Japanese Patent Application Laid-Open No. 2014-2223040

  Since the plate that covers the upper portion of the tine tin is not configured to cover the upper portion of the tine coil portion, the crop is caught between the plate and the tine coil portion, resulting in a head loss.

  An object of the present invention is to eliminate the above-mentioned problems by covering not only the upper part of the scraping tine but also the upper surface part of the coil part with a plate.

  In order to solve the above problems, the present invention has taken the following technical means.

  That is, according to the first aspect of the present invention, several scraping tines (3, 3) configured in a coil shape from reel slats (17) rotating around the rotation axis (Q) are directed downward at predetermined intervals. In the reaping device having the scraping reel (4) disposed on the belt, the strip-shaped covering plate (18) covering the upper portion of the scraping tine (3) is covered at least to the upper surface of the tine coil portion (3a). The reaping device is characterized in that it is configured accordingly.

  The invention according to claim 2 is the reaping device according to claim 1, wherein the covering plate (18) is formed by bending a front side end face of the tine coil portion (3a) downward.

  According to a third aspect of the present invention, a strip-shaped scattering prevention body (20) having flexibility is provided on the scratching action side of each of the scratching tines (3, 3). The reaping device according to Item 2.

  The invention according to claim 4 is a transparent member in which the anti-scattering body (20) is formed in a shape having an upper and lower width such that the lower end of the rake tine (3) is exposed downward, and the front can be seen through. The reaping device according to claim 1 or claim 2 or claim 3 configured.

  According to invention of Claim 1, the coating | coated plate (18) which covers the upper part of each rake tine (3, 3) prevents the catch of the crop between a reel slat (17) and an rake tine (3). As well as being able to cover the top surface of the tine coil part (3a), the crops at the time of scraping are not caught between the covering plate (18) and the tine coil part (3a), thus reliably preventing head loss. Can do.

  According to invention of Claim 2, in addition to the effect by the invention of Claim 1, the covering plate (18) not only covers the upper surface part of the tine coil part (3a) but also the tine coil part (3a). By folding the front side end face downward, it is possible to reliably prevent the crop from winding and intrusion on the tine coil portion (3a).

  According to invention of Claim 3, in addition to the effect by the invention of Claim 1 or Claim 2, the crop at the time of a squeezing action scatters forward from between each tine by a scattering prevention body (20). Can prevent falling. In addition, since the scattering prevention body is flexible, such as an elastic material such as cloth, vinyl, or rubber, the crop is not forcedly pressed, and the scattering fall of the grain is reduced and the cutting table is reduced. It is possible to eliminate the upward loss.

  According to invention of Claim 4, in addition to the effect by the invention of Claim 1 or Claim 2 or Claim 3, since the lower end of the scraping tine (3) is exposed below the scattering prevention body. The anti-scattering body (20) is made of a transparent member, so that the scratching action can be reliably and satisfactorily performed, so that the front visibility is good and the state of the scratching work can be easily confirmed, and the work efficiency can be improved. it can.

  An embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a general-purpose combine equipped with a scraping reel for scraping crop stalks such as paddy rice and rapeseed raised in the field. The front side of a vehicle body 1 having a traveling crawler 2 at the bottom is a crop. A scraping reel 4 provided with a scraping tine 3 for scraping the stems backward, a clipper-type horizontal cutting blade device 5 for cutting the stems after scraping, and a stem 6 after cutting are scraped onto the table 6 A pre-cutting processing unit 8 including a scraping auger 7 and the like is provided.

  In the feeder house 10 equipped from the left side to the rear side of the pre-cutting processing unit 8, the feed conveyor 11 that inherits the crop stalks from the pre-cutting processing unit, lifts and conveys the crops up and feeds them into the threshing unit 9. Is equipped. A driving operation unit including a driver's seat 12 and an operation box 13 is installed in the cabin 14 on the right side of the feeder house 10.

  A Glen tank 15 is provided behind the cabin 14 to temporarily store the harvest.

  Explaining about the take-up reel 4, on the reel slat 17 of the reel shaft 16 rotating around the rotation axis Q, several take-up tines 3 having coil portions 3a formed in a coil shape are attached at predetermined intervals. Each scraping tine is configured such that its base (upper end) side is attached to the reel slat 17 and the front end (lower end) side is in a downward state, and is rotated and transferred in a state where it always keeps a hanging posture. Yes.

  A strip-shaped covering plate 18 that covers the upper portion of the driven tine is attached to the reel slat 17 via a mounting bolt 19 so as to sandwich the upper portion of the driven tine from the front side. The covering plate 18 includes a coil covering portion 18a so as to cover not only the upper portion of the tine 3 but also at least the upper surface portion of the tine coil portion 3a, and the coil covering portion 18a has an end face 18e on the front side of the coil portion 3a. It is formed to be bent downward.

  As shown in FIG. 5 and FIG. 6, a flexible strip-like splash made of elastic material such as cloth, vinyl, rubber, etc. The prevention body 20 is stretched. In addition, the scattering prevention body 20 is formed of a transparent member having a vertical width such that the lower end of each of the scraping tines 3 is slightly exposed downward, and the front can be seen through.

  In the embodiment shown in FIG. 7, there is provided a cutting uppermost stopper 21 for fixing the uppermost cutting that can be swung up and down around the mounting portion of the upper and lower cutting cylinders provided on the lower side of the feeder house 10 of the cutting portion, and The fixed point stop stopper 22 that is fixedly held in a state where it is lowered to an appropriate cutting height is provided inside the maximum cutting stopper 21 in a double configuration.

  According to the above configuration, the fixed-point stop stopper can prevent the cutting portion from being lowered too much due to an erroneous operation during the cutting operation, so that it is possible to prevent plunging into the ground and scooping up mud. If the receiving side of the fixed-point stop stopper 22 is configured so that the amount of cutting up and down can be adjusted by the tightening amount of a bolt or the like, the cutting height can be adjusted to the operator's preference.

  The embodiment shown in FIG. 8 shows a configuration example of a threshing portion (threshing device) 9 for a general-purpose combiner, but the rear wall plate 25 at the rear portion of the handling cylinder (rotor) 24 is lower than the conventional vertical surface. By adopting the inclined surface 25S configuration that extends rearward as much as possible, there is no clogging of straw scraps, and the guide is quickly dropped down. Moreover, the cutting action of the straw by the chopper can be reliably performed by adopting a configuration that comes before the top dead center of the outer peripheral locus of the rotation group 7 of the chopper 26 on the inclined extension line of the inclined surface 25S.

  As shown in FIG. 9, a rubber sag is provided between the terminal end of the feed conveyor 11 and the inlet receiving plate 28 into the threshing chamber. If crops accumulate on this rubber sag, The tip turned up and a crease leaked between the rubber sag and the entrance plate. In this example, as shown in FIG. 10A (reaching state of the cutting part), B (reaching state of the cutting part), it is constituted by the leaf spring 30 instead of the conventional rubber sag, regardless of the raising and lowering of the cutting part. The leaf springs are constantly bulleted on the entrance receiving plate, so that even if crops accumulate, they do not turn over and can prevent leakage.
