Description

Technical Field

[0001] This utility model belongs to the field of grading and screening technology, specifically relating to an airflow suspension grading and screening machine for small fish and shrimp. Background Technology

[0002] In the aquaculture and processing sector, the grading and sorting of small fish and shrimp is crucial. Different sizes of small fish and shrimp have significantly different market prices and processing methods when sold. Precise grading and sorting can increase product added value and improve processing efficiency.

[0003] Currently, the grading and sorting technology for small fish and shrimp faces numerous challenges. Traditional manual sorting methods rely primarily on human experience and simple tools, such as sieves with different aperture sizes, to individually identify and classify small fish and shrimp. This method is extremely inefficient, labor-intensive, and highly susceptible to subjective factors, making it difficult to standardize grading criteria and easily leading to inaccurate grading. Moreover, with the increasing production of small fish and shrimp, manual sorting is increasingly unable to meet the needs of large-scale production. While existing mechanical sorting equipment has improved efficiency to some extent, it still has significant shortcomings. Some sorting machines based on a combination of mechanical vibration and sieves achieve grading by moving small fish and shrimp across sieves with different aperture sizes through vibration. However, small fish and shrimp are irregularly shaped and soft in texture, making them easily injured during vibration and friction with the sieves, affecting product quality and survival rate. This is especially true for the fragile shells and appendages of shrimp and the delicate body surfaces of small fish. Furthermore, for individuals of similar size and unique shapes, this type of equipment has poor sorting accuracy and is prone to missorting and omissions.

[0004] Therefore, there is a need for an airflow suspension grading and screening machine for small fish and shrimp to solve the problems of low efficiency of manual screening methods and the impact of mechanical vibration and screen combination on product quality and survival rate in existing technologies.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4 This utility model provides a small fish and shrimp airflow suspension grading and screening machine, including a box 1, an air outlet 2, a conveyor belt 3, a partition 4, a baffle mechanism 5, a collection mechanism 6, and a controller 7. An air box is provided on the rear side of the inside of the box 1. The air outlet 2 is uniformly and fixedly connected to the top of the air box. The conveyor belt 3 is located on the top of the box 1. The partition 4 is fixedly connected to the top of the conveyor belt 3. The baffle mechanism 5 is uniformly arranged on the front side of the conveyor belt 3. The collection mechanism 6 is located below the baffle mechanism 5. The controller 7 is fixedly connected to the left side of the box 1.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the surface of the conveyor belt 3 is provided with flexible protrusions, which are made of rubber material.

[0025] The flexible protrusions increase friction without damaging small fish and shrimp.

[0026] Further as Figure 1, Figure 2 and Figure 3 As shown, it is worth noting that the partition mechanism 5 consists of a fixed frame 501, a pull-out plate 502, a handle 503, and a buffer layer 504. The fixed frame 501 is fixedly connected to the top of the box 1, the pull-out plate 502 is slidably connected to the front side of the inside of the fixed frame 501, the handle 503 is fixedly connected to the top of the pull-out plate 502, and the buffer layer 504 is respectively provided on the inner wall of the fixed frame 501 and the back of the pull-out plate 502.

[0027] By adjusting the position of the pull-out plate 502, the pull-out plate 502 can be slid, making it easy to open the fixed frame 501 and clean the impurities above the internal filter screen 606.

[0028] As can be seen from the above working process, the bellows, air outlet 2, conveyor belt 3 and baffle mechanism 5 can be set up to achieve accurate grading and screening of small fish and shrimp according to their size and weight. The buffer layer 504 can reduce the impact of collisions on small fish and shrimp during the screening and collection process, effectively protect the integrity of small fish and shrimp, improve product quality and meet different production needs.

[0029] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the collection mechanism 6 consists of a door 602, a second buffer layer 603, a mounting frame 604, a slide bar 605, a filter screen 606, a connecting rod 608, a pressure block 609, a push-pull plate 610, and a spring 611. The front of the box body 1 has a collection chamber 601. The door 602 is hinged to the front of the collection chamber 601. The second buffer layer 603 is set on the inner wall of the collection chamber 601. The mounting frame 604 is set on the upper part of the inside of the collection chamber 601.

[0030] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the slider 605 is symmetrically fixedly connected to the left and right sides of the mounting frame 604, and the inner wall of the collection cavity 601 is provided with a groove that matches the slider 605.

[0031] The slide bar 605 slides inside the slide groove, making it easy for the mounting frame 604 to be pulled out from inside the collection cavity 601.

[0032] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth noting that the filter 606 is disposed inside the mounting frame 604. The front and rear inner walls of the mounting frame 604 are symmetrically provided with storage grooves 607. The connecting rod 608 is slidably connected between the storage groove 607 and the outer surface of the mounting frame 604. The push-pull plate 610 is fixedly connected to the front side of the connecting rod 608. The front of the mounting frame 604 is provided with a groove for the push-pull plate 610 to be stored. The pressure block 609 is fixedly connected to the rear end of the connecting rod 608. The spring 611 is fixedly connected between the pressure block 609 and the side of the storage groove 607. The spring 611 is sleeved on the outside of the connecting rod 608. The top surface of the pressure block 609 is provided with an inclined surface. The distance between the bottom surface of the pressure block 609 and the inner bottom surface of the mounting frame 604 is adapted to the thickness of the filter 606.

[0033] The sloping design of the top surface of the pressure block 609 facilitates the smooth entry of the filter screen 606 into the mounting frame 604, and the distance between the bottom surface of the pressure block 609 and the inner bottom surface of the mounting frame 604 is adapted to the thickness of the filter screen 606, so that the filter screen 606 can be pressed and fixed.

[0034] This solution has the following working process: When in use, the device is first started by the controller 7, the bellows starts to work, and the airflow is blown out evenly from the air outlet 2. The airflow intensity of the air outlet 2 is different from left to right, which is used to blow small fish and shrimp of different weights. At the same time, the conveyor belt 3 starts to run. The small fish and shrimp to be screened are placed on the conveyor belt 3. The flexible protrusions on the surface of the conveyor belt 3 increase the friction between the small fish and shrimp and prevent them from slipping during the conveying process. At the same time, the flexible rubber material will not damage the small fish and shrimp.

[0035] During the operation of conveyor belt 3, the airflow from the bellows moves the small fish and shrimp forward. When they reach the position of the baffle mechanism 5, they come into contact with the internal buffer layer 504 and fall into the collection mechanism 6 below. The buffer layer 504 can reduce the impact force when the small fish and shrimp collide with the baffle mechanism 5, avoiding damage. Small fish and shrimp of different weights can fall into different collection chambers 601. The filter screen 606 that comes into contact with the collection chamber 601 can filter the small fish and shrimp again to prevent impurities from entering. Then the small fish and shrimp fall into the collection chamber 601. Then the box door 602 can be opened to take out the graded and screened small fish and shrimp.

[0036] When the filter 606 needs to be cleaned or replaced, pull the mounting frame 604 forward. It slides inside the groove via the slide bar 605, making it easy for the mounting frame 604 to be pulled out from inside the collection chamber 601. Then pull the push-pull plate 610 forward. The connecting rod 608 drives the pressure block 609 forward, compressing the spring 611 and causing the pressure block 609 to leave the filter 606. At this time, the filter 606 can be removed from the mounting frame 604. When installing the filter 606, put the filter 606 into the mounting frame 604, release the push-pull plate 610, and the spring 611 returns to its original deformation, pushing the pressure block 609 backward. The inclined surface design of the top surface of the pressure block 609 makes it easy for the filter 606 to enter the mounting frame 604 smoothly. The distance between the bottom surface of the pressure block 609 and the bottom surface inside the mounting frame 604 is adapted to the thickness of the filter 606, which can press and fix the filter 606.

[0037] In summary: The system, with its bellows, air outlet 2, conveyor belt 3, and baffle mechanism 5, enables precise grading and screening of small fish and shrimp based on their size and weight. The buffer layer 504 reduces the impact of collisions during screening and collection, effectively protecting the integrity of the fish and shrimp, improving product quality, and meeting diverse production needs. The collection mechanism 6 further filters impurities from the fish and shrimp, and the filter screen 606 is easy to install and remove, allowing for convenient replacement according to actual usage requirements, ensuring screening effectiveness, and enhancing the applicability and flexibility of the equipment.
