【考案の詳細な説明】
本考案は作業機に関し、極く簡単な構成で以つ
て作業機本体を機枠に横方向に摺動固定自在で、
機枠の摺動面を損傷することなく取付けることを
目的とする。[Detailed description of the invention] The present invention relates to a work machine, which has an extremely simple structure and allows the main body of the work machine to be slid and fixed in the horizontal direction on the machine frame.
The purpose is to install it without damaging the sliding surface of the machine frame.

オフセツト型では、溝は車輪後方に夫々堀削する
ことになり、従つて、従来は条件に応じて溝堀位
置を横方向に変更すると言うことはできず、汎用
性に欠けると言う欠点があつた。 Work machines that are attached to a tractor, such as trench excavators, have a trench excavator body with an auger etc. fixed to a machine frame that is attached to the tractor via left and right support members. The position of the groove was always in a constant relationship to the tractor. In other words, in a tandem type, where the trench digging machine body is located in the lateral center of the tractor, the groove is located in the center between the wheels of the tractor, and in an offset type, where the trench trenching machine body is eccentric to the rear of the tractor wheels, the groove is located in the center between the wheels of the tractor. Therefore, in the past, it was not possible to change the position of the groove in the lateral direction depending on the conditions, and there was a drawback of lack of versatility.
そこで、実公昭57−3366号公報に開示されてい

動自在な筒状取付台を取付け、この取付台を介し
て作業機本体を取付けることが考えられる。 Therefore, as disclosed in Japanese Utility Model Publication No. 57-3366, it is possible to attach a cylindrical mounting base that is slidable laterally to the machine frame via a set piece, and to attach the main body of the work machine via this mounting base. Conceivable.

際に脱落してしまう虞れがある。 However, if the machine frame is supported at both ends by the tractor via the left and right members, and the mounting base is cylindrical, the mounting base must be fitted to the machine frame from the end after the left and right members are removed, making the work difficult. It becomes extremely troublesome to install the machine. Further, by interposing a set piece between the mounting base and the machine frame, damage to the sliding surface of the machine frame can be prevented, but there is a risk that the set piece may fall off when the mounting base slides.

作業等もできる。 When excavating a drainage ditch or the like in a field, it is desirable for operation to position the trench excavator main body 16 at the lateral center of the tractor 1 at locations other than the edge of the bank. It is necessary to position it as close to the edge as possible, such as by positioning it behind one of the rear wheels 2. Therefore, in such a case, the lateral position of the trench excavator main body 16 with respect to the machine frame 10 is adjusted as follows. First, after loosening the bolts 28 to release the pressing and fixing by the holding plate 32, loosen the bolts 31 and remove the member 30, or remove the mounting base 24.
The clamping of the machine frame 10 by this member 30 is loosened and released. As a result, the mounting base 24 can be slid laterally with respect to the machine frame 10, so the mounting base 24 can be slid along the machine frame 10 to position the trench excavator main body 16 at a predetermined position. After that, the bolts 31 are tightened and the machine frame 10 is held between the mounting base 24 and the member 30.
Then, when the bolts 28 are tightened and the press plate 32 is pressed and fixed to the upper surface of the machine frame 10, the trench excavator main body 16 is completely fixed to the machine frame 10.
Therefore, the lateral position of the trench excavator main body 16 can be easily and arbitrarily adjusted, and in particular, since the U-shaped mounting base 24 and the member 30 are used, the structure of the adjustment mechanism for the machine frame 10 can also be adjusted. It's easy. In addition, a holding plate 32 is interposed between the mounting base 24 and the machine frame 10, and this is fixed by pressing it against the machine frame 10 with bolts 28, so that the bolts 28 are brought into direct contact with the machine frame 10. Damage to the machine frame 10 can also be prevented compared to the case where the machine frame 10 is damaged. Note that if the trench excavator main body 16 is located in the center of the tractor 1, work such as repairing a trench once dug can be performed.
取付台24は前方開放状にして伝動ケース17
等の溝掘機本体16側に取付けておいても良い。 The mounting base 24 is open in the front and the transmission case 17 is
It may be attached to the trench excavator main body 16 side.

ものである。 5 and 6 show comparative examples.
There are various mounting structures for attaching the trench excavator main body 16 to the machine frame 10 so as to be slidably fixed thereto.
A pin 35 is inserted into the mounting base 24 and the machine frame 10 to enable adjustment, and a set bolt 36 that contacts the machine frame 10 is screwed into the mounting base 24.
このようにすれば、機枠10に多数のピン孔3

例のような本考案によれば、このような問題点を
すべて解消できるのである。 By doing this, a large number of pin holes 3 can be formed in the machine frame 10.
4, there is a problem in terms of the strength of the machine frame 10, and adjustment is also determined by the pitch of the pin holes 34, making it impossible to perform stepless adjustment. Moreover, the set bolt 36 can be connected directly to the machine frame 1.
0, there is a drawback that damage to the sliding surface on the machine frame 10 side becomes significant. On the other hand, according to the present invention such as the above-mentioned embodiment, all such problems can be solved.
本考案によれば、機枠に対し作業機本体を取付
ける取付台がコ字状であつても機枠に嵌合される
ので、機枠が両端支持されるものでも、左右支持
部材を取外して機枠端部から嵌合させるといつた
必要がなく、作業機の装着が簡単に行なえる。 According to the present invention, even if the mounting base for attaching the work equipment body to the machine frame is U-shaped, it will fit into the machine frame, so even if the machine frame is supported at both ends, the left and right support members can be removed. Fitting from the end of the machine frame eliminates the need for fitting, making it easy to attach the work machine.

とができる。 In addition, the mounting base is fixed by pressing the holding plate with bolts and pressing it against the machine frame, which prevents damage to the sliding surface on the machine frame side, but this holding plate is attached to the mounting stand at both horizontal ends. Since it is equipped with a matching retaining part, the holding plate will not fall off when the mounting base is slid. Moreover, the holding plate is inserted between the mounting stand and the machine frame from the open end side of the mounting base, so after inserting this holding plate from the open end side, attach this member to the mounting stand with bolts. As a result, the holding plate can be easily interposed between the mounting base and the machine frame even though it has the retaining portions at both ends.
