DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reaper, and more particularly to an agricultural machine tool for a human to manually harvest rice and wheat stalks when harvesting crops for stalking rice and wheat. The purpose of the present invention is to cut a corner of a field to secure a place for a combine to enter the field, and to use the field in a narrow place or a narrow field where harvesting using the combine is difficult.

[0002]

2. Description of the Related Art Modern agriculture is highly mechanized, and the number of manual operations is reduced. For example, in rice cultivation, mechanical devices are used in almost all processes from rice planting to harvesting. Therefore, when harvesting for harvesting, it is common to harvest using a combine.

However, in order for the combine to enter the rice field, the rice at least at the initial entry point and at the place where the combine rotates (usually at the four corners) must be harvested manually in advance. Such preliminary mowing was done manually, as in the past, with the hips bent down manually.
That is, the rice and wheat stalks are cut from the plant while holding the sickle and bending down.

[0004] It is also true that modern agriculture is highly mechanized, but at the same time, there is a considerable number of cultivated lands such as narrow rice fields and mountainous areas where mechanization is impossible, ie, rice transplanters and combine harvesters cannot enter. It is also true that it exists.
In such a narrow rice field, all operations are performed manually. Therefore, when harvesting rice and wheat, it is necessary to hold the sickle and harvest the rice and wheat stalks manually.

[0005]

However, even though the area of each field is small, if the number of fields is large, the harvesting operation by human power is performed by bending down the waist, and the physical fatigue of the worker is increased. At present, it is severe and the work efficiency is reduced, which is the bottleneck of modern mechanized agriculture.

Accordingly, an object of the present invention is to provide a machine which can easily and easily cut rice, wheat, etc., which need to be cut by hand, with a low degree of physical fatigue.

[0007]

According to the present invention, a boat is fixed to a lower end portion of a rod having a predetermined length, a front portion thereof is opened, and a center of a bottom portion of the boat body is provided. Forming a notch that opens forward, fixing a saw blade to at least one of the notches, and providing a weeding frame that guides a stalk of rice or wheat to the saw blade at the front of the boat body, A structure in which a stem rod gripping frame is rotatably supported on one side of the boat body behind the weeding frame and a lever for rotating the stem rod gripping frame is fixed to a substantially intermediate portion of the rod body. provide. Further, the saw blade portion is fixed to face the notch portion and is formed in an arc shape bulging toward the opposite side, and a stem rod receiving frame is provided on a boat body behind the stem rod gripping frame. A configuration in which both ends are connected near the base of the weeding frame, and a stem-rod upright frame is provided which rises at a predetermined height in a substantially U-shape toward the rear and a handle portion is formed at an upper end portion of the rod body. And a configuration in which the stem-and-rod gripping frame and the lever are connected by a wire cable.

[0008]

According to the present invention having the above-described structure, when the handle is held and the boat body is strongly pushed toward the rice plant or the barley through the rod in the upright position, the rice or wheat stem and rod are inserted into the notch. Is guided,
It is cut by the saw blade, placed on the inner bottom of the boat body, and held substantially vertically in the upright position by the stem-rod receiving frame and the stem-rod standing frame.
Therefore, when the lever is gripped, the stem-and-rod grip frame rotates and can be held and transported on the boat so that the stem-and-rod does not fall off, and when the lever is released at the transfer destination, the stem and rod are released from the constraint. To be free from the hull. Therefore, the harvested rice plant, wheat plant, etc. can be grasped (held) by the reaper in a state of being stood up by a fixed amount, and the reaper can be transferred as it is using the reaper. it can. In addition, the work can be performed by the push-cutting operation while standing, and the hand-held operation of the reaper can be performed while the transfer operation is standing. In addition, it is possible to guide the rice plant, the wheat plant, and the like to the reaper, and it is possible to properly handle those that are guided to the reaper and those that are not.
