Description

Technical Field

[0001] The 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 scale of the squid fishing industry gradually expands, the problems that restrict the high-quality development of squid fishing fisheries are becoming increasingly prominent. First, in recent years, it has been difficult for distant-water fishing vessels to recruit workers, and the labor shortage is serious. The increasingly high wages have caused certain operating pressures on distant-water enterprises. Secondly, the grading, sorting and weighing of squid at sea require a large number of workers and the work intensity is high. Thirdly, with the rapid development of downstream industries such as processing, warehousing and logistics, higher requirements are put forward for the primary processing of squid grading and sorting in the fishing industry, and fishing vessels are required to grade squid more accurately.

[0003] However, the working environment at sea is special and the working conditions are complex. 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 manual sorting is still the main method. Semi-automatic and automated sorting equipment has not been developed and applied accordingly, which restricts 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, the gradual reduction of fishing boat labor, the reduction of labor costs, the reduction of crew work intensity, and the improvement of work efficiency are of great significance to ensure 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 a deep-sea squid fishing vessel, which can automatically grade and sort squids according to weight, thereby reducing the number of workers on fishing vessels, reducing labor costs and improving work efficiency.

[0005] The technical solution of the present invention is: An automatic squid sorting system for a deep-sea squid fishing vessel, comprising: Feeding conveyor belt; 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; A weighing conveyor belt, the input end of which is butted against the output end of the pull-distance conveyor belt; A grading conveyor belt, the input end of which is butted against the output end of the weighing conveyor belt; a plurality of frame conveyor belts sequentially distributed along the conveying direction of the grading conveyor belt; and Several grading push-out devices corresponding to the frame conveyor belts are provided. The grading push-out devices include a push plate located above the grading conveyor belt and a translation mechanism for driving the push plate to move. The grading push-out devices push the squids conveyed on the grading conveyor belts onto the corresponding tray conveyor belts. The specific operation of the automatic squid sorting system on the ocean squid fishing boat of this scheme is as follows: The squids are transported backwards in sequence through the feeding conveyor belt. When the squids are transported to the pull-distance conveyor belt, the conveying speed of the pull-distance conveyor belt is greater than that of the feeding conveyor belt. In this way, after the squids pass through the pull-distance conveyor belt and enter the weighing conveyor belt, the distance between the squids can be effectively increased. Next, the squids are transported to the weighing conveyor belt, where they are weighed and divided into several grades according to their weight. Each weight grade corresponds to a frame conveyor belt. Next, the squids are transported to the grading conveyor belt. After the squids pass through the stretching conveyor belt, the distance between the squids is effectively increased. In this way, when the grading conveyor belt transports squids of a certain weight grade to the corresponding frame conveyor belt position, the grading pushing device corresponding to the frame conveyor belt works, and the squids of a certain weight grade transported on the grading conveyor belt can be pushed out to the corresponding frame conveyor belt, avoiding pushing out two or more squids at a time, thereby realizing automatic grading and sorting of squids according to weight, reducing the labor of fishing vessels, reducing labor costs, and improving work efficiency.

[0006] As preferably, it also comprises a plurality of storage frames corresponding to the framed conveyor belts one by one, and the storage frames are located below the output end of the corresponding framed conveyor belts. In this way, the squids transported to the framed conveyor belts according to weight classification can be centrally input into the corresponding storage frames.

[0007] As a preferred method, the method further includes a refrigerated conveyor belt for conveying the storage frame to a refrigerated room of the ocean squid fishing vessel, wherein the refrigerated conveyor belt is parallel to the grading conveyor belt, and the frame 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 set amount, the storage frame can be transported to the refrigerated room of the ocean squid fishing vessel through the refrigerated conveyor belt for refrigeration.

[0008] As a preference, it further comprises a plurality of inclined guide plates corresponding to the frame conveyor belts, the inclined guide plates being located above the corresponding frame conveyor belts and being inclinedly distributed, and when the grading push-out device pushes out the squids conveyed on the grading conveyor belts, the squids are fed to the corresponding frame conveyor belts through the inclined guide plates. In this way, it is ensured that after the squids are separated from the grading conveyor belts, they can be smoothly fed to the corresponding frame conveyor belts through the inclined guide plates.

[0009] Preferably, the conveying speed of the pull-distance conveyor belt is greater than twice the conveying speed of the feeding conveyor belt. In this way, after the squids pass through the pull-distance conveyor belt, it can be ensured that there is a sufficiently large distance between the squids; when the grading and pushing-out device pushes the squids of a certain weight grade conveyed on the grading conveyor belt to the corresponding frame conveyor belt, it avoids pushing out two or more squids at a time, thereby realizing automatic grading and sorting of the squids according to weight.

[0010] Preferably, the push plate comprises: A main push plate is vertically arranged, and a vertical guide groove with an opening facing downward is provided in the main push plate; Floating push plate, the floating push plate is slidably arranged in the vertical guide groove, and a ball bearing is arranged at the bottom end of the floating push plate. The floating push plate moves downward along the vertical guide groove under the action of its own weight until the ball bearing 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, squid has a large number of squid feet; and there is inevitably a 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 feet to be clamped between the push plate and the upper surface of the grading conveyor belt during 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 feet and even squid body to be squeezed and damaged. In order to solve this problem, the push plate is improved in this scheme. Specifically, 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 a conveying state, it can be ensured that the distance between the push plate and the upper surface of the grading conveyor belt is less than 2 mm, and the gap between the push plate and the grading conveyor belt is 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, resulting in the push plate being 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.

[0011] Preferably, the graded ejection device further comprises: A displacement sensor is arranged on the floating push plate below the main push plate, and the displacement sensor detects the distance between the floating push plate and the upper surface of the grading conveyor belt; In the process of the grading push-out device pushing the squid transported on the grading conveyor belt to the corresponding grading conveyor belt, when the displacement sensor detects that the distance between it 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 down and the ball bearing is supported on the upper surface of the grading conveyor belt, and then the translation mechanism pushes the push plate out again. 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 by controlling the gap between the push plate and the grading conveyor belt to be kept at a sufficiently small level, 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, this solution further improves the grading push-out device and the push-out method. Specifically, When the squid's feet are clamped between the push plate and the upper surface of the grading conveyor belt, the floating push plate will be pushed upward. At this time, the distance between the displacement sensor and the upper surface of the grading conveyor belt increases, so that the distance between the displacement sensor and the upper surface of the grading conveyor belt exceeds the operation set value, thereby controlling the translation mechanism to drive the push plate to move back. During the movement of the push plate back, the squid generally remains motionless, thereby separating the push plate from the squid's feet. Thereafter, the floating push plate moves downward under the action of its own weight and supports the ball bearing on the upper surface of the grading conveyor belt. At this time, the distance between the displacement sensor and the upper surface of the grading conveyor belt is less than the set value, thereby controlling the translation mechanism to push the push plate again, and pushing the squid transported on the grading conveyor belt onto the corresponding frame conveyor belt.

[0012] Preferably, the graded ejection device further comprises: A side baffle, hinged on the side of the push plate away from the input end of the grading conveyor belt; An electromagnet is disposed on the push plate and is close to the side baffle; The elastic element, under the action of the elastic element, the side baffle rotates toward the electromagnet and abuts against the electromagnet; Before the push plate is pushed out, the electromagnet is de-energized; When the translation mechanism pushes the push plate out, the electromagnet is energized and the side baffle is fixed on the electromagnet. When the grading push device pushes the squids conveyed on the grading conveyor belt to the corresponding frame conveyor belt; especially when the squid feet are clamped between the push plate and the upper surface of the grading conveyor belt, when the push plate moves back, in order to prevent the squids on the grading conveyor belt from being transported backward and separated from the push plate, the present solution sets a side baffle on the side of the push plate away from the input end of the grading conveyor belt, so that the push plate can push the squids conveyed on the grading conveyor belt to the corresponding frame conveyor belt. However, in this case, before the push plate is pushed out, the squid may be blocked by a side baffle on a certain grading push device, resulting in the squid being unable to be smoothly transported to the designated grading push device. In order to solve this problem, the present scheme improves the grading push device. Before the push plate is pushed out, the electromagnet is powered off. If the squid is blocked by a side baffle on a certain grading push device, the squid will overcome the force of the elastic element, causing the side baffle to rotate, and then pass over the side baffle and continue to be transported to the designated grading push device.

[0013] In the process of the translation mechanism pushing the push plate out, the electromagnet is energized and the side baffle is adsorbed and fixed on the electromagnet. The adsorption of the electromagnet is large enough to keep the side baffle fixed and not rotate. Therefore, in the process of the push plate pushing the squids transported on the grading conveyor belt to the corresponding frame conveyor belt, the side baffle can prevent the squids on the grading conveyor belt from being transported backward and separated from the push plate, so that the push plate can push the squids transported on the grading conveyor belt to the corresponding frame conveyor belt.

[0014] Preferably, the graded pushing device further comprises a limit block, and before the push plate is pushed out, the push plate abuts against the limit block.

[0015] Preferably, the upper surfaces of the feeding conveyor belt, the pulling conveyor belt, the weighing conveyor belt and the grading conveyor belt are located at the same height.

[0016] The beneficial effects of the present invention are: The squids are transported backward in sequence through the feeding conveyor belt. When the squids are transported to the distance conveyor belt, since the conveying speed of the distance conveyor belt is greater than the conveying speed of the feeding conveyor belt, the distance between the squids can be effectively increased after the squids pass through the distance conveyor belt and enter the weighing conveyor belt; the squids are transported to the weighing conveyor belt, the squids on the weighing conveyor belt are weighed, and the squids are divided into several grades according to weight, and each weight grade corresponds to a frame conveyor belt; the squids are transported to the grading conveyor belt, and the distance between the squids is effectively increased after the squids pass through the distance conveyor belt; in this way, when the grading conveyor belt transports squids of a certain weight grade to the corresponding frame conveyor belt position, the grading pushing device corresponding to the frame conveyor belt works, and the squids of a certain weight grade transported on the grading conveyor belt can be pushed onto the corresponding frame conveyor belt, so as to avoid pushing two or more squids at one time, thereby realizing automatic grading and sorting of squids according to weight, reducing the labor of fishing vessels, reducing labor costs, and improving work efficiency.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Specific embodiment 1, as Figure 1As shown, an automatic squid sorting system for a deep-sea squid fishing vessel includes a feeding conveyor belt 1, a pull-distance conveyor belt 2, a weighing conveyor belt 3, a grading conveyor belt 4, a plurality of frame conveyor belts 5, and a plurality of grading push-out devices 6 corresponding to the frame conveyor belts 5. In this embodiment, the feeding conveyor belt 1, the pull-distance 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 pull-distance conveyor belt 2, the weighing conveyor belt 3 and the grading conveyor belt 4 are sequentially distributed along the conveying direction of the grading conveyor belt 4.

[0022] The weighing conveyor belt 3 is a conveyor belt with a weighing function, on which a plurality of weighing sensors are sequentially distributed 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 point of this application, so this application does not elaborate on the specific method and structure of the conveyor belt with a weighing function and other conventional technical means.

[0023] The input end of the pull-distance conveyor belt 2 is butted against the output end of the feeding conveyor belt 1. The conveying speed of the pull-distance conveyor belt 2 is greater than the conveying speed of the feeding conveyor belt 1. In this embodiment, the conveying speed of the pull-distance conveyor belt 2 is greater than twice the conveying speed of the feeding conveyor belt 1, for example, the conveying speed of the pull-distance conveyor belt 2 is 2-4 times the conveying speed of the feeding conveyor belt 1.

[0024] The input end of the weighing conveyor belt 3 is butted against the output end of the pulling distance conveyor belt 2. The input end of the grading conveyor belt 4 is butted against the output end of the weighing conveyor belt 3.

[0025] Each frame conveyor belt 5 is distributed in sequence 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 belt 5 is perpendicular to the grading conveyor belt 4. The input end of the frame conveyor belt 52 is close to the grading conveyor belt 4.

[0026] The grading push-out device 6 includes a push plate 6.1 located above the grading conveyor belt 4 and a translation mechanism 6.2 for driving the push plate 6.1 to move. The moving direction of the push plate 6.1 is perpendicular to the conveying direction of the grading conveyor belt 4. The grading push-out device 6 pushes the squids conveyed on the grading conveyor belt 4 onto the corresponding tray conveyor belt. The translation mechanism 6.2 is a pneumatic cylinder or an electric cylinder.

[0027] The specific operation of the automatic squid sorting system on board an ocean squid fishing vessel of this embodiment is as follows: The squids are placed one by one on the feeding conveyor by manual means or mechanical devices (such as manipulators), and then the squids are transported backward in sequence through the feeding conveyor belt 1. When the squids are transported to the pulling distance conveyor belt 2, since the conveying speed of the pulling distance conveyor belt 2 is twice that of the feeding conveyor belt 1, after the squids pass through the pulling distance conveyor belt 2 and enter the weighing conveyor belt 3, the distance between the squids can be effectively increased, so that the distance between the squids is large enough; when the grading push-out 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.

[0028] Next, the squid is transported to the weighing conveyor belt 3, where the squid on the weighing conveyor belt 3 is weighed and classified into several grades according to weight. For example, the squid is classified into five grades according to weight, i.e., 100g or less, ii.e., 100-200g, iii.e., 200g-400g, iv.e., 400g-600g, and iv.e., more than 600g. At the same time, the system can store the weight information of each squid. Each weight grade corresponds to a frame conveyor belt 5.

[0029] 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 squids of a certain weight grade to the corresponding position of the frame conveyor belt 5, the grading pushing device 6 corresponding to the frame conveyor belt 5 works, 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.

[0030] Specifically, Figure 1 As shown, the automatic sorting system for squids carried by ocean squid fishing boats also includes a frame and a controller. The feeding conveyor belt 1, the pulling conveyor belt 2, the weighing conveyor belt 3, the grading conveyor belt 4 and a plurality of frame conveyor belts 5 are all installed on the frame. The frame is installed on the squid fishing boat. Each translation mechanism 6.2 is also installed on the frame.

[0031] After the weighing conveyor belt 3 weighs the squids on it, the weight information of each squid will be stored in the controller, and the controller will classify 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 position of the frame conveyor belt 5, the controller controls the grading push-out device 6 corresponding to the frame conveyor belt 5 to work, and pushes the squids transported on the grading conveyor belt 4 to the corresponding frame conveyor belt 5, thereby realizing automatic grading and sorting of squids according to weight.

[0032] The upper surfaces of the feeding conveyor belt 1, the pulling conveyor belt 2, the weighing conveyor belt 3 and the grading conveyor belt 4 are located at the same height. The feeding conveyor belt 1, the pulling conveyor belt 2, the weighing conveyor belt 3 and the grading conveyor belt 4 are all horizontally distributed. In this embodiment, the push plate is parallel to the conveying direction of the grading conveyor belt.

[0033] like Figure 1 As shown, the automatic squid sorting system for ocean squid fishing vessels also includes a plurality of storage frames 8 corresponding to the frame conveyor belts 5. The storage frames 8 are located below the output end of the corresponding frame conveyor belts 5. In this way, the squids transported to the frame conveyor belts 5 according to weight classification can be collectively input into the corresponding storage frames 8.

[0034] like Figure 1 As shown, the automatic sorting system for squids carried by a distant-water squid fishing vessel also includes a refrigerated conveyor belt 9 for conveying the storage frame 8 to a refrigerated room 10 of the distant-water squid fishing vessel. The refrigerated conveyor belt 9 is parallel to the grading conveyor belt 4. The frame conveyor belt 5 is located between the refrigerated conveyor belt 9 and the grading conveyor belt 4. In this way, when the squids in the storage frame 8 reach a set amount, the storage frame 8 can be conveyed into the refrigerated room of the distant-water squid fishing vessel through the refrigerated conveyor belt 9 for refrigeration.

[0035] 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 to 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 end of the inclined guide plate 7 is 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 end of the inclined guide plate 7 is close to the upper surface of the corresponding frame conveyor belt 5. When 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 plate 7. In this way, it is ensured that after the squid is separated from the grading conveyor belt 4, it can be smoothly input to the corresponding frame conveyor belt 5 through the inclined guide plate 7.

[0036] like Figure 2 As shown, the grading push-out device 6 also includes a limit block 6.5, which is arranged on the frame. In this embodiment, the limit block 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 pushed out, the push plate 6.1 abuts against the limit block 6.5. That is, each time the translation mechanism 6.2 drives the push plate 6.1 to move back, until the push plate 6.1 abuts against the limit block 6.5, at this time, the push plate 6.1 is in a state of returning and resetting.

[0037] Specific embodiment 2: The rest of the structure of this embodiment refers to the specific embodiment 1, except that: like Figure 2 As shown, the grading and pushing device 6 further comprises a side baffle 6.3, an electromagnet 6.4 and an elastic element.

[0038] 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.

[0039] The electromagnet 6.4 is fixedly arranged on the push plate 6.1, and the electromagnet 6.4 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.

[0040] In this embodiment, the elastic element is a torsion spring. The elastic element provides elastic force to rotate the side baffle 6.3 toward the magnet until the side baffle 6.3 abuts against the electromagnet 6.4. At this time, 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 1N.

[0041] Before the push plate 6.1 is pushed out, the electromagnet 6.4 is de-energized.

[0042] 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. Specifically, when the translation mechanism 6.2 pushes the push plate 6.1 out, the electromagnet 6.4 is energized, so that the side baffle 6.3 is adsorbed and fixed on the electromagnet 6.4. The adsorption force between the electromagnet 6.4 and the side baffle 6.3 is much greater than the elastic force provided by the elastic element.

[0043] In the process of the grading push device 6 pushing the squids transported on the grading conveyor belt 4 to 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 sets 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 to the corresponding frame conveyor belt 5. However, in this way, before the push plate 6.1 is pushed out, the squid may be blocked by the side baffle 6.3 on a certain grading push device 6, resulting in the squid being unable to be smoothly transported to the designated grading push device 6. In order to solve this problem, the present solution improves the grading push 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 push 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 push device 6.

[0044] 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.

[0045] Specific embodiment 3: The rest of the structure of this embodiment refers to the specific embodiment 1, the difference is that: 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 distributed. 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 distributed. 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. 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. In this embodiment, when the ball 6.1.4 is 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.

[0046] Since squid is a mollusk, it has a large number of squid feet; 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 upper surface position 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 feet 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 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 feet and even squid body to be squeezed and damaged. In order to solve this problem, the present scheme improves the push plate 6.1. Specifically, 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 a conveying state, it can also ensure that the distance between the push plate 6.1 and the upper surface of the grading conveyor belt 4 is less than 2 mm, and the gap between the push plate 6.1 and the grading conveyor belt 4 is effectively controlled to be kept at a sufficiently small level, thereby effectively reducing the problem of the squid feet being clamped between the push plate 6.1 and the upper surface of the grading conveyor belt 4, resulting in the push plate 6.1 being 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.

[0047] Further, such as Figure 3 As shown, the grading push-out 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 push-out device 6 pushing the squids 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 operation 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, 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 The push drive mechanism drives the push plate 6.1 to move back until the floating push plate 6.1.2 moves down and supports the ball 6.1.4 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", it means that the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4), and then the push drive mechanism pushes the push plate 6.1 out again.

[0048] 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, the present solution further improves the grading push-out device 6 and the push-out method. Specifically, In the process of the grading push 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 will be pushed up. 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 the displacement sensor 6.6 and the upper surface of the grading conveyor belt 4 exceeds the operation setting value, thereby controlling the translation. The 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 down 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 the displacement sensor 6.6 and the upper surface of the grading conveyor belt 4 is less than the set value, thereby controlling the translation mechanism 6.2 to push the push plate 6.1 again, and push the squid transported on the grading conveyor belt 4 to the corresponding frame conveyor belt 5.

[0049] Further, such as Figure 3 As shown, a spring 6.1.5 is provided in the vertical guide groove 6.1.3. The spring 6.1.5 is located above the floating push plate 6.1.2. The floating push plate 6.1.2 moves downward along the vertical guide groove 6.1.3 under the action of the spring 6.1.5 and its own weight until the ball 6.1.4 is supported on the upper surface of the grading conveyor belt 4. In this way, when there is no obstacle between the floating push plate 6.1.2 and the grading conveyor belt 4, it can be ensured that the floating push plate 6.1.2 moves downward along the vertical guide groove 6.1.3 under the action of the spring and its own weight until the ball 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 be kept at a sufficiently small level.

[0050] Specific embodiment 4: The rest of the structure of this embodiment refers to specific embodiment 3, except that: like Figure 2 As shown, the grading and pushing device 6 further comprises a side baffle 6.3, an electromagnet 6.4 and an elastic element.

[0051] 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.

[0052] The electromagnet 6.4 is fixedly arranged on the push plate 6.1, and the electromagnet 6.4 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.

[0053] In this embodiment, the elastic element is a torsion spring. The elastic element provides elastic force to rotate the side baffle 6.3 toward the magnet until the side baffle 6.3 abuts against the electromagnet 6.4. At this time, 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 1N.

[0054] Before the push plate 6.1 is pushed out, the electromagnet 6.4 is de-energized.

[0055] 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. Specifically, when the translation mechanism 6.2 pushes the push plate 6.1 out, the electromagnet 6.4 is energized, so that the side baffle 6.3 is adsorbed and fixed on the electromagnet 6.4. The adsorption force between the electromagnet 6.4 and the side baffle 6.3 is much greater than the elastic force provided by the elastic element.

[0056] 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, during the process of the push plate 6.1 moving 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, the present 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 transmitted to the designated grading pushing device 6. In order to solve this problem, the present scheme 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 transmitted to the designated grading pushing device 6.

[0057] 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.

[0058] 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 falls within the protection scope of the technical solution of the present invention.
