Description

[Detailed description of the invention] The present invention relates to a reaping section in a combine harvester.

-n〉, the combine uses a cutting height sensor that detects the condition of the field surface to automatically move the cutting unit down by 1-0 degrees so that the cutting height of the culm is always the same. It's being adjusted.

However, in the conventional con/<in, the rear end of the reaping section is pivoted to the machine body, a grass dividing rod is provided at the curved end of the reaping section, and the cutting section is installed in the middle of the reaping section. Since the blade is M-shaped, when the height of the cutting blade is adjusted down by 1-0 to match the height of the culm, the dividing rod rotates in an arc around the shaft attachment part. Therefore, when working in fields such as dry fields and wet fields where the amount of sinking of the combine running part varies greatly, when the cutting blade is aligned with the grain culm, the relative front 11r1 relationship between the cutting rod, the pulling device, and the cutting blade is It went awry and the mowing process couldn't be done smoothly. In particular, in the case of wet rice fields, the running part of the combine is greatly sunken, and when the supporting arm is moved upward to align the position of the cutting blade with the culm, the relative positional relationship between the weeding rod and the pulling device is considerably changed. It's crazy.

Conventional models, except for the walking type, have not taken measures to deal with this.

The walking type model was as shown in Figure 1, where A is the wheel, B is the walking steering wheel, and C is the walking steering wheel.
is the triggering device, D is the minute G:,: body.

E is a support tube, F is a lower frame, and G is a two-way moving rod.The lifting device C and the splitter were designed to move up and down together with the support tube E.

However, since the power transmission shaft passes through the support tube E, the power transmission structure becomes complicated if the support tube E is moved up and down.

The present invention provides a threshing section 2 on the upper part of the traveling device 1, and at least a dividing rod 5, a pulling device 9, and a cutting blade section 1 on the iiQ section of the traveling device 1.
9, the reaping part 4 is provided with a support arm 23 so as to be movable downwardly, and +iiij support I-stomach Dii23
The base of the vertical moving rod 7 is set at -111 by the horizontal axis 8 at the tip of the
1 stop, and place the W rod 5 and the lifting device 9 on the vertically moving part of the vertically moving rod 7. The upper part of the lifting device 9 has a sliding structure on a member protruding from the support arm 23 side. Threshing Bl+ 2 is provided at the reaping section of the attached combine harvester and at the top of the crawler running section 1, and a support arm 23 is provided on the front side of the machine with a horizontal shaft 24.
(The part is pivoted, and the support arm 23 is connected to the hydraulic device 26.)
The base of the support frame 6 is fixed to the tip of the support arm 23, and the base of the vertically movable rod 7 is fixed to the tip of the support frame 6 with a horizontal shaft 8. The lower end of the lifting device 9 is fixed to the vertically moving part of 7, the parting rod 5 is fixed to the tip of the lower moving rod 7, and the upper part of the lifting device 9 is provided with a long hole 14 with the vertical blade direction. A fixing screw 14 is inserted into an elongated hole 14 in the upper part of the support tube 13 that projects downward from the tip of the support tube 13.
The above-mentioned defects can be overcome by providing a reaping section in a combine harvester in which a fixing screw 14'' is inserted into the elongated hole 14 and fixed.

An embodiment of the present invention will be described with reference to the drawings. 1 is a crawler running part, 2 is a threshing part provided on the upper part of the crawler running part, 3 is a threshing part 2
This is a shell culm supply device that supplies shell culms into the inside of the container. The threshing section 2
A reaping f:R4 is provided in front of the. Reference numeral 5 denotes a weeding rod provided at the frontmost end of the reaping section 4, which can be accessed at the tip of the vertically movable rod 7. ” - The rotating rod 7 is attached to the tip 1 of the support frame 6.
It is rotatably provided horizontally 1141+8. Reference numeral 9 denotes a lifting device; 111, the end of which is pivoted to the vertically movable rod 7 through a port 20; Lifting case 1 of lifting device 9
A chain 11 is wound vertically inside the chain 11, and a plurality of lifting lugs 12 are attached to the chain 11 at regular intervals. The upper side of the lifting case 10 is attached to a support tube 13 provided with a rotation transmission shaft so as to be freely adjustable in the length direction. That is, the elongated hole 14 is formed in the second part of the lifting case 10, and the support tube 13
It is fixed by a fixing screw 14'' protruding from the side.In other words, the chain 11 is rotated by a sprocket fixed to the transmission shaft in the support cylinder 13, and the sprocket I
* is engaged with a chain different from the chain 11, so that the lifting device 9 can be moved up and down independently of the support tube 13.

Reference numeral 21 denotes a cutting blade portion fixed to the lower side of the support frame 6.

In addition, a cutting height sensor is provided on the top side of the cutting frame 6 to detect irregularities in the field and automatically adjust the height of the cutting section 4. Reference numeral 23 is a support arm, with its base side facing the machine body. The base of the reaping frame 6 is fixed to the tip of the support arm 23 by a horizontal shaft 24, and the vertically movable rod 7 is fixed to the tip of the reaping frame 6 by a horizontal shaft 8.

26 is a hydraulic device that moves the reaping section 4 up and down, 27 is a root conveying device, 28 is a tip conveying device, and 29 is a driver's seat.

Next, we will discuss the effect.

When the weeding rod 5 of the combine is aligned with the panicle and the cutting height ξ of the reaping section 4 is adjusted by the hydraulic device 26, the drying 1. In IJ work, the crawler of the running section 1 is the same as in the field, so the height hl of the reaping section 4 is slightly higher than the ground surface, and the height h2 of the pulling lug 12 is the height at which the lodging culm can be raised. Therefore, the height h3 of the weeding rod 5 is close to the ground.

Therefore, the work can be carried out as is.

In the work at lbA IIJ, the crawler of the running section l
1 of the reaping part 4 because it sinks downward by h4 with respect to the field.
°1: In order to maintain the J-sa at hl as in the dry field, the hydraulic device 26 is used to raise it slightly.

Then, the height h2 of the lifting lug 12 and the height h3 of the dividing rod 5 are
As shown in Fig. 4, it is considerably higher than in Fig. 2, and the balance is lost.

However, in the present invention, the vertically movable rod 7 is fixed to the distal end of the reaping frame 6 fixed to the distal end of the support arm 23 by means of a horizontal shaft 8, and the vertically movable lever 7 is equipped with a splitting rod 5 and a pulling device 9. For installation, when the vertical moving rod 7 is moved downward as shown by the solid line in FIG. and maintain the proper position of the lifting lug 12. That is, since the lifting device ξ9 can adjust the lifting device i 9 by approximately the length of the lifting lug 12 through the elongated hole 14, the lifting case 10 of the lifting gear 9 can be pulled down, and the reaping part 4 can be adjusted. The height h2 of the lifting lug 12 can be maintained in the state shown in FIG. By moving the center to the lower blade, the weeding rod 5 can be returned to the height h3 in Fig. 2, and can be adjusted to the optimal position depending on the field.

As described below, the present invention provides a threshing fζ on the upper part of the traveling device 1.
