Abstract

PROBLEM TO BE SOLVED: To provide the grass-dividing rod structure of a combine harvester, capable of avoiding the generation of troubles such as the breakage of unreaped grain straw stems, capable of well shaking down rain dewdrops, and improved in a threshing performance by disposing a grass-dividing rod in a state capable of being revolved on a longitudinal axis along the travel direction of the frame. SOLUTION: The grass-dividing rod 13 disposed on the lateral outside of a travel device 1 supporting a frame 2 in a travelable state along the travel direction of the frame is made up in a state of being revolved on a longitudinal axis Y2 along the travel direction of the frame. A plurality of the grass-dividing rods 13 are preferably disposed in different phases on the longitudinal axis Y2, and an air blower 18 for outward blowing air toward non-reaped grain straws on the lateral outside of the frame is further disposed on the front side of the travel direction front end of the grass-dividing rod 13.

2. Description of the Related Art Conventionally, as a branching rod structure of this type of combine, for example, as disclosed in Japanese Unexamined Patent Publication No. 6-276831, a posture is maintained in a state of being projected laterally outward of a crawler traveling device. It is known that the weeding rods are so constructed that the uncut grass culms are laterally laterally laid so as to prevent the uncut grass stems from falling toward the fuselage side.

However, in the above-mentioned conventional structure, since the sward rod is kept in a constant posture, the uncut side grain stem is slid by the stalk rod. As the sliding is concentrated on only a part of the culm of the uncut grain, there is a risk that it will be bent in the middle of the culm, and it was broken like that. There is a risk that the tip part of the thing will fold near the root of the plant, and mud will adhere to the tip.Therefore, when the cutting is performed later and the threshing process is performed, the mud attached to the tip part will clog the threshing device. However, there is a problem in that threshing treatment after cutting is difficult to perform due to, for example, particles being shattered during cutting or during transportation. Moreover, since the weeding rods only come into contact with the uncut muddy culms in a sliding state, the effect of shaking off the rain dew on the grain culm having rain dew is also weak.

(Operation) According to the configuration of claim 1 of the present invention, the weed rod provided on the lateral outside of the traveling device that supports the aircraft so that the aircraft can travel is provided outside the lateral direction of the aircraft. To scrape up the uncut grain culm of from above,
Since it is configured to freely revolve around the front-rear axis along the traveling direction of the machine, the grain culms are pushed out laterally outward with respect to the uncut grain culms located on the side of the traveling device. The contact point that acts changes from the lower side to the upper side, and since almost no contact is made continuously at the same point, the barley is less likely to break. In addition, the swarding rod is eccentric to the axis of the swarding rod, and the shunting rod is in contact with the uncut grass stem so as to push it strongly outward laterally as it rotates around the front and rear axis. Since the grain culm is vibrated by alternately repeating the state in which the rod retracts, rain dew attached to the grain culm is easily shaken off.

(Effect) Therefore, according to the structure of claim 1 of the present invention, the position of the shunt rod in contact with the uncut grain culms is lowered by the revolution of the shunt rod around the front-rear axis. It is possible to concentrate on a certain part of the culm of the uncut grain and prevent the pushing force from acting on the culm of the uncut grain, thereby suppressing the breakage of the stem in the middle. Also, vibration is applied to the uncut grain culm due to the intermittent lateral outward displacement of the weeding rod so that the rain dew easily swings off from the uncut grain culm, so that the grain culm can be satisfactorily maintained in a napped state. Mowing can be performed and post-treatment such as threshing treatment can be performed well.

(Operation) According to the configuration of claim 2 of the present invention, since a plurality of grass rods are arranged in different phases around the longitudinal axis, a single grass is provided. There are more opportunities to push the grain laterally outward than when the rod is revolved around the front-rear axis, and the lateral movement that the grain stem receives along with the rotation of the bait rod is increased. Intermittent displacement can also be increased per unit time, which makes it extremely easy for rain dew to drop from the grain stems.

As shown in FIG. 2, the first weeding rod 9 is moved back and forth on the fixed weeding implement support rod 8 that supports the fixed weeding implement 7 provided at the uncut side end of the pre-mowing processing unit 6. It is pivotally attached around the axis Y1 so as to be swingable. That is, the base end of the support stay 10 connected to the first dividing rod 9 is pivotally attached to the support bracket 11 of the mowing pretreatment unit 6 so as to be swingable around the front-rear axis Y1. Then, as shown in FIG. 2, a cylindrical boss 12 is loosely fitted to the rear end portion of the first dividing rod 9 made of a round bar member, and the cylindrical boss 12 is fitted to the central axis of the cylindrical boss 12. , The front ends of a pair of second shunt rods 13, 13 as a shunt rod are connected in a state in which the phase is shifted by 180 degrees. Second branch rod 13,
13 is arranged along the front-rear direction over almost the entire range from the front end to the rear end of the crawler traveling devices 1, 1. Then, the rear end portions of the second splitting rods 13, 13 are connected to each other, and the power is transmitted from the cutter driving shaft 15 of the waste straw shredding device 14 disposed behind the threshing device 3 by power branching. The mechanism 16 allows the second axis around the front-rear axis Y2.
The transmission mechanism 16 and the bevel gear mechanism are interlockingly connected to each other so as to rotate the divider rods 13 and 13 in a revolving state. The front-rear axis Y2 is set so as to substantially coincide with the central axis of the cylindrical boss 12. Further, the power transmitted through the transmission mechanism 16 causes the second branch rods 13, 13 to move.
Is set to rotate counterclockwise when viewed from the front. Further, due to the swinging of the transmission mechanism 16 around the front-rear axis center at the base end portion, the second sward rods 13 and 13 are retracted to the lateral side of the body, and the storing position is stored near the body. It is configured so that it can be switched to or from the posture and that the posture can be maintained.
