[Problems to be solved by the device]

 However, the suction-and-dust type thresher of the configuration disclosed in the above-mentioned publication also discharges the untreated material sent from the handling room to the outside of the machine after threshing treatment in the processing chamber. Since the dust is sucked and discharged from the dust chamber, the suction and dust fan installed in the dust chamber is burdened, which affects the suction and discharge of dust after sorting the handled products. It was devised with the aim of preventing any adverse effects and eventually improving the sorting condition of the second re-sorting as a second product so as not to put an unnecessary burden on the suction dust removal fan.

[0004]

[Means for Solving the Problems]

 Therefore, in order to achieve the above object, the present invention configures a swinging sorting body extending from the lower side of the handling chamber toward the dust collecting chamber and a sorting air passage to swing and displace the load from the handling chamber. It is a suction and dust type that sorts by using both of the selection operations and suctions the sorted dust from the dust chamber, and a treatment chamber for processing unprocessed substances sent from the treatment chamber is installed side by side in the treatment chamber. At the same time, the leaked material from the processing chamber is supplied to the rocking sorting body for sorting, and the end side of the processing chamber is opened to the outside of the machine.

[0005]

[Action]

 With this structure, the threshing action in the handling room falls on the rocking sorting body, and the rocking action of this rocking sorting body and the wind selection of the sorting wind that blows through the sorting air duct. Sorted by the action, the No. 1 dropped into the No. 1 trough and taken out of the machine, and the No. 2 was collected in the No. 2 trough and returned to the rocking sorter, etc., and then re-sorted, Dust is sucked and discharged from the dust chamber, and unprocessed substances sent out from the handling chamber are processed in the processing chamber, and the leaked substances are supplied to the rocking sorter for sorting and leaking. Not discharged dust is discharged to the outside of the machine from the end side of the processing chamber.

Dust-type thresher, (B) is a cutting board (10), raising case (11), cutting blade (12), grain culm transport mechanism (13), etc. The straw processing unit that looks into the end portion of the straw chain (14), (D) is a control unit including a driver's seat (15) and a driving operation unit (16), (E) is an engine, and (17) is It is arranged in front of the engine (E) and stores the first product from the suction and dust type thresher (A) through the fried cylinder (18). The grain tank (19) is a discharge auger for taking out the first product in the grain tank (17) out of the machine, continuously cutting the planted grain culms and threshing the harvested grain culms. Is configured to.

[0007] Next, the suction and dust type thresher (A) that composes the combine as described above will be described with reference to "Fig. 1" to "Fig. 3". In the chamber, the handling cylinder (9) is rotated in the direction of the arrow (a) to be constructed as a lower handling type, and (3) extends from below the handling chamber (1) into the closed dust collection chamber (2) at the rear. It comes out and swings back and forth, is discharged from the net (20) in the handling room (1) and is discharged from the drainage opening (21) on the drainage side of the handling room (1), and falls. An oscillating sorting body that sorts items and a leaked substance from the inside of a processing chamber (5) described later and sorts them by installing a Glen pan (22) and a Glen sieve (23) from the front end side on the front side. A chaff sheave (24) is disposed above the Glensieve (23), and a short portion is provided above the chaff sheave (24) and below the discharge port (21). The stroke - the rack (25) are provided, these are configured to swing together.

Reference numeral (26) is a cross-flow fan provided below the Glen pan (22) for raising the sort air, and the swing blower (3) is moved downward by wind blown from the cross-flow fan (26). A sorting air duct (4) that blows from the side toward the dust chamber (2) is formed, and (27) and (28) are the first and second troughs that are installed horizontally with the screw conveyor installed. , (29) is a suction dust collecting fan provided on the side of the feed chain (8) which is stretched along the handle (30) on the upper side of the dust collecting chamber (2).

The processing chamber (5) is on the side opposite to the feed chain (8) and swings from the culm side of the handling chamber (1). Since it extends to the side of the chamber (2) and is juxtaposed with the handling chamber (1), the processing cylinder (31) is rotatable in the processing chamber (5) in the arrow (B) direction. It has a built-in start end on the front end side that communicates with the culm side of the handling room (1) through the dust delivery port (32), and the end part on the rear end side has a large dust outlet opening on the rear wall ( It is released to the outside through 33). The end side of the second gutter (28) communicates with the upper part of the swing selection body (3) by a thrower (34), and extends diagonally rearward from the end of the feed chain (8). Straw chain (14) is extended.

As a result, the cutting culm is fed laterally through the handling chamber (1) by the feed chain (8) so that the crushed grain and the threshed straw are discharged from the culm outlet (21). Swing sorting is performed on the straw chain (14), which is carried out to the rear of the machine and which leaks from the receiving net (20) of the handling room (1) and falls from the outlet (21). Sorted by the swinging motion of the body (3) and the wind blown by the cross flow fan (26) and blown through the sorting air passage (4), the first product is taken out to the first product gutter (27) after being assembled. Is stored in the grain tank (17) and the second product is sent to the end side in the second product gutter (28) and returned to the start end side of the swing selection body (3) by the thrower (34). The dust in the dust chamber ((2) is sucked into the suction / dust fan (29) and discharged to the outside of the machine. Further, the unprocessed matter sent out from the dust delivery port (32) opening to the culm side of the handling room (1) is processed while being sent rearward in the processing room (5), and then from the room (5). Those that leaked fall into the rocking sorting body (3) and are sorted out, and the dust that has reached the end without leaking is discharged from the dust outlet (33) to the outside of the machine. It

Further, as shown in “FIG. 4”, the tip of the discharge auger (19) for appropriately discharging the No. 1 product stored in the grain tank (17) to a predetermined place is imaginary. Depending on how the wire is used, a shunt (36) is attached to the back of the tip to store it so that it can be discharged easily. As can be seen from the enlarged views of FIGS. 6 to 8, this shoe (36) has a U-shaped cross section, and its upper end side is attached to the pin shaft (37) so that the discharge auger is attached. It is attached to the tip of (19) and is adapted to receive and outflow the No. 1 material which has dropped from the discharge port (38) at the tip of the discharge auger (19). Further, it is more convenient if the mounting angle of the shoe (36) with respect to the discharge auger (19) can be appropriately changed and held.
