Definitions
- the present invention relates to a safety plate impact absorbing device for mowers, in more detail, the safety plate is installed in the lower part of the mower to protect the mowing blades, the impact is applied to the safety plate as it hits the foreign matter when using the mowing blade. It relates to a safety plate shock absorbing device for preventing the safety plate is damaged or damaged due to.
- the mower is a device for removing weeds or removing large amounts of weeds with less power when working with weeds during the sacred grave.
- a mower is a power unit that rotates the mowing blades to cut large areas of weeds or vines in a short time. I can cut it.
- the blade rotates at a high speed, if it hits a hard foreign object such as a stone, it has a disadvantage such as a failure as well as injuries to workers or people around by blade fragments.
- the lawnmower safety shock absorber for the lawn mower is installed so that the shock absorbing member (4) is caught on both ends of the spring member (2), a ring-shaped coupling portion (6) at the lower end of the shock absorbing member (4)
- the hook portion 3 is formed at the upper end, and the cutout portion is formed between the coupling portion 6 and the hook portion 3.
- the mower safety plate has one of the structures to absorb the impact by being rotated slightly to the left and right by the elastic means and then restored, or to make the safety plate securely so that it does not break even under the impact.
- the shock plate is durable. In order to do this, a very thick metal plate has to be used, and thus a lot of weight has a disadvantage in that fatigue is much greater for workers.
- the present invention is installed on the lower portion of the blade to protect the blade and formed on the top of the safety plate and the upper safety plate support for supporting the blade and the upper safety plate support while supporting the safety plate It consists of a lower safety plate support to be formed on the periphery of the inner periphery of the safety plate and the upper safety plate support or the lower safety plate support and the safety plate rotation suppression means to correspond to each other, and the handle to prevent the rotation of the lower safety plate support Characterized in that it consists of a rotation preventing rod for fixing.
- the safety plate rotation inhibiting means is a plurality of elastic projections formed to be spaced apart at regular intervals through the inner circumference of the safety plate, and a plurality of the elastic projections of the safety plate to any one of the outer periphery of the upper safety plate support or lower safety plate support It is characterized in that the concave grooves are formed.
- the safety plate rotation inhibiting means is a concave groove of the safety plate in any one of a plurality of concave grooves formed in the inner periphery of the safety plate and the outer side of the upper safety plate support or lower safety plate support to correspond to the plurality of concave grooves. It characterized in that to form a plurality of elastic projections to correspond with.
- the concave grooves of the rotation suppressing means correspond to each other.
- the safety plate rotates in the direction of impact, thereby absorbing the impact and at the same time, foreign matter is bounced off to prevent damage to the blade or safety plate.
- the present invention allows the rotation of the safety plate while the rotation of the safety plate is to rotate only when the impact amount is applied, that is, the elastic limit of the elastic protrusions can be absorbed a considerable shock, and also by preventing unnecessary rotation of the safety plate Due to the ease of operation, it is a very useful invention that can minimize the failure of the mower.
- FIG. 1 is a perspective view of a safety plate shock absorber in the conventional mower.
- Figure 2 is an exploded perspective view of the safety plate shock absorber of the present invention.
- FIG. 3 is a combined perspective view of FIG. 2 excluding a blade
- Figure 4 is a sectional view for showing a safety plate anti-rotation means in the present invention.
- FIG. 5 is a reference diagram of a state in which the safety plate rotation preventing means of the present invention is mounted on the lawn mower.
- the present invention is a safety plate shock absorbing device for a lawnmower provided with a safety plate for protecting the blade is installed in the lower blade,
- Safety plate It is formed on the top of the safety plate and consists of an upper safety plate support for supporting the blade and the lower safety plate support for supporting the safety plate while being coupled to the upper safety plate support, the inner periphery of the safety plate and the upper safety plate support or lower safety plate Safety plate rotation preventing means formed on the outer circumference of the earth to correspond to each other, and a safety plate shock absorbing device for a mower characterized in that it is configured as a rotation preventing rod for fixing to the handle to prevent the rotation of the lower safety plate support.
- the present invention is installed on the lower blade 10, the safety plate 120 for protecting the blade 10 and the upper safety plate support 110 for supporting the blade 10 is formed on the safety plate 120 and It is made of a lower safety plate support 130 for supporting the safety plate 120 while being coupled to the upper safety plate support, the inner periphery of the safety plate 120 and the upper safety plate support 110 or lower safety plate support 130 Safety plate rotation suppression means to correspond to each other on the outer periphery, and the rotation preventing rod 140 for fixing to the handle (2) to prevent the rotation of the lower safety plate support 130.
- the safety plate rotation inhibiting means is a plurality of elastic protrusions 121 and the upper safety plate support 110 or lower safety plate support 130 formed on the inner circumference of the central hole ( ⁇ ⁇ ) of the safety plate 120 spaced apart by a predetermined interval.
- any one of the plurality of concave grooves 111 to correspond to the elastic protrusion 121 of the safety plate 120 is formed.
- the present invention forms a plurality of concave grooves 111 in the inner circumference of the safety plate 120 in forming the safety plate rotation suppressing means, and the outer circumference of the upper safety plate support 110 or the lower safety plate support 130
- One may be configured to form a plurality of elastic protrusions 121 to correspond to the recessed groove 111 of the safety plate 120.
- the most preferable structure in the present invention is a structure in which a plurality of concave grooves 111 are formed in the upper safety plate support 110, and a plurality of elastic protrusions 121 are formed in the safety plate 120.
- the safety plate rotation inhibiting means may be configured by the configuration of the elastic protrusion 121 and the concave groove 111 as described above, although not shown, by using a brake means using a known belt or disk method using a friction force Naturally, it can also be configured to suppress the rotation of the safety plate 120.
- the present invention when the mowing operation does not require the safety plate 120, the upper safety plate support 110 and the lower safety plate support 130 by separating the safety plate 120 to separate, again the upper safety plate support ( 110 and the lower safety plate support 130 may also be used in combination.
- the present invention is because the safety plate shock absorbing device is installed in the lawn mower, even if foreign matters bump when using the mowing blade to ensure that the safety plate shock absorbing device to absorb the shock to protect the safety plate to safely carry out the mowing operation.
