The pre-cutting device 3 configured as above is
As can be seen in FIG. 9, the cutting device is supported by a mowing elevating cylinder 31 which is extended and retracted by a hydraulic device, and is configured to move up and down between a lower normal working position and an upper non-working position. It has a configuration that can be used.

Next, the threshing apparatus 2 has a feed chain 5 as can be seen from the whole combine 4 in FIG. 11, and a handling chamber having a handling cylinder mounted on the upper side is disposed on the upper side as conventionally known. On the lower side, a sorting room equipped with a rocking sorting device and a pressurized karamin is installed, and the supplied harvested culms are threshed and sorted. The feed chain 5 is provided with a holding rod 11 along the upper side, and is configured to hold the spike of the grain stalk inserted into the handling chamber and convey it. In addition,
In the case of the embodiment shown in FIG. 7, the doughen 5 is supported by a feed chain open mechanism 13, and is pivoted outwardly from the body of the threshing apparatus 2 with the support shaft 32 as a pivot point to handle the compartment. And open to the sorting room.
Therefore, the threshing apparatus 2 having the above configuration is convenient because cleaning and maintenance of the handling room and the sorting room are easy.

Next, as shown in FIG. 1, the front succession chain 7 is provided just in front of the feed start end of the feed chain 5 so that the start end of the feed chain 5 is divided.
The grain stem inherited from the above-mentioned supply adjusting device 6 on the side of the pre-cutting device 3 is inherited by the following feed chain 5. As shown in FIG. 1, the auxiliary succession chain 8 is disposed inside the front succession chain 7 and the feed chain 5, and at the time of the front succession chain 7, the auxiliary succession chain 8 has the tip side of the grain culm. Is supported. As shown in FIG. 1, the front inheriting chain 7 has its transport start end located at a position forward (upward in the grain culm transport direction) from the transport start end of the auxiliary succession chain 8, and the terminal end is also as described above. The auxiliary transfer chain 8 is configured to be located on the front side with respect to the terminal end portion. In this case, the auxiliary inherited chain 8 assists the grain culm inheriting action between the terminal end of the front inherited chain 7 and the transport start end of the feed chain 5, and also has a very short culm (from the front inherited chain 7 to the front inherited chain 7). It has a structure that can inherit a short culm that is too small to reach.

As shown in FIG. 6, the transmission structure between the front succession chain 7 and the auxiliary succession chain 8 is changed from the transmission pulley 33, which is mounted on the rear part of the pre-cutting device 3, to the chain case 34. The auxiliary transmission chain 8 is transmitted through the auxiliary transmission chain shaft 35, and then the rotational power is transmitted to the front transmission chain 7.

As shown in FIGS. 4 and 5, the auxiliary succession chain 8 is provided with a flat guide extending to the left and right sides by continuously attaching an uphill surface 14a to the front side thereof along the conveying direction of the succession grain culm. Dustproof and grain stalk-inducing cover with surface 14b
14 surrounds it. In the case of the embodiment, as shown in FIG. 5, the dustproof and grain culm guiding cover 14 is provided on the inner side surface of the auxiliary succession chain 8 (on the ear side of the succession grain culm and opposite to the front succession chain 7). It is configured to be covered with the side plate 14c.
The guide surfaces 14b on both left and right sides of the auxiliary succession chain 8 are the chains 8
Is located below the bottom (valley) of the transport lug 8a.

As described above, the auxiliary succession chain 8 is surrounded by the dust-proofing and culm-guiding cover 14 so that the up-slope surface 14a, the guide surface 14b, and the side plate 14c function to eliminate the litter accumulation and remove the straw. Debris can be smoothly discharged to the rear, and there is an advantage that falling can be prevented from falling down and winding around the rotating portion can be prevented.

The front inherited chain 7 and the auxiliary inherited chain 8 move up and down in conjunction with the up-and-down rotation of the cutting pretreatment device 3 provided on the front side, so that the inheritance of the grain stalk is not impaired. However, this configuration will be described on another occasion. Next, as shown in FIG. 1 and FIG. 3, the grain stem guide rods 9 and 10 have their bases attached to the attachment members 36 of the cutting pre-processing device 3 on the front side, respectively, and extended rearward to form the auxiliary inheritance chains 8. It is provided along the upper side (the grain culm conveying surface) with the front inherited chain 7 and further extended to the side position of the holding rod 11 of the feed chain 5 behind. As shown in FIG. 1, the culm guide rods 9, 10 are located on both sides such that the two distal ends sandwich the holding rod 11, and are interlocking / regulating provided on both sides of the holding rod 11. It is configured to be able to transmit to the holding rod 11 a force that moves upward (when raised) against the member 12 from below.

The culm guide rods 9 and 10 are made of an elastic material, so that they can sufficiently adapt even when the positions of the front succession chain 7 and the auxiliary succession chain 8 change up and down. In addition, it is possible to accurately cope with changes in the layer thickness of inherited grain culm.

As shown in FIG. 3, one of the grain culm guide rods 9 is disposed at a position where the gap L is maintained from the upper end of the transport lug 7a of the front succession chain 7 when there is no grain for transport. It is composed. And this stalk guide rod 9
1 and 3, as shown in FIGS. 1 and 3, the front end side can be kept engaged with the feed chain 5 at the rear in a state where there is no transported grain culm. Therefore, when the feed chain 5 is rotated by the feed chain open mechanism 13 as shown in FIG. There is a feature that it smoothly rotates (see the phantom line in FIG. 8) without contact or interference such as being scratched by 7a.

As described above, the cereal stem guide rod 9 is designed so as not to be an obstacle even if it is on the rotation direction side (front side) when the feed chain 5 is opened. As described above, the feed chain 5 of the threshing device 2 is, as shown in FIGS. 3 and 12, between the feed adjusting device 6 of the pre-cutting device 3 and the front inherited chain 7 and the auxiliary inherited chain 8. Although the length is shorter than the conventional chain length, the transport function at the time of threshing can be sufficiently performed. As described above, since the feed chain 5 was shortened, the tension chain constituted by the plate spring 37 could be replaced with a chain tensioner instead of the tension sprocket conventionally provided inside the intermediate portion. Therefore, as shown in FIG. 12, the support structure of the feed chain 5 has a feature that it can be manufactured at low cost and compactly as compared with the conventional structure.

Next, the operation will be described. First,
Starting the engine, engaging the mowing clutch and threshing clutch to transmit the rotating parts of the body,
To start cutting and threshing work by the combine 4. Then, as shown in FIG. 9, the culm in the field is subjected to weeding by the weeding rod 19 at the lower front end, and is then caused to rise from the lying state to the upright state by the raising action of the cereal stem raising device 20. When the stock reaches the reaper 18 and is harvested, it is raked by the action of the scraping wheel 24a and the endless band 24b, and the stock carrier 21 and the tip carrier 2
2 and sequentially conveyed upward continuously at the rear.

In this way, as shown in FIG. 10, the cereal culm is composed of a large number of rows collected and the left and right conveying devices 21 and 2,
2 and are merged at the rear, and the handling depth adjusting device 2
3 and successively transferred to the feed control device 6 in a continuous state, reaches the start end of the front transfer chain 7, and also receives the action of the auxiliary transfer chain 8, reaches the start end of the feed chain 5 and threshing device 2
Supplied to

As for the grain culm, the origin of the culm is fidochene 5
While being conveyed while being held by the holding rod 11, the tip portion is threshed by the rotating handling cylinder in the process of being inserted into the handling chamber and passing therethrough. And the threshing processed product,
It reaches the lower sorting room and is subjected to the sorting wind by the action of the sorting wind and the swing sorting device.

As described above, the combine continuously performs harvesting and threshing work, harvests the selected threshed grains, and collects and stores them in the Glen tank. During such a continuous operation, the cereal stalk guides 9 and 10 convey and supply the inherited cereal culm to the feed chain 5 while sandwiching the inherited culm between the front inherited chain 7 and the auxiliary inherited chain 8. At this time, the stalk guides 9, 10 are pushed upward by the layer thickness of the stalks to be conveyed, and the tip ends thereof are provided on both sides of the holding rod 11 as shown by the imaginary line in FIG. The interlocking / restricting member 12 is brought into contact with and pushed up from below. Therefore, the holding rod 11 is lifted at the start end, receives the succeeding grain culm supplied from the front side into a smooth state, holds it in the state of being sandwiched by the receiving feed chain 5, and conveys it backward as described above.

As described above, the grain stalk guides 9, 10 are regulated by the interlocking / regulating member 12 (clamping rod 11), while transmitting the pushing force to the clamping rod 11 as described above, and moving the guide itself abnormally upward. In addition, the grain can be held between the two inherited chains 7 and 8 at an appropriate pressure, and the conveyance can be continued. At this time, since the holding rod 11 receives the pushing force received from the culm guides 9 and 10 via the interlocking / regulating member 12 from both sides, the phenomenon of “twisting” and “koze” of the holding rod 11 itself almost occurs. It can rise smoothly without doing so.

In such a conveying process, the auxiliary succession chain 8 is surrounded by the dustproof and grain culm guiding cover 14 having the front uphill surface 14a, the left and right guide surfaces 14b, and the inner side plate 14c. It is possible to eliminate the accumulation of the straw waste and smoothly discharge the straw waste backward. Moreover,
The dust-proof and culm-inducing cover 14 can also prevent the waste from dropping to the lower rotating part, thereby eliminating the winding and eliminating the conventional defect.

Then, after the work is completed, when cleaning and maintenance of the handling room and the sorting room, the feed chain 5 is rotated outward with the support shaft 32 of the feed chain open mechanism 13 as a rotation fulcrum. Feed chain open. At this time, the grain stalk guide 9 is disposed at a position where the gap L is maintained from the upper end of the transport lug 7a of the front succession chain 7 in a state where there is no grain transported. Instead, it can be integrally rotated to the position of the virtual line shown in FIG.

As described above, according to the present invention, as described in the specific embodiments, the starting end of the holding rod 11 of the feed chain 5 is utilized by using the grain stalk guides 9 and 10 pushed up by the inherited grain stalk. Is lifted upward from both sides in synchronization with the supply timing of the grain culm, so that the action of passing the grain culm to the feed chain 5 can be performed smoothly. The cereal stem guides 9 and 10 are provided so that the bases are fixed to the pre-cutting device and the leading ends are extended so as to extend over the feed chain 5, so that the culms can be smoothly transferred. However, in particular, since the stalk guide 9 on the rotating side can be integrally rotated when the feed chain is open, there is a feature that a smooth feed chain can be performed without any obstacle.

The auxiliary succession chain, which is effective for the succession and supply of the ultrashort culm from the supply adjusting device of the pre-cutting device to the beginning of the feed chain, is particularly useful for collecting straw waste. It has the characteristic that the culm can be smoothly guided to the feed chain by preventing wrapping around the rotating parts.
