に関するものである。[Detailed Description of the Invention] [Industrial field of application] The present invention conveys the whole amount of grain culms cut by the cutting and conveying section provided in the front part of the machine to the threshing section behind the cutting and conveying section for threshing processing. The present invention relates to a mowing and conveying section in a normal combine harvester.

る。The cutting and transporting section at the front of the machine lifts and conveys rice and other miscellaneous crops to the rear of the cutting machine and supplies all the harvested grain culms directly to the threshing section to perform threshing processing, and to remove foreign matter mixed in the sorting section. The mowing and conveying section of the ordinary combine for separating and collecting and collecting the grains is generally composed of a grass body, a grain culling reel, a cutting blade, a center scraping auger, a lifting conveying body and the like.

粒が飛散してロスとなる、等の問題があった。However, the cutting and transporting section of the conventional ordinary combine harvester has a rotation trajectory of the grain-scraping reel at the front of the machine and a rotation of the central scraping auger at the next stage that receives the grain stalks scratched by the grain-scraping reel. Since a mountain-shaped non-acting space that does not reach the path is inevitably generated between the locus and the locus, the grain culms are not delivered smoothly at this site, causing transfer leaks, and stagnant grain culms gathering at this site all at once. Then, it was transferred to the threshing section and supplied, and the threshing section was overloaded, and the grains separated from the culms at the central scraping auger section were scattered and lost, which was a problem.

いる。The present invention has been made in view of the above problems and has been made as an object to improve the problem. In the present invention, between the grain stalk reel and the central scraping auger, the delivery of the cut grain stalk between them is stagnant. With the aim of providing a mowing and transporting part in a normal combine harvester, which can be smoothly carried out without any trouble, can continuously transfer and supply grain culms to the threshing part, and can prevent scattering loss of grains separated in the central scraping auger part. There is.

とを特徴とするものである。The technical means adopted by the present invention in order to solve the above-mentioned problems are as follows: a grass body, a grain scraping reel, a cutting blade,
In a normal combine combiner equipped with a cutting and conveying section composed of a central scraping auger, a lifting transporter, etc., a notch is formed in a bottom plate located below an intermediate portion between the grain-culling scraping reel and the central scraping auger. Then, the forced transfer body rotating toward the central scraping auger is arranged in the cutout portion, and needle-shaped elastic projections are provided at desired intervals in the rotational direction on the entire peripheral surface of the forced transfer body facing the grain culm. It is characterized in that it is densely planted, and the earth and sand which has fallen between the projections when the grain culm is transferred is made to drop downward from the notch portion as the forced transfer body rotates.

した切欠き部から下方に落下させて排除される。Since the forced transfer body was provided in the intermediate part between the grain stalk scraping reel and the central scraping auger, the cut grain stalks sent to the non-acting space that does not pass the transfer action between them are forced by the forced transfer body. The grain culms are continuously transferred to the threshing section and fed to the central scraping auger, and the threshing section is not overloaded and the threshing efficiency is improved. Grains separated from the culms and scattered at the central scraping auger are also received by the forced transfer body and returned to the central scraping auger, so that loss of scattered particles is prevented. Further, the earth and sand mixed in the grain culm falls between the elastic body projections during the transfer by the forced transfer body, and the earth and sand are dropped and removed from the notch formed in the bottom plate as the forced transfer body rotates.

搬送部１後方の図示しない脱穀部に揚上搬送される。In the above configuration, the grain culm that has been scraped by the grass body 2 along with the forward movement of the aircraft and scraped by the grain stalk scraping reel 3 is cut off by the cutting blade 4 and placed on the bottom plate 9 of the cutting and conveying unit 1. Sent. Here, between the rotation locus 3a of the grain scraping reel 3 and the rotation locus 5a of the central scraping auger 5, there is a mountain-shaped non-acting space 8 that does not act as a hand-over action. Since the forced transfer body 7 is arranged so that the tip of the 7b can be seen through the window 9a of the bottom plate 9 and rotates toward the central scraper auger 5, the grain culm is forced by the elastic protrusion 7b of the forced transfer body 7. It is sent to the central scraping auger 5. The grain culm sent to the central scraping auger 5 is scraped in the central direction by the screw plate 5b, passed to the lifting transporter 6, and lifted and transported to a threshing unit (not shown) behind the cutting transport unit 1.
