[0053] S3. Assemble the support components of the functional components in the portion of the top cover that passes through the power cavity;

[0056] S6, driving the scraper to move along the annular material channel through the transmission mechanism, thereby driving the crayfish to move;

[0057] S7. During the transfer of crayfish, the functional component performs adaptive processing on the crayfish.

[0058] The crayfish metering and conveying mechanism, frying production line and application method of the present invention have the following beneficial effects compared with the prior art:

[0059] (1) By setting up an annular material channel and a weighing mechanism, when the transmission mechanism drives the scraper to transport crayfish, not only can the live or fried crayfish be weighed, but the volume of the device is also reduced; in addition, the transmission mechanism is installed in the power cavity inside the annular material channel, and the top cover also penetrates the power cavity. The part of the top cover penetrating the power cavity is used to install supporting components such as electrical cabinets and pumps, so that the space of the annular conveying mechanism is fully utilized, and the space occupation is further reduced on the basis of the original small footprint; and the part of the top cover penetrating the power cavity is a through-type structure, so that the supporting components can be inspected and repaired from two directions, ensuring the convenience of maintenance and facilitating electrical connection;

[0060] (2) In the metering and conveying mechanism, the transmission mechanism is a sprocket transmission mechanism, and the top cover is supported by the transmission shaft of the transmission mechanism, without the need for other fixing components. This not only achieves the covering of the power chamber, but also simplifies the assembly structure of the top cover, and also makes the top cover easy to disassemble for maintenance work;

[0061] (3) In the top cover, the power cavity is covered by a cover plate, and the inner cylinder penetrates the power cavity. A support is arranged around the inner cylinder for structural reinforcement. At the same time, the penetration structure also realizes the radial limit of the cover plate relative to the transmission shaft, so as to ensure the stability of the installation structure and improve the overall structural strength. At the same time, a partition is arranged at the lower end of the support, so as to facilitate the mounting of the support component, which not only increases the volume of the support component, but also ensures the convenience of maintenance;

[0062] (4) By arranging a rotating support in the conveying mechanism for installing the three-axis displacement mechanism and the guide rail, it can be used to install functional components to process crayfish; at the same time, the three-axis displacement mechanism and the guide rail can be conveniently rotated by the rotating support so that the three-axis displacement mechanism and the guide rail can be separated from the top cover, which is convenient for the inspection and cleaning of the conveying mechanism and will not interfere with the opening of the top cover; at the same time, in addition to being used to install functional components, the guide rail also supports the displacement of the three-axis displacement mechanism, which can ensure the stability of the adjustment structure;

[0063] (5) When limiting the three-axis displacement mechanism and the guide rail, the guide rail is connected to the top cover by bolts, and the three-axis displacement mechanism is connected to the guide rail by screws, thereby improving the convenience of fixing the three-axis displacement mechanism and the guide rail, and ensuring the relative position of the three-axis displacement mechanism and the guide rail;

[0064] (6) By setting up a second flexible plate with a mesh plate structure and a vibration motor, when the crayfish are dispersed by the vibration motor, oil, water or debris attached to the crayfish can be removed, so that the produced crayfish meet the standards, and it is also convenient to perform machine vision inspection through a camera.

DETAILED DESCRIPTION

[0077] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0078] like Figures 1 to 10 As shown, the crayfish metering and conveying mechanism of the present invention includes a base 1, a scraper 2, a transmission mechanism 3, a top cover 4, a weighing mechanism 5, a rotating support 6, a three-axis displacement mechanism 7, a guide rail 8, a functional component 9, a second flexible plate 10 and a vibration motor 1010;

[0079] The frying production line of the present invention comprises the above-mentioned crayfish metering and conveying mechanism, and further comprises an input conveying mechanism 100, an output conveying mechanism 200 and a frying machine 300.

[0080] like Figure 1 , Figure 8 and Fig. 9 As shown, the base 1 is provided with an annular channel 101, and the top of the annular channel 101 is open; a power chamber 102 is provided inside the annular channel 101, and the top of the power chamber 102 is open, wherein a plurality of scrapers 2 are provided in the annular channel 101; a transmission mechanism 3 is provided in the power chamber 102, and the transmission mechanism 3 is used to drive the scrapers 2 to move along the annular channel 101;

[0081] As in the above structure, the annular channel 101 is used to receive the crayfish, and then the transmission mechanism 3 drives the scraper 2 to move in the annular channel 101 to realize the transportation of the crayfish. In this process, since the top of the annular channel 101 is open, it is convenient to perform manual screening, automatic screening, cooling, air drying and other processes on the crayfish;

[0082] At the same time, since the power chamber 102 is located inside the annular channel 101, the mechanism has the advantage of a compact structure and reduces the floor space.

[0083] like Figures 3 to 6 As shown, the top cover 4 blocks the top of the power chamber 102, a portion of the top cover 4 penetrates the power chamber 102, and the portion of the top cover 4 that penetrates the power chamber 102 is a through structure;

[0084] As in the above structure, the top cover 4 is used to shield the power chamber 102 to achieve the function of safety protection. At the same time, the top cover 4 also partially passes through the power chamber 102, and the part passing through the power chamber 102 is set as a through structure, so that in this part, it can be used to install support components, such as industrial control components for installing screening, air drying and other processing components; this reduces the occupied area of ​​support components such as electrical cabinets and air pumps in this mechanism, making the structure of this mechanism more compact; at the same time, the through structure also facilitates electrical connection and maintenance work between components;

[0085] The weighing mechanism 5 is arranged in the annular material channel 101 and is used for weighing and measuring the crayfish;

[0086] like Figure 4 and Figure 5 As shown, specifically, the weighing mechanism 5 includes a first flexible plate 51 and an electronic scale 52, wherein the first flexible plate 51 is a component of the bottom surface of the base 1 to support the crayfish being transported; the electronic scale 52 is arranged on the outside of the annular material channel 101, and the electronic scale 52 is connected to the base 1 and corresponds to the first flexible plate 51;

[0087] As in the above structure, the first flexible plate 51 is used as a bottom component of the base 1. When the scraper 2 drives the crayfish to move, the crayfish will be transferred to the first flexible plate 51. At this time, the weight is transferred to the electronic scale 52, and the electronic scale 52 can be used for weighing and measurement.

[0088] The design of the metering and conveying structure can be used to weigh and measure living crayfish as well as fried crayfish, and is not limited by the state of the crayfish.

[0089] like Figure 3 and Fig. 9As shown, the base 1 includes a bottom plate 11, an inner ring plate 12, an outer ring plate 13 and a support plate 14, wherein the bottom plate 11 is an annular plate structure, the inner ring plate 12 and the outer ring plate 13 are relatively arranged on the inner and outer sides of the bottom plate 11 to form an annular material channel 101, and the inner side of the inner ring plate 12 is a power cavity 102; two support plates 14 are relatively arranged in the power cavity 102 to support the transmission mechanism 3; a through hole 103 is provided between the two support plates 14, and a part of the top cover 4 passes through the through hole 103;

[0090] As described above, the base 1 forms an annular material channel 101 and a power chamber 102 through the bottom plate 11, the inner ring plate 12 and the outer ring plate 13, and a through hole 103 is formed by arranging a support plate 14 in the power chamber 102;

[0091] During specific assembly, the transmission mechanism 3 is installed on the support plate 14 to drive the scraper 2 to move;

[0092] Furthermore, the top cover 4 will pass through the power cavity 102 and the through hole 103, so that the top cover 4 can be positioned relative to the base 1 to ensure the convenience of assembly and the structural stability after assembly.

[0093] like Figure 8 and Fig. 9 As shown, the transmission mechanism 3 includes a transmission shaft 31, a motor 32, a sprocket 33, a chain 34, a support seat 35 and a plane bearing 36, wherein one transmission shaft 31 is provided on each of the two support plates 14, and the transmission shaft 31 is a stepped shaft; the motor 32 is provided on the outer side of the support plate 14, and the main shaft of the motor 32 is connected to the small diameter end of the transmission shaft 31; one sprocket 33 is provided on each of the two transmission shafts 31, and the two sprockets 33 are meshed with the chain 34; the top cover 4 is supported by the transmission shaft 31, so that a gap 401 is left between the top cover 4 and the inner ring plate 12, and the scraper 2 passes through the gap 401 to connect the transmission mechanism 3;

[0094] As in the above structure, when the transmission mechanism 3 is in motion, the motor 32 drives one of the transmission shafts 31 and the sprocket 33 to rotate, and then the chain 34 drives the other transmission shaft 31 and the sprocket 33 to rotate. With the movement of the chain 34, the scraper 2 moves in the annular channel 101, thereby realizing the transportation of crayfish;

[0095] Specifically, in this structure, the transmission shaft 31 supports the top cover 4. When assembling, a bearing support can be provided on the top cover 4 and the support plate 14, and the end of the transmission shaft 31 is inserted into the bearing support, thereby ensuring the support of the top cover 4 by the transmission shaft 31 and the assembly stability of the transmission shaft 31, and will not interfere with the rotation of the transmission shaft 31.

[0096] When the top cover 4 is buckled onto the power chamber 102 , a gap 401 is left between it and the inner ring plate 12 of the base 1 to leave an assembly space for the chain 34 of the transmission mechanism 3 to be connected to the scraper 2 .

[0097] like Figure 8 As shown, the support seat 35 is disposed on the support plate 14 and surrounds the transmission shaft 31; the plane bearing 36 is sleeved on the transmission shaft 31, one side of the plane bearing 36 abuts against the stepped surface of the transmission shaft 31, and the other side abuts against the support seat 35;

[0098] Specifically, the shaft hole of the plane bearing 36 does not contact the transmission shaft 31 to reduce friction;

[0099] As in the above structure, after the top cover 4 is installed, since the top cover 4 also needs to be provided with a support assembly, it has a large weight. At this time, in order to ensure the assembly stability of the transmission shaft 31, the transmission shaft 31 is set as a stepped shaft structure, and a support seat 35 is installed on the support plate 14, and the support seat 35 is supported by the stepped surface of the transmission shaft 31 through the plane bearing 36, so as to share the force transmitted from the transmission shaft 31 to the support plate 14, so that the support plate 14 has a larger force-bearing area, thereby ensuring the stability of the structure;

[0100] Specifically, in this structure, the top cover 4 relies on its own weight to achieve axial positioning relative to the transmission shaft 31, and relies on its portion passing through the power chamber 102 to achieve radial positioning relative to the transmission shaft 31; this simplifies the assembly structure of the top cover 4 and also makes it easy to disassemble the top cover 4 for maintenance work;

[0101] Such as 8 and Fig. 9 As shown, the top cover 4 includes a cover plate 41, an inner cylinder 42, a support column 43 and a bottom plate 44, wherein the cover plate 41 is supported on the transmission shaft 31, and the side edge of the cover plate 41 extends toward the inner ring plate 12 to form a gap 401 between the cover plate 41 and the inner ring plate 12;

[0102] As in the above structure, the side of the cover plate 41 extends toward the inner ring plate 12 to form a gap 401 for connecting the transmission mechanism 3 and the scraper 2; this can ensure the closure of the power chamber 102 as much as possible to reduce the possibility of foreign matter entering;

[0103] The inner cylinder 42 is disposed in the middle of the cover plate 41 and passes through the through hole 103 ; the support column 43 is disposed on the side of the inner cylinder 42 and passes through the through hole 103 , and the support column 43 abuts against the side of the support plate 14 ;

[0104] In this structure, the top cover 4 penetrates the part of the power chamber 102, which is the inner tube 42 and the support 43, and also penetrates the through hole 103, so that the middle part of the base 1 is a vertical through structure, which is convenient for assembling support components and performing maintenance work;

[0105] In this structure, in order to ensure the stability of the inner tube 42, a support 43 is provided on its side for structural reinforcement, and the support 43 abuts against the side of the support plate 14, so that the structural stability of the top cover 4 relative to the base 1 can be ensured, and the positioning during assembly is also convenient;

[0106] The bottom plate 44 is disposed on one end of the support 43 that passes through the through hole 103, and the bottom plate 44 is spaced apart from the inner cylinder 42 to form an open structure;

[0107] Furthermore, a bottom plate 44 is provided on the bottom end of the support 43, so that the above-mentioned support components can be installed through the bottom plate 44, and there is a gap between the bottom plate 44 and the inner tube 42, so that the support components can be exposed, thereby facilitating maintenance.

[0108] In some embodiments, support legs are provided on the bottom surface of the base 1 and the bottom surface of the bottom plate 44, and both are in direct contact with the bottom surface to achieve stable support, which can reduce the load on the transmission shaft 31; in this way, the transmission shaft 31 is positioned at one end by the base 1 of the fixed structure, and the other end is positioned by the removable top cover 4.

[0109] Furthermore, the vacant position on the top surface of the top cover 4 can also be used to install support components.

[0110] like Figure 1 and Figure 2 As shown, a plurality of rotating supports 6 are provided on the base 1; a plurality of three-axis displacement mechanisms 7 and guide rails 8 are provided, and one end of the three-axis displacement mechanisms 7 and guide rails 8 are rotatably connected to the rotating support 6, and one end of each is overlapped on the top cover 4; the guide rail 8 is an arc-shaped plate structure for supporting the rotation of the three-axis displacement mechanism 7; the functional components 9 are provided on the three-axis displacement mechanism 7 and the guide rails 8, and the functional components 9 are one or more of a camera, a vacuum suction pipe, an air knife, a spray pipe and a spray component;

[0111] As in the above structure, the three-axis displacement mechanism 7 and the guide rail 8 are used to install the functional component 9, and the guide rail 8 is also used to adjust the position of the three-axis displacement mechanism 7;

[0112] Specifically, when used, the action end of the three-axis displacement mechanism 7 and the side of the guide rail 8 are used to install the functional component 9. The functional component 9 that needs displacement adjustment is installed on the active end of the three-axis displacement mechanism 7, while the functional component 9 that does not need displacement adjustment is installed on the side of the guide rail 8.

[0113] Since one end of the three-axis displacement mechanism 7 and the guide rail 8 is connected to the base 1 through the rotating support 6, the three-axis displacement mechanism 7 and the guide rail 8 can rotate to selectively overlap the top cover 4, thereby crossing the annular material channel 101, and then performing related process processing through the functional component 9;

[0114] Specifically, the guide rail 8 is set to an arc-shaped structure, and can be rotated to the running track of the three-axis displacement mechanism 7 overlapping one end of the top cover 4. In this way, when adjusting, the three-axis displacement mechanism 7 can be adjusted first, so that the end of the three-axis displacement mechanism 7 slides on the guide rail 8 to separate from the top cover 4 until it is completely placed on the base 1, and then the guide rail 8 is rotated to separate the guide rail 8 from the top cover 4; this structure can prevent the three-axis displacement mechanism 7 from being suspended and stressed, thereby avoiding damage to the rotating support 6 and the three-axis displacement mechanism 7, and can also ensure the accuracy of the three-axis displacement mechanism 7;

[0115] The three-axis displacement mechanism 7 may be provided with a moving wheel on the end surface, and the moving wheel cooperates with the guide rail 8 to move; or a slider may be provided on the end surface of the three-axis displacement mechanism 7 to cooperate with the guide rail 8;

[0116] In this structure, the guide rail 8 is used for both the mobile support of the three-axis displacement mechanism 7 and the installation of the functional component 9, thus achieving full utilization.

[0117] The setting of this adjustable structure can prevent the three-axis displacement mechanism 7 and the guide rail 8 from interfering with the cleaning of the annular material channel 101 and the disassembly and maintenance of the top cover 4, thereby improving the convenience of application; after completing the relevant cleaning and maintenance work, the three-axis displacement mechanism 7 and the guide rail 8 are rotated to overlap the top cover 4 and lock it.

[0118] The functional components carried by the three-axis displacement mechanism 7 and the guide rail 8 include but are not limited to: one or more of a camera, a vacuum suction tube, an air knife, a spray pipe and a spray component, so that photo detection, vacuum suction and screening, air supply and drying, spray cleaning and medium spraying can be realized, wherein photo detection and vacuum suction and screening can realize automatic detection and selection of crayfish, while air supply and drying can realize drying of crayfish, spray cleaning is used for cleaning of crayfish, and medium spraying is for spraying of treatment liquids such as cleaning agents; thereby, the device can be applied to the metering and transportation before and after frying of crayfish and related processing work;

[0119] Specifically, the camera is an industrial camera used for photo comparison detection;

[0120] Specifically, the vacuum pipette is arranged on the three-axis displacement mechanism 7, so that the three-axis displacement mechanism 7 can drive the vacuum pipette to move to achieve position adjustment.

[0121] like Figure 2As shown, the guide rail 8 includes a limiting section 81, a flat section 82 and a screw 83, wherein the cross section of the limiting section 81 is a U-shaped structure, which is used for the end limiting of the three-axis displacement mechanism 7 when rotating; a flat section 82 is provided at each end of the limiting section 81, wherein one flat section 82 is connected to the rotating support 6; the screw 83 is provided on the limiting section 81 close to the other flat section 82, and the flat section 82 close to the screw 83 is fixed to the top cover 4 by bolt locking; the screw 83 is fixed to the end of the three-axis displacement mechanism 7 by nuts;

[0122] As in the above structure, the guide rail 8 has a limiting section 81 in the middle and flat sections 82 at both ends. The guide rail 8 is slidably matched with the three-axis displacement mechanism 7 through the limiting section 81 in the middle. After the three-axis displacement mechanism 7 is adjusted into place, the guide rail 8 needs to be adjusted. If the guide rail 8 is only provided with the limiting section 81 with a U-shaped cross section, the limiting section 81 will interfere with the moving wheel or the slider on the three-axis displacement mechanism 7 when the guide rail 8 is rotated.

[0123] After the flat plate section 82 is set, the movable end of the three-axis displacement mechanism 7 can be moved to the flat plate section 82 connected to the rotating support 6. At this time, when the guide rail 8 is rotated, there will be no interference problem, so that the rotation adjustment action of the guide rail 8 can be realized.

[0124] When fixing the three-axis displacement mechanism 7 and the guide rail 8 to the top cover 4, the other flat plate section 82 of the guide rail 8 is fixedly connected to the top cover 4 by bolts, and then the end of the three-axis displacement mechanism 7 is engaged with the screw 83 on the guide rail 8 and locked by a nut, so that the three-axis displacement mechanism 7, the guide rail 8 and the top cover 4 are relatively fixed to ensure the stability of the structure during application;

[0125] Specifically, a screw rod may also be provided on the top cover 4, and a U-shaped slot may be provided on the flat plate section 82, so that when the guide rail 8 is rotated, the U-shaped slot may be snapped onto the screw rod; this structure requires attention to the opening direction of the U-shaped slot to avoid interfering with the rotation of the guide rail 8.

[0126] like Figure 4 , Figure 6 and Figure 7 As shown, the second flexible plate 10 is a component of the bottom surface of the base 1 to support the crayfish being transported, and the second flexible plate 10 is a mesh plate; the vibration motor 1010 is connected to the base 1 and corresponds to the second flexible plate 10;

[0127] As in the above structure, when the scraper 2 pushes the crayfish for transportation, accumulation is inevitable, which will affect the camera in the functional component 9 to take pictures of the crayfish, so the crayfish need to be dispersed;

[0128] Specifically, when the crayfish gather on the second flexible board 10, the corresponding camera will be synchronized. At this time, the vibration of the vibration motor 1010 can be used to disperse the crayfish so that the crayfish are spread out, thereby facilitating photo detection.

[0129] At the same time, the water or oil carried by the crayfish will also fall off quickly and seep down through the mesh-shaped second flexible plate 10. A liquid collecting measure may be provided on the lower side of the second flexible plate 10 to prevent the water or oil from dispersing.

[0130] Here, the mesh size of the second flexible plate 10 needs to be controlled to be extremely small to avoid the lobster from getting stuck.

[0131] like Fig.10 As shown, the input conveying mechanism 100 is arranged on one side of the fryer 300, for inputting the crayfish into the fryer 300; the output conveying mechanism 200 is arranged on the other side of the fryer 300, for outputting the crayfish from the fryer 300; the crayfish metering and conveying mechanism is arranged at one end of the input conveying mechanism 100 away from the fryer 300, and / or at one end of the output conveying mechanism 200 away from the fryer 300; the crayfish metering and conveying mechanism located on the input side, the functional components 9 are a camera, a vacuum suction pipe, an air knife, a spray pipe and a spray component; the crayfish metering and conveying mechanism located on the output side, the functional components 9 are a camera, a vacuum suction pipe, an air knife and a spray component.

[0132] like Fig.10 As shown, the input conveying mechanism 100 is arranged at one side of the fryer 300, and is used to input the crayfish into the fryer 300; the output conveying mechanism 200 is arranged at the other side of the fryer 300, and is used to output the crayfish from the fryer 300; the crayfish metering and conveying mechanism is arranged at one end of the input conveying mechanism 100 away from the fryer 300, and / or at one end of the output conveying mechanism 200 away from the fryer 300; the crayfish metering and conveying mechanism located on the input side, the functional components 9 are a camera, a vacuum suction pipe, an air knife, a spray pipe and a spray component; the crayfish metering and conveying mechanism located on the output side, the functional components 9 are a camera, a vacuum suction pipe, an air knife and a spray component;

[0133] As in the above structure, when the frying process of crayfish is carried out, a metering and conveying mechanism can be first set up to convey and process the front end of the crayfish;

[0134] Specifically, it can be equipped with a camera, a vacuum pipe, an air knife, a spray pipe and a spray assembly to achieve front-end detection and screening of crayfish, cleaning and drying, and spraying of treatment liquid;

[0135] After the front-end processing, the crayfish is fed into the fryer 300 through the input conveyor mechanism 100 for frying, and then lifted and output through the output conveyor mechanism 200 and transferred to the metering conveyor mechanism at the rear end;

[0136] In the metering and conveying mechanism at the back end, the functional components are cameras, vacuum pipettes, air knives and spray components for secondary inspection and sorting, air cooling, and spraying of treatment liquids;

[0137] Specifically, the input conveying mechanism 100 and the output conveying mechanism 200 may adopt chain conveyors, which is conducive to draining water and oil.

[0138] like Figure 4 and Figure 6 As shown, a discharge port 104 may be provided on the bottom plate 11 of the base 1 to discharge the processed crayfish.
