Description

Technical Field

[0001] This application relates to the field of livestock dehairing equipment technology, and more specifically, to a livestock dehairing machine with an adjustable scraper. Background Technology

[0002] Livestock dehairing machines (also known as dehairing machines) are key pieces of equipment in the slaughtering and processing stage, mainly used to remove hair from the surface of pigs to improve meat hygiene standards and processing efficiency. Taking the most widely used spiral pig dehairing machine as an example, its working principle is based on a combination of mechanical friction and spiral propulsion. The internal design of the equipment features a first scraper (actually quite blunt, and may also be called a scraper blade) arranged in a spiral around a first rotating shaft. When the pig is fed into the dehairing chamber, as the first rotating shaft rotates, the first scraper generates strong friction with the pig's surface, effectively removing the hair. At the same time, the propulsive action of the spirally arranged first scraper ensures that the pig moves evenly within the chamber, achieving full-body dehairing and avoiding any omissions.

[0003] Spiral-type pig dehairing machines are mainly used in large slaughterhouses, meat processing plants, and central kitchens. As a core piece of equipment in the dehairing process, it directly affects the efficiency and quality of subsequent processing and cutting. Its high efficiency and continuous operation enable large-scale slaughtering operations to proceed smoothly, meeting market demand for pork products. However, in existing livestock dehairing equipment, the first scraper is completely fixed relative to the first rotating shaft, making it impossible to adjust the distance the first scraper extends into the dehairing chamber. Since livestock vary in size, sometimes the first scraper, which enters the dehairing chamber laterally, cannot even reach smaller animals, thus affecting the dehairing effect. Conversely, for larger animals, a fixed-extension first scraper may cause excessive compression, increasing the risk of skin and meat damage. Summary of the Invention

[0004] In view of this, this application provides a livestock dehairing machine with an adjustable scraper to solve the technical problems of poor dehairing effect and easy damage to the dehairing object in the prior art.

[0005] This application provides a livestock dehairing machine with an adjustable scraper, wherein the livestock dehairing machine with an adjustable scraper includes: The brushing chamber has a brushing cavity inside, which extends bidirectionally through the brushing chamber along its length. The brushing cavity has an inlet at one end along its length and an outlet at the other end. Multiple entry channels are formed on the wall of the brushing chamber at intervals along its length. A lateral depilatory device located on one side of the depilatory chamber in the width direction includes a first rotating shaft and a plurality of connecting arms arranged at axial intervals along the first rotating shaft, and a first scraper disposed at the end of the connecting arms. The axis of the first rotating shaft is arranged along the length direction of the depilatory chamber. When the first rotating shaft rotates, the first scrapers on the plurality of connecting arms can enter the depilatory chamber one by one through their respective entry channels. The connecting arms are movably arranged relative to the first rotating shaft, which can change the vertical distance between the first scraper disposed on the connecting arm and the first rotating shaft.

[0006] Further, the connecting arm includes a first arm and a second arm. The first arm is connected to the first rotating shaft, and the second arm is hinged to the first arm via a hinge shaft. Each second arm has a corresponding first scraper hinged to its end away from the first arm. The first arm and the second arm cooperate with a first elastic element. When the first rotating shaft is not rotating, the first elastic element keeps the second arm in a bent position. In the bent position, the angle between the second arm and the first arm is a first angle, which is less than 180°. When the first rotating shaft rotates, the centrifugal force of the first scraper can drive the second arm to move against the elastic force of the first elastic element and be in an extended position. In the extended position, the angle between the second arm and the first arm is a second angle, which is greater than the first angle and less than or equal to 180°.

[0007] Furthermore, the first elastic element is a torsion spring disposed on the hinge shaft.

[0008] Furthermore, a first ear plate is provided on the side of the first arm, a second ear plate is provided on the side of the second arm, and the first elastic element is a first spring connected between the first ear plate and the second ear plate.

[0009] Furthermore, the lateral deburring device also includes a plurality of sliding support arms arranged axially at intervals along the first rotating shaft and a second scraper slidably disposed at the end of the sliding support arm. When the second scraper slides along the corresponding sliding support arm, it can change the vertical distance between the second scraper and the first rotating shaft. When the first rotating shaft rotates at a speed less than a first predetermined value, the second scrapers on the plurality of sliding support arms can enter the deburring chamber one by one through their respective entry channels. When the first rotating shaft rotates at a speed greater than or equal to the first predetermined value, the second scrapers on the plurality of sliding support arms never enter the deburring chamber.

[0010] Furthermore, the lateral deburring device includes a second elastic element and a retraction trigger. One end of the second elastic element is connected to the second scraper, and the other end is connected to the sliding support arm. The second elastic element generates a force that causes the second scraper to move away from the sliding support arm. The second scraper is connected to a triggered element that cooperates with the retraction trigger. When the first rotating shaft rotates at a speed less than a first predetermined value, the retraction trigger and the triggered element do not interact with each other. The elastic force of the second elastic element and the centrifugal force of the second scraper enable the second scrapers on the plurality of sliding support arms to enter the deburring chamber one by one through their respective entry channels. When the first rotating shaft rotates at a speed greater than or equal to the first predetermined value, the retraction trigger acts on the trigger, causing the second scraper to retract toward the first rotating shaft, so that the second scrapers on the plurality of sliding support arms never enter the deburring chamber.

[0011] Furthermore, the adjustable scraper livestock dehairing machine includes multiple trigger guide arms disposed on a first rotating shaft. These trigger guide arms are correspondingly disposed on one side of each sliding support arm. The retraction trigger is a first magnetic element slidably disposed on each of the trigger guide arms, and the triggered element is a second magnetic element. When the first magnetic element slides along the corresponding trigger guide arm, it can change the vertical distance between the first magnetic element and the first rotating shaft. A third elastic element connects the first magnetic element and the trigger guide arm. When the first rotating shaft rotates at a speed less than a first predetermined value, the distance between the first magnetic element and the second magnetic element is greater than the predetermined distance under the elastic force of the third elastic element, so that the first magnetic element and the second magnetic element do not magnetically attract each other. When the first rotating shaft rotates at a speed greater than or equal to the first predetermined value, the first magnetic element overcomes the elastic force of the third elastic element under the action of centrifugal force and slides away from the first rotating shaft, so that the first magnetic element magnetically attracts the second magnetic element in the direction toward the first rotating shaft.

[0012] Furthermore, the adjustable scraper livestock dehairing machine also includes a bottom dehairing device located below the dehairing chamber. The bottom dehairing device includes a second rotating shaft and a plurality of fixed arms arranged at intervals along the axial direction of the second rotating shaft, and a third scraper disposed at the end of the fixed arms. The axis of the second rotating shaft is arranged along the length direction of the dehairing chamber. When the second rotating shaft rotates, the third scrapers on the plurality of fixed arms can enter the dehairing chamber one by one through the respective entry channels.

[0013] Furthermore, the first scrapers on the plurality of connecting arms are arranged in a spiral trajectory along the axial direction of the first rotating shaft, the second scrapers on the plurality of sliding support arms are arranged in a spiral trajectory along the axial direction of the first rotating shaft, and the third scrapers on the plurality of fixed arms are arranged in a spiral trajectory along the axial direction of the second rotating shaft.

[0014] Furthermore, the livestock dehairing machine with adjustable scraper includes a controller, a vision sensor, and a motor. The controller is connected to the vision sensor and the motor respectively. The vision sensor is located at the inlet of the dehairing chamber. The output shaft of the motor is coaxially connected to the first rotating shaft. A first pulley is provided on the first rotating shaft, and a second pulley is provided on the second rotating shaft. The first pulley and the second pulley are connected by a transmission belt.

[0015] The beneficial effects of the livestock dehairing machine with adjustable scraper provided in this application are as follows: Compared to existing technologies, in the livestock dehairing machine with adjustable scrapers provided by this invention, when the first rotating shaft rotates, the first scrapers on the plurality of connecting arms can enter the dehairing chamber one by one through their respective entry channels. The connecting arms are movably arranged relative to the first rotating shaft, allowing the vertical distance between the first scrapers on the connecting arms and the first rotating shaft to be changed. Therefore, the vertical distance of the first scraper relative to the first rotating shaft is adjustable, meaning the distance the first scraper extends into the dehairing chamber is adjustable. This allows, on the one hand, when the livestock (e.g., pigs) passing through the dehairing chamber is large, the distance the first scraper extends into the dehairing chamber from one side can be adjusted to a smaller distance, preventing the first scraper from obstructing the dehairing chamber. If the hair cavity extends too far, it can cause excessive compression and injury to the livestock being haired. On the other hand, when the livestock to be haired (such as pigs) passing through the hair cavity is small (such as piglets), the distance from which the first scraper extends into the hair cavity from one side can be adjusted to a greater distance. This avoids the situation where the first scraper extends too short into the hair cavity and fails to reach the livestock being haired. Overall, this livestock hairing machine with an adjustable scraper can selectively adjust the distance the first scraper extends into the hair cavity according to the size of the livestock passing through it, thereby adapting to the hairing operation of livestock of different sizes. This greatly improves the efficiency, safety, and adaptability of livestock hairing operations to livestock of different sizes. Attached Figure Description

[0023] See Figures 1 to 7 This application provides a livestock dehairing machine with an adjustable scraper, wherein the livestock dehairing machine with an adjustable scraper includes: The brushing chamber 100 has a brushing cavity inside. The brushing cavity runs bidirectionally through the brushing chamber 100 along its length. The brushing cavity has an inlet 101 at one end along its length and an outlet 102 at the other end. Multiple entry channels 103 are formed on the wall of the brushing chamber 100 at intervals along its length. The brushing chamber 100 may specifically include a top plate 105 and multiple arched frames 104 arranged at intervals below the top plate 105 along its length. An entry channel 103 is formed between adjacent arched frames 104. The lateral deburring device located on one side of the deburring chamber 100 in the width direction includes a first rotating shaft 1, a plurality of connecting arms arranged at intervals along the axial direction of the first rotating shaft 1, and a first scraper 2 disposed at the end of the connecting arm. The first scraper 2 is preferably a metal part with a certain elasticity and is detachably connected to the end of the connecting arm by bolts or screws or other components. The axis of the first rotating shaft 1 is arranged along the length direction of the deburring chamber 100. When the first rotating shaft 1 rotates, the first scrapers 2 on the plurality of connecting arms can enter the deburring chamber one by one through each entry channel 103. The connecting arms are movably arranged relative to the first rotating shaft 1, which can change the vertical distance between the first scraper 2 disposed on the connecting arm and the first rotating shaft 1.

[0024] In the livestock dehairing machine with adjustable scrapers provided by this invention, when the first rotating shaft 1 rotates, the first scrapers 2 on the multiple connecting arms can enter the dehairing chamber one by one through the respective entry channels 103. The connecting arms are movably arranged relative to the first rotating shaft 1, allowing the vertical distance between the first scrapers 2 on the connecting arms and the first rotating shaft 1 to be changed. Therefore, the vertical distance of the first scraper 2 relative to the first rotating shaft 1 is adjustable, meaning the distance the first scraper 2 extends into the dehairing chamber is adjustable. This allows, on the one hand, that when the livestock (e.g., pigs) passing through the dehairing chamber is large, the distance the first scraper 2 extends from one side of the dehairing chamber 100 into the dehairing chamber can be adjusted to a smaller distance, preventing the first scraper 2 from extending too far into the dehairing chamber. However, excessive compression of the animals to be dehaired can cause injury. On the other hand, when the animals to be dehaired (such as pigs) passing through the dehairing chamber are small (such as piglets), the distance from which the first scraper 2 extends into the dehairing chamber from one side of the dehairing chamber 100 can be adjusted to a larger distance. This avoids the phenomenon that the first scraper 2 extends too short into the dehairing chamber and cannot reach the animals to be dehaired. Overall, this livestock dehairing machine with adjustable scrapers can selectively adjust the distance of the first scraper 2 extending into the dehairing chamber according to the size of the animals to be dehaired passing through the dehairing chamber, thereby adapting to the dehairing operation of animals of different sizes. This greatly improves the efficiency, safety, and adaptability of livestock dehairing operations for animals of different sizes.

[0025] According to a preferred embodiment of this application, a plurality of connecting arms are also arranged at intervals along the circumferential direction of the first rotating shaft 1. For example, four connecting arms are arranged at equal 90° intervals along the circumferential direction of the first rotating shaft 1. Of course, the end of each connecting arm is connected to a first scraper 2.

[0026] According to one embodiment of this application, the connecting arm includes a first arm 3 and a second arm 4. The first arm 3 is connected to a first rotating shaft 1, and the second arm 4 is hinged to the first arm 3 via a hinge shaft 7. A corresponding first scraper 2 is hinged to the end of each second arm 4 away from the first arm 3. The first arm 3 and the second arm 4 are engaged by a first elastic element. When the first rotating shaft 1 is not rotating, the first elastic element keeps the second arm 4 in a bent position. In the bent position, the angle between the second arm 4 and the first arm 3 is a first angle, which is less than 180°. When the first rotating shaft 1 rotates, the centrifugal force of the first scraper 2 can drive the second arm 4 to overcome the elastic force of the first elastic element and move to an extended position. In the extended position, the second... The angle between arm 4 and the first arm 3 is the second angle, which is greater than the first angle and less than or equal to 180°. In this embodiment, the faster the rotation speed of the first shaft 1, the greater the centrifugal force on the first scraper 2, and the slower the rotation speed of the first shaft 1, the smaller the centrifugal force on the first scraper 2. Therefore, the vertical distance between the first scraper 2 and the first shaft 1 can be adjusted by controlling the rotation speed of the first shaft 1, so as to adjust the distance the first scraper 2 extends into the deburring chamber. When the distance the first scraper 2 extends into the deburring chamber needs to be shorter, the rotation speed of the first shaft 1 can be slowed down. When the distance the first scraper 2 extends into the deburring chamber needs to be longer, the rotation speed of the first shaft 1 can be increased.

[0027] According to a specific embodiment of this application, a first mounting sleeve 5 is provided on the first arm 3, and a second mounting sleeve 6 is provided on the second arm 4. Both the first mounting sleeve 5 and the second mounting sleeve 6 are fitted onto the hinge shaft 7 and are axially limited relative to the hinge shaft 7. For example, end flanges (not shown) are provided at both ends of the hinge shaft 7 to limit the first mounting sleeve 5 and the second mounting sleeve 6 between the end flanges at both ends of the hinge shaft 7.

[0028] According to one embodiment of this application, the first elastic element is a torsion spring disposed on the hinge shaft 7.

[0029] According to another embodiment of this application, a first ear plate 8 is provided on the side of the first arm 3, a second ear plate 9 is provided on the side of the second arm 4, and the first elastic member is a first spring 10 connected between the first ear plate 8 and the second ear plate 9.

[0030] According to one embodiment of this application, the lateral deburring device further includes a plurality of sliding support arms 11 arranged axially at intervals along the first rotating shaft 1 and a second scraper 12 slidably disposed on the sliding support arms 11. When the second scraper 12 slides along the corresponding sliding support arm 11, it can change the vertical distance between the second scraper 12 and the first rotating shaft 1. When the first rotating shaft 1 rotates at a speed less than a first predetermined value, the second scrapers 12 on the plurality of sliding support arms 11 can enter the deburring chamber one by one through each entry channel 103. When the first rotating shaft 1 rotates at a speed greater than or equal to the first predetermined value, the second scrapers 12 on the plurality of sliding support arms 11 never enter the deburring chamber.

[0031] According to one embodiment of this application, the lateral deburring device includes a second elastic element (e.g., a second spring 13) and a retraction trigger. One end of the second elastic element is connected to a second scraper 12, and the other end is connected to a sliding support arm 11. The second elastic element generates a force that causes the second scraper 12 to move away from the sliding support arm 11. The second scraper 12 is connected to a triggered element that cooperates with the retraction trigger. When the first rotating shaft 1 rotates at a speed less than a first predetermined value, the retraction trigger and the triggered element do not interact with each other. The elastic force of the second elastic element and the centrifugal force of the second scraper 12 cause the second scraper on the multiple sliding support arms 11 to move away from the sliding support arm 11. The blades 12 can enter the deburring chamber one by one through the respective entry channels 103. When the first rotating shaft 1 rotates at a speed greater than or equal to a first predetermined value, the retraction trigger acts on the trigger, causing the second blades 12 to retract toward the first rotating shaft 1, so that the second blades 12 on the multiple sliding support arms 11 never enter the deburring chamber. As mentioned above, the method of adjusting the distance the first blade 2 extends into the deburring chamber is as follows: when a shorter distance is needed for the first blade 2 to extend into the deburring chamber, the rotation speed of the first rotating shaft 1 can be slowed down; when a longer distance is needed for the first blade 2 to extend into the deburring chamber, the rotation speed of the first rotating shaft 1 can be increased. The rotation speed increases, so when dehairing larger livestock, the rotation speed of the first shaft 1 decreases. This reduces the frequency at which the first scraper 2 contacts the larger livestock. To ensure that the dehairing frequency for larger livestock does not decrease or even increases, this embodiment includes a second scraper 12. When the rotation speed of the first shaft 1 decreases, for example, when the first shaft 1 rotates at a speed less than a first predetermined value, the retraction trigger and the triggered element do not interact. The elastic force of the second elastic element and the centrifugal force of the second scraper 12 allow the second scrapers 12 on the multiple sliding support arms 11 to pass through each entry channel 1 in a one-to-one correspondence. 03 When entering the dehairing chamber, it ensures that when the rotation speed of the first rotating shaft 1 slows down, the second scraper 12 acts as a supplementary scraper to dehair larger livestock. When dehairing smaller livestock, the rotation speed of the first rotating shaft 1 increases. When the first rotating shaft 1 rotates at a speed greater than or equal to the first predetermined value, the retraction trigger is activated, causing the second scraper 12 to retract toward the first rotating shaft 1. This ensures that the second scrapers 12 on the multiple sliding support arms 11 never enter the dehairing chamber. In other words, when dehairing smaller livestock, the second scraper 12 can be prevented from performing dehairing work.

[0032] According to a specific embodiment of this application, the lateral deburring device includes a first sliding sleeve 14 slidably fitted on a sliding support arm 11. A stop block 15 is provided at the end of the sliding support arm 11 to prevent the first sliding sleeve 14 from falling off. The second scraper 12 is preferably a metal part with a certain elasticity and is detachably connected to the outside of the first sliding sleeve 14 by bolts or screws or other components. Specifically, a third ear plate 27 is provided on the first sliding sleeve 14, a fourth ear plate 28 is provided on the sliding support arm 11, one end of the second spring 13 is connected to the third ear plate 27, and the other end of the second spring 13 is connected to the fourth ear plate 28.

[0033] According to a specific embodiment of this application, the adjustable scraper livestock dehairing machine includes a plurality of trigger guide arms 16 disposed on a first rotating shaft 1. The plurality of trigger guide arms 16 are correspondingly disposed on one side of each sliding support arm 11. The retraction trigger is a first magnetic element 17 (e.g., a magnet) slidably disposed on each trigger guide arm 16, and the triggered element is a second magnetic element 18 (e.g., a magnet). The second magnetic element 18 can be connected to the outside of a first sliding sleeve 14. When the first magnetic element 17 slides along the corresponding trigger guide arm 16, it can change the vertical distance between the first magnetic element 17 and the first rotating shaft 1. A first magnetic element 17 is connected to the trigger guide arm 16 via a second magnetic element 18. When the first rotating shaft 1 rotates at a speed less than a first predetermined value, the distance between the first magnetic element 17 and the second magnetic element 18 is greater than a predetermined distance under the action of the elastic force of the third elastic element, so that the first magnetic element 17 and the second magnetic element 18 do not magnetically attract each other. When the first rotating shaft 1 rotates at a speed greater than or equal to the first predetermined value, the faster the rotation speed of the first rotating shaft 1, the greater the centrifugal force can be generated on the first magnetic element 17. Under the action of the centrifugal force, the first magnetic element 17 overcomes the elastic force of the third elastic element and slides away from the first rotating shaft 1, so that the first magnetic element 17 magnetically attracts the second magnetic element 18 in the direction toward the first rotating shaft 1.

[0034] According to a specific embodiment of this application, the lateral deburring device includes a second sliding sleeve 29 slidably sleeved on each trigger guide arm 16, a first magnetic element 17 installed on the corresponding second sliding sleeve 29, a fifth ear plate 30 provided on the second sliding sleeve 29, a sixth ear plate 31 provided on the trigger guide arm 16, one end of a third spring 19 connected to the fifth ear plate 30, and the other end of the third spring 19 connected to the sixth ear plate 31.

[0035] According to one embodiment of this application, the adjustable scraper livestock dehairing machine further includes a bottom dehairing device located below the dehairing chamber 100. The bottom dehairing device includes a second rotating shaft 20 and a plurality of fixed arms 21 arranged at intervals along the axial direction of the second rotating shaft 20, and a third scraper 22 disposed at the end of the fixed arms 21. The third scraper 22 is preferably a metal part with a certain elasticity and is detachably connected to the end of the fixed arm 21 by bolts or screws or other components. The axis of the second rotating shaft 20 is arranged along the length direction of the dehairing chamber 100. When the second rotating shaft 20 rotates, the third scrapers 22 on the plurality of fixed arms 21 can enter the dehairing chamber one by one through the respective entry channels 103. Since livestock of all sizes, whether large or small, are pressed against the bottom surface of the dehairing chamber, the distance that the third scraper 22 extends into the bottom surface of the dehairing chamber is a fixed value, but the distance that extends into the bottom surface of the dehairing chamber should not be too large.

[0036] According to a preferred embodiment of this application, a plurality of fixed arms 21 are also arranged at intervals along the circumferential direction of the second rotating shaft 20. For example, four fixed arms 21 are arranged at equal 90° intervals along the circumferential direction of the second rotating shaft 20. Of course, a third scraper 22 is connected to the end of each fixed arm 21.

[0037] According to one embodiment of this application, the first scrapers 2 on multiple connecting arms are arranged in a spiral trajectory along the axial direction of the first rotating shaft 1, the second scrapers 12 on multiple sliding support arms 11 are arranged in a spiral trajectory along the axial direction of the first rotating shaft 1, and the third scrapers 22 on multiple fixed arms 21 are arranged in a spiral trajectory along the axial direction of the second rotating shaft 20. This allows the first scrapers 2, second scrapers 12, and third scrapers 22 to generate a pushing force along the length direction of the hair removal chamber 100 on the livestock inside the hair removal chamber when they rotate around their corresponding rotations. Specifically, this can generate a pushing force from the inlet 101 toward the outlet 102, thereby pushing the livestock inside the hair removal chamber out of the outlet 102 of the hair removal chamber while the hair removal operation is being performed.

[0038] In other embodiments, the first scraper 2, the second scraper 12, and the third scraper 22 may not be arranged in a spiral trajectory. In this case, it is only necessary to set the bottom surface of the deburring chamber to have an inclination angle, so that the bottom surface of the deburring chamber slopes downward from the inlet 101 of the deburring chamber 100 toward the outlet 102.

[0039] According to one embodiment of this application, a livestock dehairing machine with an adjustable scraper includes a controller (not shown), a vision sensor (not shown), and a motor 23. The controller is signal-connected to both the vision sensor and the motor 23. The vision sensor is located at the inlet 101 of the dehairing chamber. The output shaft of the motor 23 is coaxially connected to a first rotating shaft 1. A first pulley 24 is provided on the first rotating shaft 1, and a second pulley 25 is provided on a second rotating shaft 20. The first pulley 24 and the second pulley 25 are connected by a transmission belt 26. After the vision sensor acquires the body shape information of the livestock entering the dehairing chamber from the inlet 101, it transmits the body shape information to the controller. The controller controls the rotation speed of the motor 23, thereby controlling the rotation speed of the first rotating shaft 1 and the second rotating shaft 20 to adaptively adjust the distance the first scraper 2 extends into the dehairing chamber and adaptively control whether the second scraper 12 enters or does not enter the dehairing chamber. This allows the livestock dehairing machine with an adjustable scraper provided by this application to adaptively adapt to the dehairing operations of livestock of different sizes.

A lateral depilatory device located on one side of the depilatory chamber in the width direction includes a first rotating shaft and a plurality of connecting arms arranged at axial intervals along the first rotating shaft, and a first scraper disposed at the end of the connecting arms. The axis of the first rotating shaft is arranged along the length direction of the depilatory chamber. When the first rotating shaft rotates, the first scrapers on the plurality of connecting arms can enter the depilatory chamber one by one through their respective entry channels. The connecting arms are movably arranged relative to the first rotating shaft, which can change the vertical distance between the first scraper disposed on the connecting arm and the first rotating shaft.

2. The livestock dehairing machine with an adjustable scraper according to claim 1, characterized in that, The connecting arm includes a first arm and a second arm. The first arm is connected to the first rotating shaft, and the second arm is hinged to the first arm via a hinge shaft. Each second arm has a corresponding first scraper hinged to its end away from the first arm. The first arm and the second arm cooperate with a first elastic element. When the first rotating shaft is not rotating, the first elastic element keeps the second arm in a bent position. In the bent position, the angle between the second arm and the first arm is a first angle, which is less than 180°. When the first rotating shaft rotates, the centrifugal force of the first scraper can drive the second arm to move against the elastic force of the first elastic element and be in an extended position. In the extended position, the angle between the second arm and the first arm is a second angle, which is greater than the first angle and less than or equal to 180°.

3. The livestock dehairing machine with an adjustable scraper according to claim 2, characterized in that, The first elastic element is a torsion spring disposed on the hinge shaft.

4. The livestock dehairing machine with an adjustable scraper according to claim 2, characterized in that, The first arm has a first ear plate on its side, the second arm has a second ear plate on its side, and the first elastic element is a first spring connected between the first ear plate and the second ear plate.

5. The livestock dehairing machine with an adjustable scraper according to claim 2, characterized in that, The lateral deburring device further includes a plurality of sliding support arms arranged axially at intervals along the first rotating shaft and a second scraper slidably disposed at the end of the sliding support arm. When the second scraper slides along the corresponding sliding support arm, it can change the vertical distance between the second scraper and the first rotating shaft. When the first rotating shaft rotates at a speed less than a first predetermined value, the second scrapers on the plurality of sliding support arms can enter the deburring chamber one by one through their respective entry channels. When the first rotating shaft rotates at a speed greater than or equal to the first predetermined value, the second scrapers on the plurality of sliding support arms never enter the deburring chamber.

6. The livestock dehairing machine with an adjustable scraper according to claim 5, characterized in that, The lateral deburring device includes a second elastic element and a retraction trigger. One end of the second elastic element is connected to the second scraper, and the other end is connected to the sliding support arm. The second elastic element generates a force that causes the second scraper to move away from the sliding support arm. The second scraper is connected to a triggered element that cooperates with the retraction trigger. When the first rotating shaft rotates at a speed less than a first predetermined value, the retraction trigger and the triggered element do not interact with each other. The elastic force of the second elastic element and the centrifugal force of the second scraper enable the second scrapers on the plurality of sliding support arms to enter the deburring chamber one by one through their respective entry channels. When the first rotating shaft rotates at a speed greater than or equal to the first predetermined value, the retraction trigger acts on the trigger, causing the second scraper to retract toward the first rotating shaft, so that the second scrapers on the plurality of sliding support arms never enter the deburring chamber.

7. The livestock dehairing machine with an adjustable scraper according to claim 6, characterized in that, The adjustable scraper livestock dehairing machine includes multiple trigger guide arms mounted on a first rotating shaft. These trigger guide arms are correspondingly mounted on one side of each sliding support arm. The retraction trigger is a first magnetic element slidably mounted on each trigger guide arm, and the triggered element is a second magnetic element. When the first magnetic element slides along its corresponding trigger guide arm, it can change the vertical distance between itself and the first rotating shaft. A third elastic element connects the first magnetic element and the trigger guide arm. When the first rotating shaft rotates at a speed less than a first predetermined value, the distance between the first magnetic element and the second magnetic element is greater than the predetermined distance under the elastic force of the third elastic element, so that the first magnetic element and the second magnetic element do not magnetically attract each other. When the first rotating shaft rotates at a speed greater than or equal to the first predetermined value, the first magnetic element overcomes the elastic force of the third elastic element under centrifugal force and slides away from the first rotating shaft, so that the first magnetic element magnetically attracts the second magnetic element in the direction toward the first rotating shaft.
