Description

[Detailed Description of the Invention] The present invention relates to an agricultural implement that can efficiently harvest grains such as beans.

Conventionally, as a machine for reaping soybeans, beans, etc., the stalks of soybeans, etc. are cut with a front cutter located on the center line in front of the moving mobile agricultural machine, and the worker and the mobile agricultural machine move from behind. Therefore, there is a risk of stepping on the cut stems, etc., and there is a risk of the grains falling off. Therefore, it is difficult to perform efficient cutting with less shedding. Therefore, a discharge mechanism and a conveyance mechanism for discharging the cut stems etc. to the rear and sides are required, which complicates the structure and increases the cost.

The inventor of the present invention took into consideration the above-mentioned problems of conventional reaping working machines used for beans and the like, and devised the present invention in order to improve these problems.

The object of the present invention is to extend a frame to the front of a mobile agricultural machine body such as a tiller body, attach a pair of stem guide members to the sides of the frame, and widen the interval between the guide members at the front. The guide members are designed to gradually narrow toward the rear, and the space between the guide members is open at the rear, and a reaping cutter is attached so as to overlap with the rear part of the guide member, so that when the main body moves forward, the stems, etc. can be spun between the guide members. Gather the stems together, cut them with a cutter, and expel the stems from the opening to the rear and side.
To provide an agricultural working machine which discharges stems laterally and rearward without requiring a discharge mechanism or a conveyance mechanism, performs efficient cutting work with a simple structure, and prevents grain shedding.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
