Description

Detailed Description of the Invention "Industrial Application Field" The present invention is equipped with a rotary sorting tube that is continuously rotated in one direction to separate grained purple brown rice and paddy after hulling, which separates brown rice from grains after hulling. The present invention relates to a grain sorting device that sorts grains by N1 minutes.

"Conventional technology" Is there any sorting accuracy in this type of equipment? As a means to keep it constant, what is the deweighing rate, the rotation speed of the sorting tube, the valve angle in the brown rice receiving trough, or the supply? I went by adjusting.

[Problems to be solved by the invention] However, in cases where there is a large difference in the sand grain layer distributed in the sorting cylinder due to differences in the degree of dryness of grains, varieties, and crops, this problem may be considered. Even with the above methods, there was a drawback that it could not be adequately addressed.

"Problem? Means to solve the problem" Therefore, in the present invention 191, 4ii is installed in the middle part of the sorting tube at 9 and 9 in the way of the sorting tube, and the grain amount sensor 4ii detects the sorted grain amount in the sorting tube, and the +it+2 sensor detects the amount of grains. Sorting cylinder σ) based on 1st shift
The inclination angle is variably controlled to maintain a constant distribution of 1 cm of the grain layer inside the cylinder.

According to the present invention, even if the distribution of grains in the sorting tube changes due to differences in variety or crop, the grain layer in the standard shape is always maintained. Make the powder layer (
4) What is the inclination angle of the sorting tube? How can it be controlled automatically and under these conditions to ensure that there is always a stable grain layer and its sorting accuracy? This is intended to improve work efficiency.

In this embodiment, the configuration is as shown in gcl above.
The grains (brown rice and paddy) that were milled and weighed on the ff roll +31141 are sorted and then fed to the upper sorting cylinder 1211 through the mixed rice thrower Q9+, where they are recycled during the rotation of the k and B parts 12+1. (2+a) The brown rice that is inserted into the paddy is lost to the receiving gutter due to the specific gravity ψ or slippage with the paddy, or the difference in f or size. Only good quality brown rice with no paddy mixed in is transferred to the receiving gutter 7'1 (321) and transported out of the machine via the brown rice gutter +341 and the brown rice thrower (lslh).

The opening/closing control or the inclination angle control of the first shadow tube 121+ is performed to stably maintain the grain at the standard level.The following 11 production theory 1 is based on the flow of 1,000 yards in Figure 5.

When the l-on operation is performed, if the sorting machine casing is in a tilted condition, the front scissor decoy will be driven to clean the machine casing and adjust the sorting cylinder f2111221 horizontally by 7"l. When the #1 switch 0 is on, grains are supplied into the lower sorting tube 211.If'k'The first sensor 1531 senses a certain amount of grains.JWhen this first switch ω is turned on,
The fla% motor (the partner drives one step, and the machine casing is tilted in the direction of the solid arrow in Fig. 3 so that the sorting tube 21 + I221 is bent. As a result, the flow angle in the sorting tube 121) is the same as the initial one. It is larger than that of the shaped cap, and does not promote the flow of grains toward the line gutter, which is the end of this feed.

Now, the second sensor q) is in operation due to the 1FIP changeover switch, and the sand grains are flowing down f4't1.
Is Senza 641 a constant grain amount? When sensing, the iH tilting operation stops, and after that, based on the change in the resistance value of the potentiometer 0 of the sensor, the iL2 motor (61) is adjusted to the appropriate side I11 + tongue supply valve (51 opening/closing and sorting tube). e2

Is the standard constant grain amount set in the large grain amount and small grain amount? When sensing, the motor (61 sensitive) (481) is designed to detect whether the second sensor (goods) is below the standard amount of grain?
The first motor F61 is driven every step until the amount of grains detected at the position of the sensor 154) reaches the reference level, and the supply valve 51r is retracted step by step to supply grains to the sorting cylinder θ11. We will definitely try to increase the amount.

- When the second sensor detects more than the basic estimated amount of grains, the sorting tube 1211' (((force) is tilted backwards, that is, in the direction of returning to the water mop shape as opposed to the above-mentioned melting, the motor H81hl is rotated every step to sort the grains. The flow rate (movement) of grains in the cylinder 12+1 is reduced to reduce the difference in the grain layers of the inner metal body, and the situation in which grains accumulate at the feed end VCfi is eliminated. let

In each step, rtω1 is applied to feed 51 grains in stages to reduce the amount of grains supplied to the red grain.

In this way, in Example B, when the amount of grains supplied to the sorting tube 1211 is small, the sorting tube I211 is tilted? Is the speed of grain movement within the ar'ull adjusted to a steep angle?
At the same time, when the thickness of the grain layer (l) is below the standard, the amount of grain supplied is increased to maintain the stability of the entire grain layer. - On the contrary, when there is a large grain supply, sorting 1i! j slope of i2+1? Adjust to a gentler angle to reduce the difference r in the entire grain layer, and when the thickness of the grain layer (grain amount) is above the standard, reduce the grain amount to reduce the difference r in the entire grain layer.

Control is performed so that the grain layer from the inlet to the outlet 1 in the grain 21 is always kept constant.

In the embodiment described in GI, the third mk sensor (55a) and the switch (58a) are installed in the rice grain type 1311, although the configuration is such that the third sensor (mk) is provided at the end of the feed in the four sorting section 121). 'z may be provided.

"Effects of the Invention" As is clear from the above embodiments, the present invention has a structure equipped with a rotary sorting tube 121+i that continuously rotates in one direction and separates grain grain brown rice and paddy after hulling. Grain quantity sensor l5 that detects sorted grain #grapes in sorting section 121)
41 units are installed approximately in the center of the sorting tube 121+, and the tilt horn of the sorting tube 121) is variably controlled based on the detection start of the i-ro1 sensor 154). Since the distribution grain layer in the Jt column 121+ is maintained constant, even if the distribution grain layer in the sorting cylinder 1211 changes due to the persimmon type and crop type, etc. The inclination angle kl]ωth RIVζ of the first sorting point I211 is varied to adjust C' to an appropriate standard bag, and as a result, the grain layer during operation is always stable regardless of the kneading conditions. It has remarkable effects such as increasing the sorting accuracy and improving the work efficiency.
