Description

[Detailed description of the invention] [Industrial application field] The present invention binds threshed culms and transports the culms discharged from the binding machine in a pinched manner from the uncut land side to the harvested land side, which is further away from the uncut land side. It is related to the device.

[Background of the idea]

The object of this invention is to ensure that the bundled culms are conveyed in the correct posture to a device that discharges the bundled culms all at once or three-dimensionally discharges the bundled culms one bundle at a time in an upright state in a field.

In particular, when transporting waste culms discharged from a binding machine, if the positions of the transport clamps on the culm body of the bundled waste culms are different, the culms will be uneven when received by the culm collecting device, and adjustments will have to be made when collecting them. Furthermore, when discharging three-dimensionally, the discharge balance of the bundled culms is often disrupted and the culms are discharged sideways onto the field, which can impede the function of post-work, and the present invention can also prevent the above-mentioned problems. This is the purpose.

[Means for solving problems]

The structure of the present invention that solves the problems of the conventional technology is as follows:
A culm binding machine is provided at the rear of the machine, and a holding member (holding rod) is provided at the discharge part of this binding machine to receive the base side from the clamping part of the conveyor that pinches and conveys the tip of the bundled culm. In the bundling and culm conveying device, the clamping member 17 is made of an elastic body, the front end of the clamping member 17 is fixed to the binding machine, and the clamping member 17 is connected to the two binding machines constituting the binding machine. A bundled culm provided between the discharge arms 8 and 9 and along the discharge direction of the bundled culm, and further provided at the rear end of the holding member 17 to cross over the conveying body and along the conveyance direction thereof. It is characterized by extending above the receiver.

〔Example〕

The configuration of the present invention will be described with reference to the embodiment shown in the drawings. A culm binding machine B is provided at the rear of the combine harvester A and in the threshed culm discharge section.
The tying machine B includes a tucking car 4 that is located behind the culm scraping path 3 and rakes the culm, a sensing door 5 that senses the amount of culling that has been raked, and a binding string attached to the culm that has been raked a certain amount. It consists of a needle 6 for hanging the culm, a knot 7 for tying a knot on the binding string, and two discharge arms 8 and 9 for discharging the bound culm out of the machine. Reference numeral 11 is a shutter that rotates by the pressure of the culm when the culm is released.

C is a conveying body that conveys the bundled culm to a post-working mechanism such as the three-dimensional discharge mechanism D shown in the drawing;
The conveyor C is composed of an endless conveyor chain 12 and a clamping rail 13.
is vertically swingable via a spring 15 between it and the support stand 14.

16 is a receiver for receiving the root side of the bundled culm discharged from the binding machine B, and 17 is a holding rod formed of an elastic body that holds the base of the bundled culm between it and the receiver 16. This presser rod 17 is fixed to the binding arm 10 of the binding machine B with a screw so that it can be adjusted up and down. Although the receiver 16 is shown in a bar shape in the drawing, it may also be in a plate shape (table), and the length of the tip of the receiver 16 may vary depending on the type of post-work machine, such as extending to the terminal end of the carrier C. It should be adjusted accordingly.

The three-dimensional discharge mechanism D inherits the bundled culm conveyed by the bundled culm conveyor C, and this three-dimensional discharge mechanism D consists of a conveyor chain 19, a clamping rail 20, a root presser 21, and It is composed of a discharge guide 22, a discharge chute 23, and the like. 24 is a shoot guide, 25
is a chain cover.

[Explanation of action]

Next, to explain the operation of the present invention, the standing grain culms in the field are harvested in the pre-treatment section of combine A, and the threshed grain culms become waste culms and are transported from the waste culm discharge port of the threshing device. It is transported to the rear of the machine by devices 1 and 2, and is passed through the culm raking path 3 of binding machine B.
and is sequentially scraped into the sensing door 5 of the binding machine B by the packer 4. When a certain amount of waste culm is present, the sensing door is pushed, and the tying string is hung by the needle 6 which is in an interlocked state with this, and then a knot is tied to the tying string at the knot 7, and then The binding string on the needle 6 side is cut and the binding work is completed. When the culms are bundled, the bundled culms are ejected backward by the discharge arms 8 and 9, push down the shutter 11, and are ejected to the starting end of the bundled culm carrier C at the rear. .

The released bundled culm is fed into the starting end of the conveying chain 12 and the clamping rail 13 that constitute the bundled culm conveyor C, and at the same time, the base side of the bundled culm is transferred to the receiver 16 and the holding rod 17. As a result, the bundled culms are held in a pinched state, and the bundled culms are reliably fed into the conveyor C without being dislodged. When the clamped and conveyed bundled waste culm is transferred by a certain amount, the base of the waste culm is pulled from between the receiver 16 and the presser rod 17, and this force pushes the presser rod 17 upward. It is fried, and the root of the culm comes off and is sent to the terminal end of the carrier C and discharged. The presser rod 17 is adjusted to an appropriate pressure according to the size of the bundle of culms.

The bundled culms transported to the terminal end of the transport body C are transferred by a three-dimensional discharge mechanism D provided diagonally upward in the extended state of the transport body C. and,
While being transported, the bundled culm is forcibly pushed down with the root facing downward by a root presser 21 having an elastic action, and is conveyed to the end of the three-dimensional discharge mechanism D, and the bundled culm is removed by a discharge guide 22. A chute guide 24 formed on the side of the discharge chute 23 and substantially perpendicular to the ground.
Along the way, the bundled culms are released and allowed to fall with their roots facing downwards in a substantially perpendicular state to the field. The released bundled culms are left in a three-dimensional state in the field,
This work progresses. In addition, when discharging the bundled culms in fixed quantities to the mown field side, remove the three-dimensional discharge device D and install the conventionally used culm collection device below the terminal end of the bundled culm conveyor C. That's fine.

[Effect of idea]

As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) Separately from the conveyor that transports the bundled culms laterally, the bundled culms are delivered to the discharge section where the bundled culms are discharged by the discharge arm of the binding machine. Since a clamping member is provided that receives and clamps the middle part of the bundled culm in cooperation with the carrier, the root side of the bundled culm is securely held between the carrier and the receiver until the tip side of the bundled culm is clamped by the carrier. Even when the bundled culm is received by the culm and forcibly released by the release arm of the binding machine, the posture of the culm is not disturbed, and the carrier can always hold the culm at a predetermined position.

(b) Since it is possible to firmly hold the root side of a long grain culm, it is possible to prevent the bundled culm from slipping down toward the root side before the conveyor grips the tip side. Therefore, the correct posture can be released even during the subsequent three-dimensional release work.

(c) Since the holding member 17 is provided between the two discharge arms 8 and 9 and along the direction in which the bundled culm is released, the clamping member 17 is provided between the two discharge arms 8 and 9, so that the clamping member 17 is located between the two discharge arms 8 and 9. The upper part is held and the discharge of the bundled culms is not disturbed, and the bundled culms can be properly discharged and supplied to the conveyor.
