Description

Technical Field

[0001] This invention belongs to the technical field of spray immunization equipment for chicks, and more specifically, it relates to an electric anesthesia machine for poultry slaughter. Background Technology

[0002] Chicken, rich in nutrients, has become an important meat source in modern people's daily lives. With the widespread application of modern chicken processing technology in my country, slaughterhouses generally use electric stunning machines to stun live chickens before slaughter; common electric stunning machines include... Figure 1 As shown, the device includes an electric stunning box with an opening at the top and a conveyor mechanism b for transporting poultry upside down. The electric stunning box has an inlet and an outlet at its front and rear ends, respectively, both connected to the top opening. Inside the box is a water trough a filled with electrically charged water. When the upside-down poultry are transported through the water trough by their heads, they are stunned by the electric shock. However, due to differences in poultry size, the water level in the trough is generally high, close to full, to ensure sufficient immersion. When the poultry struggle from the electric shock or when they come out of the trough, a significant amount of water spills onto the ground, overflows, or splashes onto the inlet end of the trough, wasting water and causing the water level in the trough to drop. Too rapid anesthesia increases water supply costs. If sufficient water is not replenished in time, it will affect the overall anesthesia effect. In order to avoid excessive stress on poultry, the anesthesia machine is generally placed in a dark environment. Water spilled from the tank onto the ground is not conducive to the personal safety of the staff and requires regular manual cleaning, which increases labor costs. Furthermore, the splashing of electrified water onto the feed end of the tank will cause poultry that have passed through but not fully entered the tank to retract their heads prematurely, which is not conducive to successful anesthesia. Insufficient electric shocks require more manual supplementary killing, affecting the anesthesia effect. Overall, there are problems of poor anesthesia effect, high anesthesia cost, and low safety. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an electric anesthesia machine for poultry slaughter, which has the advantages of good electric anesthesia effect, low electric anesthesia cost and high safety.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An electric stunning machine for poultry slaughter includes a conveying device, an electric stunning box with internal electrode connectors, and a water inlet tank connected to one side of the electric stunning box. The conveying device is connected to a leg support frame for fixing the suspended poultry legs. A guide plate for supporting and adjusting the poultry's head is connected to the outer side of the feed end of the electric stunning box, and an insulating baffle for preventing water splashing outside the electric stunning box is connected to the inner side of the feed end. The guide plate and the insulating baffle are integrally formed and both are inclined upwards towards the inside of the electric stunning box. The discharge end of the electric dominoes box is connected to a return discharge plate that is inclined upwards away from the electric dominoes box. Side baffles are connected to both sides of the return discharge plate. A set of return holes is opened on the inner side wall of the electric dominoes box near the return discharge plate. A circulation pipe is connected between the rear end of the water inlet tank and the return holes. A water supply pipe is connected between the front end of the water inlet tank and the front end of the electric dominoes box. The bottom of the water inlet tank is provided with a slope that is inclined upwards from front to back. A timed water supply device is installed above the front end of the water inlet tank.

[0005] Further configuration: The timed water replenishment device includes an inlet pipe and a water wheel. One end of the inlet pipe is mounted above one side of the water wheel. The water wheel is rotatably connected to both sides of the front end inside the water inlet tank. The other end of the inlet pipe is connected to a water pump and a water supply tank located outside the water inlet tank. The outlet of the water supply tank is connected to a first solenoid valve and a timer. Both the electric shock box and the bottom of the water inlet tank are provided with drain outlets, and the drain outlets are connected to a second solenoid valve.

[0006] Further feature: The waterwheel is provided with an arc-shaped baffle on the side near the water inlet pipe.

[0007] Further setting: The distance between the top of the insulating baffle and the bottom of the leg fixing frame is in the range of 20-30cm.

[0008] Further features: The feeding end of the electric jellie box is provided with a feeding port; the two sides of the insulating baffle are fixedly connected to the two inner sides of the electric jellie box near the feeding port; the bottom of the insulating baffle is fixedly connected to the bottom of the feeding port; and a waterproof layer is connected between the two sides of the insulating baffle and the two inner sides of the electric jellie box, and between the insulating baffle and the bottom of the feeding port.

[0009] Further configuration: A front fixing plate is fixedly connected to one side of the upper end face of the guide plate; a front adjusting plate for adjusting the poultry's head is slidably connected to the other side of the upper end face of the guide plate along its width; a first spring is connected between the side of the front adjusting plate away from the front fixing plate and the side of the guide plate; a front adjusting channel that gradually narrows towards the electric stun box is formed between the front adjusting plate and the front fixing plate; a rear fixing plate is fixedly connected to one side of the upper end face of the insulating baffle; a rear adjusting plate for adjusting the sides of the poultry's body is slidably connected to the other side of the upper end face of the insulating baffle along its width; a second spring is connected between the side of the rear adjusting plate away from the rear fixing plate and the side of the insulating baffle; a rear adjusting channel that gradually narrows towards the electric stun box is formed between the rear adjusting plate and the rear fixing plate.

[0010] Further configuration: Both the rear adjustment plate and the rear fixed plate are rotatably connected to several sets of first massage rollers.

[0011] Further configuration: The section of the conveying device located above the feed end of the electric jellies is a feeding conveying section. The feeding conveying section is inclined downward towards the electric jellies and is located directly above the front end of the guide plate and the insulating baffle.

[0012] Further configuration: A belt conveyor is mounted below the guide plate, with its conveying direction parallel to the guide plate's inclination direction; multiple fixed seats are evenly connected along the conveyor belt of the belt conveyor; an infrared sensor for detecting whether poultry is passing by is installed on one side of the guide plate; two arc-shaped clamps for fixing the poultry's head are hinged to both sides of each fixed seat; a protective pad for the poultry's head is installed in the middle of the fixed seat; a clearance groove is opened along the middle of the guide plate for the arc-shaped clamps and the conveying end face of the belt conveyor to pass through; the insulating baffle is close to... One side of the clearance groove is provided with a support pad for supporting the poultry's head. Both sides of the upper end face of the guide plate are connected to intermediate adjustment plates for adjusting the opening angle of the arc-shaped clamp. The two intermediate adjustment plates are respectively located on both sides of the clearance groove. The outer side of the arc-shaped clamp is in contact with the intermediate adjustment plate. A third spring is connected between the outer side of the arc-shaped clamp and the fixed seat. A front limiting channel that gradually narrows towards the electric sedation box is formed between the front ends of the two intermediate adjustment plates. A rear limiting channel that gradually widens towards the electric sedation box is formed between the rear ends of the two intermediate adjustment plates.

[0013] Further configuration: The upper end face of the insulating baffle is rotatably connected to the two sides of a second massage roller for massaging the backs of poultry.

[0014] In summary, this invention, through a leg support frame, a conveying device, a guide plate, and an insulating baffle, adjusts the height of the poultry's head and neck, ensuring the poultry remains calm during transport before electric shock. Simultaneously, the insulating baffle prevents water from overflowing or splashing out of the tank or onto the poultry awaiting electroshock, thus achieving initial water conservation and ensuring the effectiveness of the electroshock. When the poultry's head reaches the top of the insulating baffle, the conveying device continues to move the poultry horizontally towards the electroshock chamber. The poultry's head, having left the top of the insulating baffle, suddenly loses support and, under the influence of gravity, quickly falls into the water within the electroshock chamber, denying the poultry time to retract its neck and preventing neck contraction. The neck section further enhances the overall electro-anesthesia effect; the return discharge plate redirects the water waves generated when a row of stunned poultry is conveyed towards the discharge end of the electro-anesthesia box, preventing water from flowing outside the box and thus conserving water resources while ensuring the effectiveness of the electro-anesthesia; the return water is diverted into the inlet tank through return holes, ramps, and circulation pipes, preventing the return water from colliding with the new wave of water and causing water to flow out from the side baffle, further conserving water resources and ensuring the effectiveness of the electro-anesthesia; the timed water replenishment device and inlet pipe allow for regular water changes or replenishment of the electro-anesthesia box; the overall structure is simple and has the advantages of good electro-anesthesia effect, low cost, and high safety.

Detailed Implementation

[0017] To explain the technical content, objectives, and effects of this invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. It should be noted that the terms "above" and "below" used in the following description refer to the attached drawings. Figure 2 and Figure 7 The direction in the middle, the words "bottom" and "top" refer to the attached Figure 2 and Figure 7 The direction towards the geometric center of a specific component.

[0018] Please refer to Figures 2 to 8 As shown, an electric stunner for poultry slaughter includes a conveying device 1, an electric stunner box 2 with internal electrode connectors, and a water inlet tank 3 connected to one side of the electric stunner box 2. The conveying device 1 is connected to a leg fixing frame 4 for fixing the suspended poultry legs. A guide plate 5 for supporting and adjusting the poultry head is connected to the outer side of the feed end of the electric stunner box 2, and an insulating baffle 6 for preventing water from splashing out of the electric stunner box 2 is connected to the inner side of the feed end of the electric stunner box 2. The guide plate 5 and the insulating baffle 6 are integrally formed and are both inclined upwards towards the inside of the electric stunner box 2. The electric domino box 2 has a discharge end connected to a return discharge plate 7 that is inclined upwards away from the electric domino box 2. Side baffles 8 are connected to both sides of the return discharge plate 7. A set of return holes are opened on the inner side wall of the electric domino box 2 near the return discharge plate 7. A circulation pipe 10 is connected between the rear end of the water inlet tank 3 and the return holes. A water supply pipe is connected between the front end of the water inlet tank 3 and the front end of the electric domino box 2. The bottom of the water inlet tank 3 is provided with a ramp 12 that is inclined upwards from front to back. A timed water supply device is installed above the front end of the water inlet tank 3.

[0019] As described above, when poultry needs to be electro-stimulated, the poultry's legs are hung on the leg support frame 4. The conveyor device 1 then gradually raises the head and neck of the inverted poultry, first through the guide plate 5 and then through the insulating baffle 6. When the poultry reaches the insulating baffle 6, it is already inside the electro-stimulation box 2. The insulating baffle 6 prevents water from overflowing or splashing out of the water tank or onto the poultry to be electro-stimulated, thus achieving initial water conservation and ensuring the electro-stimulation effect. When the poultry's head reaches the top of the insulating baffle 6, the conveyor device 1 continues to move the poultry horizontally into the electro-stimulation box 2. The head of the poultry leaving the top of the insulating baffle 6 suddenly loses support and, under the influence of gravity, quickly falls into the water inside the electro-stimulation box 2, preventing the poultry from retracting its neck. The guide plate 5 and insulating baffle 6 are used to gradually raise the head and neck of the poultry. The support plates 5 and 6 provide support for the poultry, keeping them calm during transport before the electric shock. The support is then suddenly removed, preventing the poultry from having time to retract their necks, thus further enhancing the overall anesthesia effect. The return discharge plate 7 redirects the water waves generated during the transport of a row of stunned poultry towards the discharge end of the anesthesia box 2, preventing water from flowing outside the box and further conserving water resources while ensuring the anesthesia effect. The return water is diverted to the inlet tank 3 via the return hole, ramp 12, and circulation pipe 10, preventing it from colliding with the new wave of water and causing water to flow out from the side baffle 8, further conserving water resources and ensuring the anesthesia effect. The timed water replenishment device and pipe ensure regular water changes or replenishment in the anesthesia box 2.

[0020] Furthermore, the timed water replenishment device includes an inlet pipe 11 and a water wheel 14. One end of the inlet pipe 11 is mounted above one side of the water wheel 14. The water wheel 14 is rotatably connected to both sides of the front end inside the water inlet tank 3. The other end of the inlet pipe 11 is connected to a water pump and a water supply tank 16 located outside the water inlet tank 3. The outlet of the water supply tank 16 is connected to a first solenoid valve 15 and a timer 17. The bottom of both the electric shock box 2 and the water inlet tank 3 is provided with a drain outlet 21, and the drain outlet 21 is connected to a second solenoid valve.

[0021] As described above, when the water in the water supply tank needs to be replaced at the preset time, the external controller first controls the second solenoid valve to open, and the wastewater in the electric shock box 2 and the water inlet tank 3 is discharged to the outside through the drain outlet 21. After the water in the electric shock box 2 and the water inlet tank 3 is discharged, the external controller then controls the second solenoid valve to close and the first solenoid valve 15 to open. The water in the water supply tank 16 is pumped to the water inlet pipe 11 by the water pump, and flows into the water wheel 14 through one end of the water inlet pipe 11. The gravity of the water drives the water wheel 14 to rotate downwards to pour the water into the water inlet tank 3, which plays the role of replenishing water at regular intervals. By setting the water wheel 14, the falling speed of the water is reduced, and water splashes outside the water inlet tank 3 are further prevented, which plays the role of further saving water resources and ensuring the electric shock effect.

[0022] Furthermore, an arc-shaped baffle 18 is provided on the side of the water turbine 14 near the water inlet pipe 11.

[0023] As can be seen from the above description, the arc-shaped baffle 18 is used to prevent water from the water wheel 14 from splashing into one end of the water inlet pipe 11.

[0024] Furthermore, the distance between the top of the insulating baffle 6 and the bottom of the leg fixing bracket 4 is in the range of 20-30cm.

[0025] As can be seen from the above description, the distance between the top of the insulating baffle 6 and the bottom of the leg fixing frame 4 is 20-30cm to prevent poultry from tilting too much, which could cause leg damage or excessive reaction.

[0026] Furthermore, the feeding end of the electric jellies 2 is provided with a feeding port 23. The two sides of the insulating baffle 6 are fixedly connected to the two inner sides of the electric jellies 2 near the feeding port 23. The bottom of the insulating baffle 6 is fixedly connected to the bottom of the feeding port 23. A waterproof layer is connected between the two sides of the insulating baffle 6 and the two inner sides of the electric jellies 2, and between the insulating baffle 6 and the bottom of the feeding port 23.

[0027] As can be seen from the above description, by setting waterproof layers at the connection points between the two sides of the insulating baffle 6 and the two inner sides of the electric taming box 2, and at the connection points between the insulating baffle 6 and the bottom of the feed inlet 23, it is possible to prevent electrified water from flowing from the connection points between the two sides of the insulating baffle 6 and the two inner sides of the electric taming box 2, and at the connection points between the insulating baffle 6 and the bottom of the feed inlet 23, onto the insulating baffle 6 or the guide plate 5 or outside the electric taming box 2, thereby preventing poultry on the insulating baffle 6 or the guide plate 5 from prematurely developing stress reactions, causing safety hazards, or leading to water waste.

[0028] Furthermore, a front fixing plate 25 is fixedly connected to one side of the upper end face of the guide plate 5; a front adjusting plate 26 for adjusting the head of the poultry is slidably connected to the other side of the upper end face of the guide plate 5 along its width; a first spring 27 is connected between the side of the front adjusting plate 26 away from the front fixing plate 25 and one side of the guide plate 5; a front adjusting channel 28 that gradually narrows towards the electric stun box 2 is formed between the front adjusting plate 26 and the front fixing plate 25; a rear fixing plate 29 is fixedly connected to one side of the upper end face of the insulating baffle 6; a rear adjusting plate 30 for adjusting the two sides of the poultry's body is slidably connected to the other side of the upper end face of the insulating baffle 6 along its width; a second spring 31 is connected between the side of the rear adjusting plate 30 away from the rear fixing plate 29 and one side of the insulating baffle 6; a rear adjusting channel 32 that gradually narrows towards the electric stun box 2 is formed between the rear adjusting plate 30 and the rear fixing plate 29.

[0029] As described above, the front adjustment plate 26, the first spring 27, the front fixing plate 25, and the front adjustment channel 28 serve to gradually limit and adjust the head of the poultry, preventing frequent shaking and guiding and calming the poultry to avoid excessive shaking that could cause them to hit the sides of the electric stun box 2 and produce an overreaction. Similarly, the rear adjustment plate 30, the second spring 31, the rear fixing plate 29, and the rear adjustment channel 32 serve to guide and calm the poultry while gradually limiting and adjusting the sides of their bodies. The first spring 27 and the second spring 31 are designed to accommodate poultry with different head circumferences and body sizes.

[0030] Furthermore, both the rear adjustment plate 30 and the rear fixed plate 29 are rotatably connected to several sets of first massage rollers 20.

[0031] As can be seen from the above description, during the movement of poultry, the first massage roller 20 is rotated, and the rotation of the first massage roller 20 is used to massage both sides of the poultry's body, keeping the poultry in a calm and comfortable state.

[0032] Furthermore, the section of the conveying device 1 above the feed end of the electric jumbo box 2 is the feeding conveying section 13. The feeding conveying section 13 is inclined downward towards the electric jumbo box 2 and is located directly above the front end of the guide plate 5 and the insulating baffle 6.

[0033] Furthermore, a belt conveyor 34 is mounted below the guide plate 5, with its conveying direction parallel to the inclination direction of the guide plate 5. Multiple fixed seats are evenly connected along the conveying direction of the belt conveyor 34. An infrared sensor 19 for detecting whether poultry is passing by is installed on one side of the guide plate 5. Two arc-shaped clamps 35 for fixing the heads of poultry are hinged to both sides of each fixed seat. A protective pad 36 for placing the poultry's head is installed in the middle of the fixed seat. A clearance groove 37 is opened along the middle of the guide plate 5, allowing the arc-shaped clamps 35 and the conveying end face of the belt conveyor 34 to pass through. An insulating baffle 6 is located near the clearance groove. One side of 37 is provided with a support pad 33 for supporting the poultry's head. Both sides of the upper end face of the guide plate 5 are connected with intermediate adjustment plates 38 for adjusting the opening angle of the arc-shaped clamp 35. The two intermediate adjustment plates 38 are located on both sides of the clearance groove 37. The outer side of the arc-shaped clamp 35 contacts the intermediate adjustment plate 38. A third spring 39 is connected between the outer side of the arc-shaped clamp 35 and the fixed seat. A front limiting channel 40 is formed between the front ends of the two intermediate adjustment plates 38, which is gradually narrowed towards the electric sedation box 2. A rear limiting channel 41 is formed between the rear ends of the two intermediate adjustment plates 38, which is gradually widened towards the electric sedation box 2.

[0034] As described above, when the head of the inverted poultry is at the arc-shaped clamp 35 of the conveyor belt 34, the infrared sensor 19 detects the presence of poultry and sends a signal to the external controller. The external controller then starts the conveyor belt 34. The poultry's head first contacts the protective pad 36, which prevents the poultry's head from directly colliding with the fixed seat, thus protecting the poultry's head and preventing stress reactions caused by impact pain. Then, the conveyor belt 34 transports the fixed plate and the arc-shaped clamp 35 together with the poultry's head towards the electric shock box 2. The arc-shaped clamp 35 first passes through the intermediate adjustment in the front limit channel 40. As the front end of the section plate 38 is pushed, the two arc-shaped clamps 35 gradually close until the poultry's head is limited between the arc-shaped clamps 35. This action simulates the action of a human hand closing and fixing the poultry's head, reducing the amplitude of the poultry's head shaking. After the poultry adapts for a period of time, the poultry will keep its head still for a period of time. That is, during the process of the poultry passing through the middle section of the two intermediate adjustment plates 38, the arc-shaped clamps 35 gradually open under the elastic force of the third spring 39 through the rear limiting channel 41, which can achieve the effect of calming the poultry in advance. When entering the insulating baffle 6 from the clearance channel 37, the supporting soft pad 33 is used to provide transition support for the poultry's head.

[0035] Furthermore, the upper end face of the insulating baffle 6 is rotatably connected to the second massage rollers 42 for massaging the backs of poultry.

[0036] As can be seen from the above description, in order to avoid stress reactions in poultry when they are on the insulating baffle 6 or when they are transitioning from the clearance channel 37, the second massage roller 24 is rotated during the movement of the poultry. This allows the second massage roller 42 to massage the two sides of the poultry's back over a large area, keeping the poultry in a calm and comfortable state and further soothing the poultry.

The feeding conveying section 13 is inclined downward towards the electric jumbo box 2. The feeding conveying section 13 is located directly above the front end of the guide plate 5 and the insulating baffle 6.

[0043] Example 2 differs from Example 1 in that, as Figures 6 to 8As shown, the poultry being conveyed by the conveyor device 1 is in a back-to-forward position, i.e., towards the electric taming box. When it moves to the insulating baffle, the back of the poultry contacts the insulating baffle. A belt conveyor 34 is mounted below the rear guide plate 5, with its conveying direction parallel to the inclination direction of the guide plate 5. Multiple fixed seats are evenly connected along the conveying direction of the belt conveyor 34. An infrared sensor 19 for detecting whether poultry has passed is installed on one side of the guide plate 5.

A third spring 39 is connected between the outer side of the arc-shaped clamp 35 and the fixed seat. A front limiting channel 40 is formed between the front ends of the two intermediate adjustment plates 38, which gradually narrows towards the electric sedation box 2. A rear limiting channel 41 is formed between the rear ends of the two intermediate adjustment plates 38, which gradually widens towards the electric sedation box 2. The upper surface of the insulating baffle 6 is rotatably connected to the second massage rollers 42 for massaging the back of the poultry. The friction between the poultry head and the guide plate 5 is reduced by using the arc-shaped clamp 35 and the belt conveyor 34.

[0044] In summary, compared with existing technologies, this invention has the advantages of better electro-anesthesia effect, lower cost, and higher safety. The leg support frame 4, conveying device 1, guide plate 5, and insulating baffle 6 are used to adjust the height of the poultry's head and neck, ensuring the poultry is in a calm state during transport before electric shock. Simultaneously, the insulating baffle 6 prevents water from overflowing or splashing out of the tank or onto the poultry awaiting electro-anesthesia, thus achieving initial water conservation and ensuring the effectiveness of the electro-anesthesia. When the poultry's head moves to the top of the insulating baffle 6, the conveying device 1 continues to move the poultry horizontally towards the electro-anesthesia box 2. The poultry's head, having left the top of the insulating baffle 6, suddenly loses support, and... Under the influence of gravity, the water quickly falls into the electric stun box 2, giving the poultry no time to retract their necks, thus preventing them from doing so and further improving the overall stun effect. The return discharge plate 7 is used to return the waves of water generated when a row of stunned poultry is conveyed towards the discharge end of the electric stun box 2, preventing the water from flowing outside the electric stun box 2, thus further saving water resources and ensuring the stun effect. The returned water is diverted to the inlet tank 3 through the return hole, the ramp 12, and the circulation pipe 10, which further saves water resources and ensures the stun effect. The timed water replenishment device and the inlet pipe 11 are used to regularly change or replenish the water in the electric stun box 2.
