Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to the configuration of a ridge former for changing the height of ridges in a multi-seeding device.

(b) Prior art The height and width of the ridges used to sow seeds while laying mulch film differs depending on the region and crop, but the ridge shapers attached to conventional mulch seeding devices, etc. The height of the ridge can be adjusted by sliding the forming plate left and right, and the height of the ridge can be adjusted by raising and lowering the entire multi-seeding device by raising and lowering the hitch, or by side forming the upper forming plate with long holes. It was fixed to a board and adjusted up and down within the range of the long hole.

(c) Problems that the invention attempts to solve However, when the hitch is moved up and down as shown above,
Since the side forming plates also move up and down, the hem of the ridge cannot be formed as specified. In addition, if the height is adjusted within the range of the long hole that fixes the upper molding plate,
The problem was that the adjustment range was small.

(d) Means for solving the problems In view of the above points, the present invention is constructed as follows.

In a multi-seeding device that performs ridge formation and sows seeds while laying a mulch film, seeds are passed through the upper forming plate 22 that forms the top surface of the ridge when it matches the seeding hole 9a of the mulch film 9 passing above. A grounding shoe 42 with a seed drop hole 42a opened, and a film support rod 27 that supports the multi-film 9 in a suspended state from below are provided above the grounding shoe 42, and the upper molding plate 22 is held together with the film pressing body A. It is adjustable up and down.

A drive shaft 11 is installed horizontally on the seeding frame, and seeding devices 12, 12, . . . are attached thereto.

Any number of seeding devices 12 can be installed. A roller frame 24 is protruded from the rear end of the seeding beam 5 so as to be movable up and down, and a pressure roller 25 is attached to the rear end of the roller frame 24 to press down the upper surface of the multi-film 9 having seeding holes 9a.
is installed.

And, on the lower surface of the seeding beam 5, a mounting rod 5b,
5c is protruded and the ridge forming device of the present invention is attached.

As shown in FIG. 2, the ridge forming machine has side covers 13, 13 fixed to the front surface of the mounting pipes 7, 7, and side forming plates 21, 21 fixed to the lower part of the side covers 13, 13. . The upper molding plate 22 is pivotally connected to the lower end of the support pipe 17 so that its angle can be adjusted.

That is, the plate 28 is placed in the middle of the support pipe 17.
The upper part of the angle-changing handle 36 is pivotally supported by protruding from the base 2 of the upper molding plate 22.
It is pivotally supported on a mounting plate 22b protruding from 2a.

Further, the lower end of the support pipe 17 is also pivotally supported on the mounting plate 22c on the base 22a, and the angle-changing handle 3
The angle of the upper molding plate 22 can be changed by turning 6.

The upper molding plate 22 has slide plates 22d, 2 on both sides.
2d is attached so that it can slide left and right, allowing the width to be adjusted. And bolts 37, 3 on both sides
7... are inserted and fixed into one of the elongated holes 21a, 21a... which are protruded and opened in the side molded plates 21, 21.

A mounting bar 39 is installed horizontally at the rear end of the base 22a, a support member 40 is provided rearwardly protruding from the center of the mounting bar 39, and a film support rod 27 for guiding the multi-film 9 is attached to the rear end. There is. The film support rod 27 supports the multi-film 9 in a floating state from below above the ground shoe 42, and is a film pressing body A that presses the multi-film 9.
between the multi-film 9 and the guide pipe 3.
This constitutes a recess in which the seeds from No. 3 remain.

Further, the front ends of the grounding shoes 42, 42 are inserted into the mounting bar 39, and the grounding shoes 42 have a seed drop hole 42a opened in the center, and receiving rods 42b on both sides thereof.
is installed. When the seed drop hole 42a and the sowing hole 9a of the multi-film 9 match, the seeds accumulated in the recess formed by the film pressing body A on the multi-film 9 are transferred from the seed drop hole 42a to the seeding groove in the soil. fall inside.

The support pipe 17 with the upper forming plate 22 attached
is a mounting rod 5b protruding downward from the seeding beam 5.
and is fixed with a pin 23. Several pin holes 5d are opened in the mounting rod 5b so that the height can be changed, and the height of the upper molded plate 22, the upper guide rod 29, the grounding shoe 42, etc. can be changed at the same time.

Further, a mounting pipe 34 is fitted into the mounting rod 5c, and pin holes 5e are opened at several places in the mounting rod 5c.
A pin 35 is inserted into one of the holes to fix it. An upper surface guide rod 29 is attached to the lower end of the mounting pipe 34, and a support rod 43 is provided protruding from the rear part of the middle portion, into which the mounting rod 31 is inserted. A film pressing member A is fitted into the mounting rod 31 and positioned above the grounding shoe 42 .

As shown in FIG.
A presser rod 32 and a guide pipe 33 are fixed to the lower end of the support body 44, and seeds falling from the guide pipe 33 are held by the presser rod 32.
It is stopped in the depression made by.

Then, an elastic body 47 is provided on the rear surface of the support body 44 to receive the seeds so that they do not climb over the film support rod 27 as the multi-film 9 moves rearward.
is permanently installed.

The guide pipe 33 communicates with the lower end of the seeding device 12 via a guide hose 38.

FIG. 7 shows that the front end of the seeding beam 5 is fitted into the receiving rod 1 which projects rearward from the tool bar 3 in an L-shape so that the position can be adjusted up and down, and the upper molding plate 22, the grounding shoe 42, the upper guide rod 29, etc. This eliminates the need for a pipe for vertical adjustment, allowing the device to be raised and lowered at once, simplifying the effort required for adjustment.

(f) Function of the device With this structure, if you want to increase the height of the ridge, lift the support pipe 17 to a high position as shown in FIG. Long hole 21 opened in molded plate 21
All you have to do is insert it at the top of a and stop it. Then, the mounting pipe 3 equipped with the film pressing body A
4 may be lifted to match the height of the grounding shoe 42.

In addition, as shown in Figure 5 when creating a ridge with an intermediate height, and as shown in Figure 6 when making it even lower, insert the bolt 37 into the intermediate or lower elongated hole, and also install the support pipe 17 and the mounting pipe 34, respectively. By inserting pins 23 and 35 according to the height, the desired height of the ridge can be achieved.

(g) Effects of the invention With the above configuration, the invention provides the following effects.

First, since the upper forming plate 22 can be moved up and down in stages, the ridge height can now be adjusted to a desired height.

Second, since the upper molded plate 22 is moved up and down together with the grounding shoe 42, the film support rod 27, etc., adjustments thereof can be made easily.
