Description

[Detailed explanation of the idea] The present invention relates to a test huller.

In other words, in a test huller that performs double shearing for rice quality inspection and yield investigation, it can be operated semi-automatically without making any mistakes in the double shearing operation, and it reliably performs double shearing properly. The purpose of this invention is to provide a method that enables the husking of rice grains to be carried out suitably.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a cross-sectional view of the entire structure, and above the removing chamber 8 having both removing rolls 1, 1, there is a first tank 2 and a second tank 3 whose respective lower openings look above both removing rolls 1, 1. are installed in parallel, and at the bottom of the first tank 2 there is a sensor S that detects when there is no paddy left.
The lower openings of both tanks 2 and 3 have corresponding openings 9 and 10, respectively, and are equipped with shutters A that can close the other when one is opened.

Grain flow plates 12 and 13 are sequentially provided diagonally below the reflective plate 11 below the chamber escape 8, and a sorting shelf 4 is diagonally provided below the lower grain flow board 13. Sorting shelf 4 to distribute sorting wind to
An axial fan 14 is installed above the slope, and a cyclone 15 is installed on the discharge side of the axial fan 14 to drop rice hulls and the like from below.

A reception port 16 is opened in the middle of the sorting shelf 4 located below the grain board 13, and a spiral conveyor 18 is mounted in a gutter 17 that is connected to the bottom of the reception port 16. The spiral conveyor 18
A grain lifting machine 6, which is a thrower, is installed in series at the terminal end of the
The upper jump side of the grain lifting machine 6 is installed so as to communicate with the upper part of the second tank 3, and the receiving port 1 is connected to the upper part of the second tank 3.
A final takeout port 5 is installed on the lower sloped side of the sorting shelf 4, which is the sloped downward side from the top of the sorting shelf 6, and is installed so that grains can be received by a receiving box 19 below the takeout port 5. and configure.

Reference numeral 7 designates a switching valve that can be rotated around a support shaft 20. When the switching valve 7 is rotated onto the receiving port 16 and is in a closed state, the grains on the sorting shelf 4 flow to the takeout port 5 side, and the switching valve 7 is turned up. The upper end of the suction rod 28 that moves in and out of the solenoid 27 at the lower side The support shaft 20 and the tip of the integrated arm 29 are connected by an interlocking rod 30, and while the sensor S is in contact with the paddy, the solenoid 17 is energized and the switching valve 7 closes the outlet 5 side. When the sensor S detects that there is no paddy left, the solenoid 27 is de-energized after a certain period of time by the timer T, and the switching valve 7 is moved to the receiving port 16 side by the tensile force of a spring (not shown). It is installed and configured so as to rotate and close the receiving port 16.

Therefore, during the work, the lower part of the first tank 2 is closed by the shutter A and a certain amount of paddy is put into the first tank 2, but in this state,
The sensor S is in contact with the paddy, and the switching valve 7 is rotated in a direction to close the outlet 5 side, resulting in the state shown in FIG. 1.

As shown in FIG. 2, the operation starts when the shutter A is operated to align the openings 9, and the paddy in the first tank 2 is removed by both removal rolls 1, 1.
When it falls onto the lower sorting shelf 4, the axial flow fan 14
At the same time, the rice hulls are suctioned and sent to the cyclone 15 side, and the selected removed rice falls from the receiving port 16 into the gutter 17, is conveyed to the spiral conveyor 18, and is sent to the grain lifting machine 6. It is placed in the second tank 3.

In this way, when the first tank 2 runs out of paddy, the sensor S detects it and the timer T turns off the power to the solenoid 27 after a certain period of time, and then, as shown by the imaginary line in FIG. Further, as shown in FIG. 3, the switching valve 7 is rotated so as to close the receiving port 16, but all of the removed rice falls into the receiving port 16 within a certain period of time determined by the timer T.

Next, as shown in FIG. 4, when the shutter A is operated so that the opening 10 matches the lower part of the second tank 3, the rice in the second tank 3 is removed twice by the removal rolls 1 and 1. The removed rice that has been sheared and air-sorted on the sorting shelf 4 flows directly to the take-out port 5 side and is received in the receiving box 19.

By observing the removal of rice, it is possible to inspect the quality of rice and investigate the yield from a fixed amount of rice that has been removed twice.

In this way, the present invention has a first tank and a second tank each having a shutter at the bottom above both de-rolls, and a sorting shelf below both de-rolls has a final take-out port side and a second tank having a shutter at the bottom. A switching valve is installed in the grain lifting machine that communicates with the second tank, and a sensor installed in the first tank allows the switching operation to be performed using the switching valve. When conducting a test by putting a certain amount of paddy into the first tank, when the paddy in the first tank runs out, the changeover valve can be operated to take out the paddy to the outlet side in the next two-degree shear condition. The change-over valve can be automatically switched so that the rice can be properly operated semi-automatically without making any mistakes in the double shear operation, and the rice can be reliably and successfully husked with the double shear. This method has the advantage that tests for rice quality inspection and yield investigation can be conducted well and can be carried out suitably.
