[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention utilizes the characteristics of a smooth and hard shell to determine the rotation speed of the roll shaft, the inclination angle of the roll shaft, the length of the roll shaft, the gap between the roll shafts, and the roll. The present invention relates to a shellfish classifying device for classifying shellfish based on the diameter of a shaft.

[0002]

2. Description of the Related Art A conventional shellfish classifying device comprises a rotatable roll structure, and the roll structure is provided with a cylindrical material tank in which four sheet metals having different sizes are curved and combined into four layers. A plurality of through holes are formed on the material tank up to the third layer, the through hole of the innermost material tank is the largest, and the through hole of the third layer material tank is the smallest,
When shellfish are loaded from the center of the roll structure, large shellfish flow out in the direction of the roll's inclination, small shellfish take through holes to enter the second-layer material tank, and next small shellfish go through the through holes to form three layers. The material was sorted into the eye material tank, and in this way shells were sorted into four grades.

[0003]

[Problems to be Solved by the Invention] Since the size of the through-hole is fixed in such a conventional roll-type classification device, the sizes of the shellfish in the breeding season and the non-breeding season are very different. Therefore, with a certain size of the through hole, it is not possible to classify the shellfish in these seasons. There is also a problem that shellfish are caught in the through holes during the classification work of the roll structure, and the shells are damaged when the roll rotates upward and falls, and in the rotary roll structure, the shells approach the outlet. When entering the next layer through the through hole, the length of the cylindrical material tank is too short to perform sufficient grading, and there is a problem that the grading is not accurate.

The object of the present invention is to eliminate the drawbacks of the conventionally known grading devices, and it is possible to adjust the clearance between both roll shafts by means of a bearing pedestal adjusting device to accurately classify shellfish of various sizes. SUMMARY OF THE INVENTION An object of the present invention is to provide a shellfish grading device that can be quickly and easily carried out without damaging the shellfish.

[0005]

SUMMARY OF THE INVENTION A shellfish grading device according to the present invention is provided with at least one grading unit, and the grading unit includes a material tank having an open top and an inclined bottom. A discharge port is formed in each of the tanks at the slanted end of the bottom and one side adjacent to the slanted end, and at least a pair of roll shafts are mounted in the material tank so as to be rotatable at regular intervals in mutually opposite directions. The grade separation unit is obliquely attached to the outer frame so that the gap between the pair of roll shafts can be adjusted and the discharge port provided on one side of the material tank is at the lower end.

[0006]

[Function] The shellfish charged from the upper opening of the material tank are classified by the gap between the roll shafts, and the large shellfish is moved by its own weight and the rotation of the roll shaft due to the inclination angle of the roll shafts rotating in opposite directions. The small shellfish are discharged from the discharge port, fall through the gap between the roll shafts to the inclined bottom portion, and are supplied to the next classification unit from the discharge port of the inclined bottom portion.

Therefore, the shellfish are arranged linearly by using the gravity acceleration generated by the inclination angle and the frictional relationship between the roll shafts 10 and 11 and the gap between the roll shafts 10 and 11 is used as a standard for classification. The shells having a small thickness fall below the roll shafts 10 and 11 through the gap, and the shells having a large thickness are conveyed along the inclination direction of the roll shafts 10 and 11, and the discharge port 202 of the classification unit 1 is discharged. Gliding from The shellfish having a small thickness falls below the roll shafts 10 and 11 with a gap between the grade sorting unit 1 and then flows into the grade sorting unit 2 through the discharge port 206 of the bottom portion 204 of the material tank, and then has a small thickness. The shellfish further falls into the gap between the roll shafts 12 and 13 of the grading unit for further grading. The bottom of the outer frame 52 is provided with a pedestal 59 and a transportation wheel 60, which has the function of supporting and carrying the classification device of the present invention.

When all of the shellfish go through the grade sorting unit 1, less than half of the total number of small and medium grade shellfishes are passed, and when the small and medium grade shellfish are passed through the roll axis of the second grade sorting unit 2, these Since shellfish are also divided into half when entering the grade classification unit 2, as shown in FIG. 7, the first grade classification unit 1 having two sets of roll shafts 10 and 11 is provided, and the grade classification unit 1 is further provided. The inlet is divided into two inlets 61 and 62, and the outlet is one outlet 6.
Roll shaft 1 of the second classification unit 2 combined with 3
Since it is equipped on the 2nd and 13th, its sorting ability is doubled. Further, when the water injection system 73 is increased above the roll shafts 10 and 11 as shown in FIG. 8, it is possible to perform classification of lighter weight or shallow weight.
