Description

Automatic towing device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic sampling device for interlocking a towing line, and more particularly, to an automatic sampling device for a towing line interlocking type in which an object can be picked up only by lowering a sampling device connected to a towing line .

The harvesting device, which is mainly used for lifting and lowering up and down and collecting objects such as soil, sand, minerals, grain or waste, from land or water and unloading it, depends on its main use, It is designed and used in various forms.

As a prior art for such a harvesting apparatus, Korean Patent Registration No. 10-0951235 (Published on Apr. 5, 2010) discloses a technique for a device for correcting a length deviation of a bucket holding wire. The prior art includes a pair of left and right bucket members 131a and 131b, a bucket base 133 having an upper end connected to the lower ends of the first hold fibers 121a and 121b, a second hold wire 122a And a plurality of link bars 132 connecting between one end of the bucket members 131a and 131b and the bucket base 133. [

At this time, the bucket member is lifted and lowered by winding and unwinding of the first hold wire connected to the upper surface of the bucket base, and the bucket member is lifted and lowered by the second hold wire, The lower end of the bucket member can be pinched or widened so that the fuel or raw material can be poured and transported to the unloading place.

This prior art is advantageous in that it is structurally simple in that it uses only the winding and unwinding of the wire without using a separate actuator such as a hydraulic device for mechanical operation of the bucket member.

However, the fact that a plurality of wires are used for raising and lowering the ascending and descending rivers and the bucket members of the pair of bucket members themselves, and that a plurality of power units must be provided for operating each of these plurality of wires separately, It is necessary to improve the structure of the system because it is inconvenient to use or place restrictions and maintenance difficulties.

It is an object of the present invention to provide a towing device interlocking type which can easily take out an object by only moving up and down a single towing line while implementing a harvesting device that is structurally simple and simple using a minimized number of parts and a power unit And an automatic sampling device.

The object is achieved by a grab bucket comprising first and second buckets which are mutually pivotally moved by a hinge part, opened and closed, and collecting an object; A rod portion extending from both ends of the first bucket and the second bucket so as to intersect with each other and having first and second rods connected to the ascending and descending tow lines; And a grip portion provided between the grab bucket and the rod portion so as to maintain the opening state of the grab bucket when the pull string is lowered, and when the lowered grab bucket is placed on the object, Wherein the automatic triggering device includes an actuation trigger operative to enable the towing device to interlock.

The actuating trigger includes: an actuating projection formed to protrude outward along the axial direction of the hinge portion at an edge of the second bucket; And a rotating annular body rotatably coupled to the first rod so that the engaging or disengaging of the operating protrusion rotates according to the opening or closing operation of the grab bucket.

Wherein the rotary ring body includes a rotary shaft portion that rotates relative to the first rod and a ring portion that is selectively engaged or disengaged with respect to the operation projection extending and rotating toward the rotation radius of the operation projection in the rotary shaft portion, And a weight portion extended from the rotary shaft portion so that the hook is rotated in a direction to release the operation projection.

The grab bucket may further include first and second weights on the outside of the first and second buckets, respectively, so that a smooth retraction operation can be induced in a state where the grab bucket is buried in the object after descending to the open state.

The grab bucket may further include tooth irregularities engaging with each other at the ends of the first and second buckets which are in agreement with each other when the rim is operated so that the object can be easily picked up.

Wherein the pair of operating protrusions are provided so as to be symmetrical at both side edges of the second bucket, and the rotating ring member is fixed to the pair of operating protrusions so that each of the pair of operating protrusions is engaged or disengaged simultaneously, A pair of rotatable pairs is coupled to one rod, and a connecting rod is further provided between a pair of the weight portions facing each other.

The grab bucket may further include guide protrusions symmetrically formed on both side edges of the first and second buckets and protruding outward along the axial direction of the hinge part.

The guide protrusion may include a permanent magnet for pulling the rotation ring body so that the rotation ring body can be easily released from the operation projection.

The tow line interlocking type automatic collecting apparatus may further include a collection frame for converting the grab bucket descending to the crushed state into an open state, facilitating the unloading operation of the collected object, and accommodating the object.

Wherein the collection frame includes a top entry rail positioned below the grab bucket descending in a crumpled state and interposed between the guide projections of the first and second buckets; A sliding rail which slopes downward to the left and right of the upper entry rail and guides the guide protrusion to the left and right; And a collection box that supports the lower end of the sliding rail and accommodates the object to be dropped from the grab bucket which is opened and closed according to the left and right guide of the guide protrusion.

According to the present invention, when the pull string is lowered, the open state of the grip bucket is maintained, and when the grip bucket in the open state is placed on the object and tension is relieved on the pull string, Since the grab buckets operated by the weight are operated in cooperation with each other, the object can be easily collected only by lowering the tow line and raising the tow line.

In addition, since the collecting device can be realized in a simple and simple structure with the minimized number of components, and the collecting operation can be performed at an automated level using only one power device for simply raising and lowering the tow line, The device can be widely used for unloading or harvesting work in various fields without restrictions on usage or location, and can be mass-produced and maintained at low cost.

The second rod 120b is disposed above the first bucket 110a in such a manner that a pair of the first and

second rods

120a and 120b are arranged at both side ends of the second bucket 110b so that the hinge portions 112 are positioned below the first rods 120a As shown in Fig. The first rod 120a is connected to a winch (winch) 12 at its end, and is wound or unwound, and the pulling string 10 is fastened.

The first and

second rods

120a and 120b having the

rods

120a and 120b arranged in this manner are disposed in the first and

second buckets

120a and 120b with respect to the hinge portion 112 without interfering with each other like a bag of scissors (110a, 110b).

[

Between the grab bucket 110 and the rod 120 is specifically a gap between the second bucket 110b and the first rod 120a (see FIG. 1, etc.) adjacent to each other in a state in which the grab bucket 110 is opened, And may be between the first bucket 110a and the second rod 120b.

At this time, if the second bucket 110b and the first rod 120a (or the first bucket 110a and the second rod 120b) are fixed to each other, the grab bucket 110 can maintain the open state, The grip buckets 110 can freely open and close the grippers.

1 and 2, the operation trigger 130 according to the embodiment of the present invention includes the operation protrusion 132 and the rotation ring body 134 and the like, And the like.

The operation protrusion 132 is a component that is selectively engaged or disengaged with respect to the rotating ring member 134 to be described later while rotating together with the second bucket 110b with the hinge portion 112 as an axis, And is protruded outward from the edge of the bucket 110b in parallel with the axial direction of the hinge portion 112. [

The rotating ring member 134 is rotatably supported by the first rod 120a so as to be engaged or released with respect to the above-described operation protrusion 132 which rotates in accordance with the opening or closing operation of the grip bucket 110, Which is an annular component rotatably coupled to the housing.

The rotating ring member 134 is formed in a plate shape and includes a rotating shaft portion 134a, a ring portion 134b, a weight portion 134c, and the like, and may further include a connecting rod 134d.

The rotary shaft portion 134a is a component that is located at the center of the rotary ring member 134 and is axially coupled to the first rod 120a so as to rotate relative to the first rod 120a.

The ring portion 134b is annularly shaped toward the operation protrusion 132 from the rotation axis portion 134a so as to be selectively locked or unlocked with respect to the operation protrusion 132 rotating with respect to the hinge portion 112 Is an elongated component.

The weight portion 134c is a component that forcibly rotates the loop portion 134b in the direction to unlock the operation protrusion 132 and is formed to extend in the direction opposite to the loop portion 134b in the rotation axis portion 134a Lt; / RTI >

Due to the difference in the self weight due to the difference in shape between the weight portion 134c and the ring portion 134b, the rotation of the ring portion 134b about the rotation axis portion 134a causes the operation protrusion 132 to be engaged So that it can be induced naturally.

As described above, the operation trigger 130 composed of the operating projection 132 and the rotating annular body 134 is disposed between the second bucket 110b and the first rod 120a, as shown in FIGS. 1 and 2, (Two in total) symmetrical in forward and backward directions, and may be provided on only one side between the second bucket 110b and the first rod 120a.

The operation trigger 130 may be provided on either side between the first bucket 110a and the second load 120b or between the first bucket 110a and the second load 120b The first and

second buckets

110a and 120b may be provided symmetrically with respect to the first bucket 110a and the second bucket 110b and between the first bucket 110a and the second rod 120b and between the second bucket 110b and the first rod 120a (Four in total).

1 and 2, when the operation trigger 130 is provided as a pair between the second bucket 110b and the first rod 120a symmetrically with respect to the forward and backward directions, And the pair of buckets 110b are symmetrically formed at both side edges thereof.

The rotating ring member 134 is also rotatably coupled to the first rod 120a at the corresponding position so as to simultaneously engage or disengage the pair of operating protrusions 132 .

A connecting member 134d which is a heavy member is further provided between the pair of weight portions 134c facing each other so that the rotating ring member 134 can rotate more smoothly in the direction of releasing the operation protrusion 132 .

As shown in FIG. 4C, the connecting rod 134d for guiding the rotation of the rotary ring body 134 is supported by the operator during the unloading operation of the object G using the collection frame 140, And the operation protrusion 132 can be more smoothly fixed (pulled upward).

Meanwhile, as shown in FIGS. 1 and 4, the automatic pulling-towel type automatic collecting apparatus 100 according to the embodiment of the present invention includes a grab bucket 110 which descends into a tumbled state after collecting the object G And a collection frame 140 for facilitating the unloading operation of the object G and accommodating the object G while converting it into the open state.

This collection frame 140 may be configured to include a top entry rail 142, a sliding rail 144, a collection box 146, and the like.

At this time, the upper entry rail 142 is positioned below the grab bucket 110 descending in the crushed state, and the rod-shaped upper guide rail 142 is interposed between the

guide projections

118a and 118b of the first and

second buckets

110a and 110b Lt; / RTI >

The sliding rail 144 is a rod-shaped component that guides the

guide projections

118a and 118b of the descending grab bucket 110 to the left and right so that the first and

second buckets

110a and 110b are opened to each other, And may be integrally formed with the upper entry rail 142 so as to be inclined downward to the left and right of the upper entry rail 142, respectively.

The collection box 146 is provided with a bowl-shaped configuration for supporting the lower end of the sliding rail 144 and accommodating the object G falling from the grab bucket 110 which is opened and operated according to the right and left guides of the

guide protrusions

118a and 118b As a result, the grip bucket 110 can be manufactured to have a size sufficient to cover the open state of the grip bucket 110.

Hereinafter, a process of simply picking up the automatic sampling device 100 according to an embodiment of the present invention and then ascending and descending to easily collect the object G of water W will be described with reference to FIGS. 3A to 3D, .

3A, the operator loosens the pull string 10 to collect an object G such as a manganese nodule distributed on the floor of the water W, And the grab bucket 110 (automatic sampling device 100) is lowered to the water W. [

At this time, the tension T acting on each pull string 10 is approximately equal to the load of the first rod 120a and the first bucket 110a itself and the load of the second rod 120b and the second bucket 110b itself Respectively.

The loads of the second rod 120b and the second bucket 110b which balance the forces with the tension T applied to the left pull string 10 are eventually caught by the actuating projection 132 and the right pull string 10, The loads of the first rod 120a and the first bucket 110a which balance the force with the tension T applied to the rotating ring member 134 are finally caught by the ring portion 134b of the rotating ring member 134. [

As a result, the forces acting in opposite directions and the tension T held by the left and right pulling rods 10 are in equilibrium with each other in the state where the operation protrusions 132 and the hooks 134b are engaged and fixed , The grappling bucket 110 of the automatic sampling device 100 can be lowered to the water W while maintaining the opening state.

Next, the operator loosens the pull string 10 continuously until it reaches the bottom of the water (W) with the object G, as shown in Fig. 3B.

At this time, when the grip buckets 110 that have been opened and fixed reach the bottom of the water W having the object G, as the tension T acting on the pull string 10 disappears, (134b) in the direction opposite to each other, and the forces of equilibrium between the tension (T) and the force are also extinguished.

This causes the first and

second buckets

110a and 110b to be pivoted about the hinge portion 112 only by its own weight (①), and the operation protrusion 132 is also engaged with the second bucket 110b And is disengaged from the annular portion 134b of the rotary ring member 134 while rotating around the support portion 112. [ On the other hand, as the rotation of the rotating ring member 134, which freely rotates relative to the rotation axis portion 134a, is induced by the weight portion 134c and the linkage 134d, the operation protrusion 132 is more smoothly released (②)

Next, the operator pulls the pull string 10 so that an object G such as a manganese nodule distributed on the floor of the water W can be collected into the grab bucket 110, as shown in Fig. 3C, Thereby accelerating the crushing operation of the crankshaft 110.

At this time, the tension T 'acting on the right pull string 10 is approximately equal to the load of the first rod 120a and the first bucket 110a itself and the load G and the first bucket 110a are combined and expressed.

The tensile force T 'acting on the left pull string 10 is also determined by the load of the second rod 120b and the second bucket 110b itself and the load of the object G along with the rupture of the second bucket 110b And the resistance between the second buckets 110b are combined and expressed.

By pulling the pull string 10 simply by accelerating the gripping operation of the

grip buckets

110a and 110b, it is possible to quickly and easily collect the object G.

Finally, the operator pulls the pull string 10 continuously to unload the object G, which is obtained by the crushing operation of the

grip buckets

110a and 110b, as shown in FIG. 3D, , 110b (automatic sampling device 100) on the water surface.

At this time, the tension T acting on the pulling line becomes equal to the load of the automatic sampling device 100 of the present invention and the collected object G itself and the hinge portion 112, The first and

second buckets

110a and 110b can be raised in a state where they are firmly joined to each other and the loss of the object G collected by the first and second weight scales 114a and 114b can be further prevented.

The process of unloading the collected object G while converting the grab bucket 110 into the open state using the automatic collecting apparatus 100 and the collection frame 140 according to the embodiment of the present invention will be described with reference to FIGS. 4c will be described step by step.

First, in order to convert the grab bucket 110 into the open state and allow the collected object G to be accommodated in the collection box 146, the operator loosens the pull string 10 as shown in FIG. 4A The grab bucket 110 in the state (automatic sampling device 100) is lowered to be placed on the collection frame 140 located at the lower side.

4B, the worker moves the lower portion of the descending grab bucket 110 (or 110b) so that the

guide projections

118a and 118b of the first and

second buckets

110a and 110b and the sliding rail 144 can contact each other, ) Or adjusts the position of the collection frame (140) and loosens the towline (10) continuously.

At this time, when the grip buckets 110 in the closed state are continuously lowered while the

guide projections

118a, 118b of the first and

second buckets

110a, 110b and the sliding rail 144 are in contact with each other, The guide protrusions 118a of the bucket 110a and the guide protrusions 118b of the second bucket 110b move in the left and right directions in accordance with the guiding direction of the sliding rails 144, respectively.

As a result, the first and

second buckets

110a and 110b are widened to the left and right with respect to the hinge portion 112 in a combined state, and drop the object G collected inside the grab bucket 110.

Lastly, the operator must hold the grips 146 until the first and second buckets < RTI ID = 0.0 > 110a, < / RTI & The bucket 110 is continuously lowered.

The operation protrusion 132 formed on the second bucket 110b in the process of continuously lowering the grap bucket 110 as described above is rotated about the hinge portion 112 and is rotated around the hinge portion 112, And is naturally guided into the annular portion 134b of the annular groove 134.

At this time, the rotating ring member 134 relatively rotates relative to the first rod 120a with respect to the rotating shaft portion 134a and guides the operating projection 132 toward the ring portion 134b.

The operation protrusion 132 guided and rotated toward the inside of the annular portion 134b is firmly seated in the inner groove of the annular portion 134b together with the rotation of the rotary annular member 134, The first and

second buckets

110a and 110b can not be disengaged even if the pulling string 10 is pulled again for a continuous collection operation.

As a result, the operation protrusion 132 and the claw portion 134b are formed so that the opening state of the grip bucket 110 can be maintained firmly as the forces are balanced with the pull string 10 as shown in Fig. 3A do.
