Description

Technical Field

[0001] This utility model relates to the field of bait processing technology, and more specifically, to a grinding device for bait processing. Background Technology

[0002] Feed processing is a crucial step in aquaculture, aiming to provide nutrient-rich, easily digestible feed to promote the healthy growth of farmed organisms. Grinding is a key step in feed production, involving the refining of raw materials (such as fishmeal, soybean meal, and corn) into a uniform, fine paste for subsequent processing or direct feeding. High-quality grinding not only improves the nutritional value and palatability of the feed but also enhances its water stability, reducing nutrient loss and thus improving aquaculture efficiency and economic benefits.

[0003] Existing bait processing grinding devices, while achieving a process from coarse to fine grinding by repeatedly grinding the bait with grinding balls inside the bait processing tank, rely solely on the movement of the grinding balls to complete the entire grinding process. Over time, this can lead to some bait remaining unground and accumulating inside the tank, thus reducing overall grinding efficiency and equipment performance.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a grinding device for bait processing to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Furthermore, in order to effectively promote the dissipation of heat inside the working chamber, a heat dissipation hole is provided on one side of the working chamber to cooperate with the grinding assembly.

[0008] Furthermore, to refine the material through progressive grinding and effectively improve the fineness of the slurry, the grinding assembly includes, from top to bottom, a first drive component, a fixed plate, a first grinding component, a cross bracket for the second grinding component, and a second drive component, all arranged sequentially inside the working chamber. The first and second grinding components cooperate with each other. The first and second drive components have the same structural principle. The first drive component includes a sleeve located at the top center of the fixed plate. The outer circumference of the sleeve is provided with a bearing that cooperates with the fixed plate. The bottom circumference of the sleeve is symmetrically provided with keys that cooperate with the first grinding component. A driven gear is sleeved on the top circumference of the sleeve. A drive gear is meshed on one side of the driven gear. A rotating shaft is sleeved on the inner circumference of the drive gear. The rotating shaft passes through a mounting bracket located at the top of the fixed plate and is connected to the output end of a servo motor. The diameter of the feed pipe is smaller than the diameter of the sleeve. The first grinding component includes an annular slide block disposed inside a fixed plate, with an annular slide rail fitted to the inner circumference of the annular slide block; a first grinding wheel is disposed at the bottom of the annular slide rail, with a conical groove at the bottom of the first grinding wheel, and first grinding holes arranged in a circular pattern inside the conical groove; a feeding hole is disposed at the center of the top of the first grinding wheel, which mates with the first grinding wheel, and a keyway is disposed on the outer circumference of the feeding hole, which mates with a key.

The slope of the conical groove is greater than the slope of the conical protrusion.

[0009] Furthermore, in order to reduce wear, deformation or cracking of the feed pipe after long-term use, the buffer assembly includes several circumferentially arranged support columns set on the outer circumference of the feed pipe, and the other end of each support column is connected to a buffer cone.

[0010] Furthermore, to facilitate real-time monitoring and operation control of the equipment's status by users, a control panel is provided on one side of the work box.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model has a reasonable and reliable structure and is simple to operate. Through the synergistic effect of the buffer component and the grinding component, it achieves highly efficient optimization of material conveying and processing. Specifically, the buffer component provides precise and efficient buffering of the material conveyed by the feeding pipe. Simultaneously, the grinding component adopts a dual-drive forward and reverse rotation structure, precisely driving the conical structures of the first and second grinding components to generate relative motion. The slope difference between the conical grooves and conical protrusions creates a gradual grinding gap. Combined with circumferentially arranged grinding holes to increase the contact area, the shearing and grinding forces generated by the forward and reverse rotation drive achieve highly efficient and refined grinding of the material, effectively improving grinding efficiency and the quality of the finished slurry, meeting the fine requirements of bait processing.

[0012] 2. By setting up a buffer component, when the material is conveyed at high speed from the feeding pipe, the buffer cone can directly bear the impact force of the material and disperse the kinetic energy through its own cone-shaped structure, avoiding the material from directly hitting the inner wall of the feeding pipe due to gravity or conveying pressure, reducing wear, deformation or cracking of the feeding pipe after long-term use, and extending the service life of the feeding pipe.

[0013] 3. This utility model, by setting up a grinding assembly, enables efficient and fine grinding of materials conveyed by the feeding pipe. Utilizing the forward and reverse rotation drive structure design of the first and second drive components, the conical structures of the first and second grinding components can move in both directions. The gradual grinding gap formed by the slope difference between the conical grooves and conical protrusions allows for progressively finer grinding of the material, effectively improving the fineness of the slurry. Simultaneously, the circumferential arrangement of the first and second grinding holes increases the material grinding contact area, and combined with the relative motion generated by the forward and reverse drive, further improves grinding efficiency.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of the present invention, a grinding device for bait processing is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-9As shown, a grinding device for bait processing according to an embodiment of the present invention includes a working box 1; a feeding pipe 2, disposed at the middle position of the top of the working box 1; a conveying hopper 8, disposed at the top of the feeding pipe 2; a buffer assembly 3, disposed on the inner circumference of the feeding pipe 2; a grinding assembly 4, disposed inside the working box 1 and cooperating with the feeding pipe 2, for receiving the material conveyed by the feeding pipe 2 and performing grinding operations; a collecting hopper 5, disposed inside the working box 1 and located at the bottom of the grinding assembly 4; and a collecting box 6, disposed at the bottom of the working box 1 and cooperating with the collecting hopper 5.

[0020] By employing the aforementioned technical solution, the synergistic effect of the buffer component 3 and the grinding component 4 achieves highly efficient optimization of material conveying and processing. Specifically, the buffer component 3 provides precise and efficient buffering of the material conveyed by the feed pipe 2. Simultaneously, the grinding component 4 adopts a dual-drive forward and reverse rotation structure, precisely driving the relative movement of the conical structures of the first grinding component 403 and the second grinding component 404. The slope difference between the conical groove 4034 and the conical protrusion 4044 creates a gradual grinding gap. Combined with the circumferentially arranged grinding holes to increase the contact area, the shearing and grinding forces generated by the forward and reverse rotation drive achieve highly efficient and refined grinding of the material, effectively improving grinding efficiency and the quality of the finished slurry, meeting the fine requirements of bait processing.

[0021] Specifically, the control panel 9 is equipped with a human-machine interface (HMI) and a PLC (Programmable Logic Controller). The HMI is the interface between the operator and the automation system. Its main function is to display the real-time operating status and the input of control commands. The PLC is used to execute specific control tasks, such as switch and sensor signal acquisition and processing.

[0022] In one embodiment, the working chamber 1 is provided with a heat dissipation hole 7 on one side to cooperate with the grinding assembly 4. This effectively promotes the dissipation of heat inside the working chamber 1.

[0023] In one embodiment, the above-mentioned grinding assembly 4 includes a first drive member 401, a fixing plate 402, a first grinding member 403, a second grinding member 404, a cross bracket 405, and a second drive member 406 arranged sequentially from top to bottom inside the working box 1, and the first grinding member 403 and the second grinding member 404 cooperate with each other; the first drive member 401 and the second drive member 406 have the same structural principle. The first driving component 401 includes a sleeve 4012 positioned at the top center of the fixed plate 402. A bearing 4013, which mates with the fixed plate 402, is provided on the outer circumference of the sleeve 4012. Keys 4014, which mate with the first grinding component 403, are symmetrically arranged on the bottom circumference of the sleeve 4012. A driven gear 4015 is fitted onto the top circumference of the sleeve 4012. A driving gear 4016 meshes with one side of the driven gear 4015. A rotating shaft 4017 is fitted onto the inner circumference of the driving gear 4016. The rotating shaft 4017 passes through a mounting bracket 4018 located at the top of the fixed plate 402 and is connected to the output end of a servo motor 4011. The diameter of the feed pipe 2 is smaller than the diameter of the sleeve 4012. The first grinding component 403 includes an annular slide block 4031 disposed inside the fixed plate 402, and an annular slide rail 4032 fitted on the inner circumference of the annular slide block 4031; a first grinding wheel 4033 is disposed at the bottom of the annular slide rail 4032, and a conical groove 4034 is formed at the bottom of the first grinding wheel 4033, and a first grinding hole 4035 arranged in a circular pattern is formed inside the conical groove 4034; a feeding hole 4036 is formed at the middle position of the top of the first grinding wheel 4033, which cooperates with the first grinding wheel 4033, and a keyway 4037 is formed on the outer circumference of the feeding hole 4036, which cooperates with the key 4014. The second grinding component 404 includes an annular slider 4041 disposed on the top of the cross support 405; a second grinding wheel 4042 disposed on the top of the cross support 405, the bottom of the second grinding wheel 4042 having an annular groove 4043 that mates with the annular slider 4041; a conical protrusion 4044 disposed on the top of the second grinding wheel 4042 that mates with the conical groove 4034, the top of the conical protrusion 4044 having second grinding holes 4045 arranged in a circular pattern; and a guide hole 4046 disposed on the outer circumferential wall of the second grinding wheel 4042 that mates with the second grinding holes 4045. The slope of the conical groove 4034 is greater than the slope of the conical protrusion 4044. This allows for progressively finer grinding of the material, effectively improving the fineness of the slurry.

[0024] The specific working principle of the grinding assembly 4 is as follows: When it is necessary to grind the material, the material flows through the feeding hopper 8 to the feeding pipe 2 and is transported to the grinding assembly 4. Since the diameter of the feeding pipe 2 is smaller than the diameter of the sleeve 4012, the material can smoothly pass through the sleeve 4012 and enter the discharge hole 4036 of the first grinding component 403. After the servo motor 4011 of the first driving component 401 is started, it drives the driving gear 4016 to rotate through the rotating shaft 4017. The driving gear 4016 meshes with the driven gear 4015, so that the sleeve 4012 rotates stably on the fixed plate 402 with the help of the bearing 4013. The key 4014 at the bottom of the sleeve 4012 cooperates with the keyway 4037 of the first grinding wheel 4033, driving the first grinding wheel 4033 to rotate along the annular slide rail 4032 in the annular slide block 4031. Simultaneously, the second driving component 406 drives the second grinding wheel 4042 to rotate along the annular slider 4041 at the top of the cross bracket 405 using the same principle, and the two rotate in opposite directions. The material falls from the feed hole 4036 into the space between the conical groove 4034 and the conical protrusion 4044. Utilizing the gradual grinding gap formed by the slope difference between the two, the material is repeatedly ground and refined through the first grinding hole 4035 and the second grinding hole 4045 during the relative rotation of the first grinding wheel 4033 and the second grinding wheel 4042, and finally discharged through the guide hole 4046. In one embodiment, the buffer assembly 3 includes a plurality of circumferentially arranged support columns 301 disposed on the outer circumference of the feed pipe 2, and the other end of each support column 301 is connected to a buffer cone 302. This reduces wear, deformation, or cracking of the feed pipe 2 after long-term use.

[0025] The specific working principle of the buffer component 3 is as follows: When the material flows at high speed in the feed pipe 2 under the action of gravity or conveying pressure, the buffer component 3 achieves the buffering function of the material through the synergistic action of the support column 301 and the buffer cone 302.

[0026] In one embodiment, the work box 1 described above has a control panel 9 on one side. This allows users to conveniently monitor and control the operating status of the equipment in real time.

[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0028] like Figures 1-9 As shown, in practical applications, the control panel 9 is electrically connected to two sets of servo motors 4011 in sequence.

[0029] First, the staff puts the material to be ground into the feed hopper 8. As the material flows along the feed pipe 2 to the grinding assembly 4, it first passes through the buffer assembly 3 for precise buffering. Then the material enters the grinding assembly 4 and falls through the sleeve 4012 into the discharge hole 4036 of the first grinding wheel 4033. Driven by the dual drive components, the conical structures of the first grinding wheel 4033 and the second grinding wheel 4042 rotate in opposite directions, repeatedly grinding the material using the gradual gap formed by the slope difference and the grinding holes. The refined bait is discharged through the guide hole 4046 and finally collected in the collection box 6 by the collection hopper 5.

[0030] The specific working principles of the buffer assembly 3 and the grinding assembly 4 are as described above.

[0031] In summary, by utilizing the above-mentioned technical solution of this utility model, the efficient optimization of material conveying and processing is achieved through the synergistic effect of the buffer component 3 and the grinding component 4. Specifically, the buffer component 3 provides precise and efficient buffering of the material conveyed by the feeding pipe 2. Simultaneously, the grinding component 4 employs a dual-drive forward and reverse rotation structure, precisely driving the relative motion of the conical structures of the first grinding component 403 and the second grinding component 404. The slope difference between the conical groove 4034 and the conical protrusion 4044 forms a gradual grinding gap. Combined with the circumferentially arranged grinding holes to increase the contact area, the shearing and grinding forces generated by the forward and reverse rotation drive achieve efficient and refined grinding of the material, effectively improving grinding efficiency and the quality of the finished slurry, thus meeting the fine requirements of bait processing. This invention, by incorporating a buffer component 3, allows the buffer cone 302 to directly absorb the impact force of materials when they are conveyed at high speed from the feeding pipe 2. Its conical structure disperses kinetic energy, preventing materials from directly impacting the inner wall of the feeding pipe due to gravity or conveying pressure. This reduces wear, deformation, or cracking of the feeding pipe 2 after long-term use, extending its service life. The invention also incorporates a grinding component 4, enabling efficient and refined grinding of the materials conveyed by the feeding pipe 2. The forward and reverse rotation drive structure of the first drive component 401 and the second drive component 406 drives the conical structures of the first grinding component 403 and the second grinding component 404 to rotate in both directions. The gradual grinding gap formed by the slope difference between the conical groove 4034 and the conical protrusion 4044 allows for progressively finer grinding of the materials, effectively improving the fineness of the slurry. Simultaneously, the circumferential arrangement of the first grinding hole 4035 and the second grinding hole 4045 increases the material grinding contact area, further improving grinding efficiency in conjunction with the relative motion generated by the forward and reverse rotation drive.
