Description

[Detailed description of the invention] This invention is equipped with a slanted dividing rod located at a higher level toward the rear end on the lateral outer side of the stem culm pulling device so that it can be driven and oscillated around a fulcrum on the tip side. The purpose is to modify the weeding device of the reaping harvester so that the weeding of the reaped and non-reaped stem culms is performed extremely well, regardless of the planting status or properties of the stem culms. .

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

As shown in FIGS. 1 and 2, a fixed weeding tool 1 that divides the planted grass into objects to be cut and objects not to be cut, a pair of left and right spiral rotating bodies 2a and 2b that cause the grass to be cut to be cut, The first step is to remove the straw that is being harvested while it is being pulled up.
and a reaping pre-treatment section having a device for separating the non-reaping grass with second weeding rods 3 and 4, and a device 5 for pulling up and reaping the grass, both spiral rotating bodies 2a for lifting and transporting the tip of the ear, By cooperation between the rear end side part 2b and a pair of left and right endless rotating bands 6a and 6b that lift and transport the plant side to the rear of the machine, the harvested straw grass is lifted and conveyed, and the ear side is located at the front, and , a vertical conveyance section in which the culm is placed in a laid-down position along the longitudinal direction of the aircraft, and the strawberry from this vertical conveyance section is transferred to two endless rotating bands 7, 8 with locking claws and a pair of upper and lower endless rotating bands 9a, 9b. A lateral conveying section that conveys the grass to one side of the machine in cooperation with the lateral conveying section, from which the short culm grass that is not held by the endless rotating belts 9a and 9b is transferred to the rear of the machine by the endless rotating belt 10. A sorting section that selects and releases the selected straw grass by dropping it to one side of the machine body by a chute 11, a container 12 that collects and stores long culm grass of a set length or more from the horizontal conveyance section, and a traveling wheel 13, A self-propelled body having an engine 14, a control handle 15, etc. is equipped to constitute a straw harvester.

To configure the weeding device, FIGS. 1 to 3 are shown.
As shown in the figure, each of the first and second branching rods 3 and 4 is arranged on the lateral outer side of the left helical rotating body 2a in an inclined posture such that the rear end thereof is located at a higher level. The tip side of each of the weeding rods 3 and 4 is connected to the weeding tool attachment 17 via a ball joint 16, so that each of the weeding rods 3 and 4 can be swung around a fulcrum on the tip side. Then, a rod 18a or 18 is provided on the free end side of each of the dividing rods 3 and 4.
The weeding rod drive arm 19 connected via b,
It is swingably attached to a support 20 extending from the fuselage body by a pivot shaft 21, and is thereby attached to a drive wheel body 23 which is interlocked with the drive rotation shaft of the left helical rotary body 2a via a transmission case 22. The rods 24 are interlocked and connected so as to be driven in a reciprocating manner, and when the first dividing rod 3 is displaced toward the spiral rotating body 2a, the second dividing rod 4 is upwardly displaced. 3 to the left and right and the second weeding rod 4 up and down. While the second dividing rod 4 pushes up the non-reapable grass B and separates it from the non-reapable grass A, while 3 separates the tip of the grass A to be reaped to make it easier to separate it from the non-reapable grass B. This ensures that the weeding is performed without breaking or tearing the cul.

In configuring the drive mechanism 25, when there is almost no tangling of the ears, the first weeding rod 3 is connected to the helical rotating body 2.
If both dividing rods 3 and 4 are driven in a synchronized state in which the second dividing rod 4 is displaced upward when the second dividing rod 4 is displaced to the side opposite to a, as shown in FIG. The stock side is connected to the spiral rotating body 2 by the first dividing rod 3.
The tip side is pushed up by the second weeding rod 4 while being pushed laterally outward of a, and weeding is carried out extremely reliably even with extremely long stem culms. In short, the driving timing of the bifurcation rods 3 and 4 may be variously changed depending on the planting status and properties of the rush.

Instead of the helical rotating body 2a, a lifting configuration may be adopted in which the locking pawl is moved upward by an endless rotating body, and these are collectively referred to as a lifting device 2a.

The above-mentioned weeding device can also be applied to a harvester that harvests various stems and culms of rice, wheat, etc. other than straw grass.

In summary, the weeding device of the reaping/harvesting machine according to the present invention has first and second weeding devices in an inclined position that are located on the lateral outer side of the stem culm pulling device 2a and are located at a higher level toward the rear end.
A mechanism 25 in which the grass dividing rods 3 and 4 are provided to be swingable around a fulcrum on the tip side, and drives and swings the first grass dividing rod 3 left and right and the second grass dividing rod 4 up and down, respectively. It is characterized by having the following.

In other words, since there are two dividing rods, the first dividing rod 3 that can be driven and moved horizontally and the second dividing rod 4 that can be driven and moved up and down, for example, when the tip of the stem culm is severely entangled, In order to achieve this, both the dividing rods 3 and 4 are driven in a synchronized state in which the second dividing rod 4 is displaced upward when the first dividing rod 3 is displaced toward the pulling device, as shown in Fig. 4. While the first weeding rod 3 separates the tip side of the stalk culm to be reaped to make it easier to separate the stalk culm to be reaped and the stalk culm not to be reaped, the second weeding rod 4 separates the stalk culm to be reaped. Since the stem culm is pushed up and separated from the stem culm to be harvested, weeding is reliably carried out without breaking the culm or tearing off the tips.Also, when there is almost no entanglement of the tips, the first weeding rod By driving both grass dividing rods 3 and 4 in a synchronized state in which the second grass dividing rod 4 moves upward when the grass dividing rod 3 is displaced away from the pulling device 2a, as shown in FIG. While the base side of the stem culm is pushed outward to the lateral side of the pulling device 2a by the first splitting rod 3, the tip side of the stem is pushed up by the second splitting rod 4.
Even with extremely long stem culms, weeding can be done extremely reliably. Therefore, regardless of the planting status and properties of the stem culm, the two-branched stem 3,
By adjusting the drive timing in step 4, the weeding of the stem culms to be harvested and the stems not to be harvested can be done more reliably while avoiding damage to the stem culms than in the past where only one dividing rod was provided. Now I can do it.
