[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 The present invention provides a technical solution: an energy-saving continuous broiler slaughtering and depilating machine, comprising a box 1, and further comprising:

[0034] A notch 2 is provided on the side wall of the box body 1 and is used for the broiler to be transported;

[0035] Two groups of depilatory parts are symmetrically distributed about the notch groove 2. The depilatory parts include multiple groups of depilatory belts 8 installed inside the box body 1 and arranged vertically, and depilatory rollers 9 installed between the depilatory belts 8. The depilatory rollers 9 are also designed vertically. Depilatory rods are fixed on the outer walls of the depilatory belts 8 and the depilatory rollers 9. A depilatory area is formed between the depilatory belts 8 and the depilatory rollers 9 on both sides of the notch groove 2.

[0036] The driving assembly is used to drive the depilatory belt 8 to transmit in the vertical direction and drive the depilatory roller 9 to rotate in the axial direction, and the rotation directions of two adjacent depilatory rollers 9 are opposite.

[0037] Currently, when broiler chickens or other poultry are depilated in batches, they are usually hung upside down on iron hooks, slaughtered on a rolling knife during transportation, bled out, and then sent to a hot water washing device for preliminary scalding of the feathers. Finally, the feathers are removed through mechanical depilation.

[0038] However, although the hot water immersion method can effectively soften the chicken feathers, the time needs to be controlled and cannot be too long, otherwise it will cause certain thermal damage to the skin of the broiler, resulting in a decrease in the water content and weight of the broiler, affecting the quality of the broiler. However, if the hot water immersion time is shorter, the connection between the feathers and the chicken skin may still be relatively close. In this case, if the feathers are to be fully plucked, higher requirements are required for the subsequent mechanical plucking method to ensure the quality of the plucking. Therefore, in this case, the main focus is on further optimizing the subsequent mechanical plucking to improve the efficiency of broiler plucking.

[0039] Practical operation results show that in actual operation, some difficult-to-clean areas, such as the joints of chicken wings and chicken legs and skin folds, may still have a small amount of chicken feathers remaining, thus affecting the final quality of the broiler. Therefore, this case mainly optimizes this part to prevent chicken feathers from remaining between the above-mentioned areas. At the same time, it also avoids the subsequent secondary depilation process, making the depilation process more simple and efficient. The specific implementation method is as follows:

[0040] When the slaughtering and depilating machine is in use, the broilers that have undergone preliminary heat treatment will enter the depilating area formed by the depilating belts 8 and the depilating rollers 9 on both sides of the notch groove 2 on the box body 1 for depilation. Under the action of the driving component, the depilating belts 8 on both sides of the notch groove 2 will be driven vertically downward, such as Figure 4 In the direction indicated by the middle arrow, the feathers on the broiler are moved downward by using the feather removal rod on it, and at the same time, the feather removal roller 9 also rotates to move the feathers of the broiler horizontally, so as to achieve the effect of feather removal, and the feather removal belt 8 plays the main role of feather removal. In this way, the connection between the feathers and the chicken skin can be reduced by applying force in both vertical and horizontal directions, thereby achieving better feather removal effect and higher efficiency.

[0041] As the broiler moves, when it passes through the dehairing roller 9, since the rotation directions of the two adjacent dehairing rollers 9 are opposite, see Figure 7The middle arrow rotates in the direction shown. In the area shown in H, the horizontal forces applied to the broiler by the two adjacent depilatory rollers 9 are opposite, while in the area shown in L, the horizontal forces applied to the broiler by the two adjacent depilatory rollers 9 are relative. Therefore, when the broiler passes alternately through the L and H areas, it will switch back and forth between the two states of relative squeezing and pulling in opposite directions. On the one hand, this can continuously squeeze and pull the feathers on it, especially the roots of the feathers at the joints of the wings and legs and the wrinkles of the skin, which is conducive to weakening the connection between them and the cortex, so that the depilatory belt 8 can brush off the feathers at this position. On the other hand, in the process of continuous squeezing and pulling, the feathers at the above-mentioned positions will also be more easily entangled and bunched together, making it easier for the depilatory rod on the depilatory belt 8 to apply force, which is further conducive to the peeling of the feathers, improves the depilatory efficiency, and reduces the residual feathers.

[0042] In summary, the feather removal method using vertical and horizontal directions has a better feather removal effect, and there is no need for secondary feather removal. The degree of automation is high and the feather removal efficiency is improved.

[0043] In one of the more preferred embodiments, a method for installing the hair removal belt 8 is provided;

[0044] The inner wall of the box body 1 is rotatably mounted with a first rotating shaft 4 and a second rotating shaft 5, and the outer wall of the box body 1 is also mounted with a servo motor 6 for driving the second rotating shaft 5 to rotate. Transmission rollers 10 are fixed at intervals on the outer wall of the first rotating shaft 4, and roller assemblies are fixed at intervals on the outer wall of the second rotating shaft 5. The depilatory belt 8 is installed between the transmission roller 10 and the roller assembly.

[0045] For details, please refer to Figure 5 and Figure 6 The second rotating shaft 5 is driven to rotate by the servo motor 6, and the roller assembly and the transmission roller 10 can drive the depilatory belt 8 to achieve the above-mentioned depilatory purpose. Moreover, due to the design of the first rotating shaft 4 and the second rotating shaft 5, multiple depilatory belts 8 can be set synchronously without adding other separate driving sources, thereby reducing the cost between equipment and saving resources.

[0046] In one of the more preferred embodiments, a mounting method and a driving method of the depilatory roller 9 are provided;

[0047] The dehairing roller 9 is vertically rotatably installed on the inner wall of the box 1 between two adjacent dehairing belts 8 through an axle seat. The dehairing roller 9 and the outer wall of the second rotating shaft 5 are coaxially fixed with a bevel gear 12, and the two bevel gears 12 are meshed with each other.

[0048] For details, please refer to Figure 5 and Figure 6The hair removal roller 9 is installed between two adjacent hair removal belts 8, which is conducive to the broilers contacting with them alternately, and the meshing transmission between the bevel gears 12 is used. While the second shaft 5 drives the hair removal belt 8 to drive, it can also drive the hair removal roller 9 to rotate synchronously, and refer to Figure 5 By designing the position of the bevel gear 12, the rotation directions of the two adjacent depilatory rollers 9 can be opposite, while the rotation directions of the spaced depilatory rollers 9 are the same, thereby achieving the above-mentioned purpose of squeezing the broiler chicken in the center or pulling it to both sides.

[0049] In one of the more preferred embodiments, an implementation method is provided that can further improve the efficiency and effect of feather plucking;

[0050] A rotatable rotating shaft 16 is installed on the inner wall of the box body 1 close to the depilatory belt 8 through the shaft seat, and the rotating shaft 16 is located inside the depilatory belt 8. A tensioning cam 11 is fixed on the outer wall of the rotating shaft 16, and the tensioning cams 11 on the two adjacent rotating shafts 16 are designed in reverse.

[0051] See Figure 6 and Figure 8 From the above content, it can be seen that the transmission of the depilatory belt 8 is mainly used to drive the depilatory rod thereon to depilate the feathers. During the depilatory process, the rotating shaft 16 is driven to rotate by the external structure, thereby driving the tensioning cam 11 thereon to rotate, so that the raised part thereon will exert an outward pushing force on the depilatory belt 8, thereby further improving the depilatory rod on the depilatory belt 8 to move the broiler chickens, and further improving the depilatory effect;

[0052] In one of the more preferred embodiments, further optimization is made based on the above implementation mode;

[0053] The roller assembly includes an intermediate wheel 15 fixed on the outer wall of the second rotating shaft 5. The outer walls of the second rotating shaft 5 on both sides of the intermediate wheel 15 are slidably mounted with conical transmission wheels 13 through flat keys, and the conical surfaces of the two conical transmission wheels 13 are opposite to each other. The depilatory belt 8 is in friction contact with the two conical outer walls of the conical transmission wheels 13. The two conical transmission wheels 13 and the intermediate wheel 15 are connected with a tension spring 14 sleeved on the second rotating shaft 5. The intermediate wheel 15 and the rotating shaft 16 are connected through a transmission belt.

[0054] See Figure 8The depilatory belt 8 is driven between a drive roller and a drive roller 10 composed of two conical drive wheels 13. When the raised portion of the tensioning cam 11 contacts and abuts against the depilatory belt 8, the depilatory belt 8 will cause the two conical drive wheels 13 to slide back to each other under the action of the tensioning force, thereby reducing the contact between the depilatory belt 8 and the conical drive wheel 13, thereby increasing the transmission ratio between the conical drive wheel 13 and the depilatory belt 8. On the contrary, when the raised portion of the tensioning cam 11 is disengaged from the depilatory belt 8, the conical drive wheel 13 will be reset under the tension of the tension spring 14.

[0055] In this way, the transmission speed of the dehairing belt 8 has an intermittent acceleration process. This process, combined with the squeezing and pulling force exerted by the dehairing roller 9 on the broiler, can more effectively improve the dehairing efficiency of the feathers, while also ensuring the cleanliness of the dehairing and improving the quality of the broiler.

[0056] Moreover, it is worth mentioning that part of the feathers plucked by the depilatory rod will fall directly into the box body 1, while part of them will be entangled and embedded in the depilatory rod. When the feathers on the depilatory belt 8 are transported to the turning position at the lower end, as it suddenly accelerates, the wet feathers will be thrown downward under inertia and centrifugal force, thereby automatically cleaning the depilatory rod and avoiding excessive entanglement of the feathers on the depilatory belt 8 during the flow-type operation, thereby affecting the depilation efficiency.

[0057] In one of the more preferred embodiments, an installation position of the tensioning cam 11 is provided to further prevent damage to the broiler chickens due to excessive force;

[0058] The rotating shaft 16 located between the two relatively rotating depilatory rollers 9 is installed in a direction away from the notch groove 2, and the raised portion on the tensioning cam 11 can only contact the depilatory belt 8 on the side away from the notch groove 2. The rotating shaft 16 located between the two oppositely rotating depilatory rollers 9 is installed in a direction close to the notch groove 2, and the raised portion on the tensioning cam 11 can only contact the depilatory belt 8 on the side close to the notch groove 2.

[0059] As can be seen from the above content, in the L area, the broiler chickens will be subjected to a horizontal squeezing force toward the middle, so that the broiler chickens will have a tendency to gather together. Therefore, in the L area, the tensioning cam 11 of the depilatory belt 8 should not squeeze it outward when depilating, so as to avoid excessive pressure on the broiler chickens and affecting their meat quality. Therefore, the raised portion of the tensioning cam 11 in the depilatory belt 8 in the L area can only contact the depilatory belt 8 on the side away from the notch 2, so that the depilatory belt 8 can be changed in speed while ensuring that the broiler chickens are not affected.

[0060] Similarly, in the H region, the broiler chicken will be subjected to a horizontal pulling force to the sides, which will cause the broiler chicken to have a tendency to stretch and open. Therefore, in the H region, the tensioning cam 11 of the depilatory belt 8 can squeeze it outward when depilating, so as to prevent the depilatory rod on the depilatory belt 8 from reducing the pulling force on the broiler chicken and reducing the depilatory effect.

[0061] In summary, the above-mentioned problems can be overcome by designing the position of the tensioning cam 11, thereby improving the efficiency of plucking without affecting the quality of broilers.

[0062] In one of the more preferred embodiments, water spray pipes 7 are installed on the inner walls of both sides of the notch groove 2 near the top, and the outer wall of the water spray pipe 7 is installed with multiple nozzles arranged obliquely downward. The water spray pipe 7 is connected to the external water inlet pipe, and a drain pipe is also installed at the bottom of the box body 1.

[0063] See Figure 2 and Figure 6 By adding a water spray pipe 7, the depilatory belt 8 and the depilatory roller 9 can be fully rinsed to improve the cleaning effect, reduce bacterial growth, and also facilitate the shedding of feathers thereon;

[0064] In one of the more preferred embodiments, two chuck arc rods 3 are fixed to the inner bottom wall of the notch groove 2, and flared openings are formed on both sides of the two chuck arc rods 3, and a channel for limiting the chicken head is formed in the middle.

[0065] See Figure 1 and Figure 2 By adding two chuck arc rods 3, when broilers or other poultry are hung upside down and enter the notch slot 2, the chicken's head will enter under the two chuck arc rods 3, and the two will also limit it, so that only the chicken's neck can move inside, so that the broiler can always maintain a good condition during the movement and prepare for the above-mentioned depilation.

[0066] In one of the more preferred embodiments, the hair removal rod is made of rubber, and the lengths of the hair removal rods on two adjacent hair removal belts 8 are designed to be different.

[0067] In one of the more preferred embodiments, an observation window 17 is provided on the side wall of the box body 1 along the extending direction of the notch groove 2 , and a transparent plate is embedded in the observation window 17 .

[0068] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

[0069] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
