≪ Embodiment 1 >

FIG. 1 is a plan view showing a construction of a load-field expelling bucket apparatus having an automatic discharge mechanism of a magnetic force-driven raw material according to a first embodiment of the present invention, FIG. 2 is a view showing a raw material discharging process according to a first embodiment of the present invention 3 is a plan view showing another configuration of the magnetic force driving member and the magnetic force generating member according to the first embodiment of the present invention.

A load-carrying bucket device with a self-powered feedstock automatic discharge structure has a basic structure in which a plurality of buckets (B) are installed on a chain conveyor (C) at regular intervals and repeatedly rotated in a circulating orbit, , Minerals and other raw materials to a desired place.

In the process of transferring and discharging the raw material by the bucket B, the raw material contained in the bucket B is attached to the inner bottom or the side wall, so that the raw material can be completely discharged without remaining.

The present invention can be applied to a bucket (B) installed on a chain conveyor (C) having a circulation orbit; A raw material discharging member 10 installed in the bucket B and assembled to be movable in a raw material discharging direction; A movable member 20 connected to an outer surface of the raw material discharging member 10 and installed outside the bucket B so as to be reciprocable in a raw material discharging direction; A magnetic force driving member (30) provided outside the bucket (B) so as to move the movable member (20) in a material discharge direction and having a magnetic pole of N pole or S pole at an outer end thereof; And a magnetic force generating member (40) arranged along the discharge section of the chain conveyor (C) and generating a pulling force or a repulsive force corresponding to the magnetic pole of the magnetic force driving member (30).

That is, the magnetic force generating member 40 made of a permanent magnet or an electromagnet is provided in the discharge section of the chain conveyor C to generate an N pole or an S pole, and an alternating force or repulsive force, The magnetic force driving member 30 reciprocates the raw material discharge plate 11 mounted in the bucket B in the raw material discharge direction so that the raw material in the bucket B is completely discharged will be.

Specifically, the raw material discharging member 10 is installed inside the bucket B and is assembled so as to be movable in a raw material discharging direction.

The raw material discharging member 10 may be composed of the raw material discharging plate 11 having an outer shape corresponding to the bottom surface of the bucket B and closely attached to the bottom surface of the bucket B.

The raw material discharging plate 11 is made of a metal (stainless steel plate) or a reinforced synthetic resin (nylon) having a low coefficient of friction so that coal or minerals do not adhere to the surface and are subjected to post- .

The movable member 20 may be a circular or plate-shaped member for pushing the raw material discharging plate 11 in the direction of discharging the raw material. The movable member 20 may include a movable rod (not shown) integrally connected to the bottom surface of the raw material discharging plate 11 21).

The movable rod 21 is installed to penetrate the bottom surface of the bucket B and is assembled so as to be reciprocally movable in the direction of discharging the raw material. In the assembled part, a bushing, a slide bearing or the like And is configured so as to be smoothly reciprocally moved.

A driven cam 22 is formed at the other end of the movable rod 21. The driven cam 22 has a curved surface with a central portion protruding and is inclined to the edge.

Therefore, the driven cam 22 is configured to contact the cam surface of the drive cam 32 described later and reciprocate in the material discharge direction.

The elastic rod S1 is assembled to the outer side of the movable rod 21 so that the movable rod 21 is elastically deformed outwardly by the action of the driven cam 22 and the drive cam 32, And then returns to its original position after being raised in the direction of discharging the raw material.

When the magnetic force generating member 40 is made of a permanent magnet or an electromagnet, the magnetic force driving member 30 reciprocates by the attractive force and the repulsive force generated corresponding to the N pole or the S pole.

The magnetic force driving member 30 is installed on the bottom surface of the bucket B so as to be slidable in a direction orthogonal to the movable rod 21. [

The magnetic force driving member 30 is supported on a pair of support frames 34 provided on the bottom surface of the bucket B so as to be slidable in a direction orthogonal to the movable rod 21 And a reciprocating rod 31 installed therein.

A movable magnet (33) having one of an N pole and an S pole at an outer end of the reciprocating rod (31) is included.

For example, the movable magnet 33 is assembled so as to face the fixed magnet 41 described later at the outer end of the reciprocating rod 31 and repelled by repulsive force by the same magnetic poles so that the movable magnet 33 is rotated by the reciprocating rod 31).

At this time, the reciprocating rod 31 is further provided with the second elastic body S2 so as to return the reciprocating rod 31 to its original position.

For example, the second elastic body S2 functions to elastically move the reciprocating rod 31 in the opposite direction to the attraction force or the repulsive force generated between the movable magnet 33 and the stationary magnet 41.

In this case, the second elastic body S2 and the elastic body S1 may be coil springs, and any form that can move the movable rod 21 and the reciprocating rod 31 in place other than the coil spring is applicable to the present invention It is possible.

Further, a stopper 31a is provided on one side of the reciprocating rod 31 so as to be in contact with the outer side of the support frame 34.

The stopper 31a restricts the movement width of the reciprocating rod 31 to the left and right so as to maintain a noncontact state in which the repulsive force and the attractive force do not strike each other when the repulsive force and the attractive force repeatedly act between the movable magnet 33 and the stationary magnet 41 So that the reciprocating rod 31 can be stably moved left and right.

It is preferable that a buffering member (not shown) is interposed between the stopper 31a and the support frame 34 so as to mitigate the impact when the stopper 31a is repeatedly brought into contact with the outer surface of the support frame 34 Do.

3, a boss 34a formed at an end of the support frame 34 is provided with a slip member such as a bushing or a slide bearing for sliding friction, (31b) may be further provided.

The driving cam 32 is provided so as to be in contact with the cam surface of the driven cam 22,

The driving cam 32 reciprocates left and right and the driven cam 22 is moved upward and downward by the difference in height between the top dead center (the largest diameter of the outer diameter) and the bottom dead center (the smallest outer diameter) .

As the movable rod 21 and the raw material discharge 11 are moved downward in the raw material discharge direction during the passage of the bucket B through the raw material discharge section, the raw material in the bucket B is forcibly pushed out, .

The magnetic force generating member 40 may include a plurality of stationary magnets 41 arranged at positions corresponding to the movable magnet 33 in the discharge section of the chain conveyor C. [

That is, the stationary magnet 41 is formed at a position facing the movable magnet 33 and is formed in a shape (approximately sector shape) corresponding to the rotational curvature in which the bucket B is circulated, and the stationary magnet 41 ) May be composed of a permanent magnet or an electromagnet.

For example, in the case of a permanent magnet, the unit fixed magnets of the N pole and the S pole are alternately arranged in a fan shape, and the movable magnet 33 has the polarity of either the N pole or the S pole, Is moved close to the stationary magnet 41, so that attractive force and repulsive force are repeatedly generated between the stationary magnet 41 and the movable magnet 33.

As the drive cam 32 contacts the driven cam 22 at this time, the movable rod 21 and the raw material feeder 11 are moved in the left and right directions, While the bucket B passes through the discharge section, the upward and downward operations are continuously performed in the direction of discharging the raw material.

For example, as shown in FIG. 2, when the bucket B moves vertically while containing the raw material and then enters the initial discharge period, the bucket B is in a vertical state, gradually changed to a side posture, So that the raw material discharge 11 can flow.

That is, the buckets (B) that have entered the initial stage of the raw material discharge gradually move back and forth in the raw material discharge direction several times during the raw material discharge end section through the raw material discharge intermediate section.

Of course, in the initial stage of discharging the raw material, since the raw material in the bucket B remains, the reciprocating movement of the raw material discharging plate 11 may be small, but the bucket B may be reversed Most of the internal raw materials are discharged.

Therefore, the reciprocating movement of the raw material discharge plate 11 becomes more active due to the attractive force and the repulsive force generated between the movable magnet 33 and the stationary magnet 41, so that the raw material remaining on the bottom side of the bucket B, And can be completely discharged by reciprocating movement of the discharge tube 11.

Next, the bucket B which has passed through the raw material discharge end section is turned upside down, and the movable magnet 33 is out of the installation section of the stationary magnet 41.

The material discharge plate 11 is brought into contact with the bottom surface of the bucket B by being displaced by the elastic body S1 and at the same time the reciprocating rod 31 is also positioned by the second elastic body S2, It is possible to transfer a quantity of raw materials while cycling to a stacked loading station.

As shown in Fig. 3, in the first embodiment of the present invention, the movable magnet 33 is provided with a pair of magnets having the same magnetic poles at both ends of the reciprocating rod 31, (41) are arranged on both sides of the bucket (B) (B) in a pair.

Further, the drive cams 32 are also formed as a pair so as to face each other with the driven cam 22 as a center.

The magnetic pole of the fixed magnet 41 is formed such that the same magnetic pole or opposite magnetic pole is staggered with respect to the magnetic pole of the movable magnet 33.

For example, when the stationary magnet 41 on the right side in FIG. 3 is the S-pole, the left stationary magnet 41 facing the stationary magnet 41 is configured to be N-pole.

Accordingly, the movable magnet 33 is reciprocally operated without the second elastic body S2 by the attractive force and the repulsive force repeatedly generated between the N and S poles of the stationary magnet 41 .

In addition, in the first embodiment described above, if the distance between the S pole and the N pole of the fixed magnet 41 is made narrow, the reciprocating speed of the movable magnet 33 increases, It can be driven in a vibrating manner like a vibrator.

On the other hand, if the spacing between the S pole and the N pole of the fixed magnet 41 is wide, the number of reciprocating movements of the movable magnet 33 can be reduced.

At this time, if the S pole or the N pole interval of the stationary magnet 41 is increased, the movable magnet 33 is pulled by the attractive force or pushed by the repulsive force. Therefore, the material discharge plate 11 is moved toward the material discharge direction So that the state of being held or in close contact with the bottom plate can be temporarily maintained.

Thus, the arrangement of the S pole and the N pole of the stationary magnet 41 can be changed to vibrate the raw material discharging plate 11 in a vibrating manner, thereby causing the raw material discharging plate 11 to be temporarily shaken to cause an impact And can be variously configured so as to discharge the raw material adhered to the inner wall of the bucket B as if it is shaken at a time.

For example, although not shown in the drawing, since a large amount of raw material is stored in the bucket B during the initial stage of discharging the raw material, the interval between the S pole and the N pole of the stationary magnet 41 is widened, And the distance between the S pole and the N pole of the stationary magnet 41 gradually decreases from the point of time when the raw material is discharged.

According to such a configuration, when the raw material is discharged and the force due to the weight of the raw material is reduced in the raw material discharge 11, the raw material discharge 11 is operated in a vibrating manner, Of course, the raw material attached to the sidewall of the bucket B can be easily and completely discharged by the vibration of the raw material discharging plate 11.

≪ Embodiment 2 >

FIG. 4 is a side view illustrating a construction of a load-field expulsion bucket apparatus having a magnetic force-driven raw material automatic discharge structure according to a second embodiment of the present invention, and FIG. 5 is a side view showing a raw material discharging process according to a second embodiment of the present invention And FIG. 6 is a partial side view of the loading and unloading apparatus showing another configuration of the raw material discharging process according to the second embodiment of the present invention.

According to the second embodiment of the present invention, since the material discharging member 10 and the movable member 20 are constructed in the same manner as in the first embodiment, the same names and codes are applied to the second embodiment as it is.

That is, the raw material discharging member 10 is made of a raw material discharging plate 11 installed in close contact with the bottom surface of the bucket B.

The movable member 20 is composed of a movable rod 21 which is connected at one end to the bottom surface of the raw material discharging plate 11 and is assembled so as to be movable in a raw material discharging direction through a bottom surface of the bucket B.

However, in the second embodiment, there is a difference in that the movable link 21 includes the pivot link 23 at the other end.

One end of the pivotal link 23 is hinged to the other end of the movable rod 21, and the middle portion thereof is hinged to the bucket B.

And an elastic body (S1) for elastically extinguishing the movable rod (21).

The magnetic force driving member 30 is composed of a movable magnet 33 provided at an outer end of the rotation link 23 and having a magnetic pole of either an N pole or an S pole.

The magnetic force generating member 40 is disposed at a position corresponding to the movable magnet 33 in a discharging section of the chain conveyor C or a stationary magnet in which N poles and S poles are alternately arranged 41).

The stationary magnet 41 is disposed between the bucket B and the sprocket of the chain conveyor C and arranged in the circumferential direction in the discharge section in which the bucket B is pivoted.

According to another aspect of the present invention, the stationary magnet 41 is made of a permanent magnet and has the same magnetic pole as the magnetic pole (N pole) of the movable magnet 33 as shown in FIG. 5, N2 < N3 as the intensity of the magnetic force of the magnetic field generator 40 increases from the initial stage of discharging the raw material to the end of discharging the raw material.

That is, when the bucket B enters the raw material discharge section, the raw material discharging plate 11 is moved in the direction of discharging the raw material, so long as the magnetic force is not applied with a large magnetic force more than the pressing force by the self weight of the raw material, It is difficult to operate.

In other words, since the attitude of the bucket B is inclined in the discharge direction in the vertical direction in the initial stage of discharging the raw material, the magnitude of the magnet of the stationary magnet 41 is gradually increased from the middle of the raw material discharge to the end of the raw material discharge The raw material discharge plate is configured so as not to overdo it by the magnetic force as the raw material is discharged.

Therefore, since the magnetic force of the stationary magnet 41 is increased from the middle of discharging the raw material in the bucket B, the movable magnet 33 is pushed by the repulsive force.

At this time, the rotary link 23 rotates while rotating around the hinge point, and the rotary link 23 pushes the movable rod 21 and the raw material discharge 11 in the direction of discharging the raw material.

Since the raw material in the bucket B is completely discharged during the end of the raw material discharge, the raw material discharge 11 is returned to its original position by the elastic body S1 by the elastic body S1.

Further, as shown in FIG. 6, the stationary magnet 41 may be configured such that the N pole and the S pole are alternately repeated.

According to this configuration, when the movable magnet 33 provided at the end of the pivot link 23 passes through the N pole and the S pole of the fixed magnet 41, the attractive force and the repulsive force act on the pivot link 23 Reciprocating motion within the range.

As a result, the movable rod 21 connected to the pivotal link 23 and the inner end of the pivotal link 23 and the raw puddle plate 11 are repeatedly lifted and returned to their original positions during reciprocating movement in the raw material discharge direction, (B) The raw material of the inner bottom as well as the raw material attached to the inner wall can be completely discharged together.

For example, if the spacing between the S pole and the N pole of the stationary magnet 41 is made narrow, the reciprocating speed of the movable magnet 33 increases, so that the material discharge plate 11 can be driven in a vibrating manner like a vibrator have.

On the other hand, if the spacing between the S pole and the N pole of the fixed magnet 41 is wide, the number of reciprocating movements of the movable magnet 33 can be reduced.

At this time, if the S pole or the N pole interval of the stationary magnet 41 is increased, the movable magnet 33 is pulled by the attractive force or pushed by the repulsive force. Therefore, the material discharge plate 11 is moved toward the material discharge direction So that the state of being held or in close contact with the bottom plate can be temporarily maintained.

Thus, the arrangement of the S pole and the N pole of the stationary magnet 41 can be changed to vibrate the raw material discharging plate 11 in a vibrating manner, thereby causing the raw material discharging plate 11 to be temporarily shaken to cause an impact And can be variously configured so as to discharge the raw material adhered to the inner wall of the bucket B as if it is shaken at a time.

Although not shown in the drawings, since the raw material in the bucket B is stored in a large amount at the initial stage of discharging the raw material, the gap between the S pole and the N pole of the stationary magnet 41 is widened, And the distance between the S pole and the N pole of the stationary magnet 41 gradually decreases from the point of time when the raw material is discharged.

According to such a configuration, when the raw material is discharged and the force due to the weight of the raw material is reduced in the raw material discharge 11, the raw material discharge 11 is operated to vibrate like a vibrator, The raw material attached to the side wall of the bucket B as well as the raw material of the raw material discharging plate 11 can be easily completely discharged by the vibration of the raw material discharging plate 11. [

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
