Description

[Detailed description of the invention] [Industrial field of application] This invention transports the bundled waste straw discharged from the waste straw binding machine installed at the rear of the combine to the already cut field side on one side of the transfer machine body. This invention relates to a bundled straw conveying device for a combine harvester that discharges bundled straw.

[Prior art]

The bundled waste straw discharged from the straw binding machine installed on the combine harvester is now transported to the already cut field side on one side of the combine harvester and released by the bundle removal straw conveying device when normal round mowing work is possible. However, in the process of cutting through the inside of the erected grain culm, commonly known as splitting, it is not possible to release it to one side of the machine where the erected grain culm exists, so in this case, it is released from the straw binding machine. It is necessary to directly discharge the bundled waste straw to the rear of the aircraft without having to transfer it using a bundled waste straw transport device.

For this reason, in the conventional splitting operation, the entire pinching rail, which is disposed opposite to the endless conveying belt of the bundled straw conveying device, is moved upward to be rendered inactive. In addition, as in Japanese Utility Model Application Publication No. 58-192544, a part of the starting end side of the pinching rail installed opposite to the endless conveyor belt of the bundled straw conveying device is divided into a bundled straw receiving and clamping position and a non-receiving and clamping position. A device has been proposed that can be switched and fixed freely over a period of time.

[Problem that the invention attempts to solve]

However, the above-mentioned method of moving the entire pinching rail opposite to the endless conveyance belt of the bundled straw conveying device upwards, and the method disclosed in Utility Model Application Publication No. 58-192544, do not use the pinching rail or the pinching rail. The starting end of the shedding rail is in a non-operating state, largely retracted upwards from the endless conveyor belt, and cannot guide the bundling culm discharged from the straw tying machine. There is a problem in that this creates resistance and prevents smooth rear ejection.

Therefore, the present invention was devised to solve the above-mentioned problems, and an object of the present invention is to provide a bundled waste straw conveying device for a combine harvester that can smoothly discharge the bundled waste straw backwards.

[Means for solving problems]

In order to achieve the above object, the present invention provides a bundled straw conveying device that transports and releases the bundled waste straw discharged from the straw binding machine to the mown field side on one side of the transfer machine body, and also The starting end rail of the pinch rail installed opposite to the endless conveyor belt of the straw conveying device is used to transfer the bundled waste straw to the bundled waste straw transporting device, and the guide in which the bundled waste straw moves on the starting end rail. This structure constitutes a bundled straw conveying device for a combine harvester, which can be freely switched and fixed in different postures.

[Effect]

Therefore, with the starting end rail switched to the transfer position, the bundled culm discharged from the straw binding machine is
Although it can be transferred to the bundled waste straw conveyor and transported to the mowed field side on one side of the machine as before, the starting end rail that has been switched to the guiding position allows the bundled waste discharged from the straw binding machine to be transferred to the mowed land side on one side of the machine body. The culm is moved and guided on the starting end side rail, and can be smoothly discharged backward without coming into contact with the starting end side of the endless conveyance belt and creating resistance.

〔Example〕

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

As shown in FIGS. 4 and 6, the combine 1 is moved by a traveling device 3 consisting of a pair of right and left crawlers 2, 2, and a machine platform 4 disposed above the traveling device 3. A pre-processing device (not shown) is installed in front of the pre-processing device, and a threshing device 5 is mounted on the machine platform 4 behind this pre-processing device, and the grain culms cut by the pre-processing device are The grains are conveyed toward the rear threshing device 5 and are threshed by the threshing device 5.

The straw that has been threshed by this threshing device 5 is conveyed by a straw conveying device 6 that extends diagonally backward from the end of the handling drum (not shown) of the threshing device 5, and is discharged at the end. be done. This waste straw slides down the downwardly sloping bundling passage 7, and when it reaches a predetermined amount, it is bundled by the unillustrated bundling mechanism of the waste culm bundling machine 8, and then discharged backward by the sweeper 9 of the waste culm bundling machine 8. It's getting old.

As shown in detail in Figures 3 and 5,
Further, at the rear of the straw tying machine 8, there is a tying and discharging straw conveying device 10 that takes over the tying and discharging straw discharged from the straw tying machine 8, and conveys it to the mowing field side on one side of the machine body and discharges it. It is provided. This bundled straw conveying device 1
0 includes an endless conveyance chain 11 whose starting end is located behind the sweeper 9 of the straw tying machine 8 and whose terminal end faces the cut field side on one side of the machine body, and a pincher installed opposite to the conveyance side of this endless conveyance chain 11. A clamping rail 12 is provided, and the axis P of the clamping rail 12 is located above the upper surface of the endless conveyance chain 11. This pincer rail 12 is movably supported on the pincer table 13 via a spring (not shown) on the pincer table 13 side.
This clamping table 13 and a support frame (not shown) that rotatably supports the endless conveyance chain 11 are integrally connected via an inverted U-shaped connection frame 14 that extends high upward. There is.

A starting end side rail 15 is connected to the starting end side of the pinching rail 12 and extends toward the binding path 7 side while being curved so that the starting end thereof gradually moves away from the starting end of the endless conveyance chain 11 in a transporting attitude U, which will be described later. This starting end side rail 15 is provided so as to be rotatable and fixed via a switching device 20 between the conveying position of the bundled waste straw and the guiding position of the bundled waste straw around the axis P of the pinching rail 12. This switching device 20 is constructed as follows.

That is, as shown in detail in FIGS. 7 and 8, a fan-shaped plate 16 whose base end is fixed to the shaft end on the starting end side of the pinching rail 12 is provided, and the expanding side of this fan-shaped plate 16 is , two screw holes 17 are provided at a predetermined angle. Further, a center shaft 18 that fits into the inner diameter of the pinching rail 12 is fixed to the terminal end shaft end of the starting end rail 15, and a base end of a switching lever 19 that slides on the fan-shaped plate 16 is fixed, and this switching lever A hole into which a butterfly bolt 21 is inserted is formed on the extension side of the lever 19.

Therefore, by rotating the switching lever 19 up and down about the axis P of the pinching rail 12 with the butterfly bolt 21 removed, the starting end side rail 15 integrally connected thereto can be moved to the first position. As shown in FIG. 8, it is possible to selectively switch between the transfer position U, which rises to the solid line position, and the guide position D, which descends to the chain line position. It can be fixed by Then, the bundled waste straw that is released is transferred to the endless conveyor belt 11 and the pinching rail 1.
2, the starting end side rail 15, whose starting end rises significantly, crosses over the starting end side of the straw removal conveying chain 11 as shown in FIG. 4 by switching to the guiding attitude D. Its starting end is located below the rear end of the door 40 when the straw binding device 8 is in the discharged state (lowered down).

In the case of splitting work, the starting end rail 15, which is switched and fixed to the guide position D shown by the chain line, crosses the upper part of the starting end side of the straw removal chain 11, and its starting end is located below the door 40. , Figure 2A
The bundled waste straw H discharged from the waste straw binding machine 8 as shown in
is guided while moving on the starting end side rail 15 in the lowered position, so that it can be smoothly discharged backward without coming into contact with the starting end side of the endless conveyance chain 11 and creating resistance.

In addition, in the case of normal work, by switching and fixing the starting end side rail 15 to the transfer device U shown by the solid line,
The bundled waste straw H discharged from the waste straw binding machine 8 is
As shown in Figure B, by moving along the curved surface while being received by the starting end side rail 15 in the raised position, the straw is smoothly transferred to the starting end side of the endless conveying chain 11, and the straw is collected by the bundled straw conveying device 10. After being conveyed to one side of the machine body in a hanging state, it is released from the end and can be dropped onto the mowed land side.

The bundled waste straw conveying device 10 is configured to be switchable and fixed between a transfer position in which the bundled waste straw is transported to one side of the machine body and a storage position in which the bundled waste straw is not transported. That is, as shown in detail in FIGS. 3 and 5, a first fixed seat 25 extending upward and having a screw hole is fixed above the U-shaped connection frame 14. The connecting rod 26 whose rear end is fixed downward extends forward, and a second fixing seat 27 having a screw hole is fixed to this extended end. In addition, these fixed seats 25 and 2
A mounting seat 28 for fixing the handle 7 protrudes from the body side, and this mounting seat 28 is provided with a through hole into which a mounting screw 29 with a handle can be inserted.

Therefore, when the first fixing seat 25 is fixed to the mounting seat 28, the straw binding and discharging conveying device 10 has the starting end of its endless conveying chain 11 moving away from the sweeper 9, leaving the rear side of the straw discharging and binding machine 8 in an open state. None It can be fixed in a retracted position with its terminal end approaching the aircraft. In this stored state, as the bundled straw conveying device 10 moves, the terminal end of the endless conveyance chain 11 and the starting end side rail 15 move integrally while maintaining their relative positions. 15 to the guiding attitude D, the bundled waste straw H discharged from the waste straw binding machine 8 is moved and guided on the starting end side rail 15 which is in the guiding attitude, and is transferred to the endless conveyor chain as described above. It is designed so that it can be smoothly discharged backwards without coming into contact with the starting end side of 12 and creating resistance.

In addition, when the second fixed seat 27 is fixed to the mounting seat 28, the straw binding and discharging conveying device 10 is tilted so that the starting end of the endless conveying chain 11 is close to the sweaver 9 of the straw discharging and binding machine 8, and the terminal end is away from the machine body. It can be fixed in the transfer position where it is extended in the posture. In the transfer posture of this bundled and discarded straw conveying device 10, by switching and fixing the start end side rail 15 to the transfer position U, the bundled and discarded straw H discharged from the straw and waste bundling machine 8 is
As described above, the straw is smoothly transferred to the starting end side of the endless conveying chain 11, and after being conveyed by the bundling straw conveying device 10 in a hanging state with the stock side facing downward, it is conveyed to the mowed land side on one side of the machine, and then at the terminal end. It is designed to be released by falling.

When the bundled waste straw transport device 10 is in an oblique position, by providing the resistance rod 37 on the bundled straw transport device 10, the bundled waste straw transported by the resistance rod 37 is rotated and the stock side is expanded. As a result, the bundled waste straw falls vertically with the plant base downward and stands upright in the field, thereby promoting drying of the bundled waste straw.

Furthermore, in the stored state of the bundling and discharging straw conveying device 10, the transmission case 35 on the side of the bundling and discharging conveying device 10 that drives the endless conveyance chain 11 is separated from the transmission case 36 on the side of the straw discharging and binding machine 8, thereby generating power. transmission is now cut off. On the other hand, in a transfer state in which the straw binding and discharging transport device 10 is in an oblique position, the transmission case 35 on the side of the bundling and discharging straw transport device 10 is connected to the transmission case 36 on the straw discharging and binding machine 8 side, thereby transmitting power. is now being carried out.

Further, as shown in detail in FIGS. 1 and 4, an inverted U-shaped connecting frame 14 that approaches the straw tying machine 8 when the straw tying and discharging conveying device 10 is switched to the storage position is utilized. A tip-side resistance rod 38 is provided on the side of the straw binding machine 8 of this connection frame 14, which acts only when switched to the storage position.
By applying resistance to the tip side of the bundled waste straw discharged by the tip side resistance rod 38, the bundled waste straw can be discharged in an orderly manner in a vertical position during rearward discharge.

[Effect of idea]

In short, the bundled waste straw conveying device for a combine harvester according to the present invention has a bundled waste straw installed at the rear of the combine that transports the bundled waste straw released from the straw removal binding machine to the already cut field side on one side of the transfer machine body and releases it. In addition to providing a straw conveying device, the starting end rail of the pinching rail, which is installed opposite to the endless conveying belt of this bundled and discarded straw conveying device, is configured to be used in a transfer posture for transferring the bundled and discarded straw to the bundled and discarded straw conveying device, and in a bundling and discharging position. Since the straw can be switched between the guide position and the guide position in which the straw moves on the starting end rail, the bundled and discarded culms are transferred to the bundled and discarded straw conveying device in the same manner as before by the starting end side rail that has been switched to the transfer position. Although it can be transported to the mown field on one side of the machine, the starting end rail that has been switched to the guiding position guides the bundled waste culm released from the straw binding machine as it moves on the starting end rail. It can be smoothly discharged backward without coming into contact with the starting end side of the endless conveyance belt and creating resistance.
