Description

[Detailed Description of the Invention] The present invention relates to a support structure for a vertical weeding device in a binder, which has good weeding performance, is simple in structure, lightweight, and inexpensive.

In order to increase the weeding effect with the uncut grain culms, when the combine harvester advances with a predetermined cutting width among the grain culms planted in the field, a weeding plate or divider is installed at the boundary between the grain culms and the uncut grain culms. Equipped with a grass rod. However, these devices may not be sufficient for grain culms that are severely lodging, and in such cases, a vertical weeding device with vertically rotating tilting tines should be installed so that it faces the uncut grain culms. There is. Among these, the binder is lightweight, runs on a single wheel, and is operated by the worker while walking, so it is preferable to equip it with a heavy object from the viewpoint of maneuverability and workability. There isn't.

This invention aims to eliminate the above-mentioned drawbacks by providing the vertical weeding device with a support structure for attaching it to the machine body as described below.

Hereinafter, specific embodiments of this invention will be described with reference to the drawings. Fig. 1 is a side view of the main part of the binder with the vertical weeding device attached, and Fig. 2 is a front view of the same, but the binder has two parts on the body with respect to the wheels 1 and 1.
The front part consists of a lifting device 3, gutter (not shown), conveyance device 4, etc., and the rear part has an engine (not shown), a transmission (not shown), It consists of an operation section (not shown), etc.

The lifting device 3 has two or three lifting cases 5
is provided on the rear upward side, and the tines 6 attached to the chain in the lifting case 5 are rotated so as to be erected on the action side, and the grain culms are raised by the tines 6.

In the case of two-row mowing as shown in FIG. 2, two raising cases 5 are provided and a weeding body 7 is interposed in the center. A substantially diamond-shaped grass divider plate 8 is provided at the lower end of the raising case 5, and a V-shaped sharp-pointed pipe divider is attached to the grass divider plate 8, which protrudes forward from the approximately central upper surface of the grass divider plate 8. The structure is such that the grass is well divided and bitten into the tines 6. The conveying device 4 consists of a grain culm leaning plate 10 on the rear side of the lifting case 5, and a conveying belt 11 with protrusions that moves along the surface of this leaning plate 10 to the binding device on the right side of the machine body 2. It plays the role of receiving the grain culms raised by the lifting tines 6 and cut by the reaping device, and sequentially transporting them to the binding device side.

On the other hand, a vertically rotating weeding device 12, which is also configured to ascend at the rear, is obliquely installed slightly outside the raising case 5 at the most side end facing the uncut grain culm group. That is, a substantially diamond-shaped grass divider plate 8 is provided at the lower end of the raising case 5, and a V-shaped sharp grass divider 13 made of a pipe is protruded from the approximately central upper surface of the grass divider plate 8. The front end of the vertical grass divider 12, that is, the central shaft extension of the grass divider 12 that connects the drive shaft 18 and the passive shaft 19, is supported and connected to the upper end of the pipe grass divider 13. 12 is supported by a conduction tube 16 that accommodates an input shaft to the vertical weeding device 12, which is an upwardly extended input shaft to the raising case 5. Then, inside the conduction tube 16, the direction of the conduction shaft is changed by 90 degrees using a bevel gear, etc.
The drive shaft 17 is made to protrude horizontally from the main body 15, and the sprocket 18 is fixed thereto.
A driven shaft 19 is also provided at the front of the shaft 5, and a sprocket 20 is fixed to this.
A chain 21 is hung between the two, and tines 22 are attached to the chain 21 at appropriate intervals.

FIG. 3 is an enlarged sectional view taken along line XX in FIG.
The main body 15 has two channels 2 facing upward and downward.
3 and 24, in which a guide bar 25 is installed to allow the chain 21 to roll, and downward pieces 2 are installed from the upper and lower channels 23 and 24, respectively.
6. The upward piece 27 is made to hang down or rise up, and is fixed with bolts 28 or the like so as to be movable up and down.

In this way, this invention has a binder in which the drive shaft 18 of the vertically rotating weeding device 12 at the front end of the device 12 is
The upper end portion of the V-shaped sharp-pointed pipe grass divider 13 protrudes forward from the upper surface of the approximately diamond-shaped grass divider 8 that extends forward from the lower end of the case 5 by raising the central axis extension that connects the drive shaft 19 and the lower end of the case 5. a transmission tube 1 that accommodates a shaft that is supported by the rear end of the shaft and that is pulled up to extend the input shaft to the case 5 upward and input to the vertical weeding device 12;
6, the following effects can be expected.

That is, from the upper surface of the substantially diamond-shaped grass dividing plate 8 extending forward from the lower end of the case 5 by pulling up the central axis extension portion of the front end of the vertically rotating grass dividing device 12 that connects the drive shaft 18 and the passive shaft 19 of the device 12. It is supported by the upper end of the V-shaped sharp pipe grass divider 13 that protrudes forward, and the rear end is pulled up to extend the input shaft to the case 5 upward and input it to the vertical weed cutting device 12. Since the shaft is raised by the conduction tube 16 that accommodates the shaft and supported by the case 5, no special member is required for fixed support. As a result, the number of members can be saved and the weight can be reduced, which satisfies the requirements of this vertical weeding device: light weight, simple structure, and low cost. In addition, it is securely fixed to support the upper and lower ends of the device.

Also, the front end of the vertical weeding device 12, the device 1
A roughly rhombic divider plate 8 extending forward from the lower end of the case 5 extends forward from the upper surface of the approximately diamond-shaped divider plate 8. Because it is supported on the upper end of the pipe-made weed divider 13, the grain culm raised by the weed divider 13 is smoothly sent to the vertical weeding device 12 by the continuous guide part, and the sent grain is After raising the culm by scooping it up from below, the tines 22 act to weed the culm while transporting it diagonally backward, resulting in even higher weeding and pulling performance.
