Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grain culm scraping device in a harvester for cutting and binding or threshing grain culm.

[0002]

[Prior Art]

 Conventionally, it is already known to use a scraping belt with a flexible lug as a scraping device in a harvester that raises and scoops up napped culms, cuts them with a cutting blade, and binds or threshes the slashed culms. Has been.

[0003]

[Problems to be solved by the device]

 In the known harvester, the rear part of the scraping belt rotates away from the scraping path while rotating along the outer circumference of the pulley around which it is wound, and the flexible lugs protruding therefrom are also scraped. While rotating integrally with the belt, it rapidly turns and exits from the above-mentioned trapping path. At that time, the flexible lug is bent because it rotates backward while pushing the culm during scraping and conveying, and when it reaches the end of scraping, it stretches rapidly and swivels, so that the stalk that is caught is scratched. Since it bounces from the entrainment route, there were problems such as winding around the pulley when the posture of the grain culm was disturbed.

[0004]

[Means for Solving the Problems]

 The present invention mounts a threshing device on a machine stand equipped with a traveling device, and in front of the threshing device, a grain culm raising body, a cutting blade, a plurality of scraping wheels, a scraping body, and a slaughtered grain culm that has been scraped. A combiner is provided with a pretreatment device consisting of a grain culm transporting device for feeding the grain to a threshing device, and the scraping body is composed of a scraping belt with a flexible lug. By providing a stopper on the lower surface of this cover with which the flexible lug that exits from the scraping path comes into contact, when the flexible lug exits from the scraping path, the flexible lug is received by the stopper. The above-mentioned problem was solved by letting the robot escape from the scraping path along the length direction.

[0005]

[Action]

 In the process in which the scraping device scrapes the crop culm raised by the grain culm raising body backward, the cutting blades mow the culm grain raked from each scraping path and are bound by the binding device or the threshing device. Is transported to and processed for threshing. When the scraping belt of the scraping device scrapes the grain culm, the flexible lug is received by the stopper at the trailing end traveling portion and is largely deflected in the opposite direction to the rotation direction. Get out of. That is, since the lugs escape substantially along the length of the lugs without substantially turning, grain culms, straw debris, etc. are not scraped from the scraping path.
