本発明は、水田とくに重粘土壌の水田を畑圃場に転換す

It is.
［従来の技術］

。[Conventional technology] In recent years, paddy fields have been converted to upland fields to adjust rice production, but upland crops, unlike paddy rice, are severely damaged by flooding, so converted upland fields have to drain surface water. By the way, in paddy fields, especially those with heavy clay soil, the subsoil becomes compacted due to treading and plowing with large machines, and soil physical properties such as aeration, water permeability, and water retention become poor. In addition, due to rotary plowing, which is repeated every year, the cultivated soil is shallow, and a plow layer that is difficult to permeate is formed below it.Even if there is a culvert, if there is a large amount of rainfall, stagnant water will occur on the surface of the ground, causing the soil to grow. If the layer becomes overly humid and there is no rainfall for a long period of time, the tiller will be unable to absorb moisture from the lower layer of the cultivated soil, causing the cultivated soil to become dry and often cause drought damage.

にすることが必要である。Therefore, when converting a paddy field into an upland field as described above, the plow layer, which has poor water permeability and water retention, is destroyed, and the subsoil is expanded to improve the air permeability and water permeability of the soil. Improve soil quality and increase soil layer to 20 to 30 cm, which is desirable for field crops.
It is necessary to do so.

いる。Traditionally, in order to convert paddy fields into upland fields, the subsoil is destroyed with a subsoil crusher and the subsoil is expanded, and then the soil is plowed and turned over with a plow, or the subsoil is plowed with a subsoil plow. A method is used in which the subsoil is expanded and the subsoil is softened by inverting the plowing and plowing plates together. In addition, in order to improve removal of surface water, a trench was installed perpendicularly to the existing culvert to a depth of 50 cm.
A method used is to dig a trench of ~60 cm and manually throw rice husks into the trench to improve the water permeability of the field. In addition, a rice husk filling hopper is attached to the top of the bullet culvert excavator, and by combining it with a blower driven by the PTO of a tractor, the rice husk in the hopper is forcibly blown into the rice husk filling bullet that has passed through the bullet culvert pillar. Underdrain construction machines are also known.
［発明が解決しようとする課題］

ことにより耕盤を破壊できるが、心土破砕機の場合と同
様に破砕された心土の固結が早いという問題点があった
。[Problems to be Solved by the Invention] In the conventional technology described above, the method of crushing the subsoil with a subsoil crusher is that in the case of single-layer clay soil, the pillars are required to crush the subsoil and the cultivated soil at the same time. In addition to the large amount of power required, the subsoil is completely crushed and contains a large amount of water, which causes it to solidify in two to three years under the pressure of tractors, etc., making it ineffective. . In the method of using a subsoil plow, the plow can be destroyed by reversing the plowing of the cultivated soil and the plowing plate together, but as in the case of a subsoil crusher, the compaction of the crushed subsoil is The problem was that it was fast.

チャ−の場合と同様な問題点があった。In addition, the method of digging a trench with a trencher and manually introducing rice husks is expensive and time-consuming, and it is not possible to crush the plow and subsoil other than where the trencher has passed, so it is necessary to crush the plow and subsoil separately. The problem was that it was necessary. The rice husk-filled bullet culvert construction machine can save cost and labor in forming rice husk culverts compared to the above-mentioned trencher, but it cannot crush the plow and subsoil other than the area where the pillars pass, so it is not suitable for trenchers. There were similar problems.

The purpose of this invention is to provide an improved tillage method and a working machine that can perform the method continuously at once.

する。As shown in Fig. 8, a typical longitudinal section of a paddy field with heavy clay soil consists of plowing soil A, plowing plate B below it, and hard subsoil C below it. In this paddy field, when the work machine is advanced as described above, the front of the double core soil tilling plow (hereinafter abbreviated as plow) is connected to the plowing soil A as shown in Figure 9. The plowing platform B is turned over, the gravel is moved to the right, and the subsoil C is exposed. Then, the front apse type subsoil does not follow the front plow, and forms a subsoil crushed portion C1 in the exposed subsoil C with a width narrower than the plowing width of the plow.

けられている中空り柱は、前記の溝内を前進する。The rear plow does not move forward on the left rear side of the front plow, but as shown in Figure 10, the front plow plows the left side to the same plowing width as the front plow and plows the gravel. Move to the right side, cover the subsoil C where the fractured portion C1 is formed, and expose the subsoil on the bottom surface of the gravel. Continuing on, the rear apse-type core soil plows up the exposed core soil of the front plow to a width narrower than the plowing width of the plow, forming furrow E that reaches the culvert. The hollow column, which is attached to the rear end of the frame of the working machine in a hanging manner, moves forward within the groove.

れる状態を矢印で模式的に示している。On the other hand, the rice husk tank supplies pre-filled rice husks to the blower 9 via a rice husk passage cylinder using a transverse conveyor provided at the bottom of the box section. The blower 9 forces the supplied rice husks to pass through the hollow part of the hollow column and forcefully blows them into the grooves E. FIG. 11 schematically shows the state in which the rice husks F are thrown in using arrows.

起し、心土に破砕部と籾殻が投入された溝を形成する。As described above, when the work equipment reaches the other edge of the rice field, lift the work equipment, turn to the left, proceed an appropriate distance, lower the work equipment to the edge, and remove the existing equipment. Proceed perpendicular to the culvert. Then, the working machine plows the cultivated soil and the plowing platform, and forms a groove in the subsoil into which the crushed portion and the rice husks are thrown.

入する。Then, the plow in front of the plow turns over the cultivated soil and plowing platform,
As shown in Figure 12, the subsoil in which the groove El into which rice husks have already been input (hereinafter referred to as the rice husk input groove) is covered with gravel, and the apse-type subsoil in the front is placed in the subsoil. A subsoil fractured part c1 is formed in the part. Subsequently, the rear plow plows and reverses the uncultivated area on the left that was plowed by the front plow again, as shown in Figure 10, and shingles the subsoil where the subsoil crushing area cl has been formed. At the same time, the subsoil is newly exposed, and the trailing type subsoil behind the subsoil forms the groove E.
Then, the blow 9 passes through the hollow column and throws in the rice husks in the same manner as described above.
なお、第９図〜第１２図は、既設の暗渠を省略している
が、前記の籾殻投入溝Ｅｌは、後方の後随型心土りの耕

１５図のように、暗渠に直交に接続される。Although the existing culvert is omitted in Figures 9 to 12, the rice husk input groove El is designed so that the plowing depth of the trailing type core soil at the rear reaches the existing culvert. Therefore, as shown in FIG. 15, for example, it is connected orthogonally to the underdrain.

土を覆ったときれき土が溝に入り心土破砕部となる。The back conveyor is rotated by a hydraulic motor and sends the rice husks in the rice husk tank from the front to the rear, and supplies them to the box section. The supply amount is changed by changing the speed of the rotation of the rear conveyor using a hydraulic motor. Furthermore, if the transverse conveyor and the blower are stopped, the rice husks are not thrown into the groove, and when the subsoil is covered with gravel, the cleared soil enters the groove and becomes the subsoil crushing section.

吸い上げが良好な圃場になる。Therefore, since the subsoil is partially crushed, compared to the case where the subsoil is completely crushed, the subsoil does not contain excessive moisture, and even if it is subjected to pressure from tractors etc. during the farming stage, the subsoil does not contain too much water. It is possible to create a field where the soil does not return to a compacted state for a long period of time. Additionally, as is well known, rice husks do not consolidate or rot in the soil for long periods of time, so rice husk input ditches formed in the subsoil can be used to turn paddy fields into fields that maintain a sustainable drainage effect over a long period of time. I can do it. and,
In this field, the tiller beneath the cultivated soil has been destroyed, so
The roots of crops extend well into the subsoil, creating a field where the cultivated soil can absorb moisture well from the lower layer.

In particular, the trailing type subsoil at the rear is one that plows up the subsoil to form a groove, and the hollow pillar into which the rice husks are thrown is made to move forward within the groove, thereby ensuring that the rice husks are properly placed in the core. It can be put into the soil. Furthermore, by arranging a plurality of conveyors in parallel at the inner bottom of the rice husk tank, even if the capacity of the rice husk tank is increased, rice husks can be reliably supplied to the box portion at the rear of the rice husk tank. If the rear conveyor is rotated by a hydraulic motor, the rotation speed of the rear conveyor can be easily changed and the amount of rice husks transported backwards can be changed. Even if the hydraulic motor stops, damage can be avoided.

えて心土を改良することができる。Furthermore, by installing a transverse conveyor horizontally in the box section at the rear of the rice husk tank and installing a blower at the top of the hollow column, rice husks are reliably supplied from the box section to the blower by the transverse conveyor, and the bulk specific gravity is small. Therefore, it is possible to forcibly throw in rice husks, which would be difficult to densely fill into the grooves of the subsoil by falling naturally. Therefore, the rice husk input groove is densely filled with rice husks and hardly deforms even when subjected to pressure from a tractor or the like. Since the lateral conveyor and blower are rotated by the PTO of the towing tractor, by stopping the PTO, the row spacing of the rice husk input groove can be easily changed, and by changing the rotation of the PTO, the amount of rice husk input can be changed. be able to. Furthermore, by making it possible to adjust the plowing depth of the trailing type subsoil, the depth of the subsoil crushing part and the rice husk input groove can be changed.
The subsoil can be improved by changing the construction conditions for various rice fields with different soil conditions.
