Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oscillating sorter in a threshing machine. 2. Description of the Related Art Conventionally, the opening degree (measurement) of both a Glenshaft and a Chavesh has been changed and adjusted synchronously. [0003] In such prior art,
When the sheave is closed when the flow rate is low, there is a problem that a large amount of No. 3 scattering occurs. An object of the present invention is to solve the problems of the related art and improve the sorting performance. In order to achieve this object, the present invention has taken the following technical measures. [0004] In other words, the technical means according to the present invention is to receive a treated material leaked from the handling room 1.
In the swing sorting device 5 that performs sorting processing, the swing sorting device 5
5 is a grain pan 6 and a continuous row behind the grain pan 6.
Primary grain sieve 7, chaff sheave 8, and stroller
The primary Glen Sheave.
A first sorting net 10 is provided below 7 and the chaff sheave 8,
A secondary grain sieve 11 is provided below the front of the first sorting net 10.
, The primary GlenSieve 7, the chaffy
The opening of the valve 8 and the secondary grain sheave 11 can be changed independently.
No. 1 deep-frying cylinder 1 that is configured to be free and transports the selected grains
9 is provided with a flow sensor 20, and the flow sensor 20
When detecting a state where the flow rate is large, the primary grain sieve 7,
Open the chaff sheave 8 and the secondary Glen sheave 11 on the open side.
And the angle S2 of the Glen Sheave 7 is
So that it always moves at an angle smaller than the angle S1 of the sheave 8
Rocking sorter in thresher, characterized in that configuration the
It is what it was. [0005] Therefore, according to the present invention, the granularity
Since the opening degree (opening / closing degree) of the valve and the chaff sheave can be independently changed and adjusted, when the flow rate is small, for example, only the Glen sheave is closed, and the chaff sheave is kept open. The first sorting is improved, the third scattering can be prevented, and the sorting performance is improved. Further, since the opening and closing angle of the Glen Sheave is configured to be freely changeable at an angle smaller than the opening and closing angle of the Chaff Sheave, the prolapse can be reduced from a time when the flow rate is small to a time when the flow rate is large. In addition, primary granularity
No. 1 sorting net 10 is installed below the
In the lower part of the front of this first sorting net 10, secondary granularity
The secondary grain sieve 11 is provided with one
The next Glen Sheave 7 is opened and opened
So it can guide a lot of wind from below and sort
Defects can be eliminated. An embodiment of the present invention will be described below. 1 denotes a handling room, 2 denotes a handling cylinder, 3 denotes a receiving net, and 4 denotes a dust outlet. Handling room 1
On the lower side, there is provided an oscillating sorting device 5 which receives the threshing treated material leaking from the receiving net 3 and the dusted treated material from the dust outlet 4 and sifts while swinging and rearwardly moving in the handling cylinder axial direction. Provided. The rocking and sorting apparatus 5 has a grain pan 6 and a primary grain sieve 7, a chaff sheave 8 and a straw rack 9 connected to the rear of the grain pan 6. No. 1 sorting net 1
0 and a secondary grease 11 are provided. The processed material that has leaked from the receiving net 3 and has passed through the Glen pan 6 and the primary grain sieve 7 is oscillated and transferred to the first No. 1 sorting net 10, and then subjected to the No. 1 sorting nozzle 10 for leak sorting. While being selected by the sorting wind from the pressurized Karamin 12 while being selected by wind, it is rocked and transported backward, and is dropped and discharged from the rear end. On the other hand, the waste material discharged from the exhaust port of the handling chamber 2 is directly received on the chaff sieve 8 and is sifted and swayed to the rear while being sifted. From the end of 9, it is discharged outside the machine with the sorting wind,
Further, the floating dust is sucked and discharged by the suction dust discharging fan 13. At the bottom of the sorting room, the first gutter 14
And the second gutter 15 are provided. Each of the primary grave 7, the chaff sheave 8, and the secondary grive 11 is provided with a respective one of the sheaves 7a,
8a and 11a are configured so that the opening degree (opening / closing degree or eye contact) can be changed and adjusted around the axis P of the horizontal axis.
Numerals 8 and 11 are configured such that the opening degree can be independently changed and adjusted independently by adjusting means A, A and A comprising an operating mechanism 17 using the electric motor 16 and an operating lever 18 for operating the electric motor 16. are doing. In addition, a flow sensor is provided on the first
20 and a prolapse sensor 21 are provided, and
These are connected to the respective adjusting means A, A, A via a control device. Granulation according to flow rate and amount of prolapse
The opening / closing angle S2 of the valve 7 and the opening / closing angle S1 of the chief sheave 8 are changed respectively, and the angle S2 of the grive is always controlled to be smaller than the angle S1 of the chaff sheave. are doing. Therefore, it is possible to reduce the number of prolapses from when the flow rate is low to when it is high. Further, each of the sheaves 7, 8, and 11 can be opened and closed according to the flow rate and the amount of the prolapse, and when the Glen 7 moves to the closing side, the Sheave 11 is also closed. Can be controlled to move to the side. In other words, when the flow rate is high, the amount of leakage from the starting end of the first sorting net 10 is increased by opening the grain sieve 7 to cause poor sorting. By opening 11 also, it is possible to guide a lot of wind from Karamin 12 and to solve the above-mentioned problems, to reduce the number of splinters and reduce the number 3 scattering. Another embodiment will be described with reference to FIGS. 6 and 7. FIG. 22 is a sheave plate, 23 is a shelf side plate, 24 is an interlocking plate, 2
5 is a sheave operating arm, and 26 is a body side plate. The sheave operating wire 27 is routed rearward from the front of the fuselage, and the terminal end of the wire 27 is connected to the sheave operating arm 25. That is, the wire 27 is pulled in the direction in which the sheave plate 22 is closed, and is pulled by the spring 28 in the direction in which the sheave plate 22 is opened. A wire cover 30 is provided in the routing hole 29 from the inside of the fuselage side plate 26 to the outside so that the wire cover 30 is inclined so as to close the passage hole 29 of the fuselage side plate 26. The wire cover 30 is formed with a sloped guide portion 30a to prevent the outside of the paddy and straw chips from the sorting room from scattering. In other words, the flow of paddy and straw waste is indicated by the arrow (a). The guide is configured to be (b). Conventionally, as shown in FIG. 8, the wire is routed forward from the rear of the fuselage as opposed to the present invention. Straw chips were scattered outside the machine as indicated by the arrow (c).
