Was known.

[0003]

In the conventional structure, the transfer floor of the transfer cylinder has a large number of holes of a certain size smaller than the size of paddy or wheat. There is a disadvantage that it is not possible to select leakage of foreign substances of different sizes when transferring large large grains and small grains such as paddy or wheat, and work for small grains such as rice and wheat and large grains such as soybeans. It had a structure that could not be harvested. That is, when harvesting and transporting large grains such as soybeans, even if foreign substances that are slightly smaller than the grain size of the grains are selected and released, only foreign substances smaller than the grain size of small grains such as paddy and wheat can be released. There was a flaw.

[0004]

In order to solve the above-mentioned problems of the conventional apparatus, the present invention is equipped with a thresher 2 for threshing and selecting a mixed cut of a cut culm and its grain.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 is a vehicle body having traveling crawlers on the lower left and right sides. A thresher 2 is mounted on the vehicle body 1, and a cabin 3 for the driver's seat, which is internally equipped with a seat, a control device and the like, is provided on the right front part of the thresher 2.
Reference numeral 4 denotes a cutting and conveying device that cuts and collects the grains growing in the field and conveys and collects them into the handling room of the thresher 2.

The cutting and conveying device 4 will be described in detail. On the front side of a long left and right gutter 5 having an arcuate inner peripheral surface, the grain stem side of grains such as rice, wheat or soybean grown in a field is placed. A cutting blade device 6 for cutting is provided, and a transfer spiral device 7 in which a spiral is formed on the surface of a cylindrical body is fitted and supported in the trough 5 so as to be appropriately transmitted and rotated. The transfer spiral device 7 is configured to transfer the cut matter from the left and right sides toward the center side and collect the cut matter at an appropriate intermediate portion of the gutter 5. A scraping rotor 8 is provided for scraping the cuts collected by the inger mechanism and the rotary lug device rearward.

At the portion of the trough 5 where the harvested matter is collected, a transport cylinder frame 9 for transferring the harvested matter to the threshing device is formed in an inclined state toward the rear upper side.
The transport cylinder 9 has a square cross section, and the bottom surface of the inner wall thereof is formed into a flat floor surface 9a. Reference numeral 10 denotes a scraping and conveying device, which is composed of an endless belt with a conveying lug that travels close to or slidably contacts the floor surface 9a of the cylinder frame 9 and scrapes up the harvested matter. The endless belt 10a has a lower rotating wheel and an upper portion. The endless belt 10a is provided with a lug 11 for scraping up the cut matter which is wound between the rotary wheel on the side and is rotated in the direction of the arrow (a), and approaches or slides on the floor surface 9a. . A bottom plate 22 having an elongated hole 12 in the vertical direction, which is narrower than the grain size of soybeans, is formed at a proper position on the lower side of the inner peripheral bottom surface of the cylindrical frame 9. Further, a back plate 14 having a small hole 13 to be superposed on the floor plate 22 is detachably provided on the back surface of the floor plate 22. The small holes 13 formed in the back plate 14 are such that rice grains and barley particles do not leak, and the small holes 13 are not necessarily provided. The point is that the back plate 14 can prevent the paddy and wheat from leaking through the long holes 12.

The blind plate or the back plate 14 on the lower surface side having the small hole 13 is rotatably provided with the upper rear side of the bottom surface of the cylinder frame 9 as a fulcrum, as shown in FIG. A lever-1 provided with a scratch metal fitting 15 on the outer surface of the cylindrical frame 9.
It is convenient if 6 is provided so that the hook portion 14a integral with the back plate 14 can be engaged and disengaged to open and close. Further, a suitable position of the bottom surface portion of the tubular frame 9 is opened, and a rotary bottom frame 19 that can be fitted into this opening portion is provided. A back plate 14 having a blind hole or a small hole 13 on the lower side can be superposed and fixed by a metal fitting 17 and a bolt 18, and the rotating bottom frame 19 can be fixed to the cylinder frame 9 by a bolt 20. At the time of soybean harvesting, the lower bottom plate 14 is removed so that foreign matter having a size of paddy or wheat can be removed by leakage, or at the time of harvesting rice or wheat.
It is even more convenient to inspect and clean the inside of the cylinder frame 9 by stacking the above to make it possible to prevent paddy and wheat from leaking.

The specific size of the hole 12 is such that the width of the long hole is 4 mm and the width of the hole 12 is 40 mm toward the transfer direction (a).
Generally, the horizontal pitch is 10 mm and the transfer direction pitch is 5 mm. Incidentally, reference numeral 21 in the drawing is a trigger reel. According to the configuration of the above example, the grain rod cut by the cutting blade device 6 enters the trough 5 and is transferred to a proper position near the center by the transfer spiral device 7 and is scraped up by the rotating body 8 and is conveyed by the conveying device. 10
Is scraped up along the upper surface of the bottom plate in the tsu barrel frame 9 and supplied to the handling room of the thresher 2 for threshing. In this case, when the harvested grain is soybean, the back plate 14 with the small holes 13 is rotated downward to be removed or removed. Then, foreign substances smaller than soybeans fall from the long holes 12 as they are during the transfer, and these extraneous substances are not thrown into the handling chamber, so that the threshing performance is improved. Next, when harvesting rice or wheat, grain of paddy or wheat falls from the long holes 12 and becomes a loss, so the back plate 14 is polymerized and fixed. Then, since grains of rice and wheat do not leak from the small holes 13, there is no fear of loss, and since the uneven portion is formed due to the relationship between the upper long hole 12 and the lower back plate 14, the rice sticks to the rice. The branches and hairs of the rice can be removed and the shedding function can be improved, and the selection in the thresher part becomes good.

[0010]

According to the present invention, when a large grain crop such as soybean is harvested and a small grain such as rice or wheat is harvested, foreign matter smaller than the grain size is removed by the cutting device 6. It is possible to remove the cut material that has been pruned in the middle of carrying it in the handling room, and the floor plate 22 side having the long hole 12 slightly smaller than the large grain such as soybean is always operated during the harvesting work. By adopting a means for attaching / detaching the back plate 14 side which overlaps with this lower side, the switching can be simplified, and in harvesting rice, the long hole 12 and the back plate 14 are used.
Since the unevenness is formed on the bottom plate in relation to the above, the branches and hairs attached to the paddy can be removed by these unevenness, and the shedding function can be improved and the sorting performance can be improved.
