Description

Technical Field

[0002] During the large-scale poultry breeding and slaughtering process, the carcass needs to be divided once to obtain a half-carcass or breast cover, and the half-carcass or breast cover needs to be divided twice, including picking large breasts, small breasts, and wishbones. Among them, for the picking of small breasts, the structure of the existing technology's automatic small breast picking device is too simple to perform fine processing on small breasts, resulting in poor quality and irregular appearance of the removed small breasts, and requiring secondary trimming later. The existing technology's device uses vertical transportation in the transportation method, and this transportation mode will affect the quality of the small breasts after separation when cutting and separating the small breast meat. In addition, the processing output of the existing technology's device is insufficient, the working efficiency is low, and multiple devices need to be configured to meet the output requirements, resulting in too high costs. Summary of the Utility Model

[0017] The working process of the automatic chicken breast fillet picking device of the present utility model is as follows:

[0018] Define the up, down, front and back of the breast cover, as Figure 13 shown, the wide side of the breast fillet faces forward, and the fitting position with the skeleton faces upward and is fixed on the breast cover loading component 26;

[0019] Step 1: The conveying chain 27 intermittently travels counterclockwise. When the breast cover passes through the predetermined position of the breast fillet tendon cutting module with the breast cover facing forward, the breast cover loading component 26 rotates 90 degrees, and the tendon cutting motor 5 drives the circular tendon cutting knife 3 to rotate to cut off the tendon connecting the breast fillet and the skeleton. At this time, the skeleton and the breast fillet are in a fitting state;

[0020] Step 2: The breast cover rotates 90 degrees driven by the breast cover loading component 26 to make the breast cover continue to face forward. When the conveying chain 27 intermittently travels counterclockwise through the rotary cutting knife mechanism in the breast fillet separation module, the driving reduction motor 13 drives the rotary cutting knife 15 to rotate to cut open the vertical joint surface position between the breast fillet and the skeleton to separate the breast fillet and the skeleton at this fitting position;

[0021] Step 3: When the conveying chain 27 intermittently travels counterclockwise through the non-powered inclined cutting knife mechanism in the breast fillet separation module, the inclined cutting knife 19 cuts open the inclined joint surface position between the breast fillet and the skeleton to separate the breast fillet and the skeleton at this fitting position;

[0022] Step 4: When the conveying chain 27 intermittently travels counterclockwise through the non-powered horizontal cutting knife mechanism in the breast fillet separation module, the horizontal cutting knife 23 cuts open the horizontal joint surface position between the breast fillet and the skeleton to separate the breast fillet and the skeleton at this fitting position;

[0023] Step 5: At this time, the breast fillet and the skeleton are basically in a separated state. When the conveying chain 27 intermittently travels counterclockwise and finally passes through the scraper 12, the scraper 12 separates and drops the breast fillets symmetrically distributed on the skeleton to complete the separation of the breast fillet and the skeleton.

[0024] The beneficial effects of the present utility model are summarized as follows:

[0055] For the automatic chicken tenderloin picking device of the present utility model, the up, down, front, and back of the breast cover are defined. As Figure 13 shown, the wide side of the tenderloin faces forward, and the bone-attaching part faces upward and is fixed on the breast cover loading member 26. The working process is as follows:

[0056] Step 1: The upper end of the breast cover unloaded from the broiler carcass is hung on the breast cover loading member 26. Springs, hooks, etc. are arranged on the breast cover loading member 26 to fix the loaded breast cover. Arrange the small breast tendon cutting module and the small breast separation module in sequence. The conveyor chain 27 travels intermittently counterclockwise. Before the breast cover passes in front of the predetermined position of the small breast tendon cutting module, the breast cover loading member 26 rotates 90 degrees. The piston rod end of the tendon cutting cylinder 6 contracts, driving the rotating rod 202 to rotate, so that the tendon cutting mechanism is lifted to the working position. At this time, the tendon cutting motor 5 drives the circular tendon cutting knife 3 to rotate, cutting off the tendon connecting the small breast and the skeleton. The skeleton and the small breast are in a fitting state at this time. When the work is completed, the piston rod end of the tendon cutting cylinder 6 extends to make the tendon cutting mechanism fall back to the original position;

[0057] Step 2: The breast cover rotates 90 degrees under the drive of the breast cover loading member 26 to continue moving forward. When the conveyor chain 27 travels intermittently counterclockwise through the predetermined position of the rotary cutter mechanism in the small breast separation module, the piston rod end of the separation cylinder 16 extends, lifting the rotary cutter mechanism. At this time, the drive reduction motor 13 drives the rotary cutter 15 to rotate, cutting open the vertical joint surface position between the small breast and the skeleton to separate the small breast and the skeleton at this fitting position;

[0058] Step 3: When the conveyor chain 27 travels intermittently counterclockwise through the non-powered bevel cutting mechanism in the small breast separation module, the bevel cutting knife 19 cuts open the bevel joint surface position between the small breast and the skeleton to separate the small breast and the skeleton at this fitting position;

[0059] Step 4: When the conveyor chain 27 travels intermittently counterclockwise through the unpowered horizontal cutter mechanism in the small breast separation module, the horizontal cutter 23 cuts open the position of the horizontal joint surface between the small breast and the skeleton, separating the small breast from the skeleton at this joint position;

[0060] Step 5: At this time, the state between the small breast and the skeleton is basically in a separated state. When the conveyor chain 27 travels intermittently counterclockwise and finally passes through the scraper 12, the scraper 12 separates and drops the small breasts symmetrically distributed on the skeleton, completing the separation of the small breasts from the skeleton.
