Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is a method of collecting and mixing grains brought into a rice center by each farmer, by sampling a portion of each grain by each farmer. The present invention relates to a finished rice testing device that tests the quality (for example, grade) of grains (finished rice) by collecting them, drying them, and removing them.

[Prior art and problems to be solved by the invention]

In conventional finished rice testing devices such as those disclosed in Japanese Utility Model Application Publication No. 56-58425, after sorting into sized grains, small grains, etc. and inspecting the quality of the sized grains, the rice is manually packed into designated bags and stored. Ta.

Therefore, in a work format where continuous verification is required, time is lost in the verification work due to the above-mentioned bagging work being stagnant.

[Means for Solving the Problems] The present invention aims to solve the above-mentioned drawbacks, and includes a shedding device 1 for shedding grains, and a grain sorting device for sorting the sheathed grains into regular grains and small grains. machine 2, a weighing machine 3 that weighs the sorted and collected grains, a bagging machine 4 that separates the grains into units and bags them continuously, and the weighed sorted grains and small grains. The finished rice verification device has a structure that includes a conveyance mechanism that separately feeds the rice and the rice to the bagging machine 4.

[Operation and effect of the invention]

A small sample of some of the grains brought in by a certain farmer is decoupled in the decoupling device 1, and sent to the grain sorter 2, where it is sorted into predetermined sizes and small grains while being subjected to air sorting on the way. In other words, it is separated and sorted into immature rice such as green rice, rice cake, etc. These are received and weighed separately by a weighing device 3, and sequentially sent to a bagging machine 4 by a conveyance mechanism such as a thrower 20. In this case, the sorted grains and small grains are continuously bagged separately, so there is no need for inspectors to measure and bag them each time, improving work efficiency. Since it can be stuffed, it is easy to transport and store.

〔Example〕

An embodiment of this invention will be described based on the drawings.

First, the configuration will be explained. The device 1 is composed of a pair of roll removal units rotating in different directions (arrow directions), and a supply hopper 5 communicating with the upper side is installed. A dust exhaust fan 6 is installed on the side of the dehulling device 1 for wind-selecting the dehulled grains and discharging the paddy grains to the outside of the machine. The supply hopper 5 communicates with a charging hopper 8 via a thrower 7, and the charging hopper 8 communicates with a charging hopper 12 having an on-off valve 11 via a sample receiver 9 attached to a weighing scale 10. is connected to. The weighing scale 10 suspends a support rod supporting the sample receptacle 9 with a spring, converts the displacement of the sinking support rod into an electric quantity, and digitally displays the weight of the sample. 13 is an on-off valve for tensioning.

Below the removal device 1, two grain sorters 2 are installed side by side on the left and right, and an intermediate hopper 14 that communicates with the lower intake of the thrower 7 is installed in the center. It is switchably connected to either one of the two grain sorters 2 or the intermediate hopper 14 via a switch. The discharge port of the intermediate hopper 14 is equipped with a return on-off valve 16, and the on-off valve 16 and the switching device 15 are linked so that when the on-off valve 6 is closed, the switching device 15 is connected to any grain sorter 2. It consists of

The grain sorter 2 rotates a polygonal sorting cylinder made of a perforated plate, and the grains fed into the cylinder after deairing and sorting are sorted into sized grains and small grains (immature rice, gruel, waste grains, etc.). It has the same form as the thing. An on-off valve 17 opens and closes each discharge port opened at the bottom of each grain sorter 2,
18, and a grain collection box 19 of the discharge measuring device 3 (same structure as the loading measuring device 10) is visible below the on-off valves 17, 18. The grain collection box 19 is provided with a shutter 26 and communicated with the bagging machine 4 via a discharge thrower 20 as a conveyance mechanism.

The bagging machine 4 presses a hollow cylindrical thin-walled bag material 21 formed in a roll shape, a cutter part 22 that makes a cut in the side of the bag material 21, and the bag material after bagging to form a bag shape. It is composed of a sealing part 23 for printing, a printing part 24 for printing the date, measurement calculation results, etc. on the outside of the bag after sealing, and a series of these operations is carried out by the control equipment built in the control box 25 (for example, Sequence control is performed by a microcomputer (not shown).

Note that, like the bagging machine 4, the process from the input of the sample to the bagging operation by the bagging machine 4 is automatically controlled by sequence control, but this control circuit will be omitted. .

Next, to explain its operation, a small amount (about 500 g) of grain, for example, from a certain farmer brought into the rice center is taken out as a sample and supplied to the input hopper 12, and when the on-off valve 11 is opened, the sample receiver 9
The weight is measured by the tensioning scale 10. The measured grains are passed through the tensioning on-off valve 13
When the grain is opened, the grain is fried to the supply hopper 5 via the loading hopper 8 and the thrower 7, and then the grain is transferred to one of the grain sorters 2 (in the embodiment, the left side During this time, the grains are also air-sorted by a dust exhaust fan 6 and discharged outside the machine, so that only the selected grains are fed into the grain sorter 2. Then, the rotating particle sorter 2 is also subjected to the shape sorting action, and the small particles fall from the screen and fall into the opening/closing valve 1.
7, and when a predetermined sorting time has elapsed, the on-off valve 17 opens and the grains flow into the collection box 19 and pass through the weighing machine 3.
It is measured in Then the shutter opens and thrower 2
After the grains are taken over to 0 and fried and fed into the notch of the bag material 21, they are crimped at the sealing part 23 and sealed inside the bag, and the printing part 24 prints the calculation results of small grains, date, farmer's name, variety, etc. on the outside of the bag. It will be printed. Next, the sorted grains discharged from the grain sorter 2 by an appropriate discharge mechanism are subjected to the same operation as the small grains, and are sealed in the bag following the small grains and printed on the outside of the bag. When this farmer's work is finished, if the sample from another farmer is fed into the input hopper 12 in the same way as the previous farmer, the same work as above will be carried out, and the small grains will be continuously collected following the bagging by the previous farmer.
The grains are sorted and packaged separately.
