A guide member 8 for preventing clogging is provided slightly higher than the cutting blade 5 at a more forward portion, and a resistance member 9 for removing an obstacle is provided at the rotating shaft mounting portion 5a above the cutting blade 5.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a reaper.

[0002]

[Prior art]

 The reaper cuts crops with an upper guide plate provided above the disk-type cutting blade and extending forward of the cutting blade, and a guide rod provided below the cutting blade and extending forward of the cutting blade. It is designed to be introduced at the blade. For example, as shown in FIG. 5, black soybeans have stems branched from the ground, so that when cutting soybeans, the cutting blade 5 must be cut slightly below the ground surface. There are defoliation, grass, stone, soil, etc. on the ground surface.

[0003]

[Problems to be solved by the invention]

 In the above prior art, obstacles such as stalks, leaf fall, grass, stones, soil, etc. are often found between the cutting blade and the upper guide plate or the guide rod, and between the cutting blade and the rotating shaft mounting portion of the cutting blade during the cutting operation. Work had to be interrupted due to jamming or wrapping and these had to be removed.

[0004] The present invention has been made to solve the above-described problem, and eliminates obstacles, and at the same time, causes clogging between the cutting blade and the upper guide plate and the guide rod, and also to the rotation shaft mounting portion of the cutting blade. An object of the present invention is to provide a reaper that eliminates wrapping and improves work efficiency.

[0005]

[Means for Solving the Problems]

 Means of the present invention for solving the above-mentioned problem is a reaper equipped with a disk-type cutting blade that is driven to rotate, and a guide bar that is disposed below the cutting blade and extends forward from the cutting blade. The guide rod is provided with a guide member for preventing clogging slightly higher than the cutting blade at a portion forward of the cutting blade, and a resistance member for removing obstacles is provided at a rotation shaft mounting portion above the cutting blade. It is characterized by the following.

[0006]

[Embodiment of the invention]

 One embodiment of the present invention will be described with reference to FIGS. In the reaper, the power of the drive unit 1 is transmitted from the drive side pulley 2 to the reaping side input pulley 4 via the belt 3, and the reaping blade 5 rotates to perform the reaping operation. Above and below the cutting blade 5, an upper guide plate 6 and a guide rod 7 for guiding stalks such as soybeans to the cutting blade 5 are provided extending forward. Here, the guide bar 7 is provided on the side that is cut down in the rotation direction of the cutting blade 5. Since the above is a known structure, further description will be omitted.

The guide rod 7 is provided with a guide member 8 for preventing clogging at a position in front of the cutting blade 5 inclining toward the cutting blade 5, and a tip of the guide member 8 for preventing clogging is provided. It is slightly higher than blade 5. The rotating shaft mounting portion 5a of the cutting blade 5 is provided with an obstacle removing resistance member 9.

Therefore, when cutting soybeans, since the obstacle removing resistance member 9 is rotating together with the cutting blade 5, the obstacle removing resistance member 9 is moved before the obstacle goes to the rotating shaft mounting portion 5 a of the cutting blade 5. 9 eliminated. This prevents an obstacle from clogging or winding around the rotating shaft mounting portion 5a.

The soybeans after the stalks have been cut are turned sideways by the rotation of the upper guide plate 6 and the cutting blade 5. In this case, if the clogging prevention guide member 8 is not provided, the stem is caught between the guide rod 7 and the cutting blade 5 and the belt 3 slips due to the resistance or the engine of the drive unit 1 stops and the work can be performed. Disappears. When the clogging prevention guide member 8 is provided as shown in the present embodiment, the clogging prevention guide member 8 does not get caught between the guide rod 7 and the cutting blade 5, and the work can be performed smoothly.

The clogging prevention guide member 8 may be made of round bar steel, round pipe, square bar steel, or may be made of flat steel or iron plate as shown in FIG. Also, as shown in FIG. 4B, the same effect can be obtained if the clogging prevention guide member 8 is not inclined and is slightly higher than the cutting blade 5 even in parallel. Similarly, the obstacle removing resistance member 9 may be made of a round bar, a round pipe, a square bar, a flat bar, or an iron plate.

[0011]

[Effect of the invention]

 According to the present invention, there is provided a reaper comprising a disk-type cutting blade driven in rotation and a guide bar disposed below the cutting blade and extending forward from the cutting blade. A clogging prevention guide member is provided slightly higher than the cutting blade at a portion forward of the cutting blade, and an obstacle removing resistance member is provided at the rotation shaft mounting portion above the cutting blade. The clogging between the cutting blade and the upper guide plate and the guide rod and the winding of the cutting blade around the mounting portion of the rotating shaft are eliminated, thereby improving work efficiency.
