In addition, in a shovel made of a shovel and a blade, the lower end, which is the opposite part of the upper end of the blade contacting the shovel, is cut at regular intervals and bent roundly to the rear, and the bottom portions are interlocked and bent to form a sharp tip. Characterized in that comprises a.

The gravel shovel according to the present invention can be used to purchase cheaply by lowering the production cost by producing a large amount of high-quality products through the press working, and easy to work when digging or moving the gravel and significantly shortening the working time It is effective.

The gravel shovel according to the present invention, in the shovel made of a shovel and a blade, the cutting edge and the end inserted into each of the cut portion rounded backwards by cutting the lower end portion at a predetermined interval, which is the opposite portion of the blade top portion in contact with the shovel The part is characterized by including a sharp bar.

Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

1 is a plan view of a conventional shovel, FIG. 2 is a plan view of a gravel shovel processing step according to the present invention, Figure 3 is a plan view of one embodiment according to the present invention, Figure 4 shows a plan view of another embodiment according to the present invention. .

Hereinafter, an embodiment according to the present invention will be described with reference to FIG. 3.

1 and 2, in order to manufacture the gravel shovel according to the present invention, the side surface of the lower end of the blade 20 is removed from the conventional shovel, and the lower end of the remaining blade 20 is cut at regular intervals.

Next, as shown in FIG. 3, the cut blade is rounded backwards to form the cut portion 30. At this time, by inserting and bending the iron bar 40 to each cut portion 30, the iron bar 40 is entered into each cut portion 30, the end of the cut bar 40 is a point 30 is formed to be easy to gravel There is an advantage that can be easily dug up the gravel.

The iron bar 40 used here is an iron bar 40 of about 70-80 HRB when it is represented by the index indicating the hardness of S-45. This S-45 iron is HRC-55 when heat treated, but can be made stronger than this, but this is appropriate because it is broken when heat treated harder.

The process as shown in Figures 2 and 3 is made through a press process, the mold for inserting the iron bar 40 at intervals when the press mold is made to meet the specifications in advance and the press when wrapping the iron bar 40 The process of cutting the blade at regular intervals and simultaneously wrapping the blade by pressing with is included.

And when forming the cut portion 30, the cut portion 30 surrounding the iron bar 40 is not all the cut surface wraps around the iron bar 40, but rather to leave a portion of the upper end of the cut portion 30 so that each cut portion ( 30) It should be smoothly connected. So that the connection portion of the cutting portion 30 and the blade 20 of the gravel shovel wrapped around the iron bar 40 can be prevented from bending or breaking.

Figure 3a is a front view of the gravel shovel, Figure 3b is a view showing the back of the gravel shovel is a view 70 is a view showing that smoothly between each cut portion 30 of Figure 3a. In addition, as shown in Figure 3b it can be seen that a portion of the top remains when the cut 30 rounded back.

In addition, as shown in FIG. 3, a protrusion 50 protruding upwardly is formed at the center of the cutting part 30 so that the protrusion 50 extends up to the blade 20 so that the blade 20 and the cutting part 30 are formed. ) Will not bend or bend. This is to increase the moment of inertia of the blade 20 and the cutting unit 30 by making the blade in a convex shape so as to prepare for the impact generated during the process of carrying out gravel.

As shown in FIG. 3, the cutting unit 30 and the iron bar 40 may be coupled by the coupling unit 60. In this case, those that can be used as the coupling means 60 will be welded or riveted bolts, etc., but is not particularly limited thereto. However, it is preferable that the rivet is most suitable.

In case of welding, it is done by hand as mentioned in the background art, which leads to the problem of delayed time and high unit cost in mass production. In case of using bolts, screw grooves are processed separately or they are separately joined using nuts. Because it has to be a lot of hands go and the production period becomes a problem. Therefore, rivets are used to facilitate mass production.

The reason for combining the cutting part 30 and the iron bar 40 by the rivet is that the gravel and the coupling part of the cutting part 30 and the iron bar 40 are constantly bumped in the process of spreading the gravel and these parts are worn out by friction. Since the iron bar 40 may fall out of the cutting unit 30, the gravel shovel may be used for a longer time.

The adoption of the coupling means 60 as described above can be manufactured according to the user's requirements, and can be manufactured without adopting the coupling means 60 in order to look more beautiful, even in this case gravel shovel Assuming eight hours of work each day, more than two years is enough. On the other hand, when shoveling gravel with a commercially available shovel, eight shovels are consumed every day, four shovels are consumed per year.

Hereinafter, another embodiment according to the present invention will be described with reference to FIG. 4.

Gravel shovel according to Figure 3 is characterized in that the weight of the gravel shovel is heavy because the iron bar 40 is coupled to each cutting portion 30. Therefore, another embodiment will be described below to make the gravel shovel lighter.

First, as shown in FIGS. 1 and 2, a side of the lower end of the blade 20 is removed from the conventional shovel by a predetermined portion, and the lower end of the remaining blade 20 is cut at regular intervals. Then, as shown in FIG. 4, each cut portion is bent roundly to the rear, and the bottom portion is bent to form a cutting portion 30 so as to be bent with each other.

In this case, the shape of the end of the cutting part 30 or the shape of the end of the iron bar 40 are the same, so that the pebbles can be easily swung in between the gravel to easily spread the gravel, and eventually the weight of the gravel shovel as much as the weight of the iron bar 40. There is an effect that can be reduced.

In addition, as shown in FIG. 4, when forming the cutouts 30, the cutouts 30 are not bent rounded back, but rather bent roundly to leave the upper portion, so that the cuts 30 are smoothly formed between the cutouts 30. Should be built. This can prevent the connection between the cutting portion 30 and the blade 20 of the gravel shovel bent or broken.

Figure 4a is a front view of the gravel shovel, Figure 4b is a view showing the back of the gravel shovel 4 is a view showing that the number 70 is smoothly connected between the cut portions 30. In addition, as shown in Figure 4b it can be easily seen that a portion of the top remains when the cut 30 is bent back round.

In addition, as shown in FIG. 4, a protrusion 50 protruding upward is formed at the center of the cutting part 30, so that the protrusion 50 extends to the blade 20 so that the blade 20 and the cutting part 30 are formed. ) Will not bend or bend. This is to increase the moment of inertia of the blade 20 and the cutting unit 30 by making the blade in a convex shape so as to prepare for the impact generated during the process of carrying out gravel.

This process is made through a press process as described above.

Therefore, when the gravel shovel is manufactured as in the above-described embodiment, the weight is lighter than the general flat shovel that is usually sold, and the work of spreading the gravel becomes easier.

The present invention has been described above with reference to one embodiment shown in the drawings, but this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom. .

Therefore, various substitutions, modifications, and changes may be made without departing from the spirit and scope of the present invention, which is not limited to the above-described embodiments and drawings.
