Description

[Detailed description of the invention] The present invention relates to an awn removal machine that removes awns, ramus, etc. from rice seed, and it
The purpose is to prevent as much as possible the reduction in product value due to adhesion of powder generated during removal processing.

Normally, when seed rice is sown with a seedling seeding machine,
If the seed rice has awns, stems, etc. attached to it, it will greatly affect the accuracy of sowing, so the seed rice is put in an awn remover to remove the awns and stems.
Remove branches, stems, etc.

By the way, when the awns, ramus, etc. are removed from the seed rice using an awn dehusker, the awns, ramus, etc. are crushed and a white powder is produced, but in the past, no consideration was given to the above-mentioned powder. During the removal process, the white powder was also stirred together with the seed rice.
There was a problem in that it adhered to the rice seeds, turning them white, and reducing the product value of the rice seeds from which awns, stems, etc. had been removed.

The present invention has solved the above problem, and its feature is that a screw body is installed vertically in the hopper to remove awns, stems, etc. from the seed rice by moving the seed rice in the vertical direction. In the awn removal machine, a cover body is provided at the lower end of the screw body, and the upper end opening is substantially sealed by the cover body on the bottom surface inside the hopper, and the powder generated during the above removal process fills the gap between the cover body and the inner surface of the hopper. A reservoir portion through which the powder accumulates is recessed downward, and a discharge path is provided below the reservoir portion to discharge the powder in the reservoir portion to the outside.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In FIGS. 1 and 2, the awn removal machine includes a base 1, a hopper 2, a discharge chute 39, a screw body 3, and an electric Motor 4 and discharge chute 5
, a fan 6, a base-side guide body 7, a tip-side guide body 8, and the like.

The base 1 is shaped like a hollow box that opens downward, and a pair of front and rear bridging members 9 are provided between the left and right side plates in the middle in the height direction. The upper part of the front plate of the base 1 is tilted backward.

The hopper 2 has a cone-shaped lid 10 that opens upward, into which rice seeds are thrown, and has a lid 10 that can be opened and closed.
Fixed by Reference numeral 12 denotes a ground for discharging static electricity on the hopper 2, and is fixed to the hopper 2 with a bolt 11.

As shown in FIGS. 3 to 5, on the bottom of the inside of the hopper 2, there is a ring-shaped reservoir 37 on the lower side in plan view that collects the white powder that is generated when removing awns, stems, etc. from the seed rice. Although it is recessed, its depth is shallow. In addition, on the right side of the lower end of the hopper 2, the discharge port 3 is
8 is formed to penetrate in the vertical direction. Further, the lowermost end of the inner circumferential surface of the hopper 2 is a fitting portion 40 having a constant diameter in the vertical direction.

The discharge chute 39 discharges the white powder in the reservoir 37 to the outside, and its upper end is flange-connected to the lower side of the hopper 2 on the lower surface of the top plate of the base 1, and is connected to the discharge port 38 and to the top plate. The discharge chute 39 is communicated through the formed top plate opening 4, and extends diagonally downward to the right side from the top plate, and its lower end is fixed to the inner surface of the lower part of the right side plate of the base 1. , communicates with the outside of the base 1 through a side plate opening 42 formed in the right side plate. Release chute 3
In the illustrated example, a groove-shaped member with an upward opening is used as 9, but a cylindrical member or a rectangular member may also be used.

The screw body 3 is installed vertically in the hopper 2 and removes awns, branches, etc. from the seed rice by moving the seed rice in the vertical direction. A lower screw portion 14 is spirally disposed around the shaft portion 13 as a left-handed winding, an upper screw portion 15 is spirally disposed around the upper portion of the shaft portion 13 as a right-handed winder in plan view, and a screw portion 15 is fixedly disposed on the lower end of the shaft portion 13. and a disc-shaped cover body 16.

As shown in FIG. 4, the shaft portion 13 is removably fitted onto the upper end portion of the vertically installed mounting shaft 17 that projects inside the hopper 2 so as to be relatively non-rotatable. , cylindrical body 43, and cylindrical body 43
and a mounting hole 45 into which the mounting shaft 17 is inserted into the insertion part 44.
is formed through it.

The cover body 16 seals the upper end opening of the reservoir 37, and the inner and outer peripheries of the lower surface of the cover body 16 slidably contact or face the inner and outer peripheries of the reservoir 37 on the bottom surface inside the hopper 2 with a small gap therebetween.
The two are fitted together with a small gap of about 1 mm between them.
The white powder produced during the removal process passes through the gap between the cover body 16 and the inner surface of the hopper 2 and is accumulated in the accumulation portion 37.

The electric motor 4 is provided between the left side portions of both the crossing members 9, and has an output shaft 20 projecting upward. A transmission shaft 21 is externally fitted and fixed to the output shaft 20 in an upwardly projecting manner, and a pulley 22 is integrally formed at the bottom of the transmission shaft 21.
and a pulley 23 fixed to the lower end of the mounting shaft 17.
A belt 24 is wound between the belt 24 and a winding transmission mechanism 25.
As a result, the screw body 3 is rotated clockwise in plan view.

The discharge chute 5 is for discharging to the outside the processed material such as awns, ramus, and the seeds from which they have been removed from the hopper 2. The discharge chute 5 is provided to project obliquely forward and downward from the front side of the outer peripheral part of the lower end of the hopper 2. ing. The discharge chute 5 includes a first chute 26 that is integrally formed on the front side of the outer circumferential portion of the lower end of the hopper 2, and a second chute 27 that is connected to the first chute 26 in a continuous manner.

The base end opening of the first chute 26 is communicated with the lowest end region inside the hopper 2, and the first chute 26 is provided with a shutter 28 that can be moved in and out in the vertical direction to open and close the internal passage. There is.

The second chute 27 is fixed to the rearwardly inclined upper part of the front plate of the base 1, and its base end is fitted onto the tip of the first chute 26. The tip of the second chute 27 is a seed discharge port 2 that opens diagonally downward to the front and discharges the seed to the outside.
9, and on the top wall side of the middle part of the second chute 27, there is a foreign matter discharge port 30 which projects diagonally upward in the front and opens and discharges foreign matter such as awns and stems to the outside. It is equipped. External chutes 31 and 32 are further connected to each of the discharge ports 29 and 30.

An air blowing port 33 is formed at the base side of the bottom wall of the second chute 27 and at a portion of the upper part of the front plate of the base 1 that corresponds to the foreign matter discharge port 30 . Reference numeral 34 denotes a wire mesh for preventing rice seeds from falling, which is stretched below the air outlet 33 at the upper part of the front plate of the base 1 to prevent the rice seeds from falling from the air outlet 33.

The fan 6 blows air through the guide bodies 7 and 8 and the air outlet 33 to the material to be processed in the discharge chute 5 to remove foreign matter in the material from the material to be processed through the foreign material discharge port 30 and the external chute 3.
2, and is fixed to the upper end of the transmission shaft 21.

According to the embodiment configured as described above, when working with the awning machine, the shutter 28 of the first chute 26 is closed, and the seed rice to be processed is thrown into the hopper 2, and The screw body 3 is rotationally driven by a motor 4 clockwise in plan view.

As a result, the seed rice in the lower area of the hopper 2 is pushed up by the lower screw part 14, and the hopper 2
The rice seeds in the upper area of the hopper are pushed down by the upper screw part 15, and these seeds are pressed against each other in the middle area in the vertical direction inside the hopper 2, and are rubbed together and have a loosening effect. As a result, awns, ramus, etc. are successfully removed from the seed rice, and unlike the conventional method, where awns, ramus, etc. are removed directly from the seed rice using a rotating body such as a metal, there is no need to damage the seed rice. The above removal work can be done without any problems.

During the above removal process, awns, twigs, etc. are crushed and white powder is produced; Since the reservoir 37 that accumulates through the gap between the body 16 and the inner surface of the hopper 2 is recessed downward, the white powder generated during the removal process falls and is collected in the reservoir 37. There is little risk that the product value of the rice seed from which the awns, twigs, etc. have been removed will be reduced by stirring with the rice seed and adhering to the rice seed, turning the seed rice white.

Further, as described above, the upper end opening of the reservoir 37 is made substantially sealed by the cover body 16, and the cover body 16 is also attached to the fitting part 40 at the lowermost end on the inner circumferential surface of the hopper 2 by 0.5 mm. Since they are fitted through a small gap of about mm, there is no risk that the seeds, awns, twigs, etc. in the hopper 2 will enter the reservoir 37.

Then, after a predetermined period of time has passed, the awns from the seed rice,
When the removal work of the awns, twigs, etc. is completed, the shutter 28 is pulled upward to open the internal passage of the first chute 26, and as a result, the awns, twigs, and the like in the hopper 2 are removed. Processed materials such as rice seeds flow into the discharge chute 5. In this case, since the screw body 3 is rotating, almost all of the processed material in the hopper 2 flows into the discharge chute 5.

The processed material that has flowed into the discharge chute 5 receives wind from the fan 6 through the guide bodies 7 and 8 and the air outlet 33 during its movement within the second chute 27, and is sorted and processed. Foreign matter such as awns, twigs, garbage, twigs, and lightly defective rice seeds in the material are blown away and discharged to the outside through the foreign material discharge port 30 and the external chute 32, thereby removing the seeds from the material. Only from the seed discharge port 29, the external chute 3
1 to an external container (not shown).

Further, since the air outlet 33 is covered with a wire mesh 34 for preventing rice seeds from falling, there is no fear that the rice seeds will fall from the air outlet 33.

After the above work is completed, the lid 10 of the hopper 2 is
After removing the screw body 3 from the mounting shaft 17, use a brush or the like to put the white powder in the reservoir 37 into the discharge port 38. 41 and the discharge chute 39, it can be taken out from the side plate opening 42 into a container (not shown).

In addition, as shown by the imaginary lines in FIGS. 3 and 5,
On the lower surface of the cover body 16, a plurality of scraping blades 46 whose lower ends are close to the bottom surface of the sump portion 37 are disposed at equal intervals in the circumferential direction. If it is inclined with respect to the radial direction so as to be on the row side, white powder can be well discharged from the discharge port 38 through the discharge chute 39 by the scraping blade 46 during the above-mentioned removal operation, As mentioned above, it is not necessary to remove the screw body 3 and clean the reservoir 37 after the work is completed, which is convenient.

Note that the scraping blades 46 may not be inclined with respect to the radial direction, but may be aligned with the radial direction.

As described in detail above, according to the present invention, the upper end opening on the bottom surface inside the hopper is substantially sealed by the cover member at the lower end of the screw body, and the powder generated during the removal process is separated between the cover member and the inner surface of the hopper. Since the reservoir is recessed downward to collect through the gap, there is little risk that the powder will be mixed with the seed rice and adhere to the rice seed. There is little risk that the product value of the removed rice seeds will decrease, and there is also no risk that the seeds, etc. in the hopper will enter the reservoir. Further, since a discharge path is provided below the reservoir and discharges the powder in the reservoir to the outside, the powder in the reservoir can be easily taken out through the discharge channel by removing the screw body or the like. The present invention has the various advantages mentioned above and is of great practical benefit.
