Abstract

A fish processing apparatus includes a casing in which are respectively mounted a brushing unit, a clamping unit, a pushing unit, a cutting unit, and a driving unit. The brushing unit includes two scraping brushes that are mounted in a manner to overlap each other. Each scraping brush includes an axle on which are attached a plurality of flexible bristles respectively terminating in a scraping portion. The rotation of the scraping brushes removes the scales of the fish body. The clamping unit is mounted at a location between and below the two scraping brushes to receive the fish body, and the pushing unit is placed below the clamping unit to push the fish body toward the cutting unit that cuts the fish body and removes its viscera.

Claims

1. A fish processing apparatus for processing a fish body, comprising

a casing;

a brushing unit, mounted in the casing, the brushing unit comprising two scraping brushes facing each other, each of the scraping brushes having an axle thereon, the two scraping brushes respectively having a plurality of flexible bristles, the flexible bristles each having a scraping portion, and the two scraping brushes being mounted overlapping each other;

a clamping unit, mounted at a location between and below the two scraping brushes, and having two clamping arms that are mounted facing each other, an end of each of the clamping arms being respectively pivotally connected to the axle of each of the scraping brushes so that the two clamping arms are capable of closing or opening relative to each other;

a pushing unit, mounted below the clamping unit;

a cutting unit, mounted at one side of the pushing unit and having a rotary cutting tool and at least a scraping ring used to remove a viscera of a fish body; and

a driving unit, connected to the respective axles of the scraping brushes and to the cutting unit.

2. The apparatus of claim 1, wherein the casing has an insert opening and a retrieval opening, and a bottom side of the casing has a plurality of support pads.

3. The apparatus of claim 1, further comprising two actuating rods respectively being connected with an end of the each clamping arm, and two actuating toothed wheels respectively being connected to another end of the each clamping arm and the two actuating toothed wheels engaging each other.

4. The apparatus of claim 1, wherein the pushing unit has a pushing plate, two connecting rods respectively connected with two opposite portions of the pushing plate, one oscillating bar further being connected with another end of the connecting rod and the one oscillating bar having one end pivotally connected to the casing according to a flexible manner, the pushing unit pushing the fish body toward the cutting unit.

5. The apparatus of claim 1, further comprising a rotary axle being connected with the cutting tool and the driving unit, a fixing plate with a conical surface being respectively mounted at two sides of the cutting tool, the scraping ring being placed at an outer side of the fixing plate, the scraping ring being made of plastics and having at least a protruding portion, a plurality of locking elements being used for securing the fixing plate being attached to the cutting tool.

6. The apparatus of claim 1, further comprising a receiving tray having an inclined section which is mounted below the cutting unit, a high portion of the inclined section being vis-à

-vis the cutting unit.

7. The apparatus of claim 1, wherein the driving unit has a motor, a first belt/wheel assembly being connected with the motor and a first toothed wheel being connected with the first belt pulley assembly, a second toothed wheel engaging the first toothed wheel, a second belt pulley assembly being connected with the first wheel and the axle of the one scraping brush, a third belt pulley assembly connected with the second toothed wheel and another axle of the another scraping brush.

8. The apparatus of claim 7, further comprising a fourth belt/wheel assembly and a transmission strip respectively being connected with the second toothed wheel and the rotary axle of the cutting unit.
