2. Description of the Related Art In a portable mowing machine used today, a rotary cutting blade (3) is simply rotated by an engine via a rotary shaft inside a rotary transmission rod (4) to cut grass. Is what it is. In this case, when the rotary cutting blade (3) hits the waterproof wall provided on the ridge of the paddy field, the waterproof wall is damaged, and the water applied to the paddy field leaks, and does not fulfill its role. In many cases, plastic (polyvinyl chloride) corrugated sheet or waterproof sheet is installed on the waterproof wall. During mowing work, the rotary cutting blade (3) easily breaks, and repair is very troublesome. In the worst cases, they could not be used for many years, resulting in disposal and adverse economic and environmental consequences. or,
For the protection of the rotary cutting blade (3), see, for example, JP-A-7-194.
225 and Japanese Patent Application Laid-Open No. H10-117550, which seem to be effective in protecting the rotary cutting blade (3), however, entanglement of grass during use, foreign matter, especially string-like material, etc. When entangled, the work was interrupted each time, disassembly and cleaning was required, and disassembly and cleaning were very troublesome and troublesome.

There is a method of spraying a herbicide or the like on the furrow to prevent the growth of grass and to eliminate the necessity of mowing. The roots of the weeds work to prevent and reinforce the collapse of the ridges, so even if troublesome, weeds grow on the ridges, and several mowing operations are required before harvesting. Also, there are holes in the ridges due to moles, so it is essential to install a waterproof wall. Under such circumstances, protective equipment for portable mowers to prevent damage to the waterproof walls of the ridges is still on the market. There has been a demand for a simple and inexpensive protective device for a portable mower that reduces the entanglement of cut grass and that is easy to disassemble and clean.

A mowing portable portable mower characterized by preventing a breakage of a ridge waterproof wall or the like in which a support rod (1) is attached with a nut (6) and a protective plate (2) is attached to a tip thereof with a protective plate mounting screw / nut (7). A protective attachment for the machine is provided. Here, the protection plate (2) is provided with a chamfered portion (9) within a horizontal plane tip angle of 90 degrees or less to prevent resistance of the mower from moving forward and backward, and at the same time, the width of the horizontal portion of the protection plate (2). Is provided to prevent the protection plate (2) from moving toward the seam of the waterproof wall. Also, when the mower was started with the engine and the choke was being pulled, the rotary cutting blade (3) was rotating at the same time, and there was a danger that the soil and stones would be scattered. By floating the rotary cutting blade (3),
The danger can be avoided, and the effect of the secondary protective plate (2) is further exhibited.

The operation and effect of the present invention is to cut the vegetation by rotating the rotary cutting blade (3) via the rotary transmission rod (4) by the rotation of the engine and usually moving the cutting blade to the left and right. By providing the protection plate (2), the protection plate (2) is placed in parallel to the waterproof wall provided on the paddy field ridges, etc., and the rotary cutting blade (3) is moved back and forth without damaging the waterproof wall. You can mow vegetation. It is also effective in places other than the waterproof wall (stone wall, wire mesh, tree plant, etc.), and also protects the rotary cutting blade (3). The protection plate (2) can be moved up, down, left and right by means of a mounting auxiliary bracket (5) for mounting on the support rod (1), an auxiliary bracket mounting adjusting screw / nut (6), and a protrusion width adjusting groove (10). Even if the size changes depending on the type of the rotary cutting blade (3), it can be adjusted, and since the protective plate (2) is located above the rotary cutting blade (3), the rotary cutting blade (3) It is very easy to replace and clean. Furthermore, when the engine is started by the protection plate (2), the rotary cutting blade (3)
Since it can be installed so that it does not touch the ground, it can be started safely. The protection plate (2) has a horizontal tip with an angle of 9 degrees.
By providing the chamfered portion (9) within 0 degree, it prevents resistance of the mower from moving forward and backward, and at the same time, by providing the width of the horizontal portion of the protective plate (2), the protective plate ( It has the role of preventing the misstep 2). With such a configuration,
It is a simpler and simpler protector for the ridge mower than the conventional rotary cutting blade (3) protector, and has a very large effect.
