Description

  TECHNICAL FIELD The present invention relates to a setting device that is mounted on a tilling work machine and pushes up and sets up soil that has been scraped by a tilling rotary.

A cultivator is originally a device that performs a tilling work that scrapes the soil with a tilling rotary, and various devices that can simultaneously perform a tilling work have been proposed and implemented.
For example, the following Patent Document 1 discloses a cocoon forming work machine in which a cocoon forming body is arranged behind the tilling rotary of the working machine body, and the soil cultivated by the rotary is piled up and the side surface of the hoe is formed. ing. However, in this cocoon forming machine, since the cocoon forming body is heavy and the connection structure is complicated, it is very difficult to replace the cocoon forming body when switching between the tilling work and the uprighting work. .
On the other hand, in recent years, using a resistance bar for stable operation of a tilling work machine provided at the rear part of the rotary, a vertical setting device has been implemented in which a vertical earthing device can be attached to and detached from the resistance bar. Yes.

And as shown in FIG.1 and FIG.2, the resistance rod 4 which determines the tilling depth which installed the support fixing | fixed part 5 which can fix the said leveling board 3 in a substantially horizontal state in the center of the rear part of the said rotary cover 2, and And detachably fixed to a part of the outer surface 3d of the leveling plate 3.
5A shows the outer surface 3d of the leveling plate 3, and FIG. 5B shows the support fixing portion 5. FIG. The base end portion of the support fixing portion 5 is connected to the connection hole portion provided on the outer surface 3d of the leveling plate 3 with the insertion portion provided at the tip, and the end portion is connected to the connection hole portion provided in the intermediate portion of the resistance bar 4 It is shown that the flanged insertion part provided in the part is inserted through a large hole and is connected to the small hole connected to the large hole so as not to come out.
Moreover, although not shown in figure, the said support fixing | fixed part 5 can also be provided between the said rotary tiller K main body and a part of outer surface 3d of the said leveling board 3, and the outer surface of the said rotary cover 2 and the said leveling board 3 It is also possible to provide it between a part of 3d. In any of these aspects, the leveling plate 3 can be fixed in a substantially horizontal state with respect to the rotary tiller K main body.

In addition, each culture plate 9 folded so as to be folded into the inner surface 3c of the leveling plate 3 without removing the support fixing part 5 and fixing the leveling plate 3 to the rotary tiller K main body in a substantially horizontal state, When 10 and 11 are fixed to the leveling plate 3 with the folding fixing means 14 and 15, the tip 3b of the leveling plate 3 hits the soil and is cultivated while freely swinging up and down behind the rotary cover 2 Will be roughly leveled from above.
The side of the end portion 3b of the leveling plate 3 may be straight, but if it is bent slightly downward (inward) to form a corrugated shape, the soil can be scraped and leveled like a rake. It is preferable because it can be hidden so as to cover each culture plate folded on the inner surface 3c of the base plate 3.
In addition, the protrusion 26 provided on the inner surface 3c of the ground leveling plate 3 shown in FIG.

The edge of the end portion 3b of the leveling plate 3 may be directly formed in a wavy shape as shown in FIG. 5, but as shown in FIGS. 10 and 11, along the end edge 3b of the leveling plate 3. Then, a plate-like attachment 49 that can be attached and detached by means of attachment and detachment fixing means such as a screw 50 or a pin or a hook can be provided in the hole provided in the end edge 3 b of the leveling plate 3.
The shape of the edge of the tip of the plate-like attachment 49 is formed by taking any cross-sectional shape such as a mountain shape, corrugation, groove shape, etc. It becomes possible to do.
For example, in the embodiment of the plate-like attachment shown in FIG. 10, the top of the reed is formed in a mountain shape by the recessed portion 51 at the center, and the drainage is improved on the downward inclined surfaces on both sides of the reed so that the reed is not easily broken. Will be able to. Furthermore, since the surface area of the cocoon field can be expanded, it is possible to increase the amount of solar radiation hitting the cocoon field. As a result, the temperature of the cocoon increases and the growth of crops can be promoted.
Moreover, the aspect of the plate-like attachment shown in FIG. 11 is a plate-like attachment for forming a two-row groove, which can form two rows of grooves in the cocoon heaven with two protruding portions 52 protruding at intervals, The seed can be easily positioned in this groove when seeding.

  In addition, the erecting body 7 of the present invention is composed of a plurality of soil plates, and various forms are possible, but the following two-sided type (FIGS. 4 and 6) and center-sided type (FIG. 7) are possible. It is. In any form, it can be folded compactly so as not to protrude a plurality of soil slabs from the inner surface 3 c of the leveling plate 3, and can be arbitrarily selected according to the shape of the ridges that stand on the inner surface 3 c of the leveling plate 3. The shaped mulcher plate can be fixed upright at an arbitrary position.

Next, the form of the upright body 7 constituting the apparatus will be described.
