Description

[Detailed description of the invention] During reaping work, the combine harvester runs with reference to the planted culm that is introduced into the lifting device at one end in the width direction of the machine body.

Therefore, if we consider, for example, that there is variation in the row spacing of the planted shell culms, the culm on the opposite side to the above reference will be displaced in the width direction of the machine body relative to the combine, and each planted shell culm will be introduced. A combine harvester with equal path widths may not be able to tolerate this displacement.

As a means to solve the above problem, the cutting width of the combine remains the same, the total width of each planting culm introduction path is the same as above, but the width of the path on one end is narrowed, There is a combine harvester having the above-mentioned structure in which the width of the path on the other end is widened, the wasteful path width of the path on one end is transferred to the path on the other end, and the tolerance of the displacement at the other end is expanded.

Also, at this time, if the plant receiving the pulling action is too close to the outer edge of the machine in the wide other end path, the base of the culm will be pulled up into a sleeping position crawling on the ground and will be harvested as it is. , the cutting height may be uneven compared to other culms, so after the lifting action, move the base of the grain culm outward to the side of the aircraft again and try to harvest while standing near the base of the grain. The following combine pretreatment device has been considered.

That is, at the rear of the lifting device installed corresponding to each of the plurality of planted shell culm introduction paths, there is a lateral conveying device that collects the shell culm raised by each lifting device at the center of the width of the machine body, and a lifting device. a reaping device for cutting the stock base of the perilla culm, and the horizontal conveyance device is configured with a stock base horizontal conveyor and a tip horizontal conveyor; The width is small, the width of the other end side path is large, and the pulling device is installed in the other end side path with the pulling action part facing inside the body, and the tip of the ear is A correction tool that guides the vicinity of the base of the raised shell culm planted at the outer end of the fuselage body at a position lower than the horizontal conveying body within the width of the other end side path, and this correction tool A pre-processing device for a combine harvester is being considered, which is equipped with a vertical conveyance device that forcibly conveys the guided planted culms toward the horizontal conveyance device.

The present invention relates to a pre-processing device for a combine harvester having the above-mentioned configuration, and by adding a simple structure, the grain culm conveying action by both the vertical conveying device and the horizontal conveying device can be ensured and smoothly. The purpose of the present invention is to provide a combine pretreatment device that can perform the pretreatment of a combine harvester well.

The present invention provides the above-mentioned combine harvester pretreatment device,
A series of conveyance guides extending from the correction tool to a vertically intermediate position between the vertical conveyance device and the ear tip horizontal conveyance body continuously along the conveyance path of both the vertical conveyance device and the ear tip horizontal conveyance body. is its technical feature, and this feature provides the following effects.

In other words, although it is a simple structural improvement of just extending a series of conveyance guides from the correction tool, it is possible to ensure that the vertical conveyance of the shell culm by the vertical conveyance device and the horizontal conveyance of the shell culm by the horizontal conveyance device are carried out reliably. Not only is this possible, but the culm receiver at the intersection of both conveyance devices can reliably and smoothly transfer the culm to the side of the lateral conveyor, without the culm getting caught or stagnating at the transfer point. .

Moreover, while the tip side of the planted culm guided by the correction tool is guided by the guide, the stem portion below the guide is forcibly transported by the vertical transport device.
This prevents the planted culms from accidentally detaching from the vertical conveyance device.
It has now become possible to transport this planted shell culm to the horizontal transport device while reliably and effectively raising it.

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

Fig. 1 shows a riding type combine harvester for two-row cutting, in which a threshing device 1 is mounted on a tower, in front of a machine frame 2, and pulling devices 3, 3' are arranged facing each other at appropriate intervals in the left and right lateral directions.

The width 11 of the path A located on the opposite side to the side where the threshing feed chain 6 is present is made larger than the width 2 of the other path A'.

The horizontal conveying devices 4, 4' are horizontal conveying bodies 4 having horizontal conveying claws 4a, 4a' which can be raised and lowered and which engage with the side of the stem of the culm.
A, 4A' and horizontal conveying claws 4b, 4 that engage with the tip side of the culm.
b', and the reaped husk culm conveying device 7 is composed of a head-end lateral conveyor 4B, 4B' having a tip side conveying body 4B and 4B'. It is composed of a tip locking and conveying body 7B that locks and conveys the tip of the culm.
