Description

Technical Field

[0001] This invention relates to the field of aquatic product processing equipment technology, and more specifically, to a scallop shelling and cleaning integrated machine. Background Technology

[0002] As an important economic aquatic product, the shelling and cleaning processes of scallops are crucial to product quality and production efficiency. Currently, scallop shelling and cleaning mainly rely on manual labor, which suffers from low efficiency, high labor costs, and safety hazards, making it difficult to meet the needs of large-scale production.

[0003] In terms of automated processing, existing technologies are mainly polarized:

[0004] On the one hand, some large-scale assembly line processing plants use a combination of steam opening and vibration to separate the shell and meat. This method uses high-temperature steam to open the scallop shells and then vibration to separate the shell and meat. Although it is highly efficient, the high-temperature steam will seriously damage the scallop meat, resulting in a poor taste and loss of nutrients, thus reducing the economic added value of aquatic products.

[0005] On the other hand, some devices rely on visual recognition systems combined with sophisticated electronic control mechanisms to cut the adductor muscle of the scallop. These devices use visual recognition of the scallop's position and posture to control the cutting mechanism, precisely cutting the adductor muscle to open the shell. However, these devices are not only extremely complex in structure and expensive to manufacture, but also have low single-unit processing efficiency, making them difficult to widely adopt and promote.

[0006] Furthermore, existing scallop processing equipment generally suffers from limited functionality, only capable of opening and separating the scallops without the ability to count or weigh the output. The scallop meat, after being shelled and cleaned, still needs to be manually transferred to subsequent workstations for weighing and recording, causing a break in the production line and preventing fully automated closed-loop production. At the same time, existing equipment is mostly large industrial-grade machinery, requiring significant floor space and incurring high investment costs, while the market severely lacks compact equipment suitable for small and medium-sized applications.

[0007] In summary, there is an urgent need for a scallop shelling and cleaning machine that is structurally simple, cost-controllable, can perfectly preserve the meat quality, and is highly integrated. Summary of the Invention

[0008] The present invention aims to provide a scallop shelling and cleaning integrated machine with a simplified structure, controllable cost, and the ability to preserve the meat quality intact. This machine solves the problems of existing technologies, such as complex equipment structure, high cost, easy damage to meat quality, single function, inability to form an automated closed-loop production, and lack of equipment suitable for small and medium-sized application scenarios.

[0009] The technical solution adopted in this invention is as follows: a scallop shelling and cleaning integrated machine, including a frame and a feeding and positioning mechanism, a conveying mechanism, a guide groove, a cutting and shelling mechanism, a shell and meat separation mechanism, a cleaning and collection mechanism, and a drive unit installed on the frame;

[0010] The feeding and positioning mechanism includes a feeding hopper, the bottom of which is divided into multiple independent feeding channels. Each feeding channel is provided with a rotating indexing roller. Multiple grooves for accommodating a single scallop are distributed on the circumference of the rotating indexing roller. The multiple rotating indexing rollers are connected by a rotating shaft.

[0011] The conveying mechanism is located below the feeding and positioning mechanism. It includes a synchronous conveyor belt and multiple fixtures arrayed on the synchronous conveyor belt. The fixtures correspond to the unloading channel in number and arrangement. The running speed of the synchronous conveyor belt is matched with the rotation speed of the rotating indexing roller. Each fixture includes two clamping plates. One side of the two clamping plates is rotatably connected to a shaft installed on the synchronous conveyor belt. The adjacent sides of the two clamping plates are provided with arc-shaped receiving grooves adapted to the shape of scallops. When the two clamping plates are closed together, they clamp the scallops.

[0012] The guide trough is disposed between the feeding and positioning mechanism and the synchronous conveyor belt. The guide trough has a wide portion and a narrow portion connected to the wide portion along the conveying direction. The wide portion is located below the unloading channel.

[0013] The cutting and shell-opening mechanism is located in the narrow part of the guide groove. The cutting and shell-opening mechanism includes a saw blade shaft and multiple circular saw blades fixedly installed on the saw blade shaft at intervals. The multiple circular saw blades are arranged in a one-to-one correspondence with the multiple guide grooves.

[0014] The shell-meat separation mechanism is located behind the guide groove and on the movement path of the fixture after it moves out of the guide groove. The shell-meat separation mechanism includes a transverse rotating feeding shaft with multiple sets of rotating scrapers distributed on it. The position of the rotating scrapers corresponds to the position of the fixture after it moves out of the guide groove and unfolds.

[0015] A cleaning and collection mechanism is located behind the shell and meat separation mechanism. The cleaning and collection mechanism includes a collection plate located behind the rotating scraper for receiving scallop meat scraped out by the rotating scraper. A rinsing pipe is located above the collection plate for rinsing the scallop meat on the collection plate. A meat collection box is connected to the end of the collection plate.

[0016] The drive unit is connected to the rotating shaft, the synchronous conveyor belt, the saw blade shaft, and the rotating feeding shaft respectively, and is used to drive the rotating shaft to rotate, the synchronous conveyor belt to circulate, the saw blade shaft to rotate, and the rotating feeding shaft to rotate.

[0017] Furthermore, when the fixture moves with the synchronous conveyor belt, it first enters the wide part of the guide groove so that the two clamping plates open to an angle that facilitates the entry of the scallop. When the fixture enters the narrow part of the guide groove, the side wall of the narrow part presses the two clamping plates together to lock the scallop.

[0018] Furthermore, after the fixture is removed from the guide groove, the two clamping plates are flipped and unfolded to both sides.

[0019] Furthermore, the rotating scraper rotates under the drive of the rotating feeding shaft and penetrates into the cut scallop to scrape the scallop meat out of the scallop shell.

[0020] Furthermore, the synchronous conveyor belt is a ring conveyor belt, including two conveyor chains and multiple support plates. The two ends of the support plates are respectively connected to the conveyor chains on both sides. The fixtures are installed on the support plates, and the position and number of fixtures on each support plate correspond to the unloading channel.

[0021] Furthermore, a shell-splitting block is provided at the end of the narrow section of the guide groove. The shell-splitting block is prismatic and is arranged in a one-to-one correspondence with the circular saw blade. When the fixture moves the cut scallop to the shell-splitting block, the shell-splitting block is inserted into the cut gap of the scallop to push the two shells of the scallop apart to the sides.

[0022] Furthermore, it also includes a counting unit, which includes a photoelectric sensor disposed on the side of the synchronous conveyor belt. The detection end of the photoelectric sensor is opposite to the moving path of the fixture, and is used to detect the number of times the fixture row passes through the synchronous conveyor belt in order to count the number of scallops processed.

[0023] Furthermore, it also includes a weighing module, which is located below the meat collection box and is used to support the meat collection box and weigh the meat collection box and the scallop meat inside.

[0024] Furthermore, the cleaning and collection mechanism also includes an empty shell collection box, which is located below the end of the synchronous conveyor belt and is used to collect empty shells that fall off as the fixture flips.

[0025] Furthermore, the empty shell collection box is located below the meat collection box. Both the bottom plate of the meat collection box and the bottom plate of the empty shell collection box are provided with water filter holes. A filter water tank is also provided below the empty shell collection box. The filter water tank is connected to the rinsing pipe through a water pipe.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) This invention abandons the complex visual recognition system and precision electronically controlled cutting mechanism in the prior art, and adopts a purely mechanical cutting, shell splitting, and meat scraping action execution mechanism. By setting the speed matching of the rotating indexing roller and the synchronous conveyor belt, and with the wide and narrow structure of the guide groove, the automatic quantitative distribution and precise clamping of scallops are realized. By fixing multiple circular saw blades on the same saw blade shaft, the transmission structure of the cutting and shell splitting mechanism is simplified. The overall structure is simplified, which greatly reduces the manufacturing cost of the equipment and the difficulty of later maintenance, and is especially suitable for small and medium-sized application scenarios.

[0028] (2) The present invention uses mechanical cutting to replace the destructive steam shell opening and vibration separation. The shell is opened by precisely cutting the adductor muscle with a circular saw blade, avoiding the damage of high temperature steam to the scallop meat. The shell and meat separation mechanism uses a rotating scraper to mechanically scrape out the meat. While retaining the advantages of efficient processing of the production line, it ensures the integrity of the extracted scallop meat to the greatest extent, improves the product appearance and economic added value, and achieves the unity of high quality and high efficiency.

[0029] (3) This invention integrates multiple processes such as feeding and positioning, conveying, cutting and opening the shell, separating the shell and meat, cleaning and collecting, counting and weighing, realizing full automation from scallops in shell to clean meat output. By setting up photoelectric sensors to count the jig rows, the number of scallops processed is automatically counted; by setting up a weighing module to weigh the meat collection box and the scallop meat inside as a whole, the output is automatically measured. After the scallop meat is processed, accurate data is directly output, eliminating the tedious process of manual secondary transfer and weighing, and opening up the last link of full automation;

[0030] (4) The present invention sets up an empty shell collection box in the cleaning and collection mechanism to realize the automatic separation and collection of empty shells and scallop meat; by setting water filter holes on the bottom plate of the meat collection box and the empty shell collection box, and setting a filter water tank below the empty shell collection box, the filtered water is circulated to the rinsing pipe through the water pipe, realizing the recycling of rinsing water and effectively saving water resources.

[0031] (5) This invention realizes the fully automated operation of scallop shelling and cleaning. The single machine has high processing efficiency and can run continuously and stably. It greatly reduces the manual operation links and reduces labor costs. The whole system has a compact structure and a small footprint. It is not only suitable for small and medium-sized aquatic product processing enterprises, but can also be applied to household, micro aquatic product vendors and catering chain kitchens, etc., and has broad market application prospects.

Detailed Implementation

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1-8 As shown, this embodiment provides a scallop shelling and cleaning integrated machine, including a frame 1 and a feeding and positioning mechanism 2, a conveying mechanism 3, a guide groove 9, a shell cutting and opening mechanism 4, a shell and meat separation mechanism 5, a cleaning and collection mechanism 6, and a drive unit 7 installed on the frame 1.

[0043] like Figure 2 , Figure 3 As shown, the feeding and positioning mechanism 2 includes a feeding hopper 21, the bottom of which is divided into multiple independent feeding channels 22. Each feeding channel 22 is equipped with a rotating indexing roller 23. Multiple grooves 231 are distributed on the circumference of the rotating indexing roller 23. The shape of these grooves 231 matches the outline of a scallop, serving to accommodate a single scallop. The multiple rotating indexing rollers 23 are connected by a rotating shaft 24 to achieve synchronous rotation.

[0044] The conveying mechanism 3 is located below the feeding and positioning mechanism 2, and includes a synchronous conveyor belt and multiple fixtures 33 arrayed on the synchronous conveyor belt. Figure 4 , Figure 5 As shown, the synchronous conveyor belt is a ring conveyor belt, including two conveyor chains 31 and multiple support plates 32. Both ends of the support plates 32 are connected to the conveyor chains 31 on both sides, and fixtures 33 are mounted on the support plates 32. The position and number of fixtures 33 on each support plate 32 correspond to the material discharge channel 22. Figure 5 As shown, each fixture 33 includes two clamping plates 331. One side of each clamping plate 331 is rotatably connected to a shaft mounted on a support plate 32. Adjacent sides of each clamping plate 331 are provided with arc-shaped receiving grooves 332 adapted to the shape of a scallop. When the two clamping plates 331 are closed together, they can clamp the scallop. The running speed of the synchronous conveyor belt is matched with the rotational speed of the rotating indexing roller 23, ensuring that the scallop falls precisely into the fixture 33 when it exits the feeding channel 22.

[0045] The guide groove 9 is located between the feeding and positioning mechanism 2 and the synchronous conveyor belt. Figure 6As shown, the guide trough 9 has a wide portion 91 and a narrow portion 92 connected to the wide portion 91 along the conveying direction, wherein the wide portion 91 is located directly below the unloading channel 22. When the fixture 33 moves with the synchronous conveyor belt, it first enters the wide portion 91 of the guide trough 9. At the wide portion 91, the sidewall of the guide trough 9 constrains the two clamping plates 331 of the fixture 33, keeping the two clamping plates 331 open at an angle that facilitates the entry of the scallops. At this time, the scallops fall out from the unloading channel 22 and smoothly enter between the two clamping plates 331. When the fixture 33 continues to move forward and enters the narrow portion 92 of the guide trough 9, the sidewall of the narrow portion 92 further presses the two clamping plates 331 together, thereby firmly locking the scallops between the clamping plates.

[0046] The shell-opening mechanism 4 is located at the narrow portion 92 of the guide groove 9. This mechanism includes a saw blade shaft 42 and multiple circular saw blades 41 fixedly mounted on the saw blade shaft 42 at intervals. Each of the multiple circular saw blades 41 corresponds one-to-one with a different guide groove 9. When the scallop is locked into the narrow portion 92 of the guide groove 9 by the fixture 33, the high-speed rotating circular saw blades 41 precisely cut the scallop's adductor muscle, achieving automated shell opening.

[0047] A shell-separating block 93 is provided at the end of the narrow section 92 of the guide groove 9. The shell-separating block 93 is prismatic and is arranged one-to-one with the circular saw blade 41. When the jig 33 moves the cut scallop to the shell-separating block 93, the shell-separating block 93 is inserted into the cut slit of the scallop. The gradually expanding shape of its prismatic structure gradually opens the two shells of the scallop to both sides, creating conditions for the subsequent separation of shell and meat.

[0048] As the jig 33 continues to move forward and moves out of the guide groove 9, the two clamps 331 are freed from the side wall constraints of the narrow part 92 of the guide groove and unfold to the sides under their own gravity. At this time, the cut scallops are respectively in the arc-shaped receiving grooves 332 of the two clamps 331.

[0049] The shell-meat separation mechanism 5 is located behind the guide groove 9 and on the movement path of the fixture 33 after it has moved out of the guide groove 9. Figure 7 , Figure 8 As shown, the mechanism includes a transverse rotating feeding shaft 51, on which multiple sets of rotating scrapers 52 are distributed. The positions of the rotating scrapers 52 correspond to the positions of the fixture 33 after it is unfolded. The rotating feeding shaft 51 drives the rotating scrapers 52 to rotate, and the rotating scrapers 52 penetrate into the cut scallop, scraping the scallop meat completely out of the scallop shell through the mechanical force of rotation.

[0050] The cleaning and collection mechanism 6 is located behind the shell-meat separation mechanism 5. This mechanism includes a collection plate 61, a rinsing pipe 62, a meat collection box 63, and an empty shell collection box 64. The collection plate 61 is located behind the rotating scraper 52 and is used to collect the scallop meat scraped out by the rotating scraper 52. The rinsing pipe 62 is located above the collection plate 61 and is used to rinse the scallop meat on the collection plate 61. The end of the collection plate 61 is connected to a slide and extends downwards at an angle to the meat collection box 63, where the rinsed scallop meat falls into the meat collection box 63.

[0051] An empty shell collection box 64 is installed below the end of the synchronous conveyor belt. When the fixture 33 moves to the end of the synchronous conveyor belt and flips as the conveyor chain 31 turns, the empty shells remaining on the clamping plate fall off under gravity and are collected by the empty shell collection box 64. The empty shell collection box 64 is located below the meat collection box 63. Both the bottom plate of the meat collection box 63 and the bottom plate of the empty shell collection box 64 are provided with water filter holes. A filter water tank 65 is also provided below the empty shell collection box 64. The filter water tank 65 is connected to the rinsing pipe 62 through a water pipe 66 to realize the recycling of rinsing water.

[0052] The invention also includes a counting unit and a weighing module. The counting unit includes a photoelectric sensor 8 mounted on the side of the frame 1. Specifically, the photoelectric sensor 8 is mounted on the side of the synchronous conveyor belt, and its detection end corresponds to the position where the fixture 33 has moved out of the guide groove 9 but has not yet flipped over. When the fixture 33 passes through this position, it blocks the light path, and the photoelectric sensor 8 outputs a detection signal. By counting the number of times the fixture row passes through, the number of scallops processed is automatically counted. The weighing module is located below the meat collection box 63, used to support the meat collection box 63 and to weigh the meat collection box 63 and the scallop meat inside it as a whole.

[0053] The drive unit 7 is connected to the rotating shaft 24, the synchronous conveyor belt, the saw blade shaft 42, and the rotating feeding shaft 51 respectively, and is used to drive the rotating shaft 24 to rotate, the synchronous conveyor belt to circulate, the saw blade shaft 42 to rotate, and the rotating feeding shaft 51 to rotate, providing power for the automated operation of the whole machine.

[0054] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the inventive concept of the present invention, and all such modifications or additions should fall within the protection scope of the present invention.
