Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for preventing clogging of a net which forms the lower side of a handling room.

[0002]

[Prior Art]

 Conventionally, when threshing moist material etc., the nets are clogged and the leakage from the handling room is significantly reduced, and the grains are scattered 3 or stuck in the straw and are discharged outside the machine. Therefore, in order to solve this phenomenon, it is easy to remove the clogging by removing the receiving net from the machine like the one disclosed in JP-A-2-171112. The means had been devised.

[0003]

[Problems to be solved by the device]

 However, although various means have been devised to facilitate the work of removing clogging by cleaning by removing the net from the receiving machine as described above, the threshing work is destined to be taken out of the machine. In addition to the interruption of work, the labor and time required therefor are wasted.Therefore, in the present invention, the work can be continued while continuing the work without taking out the work net from the machine and without interrupting threshing. It is designed for the purpose of preventing clogging and providing a simple structure with a low cost.

[0004]

[Means for Solving the Problems]

 Therefore, in order to achieve the object described in the preceding paragraph, the present invention mounts a receiving net forming the lower side of the handling chamber swingably in a direction orthogonal to the axis of the handling cylinder, and stretches the receiving net. The cutting edge is integrally attached to the mesh frame, and vibration is applied to the receiving net due to load fluctuations on the grain cutting edge that rotates in the handling chamber in the direction of rotation of the handling cylinder. ..

[0005]

[Action]

 With this configuration, when a group of grain-removing grains that rotate in the handling chamber with the rotation of the handling cylinder collide with the cutting edge, the load on the cutting edge becomes large and the receiving net moves forward, causing the group to pass through. As the load is reduced and the bobbin moves back, vibration is imparted to the receiving net through the cutting edge by repeating the intermittent collision of the grain removal with the cutting edge, and the vibration and the collision of the cutting edge The recoil that occurs at that moment dispels what is trying to block the mesh.

【Example】

 Hereinafter, the clogging prevention device according to the present invention will be described with reference to the accompanying drawings. The thresher equipped with this device is for combine harvesters. In the figures, "Fig. 3" and "Fig. It is on the front side with respect to the traveling direction, and the harvested culms are taken over by the feed chain, laterally pinched and threshed in the handling room.

That is, (1) is a handling room having a handling barrel (5) built therein, which is configured as a lower handling type by rotating the handling barrel (5) in the direction of the arrow (a), and (7) is a handling chamber. Leakage from the net (2) of the handling chamber (1) and the discharge of the handling chamber (1) by extending from below (1) into the rear dust chamber (8) and swinging in the front-back direction. An oscillating sorting body that sorts out what is discharged and dropped from the culm opening (9) that opens to the culm side and what leaks from the inside of the processing chamber (10). A gren pan (11) and a gren sieve (12) are erected from above, a chaff sheave (13) is disposed above the gren sieve (12), and the culvert is located above the chaff sheave (13). A short-length straw rack (14) is provided below the mouth (9) and is configured to swing together.

Reference numeral (15) is a cross-flow fan provided below the Glen pan (11) for raising the selection wind. The cross-flow fan (15) blows down the swinging selection body (7). 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 outlet (23), and the rear end portion thereof opens toward the dust exhaust 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 cut culms are fed laterally in the handling chamber (1) by the feed chain (21) so that the crushed grain is processed and the threshed straw is discharged from the drainage opening (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), 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 outside the machine by the suction force of the suction dust collecting fan (19). Be dusted.

Next, the net (2) forming the lower side of the handling chamber (1) is stretched around the net frame (3) and provided between the grain culm supply side and the partition plate (26). Another fixed net (27) is stretched between the partition plate (26) and the outlet (9).

Both sides of the net frame (3) of the receiving net (2) on the grain culm supply side and the culm outlet (9) side extend from the side of the feed chain (21) to the inner side of the shaft (28). ) Is provided with several rollers (29) which are rotatably supported, and these rollers (29) are fixed to the fuselage side under the rollers (29). It is mounted on the rails (30) (30) on both sides of the arc shape and oscillated in the direction orthogonal to the axis (6) of the handling cylinder (5), that is, in the rotating direction (a) of the handling cylinder (5). It is movably mounted. The roller (29) is made of rubber or the like and has elasticity.

Further, a connecting fitting (31) is fixedly provided on the upper edge portion on the back side of the net frame (3), and both sides of the connecting fitting (31) and the cutting blade base (32) are downward from the bottom. The parts (33) (33) to be projected are connected via a connecting shaft (34), and project from both ends of the cutting table (32) toward the opposite side of the handling cylinder (5). The members (35) and (35) are attached to the support shafts (36) and (36) of the machine body, and are laterally spaced on the surface of the cutting table (32) facing the handling cylinder (5). By attaching the individual cutting blades (4), the cutting blades (4) can be moved up and down with the support shaft (36) as a fulcrum, and integrally with the swingable receiving net (2). It is configured to swing.

A tension spring (37) is interposed between the member (35) and the fuselage side and compressed between the end of the mesh frame (3) on the feeder chain (21) side and the fuselage side. With the leaf spring (38) interposed, the tension spring (37) urges the cutting blade (4) downward, and the downward urging causes the net frame (3) to hit the fuselage side. Is absorbed by the compression leaf spring (38) so as to soften.

Therefore, when a group of grain-removing grains that rotate in the handling chamber (1) with the rotation of the handling cylinder (5) collide with the cutting blade (4), the load applied to the cutting blade (4) becomes large, and the tension spring is pulled. The cutting edge (4) is pushed up as shown by the arrow (b) by overcoming the urging force of (37), and at the same time, the catch net (2) moves in the direction of rotation (a) and the load is passed by the passing of the group. Becomes smaller and is returned by the urging force of the tension spring (37). Thus, by repeating the intermittent collision of the grain loss with the cutting edge (4), the cutting edge (4) ) Is applied to prevent the clogging of the mesh that is trying to clogging the mesh due to the vibration and the recoil impact generated when the cutting edge (4) collides.

[0016] As shown in "Fig. 7", a straw-conveyor section for carrying out the threshed straw backward by the straw chain (25) of the threshing machine has a truncated cone shape in its tip side passage. Several rotators (39) are installed in a row and the tip side of the straw that is carried out is diffused into a conical shape to collect the stuck particles in the carrying out process.

[0017]

[Effect of the device]

 As described above, the clogging prevention device in the present invention allows the net (2) forming the lower side of the handling chamber (1) to swing in the direction orthogonal to the axis (6) of the handling cylinder (5). The cutting blade (4) is mounted integrally on the net frame (3) that stretches the net (2), and the inside of the handling chamber (1) is rotated in the direction of rotation of the handling cylinder (5) ( Since the vibration is applied to the net (2) by the load fluctuation applied to the grain removing blade (4) that goes around (a), it occurs when the vibration and collision with the blade (4) occur. The recoil impact dispels any attempts to clog the mesh, and the net (2) is not removed from the machine and the threshing is continued without interruption of threshing ( It was possible to effectively prevent clogging in 2) and to provide what was obtained with a simple structure and at low cost.
