Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sorting technology, and in particular relates to a sorting machine. Background Technology
[0002] A sorting machine is an automated device used for rapid sorting and classification. With the development of the seafood industry, crabs have become an important food and logistics commodity. However, traditional crab sorting methods mainly rely on manual operation, which is not only inefficient but also prone to sorting errors. In order to improve sorting efficiency and accuracy, automated sorting technology has gradually attracted attention. To meet this need, a sorting machine is now used to automate the sorting of crabs.
[0003] However, existing sorting machines rely on conveyor belts to move crabs when sorting them. After identification, the system moves the crabs to designated collection baskets via a movable arm. During the movement, the crabs come into direct contact with and collide with the movable arm, which can cause some crabs to break or be damaged, thus affecting the quality of the crabs. Utility Model Content
[0004] This invention addresses the problem in existing sorting machines where crabs are moved via conveyor belts after identification. The system uses a movable arm to slide the crabs into designated collection baskets, but the crabs' direct contact and impact with the arm during movement can cause some to break or be damaged, thus affecting the crab quality. The following technical solution is proposed:
[0005] A sorting machine includes a fixed frame, a conveyor belt fixedly installed inside the top of the fixed frame, multiple first feeding plates fixedly connected to both sides of the fixed frame, a second feeding plate fixedly connected to one end of the fixed frame, a movable rod rotatably connected inside the fixed frame at a position on the side of the first feeding plate, a movable arm fixedly connected to one end of the movable rod, multiple airbags connected inside the movable arm, a squeezing block movably connected inside the movable arm at a position outside the airbags, limit blocks fixedly connected to both ends of the squeezing block, the outer surface of the limit blocks movably connected to the inside of the movable arm, and memory foam fixedly connected to the end of the squeezing block away from the airbags.
[0006] Preferably, multiple cylinders are fixedly connected to the bottom ends of both the first and second feeding plates, and springs are fixedly connected to the bottom ends of the multiple cylinders. A rubber plate is fixedly connected between the bottom ends of the multiple springs, and an auxiliary rod is fixedly connected to the top end of the rubber plate. The multiple auxiliary rods are respectively movably connected inside the first and second feeding plates.
[0007] Preferably, the horizontal height of the bottom end of the movable arm is higher than the horizontal height of the top end of the conveyor belt.
[0008] Preferably, the airbag is spherical in shape, and the outer surface of the airbag is in contact with one end face of the compression block.
[0009] Preferably, a limiting groove is formed inside the movable arm at a position corresponding to the outer surface of the limiting block, and the outer surface of the limiting block is slidably connected to the inside of the limiting groove.
[0010] Preferably, the auxiliary rod consists of two parts: a top limiting post and a bottom positioning post.
[0011] The beneficial effects of this utility model are as follows:
[0012] (1) It can automatically perform secondary buffering for crabs, effectively preventing crabs from being damaged when they directly hit the moving arm, thereby improving the protection of crabs and ensuring that the quality of crabs is not affected.
[0013] (2) It can effectively buffer the impact force when the crab directly hits the collection basket due to gravity, and avoid the crab from being lost due to direct impact on the collection basket, which greatly affects the quality of the crab. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0020] Example 1: This utility model provides a sorting machine, such as... Figures 1 to 2As shown, the device includes a fixed frame 1, a conveyor belt 2 fixedly installed inside the top of the fixed frame 1, a control console at one end of the fixed frame 1, a conveyor belt below the control console, a control panel fixedly connected to the front of the control console, a camera at the bottom of the control console, multiple first feeding plates 3 fixedly connected to both sides of the fixed frame 1, a second feeding plate 4 fixedly connected to one end of the fixed frame 1, a movable rod 5 rotatably connected inside the fixed frame 1 at the side position of the first feeding plate 3, a motor fixedly connected to the bottom of the movable rod 5, the motor being electrically connected to the control panel, the bottom of the motor being fixedly installed inside the fixed frame 1, a movable arm 6 fixedly connected to one end of the movable rod 5, multiple airbags 7 connected inside the movable arm 6, a squeezing block 8 movably connected inside the movable arm 6 at the position outside the airbags 7, limit blocks 9 fixedly connected to both ends of the squeezing block 8, the outer surface of the limit blocks 9 movably connected to the inside of the movable arm 6, and memory foam 10 fixedly connected to the end of the squeezing block 8 away from the airbags 7.
[0021] like Figure 1 and Figure 3 As shown, multiple cylinders 11 are fixedly connected to the bottom ends of both the first feeding plate 3 and the second feeding plate 4. Springs 12 are fixedly connected to the bottom ends of each cylinder 11. Rubber plates 13 are fixedly connected between the bottom ends of the springs 12. Auxiliary rods 14 are fixedly connected to the top of the rubber plates 13. Multiple auxiliary rods 14 are movably connected inside the first feeding plate 3 and the second feeding plate 4, respectively. Then, the movable arm 6 rotates 90° under the drive of the motor. The movement of the movable arm 6 causes the crab to move synchronously, bringing the crab into the first feeding plate 3. The crab falls along the inside of the first feeding plate 3. The falling crab will contact and impact the rubber plate 13, which will exert a force on the spring 12, causing the spring 12 to deform and thus move the rubber plate 13 downward. The downward movement of the rubber plate 13 will cause the auxiliary rod 14 to slide synchronously inside the first feeding plate 3. The downward movement of the rubber plate 13 will also cause the crab to move downward synchronously, and then slide along the surface of the rubber plate 13 into the collection basket. This can effectively buffer the impact force when the crab directly hits the collection basket due to gravity, avoiding the loss of crabs caused by direct impact with the collection basket, which would greatly affect the quality of the crabs.
[0022] like Figure 1 and Figure 2 As shown, the bottom of the movable arm 6 is at a higher level than the top of the conveyor belt 2 to prevent the movable arm 6 from hitting the conveyor belt 2 when it moves, thus ensuring that the movable arm 6 can work normally.
[0023] like Figure 1 and Figure 2As shown, the airbag 7 is spherical in shape, and its outer surface is in contact with one end face of the compression block 8. When the crab applies force to the compression block 8, the compression block 8 applies force to the airbag 7, causing the airbag 7 to deform. This causes the compression block 8 to move the limiting block 9 toward the airbag 7. At this time, the compression block 8 and the airbag 7 work together to cushion the crab, which can automatically cushion the crab and improve its protection.
[0024] like Figure 1 and Figure 2 As shown, a limiting groove is provided inside the movable arm 6 at the position corresponding to the outer surface of the limiting block 9. The outer surface of the limiting block 9 is slidably connected to the inside of the limiting groove. The limiting block 9 can prevent the position of the extrusion block 8 from shifting when it moves, thus improving the stability of the extrusion block 8 when it moves.
[0025] like Figure 1 and Figure 4 As shown, the auxiliary rod 14 consists of two parts: a top limiting post and a bottom positioning rod. Since the diameter of the limiting post is larger than the diameter of the positioning rod, the limiting post plays a limiting role on the auxiliary rod 14.
[0026] Working Principle: In actual use, when sorting crabs is required, the crabs are first placed at the top of the conveyor belt. The conveyor belt transports the crabs to the area below the camera on the control panel. The camera captures images in real time and identifies the size of the crabs. The control panel then analyzes the images to determine which collection basket the crab belongs to. The conveyor belt then continues to move the crabs to the top of conveyor belt 2. When the crabs reach the designated collection basket, the control panel starts the motor. The motor's output rotates, causing the movable rod 5 to rotate synchronously. The rotation of the movable rod 5 then drives the movable rod... The movable arm 6 rotates synchronously. As the movable arm 6 rotates 90°, the crab will come into contact with and squeeze the memory foam 10. The memory foam 10 can provide initial cushioning for the crab. Then, the crab applies force to the squeezing block 8, and the squeezing block 8 applies force to the airbag 7, causing the airbag 7 to deform. This causes the squeezing block 8 to drive the limiting block 9 to move towards the airbag 7. At this time, the squeezing block 8 and the airbag 7 work together to provide secondary cushioning for the crab. This can automatically achieve secondary cushioning for the crab, effectively preventing the crab from being damaged when it directly hits the movable arm 6, thereby improving the crab's protection and ensuring that the crab's quality is not affected.
[0027] Then, the movable arm 6 rotates 90° under the drive of the motor. The movement of the movable arm 6 causes the crab to move synchronously, bringing the crab into the first feeding plate 3. The crab falls along the inside of the first feeding plate 3. As the crab falls, it contacts and impacts the rubber plate 13. The rubber plate 13 exerts a force on the spring 12, causing the spring 12 to deform, thereby driving the rubber plate 13 to move downward. The downward movement of the rubber plate 13 causes the auxiliary rod 14 to slide synchronously inside the first feeding plate 3. The downward movement of the rubber plate 13 will cause the crab to move downward synchronously. Then, it slides along the surface of the rubber plate 13 into the collection basket. This can effectively buffer the impact force when the crab directly hits the collection basket due to gravity, avoiding the loss of crabs caused by direct impact with the collection basket, which greatly affects the quality of the crabs.
[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
