あつた。[Detailed Description of the Invention] The present invention relates to a wrapping prevention device for a grain culm conveyor. In grain culm reapers such as combine harvesters, it is known that a grain culm conveying body consisting of a conveying chain with projections is disposed in the pre-processing section in order to transfer the grain culm cut by the cutting blade section to a lifting conveyance device. However, in this type of grain culm conveyor, weeds, straw, etc. are carried along with the grain culm by the protrusions of the conveyance chain, and they tend to get wrapped around the drive chain wheels of the conveyance chain and rotating parts in the vicinity. This tendency is strong in those in which the driving chain wheel is engaged with the conveying surface of the chain. Therefore, it has been proposed to provide a scraper near the drive chain wheel in order to prevent weeds and the like from becoming entangled. However, conventional scrapers are installed integrally from the fixed side without considering the movement of the tension wheel installed close to the drive chain wheel, so when the chain is extended, the chain approaches the scraper. The weeds, straw, etc. that were scraped off by the scraper could not be reliably removed in the direction away from the drive chain wheel by force with the chain, so they were re-rolled. There were some drawbacks such as sticking.

提供しようとするものである。 The present invention was developed based on the above-mentioned circumstances, and consists of a grain drive chain for driving a conveyance chain that meshes with the conveyance surface of the chain, and a tension wheel provided in the vicinity of the drive chain. In the culm conveyor, the proximal boss portion of the tension arm that supports the tension wheel is loosely fitted into the bearing portion of the drive chain wheel, and the boss of the tension arm is positioned on the back side of the chain winding portion of the drive chain wheel. By extending the scraper integrally from the section, the opposing angle between the conveyor chain and the scraper can be maintained at a constant angle regardless of the movement of the tensioner due to the expansion and contraction of the conveyor chain. It is possible to forcibly and smoothly remove straw waste such as hakama and hakama in the direction away from the drive chain wheel using the conveyance chain, thereby preventing weeds, straw waste, etc. from wrapping around or clogging the drive chain wheel. It is an object of the present invention to provide a wrapping prevention device for a grain culm conveying body that reliably prevents this.

詰りを確実に防止することができる。 In the configuration as described above, straw waste such as weeds and grain hakama carried around by the protrusion 1a of the conveyance chain 1 during the reaping operation passes through the meshing part with the drive chain wheel 5, and then
Due to the rotational force of the drive chain wheel 5, the weeds try to get caught in the shaft 7 etc. that protrudes from the gear case 6, but these weeds etc. hit the scraper 10 located on the back side of the chain winding of the drive chain wheel 5 and are swept away. I get kicked. The weeds, straw, etc. swept away by the scraper 10 are caught on the protrusion 1a of the conveying chain 1 and are forcibly removed in the moving direction of the chain 1, so that the weeds, straw, etc. It is possible to reliably prevent the wrapping and clogging of etc.

等の排除作業は極めて円滑に行なわれる。 Incidentally, the scraper 10 faces the chain 1 at an opposing angle α to the boss portion 8'a of the tension arm 8' which is rotatably fitted loosely into the bearing 5' of the drive chain wheel 5.
Even if the chain 1 is extended and the tension wheel 8 is moved, the scraper 10 will rotate integrally with the tension arm 8. As a result of the fact that the angle α with respect to the chain 1 is always maintained at a constant spread angle without becoming a scissor angle or widening too much due to the movement of the tension wheel 8, the work of removing weeds etc. by the chain 1 is performed extremely smoothly.

のである。 As described above, the present invention provides a grain culm conveying body in which a drive chain wheel for driving a conveyance chain is engaged with a conveying surface of the chain, and a tension wheel is provided in a position close to the drive chain wheel. The base end boss part of the tension arm that supports the tension arm is loosely fitted into the bearing part of the drive chain wheel, and the scraper is integrally extended from the boss part of the tension arm located on the back side of the chain winding part of the drive chain wheel. Because of this design, the opposing angle between the conveyor chain and the scraper can always be maintained at a constant angle regardless of the movement of the tensioner due to the expansion and contraction of the conveyor chain. It can be forcibly and smoothly removed in the direction away from the drive chain wheel, and reliably prevents weeds, straw, etc. from wrapping around or clogging the rotating parts near the drive chain wheel. This makes it possible to maintain the transporting action of the grain culms well at all times.
