Description

Oyster pile separator}

The present invention relates to an oyster heap separation device, which, more specifically, relates to an oyster pile separation device capable of effectively separating agglomerated cultured oysters harvested from the sea for each individual oyster.

In general, with the development of aquaculture, many kinds of aquatic products can be cultured in large quantities. In particular, for adherent aquatic products such as oysters, sea urchins, and seaweed, many water lines are connected to maintain a certain distance in a thick and long line, and seeds are attached to each line, and then hang under the surface of the farm in clean coastal waters and set aside. After the period has elapsed and it has grown to the extent that it can be commercialized, it is salvaged and collected.

Among these aquatic products, the oyster harvesting operation is carried out by a crane lifting the raw rope from the harvesting ship to a certain height and then transporting a large amount of farmed oysters using a conveyor. , and then the oyster mass is washed with high-pressure water and transferred to a workshop on land. However, since the oyster masses that have undergone the salvage operation in the workshop are agglomerated, in order to perform the subsequent oyster separation, it is necessary to step on them individually or use a tool such as a hoe to separate the oysters into individual oysters.

Accordingly, in Patent Registration No. 10-1432921 disclosed in the prior art, a screen passed by a driving device, a washing pipe installed across the inside of the screen barrel to spray washing water, a motor fixed to the outside of the screen barrel, and a screen An oyster pile object separation device is proposed, which consists of a separator comprising a motor shaft installed across the inside of the barrel, one or more separating blades installed on the motor shaft, and a shaft supporting the end of the motor shaft. Due to the structural nature of being hit by the separation blade while riding, the production of good products is reduced due to the breakage of oysters. In particular, the separation blade rotation radius is formed to be smaller than the inner diameter of the screen barrel and installed in an eccentric position, so the separation efficiency of oyster piles by the separation blade This markedly degraded problem followed

In addition, another prior art, Patent Registration No. 10-1474105, relates to an oyster separator that separates lifted oyster bundles into individual pieces using the rotational force of an oyster washer and a plurality of blades. An oyster washer comprising a drum and one or more protruding blades are coupled to a fixed shaft having a predetermined length so as to be positioned in the inner space in the longitudinal direction of the rotating drum to wash the oyster bundles inside the oyster washer Although the technology that includes an oyster separation unit to separate has been previously registered, since the oyster pile is moved on a rotating drum and is struck and separated in stages by a plurality of blades, the size of the rotating drum is enlarged, It cannot be applied to a place where the installation space is limited, and due to the structural characteristics of the blade rotation being stopped due to overload when the input amount of the oyster pile increases, there is a cumbersome problem of always having to quantitatively control the input amount of the oyster pile.

Hereinafter, the present invention will be described in more detail according to specific embodiments of the accompanying drawings. The following drawings according to an exemplary embodiment of the present invention are examples for explaining the structure and effects in detail, and thereby the technical scope of the present invention is not narrowly limited or changed. Therefore, it will be natural for those skilled in the art that various modifications can be made within the scope of the technical spirit of the present invention based on these embodiments.

1 is a block diagram showing a preferred embodiment of the oyster pile separation device provided by the present invention as a whole, Figure 2 is a plan view of the oyster pile separation device according to an embodiment of the present invention, the present invention is a harvested lump It relates to an oyster pile separation device for effectively separating cultured oysters by individual oysters, and is characterized in that it consists of a main component including a fixed drum (10), a rotating core (20) and a separation chamber (30) as a whole.

First, the fixing drum 10 according to the present invention is formed to be supported by the body frame in a cylindrical shape installed in the longitudinal direction, and the upper part is opened to form an inlet 12 into which the oyster piles are put, and the lower part is formed in the circumferential direction. An outlet 14 is formed.

An inclined hopper (H) is installed at the lower portion of the outlet 14 to discharge the oysters discharged through the outlet 14 in either direction.

A plurality of inward projections 11 are provided on the inner circumferential surface of the fixing drum 10, and the inward projections 11 are formed in a slanted blade structure that protrudes sharply toward the end as shown in FIG. The oyster piles are separated by a combination with the outward-facing protrusions 21 that are spaced apart and will be described later.

The rotating core 20 according to the present invention is installed inside the fixed drum 10, rotated by a power source 22, is formed in a cone shape whose diameter is expanded toward the bottom, and has a plurality of outwardly directed protrusions 21 on the outer circumferential surface. is provided The rotating core 20 is connected to the longitudinal axis 22a of the power source 22 installed in the body frame to perform a rotational motion, and the kinetic energy generated at this time is used to separate the oyster pile into the fixed drum 10. act as a driving force

The outward protrusion 21 is formed in a beveled blade structure that protrudes sharply toward the end like the inward protrusion of the fixing drum 10, and is spaced apart from the outer circumferential surface of the rotating core 20 at a plurality of places and is formed with the inward protrusion 11 The combination separates the pile of oysters.

That is, when the rotating core 20 rotates while the lumped oyster pile 1 is put into the fixing drum 10, the oyster pile 1 close to the inner surface of the fixing drum 10 is fixed. As the rotating core 20 rotates while being hung on the inward protrusion 11 in the state, a tensile force is applied to the oyster pile by the outward protrusion 21 to separate the oyster pile and the rotating core 20 ), the action of separately separating the lumped oysters while rubbing or hitting the outward projections 21 and the inward projections 11 is performed at the same time.

The separation chamber 30 according to the present invention is characterized in that it guides the movement of the oyster pile 1 between the fixed drum 10 and the rotating core 20, and is formed such that the space decreases toward the bottom. As described above, the fixed drum 10 is formed in a straight cylinder, and as the rotating core 20 is formed in a conical shape, the space between the inner diameter of the fixed drum 10 and the outer diameter of the rotating core 20 decreases toward the bottom. A seal 30 is formed.

Since the space of the separation chamber 30 is reduced as it goes down, if the oyster mass is not separated, it cannot go down, so the oyster mass is completely separated.

In addition, the oyster pile 1 input through the inlet 12 of the fixed drum 10 is separated into the separation chamber 30 by its own load and downward pressing action by the structure of the screw blades 16 and 26 to be described below. The separation action is made by the inward and outward projections 11 and 21 while moving downward.

Meanwhile, a plurality of screw blades 16 and 26 installed at an inclination angle on the inner circumferential surface of the fixed drum 10 and the outer circumferential surface of the rotating core 20 to forcibly transport the oyster pile 1 downward may be provided. The figure shows a state in which three screw blades 16 are applied to the inner circumferential surface of the fixed drum 10 , and also a state in which four screw blades 26 are disposed on the outer circumferential surface of the rotating core 20 .

And the inclination direction of the screw blades 16 and 26 should be designed according to the rotation direction of the rotating core 20 . That is, when the rotating core 20 rotates counterclockwise as shown in FIG. 2 , the oyster pile 1 collides with the screw blade 26 formed on the rotating core and the screw blade formed on the inner surface of the fixed drum 10 ( 16), the oyster pile (1) collided with the narrow outlet (14) direction is applied to the force is pushed down so that it can be formed inclined so that it can be separated.

Accordingly, as shown in the cross-sectional view showing the operating state of the oyster pile separation device shown in FIGS. 3 to 4 , the oyster pile 1 introduced through the inlet 12 of the fixing drum 10 has a narrow entrance due to its own weight. The branch is moved in the direction of the outlet 14, and as the rotating core 20 rotates, the screw blade 26 formed on the rotating core attracts and rotates the oyster pile. At this time, as the screw blade 16 on the inner surface of the fixing drum 10 is inclined so that the oyster piles are downward in the direction of the exit, a force is applied to force the oyster piles to move downward in the form of squeezing the oyster piles, thereby separating the oyster piles. This is made, and further, the oyster pile 1 is smoothly separated by the blow by the above-described inward projection 11 and outward projection 21 .

In this way, the finally separated oyster individual comes out through the gap of the outlet 14 and is guided to the inclined hopper (H) disposed below to be discharged to either side.

On the other hand, the piles that are not discharged between the gaps are continuously separated by the blow separation action of the inward and outward projections 11 and 21 and the downward pressing force by the screw blades 16 and 26, so that the piles are completely separated. is possible

An arcuate cap 40 for dispersing the oyster piles 1 fed into the inlet 12 of the fixed drum 10 in all directions may be formed on the upper portion of the rotating core 20 . At this time, the arcuate cap 40 is preferably manufactured to have a round shape by applying a synthetic resin or high-compression rigid foam material.

This minimizes the transport failure of the oyster pile, which is put together with the rope, on the top of the rotating core 20, while the oyster pile 1 rides the conveyor and falls freely into the fixed drum 10. This is to obtain the effect of preventing the oyster shell from being damaged by absorption.

5 is a cross-sectional view showing the configuration of a rotating core in the oyster pile separation device of the present invention, wherein the rotating core 20 is connected to the longitudinal axis 22a of the power source 22, and first and second The inner core 27 provided with support portions 27a and 27b, and the first and second upper and lower portions to be supported by the first and second support portions 27a and 27b in a state covered with the inner core 27; Two mounting portions 28a and 28b are formed, and an outer core 28 having an outward protrusion 21 on an outer circumferential surface thereof, and a space portion 29 formed between the inner and outer cores 27 and 28. . In the drawing, an example in which the first supporting part 27a and the first mounting part 28a are screwed by a bolt and a nut hole, and the second supporting part 27b and the second mounting part 28b are bound by a key and a keyway. is showing

As such, as the outer core 28 is provided to be replaceable on the inner core 27, damage to the outer peripheral surface of the outward protrusion 21 and the rotating core 20 is reduced in such a way that the outer core 28 is locally replaced. Also, according to the size of the oyster pile (1) and the size of the oyster individual (individual) size, the outer core 28 with a different size and outward projection 21 type is replaced and applied to provide a diverse oyster pile (1) separation environment This can increase versatility.

In addition, the space portion 29 formed between the inner and outer cores 27 and 28 provides a space in which the outer core 28 can elastically deform in the inward direction while the oyster pile 1 is separated. When the separation load applied to the pile 1 is momentarily increased, the outer core 28 is elastically bent inward to absorb the impact, thereby preventing the oyster shell from breaking due to the high load.

6 shows the separation chamber outlet size adjustment structure, the diameter of the lower end of the rotating core 20 is formed to be smaller than the inner diameter of the lower end of the fixed drum 10, and the fixed drum 10 or the rotating core 20 has a height is adjustable. As an example, it is configured to adjust the position of the rotating core 20 by adjusting the height of the fixed drum 10 in the upper and lower directions on the main frame, or by adjusting the height of the vertical shaft 22a of the power source 22 .

When the lower end of the rotating core 20 is positioned equal to or higher than the lower end of the fixed drum 10 as shown in FIG. , When the lower end of the rotating core 20 is positioned lower than the lower end of the fixed drum 10 as shown in FIG. 6 (b), the outlet 14 size is expanded (L2) by the conical structure of the rotating core 20. A relatively large pile of oysters is separated.

As such, since the size of the outlet 14 of the fixed drum 10 or the rotating core 20 varies according to the height adjustment configuration, a single oyster pile separation device is used at the offshore work site to effectively damage oysters of various sizes without damage. It has the advantage of being separable.

As described above, in the detailed description of the present invention, the most preferred embodiment of the present invention has been described, but various modifications may be made within the scope not departing from the technical scope of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but the protection scope should be recognized from the techniques of the claims to be described later and equivalent technical means from these techniques.
