Description

[Detailed description of the invention] The present invention has a stem culm raking wheel that is mounted on the front side of a horizontal conveyance device that conveys the reaped stem culm in the horizontal direction, and that scrapes and transfers the stem culm to the side of the horizontal conveyance device by relative rotation. The present invention relates to a reaping and conveying device which is provided with a pair of bodies.

Since this type of reaping and conveying device uses a rotating culm scraping wheel as a scraping and transferring device, the overall structure, including the power transmission device, is simpler than when using an endless conveying chain with locking claws. It also has the advantage of being lightweight, easy to construct at low cost, and easy to handle without requiring complicated adjustment work such as chain tension adjustment. Since the stem culm scraping wheel located on the upper side of the conveyance device rotates in the opposite direction to the conveyance direction of the horizontal conveyance device at the meeting point with the horizontal conveyance device, the stem culm scraping wheel located on the upper side of the conveyance device rotates in the opposite direction to the conveyance direction of the horizontal conveyance device. The reaped stem culm being removed is prevented from being conveyed by the rear end of the stem culm scraping wheel on the upper side of conveyance,
Alternatively, it may be thrown off in front of the cutting blade by the culm scraping wheel, which has the drawback of causing a problem in the intended conveying action of the reaped culm by the horizontal conveyance device.

Therefore, among the pair of stem culm raking wheels, the raking claws of the stem culm raking wheel located on the upper side of transport of the horizontal conveyance device are moved to the stem culm raking transfer path toward the horizontal conveyance device side. It is conceivable to configure it into a so-called magic finger type in which it protrudes upright on the side and can be retracted in a sword-like manner toward the axis of the stem culm rake wheel on the side of the stem culm lateral conveyance path by the horizontal conveyance device. In this case, the stem culm rake ring structure becomes complicated, and the structural advantages of not using an endless chain cannot be expected.

In view of the above-mentioned circumstances, the present invention provides the structural advantages of using the rotating culm scraping wheel as described above, while ensuring that the desired reaped culm conveying action is achieved by the horizontal conveying device. This is designed to be able to perform the cutting process smoothly and well. The culm raking wheels are arranged so that their front ends are located in the same or almost the same plane in the direction of movement of the machine, and the culm raking wheel on the smaller diameter side is located on the upper side of the transport of the lateral transport device. It is characterized by this.

That is, the reaping and conveying device according to the present invention has both stalk culm scraping wheels configured with different diameters, the front ends of which are located in the same plane in the direction of movement of the machine, and the stalk culm scraping wheels on the smaller diameter side. By arranging the pruning wheel so as to be located on the upper side of the conveyance side of the lateral conveyance device, a sufficient distance can be created between the locus of action of the stalk culling wheel on the small diameter side and the locus of conveyance action of the lateral conveyance device. This prevents the reaped stem culm being conveyed by the horizontal conveyance device from being blocked by the stem culm scraping wheel on the upper side of conveyance, or from being thrown off in front of the cutting blade. Therefore, the intended function of conveying the cut stems and culms by the horizontal conveying device can be reliably and satisfactorily performed.

Therefore, the present invention utilizes a rotating stem culm raking wheel and an extremely simple improvement in which the pair of stem culm raking wheels are configured to have different diameters. While taking advantage of the structural advantages of the present invention, it has now become possible to reliably and satisfactorily perform the desired function of conveying the cut stems and culms by the horizontal conveying device.

Embodiments of the present invention will be described in detail below based on the drawings.

Figure 1 shows a combine harvester, with a clipper type reaping device 5.
And, near the ground in front of this reaping device 5, four rows of planted culms (

A horizontal conveying device 1 consisting of a vertical conveying device section 1B that continuously conveys the cut culm to the rear of the machine body, and a horizontal conveying device section 1B of the horizontal conveying device 1 that scrapes and transfers the culm by relative rotation. A reaping section I is provided, which is composed of a reaping and conveying device 4 in which two pairs of stem culm raking wheels 2 and 2' are arranged side by side at an appropriate interval in the left and right lateral directions, and this reaping section 7 and the threshing section 8 mounted on the rear part of the machine, the vertical conveying device section IB of the horizontal conveying device 1
A stock clamping and conveying device 9 that clamps the stock part of the harvested husk culm being conveyed by M and transports it to the feed chain 8A of the threshing section 8, and a stock part holding and conveying device 9 that locks the tip part of the reaped husk culm. A tip retaining conveyor 10 is installed to convey the grain to the culm supply port 8a of the threshing section 8 in a state in which the grain is turned sideways in cooperation with the stock head clamping and conveying device 9.

As shown in FIG. 2, the reaping and conveying device 4 has the pair of stem culm raking wheels 2 and 2' and 2 and 2' having different diameters. 2゜2' and 2,2'
, the front ends of which are located in the same or almost the same plane in the direction of movement of the machine, and the culm scraping wheels 2 and 2 on the small diameter side are transported by one person in the lateral transport device section of the lateral transport device 1.
