Abstract
Description
The present invention relates to a safety device of the mower, and more particularly to a safety device of the mower equipped with a support means to support and move the ground on the boom so that the work is not physically difficult due to the weight of the cutting unit.
Generally, mowers are used to mow grass and weeds, and are mainly used to remove oxygen weeds during sapling.
As shown in FIG. 1, the lawn mower includes an engine unit (not shown) that is worn on a shoulder; A boom connected to the engine unit and transmitting power; It is configured to include a cutting portion (c) having a
Therefore, the engine is carried on the shoulder and the
The present invention has been made to solve the above problems of the prior art, by having a support means on the boom close to the cutting portion can be cut in a state supported on the ground can reduce physical fatigue due to high weight In addition, the purpose is to provide a safety device for a mower so that the working efficiency can be improved by setting the appropriate cutting length.
An object of the present invention described above, the engine portion to be carried on the shoulder; A boom connected to the engine unit to transmit power; A cutting unit mounted to an end of the boom and having a cutting blade rotated by power; A support means mounted on the boom and supported on the ground, the support means being connected vertically to the boom by a connection member provided at an upper end thereof, the support being adjustable in length; A horizontal axis installed horizontally at right angles to the bottom of the support; It can be achieved by the safety device of the lawn mower characterized in that it comprises a wheel mounted to both ends of the horizontal axis in contact with the ground.
The connecting member is composed of semi-circular first and second rings that are engaged by the coupling of the fastener, a protrusion is formed on the inner circumferential surface of the first and second rings, the second ring is integrally on the upper end of the support And the first ring is separated.
The fastener is rotatably coupled to any one of the bolt and nut or the first and second ring, characterized in that the cam is a lever formed.
The support is composed of the first rod body and the second rod body is fitted to adjust the length, characterized in that the butterfly bolt for fixing the adjusted length is screwed to the upper outer peripheral surface of the second rod body.
The support is characterized in that the protection net is attached to block the splashing of stones or foreign matter.
According to the present invention, by providing the support means on the boom close to the cutting portion, the cutting work can be carried out while being supported on the ground, thereby reducing physical fatigue due to high weight, and setting an appropriate cutting length, thereby improving work efficiency. There is an effect that can be. In addition, the gap between the ground and the cutting blade can be kept constant so that the cutting blade does not touch the ground, so cutting the mowing to a certain length can not only cut neatly, but also the possibility that the cutting blade will touch the ground due to the accumulation of fatigue of the worker is extremely Less accidents can be less, and can prevent collision with small stones can prevent accidents.
