Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a receiving net that forms a lower circumference of a handling room of a thresher.

[0002]

[Prior Art]

 Conventionally, when the amount of grain culms supplied to the handling room becomes large, the mesh of the receiving net becomes clogged and the leak condition worsens, and the grain removal that goes around in the handling room with the rotation of the handling barrel increases and the waste is eliminated. There is a problem that the threshing performance is deteriorated and the grains are lost due to the extruded outside of the machine.

[0003]

[Problems to be solved by the device]

 In the present invention, when the grain culm is supplied in large amount in the handling room and the amount of grain removed in the handling room is increased and the load on the cutting edge is increased, the leakage mesh of the receiving net is enlarged to prevent the leakage condition. At the same time, it aims to eliminate the clogging of the net and eliminate the above-mentioned conventional drawbacks.

[0004]

[Means for Solving the Problems]

 Therefore, in order to provide the handling room net described in the preceding paragraph, the present invention attaches a cutting blade integrally to a fixed net that forms the lower side of the handling room in a direction orthogonal to the handling barrel axis. In this structure, a swing receiving net that can be freely swung is provided in a stack, and the size of the leakage net is changed by swinging the swing receiving net by the load fluctuation applied to the cutting edge.

[0005]

[Action]

 With this configuration, if the grain removal that moves in the handling chamber with the rotation of the handling cylinder increases, the load on the cutting blade of the grain removal that moves increases and the rocking net together with the cutting blade is fixed. And the leakage net formed by both receiving nets becomes large and the leakage action from the handling room is enhanced, and the load of the cutting edge is reduced when the above-mentioned round grain loss is reduced. Then, the rocking mesh is returned to normalize the leakage mesh. In addition, the swinging net reciprocates in a state of being placed over the fixed net in order to remove the clogging on the mesh.

A sorting air duct (16) that blows from the side is formed, and (17) and (18) are the 1st and 2nd troughs installed horizontally with a screw conveyor inside, and (19) is the dust chamber. It is a suction dust collecting fan provided on the side of the feed chain (21) which is stretched above the handle (20) above (8).

The processing chamber (10) is on the opposite side of the feed chain (21) from the culm side of the handling chamber (1). The processing cylinder (22) is rotatably built in the processing chamber (10) and extends in the treatment chamber (1) so as to extend to the side of the chamber (8). Communicates with the handling chamber (1) through the dust delivery port (23), and the rear end portion thereof opens toward the dust removal chamber (8). The end side of the second gutter (18) communicates with the upper part of the swing selection body (7) by the thrower (24), and the straw chain is slanted backward from the end part of the feed chain (21). (25) is extended.

As a result, the cutting culms are fed laterally through the handling chamber (1) by the feed chain (21) so that the crushed grain is processed and the threshed straw is discharged from the culm outlet (9). The ones that are inherited by the straw chain (25) and carried out to the rear of the machine, and those that leak from the handling room (1) and those that fall from the outlet (9) are the rocking motions of the rocking sorter (7). And the cross flow fan (15) creates wind and blows through the sorting air duct (16) to select, and the first item is taken out after gathering in the first item gutter (17) and the second item is 2 The inside of the guard gutter (18) is sent to the end side and returned to the start end side of the swing sorting body (7) by the thrower (24) to be re-sorted and opened to the drainage side of the handling room (1). What is sent out from the dust inlet (23) is processed while being sent backward in the processing chamber (10) and leaks from the chamber (10). Those that fall into the swing sorting body (7) are sorted, and those that reach the rear end are discharged into the dust chamber (8) and discharged to the outside of the machine by the suction force of the suction dust collecting fan (19). Be dusted.

Next, the fixed receiving net (2) forming the lower circumference of the handling chamber (1) is stretched over the net frame (26) and is provided between the grain culm supply side and the culm outlet (9). The size of the mesh of the fixed net (2) is fixed and the swing net (4) is also stretched over the net frame (27) and is provided between the grain culm supply side and before the culm mouth (9). Is formed in the same way.

The swing receiving net (4) has a slightly long hole on the feed chain (21) side and the back side on both sides of the net frame (27) on the grain culm supply side and the culm mouth (9) side. Rocking allowance holes (28) ... are provided, and support protrusions (29) ... protruding from the machine body are inserted into the allowance holes (28). The net (2) is placed under the net (2) with a small gap therebetween, and is swingable in the direction orthogonal to the axis of the handling cylinder (6). Further, a cutting blade base (30) is integrally extended upward on the back side of the mesh frame (27) of the swing receiving net (4), and the cutting blade base (30) is laterally aligned with the cutting blade base (30). A plurality of cutting blades (3) ... Are attached at intervals.

Further, the feed chain (21) side of the net frame (27) of the swing net (4) is set in a direction opposite to the rotation direction (a) of the handling cylinder (6) by the tension spring (31). In the retention state shown in "Fig. 1", the swing receiving net (4) is displaced from the fixed receiving net (2) as shown in "Fig. 2", and the leakage nets (5) are each receiving nets (2). When the mesh of (4) becomes half, it becomes a normal leaking mesh, and when the grain loss circulating in the handling chamber (1) increases and the load applied to the cutting edge (3) increases, the tension spring ( 31) Pushes the cutting edge (3) in the rotational direction (a) against the pulling force of the rocking allowance hole (28) ... Then, as shown in FIG. 3, the swing receiving net (4) matches the fixed receiving net (2), and the leakage net (5) is enlarged.

[0014] Therefore, when the grain removal that goes around with the rotation of the handling barrel (6) in the handling room (1) increases, such as when a large amount of grain culm is supplied into the handling room (1), The load applied to the cutting blade (3) of the rotating threshing material increases, and the cutting blade (3) is pushed up as shown by the arrow (B), and the swing net (4) is the tension spring (31). The rocking allowance holes (28) ... slide against the supporting projections (29) .. The other side abuts and locks against the support protrusion (29), and the leakage network (5) is greatly changed as shown in FIG. 3 to enhance the leakage action from the handling chamber (1). Then, when the above-mentioned rounded grain removal decreases, the load of the cutting blade (3) decreases, and the rocking net (4) is moved back by the urging force of the tension spring (31) as shown by the arrow (C). As described above, the swing receiving net (4) is displaced from the fixed receiving net (2), and the leakage net (5) becomes a normal one. Further, the reciprocating motion of the swing receiving net (4) removes the clogging on the receiving nets (2) and (4).
