Abstract

PROBLEM TO BE SOLVED: To make it possible to feed a suitable amount of shellfishes into a sieve automatically, efficiently, naturally, and effectively irrespectively of the shapes, sizes, and kinds of the shellfishes to be sorted without encountering the problem that, when shellfishes, or the like, to be sorted are introduced into a hopper at a time, they usually tend to form a round heap in the hopper, and can not therefore be fed uniformly and smoothly into the sieve. SOLUTION: In a sorter wherein a sieve is formed under a hopper 1 in a slanting and swingable manner, a hopper support metal is fixed on the frame 2 of the sorter on one side of the hopper 1 and a hopper swing roll 12 is mounted on a hopper roll guide surface 11 on the other side of the hopper 1. The sorter is adapted so that a sieve frame 3 swings as the sorting proceeds and the swing displacement varies by adjustment of the angle of the hopper roll guide surface 11.

[Means for Solving the Problems] The technical means taken to achieve the above-mentioned object is, in claim 1, that a sieve is provided obliquely below a hopper for dropping shells, and the sieve is arranged so as to be swingable. Then, in a sorting machine that sorts shellfish while swinging the sieve,
The gist of the present invention is that a hopper swing amount adjustable device that can adjust the inclination angle is fixedly installed on the screen frame below the outlet of the hopper shell.
The gist of claim 2 is that a distributor is fixedly provided so that the width of the hinge plate can be adjusted to be narrowed and expanded from the center of the hopper toward the outlet of the shellfish. According to a third aspect of the present invention, one of the hoppers is fixed to the frame of the hopper rotation support bearing base and the other is fixed to the frame of the sorter. The gist is that fine adjustment of the hopper swing amount is possible.

[0005]

According to the above technical means, there are the following actions. (Claim 1) The swing of the hopper itself is adjusted according to the state of the shell or the like so that the angle of the hopper roll guide surface of the hopper swing amount adjustable device is adjusted according to the state of the shell or shell to smooth the supply flow of the shell or the like. (Claim 2) Even the helicoidal shellfish in the hopper is made uniform to make the flow smooth, and conversely, when the flow is too good, the appropriate distributor width is adjusted to be narrowed and expanded to promote the supply to an appropriate sieve. (Claim 3) One of the hoppers is provided with a hopper rotation support bearing stand fixed to the sorter frame body, and one of the hoppers is fixed to the sorter frame body. The angle of the hopper roll guide surface of the hopper swing amount adjustable device for mounting and supporting the hopper enables fine adjustment of the hopper swing amount.

By adjusting the angle of the hopper roll guide surface 11 and fixing the hopper swing amount adjustable device 16 to the sorting machine frame 2, it is possible to finely adjust the hopper swing amount without swinging even during work. As a swing source of the hopper 1, the arms of the sorting machine frame swing intermediate rotation shaft 27 are combined with each other, and the hopper swing rotation shaft 31 of the hopper support arm 30 is used to sort the sorting machine frame swing intermediate rotation shaft 27.
The swing can be transmitted more.

When the shells are sorted by size, a hopper roll guide surface 1 is used by using a sorting plate 8 suitable for each shell.
The angle adjustment of 1 makes it easy to adjust while watching the sorting situation during shellfish selection, and the fine adjustment allows the shellfish to flow smoothly, which reduces the time required for any size sorting operation and does not damage the shellfish. The shellfish can be selected accurately and accurately. Further, the sorting operation can be performed only by removing the sorting plate removing cover lock 25 and replacing the sorting plate 8 suitable for the shells for sorting small shells to large shells with one sorter.

[0010]

Since the present invention is constructed as described above, it has the following advantages. (Claim 1) Regardless of the shape, size, and type of the selection shell, the amount of movement in the hopper can be varied efficiently without waste regardless of the shape, size, and type of the selection shell by supplying the selection shell to the sieve. As a result, the supply of the sieve becomes uniform and the sorting work efficiency is improved. (Claim 2) Slippers and the like that easily slip off stay in the hopper by increasing the width of the sorter, and by reducing the width of the sorter, shells with a lot of deposits, etc. that are difficult to slip and cannot be smoothly supplied to the sieve, etc. Can also be supplied according to the condition, which improves work efficiency. Also, since the swinging amount adjusting device is fixedly installed in the sorting machine itself, the shellfish floats up during sorting, so there is almost no shellfish that blocks the sorting hole of the sorting board. Even if the holes are closed, the selected shellfish will float up and move forward with proper adjustment, and the live shellfish will be eliminated smoothly. (Claim 3) Since the hopper swing amount adjustable device is fixedly mounted on the frame of the sorting machine, there is no swing even during work, and fine adjustment of the hopper swing amount is possible without difficulty so that the work can be performed more efficiently.
