Description

[Detailed explanation of the invention] (a) Industrial application field The present invention consists of a center frame, a reaping frame, and a right frame that support the reaping/binding portion of a two-row reaping binder and slide while contacting the soil surface. This relates to mounting support structures such as.

(b) Prior Art In most conventional binders, the reaping frame, center frame, and right frame are integrated into the frame itself, and a binding mission case is placed on top of this.

As a variation of this, there is Jitsukō No. 49-2039,
There was one such as No. 51-173153 in which the center frame was fixed near the cutting blade stand.

(c) The problem that the idea aims to solve The purpose of the present invention is as follows.

Previously, the frame was integrated as a whole, and the center frame also protruded from the integrated right frame and reaping frame, but now the binding case 4 is fixed as a fixed base, and the center frame is also separate from this center frame. The structure is such that the bottom cover of the binding mission case can be removed by removing the frame and the right frame. To do this, only the main body side of the binding mission case 4 is tightened to the reaping frame mounting seat 27 to connect and secure it to the reaping frame 6, and the center frame, right frame, and reaping frame are connected to the binding mission case 4. It was designed to be attached to.

(d) Means for solving the problem The purpose of the present invention is as described above, and the configuration for achieving the purpose will be explained below.

FIG. 1 is an overall side view of the binder of the present invention. Figure 2 is also an overall plan view. Figure 3 is a partial cross-sectional view of the front of the binding mission case. FIG. 4 is a plan view of the binding mission case 4. FIG. 5 is a plan view of the center frame 1 in a fixed state. FIG. 6 is also a back view.

The overall structure of the two-row cutting binder of the present invention will be explained with reference to FIGS. 1 and 2.

A traveling transmission case 14 is provided on the left side of the engine 13. A traveling chain case 11 is pivotally supported on a shaft of the traveling transmission case 14 that protrudes further to the right so as to be vertically movable. Wheels 10, 1 are mounted on the axles protruding from the traveling chain case 11.
0 is supported, and wheels 10, 10 can be rotated vertically and protruded so that even wet fields can be harvested.

Next, the main frame 8 protrudes from the transmission case 14 toward the reaping frame mounting seat 27. The binding mission case 4 is supported and fixed by the main frame 8.

Another drive case 15 is also extended and fixed from the traveling mission case 14 to the lifting drive bevel case 19, and supports the binding mission case 4 via the shaft protection tube 20 and the auxiliary mission case 5. ing. Further, a mounting base 12 for a handle 18 is provided protruding from the main frame 8. A power transmission shaft is built into the shaft protection tube 20 mentioned above, and the power is divided into upper and lower parts by the lifting drive bevel case 19, and the upward power drives the left side of the lifting case and moves downward. Auxiliary mission case 5 with appropriate power
is being input. The cutting blade 23 and the stock head horizontal conveyance belt 24 are rotated by the auxiliary transmission case 5, and the power is transmitted to the binding transmission case 4.

Reference numeral 22 denotes a right-hand raising case, 22a a right-hand grass dividing plate, and 21a a left-hand grass dividing plate.

The present invention relates to the structure of the attachment part of the center frame 1 for fixing the grass divider plate 9 in the center.

The structures of the binding mission case 4, center frame 1, right frame 7, and reaping frame 6 will be explained with reference to FIGS. 3, 4, 5, and 6.

FIG. 3 is a front sectional view of the binding mission case 4.

A bottom cover 4a is fixed to the lower surface of the binding mission case 4. 16 is the release rod, 25 is the nodule axis, 1
7 is a tubercle frame, 30 is a needle, and 31 is a patch car. Next to the nodal shaft 25, there is a scraping wheel on the right side and a PTO shaft 2 for driving the lifting case on the right side.
6 is provided. 27 is the door shaft of the bundling door 35, 28 is the needle drive shaft, 29 is the packer drive shaft, 33 is the input shaft for two-row mowing, and 34 is also used when mowing one row, so that the bundling transmission case 4 can be used. This is the input shaft. In the present invention, the binding mission case 4 consisting of these structures is opened from below with the bottom cover 4a.
Tighten together with seat 2 of center frame 1,
3 is fixed.

As shown in FIG. 4, the middle part of the reaping frame 6 is first fixed to the bottom surface of the auxiliary transmission case 5 using the mounting bracket 6a, and after being bent at a right angle, the base part is welded and fixed to the reaping frame mounting seat 27. ing. Further, the front end of the main frame 8 is fixed to the reaping frame mounting seat 27.

The right frame 7 is fastened together with the bottom cover to the tip of the right side protrusion of the binding mission case 4, and is itself in the shape of a sled. A right grass dividing plate 22a is fixed to the tip.

The auxiliary mission case 5 extends to the left side of the binding mission case 4 in the case of a two-row cutting binder, and one is a pull-up drive bevel case 1.
9 is an input shaft to which power is transmitted via the shaft inside the shaft protection tube 20, the shaft 36 is a crankshaft for driving the cutting blade 23, and the other shaft is an input shaft to the binding transmission case 4. .

Center frame 1 has a rectangular seat 2 and another one.
The book seat 3 is fixed by welding, and the bottom cover 4a is fixed as shown in FIG.
It is fixed by tightening it together. However, the bottom cover 4a is not fastened together with the reaping frame mounting seat 27.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First of all, since the center frame and right frame are constructed separately, repair and inspection can be carried out by removing only the bottom cover 4a without changing the shape of the aircraft while fixing the binding case 4 to the main frame 8 side. This made maintenance easier.

Second, since the binding case itself is a strength support member and the bottom cover 4a is configured as a float so that it can slide directly on the ground, the length of the frame rod can be shortened and the weight can be reduced. It is becoming effective.
