Description

Technical Field

[0001] The invention relates to the field of squid grading and sorting, and in particular to a squid grading device. 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 a squid grading device which can automatically grade and sort squids according to weight, thereby reducing the number of workers on fishing boats, reducing labor costs and improving work efficiency.

[0005] The technical solution of the present invention is: A squid grading device, comprising: The main conveyor belt for conveying squids has a weighing function; A plurality of graded conveyor belts sequentially distributed along the conveying direction of the main conveyor belt; Several squid pushing mechanisms corresponding to the grading conveyor belts are provided. The squid pushing mechanisms include a push plate located above the main conveyor belt and a push drive mechanism for driving the push plate to move. The moving direction of the push plate is perpendicular to the conveying direction of the main conveyor belt. The squid pushing mechanism pushes the squids conveyed on the main conveyor belt to the corresponding grading conveyor belt. The specific operation of a squid grading device of this scheme is as follows: After the squids enter the main conveyor belt in turn, the squids on the main conveyor belt are weighed and divided into several grades according to their weight, and each weight grade corresponds to a grading conveyor belt; when the main conveyor belt conveys squids of a certain weight grade to the corresponding grading conveyor belt position, the squid pushing mechanism corresponding to the grading conveyor belt works to push the squids conveyed on the main conveyor belt to the corresponding grading conveyor belt, 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] 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 main conveyor belt. At this time, the distance between the bottom end of the floating push plate and the upper surface of the main 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 main conveyor belt, and since the main conveyor belt is in a conveying state (the position of the upper surface of the main 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 main conveyor belt during the process of the push plate pushing the squid conveyed on the main conveyor belt to the corresponding grading conveyor belt, resulting in the push plate being stuck and unable to push the squid to the corresponding grading conveyor belt, as well as squid feet and even squid body being 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 main conveyor belt, at this time, the distance between the bottom end of the floating push plate and the upper surface of the main conveyor belt is less than 2 mm; based on this, even if the main conveyor belt is in the conveying state, it can also ensure that the distance between the push plate and the upper surface of the main conveyor belt is less than 2 mm, and the gap between the push plate and the main 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 main conveyor belt, resulting in the push plate being stuck and unable to push the squid onto the corresponding grading conveyor belt, and causing squid feet and even squid body to be squeezed and damaged.

[0007] Preferably, the squid pushing mechanism further comprises a displacement sensor, which 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 main conveyor belt; In the process of the squid pushing mechanism pushing the squid conveyed on the main conveyor belt to the corresponding grading conveyor belt, when the displacement sensor detects that the distance between it and the upper surface of the main conveyor belt exceeds the operation setting value, the push drive 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 main conveyor belt, and then the push drive 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 main conveyor belt can be effectively reduced by controlling the gap between the push plate and the main 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 main conveyor belt. In order to further solve this problem, this solution further improves the squid pushing mechanism and the pushing method. Specifically, When the squid feet are clamped between the push plate and the upper surface of the main 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 main conveyor belt increases, so that the distance between the displacement sensor and the upper surface of the main conveyor belt exceeds the operation setting value, thereby controlling the push drive 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 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 main conveyor belt. At this time, the distance between the displacement sensor and the upper surface of the main conveyor belt is less than the setting value, thereby controlling the push drive mechanism to push the push plate again, and pushing the squid transported on the main conveyor belt to the corresponding grading conveyor belt.

[0008] Preferably, a spring is provided in the vertical guide groove, and the spring is located above the floating push plate. The floating push plate moves downward along the vertical guide groove under the action of the spring and its own weight until the ball bearing is supported on the upper surface of the main conveyor belt. In this way, when there is no obstacle between the floating push plate and the main conveyor belt, the floating push plate can be ensured to move downward along the vertical guide groove under the action of the spring and its own weight until the ball bearing is supported on the upper surface of the main conveyor belt, thereby effectively controlling the gap between the push plate and the main conveyor belt to be kept at a sufficiently small level.

[0009] Preferably, the squid pushing mechanism further comprises: Fixed setting roller; A side baffle is hinged on a side of the push plate away from the input end of the main conveyor belt, and one side of the side baffle is provided with a driving inclined surface cooperating with the roller; A magnet, fixed to the push plate; An elastic element, providing elastic force to rotate the side baffle toward the magnet; Before the push plate is pushed out, the driving bevel is against the roller, at which time the side baffle is separated from the magnet; in the process of the push drive mechanism pushing the push plate out, when the roller is separated from the driving bevel, the side baffle is against the magnet under the action of the elastic element, at which time the side baffle is fixed to the magnet by adsorption, and the side baffle is perpendicular to the push plate. In the process of the squid pushing mechanism pushing the squid transported on the main conveyor belt to the corresponding grading conveyor belt; especially when the squid feet are clamped between the push plate and the upper surface of the main conveyor belt, in the process of the push plate moving back, in order to prevent the squid on the main 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 main conveyor belt, so that the push plate can push the squid transported on the main conveyor belt to the corresponding grading conveyor belt. However, in this case, before the push plate is pushed out, the squid may be blocked by the side baffle on a squid pushing mechanism, resulting in the squid being unable to be smoothly transmitted to the designated squid pushing mechanism. In order to solve this problem, the present invention improves the squid pushing mechanism. Before the push plate is pushed out, the driving inclined surface is against the roller. At this time, the side baffle is separated from the magnet. If the squid is blocked by the side baffle on a squid pushing mechanism, 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 transmitted to the designated squid pushing mechanism.

[0010] In the process of the push driving mechanism pushing the push plate out, when the roller separates from the driving inclined plane, the side baffle plate is pressed against the magnet under the action of the elastic element. At this time, the side baffle plate is adsorbed and fixed on the magnet; the adsorption of the magnet is large enough to keep the side baffle plate fixed and not rotate. Therefore, in the process of the push plate pushing the squid transported on the main conveyor belt to the corresponding grading conveyor belt, the side baffle plate can prevent the squid on the main conveyor belt from being transported backward and separated from the push plate, so that the push plate can push the squid transported on the main conveyor belt to the corresponding grading conveyor belt.

[0011] Preferably, the squid pushing mechanism further comprises a limiting block, and before the pushing plate is pushed out, the pushing plate abuts against the limiting block.

[0012] As a preference, it further comprises a plurality of squid guide plates corresponding to the grading conveyor belts, wherein the squid guide plates are located above the corresponding grading conveyor belts and are distributed obliquely, and the upper ends of the squid guide plates are located below the upper surface of the main conveyor belt. After the squid pushing mechanism pushes out the squids transmitted on the main conveyor belt, the squids are input to the corresponding grading conveyor belts through the squid guide plates. In this way, it is ensured that after the squids are separated from the main conveyor belt, they can be smoothly input to the corresponding grading conveyor belts through the squid guide plates.

[0013] Preferably, the main conveyor belt and the grading conveyor belt are both horizontally distributed, and the grading conveyor belt is perpendicular to the main conveyor belt.

[0014] Preferably, the push drive mechanism is a pneumatic cylinder or an electric cylinder.

[0015] The beneficial effects of the present invention are as follows: after the squids enter the main conveyor belt in turn, the squids on the main conveyor belt are weighed and divided into several grades according to weight, and each weight grade corresponds to a grading conveyor belt; when the main conveyor belt conveys squids of a certain weight grade to the corresponding grading conveyor belt position, the squid pushing mechanism corresponding to the grading conveyor belt works to push the squids conveyed on the main conveyor belt onto the corresponding grading conveyor belt, 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.

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 1 As shown, a squid grading device comprises a main conveyor belt 1, a plurality of grading conveyor belts 2 sequentially distributed along the conveying direction of the main conveyor belt 1, and a plurality of squid pushing mechanisms 3.

[0022] The main conveyor belt 1 is used to convey squids. The main conveyor belt 1 is horizontally distributed. The main conveyor belt 1 is a conveyor belt with a weighing function, and is provided with a plurality of weighing sensors distributed in sequence along the conveying direction. The specific method and structure of the conveyor belt 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] In this embodiment, there are five grading conveyor belts 2 (three grading conveyor belts 2 are shown in the figure, and two are not shown). Of course, it should be noted that the number of grading conveyor belts 2 can be set as needed. The grading conveyor belts 2 are perpendicular to the main conveyor belt 1. The grading conveyor belts 2 are all horizontally distributed. The input end of the grading conveyor belt 2 is close to the main conveyor belt 1.

[0024] The squid pushing mechanism 3 corresponds to the grading conveyor belt 2. The squid pushing mechanism 3 includes a push plate 3.1 located above the main conveyor belt 1 and a push drive mechanism 3.2 for driving the push plate 3.1 to move. The push drive mechanism 3.2 is a cylinder or an electric cylinder.

[0025] The moving direction of the push plate 3.1 is perpendicular to the conveying direction of the main conveyor belt 1. The squid pushing mechanism 3 pushes the squids conveyed on the main conveyor belt 1 onto the corresponding grading conveyor belt 2.

[0026] The specific operation of a squid grading device of this embodiment is as follows: The squids are placed one by one on the main conveyor belt 1 manually or by mechanical devices (such as manipulators). After the squids enter the main conveyor belt 1 in turn, the squids on the main conveyor belt 1 are weighed and classified into several grades according to weight. For example, the squids are classified into five grades from Ⅰ to Ⅴ according to weight, Ⅰ is less than 100g, Ⅱ is 100-200g, Ⅲ is 200g-400g, Ⅳ is 400g-600g, and Ⅴ is more than 600g. At the same time, the squid grading device can store the weight information of each squid. Each weight grade corresponds to a grading conveyor belt 2.

[0027] When the main conveyor belt 1 transports squids of a certain weight grade to the corresponding grading conveyor belt 2, the squid pushing mechanism 3 corresponding to the grading conveyor belt 2 works to push the squids transported on the main conveyor belt 1 onto the corresponding grading conveyor belt 2, 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.

[0028] Specifically, a squid grading device further comprises a frame. A main conveyor belt 1 is mounted on the frame. Each grading conveyor belt 2 is also mounted on the frame. The frame is mounted on a squid fishing boat. A push drive mechanism 3.2 is mounted on the frame.

[0029] like Figure 1 As shown, a squid grading device further includes a plurality of squid guide plates 4 corresponding to the grading conveyor belts 2. The squid guide plates 4 are located above the corresponding grading conveyor belts 2. The squid guide plates 4 are tilted, the upper ends of the squid guide plates 4 are located below the upper surface of the main conveyor belt 1 and close to the upper surface of the main conveyor belt 1, and the lower ends of the squid guide plates 4 are close to the upper surface of the corresponding grading conveyor belt 2. When the squid pushing mechanism 3 pushes the squid conveyed on the main conveyor belt 1, the squid is input to the corresponding grading conveyor belt 2 through the squid guide plates 4. In this way, it is ensured that after the squid leaves the main conveyor belt 1, it can be smoothly input to the corresponding grading conveyor belt 2 through the squid guide plates 4.

[0030] like Figure 2 As shown, the squid pushing mechanism 3 also includes a limit block 3.3, which is arranged on the frame. In this embodiment, the limit block 3.3 and the push drive mechanism are located on the same side of the push plate 3.1. Before the push plate 3.1 is pushed out, the push plate 3.1 abuts against the limit block 3.3. That is, each time the push drive mechanism 3.2 drives the push plate 3.1 to move back, until the push plate 3.1 abuts against the limit block 3.3, at this time, the push plate 3.1 is in a moving back reset state.

[0031] Specific embodiment 2: The rest of the structure of this embodiment refers to the specific embodiment 1, except that: like Figure 2 , Figure 3 As shown, the squid pushing mechanism 3 also includes a roller 3.6, a side baffle 3.4, a magnet 3.5 and an elastic element. The roller 3.6 is fixedly arranged on the frame (the fixed arrangement here means that the position of the roller 3.6 is fixed), and the roller 3.6 can rotate. The roller 3.6 and the limit block 3.3 are located on the same side of the push plate 3.1.

[0032] The side baffle 3.4 is hinged on the side of the push plate 3.1 away from the input end of the main conveyor belt 1. The side of the side baffle 3.4 is vertically distributed. A driving inclined surface 3.7 cooperating with the roller 3.6 is provided on one side of the side baffle 3.4. In this embodiment, the driving inclined surface 3.7 and the roller 3.6 are located on the same side of the push plate 3.1.

[0033] The magnet 3.5 is fixed on the push plate 3.1. The magnet 3.5 and the limit block 3.3 are located on opposite sides of the push plate 3.1. The magnet 3.5 is close to the side baffle 3.4. The magnet 3.5 is used to adsorb and fix the side baffle 3.4 on the push plate 3.1. The magnet 3.5 in this embodiment is a strong magnet 3.5.

[0034] In this embodiment, the elastic element is a torsion spring. The elastic element provides elastic force to rotate the side baffle 3.4 toward the magnet 3.5 until the side baffle 3.4 abuts against the magnet 3.5. At this time, the side baffle 3.4 is adsorbed and fixed on the magnet 3.5, and the side baffle 3.4 is perpendicular to the push plate 3.1. The adsorption force between the magnet 3.5 and the side baffle 3.4 is much greater than the elastic force provided by the elastic element. In this embodiment, the elastic force provided by the elastic element is 0.5 to 1N.

[0035] Before the push plate 3.1 is pushed out (ie the push plate 3.1 abuts against the limit block 3.3), the driving inclined surface 3.7 abuts against the roller 3.6, and at this time, the side baffle 3.4 is separated from the magnet 3.5.

[0036] When the push drive mechanism 3.2 pushes the push plate 3.1 out, when the roller 3.6 separates from the driving slope 3.7, the side baffle 3.4 abuts against the magnet 3.5 under the action of the elastic element. At this time, the side baffle 3.4 is adsorbed and fixed on the magnet 3.5, and the side baffle 3.4 is perpendicular to the push plate 3.1.

[0037] When the push drive mechanism 3.2 drives the push plate 3.1 to move back and reset, the inclined surface will abut against the roller 3.6 and drive the side baffle 3.4 to rotate away from the input end of the main conveyor belt 1, so that the side baffle 3.4 is separated from the magnet 3.5.

[0038] During the process of the squid pushing mechanism 3 pushing the squids transported on the main conveyor belt 1 to the corresponding grading conveyor belt 2; especially when the squid feet are clamped between the push plate 3.1 and the upper surface of the main conveyor belt 1, during the process of the push plate 3.1 moving back, in order to prevent the squids on the main conveyor belt 1 from being transported backward and detached from the push plate 3.1, the present solution provides a side baffle 3.4 on the side of the push plate 3.1 away from the input end of the main conveyor belt 1, so that the push plate 3.1 can push the squids transported on the main conveyor belt 1 to the corresponding grading conveyor belt 2. However, in this case, before the push plate 3.1 is pushed out, the squid may be blocked by the side baffle 3.4 on a squid pushing mechanism 3, resulting in the squid being unable to be smoothly transmitted to the designated squid pushing mechanism 3. In order to solve this problem, the present solution improves the squid pushing mechanism 3. Before the push plate 3.1 is pushed out, the driving inclined surface 3.7 is against the roller 3.6. At this time, the side baffle 3.4 is separated from the magnet 3.5. If the squid is blocked by the side baffle 3.4 on a squid pushing mechanism 3, the squid will overcome the force of the elastic element, causing the side baffle 3.4 to rotate, and then pass over the side baffle 3.4 and continue to be transmitted to the designated squid pushing mechanism 3.

[0039] When the push drive mechanism 3.2 pushes the push plate 3.1 out, when the roller 3.6 separates from the driving inclined surface 3.7, the side baffle 3.4 abuts against the magnet 3.5 under the action of the elastic element. At this time, the side baffle 3.4 is adsorbed and fixed on the magnet 3.5; the adsorption of the magnet 3.5 is large enough to keep the side baffle 3.4 fixed and not rotate. Therefore, when the push plate 3.1 pushes the squids transported on the main conveyor belt 1 to the corresponding grading conveyor belt 2, the side baffle 3.4 can prevent the squids on the main conveyor belt 1 from being transported backward and separated from the push plate 3.1, so that the push plate 3.1 can push the squids transported on the main conveyor belt 1 to the corresponding grading conveyor belt 2.

[0040] Specific embodiment three, as Figure 1 , Figure 4 As shown, a squid grading device comprises a main conveyor belt 1, a plurality of grading conveyor belts 2 sequentially distributed along the conveying direction of the main conveyor belt 1, and a plurality of squid pushing mechanisms 3.

[0041] The main conveyor belt 1 is used to convey squids. The main conveyor belt 1 is horizontally distributed. The main conveyor belt 1 is a conveyor belt with a weighing function, and is provided with a plurality of weighing sensors distributed in sequence along the conveying direction. The specific method and structure of the conveyor belt 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.

[0042] In this embodiment, there are five grading conveyor belts 2 (three grading conveyor belts 2 are shown in the figure, and two are not shown). Of course, it should be noted that the number of grading conveyor belts 2 can be set as needed. The grading conveyor belts 2 are perpendicular to the main conveyor belt 1. The grading conveyor belts 2 are all horizontally distributed. The input end of the grading conveyor belt 2 is close to the main conveyor belt 1.

[0043] The squid pushing mechanism 3 corresponds to the grading conveyor belt 2. The squid pushing mechanism 3 includes a push plate 3.1 located above the main conveyor belt 1 and a push drive mechanism 3.2 for driving the push plate 3.1 to move. The squid pushing mechanism 3 is a pneumatic cylinder or an electric cylinder.

[0044] The moving direction of the push plate 3.1 is perpendicular to the conveying direction of the main conveyor belt 1. The squid pushing mechanism 3 pushes the squids conveyed on the main conveyor belt 1 onto the corresponding grading conveyor belt 2.

[0045] The push plate 3.1 includes a main push plate 3.11 and a floating push plate 3.12 which are vertically arranged. A vertical guide groove 3.13 with an opening facing downward is provided in the main push plate 3.11. The floating push plate 3.12 is also vertically arranged. The main push plate 3.11 is parallel to the floating push plate 3.12. In this embodiment, the main push plate 3.11 is parallel to the conveying direction of the main conveyor belt 1. The floating push plate 3.12 is slidably arranged in the vertical guide groove 3.13. A ball 3.15 is provided at the bottom end of the floating push plate 3.12. Under the action of its own weight, the floating push plate 3.12 moves downward along the vertical guide groove 3.13 until the ball 3.15 is supported on the upper surface of the main conveyor belt 1. At this time, the distance between the bottom end of the floating push plate 3.12 and the upper surface of the main conveyor belt 1 is less than 2 mm. In this embodiment, when the ball 3.15 is supported on the upper surface of the main conveyor belt 1, the distance between the bottom end of the floating push plate 3.12 and the upper surface of the main conveyor belt 1 is 1-1.5 mm.

[0046] The specific operation of a squid grading device of this embodiment is as follows: The squids are placed one by one on the main conveyor belt 1 by manual means or mechanical devices (such as manipulators). After the squids enter the main conveyor belt 1 in turn, the squids on them are weighed by the main conveyor belt 1, and the squids are divided into several grades according to weight. For example, the squids are divided into five grades from Ⅰ to Ⅴ according to weight, Ⅰ is less than 100g, Ⅱ is 100-200g, Ⅲ is 200g-400g, Ⅳ is 400g-600g, and Ⅴ is more than 600g. At the same time, the squid grading device can store the weight information of each squid. Each weight grade corresponds to a grading conveyor belt 2. When the main conveyor belt 1 transports squids of a certain weight grade to the corresponding grading conveyor belt 2 position, the squid pushing mechanism 3 corresponding to the grading conveyor belt 2 works to push the squids conveyed on the main conveyor belt 1 to the corresponding grading conveyor belt 2, thereby realizing automatic grading and sorting of squids according to weight, reducing the labor of fishing boats, reducing labor costs, and improving work efficiency.

[0047] On the other hand, since squid is a mollusk, it has a large number of squid legs; and there is inevitably a gap between the push plate 3.1 and the upper surface of the main conveyor belt 1, and since the main conveyor belt 1 is in a conveying state (the upper surface position of the main conveyor belt 1 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 3.1 and the upper surface of the main conveyor belt 1 during the process of the push plate 3.1 pushing the squid conveyed on the main conveyor belt 1 onto the corresponding grading conveyor belt 2, causing the push plate 3.1 to be stuck and unable to push the squid onto the corresponding grading conveyor belt 2, and causing squid legs and even squid body to be squeezed and damaged. In order to solve this problem, the push plate 3.1 is improved in this embodiment. Specifically, Since the main push plate 3.11 is provided with a floating push plate 3.12 that can move up and down, and the floating push plate 3.12 moves downward along the vertical guide groove 3.13 under the action of its own weight until the ball 3.15 is supported on the upper surface of the main conveyor belt 1, at this time, the distance between the bottom end of the floating push plate 3.12 and the upper surface of the main conveyor belt 1 is 1-1.5 mm; based on this, even if the main conveyor belt 1 is in the conveying state, it can also ensure that the distance between the push plate 3.1 and the upper surface of the main conveyor belt 1 is 1-1.5 mm, and the gap between the push plate 3.1 and the main conveyor belt 1 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 3.1 and the upper surface of the main conveyor belt 1, causing the push plate 3.1 to be stuck and unable to push the squid onto the corresponding grading conveyor belt 2, as well as causing squid feet and even squid body to be squeezed and damaged.

[0048] Specifically, a squid grading device also includes a frame and a controller. The main conveyor belt 1 is installed on the frame. Each grading conveyor belt 2 is also installed on the frame. The frame is installed on a squid fishing boat. The push drive mechanism 3.2 is installed on the frame.

[0049] After the main conveyor belt 1 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 main conveyor belt 1 conveys squids of a certain weight grade to the corresponding grading conveyor belt 2, the controller controls the squid pushing mechanism 3 corresponding to the grading conveyor belt 2 to work, and pushes the squids conveyed on the main conveyor belt 1 to the corresponding grading conveyor belt 2, thereby realizing automatic grading and sorting of squids according to weight.

[0050] like Figure 1 As shown, a squid grading device further includes a plurality of squid guide plates 4 corresponding to the grading conveyor belts 2. The squid guide plates 4 are located above the corresponding grading conveyor belts 2. The squid guide plates 4 are tilted, the upper ends of the squid guide plates 4 are located below the upper surface of the main conveyor belt 1 and close to the upper surface of the main conveyor belt 1, and the lower ends of the squid guide plates 4 are close to the upper surface of the corresponding grading conveyor belt 2. When the squid pushing mechanism 3 pushes the squid conveyed on the main conveyor belt 1, the squid is input to the corresponding grading conveyor belt 2 through the squid guide plates 4. In this way, it is ensured that after the squid leaves the main conveyor belt 1, it can be smoothly input to the corresponding grading conveyor belt 2 through the squid guide plates 4.

[0051] Further, such as Figure 2As shown, the squid pushing mechanism 3 also includes a limit block 3.3, which is arranged on the frame. In this embodiment, the limit block 3.3 and the push drive mechanism are located on the same side of the push plate 3.1. Before the push plate 3.1 is pushed out, the push plate 3.1 abuts against the limit block 3.3. That is, each time the push drive mechanism 3.2 drives the push plate 3.1 to move back, until the push plate 3.1 abuts against the limit block 3.3, at this time, the push plate 3.1 is in a moving back reset state.

[0052] Further, such as Figure 4 As shown, the squid pushing mechanism 3 also includes a displacement sensor 3.8. The displacement sensor 3.8 is fixedly arranged on the floating push plate 3.12 below the main push plate 3.11. The displacement sensor 3.8 is used to detect the distance between it and the upper surface of the main conveyor belt 1 (that is, to detect the distance between the displacement sensor 3.8 itself and the upper surface of the main conveyor belt 1). In the process of the squid pushing mechanism 3 pushing the squids conveyed on the main conveyor belt 1 to the corresponding grading conveyor belt 2, when the displacement sensor 3.8 detects that the distance between it and the upper surface of the main conveyor belt 1 exceeds the operation set value (for example, when the ball 3.15 is supported on the upper surface of the main conveyor belt 1, the distance between the displacement sensor 3.8 itself and the upper surface of the main conveyor belt 1 is 2 cm, then the set value is 3-5 cm, and the set value is greater than "When the ball 3.15 is supported on the upper surface of the main conveyor belt 1, the distance between the displacement sensor 3.8 itself and the upper surface of the main conveyor belt 1 The push drive mechanism 3.2 drives the push plate 3.1 to move back until the floating push plate 3.12 moves down and supports the ball 3.15 on the upper surface of the main conveyor belt 1 (when the displacement sensor 3.8 detects that the distance between it and the upper surface of the main conveyor belt 1 is exactly the same as "when the ball 3.15 is supported on the upper surface of the main conveyor belt 1, the distance between the displacement sensor 3.8 itself and the upper surface of the main conveyor belt 1 is the same", it means that the ball 3.15 is supported on the upper surface of the main conveyor belt 1), and then the push drive mechanism 3.2 pushes the push plate 3.1 out again.

[0053] By controlling the gap between the push plate 3.1 and the main conveyor belt 1 to be kept at a sufficiently small level, the problem of squid feet being clamped between the push plate 3.1 and the upper surface of the main conveyor belt 1 can be effectively reduced; however, a small amount of squid feet will still be clamped between the push plate 3.1 and the upper surface of the main conveyor belt 1. In order to further solve this problem, the present embodiment further improves the squid pushing mechanism 3 and the pushing method. Specifically, When the squid pushing mechanism 3 pushes the squids conveyed on the main conveyor belt 1 to the corresponding grading conveyor belt 2, the distance between it and the upper surface of the main conveyor belt 1 is detected by the displacement sensor 3.8. When the squid foot is clamped between the push plate 3.1 and the upper surface of the main conveyor belt 1, the floating push plate 3.12 will be pushed upward. At this time, the distance between the displacement sensor 3.8 and the upper surface of the main conveyor belt 1 increases, so that the distance between the displacement sensor 3.8 and the upper surface of the main conveyor belt 1 detected by the displacement sensor 3.8 exceeds the operation set value. When the displacement sensor 3.8 detects that the distance between it and the upper surface of the main conveyor belt 1 exceeds the operation set value, the push drive mechanism 3.2 is controlled to drive the push plate 3.1 to move back. During the movement of the push plate 3.1 back, the squid generally remains motionless, thereby separating the push plate 3.1 from the squid's feet. After that, the floating push plate 3.12 moves downward under the action of its own weight and supports the ball 3.15 on the upper surface of the main conveyor belt 1. At this time, the distance between it and the upper surface of the main conveyor belt 1 detected by the displacement sensor 3.8 is less than the set value, thereby controlling the push drive mechanism 3.2 to push the push plate 3.1 again, and push the squid transported on the main conveyor belt 1 to the corresponding grading conveyor belt 2.

[0054] Further, such as Figure 4 As shown, a spring 3.14 is provided in the vertical guide groove 3.13. The spring 3.14 is located above the floating push plate 3.12. The floating push plate 3.12 moves downward along the vertical guide groove 3.13 under the action of the spring 3.14 and its own weight until the ball 3.15 is supported on the upper surface of the main conveyor belt 1. In this way, when there is no obstacle between the floating push plate 3.12 and the main conveyor belt 1, the floating push plate 3.12 can be ensured to move downward along the vertical guide groove 3.13 under the action of the spring 3.14 and its own weight until the ball 3.15 is supported on the upper surface of the main conveyor belt 1, thereby effectively controlling the gap between the push plate 3.1 and the main conveyor belt 1 to be kept at a sufficiently small level.

[0055] Specific embodiment 4: The rest of the structure of this embodiment refers to specific embodiment 3, except that: like Figure 2 , Figure 3 As shown, the squid pushing mechanism 3 also includes a roller 3.6, a side baffle 3.4, a magnet 3.5 and an elastic element. The roller 3.6 is fixedly arranged on the frame (the fixed arrangement here means that the position of the roller 3.6 is fixed), and the roller 3.6 can rotate. The roller 3.6 and the limit block 3.3 are located on the same side of the push plate 3.1.

[0056] The side baffle 3.4 is hinged on the side of the push plate 3.1 away from the input end of the main conveyor belt 1. In this embodiment, the side baffle 3.4 is hinged on the side of the main push plate 3.11 away from the input end of the main conveyor belt 1. The side of the side baffle 3.4 is vertically distributed. A driving inclined surface 3.7 cooperating with the roller 3.6 is provided on one side of the side baffle 3.4. In this embodiment, the driving inclined surface 3.7 and the roller 3.6 are located on the same side of the push plate 3.1.

[0057] The magnet 3.5 is fixed on the push plate 3.1. The magnet 3.5 and the limit block 3.3 are located on opposite sides of the push plate 3.1. The magnet 3.5 is close to the side baffle 3.4. The magnet 3.5 is used to adsorb and fix the side baffle 3.4 on the push plate 3.1. The magnet 3.5 in this embodiment is a strong magnet 3.5.

[0058] In this embodiment, the elastic element is a torsion spring. The elastic element provides elastic force to rotate the side baffle 3.4 toward the magnet 3.5 until the side baffle 3.4 abuts against the magnet 3.5. At this time, the side baffle 3.4 is adsorbed and fixed on the magnet 3.5, and the side baffle 3.4 is perpendicular to the push plate 3.1. The adsorption force between the magnet 3.5 and the side baffle 3.4 is much greater than the elastic force provided by the elastic element. In this embodiment, the elastic force provided by the elastic element is 0.5 to 1N.

[0059] Before the push plate 3.1 is pushed out (ie the push plate 3.1 abuts against the limit block 3.3), the driving inclined surface 3.7 abuts against the roller 3.6, and at this time, the side baffle 3.4 is separated from the magnet 3.5.

[0060] When the push drive mechanism 3.2 pushes the push plate 3.1 out, when the roller 3.6 separates from the driving slope 3.7, the side baffle 3.4 abuts against the magnet 3.5 under the action of the elastic element. At this time, the side baffle 3.4 is adsorbed and fixed on the magnet 3.5, and the side baffle 3.4 is perpendicular to the push plate 3.1.

[0061] When the push drive mechanism 3.2 drives the push plate 3.1 to move back and reset, the inclined surface will abut against the roller 3.6 and drive the side baffle 3.4 to rotate away from the input end of the main conveyor belt 1, so that the side baffle 3.4 is separated from the magnet 3.5.

[0062] During the process of the squid pushing mechanism 3 pushing the squids transported on the main conveyor belt 1 to the corresponding grading conveyor belt 2; especially when the squid feet are clamped between the push plate 3.1 and the upper surface of the main conveyor belt 1, during the process of the push plate 3.1 moving back, in order to prevent the squids on the main conveyor belt 1 from being transported backward and detached from the push plate 3.1, the present solution provides a side baffle 3.4 on the side of the push plate 3.1 away from the input end of the main conveyor belt 1, so that the push plate 3.1 can push the squids transported on the main conveyor belt 1 to the corresponding grading conveyor belt 2. However, in this case, before the push plate 3.1 is pushed out, the squid may be blocked by the side baffle 3.4 on a squid pushing mechanism 3, resulting in the squid being unable to be smoothly transmitted to the designated squid pushing mechanism 3. In order to solve this problem, the present solution improves the squid pushing mechanism 3. Before the push plate 3.1 is pushed out, the driving inclined surface 3.7 is against the roller 3.6. At this time, the side baffle 3.4 is separated from the magnet 3.5. If the squid is blocked by the side baffle 3.4 on a squid pushing mechanism 3, the squid will overcome the force of the elastic element, causing the side baffle 3.4 to rotate, and then pass over the side baffle 3.4 and continue to be transmitted to the designated squid pushing mechanism 3.

[0063] When the push drive mechanism 3.2 pushes the push plate 3.1 out, when the roller 3.6 separates from the driving inclined surface 3.7, the side baffle 3.4 abuts against the magnet 3.5 under the action of the elastic element. At this time, the side baffle 3.4 is adsorbed and fixed on the magnet 3.5; the adsorption of the magnet 3.5 is large enough to keep the side baffle 3.4 fixed and not rotate. Therefore, when the push plate 3.1 pushes the squids transported on the main conveyor belt 1 to the corresponding grading conveyor belt 2, the side baffle 3.4 can prevent the squids on the main conveyor belt 1 from being transported backward and separated from the push plate 3.1, so that the push plate 3.1 can push the squids transported on the main conveyor belt 1 to the corresponding grading conveyor belt 2.

[0064] 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.
