Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a grain culm raking device such as a reaper.
Can be used in the reaping section of combine harvesters, binders, etc.

PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION In a grain culm raking device that uses a raking body to rake the grain culm cut by a cutting blade device or the like backwards, generally the top and bottom of the culm Entanglement prevention guide members are provided on both sides, and the gap between the entrainment prevention guide members and the raking body is narrowed to prevent grain culms from being engulfed, but a large amount of straw waste etc. is generated near the raking body. However, this straw debris gets caught in the upper part of the lower entrainment prevention guide member and is pushed out to the end side, causing accumulation of straw debris at the end attachment part of the entrainment prevention guide member and causing a blockage. Easy to occur.

Therefore, the present invention aims to move the terminal ends of the entrainment prevention guide members provided on both the upper and lower sides of the scraping body forward and backward in the straw waste extrusion direction.
jB, and the space between the upper and lower entrapment prevention guide members at their terminal ends is widened to prevent clogging with straw debris. .

Means for Solving the Problems This invention provides a guide member (2) for preventing entanglement that is provided along both upper and lower sides of a scraper (1) that scrapes grain culms while rotating.
, (3) The configuration of a grain culm raking device such as a reaper, in which the terminal end of the raking body (1) is moved back and forth in the straw waste extrusion direction outside the rotation range of the raking body (1) and is attached to the machine body. do.

Functions and Effects of the Invention The rotating scraping body (1) scrapes and conveys grain culms rearward by this rotation. In addition, entrapment prevention guide members (2) and (3) provided along both upper and lower sides of the raking body (1) prevent grains from being engulfed by the raking action caused by the rotation of the raking body (1). This entanglement prevention guide member (2), (
3), and the grain culm raking action is performed by the cooperation of the raking body (1) and the entrainment prevention guide members (2) and (3).

During this grain culm raking action, some of the straw waste generated near the raking body (1) is removed from the upper and lower entrainment prevention guide members (2).
), (3) due to the flow of straw debris and grain culms that are successively generated while being caught on the upper edges of each, and the grain culms that are raked by the raking body (1),
The straw waste is pushed out to the terminal end of the entrapment prevention guide members (2), (3), and the straw waste is pushed out to the end of the entrapment prevention guide members (2), (3), which are attached to the front and back. One side is open at the end, and the space between the upper and lower ends is widened.
As a result, the straw debris can be pushed out of the rotating range of the scraper (1) and dropped without causing the straw debris to become clogged by the bridge or the like.

Each grain culm engaging portion (21) (:)3
), the grain culm engaging part (21) is guided along the guide plate (22) while rotating outward, and the grain culm engaging part (23) is rotated inward. Meanwhile, the grain culm engaging part (23) on one side is guided along the entanglement prevention guide member (2), and the grain culm engaging part (23) on the other side is guided along the stock base guide (27). The guided grain culms are both raked and transferred between the raking star foil (20) and the raking body (1), and merge in the center to form the raking body (1) (1). ) is engaged between the grain culm engaging parts (23) and (23), and is transferred to the stock head conveyance cheno (29) and ear tip conveyance cheno 7 (30) on the rear side, and is conveyed to the rear of the machine in an almost horizontal position. I changed it, passed the uke to Feetchen (28), and changed it to Feetchen (28).
28) transfers and supplies the grain culms to the threshing device (6), where threshing and sorting processing is performed, and the combine operation for continuous harvesting processing is advanced.

Also, in this combine harvester operation, the scraped star foil (
2G) (20) and the raking body (1) Some of the straw debris generated during grain culm raking action by the (1) or cutting by the cutting blade device (1B) is removed by the entrapment prevention guide member (2 ), (3) and are pushed out of the rotation range of the rake body (1), but when the rake body (1) engages to rake the grain culm, the entrainment prevention guide member (2 ), (3) The straw debris caught in the upper part is removed by the straw debris generated in sequence and the flow of the grain culm that is raked by the raking body (1), and is removed by the entrapment prevention guide members (2), (3). , the entrainment prevention guide member (3) extends to the discharge side, and the mounting stay (2B) is moved out of the rotating range of the scraper (1) for 16 it! Since the guide member (2) and the guide member (3) for preventing entrainment are provided with a wide space between them, the guide members (2) and (3) can be discharged without becoming clogged.
