Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a harvested culm collecting and feeding device for combine harvesters.

[Problems to be solved by conventional techniques and devices]

In the technology disclosed in Japanese Utility Model Laid-Open No. 60-144822, the plurality of sweeping fingers are arranged in the same direction as the rotation axis of the sweeping rotary member, and therefore, the feeding action of feeding the grain culms to the rearward conveyor direction. Is extremely weak, and if a large amount of grain stalks are thrown in, there is a risk of clogging near the rear conveyor entrance.

In the technique disclosed in Japanese Utility Model Publication No. 57-187031, the fingers are arranged in the same direction as the grain culm feeding action of one of the spiral blades arranged on the left and right with respect to the traveling direction. Since the grain culms are arranged in one direction with respect to the traveling direction, smooth transportation cannot be expected and there is a risk of jamming.

In the technique disclosed in Japanese Patent Laid-Open No. 60-41410, the arrangement of the feeding projections is biased to the right with respect to the traveling direction at the opening of the elevator behind the rotation direction of the auger, so smooth transportation can be expected. It may get stuck.

[Means for Solving the Problems] The present invention takes the following technical means in order to solve the above problems.

That is, on the peripheral surface of the collecting cylinder 3 that collects the grain culms that have been axially rotated over the cutting width and cut by the cutting blade device 1 on the front side to the conveying port 2 on the rear side, inward inward directions from both left and right sides. Left and right spirals 8 and 8 for collecting and feeding, and scraping fingers 4 that oppose the transport port 2 and scrape the transport culm into the transport port 2 while rotating with the transport cylinder 3, are provided. The scraping finger 4 is provided diagonally with respect to the rotation axis of the collecting cylinder 3 and across the width of the transport port 2. Further, the scraping finger 4 is the same as the stalk feeding direction of one spiral 8 with respect to the transport port 2. The finger rows (a) and (a) arranged so as to be out of phase so as to be in the feeding direction, and the transfer port 2
On the other hand, the harvesting of the combine is characterized in that finger rows (b) and (b) arranged so as to be shifted in phase are respectively provided so as to have the same feeding direction as the stalk feeding direction of the other spiral 8. It is a grain culm collection and delivery device.

[Function and effect of device]

During combine operation, the grain stalks cut by the cutting blade device 1 are
By the rotation of the collecting tube 3 on the rear side, the collected collecting stems 4 are collected from both left and right sides, and the collected stems are further engaged by the collecting finger 4 and conveyed on the rear side. Mouth 2
It is scraped into and transported to the rear threshing device section.

The scraping action of the scraping fingers 4 is such that each scraping finger 4 is displaced in the axial direction in accordance with the rotation of the collecting tube 3 so as to extend over the width of the transport port 2 while engaging the stems. The scraping fingers 4 are combined and scraped toward the transport port 2 side.
The interval of engaging action of the stems by the stalks is made close, and moreover, the transport port 2
In order to squeeze the entire width of the stalk, the stalks of the culm can be thinly averaged, and by using the finger rows out of phase, they also have the function of laterally feeding inward. Therefore, the collection and delivery effect is enhanced, and the transport port 2
It can be smoothly fed into and can be less clogged. In addition, the protruding length of each of the scraping fingers 4 can be shortened to ensure smooth scraping.

〔Example〕

In the illustrated example, the mowing device has a clipper-shaped mowing blade device 1 at the lower end of the front part, and a collecting and receiving plate 5 is provided on the rear side of the cutting and collecting device, and the axis of the collecting and receiving plate 5 is arranged along the lateral width of the collecting and receiving plate 5. The configuration is such that the collecting and feeding tube 3 along the side is rotationally transmitted. On the rear side of the collecting and receiving plate 5, the conveying port 2 is provided at the center in the lateral width direction or at a position near the left and right 1 sides.
Is provided, and a conveyor 7 that conveys the grain culm scraped into the transport port 2 to the threshing device 6 at the upper rear is provided.

On the outer peripheral surface of the collecting tube 3, there is provided a spiral 8 for collecting the stems from both left and right ends toward the transfer port 2, and a spiral is not formed in a portion facing the width of the transfer port 2. The scraping finger 4 is provided. The scraping finger 4 is inserted into and retracted from a finger hole 9 provided in the collecting cylinder 3, and a base end portion thereof is rotatable with respect to an eccentric shaft 10 provided at a fixed position along the collecting cylinder 3. Pivotally support the tip end of the eccentric shaft 10 by causing the tip end portion to project outward from the finger hole 9 and rotating the collecting cylinder 3 to rotate each scraping finger 4 in the same direction by fitting in the finger hole 9. On the eccentric side, that is, on the front side,
It is set to have a relationship in which it projects from the peripheral surface of the sheet and becomes shorter on the side of the conveying port 2 on the rear side, or retracts from the surface of the collecting cylinder 3.

Moreover, each of these finger holes 9 and the scraping finger 4
Is a constant rotation phase angle across the width of the transport port 2,
Moreover, they are sequentially shifted in the axial direction and arranged on a line inclined with respect to the axial direction. The inclined line on which the scraping fingers 4 can be arranged has a zigzag shape. That is, a plurality of phase-shifted feed directions, which are on the right side with respect to the combine traveling direction of the transport port 2 and are in the same feeding direction as the stalk-feeding direction (direction of the transport port 2) of the spiral 8 provided on the circumferential surface of the collecting cylinder 3. Swipe finger 4
The row (a) is arranged, and further, the feed is the same as the stem-culm feeding direction (direction of the feeding port 2) of the spiral 8 provided on the circumferential surface of the collecting tube 3 on the left side with respect to the direction of movement of the combine of the feeding port 2. In the direction
4 rows (b) of a plurality of scraping fingers whose phases are shifted are arranged. The feed direction of the stems is a right-to-left direction with respect to the moving direction of the combine, or a left-to-right direction with respect to the moving direction of the combine. (A), (b)
Are alternately provided on the peripheral surface of the collecting cylinder 3. As a result, the stems are subjected to the action of being alternately fed from the right side to the left side and from the left side to the right side with respect to the combine traveling direction on the peripheral surface of the collecting cylinder 3 facing the conveying port 2. Is increased and is taken into the rear conveyor 7 without fear of jamming.
