Description

[Detailed description of the invention] Industrial applications The present invention relates to a test hulling and selecting machine.

Conventional technology In modern rice centers, in order to streamline the work of importing unhulled rice, which is concentrated temporarily, the work equipment from the receiving hopper to the rough sorting machine, automatic moisture meter, weighing instrument, sorting conveyor, and receiving tank is used. Each of these tasks has been automated, and the various data obtained during the process, such as storing the variety and farm card data and printing them on processing slips, are now being centrally performed using a computer. In this case, before the imported unhulled rice is put into the receiving tank, the inspection department extracts a sample of the unhulled rice and obtains the weight of the sized brown rice for the received unhulled rice, which should be included in the calculation of moisture content and yield. , it is necessary to calculate the appropriate payment price based on that.

For example, Japanese Utility Model Application Publication No. 56-58425 is known as an automatic self-inspection device for grains that streamlines the administrative functions of the rice center mentioned above. Use hoppa,
The lower part of the hulling section is equipped with a thrower switching valve for switching between the return hopper and the sorting section for the next process, and the sorting section has a discharge valve for transporting the sized brown rice and waste rice to the measuring section for the next process. In addition, the weighing section is equipped with a weighing unit for weighing the sorted brown rice and waste rice that have been sorted in the sorting section, but in this case, the unhulled rice for which the weight of the sample paddy is measured Since it is not equipped with a weighing machine, even if it is possible to measure the ratio of sized brown rice and scrap rice, it is not possible to determine the proportion of sized brown rice and scrap rice to the sample paddy. However, there were some troubles such as the need for separate weighing pads for weighing grained brown rice and scraped rice.

In order to deal with this, the applicant connected the rice weighing device connected to the raw material paddy input hopper to the test hulling machine via the discharge gutter and the grain lifting machine, and A sorting machine consisting of a porous-walled sorting tube is installed in the machine, and a weighing device for grain-sized brown rice, immature rice, and crushed grains is installed below the sorting machine, and the test huller, sorting machine, and both weighing devices are installed in the machine frame.
