Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a traveling device for a combine harvester, or a nine-speed traveling device capable of changing seven speeds in conjunction with the vertical movement of a harvester or a harvester.

The combine harvester is a reaper that harvests the culms in the 1iIl field.

It is equipped with a threshing machine for threshing the husks that have been harvested and transported, and a traveling device on which these machines are mounted.

This harvesting operation using a combine harvester is generally called round cutting 9 and is often carried out from the outer part of the field toward the center of the m-th order while moving m1aL. In this case, when you move forward while reaping and reach the turning position, you can move backward and leave the row of culms and then start again and go all the way (towards), or you can continue to move past the turning point. The harvester can be harvested by turning the reaper in one of two ways, either by moving straight ahead, turning six times, then entering the row of culm rows in the right angle direction, or by moving the reaper along with the culm row. Stop operation.

When making this 51st trip, the machine is rotated six times as described above, so it takes as much time as possible for each trip, and the machine goes straight for reaping. If it rotates at the low speed of Tasonoma\, the work efficiency is extremely poor.Therefore, conventionally, when the rotation position is reached, the gear is changed and the rotation is performed at high speed. In a combine harvester equipped with a device, the speed cannot be changed unless the running latch is turned off, so due to the inconvenience, the speed change 1. *This was a frequent cause of decreased work efficiency.

The present invention has been developed in view of the above points, and the traveling transmission is connected to the lifting device K11l of the reaper, and when the reaper is raised or lowered at a predetermined height or higher, the traveling speed is adjusted in conjunction with this. By changing the position of the machine, P1 can be used to increase the speed during rounding to improve work efficiency in low loss machines, and to reduce the speed during rounding in high-speed machines to make work safer. - Providing a timed combine harvester running device. Hereinafter, one embodiment of the present invention will be explained in detail based on the drawings.

Figures 1 and 2 show an entire embodiment of the traveling device according to the present invention, Figure 141 is a side view of a combine harvester implementing this, and Figure 2 shows the connection between the traveling device, its transmission, and a reaper. It is a 1lt cost structure diagram showing an I-construction. In the figure,
The combine harvester 1 has a pair of left and right rollers 2'tfi that perform Oj1.
Furthermore, a threshing machine 5 equipped with a handling barrel for threshing, a feed chain 4 for transporting threshed husks, a sorting device, etc. is mounted on the traveling frame 3 that connects these. In addition, on the side and diagonally in front of the threshing machine 5, there is a pilot's seat 6,
72) An operating device T having stock operating levers is provided.

In front of the threshing 1!16 (Z), a 1 m reaping section, generally indicated by the reference numeral 8, is arranged pivotably at the front end of the threshing section 95C) and supported by a reaping frame 9. This reaper is equipped with a weeding body 11 at the tip of a weeding rod 10 that extends from the lower end of the reaping frame 9 toward the ground along the ground to divide the culms in the field. On one side, a lifting device 12 is installed to raise up the resting @culm i. IS is a clipper-shaped O cutting blade that intersects with the dividing rod 10 to cut the root part of the grain culm O in the support field, and above it is a husk that transports the husk culm to the threshing machine 4. A culm conveying device 14 is supported by a support rod 15.

The reaping machine I, which is configured like a cylinder, has a hydraulic cylinder 1 connected to the reaping frame S and the traveling frame 3, and the reaping machine mouth is connected to the cylinder 1. If @ is operated from the cockpit S to break the extension by 1 meter, K.
The entire reaping frame @O is centered around the upper pivot point.
/The height of the cutting blade 13 above the ground is adjusted. The vertical movement of this %IMR machine 8 is carried out by the mower blade 1.
Not only is this done to adjust the cutting height in step 3, but the highest cutting height is also raised even higher when crossing ridges during the trip to the waterfall, and as mentioned in section 5, the machine height is raised even higher. When you move it t times, the bell will rise to the highest position as well.

On the other hand, an engine 1T and a traveling gearbox 1s are mounted on the traveling frame 3), and the output shaft 1B of the X-engine 11 is connected to the input shafts of the thresher 4 and the %l extractor 1a6 by belts, respectively. At the same time, it is drivingly connected to the intermediate shaft 20 by the Peltos 1. Furthermore, the intermediate shaft 20 and the input shaft 22 of the traveling gearbox 18 are connected to each other by a belt-type transmission device indicated by reference numeral 1823 in the entire twA. It serves as a traveling drive shaft 24 as a drive shaft. The transmission 23 includes a drive pulley 25 on the intermediate shaft 20,
Between the variable speed pulley 2S, which is arranged on the input shaft zz in the axial direction, and these two pulleys 21° and 26! A tension arm 2SO is pivoted to the free end of a tension arm 2SO, and a nine tension pulley 2s is bent to the belt 21. Then, the tension arm 2@ is rotated 6 times in the clockwise direction as shown in Figure 1. Due to the force of the nine-wheel belt 2T (0), the speed change pulley 2I is moved against the elastic force of the spring 3Q (D shown by the chain line in Figure 1). Open as shown, bell against speed change pulley 2) 27
0 action a is changed to a small name, and the running roller 2C) j1 which is driven by the input shaft 22 and therefore the running drive shaft 14 is configured as 5 so that the line speed is increased.

The changing operation of the changing device 180 is performed in conjunction with the raising and lowering operation of the reaper. Namely.

Hydraulic cylinder IIO cylinder jl that raises and lowers the reaper mouth
The large pipe holder 31 and the nine pipe holder S and O, which are fixed to the machine base in close proximity to the tension arm 2 of the transmission 23, are connected by a wire 'no' (Ib 33), Nine wires inserted into this wire pipe 3s $4C
) The I terminals are fixed to the reaping frame 9 and the tensioning arm 11, respectively.

This is because the compression cylinder 16 extends and the reaping frame moves in the upward direction of the cutting machine, and the tension blind arm swings clockwise as shown in Fig. 111 and runs. The running speed of the R-n-raz has been increased.

When the reaping frame ■ swings in the downward direction of the reaper $, the wire s4 loosens and the belt 27C)! Overcoming the force of the wire 14, the action of the bell) 270 on the speed change pulley 2 becomes very hot, and the running speed of the roller 20 is slowed down to reduce acidity. In addition, the wire s

is interposed, g-jobs wssorn range m-assts
While the os height is within the range of 5Il1, the tension of the wire $40 is absorbed by the Ox spring s, and the running speed is not increased.When the os height exceeds the range of 9, the power cable arm 1F swings for the first time. The configuration is such that speed increase is started when the

The operation of the combine harvester 1 constructed as described above will be explained. When the machine moves both ways, the field OI and the culm are raked by the cutting body 11, and then the tip part is pulled up by the device 12, and the root part is cut off by the cutting blade IS. The harvested large culm is caught and transported by the shell culm conveying device 114, and the root S is pulled by the feed chain 4 and transported, and is also supplied to the handler. 11111. In this case, the cutting height is adjusted according to the situation. In other words, use the O operation from lI6 to close the hydraulic cylinder 1@
When the cutting frame $ is extended, the cutting frame $ swings, the height of the cutting blade 1s above the ground changes, and the cutting height is adjusted. In this case, Jl that the wire 84 stretches as a result of l1JIIlkK of the reaping frame is within the range of extension due to the elasticity of the spring 3!10, so there is no need to move the tension arm 2. % travel speed is changed.

Then, when the machine reaches the 13Iri position, the machine is moved backwards) and the second job WaS is separated from the uncut culm O east train, and the accompanying method is carried out using methods such as During the rotation operation, a'A dispersion is stopped. Namely.

When the hydraulic cylinder 16 is extended by operation from the cockpit 6 and the reaping machine is raised to the highest position and the reaping machine is stopped, the wire 34 is pulled as the reaping machine 90 rises and the spring 3s is extended, and its elasticity is Since the extension limit is exceeded, the tension arm 2 swings, and its action S on the speed change pulley 2 (due to the tension of the belt 27) becomes small and the traveling speed W1 increases. After turning, the cutting 4118 is lowered before the cutting body 11 cuts a new row of culm rows.

At the initial stage of descent, the traveling speed is decelerated, but when it reaches a predetermined speed, the tension of the spring 35 is overcome by the tension of the belt 21, and thereafter the traveling speed does not change even if the cutting height is adjusted. In this way, the traveling speed of one machine is set to a low speed suitable for reaping while the machine is reaping in one step.
The rotation jlK is increased in speed in conjunction with the upward movement of the reaper 411I, and after the rotation is again decelerated to the original speed in conjunction with the downward movement of the reaper 8. In other words, the work efficiency is improved by increasing the speed while the reaper is running, and there is no need to operate the latch gear shift lever, etc., which performs the IlO increase/deceleration operation (linked to the raising and lowering operation of the reaper). Since this is done automatically, there is no risk of tampering with the operation.

In addition, in this embodiment, the wire 340II force t@U
Pull spring 35! [I] As a spring example, a compression coil spring may be used, and after this is compressed to a predetermined pressure, the tensile force γ-arm 2 starts to oscillate. The transmission device 2s is not limited to the belt type shown in this embodiment, but may be a chain type, gear type, or the like. Furthermore, the transmission 231: The connection lateral movement that is linked to the lifting and lowering operation of the mowing machine lifting device is not limited to the connection by wire, and may be other mechanical II connection using a rod or the like, or may be electrically connected. In addition, in the example of one am, the running speed is increased when the machine runs 0 times, and 6 is like a large combine harvester.
[For models with a fast running speed, the running speed may actually slow down and become round when turning, so in this case, this can be achieved by replacing the speed change pulley 26 and the drive pulley 2s, etc. can.

As is clear, according to the present invention, the traveling gear of the combine is connected to the lifting device of the cutting machine, and the reaping rod is raised to a predetermined height. By making the 411 so that the machine's 0@ line speed changes in conjunction with the elevation or descent at the platform position, operate the latch, etc. that changes the machine's running speed when the machine's OwA line is in motion. The speed is automatically increased without any movement, and the speed is automatically returned to the original speed after turning. This improves work efficiency and prevents a decrease in work efficiency caused by neglecting the operation.
