Problems solved by technology

[0012] However, in order to smoothly perform the screening work without causing the fish 10 to pop out, it is necessary to provide guide rollers 1204 and guide plates 1206, and to provide an interval adjustment that finely adjusts the interval between a pair of rotating rollers 1202 constituting one screening section. part, so there are disadvantages of complex structure and increased volume of the device
[0013] In addition, when screening fresh and alive fish 10, in order to ensure the survival of fish 10, the screening work needs to be carried out rapidly, but when using the screener of the prior art, there is the shortcoming that cannot carry out fast screening

[0047] Fig. 3a is a perspective view showing the structure of the screening unit 110 according to the first embodiment of the present invention, Figure 3b It is a side sectional view showing the arrangement state of the screening unit 110 .

[0048] Figure 3a and Figure 3b As shown, the screening part 110 includes a pair of upper rollers 112a arranged in parallel with each other and one lower roller 112b arranged below the pair of upper rollers 112a.

[0049] Generally, the rotation axes of the three rollers 112a and 112b are all parallel, and the screening part 110 is inclined at a certain angle with respect to the ground. However, in the case of fish such as eels, even if the screening unit 110 is not inclined, it can move by itself and slide down between the rollers 112a and 112b. Therefore, even if the screening unit 110 is arranged parallel to the ground, a predetermined screening effect can be achieved. .

[0062] FIG. 6a is a perspective view showing the structure of the screening unit 210 according to the second embodiment of the present invention, Figure 6b It is a side sectional view showing the arrangement state of the screening unit 210 .

[0063] In the rollers 212a and 212b used in the second embodiment, the rotation axes of the three rollers 212a and 212b are parallel and inclined at a certain angle with respect to the ground, and all rotate in the same direction.

[0064] However, the three rollers 212a and 212b are not in a cylindrical shape but in a truncated cone shape whose cross-sectional area gradually decreases in the longitudinal direction, which is different from the first embodiment.

[0065] It is desirable that the cross-sectional area of ​​the rollers 212a, 212b decreases with the downward direction of the inclination.

[0066] In this state, when the fish 10 is put between the two upper rollers 212a, after the fish 10 is put through the guide section G a...

[0072] Cylindrical rollers 312a and 312b are used in the screening unit 310 according to the third embodiment, and the rotation axis of the upper roller 312a and the rotation axis of the lower roller 312b are opened at a certain angle with respect to the horizontal plane. The central axes of the two upper rollers 312a are arranged in parallel with each other on the same plane, and the central axes of the lower rollers 312b are arranged to be inclined at a predetermined angle with respect to the plane on which the central axes of the two upper rollers 312a are located.

Abstract

The present invention provides a fish sizer, including two upper rollers and one lower roller, capable of quickly and accurately screening the fish and shellfish according to the size, such as shrimp, anchovy, flatfish and oyster etc. The fish sizer has a screening part, including two upper rollers and one lower roll collocated on the lower of the two upper rollers; a driving part, ensuring the upper rollers and the lower roller rotate; and a frame, for fixing the screening part; the central axis of the lower roller is located on the vertical lower of the middle part of the central axis of the upper rollers. Thus, the invention not only screens the processed fish, but also screens the fresh fish according to the size quickly and accurately, and having advantages of processing effective screen work irrelative to the working environment and the location.

Description

technical field [0001] The present invention relates to a fish screener, which is composed of two upper rollers and one lower roller, and can quickly and accurately screen fish and shellfish such as shrimp, anchovies, flounders, and oysters by size. Background technique [0002] The price of fish such as shrimp and anchovies varies with size, and should be distributed according to length or thickness. To this end, various forms of filters are disclosed. [0003] Screeners disclosed in the past include "roller screen vibrating in the lateral direction" (Korean Patent No. 465405), "roller screener" (Korean "Roll Screening Device" (Korean Patent No. 642077), "screener" (Korean Patent No. 652225), and the like. [0004] Figures 1a to 1d It is a diagram showing the structure of Patent No. 642077 "Rotating Roller Screening Device" (hereinafter referred to as "Prior Art"). The motors 1302 rotate in opposite directions between the rotating rollers 1202, and are sorted by size at...
