Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a divider mounting structure for a mowing part of a general-purpose combine.

[0002]

2. Description of the Related Art Conventionally, when harvesting soybeans or the like at a reaping section of a general-purpose combiner, a divider is attached. There is a spring adjuster formed by screwing, and the adjustment nut is attached as a double nut that can be joined to one side of the stay, or a double nut that can be joined to both sides of the stay. .

[0003]

[Problems to be Solved by the Invention] However, since the nut is double, it is necessary to operate both nuts at the time of adjustment, which requires two spanners, which is difficult and time-consuming. And the bolts interfere with each other to damage the thread of the bolt.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised in order to solve such a problem, to make it simple and to be able to suitably carry out the present invention. An upper end of a cylindrical tension seat to be fitted to a bolt is fixed to a lower surface of the adjusting nut screwed to the side, and a lower end of the cylindrical tension seat is joined along an outer peripheral arc surface of the stay. It is formed by forming a concave curved surface as possible.

[0005]

Therefore, while the bolt is being tensioned by the spring, the concave curved surface of the cylindrical tension seat is joined to the outer peripheral arc surface of the stay, so that the function of the double nut is adjusted in the same manner. Will be performed, and moreover, the bolt can be held by the cylindrical tension seat so that the bolt does not interfere with the stay.When adjusting the adjuster, the stay is pushed down, or With the lower end of the cylindrical tension seat remaining in contact with the stay, it can be easily adjusted simply by turning a single adjustment nut.

[0006]

1 to 4 show a first embodiment of the present invention. As shown in FIG. 2, when harvesting soybeans and the like, the cutting frames 7 on both sides attached to the front of the cutting section of the general-purpose combine are used. A mast 8 stands on the front and a divider 9 on the front.
Is mounted on the mast 8 via a fulcrum shaft 11, and a support rod 12 of a support wheel 13 is vertically moved on a support cylinder 12 fixed to the upper side of the mast 8. It is configured to be fitted in an adjustable manner.

A lower end of a support rod 2a having an upper portion serving as a bolt 2 is fixed to an upper surface of a support cylinder 16 loosely fitted to a support shaft 15 protruding from a side of the mowing frame 7.
A round bar-shaped stay 3 is laid horizontally inside a support plate 17 fixed to the rear end, and a bolt 2 and a supporting rod 2a are fitted into the stay 3 with play, and the support tube 16 and the stay A compression-type spring 1 is fitted to a support rod 2a between the bolt 2 and a cylindrical tension seat fitted to the bolt 2 on the lower surface of a butterfly-shaped adjustment nut 4 screwed to the tip of the bolt 2. The upper end of the cylindrical tension seat 5 is fixedly formed, and the lower end of the cylindrical tension seat 5 is formed with a concavely curved surface 6 that can be joined along the outer peripheral arc surface of the stay 3.

[0008]

Therefore, the concave curved surface 6 of the cylindrical tension seat 5 is joined to the outer circumferential arc surface of the stay 3 while the bolt 2 is being urged by the spring 1 so that the double nut is formed. The rotation of the adjusting nut 4 is stopped in the same manner as in the above function, and the bolt 2 can be held by the cylindrical tension seat 5 so that the bolt 2 does not interfere with the stay 3. so,
The spring 1 can effectively press the rear portion of the cutting frame 10 that can rotate about the fulcrum shaft 11 as shown by an arrow a. The spring 1 can be used to effectively press the cutting frame 10. By pressing down or keeping the lower end of the cylindrical tension seat 5 in contact with the outer peripheral surface of the stay 3 and rotating the single adjustment nut 4, the adjustment nut 4 and the cylindrical tension seat 5
Can be easily adjusted by moving it up and down along the bolt 2.

FIGS. 5 and 6 show a second embodiment and a third embodiment, respectively, which are substantially the same as those of the first embodiment as indicated by the same reference numerals. In the third embodiment, a pair of plates fixed to the lower end of the cylindrical tension seat 5 is bent to the concave curved surface 6 in the third embodiment. FIG. 7 shows another example, in which the adjusting nut 4 and the cylindrical tension seat 5 are integrally formed in a long hexagonal nut shape to form a concave curved surface 6 on the lower end surface thereof.

[0010]

As described above, according to the present invention, the bolt 2 is
The concave curved surface 6 of the cylindrical tension seat 5 is joined to the outer peripheral arc surface of the stay 3 in a state of being urged by the tension nut, so that the adjustment nut 4 has the same function as the double nut.
Will be effectively performed, and moreover,
The bolt 2 can be effectively held by the cylindrical tension seat 5 so that the bolt 2 does not interfere with the stay 3 and the screw thread is crushed unlike the related art.
Also, when adjusting the adjuster, the adjustment can be easily performed by pushing down the stay 3 or by rotating the one adjustment nut 4 while keeping the lower end of the cylindrical tension seat 5 in contact with the stay. It has the feature that it can be suitably implemented as a mounting structure for a divider of a mowing part of a general-purpose combiner.
