Description

[Detailed description of the invention] The present invention provides a power source for the upper part of the lifting case, which is attached to the back of the lifting case, which is installed diagonally rearward and upward from the front part of the lifting frame extending to the front of the fuselage. This invention relates to a lifting device for a reaping and harvesting machine, which has a support that also serves as a transmission case for transmitting power, and is provided upright from a fixed member at the lower part of the machine body.

In this type of lifting device, the upper and lower parts of the lifting case are connected and supported by the lifting frame and pillars as described above, and are supported relatively firmly. The reaction force when raising the aircraft tends to cause vibrations such as lateral and vertical vibrations (in other words, the upper end of the raising case is supported by a rigid strut that also serves as the transmission case, but the lower end extends to the front of the aircraft). Since the lifting case is connected to the lifting frame which is in a cantilever supported state, when the lifting case is viewed from the front, the lower end of the lifting case swings with the upper end of the pillar that also serves as the transmission case as a fulcrum, and the lower end of the lifting case swings. The lifting case is tilted against the culm, and when the stem culm is untangled, the lower end of the lifting case returns to its original position, and when the lifting case is viewed from the side, the upper and lower ends of the lifting case are used as fulcrums. Then, the middle part of the relatively long lifting case bends, and when the stem culm is untangled, the middle part returns to its original shape.
In this way, by intermittently raising the entangled stem culms, horizontal and vertical vibrations occur.

In addition, uncut stem culms that pass through the side of the lifting device as the aircraft advances tend to fall down and enter between the lifting case and the strut in this type of lifting device, and this causes the lifting However, problems such as hindering the conveyance of the stem culm to the rear, and tearing off the ears of the uncut stem culm itself that have entered the area arise.

For this reason, in the past, a weeding rod etc. was installed at this location, but since such a weeding rod is in point contact with the stem culm, especially in the case of a long culm, it is difficult to The panicles that protrude upwards sometimes fall down, and if the dividing rod is set high, the force to prevent the short culms from falling down is sufficient.

The present invention solves both of the above problems at once with a simple structure in which a plate-shaped reinforcing frame is connected between the lifting case and the support, and by rationally arranging this reinforcing frame. Inspection of the auxiliary conveyance device and reaping device installed at the lower back of the lifting device.

This is intended to make adjustments etc. easier.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

The figure shows that while the crawler traveling device 1 is running, a cutting section consisting of a lifting device 2, an auxiliary conveyance device 14, a reaping device 3, etc. at the front of the machine is used to raise and reap the stem culms to be planted. It shows a combine harvester that is vertically transported to a rear threshing device 5 for threshing processing by a vertical transport device 4, and is connected to a main body consisting of the traveling device 1, threshing device 5, etc. so as to be able to move up and down, and also serves as a transmission frame. The reaping section is connected and supported on the roadside side of the disposed lifting arm 6.

Further, the lifting device 2 of this reaping section is constructed as described below.

That is, a reaping mission case 7 serving as a fixing member at the lower part of the machine body connected and supported by the lifting arm 6 is arranged to face in the lateral direction of the machine body, and the cutting blades 8 are attached to the front part of the mission case 7. A reaping device 3 is configured.

Three lifting cases 10 are installed diagonally from the front of the three lifting frames 9 extending from the mission kusuf to the front of the fuselage toward the rear and upwards. On the back of case 10, this case 10...
・A column 11 that also serves as a transmission case to transmit power to the upper part of the
A reinforcing column 12 is erected from both ends of the mission case 1, and a horizontal transmission frame 13 and the lifting case 10 are interposed over the upper portions of these columns 11 and 12.
The upper parts of... are interlocked and connected to constitute the lifting device 2.

Further, the lifting device 2 is configured. In addition, a support 11 facing the uncut stem culm is also provided, similar to the upper part of the lifting case 10' of the lifting case 10 on the side facing the uncut stem culm during normal rotation work of the machine. A plate-shaped reinforcing frame 15 is connected between the two parts.

An opening for exposing the auxiliary conveyance device 14 and the reaping device 3 is formed at the lower part of the reinforcing frame 15, and as shown in FIG.
A side wall 16' extending downward from the conveying cover 16 of the conveying section 14', which is on the side closer to the uncut stem culm and acts on the middle part of the stem culm, is arranged to cover the opening. .

The conveyance cover 16 can be easily attached or detached by removing the upper butterfly bolts 17.

Further, a grass dividing rod 18 is arranged on the lateral outer side of the body on the side of the uncut stem culm.

According to the above configuration, when the machine body performs normal mowing work etc., uncut grass that tries to fall over the top of the dividing rod 18 between the lifting case 10' and the strut 11 into the body of the machine body can be removed. The tip side of the stem culm is guided by the reinforcing frame 15 and does not fall down.

Note that the relatively short culm on the uncut side is prevented from falling inward only by the dividing rod.

In addition, the lifting case 10' is connected and supported by the reinforcing frame 15 supported by the pillar 11, and is firmly supported, so that it does not swing horizontally or vertically due to the reaction force of the planting stem culm lifting action. There aren't many.

Incidentally, when inspecting or adjusting the auxiliary conveyance device 14, by removing the conveyance cover 16, inspection or adjustment of this portion can be easily performed from the side.

In summary, the pulling device for the reaping harvester according to the present invention is as follows:
At the back of a lifting case 10, which is diagonally installed rearward and upward from the front part of the lifting frame 9 extending to the front of the fuselage, there is a case that also serves as a transmission case for transmitting power to the upper part of the lifting case 10. In a lifting device for a reaping and harvesting machine in which a strut 11 is erected from a fixing member at the lower part of the machine body, a lifting case 10' on the outside of the machine body is provided with an upper part of the lifting case 10' and the strut 1.
The plate-shaped reinforcing frame 15 is positioned and connected to the outer side of the machine body on the uncut side, so that it has the following advantages.

(2) A reinforcing frame 15 is connected and supported across the upper side of the lifting case 10' and the side of the sturdy column 11.

Therefore, the reinforcing frame 15 prevents twisting of the lifting case 10' relative to the support column 11, and also prevents deflection of the longitudinally intermediate portion of the case 10, thereby preventing lateral vibration of the lifting case 10. It is possible to suppress vertical vibration and increase the strength of the entire lifting device, and by using the reinforcing frame 15, which is a strength member, it is possible to connect uncut stem culms in the planted state and those in the lifting path. By separating the cut stem culm from the cut stem culm, the uncut stem culm can be prevented from collapsing.

■ Since the reinforcing frame 15 is connected as shown in ■ above, it is possible to leave the lower part open, or simply place a removable cover that does not require special strength. As a result, the various devices installed at this location can be easily inspected and adjusted.

∎ In other words, the present inventors raised the reinforcing frame 15 and placed it across the case 10 and the pillar 11.
Since this is a member configured to have sufficient strength to serve as a transmission case, sufficient strength can be achieved by simply raising the reinforcing frame 15 and connecting it only to the upper side of the case 10'. As a result, by using a plate-shaped reinforcing frame 15 with a relatively small area, it was possible to achieve the above effect (2).
