Description

[Detailed description of the invention] Conventionally, in field work using a combine harvester equipped with a straw binding machine, the bundled waste straw was left in the field in a horizontal position, and the bundled waste straw was left in the field and was not allowed to rise. It could not be dried naturally by sunlight or ventilation.

Therefore, the inventor of the present invention first installed a bundled waste straw conveying device at an appropriate location of a combine harvester equipped with a waste straw binding machine, which receives the bundled waste straw from the waste straw binding machine and conveys it to an appropriate height position above the field. In addition, a bundled waste straw falling guide is arranged near the transport end of the bundled waste straw transporting device for guiding the bundled waste falling and discharged from the transport end in an upright position to fall in the vertical direction. A device for discharging bundled waste straw was developed to allow the bundled waste straw to be left in the field in an upright position, thereby allowing the bundled waste straw to dry naturally even when left in the field.

The present invention relates to an improvement of the Q bundled and removed straw discharging device which was previously developed by the present inventor as described above. This is intended to prevent various troubles from occurring due to unexpected clogging of bundled waste straw.

The bundled waste straw discharging device of the present invention that solves this problem is the above-described bundled waste straw discharge device, in particular, the bundled waste straw falling guide body is set at a guiding action position where the bundled waste straw can be guided to fall in the vertical direction. It is characterized in that it is configured to be freely displaceable between a guiding non-action position where guidance cannot be performed, and is biased and maintained at the guiding action position by an appropriate biasing holding means.

Next →Explaining the embodiment with reference to FIGS. 1 to 5. In the figure, 1 is a waste straw binding machine attached to the rear of a combine harvester 2, and this waste straw binding machine 1 is used to collect waste straw discharged from the combine harvester 2. A straw removal passage 3 is formed that slopes rearward and downward in communication with the discharge passage of the passage 3, and a knot part 4 and a discharge arm 5 are disposed above the terminal end of the passage 3, and a packer 6 and a needle 7 are provided below it. is arranged at the starting end of the straw passage 3 from the combine 2 to the uncut area (third direction).
The waste straw supplied in a horizontal position facing (to the left in the figure) is transferred to the end of the waste straw passage 3 by the action of the packer 6, and a certain amount of waste straw is collected at the end. The structure is similar to that of conventionally known straws, so that the needles 7 and the knot 40 act to bind the straw at a portion near the tip of the ear, and then the bundled straw is discharged rearward by the action of the discharge arm 50. It is something.

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, and the configuration of the bundled waste straw discharging device 8 in this embodiment will be explained below.

That is, from the vicinity of the knotting position at the end of the straw passageway 3, in the rearward upper direction and away from the uncut field (in FIG. 3,
A conveying chino 11 is installed in an inclined manner (to the right) through a chino case 9, and is driven to rotate in the direction of the arrow by power transmission from the waste straw binding machine 1 through the transmission case 10, and the chino case 9 A clamping plate body 15 is biased and supported by a support body 14 supported via a pair of U-shaped rods 12 and 13 so as to face the conveyance path of the conveyance chino 11, and a sandwich plate body 15 is attached to one end of the chino case 9. A pair of disc-shaped wrapping prevention bodies 16, 16 disable the conveying end rotation part of the conveying chino 11 from being conveyed, and a pair of disc-shaped wrap prevention bodies 16, 16 disable the conveying end rotation part of the conveying chino 11, and a pair of disc-shaped wrapping prevention bodies 16, 16 disposed on the uncut land side of the conveying chino 11 in the conveying direction of the chino 11. A bundling and waste straw conveying device 18 consisting of a straw bundling guide rod 17 that is sequentially inclined downward relative to the straw binding machine 1 is attached to the rear of the waste straw binding machine 1.

Therefore, according to this bundled waste straw transport device 18, the bundled waste straw discharged from the waste straw binding machine 1 is delivered to the starting end of the transport device 18, and the tip portion near the binding site is transferred to the transport cheno 11. It is conveyed rearward and upwardly while being held between the pinching plate body 15, but during this time, because the tip portion is being held and being slightly rotated due to the frictional resistance of the pinching plate body 15, the stock base portion is spread out in a conical shape, and furthermore, by the action of the stock head guide rod 17, the stock base portion is delayed in the conveyance direction and is sequentially changed downward, and the tip portion is moved by the U-shaped rod 12.1.
3 and will not be interfered with.

When the bundled waste straw is brought to the end of the conveying device 18, the pair of anti-wrapping bodies 16.16 ensure that it is removed from the conveying cheno 11 without being wrapped around the conveying chino 11. The stock is released by falling in an upright position substantially along the vertical direction with the base part spread out in a conical shape.

Furthermore, the bundled and removed straw conveying device 1 configured as described above is provided.
A falling guide body is provided near the end of the conveyance in step 8 for vertically guiding the bundled waste straw dropped and released as described above, thereby leaving the bundled waste straw in an upright position in the field. 19 are arranged as follows according to the present invention.

That is, in this embodiment, a vertically hanging pivot shaft 20 is protruded from a suitable position of the U-shaped rod 13 near the end of the conveyance, and a flat washer 21 and a snap pin 22 are attached to the pivot shaft 20. The rotary tube 23 is rotatably supported, a support body 19a consisting of a pair of rods of an appropriate length is fixed horizontally to the rotary tube 23, and the end of the support body 19a has an appropriate height and a horizontal cross-sectional shape. A bundled waste straw falling guide 19 consisting of a substantially U-shaped plate having a constant shape is fixed in such a manner that its lower edge is spaced from the ground by an appropriate distance longer than the length of the bundled waste straw, This falling guide 19 is placed around the rotation support shaft 20 in a guiding action position (the solid line position in Figure 1, the position shown by the solid line in Figure 4) in which it is close to the conveying end of the bundled and removed straw conveying device 18 and can surround it from behind. It is horizontally rotatable between the position indicated by the chain line) and the non-guidance position (position indicated by the chain line in Figure 1), where it is rotated by an appropriate amount in the direction of the mowed field from this position and does not surround the conveyance end. It is composed of:

Further, the U-shaped rod 13 is provided with a guide action position regulating pin 24 for locking the support body 19a and a guide in order to restrict the horizontal rotation displacement of the drop guide body 19 to the two positions described above. A non-operating position regulating pin 25 is fixedly attached to the supporting body 19a and the chain case 9 (or transmission case 10).
A tension spring 26 is removably interposed between the appropriate positions of the
The drop guide 19 is normally kept biased in the guiding position by the guiding position regulating pin 24 and the tension spring 26.

Then, the bundled waste falling guide body 19 is rotated by an appropriate amount from the guiding action position against the tension spring 26,
When the tension spring 26 passes over the rotation support shaft 20 (solid line in FIG. 4), the fall guide plate 19 is automatically rotated by the tension spring 26 to the non-guiding position. It is adapted to be held in position by being caught in the guide non-operating position regulating pin 25.

In the figure, reference numeral 28 denotes a separating claw 2 that can intermittently run across the straw removal passage 3 in accordance with the activation timing of the knotting part 4.
9, during the bundling operation, the separation claw 29 separates the collected waste straw that is being bundled from the collected waste straw that is likely to become entangled with the collected straw to be bundled next time.
This is designed to ensure reliable separation, so that the bundling and discharging functions of the waste straw can be performed well at all times.

Since the bundled waste straw discharging device according to the present invention is constructed as described above, its operation will be explained next with reference to the above-mentioned embodiment. The bundled waste straw is conveyed backward upward and toward the mown field, and is dropped and released from the end of the conveyance in an approximately vertical upright position with the plant base facing downward. The solid line in Figure 1 also indicates No. 4.
The bundled straw falling guide body 19 is biased and held in the guiding position shown by the chain line in the figure, that is, the bundle is formed into a substantially U-shape and is in a vertical position so as to be able to closely surround the terminal end of the conveying device 18. The conveying device 1 is moved by the waste straw falling guide 19.
Regardless of the impact when released from the end of 8, the bundled and removed straw will be guided to fall vertically, so it will always remain in an upright position or become upright. The posture of the plant is changed and the plant is allowed to fall onto the mowed field, and the plant is left standing on the mowed field with the stem part spread out in a conical shape.

At this time, since the lower end edge of the falling guide 19 is located above the bundled waste straw that stands up on the cut ground, as the combine 2 moves forward, the bundled waste straw that has been left upright can be removed from its tip portion. There is no possibility that the falling guide body 19 will interfere with the falling guide body 19 and fall down.

Therefore, since the bundled waste straw is left upright in the field in a conical and dispersed posture, the natural drying of the bundled waste straw can be carried out extremely well.

By the way, in the operation of discharging bundled waste straw by the bundled waste straw discharging device 8 as described above, it depends on various conditions such as the conveyance state of the bundled waste straw by the bundled waste straw conveying device 18 or the properties of the bundled waste straw itself. Then, the bundled waste straw is transferred to the conveying device 18.
transport end and a bundled straw falling guide 19 in the vicinity thereof.
You may get stuck unexpectedly between the two.

Once the bundled waste straw becomes clogged, the bundled waste straw that is sequentially transported by the transport device 1.8 will be retained at the end of the transport, resulting in various problems such as damage to the drive mechanism of the transport device 18. There is a risk of trouble occurring.

However, in the bundled waste straw discharging device 8 according to the present invention, the falling guide body 19 is energized and held at the guiding position where it can guide the bundled waste straw to fall as described above. When the waste straw is about to become clogged, the waste straw is bundled and the falling guide 19 is moved around the pivot shaft 20 against the tension spring 26 to reduce the distance between the end of the conveying device 18 and the falling guide 19. By rotating and displacing it in the direction that dogs can tighten (direction A), clogging of the bundled waste straw is prevented.

When the bundled waste straw is allowed to fall, the fall guide 19 is automatically returned to the guiding position by the tension spring 26.

In addition, if the condition of clogging of the bundled waste straw is severe or the volume of the bundled waste is extremely large, the falling guide body 19 is moved to a position where the tension spring 26 exceeds the pivot point, that is, the pivot shaft 20 (for example, the position shown by the solid line in FIG. 4). ), the falling guide 19 is then automatically moved by the tension spring 26 to a non-guiding position (the first
It is rotated to a position indicated by a chain line in the figure, and is held at that position by a guide non-operating position regulating pin 25.

In any case, since the bundled waste straw falling guide 19 is rotated as described above, it is possible to prevent the bundled waste from accidentally getting stuck between the end of the bundle and waste straw conveying device 18 and the fall guide 19. This can be prevented.

Therefore, according to the discharging device 8 according to the present invention, the work of discharging the bundled waste straw can always be performed satisfactorily without causing various troubles due to clogging of the bundled waste straw.

Note that the spring force of the tension spring 26 and the tension spring 26
The position of the falling guide 19 when the straw passes through the rotation support shaft 20 (solid line position in Figure 4) should be set appropriately so that the best discharge operation of the bundled waste can be performed. Of course there is.

Further, the guiding position where the falling guide 19 can guide the bundled waste straw to fall, and therefore the distance between the end of the conveying device 18 and the falling guide 19, is set appropriately in advance according to the properties of the bundled waste straw. However, instead of the guiding action position regulating pin 240 in the above embodiment, as shown in FIG. 32, and if the adjustment bolt 30 is configured to arbitrarily adjust the position where the tension spring 26 of the drop guide 19 is held, the properties of the bundled waste straw, such as large or small volume, can be adjusted according to the soft shell. This is advantageous because it is possible to set the most appropriate guiding position of the fall guiding body 190 depending on the conditions of the culm and the like.

In the above-described embodiment, the bias retaining means for biasing and retaining the drop guide 19 at the guiding position is constituted by the tension spring 26 and the guiding position regulating pin 24 (or adjustment bolt 30). However, in other implementations, as shown in FIGS. 7 and 8, for example, the fixing pin 33 is attached to the drop guide 10 (or support 19a), and the stopper pin 34 is attached to the anti-wrapping body 16 (or chain case 9). ) may be configured to be held under pressure by a spring plate 36 attached to the spring plate 35. In this case, when the bundled waste straw is about to become clogged, the retaining pin 34 is released from the spring plate 36 by the spring plate 36. It comes off against the pressure holding force, and the falling guide 19 returns to the guiding position (seventh position).
The guide is rotated from the solid line position in the figure to the non-guiding position (the chain line position in the figure), and the same effects as in the above embodiment can be achieved.

In each of the embodiments described above, it goes without saying that the work of attaching and detaching the drop guide 19 and the bias holding means is extremely easy.

In any case, as is clear from the above explanation, the bundled waste straw discharging device of the present invention reliably transports the bundled waste straw dropped from the bundled waste transport device to the field in an upright position. In order to leave the bundled waste straw alone, that is, to guide the bundled waste straw to fall in the vertical direction in an upright position, the bundled waste straw falling guide body, which is provided in close proximity to the conveyance end of the conveyance device, is normally operated by an appropriate biasing and holding means. The bundled waste straw is energized and held in a guiding position where it can be guided to fall, and if the bundled waste straw becomes unexpectedly stuck between the end of the conveying device and the falling guide, the bundled waste straw is removed. Since the structure is such that the falling guide can be moved to a position where the clogging can be prevented, the bundled waste may accidentally become stuck between the end of the conveying device and the falling guide, causing various problems. It is extremely easy to work with, as it can reliably prevent the occurrence of such troubles, and can always perform the work of discharging the bundled waste straw in a good and safe manner.
