Description

Technical Field

[0001] This invention relates to a scallop shell removal device, and more specifically to an automatic scallop shell removal device. Background Technology

[0002] Scallops are an important economic aquatic product. The crucial preliminary step in their processing—evenly splitting the scallop shells while preserving the adductor muscle—is essential for subsequent extraction, purification, and cooking. Currently, this process relies heavily on manual labor, resulting in low efficiency, high costs, and poor product consistency. Therefore, a scallop splitting device is needed that can separate the upper and lower shells of the scallop while maintaining a natural connection between the adductor muscle and one side of the shell, while also achieving high production efficiency and low breakage rate. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic scallop shell removal device. This device enables automated, low-damage shell removal of scallops, effectively improving both shell removal efficiency and quality. It can process scallops of various sizes, maintaining a natural connection between the adductor muscle and one side of the shell while preserving the freshness of the adductor muscle and internal tissues.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic scallop shell removal device, comprising a frame, a chain drive device, an adjustable-spacing infrared heating device, a heating tube reflector, a shell removal device, a scallop clamping unit, and a collection trough, characterized in that: the chain drive device is located directly above the frame and is horizontally arranged; sprocket shaft bearings are installed on both sides above the front and rear ends of the frame; the sprocket shaft is installed on the sprocket shaft bearings; the sprockets are located at both ends inside the frame and installed on the sprocket shaft; a chain with lugs is fitted onto the sprockets; a chain drive motor is installed on one side of the outer front end of the frame and connected to the sprocket shaft via a coupling; the adjustable-spacing infrared heating device is located above the chain drive device; the heating tube reflector is installed on the frame and covers the infrared heating tube; the shell removal device is located at the rear end of the adjustable-spacing infrared heating device; the scallop clamping unit is connected to the lugs chain at both ends and is arranged in a full circle on the lugs chain; the collection trough is installed at the rear end of the frame.

The chain drive device 2 is located directly above the frame 1 and is horizontally arranged. A sprocket shaft bearing 202 is installed on both sides above the front and rear ends of the frame 1. A sprocket shaft 203 is installed on the sprocket shaft bearing 202. Sprockets 204 are located at both ends inside the frame 1 and are installed on the sprocket shaft 203. A chain with lugs 205 is fitted onto the sprockets. On frame 1, chain drive motor 201 is mounted on the outer side of the front end of frame 1 and connected to sprocket shaft 203 via coupling 206; adjustable spacing infrared heating device 5 is located above chain drive device 2; heating tube reflector 4 is mounted on frame 1 and covers infrared heating tube 512; shell removal device 6 is located at the rear end of adjustable spacing infrared heating device 5; scallop clamping unit 3 is connected at both ends to eared chain 205 and is arranged in a full circle on eared chain 205 at intervals; collection trough 7 is mounted at the rear end of frame 1.

[0010] like Figure 2As shown, the adjustable-gap infrared heating device 5 consists of a perforated plate 501, a heating device mounting base 502, a slide rail 503, a slide table 504, a lead screw nut 505, a lead screw 506, a stepper motor 507, a clamp coupling 508, a fixing plate 509, bolts 510, a fixing clamp 511, and an infrared heating tube 512. The heating device mounting base 502 is fixedly connected to the perforated plate 501 mounted above the frame 1 and is located below the perforated plate 501. The slide rail 503... The lead screw 506 is fixed on the heating device mounting base 502. The slide table 504 is mounted on the slide rail 503. The stepper motor 507 is connected to one end of the lead screw 506 through the clamp coupling 508. One end of the lead screw nut 505 is mounted on the slide table 504, and the other end is mounted on the fixing plate 509. The middle part is threaded and fitted onto the lead screw 506. The fixing clamp 511 is connected to the fixing plate 509 by bolts 510. The infrared heating tube 512 is mounted on the fixing clamp 511 at both ends.

[0011] like Figure 3 As shown, the upper shell removal device 6 consists of a crank-rocker arm mounting base 601, a crank-rocker arm drive motor 602, a rocker arm bearing 603, a rocker arm shaft 604, a crank 605, a connecting rod 606, a rocker arm 607, an upper shell release lever 608, and a fastener 609; the crank-rocker arm mounting base 601 is bolted to both sides of the rear end of the frame 1; the crank-rocker arm drive motor 602 and the rocker arm are mounted at the rear end of the crank-rocker arm mounting base 601. A rocker arm bearing 603 is provided, with the crank-rocker drive motor 602 fixed at the left end and the rocker arm bearing 603 fixed at the right end; a rocker arm shaft 604 is mounted on the rocker arm bearing 603; one end of the crank 605 is connected to the crank-rocker drive motor 602, and the other end is connected to the middle of the rocker arm 607 via a connecting rod 606; the lower end of the rocker arm 607 is connected to the rocker arm shaft 604; and the upper housing lever 608 is mounted on the upper end of the rocker arm 607 via a fastener 609.

[0012] Working principle: The scallop is placed on the scallop clamping unit 3. Depending on the size of the scallop, the stepper motor 507 rotates the lead screw 506, causing the lead screw nut 505 to move left and right on the slide rail 503 along the slide table 504. The fixing clamp 511 is connected to the fixing plate 509 fixed on the lead screw nut 505 by bolts 510, driving the infrared heating tube 512 to move left and right, so that the infrared heating tube 512 can completely cover the adductor muscle. When the infrared heating tube 512 starts heating, the chain drive motor 201 drives the lug chain 205 to rotate around the sprocket shaft 203. The chain transmission device 2 transports the scallop clamping unit 4 to the adjustable-gap infrared heating device 5 for heating, realizing the separation of the upper shell from the adductor muscle and the natural connection of the lower shell to the adductor muscle. Afterwards, the scallops leave the adjustable-spacing infrared heating device 5 and are transported to the shell-removing device 6. The crank-rocker drive motor 602 drives the crank 605 to rotate, which in turn drives the rocker arm 607 to swing via the connecting rod 606. The rocker arm 607 drives the shell-removing lever 608 to peel off the shell, thus separating the shell from the entire scallop. Under the action of the chain drive device 2, the scallops are finally transported to the collection tank 7.

[0013] This embodiment is merely an illustration of the concept and implementation of the present invention and is not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
