Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a deseeding of grain seeds with awns and a grain size selecting device.

(Prior Art) When seed rice for planting rice is supplied to a seeding device with awns (hair attached to the tip of the seed paddy), the seed buds interfere with the seedlings and the seeds cannot be sown accurately. The seeds were sown by removing the awns from the gazette, the Japanese Utility Model Laid-Open No. 56-146443), followed by wind-selection with Kara Minoh, followed by salt-water selection to remove the floating seed rice with a low specific gravity.

Incidentally, Japanese Utility Model Publication No. 4-2636 discloses a fruit sorting machine in which spiral rolls having spiral grooves formed on the outer peripheral surface thereof are juxtaposed and a moving groove is formed on the upper surface between the spiral rolls. There is.

Further, in Japanese Utility Model Publication No. 47-30376, for rice bran removal, a lower flow path of the supply hopper is formed, a blower port is formed on one side of the flow path, and a suction port is formed on the other side. It describes a bran removing device in which a screening net is provided between the suction ports.

(Problems to be solved by the invention) In the publicly known one, the awns after awning were suddenly hung on Kara-miso and separated by wind. However, the separation of awns by Kara-miso often produces dust. The work was hard. In addition, since there is no extreme difference in the specific gravity between the seeds and the awns, it is difficult to separate the seeds and the awns by the Kara Tsum.

The bran removing device described in Japanese Utility Model Publication No. 47-30376 is provided with a sorting net so that grains are not blown, and only the bran is blown. However, when this device is used to sort the awns, It is too long to be caught in the mesh and cannot be selected. With strong suction, even the seed pad will adhere to the sorting net.

However, if seed rice and awns are first separated by size and then removed by wind, they can be easily separated and are hygienic without dust. In addition, when the particle size selection is also performed, the particles are aligned and the seedlings can be raised.

(Means for Solving the Problems) Therefore, the present invention comprises the deseeding device 3 of the seed paddy 31 and the sorting device 16 of the seed paddy 31 deseeded by the deseeding device 3, and the sorting device 16 includes many The spiral roll 17 is formed by a group of spiral rolls 17 and a suction device 19.
