Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention mainly relates to a grain culm conveying device in a multi-row cutting combine having 5 or more rows.

[0002]

[Prior Art]

 In a multi-row combine, the harvested grain culm is pulled up in the opposite direction from the left and right sides of the cutting width in the opposite direction at the rear of the machine and merged, and then passed on to the lifting and conveying apparatus. It has already been known from, for example, Japanese Patent Application Laid-Open No. 62-30522 (a), Japanese Utility Model Application Laid-Open No. 2-34125 (b), Japanese Patent Laid-Open No. 3-58710 (c), and the like.

[Problems to be solved by the device]

 However, in the conventional example as described above, the confluent grain culms are merged by advancing in opposite directions from the left and right sides of the cutting width (particularly the above a and b), so that the confluence part is formed. However, there is a drawback in that the transfer forces of the two directions influence each other and disturb the transfer posture of the grain culvert, so that the transfer to the lifting transfer device side cannot be performed properly. Also, in order to reduce the adverse effects of the left and right conveyance forces, the left and right conveyance bodies are arranged in an inverted C shape in plan view toward the middle part of the cutting width (b), and the conveyance length in the front-rear direction is Not only is the length increased, but it is inconvenient because the inverted C-shaped carrier constricts the installation space for the driver's seat that is desired to be installed as close to the device as possible to ensure a good front view. Furthermore, the one that merges the left and right conveyed grain culms in an orthogonal state (c type) has the same drawbacks as the above-mentioned a type, and has an adverse effect on the grain culm at the conveying confluence part (it is caught by the raising claw). There is a risk of being spilled or interfering with each other.

[0004]

[Means for Solving the Problems]

 The combine grain culm transporting device according to the present invention is made based on the above-mentioned actual condition, and the harvested grain culm is raised and made to join in the opposite direction from the left and right sides of the cutting width behind the device. Then, in the multiple-row cutting combine that is inherited by the lifting and conveying device, a majority of the total number of cuttings, the cut culms, are fed laterally from the side of the cut land to the direction of the uncut land. A main carrier having a horizontal transport section and a vertical transport section for transporting from the terminal end of the horizontal transport section to the lifting transport apparatus side, and the transport working side having a substantially L-shape in plan view is provided. A sub-carrier for sending the remaining number of cut culms to the direction of the already-cut land is provided on the side, and the corns on the side of the sub-carrier are transferred to the corn on the side of the main carrier by means of the vertical conveyor. The gist is that it is configured so that it joins in an acute angle in the middle part.

[0005]

[Action]

 According to the present invention, the majority of the multi-row cut culms are fed laterally by main feeding, and then the remaining feeds are merged in the vertical transporting section of the main transporter. It is easy to get familiar with each other, and the merging action of both is performed very well. Further, since the main transport grain culms meet at an acute angle, the transport posture is not disturbed, and the grain culm can be smoothly and reliably passed to the lifting transport device side.

In the rear of the raising device 4, a main carrier 15 and a sub carrier 16 located on the right side of the main carrier 15 are provided. In the main carrier 15, the majority of the total number of cuts (4 lines on the right side in the example) are cut culms from the already cut land a side (the outer right side of the machine in FIG. 2) to the uncut land b side (the same). It has a horizontal conveyance section 15a for laterally feeding toward the left side of the machine body) and a vertical conveyance section 15b for conveying from the conveyance end portion of the horizontal conveyance section 15a to the lifting conveyance apparatus 7 side, and has a conveyance action. The side has a substantially L shape in plan view. The main carrier 15 has a three-stage divided structure in which the height is changed in the culm direction and the stock feed 17, the middle feed 18 with a tine 18a, and the upper feed 19 with a tine 19a. In addition, the sub-transporter 16 is for feeding the remaining number of harvested culms (in the embodiment, two ridges on the left side) toward the already-cut land a, and the stocker corresponding to the stocker chain 14 on the right end side. The feed unit 20, the intermediate feed unit 21 with the tine 21a, and the upper feed unit 22 with the tine 22a are divided into three stages, and the transport merging portion J of the main carrier 15 and the sub carrier 16 is shown in FIGS. As shown in, the non-acting side of the raising device 4 is located rearward of the rear sides of the raising cases 4a and 4b facing each other, and is provided in a delta shape in a plan view. Then, the tines 21a and 22a on the side of the sub-transporter 16 are arranged so as to wrap on the main transporter 15 side in plan view at the transport merging portion J, and the left and right transport grain culms are joined. When entering the section J, in consideration of the attachment holding action by these tines 21a and 22a, it is ensured that the transported grain culms after merging are transported backward in a stable state held from the front, rear, left and right. .

Reference numeral 23 denotes a triangular inner cover provided on the front side corresponding to the delta-shaped transport merging portion J. The guide cover 23 is inclined along the guide passages of the main transport body 15 and the sub-transport body 16. It has guide surfaces 23a and 23b, and is detachably fixed to the rear side of the raising cases 4a and 4b through a mounting tool 23c such as a mounting bolt. Then, the transport grain culm on the side of the sub-transporter 16 merges with the transport grain culm on the side of the main transporter 15 at an acute angle (about 45 ° in the embodiment) at a midway point of transport of the vertical transport unit 15b. It is configured. Reference numeral 24 is an input pulley of the pretreatment unit 1, 25 is a transmission shaft to the pretreatment unit 1, 26 is a gear case, and 27 is a pretreatment frame.

In the above-mentioned embodiment, the combine of 6-row cutting was explained, but the present invention is not limited to the 6-row cutting combine, and a 5-row cutting or a large combine having more than 6 cuttings is also possible. Can be adopted.

In the above-mentioned structure, during the mowing operation, the standing culm of the field caused by the raising device 4 is cut by the cutting blade 10, and two pairs of the star wheels 11 and the transport belts 12 are used together. After being scraped and conveyed to the rear, the right four rows are laterally conveyed in the uncut area b direction from the already cut land a side by the main carrier 15 composed of the stock feed 17, the middle feed 18, and the upper feed 19. The direction of the main transport body 15 is changed from the end portion of the horizontal transport portion 15a to the vertical transport portion 15b. On the other hand, the cut grain culms for the left two rows are slanted from the uncut land b side to the vertical transport section 15b of the main transporter 15 by the sub-transporter 16 consisting of the stock feed 20, the middle feed 21, and the upper feed 22. After being conveyed rearward, it is merged into the conveying grain stem on the side of the main conveying body 15 at an acute angle in the middle of conveyance of the vertical conveying unit 15b. In this way, of the 6 harvested culms, the majority of the 4 culms are fed horizontally and the remaining 2 ridges are merged in the vertical transport section 15b of the main transporter 15. It is easy to get used to, and the merging action of both is performed very well. In addition, since it joins the main transport grain culm at an acute angle, the transport posture is less disturbed and the grain culm can be smoothly and surely passed to the lifting transport device 7 side.

Further, a guide cover 23 having inclined guide surfaces 23a and 23b along the transfer passages of the main carrier 15 and the sub carrier 16 is provided on the front surface side of the transport merging portion J provided in the delta shape. The respective transport grain culms are reliably guided and guided by the guide cover 23 without being tilted forward, and are transported to the merging portion J side while maintaining an orderly transporting posture. For this reason, the confluence action of the transported grain stems by the main carrier 15 and the sub carrier 16 is performed more smoothly.

By the way, the lateral feed section 15a of the main carrier 15 has a function of laterally feeding the cut grain culms for a majority of the total number of cuts from the already cut land a side to the uncut land b direction. Therefore, the width of the transverse feed section 15a in the front-rear direction is as narrow as possible, so that the driver's seat 6 and the cabin 6a behind it can be sufficiently secured in the space c, and there is no need to worry about the space for the driver's seat 6. . In addition, the driver's seat 6 can be arranged so as to bite into the pretreatment section as much as possible, which improves the front visibility, and the left end divider D ₁ projects outward from the machine width of the machine 2. Even if they are placed, they are visible from the 6th position in the driver's seat, so there is no problem.
