The first thing is stored in the Glen tank 30 through the first conveyor 28 through the fry conveyor 29, and the second thing is returned to the front of the sorting device 19 through the second conveyor 31 through the reduction conveyor 32. is there. The first thing conveyed to the upper part of the grain tank 30 by the above-mentioned fry conveyor 29 is sent forward by the leveling conveyor 54, and is a leveling disk including a rotating blade provided at a substantially central position in the front-rear direction of the grain tank 30. It is thrown toward the center of the tank by 55,
The grains in the Glen tank 30 are stored uniformly.

The Glen tank 30 is located above the threshing unit 18 and has a width substantially equal to the width of the body frame 13.
Both the first rotor 21 and the second rotor 22 are arranged below the Glen tank 30. A discharge conveyor 33 is accommodated in the lower part of the Glen tank 30 on the right side in the advancing direction of the machine body in the front-rear direction.
The rear end of 3 communicates with the lower end of the grain discharge conveyor 52, which projects above the side surface of the Glen tank 30, and whose upper end communicates with the base of the discharge auger 34.
The discharge auger 34 is horizontally extended forward, is rotatable up and down, left and right, and is capable of moving the tip of the discharge auger 34 to an arbitrary position so that the paddy in the Glen tank 30 can be discharged to a truck bed or the like. Like that.

As shown in FIG. 2, a power input case 115 is disposed below the vertical conveyor 52, and the power of the engine 53 is reduced by the reduction case 121 and input into the power input case 115. Power input case 1
While the discharge conveyor 33 is driven via a bevel gear mechanism or the like in the device 15, the screw in the discharge auger 34 is driven from the vertical conveyor 52 via another bevel gear mechanism. As described above, since the power transmission path for discharging the paddy is divided into two directions, that is, the direction of the discharge conveyor 33 and the direction of the vertical conveyor 52 and the discharge auger 34, for example, the discharge conveyor 33,
Compared to a configuration in which power is sequentially transmitted to the vertical conveyor 52 and the discharge auger 34, the power transmission unit path for continuously transmitting power can be shortened, thereby preventing an excessive load from being applied to an interlocking unit such as a gear. I have.

The Glen tank 30 is rotatably supported on the side of the body frame 13 about the rotation axis of the discharge conveyor 33. Hydraulic cylinders 56 are provided at the front and rear ends of the lower surface of the Glen tank 30. The lower ends of the hydraulic cylinders 56 are pivotally supported by a body part in front of the first rotor 21 and a body part behind the second rotor 22, respectively.

Further, an engine 53 is disposed behind the Glen tank 30. A lower portion of the engine 53 is connected to an axle 36 via a transmission case, a transmission case, and the like. A drive sprocket is fixed to the axle 36 so that the crawler traveling device 1 can be driven to travel.

Next, the structure of the sorting device 19 of the present invention will be described in detail with reference to FIGS. A substantially lower half of the first rotor 21 is covered with a receiving net 20a.
Below the "a", there is provided a slug 25 having a slight inclination, and on the slug 25, a direction plate (not shown) is provided. As a result, a mixture of a large amount of grains and the like that are threshed by the fibrillation action between the first rotor 21 and the receiving net 20a is:
The grain is dropped onto the grain board 25, and in order to effectively perform the sorting in the next step, the grain is leveled by the direction board and the swing and the specific gravity is sorted.

A chaff sheave 60 is disposed below the receiving net 20b of the second rotor 22 and below the rear end of the flow tray 25 so that the front end thereof overlaps. The chaff sheave 60 has an inclined plate 6 having an inverted “H” shape in a side sectional view.
. 0a, 60a... Are laid horizontally at predetermined intervals in the front-rear direction, and a large straw or the like of the mixture transferred on the drifting plate 25 is transferred rearward on the inclined plate 60a,
The remainder passes through the gap between the inclined plates 60a and falls on the Glen sheave 26 disposed below, and is roughly sorted. Further, the mixture threshed by the second rotor 22 also falls on the chaff sheave 60 and is subjected to rough sorting. The inclined plate 6
Increasing the angle of 0a increases the amount of leakage and increases the amount of sorting in high-speed reaping work, etc. Conversely, decreasing the angle decreases the amount of leakage and reduces the amount of straw by the hook at the lower end of the inclined plate 60a. It is effective when the amount of cereal stems is small.

A grain sieve 26 is disposed below the chaff sheave 60, and a Karin 27 is arranged in front of the Glen sheave 26. As a result of being carefully selected in combination with the wind of the above, the above-mentioned first thing is obtained. In addition, Glensheave 26
Has a structure that covers the range from the front end of the chaff sheave 60 to the top of the conveyor 28, so that the mixture remaining after the fine sorting can be dropped to the rear of the conveyor 28 and re-sorted.

A transfer device 61 is provided on the bottom plate 63a of the swing sorting section 63 below the grain sheave 26. The transfer device 61 is provided with a front transfer device 61a provided in front of the first conveyor 28, And the rear conveyor 61b provided between the second conveyors 31. Of these, the first object is the first conveyor 2b by the front conveyor 61a.
8 and falls to the transfer gutter 28a of the first conveyor 28. The above-mentioned large straw, dust and the like conveyed rearward on the chaff sheave 60 are discharged to the rear of the machine body by the suction fan 62, and short straw, grains and the like slide down on the second conveyor 31. Further, the mixture dropped from the gap during the transfer on the chaff sieve 60 or the remaining mixture after the fine separation dropped from the rear end of the Glen Sheave 26 is transferred to the rear transfer device 61b.
Is transported to the second conveyor 31 and falls to the transfer gutter 31a.

The first thing dropped into the conveyor is conveyed by the first conveyor 28 to the lower end of the fried conveyor 29, and is carried into the Glen tank 30 by the fried conveyor 29. The second product is conveyed by the second conveyor 31 to the lower end of the reduction conveyor 32, and then returned to the running plate 25 in front of the swinging selection unit 63, where the second product is sorted again.

In the case of the present embodiment, the same swinging feed plate as that of the flowing grain plate 25 is used as the transporting device 61. However, any device can be used as long as it can transport the grains and straws to the respective conveyors for lateral movement. Well, it is not particularly limited. However, when it is necessary to cope with a mowing operation or a high-speed threshing operation after rain, a forced-conveying type conveying device such as a belt conveyor is preferable.

In the present invention, as shown in FIGS. 4 and 5, a first conveyor 28 is provided horizontally behind the crawler-type traveling device 1, and a left-hand conveyor is provided at the left end of the first conveyor 28. The lower end of the second conveyor 31 is communicated with the lower end of the second conveyor 31 and the lower end of the reduction conveyor 32 is connected to the right end of the second conveyor 31. And the first conveyor 28, the second conveyor 31
Is disposed behind the crawler traveling device 1.

With such a configuration, the swinging sorter such as the Glen Sheave 26 and the chaff sheave 60 can be arranged between the left and right crawlers, and the sorting path can be lengthened to improve the sorting accuracy. It is possible to arrange the sorting device even lower than before. Further, although the frying conveyor 29 and the reduction conveyor 32 are arranged so as to protrude beyond the left and right widths of the sorting device, since they are arranged behind the crawler type traveling device 1, they do not interfere with the crawler, and There is no interference with the one rotor 21 or the second rotor 22. Therefore, the first rotor 21 and the second rotor 22 can be made substantially the same length as the vehicle width, so that the threshing path can be lengthened, and the degree of freedom for arranging the lifting conveyor 29 and the reduction conveyor 32 can be improved. Therefore, the selection range of the arrangement of the Glen sheave 26 and the chaff sheave 60 can be expanded.
