Extension type equipped with airframe (1), crushing / standing device (2), connecting device (3), grooving device (4), leveling device (5), and straw turning device (6) Shallow-plowing / crushing / standing machine, crushing / standing apparatus (2) includes crushing / standing box (21), crushing / standing box (21) is bottom plate (211), side plate (212) And the top plate (213), the lower bearing base (271) is attached to the bottom plate (211), the rib plate (273) is welded between the lower bearing base (271), and the rib plate (273) and the bottom plate ( 211) Extension type shallow plowing / crushing / standing machine having a lubricating oil passage between the top plate and the upper bearing stand. The extension type tilling / crushing / standing machine can improve the strength of the lower bearing stand. Multiple bearings can be attached to places where a large force is applied, and less bearings are attached to places where a small force is applied. In addition, the cost can be reduced while improving the stability of the transmission, the rib plate is welded, and the smooth flow of the lubricating oil in the crushing / standing box is ensured, thereby improving the lubricating effect.機体（１）と、破砕・畝立装置（２）と、連結装置（３）と、溝掘り装置（４）と、均し装置（５）と、わら返し装置（６）とを備えるエクステンション型浅耕・破砕・畝立機であって、破砕・畝立装置（２）が破砕・畝立箱（２１）を含み、破砕・畝立箱（２１）が底板（２１１）、側板（２１２）と天板（２１３）を含み、底板（２１１）に下軸受台（２７１）が取付けられ、下軸受台（２７１）の間にリブ板（２７３）が溶接され、リブ板（２７３）と底板（２１１）の間に潤滑油通路を有し、天板に上軸受台が取付けられたエクステンション型浅耕・破砕・畝立機。エクステンション型耕作・破砕・畝立機は下軸受台の強度を向上でき、大きい力がかかる箇所に複数の軸受が取付けられ、小さい力がかかる箇所に少ない軸受が取付けられることにより、伝動軸の剛性や伝動の安定性を向上しながらコストを下げることができ、リブ板が溶接され、且つ破砕・畝立箱における潤滑油のスムーズな流れが確保され、潤滑効果が向上する。
