Description

[Detailed description of the invention] This invention is equipped with a binding device on the rear side of the body of the threshing device for a combine harvester that accepts and binds the removed culm after threshing in a sideways position, and the removed culm after binding is attached to the machine. It is an object of the present invention to provide a bundled culm discharge device for accurately discharging to a predetermined location on the rear side.

Conventionally, when the forced release arm that acts on the stock side of the culm releases the culm after binding, contact resistance is applied to the tip side of the culm to release the culm. It adopted a rotating release means centered on the
According to this, a certain degree of direction change could be expected, but since the active part of the forced ejection arm is the heavy stock side, the light tip side part is moved away from the contact resistor part by the ejection force from the stock side. The plucking will come off immediately, and it will not receive sufficient swirling release action centered on the tip of the head. - It will be thrown away with force in the direction of the release action of the forced release arm, and it will be scattered towards the uncut land.
There was a defect in the product that was often released and caused problems in the next process.

Therefore, by equipping such a device with a special discharge device, that is, a discharge device that inherits the stock side of the culm discharged by the forced discharge arm and carries it out rearward while bringing it closer to the tip side of the culm. In this case, the discharge device is composed of a discharge belt and a discharge guide rod, and the width of the vertical interval of the discharge passage formed between the two is If the structure is equal to or larger than that of the bundling passage, the culms released by the forced release arm will not be able to be stopped on the release belt in an appropriate posture, and the culms will have too much momentum to climb over the release belt. There was an inconvenience that it would fall off and be released onto the uncut land.

In order to eliminate this inconvenience, the present invention configures the vertical interval width of the discharge passage to be narrower than that of the bundling passage, so that the culm that is forcefully discharged by the forced discharge arm can be moved into the narrow space. The discharge belt and the discharge guide rod, which rotate at high speed, are used to temporarily catch the culm at the starting end of the discharge passage to prevent it from falling off, and to hold it in an appropriate position. It has now become possible to carry out the removal process with great force while reliably bringing it to one side of the mowed field.

This invention will be explained in detail below based on an embodiment shown in the figure. 1 is a combine harvester, a pair of left and right traveling devices 2,
A reaping section 4 is provided at the front of the machine body 3, which is equipped with a reaping section 2'.
A threshing device 6 equipped with a foot chain 5 extending substantially parallel to the traveling direction of the machine body 3 is mounted on the rear of the machine body 3.

Behind the threshing device 6, the culm after threshing is placed on its side.
A culm binding device 7 for receiving and tying the culms is installed, and a knotting section 9 consisting of a building, a holder, etc. is placed on the upper side of the tying path 8 that follows the culm conveyance path after threshing, and a knotting section 9 for supplying strings is placed on the lower side. The needles 10 are provided to face each other, and the lower needle 10
The side is equipped with a focusing rod 11 and a packer 12, and the upper node 9 side is provided with a tube that spans both left and right sides of the focusing rod 11 and extends from the front of the culm receiving side to the rear position of the receiving rod 11. A forced release arm 13 having a range A between the release operation loci is provided.

Reference numeral 14 denotes a transmission case which is a component of the binding device, and houses a transmission mechanism for transmitting rotational power to each part of the binding device, and this transmission case 14 is located on the tip side of the ejected culm. In this state, the converging rod 11 is connected and held by the support member on the knot portion 9 side and the support member on the needle 10 side, and is moved along the binding path 8.
It is configured as a contacting body that provides resistance by coming into contact with the tip side of the culm that is received by the culm.

Reference numeral 15 denotes a discharge belt that takes over the stock side of the bundled culm discharged by the discharge arm 13 and carries it out rearward, the starting end of which looks below the terminal end of the bundle passage 8, and which is connected to the discharge arm 13. It is located closer to the plant base than the release action position, and is arranged in an inclined manner in plan view so that the terminal end thereof is gradually shifted toward the tip of the culm.

In addition, this discharge belt 15 is hung on a pair of front and rear pulleys supported by a support frame 16 which also serves as a cover, and its starting end is covered with a cover 17 and is tilted so as to easily receive the culm. A downwardly inclined receiving surface 18 is formed, and a receiving plate 19 extending from the inside of the receiving surface 18 is provided to prevent the culm from falling downward when the culm is a short culm.

Further, the discharge belt is supported by a support pipe 21 that extends diagonally backward from the binding machine frame 20 below the binding passage 8 and is equipped with a power transmission shaft. Interlocking and connecting via
It is constructed so that a circumferential speed comparable to the operating speed of the packer 12 (the circumferential speed may be approximately the same as the operating speed of the discharge arm 13) is obtained.

Reference numeral 22 denotes a discharge guide rod provided along the upper side of the discharge belt 15, and the starting end thereof is bent upward to form the binding passage 8.
It is mounted and supported on the upper binding machine frame 23.

The interval width 12 of the discharge passage 24 formed between the discharge guide rod 22 and the discharge belt 15 is configured to be narrower than the interval width 11 at the end of the binding passage 8.

Since the present invention is configured as described above, the husk harvested by the reaping section 4 and supplied to the threshing device 6 is held and transferred by the foot chain 5, threshed by the threshing device 6, and sent out from the discharge port.

The waste culm after threshing is fed into the binding device 7 while being transported along the waste culm transport route.

In this bundling device 7, the culm received in the bundling passage 8 is compressed by the packer 12 toward the collecting rod 11 side.

When the amount of discharged culm reaches a certain amount, the focusing rod 11 is activated by the compressive force, and the needle 10 and knot part 9 are activated to bind the discharged culm. As a result, the focusing rod 11 is pushed open to the position shown by the imaginary line and released to the rear of the aircraft. , The stock end side is rotated and released from the above-mentioned state position A to the mouth state position centering on this tip side, and is sandwiched at the starting end of the discharge passage 24 formed by the discharge bell I 15 and the discharge guide rod 22. Under this condition, the ejecting culm is in an attitude almost perpendicular to the ejection belt 15 as shown by the opening above, and from then on, it rotates at high speed with the ejection guide rod 22. The discharging bell I-15 quickly pulls the culm towards the tip and forcibly carries it out, but at this mid-transfer position, the tip detaches from the abutting body 14, and the stock end swings around a lot. It is then dropped from its end into a field, changed direction and left as it is.

As shown in the embodiments above, according to the present invention, the culm discharged from the threshing device in the horizontal position is received with the knot 9 placed on the upper side and the knot 9 on the lower side with the binding passage in between. A combine harvester is equipped with a tying device in which string supply needles are arranged opposite to each other, and the tying device includes a forced release arm that acts on and releases the culm base side after tying, and a forced release arm that releases the culm at the time of release. and a contacting body that provides resistance by contacting the tip side of the culm, and further includes a contacting body that applies resistance to the tip side of the culm, and further includes a contacting body that continuously connects to the end of the bundling passage and inherits the stock side of the culm that is released by the forced release arm and provides a rear part of the culm. A culm discharging device consisting of a discharging belt and a discharging guide rod for forcibly discharging the culm is configured to extend in an inclined manner in plan view so that the terminal end side is biased toward the tip side of the culm, and the culm inheritance of the culm discharging device is The area is formed into a wide space A that is wide in the vertical direction, and the interval width 12 of the discharge passage 24 constituted by the discharge belt 15 and the discharge guide rod 22 is made to correspond to the upper and lower interval width 11 of the binding passage. Since the configuration is narrower than that of the bundling passage, the wide space A formed at the culm receiving part of the culm discharge device creates a volume when the culm is turned around and released from the tip side. Since the plant side receives no (little) resistance, this turning and releasing action of the culm can be performed smoothly without greatly disturbing the posture.

Moreover, during release, when the culm stops momentarily due to resistance from the tip side of the culm or the abutting body, the culm turns and assumes a tilted position. Even if the culm shifts toward the body and tries to fall, it is possible to prevent the culm from falling by restricting the base side of the culm with a narrow discharge passage. As soon as the receiver is put into the passage, it is forcibly discharged by the discharge belt, and while the unbound culm converged in the binding passage and the discharged bundled culm are well separated, the discharge from the wide space is prevented. The base side of the culm can be quickly carried out to the rear to eliminate falling and stagnation of the culm in the wide space, and as a result, the discharge culm comes into contact with the discharge culm that is stagnant in the wide space. or prevent the releasing action from being obstructed by the above-mentioned wide space, or ensure that the guiding action of the voluminous culm root side is performed by the above-mentioned wide space part, and the culm tip side of the bundled culm is centered. This allows the swirling and discharging action to be performed even more effectively.
