Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a seeding machine for spot-sowing seeds.

(b) Conventional technology Conventionally, a feeding roller is pivotally supported at the bottom of a seed tank,
A seeding machine having a guide tube connected to its discharge side is already known.

(c) Problems to be solved by the invention The feed roller in the known seeding machine has a plurality of grooves on its circumferential surface, and the seeds that have entered each groove are intermittently fed out by rotating the intermittent feed roll to perform spot sowing. However, depending on the rotation angle of the intermittent feeding roller, the seeds in one groove break up and fall one after another, resulting in a row-sown pattern, resulting in poor ventilation during growth, which makes it more susceptible to pests and diseases, and is exposed to sunlight. irradiation to the ground.

(d) Means for solving the problem The present invention is a seeding machine for sowing seeds coated with iron powder, in which a feed-out roller is pivotally supported at the bottom of a seed tank, and is guided to the discharge side of the feed-out roller. Cylinder 1
2 are connected in series, and a reciprocating discharge device is attached to the guide cylinder to collectively discharge the seeds intermittently fed out by the feeding roller, and this reciprocating discharge device is connected to a receiving plate having a discharge hole and the discharge port. and a sliding body that reciprocates on a receiving plate and has an accommodation hole, and a magnet is embedded in the receiving plate to be located on the lower surface of the accommodation hole when the sliding body moves back to receive seeds. The above-mentioned problems are solved by attracting the intermittently fed seeds stored in the sliding body of the reciprocating type discharging device with a magnet to prevent them from scattering and sowing them in a well-collected manner.

(E) Effect When the feeding roller is rotated while the machine is running, the seeds in the seed tank enter each groove of the feeding roller and are fed out in approximate amounts toward the guide tube, and a predetermined amount of seeds that fall through the guide tube. The seeds flow into the storage hole of the sliding body of the reciprocating discharge device, and at this time, since the seeds are coated with iron powder, the magnets absorb the seeds, and they are collected without scattering and are sown in the field. be done.

(F) Example The seeding machine of the present invention is not only a traveling or riding type sowing machine but also a machine that is attached to other working machines, such as a fertilizer application machine. To explain, the fuselage 1 has a center float 2 and side floats 3, 3 at the bottom, and left and right wheels 4, 4, and feed rollers 5, which will be described later, are driven by an engine 6 provided at the front.

The seeding device is attached to the rear of the machine body 1 by a connecting rod 7, etc., and a pair of feed rollers 5, 5 are fixed to rotating shafts 10, 10 at the bottom of a pair of seed tanks 8, 8, respectively. , each feeding roller 5... has grooves 11 at three equally spaced locations on the outer periphery, and a guide tube 12 is connected to the discharge side of the feeding roller 5.

A reciprocating type discharge device is attached to the lower part of the guide tube 12, and the reciprocating type discharge device has a case 17 having a receiving plate 15 and a discharge port 16 at the lower part, and a case 17 having a narrow rear part in the extrusion direction. a movable plate 20 having a housing hole 18; a rod 23 that protrudes from one end of the movable plate 20 to the outside of the case 17, fixes a plate 21 to the end and is biased by a compression spring 22; 10,
10, it is composed of a shaft 24 that rotates three times each time it rotates, and a disk-shaped (or elliptical) eccentric cam 25 fixed to the shaft 24. When this happens, the housing hole 18 is aligned with the magnet 26 fitted and fixed to the receiving plate 15 and the lower end opening of the guide tube 12, and at the bottom of both sides of the housing hole 18 there are notched grooves 18a that communicate with each other from side to side. 18a is bored.

Further, the alarm device includes a light emitting diode 27 and a phototransistor 28 attached to both sides of the case 17 and facing each other directly under the lower end opening of the guide tube 12, an amplifier 29 shown in FIG. 5, a timer 30, a buzzer 31, and the eccentric The light emitting diode 27 and phototransistor 28 are connected to the cutout groove 18 when seeds are received.
a, facing 18a.

When the rotary shaft 10 and the shaft 24 are driven while the machine body is running in the seeding machine described above, the seed tank 8
The seeds inside are fed out by the groove 11 of the feeding roller 5 and fall into the guide tube 12.

At this time, the movable plate 20 has moved from the position shown in FIG.
When all the seeds that have been scraped out at once have fallen and the state shown in Figure 1 is reached, the switch 32 is pressed to turn it on.Then, as shown in Figure 2, the eccentric cam 25 The movable plate 20 is pushed out while being compressed.

The seeds that have fallen onto the movable plate 20 are pushed into the accommodation hole 18 by the lower edge of the guide tube 12 during the return stroke, and the seeds are collected in the narrowed part of the accommodation hole 18 during the extrusion stroke of the movable plate 20. and the accommodation hole 18
As shown in FIG. 3, when the seeds reach the discharge port 16, they fall all at once in a well-clumped state and are sown on the plowed field.

The seeds, such as the aforementioned rice seeds, are coated with a mixture of an oxygen generating agent such as Calper (trade name) and fine particles of iron powder, so when the seeds fall into the storage hole 18, they are absorbed by the magnet 26. This can prevent it from scattering.

When the sowing is finished, the movable plate 20 is moved to the left by the compression spring 23, and near the limit of movement, the switch 32 is moved by the eccentric cam 25.
It becomes ON.

At that time, the seeds in the seed tank 8 may disappear or the groove may become clogged, causing the seeds to fall into the storage hole 1.
8, the light emitting diode 2
Since the detector consisting of 7 and phototransistor 28 is not detected, the non-detection signal is sent to the amplifier 29.
The buzzer 31 issues an alarm.

(G) Effects of the invention The present invention is a seeding machine for sowing seeds coated with iron powder as described above, in which a feed-out roller 5 is pivotally supported at the bottom of a seed tank, and a feed-out roller 5 is mounted on the discharge side of the feed-out roller 5. A guide tube 12 is provided in series, a reciprocating type discharge device is attached to the guide tube 12 for collectively discharging the seeds intermittently fed out by the feed roller 5, and this reciprocating type discharge device is connected to a receiving plate having a discharge hole. and a sliding body that reciprocates on the discharge port and the receiving plate and has an accommodation hole 18, and is located on the lower surface of the accommodation hole 18 when the sliding body moves back to receive seeds on the receiving plate 15. Since the magnet 26 is buried, the seeds with iron powder that fall apart from the groove of the feed roller 5 and fall into the guide tube 12 are transferred to the receiving hole 18 of the sliding body of the reciprocating discharge device when the reciprocating discharge device returns.
When the seeds fall into the container, they are attracted by the magnet 26 and are extremely unlikely to scatter.As a result, the seeds that have entered the storage hole 18 can be sown together as one plant, improving ventilation during growth. It is possible to prevent the occurrence of pests and diseases, and it is also possible to improve the irradiation of sunlight onto the ground, thereby raising the temperature of the ground.
