Description

[Detailed description of the invention] The present invention relates to a husk conveying device in a combine harvester. Specifically, the foot chain starting end of the threshing device is protruded from the upper side of the conveyor, and the husk culm is conveyed on the upper surface of the foot chain. The terminal end portion of the conveying body configured to convey and supply the plant, which pinches and conveys the stem portion of the culm harvested from the reaping portion provided at the front lower part of the machine body, is positioned so as to be able to be inherited near the starting end portion of the foot chain; A pinning guide rod and an auxiliary pinning guide located between the terminal end of the transport body and the starting end of the foot chain, the base end of which is pivotally attached to the transport body side, and the other end as a road end, located near the transporting surface of the starting end of the foot chain. are arranged in vertical positions at least near the upper surface of the starting end of the foot chain, and the lower auxiliary pinning guide is arranged to be located on the upper side of the conveyance with respect to the upper pinning guide, and As a conventional technique, a single guide rod was installed at the joint between the conveyor and the foot chain, and the guide rod supplemented the joint space up to the foot chain's foot chain in the 4th century of the U.S.
As seen in Japanese Patent No. 7-2826, since there is only one clamping guide rod, a situation may occur in which clamping is not possible depending on the number of conveyor culms.

That is, when a multi-layered shell culm is located at the tip of the trapping rod, the trapping rod is pushed upward, and a space is formed between the base and the foot chain.

Therefore, in view of these drawbacks, the present invention has the following features:
Consists of a pinning guide rod and an auxiliary pinning guide, and since it is close to the transfer position, there is a high possibility that the shell culm will fall off. It is placed below the pinning guide rod to support the shell culm, which is transferred from the conveyor to the foot chain of the threshing device, so that it can be transported reliably and smoothly regardless of the amount of conveyance. This is to prevent the culm from falling off.

The present invention will be described in detail with reference to embodiment figures.

FIG. 1 shows a side view of the combine harvester, in which a shell culm transfer device consisting of a foot chain 5 and a culm 8 projecting to one side is installed at the front of the threshing device 4 mounted on the top of the traveling device 7. A supply port 9 is provided on one side of the threshing device 4 and a fourth port is provided on the other side, a cutter 10 is installed behind the threshing device 4, and a reaping and conveying section 5 is installed in the front part of the machine body to be connected to the threshing device 4. Set up

In the reaping and conveying section, the cutting body 11 and the culm lifting device 12 are equipped at the frontmost part, and the roots of the culms are moved from above the reaping section 1 provided at the rear lower part toward the supply port 9 side of the threshing device 4. A lower conveying body 3 for pinching and conveying the sides is installed obliquely, and above it, an upper conveying body 2 and a clamping rod 2' for pinching and conveying the tip side of the culm are installed obliquely and extending toward the front of the supply port 9.

Further, above the upper end of the lower carrier 3, an auxiliary carrier 3' is provided which connects and feeds the root side of the culm to the foot chain 5, and is fixed to the fuselage via a support pipe 13. A clamping rod 15 facing the auxiliary conveyor 3' is attached to the support 14, and a gripping guide rod 16 with one end fixed to the support 14 projects from the front of the auxiliary conveyor 3' toward the front side of the supply port 9. The foot chain 5 is extended to the front of the clamping culm 8, and a bolt 1 is attached to the top of the support 14.
Auxiliary gripping guide 6 having elasticity made of a longer wide plate than 7
With one end fixed, the auxiliary gripping guide 6 is attached to the gripping guide rod 1.
6 and extend the foot chain 5 at the protruding tip.
It extends from above the part along its length to a certain distance so as to come into contact with the chain pin 5', and its tip 6' is turned into a free end, and the root side of the culm is pressed from above by the auxiliary gripping guide 6. It is configured such that the image is transmitted in contact with the protruding tip of the foot chain 5.

In this case, the gripping guide rod 16 and the auxiliary gripping guide rod 6 are arranged in two stages, upper and lower, and the latter is located on the upper side of the transport side than the former.

The culms cut by the reaping section 1 during the combine harvesting operation are conveyed by the lower conveyor 3 on the root side and by the upper conveyor 2 and the holding rod 2' on the tip side, and are transferred to the threshing device 4 side. .

At the point where the base side is transferred from the lower conveyance body 3 to the auxiliary conveyance body 3' and further conveyed by the clamping rod 15 while changing direction, the base side is transferred to the foot chain 5 while being clamped and guided by the clamping guide rod 16. so as to relate to
Furthermore, the feed is carried out so as to be pinched and transferred between the foot chain 5 and the gripping rod 8, but in this state, the root side of the culm is first placed in the auxiliary gripping guide located below on the starting end of the foot chain 5. The rod 6 strongly presses and guides the upper surface of the foot chain 5 with its wide surface, and then it is securely held and conveyed by the gripping guide rod 16, and at the same time, the tip side is placed on the tip side of the upper conveyor 2. and is supplied to the supply port 9.

In this way, the present invention is configured such that the starting end of the foot chain 5 of the threshing device 4 is protruded from the upper side of the conveyor so that the husk is conveyed and supplied on the upper surface of the foot chain 5, and the reaping section is provided at the front lower part of the machine body. The terminal end of the conveying body 3 which pinches and conveys the stump base of the culm cut from 1 is located near the starting end of the foot chain 5 so as to be able to take over the terminal end of the conveying body 3 and the starting end of the foot chain 5. Between the sections, at least a gripping guide rod 16 and an auxiliary gripping guide 6 are located near the conveying surface of the starting end of the foot chain 5, with the base end pivoted to the conveying body 3 side and the other end being a free end. A lower auxiliary grip guide body 6 located in a vertical position near the upper surface of the starting end of the feed chain.
Since it is arranged so as to be located on the upper side of conveyance with respect to the upper gripping guide body 16, the following remarkable effects can be achieved.

That is, at the transfer point where the culm is conveyed from the conveyor to the foot chain of the threshing device, the gripping guide rod and the auxiliary gripping guide rod provided behind the foot chain from the conveyor side to the foot chain starting end are at least near the upper surface of the foot chain starting end. By positioning the lower guide body on the upper side of the conveyor with respect to the upper guide body, the culm group that is successively transferred to and from the foot chain start end is transferred to the foot chain start end. Under the action of both the upper and lower guide rods on the section, the inherited culm is firstly firmly supported by the lower guide rod, and as the foot chain moves, it is pushed side by side in layers, and then the upper and lower The culm is held and conveyed by the guide rod on the lower side of the conveyor, making the transfer of the culm extremely smooth and reliable.If there is a large amount of culm, the culm is transferred by the auxiliary grip guide on the lower side as described above. It securely supports the shell culm, and evens out the shell culm by moving the foot chain to form a layer, and even in the case of small quantities, the guide rod on the upper side acts to transport the shell culm without falling off. be able to.
