Abstract

PURPOSE:To enable to harvest buckwheat without lowering efficiency for harvesting soybean, etc., by disposing a guide member for pressing the stem straws of the buckwheat and ranged from the lower side of a reaping device to the front upper portion of the frame on the most front side of a reaping and pre- treating section. CONSTITUTION:A reaping-pre-treating section 2 comprising a rotary raking reel 3, a hair clipper type reaping device 4, an auger 5, a feed conveyor 6 for upwardly carrying grain straws, etc., is disposed on the front portion of a frame having a thresher thereon. A stem straw-pressing and guiding member 11 comprising a gently tilted lower side portion 11A acting on places where complicatedly entangled stems of buckwheat exist and which are positioned near the surface of the ground and a steeply tilted upper side portion 11B for dividing the grain- attached portions of the buckwheat whose stubs are separated form each other in an easily dividable state is detachably connected with bolts to a guide member 10A attached to the lower side of grass dividers 10 fixed to the right and left ends of a deck 12 covering an auger 5 in the pre-treating section 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a whole-culm input type combine harvester mainly used for harvesting buckwheat and soybeans.

[Conventional technology]

Soybeans were cultivated in relatively large numbers as a follow-up crop to rice or as a rotation crop, but buckwheat was cultivated at a smaller rate (and because the threshing method is similar to that of soybeans, it was traditionally cultivated. , were harvested using a soybean combine.

[Problem to be solved by the invention]

However, in recent years, there has been an overabundance of rice, and rice acreage reduction has been encouraged.
As an alternative crop to rice, not only soybeans but also buckwheat are being cultivated more frequently (as a result, the following inconveniences during harvesting have once again become an issue.

In other words, each soybean plant grows relatively independently, so the space between the plant heads is relatively transparent, so it is especially problematic to weed by inserting the front end of a sharp weeding tool into the space between the plant heads. However, in the case of buckwheat, the stems extend horizontally from near the base of the plant, creeping along the ground, and there are many stems intertwined between the bases of the plants, so it is difficult to use a weeding tool or a weeding tool. If an attempt is made to forcibly separate the grass using a reel or pulling device, the stems may be torn off or uprooted by the weeding tool.

Furthermore, if the base of the plant is within the cutting width, but the grain-bearing bone is facing outside the cutting width, the buckwheat crop cannot be harvested even if the stems are cut, and the harvested part of the buckwheat is left on the ground, causing workers to In some cases, farmers would pick up granulation bones left in the field after harvesting.

An object of the present invention is to enable a whole-culm input type combine harvester, which is mainly used for harvesting soybeans, to be able to be used for harvesting soybeans, etc. without reducing the harvest efficiency, and also for buckwheat without the above-mentioned problems. .

[Means to solve the problem]

A feature of the present invention is that a stem culm holding guide is provided on the most uncut side of the reaping pre-processing section, extending from the bottom of the reaping device to the upper front of the machine body.

[For production]

According to the above structure, the front part of the stem culm located on the uncut side of the cutting width of the combine is held down by the stem culm holding guide and guided to the lower side of the reaping device along the guide, so that the cutting Only the front part of the stem culm that falls within the cutting width will be cut.

〔Effect of the invention〕

Therefore, according to the present invention, buckwheat, which was conventionally difficult to harvest, can now be harvested without any problems using a soybean combine harvester by simply modifying the soybean combine harvester with the stem culm pressing guide.

〔Example〕

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

As shown in Figure 3, a full-culm input type combine harvester for soybeans and buckwheat is constructed by attaching a pre-harvesting section (2) to the front of the machine equipped with a threshing device (1) so that it can be raised and lowered. .

The reaping pre-processing section (2) includes a rotary raking reel (
3), a clipper-type reaping device (4), an auger (5) that collects the cut culm, and a feed conveyor (6) that sends the culm upwards.
), etc., and the harvested grain culm passes under the foot conveyor (6) and is sent from the grain culm discharge port (7) to the beater (8).
) onto the supply conveyor (9) and sent to the rear threshing device (1).

Next, the weeding mechanism at the front of the pre-reaping treatment section (2) will be explained. As shown in Figures 1 and 2, this weeding mechanism is
Stem culm presser removably bolted to the weeding tools (10), (10) provided at the left and right front ends and the guide member (11) attached to the lower side of the weeding tool (10) on the uncut side. It consists of a guide tool (11).

This guide tool (11) has a lower part (IIA) with a gentle slope that acts near the ground surface where the buckwheat stems are intricately intertwined.
It is divided into a front part where the bacterial strains are independent and easy to weed, and an upper part (IIB) with a steep slope where the weeds are separated, and rational weeding is performed.

The left and right weeding tools (10) are attached to a deck (12) that covers the auger (5) so that their positions can be changed around the horizontal axis, and the uncut side weeding tool (10) has its tip on the ground. By keeping it floating above the surface, the surface part (the stem part) can be easily guided to the lower side of the guide member (IOA).

In addition, when performing the mid-splitting work, use the weeding tool (10
), and by removing the guide (11) and lowering the tip of the weeding tool (10) close to the ground surface, soybeans can be harvested without any problems.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
