DETAILED DESCRIPTION OF THE INVENTION The present invention divides rushes growing in a field according to cultivation rows using weeding rods that protrude long forward and are arranged side by side on the left and right sides of the front end of the machine. Harvesting is carried out using a cutting blade device installed on the machine body located behind the grass rod, and the stock picker is installed in the front and back direction of the machine body with the receiving opening facing above the rear of the cutting blade device. In a rush harvester, which is designed to transport the grass to the rear of the machine where a pickling device, knotter, etc. This invention relates to a guiding device that guides the user to a receiving port of a clamping and conveying device.

More specifically, as shown in FIG. 4, the guiding device in the rush harvesting machine targeted in the present invention is a cutting blade device 4 that cuts the stump edge of the grass S to be weeded with the weeding rod 1. At the top, there is provided a receiving opening M for a stock clamping and conveying device a which uses the cutting blade device 4 to clamp the plant base of the grass S' whose stump edges are to be cut and transports it to the rear of the machine. In the rush harvester, above the cutting blade device 4, there is a rear extension portion 1 of the grass dividing rod 1.
a, and support the stem culm of the grass S′ whose stump edge is to be cut by the cutting blade device 4 so as to lean against it.
This is a guiding device configured to guide the stock toward the receiving port M of the stock clamping and conveying device a.

The guiding device in this type of rush harvesting machine is such that the grass S to be divided by the dividing rod 1 and cut by the cutting blade device 4 does not flow smoothly into the receiving port M of the plant clamping and conveying device a. There is a problem in that the receiving opening M of the original clamping and conveying device a becomes unable to clamp the base of the cut grass S'.

The present invention solves this problem, and the mower device 4
It is an object of the present invention to provide a new means for guiding the stem part of the cut grass S' to be reliably clamped at the starting end which is the receiving opening of the stem clamping and conveying device 4.

Therefore, the guidance device for the rush harvester according to the present invention was completed based on the knowledge obtained through various studies in order to solve the above-mentioned problems. That is, the weeding action of the weeding rod 1, the cutting action of the cutting blade device 4, and the grass to be cut by the cutting blade device 4.
When we studied the flow of S' toward the receiving port M of the stock clamping and conveying device a, we found that the rush S' to be harvested
However, due to the height of the plants, the tip side of the rush is swayed in one direction perpendicular to the cultivation row, and the tip side of the rush S in the adjacent row is stacked on top of the tip side of the rush S in one row. Igusa S in the row adjacent to the top
It is cultivated in a laid-down position so that the tips of the ears overlap. Then, rush harvesting machine produced rush S.
Harvesting is done by separating the rushes from the rows of rushes S whose tips are in the top layer, pulling them off with the weeding rod 1. When the cutting blade device 4 cuts the stump edge of the desired grass S, the culm of the desired grass S' comes into contact with the rear extension 1a of the weeding rod 1, as shown in FIG. The tip side, which has a tendency to float during weeding, is rotated downward so that it sinks under its weight, and as a result, the plant base side below the rotation fulcrum P is rotated. The rush harvester moves up and rotates in a direction perpendicular to the direction of the cultivation row, which is the direction of movement of the rush harvester, and escapes from the front of the receiving port M of the stock clamping and conveying device a to the mowed land side Y. It was found that there is a tendency to From this, from the front side of the reception opening M of the stock head clamping and conveying device a, the mowed land is placed below the rear extension portion 1a of the grass dividing rod 1 above the cutting blade device 4 of the rush harvester. The cutting edge is cut by the cutting blade device 4 at the part brought to the side Y, and the rush S' which is leaning against the rear extension 1a of the above-mentioned dividing rod 1 comes into contact with the stem part of the rush S' from the already mown side Y. When the regulating member b that restricts the movement of the base of the rush S' toward the mowed area side Y is arranged as shown in Fig. 3, the cutting edge of the rush S' is cut by the cutting blade 4.
This is because the stock head portion of S' is smoothly transferred to the receiving port of the stock head holding and conveying device a.

For this reason, in the present invention, as a means to achieve the above-mentioned object, there is a weeding rod that protrudes forward at the front end of the machine body, and the cutting edge of the grass to be weeded is cut with the weeding rod. a cutting blade device, and above the cutting blade device there is a rear extension of the grass dividing rod that supports the stem culm of the grass to be cut by the cutting blade device, and In a guide device for a rush harvester, the grass cutting rod is arranged above the cutting blade device and is provided with a receiving port for a plant clamping and conveying device that pinches and transports the grass plant base toward the rear of the machine body. The stump edge is cut by the cutting blade device at a lower part of the rear extension of the grass rod and is closer to the mown field than the rear extension of the grass rod, and the cutting edge is cut so as to lean against the rear extension of the grass rod. A guide device for a rush harvesting machine, characterized in that a regulating member is provided that comes into contact with the rush head from the mowed field side and restricts the movement of the rush base from the mowed field side. This is something I would like to raise.

Next, an example of implementation will be described in detail with reference to the drawings.

As explained above, the guidance device of the rush harvesting machine according to the present invention includes a weeding rod that protrudes forward from the front end of the machine body and a cutting blade device that uses the weeding rod to cut the edge of the grass to be weeded. Above the cutting blade device, there is a rear extension portion of the dividing rod that supports the stem culm of the grass to be cut by the cutting blade device, and a base portion of the grass to be cut by the cutting blade device. In a guidance device for a rush harvester, which is provided with a receiving port for a clamping and transporting device that clamps and transports the stock toward the rear of the machine,
The cutting edge is cut by the cutting blade device at a portion below the rear extension portion of the grass cutting rod above the cutting blade device and closer to the mowed field side than the rear extension portion of the grass cutting rod. A regulating member is disposed that comes into contact with the base of the rush leaning against the rear extension of the grass dividing rod from the already cut field side and restricts the movement of the base of the rush toward the already cut field. Since it is configured, the branching rod 1
The grass S to be divided is cut from the stump by the cutting blade device 4, and when the grass S is cut from the stump by the cutting blade device 4, the blade leans against the rear extension portion 1a of the weeding rod 1 located above the cutting blade device 4, and comes into contact with the rear extension portion 1a. When the part to be cut is set as the rotational fulcrum P and the cutting blade begins to rotate toward the uncut land side W, the cutting edge is moved toward the base side of the grass S' to be cut, as shown in Fig. 3. It is pressed by a regulating member b disposed below the rear extension part 1a of the weeding rod 1 above the device 4 and closer to the mowed field side Y, and moves so as to spring up toward the mowed field side Y. The operation is now regulated, and the rush S' is supported at two points, this regulating member b and the rear extension 1a of the dividing rod 1, and held in that position, and the rush S' is transported with the stock clamps in that position. It comes to be guided to the receiving port M of the device a. For this reason, conventionally, as shown in FIG. 4, the base of the grass S' whose stump edges are to be cut with the cutting blade device 4 has been pushed up to the mowed land side Y, and the base of the grass S′ whose stump edge is to be cut by the cutting blade device 4 has been pushed up to the side Y of the mowed land, and the base of the grass S′ whose stump edge is to be cut by the cutting blade device 4 has been pushed up to the side Y of the cut area. This was caused by the water escaping from the front of the receiving port M to the mowed land side Y.
The problem of poor grasping of the cut grass S' at the starting end of the stock clamping and conveying device a can be solved very effectively, and the stock clamping and conveying device a can smoothly and easily handle the cut grass S'. You will be able to hold it securely.
