Description

[Detailed Description of the Invention] The present invention relates to a grain culm lifting device in the reaping section of a combine harvester.

That is, a grass-pulling case having grass-pulling tines that protrudes forward and moves forward is arranged between the two grass-pulling cases each having a grass-pulling tine that protrudes and moves in the lateral direction of the opposite direction. In the reaping section of the combine, before the grain culm is pulled up in the same way as before, it is possible to reliably separate and pull up the grain culm that is lying down in the horizontal direction, and after that, the soft rods can be pulled up in the horizontal direction. It is possible to raise the grain reliably and well with both lifting cases to prevent it from falling over and to prevent the two grain culms from getting entangled, and to provide good support and transmission of the grass pulling case. The purpose of the present invention is to provide a simple structure that allows the cutting width to be widened and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the front part of the combine, and shows the threshing section A mounted on the machine body supported by the crawler 6.
A reaping section B is installed in front of the reaping section B, and the reaping section B has pulling tines 1a and 1b that protrude and move laterally in opposite directions, respectively, at the rear of grass division plates 7a and 7b on both front sides. Both lifting cases 2a and 2b are installed diagonally in parallel, and both raking wheels 9 and both raking belts 10 are installed above the cutting blade 8 which is installed horizontally at the rear lower part of both lifting cases 2a and 2b. A lower conveyance chain 11 and a tip conveyance tine 12 are respectively extended rearward from that part and above the lower conveyance chain 11, and a vertical conveyance chain 13 is provided obliquely at the rear, so that the structure is similar to the conventional structure.

In addition, both the lifting cases 2a and 2b are installed diagonally apart from each other so that the tips of the corresponding lifting tines 1a and 1b are separated from each other.
The power transmission case 15 is arranged so as to transmit power from below through a transmission pipe 14 extending over the upper rear side of the transmission case 2b.

A grass cutting case 4 having grass cutting tines 3 that protrude and move forward is installed diagonally so as to be separated from the middle of both the grass pulling cases 2a and 2b. plate 5 connected to
a is lengthened in the vertical direction and extended rearward, and the lifting tines 1a,
A guide plate body 5 extending from the front to the rear is installed between the two lifting cases 2a and 2b so that the tips of the two lifting cases 1b approach each other, and the lower part of the guide plate body 5 is attached to the reaping frame 16, and the upper part is connected to the two lifting cases 2a and 2b. Case 2
The plate body 5a, which is connected to the gates 17 extending between the upper parts of the guide plates 5a and 2b and joined to the side surface of the guide plate body 5, has a plurality of longitudinal adjustment slots 1 extending upwardly and downwardly.
8 are formed respectively, and bolts and nuts 19 to be inserted into the guide plate body 5 are respectively attached to the elongated holes 18, and the elongated holes 18 are used to raise the weeds so that the case 4 can be moved and adjusted in the front and back direction. do.

In addition, a support rod 21 extends rearward from the lower part of the grass dividing plate 20 provided diagonally in front of the lower part of the grass pulling case 4.
is slidably inserted into the reaping frame 16 and fixed with a set bolt 22, and a gear box is installed at the end of a transmission pipe 23 extending laterally from the upper side of the weed pulling case 4. 24 are connected to each other, and the gear box 25 connected to the lateral end of the transmission case 15 and the gear box 24 are transmission-connected by a telescopic transmission pipe 26 that is freely retractable.

Therefore, the guide plate body 5 becomes a support member and can support the weed raising case 4,
The split raising case 4 is the double raising case 2a, 2.
Since it protrudes further forward than b, transmission can be transmitted from the upper side through the transmission pipe 23. Also, there is a guide plate 5 between the two lifting cases 2a and 2b.
Since the two lifting cases 2a and 2b are interposed, the interval between the two lifting cases 2a and 2b is larger than that of the conventional type, and the mowing width can be widened.

During combine harvesting work, the weed pulling case 4, which is the forwardmost part of the machine, moves between the rows and pulls up the grain culms that are lying down laterally using the weeding tines 3, and then both the weed lifting cases 2a and 2b are used. The lifting tines 1a and 1b are respectively pulled up, but since the guide plate body 5 is installed between the two lifting tines 1a and 1b, the grain culms of both rows are pulled up by the lifting tines 1a and 1b, respectively. 1b, and the soft grain culms of both rows are prevented from becoming entangled because they are partitioned by the guide plate body 5.

Further, by adjusting each elongated hole 18 and the bolt/nut 18, the weed pulling case 4 can be adjusted in forward and backward movement, and can be adjusted according to the condition of the grain culm.

In this way, the present invention includes a weeding case having movable weeding tines that protrude forward, located between the two movable cases each having a movable movable weeding tine that protrudes in the opposite direction. In the reaping section of the combine, the grass cutting case is diagonally provided so as to protrude to the front side away from between the two cutting cases, and the guide extends rearward from the rear part of the grass cutting case. Since the plate body is constructed by extending between the two lifting cases so that the lifting tines of the both lifting cases approach each other on both sides, it is necessary to The weeding and raising case at the front can reliably weed and raise the grain culms that are lying down laterally, and after that, the guide plate is interposed to prevent the soft stems from falling laterally. In addition, the two-rowed grain culm can be raised reliably and well by both raising cases without getting entangled, and when configured as in the above embodiment, the grain raising case can be well supported from the guide plate side. The structure is simple, as it is possible to transmit the power to the weeding case without being obstructed by the case, and by interposing the guide plate, the space between the two cases can be widened to widen the cutting width. It has the feature that it can be carried out suitably.
