Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly involves harvesting and collecting the shell culm, which has a short granulation length relative to the culm length, and then throwing the entire husk into a threshing room for threshing. This is a reaping/harvesting machine for threshing using a type of threshing device, and in detail, it is a reaping harvester that uses a self-propelled vehicle body to remove grains directly below or near the grain-bearing part of a planted stem culm that has a grain-bearing part above it. The present invention relates to a reaping harvester equipped with a reaping device for reaping crops and a collecting section for collecting harvested grains.

According to the above-mentioned reaping and harvesting machine, the planted shell culm, which has a short grain-bearing length relative to the culm length, is once harvested, and after a suitable period of time for drying, etc., it is threshed using a thresher type threshing machine. In this case, compared to the case where the culm harvested from the stock head is fed to the threshing machine for processing, there is no need to process the culm below the graining part as waste straw, and only the graining part is processed by the threshing machine. It is possible to process a large amount of shell culm in proportion to the load applied to the threshing machine, and to perform the threshing process with high efficiency. The grain part tends to sway, and it is difficult to efficiently and accurately cut the lower end of this grain-bearing part.
As described in Publication No. 7, when a rotary cutting blade that rotates around the horizontal axis is used to cut the granulation part, the position where the cutting blade acts on the culm is unstable, and the part in the middle of the granulation part is cut off. If the grain is harvested too much, there will be a lot of grain recovery loss.In order to minimize this recovery loss, the cutting blade's operating position should be set below the lower end of the granulation area, which will increase the amount of straw and make it easier to thresh. The load on the machine increases unnecessarily, making it impossible to perform threshing operations efficiently.

Therefore, in the past, a palligan type cutting blade was used, as described in, for example, Japanese Utility Model Publication No. 10632/1983.
In addition, a technique has been proposed in which a pulling device and a conveying device are sequentially provided in front of the harvester to reliably guide the granulation part to the blade of the harvester.

Although this configuration is effective in reducing the recovery loss of grain due to harvesting, the device itself for guiding and feeding the grain setting part in an appropriate posture for harvesting becomes complicated and large. , there is also the problem of disadvantages in terms of aircraft control. The present invention aims to solve the above-mentioned problems of the prior art, and by devising a conveying device that transfers the harvested granulation part to the collecting section, the position where the harvesting device acts on the culm is stabilized. The purpose of this invention is to make it possible to efficiently and accurately cut the lower end of the part where the grains are attached, and to make the structure for this purpose more compact.

The characteristic structure of the present invention for achieving the above object is as follows:
In the reaping/harvesting machine mentioned above, the reaping device is constituted by a clipper-type reaping device with a blade facing forward in the direction of movement of the self-propelled vehicle body, and the reaping device is configured to reap from a position immediately after the reaping device to the collecting section. A guide body that guides the grain-bearing part of the planted stem culm is extended, and further, the grain-bearing part of the planted stem culm is scraped and supplied to a position above the reaping device and the guide body toward the reaping device side. At the same time, the mower is rotated around a horizontal axis along the width direction of the vehicle body so as to transfer the cut grain part located on the guide body toward the collection part side, and a large number of The present invention is provided with an endless strip-shaped scraping and conveying device equipped with a scraping body, and this configuration provides the following effects.

That is, the harvested granulation part is transferred to the collection section by a guide body and a scraping body that is driven to rotate around the horizontal axis, and the culm to be harvested is introduced between the front and rear scraping bodies, and the culm is scraped. Since the clipper-type reaping device is operated in a position where the culm is sandwiched between the body and the reaping device, and the grain-bearing part does not swing, the lower end of the grain-bearing part can be efficiently and accurately cut from the working position of the cutting blade. Moreover, by using the scraping body as a component of both the conveying means and the scraping means, the entire structure could be made more compact.

Next, an embodiment of the present invention will be described regarding a two-row type reaping harvester.

As shown in Figures 1 and 2, a walking self-propelled vehicle body A has an engine 1, a pair of left and right running wheels 2, and a steering handle 3 that is approximately U-shaped in plan view. A clipper-type reaping device 4 that harvests a part of a planted stem culm that has a grain-bearing part above or near the grain-bearing part, and a collection part 5 that collects the cut grain-bearing part are arranged in the longitudinal direction of the machine. At the same time, the harvested grain part is conveyed between the reaping device 4 and the collecting section 5, and the conveyance starting end thereof is extended forward of the reaping device 4 to collect grains of the planted stems. Reaping device 4
A scraping conveyance device 6 is provided which also serves as a scraping device.

In addition, a grounding bridge body 8 that can be vertically swung and fixed via a turnbuckle 7 is provided at the center of the body width of the running vehicle body A, at the rear of the running wheels 2, 2. By vertically swinging the body 8, the position of the reaping operation by the reaping device 4 can be changed up and down using the ground contact portions of the running wheels 2, 2 or the axle axis center as a fulcrum, and the control handle of the running vehicle body A can be changed vertically. 3 is an operating lever 9 for a main clutch (not shown) interposed in the transmission mechanism from the engine 1 to the running wheels 2, 2, the reaping device 4, and the raking and conveying device 6.

The collection section 5 is composed of a collection bag that is removably locked and held between the operating handle 3 and the rear portion of a transport guide plate 11 as a guide body of the scraping transport device 6.

The transport device 6 is constructed as follows. That is, a driven shaft 15 and a drive shaft 16, which have pulleys 13, 13 and 14, 14 fitted around the left and right frame frames 12, 12 of the self-propelled vehicle body A, respectively, are attached to the conveyance guide. An endless belt 17, which is positioned above the plate 11 and horizontally hung at appropriate intervals in the front-rear direction, and stretched across pulleys 13, 14 and 13, 14 facing each other in the front-rear direction. 17, a plurality of bars 18 serving as scraping bodies for retaining and conveying the grains are installed at appropriate intervals in the rotational movement direction of the endless belts 17, 17, and the pulley 13 of the passive shaft 15
