この発明は暗渠を形成するために、溝を掘削するための
スクリュートレンチャ−の排土装置の改良に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a screw trencher earth removal device for excavating a trench to form an underdrain.
従来の排土装置は掘削の際、螺旋体の左右方向の一方に
排土する構造であるため、第１図に示したように掘削さ
れた溝１の一方の側に大きな土塊２が積上げられて排土
され、溝１底にコルゲート管３を敷設して籾殻４などを
充填したうえ、この土塊２を溝１内に埋め戻すとき、上
部がりのテーパー状断面のこの溝１の底部には、この大
きな土塊２が落人し難く、中間に空洞を生じてしまうこ
とがあり、特に粘土質の土壌においては土塊２が太きい
ため、この傾向も大きくなり勝ちであった。When excavating, conventional earth removal equipment has a structure that removes earth to one side of the spiral body in the left and right direction, so as shown in Fig. 1, large earth clods 2 are piled up on one side of the excavated trench 1. When the soil is removed, a corrugated pipe 3 is laid at the bottom of the trench 1, and rice husks 4 are filled, and the soil mass 2 is backfilled into the trench 1, the bottom of the trench 1, which has a tapered cross section with an upward slope, is This large clod 2 is difficult to fall into, and a cavity may be created in the middle. Especially in clayey soil, where the clod 2 is thick, this tendency tends to increase.
そこでこの発明は、従来の排土装置におけるかかる問題
点を解消するために、第２図に示したように掘削された
溝１の左右に排土を行い、しかも、この排土量は左右を
互いに大小に異ならしめることにより、例えは右側を少
く、左側が多くなるようにこの排土装置を構成したもの
であって、この結果右側は小さい土塊５に、又、左側は
やや大きい土塊６となるため、埋め戻す際には、小さい
土塊５をまず溝１に投入した後、大きい土塊６は溝１の
上部に戻すようにすれば、空洞を生ずること無く、溝１
は埋められることになるものである。Therefore, in order to solve this problem with the conventional earth removal device, the present invention removes earth from both sides of the excavated trench 1 as shown in FIG. By making the sizes different from each other, this soil removal device is configured so that, for example, there is less soil on the right side and more on the left side, and as a result, the right side has a small clod 5, and the left side has a slightly larger clod 6. Therefore, when backfilling, if you first put the small clods 5 into the trench 1 and then return the large clods 6 to the top of the trench 1, you can fill the trench 1 without creating a cavity.

As shown in FIGS. 3 to 5, the drive gear case 7 of the screw trencher has a The upper part of the spiral body 8 is pivotally supported, and the input shaft 10 of the bevel gear mechanism 9 housed internally in the drive gear case 7 is connected to the power take-off shaft of a power agricultural machine (not shown) via a flexible transmission shaft. , is connected to this bevel gear mechanism 9. In the present invention, by attaching a gutter-shaped rear cover 11 to the rear part of a disc-shaped upper end plate 12 formed at the lower part of the drive gear case 7, the spiral body 8 is connected to the bevel gear mechanism 9. The upper part of the rear part in the traveling direction is closed as shown in Figure 6, and
As shown in the figure, a fan-shaped guide portion 1 is provided at the upper end of the gutter-like standing portion 18a.
3b is fixed at right angles to form a front cover mounting piece 13,
This guide part 13 is attached to the front part of the upper end plate 12 of the drive gear case 7.
While stacking the front cover mounting pieces 13, the rotational position of the front cover mounting piece 13 can be freely adjusted around the axis of the spiral body 8 using the mounting bolts 14°14 inserted through the arc-shaped elongated holes 13C and 13C provided in the guide portion 13b. Attach to the upper end plate 12.

5 parallel to the spiral body 8, fix the upper part of this mounting rod 15 to the outer periphery of the guide part 13b of the front cover mounting piece 13, and align the upper part to the outer periphery of the standing part 13a of the front cover mounting piece 13. The mounting bolts 17 of the bracket N6a that fixed the gutter-shaped front cover 16 to the front cover 16
is screwed into the mounting screw fL15a of the mounting rod 15 (this makes it possible to freely adjust the vertical position with respect to the front cover mounting piece 13, and thereby the front cover mounting piece 13 and the front cover 1
6, the cover position in front of the spiral body 8 moving forward in the direction of arrow C can be adjusted both in the left and right direction of movement and in the height direction.

... is fixed to the upper end plate 12 by external force on the outer periphery of the rear cover 11, and as shown in FIG. 19
By screwing the mounting bolts 20 of the bracket 19C into the mounting screw holes 18 while inserting the screws between the rear cover 11 and the mounting rod 18, the rear cover 11 and this earth removal guide plate 19 are moved in the direction of the arrow C. The height of the cover behind the advancing spiral body 8 can be adjusted to be large or small.

The left and right outer edges of the soil discharge guide plate 19 form the left and right soil discharge ports 21.
．． 22 is formed, and the front cover mounting piece 13 and the front cover 16 rotate and adjust the opening lengths of the soil discharge ports 21 and 22 along the outer side of the spiral body 8 along the elongated hole 13C. For example, the opening length of the soil discharge port 21 on the left side is made larger, and that of the soil discharge port 22 on the right side is made smaller.

いものであり、埋め戻し作業においても容易となる。Since the earth removal device according to the present invention is configured as described above, the lower edges of the front cover 16 and the earth removal guide plate 19 can be slid into contact with the ground surface depending on the depth of the trench 1 to be excavated. Adjust these mounting heights, and rotate the front cover mounting piece 13 and front cover 16 along the elongated hole 13C of the upper end plate 12, so that the soil discharge port 21 on the left side becomes the soil discharge port 22 on the right side. By fixing the guide part 13b to the upper end plate 12 at a position where the opening is larger than that shown in FIG. A slightly larger clod 6 will be discharged from the soil discharge port 21, and a smaller clod 5 will be discharged to the right side of the groove 1, and as mentioned above, the small clod 5 will be thrown into the groove 1 first. However, if a large lump of soil 6 is then poured into the upper part of the trench 1, it can be firmly backfilled without leaving any cavities in the trench 1, and there will be no abnormalities in the subsequent planting of crops. There is no risk of this occurring, and the backfilling work will be easier.
又、このように溝１の左右に夫々、振分けて排土できる
ため、埋め戻すまでの間に溝１内に自然に崩落すること
も無いなどこの発明に係る排土装置は暗渠形成作業上多
くの優れた効果を奏するものである。In addition, since the earth can be distributed and discharged to the left and right sides of the trench 1 in this way, there is no possibility that the earth will naturally collapse into the trench 1 until it is backfilled. It has excellent effects.
