Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seeding method and a seeding machine. More specifically, the present invention relates to a sowing method in which a seeding furrow is formed in an untilled state without tilling the soil, and seeds are sown in the sowing furrow, and a seeding machine for realizing this sowing method.

(Prior art) Conventionally, when sowing seeds in a field, the soil is not tilled (a seeding furrow is formed in a no-tillage state, and the seeds are sown in this mu furrow), for example, in accordance with Japanese Utility Model Publication No. 58-8009. This is already known as shown in the publication.

(Problems to be Solved by the Invention) As described above, when sowing without tillage, it is possible to save labor compared to tillage sowing. In the case of cutting and spraying, there are advantages such as less weeds growing because there is no tillage, but the conventional no-till and tillage method of sowing 8i
As shown in the above-mentioned Japanese Utility Model Publication No. 58-8009, the groove is formed by arranging a pair of discs with blades on the periphery in a V-shape, and the groove is shaped with drainage in mind. Because the seedlings are not made in the trenches, there is a problem with poor drainage and rotting of the seeds.On the other hand, when there is a lack of moisture, it is impossible to pump up water from the soil, so it is not possible to There was a problem of water shortage.

The purpose of the present invention is to improve drainage by forming cutting grooves in the vertical direction that are deeper than the seeding groove, and to make it possible to pump up water from the soil in case of water shortage, which is suitable for seed germination. It is an object of the present invention to provide a 1111 seeding method and a seeding machine that can perform seeding and also easily create seeding furrows.

(Means for solving the problem) First invention stated in claim 1 (specified invention)

A seed tank (3) is mounted on the sowing frame (1), and a plate-shaped rotary blade body (4) is provided at the front of the seeding frame (1), and this rotary blade body A groove forming body (5) consisting of a pair of discs (5a) and (5b) is provided behind (4).

The rotary blade body (4) is composed of a disc body, and is rotated by the PTO shaft (6) of the tractor (A) in the direction of the arrow X in FIG. The structure is such that it is forcibly driven.

In the embodiment shown in FIG. 1, the seeding frame (1) is provided with a vertical transmission case (11) and a support leg (not shown), and the lower part of the transmission case (11) and support leg is driven. The shaft (12) is supported by the cane, and this drive shaft (12)
), one or more rotary blades (4) are fixed at predetermined intervals, for example, in the case of four-row sowing.

The power is transmitted to the drive shaft (12) by providing a gear case (13) on the seeding machine frame (1), and connecting the input shaft (14) of the gear case (13) to the PTO shaft (6). A belt transmission mechanism (18) is provided between the output shaft (16) of the gear case (13) and the input shaft (17) of the transmission case (11). It is formed by interposing it.

Further, the groove forming body (5) is rotatably supported at the lower part of the leg body (21) fixed to the split frame (1).

The rotary blade body (4) and the groove forming body (5) are arranged close to each other in the front and rear direction, and the rotary blade body (4)
The lower edge is positioned below the lower edge of the groove forming body (5).

In the one shown in FIG. 1, the rotary blade body (4) is
The discs (5a) and (5b) forming the rotary blade body (5) have a diameter larger than the outer diameter, and are supported at the same height position, and the rotary blade body (5) is supported at the same height position.
4) is configured such that the lower edge thereof is located below the lower edge of the groove forming body (5).

However, as shown in FIG. 3, cutting grooves (31) are formed in the soil by the rotary blade (4), extending in the vertical direction and having a depth longer than the sowing depth position, and the cutting grooves (31) are formed in the soil by the rotary blade (4). Groove body (
5), a wide seeding groove (32) is formed above the cutting groove (31) at the seeding depth position.

In addition, the seed tank (3) is equipped with a rotary feeder (
A seeding pipe (23) is connected via a
This seeding pipe (23) is supported by the leg piece (21) that supports the groove-making body (5), and the lower opening faces the immediate blade of the groove-making body (5).

Further, the seeding frame (1) supports a suppression ring (24) having a plurality of protrusions (24a) on the outer periphery, and
A pulley (26) fixed to the support shaft (25) and a boo U-(28) provided on the rotary shaft (27) of the rotary feeder (22) use the support shaft (25) of the suppression ring (24) as a power extraction shaft. ), and the rotary feeder (22) is driven based on the pressure wheel (24) at a predetermined interval (mainly 30 cm interval).
We are making it possible to sow seeds.

In addition to belt transmission, power transmission to the rotary feeder (22) may be achieved by chain transmission using a chain case, or by using the PTO shaft (6) of the tractor (A).
Power may be taken from.

A method of sowing seeds using the sowing machine configured as described above will be explained based on FIGS. 2 and 3.

When the tractor (A) is driven and moved forward, the soil to be sown by the rotary blade (4) is first cut into a cutting groove (which extends in the vertical direction shown in FIG. 3 and has a depth longer than the sowing depth position).
31) is formed.

The groove width of this cutting groove (31) is determined by the plate thickness of the rotary blade (4), but it is selected according to the particle size of the seeds to be sown. 31) and the sown seeds (33) should not flow into the container.

In addition, the rotary blade body (4) may have a disc shape with a circumferential surface as shown in FIG. , (C), the blade edge may be formed only on the periphery. Thus, by changing the rotary blade (4), the cutting groove formed by the rotary blade (4) changes as shown in FIGS. 5(a), (b), and (c).

The rotary blade body (4) forms the cutting groove (31) as described above, but for example, when harvesting and threshing with a combine harvester, the waste straw is shredded with a cutter and sown in a scattered field, It is preferable that the rotary blade body (4) cuts the scattered straw, etc. and prevents the straw etc. from entering the cutting groove (31). It is preferable to use one with a sharp edge.

Next, a wide seeding groove (32) can be formed by the groove forming body (5) above the cut 11 (31) formed as described above.

Since this seeding groove (32) is formed based on the cutting groove (31), it can be formed without large power consumption, and
Since the cutting groove (31) is formed wider than the cutting groove (31), the seeding groove (32) has a bottom (32a) at the seeding depth position.

Next, the seeds from the seed tank (3) are sown into the seeding groove (32) formed as described above at regular intervals via the rotary feeder (22).

In this way, the seeds sown in the seeding groove (32) are held at the bottom (32a) of the seeding groove (32) without moving to the cutting ?+11 (31), as shown in Fig. 3. Therefore, even if rainwater or the like flows into the seeding groove (32), it can be drained into the soil by the cutting groove (31) extending downward, and the rainwater is stored in the seeding groove (32). This will definitely prevent the seeds from rotting due to this.

Furthermore, in the case of water shortage, the cutting grooves (31) act as capillary tubes and can draw up water from the soil through capillary action, maintaining conditions suitable for seed germination.

In addition, the seeding groove (32) is formed by the groove forming body (5),
The cross-sectional shape of the groove-forming body (5) can be set.

The cross-sectional shape of the seeding groove (32) can be changed by combining a) and (5b). The position fi (0) is shown in Fig. 7(a).
By setting the center part in the vertical direction in the front part as shown in
It can be made into a rectangular cross section, and the butt position (0) can be set as shown in Fig. 7 (
As shown in b), by setting the front part downward in the vertical direction, it becomes an inverted trapezoid shape, and the butt position (0) is
) The shape can be changed to an inverted triangle by changing the shape to the lower part.

In addition, further changes can be made by shifting the center of rotation of the rotating disks (5a) and (5b) in the front-rear direction as shown in FIG.

By deforming the seeding groove (32), the shape of the groove combined with the cutting groove (31) can be changed in various ways as shown in FIGS. 9(a,) to (d).

(Effect of the invention) According to the first invention, since the cutting groove (31) extends below the seeding position of the seeding groove (32) where seeds are sown, the cutting groove (31) allows the seeding groove (32) to be Surplus water such as inflowing rainwater can be reliably discharged, and it is possible to reliably prevent seeds from rotting due to water accumulation in the seeding groove (32), and in case of water shortage, it is possible to pump up soil water. It is possible to create conditions suitable for the germination of sown seeds.

Further, according to the second invention, the rotary blade body (4) is arranged in front of the machine body in the traveling direction, and after first forming the cutting groove (31), the sowing groove (32) is formed by the groove making body (5). Since the seeding groove (32) can be formed reliably, the groove can be formed based on the cutting groove (31), so the groove for seeding can be formed with less power loss and energy saving.
