Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sensor for detecting the amount of fins of a rocking sorter for sorting unhandled items from a handling room.
The present invention relates to a fin-interval adjustment control device that adjusts widely based on the detection of.

[0002]

2. Description of the Related Art Conventionally, in an apparatus that detects the amount of straw discharged after threshing and adjusts the fin interval of a rocking sorting body based on that detection, for example, the machine is moved to the end of the grain culm row. At the beginning of letting U turn, the threshed straw after threshing is carried out and the detected amount becomes zero and the fin interval is adjusted to "closed", but at that time it is still on the rocking sorter. The rear part is oscillatingly transferred and is not sorted out and is discharged to the outside of the machine, resulting in No. 3 loss.

[0003]

DISCLOSURE OF THE INVENTION The present invention eliminates the disadvantage of the conventional adjustment control device which is discharged to the outside of the machine due to the adjustment of the fin interval and loses the No. 3 loss and eliminates the No. 3 loss. It was created in order to be collected and re-sorted as.

[0004]

SUMMARY OF THE INVENTION Therefore, as described in the preceding paragraph, the present invention selects the unhandled goods from the handling room in order to provide the thing that can be recovered as the second thing by eliminating the third loss. The swing sorting body is divided into a front part and a rear part.
By linking each adjustment mechanism that adjusts the fin gap between the front and rear wales with the grain culm amount detection sensor, when detecting the grain culm amount "large", the front fin gap is widened. This is characterized in that the rear part has a narrow fin interval and the front part has a narrow fin interval when a "small" is detected, and the rear part has a wide fin interval.

[0005]

With this structure, the grain culms that have been mowed by the mowing unit, transported to the threshing unit, and supplied into the handling chamber are threshed.
The handled goods fall on the rocking sorting body and are sorted by the rocking action. At this time, when the grain culm amount detection sensor detects the amount of grain culm passing through the grain culm passage and detects the grain culm amount "high", the front part of the swing sorting body is based on the detection and the fin of the culm is detected. The interval is widened to promote the leakage of grains to cope with a large processing flow rate, and at the same time, the fin interval of the rear gutter is adjusted narrowly to adjust the leakage action and improve the sorting accuracy.

In addition, when the grain culm amount detection sensor detects a grain culm amount "small" when the machine body travels to the end of the grain culm row and turns around, the fin interval of the front part is narrow. The fin spacing of the rear part is wide. At this point, the processing flow rate on the rocking sorting body is still high and the fin portion of the front part is narrowed so that the rear part is about to be sent to the wager. Since the rear part of the fish has a wide fin interval, it is actively dropped from between the fins and collected in the second trough and does not scatter out of the machine, resulting in no third loss. Further, the processing flow rate on the rocking sorting body decreases with the passage of time, but the fin interval at the front part is narrowed, so that the sorting accuracy by leakage is improved.

That is, (1) is a handling chamber containing a handling cylinder (7), and (a) is a portion extending from below the handling chamber (1) into a rear dust chamber (8) and swinging in the front-back direction. Leakage from the net (9) of the handling room (1), what is discharged from the outlet (10) of the handling room (1) and falls, and from the inside of the processing chamber (11). An oscillating sorting unit that receives and sorts objects from the front end side of the transfer plate (12) and the oscillating sorting body (2) (details are chaff sheaves; The chaff sheave (2) is divided into a front portion (2a) and a rear portion (2b), and the chaff sheave (2) is arranged below the front portion (2a) by the Glensive (13). ) Are provided so that they are integrally rocked back and forth.

Further, (14) is a compressed air fan provided below the transfer plate (12) for raising the selected air, and the swinging selection section (a) is driven by the air blown from the compressed air fan (14). A sorting air passage (15) is formed from the lower side, and (16) is a front part of the chaff sheave (2) (2).
No. 1 gutter that collects the No. 1 leaked from a) and passed through Glensive (13), (17) No. 2 gutter that collects No. 2 leaked from the rear part (2b) , (18) are suction dust-exhausting fans provided with a feed chain (6) which is provided above the dust-exhausting chamber (8) along the handle (19).

The processing chamber (11) is opposite to the feed chain (6), and one side of the rocking sorting section (a) is provided above the wrinkle of the handling chamber (1) and is disposed in the front-back direction to remove dust. The processing cylinder (20) is rotatably incorporated in the processing chamber (11) and extends from the side end of the chamber (8) to the treatment chamber (1). The culm of the handling room (1) communicates with the handling room (1) through the dust-sending port (21) opening in the handling room (1), and the end of the culm is open toward the dust collecting room (8). . In addition, the transport end of the second gutter (17) is a thrower (22).
Is communicated above the transfer plate (12) by means of a straw chain (2) diagonally rearward from the end of the feed chain (6).
3) is extended.

As a result, the cut culm is fed laterally through the handling chamber (1) by the feed chain (6) so that the threshed threshing and threshed straw exits from the culm mouth (10). (23) inherited and discharged to the rear of the aircraft,
Leakage from the net (9) of the handling room (1) and the outlet (10)
Items falling from the screen are sorted by the swinging action of the swing sorting section (a) and the wind blown by the pressure air fan (12) and blow through the sorting air passage (15), and the first item is the first item gutter ( 1
It was taken out at 6) and the second one was the second one (17).
From the thrower (22), the start end of the rocking sorting part (a) is returned to the saw and re-sorted, and the culm of the handling chamber (1) is not sent out from the dust delivery port (21) opening in the saw. The processed material is processed while being sent to the end in the processing chamber (11), and the material that leaks from the chamber (11) falls to the rocking sorting section (a) and is sorted, and reaches the end portion. The substances are discharged to the outside of the machine by the suction dust discharge fan (18) together with the dust discharged into the dust discharge chamber (8) and blown up by the sorting air passage (15).

Next, as shown in FIG. 1, a trapping rail (24) is installed below the straw chain (23) to form a grain culvert passage formed by the installation. The straw is discharged through, but the start end and the end of the pinch rail (24) are pressed upward by a compression spring, and the amount of grain culm passing through this grain culm passage is suppressed. The pinching rail (24) is a grain culm amount detection sensor (S) that moves up and down due to fluctuations in layer thickness to detect the amount of grain culm. And (2
5) is an actuating rod that can move up and down around a shaft (26) as a fulcrum and is urged upward by a torque spring (not shown) to follow the vertical movement of the pinching rail (23).

The chaff sheave (2) is formed by arranging fins in parallel, and the front portion of the chaff sheave (2a) has a lower end shaft (28) interlocked with the upper end shaft (27) as a fulcrum. The inclination angle of each fin (3a) is changed all at once by the forward and backward movement of the interlocking member (29) connected to the member (29) to widen the gap between the fins (3a). Similarly, the rear part (2
In the case of b), the lower end shaft (31) uses the upper end shaft (30) as a fulcrum.
Are moved forward and backward by the interlocking member (32) to widen the space between the fins (3b).

The front parts of (4) and (5) are (2)
The adjustment mechanism (4) of the front part (2a) is a base (33), and the adjustment mechanism (a) is for adjusting the distance between the fins (3a) and (3b) of the rear part (2b). A manual adjusting plate (34) and a sensor adjusting plate (35) which swing around the upper end shaft (27) of the frontmost one of the fins (3a) and engage with the lower end shaft (28). The manual type is attached to the manual lever (3) via the wire (36).
7), the one for the sensor is the above-mentioned operating rod (25)
Wire from the base of the arm to the arm (38) protruding upward.
The rear wrinkle adjusting mechanism (5) is connected by (39) and swings around the upper end shaft (30) of the frontmost end of the fins (3b) to engage with the lower end shaft (31). The adjusting rod (40) that swings together is connected to the arm (38) by a wire (41), and the fin (3a) of the front wrinkle (2a) is connected by a manual lever (37). The fin (3a) interval can be adjusted by changing the inclination angle of the grain (3a), and the grain culm amount detection sensor (S) detects the layer thickness passing through the grain culm passage to detect the grain culm amount "high". When doing so, the inclination angle of the fins (3a) of the front part (2a) becomes steep and the gap between the fins (3a) is widened, and the fin (3b) of the rear part (2b) is made to have a gentle inclination. (3b) When the interval is narrowed and the grain culm amount "small" is detected, the front part is conversely (2a).
The fin (3a) is narrowed and the rear fin (2b) is widened.

Further, an adjusting mechanism (5) for the rear row (2b)
Is for connecting the adjusting rod (40) and the wire (41) through the spring (42), and when the amount detected by the grain culm amount detecting sensor (S) is abnormally large, this spring ( 42) is extended so that the fins (3b) are kept at an interval that allows grain to leak and be sorted.

Therefore, when the grain culm amount detection sensor (S) detects the amount of grain culm passing through the grain culm passage and the grain culm amount "high" is detected, the operating rod (25) arm (38) ) ・ The adjusting plate (35) for the sensor is rotated through the wire (39), and the interlocking member (29) is used to widely adjust the intervals of the fins (3a) of the front part (2a) to the grain. The leakage of water is promoted to cope with a large processing flow rate, and at the same time, the fin (3b) of the rear row (2b) is separated by the operating rod (25) and arm (38).
An interval for performing a normal leaking action by rotating the adjusting rod (40) via the wire (41) and simultaneously narrowing the intervals of the fins (3b) by the interlocking member (32). Is adjusted to improve the sorting accuracy.

When the grain culm amount detection sensor (S) detects the grain culm amount "small", each member operates in the opposite manner to the above and the interval between the fins (3a) of the front part (2a) is increased. Becomes narrower and the fin (3b) spacing of the rear gutter (2b) is adjusted to a wider gutter. At this point, the processing flow rate on the chaff sheave (2) is still high and the fin (3a) of the front part (2a) has become narrower, so that the rear part (2a) has become smaller.
Although it is about to be sent to b), the sent one is actively dropped from between the fins (3b) because the space between the fins (3b) of the rear part (2b) is widely adjusted and the second one is sent. It will be collected in the gutter (17).

If the manual lever (37) is operated,
The adjustment plate (34) for manual operation is rotated via the wire (36) so that the interval between the fins (3a) of the front part (2a) is wide and narrow regardless of the detection by the grain culm amount detection sensor (S). Adjust to
Even if the grain culm amount detection sensor- (S) detects an abnormal grain culm amount, the fin (3b) interval of the rear part (2b) keeps the limit interval for selecting grains by the interposition of the spring (42). The front part is sent from the wa (2a) and is sorted down and collected in the second gutter (17).

Further, (43) shows an acceleration sensor, and the grain culm amount detecting sensor (S) detects the grain culm amount "small" at the end of the grain culm row. Since it is always detected when traveling, it is used as a means for detecting the traveling and is provided at the rear end or the front end of the machine body, and the grain culm amount detection sensor by detecting the traveling-
The fin interval may be adjusted in the same manner as when (S) detects the grain culm amount "small".
