Description

[Detailed description of the invention] Generally, in field work using a combine harvester equipped with a waste straw binding machine, the bundled waste straw is left in the field in a horizontal position.

Therefore, as it is, it is difficult to completely dry the bundled waste straw naturally by sunlight and ventilation.
Conventionally, in order to obtain dried waste straw, some kind of additional drying operation was inevitably required.

In view of the above-mentioned circumstances, the present invention provides a new bundled waste straw discharging device that can make the bundled waste straw discharged from a combine harvester equipped with a waste straw binding machine stand up in the field, so that the bundled waste straw can be left standing in the field. It was designed to allow good natural drying.

The bundling and waste discharging device of the present invention solves the above problems,
A bundled waste straw conveying device that receives the bundled waste straw from the waste straw binding machine and transports it to an appropriate height position above the field is installed at an appropriate location of the combine harvester equipped with a waste straw binding machine, and the bundled waste straw conveying device Near the end of the conveyance, so as to be able to surround it at an appropriate distance from the end of the conveyance device in order to guide the bundled waste straw falling and discharged from the conveyance end of the bundled waste straw conveyance device in an upright position in the vertical direction, The present invention is characterized in that a vertical bundled waste straw falling guide body whose horizontal cross-sectional shape is U-shaped from the direction opposite to the direction of transport of the bundled waste straw is provided.

Next, an example will be explained with reference to the figures. In the figure, 1
is a straw tying machine attached to the rear of the combine harvester 2, and this straw tying machine 1 has a sloping straw passage 3 extending rearward and downward in communication with the discharge path of the straw discharged from the combine 2. As a result, there is a building above the end of the straw passageway 3.
A knotter 4 equipped with a holder and a discharge arm 5 are disposed, and a packer 6 and a needle 7 are disposed below them, and the stock is placed at the starting end of the straw passage 3 from the combine harvester 2 to uncut land. The waste straw supplied in a horizontal position facing is transferred to the end of the waste straw passage 3 by the action of the packer 6, and when a certain amount of waste straw is collected at the end,
The structure is similar to that of a conventional one, so that the needles 7 and the knot 4 bind the straw at a portion near the tip of the ear, and then the bundled straw is discharged rearward by the discharge arm 5. ing.

Reference numeral 8 denotes a bundled waste straw discharging device according to the present invention, which is installed at the rear of the waste straw binding machine 1. The configuration of the bundled waste straw discharging device 8 in this embodiment will be explained below.

That is, it is stretched in an inclined manner from the vicinity of the knotting action site at the end of the straw passageway 3 toward the upper rear and away from the uncut land (to the right in FIG. 3), and the power is transmitted from the straw binding machine 1. a conveying endless belt 9 that is driven to rotate in the direction of the arrow; and a pinching body 10 that is disposed oppositely along the conveying path of the endless belt 9;
A bundling and waste straw conveying device 12 comprising a stock head guide rod 11 disposed on the uncut land side of the endless conveying belt 9 and tilted sequentially downward with respect to the conveying path of the endless belt 9 is removed. It is attached to the rear part of the binding machine 1 via an appropriate attachment means.

The clamping body 10 is constructed by connecting a plurality of links in series so that the bundled waste straw having a large diameter can be continuously and satisfactorily clamped between it and the endless transport belt 9. There is.

Therefore, according to this bundled waste straw transport device 12, the bundled waste straw discharged from the waste straw binding machine 1 is transferred to the transport device 1.
2, and is conveyed backward and upward while the tip part near the binding part is held between the conveying endless belt 9 and the clamping body 10; As the stock is slightly rotated due to the frictional resistance of the clamping body 10, the stock base is spread out into a conical shape, and further, due to the action of the stock base guide rod 11, the stock base is delayed in the conveying direction and is moved downward. She is forced to change her posture.

The bundled waste straw is then dropped and discharged from the terminal end of the conveying device 12, but at this time, the stock part is in an upright position along the vertical direction with the stock part spread out in a conical shape.

Furthermore, the bundled and removed straw conveying device 1 configured as described above is provided.
In the vicinity of the conveyance end of No. 2, a bundled waste straw falling guide 13 as described below is disposed.

That is, in this embodiment, the bundled waste straw falling guide body 13 is constituted by a substantially U-shaped plate having an appropriate height, and the conveying end of the bundled waste straw conveying device 12 is then With a nearly vertical posture so that it can be surrounded from all sides,
It is attached to the machine frame of the bundled and removed straw conveying device 12.

That is, the cylinder whose upper end is rotatably attached 15 to a support rod 14 fixed to the machine frame of the bundled and removed straw conveyor 12, and whose lower end is rotatably fixed to the machine frame by being fitted with a bolt 16. It is fixed to a support rod 18 inserted through the body 17.

A bolt 19 for fixing the support rod 18 is screwed into the cylinder 17 so that the attitude of the drop guide 13 can be changed and adjusted.

By positioning the terminal end of the bundled and removed straw conveying device 12 at an appropriate height above the cut surface and by setting the height of the falling guide 13 appropriately,
The lower end 13a of the falling guide 13 is spaced apart from the cut ground by a distance slightly longer than the length of the bundled waste straw.

In the figure, reference numeral 20 denotes a separation claw 2 that can intermittently run across the straw removal passage 3 in accordance with the activation timing of the knotting part 4.
1, during the bundling operation, the separating claw 21 separates the collected waste straw that is being bundled and the waste straw that is likely to get tangled with the collected straw to be bundled next time.
The purpose is to ensure that the waste straw is separated properly, so that the bundling and discharging functions of the waste straw are always performed satisfactorily.

Next, to explain the operation of the above embodiment, when the combine harvester 2 is used to perform field work, the straw binding machine 1
The tip of the bundled waste straw released from the bundle U [
The straw is transferred to the starting end of the straw conveying device 12 and transported rearward and upward, and its root portion is spread into a conical shape by the pinching and conveying action of the endless conveying belt 9 and the pinching body 10 and the action of the straw head guide rod 11. The straw is placed in an upright position along the substantially vertical direction, and is then dropped and discharged from the transport end of the bundled and removed straw transport device 12 with its base facing downward.

At this time, the bundled waste straw falling from the bundled waste straw transporting device 12 is formed into a substantially U-shape that can surround the terminal end of the transporting device 12, that is, it can surround the bundled waste straw from the direction opposite to the transport direction. The vertical drop guide 13 guides the transport device 12 so that it falls vertically, regardless of the impact caused when it is released from the end, so it always remains in an upright position. The stalks are allowed to fall onto the already mown field, and are therefore reliably erected on the previously mown field with the base portions spread out in a conical shape.

Since the lower end 13a of the falling guide body 13 is located above the bundled waste straw that stands up on the cut ground, as the combine 2 moves forward, the raised bundle waste straw is guided to the tip portion of the fall guide. There is no risk of the body 13 interfering and knocking it down.

In this way, the bundled waste straw is successively erected in the field in a conical and diffused posture, so that the natural drying of the bundled waste straw is performed extremely well.

Further, in the above embodiment, the falling guide 13 is installed in a substantially vertical state, but by operating the bolts 19 etc., the posture of the falling guide 13 can be adjusted and
The structure is such that the position relative to the end of 2 can be changed and adjusted, and this change adjustment is the most suitable for raising the bundled waste straw on the already cut field according to various conditions such as the size of the bundle of bundled waste straw. This is done as appropriate to provide a fall guiding effect.
The same procedure as described above is also carried out when the bundled waste straw transport device 12 is configured to change and adjust the transport end position depending on the length, etc. of the bundled waste straw.
By performing the posture change in step 3, a guiding action can be performed so that the bundled waste straw can always fall in the vertical direction under any conditions.

In the above-mentioned embodiment, the bundling and waste straw discharging device 8 is a waste straw tying machine 1 that is attached to the rear of the combine harvester 2, which is capable of tying the straw in a horizontal position with the stem facing toward the uncut field. We have shown an example of a combine harvester equipped with a straw tying machine, but
The bundling and waste straw discharging device according to the present invention is applicable not only to the above-mentioned type of combine with a waste straw tying machine, but also to a combine harvester in which a waste straw tying machine is attached to the side of the combine, or a waste straw tying machine is used to vertically tie the waste straw. The device can be installed in all types of combine harvesters with a tying machine, such as those configured to be able to bundle in an upright position along a direction or in a horizontal position with the tip facing the uncut field.

Further, in the above embodiment, the bundled and removed straw conveying device 12
In other words, although an example is shown in which the endless conveying belt 9 is stretched upwardly and rearward in an inclined manner, the installation position and orientation of the bundled and removed straw conveying device 12 are different from those of the bundled and removed straw tying machine installed in the bundled and removed straw discharge device 8. It is set appropriately depending on the type of combine.

Furthermore, at the end of the conveyance of the bundled and removed straw conveying device 12, the bundled and removed straw is configured to be in an upright position along the substantially vertical direction by the action of the stock guide rod 11; Even if this is not the case, it is not necessary to provide the stock head guide rod 11 because the falling guide member 13 can guide the bundled waste straw to fall so as to stand up on the field.

In any case, as is clear from the above explanation, the bundled waste straw discharge device of the present invention transports the bundled waste straw discharged from the combine harvester with the waste straw binding machine to the upper part of the field using the bundled waste straw conveying device. A vertical falling guide body 13 formed in a U-shape from the direction opposite to the conveying direction of the conveying apparatus is brought to an appropriate height position and can surround the terminal end of the conveying apparatus at an appropriate interval. Regardless of the impact etc. when the end of the conveying device 12 is released due to the action, the conveying device 1
2, the waste straw released from the end of the field is reliably guided so that it falls vertically and falls onto the cut field while maintaining an upright posture, thereby ensuring that the bundled waste straw released into the field is in an upright state. can do.

Therefore, according to the device of the present invention, even if the bundled waste straw is left in the field, it can be air-dried effectively, and there is no need for a separate drying operation as in the past, and the drying process is efficient and good, resulting in long straw that has great commercial value. You can get it.
