Description

Magnetic force generating bucket}

The present invention relates to a bucket mounted on an excavator. More specifically, an electronic chuck is mounted on the bucket itself, and by outputting magnetic force when necessary, various hardware generated during work can be adsorbed and easily collected. It relates to a magnetic force output type bucket.

Excavators, commonly called excavators, are used for various civil engineering, construction, or demolition work, such as excavation work to dig up the ground, loading work to load soil onto a dump truck, crushing work to dismantle a building, grading work to prepare the ground, etc. It is an important field equipment that is essential.

The basic structure of an excavator includes a main body equipped with an engine, a rotating part mounted on the main body, a cab located on the side of the turning part, a boom connected to the turning part, an arm connected to the boom, and a bucket mounted on the end of the arm. has

In addition to the bucket, various attachments can be connected to the arm. For example, various mounting equipment such as crusher, hammer, breaker, shear, tongs, electronic chuck, etc. can be selected and used. The various attachments mentioned above are fixed to the arm and operate by hydraulic pressure output from the hydraulic source or power source of the excavator.

Meanwhile, buckets are often used when demolishing buildings or structures. Buckets can easily contain waste materials such as concrete shreds or brick fragments and load them onto, say, a waiting removal truck. However, waste also includes a lot of rebar and other iron waste of a size that cannot be contained in a bucket, and these are difficult to dispose of with a bucket. In order to dispose of steel waste, the bucket must be removed from the boom and an electronic chuck must be installed in its place, but this work is cumbersome and time-consuming, which causes the work time to be extended.

As a background technology for this related invention, an excavator bucket equipped with an electromagnet has been disclosed through Domestic Public Utility Model Publication No. 20-2010-0009055.

The disclosed excavator bucket is a bucket that is rotatably connected to the end of an arm unit that is coupled to the excavator body and rotates, and has an opening formed to perform excavation work, and includes a rotation pin and a rotation pin bracket coupled to allow the bucket and the arm unit to rotate. An electromagnet unit is fixedly attached to the outer surface of the bottom of the rotating fixing pin to form a magnetic field in the bucket itself by an electromagnet to lift a metallic object. The electromagnet unit is sealed in an electromagnet bracket to protect it, and an electromagnet is placed on one side of the outside of the electromagnet bracket. It has a structure including a terminal box for driving the unit.

However, the excavator bucket described above has a problem in that the electromagnet unit can be easily damaged by external impact because the electromagnet bracket protrudes from the outer surface of the bucket. For example, if the electromagnet bracket hits a concrete wall when the boom is rotating, the electromagnet bracket may be crushed or completely separated, and the electromagnet unit inside may also be damaged and not work.

In addition, since the magnetic force of the electromagnet unit is guided to the bucket and magnetized, and the magnetized bucket has a structure in which iron waste is attached, there is a problem that the final output magnetic force is small. Since the magnetic force is small, heavy iron waste naturally cannot be lifted.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the attached drawings.

Figure 1 is a partially cut away perspective view of the magnetic force output type bucket 10 according to an embodiment of the present invention, and Figure 2 is an exploded perspective view of the magnetic force output type bucket shown in Figure 1. In addition, FIG. 3 is a view showing the magnetic force output type bucket of FIG. 1 viewed from a different angle, and FIG. 4 is a cross-sectional view of the magnetic force output type bucket.

As shown, the magnetic force output type bucket 10 according to this embodiment includes a bucket body 20, an electronic chuck 40, a blocking cover 30, and a cable shield 25.

The bucket body 20 includes side walls 21c that are parallel to each other, a curved bottom portion 21a fixed between the side walls 21c, a bracket fixing portion 21e located at the top of the bottom portion 21a, and a bracket. It has a pair of brackets 21g that are welded and fixed to the fixing portion 21e, and a tooth portion 21k provided at the tip of the bottom portion 21a.

The bracket (21g) is a part where the boom of the excavator (71 in FIG. 10) is connected and has a pin hole (21h). With the hole (not shown) at the end of the boom 71 positioned between the brackets 21g, the connecting pin 71a is inserted into the pin hole 21h to connect the bucket 10 to the boom 71. .

The bucket body 20 having the above configuration has a space portion 20a. The space portion 20a is, for example, a space where soil is contained when soil is pumped with an excavator.

In particular, a magnetic force output passage (21m) is provided at the bottom (21a). The magnetic force output passage 21m is a through hole formed by drilling the steel plate forming the bottom portion 21a, and allows the magnetic force of the electromagnetic chuck 40 to pass downward. Since the magnetic force of the electromagnetic chuck 40 is output downward, the scrap S can be attached to the lower part of the bucket body 20, as shown in FIG. 10.

The magnetic force output passage 21m accommodates the lower end of the electromagnetic chuck 40, as shown in FIG. 4. The lower end of the electromagnetic chuck 40 is welded to the bottom portion 21a in a state in which it faces the inner peripheral surface of the magnetic force output passage 21m. The welding portion (W) connecting the electromagnetic chuck (40) and the bottom portion (21a) runs along the circumference of the electromagnetic chuck (40) and fills the gap between the electromagnetic chuck (40) and the inner peripheral surface of the magnetic force output passage (21m). Completely sealed.

In addition, as shown enlarged in FIG. 4, the bottom of the tip portion 40a of the electromagnetic chuck 40 to be welded while inserted into the magnetic force output passage 21m is at least on the same plane as the bottom surface 21d of the bottom. It is located or rises upward by z1 (in the direction of the space portion 20a). The tip of the electromagnetic chuck 40 does not protrude below the bottom portion 21a.

The reason for designing it in this way is that when the bucket 10 is moved in the direction of arrow k, external demolition waste (e.g., crushed concrete, waste bricks, hardware, waste rebar, etc.) moving relative to the direction of arrow m is moved by the electromagnetic chuck ( 40) This was taken into consideration to avoid being caught. If the electronic chuck 40 protrudes from the lower part of the bottom surface 21d of the floor 21a, when the building is demolished, the electronic chuck 40 frequently collides with demolition waste, causing the internal circuit to be disconnected or the electronic chuck itself. Not only is it deformed, but the welded area (w) is split.

Additionally, as shown in FIG. 4, the rear end portion 40b of the electromagnetic chuck 40 protrudes by z2 below the bottom surface 21d of the bottom portion 21a. The reason it protrudes is because, while the electromagnetic chuck 40 has a constant thickness, the bottom portion 21a takes a curved shape.

In any case, the rear end portion 40b of the electromagnetic chuck 40 may protrude from the bottom portion 21a. This is because the rear end 40b does not get caught in cutting waste moving in the direction of arrow m. In this way, since the rear end portion 40b of the electromagnetic chuck may protrude beyond the bottom surface 21d of the bottom portion 21a, the area of the electromagnetic chuck 40 can be expanded as much as possible.

The shape of the magnetic force output passage (21m) corresponds to the shape of the electromagnetic chuck (40). Since the electromagnetic chuck 40 in FIG. 2 takes the shape of an octagon, naturally, the magnetic force output passage 21m is also an octagonal hole.

The blocking cover 30 is a steel plate fixed within the space 20a of the bucket body 20, and covers and protects the electromagnetic chuck 40. For example, it prevents the electronic chuck 40 from being damaged by external shock or being contaminated with contaminants.

The blocking cover 30 is manufactured by pressing a square steel plate and has a front end engaging portion 32, a front inclined portion 31, and a rear end engaging portion 33. The front end engaging portion 32 is welded to the upper surface of the front end of the bottom portion 21a, and the rear end engaging portion 33 is a portion welded to approximately the central portion of the bottom portion 21a. In addition, the front slope portion 31 is an inclined surface that guides soil in the direction of arrow g when the bucket 10 is moved in the direction indicated by arrow k in FIG. 4 .

In addition, a shield passage groove (33a) is formed on one side of the rear end coupling portion (33). The shield passage groove 33a is a groove through which the cable shield 25 passes.

The edge portion of the blocking cover 30 having the above configuration is welded to the bottom portion 21a, the side wall portion 21c, and the cable shield 25, and seals the space below it. For example, sand or sand, etc., cannot penetrate into the lower part of the blocking cover (30).

The electronic chuck 40 has an electronic chuck housing 43, a core and coil (not shown) installed inside the electronic chuck housing, and a power cable 41 that supplies power to the coil. When electricity is supplied through a power line, the coil is magnetized and outputs magnetic force to the outside. Since this electronic chuck 40 is general, its description will be omitted.

The power cable 41 of the electronic chuck 40 extends outside the bucket 10 through the cable shield 25 and the cable hole 21b and is then connected to the battery of the excavator. Power from the battery is applied to the electronic chuck through the power cable (41).

The cable shield 25 is made by bending a strip-shaped steel plate in the width direction and provides an extension passage 25a. The extension passage 25a is a space that accommodates and protects the power cable 41. The power cable 41 is protected while being accommodated in the extension passage 25a. The cable hole 21b is a through hole drilled in the bottom 21a.

Figure 5 is a diagram for explaining the configuration and mounting structure of the cover supporter 51 applicable to the magnetic force output type bucket 10 according to an embodiment of the present invention.

As shown, a cover supporter 51 may be further installed between the front slope portion 31 and the bottom portion 21a. The cover supporter 51 supports the front inclined portion 31 and prevents the front inclined portion 31 from collapsing due to an impact applied from the outside.

The cover supporter 51 is composed of a case 51a and a honeycomb structure 51c. The case 51a is a frame that accommodates the honeycomb structure 51c, and is welded to the front inclined portion 31 and the bottom portion 21a. The honeycomb structure 51c is a structure having a honeycomb structure and provides support while accommodated in the case 51a.

Figures 6 and 7 are cutaway perspective views showing a modified example of the magnetic force output type bucket 10 according to an embodiment of the present invention.

A circular electromagnetic chuck 40 is applied to the bucket 10 shown in FIG. 6, and a square electromagnetic chuck 40 is applied to the bucket 10 shown in FIG. 7. Each electronic chuck only has a different shape, but its operation and role are all the same. That is, magnetic force is output to the lower part of the bucket body 20 by power applied from the outside.

Figure 8 is a diagram showing the operation lamp 57 and the lamp controller 55 applied to the magnetic force output type bucket 10 according to an embodiment of the present invention.

Referring to the drawing, it can be seen that a lamp controller 55 and an operation lamp 57 are further installed on the upper part of the bracket fixing part 21e.

The lamp controller 55 is connected to the power cable 41 through a signal transmission line 23. While power is supplied to the electronic chuck 40 through the power cable 41, an electric signal is simultaneously applied to the lamp controller 55. The lamp controller 55 operates the operating lamp 57 while power is supplied to the electronic chuck 40. The lamp controller 55 can be coupled to the bracket fixing part 21e by bolting.

Reference numeral 21p is an upper hole through which the signal transmission line 23 passes.

The operating lamp 57 operates by receiving electrical signals from the lamp controller 55. The operation lamp 57 may be a rotating warning light. The operator can easily check whether power is currently being supplied to the electronic chuck 40 through the operation lamp 57 even from a remote location.

Figure 9 is a partial cross-sectional view showing another modified example of the magnetic force output type bucket 10 according to an embodiment of the present invention.

The magnetic force output type bucket 10 shown in FIG. 9 has an electromagnetic chuck 40 and a battery 60 at the lower part of the blocking cover 30. The battery 60 is a rechargeable battery and is connected to the electronic chuck 40 through a power cable 42. Of course, the power from the battery 60 is applied to the electric chuck 40, so that the electric chuck 40 operates.

Additionally, a charging terminal portion 61 is located on the bottom of the battery 60. The charging terminal portion 61 is an outlet into which a charging plug (not shown) is inserted. A charging passage 21r is provided in the bottom portion 21a so that the plug can approach the charging terminal portion 61. The charging passage 21r is a passage that opens the charging terminal portion 61 downward, and is opened and closed by the door 22.

The door 22 is a plate-shaped member linked to one side of the charging passage 21r through a pivoting pin 22c, and rotates in the direction of arrow p to block the charging passage 21r. To keep the door 22 in a closed state, a bolt hole 22a is formed at the free end of the door 22, and a female screw hole 21s is formed inside the charging passage 21r. After rotating the door 22 in the direction of arrow p, the fixing bolt 27 is screwed to the female screw hole 21s through the bolt hole 22a to complete the assembly of the door 22.

The battery 60 is a rechargeable secondary battery and has a battery controller 65 and a wireless communication unit 65a. The wireless communication unit 65a is a communication module that is wirelessly connected to the operator. Additionally, the battery controller 65 controls the output of the battery. That is, the power supply to the electronic chuck 40 is controlled.

When the worker transmits an operation or stop signal of the electronic chuck 40 to the wireless communication unit 65a through his or her terminal, the wireless communication unit 65a sends the corresponding signal to the battery controller 65. ) transmits power or stops power supply.

In this way, when the battery 60 is integrated into the bucket body 20, the power cable 41 connecting the excavator body battery and the electronic chuck 40 can be omitted.

Figure 10 is a diagram showing an operation example of the magnetic force output type bucket 10 according to an embodiment of the present invention.

As shown, scrap S is attached to the lower part of the bucket body 20. Of course, the scrap (S) is adsorbed by the magnetic force of the electromagnet (40). As described above, the magnetic force of the electromagnet 40 acts directly downward in the vertical direction through the magnetic force output passage (21m), so the output of the electromagnetic force is that strong and a larger amount of scrap can be lifted.
