Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a sorting device that is particularly useful for sorting shellfish such as shallow clams, clams, and clams.

[Prior art and its problems]

When shipping collected shellfish, cleaning and sorting are performed as pre-treatment.

Shellfish are sorted using sieves to separate them into large, medium, and small sizes, but the sizes vary slightly depending on the production area, so it is necessary to change the sieve screen depending on the production area and type of shellfish received. There is.

However, since conventional automatic sorting equipment has a structure in which the sieve screen is fixed with bolts and nuts, it takes time for female workers to replace it, and there are many problems such as losing bolts and nuts during replacement work. .

Therefore, this invention aims to provide a sorting device that is particularly easy to use not only in the case of a single-stage type but also in the case of a multi-stage type.

[Means to solve the problem]

This invention is constructed as follows in order to solve the above problems.

That is, in this invention, a swinging frame driven by a drive device is provided on the machine frame, a sieve screen is placed on a receiving piece provided on this swinging frame, and a stop hole is formed in the side of the sieve screen and the swinging frame, respectively. In addition to providing a stopper on the outer surface of the swing frame,
The sieve screen is fixed to the swing frame by inserting a stop pin having a lock handle that engages with the stopper into the stop hole.

[Effect]

According to this structure, the sieve screen can be easily removed by removing the stop pin, and the lock handle is engaged with the stop piece by inserting the stop pin into the stop hole provided on the side of the swing frame and the sieve screen. The sieve screen can be securely fixed by simply letting the screen slide, and even female workers can easily replace the sieve screen.

〔Example〕

The drawings show an embodiment of this invention, with FIG. 1 being a side view and FIG. 2 being a sectional view showing the internal structure.

This embodiment is a three-stage automatic sorting device, large,
Medium and small shellfish and garbage (including small shellfish that cannot be sold as products)
The purpose of this is to select the following items.

In the figure, reference numeral 1 denotes a swing frame driven by a crank mechanism 10 rotated by an electric motor (not shown), and a machine frame 2 is provided with elastic plates 11, 11 (rubber plates were used in the embodiment). It is suspended through.

Inside the swing frame 1, there are receiving pieces 3 on the front and back (left and right in the figure).
3 are provided in three stages, and three sieve screens 4 having successively smaller lengths and gaps are placed on them so as to be inclined.

Each sieve screen 4 is provided with a stop piece 5a having stop holes 5 at four places in the front and back, as shown in FIGS. 3 and 4, and stop holes 6 that match the stop holes 5 are provided. It is provided on the side surface of the swing frame 1.

As shown in FIGS. 1 and 4, an L-shaped stopper piece 7 is provided on the outer surface of the swing frame 1 in the vicinity of the stopper hole 6, and a stopper pin 9 passing through both the through holes 5 and 6 is provided with an L-shaped stopper piece 7. It is configured to be fixed by twisting.

The locking pin 9 is designed so that a lock handle 8 provided thereon is engaged with the locking piece 7 so that it will not come off.

Guide chutes 12, 13, 14, and 15 are attached to the ends of the machine frame 2 in an X shape.

Each sieve screen is made up of round rods attached in the shape of a crosspiece in the swinging direction, which is designed to facilitate the flow of shellfish.

Now, when the switch 16 is turned on to start the drive device (housed on the right side of the machine frame 2 in the figure), the swing frame 1 swings from side to side via the crank mechanism 10.

Next, when the shellfish on the pedestal 17 is dropped onto the swinging frame 1,
Shellfish flow on the sieve screen 4 provided at an angle, and shellfish whose mesh size is smaller than the gap between the bars in the embodiment fall downward and pass through the guide chute 1.
2, 13, 14, sorted by large, medium and small,
Garbage (including small shellfish that cannot be used as products) falls into the guide chute 15, and the containers 1 placed below each fall into the guide chute 15.
It is stored in 8.

When replacing the sieve screen 4, turn off the switch 16 to stop the drive device, rotate the lock handle 8 to remove it from the stopper 7, and then remove the stopper pin 9.

In this way, the sieve screen 4 is simply placed on the receiving pieces 3, 3, and can be easily removed.

If you want to stop a new sieve screen 4, just do the opposite operation.

In the embodiment described above, the sieve screen has three stages, but it may also have one or two stages.

[Effect of idea]

As described above, according to this invention, the sieve screen can be replaced extremely easily, so it is possible to change the type of shellfish,
This is an excellent practical sorting device because even women can easily replace the sieve screen of the sorting device, which is often replaced depending on the production area.

Of course, this invention is not limited to a shellfish sorting device.
