2. Description of the Related Art Conventionally, as a threshing / sorting device of this type of combine, for example, as shown in Japanese Patent Application No. 8-411 filed by the applicant of the present application, the regulating member is a swing sorting device. It is proposed that the restriction member has a width substantially equal to the left-right width and the restriction member is capable of restricting the transfer of the amount of the processed material to the dust outlet evenly in the left-right direction.

[0003]

By the way, in the combine, the swing sorting device may be tilted in the left-right direction together with the machine body during steering. In such a case, the processed product on the swing sorting device may be inclined. Biased to one side in the left-right direction. However, in this manner, even if the processed material is biased to one side, if the restriction of the transfer of the processed material to the dust outlet by the regulating member is substantially evenly performed in the left-right width direction, the uneven paddy in the processed material is uneven. Therefore, there is a high possibility that waste etc. will be wastefully discharged from the dust outlet. On the contrary, if the regulation of the transfer of the processed material by the regulation plate is strengthened as a whole in the left and right width so that the reprocessable processed material such as the unbranched paddy is not discharged from the dust outlet in such a manner,
There is a problem that it becomes difficult to discharge straw dust, dust, and the like from the dust outlet, and remains in the threshing sorting device without being removed from the swing sorting device.

The present invention has been made in view of the above circumstances, and is a combine threshing / sorting device capable of performing a good sorting process by appropriately responding to the deviation of the processed products on the swing sorting device. The purpose is to provide.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of the combine. This combine comprises a machine frame 2 supported by a pair of left and right crawler traveling devices 1, 1, a threshing device 3,
The boarding control unit 4, the Glen tank 5, and the like are mounted and equipped, and the cutting pretreatment device 6 is attached to the front end of the machine body frame 2 so as to be vertically movable around the horizontal axis.

As shown in FIG. 2, the threshing device 3 feeds a grain culm cut by the pre-cutting processing device 6 into a feed chain 7.
Consists of a threshing part A for threshing while conveying at, a sorting part B for sorting threshed products, and a collecting part C for collecting the selected products of the sorted products in the Glen tank 5 and returning the roughly selected products. are doing. In the threshing unit A, the handling cylinder 8 that is driven to rotate about the front-rear axis is installed in the handling chamber 9, and the catching net 10 that leaks the treated products to the sorting unit B is stretched. I am configuring. The sorting unit B includes a swing sorting device 11 and a Kara 29 which blows air for sorting. Collection part C
Is composed of a first-collection device 12 that collects the selected product in the Glen tank 5, and a second-product recovery device 13 that returns the roughly-selected product to the selection device 11.

As shown in FIG. 2, the swing selecting device 11 has
The Glen pan 14, the chaff sheave 15, the Glen sheave 16, the Straw rack 17 and the like, which are located immediately below the receiving net 10, are provided by being erected on a supporting frame 18 which is driven to swing. Further, at the rear end portion of the rocking / sorting device 11, a regulating member 19 composed of a plate-shaped member that is long in the left / right direction is arranged over the entire lateral width of the rocking / sorting device 11. The restricting member 19 is attached to the support frame 18 at the rear end of the swing selecting device 11 in the front-rear direction axial center P at the center in the left-right width direction.
It is pivotally attached so that it can swing around. Then, as shown in FIGS. 3 and 5, in order to drive the restricting member 19 so that the restricting member 19 can be swung around the longitudinal axis P to change its posture, the restricting member 19 is provided at each of the left and right ends thereof. , One ends of the operation wires 20 and 20 are connected, and the other ends of the operation wires 20 and 20 are connected to both ends of a swing arm 22 which is swing driven by a single electric motor 21 as an actuator. are doing.

Further, as shown in FIGS. 2, 3 and 5, the amount of processed material transferred backward on the chaff sheave 15 is detected at two positions on the left and right sides of the chaff sheave 15 of the rocking / sorting device 11. Processed material amount detecting means 23, 2 as detecting means
3 are arranged. Each processed material amount detection means 23, 23
Since the thickness of the processed product increases as the amount of processed product on the chaff sheave 15 increases, the thickness of the processed product can be detected. That is, each processed material amount detecting means 23, 2
3, the potentiometer 23b detects the amount of rearward swinging caused by the contact of the detection arm lever 23a hung from the receiving net 10 with the object to be processed.
The detection signal of the potentiometer 23b is input to the control device 24 provided in the machine body. When the control device 24 determines that the amount of processed material is biased more than a predetermined amount in the left-right direction based on the detection signals from the respective potentiometers 23b, 23b, that is, the amount of processed material detected by the left and right potentiometers 23b, 23b is predetermined. If there is the above difference, the regulation to increase the regulation of the rearward transfer on the side where the processed material is unevenly present in the left-right direction and conversely weaken the regulation of the rearward transfer on the side where the processed material is small or absent. A drive signal for operating the electric motor 21 is output in order to drive the member 19 to change its posture to a predetermined inclined posture by swinging about the front-rear direction axis P.
In addition, when the amount of processed substances detected by the potentiometers 23b and 23b is almost equal, the regulating member 19 is set to the neutral position,
That is, the regulation of the backward transfer of the processed material is maintained in a posture in which it is substantially uniform in the lateral width direction. Incidentally, depending on the difference between the detected object amounts on the left and right potentiometers 23b, 23b, the larger the difference, the larger the displacement from the neutral position of the regulating member 19 may be controlled.

Therefore, according to the above configuration, for example, when threshing processing is performed even when the machine is turning in the headland during mowing work, the outer side of the machine is sorted by centrifugal force due to the turning of the machine. When the object is biased, the processed object amount detecting means 23, 23 detect the biased state, and based on the detection result, the control device 24 moves backward to the side where the object is biased in the left-right direction. Increased transport restrictions,
On the contrary, the regulation member 19 is swung around the longitudinal axis P so as to have a predetermined tilted posture so as to weaken the regulation of the rearward transfer on the side where the amount of the processed material is small or absent. As a result, on the side with a large amount of processed material, the processed material is regulated so as not to be unduly discharged from the dust outlet 25 opened in the outer case of the threshing device 3 behind the rocking sorting device 11, while the amount of processed material is small. In Kanagarawa, straw dust and dust are easily discharged from the dust outlet 25 by riding on the Karato wind from the Karato 29. Here, the control device 24, the electric motor 21, the operation wires 20, 20 and the like constitute the adjusting means 27 for adjusting the posture change of the regulating member 19 as described above.

[Other Embodiments] As shown in FIG. 4, the attitude of the regulating member 19 is changed so as to be linked to the operation of the steering lever 26 provided in the boarding control section 4. A detection means 28 (for example, a potentiometer, an encoder, a limit switch, etc.) for detecting the operation direction of the lever 26 is provided, and the control device 24, based on the detection signal of the detection means 27, controls the processed object to be processed in the left-handed direction. Due to the centrifugal force, the restricting member 19 is changed to an inclined posture of rising to the right and descending to the left because it is biased to the right on the rocking sorter 11 and the product to be processed is rotated on the rocking sorter 11 by the centrifugal force. Since it is biased to the left side, the restricting member 19 is changed to an inclined posture in which it goes up to the left and goes down to the right. In the above-described embodiment, the regulation member is configured such that a member having a length corresponding to the left-right width with respect to the swing selecting device is configured to be swingable around the central longitudinal axis, but the regulation member is It may be divided into two parts on the left and right, and the left and right restricting members may be configured to move up and down in a contradictory manner. In such a structure, a pair of actuators may be configured to vertically move each of the left and right regulating members.
