Description

Detailed Description of the Invention [Field of Industrial Application] The present invention provides a convergence section for stem culms in a horizontally suspended posture, and a forced transfer path to the convergence section by upper and lower first guides, and A sensing door that senses the pressing force of the stem culms and opens to discharge the bundled stem culms when the sensed pressure exceeds a setting is provided so as to be retracted to the lower first guide side, and the forced transfer path The present invention relates to a stem and culm binding device in which the first guide is bent so that the vertical width of the convergence portion is larger than that of the first guide.

[Conventional technology]

In the above-mentioned stem culm binding device, in order to collect the stem culms sent from the forced transfer path in an appropriately dense state without causing any looseness, the vertical width of the converging section is formed to be approximately the same width as the vertical width of the transfer path. However, due to the forced feeding function of the stem culm, there is a restriction on the vertical width of the transfer path, so the vertical width of the converging section is also restricted.

However, under these constraints, if you try to increase the amount of tied stem culms per batch and perform so-called large bundle binding in order to improve the stem culm processing capacity and tied stem culm collection efficiency, it is difficult to The culms must be formed to be long in the transport direction, which causes problems such as the shape of the bundle becoming flat and the binding string becoming loose, causing the bundled stem culms to come apart and making it more difficult to collect. It was hot.

Therefore, conventionally, as shown in Japanese Utility Model Application Publication No. 58-13034, for example, the first guide is bent so that the vertical width of the focusing part is larger than that of the forced transfer path. It was hot.

[Problem to be solved by the invention]

Therefore, in the forced transfer route, the vertical width can be made small so that the stem culm bundles can be transported in a state that does not "come apart", while in the convergence section, although the advantage is that large bundles can be tied without loosening, If the stem culms supplied to the unit were not collected in a predetermined amount and an impact was applied to the sensing door due to machine vibration or the like, the binding device would operate unexpectedly and large bundles could not be tied.

In view of the above-mentioned circumstances, an object of the present invention is to provide a rational and simple improvement to the convergence unit, to properly operate the function of the sensing door, maintain the stem culm convergence function well, and to make the stem culm into large bundles. The purpose is to make it possible to tie the knots without loosening them.

[Means to solve the problem]

The characteristic configuration of the present invention is that the convergence section is provided with a second guide which is preferentially supplied with stem culms to the upper part thereof and can be freely retracted to the lower first guide side by the pressing action of the stem culms in the latter stage of convergence. Its functions and effects are as follows.

[Effect]

In other words, the stem culms are sent to the collecting part through a forced transfer path whose vertical width is smaller than that of the collecting part, and in the collecting part, the stem culms being conveyed are guided by the second guide to the upper side of the collecting part, which has a wider vertical width. 1st
It is guided toward the guide and focused from the top of the focusing section. As the focusing progresses, the second guide moves toward the lower first guide in accordance with the amount of focusing due to the pressing action of the focusing pressure of the focusing stem culm, and when a predetermined amount of focusing is reached, the focusing stem The culm presses against the sensing door.

〔Effect of the invention〕

By providing a second guide that can be freely retracted downward by a pressing action, the stem culms sent from the transfer system are pushed into the convergence part in an orderly manner from the upper side, and are properly and densely gathered. It is possible to converge without sticking, and as the second guide retires, the converging stem culm can be appropriately pressed against the sensing door, and regardless of the vertical width change of the converging part, the converging stem culm of the bundling device can be A highly practical stem culm bundling that can maintain good focusing function, has excellent stem culm bundling performance and is extremely advantageous for the post-processing of tied stem culms, with an extremely simple improvement of just adding a second guide. We have now been able to provide the device.

〔Example〕

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

The drawing shows a tying device that binds and releases the threshed waste straw transported and supplied in a horizontally suspended position by a clamping conveyance chain 2 installed in the threshing device 1 in a set amount. A rotary packer 3 that scrapes through the path A to the side of the bundle B that is continuous thereto, a needle 4 that winds the binding cord l around the bundle discharge straw, a knot building 5 and a cord holder 6 that tie and operate the wound cord l, and , various devices such as the arm 7 for discharging bundled waste straw are arranged above and below the collecting part B, and the collecting part B
A door 8, which closes the discharge opening of the waste straw, is provided so as to be able to swing downward and open freely while also being used as a sensor for detecting the pressing force of the waste straw.
When the pressing force of the focused and discharged straw against the door 8 exceeds the set value, the needle 4, the building 5, the holder 6, the door 8, and the discharge arm 7
are configured to be activated at predetermined activation timings.

The forced transfer route A is guided by two upper and lower first guides 9.
a, 9b, and the terminal end of the upper first guide 9a in the direction of conveying the waste straw, that is, the converging part B
By bending the part corresponding to upward, the focusing part B is formed so that its vertical width W ₁ is the vertical width W ₂ of the forced transfer path A.
This makes it possible to collect and bind a large amount of waste straw into a state as close to a round bundle as possible, and the so-called large bundle bundling can be performed without loosening of the tying string due to the round bundle shape. It is designed to work well.

A sled-shaped elastic second guide 1 is provided in the focusing portion B.
0 is arranged in an inclined position such that the freely swingable rear end is located at the upper side of the converging section B, and the upper surface thereof faces the terminal end of the transfer path A, and the lower end thereof is located at the lower end. Connected to the first guide 9a, the waste straw sent from the transfer path A at the initial stage of convergence is
The upward elastic pressing action of the second guide 10 feeds the waste straw preferentially to the upper side of the focusing section B, and the waste straw sent in in the latter stage of focusing is focused by elastically retiring the guide 10 downward using the pushing action. It is configured to be supplied to the lower side of section B.

In other words, the waste straw sent to the focusing part B at the initial stage of focusing is prevented from becoming an obstacle to the transfer of the waste straw that is continuously sent later, and the set amount of waste straw is delivered to the collecting part B in an appropriately dense state. The second guide 1
As described above, even though the vertical width _W1 of the focusing part B is made large, the focusing function and the , so as to maintain the sensing function of the door 8 at a high level.

[Another example]

Note that the specific expansion ratio W ₁ /W ₂ of the vertical width W ₁ of the converging section to the vertical width W ₂ of the forced transfer route A can be changed as appropriate, and the conveyed stem culm can be preferentially supplied to the upper part of the converging section B. At the same time, various improvements can be made to the specific shape, structure, and arrangement of the second guide 10, which retires downward due to the pressing force of the conveying stem culm in the latter stage of convergence.

The present invention is directed to a stem culm binding device for various uses such as for reaping stem culms and for threshing straw, which are installed in mobile reaping and harvesting machines, stationary threshing machines, and the like.
