JP 2001-299051 A

  In the above-mentioned conventional configuration, the start end of the threshing feed chain and the start end of the takeover conveying chain are mounted on the same axis line and coincide with the left and right sides. Grain straw supplied from the end of the transport will be handed over to the takeover side transport chain side before the feed chain side on the stock side. As a result, there was a problem that the stock base part drooped downward and spilled downward without being inherited by Fidchen.

  An object of the present invention is to eliminate the above-mentioned problems, to improve the take-up and transport posture during long-running, and to prevent spillage during take-up.

In order to solve the above problems, the present invention has taken the following technical means.
That is, the invention described in claim 1 is a threshing on the stock side that takes over the cereal supplied from the supply chain (11) of the chopped cereal conveyance end of the reaping part (2) and conveys it to the threshing part (3). A feed chain (13) and a takeover conveying chain (14) located closer to the tip than the threshing feed chain (13) are provided, and the start end of the threshing feed chain (13) is connected to the start end of the takeover carrying chain (14). Also, it is a combine harvester cereal takeover transfer device characterized by being arranged on the upper side in the transfer direction.

  The cereals supplied from the supply chain 11 at the cutting cereal feed terminal are taken over by the takeover transport chain 14 and the threshing feed chain 13 of the threshing unit 3. At the same time as the hand over to the chain 14 or earlier, it will be handed over to the beginning of the threshing feed chain 13, and after the hand over, it will be lifted and transported in an orderly manner by the joint action of the handing over transport chain and the threshing feed chain. It is supplied into the handling room and threshed.

  As described above, since the inheritance of the cereal to the threshing feed chain 13 is inherited substantially at the same time as the inheritance to the continuation conveyance chain 14 or succeeds in advance, The base part hangs down and does not spill out, the transport posture is not disturbed, and the stocker side can be reliably received and transported in an orderly manner.

  The invention according to claim 2 is characterized in that the takeover conveying chain (14) has an inner chain plate (15) positioned on the side farther than the threshing feed chain (13) side and an outer side positioned on the side closer to the threshing feed chain (13). The combine plate according to claim 1, further comprising a chain plate (16), wherein the protrusion (15a) of the inner chain plate (15) is set higher than the protrusion (16a) of the outer chain plate (16). The harvested cereal takeover transfer device.

  The tip side of the grain culm that is handed over from the supply chain 11 to the hand-over transport chain 14 is reliably handed over while being lifted and transported as it is under the action of the high protrusion 15a of the inner chain plate 15. Therefore, the transfer from the supply chain 11 to the takeover / conveying chain 14 is carried out satisfactorily.

  According to the first aspect of the present invention, the threshing feed chain 13 is configured such that the starting end portion of the threshing feed chain 13 extends to the upper side in the conveying direction from the start end portion of the takeover conveying chain 14 and can be transferred by inheritance. The cereals can be handed over to the take-up transport chain 14 at substantially the same time or ahead of it, and even if the cereals are long, the stock base does not fall down and spill over. In addition, the transport posture is not disturbed, and the stockholder side can be reliably received and transported in an orderly manner.

  Further, according to the invention described in claim 2, while having the effect of the invention described in claim 1, the tip side of the cereal to be handed over to the take-up transport chain 14 is reliably lifted by the high protrusion 15a of the inner chain plate. It will be transported, and it is possible to reliably prevent slipping down to the stock market side and spillage toward the front end side.

An embodiment of the present invention will be described with reference to the drawings.
The combine mainly comprises a cutting part 2 at the front part of the vehicle body 1 that cuts and conveys napped grain straws and a threshing part 3 at the rear part of the vehicle body that threshs the grain straws that are conveyed and fed from the cutting part 2.

  The reaping part 2 is a weed body 5, 5, which splits the napped cereals left and right, a 6 siege raising device 6 that causes the cereals after weeding, and the cereals after raising. Harvesting clipper-type harvesting device 7, scooping and transporting device 8 that scoops and transports the harvested rice cake, and harvested and harvested rice cake that is taken up and transported to the rear threshing unit 3. A vertical cutting frame 17 which is composed of a conveying device 9 and can be moved up and down with respect to the vehicle body and provided along the front-rear direction, and a horizontal cutting frame 18 provided along the left-right horizontal direction at the front end of the vertical cutting frame. Equipped. On the terminal side of the harvested culm transporting device 9, a stock source side supply chain 11 and a supply chain 12 with a tip side lug are arranged up and down to feed the cereals to the threshing part 3 side through the depth adjusting chain 10. The threshing feed chain 13 of the threshing unit 3 is arranged and configured to inherit the culm with an appropriate posture.

  A takeover conveying chain 14 is provided on the grain tip end side of the threshing feed chain 13 that inherits and conveys the stock side of the grain straw and carries the grain straw from the supply chain 11. The relationship between the threshing feed chain 13 and the takeover conveyance chain 14 is that the start end of the feed chain 13 extends longer than the start end portion of the takeover conveyance chain 14 in the conveyance direction, and is transferred to the start end of the takeover conveyance chain 14. It is configured to take up and carry up the stock side of the cereals to be supported from below. Further, in the relationship between the takeover conveyance chain 14 and the supply chain 11, there is an arrangement relationship in which the end roller position of the supply chain 11 and the start end roller position of the takeover conveyance chain 14 coincide with each other in the front-rear direction. The cereals are handed over successfully. In the takeover conveyance chain 14, the protrusion 15a of the inner chain plate 15 located on the side farther from the threshing feed chain 13 side (supply chain 11 side) is (H) than the protrusion 16a of the outer chain plate 16 on the near side. It is made high by the minute upward so that the cereal can be successfully transferred from the supply chain 11 to the transfer conveyor chain 14.

  Since it is configured as described above, the grain straw supplied from the supply chain 11 of the harvested grain trough conveyance terminal part is handed over to the takeover transport chain 14 and the threshing feed chain 13 of the threshing part 3 in the harvesting operation. At this time, the stock side of the grain culm is handed over almost simultaneously with the handing over to the hand-over transfer chain 14 on the tip side, or is handed over to the start end of the threshing feed chain 13 earlier than that, and after handing over By the cooperative action of the takeover conveyance chain 14 and the threshing feed chain 13, it is lifted and conveyed in an orderly manner. The threshing process is carried out by a rotating barrel 19 that is fed to and rotated.

  As shown in FIG. 5, an elastically displaceable grain candy that holds a pressing force weaker than the clamping force of the clamping rail 13 a at the beginning of the clamping rail 13 a facing the upper side of the threshing feed chain 13. By providing the pressing spring 21, even a small amount of cereal can be smoothly nipped and conveyed without stagnation. In the example shown in the figure, the cereal pressing spring 21 is interposed between U-shaped sandwiching rails whose starting ends are curved upward (see FIG. 6), and the tip thereof is disposed on the upper surface of the threshing feed chain 13.
