The purpose of this is to simplify the support mechanism of the bundled waste discharge device.

The present invention provides a bundled waste straw conveying means for receiving the bundled waste straw from a waste straw binding machine and immediately transporting it to an appropriate height position above the mowed field, and a bundled waste straw being conveyed by the bundled waste straw conveying means. In the bundled waste straw discharging device, the bundled waste straw discharge device includes a posture changing means for making the bundled waste straw falling and discharged from the terminal end of the bundled waste straw transporting means into an upright posture, the waste straw transporting means is installed to extend toward the rear of the machine body. A device for discharging bundled waste straw, characterized in that its rear part (conveying end part) is supported by a support pipe, and its middle part is supported by a transmission tube equipped with an electric shaft for transmitting power to a waste straw conveying means. It provides:

The present invention will be described below based on embodiments shown in the drawings.

A straw binding machine 2 is connected to the rear of the combine harvester 1, and the waste straw from the threshing device is supplied onto a straw deck 3 in an almost horizontal state by a straw conveying chain (not shown) of the combine harvester 1. It is tied horizontally. The joint part 4 such as a bill holder and the discharge arm 5 are located above the straw deck 3, and the pack car 6, needle 7, etc. are located on the straw deck 3.
It is located below. 8 is a transmission case of the binding machine, 9 is a door, and 10 is a stock shutter that supports the straw being bundled.

Reference numeral 11 denotes a waste straw separating device for distinguishing between unbound waste straw and tied waste straw, and a protruding piece 13 projected by a chain 12 that rotates in conjunction with the operation of the knotting section 4 This prevents the stock part of the waste straw that will be tied up next time from falling.

Next, the bundled and removed straw conveying device 14, which is the main part of the present invention, will be explained.

A driving sprocket and a driven sprocket are rotatably attached to both ends of the transport case 15, and a transport chain 16 is wound around both sprockets.
The second transmission case 17 is fixed to the back side of the binding machine 2, and the first transmission case 18 is fixed to the side of the transmission case 8 of the binding machine 2. Transmission cylinder 1
9, and a support pipe 20 is fixed to the distal end of the transport case 15 and the base end of the first transmission case 17, and power is obtained from the input shaft to the binding machine 2 to connect the first transmission case 18. Transmission tube 19 Second transmission case 17
The drive sprocket in the transport case 15 is driven through the support pipe 20 and the transmission cylinder 19, and the transport case 15 is fixedly supported at a predetermined angle and position. In the embodiment, the rear end 15b of the transport case 15 is located above the front end 15a, and the front end 15a is located near the extension line of the binding path of the binding machine 2 in plan view (see FIG. 1). Rear end 15
b is located on the side of the machine (already mowed land side) and is transport case 1.
5 is installed diagonally toward the rear mown field side. Also,
The transport case 15 is at its upper end (transport chain action side)
It is inclined upward and inward with respect to the vertical plane so that it faces inward. One end of the U-shaped pipes 21, 21 is fixed to the transport case 15, and a support plate 22 is fixed to the other end, so that the support plate 22 faces the transport chain 16 at the upper end of the transport case 15, and the clamping pressure is divided into a plurality of parts. Rod 23
A rod 25 having a pin 24 at its tip that connects each other is attached to the support plate 22 so as to be movable in the axial direction, and a compression spring 26 is inserted into the rod 25 to form a clamping rod 23 similar to the clamping rod in a feed chain. The construction is such that the gap between the conveying chain 16 and the clamping rod 23 is automatically changed according to the amount of waste straw being conveyed.

Next, the attitude changing means has an action part 27a located on a plane substantially perpendicular to the plane containing the transport case 15, and the distance from the support plate 22 increases from the front end 15a to the rear end 15b. Mandatory share price guide 2
7 is fixed to a support plate 22.

The intake guide 28 is attached to the front end (transportation start end) of the clamping rod 23, and the transport end side and the transport case 1 are
A winding prevention rod 29 is attached to the lower side of the transport case 17.
Fixed to. It goes without saying that the winding prevention rod 29 may be divided into two parts: an arc-shaped portion at the end of the conveyance and a straight portion at the lower end of the conveyance case 15.

Reference numeral 30 denotes a drop guide, which is fixed to the support plate 22 and the transport case 15 by mounting rods 31 and 32 so as to face the transport case 15 at the terminal end of the lifting transport, and is U-shaped in plan view and extends in a substantially vertical direction. The lower end 30a is set to be higher than the upper end of the bundled waste straw released into the field in an upright position.

Reference numeral 33 denotes a rod for relaying and supporting the stock base of the bundled waste straw that is being transferred from the binding machine 2 to the bundled waste straw conveying device 14.

Next, the action will be explained.

The bundled waste straw bundled and discharged by the binding machine is transferred from the waste straw deck 3 to the bundled waste transport device 14 by the discharge arm 5 as shown in FIG. 4, but at this time, the bundled waste straw is taken in from above. Guided by the guide body 28 and supported by the receiving rod 33, the tip portion is sent to the starting end of the conveying chain 16, and the stock base portion is moved more than the tip portion by the action of the discharge arm 5, as shown in FIGS. 5a and 5b. Then, as the tip portion is lightly held from above and below by the conveyance chain 16 and the base of the intake guide 28, it rolls and twists as it moves backward as the conveyance chain 16 rotates, causing the stock to become twisted. The base portion expands toward the end in a conical shape and is drawn toward the conveyance chain 16, resulting in the state shown in FIGS. 6a and 6b. Therefore, the movement changes from the state perpendicular to the bundling path shown in FIG. (movement using a circular arc as the locus of movement of the rear end of the stock).

As described above, the bundled and removed straw is transferred to the bundled and removed straw conveyance device 14, and while being held between the bundled and removed straw conveyance chain 16 and the clamping rod 23, it is lifted and transferred toward the side of the machine on the side of the mowed land at the rear of the machine. . At this time, the bundled waste straw is transferred to the conveyor chain 1 as shown in Fig. 7a and b.
It is almost perpendicular to the 6-pin pressure rod 23, and since only the tip portion is clamped, and because it is slightly rotated due to the frictional resistance with the 6-pin pressure rod 23, the root portion is spread out into a conical shape. Proceed to the end of transport.

Since the clamping rod 23 is divided into a plurality of parts, only that part of the clamping rod that is acting on the bundled straw is bent, so that the bundled waste straw being conveyed can be firmly and strongly clamped. There is.

As described above, the bundled waste straw is transferred by the bundled waste straw conveying device 14 toward the end of the conveyance, and the forced stock head guide body 27, which is the posture changing means of the present invention, gradually acts to push down the stock head part. The bundled waste conveying device 14 has a conveying chain 16 and a pressure rod 2.
3 acts only on the tip of the bundled waste straw that is being transferred, so that the tip gradually advances and the base of the stock becomes suspended, becoming almost vertical as shown in Figure 8. The original part is diffused into a conical shape.

That is, at the starting end of the bundled waste straw conveying device 14, the bundled waste straw is supplied in a substantially horizontal state, but at the terminal end, the attitude is changed to a substantially vertical direction.

The bundled waste straw transported in the vertical direction to the end of the bundled waste straw conveying device 14 in this manner is separated from the conveyance action in an upright position (vertical state in which the stock part is spread out in a conical shape and the stock head is directed downward). It falls vertically towards the already cut field. In addition, when transporting by the bundled straw transport device 14, the forced stock guide body 2
7 imparts transport resistance to the stock base, so the stock base is transported with a delay and a rotational or twisting action is applied, and this action increases as it reaches the terminal end, so that the bundling and discarding during transport is difficult. The posture is changed in the vertical direction and the shape becomes wider toward the end, thereby increasing the conical shape. In addition, when the bundled waste straw falls vertically, the stock head is regulated in the vertical direction by the falling guide 50, and the posture changing means (forced stock head guide) 2
7, the bundled waste straw falling from the terminal end of the bundled waste straw conveying device 14 is more reliably held in an upright conical posture.

In addition, at the terminal end of the bundled and removed straw conveying device 14, the conveying chain 16 is
A part of the bundled waste straw away from the terminal end is prevented from wrapping around the terminal end of the transport chain 16 and the transport chain 16 on the lower end side of the transport chain rotating in the reverse transport direction.

In this way, the bundled waste straw that has fallen vertically toward the harvested field is made to stand up with its base part spread out in a conical shape, and the natural drying of the bundled waste straw is carried out extremely well, as shown in Figure 9. As such, it is located behind the driver's cab, paddy holder, etc. located laterally than the traveling device 34, and is located so as not to obstruct the work of the next row of combine harvesters.

In the above-described embodiment, the bundled and removed straw conveying means is the bundled and removed straw conveying device 14 which is installed diagonally so that the rear side is higher. may be arranged horizontally or conversely so that the rear side is lower, and it is sufficient that the conveying end is located at a position suitable for vertically dropping the bundled waste straw. In addition, when viewed from above, the terminal end of the bundled and removed straw transport device 14 is installed obliquely so that it is located on the side of the machine on the mown field side, but it runs like a combine harvester with a driver's cab and a paddy holder at the rear of the machine. In cases where discharging the bundled waste straw to the rear of the machine within the width of the device does not interfere with the reaping work of the next row, the conveyance device 14 may be set in the machine advancing direction (the bundling path extension direction).

In addition, the transport case 1 of the bundled and removed straw transport device 14
5 has an inward inclination at the upper end (for example, 45 degrees), which is convenient because it simplifies the mechanism for changing the binding and shedding horizontally at the start end and vertically at the end, but it can also be used vertically. good.

In the embodiment shown in the drawings, the transmission tube 19 that houses the transmission shaft and the bevel gear is connected to the bevel gear box 19b that is fixed in the middle of the support pipe 20 and that houses the bevel gear, and the first transmission case on the side of the waste tying machine 2. 17 and bevel gearbox 19
A first cylindrical body 19a has an internal transmission shaft between it and the bevel gear shown in FIG.
The transmission cylinder 19 transmits power between the driven side of the first transmission case 17 and the drive side of the second transmission case 18, and the second cylinder 19c supports the middle part of the conveyance case 15. Although the second cylindrical body 19c supports the middle part of the transport case 15, the power is transferred to the rear end of the transport case 1 due to the interposition of the second transmission case 18.
5 is entered.

The present invention provides a means for transporting bundled waste straw and a means for changing its posture, and takes over the bundled waste straw from a straw tying machine attached to a combine harvester, transports it to a position at an appropriate height above the already cut field, and at the end of the transport, binds and removes the straw. Because it was made to fall and release into the mowed field in an almost vertical position,
The bundled waste straw discharged into the field from a combine harvester with a binding machine can be automatically arranged in a conical vertical position with the stock bottom facing down, making post-work such as collection easier.

Furthermore, the waste straw conveying means has its rear part supported by a support pipe extending toward the rear of the machine body, and its intermediate part supported by a transmission cylinder having an internal transmission shaft for transmitting power to the waste straw conveying means, Since the bundled and removed straw discharge device is installed at the rear of the combine harvester with a straw tying machine, the bundled and removed straw discharge device is supported by a support pipe and a transmission tube to simplify the support mechanism and to strengthen it with two-point support. Furthermore, since there is no support mechanism on the transport start side, the bundled waste straw will not be obstructed or caught by the support mechanism during transfer, and by allowing the disturbed grain culm to fall, the bundled waste straw can be tied to the transport means. It is possible to prevent the disorder of the bundled waste straw when handing over the waste straw, smooth the handover of the bundled waste straw, and more effectively make the bundled waste straw released into the field into a conical vertical position.
