Description

[0001]
[Industrial application fields]
The present invention relates to a combine transporting device equipped with a pre-processing device for harvesting and transporting cereal grains at the front of a traveling machine body equipped with a threshing device.
[0002]
[Prior art]
Conventionally, as is known in Japanese Utility Model Publication No. 62-164733, in order to widen the cutting width for intermediate cutting or cutting work, the gap between the side scraper wheel and the stock transport chain heading backward from the side , The front stockholder scooping chain facing obliquely outward and forward is arranged, and the above-mentioned stirring wheel, the front sprocket of the stockstock scavenging chain and the drive sprocket of the front stock stock scooping chain are directly connected to the same drive shaft. Combines arranged independently above are already known. In addition, it has already been proposed that the front stock and the stock chain are stretched around the same sprocket on the top of the stir ring.
[0003]
[Problems to be solved by the invention]
As is well known in Japanese Utility Model Publication No. 62-164733, a napkin cereal gruel is used in which a front strainer scooping chain heading diagonally outward and forward is disposed between a stirring wheel and a strainer scooping chain. Before being transported to the cutting blade position, the stock base close to the ground is forcibly transported diagonally laterally back by the front stock base scratching chain, so that the side tilt angle of the cereals increases and pushes down In addition to unsmooth transport, the rotating sprockets, the front sprocket chain drive sprockets, and the front sprocket chain sprockets and other rotating bodies are directly independent on the same drive shaft. Therefore, the sawdust and the like are entangled with the rotating shaft and often prevent smooth operation. In addition, as previously proposed, even in the case where the front stock former scavenging chain and stock stock scooping chain are arranged on the same plane as a series of chains, the cereals are conveyed to the cutting blade position in the same manner as described above. Before, the stock base part approaching the ground was forcibly transported backward by the scraping chain, so that the falling angle of the cereals became large, the phenomenon of pushing down occurred, the transport was disturbed, and there were many spills.
[0004]
[Means for Solving the Problems]
The present invention is equipped with a pretreatment device comprising a reaping device and a cereal conveying device for supplying the threshing cereal to the threshing device at the front of a traveling machine body equipped with the threshing device, and the reaping device is arranged in the lateral direction. Three or more scoring wheels that are arranged and have an interval between the one at the edge of the already-cut ground and the one inside thereof, and the stock stock scratching backward from the top of the scoring wheel In a combine composed of a cutting chain and a stalk-scratched body extending forward from the upper side of the stock source scooping chain, it was close to the upper surface of the front part of the stock base scoring chain at the end portion of the already cut yard by extending the front lines based scraping chains obliquely outwardly forwardly from the site, before Symbol scraping wheels, front sprocket strains based scraping chains, and the drive sprocket of the front lines based scraping chain holding tube Arranged on the transmission shaft supported by the The packet is brought close to the lower end of the holding tube while mounted on the lower portion of the transmission shaft, fixed to the front sprocket bets while loosely boss drive sprocket of the front lines based scraping chains at the bottom of the holding tube As a result, the above-mentioned problems have been solved.
[0005]
[Action]
When the combine equipped with a threshing machine is moving forward, in the case of half-splitting work and coasting work, on the side that becomes the pre-harvested land side in normal work, the front stock former scoring precedes the scrambling action of the stir ring The chain and stalk scoring belt scrape the stock base part and stem part of the napped cereals diagonally backward inward, and the scoring wheel and stock base scoring chain take over and scrape the cutting blade. At that time, since the front stock rake chain is arranged at the upper part of the stock rake chain, the upper part is locked rather than the lower part or the one stretched close to the upper surface of the take-up wheel. It can be passed on to the scraper wheel with less sideways falling down of the cereal, and can be cut with a cutting blade, preventing entanglement of the heel posture and spilling it can. At that time, since the boss of the drive sprocket of the front stockholder chain fixed to the upper surface of the front sprocket is fitted to the lower part of the holding cylinder, the transmission shaft is not exposed directly, Weeds and the like rotate around the holding cylinder at the top of the boss portion, and smooth operation is possible without being entangled with the transmission shaft.

【Example】
An embodiment of the present invention will be described with reference to the drawings. A reaping device 4 and a reaped cereal are supplied to the threshing device 1 at a front portion of a machine body 3 that performs reaping processing while being advanced by a traveling device 2 equipped with the threshing device 1. A pretreatment device 6 comprising a cereal conveying device 5 is attached.
[0007]
The reaping device 4 includes four weed bodies 4a having a wide cutting width only on the already-cut ground side, three culm raising bodies 4b, and a laterally arranged end-of-cut-ground side end. Three or more (three in this example) scraping wheels 7 in which the distance between the one and the inner one is wider than the distance between the other ones, and the strainer scraping from the upper part of the left and right scratching wheels 7 to the rear It is comprised by the insertion chain 8 and the stalk part raking body 9 extended diagonally forward so that the front part of the raking path may be expanded from above.
[0008]
The lower link plate 12 with the space between the front stocker-side scraper chain 10 on the already-harvested side (right side as viewed from the driver's seat A) is provided with a scraping claw 13 having a receding angle, When wrapping around at the rear end of the stock source scooping chain 10, the cereal grains that are being conveyed toward the rear are not scraped forward.
[0009]
The scraper wheel 7, the front sprocket 8 a of the stocker take-up chain 8, the V pulley 9 a and the drive sprocket 10 a of the front stocker take-up chain 10 are supported by ball bearings 14 b at the upper and lower ends in the holding cylinder 14. The boss portion 8b of the front sprocket 8a of the stock source take-up chain 8 is fixed to the lower portion of the transmission shaft 15 and is brought close to the lower end of the holding cylinder 14, so that The boss 10b of the drive sprocket 10a of the insert chain 10 is fixed to the upper surface of the front sprocket 8a in a state where it is loosely fitted to the lower portion of the holding cylinder 14. Further, the main body of the front sprocket 8a of the stocker take-up chain 8 and the drive sprocket 10a of the front stocker take-up chain 10 are made of a large-diameter sheet metal as shown in FIG. Since it is screwed directly to the flange portion 8c of the front sprocket 8a of the stocker take-up chain 8, it rotates in a large-diameter tube state and acts to prevent wrapping of swarf and the like of cereals.
[0010]
Further, the holding cylinder 14 is supported by a support arm 16 extending from the lower cutting frame, and a bracket 18 extending rearward from the holding cylinder 14 is attached to the idler wheel of the front stocker's take-up chain 10. 19 and the Tightener 20 of the front stock former take-up chain 10 are supported, and tension is applied to this chain drive system.
[0011]
When the combine equipped with the threshing device 1 advances the harvesting of the cereals in front of the machine body 3, in the case of the middle split work and the sieving work, it is required to cut the cereals for the machine width. In the case of a combine with a small width, it is necessary to scrape, cut and process cereals that are wider than the cutting width. First, the cereal that has been weeded by the cutting body 4a at the tip is caused to fall down by the next pulling device 4b. After being locked forward by the claw 13 of the front stocker's take-up chain 10 extending forward and being caught in a gentle inclined posture and cut by the cutting blade 4c, the The threshing device 1 is provided by a cereal carrying device comprising a rear stock carrying body 21 and a ear side carrying body 22 together with a harvested cereal that has been sent rearward by the stock former raking chain 8 and has been scratched from the other side. The tip is threshed and subjected to culling selection processing and culling discharge processing. At this time, the end of the already-cut-ground side is scraped with cereals having a width equal to or larger than the cutting width, but the stock is cut in a state of being gently tilted by the front stock-source scoring chain 10 at the upper position. Therefore, there is no pushing down and the cut of the cut is clean.
