Registered Patent No. 10-1761875 collects shellfish with a collection unit, transports them to the collection unit through a transfer unit, and then washes them.

Conventionally, collecting clams by hand requires many workers, resulting in high labor costs and poor productivity.

On the other hand, in the case of mechanical harvesters, labor costs can be reduced, but it is only a process of scooping out and sorting mud flats and shellfish, and the characteristics of the mud flats are not taken into consideration, so productivity is poor and equipment is severely damaged. To be specific, tidal flats have a high moisture content and high viscosity, so when collected, they are collected in the form of lumps, and since the clams are buried, a large amount of energy is required for collection, and the burden on the harvesting equipment is large, so it is easy to deform and the clams are in a lump form. Even though a large amount of high-pressure water is used to sort clams, it is very difficult to obtain clean clams with pearls removed.

In addition, during the process of collecting clams, they cannot be collected by the collector and a large amount is lost on the left and right sides of the collector, necessitating several repeated trips and operations.

Public Patent No. 10-2020-0049692 Public Patent No. 10-2017-0055633

The present invention is intended to solve the problems described above, and uses mechanical principles to collect a large amount of shellfish (clams) with only a small number of workers, and also reduces the collection of pearls other than shellfish through disturbance and dispersion of pearls and shellfish. The purpose is to provide a shellfish harvester and a shellfish collection method using the same that can improve productivity and reduce damage to equipment by mixing mudflats and improving the mudflats to cultivate (grow) large quantities of high-quality clams even after harvesting. .

Another purpose of the present invention is to efficiently collect large amounts of clams through a series of continuous processes of disturbance dispersion, alignment, collection, and transport.

In addition, clams dispersed in tidal flats and disturbances are guided to the collector without leaving the collection area, allowing rapid collection without duplicating travel through areas that have already passed.

The shellfish harvester according to the present invention includes a disturbance device that disturbs and disperses the mudflats and clams by spraying fluid into the clam harvesting area, digging up the mudflats, or digging up the mudflats while spraying fluid; A scraper for collecting clams dispersed through the fluid sprayer; It is characterized in that it includes a storage bin for storing clams collected by the scraper.

The present invention is characterized by comprising an aligner disposed between the disruptor and the scraper and collecting clams dispersed through the disruptor to the center.

The method according to claim 1, characterized in that it includes a feeder that transfers the clams collected by the scraper to the storage means at a predetermined amount.

According to the shellfish harvester and the shellfish harvesting method using the same according to the present invention, clams are harvested using automated equipment, which reduces labor costs compared to manual harvesting.

In addition, it has the effect of automating the work from collecting to supplying clams and supplying high-quality clams by collecting a large amount of clams without damage through optimal processes of distribution, alignment, collection, transportation, and storage.

In addition, by dispersing the mud flats and clams by spraying water under high pressure or digging up the mud flats with hooks and raising the clams in the mud flats to the upper part of the mud flats, this reduces the burden on the scraper and also reduces the clams remaining in the mud flats, thereby increasing the production of clams. It works.

In addition, according to the present invention, the quality of the mudflats is improved because the mudflats are turned over and mixed while collecting clams, and thus a greater amount of high-quality clams can be cultured (grown) after collection. In particular, disturbance, alignment, collection and dispersion By mixing the mudflats well in four stages, the mudflats can be created in an optimal condition for growing clams.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. The terms described below are defined in consideration of the functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, the definition should be made based on the contents throughout this specification.

As shown in Figure 1, the shellfish harvester 100 according to the present invention includes a disturbance device 10 that disturbs and disperses tidal flats (including natural tidal flats and fish farms) and clams; A sorter (20) that collects the clams dispersed through the disruptor (10), a scraper (30) that collects the clams sorted through the aligner (20), and a certain amount of clams collected by the scraper (30) are transported. Feeder (40), a storage means for storing clams transported by the feeder (40), including a storage bin (50), using the organic automation principles of disturbance and dispersion of the tidal flat - central alignment - collection - transport - storage to collect clams. It is used to collect and use an engine (or motor) as a driving source and is connected to traveling equipment (tractors running along tidal flats, ships floating on the water, etc.) that include wheels (or tracks). Among the above configurations, the aligner 20 and the feeder 40 are selected and used as needed, and the driving source for driving the configuration of the present invention is, for example, a hydraulic motor or a hydraulic pump.

1. Disruptor (10).

The disruptor (10) disturbs and disperses the tidal flats where the clams are located, allowing the clams buried in the tidal flats to come to the surface, and also removes the tidal flats from the clams, thereby relieving the burden on the aligner (20) and scraper (30), which are subsequent operations. The goal is to increase the harvest of clams.

The disruptor 10 can be a method that sprays water (seawater) as a fluid at high pressure (hydraulic pressure disturbance type) or a method that combines spraying water at high pressure with a hook that digs the mud flat (hydraulic pressure and hook disturbance type). .

The hydraulic pressure disturbance type is, for example, a water tank, a pump for pumping water from the water tank, a supply pipe 11 for supplying water pumped by the pump, and high pressure spraying of water supplied through the supply pipe 11 toward the mudflat. Includes a nozzle (12).

The nozzles 12 can be either a fixed type, in which multiple nozzles are installed at a certain distance from each other along the left and right width directions of the scraper, or a movable type, in which multiple nozzles are installed so that they can move back and forth left and right along the left and right width directions of the scraper. The latter, the mobile type, is more effective than the fixed type. It is useful in that manufacturing costs can be reduced and disturbance processes can be observed.

In addition, in the case of a movable nozzle, it is possible for one nozzle to move back and forth across the left and right width of the scraper 30, but it is more useful to have two or more nozzles move in that it can increase the sampling speed. .

The movable nozzle 12 is movably mounted on a guide rail 13 installed in the left and right width directions, and limit switches or sensors are applied to both left and right sides to control the left and right movement of the nozzle 12. The left and right movement of the nozzle 12 is possible through various driving means such as hydraulic motors and chain types.

As shown in Figure 4, the water pressure and hook disturbance equation (10-1) is configured to spray water with a plurality of hooks (14). For example, the plurality of hooks (14) are configured to spray water along the circumferential direction (see drawing). (shown as an example of three) are formed to have a phase difference along the axial direction and are coupled to, for example, a nozzle 14-1 that sprays water and both sides of the nozzle 14-1, forming pearls. It may be composed of a scooping hook plate (14-2).

In addition, the hook 14 has a structure whose cross-sectional area changes so that the pearls scooped up from the tidal flat can be quickly removed.

2. Aligner (20).

The aligner 20 consists of a rotation axis 21 and alignment beads 22 and 23 formed in opposite directions on both left and right sides of the circumference of the rotation axis 21, and is disposed at the rear of the disruptor 10 to control the disruptor ( Through 10), the clams that are disturbed and dispersed are guided to the scraper (30) without being lost to both the left and right.

The rotation shaft 21 is rotatably connected to the left and right rods of the frame 60 on both sides in the axial direction, respectively.

The alignment beads 22 and 23 are arranged at a certain distance based on the center of the rotation axis 21. That is, the central part of the circumference of the rotation axis 21 is a part without beads and includes the collection part 24. If the first and second aligned beads 21 and 22 are formed to the center without the collection part 24, a collision of clams, etc. may occur in the center, that is, the collection part 24 is a buffer section where clams can gather without damage. .

The aligner 20 of this configuration acts to move the alignment beads 22 and 23 in opposite directions when the rotation shaft 21 rotates, thereby aligning the clams on both the left and right sides among the clams distributed in the disruptor 10. They are collected in the central collection part 24, and therefore, there is no loss in the clams being collected at both left and right ends of the scraper 30.

The aligner 20 can rotate the rotation shaft 21 in both directions through the control of a hydraulic motor, and if necessary, rotates the rotation shaft 21 in the opposite direction to move tidal flats, etc. to the left and right sides of the shellfish collector 100. It is also possible to remove it in front of the scraper (30) by moving it to .

The aligner 20 is configured to be height-adjustable. For example, while forming long holes 62 in the vertical direction in the frame 60, height adjustment holes 63 are formed in multiple stages next to the long holes 62. , while inserting the rotating shaft 21 into the long hole 62 so as to be able to lift and lower, the fixing plate 25 of the peripheral part is inserted into the height adjustment hole 63 of any one of the multi-stage height adjustment holes 63 with a fastener 26 (bolt, etc.) ) to secure it.

By adjusting the height of the aligner (20), damage caused by the aligner (20) colliding with the road when driving on a road other than the collection site can be prevented, and the aligner (20) can be adjusted to an appropriate level for collecting clams. By installing it at a depth, you can align clams in the mud flat.

3. Scrapper (30).

The scraper 30 is composed of a rotating shaft 31 and a plurality of scraper blades 32 formed around the rotating shaft 31 at regular intervals from each other along the circumferential direction.

The rotation shaft 31 is rotatably connected to the left and right rods of the frame 60 on both sides in the axial direction, and rotates using a hydraulic motor as a driving source. Preferably, it rotates in both directions in the harvesting direction and in the opposite direction.

The scraper wings 32 are configured to have different lengths, and as shown in FIG. 5, the shorter first scraper wings 33 and the longer second scraper wings 34 alternate along the circumferential direction. It is formed to repeat, and therefore, the first scraper wing 33 first digs up the mudflat, and then the second scraper wing 34 digs up the mudflat, thereby relieving the burden on the first and second scraper wings 33 and 34. This can ultimately prevent damage to the first and second scraper wings (33,34).

From a manufacturing standpoint, it is preferable that the scraper blade 32 is formed on a cylindrical hub and is applied by fixing the hub to the rotating shaft 31 rather than being directly fixed to the rotating shaft 31.

In addition, when the scraper blade 32 rotates, a part of the scraper blade 32 may become caught in the tidal flat and may not rotate. In this case, the scraper blade 32 in the part where rotation is difficult may be stopped or rotated in the tidal flat even if the rotation speed is different. The scraper blade 32 is configured to be divided into a plurality of pieces along the axial direction of the rotation axis 31 so that the scraper blade 32 rotates normally in places where it is not subjected to interference.

As shown in Figure 6, a plurality of scraper blades (32-1, 32-2, 32-3, 32-4) (4 as an example) are mounted along the axial direction on the rotation shaft 31. , each scraper blade (32-1, 32-2, 32-3, 32-4) has other scraper blades (32-1, 32-2, 32-3, 32-4) adjacent to the rotation axis (31). It is mounted so that it can rotate freely without interference from other clams, and of course, it can rotate freely only for a certain section through an elastic member, etc. for the collection of clams, and the initial position (a plurality of scrapers 32 are arranged on the same line) It can be configured to return to position).

The first and second scraper wings (33, 34) are in the form of a plate with a curved cross-section, may include a hole through which seawater and tidal flats pass, and can be a single plate or a double structure of rubber and steel plates, and have a hook shape. It is also possible.

The disruptor 10, aligner 20, and scraper 30 described above share the rods on the left and right sides of the frame 60, that is, the guide rails 13 of the disruptor 10 are on both left and right sides of the frame 60. ) is fixed to the left and right rods, and both left and right sides of the aligner 20 and the scraper 30 are rotatably connected to the left and right rods of the frame 60.

The scraper 30 is also installed to be height adjustable to achieve the same purpose as the aligner 20, and its method is the same as the height adjustment configuration of the aligner 20.

4. Feeder (40).

The feeder 40 contains clams collected by the scraper 30 and is rotatably installed along the left and right width directions inside the feeder case 41, which is provided with a discharge part on one of the left and right sides. The feeding screw 42 rotates through the rotational force of the motor and transfers the clams to the discharge portion. One side is connected to the discharge portion of the feeder case 41, while the other side corresponds to the storage container 50 to store clams in the storage container 60. A feeding hose 43 that is preferably flexible and elastic for dropping, and a blocking plate 44 formed at the front end of the feeder case 41 to guide clams on the floor to the feeder case 41 and prevent clams from falling out. Includes.

The feeder case 41 has a structure in which the front part facing the scraper 30 is open and the remaining part is closed, the bottom part can be inclined downward toward the discharge part, and there is also a hole (straight type, circular shape, etc.) may be included.

The feeder case 41 is connected to the left and right rods of the frame 60.

In particular, the feeder case 41 is tiltably connected to the frame 60 so that the clams collected by the scraper 30 do not fall back into the tidal flat. For example, the end of the frame 60 is connected to the feeder case 41. It is rotatably connected through an axis pin (45) at a point spaced rearward from the front end, and therefore, when the feeder case (41) is slightly lifted, the feeder case (41) slopes downward toward the rear, preventing the clams in the front from falling out. They are collected inside the feeder case (41). At this time, even if the feeder case 41 is inclined, the blocking plate 44 is tilted and supported on the bottom of the tidal flat, so that the clams collected by the scraper 30 and the clams in the tidal flat are stored in the feeder case 41 without loss. .

A stopper may be configured to prevent the feeder case 41 from tilting beyond a certain angle. The stopper may be configured to include a key protruding from the end of the frame 60 and a jaw formed on the left and right sides of the feeder case 41 and supporting the key to restrain the tilting of the feeder case 41.

The feeder 40 may further include a washing water sprayer 46 for washing clams temporarily stored in the feeder case 41. The washing water sprayer 46 is piped along the left and right width directions to the washing water (sea water) tank, a pump for pumping water from the washing water tank, and the feeder case 41, and is connected to the pump to supply washing water, a supply pipe connected to the supply pipe. It is formed at regular intervals and includes a nozzle that sprays washing water.

Since the feeder case 41 is placed at the rear and closest to the traveling equipment 200, it is preferable that the boom 210 of the traveling equipment 200 is connected to it.

5. Reservoir (50).

The storage container 50 is, for example, mounted at the rear of the traveling equipment 200 and has a container structure with an open top so that clams transported through the feeding hose 43 can be contained therein.

In addition, the storage bin 50 preferably has a double structure so that the clams recovered inside can be supplied to the sorter 300, and is composed of a bottom, a back, and left and right side walls 51a, and is open toward the top and front. It includes a reservoir main body 51, a front part, and left and right side walls 52a, and the bottom part is hinged to the reservoir main body 51 and consists of a cover 52 that opens and closes the interior of the reservoir main body 51.

The cover 52 is closed with the left and right side walls 52a overlapping the outside (or inside) of the left and right side walls 51a of the storage tank main body 51, and when opened, it can prevent clams from being lost to the side, so they do not fall on the floor. Eliminates the inconvenience of picking up fallen clams.

6. Boundary rope (70).

When the mudflat and clams are disturbed and dispersed using the disruptor 10, the clams may escape the harvesting area, and a boundary rope 70 is included to prevent this.

The boundary rope 70 has a diameter that can prevent clams from being pushed and is installed in two rows on both left and right sides, and for example, the installation area is from the front of the disruptor 10 to the back of the feeder 40.

Boundary rope 70 is used via rope holder 71. The rope holder 71 is formed, for example, with a semicircular cross-section so that the boundary rope 70 can be inserted and coupled thereto, and is installed in a rotational or forward-backward manner on both left and right sides of the frame 60, respectively, so as not to protrude from the harvester 100 during normal times. When stored and used, it is switched according to the installation direction of the boundary rope 70 and moves the boundary rope 70 forward and backward when the harvester 100 travels.

7. Dispersion wing (80).

As shown in Figures 10 and 11, the dispersion wings 80 are designed to prevent clams that were not collected by the scraper 30 from being damaged by being pressed by the wheels of the traveling equipment 200, and move toward the rear from the center to both left and right. It has a "V" shape that slopes towards it, and both ends protrude further than the wheels of the traveling equipment 200.

The distribution wing 80 is connected to the frame 60 or the traveling equipment 200 in a way that can be lifted up and down, for example, a fixed pipe 81 fixed to the frame 60, etc., and is connected to the fixed pipe 81 so that it can be lifted up and down, and the bottom is a distribution wing. It is connected through a lifting pipe (82) connected to (80), and various methods such as hydraulic cylinders and handles are possible for raising and lowering the lifting pipe (82).

The lifting and lowering of the dispersing wing 80 includes height adjustment, that is, it can be used at various heights to disperse and protect clams in the tidal flat, and is placed on the tidal flat when not in use, so it does not interfere with the running of the shellfish collector 100.

The dispersion wing (80) can be either a flat type or a curved shape that is concave toward the front. The dispersion wing (80) with a curved cross section is more useful than the flat type in that it prevents clams from going over the top of the dispersion wing (80). This effect can also be achieved by tilting the upper part of the flat plate further forward than the lower part.

So far, the shellfish collector 100 has been described as being located in the front of the traveling equipment 200, but it is not limited to this and can also be installed at the rear of the traveling equipment 200.

The method of collecting clams using the shellfish collector according to the present invention is as follows.

1. Setting up the shellfish collector.

Mount the shellfish collector 100 on the mudflat, rotate the rope holder 71 toward the mudflat, and then install boundary ropes 70 on both the left and right.

The disruptor 10, aligner 20, scraper 30, and feeding screw 42 are set by connecting them to a driving source such as a hydraulic motor. Adjust the height of the aligner (20) and scraper (30).

2. Operation of shellfish harvester.

By operating the switch, the disruptor 10 sprays water at high pressure, the aligner 20 and the scraper 30 rotate, and the feeding screw 42 rotates.

3. Disturbance.

The disruptor 10 sprays water at high pressure on the mudflat to disturb the mudflat, disperse the clams, and cause the clams buried in the mudflat to rise to the surface of the mudflat.

Some of the clams disturbed and dispersed by the disruptor 10 may be pushed out of the harvesting area, but the boundary rope 70 prevents these clams from leaving the harvesting area.

4. Sort.

The aligner (20) passes through the area where the mudflats and clams are disturbed and dispersed by the disruptor (10), and in this process, the first and second sorting beads (21, 22) align the clams in the collection area with the central collection unit. Transfer and align with (24).

5. Collection.

The scraper (30) follows the place where the sorter (20) collects the clams, scoops out the clams, and puts them into the feeder case (41).

The washing water sprayer 46 sprays washing water onto the clams in the feeder case 41 to wash the clams.

6. Transfer and recovery.

As shown in FIG. 12, the shellfish collector 100 is raised through the boom of the traveling equipment 200, and the height at which the discharge portion of the feeder case 41 is higher than the storage bin 50.

When the feeding screw 42 of the feeder 40 is driven, the clams in the feeder case 41 are moved to the discharge part and are transferred to the storage tank 50 through the feeding hose 43 and stored in the storage tank 50. The feeding hose 43 stores clams by gravity-falling them due to the difference in height between the point connected to the discharge unit and the point corresponding to the storage bin 50.

7. Supply of clams.

When the storage bin 50 is filled with an appropriate amount of clams, the cover 52 of the storage bin 50 is opened to supply the clams to the sorter 300.

As shown in Figure 13, by applying the crusher 400 to the shellfish harvester of the present invention, waste shells can be crushed at the clam collection site. The crusher 400 is provided with a crushing space inside, and has an inlet at the top and a bottom. It includes a case 410 provided with an outlet, installed in the case 410, and one or more stages of crushing means 420 for crushing spent clam shells.

The crushing means 420 can be used in various ways, such as a method in which a plurality of crushing blades are rotatable on both sides, a ball mill method, and an impact method.

The crusher 400 can be installed in parallel with the storage tank 50 where the storage tank 50 is installed, or the storage tank 50 can be made removable and the storage tank 50 is separated from the traveling equipment 200 before being installed and used.

For example, as shown in FIG. 14, the traveling equipment 200 includes a support foot 220, and the storage bin 50 and the crusher 400 each include support foot insertions 53 and 430 to support the support foot 220. ) When collecting clams, a storage container (50) is installed and used, and when crushing spent clam shells, a crusher (400) is installed and used.
