Description

[Detailed description of the invention] The present invention is designed to install a threshing straw at the end of the threshing feed chain in order to shred the threshed waste straw from the feed chain or transport it to a dropper or the like to process it in a long straw state. In addition to providing a cylinder type cutter to shred the
Regarding the threshing machine equipped with a horizontally rotating type straw clamping and conveying device that is connected to the feed chain and conveys waste straw in a direction perpendicular to the conveyance direction, the cylinder The purpose is to ensure that waste straw can be supplied to the mold cutter in a good manner.

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

A cylindrical cutter 3 is provided at the end of a feed chain 2 that pinches and conveys the harvested husk to the handling chamber 1 for threshing, and a discharging straw pinching and conveying device 4 and a dropper are connected to the feed chain 2. 5,
The clamping rail 6 of the conveying device 4 is movable and fixed between a clamping position for the waste straw and a non-clamping position located below the clamping position, and as the position is changed, the cutter 3 and the dropper The structure is configured to selectively supply waste straw to the reaped straw 5, and thus constitutes a combine harvester that is mounted on a traveling vehicle body equipped with a crawler traveling device 7 and harvests and processes planted husk culms in a field. A threshing device is installed to thresh and sort the culms and to discharge the waste straw into the field in pieces or intermittently in predetermined amounts as long straw.

The waste straw holding and conveying device 4 is constructed in a horizontally rotating type with its conveying surface facing vertically, and is provided with the conveying direction perpendicular to the conveying direction of the feed chain 2. Due to the action of the guide rod 8 which receives the tip side of the coming waste straw and guides the transfer to the upper side of the conveying device 4, and the curved structure of the tip end portion 6a of the clamping rail 6, the waste straw in the above-mentioned receiving posture is By cooperating with the downward pressing action on the middle, the holding and conveying device 4 is configured to feed the material to the delivery dropper 5 in an upright position.

The clamping rail 6 has its tip end portion 6a rotatable and fixed relative to the conveyance terminal end portion 6b, and is movable between a clamping position and a non-clamping position located below the clamping position. , and in the non-clamping state, the tip is positioned below the conveying action level of the feed chain 2 to receive the straw conveyed and discharged by the feed chain 2, and the above-mentioned in the non-clamping conveyed state is placed in the middle of the discharged straw. The rotating band 9 with projections of the conveying device 4 is provided with an auxiliary conveyance function, and the waste straw that has come off the feed chain 2 is conveyed to the cutter 3 through the cooperation of the above-mentioned auxiliary conveyance function and the receiving and guiding function of the clamping rail 6. This is how it is structured.

In the above embodiment, three sprockets 10...
The clamping and conveying device 4 is constructed in such a way that a rotating band 9 with protrusions is wound around the feed chain 2 to form a relatively long conveying path, as shown in FIGS. 5 and 6. This method is applied to a device in which the rotating band 9 is wound around two sprockets 11a and 11b, and an auxiliary conveying action is applied to the non-clamped waste straw at the rotating portion of the sprocket 11a on the feed chain 2 side. You may configure it as much as possible.

In the present invention, instead of the dropper 5, various waste straw processing devices such as a bundling device may be provided, or the straw may be dropped as long as it is.

In summary, the present invention provides a threshing device that includes:
The clamping rail 6 of the waste straw clamping and conveying device 4 is configured to be freely movable between a clamping position and a non-clamping position located below the clamping position, and in the non-clamping state of the clamping rail 6, The waste straw conveyed by the feed chain 2 is assisted by the rotating band 9 with protrusions of the waste straw holding and conveying device 4, and the waste straw that has come off from the feed chain 2 is transferred to the rotation with the protrusions. It is characterized in that it is configured to be conveyed toward the cutter 3 by the cooperation of the conveying action of the movable band 9 and the receiving and guiding action of the clamping rail 6.

In other words, switching between supplying waste straw to the cutter 3 and delivering it to the waste straw holding and conveying device 4 is not only done by changing the operating position of the clamping rail 6, but also by effectively utilizing the switching configuration. When the waste straw is being fed to the cutter 3, the pinch rail 6 catches and guides the waste straw that has come off the feed chain 2, while the protruding rotary band 9 imparts a conveying action to the waste straw. Therefore, it has become possible to reliably supply waste straw to the cutter 3 with a simple improvement of rationally setting the non-clamping action position of the clamping rail 6 without providing a special device.
