Description

[Detailed description of the invention] The present invention provides a drum-shaped rotating body with a plurality of pawl through holes arranged in the circumferential direction and a working opening closed with a removable lid. On the other hand, a plurality of stem culm transfer claws that rotate integrally around an axis substantially parallel to the rotation axis are individually protruded from the claw through holes, and the transfer claws rotate as the drum-shaped rotating body rotates. The present invention relates to a rotary body for transporting stem culms, which is adapted to rake in reaped stem culms in, for example, a reaping harvester, etc., by a rotational action and an egress/retraction action due to misalignment of the axis of rotation.

Conventionally, in the rotary body for transferring stem culms, the pawl through holes were distributed only on the peripheral wall of the drum-shaped rotary body, which had an integral structure. During assembly, it is not possible to insert the pawls from the inside of the rotating body, and therefore, as shown in FIG. Crank rotating shaft 16 assembled into body 10
, the worker removes the rotating body 1 from the working opening 21.
However, it is extremely troublesome work to assemble and connect each of the many transfer claws 18 inside the rotating body 10, which has a narrow working space. However, there was a problem that the assembly efficiency was greatly reduced.

In view of the above-mentioned circumstances, an object of the present invention is to provide a rational and extremely simple improvement to the lid of the working opening, thereby greatly facilitating the assembly of the transfer claw.

The characteristic configuration of the present invention is that in the above-mentioned rotary body for transporting stems and culms, a part of the claw through hole is formed in the lid, and the functions and effects thereof are as follows.

In other words, with an extremely simple modification of just forming a part of the claw through hole in the lid of the working opening,
As shown in FIG.
As the is assembled into the rotating body 10, all the claws 18 other than the claws 18 that are inserted into the through holes 23 of the lid 22 are inserted from inside the rotating body 10, and the lid 22 is
By assembling the remaining claws 18 into the rotating body 10 while inserting them into the through holes 23 formed therein, the assembly of all the claws 18 can be completed. Inside, one of the many pawls 18 is connected to the crankshaft 16.
The assembly of the pawl 18 can be made much easier than when the pawl 18 is connected to
It has now been possible to dramatically improve the manufacturing efficiency of the rotating body for transporting stem culms.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

As shown in FIG. 1, a machine frame 2 equipped with a pair of left and right crawler-type traveling devices 1 is provided with an automatic threshing device 3 and a boarding operation section 4, as well as a rotary reel 5 for scraping the planted grain culm, A reaping device 6 reaps the raked grain culms, gathers the harvested grain culms near the left and right center of the machine, and scrapes the gathered grain culms to the conveyance start end of the threshing device supply conveyor 7. A reaping section 9 equipped with various devices such as a rotating body 8 for transporting grain culms for feeding and supplying the grain is provided at the front end of the machine body so as to be able to be raised and lowered, thereby forming a combine harvester.

As shown in FIGS. 2 to 5, the rotary body 8 for transferring grain culms is constructed by a driving rotary shaft that is arranged concentrically with a drum 10 as the main body of the rotary body 8 at one end thereof. 11, and is relatively rotatably supported via a bearing 13 on a fixed rotating support shaft 12, which is also arranged concentrically on the other end side, Spiral augers 14 are respectively attached to the outer periphery of the outer portions, and the rotation of the augers 14 accompanying the drive rotation of the drum 10 moves the harvested grain culm toward the center in the longitudinal direction of the drum 10, that is. , and is configured to be transported horizontally toward a location corresponding to the transport start end of the conveyor 7.

In the figure, reference numeral 15 denotes a chain sprocket on the rotating shaft side in a chain interlocking mechanism that transmits driving force to the rotating shaft 11.

One crankshaft 16 is eccentrically arranged parallel to the drum rotation axis P inside a portion of the drum 10 in the longitudinal direction that corresponds to the width of the conveyor 7. One end is connected to the drive rotation shaft 11 via a bearing 17 so as to be relatively rotatable, and the other end is integrally connected to the rotation support shaft 12.

Then, a total of nine grain culm transfer claws are arranged at equal pitches in the longitudinal direction of the drum, with the rotational phases being different by 120 degrees when viewed in the direction of the drum rotation axis P, and with the same rotational phase being arranged at equal pitches in the longitudinal direction of the drum. 18 are pivotally connected to the crankshaft 16 while penetrating the peripheral wall of the drum 10 so as to be freely retractable. Each pawl 1 with 10 rotations
8 are rotated around a crankshaft 16 while being moved in and out sequentially, and the harvested grain culms collected by the auger 14 are supplied and transferred to the conveyance starting end of the conveyor 7 by the scraping action of the claws 18. .

To configure the assembly structure of the grain culm transfer claw 18, the crankshaft 16 is connected to the rotation shaft 11 and the rotation support shaft 1.
A pair of left and right crank arms 19 connected to 2,
Crankshaft connection part 19a and drum shaft connection part 19b
At the same time, both connecting portions 19 are formed separately.
a and 19b are integrally connected by bolts 20.

The claw 18 is provided in the longitudinal direction of the drum 10.
The working opening 21 covering the entire width of the drum 1
0 in the circumferential direction, and a lid 22 for the working opening 21 is attached to the drum 10 by bolts 22a.
The through hole 23 forming member 24 allows the pawl 18 to penetrate through the drum peripheral wall so as to allow the pawl 18 to move in and out and to swing slightly due to eccentric rotation. Of the three rotational phases of every 120°, those for two rotational phases are attached directly to the peripheral wall of the drum, and the one for the other rotational phase is attached to the lid 22 of the working opening 21.

That is, when assembling the pawl 18 to the drum 10, as shown in FIG. In this state, the through-hole forming member 2 has six claws 18 corresponding to two rotational phases attached to the drum peripheral wall.
The crankshaft 16 is inserted into the drum 10 from the working opening 21 while penetrating each of the drum shafts 16 from the inside of the drum 10, and the crankshaft connecting portion 19a is attached to the drum shaft connecting portion 19b previously attached to the drum side shafts 11 and 12.
Connect them with bolts 20 and assemble the crankshaft 16.

Then, when closing the working opening 21, the lid 22 is attached to the drum 10 while passing each of the three claws 18 corresponding to the remaining phases through the through-hole forming member 24 attached to the lid 22. , compared to the conventional structure shown in FIG. 7, in which each of the many pawls 18 is inserted from the outside of the drum 10 and assembled to the crankshaft 16 inside the drum 10, the assembling of the pawls 18 is greatly simplified. It is structured so that it can be performed easily and efficiently.

The number of stem culm transfer claws 18 arranged in the circumferential direction of the drum 10 and the number arranged in the longitudinal direction of the drum can be changed as appropriate. The number of pawl through holes 23 arranged in the circumferential direction of the drum, and
The number of the drums arranged in the longitudinal direction of the drum can also be changed as appropriate.

Also, the specific assembly structure of the crankshaft 16 into the drum 10, and the structure of the crankshaft 16 of each pawl 18.
Various improvements can be made to the specific pivot connection structure for the claws, and various improvements can also be made to the specific structure of the pawl through holes 23.

The present invention is directed to a rotary body for transferring stem culms provided in various types of stem culm conveying devices such as the reaping section of a combine harvester.
