Description

Technical Field

[0001] This utility model belongs to the field of pig by-product processing technology, and specifically relates to a pig by-product processing equipment. Background Technology

[0002] Pig by-products refer to the edible or economically valuable parts of a pig after slaughter, excluding the main pork portion. Common pig by-products mainly include head-related by-products, offal by-products, limb by-products, as well as other by-products such as pig skin and pig bones. These pig by-products are widely used in food processing, catering, and pharmaceutical industries.

[0003] Pig trotters are a common limb-type pig by-product. Fresh pig trotters usually need to be split in half during cold chain transportation. This is because split pig trotters can be stacked or placed more tightly, saving space in packaging boxes, cold storage, and transport vehicles compared to whole pig trotters, thus reducing logistics costs. Moreover, during freezing or refrigeration, cold air can penetrate the split pig trotters more evenly and quickly, shortening freezing time, improving the utilization rate of cold storage space, and ensuring the quality of frozen products.

[0004] Existing high-speed bone saws used to directly cut fresh pig trotters have several drawbacks: First, pig trotters are rich in tough connective tissue and hard hoof bones and cartilage. During high-speed sawing, the pulling and friction of the saw blade causes significant tearing, compression deformation, and damage to the soft tissue, resulting in an extremely uneven cut surface with many burrs, affecting the final product's appearance and taste. Second, fresh pig trotter bones have a moderate hardness and brittleness. Sawing them produces a large number of sharp bone fragments and fine bone dust; these hard foreign objects severely contaminate the meat and are almost impossible to completely remove afterwards, posing a food safety hazard and seriously affecting the eating experience. Third, the high-speed friction of the saw blade generates high heat locally on the cut surface, causing varying degrees of burning and charring of the skin, meat, and connective tissue at the edges, affecting color, smell, and even producing off-flavors.

[0005] Therefore, we provide a pig by-product processing device for halving fresh pig trotters. Utility Model Content

[0006] The purpose of this utility model is to overcome at least one of the aforementioned problems in the existing technology and to provide a pig by-product processing device, the specific technical solution of which is as follows:

[0007] This utility model provides a pig by-product processing equipment, including a rectangular frame structure operating table, on the top surface of which a splitting mechanism for splitting pig hooves in half is fixed along its short axis.

[0008] The splitting mechanism includes a platform fixed on an operating frame. A long, narrow cutting hole is opened through the top surface of the platform along its long axis. A cutter is inserted into the cutting hole with gaps. One end of the cutter is fixed to a long rod-shaped handle, and the other end is pivotally connected to a support plate that is vertically and symmetrically fixed on both sides of the corresponding end of the cutting hole. Semi-cylindrical straightening plates are vertically and symmetrically fixed on both sides of the cutting hole. The two straightening plates are used together to longitudinally support the pig's hoof.

[0009] On the operating platform located on both sides of the splitting mechanism, there are detachable material troughs. One material trough is used to pile up unsplit pig trotters, and the other material trough is used to pile up split pig trotters.

[0010] As a preferred embodiment of this utility model, the top surface of the operating platform is symmetrically fixed with support rods at horizontal intervals along its short axis; the four corners of the platform are symmetrically fixed with mounting blocks, and the mounting blocks are fixed to the ends of the corresponding support rods by fastening bolts.

[0011] As a preferred technical solution of this utility model, a support block is vertically fixed to the top surface of the end of the platform facing the handle, and the support block and the cutting hole are on the same straight line; an arc-shaped groove is opened inward on the top surface of the support block, and a rubber pad is fixedly attached to the inner wall of the groove.

[0012] As a preferred technical solution of this utility model, a limit component is provided on one side of the end of the cut hole that is on the same side as the support plate;

[0013] The limiting component includes a support plate two that is vertically fixed to the top surface of the platform, and a limiting screw is horizontally and vertically screwed through the support plate two; when the handle of the cutter rests flat on the rubber pad of the support block, the limiting screw can be screwed into and engaged with the limiting groove opened on the cutter.

[0014] As a preferred embodiment of this utility model, both the first support plate and the second support plate are L-shaped structures.

[0015] As a preferred technical solution of this utility model, the material trough is a square trough structure, and an annular flange is integrally provided on the circumferential edge of its top opening; the material trough is detachably suspended on the top surface of the corresponding end of the operating table by a matching support assembly;

[0016] The support assembly includes a square frame that engages longitudinally with the material trough, and the bottom surface of the annular flange of the material trough is in contact with the top surface of the square frame; a pair of inverted U-shaped hooks are respectively fixed vertically and symmetrically on the two end faces of the square frame, and the hooks engage longitudinally with the long side of the top surface of the operating table; a straight rod-shaped handle is vertically fixed to the outer end face of the hook.

[0017] The beneficial effects of this utility model are:

[0018] 1. This invention significantly improves the cross-sectional quality of pig trotters after splitting, enhancing product appearance and taste. The core of the splitting mechanism in this equipment lies in the coordinated design of the cutting blade and the cutting hole. Compared to high-speed bone saws, this splitting method applies a vertical and uniform force, avoiding the pulling and friction of the pig trotter's connective tissue by the high-speed rotating saw blade. Because the splitting force acts directly on the hard bone and cartilage of the pig trotter, the soft tissue is not torn or deformed, resulting in a smoother and flatter cross-section, reducing burrs and damage.

[0019] 2. This invention effectively reduces contamination from bone fragments and foreign objects, ensuring food safety and a pleasant eating experience. The design of the cutting blade and the gap between the cutting holes form a guiding channel, ensuring a linear and controllable splitting process. Simultaneously, the semi-cylindrical shape of the centering plate stably restricts the position of the pig's trotters, preventing them from shifting during cutting. The splitting process produces larger bone fragments and fewer fine bone debris. The larger bone fragments are easier to remove in subsequent processing. This significantly reduces the risk of contamination of meat products by hard foreign objects, eliminating potential food safety hazards.

[0020] 3. This invention avoids heat damage and maintains the stable color and aroma of pig's trotters. The pivotal connection and manual operation mechanism of the cutting blade in this device make the splitting process controllable and slower. Simultaneously, the design of the cutting holes guides the blade's linear movement, reducing the frictional contact area. Manual operation avoids the mechanical frictional heat generated by high-speed sawing, preventing a sudden increase in localized temperature on the cut surface. The blade's contact time with the pig's trotter during vertical movement is short, preventing heat accumulation to the point of causing burning. After splitting, the edges of the pig's trotter show no signs of burning or charring, maintaining a fresh and uniform color, and a normal, odorless smell.

[0021] 4. This utility model can improve operational efficiency and process convenience, and reduce overall processing costs. The symmetrical design of the straightening plate in this equipment ensures quick and accurate positioning of pig trotters. Workers only need to place and press down the handle to complete the splitting, without complicated adjustments. The material trough is detachable, allowing for continuous assembly line operation: material is taken from one side, split in half, and directly placed into the material trough on the other side, forming an efficient workflow.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0030] Example 1

[0031] To address the technical problems in the background section, the following pig by-product processing equipment is provided:

[0032] Combination Figures 1-6 As shown, a pig by-product processing equipment includes a rectangular frame structure operating platform 1, and a splitting mechanism 2 for splitting pig hooves in half is fixed on the top surface of the operating platform 1 along its short axis.

[0033] The splitting mechanism 2 includes a platform 21 fixed on the operating frame 1. The top surface of the platform 21 has a long strip-shaped cutting hole 211 extending through it along its long axis. A cutter 23 is inserted into the cutting hole 211 with gaps. One end of the cutter 23 is fixed to a long rod-shaped handle 231, and the other end is pivotally connected to a support plate 24 that is vertically and symmetrically fixed on both sides of the corresponding end of the cutting hole 211. A semi-cylindrical straightening plate 22 is vertically and symmetrically fixed on both sides of the cutting hole 211. The two straightening plates 22 are used together to longitudinally support the pig's hoof.

[0034] On the operating platform 1 located on both sides of the splitting mechanism 2, there are detachable material troughs 4. One material trough 4 is used to pile up unsplit pig trotters, and the other material trough 4 is used to pile up split pig trotters.

[0035] By adopting the above technical solution, this equipment can significantly improve the cross-sectional quality of pig trotters after splitting, enhancing the product's appearance and taste. The core of the splitting mechanism in this equipment is the cooperative design of the cutter 23 and the cutting hole 211. One end of the cutter 23 is fixed to the handle 231, and the other end is pivotally connected to the support plate 24, forming a lever-type operating mechanism. Two semi-cylindrical straightening plates 22 are vertically and symmetrically arranged on both sides of the cutting hole 211 to provide longitudinal support for the pig trotters.

[0036] During operation, the worker places the pig's hoof between two stabilizing plates 22, ensuring it is stably centered above the cutting hole 211. By pressing down the handle 231, the cutter 23 moves vertically downwards along the cutting hole 211, using the pivot point as a fulcrum, to perform a guillotine-like splitting motion on the pig's hoof. Compared to high-speed bone saws, this splitting method applies a vertical and uniform force, avoiding the pulling and friction of the high-speed rotating saw blade on the connective tissue of the pig's hoof.

[0037] Because the splitting force acts directly on the hard and cartilage of the pig's trotter, the soft tissue is not torn or deformed, resulting in a smoother, flatter cut surface and reduced burrs and damage. This directly improves the appearance and texture of the split pig's trotter after cooking, meeting the product quality requirements of the food processing and catering industries.

[0038] This device effectively reduces bone fragments and foreign object contamination, ensuring food safety and the eating experience. The design of the cutter 23 and the gap fit between the cutter hole 211 form a guide channel, ensuring that the splitting process is linear and controllable. At the same time, the semi-cylindrical shape of the straightening plate 22 stably restricts the position of the pig's hoof, preventing it from shifting during cutting.

[0039] The splitting process produces larger bone fragments and fewer fine bone chips because the sharp blade directly cleaves the bone and cartilage, unlike a bone saw which grinds bone through high-speed friction. The larger bone fragments are easier to remove in subsequent processing. Furthermore, the absence of high-speed moving parts avoids the generation of fine bone powder and debris from friction. This significantly reduces the risk of contamination of the meat by hard foreign objects, eliminating food safety hazards. At the same time, the meat is cleaner, retaining its natural flavor and enhancing the eating experience, making it particularly suitable for the high-end food industry with its stringent requirements for raw materials.

[0040] This equipment avoids heat damage, maintaining the stable color and aroma of pig trotters. The pivotal connection and manual operation mechanism of the cutting blade 23 make the splitting process controllable and slower. Simultaneously, the design of the cutting hole 211 guides the cutting blade 23 to move linearly, reducing the frictional contact area. Manual operation avoids the mechanical frictional heat generated by high-speed sawing, preventing a sudden increase in localized temperature on the cut surface. The short contact time between the cutting blade and the pig trotter during vertical movement prevents heat accumulation to the point of causing burning. After splitting, the edges of the pig trotter show no signs of burning or charring, maintaining a fresh and uniform color and a normal, odorless smell. This is beneficial for meat quality stability during subsequent refrigeration or freezing, reducing the risk of spoilage due to heat damage, ensuring frozen product quality, and meeting the requirements of cold chain logistics for product appearance and sensory characteristics.

[0041] This equipment improves operational efficiency and process convenience, while reducing overall processing costs. It comprises a rectangular frame operating platform 1, a centrally located splitting mechanism 2, and detachable feed troughs 4 on either side. The symmetrical design of the centering plate 22 ensures quick and accurate positioning of pig hooves; workers only need to place and press the handle to complete the splitting, eliminating the need for complex adjustments. The feed troughs 4 are detachable, allowing for continuous flow operations: feed is taken from one side, split, and directly placed into the feed trough 4 on the other side, forming a highly efficient workflow. This simplifies the operation process, reduces manual placement and positioning time, and increases throughput per unit time. Simultaneously, the equipment has a compact structure, is easy to maintain and clean, and can be integrated into existing slaughtering or processing lines, indirectly reducing labor costs and equipment energy consumption.

[0042] like Figure 2 and Figure 3 As shown, the top surface of the operating platform 1 is symmetrically fixed with support rods 11 at horizontal intervals along its short axis; the four corners of the platform 21 are symmetrically fixed with mounting blocks 25, and the mounting blocks 25 are fixedly screwed to the ends of the corresponding support rods 11 by fastening bolts 26.

[0043] By adopting the above technical solution, the mounting blocks 25 at the four corners of the platform 21 are fixedly connected to the ends of the support rods 11 by fastening bolts 26, forming a four-point rigid fixation; the vertical impact force generated during splitting is transmitted through the platform to the four mounting blocks 25, and then evenly distributed to the entire operating table 1 through the support rods 11, avoiding local stress concentration that could lead to deformation.

[0044] The mounting block 25 and the support rod 11 are detachably connected by fastening bolts 26; loosening the fastening bolts 26 can separate the platform 21 from the support rod 11, thus realizing the overall disassembly of the splitting mechanism.

[0045] like Figure 2 and Figure 6As shown, a support block 27 is vertically fixed to the top surface of the end of the platform 21 facing the handle 231, and the support block 27 and the cut hole 211 are on the same straight line; the top surface of the support block 27 has an arc-shaped groove, and a rubber pad 271 is fixedly attached to the inner wall of the groove.

[0046] By adopting the above technical solution, the grooved support block 27 is designed to provide flat support for the handle 231 of the cutter 23 after the cutter 23 has finished cutting, so as to prevent the handle 231 from bending and being damaged due to long-term cutting action; the rubber pad 271 is fixedly attached to the inner wall of the groove of the support block 27 to play a buffering and shock absorption role. The rubber pad 271 absorbs energy through elastic deformation and reduces hard impact.

[0047] like Figure 3 and Figure 4 As shown, a limit assembly 28 is provided on one side of the end of the cut hole 211 that is on the same side as the support plate 24;

[0048] The limiting component 28 includes a support plate 281 that is vertically fixed to the top surface of the platform 21. A limiting screw 282 is horizontally and vertically screwed through the support plate 281. When the handle 231 of the cutter 23 rests flat on the rubber pad 271 of the support block 27, the limiting screw 282 can be screwed into and engaged with the limiting groove 232 opened on the cutter 23.

[0049] By adopting the above technical solution, the limiting component 28 is set to prevent the cutter 23 from being opened when the equipment is not in use or during transportation, thus preventing accidents.

[0050] The limiting screw 282 is laterally screwed onto the support plate 281 and can be screwed in for adjustment. When the cutter 23 is fully returned to its original position, the limiting groove 232 is aligned with the axis of the limiting screw 282. Tightening the limiting screw 282 causes its end to embed into the limiting groove 232, forming a rigid mechanical interference that prevents the cutter 23 from rotating around the pivot of the support plate 24. Even if the equipment is tilted, vibrated, or the handle 231 is accidentally touched, the cutter 23 cannot be lifted due to the locking of the limiting screw 282. This fundamentally prevents cuts caused by the cutter accidentally springing open during equipment idleness, cleaning, or handling, and meets the safety requirements of food machinery.

[0051] like Figure 4 As shown, preferably, both the first support plate 24 and the second support plate 281 are L-shaped structures.

[0052] By adopting the above technical solution, the vertical part of support plate 24 is pivotally connected to the cutter 23, and the vertical part of support plate 281 is screwed with the limiting screw 282. Compared with the flat plate structure, the L-shaped cross-section has a higher moment of inertia, which can effectively resist the lever moment and impact load generated when the cutter 23 cleaves downward; the natural reinforcing ribs formed at the L-shaped bends distribute the load to the entire contact surface between the horizontal part and the platform 21, reducing stress concentration.

[0053] Example 2

[0054] Combination Figure 5 and Figure 6 As shown, based on the above embodiments, this embodiment further provides the following:

[0055] In this embodiment, the material trough 4 is a square trough structure, and an annular flange 41 is integrally provided around the edge of its top opening; the material trough 4 is detachably suspended from the top surface of the corresponding end of the operating table 1 by a matching support assembly 3.

[0056] The support assembly 3 includes a square frame 31 that is longitudinally engaged with the material trough 4, and the bottom surface of the annular flange 41 of the material trough 4 is in contact with the top surface of the square frame 31; a pair of inverted U-shaped hooks 32 are respectively vertically and symmetrically fixed on the two end faces of the square frame 31, and the hooks 32 are longitudinally engaged with the long side of the top surface of the operating table 1; a straight rod-shaped handle 33 is vertically fixed to the outer end face of the hooks 32.

[0057] By adopting the above technical solution, the supporting component 3 can not only enable the quick assembly and disassembly of the material trough 4, improving the continuity of operation, but also facilitate manual lifting and transportation.

[0058] The top opening of the feeding trough 4 is provided with an annular flange 41, forming a rigid load-bearing edge. The top surface of the square frame 31 of the support assembly 3 fits against the bottom surface of the annular flange 41, and the hook 32 locks onto the long side of the top surface of the operating platform 1. When the feeding trough 4 is placed inside the square frame 31, the annular flange 41 is limited to prevent detachment. After pressing down, the hook 32 automatically locks onto the edge of the platform due to elastic deformation. By grasping the handle 33 and lifting upwards, the hook 32 disengages from the platform, and the feeding trough 4 and the support assembly 3 can be lifted directly as a whole for easy transportation. This avoids the disassembly steps of traditional bolt-fixed tools, ensuring the high-frequency operation rhythm of the slaughtering production line.

[0059] Working principle and usage process of this utility model:

[0060] When using this utility model, firstly, place the unsplit pig's trotters into the left-side feeding trough 4; the operator stands on the side of the handle 231 of the splitting mechanism 2 and confirms that the cutter 23 is in the raised state.

[0061] Then, take a single pig's hoof from the left feed trough 4 and place it longitudinally between the two straightening plates 22, keeping the hoof tip facing upwards: hold the handle 231 with one hand and press down, the cutter 23 rotates around the pivot of the support plate 24 and cuts downwards, vertically penetrating the middle of the pig's hoof; when the handle 231 is pressed down until it falls flat on the support block 27, the lower part of the cutter 23 is completely embedded in the cutting hole 211, and the pig's hoof is split in half; the operator lifts the handle 231 upwards and picks up the two halves of the pig's hoof and puts them into the feed trough 4 on the right.

[0062] Repeat the above operation until the pig trotters in the left-side feeding trough 4 are chopped. The operator holds the handle 33 and lifts it upwards, the hook 32 disengages from the operating table 1, and the support assembly 3 and feeding trough 4, which are now full of chopped pig trotters, can be removed and transferred to the next process. When the operation is finished, press down the handle 231 onto the support block 27, tighten the limit screw 282 to engage the limit groove 232, and lock the cutter 23 to prevent accidental opening.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
