Description

[Detailed Description of the Invention] The present invention relates to a planted shell culm lifting device used for agricultural combine harvesters, binders, etc., which is small and operates quietly;
The purpose is to have excellent fire resistance.

Among the planted culm lifting devices, there are types shown in FIGS. 2 to 5.

In other words, its basic structure is that as the drive band rotates vertically within the case, it is pivoted at appropriate intervals in the direction of rotation of the drive band so that it can freely rotate approximately parallel to the rotational surface of the drive band. The planted shell culm lifting claw is configured to be maintained in the planted shell culm lifting position in which it protrudes outside the case by a cam plate only during the rising process.

Of these, FIGS. 4 and 5 each show a conventional example.

In the case shown in FIG. 4, the upper wall portion 14 and the descending side wall portion of the case 8 are shaped such that the tip end 12 of the raising pawl 10 protrudes outwardly from the rotation locus 22 that protrudes maximum from the drive band 9. 17 is formed.

For this reason, the case 8 becomes large in size, takes up space, and is expensive.

In the case shown in FIG.
An upper wall portion 14 and a lower side wall portion 17 are formed,
A rubber plate 24 is pasted across both wall portions 14 and 17 to cushion the protrusion of the lifting claw.

For this reason, an extra rubber plate 24 is required, and the lifting claw 10
The rubber plate 24 strongly collides with the rubber plate 24, causing early damage, and the collision noise is louder and noisier.

The present invention aims to eliminate the above-mentioned drawbacks.

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

The drawing shows a two-row agricultural riding combine harvester, which, as the machine moves forward, divides the culms to be planted in the field with the weeding tool 1, pulls them up with the pulling device 2, reaps them with the reaping device 3, and The paddy is sent to the rear by a feeding device 4, sent to a threshing device 5 for threshing, the waste straw is discharged to the rear side of the machine, and the threshed paddy is put into a paddy bag 7 from a paddy removal tube 6. ing.

Figures 2 and 3 show two sets of planted culm lifting devices 2 lined up on the left and right, the basic structure of which is as described above, and is characterized in that the left and right cases are constructed as follows. do.

That is, the upper wall portion 14 of the case 8 is formed in a shape that projects slightly outward from the movement locus 13 of the portion where the tip portion 12 of the lifting claw 10 reverses from rising to falling.

An outer wall portion 17 of the case 8 is formed along the outer side of the lowering portion of the lifting claw 10 (D protrusion 15 formed at the base end) near the movement trajectory 16.

The case 8 is formed by overlapping a back plate 8a and a front plate 8b and fastening them with bolts.

The back plates ±8a-8a and the front plates ±8b-8b of the two left and right pairs of cases 8 are formed in series so as to be connected at the upper connecting plate portion 18, respectively.

Among them, 19 is a driving wheel, 20 is an idler wheel, and 21 is a pawl pivot pin.

The driving band 9 is composed of a chino. Since the present invention is configured as described above, it has the following effects.

In other words, even if the trigger claw is swung outward with great force when reversing from rising to descending, it will simply swing in vain and will not collide with the upper wall of the case, making it possible to drive quietly without making a collision noise. , the lifting claws are not damaged and have excellent durability.

Furthermore, the structure is simplified since no cushioning rubber is required.

Furthermore, since the outer wall portion of the case is inward from the locus of movement where the tip of the lifting claw protrudes to the maximum and descends, the case can be made smaller accordingly, taking up less space and being cheaper to manufacture.

Claims (1)

[Scope of utility model registration request] The drive band 9 is mounted between the drive wheel 19 placed at the top of the case B and the idler wheel 20 placed at the bottom, and as the drive band 9 rotates in the vertical direction inside the case 8, Planted culm lifting pawls 10, which are rotatably supported approximately parallel to the rotational surface of the drive band 9 at appropriate intervals in the rotational direction of the drive band 9, protrude outside the case by a cam plate 11 only during the rising process. In the planted shell culm lifting device configured to maintain the planted shell culm in a raised posture, the tip portion 12 of the lifting claw 10 moves due to inertia at the portion where the lifting claw 10 reverses from rising to descending. The upper wall portion 14 of the case 8 is formed in a shape that protrudes outward from the trajectory 13, and is formed in a shape along the outer side near the movement trajectory 16 of the descending portion of the lifting posture holding protrusion 15 formed on the lifting claw 10. A device for raising a planted shell culm, characterized in that an outer wall portion 17 of a case 8 is formed.
