A large number of tilling claws 3 are attached to 2 in the radial direction. Rotating axis 2
is capable of forward and reverse rotation; FIG. 2 shows the reverse rotation state, and FIG. 3 shows the normal rotation state. 4 indicates the entire rotor consisting of the rotating shaft 2 and the tilling claws 3. A fixed cover plate 5 is provided above the tilling rotor 4, and a leveling plate 6 that is vertically movable is attached to a shaft 7 behind the fixed cover plate 5. A fixed support rod 8 protruding rearward is provided at the rear end of the fixed cover plate 5, and the fixed support rod 8
A vertically movable rod 9 is passed through a through hole in the L downward direction provided in the vertically movable rod 9, and the lower end of the vertically movable rod 9 is pivoted 11 to a projection 10 protruding from the rear surface of the leveling plate 6. A collar 12 is provided above the fixed support rod 8 of the vertical movable rod 9, a spring 13 is wound between the collar 12 and the fixed support rod 8, and another collar 1 is provided at a position below the fixed support rod 8.
4 is provided, and a spring 15 is wound between the fixed support rod 8 and the collar 14. Therefore, the lower end of the leveling plate 6 is connected to the spring 13 and the spring 1.
5, it moves up and down elastically. A U-shaped metal fitting 16 is attached to the shaft 17. Reference numeral 17 denotes a boss to which the base of the metal fitting 16 is pivoted, and is pivoted to the shaft 7. Reference numeral 18 denotes an operating lever that projects upward from the metal fitting 16. 19 is the switching lever, L
It is formed into a mold and passes through the base 20 of the metal fitting 16 so as to be slidable in the left and right directions. A spring 2 is attached to the outer periphery of the base 20.
The switch is switched by turning 1 and pushing the collar 22 with the handle 21, and 8-19 is always biased in the direction of arrow A. The tip of the switch/<-i9 is formed into a retaining part 23 bent parallel to the base part 20. An engagement plate 25 having a through hole 24 into which the engagement portion 23 engages is provided on the upper surface of the fixed cover plate 5. A U-shaped ring 27 is welded around the through hole 24 at the upper end of the engagement plate 25 in order to form a guide groove 26 for guiding the retaining part 23.
Ｕ型環２７は金具１６より遠い側が開口２８している。The U-shaped ring 27 has an opening 28 on the side farther from the metal fitting 16.
係合板２５に切替レバー１９の係合部２３を係合させる
と、第２図の如く比較的耕耘ローター４に近付く位置と
なる櫛歯２９をポス１７に固定する。When the engaging portion 23 of the switching lever 19 is engaged with the engaging plate 25, the comb teeth 29, which are located relatively close to the tilling rotor 4 as shown in FIG. 2, are fixed to the post 17.

するようになる。On the outer periphery of the flat plate 6, there is an engagement plate 3 that is symmetrical to the engagement plate 25.
Set 0. A retaining hole 31 into which the engaging portion 23 engages is provided at the upper end of the engaging plate 30. U-shaped ring 27 around the retaining hole 3I
It is surrounded by a symmetrical U-shaped ring 32. Said switching lever】9
3, the comb teeth 29 come into close contact with the back side of the leveling plate 6, and the leveling plate 6 and the comb teeth 29 move up and down together.
（作用） 次に作用を述べる。(effect) Next, we will discuss the effect.
金具１６および切替レバー１９等は左右に２箇所形成さ
れており、場合により３箇、所取付ける。したがって、
係合部２３は単独では保合孔２４．３１に係合しない。The metal fittings 16, the switching lever 19, etc. are formed at two locations on the left and right, and may be attached at three locations depending on the case. therefore,
The engaging portion 23 does not engage with the retaining hole 24.31 by itself.

４で掘起した土を均平する櫛歯としての作用を奏する。Therefore, the switching lever 19 is moved to the engagement plate 25 as shown in FIG.
When engaged with the through hole 24 of the rotor, the rotor is in the reverse tilling position, the comb teeth 29 are located near the tilling rotor 4, and
Since it has an immovable structure with respect to the fixed cover plate 5, it functions as a comb for leveling the soil dug up by the tilling rotor 4.

When this is rotated as shown in FIG. 1 and the engaging portion 23 is brought into contact with the inside of the U-shaped ring 32 and engaged with the engaging hole 31, the third
(As shown by &, the comb teeth 29 are located on the inner surface side of the leveling plate 6, and the rotor is at the stationary tilling position.
そして、均平板６はバネ１３．）九ネ１５により弾力的
に支持されているので、土壌の状態に応して上下動し、
櫛歯２９も均平板６と一緒に１−、ドタ１する。The leveling plate 6 has a spring 13. ) Since it is elastically supported by nine 15, it moves up and down depending on the soil condition,
The comb teeth 29 also move 1- and 1 together with the leveling plate 6.
１、たかって、耕耘ローター４を止転させて耕耘するこ
とができる。1. As a result, the tilling rotor 4 can be stopped and tilled.

5 and 6, the engaging portion 23 is brought into contact with the guide groove 26 as shown in FIGS. In a conventionally known system that can cover a part of the tilling rotor with a fixed cover plate, a leveling plate that moves up and down by spring elasticity is provided behind the cover plate, and a comb is provided between the tilling rotor and the leveling plate. The teeth were provided so that the mounting position could be adjusted freely. However, the comb teeth are simply adjustable in their mounting position, and when the comb teeth are in close contact with the inner surface of the leveling plate, they do not move down -F along with the leveling plate, so the rotor cannot be rotated in the normal direction to perform plowing work smoothly.

耘作業が円滑にできる効果を奏する。However, in the present invention, the northern part of the tilling rotor 4, which can be rotated forward and backward, is covered with a fixed cover plate 5, and a spring force is applied to the rear of the cover plate 5. A movable leveling plate 6 is provided, and the tilling rotor 4
In the one in which comb teeth 29 are provided between and the leveling plate 6,
The comb teeth 29 are arranged in a rotor reverse tilling position, which is located behind the tilling rotor 4 and near the tilling rotor 4, and in a normal rotor rotation position, in which the rotor is in close contact with the inner surface of the leveling plate 6 and is moved downward together with the leveling plate 6. Since it is a comb tooth adjustment device in a forward/reverse tilling device that can be switched between tilling positions, it moves up and down together with the leveling plate, especially when the leveling work is carried out in close contact with the inner surface of the leveling plate. This has the effect of making it possible to smoothly perform tillage work with the rotor stationary.
