecting part between the horizontal shaft case and the vertical shaft case. It is an object of the present invention to provide a millet root cutting device provided with a tightening tool.

(E) Function/Effect According to this invention, during root cutting work, the plant is positioned between the left and right disc plows with the protruding direction of the plow shaft on the inside and the soil discharge direction of the disc plow on the outside, and the plant is run on the top of the ridge. By cutting the old roots on the left and right sides of the plant and simultaneously removing the soil from this area, a groove can be formed in the area where the soil was removed.

After applying fertilizer into the furrow, the vertical shaft case is rotated and reversed so that the protruding direction of the plow shaft runs outward and runs on the top of the ridge, thereby backfilling the fertilized furrow and at the same time bringing soil to the left and right sides of the ridge. It is something that can be done.

Therefore, according to the present invention, root cutting work, earth removal work, and earth filling work can be performed with one work machine, and moreover, the two operations of root cutting and earth removal can be performed in one process. There is something that is done in

In addition, the connecting parts between the horizontal shaft case and the vertical shaft case, which are connected to the left and right sides of the gear case of this machine, are equipped with fasteners that change and fix the protruding direction of the plow shaft at least in two directions: inside and outside. Therefore, it is easy to change and fix the mounting direction of the vertical shaft case and the plow shaft, and the work can be carried out efficiently.
