Description

[Detailed description of the invention] Conventionally, in a combine harvester with three or more rows of cutting that is equipped with a plurality of grain culm pulling bodies and a plurality of subsequent grain culm raking paths, the harvested grain culm is raked in from one side and fed laterally. It is already known to guide the harvested grain culm, which has been raked in from the side, by means of a single guide rod when merging it.

However, since the guide rod only makes linear contact with the grain culm, it does not have the effect of correcting the disordered posture of the culm, and the grain culm that is raked into the grain culm that is transported laterally in a disordered posture. When the grains are fed to the threshing device, the culms often come off or break, and when the handling depth is adjusted, the conveyor claws of the horizontal conveyor chain collide with the guide rods. There were other problems.

The present invention aims to improve the above-mentioned drawbacks, and includes a plurality of grain culm lifting bodies installed obliquely in the front part of the cutting blade, and a plurality of grain culm lifting bodies extending rearward from the lifting path of the grain culm pulling bodies. a grain culm raking path, an ear conveying chain installed behind them, where the grain culm raking paths sequentially merge, and which has a large number of conveying claws and is movable up and down, and a stock side. In a combine harvester equipped with a pre-processing device consisting of a lateral conveying body consisting of a lateral conveying chain for conveying grains, and a grain culm conveying device extending from the end of the lateral conveyance to a threshing device, the grain culm raking path of the lateral conveying body is On the upper side of the merging region in the lateral feed direction, a flexible guide body in which a large number of synthetic resin wire members are arranged in a comb-teeth shape and substantially crosses the end of the grain culm raking path is installed on its guiding surface. is provided in a cantilevered manner along the culm direction of the grain culm.

The grain conveying device 10 includes an ear conveying chain 11 that extends from a horizontal conveying section at the front to a vertical conveying section toward the rear and has a large number of conveying claws, and a grain conveying chain 11 that extends from the end of the horizontal conveying chain 7 to a vertical conveying section toward the rear. The vertical shaft 13, which supports and drives the rear part of the conveyor chain 12, moves up and down about the horizontal axis P as shown in FIG. 1 to adjust the handling depth.

Reference numeral 14 denotes a guide plate which extends rearward from both rear sides of the intermediate grain culm pulling body 4, has a lower end along the case of the scraping chain 5b, and has a guide surface at the rear end that becomes the front surface of the lateral conveyance path. The outer surfaces thereof constitute one of the guide surfaces of the grain culm raking paths A and B, and the guide plate 16 protruding from the rear surface of the grain culm pulling body 4 on the left side constitutes the guide surface of one of the grain culm raking paths A and B. It constitutes the other guide surface, and its rear portion runs along the front surface of the rotating portion of the grain culm conveyance path.

The grain culm raking route A is the central guide plate 1.
4, it merges with the grain culm raking route A on the lower side in the lateral transport direction, and the guide plate 14
A comb-shaped flexible guide body 15 made of a flexible material made of synthetic resin is provided on the side of the confluence C at the rear of the grain culm raking path A while substantially crossing the rear end of the grain culm raking path A diagonally. Its tip partially enters the lateral conveyance path, and its guiding surface is attached in a cantilevered manner along the culm direction.

A star foil-shaped scraping wheel 17 is provided at the front left running portion of the stock conveyor chain 12, and the scraping wheel 17 is attached to the floating sprocket of the stock conveyor chain 12 as shown in FIG. 18, and is located between the stock conveying chain 12 and the ear conveying chain 11 as shown in FIG. The rear part of the guide rod 20 extends rearward from the left guide frame 20a along the left side stock transfer chain 6b, and the clamping rod 12 is provided opposite to the conveyance surface of the stock transfer chain 12.
While passing over the intersection with the front part of the grain culm, the stock base of the grain culm is transferred to the stock base conveying chain 12 and the clamping rod 12a.

In the above example, 3-row mowing was performed, but in 5-row mowing and 6-row mowing, the grain culm raking path is 3-row, and in 7-row mowing and 8-row mowing,
In row cutting, the number of rows increases by one more row.

In addition, 21 in the drawing is a guide rod whose front part is continuous with the guide culm, and which extends rearward along the right-hand stock head scraping chain 6b and then further along the lateral conveyance chain 7 to the merging part C. It is.

Next, to explain the action, the erect grain culm is divided by the weeding body 3, and one row of grain culm comes from the grain culm rake route B on the right side, and from the grain culm rake route A on the left side. Two grain culms are each raked by a belt 5
a, raking chain 5b, raking wheel 6a... and the stock culm raking chain 6b to the rear, and the grain culm raked from the grain culm raking route B on the right side is transferred to the horizontal conveyance chain 7.
The grain culm is transported horizontally by the grain culm raking path A on the left side, and the grain culm is raked in from the grain culm raking path A on the left side, and the grain culm is traversed through the rear part of the central guide plate 14 at its rear end. It joins the incoming grain culm.

At this time, the flexible guide body 15 is pushed backward and bent by the grain culm scraped in from the grain culm raking route A, so that the flexible guide body 15 further penetrates into the horizontal conveyance route, and is raked from the grain culm scraping route B. The grain culms that have been loaded and fed laterally are pushed while aligning the culm direction in the vertical plane and pushed into the base side of the conveying claws of the ear conveying chain 11, and the conveying claws are flexible guides by adjusting the handling depth. Even when the conveying claws are at the same height as the grain culm raking path B, the conveying claws smoothly pass between the synthetic resin wire members of the flexible guide body 15, and in any case, the grain culms from the grain culm raking route B are removed. is pressed against the base side of the conveying claw so that its tip protrudes, and securely locks the grain culms scraped in from the grain culm scraping path A, allowing them to merge in an orderly manner. While being prevented from falling forward at the rear of the plate 16, it rotates while being scraped by the scraping wheel 17, and the front part of the stock conveying chain 12 and the clamping rod 12a, as well as the ear conveying chain 11 and the guide rod opposite thereto. 11a.

When the grain culm is transported later, the handling depth of the grain culm is adjusted by tilting the grain culm conveying device 10 up and down, and then the stalk part is transferred to the feed chain 22 and the pinching rail 23 of the threshing device, and the ear part is transferred to the feed port. Insert it into the threshing process.

In this way, when one cycle of reaping is completed and the machine is rotated, at the end of reaping, the left and right grain culm raking paths A,
Since the grain culm raked from the right grain culm reaches the lateral conveyance route almost at the same time as the last grain culm raked from B, when the grain culm raked from the right grain culm raking route B passes through the confluence part C, the left grain culm raked The grain culms scraped from the feeding route A reach the confluence part C.
The flexible guide body 15 supports and guides the front side of the grain culm as it is being fed sideways, and prevents the grain culm from falling forward, falling out of the culm, and disturbing its posture. It can be horizontally conveyed and circulated in an orderly manner.

As described above, the present invention includes a plurality of grain culm lifting bodies installed obliquely in the front part of the cutting blade, a plurality of grain culm raking paths extending rearward from the raising path of the grain culm lifting bodies, and a tension extending behind them. A lateral transport body consisting of an ear transport chain which is provided and where the grain culm raking paths sequentially merge and which has a large number of transport claws and is movable up and down, and a lateral transport chain which transports the stock side; In a combine equipped with a pre-processing device consisting of a grain culm transport device extending from the end of the traverse transport to a threshing device, the grain A flexible guide body, in which a large number of synthetic resin wire members are arranged in a comb-teeth shape, substantially crosses the end of the culm raking path, is cantilevered so that its guiding surface is along the culm direction of the grain culm. Therefore, when the grain culm that has been raked from the grain culm raking route on the lower side joins the grain culm that has been transported laterally, the raked grain culm can be moved by moving the flexible guide body into the lateral transport route. Grain culms that are bent and transported laterally are pushed toward the base side of the claws of the lateral conveyor of the ear conveying chain while being aligned better across the rear guide surface, adapting to the difference in culm amount of the merged grain culms, and being raked. The grain culms can be guided by the front guide surface while reducing disturbance of the culm posture, and can be reliably locked by the tips of the conveying claws that protrude by the above-mentioned pushing and can be brought together in an orderly manner.

In addition, when the ear section conveying chain is moved up and down to adjust the handling depth according to the culm length of the grain, and the movement trajectory of the conveying claw overlaps with the flexible guide body, the conveying claw
The grains will pass between the synthetic resin wire members of the flexible guide that maintains a normal guide surface, and even in this state, grains with disordered postures on the rear and front surfaces of the comb-shaped flexible guide will pass through. It does not impair the effect of aligning the culms.
