Description

Technical Field

[0001] The invention discloses a poultry carcass unloading and hanging machine, which belongs to the technical field of poultry slaughtering and processing equipment. Background Art

[0002] In poultry slaughtering and processing, the poultry carcasses after scalding and depilation need to be transferred from the slaughter hook to the evisceration hook for manual or automatic evisceration. Currently, there are two main methods of claw cutting and transfer: manual and machine: The first method is manual claw cutting and hanging. Currently, most poultry processing plants in my country use manual claw cutting and hanging. A production line with 12,000 chickens per hour requires more than 20 operators for manual claw cutting and hanging. The efficiency of claw cutting and hanging is low and the labor intensity is very high. This method can easily cause cross-contamination of poultry bodies and breed bacteria.

[0003] The second type is machinery and equipment: the utility model patent "automatic poultry carcass hanging machine" with publication number CN203327851U uses a three-axis linkage of a hanging mechanism, a hanging guide mechanism and a turning-out mechanism to realize the hanging of poultry carcasses from the slaughtering production line to the eviscerating production line; the utility model patent "four-axis claw cutting and hanging machine" with publication number CN213549381U uses a four-axis linkage of a hanging mechanism, a slaughtering guide mechanism, an eviscerating guide mechanism and a turning-out mechanism to realize the hanging of poultry carcasses from the slaughtering production line after claw cutting to the chest and back and hang them on the eviscerating production line.

[0004] The above technologies are all about automatically cutting the claws of the poultry carcass from the slaughter hook and transferring it to the eviscerating hook without unloading, and then automatically eviscerating. After eviscerating, if the poultry carcass is transferred from the eviscerating hook to the air-cooling hook or the weighing hook, the poultry carcass needs to be unloaded from the eviscerating hook first, and then transferred to the air-cooling hook or the weighing hook. Since it is difficult to realize automatic unloading and transfer in this process, manual unloading and transfer is currently adopted. A production line with 13,500 chickens / hour requires more than 10 operators for manual transfer, which has low transfer efficiency and high labor intensity. This method will also cause cross-contamination of poultry carcasses and breed bacteria. Summary of the invention

[0040] According to an optional embodiment of the present invention, Figures 16 and 17 As shown, the emergency poultry unloading assembly includes: A poultry unloading seat 28, which is fixed to the frame 1 below the lower turntable 9; A poultry unloading swing rod 29, one end of which is rotatably supported on the poultry unloading seat 28; The cylinder 30 has one end connected to the poultry unloading seat 28 and the other end connected to the poultry unloading swing rod 29, and is used to drive the poultry unloading swing rod 29 to rotate. Under normal circumstances, the piston rod end of the cylinder 30 drives the poultry unloading swing rod 29 to retract, allowing the poultry carcass to pass normally. When the poultry needs to be unloaded in an emergency, the piston rod end of the cylinder 30 drives the poultry unloading swing rod 29 to rotate and extend, so that the poultry carcass is unloaded from the poultry unloading hand 18.

[0041] According to an optional embodiment of the present invention, a poultry supporting wheel 31 is provided on the frame 1 at the lower right side of the poultry unloading cam 8 for supporting the poultry carcasses.

[0042] According to an optional embodiment of the present invention, a guide leg assembly 32 is provided on one side of the rotating hanging plate 27 to enable the poultry carcass to be hung on the air-cooling hook 25 .

[0043] According to an optional embodiment of the present invention, the upper ends of the unloading spindle 2 and the rotating spindle 23 are both provided with synchronous detectors 33, and the two synchronous detectors 33 control the synchronous operation of the unloading component and the rotating spindle.

[0044] It is important to note that: 1. If the unloading hand 18 rotates upward along the swing shaft 11 and interference occurs due to the incorrect position of the eviscerating hook 4, such as Fig.15 As shown, the steel ball 19 in the poultry unloading hand 18 will be forced to move out of the groove of the middle base plate 13, and the poultry unloading hand 18 will no longer move upward, protecting the poultry unloading hand 18 and the eviscerating hook 4 and other components from being damaged due to the incorrect position of the eviscerating hook 4.

[0045] 2. During the upward movement of the poultry unloading hand 18, the fixing and hanging unit 7 moves along the end surface track groove 802 through the bearing 703, driving the fixing and hanging rod 701 to slide outward along the dovetail groove 601, thereby ensuring that the gap between the eviscerating hook 4 and the poultry unloading hand 18 remains consistent during the poultry unloading process, thereby avoiding tearing of the poultry legs during the poultry unloading process.

[0046] The working steps of the present invention are as follows: Step 1: Hang the eviscerated poultry carcass on the evisceration hook 4.

[0047] Step 2: The eviscerating hook 4 hangs the poultry carcass along the unloading track 5 and enters the unloading assembly under the guidance of the unloading rotary wheel 3. First, the poultry supporting wheel 31 lifts the poultry carcass so that the poultry unloading hand 18 can be inserted into the poultry leg position. At the same time, the track wheel 16 of the poultry unloading rocker arm assembly moves downward along the circumferential track groove 801, so that the poultry unloading hand 18 rotates along the swing shaft 11 and extends upward into the poultry leg position to unload the poultry carcass and hang it on the poultry unloading hand 18. During the upward movement of the poultry unloading hand 18, the fixed hanging unit 7 moves along the end surface track groove 802 through the bearing 703, driving the fixed hanging rod 701 to slide outward along the dovetail groove 601 of the disc, which can ensure that the gap between the eviscerating hook 4 and the poultry unloading hand 18 remains consistent during the poultry unloading process, thereby avoiding tearing of the poultry legs during the poultry unloading process.

[0048] Step 3: The track wheel 16 of the poultry unloading rocker arm assembly moves upward along the circumferential track groove 801, so that the poultry unloading hand 18 moves downward along the swing shaft 11 to lay the poultry carcass flat.

[0049] Step 4: When the poultry unloading hand 18 reaches the intersection with the rotating hanging plate 27 , the legs of the poultry carcass are unloaded from the poultry unloading hand 18 through the leg guide assembly 32 and pushed into the rotating hanging plate 25 to be hung on the air cooling hook 25 .

[0050] Step 5: The poultry carcass hung on the air-cooling hook 25 is moved out from the rotating hanging assembly along the rotating hanging track 26 under the guidance of the rotating hanging rotating wheel 24, completing the whole process of unloading and rotating the poultry carcass.
