The present invention is designed and equipped with a rotary table mounted on a portable lawn mower cutter blade rotation drive shaft and the rotating housing is coupled to rotate the rotating shaft and the roller housing in double, and freely rotates in contact with the ground according to the movement of the operator to maintain a constant mowing height It supports the weight of the cutter blade and absorbs and distributes the repulsive impact shock to the ground, which reduces the impact transmitted to the operator, making it more comfortable to work with. The binding stand rotates firstly and the secondary roller enclosure rotates independently independently. By preventing rotation of the cutter blade and synchronous rotation, it prevents the roller from being thrown to prevent safety accidents. It is equipped with a guard to prevent the weeding of the upper part of the rotating roller enclosure, which is integrally built for comfortable weeding. Rotating roll designed to install balance bars to balance blades The carousel is equipped with a general orchard for lawns of different heights, so that the operator can easily replace the rollers for the work environment and the terrain. It is intended to provide a portable lawn mower safety roller configured to do so.

At present, some functions are published in the Patent Application No. 10-0727234, etc., and the prototypes on the market are mounted only on a certain machine, and there is a risk of being hit by synchronous rotation with the cutter blade rotation axis, and the roller height is specified. It is inconvenient to adjust the height according to the working environment and the terrain. In general, when weeding, we carry out the work by subjecting the portable lawn mower cutter blade to adjust the height subjectively. As there is a danger that the cutter blade hits the ground even in small carelessness, there is a difficulty that requires much technical and physical attention in order to mow using a portable mower.

This safe and functional portable lawn mower safety roller has been improved and secured so that anyone can easily install it in the optimal working environment and perform comfortable weeding work easily without installing additional equipment. It is to provide.

The portable lawn mower safety roller of the present invention is designed to protect the cutter blade fixing nut mounted on the cutter blade rotating shaft and to design the rotating table so that the binding stand and the rotating roller housing can be independently rotated 360 degrees and the balance of the cutter blade A balance bar is installed at the bottom to hold a flat surface, and at the top of the rotary roller enclosure, which is installed in a round shape, the support roller is set up inside the rotating roller enclosure, and the weight of the roller is lightened as much as possible and the binding key groove is installed on the It is easy to attach and detach, so that the worker can install the rotating roller box with the height suitable for the working environment and the terrain.The lawn is composed of 3cm for grass, 4cm for grass, 4cm for orchard, and 5cm for height. Anyone can easily install it by making the 2nd rotation to prevent the rotating roller enclosure from synchronous rotation. It intended to provide a comfortable and safe portable mowing roller that technical challenges to ensure it is safe to do the weeding.
