Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a tying machine that is attached to the waste straw delivery section of a combine harvester and is used to bind the waste straw that is sent out and then discharge it outside the machine.

BACKGROUND TECHNOLOGY In the above-mentioned tying machine, the knotting part of the tying machine is
In the case where it is located below the straw removal passage,
In some cases, it is located above the passage.

In other words, if the knot is installed so that it is located at the bottom of the binding path and the convergence part is located above, the discharge arm provided in the knot will be directed downward in the operating direction and the discharge distance will be shortened. The power required for discharge is low and the bundle does not collapse, and the pucker installed in the collecting section operates in a downward direction and presses the straw against the straw transport plate while raking it, ensuring reliable raking and transport. Therefore, the knots are generally placed on the lower side, but if it is better to release the waste bundles from a higher position, for example, when the bundles are placed on the bottom side of the field. In the case of dispensing, it is best to place the converging part at the bottom of the passage and the knot part at the top of the passage, so that the operating locus of the discharge arm provided at the knot part is directed upward, so that the discharge action distance can be increased. This is advantageous because it can be held upward for a long time.

By the way, in a binding machine, a constantly operating packer is arranged in the converging section, so the constantly rotating shaft that drives the packer is used as an input shaft, and the power from the drive source is input to this input shaft so that the power is transmitted. Therefore, the same tying machine cannot be used in common with the knot part located below the bundling passage and the knot part located above the bundling passage, and it is not possible to use the same tying machine in a state in which the knot part is located below the bundling passage and in a state in which the knot part is located above the tying passage. It is configured as a.

Problems to be Solved by the Invention The present invention eliminates the need to configure a binding machine in which the knotting part is located above the binding passageway and a binding machine in which the knotting part is located below the binding passageway in the same way. The purpose is to obtain a binding machine transmission device that can be used in two ways as needed using a binding machine, and furthermore, the transmission structure is compact while being able to be used in two ways. It is something we try to obtain.

Means for Solving the Problems In other words, the present invention provides a bundler 1 on the bundler A side of the bundler A and the knot part B, which are disposed on one side of the transmission case 10 and are opposite to each other across the binding passage. A constantly rotating input shaft 11 that drives the needle 2, an intermittent drive shaft 12 that is interlocked with the input shaft via a one-turn clutch 14 and drives the needle 2, and a door shaft 8 that controls the operation of the one-turn clutch 14 are arranged. On the part B side,
In the combining machine for a combine harvester, which is configured by providing a joint drive shaft 9 which is interlocked and connected to the intermittent drive shaft 12 and operates the building 5, the discharge arm 4, etc., the input shaft 11 on the side of the converging section A is connected to the transmission case 10. The second input shaft 24 is provided so that it can be linked to the drive source from the back side of the transmission case 10, and another second input shaft 24 that can be linked to the drive source from the back side of the transmission case 10 is also installed on the node B side. The first feature is that the input shaft 11 and the input shaft 11 are connected to each other so as to be constantly rotated, and the entire structure can be turned up and down and reversed to be used by attaching it to a combine harvester.
A second feature is that the intermittent drive shaft 12 and the second input shaft 24 are interlocked and connected via the constantly rotating shaft cylinder 13 of the one-turn clutch 14 incorporated in the intermittent drive shaft 12.

Effect This invention, by taking the above-mentioned solution,
By moving the entire binding machine up and down, turning it inside out and mounting it on the machine body, and interlockingly connecting the drive source to the input shaft or second input shaft, a single binding machine can position its knotted part upward. It will be used in a state where it is located below.

Furthermore, if the input shaft and the second input shaft are interlocked via the constantly rotating shaft cylinder of the one-turn clutch in the intermittent drive shaft, parts of the transmission structure can be shared and the interlocking structure can be improved. This makes it simple, and the second input shaft can be installed close to the nodal shaft and the intermittent drive shaft interlocking part, making the whole structure compact.

implementation row The embodiments shown in the drawings will be described below.

Similar to the conventional tying machine, the converging section A includes a packer 1, a needle 2, a door 3, etc., and the knotting section B includes a discharge arm 4, a billet 5, etc.

A packer shaft 6 for driving the packer 1 is integrated with an input shaft 11 and constantly rotates, and the input shaft 11 receives input from the rear side of the transmission case 10. The needle drive shaft 7 is integrated with the intermittent drive shaft 12 and rotates intermittently. The door shaft 8 rotates when the pressing force of the bundled waste against the door 3 exceeds a predetermined value, and freely connects and disconnects the shaft cylinder 13 loosely fitted to the intermittent drive shaft 12 and the intermittent drive shaft 12. A one-turn clutch (one-way clutch) 14 is connected to the intermittent drive shaft 12 for transmission.
The one-turn clutch 14 is placed in a "contact" state by the rotation of the door shaft 8. The shaft cylinder 13 is constantly transmitted to the input shaft 11 via the passive gear 15 and the input gear 16 of the input shaft 11, and is constantly rotated. The end of the knot shaft 9 for intermittently driving the knot portion B is protruded into the transmission case 10, and the driven sprocket 17 is fixed to form the intermittent drive shaft 1 of the converging portion A.
2, and a chain 19 is wound around both sprockets 17 and 18 to constantly transmit power between the intermittent drive shaft 12 and the joint shaft 9. When the intermittent drive shaft 12 rotates intermittently under the control of the door shaft 8, the joint is connected. Axis 9
is also configured to rotate intermittently at the same time.

The transmission case 10 includes bearings 20, 20', 21, 2
1' rotatably supports the input shaft 11 and the intermittent drive shaft 12, and bearings 22, 22' are also provided on the node B side to rotatably support the second input shaft 24. Enable input. Further, the second passive sprocket 23 is integrally formed with the shaft cylinder 13 which is constantly rotating.

When the second input shaft 24 is installed, as shown in FIG. 1, the second passive sprocket 23 is
A second input sprocket 25 that is integrally fixed to the second input shaft 24 and a sprocket shaft that constantly rotates regardless of whether power is input from the input shaft 11 or the second input shaft 24 through the chain 26. 6 and the shaft cylinder 13 can be driven at all times.

For models that do not require the second input shaft 24,
As shown in FIG. 2, the chain 26 and second input sprocket 25 are omitted, and the end is connected to the transmission case 1.
Install the shaft 24A that does not protrude beyond 0 to prevent leakage of gear oil. Also, rubber cap 2 can be added as desired.
7 may be mounted outside the bearing 22.

In the case of a model that does not require the input shaft 11, when assembling the binding machine, the input end 11A that protrudes outward from the transmission case 10 is removed in the same way as the shaft 24A used when the second input shaft 24 is not used. input shaft 1
1 may be used.

Figure 3 shows the binding machine of the present invention located at the rear and left side of the combine body, and the transmission case 10 is vertically positioned with the focusing part A [packer 1 etc.] on the upper side and the knotting part B [discharge arm 4] on the lower side. This shows the case where it is installed in this position.

In a system in which the converging part A is at the bottom and the knotting part B is at the top, the bundling PTO shaft of the combine main body 28 is set so that the input shaft of the bundling machine, the transmission belt, etc. are placed below the transport path so as not to cause problems in transporting the shucked straw. 30 is located below the feed chain 29, but near the position of the input shaft 11 in the above conventional system,
A binding machine is attached to the combine harvester by positioning the second input shaft 24, and power is taken into the second input shaft 24 from the binding PTO shaft 30 via a drive pulley 31, a belt 32, and a driven pulley 33.

In short, when assembling the binding machine of the present invention,
The selection of the second input shaft 24 and the shaft 24A is arbitrary.
This will be determined at the time of assembly depending on the type of combine harvester to be installed, the mounting position and orientation of the binding machine, but if the versatility of the binding machine is important, the chain 26 gear 2
5, the product is a binding machine in which power can be input freely from both the input shaft 11 and the second input shaft 24,
When attaching a binding machine to a combine harvester, the two input shafts 11 and 24 are used as input shafts, as appropriate.
You may choose.

Effects of the Invention As described above, in the present invention, the pack car 1 is driven to the convergence part A side of the convergence part A and the knot part B, which are disposed on one side of the transmission case 10 and opposite to each other across the binding passage. A constantly rotating input shaft 11, a one-turn clutch 14 on the input shaft
An intermittent drive shaft 12 that drives the needle 2 and a door shaft 8 that controls the operation of the one-turn clutch 14 are provided on the joint B side. 5. In a combining machine attached to a combine, which is configured with a knot drive shaft 9 that operates the discharge arm 4, etc., the input shaft 11 on the focusing section A side can be linked to a drive source from the back side of the transmission case 10. At the same time, another second input shaft 2 is provided on the node B side, which can be linked to the drive source on the back side of the transmission case 10.
4 is installed, and the second input shaft 24 and the input shaft 11 are connected to each other in constant rotation,
Since the entire unit can be turned upside down and reversed to attach it to the combine harvester, the input shaft on the focusing side and the second input shaft on the knotting side can be selected as desired, and the binding machine PTO shaft (drive source ), it is possible to convert a single binding machine into a state in which the knot is located above the binding path and a state in which it is located below the binding path, increasing the versatility of the binding machine. It is expensive and can be used conveniently.

In addition, in the case of the transmission device having the above structure, in which the input shaft and the second input shaft are interlocked and connected via the constantly rotating shaft cylinder of the one-turn clutch, it is compared to a transmission device in which the two shafts are directly interlocked. This allows some transmission parts to be shared, simplifying the transmission structure, and even if the second input shaft is installed closer to the intermittent drive side than the nodal shaft, the connection between the nodal shaft and the intermittent drive shaft is Since there is no problem with the interlocking structure, there is an advantage that the entire transmission case can be made compact without increasing the size of the transmission case.
