Description

[Detailed description of the invention] The present invention relates to a stem culm binding device that binds a fixed amount of stem culms that are transported in a horizontally suspended posture in the same posture. In addition, we aim to provide a stem culm tying device that can stabilize the posture of the introduced stem culm by rationally improving the receiving support and thereby perform smooth tying work. .

Embodiments of the present invention will be described in detail below with reference to the drawings.

The figure shows a waste straw binding device 2 connected to the rear of a threshing device 1 mounted on a combine harvester. The straw is conveyed rearward by the straw discharge chain 3' and then discharged from the terminal end in a horizontal position, and is configured to be bundled as described below.

That is, as shown in FIG. 2, in the waste straw binding device 2, a transmission case 2a is located at a lateral side portion near the feed chain 3, and a transmission case 2a is located above and below the other lateral side portion away from the transmission case 2a. , a string supply section 2b equipped with a needle 4, a raking packer 5, etc., sandwiching an inclined path in which the stem culm is guided and conveyed diagonally downward in a horizontally suspended position;
Knot part 2C equipped with knot building 6, string holder 7, etc.
The stem culm convergence space B is formed between the string supply section 2b and the knot section 2C.

Further, between the terminal end of the straw removal chain 3' and the focusing space B, the conveyed stem culm is received and supported in a horizontal posture by a guide cover 8 and a guide rod 9 following the guide cover 8. Meanwhile, a conveyance mechanism 11 is constructed along the inclined path for conveying the tip side and the base side of the conveyed stem culm by an upper retaining conveyance device 10.10 and sending them into the convergence space B.

Then, the scraped straw sent in in a horizontal position by the conveying mechanism 11 is scraped into the gathering space B by the scraping packer 5, and after converging an appropriate amount, the string feeding operation of the two dollar 4 and the aforementioned operation are performed. It is arranged to bind by the knotting operation of the building 6 and release the bound stem culm to the rear.

Further, the guide rods 9 extend substantially along the inclined passageway into the stem culm focusing space B, and use their extended ends to direct the incoming stem culms into the focusing space B. It is constituted by a support part 9'... as a support for receiving it.

In addition, the support portions 9' are located below the binding position toward the stock base, and their receiving surfaces are at the binding position (especially on the lower edge knot portion 2C side). The holder 12 of the binding string a is located at a lower position as viewed from the rear toward the stock base.

The lower layer portion of the focused and discharged straw is supported in a state where the stock base part is slightly downward, and the upper layer portion existing above the lower layer portion is placed in a substantially straight line, and
In this way, since the stock head tends to fall and supports the discarded straw, the waste straw sent into this focusing space B tends to come first on the stock base side compared to the tip side. Not only does the space B expand, giving less sliding resistance to the stock base, but the guide rod 9 on the stock base side has a steeper downward slope than the guide rod 9 on the tip side, as shown in Figure 1, so the stock The base side will slide down first, and as a result, the waste straw that is sent into the focusing space B will tend to come first on the stock base side, and as a result, as shown in Figure 4,
With respect to the holder 12 that locks and holds the binding string a that is paid out from the tip of the needle 4 and whose end is supported by the holder 7, the above-mentioned In a state where the stem culm is received by pinching the binding string a, the plant side presses the binding string a toward the holding side while leading in the conveyance direction,
It is designed to prevent the string a from unexpectedly detaching from the holder 12.

In addition, in carrying out the present invention, the support 9 may be constructed of a guide plate-like member, and the point is that the receiving surface thereof is positioned downward from the binding position toward the stock base. You can configure it to do so.

Further, it is convenient if the receiving surface is configured to be adjustable in its lowering degree.

In summary, the stem culm binding device according to the present invention positions the string supplying part 2b above and the knotting part 2C below, sandwiching the inclined path in which the stem culm is guided and conveyed obliquely downward in a horizontally suspended position. In a stem culm binding device that binds stem culms in fixed amounts in the same posture, a support 9' for receiving and placing the imported stem culm from below in the stem culm convergence space B is placed almost along the inclined passage. The receiving surface of the binding string is placed on the side opposite to the side on which the knotted portion 2C is located in plan view with respect to the holder 12 of the binding string a provided on the lower edge knotted portion 2C side. a
In a state in which the stem culm is received by holding the stem, the base side of the stem is positioned lower as viewed from the rear from the position where the holder 12 is present so that the base side of the stem leads in the conveying direction. It is characterized by

In other words, since the base of the stem culm carried into the convergence space is received by the support in a position that is slightly lower than the intermediate part of the stem culm corresponding to the binding position, it is lowered than the intermediate part in the longitudinal direction of the culm due to convergence. It is possible to avoid the situation in which the stock base part, which has a large volume, bulges upwards more than the middle part, and it is possible to prevent the waste straw from accidentally slipping toward the tip side. As a result, it has become possible to bind the stems in a stable posture and perform the work without any mistakes in binding.

Note that the above configuration of the present invention is applied to a case where the conveyance path leading to the focusing space B is a downward slope as shown in the embodiment, so that the exhaust gas sent into the focusing space B is In the straw, the stock side tends to come first compared to the tip side, and as a result, as shown in FIG. When applied to a device having such an inclined conveyance path,
The effect brought about by the above-described configuration of the present invention, that is, the advantage that bundling errors are less likely to occur, is more clearly exhibited.
