Description

[Detailed Description of the Invention] The present invention relates to an awn removal machine that removes rice seeds, awns, branches, etc.

Normally, when seed rice is sown with a seeder for raising seedlings, if the seed rice has awns, stems, etc. attached to it, it will greatly affect the accuracy of sowing, so the seed rice is run in an awn remover to remove the awns, stems, etc. There is.

Conventional awn removal machines remove awns and stems by feeding the seeds with a pair of screws placed opposite each other and interfering with each other. Emission is intermittent and de-awning efficiency is poor.

In view of these conventional problems, the present invention moves seed rice while giving it peristaltic motion in a cylindrical body with unevenness.
It is an object of the present invention to provide an awn removal machine capable of removing awns, branches, etc. more reliably and quickly.

In order to achieve this purpose, the present invention has developed
In an awning machine that removes branches and stalks, an awning body has a seed supply port at one end and a discharge port at the other end, and an unevenness is formed on the inner circumferential surface of the awning body. The present invention is characterized in that it has a peristaltic screw which is disposed at the supply port and the discharge port to cause peristaltic movement of the seed rice.

Embodiments of the present invention will be described below with reference to the drawings.

The awning machine 1 is roughly divided into a circular cylinder 2 whose axis is arranged horizontally, an awning body 3 disposed concentrically within the cylinder 2, and an awning body 3 disposed within the awning body 3. a peristaltic screw 4, a hopper 5 that supplies the seed A into the awning body 3;
It has a blowing mechanism 6 that sends air to the gap C between the cylindrical body 2 and the awning body 3, a mechanism 7 that drives the peristaltic screw 4 and the blowing mechanism 6, and a rice seed recovery box 8.

11 is the frame of the awn removal machine 1, and the cylindrical body 2Vi frame 11
It is supported horizontally on the left side and has an enlarged part 13 on the left end and a tightened part 14 on the right end.

As shown in FIGS. 2 and 3, the awn removal body 3 is formed of a cylindrical net or a hunting blade, and is arranged concentrically with the cylindrical body 2 with a gap C, and both ends thereof are open. It has a seed supply port 15 near the left end and a discharge port 16 at the right end.

The hopper 5 is supported by a frame 11, and its supply cylinder 17 passes through the cylinder body 2 and is connected to the supply port 15 of the awning body 3. It is supplied into the removed awn body 3.

The peristaltic screw 4 is arranged concentrically within the awning body 3, and is rotatably supported by the frame 11 at one end and by the cylindrical body 2 at the other end via bearings.

This peristaltic screw 4 has brushes made of synthetic resin that are hard enough not to damage the seed rice A, arranged in a spiral manner on its shaft, and moves the seed rice A supplied from the hopper 5 to the discharge port 16 in the front.

The pinch of the peristaltic screw 4 shown in FIG.
Seed rice A is sent to the rice grains in a rough state, and in the pinch dense area P, the seed rice A is
be sent in close quarters, slowly pushing each other.

That is, the peristaltic screw 4 moves the seed rice A in peristaltic motion while feeding the feed port 15. ') - are moved through the discharge port 16 casing, and on the way, the seeds A rub against each other due to peristaltic motion, and by locking in the holes 18 of the awn removal body 3, the awns B and stems are removed. is separated from the seed rice A75 and falls from the awning body 3 into the cylinder body 2.

The air blowing mechanism 6 (ri) blows away such detached awns B and branches, and is composed of a fan installed at the end of the shaft of the peristaltic screw 4. is discharged from the exhaust tube 21 through the gap C, and the detached awn B and stem stem are discharged from the exhaust tube 21.

25 is a motor of the drive mechanism 7, which drives the peristaltic screw 4 via pulleys 26, 27 and a belt 28.

As shown in Fig. 2 or Fig. 3, the awns B and stems of the seed A enter the holes 31 or mesh 32 of the punching plate 30 that forms the awn-removal body 3, and peristalize. Seed 1
By being pushed by mA, the awn B and the ramus separate.

Even if the casing, awn B, and ramus do not enter the hole 31 or the eye,
If there are holes 31 or eyes, the inner circumferential surface of the awning body 3 has an uneven shape, so that the awning body 3 hits the unevenness and comes off.

Therefore, the awning body 3 is not limited to a porous body, and may be any body having irregularities on its inner circumferential surface.

The gap C (/'i) is formed to allow air to pass through to eliminate detached awns B and stems, and may be provided only below the awn removal body 3. If there are no holes,
A ventilation mechanism is provided near the discharge port 16, and when the seed A is discharged from the front end discharge port 16' of the awn removal body 3, the awns B and the stems which are discharged at the same time are separated and discharged. It is sufficient if it is configured so that the air blows out from the wind tube 21.

The rice seed collection box 8 is disposed below the discharge pipe 40 provided at the right end of the cylinder, and receives the rice seeds falling from the discharge port 16 through the discharge pipe 40.

The collection box 8 can be taken out by the downward force of the discharge tube 40.

According to the present invention described in detail above, the peristaltic screw causes the seed rice to move peristaltically within the dehulled body having irregularities on the inner circumferential surface, so that the awns and ramus can be applied to the circumferential surface of the dehulled body, or other seeds can be removed. It can be reliably separated from the seed rice by applying it to the rice.

Since the awns can be removed without being continuously supplied in the direction of
This can be done automatically in a short time without damaging the seed rice.
