Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention utilizes the characteristics of the smooth and hard shell of seashells to adjust the rotational speed of the roll shaft and the roll The inclination angle of the shaft, the length of the roll shaft, the gap between the roll shafts, and the diameter of the roll shaft. The present invention relates to a shellfish grading device for sorting shellfish into grades.

0002

[Conventional technology]

Conventional shellfish grading equipment consists of a rotatable roll structure; The body is equipped with a cylindrical material tank made of four layers of curved sheet metal of different sizes. In addition, multiple through holes are drilled on the material tanks up to the third layer, and the innermost material The through holes in the tank are the largest, and the through holes in the third layer material tank are the smallest. When shellfish are introduced from the center of the roll structure, large shellfish are thrown in the direction of inclination of the roll. Small shellfish flow out and enter the second layer material tank through the through hole, and then small shellfish enter the second layer material tank. The material is separated into the third layer material tank through the through hole, and in this way Shellfish were classified into four classes.

0003

[Problem that the invention attempts to solve]

In conventional roll-type grading devices, the size of the through hole is fixed. Because the size of shellfish during the breeding and non-breeding seasons is so different, constant penetration is necessary. The size of the pores cannot be used to classify shellfish in these seasons. Matagai When the roll structure is graded, it gets caught in the through hole and the roll rotates upwards. There is a problem that shellfish are damaged when they fall, and the rotating roll structure When the shellfish enters the next layer through the through hole approaching the outlet, the length of the cylindrical material tank is too short, it is not possible to perform sufficient grade classification, and the accuracy of grade classification cannot be achieved. There is a problem of lack of sexuality.

0004 The purpose of this invention is to eliminate the drawbacks of conventionally known grading devices, and to The gap between both roll axes can be adjusted using the adjusting device, allowing for accurate handling of shellfish of various sizes. Shellfish can be graded quickly and easily without damaging the shellfish. The objective is to provide a class sorting device of the same type.

[0005]

[Means to solve the problem]

The shellfish grading device according to the present invention includes at least one grading unit. The grading unit is equipped with a material tank with an open top and an inclined bottom. The tank has an outlet at the sloping end of the bottom and one side adjacent to the sloping end. At least one pair of roll shafts are installed in the material tank at regular intervals and in opposite directions. The gap between the pair of roll axes can be adjusted by attaching the roll to one side of the material tank. The grade sorting unit is installed diagonally on the outer frame so that the discharge port provided is at the bottom end. be.

[0006]

[Effect]

The shellfish introduced through the upper opening of the material tank are sorted by grade based on the gap between the roll axes. Large shellfish lose their own weight and load due to the inclination angle of the roll axes that rotate in opposite directions. The roll shaft rotates to discharge small shellfish from the outlet on one side, and small shellfish are passed through the gap between the roll shafts. It falls to the sloping bottom and is supplied to the next grade sorting unit from the outlet at the sloping bottom. Ru.

[0009] Figures 5 and 6 are a combined perspective view and an exploded perspective view of the shellfish grading device of the present invention. The shellfish grading device includes two grading units 1 and 2. Knits 1 and 2 have two bolts 50 and 51 passed through their respective material tanks 20 and 21. and screwed together with nuts 531 and 541, and with bolts 50 and 51 as fulcrums, separate the two grades. The separate units 1 and 2 are fixed to the support plates 53 and 54 of the outer frame 52, and a corner is attached to one end of the outer frame 52. It is equipped with angle adjustment handles 55, 56, and when the angle adjustment handles 55, 56 are turned, the screw The vertical movement of the grading units 1 and 2 can be adjusted along the rods 57 and 58, and the threaded rod 5 7 and 58 are mutually connected to the material tanks 20 and 21 by end rod bearings (not shown). The inclination angles of the material tanks 20 and 21 of the grading units 1 and 2 can be controlled by connecting them, and the external Shellfish are introduced into the space between the roll shafts 10 and 11 through the input port 64 provided at the upper end of the frame 52. When the roll shafts 10 and 11 rotate, shellfish are generated due to the angle of inclination. Using the gravitational acceleration and the frictional relationship between the roll shafts 10 and 11, the shellfish are They are arranged in a line, and the gap between the roll shafts 10 and 11 is used as a standard for grade classification. Smaller shellfish fall through the gap below the roll shafts 10, 11, and larger shellfish fall below the roll shafts 10, 11. The shellfish are conveyed along the inclined direction of the roll shafts 10 and 11, and are transferred to the grading unit 1. Shellfish with a small thickness slide out from the discharge port 202, and the gap between the grading unit 1 is removed. After falling below the roll shafts 10, 11, the outlet 206 of the bottom 204 of the material tank shellfish flows into grading unit 2, after which shellfish with small thickness are further graded. It falls into the gap between the roll axes 12, 13 of the unit for further grading. The bottom of the outer frame 52 is equipped with a leg stand 59 and a transportation wheel 60, which can be used to classify the grade according to the present invention. It has the function of supporting and transporting the equipment.

0010 If all the shellfish go through grade sorting unit 1, half of the total number of shellfish will be of small and medium grade. When the amount of shellfish becomes insufficient, small and medium-sized shellfish are passed through the roll shaft of the second grade sorting unit 2. These shellfish are also sorted into half of what they were when entering grading unit 2. Therefore, as shown in FIG. 7, a first grade sorting unit equipped with two sets of roll shafts 10 and 11 1, and furthermore, the input port of the grade sorting unit 1 is connected to two input ports 61 and 62. The discharge ports are combined into one discharge port 63, and the row of the second grade sorting unit 2 is Since it is provided on the double shafts 12 and 13, its separation capacity is doubled. Furthermore, roll axis 1 By increasing the water injection system 73 above 0.11 as shown in FIG. It is possible to grade worms or shallow worms.

[0011]

[Effect of the idea]

Since the present invention has the above-mentioned configuration, the roll shaft can be rotated and the roll shaft can be removed. The attached grade sorting unit can be tilted in an adjustable manner to separate shellfish, preventing damage to shellfish. You can quickly and easily grade shellfish without having to Adjustable spacing allows for accurate classification of shellfish of various sizes. can become.
