Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a narrow guide for a combine harvester that reaps and threshes grain culms.

(B) Prior Art The narrow guide in a conventional combine harvester is attached to a pre-processing device, and its rear part extends along the side of the machine.

(c) Problems that the invention aims to solve In recent years, combine harvesters have become larger and taller, but because there is no suitable scaffolding, it is difficult to get on and off the taller machines for maintenance inspections or to work at heights. Therefore, maintenance and inspection work was extremely difficult and dangerous.

(d) Means for solving the problem The present invention is based on the present invention, in which a pre-processing device consisting of a reaping device and a grain culm conveying device is attached to the front of a machine platform equipped with a threshing device, and the machine platform is moved forward and backward. In a combine constructed by assembling a plurality of horizontal frames, a narrow guide extending from the side of the reaping device to the side of the machine stand is divided into front and rear parts, and a rear narrow guide corresponding to the threshing device of the machine stand, At least a pair of support rods whose outer ends are connected by front-back foot members and extend laterally are installed, and these support rods are inserted into the horizontal frame of the machine base and removably installed. At the same time,
By configuring the rear narrow guide to be movable and adjustable between a position where it acts as a guide for the standing grain culm when it is pushed in the most, and a work platform position where it is pulled out further to the outside of the machine platform and the step member is separated from the frame body, the above-mentioned feature is achieved. The problem was solved.

(e) Function The front narrow guide is attached to the pre-processing device, and when performing reaping and threshing work, the support rod of the rear narrow guide is inserted from the side to the deepest part of the frame of the machine. The narrow guide at the rear of the machine guides the erect grain culms on the sides so that they do not fall toward the combine harvester side, and is attached to the side of the machine when performing maintenance and inspection of the threshing device or straw conveying device from the side of the machine. When the rear narrow guide is pulled out and attached to the frame, the narrow guide and the step member become a workbench, allowing maintenance and inspection work to be carried out quickly and safely.

(f) Example An example of the present invention will be explained with reference to the drawings.
Reference numeral 1 denotes a threshing device mounted on one side of a machine base 3 having a traveling device 2. On the other side, an operation panel 4, a pilot's seat, a grain tank 5, an engine, etc. are arranged in order from the front. A pre-treatment device consisting of a reaping device 6 consisting of a weed cutting body 6a, a grain culm pulling body 6b, etc., and a cutting blade, and a grain culm conveying device 7 is attached to the front part of the 1 so as to be tiltable up and down, and a cutter is attached to the rear part. A waste straw processing device 8 such as a binding attachment and a dropper is installed, and a waste straw conveying device covered with a cover is interposed between the removal culm of the threshing device 1 and the waste straw processing device 8. be.

Further, the machine stand 3 is constituted by a frame body 10 consisting of a plurality of horizontal cylinders, and a frame body 11 consisting of a rectangular tube extending in the front and back direction.

Furthermore, the narrow guide 12 is the front narrow guide 1.
2a and a rear narrow guide 12b, the front narrow guide 12a is attached to the preprocessing device and guides the grain culm on its side, and the rear narrow guide 12b is attached to the side of the machine base 3. to guide the grain culm.

The rear narrow guide 12b has a front end curved toward the fuselage side, and has lateral support rods 13 and 14 at the front and rear of the straight portion, respectively. The base of the rear narrow guide 12b is welded to the rear narrow guide 12b, and the rear support rod 14 has two receiving tubes 15 and 16 on the base side, and the rear narrow guide 12b is loosely fitted into one of the receiving tubes 15,
A step member 17 protruding rearward from the front support rod 13 in parallel with the rear narrow guide 12b is loosely fitted into the other receiving tube 16, so that the front and rear movement can be adjusted. Insertion rods 18, 1 having the same diameter as the support rods 13, 14 are provided at the tip of the support rods 13, 14.
8 are connected by fulcrum pins 18a, 18a in the front-rear direction so that they can be bent vertically.

In the combine harvester described above, the front narrow guide 12a is attached to the pre-processing device as shown in FIG.
Lift up the fuselage side end of 14 and insert the inserts 18, 18.
into the frames 10, 10 of the machine base 3, then lift the rear narrow guide 12b and push it into the part corresponding to the bent part of the support rod 14, and then remove the push bolt 2.
Tighten 0.0, 20 to guide the erect grain culm.

Therefore, when performing maintenance or inspection on the thresher 1 etc. during or after work, loosen the push bolts 20, 20, pull out the rear narrow guide 12b as appropriate,
After tightening the push bolts 20, 20, climb up using the rear narrow guide 12b and step member 17 as a work platform, open the cylinder cover and perform maintenance and inspection on other parts of the handling room, and do maintenance and inspection on the other side of the aircraft in the same way. You can also do this.

In addition, when performing maintenance and inspection on the waste straw conveying device or the waste straw processing device 8, the rear narrow guide 12b is removed and moved rearward, and the support rod 14 is moved and adjusted as shown in FIG. 13, 14 to match the spacing between the frames 11, 11, insert the insertion rods 18, 18 attached thereto into the frames 11, 11, lift the rear narrow guide 12b, and insert the support rods 13, 14. Push the push bolt 20,
20, and in this state, tighten the rear narrow guide 12.
b and step member 17 to perform maintenance and inspection on the fuselage from the rear of the fuselage.

(G) Effects of the invention As described above, the present invention includes a pre-processing device consisting of a reaping device 6 and a grain culm conveying device 7 mounted on the front part of the machine platform 3 on which the threshing device 1 is mounted. In the combine harvester constructed by assembling a plurality of frames 10 and 11 in the longitudinal direction and the lateral direction, the narrow guide 12 extending from the side of the reaping device 6 to the side of the machine stand 3 is divided into front and rear parts, and the machine stand 3 At least a pair of support rods 13 and 14 whose outer ends are connected by a foot member 17 extending in the front and rear direction so as to extend laterally are attached to the rear narrow guide 12b corresponding to the threshing device 1, and these support rods 13 , 14 as the horizontal frame 10 of the machine base 3
At the same time, the rear narrow guide 12b is inserted into and removably attached, and the rear narrow guide 12b is pushed in to the maximum position where it acts as a guide for the standing grain culm, and the step member is separated from the frame body 10 by pulling it out to the outside of the machine. The rear narrow guide 1 is configured so that it can be moved and adjusted to the stand position.
If 2b is pushed in toward the side of the fuselage as much as possible, the erect grain culm can always be guided outward in an appropriately pushed apart state without special care.

In addition, when performing maintenance inspection during work or at the end of work, by attaching the rear narrow guide 12b to the frames 10, 10 with the rear narrow guide 12b pulled out, the rear narrow guide 12b and the step member 17 can be used as a wide workbench. Therefore, maintenance and inspection work can be performed easily, quickly, and safely even at high places.
