本考案は、掘削ドラムと埋戻し体とを取換える
だけで溝掘機と埋戻し機に容易に変更できる対地
作業機に関する。[Detailed Description of the Invention] The present invention relates to a ground working machine that can be easily changed into a trench excavator and a backfilling machine by simply replacing the excavation drum and backfilling body.
通常、例えば施肥溝、植付け溝等を掘つた場
合、施肥、植付けの後にその溝を埋戻す必要があ
るが、従来のアツパカツト式溝掘機は溝掘作業だ
けで埋戻しに利用することはなく、ラセン式覆土
機（埋戻し機）を使つて埋戻している。 Normally, when digging a fertilization trench, planting trench, etc., it is necessary to backfill the trench after fertilizing and planting, but conventional Atsupakatsu trench excavators are only used for trench digging and are not used for backfilling. , backfilling is done using a spiral type soil covering machine (backfilling machine).
そのために、溝掘機と埋戻し機とが必要となる
が、これらは機体及び駆動系が略同一であり作業
体のみの形状が異なるものであり、両機を夫々専
用機とすることは、設備費を非常に高くすること
になる。 For this purpose, a trench digging machine and a backfilling machine are required, but these machines have almost the same machine body and drive system, and only the shape of the working body differs. This will make the cost very high.
この問題を解決するには、１組の駆動系を有す
る機体に作業体となる掘削ドラム及び埋戻し体を
取換自在に取付ければ良いのであるが、そのよう
に構成すれば、掘削ドラムによる掘り残しが多く
なつたり、ラセン軸を有する埋戻し体の取付けの
困難性及び多量の土の寄せ集めの困難性等の問題
が発生する。 In order to solve this problem, it would be possible to attach the excavation drum and backfilling body, which are the working bodies, to a machine body that has one set of drive systems, so that they can be replaced. Problems arise, such as a large amount of leftover soil, difficulty in installing a backfill body having a helical shaft, and difficulty in collecting a large amount of soil.
ところで、このような問題の多くは作業体を取

ある程度解消できるが、駆動軸に自在継手を介し

するほうが、軸長が長くならず、欠点も少なく、
しかもその欠点は容易に解消し得るものであり、
極めて有益であることが、鋭意研究の結果、判明
した。 By the way, many of these problems can be solved to some extent by tilting the shaft on which the work body is attached outward and downward, but if the tilting shaft is connected to the drive shaft via a universal joint, the shaft length will become longer. Other negative effects occur, such as the need to increase the diameter of the excavation drum, difficulty in backfilling the center of the trench, and an increase in the size of the equipment. Therefore, it is better to fit a cylindrical inclined shaft to the drive shaft so that it can rotate integrally, since the shaft length will not be long and there will be fewer drawbacks.
Moreover, these shortcomings can be easily overcome,
As a result of intensive research, it has been found that it is extremely beneficial.
本考案は、このような種々の点に鑑み、駆動軸

易化及びより多くの土の寄せ集めを可能にすると
共に、埋戻し体取付時における駆動軸と傾斜軸と
の間への土侵入を防止するようにした対地作業機
を提供することを目的とする。 In view of these various points, the present invention uses an inclined shaft fitted to the drive shaft to make the excavation drum and backfill body replaceable, and at the same time reduces the amount of unexcavation left by the excavation drum. , a ground work machine that facilitates the installation of the backfill body, enables the collection of more soil, and prevents soil from entering between the drive shaft and the inclined shaft when installing the backfill body. The purpose is to provide.

れている点にある。 A feature of the present invention for achieving this purpose is that a pair of left and right cylindrical inclined shafts with outwardly downwardly inclined shapes are integrally rotatably fitted to the drive shaft protruding left and right from the transmission case. In a ground work machine in which a work body is removably attached to this inclined shaft, an excavation drum for trench digging and a backfilling body for returning soil from outside the trench into the trench can be replaced at flanges provided on each of the inclined shafts. The excavation drum has a large number of excavation claws on its outer peripheral surface, and at least one excavation claw is provided so as to be able to pass under the transmission case, and the backfilling body is attached to the outside of the inclined shaft. A helical shaft is fixed to the outer end of a cap-shaped mounting portion that surrounds the end and is attached to the flange, and is coaxial with the inclined shaft.

なる。 When the cap-shaped mounting portion 51 is fitted to the end of the inclined shaft 14 and the flange 54 is fixed to the flange 19 via the bolt 24, the helical shaft 52 is arranged concentrically with the inclined shaft 14, and the transmission case 6 It rotates with the driving force transmitted from the groove A, and moves the soil on both sides of the groove A toward the groove A. Since the helical shaft 52 is outwardly inclined downward, the work is carried out by lowering the outer end to the extent that it almost touches the ground.If the helical shaft 52 is horizontal, it cannot touch the ground over its entire length, so there is no space between it and the soil surface. A gap is created and a large amount of soil is left behind, but if the trench is tilted as described above, the amount of soil left behind is reduced to approximately half, and the amount of soil far from the trench A is extremely small. Furthermore, the soil collected by the helical shaft 52 moves toward the inclined shaft 14 and tries to enter between it and the drive shaft 13 or come into contact with their ends, but the mounting portion 51 Since the outer end of the oil seal 14 is surrounded, this can be prevented and the oil seal 18 and the like can be protected. Furthermore, when attaching the backfilling body 50 to the inclined shaft 14, the attachment part 51 side can be lifted and diagonally fitted to the inclined shaft 14 while the outer end of the helical shaft 52 is in contact with the ground. There is no need to lift the entire unit, making installation work extremely easy and light.

る。 During backfilling, the lower part 43 of the rear cover 41 is removed, so the lower end of the upper part 44 is suspended in the air. For example, a mulcher 57 as shown in FIG. 7 may be bolted to the lower end of this upper part 44. This earth mulcher 57 consists of a central part 59 which has a notch 58 and is attached to the rear cover 41, and side parts 60, 60 on both sides of which have slopes for mulching. central part 5
At step 9, trench A can be backfilled and filled with earth.

損するのを防止できる。 According to the present invention described in detail above, the excavating drum 7 is attached to the inclined shaft 14 fitted to the drive shaft 13 of the transmission case 6.
Since the backfilling body 50 and the backfilling body 50 can be attached interchangeably, it is possible to perform both trench digging and backfilling using one ground work machine, reducing equipment costs. The total length of the shaft is short, and the distance between the left and right working bodies can be narrowed, and when digging trenches with the excavation drum 7 attached to the inclined shaft 14, the excavation pawl 22 can pass under the transmission case 6. , it is possible to form a groove of the best shape without leaving any unexcavation between the left and right excavation drums 7, and when backfilling the groove by attaching the backfilling body 50 to the inclined shaft 14, the helical shaft is used. Since the axis of the groove 52 is inclined outward and downward, there is less soil left behind, and more soil can be collected approximately in the center of the trench, making it possible to simply supplement and correct the soil surface that sinks after backfilling. Earth mounding is possible, and even if the helical shaft 52 is long and heavy, the backfill drum 50 can be attached to the inclined shaft 14 by lifting only the inner end while keeping its outer end in contact with the ground. It is easy and safe to put on and take off.
Furthermore, since the mounting portion 51 to which the helical shaft 52 is fixed is formed in a cap shape and surrounds the outer end of the cylindrical inclined shaft 14, the soil collected by the helical shaft 52 is separated from the drive shaft 13. It is possible to prevent the sealing member from getting into the space between the tilting shaft 14 and damaging the sealing member or protective cover therebetween.
