TH3774U - Fish sorting machine - Google Patents

Abstract

The DC60 fish sorting machine, as described in this invention, is a partial structural improvement of the patented shrimp sorting machine (patent number 2357), particularly in the fish conveyor belt assembly. The central and side sections of the conveyor belt are fitted with pressure plates to prevent the belt from lifting. Each fish receiving tray is fitted with a corresponding number of conveyor belts. Behind each receiving tray are impact plates that guide the sorted fish into the conveyor belt for further transport. Additionally, the upper part of the sorting system has several fish troughs to help align the fish before they enter the sorting rollers. At the lower end of each trough are several guide plates to direct the fish to be sorted between pairs of sorting rollers. This fish sorting machine, as described in this invention, is a partial structural improvement of the patented shrimp sorting machine (patent number 2357), especially in the fish conveyor belt assembly. The central and side sections of the fish conveyor belt are fitted with pressure plates to prevent the belt from lifting. Each fish tray is installed according to the number of conveyor belts, and behind each tray are impact plates. These plates guide the size-sorted fish onto the plates, causing them to move along the conveyor belt and be transported out of the sorting machine. Additionally, at the beginning of the sorting section, several fish troughs are installed to arrange the fish in a long line before they enter the sorting rollers. At the bottom end of each trough, several guide plates are installed to direct the fish to be sorted between pairs of sorting rollers.

Claims (7)

1. Fish sizing machine consists of a fish receiving tank (1) in which a conveyor belt (2) of belt width is the same as the width of the fish receiving tank (1), which is installed at an upward angle to convey the fish packed on the conveyor belt (2) to move up into the sizing process. The conveyor belt (2) has a fin-like, stepped belt design. The conveyor belt (2) is driven by a drive path installed on one side of the upper edge of the conveyor belt (2). The drive path transmits power through a power transmission path to drive the shaft of the conveyor belt (2), causing the conveyor belt (2) to convey the fish up from the fish receiving tank (1). The sizing unit (9) is installed on a support frame (10) in which the width is the same as the width of the conveyor belt (2) and consists of at least one pair of sizing rollers (12) that work in opposite directions. The sizing rollers (12) are installed on the support frame (10) at an downward angle when measured from the horizontal. The characteristics of the sizing rollers (12) are that they are progressively smaller, with the diameter and length of the rollers decreasing in stages according to the size of the fish to be sizing. At the beginning, the diameter and length of the sizing rollers (12) are larger and longer, and the diameter and length decrease in order. The body of the sizing rollers (12) has deep grooves (14) in the body of the rollers (12) on both sides in opposite positions. The drive unit (16), which drives the sizing unit (9), is installed at the beginning along the width of the sizing unit (9). The belt support rods (19) are installed along the width of the support frame (10). The belt support platform (19) has slots for inserting a number of fish-out conveyor belts (20) arranged parallel to each other. The fish-out conveyor belts (20) that are adjacent to each other are arranged in an alternating manner to send fish out on opposite sides. The fish-out conveyor belts (20) can slide in and out within these slots, with specific characteristics as follows: In the center and on both sides near the rear edge of the fish receiving tank (1) are clamp plates (6) that press down on the conveyor belt (2) to prevent it from lifting. The lower edge of the clamp plate (6) is pressed down on the conveyor belt (2), and the upper edge of the clamp plate (6) is attached to a support frame (7) that is laid across the width of the upper edge of the fish receiving tank (1). At the beginning of the sorting unit (9) are several fish sorting troughs (11) to help arrange the fish in a long line before moving into the sorting rollers (12). The two side fish sorting troughs (11) are angled inward, and the fish sorting troughs (11) between the two side troughs (11) are arranged parallel to each other in length. At the bottom end of each fish sorting trough (11) are several guide plates (13) corresponding to the number of fish sorting troughs (11) to help guide the fish. The required sizing flows down between each pair of sizing rollers (12), each of which the control plates (13) are arranged in a parallel manner along their length. 2. Fish sorting machine, according to claim 1, in front of the fish receiving tank (1) shall be a fish support platform (8) on which the top of the fish support platform (8) shall be sloped down from the front edge to the back edge to be used as a support for the fish before they are moved into the fish receiving tank (1). 3. Fish sizing machine, according to claim 1 or 2, in which the upper and lower sizing unit (9) shall have wheels (17) and wheels (18) mounted on either side of the upper and lower sizing heads, respectively, for adjusting the spacing of the pairs of sizing rollers (12) to the appropriate spacing for the size of the fish to be sizing. Between the upper pair of wheels (17) and the lower pair of wheels (18) shall be screws on the upper and lower receiving platforms of the sizing rollers (12). 4. Fish sorting machine, according to any one of the claims 1 through 3, in which at the bottom of the sorting unit (9) there shall be fish trays (21) of each number according to the number of fish conveyor belts (20), in which each fish tray (21) shall be mounted along the width of the sorting unit (9) in a forward-tilting manner, in which the upper edge of each fish tray (21) shall be fixed along the width at the beginning of each sorting roller (12) and the lower edge of each fish tray (21) shall be fixed along the width at the front edge of the fish conveyor belt (20). 5. Fish sorting machine, according to any one of claims 1 through 4, on the back of each fish receiving tray (21) is an impact plate (22) to be used for the sorted fish to flow against each impact plate (22) to move along the conveyor belt (20), where the top edge of each impact plate (22) is attached along the width in front of each subsequent fish receiving tray (21) and the bottom edge of each impact plate (22) is attached along the width behind the conveyor belt (20). 6. Fish sorting machine, according to any one of the claims 1 to 5, at the very end of the sorting unit (9), located on the side of the rear edge of the final fish conveyor belt (20), will be a barrier plate (23) which will be installed on the edge along the width of the final fish conveyor belt (20) to be used as a place for the sorted fish to move into so that they move along the fish conveyor belt (20). 7. Fish sorting machine, according to any one of claims 1 through 6, on both sides of the front of the support structure (10) there shall be a ladder (24) which shall be used for maintenance personnel to ascend along the side walkway (25) and the front walkway (26) which are connected to both sides and the front of the support structure (10).
