Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a test hulling and selecting machine.

Conventionally, in communal drying facilities, etc., the moisture content of raw paddy supplied by each farmer is measured, and the weight of raw paddy, normal brown rice, immature rice, etc. I was calculating how much normal brown rice I could get. However, regarding the grain split ratio of rice grains,
The shell-splitting grain detector that detects this was not suitable for installation in the flow process, and the shell-splitting ratio could not be easily calculated, so not much consideration was given to this. Ta. However, even if paddy or brown rice looks normal at first glance, if it has body splitting, it will eventually turn into broken rice during the milling process, making it unsuitable for rice consumption. There were problems in evaluating each farmer's raw paddy.

The purpose of the present invention is to solve the above-mentioned problems, and in a communal drying facility, etc., test paddy (dried paddy) is collected from unhulled rice supplied by each farmer, and the total weight of the paddy and the body split are measured. Highly accurate self-verification was conducted by ensuring the weight of unripe rice and brown rice with the same grain ratio, moisture content, and same sorting rate, and the automation of the integrated process of hulling, moisture measurement, sorting, and weighing and splitting detection was completed. The aim is to develop and provide a device that streamlines the self-inspection work of received paddy rice.

The present invention will be explained with reference to embodiment figures. Dry paddy put into the raw paddy grain hopper 2 installed on the side of the box-shaped machine 1 is fried by the thrower 3 and is also raised by the automatic switching valve 4 installed in the flow path. The water is supplied to an automatic moisture measuring device 5. The measuring device 5 measures the moisture content of the grains, and the grains flow down from the outlet 6 to the paddy weighing device 7 located at the bottom, and the weight of the grains is measured. The weighed paddy is again fried by the thrower 3, and is supplied by flowing down to the supply hopper 8 on the upper part of the machine body 1 by the downward movement of the switching valve 4. A test huller 11 is connected to the lower part of the hopper 5, in which two derolling machines 9 and 10 made of hard rubber are mounted on a shaft, and the rolls 9 and 10 are disposed opposite to each other with a slight gap between them. The speed of each roll is made different from each other. Therefore, the paddy supplied to the upper supply hopper 8 flows down to the huller 11 due to the vibration action of the vibration device 12, and while passing through the gap between the rolls of the huller 11, it is separated from the rolls. It is removed by the friction of The threshed grains discharged from the huller 11 fall together with the rice grains, and are wind-selected in the wind sorting section 12 on the way, and light rice grains are discharged out of the machine by the exhaust fan 13 in the comparative example.

On the other hand, the sloughed grains are supplied to a grain sorter 14 consisting of a porous-wall sorting cylinder at the bottom, and as the rotary cylinder rotates, immature rice and broken rice fall from the porous wall surface and are separated and supplied to a rice grain scale 15. , the measuring instrument 1
The unripe rice etc. weighed by 5 is taken out of the machine by a discharge thrower 16. When the weighing of the immature rice is finished, the sized unpolished rice remaining in the porous wall sorting cylinder 15 is supplied to the weighing device 15 and the brown rice is weighed, and the bottom of the weighing device 15 opens and flows into the thrower 16. A portion of the brown rice is supplied to the split grain detector 17 by the thrower 16, the split grain ratio is detected, and the grain is taken out of the machine via the sample collection section 18 at the lower part. In the grain flow process, the total weight of the test dried paddy, moisture content, weight of sized brown rice, weight of unripe rice, and split grain ratio are all measured, and sample grains are collected. Note 1
9 is a grain detection sensor that sends a signal to the automatic switching valve to open and close it.

Next, the automatic moisture measuring device 5 has a supply port 2 at the top.
0, and a conveyor gutter 22 equipped with a vibration device is provided on the upper side of the inside of the machine frame 21 with a discharge port 6 provided at the lower part, and a measuring container 23 is provided at the bottom of the conveyor gutter 22, which is connected to a weighing device 24 on the side. Connected by a rod and a spring scale, a moisture sensor 25 is provided on the inner wall surface of the container 23, and an automatic discharge valve 26 is provided at the bottom of the container 23, so that the rice grains whose moisture content has been measured are automatically discharged. It has been done. Therefore, the paddy flowing down from the supply port 20 is transferred to the measuring container 2 by the vibration of the conveying gutter 22.
3 to form a paddy grain layer of a predetermined capacity with the upper part having an angle of repose, and the overflowing paddy grains flow down from the discharge port 6 to the paddy measuring device 7 at the lower part. And measurement container 24
In this method, the water content of the dried rice is measured, and the measured value is density-corrected based on the weight value measured at a predetermined capacity, so that the water content can be measured with high accuracy.

Next, the split grain detector 7 is provided with a hopper section 27 at the upper part, and supplies a part of the sized brown rice by flowing down to the vibrating conveyance gutter 28 at the lower part, and the conveyor gutter 28
The brown rice flows down one grain at a time into the downflow gutter 29 due to its vibration, and the light source 31 irradiates the brown rice passing through the light intensity detection unit 30 provided in the downflow gutter 29, and the transmitted light from both sides of the rice grains is 1. Pair of light receiving elements 32A, 32
The light is received by B. If the detected rice grain has a shell crack, there will be a difference in brightness between the cracked part, so the split grain is detected based on the difference in the amount of light received by the light-receiving elements 32A and 32B, and the entire detected grain is detected. Accurate shell splitting ratio can be measured by comparing with the number of grains. Note that 33 is a switching valve for allowing a portion of the sized brown rice to flow into the split grain detector 17 from the flow tube of the thrower 16. In addition, when installing a split grain detector in the flow process of unhulled rice, an automatic moisture meter 5
It is sufficient to collect a portion of the paddy that is transferred from the automatic switching valve 4 to the automatic moisture measuring device 5 attached to the automatic switching valve 4.

In addition, the flow process of unhulled rice or brown rice in the present invention means the entire process including the supply process of sample unhulled rice and the discharging process of brown rice before and after the flow process.

In this way, the test huller selection machine of the present invention is
The raw material paddy, which is weighed using a rice scale, is hulled using a huller, sorted using a grain sorter, and separated into immature rice and grained brown rice, and further processed using a rice grain scale. In the device for measuring the weight of immature rice and grained brown rice, a split grain detector was installed in the flow process of the unhulled rice or brown rice, so test paddy (dried paddy) was collected from the unhulled rice supplied by each farmer. Highly accurate self-verification can be carried out by securing the total weight of the paddy, moisture content, split grain ratio, and weight of unripe rice and brown rice based on the same sorting rate.
It is possible to complete the automation of the integrated process of body split detection, sorting, and weighing, and has the effect of streamlining the self-inspection work of received paddy rice.
