Description

[Detailed Description of the Invention] The present invention relates to an apparatus for separating and sorting straw waste, etc. in a coarse phase separator.

In other words, in a coarse grain sorting machine that is configured with a swingable separate body equipped with an inclined sorting plate that sorts out paddy mixed with straw waste, etc., the paddy is separated from the sorting plate that roughly sorts the paddy. While feeding the paddy in such a way that it floats, it is possible to use suction air to suck up light items such as straw waste and twigs and separate them well, and the sorting board can perform full-scale and reliable sorting. The present invention is intended to provide a method that enables coarse phase selection with high accuracy, and has a simple structure so that it can be carried out suitably.

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

The drawing shows a cross-sectional view of the entire rough sorter, A is a swinging sorter,
A plurality of swinging supports 14 are provided so as to swing at a constant swinging angle.
, 14, and one end of a swinging arm 7 that fits into an eccentric wheel 6 rotated by a motor 5 is connected to one swinging support rod 14 via a rotating pin 8. There is a sorting plate 1 made of perforated iron plate that tilts in accordance with the swinging direction.
At the same time, below the sorting plate 1, a grain flow board 9 which is also inclined is also installed, and below the terminal end of the grain flow board 9, a downward flow is provided at the lower end of the grain flow board 9. An outlet 10 is formed, and a discharge port 11 is formed on the end extension side of the sorting plate 1.

Further, a funnel portion 12 is formed at one upper end of the upper case a formed above the 11th inclined side of the oscillating sorting body A,
Below the funnel part 12, in the upper case a, there is a swinging separation whose one end side extends below the funnel part 12 and whose free end side end 2a extends above the inclined upper side plate part 1a of the sorting plate 1. Board 2
is installed in an inclined manner, and the structure is such that the oscillating separation plate 2, which oscillates together with the oscillating sorting body A, can feed the rice to the end 2a side while floating the rice mixed with straw waste etc. do.

Reference numeral 4 denotes a hopper, which has a feeding roller 15 installed therein and is fixed to the machine cover 13.The hopper 4 is installed so that the lower outlet 4a of the hopper 4 faces above the funnel portion 12 of the swinging sorter A. A mounting gutter 17 equipped with a spiral conveyor 16 is installed below the outlet 10 of the oscillating sorting body A.

Further, a suction dust extractor B is installed above the fuselage cover 13, and has a dust exhaust pipe 18 connected thereto and a blade wheel 19 installed therein, and a suction air path extending from a suction port 20 of the suction dust extractor B 3 is installed through the opening 21 of the upper case a so that the front end 3a approaches the end 2a of the swing separation plate 2. A winding path 3b is formed, and a second outlet 22 is installed at the end of the winding path 3b.

When the paddy harvested by the harvester and mixed with stems, straw waste, etc. is supplied to the hopper 4, the entire oscillating sorting body A is oscillated by the drive of the eccentric wheel 6, and the inside of the hopper 4 is The paddy etc. fed out by the feeding roller 15 are discharged into the funnel part 12 through the outlet 4a, and when they fall onto one end of the swinging separation plate 2, they are fed in the direction of arrow A by the swinging separation plate 2. Light straw, branches, etc. are floated, and are sorted out by the suction air that extends from suction air path 3 to t9 as shown by the dotted arrow opening, and such waste is discharged to the fabric. At this time, the second object sucked into the suction air path 3 falls into the second outlet 22 and is taken out due to the difference in specific gravity.

The rice grains, etc. from which straw waste, branches, etc. have been removed are moved from the end 2a of the swing separating plate 2 to the lower plate part 1a as shown by the arrow.
1:=, and as it continues to flow down on the oscillating sorting plate 1, the regular paddy is sorted and dropped to the lower grain board 9, and then taken out from the outlet 10 and falls into the gutter 17. On the other hand, straw and the like that do not leak through the sorting plate 1 flow directly from the sorting plate 1 to the discharge port 11 and are taken out.

As described above, the present invention provides a coarse grain separator configured by swingably installing a separate rocking body equipped with an inclined sorting plate for sorting out rice mixed with straw waste, etc. A swinging separation plate is installed at the -L portion of the swinging sorter on the side to float and transfer the rice supplied from a hopper, etc., and the end of the suction air path is installed on the delivery side of the swinging separation plate. Because the paddy is fed to the sorting board that roughly sorts the paddy, the swinging separation plate is used to float the paddy, etc., and feed it to remove the light straw that gets mixed into the paddy. The suction air from the suction air duct can be used to sort and suck out waste, twigs, etc. in advance, and therefore the sorting board can accurately pick out paddy, etc. from which straw waste, twigs, etc. have been removed. It has the advantage of being able to perform rough selection of hard grains without causing clogging, and has a simple structure and can be carried out appropriately.
