欠点を有していた。 Conventionally, this type of seeding and mulching equipment is
A take-up roll winding up the perforated film to be coated on the ridges, a sowing machine at the rear upper part of the take-up roll, and a seed discharged from the lower discharge port of the sowing machine below the sowing machine. It is equipped with a hopper that guides the seeder to the groove formed by the furrower, and at the rear of the seeding machine, there is a mulching device that covers the ridge by pressing the edge of the film that covers the top of the ridge. This device is generally known, and the structure of the seeding machine in this type of mulching device is such that the opening/closing lid provided at the lower discharge port of the seeding device is formed of a substantially flat plate, as shown in Figure 2. , and the front end is pivoted in a downwardly inclined rearward direction, and the opening/closing lid is
Since the opening/closing cover is connected in conjunction with a detection rod that detects the hole in the film, and the opening/closing lid is opened and closed when the detection rod falls into the hole, an appropriate amount is fed out by the feed roll in the seeding machine. When the opening/closing lid is opened, the seeds come into contact with this detection rod and are scattered in all directions. It had the disadvantage that it could spill outside.

イルム６の孔７部に臨ませた構成とする。 This invention was proposed to eliminate the above-mentioned drawbacks, and for this purpose, the following technical measures were taken. That is, a furrower 1 that forms a groove for seeding in a field, a sowing machine 2 that supplies seeds into the formed groove, and a perforated film 6 that has a plurality of holes arranged in a row.
A seeding mulching device is equipped with a perforated film take-up roll 5 that winds up a perforated film 6 that is pulled out from the take-up roll 5.
It has a detection rod 9 that opens and closes the opening/closing lid 8 at the bottom of the seeding machine 2 while detecting the hole 7 of the sowing machine 2. Surfaces 8a, 8a are formed, and the lower ends 8b, 8b of these downstream guide surfaces 8a, 8a are made to face the hole 7 portion of the perforated film 6.

供できるのである。 Since this invention is constructed as described above, it has the following technical effects. That is, the holes 7 of the perforated film 6
When the detection rod 9 that has detected the part falls into the hole 7 part, the opening/closing lid 8 linked with this opens and a certain amount of seeds 3 are guided into the groove formed by the groove cutting device 1. However, at this time, the opening/closing lid 8 is provided with flow guide surfaces 8a, 8a that are inclined laterally to avoid the detection rod 9 located directly above the lid 8, and the seeds 3 that have fallen from directly above the detection rod 9 are , this guide surface 8a, 8
Since the seeds 3 are distributed as appropriate in the left and right directions at the point a, the seeds 3 do not hit the detection rod 9 that is linked to the opening/closing lid 8 and are blown out of the holes 7 of the perforated film 6, and the seeds 3 are distributed backwards. The seeds are surely introduced into the hole 7 from the lower ends 8b, 8b of the inclined opening/closing lid 8, and are sequentially fed into the groove formed by the groove cutter 1 located below the seeding machine 2. Therefore, it is possible to provide a highly practical seeding and mulching device with no waste.

られる。 Note that the seeding machine 2 shown in the illustrated example is equipped with a feeding roll 2a supported on a horizontal axis, and this feeding roll 2a is supported on a horizontal axis.
a is a compression wheel 10 that compresses and rolls on the upper surface of the film 6;
By this rotation, seeds 3 stored in the storage section 2b are sent out in an appropriate amount to the hopper 4 from the discharge port section 2c provided at the lower end. The opening/closing lid 8 provided on the discharge port 2c has a central portion bent into a substantially mountain shape, and both left and right slopes thereof serve as guide surfaces for the seeds 3 to flow downward, and a hole 7 detection rod 9 is provided below this bent portion. Its tip is attached to the pivot shaft 11 of the opening/closing lid 8 so that the opening/closing lid 8 is positioned in the same position. When the hole 7 of the film 6 is directly below the discharge port 2c, the detection rod 9 falls into the hole 7 of the film 6 and the opening/closing lid 8 opens, while the part of the film 6 without the hole 7 is directly below the hole 7 of the film 6. At this time, the detection rod 9 is lifted up by the film 6 and the opening/closing lid 8 is closed.
