Description

Technical Field

[0001] This application relates to the field of food processing technology, specifically to a device for removing hair from pig hooves. Background Technology

[0002] Food processing refers to the processing of grains, feeds, vegetable oils and sugars, slaughtering and meats, aquatic products, vegetables, fruits and nuts, as well as tubers, dehydrated vegetables and canned vegetables, using agricultural, forestry, animal husbandry and fishery products as raw materials. It is a type of agricultural product processing industry in a broad sense.

[0003] An existing patent (publication number: CN210492385U) discloses a pig hoof hair removal device, including a base plate and support legs fixedly connected to the four corners of the lower surface of the base plate. A cover is fixedly connected to both sides of the upper surface of the base plate. The cover and the base plate form a cavity structure with openings on the front and back. The cavity structure is equipped with a conveying mechanism for conveying pig hooves from the back opening to the front opening and a flame nozzle for scorching the pig hair. The conveying mechanism continuously conveys the pig hooves into the cover with the flame nozzle. The pig hair on the hooves is scorched and gelatinized by the flames emitted from the flame nozzle, achieving rapid hair removal. This not only simplifies the pig hoof hair removal process but also reduces manual labor, lowers the labor intensity of workers, and greatly improves the efficiency of pig hoof hair removal.

[0004] The aforementioned document describes a method to remove hair from pig trotters using flames, which reduces work efficiency. However, the burnt hair adheres to the outer surface of the trotters and forms black grime. The document lacks the ability to remove this grime, requiring subsequent cleaning. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a pig trotter hair removal device, which has advantages such as improved practicality and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a pig hoof hair removal device, comprising a housing, a support on the left side of the housing, a driven shaft mounted on the inner wall of the support, a metal conveyor belt drivingly connecting the driven shaft to an external drive shaft, two hair removal units mounted on the inner wall of the support, multiple chains fixedly connected to the outer surface of the housing, the multiple chains being connected to external equipment, and the middle ends of the multiple chains being drooping, a rotating frame rotatably connected to the inner wall of the housing, multiple circumferentially distributed cleaning tanks fixedly opened on the outer surface of the rotating frame, drain pipes mounted on the inner walls of the multiple cleaning tanks, nozzles fixedly connected to the outer surfaces of the multiple drain pipes, rotating components rotatably connected to the inner walls of the multiple cleaning tanks, and two sets of swing rods fixedly connected to the outer surfaces of the multiple rotating components.

[0007] The above scheme allows for the conveying of pig hooves by installing a chain and a metal conveyor belt. Due to the resistance between the chain and the pig hooves, and the conveying action of the metal conveyor belt, the pig hooves can be rotated on the metal conveyor belt. Combined with the indirect flame spraying from the dehairing unit, the hair on the surface of the pig hooves can be removed evenly.

[0008] Rotating rods are fixedly connected to the outer surfaces of multiple rotating components, and gears are fixedly connected to the outer surfaces of the rotating rods. A gear ring is fixedly connected to the front of the outer shell, and multiple gears mesh with the gear ring. A drive rod is fixedly connected to the front of the rotating frame, and the drive rod is fixedly connected to the output end of an external motor. The engagement of the gears and gear rings enables the rotating rods to rotate during the rotation of the rotating frame. This rotation causes the swing rods to agitate the pig hooves in the cleaning tank, allowing them to be evenly washed by the water jet, thereby improving the hair removal efficiency of the pig hooves.

[0009] Each of the multiple cleaning tanks has two slag discharge troughs on its inner wall. The inner wall of the rotating frame is rotatably connected to a filter element. The slag discharge troughs facilitate the discharge of impurities removed during the cleaning of pig trotters, preventing impurities from remaining in the cleaning tank. The impurities washed out can pass through the filter element and be filtered, facilitating the recycling of water resources.

[0010] A rotating ring is fixedly connected to the rear end of each of the multiple drain pipes. A water supply frame is provided at the rear of the housing. The rotating ring is rotatably connected to the water supply frame through a sealed bearing. A water inlet pipe is fixedly connected to the back of the water supply frame. The other end of the water inlet pipe is fixedly connected to the output end of an external water pump. The cooperation between the rotating ring and the water supply frame facilitates the delivery of water. This ensures that water enters the drain pipes stably during the oscillation of the multiple drain pipes. The sealed bearing also seals the connection between the rotating ring and the water supply frame, preventing water leakage.

[0011] The outer surface of the shell is provided with a feeding trough and a discharging trough. The feeding trough and the discharging trough facilitate the entry of pig hooves into the cleaning tank, and the pig hooves can be discharged through the discharging trough by rotating the rotating frame.

[0012] A counterweight is fixedly connected to the outer surface of the filter element. Installing the counterweight increases the weight of the filter element, keeping it stable during rotation and preventing it from flipping over. This allows the filter element to filter impurities stably.

[0013] A water storage tank is fixedly connected to the outer surface of the shell. The installation of the water storage tank facilitates the storage of water resources after use. At the same time, the discharged pig trotters can be soaked in the water storage tank, and the water resources in the water storage tank can be extracted and reused.

[0014] The inner bottom wall of the feeding trough is inclined, which makes it easier for pig hooves to roll into the cleaning trough and for the outer surface of the pig hooves to be washed by water jets.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This pig hoof hair removal device uses a chain and metal conveyor belt to transport pig hooves. Due to the resistance between the chain and the pig hoof, and the conveying action of the metal conveyor belt, the pig hoof is turned over on the belt. Combined with the indirect flame spraying from the hair removal unit, the hair on the surface of the pig hoof can be removed evenly. A rotating frame is installed to transport the pig hoof, and high-pressure water jets are sprayed onto the outer surface of the pig hoof to remove impurities. Furthermore, the swing arm allows the pig hoof to tumble in the cleaning tank, ensuring that the water jets clean the surface of the pig hoof more evenly, thus improving the overall practicality.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a pig hoof hair removal device includes a housing 1, a support 2 on the left side of the housing 1, a driven shaft 3 installed on the inner wall of the support 2, a metal conveyor belt 4 drivingly connecting the driven shaft 3 to an external drive shaft, two hair removal units 5 installed on the inner wall of the support 2, the two hair removal units 5 being able to indirectly spray flames to remove pig hair from the pig hoof, multiple chains 6 fixedly connected to the outer surface of the housing 1, the multiple chains 6 being connected to external equipment, and the middle ends of the multiple chains 6 being drooping, a rotating frame 7 rotatably connected to the inner wall of the housing 1, multiple circumferentially distributed cleaning tanks 8 fixedly opened on the outer surface of the rotating frame 7, drain pipes 9 installed on the inner walls of the multiple cleaning tanks 8, and nozzles 10 fixedly connected to the outer surfaces of the multiple drain pipes 9. The inner walls of multiple cleaning tanks 8 are rotatably connected to rotating parts 11, and the outer surfaces of multiple rotating parts 11 are fixedly connected to two sets of swing rods 12. By installing chains and metal conveyor belts 4, pig hooves can be conveyed. Due to the resistance between the chain and the pig hooves, and through the conveying of the metal conveyor belt 4, the pig hooves can be turned over on the metal conveyor belt 4. With the help of the dehairing unit 5, the flame can be sprayed indirectly to remove the hair on the surface of the pig hooves evenly. By installing rotating frames 7, the pig hooves can be conveyed, and by spraying high-pressure water jets on the outer surface of the pig hooves, impurities on the surface of the pig hooves can be removed. With the help of the swing rods 12, the pig hooves can be turned over in the cleaning tanks 8, so that the water jets can clean the surface of the pig hooves more evenly, thereby improving the overall practicality.

[0026] Please see Figure 1 , Figure 3 and Figure 4Multiple rotating parts 11 have rotating rods 13 fixedly connected to their outer surfaces, and gears 14 fixedly connected to the outer surfaces of their rotating rods 13. A gear ring 15 is fixedly connected to the front of the outer shell 1, and multiple gears 14 mesh with the gear ring 15. A drive rod 16 is fixedly connected to the front of the rotating frame 7, and the drive rod 16 is fixedly connected to the output end of an external motor. The engagement of the gears 14 and the gear ring 15 enables the rotating rods 13 to rotate during the rotation of the rotating frame 7, causing the rotating rods 13 to drive the swing rods 12 to turn over the pig hooves in the cleaning tank 8, so that they can be evenly washed by the water column, thereby improving the hair removal efficiency of the pig hooves. Two slag discharge troughs 17 are opened on the inner walls of the multiple cleaning tanks 8, and a filter element 18 is rotatably connected to the inner wall of the rotating frame 7. The slag discharge troughs 17 facilitate the removal of hair from the pig hooves. Impurities removed during the cleaning of pig trotters are drained to prevent them from remaining in the rinsing tank. The flushed impurities pass through the filter element 18 and are filtered, facilitating the recycling of water resources. A rotating ring 19 is fixedly connected to the rear end of multiple drain pipes 9. A water supply frame 20 is provided at the rear of the outer casing 1. The rotating ring 19 is rotatably connected to the water supply frame 20 through a sealed bearing. A water inlet pipe 21 is fixedly connected to the back of the water supply frame 20, and the other end of the water inlet pipe 21 is fixedly connected to the output end of an external water pump. The cooperation between the rotating ring 19 and the water supply frame 20 facilitates the delivery of water, ensuring a stable flow of water into the drain pipes 9 during their oscillation. The sealed bearing also seals the area between the rotating ring 19 and the water supply frame 20, preventing water leakage.

[0027] Please see Figure 1 , Figure 4 and Figure 5 The outer surface of the outer shell 1 is provided with a feeding trough 22 and a discharging trough 23. The feeding trough 22 and the discharging trough 23 facilitate the entry of pig hooves into the cleaning tank 8, and the pig hooves can be discharged through the discharging trough 23 by the rotation of the rotating frame 7. The outer surface of the filter element 18 is fixedly connected with a counterweight 24. The installation of the counterweight 24 can increase the self-weight of the filter element 18, so that the filter element 18 can maintain a stable state during the rotation of the rotating frame 7, and prevent the filter element 18 from overturning, so that the filter element 18 can stably filter impurities. The outer surface of the outer shell 1 is fixedly connected with a water storage tank 25. The installation of the water storage tank 25 can facilitate the storage of water resources after use. At the same time, the discharged pig hooves can be soaked in the water storage tank 25, and the water resources in the water storage tank 25 can be extracted and reused. The inner bottom wall of the feeding trough 22 is inclined, which facilitates the rolling of pig hooves into the cleaning tank 8, and facilitates the washing of the outer surface of the pig hooves by the water jet.

[0028] This embodiment of a pig hoof hair removal device uses a chain and a metal conveyor belt 4 to transport pig hooves. Due to the resistance between the chain and the pig hoof, and the transport by the metal conveyor belt 4, the pig hoof can be turned over on the metal conveyor belt 4. In conjunction with the hair removal unit 5, which indirectly sprays flames, the hair on the surface of the pig hoof can be removed evenly. The rotating frame 7 can be used to transport the pig hoof, and high-pressure water jets can be sprayed onto the outer surface of the pig hoof to remove impurities. Furthermore, the swing rod 12 can be used to turn the pig hoof over in the cleaning tank 8, so that the water jets can clean the surface of the pig hoof more evenly, thereby improving the overall practicality.

[0029] The working principle of the above embodiment is as follows: When cleaning the hair on the surface of pig hooves, the pig hooves are first placed on the metal conveyor belt 4. Then, the cooperation of the external drive shaft and driven shaft 3 drives the metal conveyor belt 4 to transport the pig hooves. When the pig hooves come into contact with the chain 6, the resistance of the chain 6 and the conveying force of the metal conveyor belt 4 can make the pig hooves turn on the metal conveyor belt 4. Then, the dehairing unit 5 can indirectly spray flames onto the pig hooves, which can evenly remove the hair on the surface of the pig hooves. When the amount of pig hooves transported increases, the contact between pig hooves decreases, the resistance between the pig hooves and the chain 6 decreases, and the metal conveyor belt 4 can transport the pig hooves into the feed trough 22. At this time, the external drive rod 16 drives the rotating frame 7 to rotate, so that the rotating frame 7 can allow the pig hooves to enter the cleaning tank 8 during the rotation. At this time, the external water pump draws water from the water storage tank 25 and delivers it to the water supply frame 20. Through the water supply frame 20, it enters multiple drain pipes 9 and is sprayed out from multiple nozzles 10. The outer surface of the pig's trotters is cleaned. During the rotation of the rotating frame 7, the gear 14 and the gear ring 15 work together to drive multiple rotating rods 13 to rotate. During the rotation of the rotating rods 13, multiple swing rods 12 drive the rotating parts 11 to turn the pig's trotters in the cleaning tank 8, so that the water column can clean the outer surface of the pig's trotters evenly. During the cleaning process, the impurities on the surface of the pig's trotters can enter the rotating frame 7 through the slag discharge trough 17 and be filtered by the filter element 18. By installing the counterweight 24, the weight of the filter element 18 can be increased, so that the filter element 18 can be kept stable during the rotation of the rotating frame 7, preventing the filter element 18 from turning over and ensuring that the filter element 18 can stably filter impurities. After the pig's trotters are cleaned, the pig's trotters and water can be discharged into the water storage tank 25 through the discharge trough, thus completing the hair removal and cleaning of the pig's trotters and improving the overall practicality.
