Description

[Detailed description of the invention] The present invention mainly relates to a waste straw bundling processing device installed in a harvester, and more specifically, it includes a device for pinching and conveying bundled waste straw, and a device located below the terminal end of the device for pinching and conveying bundled waste straw. A mechanism for holding the previously supplied bundled waste straw is placed between the packer and the packer that collects and supplies the bundled waste straw into the convergence space of the device that binds a plurality of pieces of bundled waste straw, and the next bundled waste straw is placed in the clamping and conveying device. In order to switch to the holding release state as it moves to the terminal end,
This relates to devices that are automatically switched.

The above-mentioned waste straw bundling processing device allows all of the bundled waste straw to be discharged from the clamping and conveying device even if the bundled and discharging straw is conveyed in a state where it is spread out in the conveying direction by the pinching and conveying device. By supplying the bundled waste straw to the packer in a state where it is held in place, it is possible to avoid the trouble of the packer acting on the bundled waste straw while a part of the bundled waste straw is being clamped. By the way, in the past, the patent application
As proposed in No. 145199, the held waste straw is simply fed to the pack car in a state of falling under its own weight, but in this case, the movement of the held and bundled waste straw to the pack car side is connected to the next bundled waste straw. There was an inconvenience in that it was difficult to reliably supply to the police car due to the obstruction caused by the entanglement, and there was room for improvement.

More specifically, it is necessary to confirm that all of the previously supplied bundled waste straw has been discharged from the clamping and conveying device when the next bundled and discharging straw reaches the end of the clamping and conveying device. There is a risk that the preceding bundled waste straw and the following bundled waste straw may become entangled as they approach each other, and the entanglement becomes more pronounced as the bundles of bundled waste straw become larger. It was difficult to release the bundled waste straw and properly supply it to the police car.

For this reason, the present inventor proposed a reciprocating swing-type conveying device that locks and conveys the holding waste straw to the pack car side when the holding mechanism is released from holding, and a clamping frame that is arranged opposite to the feed chain in the clamping and conveying device. For this purpose, we proposed a means of interlocking and connecting via a link mechanism so that it can swing back and forth as it moves, but in this configuration, the overall structure is complicated due to the need for a link mechanism. Not only that, but also the amount of movement of the clamping frame fluctuates depending on the size of the bundled waste straw, which makes it difficult to always operate the conveying tool accurately with the desired stroke, which leaves room for improvement. .

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to eliminate bundled straw by simple modification, regardless of entanglement, and regardless of fluctuations in the size of bundled waste straw. The purpose of this system is to enable the accurate supply of straw to the patrol cars.

A characteristic configuration of the waste straw bundling processing device according to the present invention is such that when the holding mechanism is in the release state, a rotating body with a locking protrusion that locks and conveys the held waste straw to the packer is conveyed by the clamping and conveying device. It is provided so that it can be pressed and rotated by the following bundled and discharged straw.

Next, the effects of the feature configuration of the present invention will be described.

That is, as the holding mechanism is switched to the holding release state, the holding and discharging straws are held and conveyed to the packer by the rotating body, so that even if the held bundled and discarded straw becomes entangled with the following bundled and discarded straw, However, regardless of the entanglement, the retained waste straw can be separated from the subsequent bundled waste straw and reliably supplied to the pack car. In order to drive the rotary body, the structure for driving the rotary body can be simplified, and the structure for driving the rotary body can be simplified by pressing and rotating it by the subsequent bundled waste straw that is being held and conveyed. The rotating body can be accurately rotated as specified regardless of variations in the size of the straw.

Therefore, all of the bundled waste straw can be discharged from the clamping and conveying device and can be supplied to the car without getting entangled with the following bundled waste straw, and the effect for this can be adjusted to the size of the bundled waste straw. In addition, the structure can be simplified, and as a result, a waste straw tying device that can be used even better has been obtained.

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

FIG. 1 shows a waste straw tying device in which a tying device 2 is provided opposite the waste straw outlet of a threshing device 1 mounted on a harvester, and a plurality of clamping frames 4 are installed along the lower part of a feed chain 3. The pin is pivotally supported for bending and swinging, and the clamping frame is pivotably connected.
A spring 5 is provided to press each end of the clamping frame 4 on the final conveying end side toward the chain, and the bundled grain culms that are sequentially supplied manually are clamped and conveyed for threshing, and the bound grain culms are bundled after the threshing process. Threshing device for waste straw 1
A packer 7 is provided below the terminal end of the clamping and conveying device 6 to scrape and supply bundled waste straw to the convergence space B of the binding device 2. , and is configured to bundle and release a plurality of bundled waste straw after threshing.

To configure the binding device 2, a string supply needle 8 is provided below the focusing space B, and a knot building 9, a string holder 10, and a release arm 11 are provided above the focusing space B. A focusing pressure sensing door 12 is provided at the exit of the focusing space B, and is configured to perform a binding operation every time the door 12 senses a set focusing pressure.

As shown in FIGS. 1 and 2, a guide rod 13 extends downward from the rear end of the feed chain 3 in a fixedly supported manner, and cooperates with the guide rod 13 to When the next bundled waste straw is moved to the terminal end of the clamping and conveying device 6, the receiving rod 14 that holds the bundled waste straw supplied to the terminal is moved to the downward holding release position, and at other times to the upper holding action position. In order to automatically change the position so as to maintain the position of the clamping frame 4, the clamping frame 4 is attached to the terminal end 4 of the plurality of clamping frames 4 so as to move up and down integrally. In order to be able to hold the previously supplied waste straw, and to supply the held bundled waste straw to the packer 7 as the next bundled waste straw moves to the terminal end of the clamping and conveying device 6. It is configured to release the hold.

A locking protrusion 15 that locks and conveys the holding waste straw to the pack car 7 when the holding rod 14 is released from holding.
The attached plate-shaped rotating body 16 is externally fitted onto the support shaft 17 with one of the locking protrusions 15 protruding into the conveying action location on the terminal end side of the clamping and conveying device 6, and the rotating body 1
The rotational position holding roller 18 of 6 is connected to the spring 19.
The holding bundled waste straw can be supplied to the packing car 7 by pressing and rotating the rotating body 16 by the subsequent bundled waste straw being conveyed in a pinched manner. It is structured as follows.

To carry out the present invention, as described in the embodiment, if the bundled waste straw is held in a weakly held state between the receiving rod 14 and the guide rod 13, the bundled waste straw that is pushed out in the conveying direction can be removed. In cooperation with the extrusion action of the feed chain 3, the straw can be returned to a nearly circular state.

This invention can be used by equipping a harvester, as well as
It can be used in various forms, such as in a combine harvester equipped with a harvested grain culm binding device at the front of the threshing device.

In addition, in configuring the holding mechanism, in addition to providing the receiving rod 14, various configurations can be changed, and the holding mechanism 1
4, various changes can be made, such as operating the switching actuator based on information from the bundled waste straw detection sensor.

Furthermore, instead of the plate-like rotating body 16 with the locking projections 15, an endless band with locking projections can be used.
These are collectively referred to as a rotating body with locking protrusions.
