Description

Buff type snowplow for pay loader}

The present invention relates to a snow plow that is attached to a pay loader exclusively and quickly removes snowfall and snowfall in winter. More specifically, a three-stage separation in the width direction and a two-stage lower snow removal at the same time Only the lower snow removing plate at the site where it collides with an obstacle during snow removal by the plate is lifted up by itself, absorbing the shock, so that the dilting operation is smooth and the vibration generated by the load of the snow removing plate when descending can be drastically reduced. A buffered snow plow for a payloader.

Most snow plows are usually attached to winter vehicles and used for a limited time. Sometimes, they are attached to special equipment such as tractors or small motorcycles, such as Utility Model Registration No. 243322 or 243467, filed by the inventors. It's all done.

However, since most snow plows must be attached to a vehicle, related organizations such as local governments and national road maintenance construction offices attach them to trucks used for transportation purposes and use them for a limited time in winter. It was not available. Therefore, in order to solve this problem, a dedicated truck that can be used by attaching a snow plow must be supplied, but a problem that requires a lot of budget is caused.

In contrast to the trucks described above, pay loaders in each engine were almost unused in winter, which was undesirable in terms of equipment efficiency.

On the other hand, the conventional snow removing machine is provided with a buffer means for mitigating the impact on the rear of the snow removal plate essentially to prevent damage caused by an obstacle to the snow removal plate during the snow removal operation, the buffer means is a life of the snow removal machine. It is a very important structure that influences many studies and efforts on the buffer means.

Such research and efforts have been suggested by the inventors of the present invention in various ways such as "Registration Patent No. 305920, Registration Utility Model No. 243304."

When looking at the prior art, the pre-registered patent of the former is to remove the snow by relieving the impact by rotating only the snow blades of the site that collides with the obstacles when the snow blades are separated into a plurality of pivots installed on the bottom of the snow removal plate As the entire plate and snow blade are rotated to the rear, the entire snow removal plate falls to the front when restored by its own heavy load, and thus it is a useful invention that can prevent damage to the vehicle, snow removal plate, and snow blade.

In addition, the latter pre-registration devises the snow removal plate and the snow blade in three steps in the width direction, so that only the snow removal plate and the snow removal edge of the area that collides with the obstacle are raised, thereby alleviating the impact. The operation was very smooth compared to the cushioning shock.

However, although the above prior arts are useful, some improvements are pointed out. In the former case, the snow blades are not installed vertically but are inclined forward and downward so as to more effectively spread snow. It was easily damaged by the impact of the contact. In order to solve this problem, the snow blade should be positioned to secure enough rotation radius (the snow blade is slightly raised from the ground in the vertical state), but in this case, the gap between the snow blade and the ground becomes large, which causes the problem of snow removal not being made smoothly. It was becoming.

In the latter case, even if the snow removal plate and the snow removal section of the impacted portion of the three-stage separated snow removal plate alone does not rise during the collision, the dilting operation (upper and lower operation) is performed by the load of the snow removal plate. Not only smooth but severe vibration is generated as the vibration accumulates, the cracks are generated throughout the snow removal plate to shorten the life of the equipment, as well as the vibration is transmitted to the driver to cause the driver's fatigue.

On the other hand, the snow blade used in the conventional snow removing machine is formed of a rubber material, so that it is easily worn when used for a long period of time, it was a high cost to maintain and repair it.

The present invention is to actively solve the problems caused by the prior art, to be able to use a snow plow selectively mounted on the payloader disposed in each relevant engine, the snow plow is a top, bottom 2 The lower snow removing plate and the snow removing blade of the collided part are lifted only from the lower snow removing plate which is separated in three stages in the width direction, so that the upper and lower dilating operation is very smooth. The main purpose of the invention is to enable a prolonged lifespan.

The present invention for achieving the desired object is coupled to the horizontal frame attached to the front of the mounting frame so that the snowplow is horizontally rotated via a rotating shaft, and the top of the shovel mounting means installed on the payloader on the upper and lower link holders at both ends of the mounting frame. Snow plow mounting means for connecting the lower link;

Hereinafter, the configuration of a more preferred embodiment for effectively achieving the object of the present invention will be described.

The present invention is to allow snow removal operations to be carried out by using payloads distributed to local governments and national road maintenance offices, which are the competent authorities in charge of snow removal in winter, and the bucket connected to the payloader (1) is removed. After using the snow plow mounting means 10, the snow plow 2 can be mounted and used in a simple manner, and in the case of a collision with an obstacle during snow removal, three stages are separated in the width direction, and a plurality of two stages are separated into upper and lower stages. As only the lower snow removing plate 30 of the colliding part of the lower snow removing plate 30 is lifted alone, the dilting operation is very smooth and smooth, and it can drastically reduce the occurrence of cracks due to the vibration and vibration generated during the dilting operation. It is a characteristic gist of the invention.

The present invention for achieving the above-described characteristic gist will be described in more detail.

First of all, the snowplow 2 of the present invention has a payload 1 provided with a shovel for shoveling soil, sand, gravel or the like in front, and detaches the shovel from the shovel mounting means 3 for mounting the shovel. After that, the shovel mounting means 3 may be selectively mounted and used as a snow plow. The shovel mounting means 3 rotates up and down according to the operation of the lifter cylinder 4 in front of the payloader 1. A lower link 5 for selectively raising and lowering the shovel is installed, and the lower link 5 pushes or pulls the upper link 7 connected to the upper part while rotating back and forth according to the operation of the angle adjustment cylinder 6. It consists of a configuration in which the rotating plate 8 for controlling the rotation angle of the bucket.

The snowplow mounting means 10 of the present invention, which is connected to the shovel mounting means 3 and supports the snowplow 2 so as to rotate horizontally, has an upper and lower front surfaces of the mounting frame 11 having a rectangular shape. A pair of horizontal frames 12 are integrally attached to each other at regular intervals.

Horizontal frame 12 is a portion that is connected to the snowplow 2, the rotating end portion 13 is formed integrally with a bearing in the front for ease of rotation, the rotating end 13 has a rotating shaft 14 Snowthrower 2 is coupled to the horizontal rotation.

A pair of link holders 15 for connecting with the shovel mounting means 3 are integrally attached to both ends of the rear surface of the mounting frame 11, and above and below the link holder 15 of the shovel mounting means 3. A plurality of rotary supports 16 are formed to connect the upper and lower links 7 and 5, respectively, and the snow plow 2 is formed at the front lower end of the link holder 15 due to excessive rotation during horizontal rotation of the snow plow 2. ) Is provided with a pair of stoppers 17 to prevent breakage.

Therefore, the stopper 17 is in close contact with the elastic member attached to the main frame 2a of the snow plow 2 during excessive rotation, and no further rotation is performed, so that the snow plow 2 and the snow plow mounting means 10 Prevent collisions.

In addition, between the horizontal frame 12, a cylinder bracket 18a to which a pair of rotation cylinders 18 for fixing the snow plow 2 in the horizontal direction by a predetermined angle is fixedly attached.

The upper snow removing plate 20, which is installed in a fixed state on the front of the snow removing machine 2, has a curved shape, and a recessed surface 21 into which an upper end of the lower snow removing plate 30 is fitted is formed at a lower end thereof, A rotating shaft mounting bracket 22 is installed at the center, and a horizontal frame is connected to the rotating shaft 14 by integrally fastening the connecting bracket 23 having the rotating shaft 14 vertically formed therein. Rotating end 13 of 12 can be fitted.

The reason why the indentation surface 21 is formed at the lower end of the upper snow removing plate 20 is that the upper and lower snow removing plate ( This is to prevent the leakage of the snow to the rear of the upper, lower snow removal plate (20) (30) during the snow removal work by eliminating the gap between the 20) (30).

While the upper snow removing plate 20 is in a fixed state, the lower snow removing plate 30 which is operated up and down at the time of an obstacle collision at the lower portion of the upper snow removing plate 20 is separated from the upper snow removing plate 20. To be installed, it is installed to be separated in three steps in the width direction so as to absorb the impact only impact in the event of an obstacle collision, each of the lower snow removing plate 30 is fastened to the snow removing blade 31 by using a fastener.

The snow blade 31 is a special steel of high strength with a low breakage rate to solve the problem that the conventional snow blade 31 is made of a rubber material and is easily worn when used for a long time, it takes a lot of maintenance cost to replace or repair it It is produced using.

The upper and lower snowplows 20 and 30 are connected to each other by using a pair of drive levers 41 and driven levers 42 in an integrated structure, and at the same time, only the lower snowplows 30 are raised alone during an obstacle collision. The double lever mechanism 40 for absorbing shock is provided with a plurality of upper reinforcing plates 25 extending downward from the upper snow removing plate 20 at the rear of the upper snow removing plate 20, and the upper reinforcing member A plurality of lower reinforcing plates 35 are installed at the rear of the lower snow removing plate 30 so as to correspond to the plate 25.

The upper and lower reinforcing plates 25 and 35 are connected to each other by four points supported by a pair of drive levers 41 and driven levers 42, and spring brackets 43 are provided at the rear of the driven levers 42. The spring bracket 43 is connected to the upper snow removing plate 20 and the buffer spring 44 so that the lower snow removing plate 30 can be restored to its original state after absorbing the shock while maintaining a constant repulsive force when the lower snow removing plate 30 is raised. Provide resilience.

Here, the driving lever 41 and the driven lever 42 are connected to the rotary support 26 and 36 installed on the upper and lower reinforcing plates 25 and 35 as shown in FIG. Rotatingly coupled, in particular, the driven lever 42 is installed to be more inclined forward downward than the drive lever 41, so that when the obstacle collides with the drive lever 41 while rotating the upper snow removal plate 30 at the same time. Although the upper snow removing plate 20 is raised by the role of pushing to the upper to prevent the collision directly with the upper snow removing plate 20 there is no fear of damage.

That is, the lower snow removing plate 30 does not collide with the upper snow removing plate 20 as the lower snow removing plate 30 is raised by drawing a parabolic upward upward rather than being vertically raised by the double lever mechanism 40. Will be blocked.

The process of mounting the snowplow 2 of the present invention having such a configuration to the payloader 1 and the shock absorbing process when it is hit by an obstacle during snow removal will be described.

First of all, in order to mount the snowplow 2 of the present invention, the bucket is separated from the payloader 1, and then the upper and lower portions of the shovel mounting means 3 on the upper and lower rotary supports 16 of the link holder 15. Links 7 and 5 are respectively connected to control the snowplow 2 according to the drive of the payloader 1.

In other words, it is possible to maximize the efficiency of the equipment by performing the snow removal operation by mounting the snowplow 2 in the payloader (1) of the winter operation in a simple manner.

In addition, when an obstacle collides with the lower snow removing plate 30 during the snow removing operation, only the lower snow removing plate 30 having a relatively low self-load is lifted by itself, so that the upper and lower dilating operation is very smooth and effective. The vibration generated at the time is very low, which ensures the durability of the equipment and also provides comfortable operation because vibration is not transmitted to the worker.

The present invention can be used by selectively mounting a snow plow on the payloader disposed in each relevant organization, the efficiency of the equipment is excellent, and it is possible to reduce the cost of having a separate dedicated truck for mounting the snow plow.

In addition, the upper and lower two-stage separation and the three-stage separation in the width direction in the event of an impact during snow removal, only the lower snow removal plate of the impacted portion of the lower snow removal plate is raised alone, so the upper and lower dilating operation is very smooth And due to the lowering of the cracking rate can be improved durability of the equipment, there is an effect of providing a comfortable operation to the driver.
