Description

[Detailed description of the invention] The present invention relates to an oscillating grain sorter.

The rice husk is removed from the defloated mixture of brown rice, hulled rice, and rice husks by supplying the unhulled rice to the dehulling roll of the defloating device, and the rice husk is removed by a rice husk wind sorter installed in the dehulling roll machine, resulting in mixed grains of brown rice and unhulled rice. After being fed to the oscillating sorting board of the oscillating sorting device by the grain lifting machine,
The mixed grains are shaken up in synchronization with the shaking of the sorting disk, and when the mixed grains supplied onto the sorting disk are shaken up and tilted, unhulled rice with a small specific gravity and a high coefficient of friction floats up, The brown rice with a small coefficient of friction sinks and flows and is concentrated on the lower side of the sorting plate, and the mixed grains flow in the interval between the paddy rice layer and the brown rice layer, and are discharged to one side of the sorting plate, and the discharged mixed grains are The paddy deweighing unit joins the rice grain hoisting machine through the flow gutter and returns to the sorting board, where the brown rice is flowed to an appropriate location and the unhulled rice is returned from the lower side of the sorting board to the paddy rice supply section of the defloating device. Sorting devices are already known.

This paddy defloating and sorting device solves the major defects of rice grain defloating machines that have existed for many years by rationalizing the sorting board. If the clogs are not cleaned, the flow of paddy brown rice will stagnate, resulting in a large amount of work that will not be done.There will also be the hassle of having to replace nets with different mesh sizes depending on the paddy variety, and depending on the paddy variety, it may not be possible to sort out any silk. However, with the above-mentioned oscillating sorting machine, it is possible to sort high-purity rice, regardless of its quality, by simply adjusting its inclination angle. This is easy to do, and it is extremely convenient since it is integrally formed on the breakaway aircraft. However, in a conventional swing sorter in which the sorting board of this type of paddy deweighing and sorting device is tilted so as to be swingable, the supply section for mixed grains of paddy and brown rice is installed at the inclined upper part of the sorting board. As a result, mixed grains of paddy and brown rice must be fed to the sorting board from a high place, which is difficult. The disadvantage is that the overall height of the device is large and it lacks stability.

In order to deal with this drawback, a swing sorting machine was proposed as Utility Model Publication No. 42-5973 and Utility Model Publication No. 39-1274, in which a feed section was provided on the swinging side of a sorting board tilted so as to be swingable. Ta.

However, these systems simply have a supply section on the swinging side of a freely swingable slanted sorting board, so the grains fed from the supply section onto the sorting board are processed by the swinging of the sorting board. Since the grains are spread over the entire board, a wide area where grains are not present occurs on the feed section side on the swinging side of the sorting board, resulting in poor sorting efficiency.

The present invention eliminates the above-mentioned drawbacks by fixing a vibrating conveyor whose starting machine faces the supply section provided on the swinging side of a swingable inclined sorting board to the sorting board so as to face the swinging side of the sorting board. Compared to a system in which the feed section is simply provided on the swinging side of a tilting sorting board that can freely swing, the grain-free area that occurs on the supply side of the swinging side of the sorting board is made smaller, and the sorting board surface can be used more widely. The purpose of the present invention is to provide an oscillating grain sorting machine that increases sorting efficiency. In order to achieve this object, the present invention provides a swinging sorter in which a sorting board is tilted so as to be swingable, and a supply section is provided on the swinging side of the sorting board, with a starting end facing the supply section. The present invention is characterized in that the vibrating conveyor is fixed to the sorting board so as to face the shaking side of the sorting board.

To explain the present invention with reference to an embodiment diagram, a rocking sorting board 1, IA, IB with a rough surface is suspended on support legs 2, 3 at an inclination angle Q, and is tilted to the same side by a shaft 4, which is larger than the inclination angle Q. The vibrating conveyor 6 is oscillated at an inclination angle of 8, and this inclination angle Q can be adjusted. , 6A, and 6B are fixed to a sorting board facing the shaking side to constitute a swinging shell sorting machine.

The oscillating grain sorting machine has supply parts 5, 5A, and 5B for mixed grains of paddy and brown rice formed at the lower part of the sorting board 1, IA, and IB with a low slope, and the oscillating direction L and day are perpendicular to each other. Each side has a discharge section 7, 7A, 7B.

V supplied to the descending table parts 5, 5A, 58 of sorting board 1, IA, IB
The supplied namiai grains pass through the vibrating conveyors 6, 6A, and 6B fixed to the sorting plates 1, IA, and IB, respectively.
It is fed to the surface of the IB and shaken up, and concentrates the brown rice on the high side, and concentrates the unhulled rice on the low side L, and flows the mixed grains between them. Side 7, 7A
, 7B flows and is discharged, brown rice is discharged from the high side,
The unhulled rice is sent to a deflotation machine, and the mixed grains discharged from the middle M on one side 7, 7A, 78 are returned again to the joint portions 5, 5A, 58 of the sorting plates 1, IA, IB.

As described above, the present invention provides an oscillating sorting machine in which a sorting board is provided tilted so as to be swingable, and a supply section is provided on the swinging side of the sorting board, with the starting end facing the supply section. The present invention is characterized in that a vibrating conveyor is fixed to the sorting board so as to face the shaking side of the sorting board, so that the mixed grains of paddy and brown rice are transferred from a low place to a special transport means other than the sorting machine. It can be carried out without using a vibration conveyor, the combination work is easy, and the height of the whole device can be lowered to ensure stability. Because of the rapid movement to the raising side, compared to a tilt sorting board that is simply swingable and has a connecting part on the swinging side, it is possible to reduce the amount of grain absent on the feed section on the swinging side of the sorting board. By making it smaller and using a wider sorting board surface, sorting efficiency can be increased.
