Description

Technical Field

[0001] This invention belongs to the field of crushing device technology, and in particular relates to a protein extraction and crushing device. Background Technology

[0002] Protein extraction and crushing equipment is a core auxiliary device in food processing, biomedicine, and feed production. Its core function is to crush animal bones, making it easier to extract effective components such as bone marrow protein and collagen. The crushing effect, operational stability, and material recovery efficiency directly determine the purity, yield, and production safety of the extracted protein. The core technical requirements for this equipment are: stable crushing process, reasonable handling of fragments, avoidance of noise pollution and equipment damage, efficient recovery of effective components such as bone marrow protein, and suitability for large-scale continuous production.

[0003] While current animal bone protein extraction and crushing devices on the market can achieve basic bone crushing, they have significant technical shortcomings in areas such as fragment handling, noise control, and recovery of active ingredients, making it difficult to meet the demands of large-scale production and high-quality extraction. Specific technical deficiencies are as follows: Firstly, existing crushing devices lack effective buffer and support structures. After the skeleton is crushed, the fragments fall directly and freely into the equipment, colliding violently with the inner wall or receiving parts, generating harsh noise. This not only affects the operating environment but may also damage the hearing of operators, failing to meet relevant environmental protection and safe production requirements.

[0004] Secondly, bone fragments are hard and heavy, and when they fall freely after breaking, they have a large impact force. If there is no buffer protection structure, they can easily damage the core components inside the equipment, such as the material guiding parts and detection elements, leading to frequent equipment failures, increased maintenance costs, and affecting the continuity of production.

[0005] Third, bone marrow in animal bones is rich in protein and is one of the core sources of protein extraction. However, existing crushing devices do not have a dedicated recovery structure. During the crushing process, bone marrow is easily dropped or scattered with the fragments, or adheres to the inner wall of the equipment, making it impossible to collect effectively. This results in a large loss of bone marrow protein, which not only reduces the yield of protein extraction but also increases raw material loss and raises the total production cost.

[0006] Fourth, the existing equipment does not have a suitable buffer receiving component. When fragments fall, there is no buffer or guidance, which not only amplifies the risk of noise and equipment damage, but also makes it impossible to collect effective components such as bone marrow. At the same time, the lack of a dedicated material guiding and recycling structure makes bone marrow protein easy to remain in the gaps of the equipment, which not only wastes resources, but also breeds bacteria and affects the quality of products produced in subsequent production.

[0007] Fifth, existing equipment focuses on crushing efficiency while neglecting the coordinated design of fragment disposal, noise control, and component recovery. This results in a failure to balance crushing, noise reduction, and recovery, which affects the production environment and equipment lifespan, as well as reduces the economic efficiency and practicality of protein extraction, becoming a key bottleneck restricting the high-quality development of the protein extraction industry.

[0008] As the protein extraction industry continues to raise its requirements for product quality, production efficiency, and environmental safety, the shortcomings of existing crushing devices, such as "high noise, easy equipment damage, and low recovery rate of effective components," are becoming increasingly prominent. There is an urgent need to develop a new type of crushing device that can solve the above pain points and achieve fragment buffering, noise control, bone marrow protein recovery, and equipment protection to meet the needs of large-scale, high-quality protein extraction. Summary of the Invention

[0009] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0010] In order to overcome the shortcomings of the prior art, the present invention provides a protein extraction and crushing device.

[0011] To achieve the above objectives, the present invention adopts the following technical solution: a protein extraction and disruption device, comprising: The box has a processing cavity for crushing animal bones, with a feed inlet on the top and a discharge outlet on the side wall; Two sets of crushing rollers are arranged adjacently in the processing cavity. The crushing rollers are located below the feed inlet, and a gap is left between the two sets of crushing rollers to crush the animal bones falling from the feed inlet. The receiving mesh is located below the crushing roller. The receiving mesh is made of elastic material and has multiple material discharge holes. The guide plate is located below the receiving mesh and is inclined inside the processing cavity; The lifting structure is located at one end of the receiving mesh to lift one side of the receiving mesh, so that the receiving mesh forms an inclined surface facing the discharge port; when the receiving mesh forms an inclined surface, the receiving mesh is in a taut state.

[0012] The protein extraction and crushing device also includes a connecting structure. The connecting structure and the lifting structure are respectively located on both sides of the box. The connecting structure is located on one side of the discharge port.

[0013] Furthermore, a first connecting box communicating with the processing cavity is provided on the side wall of the box. The connecting structure is a first spool located inside the first connecting box. The first spool is rotatably connected to the first connecting box. A first groove is provided on the first spool. A connecting rod is provided in the first groove. A first connecting rope is provided on the receiving net. One end of the first connecting rope is fixed to the connecting rod.

[0014] Furthermore, a second connecting box communicating with the processing cavity is provided on the side wall of the box. The lifting structure includes a guide rail, a first slider, a second slider, a connecting block, and a second spool located in the second connecting box. The guide rail is fixed to the inner wall of the second connecting box. The first slider and the second slider are slidably connected to the guide rail. The first slider and the second slider are connected by a fourth spring. The connecting block is fixed to the second slider. The connecting block has a through cavity. The second spool passes through the through cavity. The second spool has a second groove. A second connecting rope is provided on the receiving net. One end of the second connecting rope is fixed to the second groove.

[0015] Furthermore, the lifting structure also includes a third spool and a first motor. The first motor is driven by the third spool. The third spool is provided with a third groove, and a first pull rope is provided in the third groove. The first pull rope passes through the second connecting box and is fixed to the first slider.

[0016] Furthermore, a first drive shaft is provided on the first spool, and the first drive shaft passes through the first connecting box; a second drive shaft is provided on the second spool, and the second drive shaft passes through the second connecting box; a transmission plate is provided on the side wall of the box to drive and cooperate with the first drive shaft and the second drive shaft.

[0017] Furthermore, a fourth spool is connected to the output shaft of the first motor. The fourth spool has a fourth groove, and a second pull rope is fixedly connected inside the fourth groove. One end of the second pull rope is fixedly connected to the transmission plate, and the length of the second pull rope is much greater than the length of the first pull rope.

[0018] Furthermore, one end of the fourth spool is provided with an extension rod, on which a transmission tube is sleeved. One end of the extension rod is provided with a first spring, and one end of the first spring abuts against the transmission tube. The third spool is provided with a transmission cavity corresponding to the transmission tube. A fixed rod is slidably connected to the side wall of the housing. The transmission tube is rotatably connected to the fixed rod. One end of the fixed rod is provided with an electromagnet. When the electromagnet is energized, it can push the fixed rod into the transmission cavity and push the transmission tube out of the transmission cavity.

[0019] Furthermore, the second slider is positioned above the first slider, and a stop block is provided on the inner wall of the guide rail. The second slider has a through groove corresponding to the stop block. The first slider has a movable groove, in which a fixed block and a connecting plate are provided. The fixed block and the connecting plate are connected by a second spring. The inner wall of the guide rail has a fixed groove corresponding to the fixed block. The first slider has a movable cavity communicating with the movable groove, in which a push block is provided. The push block has a guide groove and a third spring. One end of the first pull rope is fixed to the top of the push block.

[0020] Furthermore, a reel is provided on the side wall of the housing, which is located below the second connecting box. A third pull rope is provided at the bottom of the connecting block, and the other end of the third pull rope is wound around the reel. A second motor and a third drive shaft are also provided on the side wall of the housing. The reel is provided with a drive groove corresponding to the third drive shaft, and the second motor and the third drive shaft are engaged in transmission.

[0021] The advantages of this invention are: By setting up a flexible mesh to catch the fragments, combined with an inclined guide structure, the impact of falling bone fragments can be buffered, preventing the fragments from colliding violently with the internal components of the equipment. This completely solves the problem of the ear-piercing noise caused by the free-falling fragments in existing equipment. At the same time, it prevents the fragments from damaging the internal guide and detection equipment, protecting the equipment, extending its service life, reducing maintenance costs, and meeting environmental protection and safe production requirements.

[0022] By combining the receiving mesh and the guiding structure, bone marrow protein flowing out of the bone during the crushing process can be effectively collected, preventing bone marrow from scattering with the fragments and adhering to the inner wall of the equipment, thus minimizing protein loss, increasing protein extraction rate, reducing raw material loss, and improving production economy. At the same time, it prevents bacteria from growing on the bone marrow residue, ensuring the purity of subsequent protein extraction.

[0023] By rationally arranging the crushing rollers and receiving structure, the animal bones are crushed evenly, avoiding incomplete protein extraction caused by incomplete crushing. At the same time, the inclined guide design can guide the crushed material (including bone marrow protein) to be transported smoothly, avoiding accumulation and blockage, adapting to the needs of large-scale production, and greatly improving the efficiency and quality of protein extraction.

[0024] The flexible support mesh and inclined guide structure are adaptable to different crushing requirements without the need for complete equipment replacement. At the same time, the operation process is simplified, and no complicated manual intervention is required, which reduces the labor intensity of operators. It is suitable for protein extraction scenarios in multiple fields such as food and biomedicine, and improves the practicality and versatility of the equipment.

[0025] This application retains the efficient crushing function and, through the design of buffer receiving and smooth material guiding, achieves integrated crushing, recycling and conveying, avoiding problems such as fragment accumulation and equipment blockage, while extending the service life of the equipment, enhancing the market competitiveness of the product, and meeting the needs of large-scale, high-quality protein extraction production.

[0047] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] like Figure 1-13 As shown, a protein extraction and crushing device includes a housing 101, two sets of crushing rollers 114, a receiving net 115, a guide plate 116, a lifting structure, and a connecting structure.

[0049] The housing 101 has a processing cavity for crushing animal bones. The top of the housing 101 is provided with a feed inlet 102, and the side wall is provided with a discharge outlet 106. Two sets of crushing rollers 114 are arranged adjacent to each other in the processing cavity. The crushing rollers 114 are located below the feed inlet 102, and a gap is left between the two sets of crushing rollers 114 to crush the animal bones falling from the feed inlet 102. A receiving net 115 is provided below the crushing rollers 114. The receiving net 115 is made of elastic material and has multiple discharge holes. A guide plate 116 is provided below the receiving net 115 and is inclined in the processing cavity. A lifting structure is provided at one end of the receiving net 115 to lift one side of the receiving net 115, so that the receiving net 115 forms an inclined surface facing the discharge outlet 106. When the receiving net 115 forms an inclined surface, the receiving net 115 is in a taut state. When the bone is crushed, the receiving mesh 115 is in a relaxed state. Bone fragments falling onto the receiving mesh 115 cause it to deform, thus buffering the impact of the fragments and effectively reducing noise. The soft contact between the buffer mesh and the bone fragments avoids the violent collision noise caused by hard contact. Simultaneously, the elastic deformation also forms a wrapping support for the fragments, reducing secondary impacts caused by fragment splashing. After crushing is complete, the lifting structure moves, raising one side of the receiving mesh 115. With the cooperation of the connecting structure, the receiving mesh 115 forms a taut inclined surface facing the discharge port 106. At this time, the fragments slide down the inclined surface under their own gravity to the discharge port 106 for discharge, while liquid or semi-liquid active ingredients such as bone marrow drip through the drop holes on the receiving mesh 115 onto the inclined guide plate 116 below, converging and collecting along the guide plate 116, achieving the separation and recovery of fragments and bone marrow protein. The receiving mesh 115 is woven from highly elastic rubber or elastic fibers. Its elastic deformation capability ensures a buffering effect on fragments of different weights. The design of multiple discharge holes allows for the smooth passage of components such as bone marrow while effectively intercepting larger bone fragments, preventing them from clogging the discharge holes or falling directly onto the guide plate 116 and causing impact. The tilt angle of the guide plate 116 is set between 30 and 45 degrees to ensure that components such as bone marrow flow smoothly under gravity, minimizing residue. The surface of the guide plate 116 can also be polished or coated with a non-stick coating to further reduce bone marrow adhesion and improve recycling efficiency.

[0050] The connecting structure and the lifting structure are respectively located on both sides of the housing 101. The connecting structure is located on one side of the discharge port 106. When the lifting structure raises one side of the receiving mesh 115, the other side of the receiving mesh 115 rotates around the connecting structure to form an inclined surface. The connecting structure positions the bottom end of the inclined surface formed by the receiving mesh 115, thereby ensuring that the fragments can accurately slide down the inclined surface to the discharge port 106.

[0051] Specifically, such as Figure 2 , Figure 3As shown, a first connecting box 103 communicating with the processing cavity is provided on the side wall of the box 101. The connecting structure is a first spool 117 located inside the first connecting box 103. The first spool 117 is rotatably connected to the first connecting box 103. A first groove 1171 is provided on the first spool 117, and a connecting rod 118 is provided in the first groove 1171. A first connecting rope 119 is provided on the receiving net 115, and one end of the first connecting rope 119 is fixed to the connecting rod 118. When the receiving net 115 is in a relaxed state, the first spool 117 can rotate freely, allowing the first connecting rope 119 to freely extend and retract with the deformation of the receiving net 115, thus avoiding limiting the cushioning effect of the receiving net 115. When the lifting structure raises one side of the receiving net 115, the first spool 117 rotates to wind up the first connecting rope 119, ensuring that the receiving net 115 can form a stable taut slope. The first groove 1171 is designed to limit the connecting rod 118, preventing the first connecting rope 119 from shifting or tangling during deployment and retraction, thus ensuring the stable operation of the connection structure. The connection points of the connecting rod 118 and the first connecting rope 119 are evenly distributed on the edge of the receiving net 115 near the discharge port 106, ensuring that the receiving net 115 is subjected to uniform force during lifting, avoiding damage to the receiving net 115 or inconsistent tilt angles due to excessive local force.

[0052] Furthermore, such as Figure 4 , Figure 5As shown, a second connecting box 104 communicating with the processing cavity is provided on the side wall of the housing 101. The lifting structure includes a guide rail 156, a first slider 139, a second slider 140, a connecting block 131, and a second spool 133 disposed in the second connecting box 104. The guide rail 156 is fixed to the inner wall of the second connecting box 104. The first slider 139 and the second slider 140 are slidably connected to the guide rail 156, respectively. The first slider 139 and the second slider 140 are connected by a fourth spring 141. The connecting block 131 is fixedly connected to the second slider 140. The connecting block 131 has a through cavity, and the second spool 133 passes through the through cavity. The second spool 133 has a second groove 1331. The receiving net 115 has a second connecting rope 132. One end of the second connecting rope 132 is fixedly connected to the second groove 1331. One end of the second spool 133 has a limiting plate 134 to limit the connection position of the second spool 133 and prevent the second spool 133 from directly passing through the through cavity. When the lifting structure is activated, the first slider 139 and the second slider 140 slide upward along the guide rail 156, driving the connecting block 131 and the second spool 133 to rise, thereby pulling one side of the receiving net 115 upward through the second connecting rope 132. The design of the second groove 1331 is similar to that of the first groove 1171, used to guide and limit the second connecting rope 132 to prevent it from falling off or getting tangled during movement. The cavity allows the second spool 133 to rotate freely within the connecting block 131. When the receiving net 115 deforms during the buffering process, the second spool 133 can rotate accordingly to release or rewind the second connecting rope 132, thus avoiding obstruction to the elastic deformation of the receiving net 115.

[0053] like Figure 1 , Figure 4 As shown, the lifting structure also includes a third spool 124 and a first motor 123. The first motor 123 is driven by the third spool 124. The third spool 124 has a third groove 1241, and a first pull rope 113 is installed in the third groove 1241. The first pull rope 113 passes through the second connecting box 104 and is fixed to the first slider 139. When the first motor 123 starts, it drives the third spool 124 to rotate, and winds up the first pull rope 113 through the third groove 1241. The first pull rope 113 pulls the first slider 139 to slide upward along the guide rail 156, thereby driving the second slider 140, the connecting block 131, and the second spool 133 to rise synchronously, realizing the lifting of one side of the receiving net 115. The forward and reverse rotation of the first motor 123 can control the third spool 124 to perform the rope winding and unwinding action, thereby controlling the lifting and lowering of the receiving net 115. The operation is convenient and the response is rapid.

[0054] like Figure 1 , Figure 11As shown, a first drive shaft 121 is mounted on a first spool 117, and the first drive shaft 121 extends out of a first connecting box 103; a second drive shaft 135 is mounted on a second spool 133, and the second drive shaft 135 extends out of a second connecting box 104. A transmission plate 120 is mounted on the side wall of the box 101 to drive the first drive shaft 121 and the second drive shaft 135. The transmission plate 120 has a first tooth, and the first drive shaft 121 and the second drive shaft 135 each have a second tooth, which mesh with each other. When the transmission plate 120 moves, it can simultaneously drive the first transmission shaft 121 and the second transmission shaft 135 to rotate, thereby causing the first spool 117 and the second spool 133 to synchronously wind up the first connecting rope 119 and the second connecting rope 132, providing tension to the receiving net 115 from both sides, ensuring that the receiving net 115 can be evenly tightened when forming an inclined surface, and avoiding the receiving net 115 from tilting or becoming loose in some areas due to asynchronous winding on both sides, which would affect the smoothness of the fragments sliding down.

[0055] like Figure 1 , Figure 9 , Figure 10 As shown, a fourth spool 125 is connected to the output shaft of the first motor 123. A fourth groove 1251 is provided on the fourth spool 125. A second pull rope 122 is fixedly connected in the fourth groove 1251. One end of the second pull rope 122 is fixedly connected to the transmission plate 120. The length of the second pull rope 122 is much greater than the length of the first pull rope 113. An extension rod 127 is provided at one end of the fourth spool 125. A transmission tube 126 is sleeved on the extension rod 127. A first spring 128 is provided at one end of the extension rod 127. One end of the first spring 128 abuts against the transmission tube 126. A transmission cavity corresponding to the transmission tube 126 is provided on the third spool 124. A fixed rod 129 is slidably connected to the side wall of the housing 101. The transmission tube 126 is rotatably connected to the fixed rod 129. An electromagnet 130 is also provided on the side wall of the housing 101. The electromagnet 130 is located on one side of the fixed rod 129. A magnetic block is provided on the fixed rod 129. When the electromagnet 130 is energized, it can push the fixed rod 129 into the transmission cavity and push the transmission tube 126 out of the transmission cavity.

[0056] When the electromagnet 130 is not energized, under the elastic force of the first spring 128, the transmission tube 126 is engaged in the transmission cavity of the third spool 124. At this time, the third spool 124 and the extension rod 127 are connected by transmission tube 126. The first motor 123 works and simultaneously drives the third spool 124 and the fourth spool 125 to rotate. Since the length of the second pull rope 122 is much greater than the length of the first pull rope 113, the second pull rope 122 will not pull the transmission plate 120 to move when the first pull rope 113 pulls the first slider 139 to move. The first slider 139 and the second slider 140 slide upward along the guide rail 156 to achieve the lifting of one side of the receiving net 115. When the first slider 139 and the second slider 140 move, the second drive shaft 135 moves relative to the drive plate 120, causing the second drive shaft 135 to rotate in one direction during the upward movement, and the receiving net 115 changes from a relaxed state to a taut state. After the second slider 140 moves to the top of the guide rail 156, the electromagnet 130 is energized to drive the fixing rod 129 to move. The fixing rod 129 drives the drive tube 126 to overcome the elastic force of the first spring 128 and exit from the drive cavity. At this time, the transmission connection between the third spool 124 and the extension rod 127 is cut off, and the third spool 124 is fixed in the current position by the fixing rod 129. The first motor 123 drives the fourth spool 125 to continue winding. The second pull rope 122 pulls the transmission plate 120 towards the top of the housing 101. The transmission plate 120 drives the first transmission shaft 121 to rotate and drives the second transmission shaft 135 to rotate in the opposite direction. When the first spool 117 rotates with the first transmission shaft 121, it winds up the first connecting rope 119. The first connecting rope 119 is used to tighten one side of the receiving net 115. The second spool 133 rotates with the second transmission shaft 135, causing the other side of the receiving net 115 to go from a taut state to a slack state and then back to a taut state. This adjusts the overall state of the receiving net 115, making it easier to discharge the bone fragments on the receiving net 115 along the surface of the receiving net 115 and preventing the bone fragments from getting stuck in the discharge hole of the receiving net 115.

[0057] When the receiving net 115 needs to be lowered, the first motor 123 reverses, the fourth spool 125 releases the second pull rope 122, the transmission plate 120 moves in the opposite direction under its own gravity, driving the first spool 117 and the second spool 133 to release the connecting rope, at the same time the electromagnet 130 is de-energized, causing the fixing rod 129 to move out of the transmission cavity, the third spool 124 releases the first pull rope 113, and the slider slides down along the guide rail 156 under the action of gravity, and the receiving net 115 returns to a relaxed state.

[0058] Preferred, such as Figure 1 , Figure 11As shown, a third connecting box 112 is provided on the side wall of the housing 101. The first motor 123, the third spool 124, the fourth spool 125, the fixing rod 129, and other components are all housed within the third connecting box 112. A mounting block is provided on the side wall of the housing 101, and a sliding groove 158 is provided on the mounting block. A third slider 157 is provided on the fixing rod 129, and the third slider 157 is slidably connected within the sliding groove 158, achieving a sliding connection between the fixing rod 129 and the side wall of the housing 101. A protective cover 111 is provided on the side wall of the housing 101, and the transmission plate 120 is located within the protective cover 111. The protective cover 111 protects the transmission plate 120, the first transmission shaft 121, and the second transmission shaft 135.

[0059] Furthermore, such as Figure 7 , Figure 8 As shown, the second slider 140 is located above the first slider 139. A stop block 149 is provided on the inner wall of the guide rail 156. The second slider 140 is provided with a through groove 148 corresponding to the stop block 149. The first slider 139 is provided with a movable groove. A fixed block 142 and a connecting plate 144 are provided in the movable groove. The fixed block 142 and the connecting plate 144 are connected by a second spring 143. A fixed groove 150 corresponding to the fixed block 142 is provided on the inner wall of the guide rail 156. The first slider 139 is provided with a movable cavity 159 communicating with the movable groove. The movable cavity 159 is located below the movable groove. A push block 145 is provided in the movable cavity 159. A guide groove 147 and a third spring 146 are provided on the push block 145. The third spring 146 is fixedly connected to the bottom of the movable cavity 159. One end of the first pull rope 113 is fixedly connected to the top of the push block 145.

[0060] like Figure 1 , Figure 12 , Figure 13As shown, a spool 137 is provided on the side wall of the housing 101. The spool 137 is located below the second connecting box 104. A third pull rope 136 is provided at the bottom of the connecting block 131. The other end of the third pull rope 136 is wound around the spool 137. A second motor 152 and a third drive shaft 153 are also provided on the side wall of the housing 101. The spool 137 is provided with a drive groove corresponding to the third drive shaft 153. The second motor 152 and the third drive shaft 153 are in drive cooperation. Specifically, there are two sets of first connecting boxes 103 and second connecting boxes 104 respectively. The two sets of first connecting boxes 103 and second connecting boxes 104 are respectively located on both sides of the box body 101. A fourth connecting box 151 is provided on the side wall of the box body 101. The second motor 152 is fixedly connected to the fourth connecting box 151. The side wall of the fourth connecting box 151 extends to the bottom of the second connecting box 104. A first transmission wheel 154 is provided at one end of the third transmission shaft 153. The first transmission wheel 154 is rotatably connected to the extension of the fourth connecting box 151. A second transmission wheel 155 is connected to the output shaft of the second motor 152. The first transmission wheel 154 and the second transmission wheel 155 rotate synchronously through the synchronous belt 138. The second transmission wheel 155 is an incomplete gear. Therefore, when the second motor 152 drives the second transmission wheel 155 to rotate, it drives the synchronous belt 138 to rotate intermittently.

[0061] like Figure 7 , Figure 8 , Figure 12 , Figure 13As shown, when the third spool 124 rotates and pulls the first pull rope 113, the first pull rope 113 pulls the push block 145 to move. The fixed block 142 is stuck against the side wall of the guide rail 156 and cannot move. The push block 145 drives the first slider 139 to move within the guide rail 156. The second slider 140 moves together with the first slider 139. When the second slider 140 moves to the position of the stop block 149, the stop block 149 passes directly through the through groove 148, causing the second slider 140 to continue to rise until the top surface of the first slider 139 touches the bottom surface of the stop block 149. At this time, the first slider 139 stops moving. At this time, the fixed block 142 is on one side of the fixed groove 150. The push block 145 continues to move upward under the continuous pull of the first pull rope 113. The inclined surface of the guide groove 147 presses against the fixed block 142. The fixing block 142 overcomes the elastic force of the second spring 143 and moves out of the movable groove. The fixing block 142 is inserted into the fixing groove 150 to fix the first slider 139. At this time, the second motor 152 drives the third transmission shaft to rotate. When the reel 137 rotates, the third pull rope 136 pulls the second slider 140 towards the first slider 139. As the third transmission shaft rotates intermittently under the action of the second transmission wheel 155, the second slider 140 loses its pulling force after being pulled down a certain distance. The second slider 140 bounces up quickly under the action of the fourth spring 141, thereby generating vibration on the receiving net 115. Through this intermittent vibration, the small bone fragments attached to the receiving net 115 can be shaken off, preventing bone fragments from remaining and affecting the subsequent separation effect. Specifically, when the second slider 140 is pulled down by the third rope 136, it compresses the fourth spring 141, accumulating elastic potential energy. When the reel 137 stops rotating, the tension of the third rope 136 disappears, and the fourth spring 141 quickly releases its potential energy, causing the second slider 140 to bounce upwards. This, in turn, drives the receiving net 115 to move upwards instantaneously through the second connecting rope 132. Subsequently, it falls back under its own elasticity and the gravity of the bone fragments, forming a vibration. This vibration not only effectively removes bone fragments from the surface of the receiving net 115 but also helps to dislodge small bone fragments stuck at the edge of the discharge hole, ensuring the discharge hole is unobstructed and allowing liquid components such as bone marrow to drip smoothly onto the guide plate 116. At the same time, since the second transmission wheel 155 is an incomplete gear, the frequency and amplitude of the vibration can be adjusted by the rotation speed of the second motor 152 and the tooth profile design of the incomplete gear to adapt to the processing needs of bone fragments of different sizes and properties.

[0062] When the first pull rope 113 is wound off the third spool 124, the third spring 146 pulls the push block 145 to move to the bottom of the movable cavity, and the second spring 143 pulls the fixed block 142 to move into the movable groove, so that the fixed block 142 is dislodged from the fixed groove 150, and the first slider 139 moves down along the guide rail 156 to reset.

[0063] The inclined and taut nature of the receiving mesh 115 dislodges bone fragments, while the intermittent vibration of the mesh further enhances the thoroughness of fragment removal. Once the receiving mesh 115 forms a taut inclined surface facing the discharge port 106, larger bone fragments slide down the inclined surface under their own gravity, while smaller fragments that may be attached to the surface of the receiving mesh 115 due to surface tension or slight jamming are shaken off by the vibration generated by the second slider 140. This vibration is not continuous but is intermittently triggered by the characteristics of incomplete gears driven by the second motor 152. This avoids energy waste and excessive equipment wear that might result from continuous vibration, and allows for targeted removal of residual bone fragments during the critical discharge stage. The instantaneous impact of the vibration breaks the adhesion between the small bone fragments and the receiving mesh 115, causing them to slide down the inclined surface. In addition, vibration can also clear the discharge holes of the receiving mesh 115. For tiny bone fragments that may be stuck in the discharge holes and whose size is between the discharge hole diameter and the intercepted fragments, vibration can cause them to shift. They can either pass completely through the discharge hole (if the size is small enough) or be vibrated and slide down the slope again. This effectively prevents local blockage of the discharge holes and ensures the smooth infiltration and collection of liquid components such as bone marrow, thereby improving the efficiency and effect of solid-liquid separation in the protein extraction process as a whole.

[0064] Further preferred, such as Figure 1 , Figure 11 As shown, the front and rear sides of the housing 101 are configured as detachable side plates 105. The side plates 105 also serve as the side walls of the first connecting box 103 and the second connecting box 104, thereby facilitating the assembly and disassembly of the first spool 117, the second spool 133, the receiving net 115, and the guide plate 116.

[0065] like Figure 1 As shown, a support block is provided on the inner wall of the box 101, and the guide plate 116 is positioned on the support block. Additionally, a discharge port 109 and a receiving box 110 are provided on the side wall of the box 101. The discharge port 109 is located at the bottom end of the inclined surface of the guide plate 116, and the receiving box 110 is located at the discharge port 109. The receiving box 110 is used to collect liquid components such as bone marrow that slide down from the guide plate 116, achieving the collection of key liquid products during protein extraction. A discharge port 106 is provided on the side plate 105, and a support plate 107 is provided on the side plate 105. A collection box 108 is provided on the support plate 107, located at the discharge port 106, and is used to collect bone fragments discharged from the discharge port 106, achieving centralized collection of solid waste after solid-liquid separation.
