Description

[Detailed description of the invention] This invention is a combine harvester in which the threshing section feed chain is installed along the longitudinal direction of the machine body, and the culm vertical conveyance is configured such that the conveyance end part can be adjusted in displacement along the transverse direction of the machine body. The present invention relates to a vertical shell culm conveying device equipped with a belt.

The above-mentioned shell culm vertical conveyance device changes the shell culm delivery position to the threshing section feed chain by adjusting the displacement of the conveying end of the shell culm vertical conveyance belt along the transverse direction of the machine. It is possible to change and adjust the handling depth in the threshing section depending on the length of the grain by adjusting the displacement of the vertical conveyance belt of the culm.

The purpose of this invention is to create a smooth conveying action according to the length of the husk in the husk vertical conveyance belt, which allows the handling depth in the threshing section to be changed according to the length of the husk. We have attached an auxiliary conveyance belt that can be adjusted to
It is an object of the present invention to provide a novel vertical conveyance device for shell culms in a combine harvester, which can carry out smooth conveyance according to the length of the shell culm.

Regarding the illustrated embodiment, the configuration of the vertical shell culm conveying device in a combine harvester according to the invention will be explained. As shown in FIG. The culm to be planted in the field is separated, and the planted culm is pulled up by the culm lifting device 3 installed at the front of the machine so as to be tilted diagonally backward and upward. A pair of conveyor belts 5 a ? which cut the planted culms at their stock bases with the blade 4 and join the stock bases of the cut culms at position A? The harvested husks are collected in a body-side amount by a lower conveying device 5 equipped with The culm is fed to the threshing section 8 by the vertical culm conveying device 6 and the ear conveying device 7, and the cut husk culm is fed to the threshing section 8 at the base of the stock by a feed chain 9 disposed on one side of the threshing section 8 along the longitudinal direction of the machine. Straw conveying device 1 that threshes while conveying and shifts the straw leaving the threshing section 8 toward the already cut field.
In a combine harvester configured to feed a cutter device 11 at 0, a control section 12 equipped with a passenger seat 12a is disposed on the other side of the front part of the machine body, and a paddy receiving section 13 is disposed behind it. This idea is implemented as follows.

That is, as shown in FIG. 2 and below, the culm vertical conveyance device 6 is a support frame 16 whose lower end is supported by a support stand 14 on the machine body via a crank 15. A support frame 16 that can be rotated along the transverse direction of the fuselage, a pair of sprocket wheels 17 and 18 that are rotatably supported at the lower and upper ends of the support frame 16, and both sprocket wheels 17. , 18, and a conveyor chain 19 with protrusions 19a suspended between the conveyor chains 1 and 18.
9 is provided along the upward running path of the conveyor chain 19, and is biased by a spring 21 to move in the direction of the conveyor chain 19, and transmits power to the sprocket wheel 18 at the upper end. The transmission case 21 and the supporting frame 16 or the conveying end side of the conveying device 6 are configured to be able to be displaced in the transverse direction of the machine body according to the length of the culm to be threshed in the threshing section 8. , this culm vertical conveyance device 6
In accordance with this invention, the following auxiliary conveyance belt 22 is further provided.

That is, this auxiliary conveyance belt 22 is a conveyance chain 22 with protrusions 22a that is suspended around a pair of sprocket wheels 24.25 that are rotatably supported at both ends of a short support frame 23 different from the above. However, the sprocket wheel 24 on the proximal end side is similar to the sprocket wheel 1.
8 is fitted onto the output shaft 21a of the transmission case 21, and the spline 26 is fitted onto the output shaft 21a of the transmission case 21, and is fixed onto the shaft 21a by a washer 27 and a nut 28.
8, then remove the sprocket wheel 24 together with the support frame 23 from the shaft 21a, change the phase appropriately, and fix the sprocket wheel 24 on the shaft 21a again. 23, and therefore the auxiliary conveyance chain 22, can be freely changed.

In the figure, reference numeral 29 denotes an auxiliary pinning rod provided along the culm conveyance path by the auxiliary conveyance chain 22, and this auxiliary pinning rod 29 is rotatably supported by the pinning rod 20 at 30. The proximal end is removably supported by the supporting metal fitting 31, and is urged to move in the direction of the auxiliary conveyance chain 22 by a spring 32 which rotationally urges the supporting metal fitting 31.

Further, 33 indicates sprocket wheels 24 and 25 for the auxiliary conveyance chain 22, which are supported by the supporting frame body 23.
This is a rod that prevents shell culm from rolling up.

The hull culm vertical conveyance device 6 according to this invention is constructed as described above, and when the hull culm to be threshed in the threshing section 8 is a short culm, as shown in FIGS. 2 and 5 a. The auxiliary conveyance chain 22 is used in a folded manner with respect to the conveyance chain 19. Conversely, in the case of a long culm, the auxiliary conveyance chain 22 is used as an abbreviation of the conveyance chain 19 as shown in FIGS. 3 and 5. It is used by positioning it on the extension line, and in this case, the vertical conveyance of the shell culm is facilitated as follows.

That is, in the posture of the auxiliary conveyance chain 22 at the time of short culm shown in FIG. 2 and FIG. Since the auxiliary conveyance chain 22 carries out the transfer and transfer to the feed chain 9, the transfer of the shell culm from the vertical conveyance device 6 to the feed chain 9 is carried out extremely smoothly. In the posture of the auxiliary conveyance chain 22 at the time of long culm shown in FIG. 3 and FIG. Since the part is largely moved outward from the machine body, that is, in a direction away from the flade chain 9, the length of insertion of the husk into the threshing part 8 after delivery to the feed chain 9 is made that much smaller, and the extra-long frame is This prevents the threshing depth in the threshing section 8 from becoming excessive even in the case where the grains are removed.

Note that the auxiliary pinning rod 29 has a shape that follows the auxiliary conveyance chain 22 in both cases by reversing its orientation in the cases of FIGS. 2 and 3 and supporting it on the supporting hardware 31. It's Toshide.

As described above, the culm vertical conveyance device in the combine harvester of this invention is configured such that the conveyance end portion can be adjusted in displacement along the transverse direction of the machine in a combine in which the threshing section feed chain 9 is installed along the longitudinal direction of the machine body. This is a shell culm vertical conveyance device equipped with a shell culm vertical conveyance belt 19, which includes a rotary wheel body 18 that supports the shell culm vertical conveyance belt 19 at its conveying end.
An auxiliary conveyance belt 22 whose one end is supported by a rotary wheel body 24 disposed on the same axis 21a as the auxiliary conveyance belt 22, which is configured to be able to change and adjust its inclination posture around the axis 21a,
It is connected to the husk vertical conveyance belt 19, so that when the culm is long, the husk culm can be delivered to the threshing part feed chain after being shifted in the direction of shallowing the handling depth in the threshing part by this auxiliary conveyance belt. Even in the case of extremely long culms, it is possible to achieve smooth vertical conveyance of the husk by keeping the handling depth constant in the threshing section, and conversely, in the case of short culms, this auxiliary conveyance belt can be almost The advantage of using it in an inclined manner along the threshing section feed chain is that the transfer of the husk culm from the husk culm vertical conveyance device to the threshing section feed chain can be made smooth and reliable.
