Description

[Detailed description of the invention] The present invention includes an upper and lower two-stage Q transport device consisting of an ear locking transport device and a stock clamping transport device in the transport path for transporting the cut husk in an upright position to the mounted threshing device. At the same time, the plant head clamping and conveying device is configured to be able to swing up and down about a horizontal rocking axis located at its conveyance start end, and the culm is transferred to the next subsequent clamping and conveying device. Regarding a handling depth adjustment device for a combine harvester, which is configured to be changeable in the direction of its culm length, thereby adjusting the handling depth, in detail, it is possible to adjust the handling depth by rationally improving the swinging structure of the stock clamping and conveying device. , the aim is to obtain a large range of handling depth in one stroke with a small amount of vertical swing.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The figure shows a combine harvester in which a reaping pre-processing section 3 is connected to the front part of a main body in which a threshing device 2 is mounted on a crawler traveling device 1.

The reaping pre-processing section 3 is connected to and supported by the main body so as to be able to move up and down freely around the horizontal axis X, and is forcibly moved up and down via a required drive device (not shown). three lifting devices 5a, 5b, 5c are arranged side by side in the lateral direction, and the rear portions of the lifting devices 5a, sb in the lateral and intermediate portions are connected and supported to the main body. Two upper and lower stages of scraping packers 7.7 and one stage of scraping packer 8 are arranged corresponding to the rear part of the lifting device 5c on the other lateral side. A stop conveyance vent 9 and a lower scraping packer 10 are arranged, a clipper-type reaping device 6 is arranged at the end position of the pulling path, and the clipper-type reaping device 6 has a horizontal feeding action at a position above the clipper-type reaping device 6. A starting end side portion of the stock head locking and conveying device 11 and a pair of ear tip locking and conveying devices bent in an L shape in plan view is disposed in circulation, and a terminal side portion having a backward-first rotation action of the ear tip locking and conveying device 12. Along the bottom of the stock clamping and conveying device 1
3 and the auxiliary stock holding and conveying device 14 are arranged in this order.

Then, while the culm pulled up by the pulling device 5a of the horizontal IRQ section is scraped backward by the scraping packer 7.7, the root end of the stock is harvested, and the root end of the stock is harvested. The locking conveyance device 12 is conveyed (in the lateral direction) in a state of support in two stages, upper and lower, with the starting end side portion, and the lifting device 5b of the intermediate portion is conveyed.
The culm pulled up is scraped backward by the scraping packer 8 while cutting off the base end of the plant, merges with the single conveyed culm that is being conveyed horizontally, and pulling up the other side of the lateral side. The culm pulled up by the device 5C is scraped backward by the two upper and lower locking conveyor belts 9 and the scraping packer 10, and the base end of the plant is harvested, and the culm is further removed from the culm of the two converged conveyor belts. At the same time, the merged three conveyor culms in the upright position are conveyed with the tip side being held in the tip side portion of the tip locking and conveying device 12, and the stem side is being conveyed with the tip side portion of the tip holding and conveying device 13. The stock is transported rearward in an upper and lower two-stage supported state in which it is sequentially held and transported by the auxiliary stock head clamping and transporting device 14, and at the end of transport, it is horizontally moved by the action of laying down the tip side of the ear tip locking and transporting device 12. It is configured so that the stock side is delivered to the feed chain 15 installed on the lateral side of the grain rolling device 2 in a reclined position.

As shown in FIG. 4, the stock head clamping and conveying device 13 is provided with a horizontal lateral support at a position that is on the conveyance starting end side and is offset toward the ear tip locking and conveying mechanism 12 side away from the clamping and conveying device 13. The terminal end side is configured to be able to swing up and down about the axis Y as a fulcrum, and the bi-folding link mechanism is interposed between the tip locking and conveying device 12 as the handling depth adjustment lever 19 swings. At the fourth bending and stretching, the transfer position of the conveyed shell culm from the conveyance end to the next auxiliary clamping conveyance device 14 is changed in the direction of the culm length, and the handling depth is adjusted. Accordingly, as shown in FIG. 5, the conveyance start position can be changed up and down as well as forward and backward.

In other words, compared to the case of a short culm as shown in FIG. At a point where the conveying force is weakened, the tip locking and conveying device 12 holds the culm, which has been conveyed a certain distance and has become slanted, near the lower end of the stock base, and when the culm is long, the culm is held in an approximately vertical position. It is configured to hold the culm at a higher position than when the culm is short.

In the figure, reference numeral 16 indicates a control seat provided at the front of the threshing device 2, reference numeral 17 indicates a grain bagging section provided at the lateral side of the threshing device 2, and reference numeral 18 indicates the control seat provided at the front of the threshing device 2. This is a waste straw processing device installed at the rear of the vehicle.

In summary, the handling depth adjustment device for a combine harvester according to the present invention has a head locking conveyance device 12 and a stock clamping conveyance device 1 in a conveyance path for conveying cut husk culms in an upright position to an on-board threshing device 2.
3, and the stock head holding and conveying device 13 is configured to be able to be vertically oscillated about a horizontal oscillating axis Y located at the starting end of the conveyance, The culm delivery position to the subsequent holding and conveying device 14 can be changed in the culm length direction, and the swing axis Y
It is characterized in that it is provided so as to be deviated from the stock head clamping and conveying device 13 toward the ear tip locking and conveying device 12 side.

That is, the clamping and conveying device 13 is swung up and down about a lateral rocking axis Y that is provided at the starting end of the conveyance and is offset to the upper side away from the conveying device 13. Therefore, as the terminal end side swings up and down, the conveyance start end side is also moved up and down, and this vertical movement amount can be effectively used for the handling depth adjustment amount, and the vertical movement of the conveyance start end side As a result, this conveyance starting end side will move to the upper conveying side and the lower conveying side.Using this, for example, as in the embodiment, when a long culm is produced, the stock end locking conveying device 11 and the starting end of this conveying device The culm is forcibly pushed from the conveying device 11 to the conveyance starting end while the culm is being conveyed to the tip side by the tip locking conveying device 12 without bowing. In addition, when the culm is short, the culm is actively separated from the starting end of the conveying device 11, and there is a delay until the culm is securely pushed into the starting end of the conveying device. During this delay time, the tip side is actively conveyed, and the culm J'' which is in a state where the stock end is delayed, is fully pulled out and conveyed to the tip side. The handling depth can be expanded by setting it to be clamped, thereby making it possible to adjust the handling depth over a larger range than the vertical swing amount of the clamping and conveying device 13. .
