Description

[Detailed description of the invention] The present invention relates to a mounting structure for the reaping pre-processing section of a combine harvester, in which the reaping pre-processing section is attached to a pair of left and right columns installed upright on a traveling machine base so as to be able to swing vertically. It is an object of the present invention to enable a reaping pretreatment part to be firmly attached to a traveling machine stand even with the simple structure used.

Next, embodiments of the present invention will be described based on illustrative drawings.

A driving section 2, a driving section 3, and a shelling section 4 are mounted on a crawler-type traveling machine base 1, and as the machine moves, a planted shell culm is raised and harvested, and the reaped shell culm is transferred to the starting end of the shelling section 4. The reaping pre-processing section 5 supplies the
It is attached to the front part of the traveling machine stand 1 to constitute a combine harvester.

To configure the reaping pretreatment section 5, a transmission case 6 is attached to the upper end side of a pair of left and right columns 7, 7 erected on the traveling machine stand 1 so as to be able to swing up and down by a hydraulic cylinder 8, and is pulled up. A pulling device 9 and a reaping device 10 for the culm, and a conveying device 11 for the cut culm are attached to the transmission case 6, and the cutting height can be adjusted by adjusting the mounting angle of the transmission case 6 with respect to the traveling machine base 1. It is configured to do so.

To configure the transmission mechanism for the reaping pre-processing section 5 and the shelling section 4, as shown in FIG. The belt transmits the rotational force of the input shaft 15 of the traveling transmission M to the transmission mechanism 14 for the handling cylinder 12 and shelling feed chain 13 located behind the transmission case 7, respectively, and inputs the rotational force of the input shaft 15 of the traveling transmission M into the transmission case 6. and is transmitted to the lifting device 9, the reaping device 10, and the conveying device 11.

As shown in FIGS. 2 and 3, the case 16 for the transmission mechanism 14 is constructed across the upper ends of both the columns 7, 7, and the transmission case 16 is installed between the left and right columns 7, 7. By effectively utilizing it as a connecting member, consideration is given to simplifying the structure and ensuring that the support column 7 can be firmly installed on the traveling machine base 1.

In summary, the reaping pre-processing part mounting structure of the combine according to the present invention is such that the reaping pre-processing part 5 is vertically swingably mounted on the pair of left and right columns 7, 7 installed upright on the traveling machine base 1, and the driving part 3 It is characterized in that a case 16 for a transmission mechanism 14 from the shell to the shelling section 4 is constructed across the upper end sides of both the pillars 7, 7.

In other words, since the transmission case 16 is effectively used as a connecting member between the left and right columns 7, 7, the column 7 can be firmly erected on the machine base 1 with a simple structure that does not require any special connecting members. cost aspect,
It has become possible to securely attach the reaping pre-processing section 5 to the machine base 1 while making the manufacturing process advantageous.
