Description

Technical Field

[0001] The present invention relates to the field of squid grading and sorting, and in particular to an automatic squid sorting system carried by an ocean squid fishing vessel. Background Art

[0002] As the squid fishing industry expands, challenges hindering its high-quality development are becoming increasingly prominent. First, in recent years, distant-water fishing vessels have struggled to recruit workers, facing a severe labor shortage. Furthermore, rising wages have put pressure on distant-water fishing companies. Second, offshore squid grading, sorting, and weighing are labor-intensive and demanding. Third, the rapid development of downstream industries like processing, warehousing, and logistics has heightened the demands on squid grading and sorting during the primary fishing process, requiring vessels to perform more precise squid grading.

[0003] However, due to the special working environment and complex working conditions at sea, there has been little research on ship-borne grading and sorting equipment, and there are few practical application cases. In particular, the grading and sorting of mollusks such as squid is difficult and is still mainly done manually. Semi-automatic and automated sorting equipment has not been developed and applied accordingly, which has restricted the high-quality development of the industry. With the advent of the intelligent era, through the research and development and improvement of semi-automatic and automated equipment, the development of ship-borne grading and sorting equipment suitable for squid fishing vessels will gradually reduce the number of workers on fishing vessels, reduce labor costs, reduce the workload of crew members, and improve work efficiency. This is of great significance to ensuring the high-quality and sustainable development of the squid fishing industry. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic squid sorting system for ocean squid fishing vessels, which can automatically grade and sort squids according to weight, thereby reducing the number of workers on fishing vessels, lowering labor costs and improving work efficiency.

[0005] The technical solution of the present invention is:

[0006] An automatic squid sorting system for a deep-sea squid fishing vessel, comprising:

[0007] Feeding conveyor belt;

[0008] The pull-distance conveyor belt has an input end connected to the output end of the feeding conveyor belt, and the conveying speed of the pull-distance conveyor belt is greater than the conveying speed of the feeding conveyor belt;

[0009] The weighing conveyor belt has its input end connected to the output end of the pull-distance conveyor belt;

[0010] The input end of the grading conveyor belt is connected to the output end of the weighing conveyor belt;

[0011] a plurality of frame conveyor belts sequentially distributed along the conveying direction of the graded conveyor belt; and

[0012] The several grading push-out devices corresponding to the frame loading conveyor belt each include a push plate located above the grading conveyor belt and a translation mechanism for driving the push plate to move, and the grading push-out device pushes the squid conveyed on the grading conveyor belt onto the corresponding frame loading conveyor belt.

[0013] The squid is conveyed backward in sequence through the feeding conveyor belt, and when the squid is conveyed onto the distance pulling conveyor belt, the conveying speed of the distance pulling conveyor belt is greater than that of the feeding conveyor belt, so that the distance between the squid can be effectively increased after the squid passes through the distance pulling conveyor belt and enters the weighing conveyor belt.

[0014] Then, the squid is conveyed onto the weighing conveyor belt, the squid on the weighing conveyor belt is weighed, and the squid is divided into several grades according to the weight, and each weight grade corresponds to a frame loading conveyor belt.

[0015] Then, the squid is conveyed onto the grading conveyor belt, and the distance between the squid is effectively increased after the squid passes through the distance pulling conveyor belt. When the grading conveyor belt conveys the squid of a certain weight grade to the position of the corresponding frame loading conveyor belt, the grading push-out device corresponding to the frame loading conveyor belt works to push the squid of a certain weight grade conveyed on the grading conveyor belt onto the corresponding frame loading conveyor belt, so as to avoid pushing two or more squid at a time, thereby realizing automatic grading and sorting of the squid according to the weight, reducing the labor of the fishing boat, reducing the labor cost, and improving the work efficiency.

[0016] As a preferred, it further includes several storage frames corresponding to the frame loading conveyor belt one by one, and the storage frame is located below the output end of the corresponding frame loading conveyor belt. In this way, the squid conveyed to the frame loading conveyor belt according to the weight can be input into the corresponding storage frame.

[0017] As a preferred, it further includes a refrigerated conveyor belt for conveying the storage frame into the refrigeration compartment of the squid jigging ship, and the refrigerated conveyor belt is parallel to the grading conveyor belt, and the frame loading conveyor belt is located between the refrigerated conveyor belt and the grading conveyor belt. In this way, when the squid in the storage frame reaches a certain amount, the storage frame can be input into the refrigeration compartment of the squid jigging ship through the refrigerated conveyor belt for refrigeration.

[0018] As a preferred, it further includes several inclined guide plates corresponding to the frame loading conveyor belt one by one, and the inclined guide plates are located above the corresponding frame loading conveyor belt and are distributed in an inclined manner. When the grading push-out device pushes the squid conveyed on the grading conveyor belt, the squid is input onto the corresponding frame loading conveyor belt through the inclined guide plates. In this way, after the squid is separated from the grading conveyor belt, it can be smoothly input onto the corresponding frame loading conveyor belt through the inclined guide plates.

[0019] Preferably, the conveying speed of the draw conveyor belt is twice that of the feeding conveyor belt. This ensures that the squids are spaced sufficiently apart after passing through the draw conveyor belt. When the grading and pushing-out device pushes squids of a certain weight grade conveyed on the grading conveyor belt onto the corresponding frame conveyor belt, it avoids pushing out two or more squids at once, thereby achieving automatic grading and sorting of the squids by weight.

[0020] Preferably, the push plate comprises:

[0021] A vertically distributed main push plate with a downward-facing vertical guide groove provided inside the main push plate;

[0022] The floating push plate is slidingly arranged in the vertical guide groove. The bottom end of the floating push plate is provided with a ball. The floating push plate moves downward along the vertical guide groove under the action of its own weight until the ball is supported on the upper surface of the grading conveyor belt. At this time, the distance between the bottom end of the floating push plate and the upper surface of the grading conveyor belt is less than 2 mm. Since squid is a mollusk, it has a large number of squid legs; and there is an inevitable gap between the push plate and the upper surface of the grading conveyor belt, and since the grading conveyor belt is in a conveying state (the position of the upper surface of the grading conveyor belt will fluctuate up and down in the conveying state), the gap is difficult to control; this makes it easy for the squid legs to be clamped between the push plate and the upper surface of the grading conveyor belt in the process of the push plate pushing the squid conveyed on the grading conveyor belt to the corresponding frame conveyor belt, resulting in the push plate being stuck and unable to push the squid to the corresponding frame conveyor belt, and causing squid legs and even squid body to be squeezed and damaged. In order to solve this problem, the push plate is improved in this solution. Specifically,

[0023] Since the main push plate is provided with a floating push plate that can move up and down, and the floating push plate moves downward along the vertical guide groove under the action of its own weight until the ball support is on the upper surface of the grading conveyor belt, at this time, the distance between the bottom end of the floating push plate and the upper surface of the grading conveyor belt is less than 2 mm; based on this, even if the grading conveyor belt is in the conveying state, the distance between the push plate and the upper surface of the grading conveyor belt can be ensured to be less than 2 mm, and the gap between the push plate and the grading conveyor belt can be effectively controlled to be maintained at a sufficiently small level, thereby effectively reducing the problem of the squid feet being clamped between the push plate and the upper surface of the grading conveyor belt, causing the push plate to be stuck and unable to push the squid onto the corresponding frame conveyor belt, and causing squid feet and even squid body to be squeezed and damaged.

[0024] Preferably, the graded ejection device further comprises:

[0025] A displacement sensor is provided on the floating push plate below the main push plate, and detects the distance between the floating push plate and the upper surface of the grading conveyor belt;

[0026] In the process that the grading push-out device pushes out the squid conveyed on the grading conveyor belt to the corresponding grading conveyor belt, when the displacement sensor detects that the distance between the displacement sensor and the upper surface of the grading conveyor belt exceeds the operation setting value, the translation mechanism drives the push plate to move back until the floating push plate moves downward and the ball is supported on the upper surface of the grading conveyor belt, and then the translation mechanism pushes out the push plate again. By controlling the gap between the push plate and the grading conveyor belt to be small enough, although the problem of squid feet being clamped between the push plate and the upper surface of the grading conveyor belt can be effectively reduced, a small amount of squid feet will still be clamped between the push plate and the upper surface of the grading conveyor belt. In order to further solve this problem, the grading push-out device and the push-out method are further improved, specifically,

[0027] In the process that the grading push-out device pushes out the squid conveyed on the grading conveyor belt to the corresponding grading conveyor belt, when the displacement sensor detects that the distance between the displacement sensor and the upper surface of the grading conveyor belt exceeds the operation setting value, the translation mechanism drives the push plate to move back until the floating push plate moves downward and the ball is supported on the upper surface of the grading conveyor belt, and then the translation mechanism pushes out the push plate again. By controlling the gap between the push plate and the upper surface of the grading conveyor belt to be small enough, although the problem of squid feet being clamped between the push plate and the upper surface of the grading conveyor belt can be effectively reduced, a small amount of squid feet will still be clamped between the push plate and the upper surface of the grading conveyor belt. In order to further solve this problem, the grading push-out device and the push-out method are further improved, specifically,

[0028] As a preferred, the grading push-out device further comprises:

[0029] The side baffle is hinged to one side of the push plate away from the input end of the grading conveyor belt;

[0030] The electromagnet is arranged on the push plate and close to the side baffle;

[0031] The elastic element is arranged on the push plate and close to the side baffle;

[0032] The electromagnet is powered off before the push plate is pushed out;

[0033] In the process that the translation mechanism pushes out the push plate, the electromagnet is powered on, and the side baffle is adsorbed and fixed on the electromagnet. In the process that the grading push-out device pushes out the squid conveyed on the grading conveying belt to the corresponding frame conveying belt; especially in the process that the squid foot is clamped between the push plate and the upper surface of the grading conveying belt, and the push plate moves back, in order to avoid that the squid on the grading conveying belt is conveyed backward and separated from the push plate, the side baffle is arranged on the side of the push plate away from the input end of the grading conveying belt, so that the push plate can push out the squid conveyed on the grading conveying belt to the corresponding frame conveying belt. However, in this way, before the push plate is pushed out, the squid may be blocked by the side baffle on a certain grading push-out device, so that the squid cannot be conveyed to the designated grading push-out device smoothly. In order to solve this problem, the grading push-out device is improved, and before the push plate is pushed out, the electromagnet is powered off. If the squid is blocked by the side baffle on a certain grading push-out device, the squid will overcome the force of the elastic element, make the side baffle rotate, and then continue to convey backward to the designated grading push-out device by overcoming the side baffle.

[0034] In the process that the translation mechanism pushes out the push plate, the electromagnet is powered on, and the side baffle is adsorbed and fixed on the electromagnet. In the process that the grading push-out device pushes out the squid conveyed on the grading conveying belt to the corresponding frame conveying belt; especially in the process that the squid foot is clamped between the push plate and the upper surface of the grading conveying belt, and the push plate moves back, in order to avoid that the squid on the grading conveying belt is conveyed backward and separated from the push plate, the side baffle is arranged on the side of the push plate away from the input end of the grading conveying belt, so that the push plate can push out the squid conveyed on the grading conveying belt to the corresponding frame conveying belt. However, in this way, before the push plate is pushed out, the squid may be blocked by the side baffle on a certain grading push-out device, so that the squid cannot be conveyed to the designated grading push-out device smoothly. In order to solve this problem, the grading push-out device is improved, and before the push plate is pushed out, the electromagnet is powered off. If the squid is blocked by the side baffle on a certain grading push-out device, the squid will overcome the force of the elastic element, make the side baffle rotate, and then continue to convey backward to the designated grading push-out device by overcoming the side baffle.

[0035] As preferred, the grading push-out device further comprises a limiting block, and the push plate abuts against the limiting block before the push plate is pushed out.

[0036] As preferred, the upper surfaces of the feeding conveying belt, the distance pulling conveying belt, the weighing conveying belt and the grading conveying belt are at the same height.

[0037] The beneficial effects of the present application are:

[0038] The squid is conveyed to the rear in turn through the feeding conveying belt. When the squid is conveyed to the distance conveying belt, the conveying speed of the distance conveying belt is greater than that of the feeding conveying belt. Thus, the distance between the squid can be effectively increased when the squid passes through the distance conveying belt and enters the weighing conveying belt. The squid is conveyed to the grading conveying belt. Since the distance between the squid is effectively increased after the squid passes through the distance conveying belt, when the grading conveying belt conveys the squid of a certain weight grade to the position of the corresponding frame conveying belt, the grading push-out device corresponding to the frame conveying belt works, so that the squid of a certain weight grade conveyed on the grading conveying belt is pushed out to the corresponding frame conveying belt, avoiding pushing out two or more squid at a time, thereby realizing automatic grading and sorting of the squid according to the weight, reducing the labor of the fishing boat, reducing the labor cost, and improving the work efficiency.

[0053] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0054] Specific embodiment 1, as Figure 1 As shown, an automatic squid sorting system for a deep-sea squid fishing vessel includes a feeding conveyor belt 1, a draw conveyor belt 2, a weighing conveyor belt 3, a grading conveyor belt 4, a plurality of framing conveyor belts 5, and a plurality of grading ejection devices 6 corresponding to the framing conveyor belts 5. In this embodiment, the feeding conveyor belt 1, the draw conveyor belt 2, the weighing conveyor belt 3, and the grading conveyor belt 4 have the same conveying direction, and the feeding conveyor belt 1, the draw conveyor belt 2, the weighing conveyor belt 3, and the grading conveyor belt 4 are arranged in sequence along the conveying direction of the grading conveyor belt 4.

[0055] The weighing conveyor belt 3 is a conveyor belt with a weighing function and is equipped with a plurality of weighing sensors distributed sequentially along the conveying direction. The specific method and structure of the weighing conveyor belt 3 with a weighing function are prior art, and its specific structure is not the invention of this application. Therefore, this application does not elaborate on the specific method and structure of the weighing conveyor belt with a weighing function and other conventional technical means.

[0056] The input end of the draw conveyor belt 2 is connected to the output end of the loading conveyor belt 1. The conveying speed of the draw conveyor belt 2 is greater than the conveying speed of the loading conveyor belt 1. In this embodiment, the conveying speed of the draw conveyor belt 2 is greater than twice the conveying speed of the loading conveyor belt 1. For example, the conveying speed of the draw conveyor belt 2 is 2-4 times the conveying speed of the loading conveyor belt 1.

[0057] The input end of the weighing conveyor belt 3 is connected to the output end of the stretch conveyor belt 2. The input end of the grading conveyor belt 4 is connected to the output end of the weighing conveyor belt 3.

[0058] Each frame conveyor belt 5 is sequentially distributed along the conveying direction of the grading conveyor belt 4. In this embodiment, there are five frame conveyor belts 52. Of course, it should be noted that the number of frame conveyor belts 5 can be set as needed. The frame conveyor belts 5 are perpendicular to the grading conveyor belt 4. The input end of the frame conveyor belt 52 is close to the grading conveyor belt 4.

[0059] The grading and ejecting device 6 comprises a push plate 6.1 positioned above the grading conveyor belt 4 and a translation mechanism 6.2 that drives the push plate 6.1. The push plate 6.1 moves perpendicular to the conveying direction of the grading conveyor belt 4. The grading and ejecting device 6 pushes the squid from the grading conveyor belt 4 onto the corresponding tray conveyor belt. The translation mechanism 6.2 is a pneumatic or electric cylinder.

[0060] The specific operation of the automatic squid sorting system on board a deep-sea squid fishing vessel of this embodiment is as follows:

[0061] The squids are placed one by one on the feeding conveyor manually or by mechanical means (such as a manipulator), and then the squids are transported backward in sequence through the feeding conveyor belt 1. When the squids are transported to the stretching conveyor belt 2, since the conveying speed of the stretching conveyor belt 2 is twice that of the feeding conveyor belt 1, the distance between the squids can be effectively increased after the squids pass through the stretching conveyor belt 2 and enter the weighing conveyor belt 3, so that there is a sufficiently large distance between the squids; when the grading pushing device 6 pushes the squids of a certain weight grade conveyed on the grading conveyor belt 4 onto the corresponding frame conveyor belt 5, it is avoided that two or more squids are pushed out at one time, thereby realizing automatic grading and sorting of the squids according to weight.

[0062] The squid are then transported to a weighing conveyor belt 3, where they are weighed and sorted into several weight classes. For example, squid are categorized into five weight classes: I (under 100g), II (100-200g), III (200g-400g), IV (400g-600g), and V (over 600g). The system also stores the weight of each squid. Each weight class corresponds to a framing conveyor belt 5.

[0063] Next, the squids are transported to the grading conveyor belt 4. Since the squids have passed through the stretching conveyor belt 2, there is a sufficiently large distance between the squids. In this way, when the grading conveyor belt 4 transports the squids of a certain weight grade to the corresponding frame conveyor belt 5 position, the grading pushing device 6 corresponding to the frame conveyor belt 5 will work, and the squids of a certain weight grade transported on the grading conveyor belt 4 can be pushed out to the corresponding frame conveyor belt 5, avoiding pushing out two or more squids at a time, thereby realizing automatic grading and sorting of the squids according to weight, reducing the labor of fishing vessels, reducing labor costs, and improving work efficiency.

[0064] Specifically, such as Figure 1 As shown, the automatic squid sorting system for ocean-going squid fishing vessels includes a frame and a controller. A loading conveyor belt 1, a pull-out conveyor belt 2, a weighing conveyor belt 3, a grading conveyor belt 4, and several frame-loading conveyor belts 5 are all mounted on the frame. The frame is installed on the squid fishing vessel. Each translation mechanism 6.2 is also mounted on the frame.

[0065] After the weighing conveyor belt 3 weighs the squids on it, the weight information of each squid is stored in the controller, which then classifies the squids into several grades according to their weight. When the grading conveyor belt 4 conveys squids of a certain weight grade to the corresponding frame conveyor belt 5, the controller controls the grading push-out device 6 corresponding to the frame conveyor belt 5 to operate, pushing the squids conveyed on the grading conveyor belt 4 onto the corresponding frame conveyor belt 5, thereby achieving automatic grading and sorting of the squids according to their weight.

[0066] The upper surfaces of the loading conveyor belt 1, the pull-out conveyor belt 2, the weighing conveyor belt 3, and the grading conveyor belt 4 are located at the same height. The loading conveyor belt 1, the pull-out conveyor belt 2, the weighing conveyor belt 3, and the grading conveyor belt 4 are all arranged horizontally. In this embodiment, the push plate is parallel to the conveying direction of the grading conveyor belt.

[0067] like Figure 1 As shown, the automatic squid sorting system for ocean-going squid fishing vessels also includes a plurality of storage boxes 8 corresponding to the frame conveyor belts 5. The storage boxes 8 are located below the output end of the corresponding frame conveyor belts 5. In this way, the squid conveyed onto the frame conveyor belts 5 according to weight classification can be collectively input into the corresponding storage boxes 8.

[0068] like Figure 1 As shown, the automatic squid sorting system for ocean-going squid fishing vessels also includes a refrigerated conveyor belt 9 that transports storage frames 8 to the vessel's refrigerated storage room 10. The refrigerated conveyor belt 9 is parallel to the grading conveyor belt 4. The loading conveyor belt 5 is located between the refrigerated conveyor belt 9 and the grading conveyor belt 4. Once the squid in the storage frames 8 reaches a set amount, the storage frames 8 are transported via the refrigerated conveyor belt 9 to the vessel's refrigerated storage room for refrigeration.

[0069] like Figure 1 As shown, the automatic sorting system for squid carried by ocean squid fishing vessels also includes a plurality of inclined guide plates 7 corresponding one to one with the frame conveyor belts 5. The inclined guide plates 7 are located above the corresponding frame conveyor belts 5 and are distributed obliquely. The upper ends of the inclined guide plates 7 are located below the upper surface of the grading conveyor belt 4 and close to the upper surface of the grading conveyor belt 4, and the lower ends of the inclined guide plates 7 are close to the upper surface of the corresponding frame conveyor belt 5. After the grading push-out device 6 pushes out the squid conveyed on the grading conveyor belt 4, the squid is input to the corresponding frame conveyor belt 5 through the inclined guide plates 7. In this way, it is ensured that after the squid leaves the grading conveyor belt 4, it can be smoothly input to the corresponding frame conveyor belt 5 through the inclined guide plates 7.

[0070] like Figure 2 As shown, the staged ejection device 6 also includes a stopper 6.5, which is mounted on the frame. In this embodiment, the stopper 6.5 and the translation mechanism 6.2 are located on the same side of the push plate 6.1. Before the push plate 6.1 is ejected, the push plate 6.1 abuts against the stopper 6.5. That is, each time the translation mechanism 6.2 drives the push plate 6.1 back, until the push plate 6.1 abuts against the stopper 6.5, the push plate 6.1 is in its return position.

[0071] Specific embodiment 2: The rest of the structure of this embodiment refers to specific embodiment 1, except that:

[0072] like Figure 2As shown, the grading and pushing device 6 further includes a side baffle 6.3, an electromagnet 6.4 and an elastic element.

[0073] The side baffle 6.3 is hinged on the side of the push plate 6.1 away from the input end of the grading conveyor belt 4. The side baffle 6.3 is vertically distributed.

[0074] The electromagnet 6.4 is fixedly arranged on the push plate 6.1 and is close to the side baffle 6.3. The electromagnet 6.4 and the input end of the grading conveyor belt 4 are located on the same side of the side baffle 6.3.

[0075] In this embodiment, the elastic element is a torsion spring. The elastic element provides a spring force to rotate the side baffle 6.3 toward the magnet until it abuts the electromagnet 6.4. At this point, the side baffle 6.3 is perpendicular to the push plate 6.1. In this embodiment, the elastic force provided by the elastic element is 0.5 to 1 N.

[0076] Before the push plate 6.1 is pushed out, the electromagnet 6.4 is de-energized.

[0077] As the translation mechanism 6.2 pushes the push plate 6.1 out, the electromagnet 6.4 is energized, causing the side baffle 6.3 to be attracted and fixed to the electromagnet 6.4. Specifically, as the translation mechanism 6.2 pushes the push plate 6.1 out, the electromagnet 6.4 is energized, causing the side baffle 6.3 to be attracted and fixed to the electromagnet 6.4. The attraction force between the electromagnet 6.4 and the side baffle 6.3 is much greater than the elastic force provided by the elastic element.

[0078] In the process of the grading pushing device 6 pushing the squids transported on the grading conveyor belt 4 onto the corresponding frame conveyor belt 5, in order to prevent the squids on the grading conveyor belt 4 from being transported backward and separated from the push plate 6.1, the present solution is provided with a side baffle 6.3 on the push plate 6.1 away from the input end of the grading conveyor belt 4, so that the push plate 6.1 can push the squids transported on the grading conveyor belt 4 onto the corresponding frame conveyor belt 5. However, before the push plate 6.1 is pushed out, the squid may be blocked by the side baffle 6.3 on a certain grading pushing device 6, resulting in the squid being unable to be smoothly transported to the designated grading pushing device 6. To solve this problem, the present solution has improved the grading pushing device 6. Before the push plate 6.1 is pushed out, the electromagnet 6.4 is de-energized. If the squid is blocked by the side baffle 6.3 on a certain grading pushing device 6, the squid will overcome the force of the elastic element, causing the side baffle 6.3 to rotate, and then pass over the side baffle 6.3 and continue to be transported backward to the designated grading pushing device 6.

[0079] When the translation mechanism 6.2 pushes the push plate 6.1 out, the electromagnet 6.4 is energized and the side baffle 6.3 is adsorbed and fixed on the electromagnet 6.4. The adsorption of the electromagnet 6.4 is large enough to keep the side baffle 6.3 fixed and not rotate. Therefore, when the push plate 6.1 pushes the squids transported on the grading conveyor belt 4 to the corresponding frame conveyor belt 5, the side baffle 6.3 can prevent the squids on the grading conveyor belt 4 from being transported backward and separated from the push plate 6.1, so that the push plate 6.1 can push the squids transported on the grading conveyor belt 4 to the corresponding frame conveyor belt 5.

[0080] Specific embodiment 3: The rest of the structure of this embodiment refers to specific embodiment 1, except that:

[0081] like Figure 3 As shown, the push plate 6.1 includes a main push plate 6.1.1 and a floating push plate 6.1.2, which are vertically arranged. A vertical guide groove 6.1.3 with an opening facing downward is provided in the main push plate 6.1.1. The floating push plate 6.1.2 is also vertically arranged. The main push plate 6.1.1 is parallel to the floating push plate 6.1.2. In this embodiment, the main push plate 6.1.1 is parallel to the conveying direction of the grading conveyor belt 4. The floating push plate 6.1.2 is slidably arranged in the vertical guide groove 6.1.3. A ball 6.1.4 is provided at the bottom end of the floating push plate 6.1.2. Under the action of its own weight, the floating push plate 6.1.2 moves downward along the vertical guide groove 6.1.3 until the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4. At this time, the distance between the bottom end of the floating push plate 6.1.2 and the upper surface of the grading conveyor belt 4 is less than 2 mm. In this embodiment, when the balls 6.1.4 are supported on the upper surface of the grading conveyor belt 4, the distance between the bottom end of the floating push plate 6.1.2 and the upper surface of the grading conveyor belt 4 is 1-1.5 mm.

[0082] Since squid is a mollusk, it has a large number of squid legs; and there is inevitably a gap between the push plate 6.1 and the upper surface of the grading conveyor belt 4, and since the grading conveyor belt 4 is in a conveying state (the position of the upper surface of the grading conveyor belt 4 will fluctuate up and down in the conveying state), the gap is difficult to control; this makes it easy for the squid legs to be clamped between the push plate 6.1 and the upper surface of the grading conveyor belt 4 during the process of the push plate 6.1 pushing the squid conveyed on the grading conveyor belt 4 to be pushed onto the corresponding frame conveyor belt 5, causing the push plate 6.1 to be stuck and unable to push the squid onto the corresponding frame conveyor belt 5, and causing squid legs and even squid body to be squeezed and damaged. In order to solve this problem, the present solution improves the push plate 6.1. Specifically,

[0083] Since the main push plate 6.1.1 is provided with a floating push plate 6.1.2 that can move up and down, and the floating push plate 6.1.2 moves downward along the vertical guide groove 6.1.3 under the action of its own weight until the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4, at this time, the distance between the bottom end of the floating push plate 6.1.2 and the upper surface of the grading conveyor belt 4 is less than 2 mm; based on this, even if the grading conveyor belt 4 is in the conveying state, the distance between the push plate 6.1 and the upper surface of the grading conveyor belt 4 can be ensured to be less than 2 mm, effectively controlling the gap between the push plate 6.1 and the grading conveyor belt 4 to be kept at a sufficiently small level, thereby effectively reducing the problem of the squid's feet being clamped between the push plate 6.1 and the upper surface of the grading conveyor belt 4, causing the push plate 6.1 to be stuck and unable to push the squid onto the corresponding frame conveyor belt 5, and causing squid feet and even squid body to be squeezed and damaged.

[0084] Further, such as Figure 3 As shown, the grading pushing device 6 also includes a displacement sensor 6.6. The displacement sensor 6.6 is fixedly arranged on the floating push plate 6.1.2 below the main push plate 6.1.1. The displacement sensor 6.6 is used to detect the distance between it and the upper surface of the grading conveyor belt 4 (that is, to detect the distance between the displacement sensor 6.6 itself and the upper surface of the grading conveyor belt 4). In the process of the grading pushing device 6 pushing the squid transported on the grading conveyor belt 4 to the corresponding grading conveyor belt 4, when the displacement sensor 6.6 detects that the distance between it and the upper surface of the grading conveyor belt 4 exceeds the operating set value (for example, when the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4, the distance between the displacement sensor 6.6 itself and the upper surface of the grading conveyor belt 4 is 2 cm, then the set value is 3-5 cm, and the set value is greater than "when the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4, the distance between the displacement sensor 6.6 itself and the upper surface of the grading conveyor belt 4 is 2 cm), the set value is 3-5 cm, and the set value is greater than "when the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4, the distance between the displacement sensor 6.6 itself and the upper surface of the grading conveyor belt 4 is 2 cm, then ... The distance between the upper surfaces of the grading conveyor belt 4 is the same as the distance between the displacement sensor 6.6 and the upper surface of the grading conveyor belt 4, indicating that the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4). Then, the push drive mechanism drives the push plate 6.1 to move back until the floating push plate 6.1.2 moves down and the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4 (when the displacement sensor 6.6 detects that the distance between it and the upper surface of the grading conveyor belt 4 is exactly the same as "When the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4, the distance between the displacement sensor 6.6 itself and the upper surface of the grading conveyor belt 4 is the same", indicating that the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4). Then, the push drive mechanism pushes the push plate 6.1 out again.

[0085] By controlling the gap between the push plate 6.1 and the grading conveyor belt 4 to be kept at a sufficiently small level, the problem of squid feet being clamped between the push plate 6.1 and the upper surface of the grading conveyor belt 4 can be effectively reduced; however, a small amount of squid feet will still be clamped between the push plate 6.1 and the upper surface of the grading conveyor belt 4. In order to further solve this problem, this solution further improves the grading pushing device 6 and the pushing method. Specifically,

[0086] In the process of the grading pushing device 6 pushing the squids conveyed on the grading conveyor belt 4 to the corresponding frame conveyor belt 5, the distance between it and the upper surface of the grading conveyor belt 4 is detected by the displacement sensor 6.6. When the squid feet are clamped between the push plate 6.1 and the upper surface of the grading conveyor belt 4, the floating push plate 6.1.2 is pushed upward. At this time, the distance between the displacement sensor 6.6 and the upper surface of the grading conveyor belt 4 increases, so that the distance between it and the upper surface of the grading conveyor belt 4 detected by the displacement sensor 6.6 exceeds the operation set value, thereby controlling the translation. Mechanism 6.2 drives the push plate 6.1 to move back. During the movement of the push plate 6.1 back, the squid generally remains motionless, thereby separating the push plate 6.1 from the squid's feet. After that, the floating push plate 6.1.2 moves downward under the action of its own weight and supports the ball 6.1.4 on the upper surface of the grading conveyor belt 4. At this time, the distance between it and the upper surface of the grading conveyor belt 4 detected by the displacement sensor 6.6 is less than the set value, thereby controlling the translation mechanism 6.2 to push the push plate 6.1 again, pushing the squid transported on the grading conveyor belt 4 to the corresponding frame conveyor belt 5.

[0087] Further, such as Figure 3 As shown, a spring 6.1.5 is installed in the vertical guide groove 6.1.3. The spring 6.1.5 is located above the floating push plate 6.1.2. Under the action of the spring 6.1.5 and its own weight, the floating push plate 6.1.2 moves downward along the vertical guide groove 6.1.3 until the ball bearing 6.1.4 is supported on the upper surface of the grading conveyor belt 4. In this way, when there are no obstacles between the floating push plate 6.1.2 and the grading conveyor belt 4, the floating push plate 6.1.2 can move downward along the vertical guide groove 6.1.3 under the action of the spring and its own weight until the ball bearing 6.1.4 is supported on the upper surface of the grading conveyor belt 4, thereby effectively controlling the gap between the push plate 6.1 and the grading conveyor belt 4 to a sufficiently small level.

[0088] Specific embodiment 4: The rest of the structure of this embodiment refers to specific embodiment 3, except that:

[0089] like Figure 2 As shown, the grading and pushing device 6 further includes a side baffle 6.3, an electromagnet 6.4 and an elastic element.

[0090] The side baffle 6.3 is hinged on the side of the push plate 6.1 away from the input end of the grading conveyor belt 4. In this embodiment, the side baffle 6.3 is hinged on the side of the main push plate 6.1.1 away from the input end of the grading conveyor belt 4. The side baffle 6.3 is vertically distributed.

[0091] The electromagnet 6.4 is fixedly arranged on the push plate 6.1 and is close to the side baffle 6.3. The electromagnet 6.4 and the input end of the grading conveyor belt 4 are located on the same side of the side baffle 6.3.

[0092] In this embodiment, the elastic element is a torsion spring. The elastic element provides a spring force to rotate the side baffle 6.3 toward the magnet until it abuts the electromagnet 6.4. At this point, the side baffle 6.3 is perpendicular to the push plate 6.1. In this embodiment, the elastic force provided by the elastic element is 0.5 to 1 N.

[0093] Before the push plate 6.1 is pushed out, the electromagnet 6.4 is de-energized.

[0094] As the translation mechanism 6.2 pushes the push plate 6.1 out, the electromagnet 6.4 is energized, causing the side baffle 6.3 to be attracted and fixed to the electromagnet 6.4. Specifically, as the translation mechanism 6.2 pushes the push plate 6.1 out, the electromagnet 6.4 is energized, causing the side baffle 6.3 to be attracted and fixed to the electromagnet 6.4. The attraction force between the electromagnet 6.4 and the side baffle 6.3 is much greater than the elastic force provided by the elastic element.

[0095] During the process of the grading pushing device 6 pushing the squids conveyed on the grading conveyor belt 4 to the corresponding frame conveyor belt 5; especially when the squid feet are clamped between the push plate 6.1 and the upper surface of the grading conveyor belt 4, and the push plate 6.1 moves back, in order to prevent the squids on the grading conveyor belt 4 from being conveyed backward and separated from the push plate 6.1, this solution provides a side baffle 6.3 on the side of the push plate 6.1 away from the input end of the grading conveyor belt 4, so that the push plate 6.1 can push the squids conveyed on the grading conveyor belt 4 to the corresponding frame conveyor belt 5. However, in this case, before the push plate 6.1 is pushed out, the squid may be blocked by the side baffle 6.3 on a certain grading pushing device 6, resulting in the squid being unable to be smoothly transferred to the designated grading pushing device 6. In order to solve this problem, the present solution improves the grading pushing device 6. Before the push plate 6.1 is pushed out, the electromagnet 6.4 is powered off. If the squid is blocked by the side baffle 6.3 on a certain grading pushing device 6, the squid will overcome the force of the elastic element, causing the side baffle 6.3 to rotate, and then pass over the side baffle 6.3 and continue to be transferred to the designated grading pushing device 6.

[0096] When the translation mechanism 6.2 pushes the push plate 6.1 out, the electromagnet 6.4 is energized and the side baffle 6.3 is adsorbed and fixed on the electromagnet 6.4. The adsorption of the electromagnet 6.4 is large enough to keep the side baffle 6.3 fixed and not rotate. Therefore, when the push plate 6.1 pushes the squids transported on the grading conveyor belt 4 to the corresponding frame conveyor belt 5, the side baffle 6.3 can prevent the squids on the grading conveyor belt 4 from being transported backward and separated from the push plate 6.1, so that the push plate 6.1 can push the squids transported on the grading conveyor belt 4 to the corresponding frame conveyor belt 5.

[0097] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent transformation made to the above embodiment based on the technical essence of the present invention still fall within the scope of protection of the technical solution of the present invention.
