Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a grading and screening device for half-smooth tongue sole seedlings. Background Technology

[0002] Half-smooth tongue sole fry are the larvae of the large, benthic, warm-temperate fish, the half-smooth tongue sole. They are laterally compressed and long-tongue shaped with eyes located on the left side of their bodies. They grow rapidly and can reach marketable size in one year. They have delicious meat, high protein content, and are considered high-end economic fish. They are also highly adaptable and suitable for factory farming and pond aquaculture, with broad prospects for industrialization.

[0003] In the field of half-smooth tongue sole farming, traditional seedling grading methods rely heavily on manual operation. Staff can only rely on their long-accumulated experience and simple tools such as simple fish sieves to identify and classify seedlings one by one in an extremely meticulous and time-consuming manner. Especially in large-scale farming, large farms need to process tens of thousands of seedlings every day. Such a huge workload makes manual grading not only extremely slow and unable to keep up with the fast-paced farming, but also consumes a lot of manpower, which seriously restricts the improvement of overall farming efficiency and often causes the farming process to stagnate.

Figure 1-4 As shown: A grading and screening device for semi-smooth tongue sole seedlings includes a screening box 1, a feeding hopper 2, a screening component 3 and a collection component 4. The upper surface of the screening box 1 is provided with a feeding hole, and the outer wall of the screening box 1 is provided with a conveying hole. The feeding hopper 2 is connected to the upper surface of the screening box 1.

[0027] The screening component 3 includes a support plate 311, a sliding frame 312, and a sliding block 313. The support plate 311 is fixedly connected to the inner wall of the screening box 1. A sliding hole is provided on the upper surface of the support plate 311. The sliding frame 312 is slidably connected to the bottom of the support plate 311. The sliding block 313 is slidably connected to the inner wall of the sliding hole. The bottom of the sliding block 313 is fixedly connected to the upper surface of the sliding frame 312. A slide rail 314 is provided on the inner wall of the sliding frame 312. The slide rail 314 is fixedly connected to the inner wall of the sliding frame 312. A fixing frame 315 is provided on the inner wall of the slide rail 314. The fixing frame 315 is slidably connected to the inner wall of the slide rail 314. The bottom of the slide rail 314 is open... A second sliding hole is provided, and a screening box 316 is provided at the bottom of the fixed frame 315. The screening box 316 is fixedly connected to the bottom of the fixed frame 315. A screening hole is opened at the bottom of the screening box 316. A connecting rod 317 is provided on the inner wall of the second sliding hole. One end of the connecting rod 317 is slidably connected to the inner wall of the second sliding hole. The connecting rod 317 is adapted to the fixed frame 315. A first handle 318 is provided on the outer wall of the screening box 316. The first handle 318 is fixedly connected to the outer wall of the screening box 316. An electric telescopic rod 319 is provided on the outer wall of the screening box 1. The electric telescopic rod 319 is fixedly installed on the outer wall of the screening box 1. The telescopic end of the electric telescopic rod 319 is fixedly connected to the sliding frame 312.

[0028] Furthermore, in this embodiment, when grading and screening the fry of the tongue sole, the fry are first poured into the feed hopper 2 along with water. Under the action of gravity, the fry enter the screening box 1 along with the feed hopper 2 and finally fall into the screening box 316. At this time, the electric telescopic rod 319 is activated, and the electric telescopic rod 319 starts to work, pushing the sliding frame 312 to slide horizontally at the bottom of the support plate 311. During the movement of the sliding frame 312, the sliding block 313 installed inside it also slides synchronously on the inner wall of the sliding hole 312, ensuring the stability of the movement of the sliding frame 312. At the same time, the sliding frame 312 drives the screening box 316 to reciprocate left and right through the sliding rail 314 and the fixed frame 315 connected to it. During the continuous movement of the screening box 316... Smaller tongue sole fry will pass through the screening holes on the screening box 316 along with the water and fall to the next screening layer for further screening. When it is necessary to remove the tongue sole fry that have completed the screening in the screening box 316, first stop the operation of the electric telescopic rod 319 to stop the screening box 316 from moving. Then open the screening box 1 and pull the connecting rod 317 upward until one end of the connecting rod 317 slides completely out of the inner wall of the sliding hole 2. At this time, the handle 318 can be pulled. Under the action of the pulling force, the handle 318 drives the screening box 316 to slide. The screening box 316 then drives the fixed frame 315 fixedly connected to it to slide smoothly on the inner wall of the slide rail 314. Finally, the screening box 316 is removed from the equipment, and the seedling removal operation is completed. Example

[0029] Based on Example 1, a preferred embodiment of the grading and screening device for semi-smooth tongue sole seedlings provided by this utility model is as follows: Figure 1-4 As shown: The collection component 4 includes a backflow block 411, a second slide rail 412, and a collection box 413. The backflow block 411 is fixedly connected to the inner wall of the screening box 1. The second slide rail 412 is fixedly connected to the bottom of the inner wall of the screening box 1. A sliding groove is provided on the upper surface of the second slide rail 412. The collection box 413 is slidably connected to the inner wall of the second slide rail 412. A second handle 414 is provided on the outer wall of the collection box 413. The second handle 414 is fixedly connected to the outer wall of the collection box 413. A connecting frame 415 is provided on the outer wall of the collection box 413. The connecting frame 415 is fixedly connected to the outer wall of the collection box 413. A second sliding block 416 is provided on the inner wall of the connecting frame 415. The second sliding block 416 is slidably connected to the inner wall of the connecting frame 415. The second sliding block 416 is slidably connected to the inner wall of the sliding groove.

[0030] Furthermore, in this embodiment, after the fry of the tongue sole fall from the screening box 316 while drinking water, the water will fall onto the backflow block 411 and slide into the collection box 413. At this time, the second sliding block 416 can be moved up first. The second sliding block 416 slides on the inner wall of the connecting frame 415, so that the second sliding block 416 slides out from the inner wall of the sliding groove, releasing the restriction on the collection box 413. Then, the second handle 414 is pulled, and the second handle 414 drives the collection box 413 to slide out from the inner wall of the second slide rail 412.

[0031] When the larvae of the semi-smooth tongue sole fall from the screening box 316 with the water flow, they will land on the backflow block 411 and then slide down the backflow block 411 into the collection box 413. To remove the larvae from the collection box 413, the second sliding block 416 must first be pushed upward. The second sliding block 416 slides upward on the inner wall of the connecting frame 415 until it slides completely out of the inner wall of the sliding groove, thereby releasing the restriction on the collection box 413. At this time, the second handle 414 is pulled. Under the action of the pulling force, the second handle 414 drives the collection box 413 to slide along the inner wall of the second slide rail 412, and the collection box 413 is pulled out smoothly.

[0032] In use, first, pour the semi-smooth tongue sole fry and water into the feed hopper 2. Under the action of gravity, the semi-smooth tongue sole fry enter the screening box 1 along with the feed hopper 2 and finally fall into the screening box 316. At this time, start the electric telescopic rod 319. The electric telescopic rod 319 starts working and pushes the sliding frame 312 to slide horizontally at the bottom of the support plate 311. During the movement of the sliding frame 312, the sliding block 313 installed inside it also slides synchronously on the inner wall of the sliding hole 312 to ensure the stability of the movement of the sliding frame 312. Simultaneously, the sliding frame 312, through the connected slide rail 314 and fixed frame 315, drives the screening box 316 to reciprocate left and right. As the screening box 316 moves, smaller tongue sole fry, along with water, pass through the screening holes on the screening box 316 and fall to the next screening layer for further screening. When the tongue sole fry fall from the screening box 316 with the water flow, they land on the backflow block 411 and then slide down the backflow block 411 into the collection box 413. When needed... To remove the semi-smooth tongue sole seedlings that have completed the current layer of screening from the screening box 316, first stop the operation of the electric telescopic rod 319 to stop the screening box 316 from moving. Then open the screening box 1 and pull the connecting rod 317 upwards until one end of the connecting rod 317 slides completely out of the inner wall of the sliding hole 2. At this point, you can pull the handle 318. Under the pulling force, the handle 318 drives the screening box 316 to slide, and the screening box 316 in turn drives the fixed frame 315 fixedly connected to it, so that it slides smoothly along the inner wall of the slide rail 314. Using the sliding mechanism, the screening box 316 is finally removed from the equipment, completing the seedling removal operation. To remove the semi-smooth tongue sole seedlings from the collection box 413, the second sliding block 416 must first be pushed upward. The second sliding block 416 slides upward on the inner wall of the connecting frame 415 until it completely slides out from the inner wall of the sliding groove, thereby releasing the restriction on the collection box 413. At this time, the second handle 414 is pulled. Under the pulling force, the second handle 414 drives the collection box 413 to slide along the inner wall of the second slide rail 412, smoothly pulling out the collection box 413.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
