Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a grain culm transporting device applied to a harvesting machine such as a binder or a combine.

(B) Conventional technology Conventionally, as a crop transporting device, the middle part of the stalk of a napped crop is raked by a stalk sweeping belt having a sweeping claw having a receding angle above the cutting blade. Japanese Patent Application Laid-Open No. 61-100121 has already known that the root end of the stock is scraped by a scraping rotary member provided with a projection having a receding angle larger than that of the scraping claw.

(C) Problems to be solved by the invention Since the scraping rotary member in the known crop transporting device is largely spaced downward from the stem scraping band, straw scraps and grain culms are stalk scraping bands. It was not possible to remove the leaves and stems that were entangled or wrapped around the scraped nails.

Also, if the scraping rotary member is brought close to the stalk conveying belt and is not used for winding prevention, not only a separate boss for mounting the rotary shaft is required, but also the cost is increased, and the scraping rotary member Since the protrusion cannot be brought sufficiently close to the scraping claw, it is not possible to prevent the winding properly.

(D) Means for Solving the Problems In the present invention, a transport chain having a transport claw on one side is stretched along a grain culm transport path, and a sprocket boss around which the end of the transport chain is wound is attached to a boss. Attaching a sweeping plate having a sweeping claw that approaches the transporting claw, making the escape angle of the sweeping claw with respect to the transport path larger than the escape angle of the transporting claw, and synchronizing the transporting claw and the sweeping claw As a result, the above-mentioned problems are solved.

(E) Action The transport claw of the transport chain locks the culm and transports it along the transport path, and when it reaches the end of the transport, the sweeping claw of the sweeping plate is in a state of approaching the transport claw and undergoing a large retreat. The culms around the conveying claw are pushed out by the corners and eliminated. Further, since the raking claw is attached to the boss of the sprocket, the cost can be reduced and the raking claw can be sufficiently brought close to the conveying claw.

(F) Example An example of the present invention will be described with reference to the binder shown in the drawings. The grass bodies 1, 1 and the medium grass body 2 and the grain culm raising bodies 3, 3 are provided in the front part of the machine body, and behind them. A cutting blade 5 is arranged, and a substantially horizontal slit 7, 7 is formed in a guide plate 6 inclined obliquely rearward at the rear portion of the cutting blade 5, and both ends thereof are stretched by hanging sprockets 8, 8a. A plurality of transporting claws 9 ... Installed at appropriate intervals so as not to undulate are provided side by side, and the transporting claws 9 ... Push the transport chain 10 forward with a guide 11. As a result, it moves to the lower grain culm raising body 3 side while entering the conveying path formed on the front surface of the guide plate 6 from the slit 7.

In addition, a binding device 12 provided at the transport end of the transport chain 10.
Binds the harvested culms and discharges them sideways.

A sprocket plate 17 having a squeezing claw 16 is fixed to the boss portion of the sprocket 8 mounted on the shaft 13 on the conveying end side via a bearing 15. FIG. 1 and FIG. 3 show the projecting claw 16 and the carrying claw 9 in a state where the base of the carrying claw 9 overlaps the outer circumference of the sprocket 8.
As shown in (d), they are assembled in synchronism so that they match when viewed from the axial direction.

Further, the clearance angle A of the carrying claw with respect to the guide plate 6 forming the carrying path is smaller than the clearance angle B of the scraping claw 16.

In the above-mentioned binder, the grass bodies 1, 1 and the medium grass body 2
The grain culms that have been weeded by the grain culverts raised by the left and right grain culm raising bodies 3, 3 are mowed by the cutting blade 5, and when they lean against the guide plate 6, they are laterally conveyed by the conveying claws 9 ...

Then, at the end of conveyance of the conveyor chain 10, as the conveyance claw 9 approaches the sprocket 8 from the end of the guide 11, as shown in FIGS. 3 (a) and 3 (b), it sequentially retreats with respect to the guide plate 6. At the same time, the tip of the grain sticks approached the rotation locus of the sweeping claw 16 and was locked by the transporting claw 9 until the state shown in (c) was reached. It is pushed out by the scraping surface 16a of 16 and immediately before the conveying claw 9 is retracted to the rear of the guide plate, the tip thereof coincides with the tip of the scraping claw 16 as shown in FIG. It will not be locked, and will not involve the grain culm.

Further, the escape angle A of the conveying claw 9 is smaller than that of the scraping claw 16. That is, since the rising angle C of the conveying claw 9 is large, when it projects forward from the slit 7 of the guide plate 6 and conveys the grain culm, it can be efficiently conveyed because the escape angle A is small. it can.

The grain culms thus conveyed are bound by the binding device 12 and discharged to the lateral fields by the sweeper 18.

(G) Effect of the Invention Since the present invention is configured as described above, when the conveying claw 9 of the conveying chain 10 locks the grain culms and conveys them along the grain culm conveying path and reaches the end, The scraping claw 16 of the exit plate 17 is formed by hooking the conveying claw 9 and bending the straw or grain culm and the conveying claw 9.
It will enter into the space between and and will be slowly pushed out at a receding angle larger than the conveying claw 9 to be removed, so that it is possible to reliably prevent the waste claws and grain culms from being entangled or wrapped around the conveying claw 9.

Further, since the scraping plate 17 is fixed to the boss of the sprocket 8 around which the end side of the transport chain 10 is wound, the boss can be shared and the cost can be reduced, and the sweeping pawl 16 can be sufficiently mounted on the transport pawl 9. Can be approached.
