［産業上の利用分野］
この考案は、耕耘装置の後方を覆うリヤカバー
に関する。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a rear cover that covers the rear of a tiller.
［従来技術およびその問題点］
耕耘部の上方を覆う上面カバーの後部に主副２
枚のカバーからなるリヤカバーを枢着したものが
ある。そして、通常のロータリ耕耘作業を行う場

いる。[Prior art and its problems] Main and sub-2
There is one that has a rear cover consisting of two covers that are pivoted together. When performing normal rotary tillage work, the two rear covers are fixed together and the combined body is pivoted to the top cover so as to be able to swing back and forth, allowing for simultaneous ridge-building work. In this case, the main rear cover is fixed to the top cover, and only the auxiliary rear cover is swung back and forth.
このような従来技術を示すものとしては、特開
昭54−117707号公報、実開昭57−20804号公報に
記載されたものが存在しているが、前者の形態は

の回動体がカバーとしての機能を果たさない欠点
がある。 Examples of such prior art include those described in Japanese Unexamined Patent Publication No. 54-117707 and Japanese Utility Model Application No. 57-20804, but the former form is a uniform type that corresponds to an auxiliary rear cover. It was devised for the purpose of adjusting the ground contact angle of the flat plate, and
Since this device uses a rotating body corresponding to the main rear cover that is rotated significantly upward, there is a drawback that this rotating body does not function as a cover.
また、後者の形態では、上面カバーに対する主
リヤカバーの角度を調節する部材と、主副リヤカ

る。 In addition, in the latter form, the member that adjusts the angle of the main rear cover with respect to the top cover and the member that fixes the main and sub rear covers are separate structures, which has the disadvantage of increasing the number of parts and increasing manufacturing costs. In addition, there is a drawback that the operation when adjusting the rear cover depending on the work type is cumbersome.

副リヤカバー３の下縁で均平にされる。 At this time, the auxiliary rear cover 3 is movable up and down with respect to the main rear cover 2, and when the tilling operation is performed, the tilled soil that is tilled and blown backward by the tilling claws 13, 13... As the subsequent ridge erector 23 advances, ridges are formed while being pushed left and right to form a groove in the center, and the upper surface of the ridge is leveled by the lower edge of the sub rear cover 3 that is pressurized.
なお、この際、主リヤカバー２は耕耘部後上方
を覆つた状態で上面カバー１に固定されているの
で、後方に放てきされた土を良好に受け止めなが
ら土壌上面を押圧均平できる。 At this time, since the main rear cover 2 is fixed to the top cover 1 while covering the rear and upper part of the tilling section, the top surface of the soil can be pressed and leveled while well receiving the soil thrown backward.
耕深の変更等によつて畦高さが異なるときに

りに上下に回動自在となる。 Further, when performing tillage leveling work alone, the ridge stand device 23 is removed and gauge wheels are attached to the left and right rear ends of the support frame 22. Then, remove the tip hook portion 5a of the locking tool 5 from the holder 4 in the manner described above, rotate it downward around the bent portion 5b, and attach the bracket 19 of the sub rear cover 3.
is engaged and held in the engagement hole 19a. For this reason,
The main rear covers 2 and 3 are integrally pivotable up and down about a support shaft 15.
こうして耕耘作業を開始すれば、土壌は所定
幅、所定深さに耕起され、その表面部は主・副一
体となつたリヤカバー３０の下縁で均平にされ
る。 When the tilling work is started in this way, the soil is plowed to a predetermined width and depth, and its surface is leveled by the lower edge of the rear cover 30, which is integrated into the main and sub-units.
［考案の効果］
この考案は前記の如く構成したものであるか

る。 That is, a fixed top cover 1 that covers the top of the tilling section.
and a rear cover 30 pivotally attached to the rear part of the top cover 1, the rear cover 30 is composed of a main rear cover 2 and an auxiliary rear cover 3 pivotably attached to the main rear cover 2, and is configured to be mutually foldable. In the device, a holder 4 having a plurality of locking portions is provided at the rear of the top cover 1 and projects diagonally rearward and upward, and a single holder 5 having one end pivoted on the main rear cover 2 is used to hold the above-mentioned holder. Since the locking tool 5 is configured to be removable from the tool 4 and also lockable to the locking portion 19a on the side of the sub-rear cover 3, the ridge erector can be attached to the rear central part of the tilling device. When performing ridge work, the main rear cover 2 can be fixed at any angle with respect to the top cover 1, and in this case, since the angle of the main rear cover 2 with respect to the top cover 1 is small, the main rear cover 2 can be fixed at any angle. No matter where the fixing position is, the rear and upper part of the tilling part can be completely covered, and it can also function satisfactorily as the rear cover 30.
