[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving net which is formed in an arc shape on the lower circumference side of a handling cylinder to form a handling room.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open No. Hei 2-171112 discloses a technique for supporting the receiving net so as to be movable around a handling cylinder.
As disclosed in Japanese Unexamined Patent Publication (Kokai) No. H11-209, there has been no other way but to remove clogs stuck in the eyes of the receiving net by removing the receiving net outside the machine and cleaning it.

[0003]

[Problem to be Solved by the Invention] As described above, in the conventional threshing machine, in order to remove the clogging material stuck in the receiving net, the receiving net has to be taken out of the machine, so that wasteful labor and time are wasted. Because it was necessary, in the present invention, without stopping the threshing machine and performing the above work again,
In the non-operation state where the cereals are not supplied to the handling room during operation, the clogging of the receiving net is automatically removed, saving unnecessary labor and time conventionally required, and contributing to the improvement of work efficiency. It was devised for the purpose of doing.

[0004]

SUMMARY OF THE INVENTION In order to accomplish the above-mentioned object, the present invention is to take the following measures, and the rotation of the teeth is provided around the lower side of the handling cylinder. The receiving net, which stretches in an arc along the trajectory and forms a handling room, can be freely moved closer to the toothing than a predetermined gap, and detects the presence or absence of grain stalks in front of the grain stalk supply port of the handling room. A cereal stalk sensor is provided, and the cereal stalk sensor and the movable mechanism of the receiving net are electrically connected to bring the receiving net close to the handling teeth when the cereal stalk sensor detects the cereal stalk “absence”. It was a configuration.

[0005]

With this configuration, the cereal stem supplied from the cereal stem supply port into the handling room keeps a predetermined gap between the toothing to be planted on the handling drum rotating in the handling room and the rotation locus of the toothing. Threshing is performed by a receiving net that is stretched and threshed, and the thresh that has been threshed is discharged out of the machine from the culm side, and the thresh in the handling room is sorted by air in a sorting device. By threshing, the culm at the tip of the spike is stabbed in the eye of the receiving net, so that the clogging is inevitably clogged and the effect of leakage from the receiving net is reduced.

Accordingly, the threshing machine is mounted on a traveling undercarriage to constitute a threshing unit of a combine. The threshing process is usually carried out by moving the planted grain culm in a cutting unit by advancing the body. When the machine reaches the end of the planted grain culm row, the machine rotates and re-moves to perform cutting and threshing. The culm is not supplied to the handling room and becomes non-operational, and the cereal culm sensor detects the cereal culm “absence”. The clogging material stuck in the eye of the receiving net will be caught by the tip of the rotating tooth and will be removed from the eyes, and the clogging will be automatically removed every time the aircraft rotates. Done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The receiving network of a threshing machine according to the present invention will be described below with reference to an example. (1) is a lower-handling type handling room in which a handle cylinder (2) is rotatably stored in the direction of an arrow (a), (3) is a toothing to be implanted on a peripheral surface of the handle cylinder (2), Reference numeral 4) designates a receiving net which is extended in an arc shape along the rotation trajectory of the teeth 3 on the lower circumference side of the handling cylinder 2 to form the handling chamber 1 and the rotation trajectory of the tip of the teeth 3 It is supported so as to be maintained at a predetermined gap (L) suitable for threshing. (5) is a grain culm supply port of the handling room (1), (7) is a culm opening, (8) and (9) are grain culms. It is a feed chain and a trapping rail which are laid along the handle from the supply port (5) side to the culm opening (7) side.

The receiving network (4) is a feed chain (8).
The end on the side is swung about the horizontal axis (10) as a fulcrum, and can freely move close to the tip of the tooth (3) so that it can be displaced from the predetermined gap (L) to a small gap. The displacement to the predetermined gap (L) and the small gap is performed by a movable mechanism (6), and the movable mechanism (6) meshes with a pinion (11) mounted on a motor (M) shaft. However, the feed chain (8) comprises a rack (13) connected to the end of the opposite receiving net (4) via an operating rod (12), and is displaced by forward and reverse rotation of the motor (M). It has become.

Further, (S) is a cereal stalk sensor which also serves as a handling depth sensor. The stalk is suspended from the stalk supply port (5) in front of and above the stalk supply port (5), and the stock is fed by a vertical transport chain (14). When the grain stalk reaching the grain stalk supply port (5) comes into contact with the stalk and the presence of the grain stalk is detected, the predetermined gap (L) is provided via the movable mechanism (6) and the handling depth is determined. Through the adjustment mechanism, the handling depth into the handling room (1) is made constant according to the length and length of the grain stalk, and when the grain stalk is not transported by the vertical transport chain (14), that is, the grain stalk "none" is detected. When to move the movable mechanism (6)
Thus, the end of the receiving net (4) is pushed to swing about the horizontal axis (10) as a fulcrum, and is displaced from a predetermined gap (L) to a small gap.

[0010] Thus, the grain culm is transported by the vertical transport chain (14), passed to the feed chain (8) and the clamping rail (9), and is passed from the grain culm supply port (5) to the handling room (1). When supplied in the cereal stalk sensor (S) is "Yes"
And the receiving net (4) is held at a predetermined gap (L), and the handling depth adjusting mechanism is operated according to the length of the culm to adjust the handling depth to a constant value. When the grain culm is not conveyed, the grain culm "absence" is detected, and by this detection, the receiving net (4) is pushed in the direction of the arrow (b) via the movable mechanism (6) to be displaced toward the toothing (3). Tooth treatment (3)
The tip is displaced to a small gap.

The displacement of the predetermined gap (L) from the predetermined gap (L) to the small gap causes the receiving net (4) to approach the tip of the toothing (3) and feed the cereal stalks into the handling chamber (1) to perform threshing. The tip of the rotating toothing (3) hooks and removes a clogging material such as a culm on the tip of the spike that is stuck in the eye of the receiving net (4) when the operation is performed.

In the above-described example of the present invention, the case of the under-handling type has been described. However, the above-described case of the upper-handling type is also applicable, and the receiving net (4) is described as a single piece. Divided into the culm supply port (5) side and drained culm port (7) side, or divided into the feed chain (8) side and the opposite side to form a plurality of receiving nets (4) However, the object of the present invention can be achieved by adopting a configuration in which each of those divided parts is individually connected to the movable mechanism (6) to be displaced or displaced in an interlocking manner.

[0013]

As described above, according to the present invention, the receiving net is formed by extending the handle (3) around the lower side of the handle cylinder (2) in an arc shape along the rotation locus of the handle (3). (4) is made movable freely from a predetermined gap (L) with respect to the tooth handling (3), and the presence or absence of a grain stalk is detected in front of the grain stalk supply port (5) of the handling chamber (1). A grain culm sensor (S) is provided, and the grain culm sensor (S) is electrically connected to the movable mechanism (6) of the receiving net (4), so that the grain culm sensor (S) becomes a grain culm. When detecting "none", the receiving net (4) is made to approach the tooth handling (3), so that in the threshing processing operation, the cereal culm sensor (S) detects the cereal culm "none". Is detected, the receiving net (4) is displaced from the predetermined gap (L) to a small gap by the movable mechanism (6), approaches the toothing (3), and removes clogging material stuck in the eyes of the receiving net (4). Times The clogging of the receiving net (4) is automatically removed in a non-operation state in which the grain stalk is not supplied to the handling room (1) during operation because the tooth is removed from the eyes by hooking at the tip of the handling tooth (3). As a result, the work efficiency was improved by eliminating the wasted labor and time conventionally required.
