Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pretreatment machine for obtaining seed rice for a seeding device used to obtain seedlings with soil to be attached to a rice transplanter.

(Prior art) In the conventionally known Japanese Utility Model Application Publication No. 17362/1983, a container with a larger diameter toward the top and an opening at the top is provided on a frame, and the bottom of the container has an upper end of a vertical shaft rotated by a motor. The lower part of the stirring spiral is attached to the upper end of the vertical shaft, and the stirring spiral is formed into a downward feeding spiral. Furthermore, in the conventionally known Japanese Utility Model Publication No. 53-41473, the left half is formed into a right feeding spiral body, the right half is formed into a left feeding spiral body, and the seed awn is removed between the right feeding spiral body and the left feeding spiral body. A pretreatment machine for obtaining seed rice for sowing is described, which has an awn removal section formed therein. Also, JP-A-52-
Publication No. 132458 describes a wet grinding device in which a plurality of right-hand feed spiral bodies and a plurality of left-hand feed spiral bodies are provided facing each other on a horizontal axis.

(Problems to be Solved by the Invention) The device disclosed in Japanese Utility Model Application Publication No. 48-17362 has only a downward feed stirring spiral attached to the vertical shaft.
The awn removal action is not sufficient. The product disclosed in Japanese Utility Model Publication No. 53-41473 has a right-handed stirring spiral and a left-handed stirring spiral attached to the horizontal axis, so the paddy accumulates at the bottom due to its own weight and the pressure increases as it goes down, so the awn removal effect is It cannot be done evenly. The device disclosed in JP-A-52-132458 is not only a wet crushing device, but also has a horizontal axis, so the paddy accumulates at the bottom due to its own weight and the pressure increases as it goes down, so the awn removal action cannot be made uniform.

(Means for Solving the Problem) Therefore, the present invention provides a container 6 on the underframe 1, which has a larger diameter toward the upper part and is open at the top, and the upper end 3 of the vertical shaft 2 of the motor a is provided at the bottom of the container 6. The lower part of the stirring spiral 11 is detachably attached to the upper end 3 of the vertical shaft 2, the upper half of the stirring spiral 11 is formed as a lower feed spiral 13, the lower half is formed as an upper feed spiral 14, and the lower This is a pre-processing machine for obtaining seed rice for sowing, in which an awn removing part 15 for removing awns from the seed rice is formed between the feeding spiral body 13 and the upper feeding spiral body 14.

(Example) An example of the present invention will be described with reference to the drawings.
is a frame, which has a square box shape, and inside,
A vertical shaft 2 and a motor a for rotating it are attached. 4 and 5 are bearings for fixing the vertical shaft 2. The upper end 3 of the vertical shaft 2
protrudes upward from the underframe 1, and the container 6 is placed there.
Install. The container 6 has a horizontal bottom wall 7 at the lower end, has a hopper shape whose diameter gradually increases as it goes above the bottom wall 7, and is open at the top and covered with a lid 8. The bottom wall 7 is a perfect circle, and a vertical through hole 9 is opened in the center, and when the container 6 is placed, the upper end 3 of the vertical shaft 2 passes through the through hole 9 and extends slightly upward. stand out. 1
0 is a hanging piece that prevents the container 6 from falling. A stirring spiral 11 is installed within the container 6 . The stirring spiral 11 rotates with its lower end 12 connected to the upper end 3. The stirring spiral body 11 is detachable. The stirring spiral body 11 has, on its outer periphery,
A lower feed spiral body 13 and an upper feed spiral body 14 are attached. The lower feeding spiral body 13 is formed in the upper half, and the upper feeding spiral body 14 is formed in the lower half, and an awn removing part 15 for removing the awns of the seed rice is formed therebetween.

As an example, the relationship between the lower feed spiral body 13 and the upper feed spiral body 14 is formed as follows.

Diameter of lower feed spiral body 13……R Diameter of upper feed spiral body 14……R′ Pitch of lower feed spiral body 13……P Pitch of upper feed spiral body 14……P′ R/R′≒1.2 (However, P=P') R/R'≒1.4 (However, P/P'≒1.2) In other words, when the pitches P and P' of the lower feed spiral body 13 and the upper feed spiral body 14 are formed to be the same, the upper feed spiral body The diameter R' of the upper feed spiral body 14 is made somewhat smaller, and when both diameters R are made the same, the pitch P' of the upper feed spiral body 14 is made smaller.

Further, the diameter R' of the upper feed spiral body 14 is made approximately equal to the inner diameter of the bottom wall 7. 16 is a disk.

(effect) Next, we will discuss the effect.

Since the present invention has the above-described configuration, when the lid 8 is removed and the rice seeds are put inside, and the power is supplied to the router a, the vertical shaft 2 rotates through the belt and is connected to the upper end 3 of the vertical shaft 2. The stirring spiral 11 rotates.
Therefore, the lower feed spiral body 13 lowers the unhulled rice in the container 6, the upper feed spiral body 14 raises it, and the awn removal section 15 removes the awns by grain-by-grain friction. In the above case, the upper half of the stirring spiral 11 is connected to the lower feeding spiral 13, and the lower half is connected to the upper feeding spiral 14.
Since the awn removing part 15 for removing the awns of the seed rice is formed between the lower feeding spiral body 13 and the upper feeding spiral body 14, grains are rubbed evenly in all parts. The grains are seeds without awns.

(Effects) In the conventionally known Japanese Utility Model Application Publication No. 17362/1983, a container with a larger diameter toward the top and an opening at the top is provided on the underframe, and the top end of the vertical shaft rotated by a motor is attached to the bottom of the container. The lower part of the stirring spiral is attached to the upper end of the vertical shaft, and the stirring spiral is formed into a downward feeding spiral. Furthermore, in the conventionally known Japanese Utility Model Publication No. 53-41473, the left half is formed into a right feeding spiral body, the right half is formed into a left feeding spiral body, and the seed awn is removed between the right feeding spiral body and the left feeding spiral body. A pretreatment machine for obtaining seed rice for sowing is described, which has an awn removal section formed therein. Also, JP-A-52-
Publication No. 132458 describes a wet grinding device in which a plurality of right-hand feed spiral bodies and a plurality of left-hand feed spiral bodies are provided facing each other on a horizontal axis.

However, since the product disclosed in Utility Model Application Publication No. 48-17362 has only a downward-feeding stirring spiral attached to the vertical shaft, the awn removal action is not sufficient, so even if the paddy is stirred to the extent that it is damaged, the awns cannot be removed. do not have. Actual public school 53-41473
The one in the publication has a right-handed stirring spiral and a left-handed stirring spiral attached to the horizontal shaft, so the paddy accumulates at the bottom due to its own weight, and the pressure increases as it descends, making it impossible to equalize the awn removal action. It is impossible to remove the awn without leaving a single grain behind. If there is even a small amount of paddy with awns, it will interfere with even sowing. In this respect, the method disclosed in Japanese Unexamined Patent Publication No. 52-132458 is also similar.

However, in the present invention, a container 6 is provided on the underframe 1 and has a larger diameter toward the top and is open at the top, and the upper end 3 of the vertical shaft 2 of the motor a protrudes from the bottom of the container 6. 3, the lower part of the stirring spiral 11 is detachably attached to the stirring spiral 11, and the upper half of the stirring spiral 11 is formed as a lower feeding spiral 13, and the lower half is formed as an upper feeding spiral 14, and between the lower feeding spiral 13 and the upper feeding spiral 14. In addition, since this is a pre-processing machine for obtaining seed rice for sowing, which is formed with an awn removal part 15 for removing the awns from the seed rice, (a) The awn removal action is sufficient, so there is no need to stir the rice to the extent that it damages the rice. The awn can be removed.

(b) Since the awn removal action is uniform, it is possible to remove the awns in a short time without leaving any grains behind.

C) The awn removal action is complete, and the awns can be removed in a short time without leaving any seeds behind, so sowing can be done without spotting.
