Description

[Detailed explanation of the invention] Industrial application field This invention uses a perforated seeding plate that rotates as the aircraft moves to pump up seeds in a seed box mounted on the aircraft. This invention relates to an improvement in a rotary perforated seeding machine that sows seeds by dropping them through a seeding hole in the upper part of a side plate provided at an angle in a seed box.

Prior Art An example of the prior art is Utility Model Application No. 87509/1983. As shown in FIGS. 5 and 6, this prior art describes a seed extrusion holder C that forcibly pushes out the seeds drawn up through the seed holes B of the perforated seed plate A downward. ing.

Problems to be solved by the invention The above-mentioned seed extrusion holder C is provided to forcefully extrude the seeds drawn up through the seed holes B of the perforated seed plate A toward the ground surface through the seed drop opening of the bottom plate. However, if the diameter of the seed is larger than the diameter of the seed pore B, or if multiple seeds are stuck together, the seed pore B becomes clogged and the seeds cannot be pumped out.

This invention aims to eliminate the drawbacks of the prior art described above, and when the entrance to the seed pore B is blocked by a large seed etc. and the seed cannot fall, the seed is removed by a pusher piece. To provide a rotary perforated plate seeding machine that can continuously pump out seeds by expelling the seeds upward and opening the entrance to the seed hole B.

Means to Solve the Problem Namely, this invention is a perforated seeding method in which a seed box with an inclined side plate is provided on one side of the machine, which is movably supported by ground wheels, and the seed box is slidably slid against the side plate. board,
In conjunction with the grounding ring, the seed hole is rotated so that it can freely rotate, and the seed hole provided in the perforated seeding board can be freely overlapped with the seed hole bored in the upper part of the side plate. In a seeding machine that is arranged at appropriate intervals on the circumference with
The gist of this invention is a structure of a rotary perforated seed seeding machine characterized in that a push-out piece that can be inserted from below is elastically supported by the side plate.

Function Since this device is constructed as described above,
Even if the seed hole entrance is blocked by large seeds, the seeds will be removed upward by the extrusion piece as the machine moves, and the seed hole entrance will be opened. Seeds can be pumped out smoothly.

Embodiment To explain the present invention with reference to an illustrated embodiment, 1 is a fuselage, which is supported by ground wheels 2 and a tail wheel 3 so as to be freely movable, and in the center of the fuselage 1 is a seed box 4.
is highly supported.

The seed box 4 is formed so that the seeds a fed from a hopper 5 provided at the top can be stored at the bottom. A large seeding hole 7 is bored in the upper part. Reference numeral 8 denotes a perforated seeding plate, which is in sliding contact with the side plate 6 so as to be rotatable, and has a rotating shaft 9 at its center. This rotating shaft 9 is linked to the grounding wheel 2 via a chain or the like so as to rotate the seeding plate 8 as the machine body 1 travels. Further, in the seeding plate 8, an appropriate number of seed holes 10, 10, . Reference numeral 11 denotes an extruded piece, which is formed of a rectangular leaf spring. The base of the extruded piece 11 is elastically supported by the side plate 6 so that its tip can be freely inserted into the seed hole 10 of the seed plate 8 through the seed hole 7 of the side plate 6.

To explain the operation of the above embodiment, when the body 1 is pushed forward, the grounding wheel 2 rotates, and the perforated seeding plate 8 rubbing against the upper surface of the side plate 6 rotates accordingly. When the seeding plate 8 rotates, the seeds a at the bottom of the seed box 4 are drawn up by the seed holes 10 formed on the periphery thereof, are released through the seeding holes 7 of the side plate 6, and fall to the ground surface. However, since the push-out piece 11 elastically supported by the side plate 6 can be inserted from below into the seed hole 10 on the upper surface of the seed hole 7, even if a large seed a etc. is located at the entrance of the seed hole 10 in a state where it cannot fall. , those seeds a are expelled upward by the extrusion piece 11, and the seed hole 10 returns to a state in which the seeds a can be freely pumped out.

Effects of the Device As described above, when the present invention is used, even if large-diameter seeds are mixed in the seed box and block the entrance of the seed hole, the seed hole will be able to reach the upper surface of the sowing hole. When this happens, the seed pore entrance is opened by the extrusion piece, which has the practical benefit of allowing the seeds to be pumped out from the next time onwards.
