Description

[Detailed description of the invention] The present invention repositions the waste straw processing device, which processes waste straw carried out from a threshing device that handles and threshes stem culms while holding and transporting them, in a horizontally suspended position, in the length direction of the waste straw culm. The present invention relates to a support structure for a waste straw processing device that is fixedly supported.

As mentioned above, the purpose of changing the position of the waste straw processing device in the length direction of the waste straw culm is to always maintain the desired positional relationship between the waste straw and the waste straw processing device, regardless of the length of the waste straw carried out from the threshing device. This is because it can be set to

In other words, in a normal threshing device, the length of the tip side of the stem culm inserted into the threshing device is maintained constant by adjusting the handling depth, and the length of the tip of the stem culm inserted into the threshing device is maintained constant. However, the relative positional relationship between the base end of the waste straw stock and the waste straw processing device changes depending on the length of the waste straw.

For this reason, for example, if a waste straw binding device as a waste straw processing device is installed in a fixed position, the Q binding position will change depending on the length of the waste straw, but as described above, the position will change in the length direction of the waste straw culm. This has the advantage that the waste straw can be tied at a desired position regardless of the length of the culm, and can be tied in a good condition with no strings coming off.

Furthermore, as a technique for supporting the waste straw processing device so that its position can be changed in the direction of the waste straw culm length, for example, there is a technique disclosed in Japanese Utility Model Application Publication No. 51-20962.
There are ideas disclosed in Japanese Utility Model Publication No. 50-27033.

In this system, a waste straw binding device or a straw cutter serving as a waste straw processing device is slidably supported on a machine body, and the position of the processing device is changed by the feeding function of a screw shaft.

However, in each of these conventional structures, the position of the waste straw processing device is changed using a screw shaft. It is difficult to change the position quickly depending on the length of the culm, and a screw structure with relatively high precision is required to ensure smooth position change operation. The load of the waste straw processing apparatus cannot be borne by the shaft itself, and a separate construction structure for supporting the load is required, resulting in the complexity of the overall structure.

In view of the actual situation of waste straw processing equipment such as the snow-covered situation, the present invention has been developed to support the waste straw processing equipment so that its position can be changed in the direction of the waste straw culm length. In addition, it is an object of the present invention to provide a support structure for a waste straw processing device that can firmly support the waste straw processing device.

Embodiments of the present invention will be described in detail below based on the drawings.

In the following embodiments, the waste straw processing device 6 is a waste straw binding device, and the long support rod 11a along the length direction of the waste straw culm is a horizontal rod pipe, and the guide 10 that supports the horizontal rod pipe is used. 10 is an example of a guide roller, and the rotating shaft 15 is a rotating cylinder shaft, respectively, in the description.

In the figure, the front part of the machine is equipped with a reaping section consisting of a pulling device 1, a reaping device 2, etc., and the stem culms pulled up and cut by this reaping section are transported vertically toward the rear of the machine by a vertical transport device 3. A combine harvester is shown in which the stem culms delivered from the vertical conveying device 3 are pinched and conveyed for threshing by a feed chain 5 installed on the lateral side of the threshing device 4 mounted on the rear of the machine. At the rear of the thresher 4, a waste straw binding device 6 is connected and equipped to process the waste straw discharged from the rear of the threshing device 4 in a horizontal position after threshing processing, also in a horizontal position.

As shown in FIGS. 2 and 3, in this waste straw binding device 6, a transmission case 6a is located at a lateral side portion close to the feed chain 5, and a lateral side portion away from the transmission case 6a. It is configured in a U-shape in rear view with a string supply section 6b and a knot section 6c located above and below the feed chain 5, and the waste straw discharged from the end of the feed chain 5 is connected to the guide cover 7a1 (described later). Rod 12 and guide rod 7
While being placed on the string b..., the tip side and stock side are locked and conveyed by a pair of left and right locking and conveying devices 8°8 until it is placed in a horizontal position between the string supply section 6b and the knot section 6c. After converging an appropriate amount, the cord supply section 6b and the knot section 6c work together to bind the cord in sequence.
It is configured to release the tied stem culm backwards.

Further, this binding device 6 is connected and supported by a fixed frame 9 that is detachably fixed to the rear portion of the threshing device 4, and its support structure will be explained below.

That is, as shown in FIG. 4, in the intermediate portions of the frame portions 9a, 9a extending diagonally upward and rearward within the fixed frame 9,
Guide rollers 1010 are connected and supported at large intervals in the lateral direction (see FIG. 6), and these guide rollers io, i
At o, a horizontal rod pipe 11a connected and supported by the tips of the connecting pipes ii, ii fixed to the lower end of the binding device 6 is received and supported so as to be movable laterally.

Further, a cylindrical frame 9b is connected and supported at the tips of the frame portions 9a, 9a, and the tip cylindrical portion 12 of the connecting rod 12, which also serves as the straw removal guide rod described above, is attached to the cylindrical frame 9b.
a is externally connected so as to be slidable in the lateral direction (see Fig. 5),
Moreover, one end of the connecting rod 12 is connected to the connecting pipe 11 and further connected to the binding device 6.

The binding device 6 is connected to the fixed frame 9 via a connecting pipe 11 and a connecting rod 12, and is configured to be able to change its position in the length direction of the waste straw culm, and
The horizontal rod pipe 11a is fixed at a required position by being fixedly supported by a clamp fitting 13.13 (see FIG. 6).

The binding device 6 is driven by the power transmitted from the threshing device 4, and its power transmission structure will be described below.

That is, a rotating cylindrical shaft 15 is rotatably fitted and supported in the cylindrical frame 9b of the fixed frame 9 via needle bearings 14, 14, and a pulley fixed to one end of this cylindrical shaft 15 is supported. Power from the threshing device 4 is transmitted to 16 by a belt.

A transmission shaft 17 is spline connected to the inside of the rotary cylinder shaft 15 so as to be movable laterally, and this transmission shaft 17 is supported internally by a bearing on the cylindrical portion "12a" of the connection rod 12. A pulley 18 fixed to one end of the transmission shaft 17 and an input pulley 19 pivotally supported by the transmission case 6a of the binding device 6 are interlocked and connected via a transmission belt 20.

Therefore, the power from the threshing device 4 is from the pulley 16 → the rotary cylinder shaft 15 → the transmission shaft 17 → the pulley 18 → the transmission belt 20 →
It is sequentially transmitted to the input coupler 19 and the binding device 6
The power is transmitted through the spline compatibility between the rotary cylinder shaft 15 and the transmission shaft 17, regardless of the position of the binding device 6.

In addition, in order to support the waste straw binding device 6 as in the embodiment, the seventh
As shown in the figure, a frame portion 9as9b of the fixed frame 9
is pivotally connected to the main body side around the horizontal axis X, and by interposing a telescopic connector 21° 21 between the threshing device 4 and the frame portions 9a, 9a with a turnbuckle mechanism, the removal can be achieved. The connecting posture of the straw binding device 6 with respect to the threshing device 4 can be changed and adjusted, and by this adjustment, the interval between the guide cover 1a and the locking conveyance devices 8, 8 can be adjusted to achieve the smoothest conveyance of removed straw. This provides the advantage of being able to set the device to a state in which it can be used.

The waste straw processing device 6 can also be applied to a waste straw shredding device that folds waste straw in half and shreds it.

In addition, similarly to the present invention, a fixed frame 9 on the side of the threshing device is used to support the waste straw processing device 6 so that its position can be changed in the length direction of the waste straw culm.
A support frame along the length direction of the waste straw culm is connected to the support frame, and the waste straw processing device 6 is supported movably in the length direction of the frame at a plurality of locations spaced apart from each other in the length direction of the frame. However, since the waste straw processing device 6 is equipped with a long support rod 11a along the length direction of the waste straw culm, the support rod 11a is attached to the waste straw processing device 6.
There are advantages to having a reinforced frame.

In summary, the structural features of the support structure of the waste straw processing apparatus according to the present invention are that a long support rod extending along the culm length direction of the waste straw is fixed to the waste straw processing apparatus through a connecting pipe, and The fixed frame on the side includes a guide that supports the supporting rod movably only in the length direction at a plurality of locations spaced apart from each other in the longitudinal direction of the supporting rod, and the supporting rod is moved toward the fixed frame side. For tightening, a clamp fitting is provided for fixing, and the structure for transmitting the driving force to the waste straw processing device is provided by a transmission shaft and a rotating shaft that are connected to each other so as to be movable relative to each other in an axial direction parallel to the axis of the support rod. and furthermore,
A rotary shaft located on the main machine side is supported and fitted in a cylindrical part connected and supported by the fixed frame so as to be freely rotatable only relative to the same, and the rotary shaft is fitted on the cylindrical part connected and supported by the fixed frame. A transmission shaft is fixed to the waste straw processing device and supported internally so as to be freely rotatable only relative to a cylindrical portion that is connected and supported via a connecting rod connected to the connecting pipe, and These two cylindrical parts are fitted and connected so as to be relatively movable in the axial direction.

Therefore, the support rod, which is connected to the waste straw processing device via a connecting pipe, is supported by a fixed frame at multiple points spaced apart from each other in the length direction, and a transmission shaft separate from the support rod is attached. At the same time, a cylindrical part connected to the waste straw processing device through a connecting rod is externally supported on the transmission shaft, and at the same time, a cylindrical part connected to the fixed frame is externally supported on the rotating shaft. Since it plays a role as a member, by supporting it at dog-like intervals and distributing the load of the waste straw processing device to three places: the support rod and the transmission shaft, Each support structure itself can firmly support the waste straw processing device in a desired posture without having to have a special strength structure, and in particular, the support members that support the waste straw processing device at the three locations are suitable for supporting the waste straw processing device. On the side, the support rod and the cylindrical part are integrated through the connecting pipe and the connecting rod, and on the machine side, the guide and clamp fittings that support the support rod movably in the length direction are connected to the cylindrical part through the fixed frame. Since the support structure is integrated with the parts, the support structure becomes a rigid body as a whole, and can be supported even more firmly, and the position of the waste straw processing apparatus can be changed and adjusted easily with less sliding resistance.

Furthermore, as mentioned above, the support at the three locations of the support rod and the transmission shaft is supported by a rigid structure. This is advantageous in terms of manufacturing, since it is possible to adjust the position of the waste straw processing device with light force without twisting, while suppressing the looseness caused by the flexibility of the support members and compensating for the decline in the guiding function. As mentioned above, one of them also serves as the structure for transmitting power to the waste straw processing equipment, so the structure of the entire waste straw processing equipment including this support structure is also lightweight and compact, making the overall This has the advantage that it can provide a support structure for a waste straw processing device that is extremely useful.
