Abstract
Description
Technical Field
[0001] This utility model relates to the field of shrimp screening technology, specifically a shrimp screening device for aquaculture. Background Technology
[0002] In the aquaculture industry, shrimp selection is a crucial step in ensuring both farming efficiency and product quality. By sorting shrimp into different categories according to size, their market value is increased.
[0003] Currently, when screening farmed shrimp, a vibrating screen structure is used to sieve the shrimp, with smaller shrimp passing through and larger ones remaining at the top. However, in practice, because the screen size is fixed, it can only screen shrimp of a fixed size. If the screen size needs to be changed, the screen itself must be replaced, which is inconvenient. Therefore, an improved shrimp screening device is needed to solve these problems. Utility Model Content

[0010] Preferably, the sliding frame has a groove on its right side, and the left side of the first discharge groove is slidably installed inside the groove, so that the sliding frame can slide outside the first discharge groove.
[0011] Preferably, the screening assembly includes a crossbar, which is fixedly installed on the inner side of the sliding frame near the bottom. A screening rod is provided inside the sliding frame, and fixing bolts are threaded on both the left and right ends of the screening rod to facilitate adjustment of the spacing of the screening rod and screening of shrimp of different sizes.
[0012] Preferably, the sliding frame has through slots on both the left and right sides, and the width of the through slots is the same as the diameter of the screening rod. The screening rod passes through the through slots, and the two fixing bolts are located on the left and right sides of the sliding frame, so as to facilitate the fixed installation of the screening rod in the sliding frame.

[0014] Preferably, the second discharge trough is located below the first discharge trough, and the discharge direction of the second discharge trough is opposite to that of the first discharge trough, which facilitates the discharge of two different sizes of shrimp from two directions.
[0015] Compared with the prior art, this utility model provides a shrimp screening device for aquaculture, which has the following beneficial effects:
[0016] 1. This aquaculture shrimp screening device, through its screening components, allows for the screening of shrimp of different sizes by adjusting the spacing between the screening rods during use. Simultaneously, the first motor drives the sliding frame to reciprocate, screening the shrimp on the screening rods within the sliding frame. Larger shrimp remain on the screening rods and are discharged through the first discharge chute, while smaller shrimp pass through the screening rods and fall onto the conveyor belt below.
[0017] 2. This aquaculture shrimp screening device, through its discharge mechanism, uses a second motor to drive a conveyor belt downwards during operation, which transports the shrimp that fall onto the conveyor belt downwards, allowing the conveyor belt to discharge small-sized shrimp through the second discharge chute.

A fixing block 417 is fixedly mounted on the outer side of the side plate 3 near the right end. A fixing spring 418 is fixedly mounted between the fixing block 417 and the connecting block 416. A first discharge chute 419 is fixedly mounted between the two side plates 3 to facilitate the reciprocating motion of the sliding frame 411, so that the screening rod 422 can screen the shrimp.
[0033] Furthermore, a through groove is provided at the corresponding position of the side plate 3 and the sliding frame 411. The front and back of the sliding frame 411 are provided with protruding structures, and the protruding structures are slidably installed inside the through groove, so that the sliding frame 411 can slide in the middle of the side plate 3.
[0034] Furthermore, the side plate 3 of the roller 415 has a groove, and the cam 414 contacts the groove of the roller 415, so that the cam 414 can cooperate with the roller 415 to drive the sliding frame 411 to slide.
[0035] Furthermore, a groove is provided on the right side of the sliding frame 411, and the left side of the first discharge groove 419 is slidably installed inside the groove, so that the sliding frame 411 can slide outside the first discharge groove 419.
[0036] Furthermore, the screening assembly 42 includes a crossbar 421, which is fixedly installed on the inner side of the sliding frame 411 near the bottom. The sliding frame 411 is provided with a screening rod 422, and both the left and right ends of the screening rod 422 are threaded with fixing bolts 423 to facilitate adjustment of the spacing of the screening rod 422 for screening shrimp of different sizes.
[0037] Furthermore, through slots are provided on both the left and right sides of the sliding frame 411, and the width of the through slots is the same as the diameter of the screening rod 422. The screening rod 422 passes through the through slots, and two fixing bolts 423 are located on the left and right sides of the sliding frame 411, so that the screening rod 422 can be fixedly installed in the sliding frame 411.
[0038] Example 2:
[0039] To facilitate the discharge of small-sized shrimp, this invention provides another embodiment; please refer to [link / reference needed]. Figure 7 Furthermore, in conjunction with Embodiment 1, the discharge mechanism 5 includes a second motor 51, which is fixedly installed on the front side plate 3. An active roller 52 is fixedly installed at the output end of the second motor 51. A driven roller 53 is rotatably installed between the two side plates 3. A conveyor belt 54 is driven between the active roller 52 and the driven roller 53. A second discharge trough 55 is fixedly installed between the two side plates 3 to facilitate the discharge of small-volume shrimp.
[0040] Furthermore, the second discharge chute 55 is located below the first discharge chute 419, and the discharge direction of the second discharge chute 55 is opposite to that of the first discharge chute 419, which facilitates the discharge of two different sizes of shrimp from two directions.
[0041] In actual operation, when this device is used, the screening rod 422 is inserted into the sliding frame 411 and placed on the crossbar 421. Then, the fixing bolt 423 is screwed into both ends of the screening rod 422, and multiple screening rods 422 are installed in the sliding frame 411. After adjusting the spacing between adjacent screening rods 422 to a suitable level, the fixing bolt 423 is tightened.
[0042] Shrimp are poured into the upper left side of the sliding frame 411. The first motor 413 drives the cam 414 to rotate, which in turn drives the sliding frame 411 to slide on the side plate 3 in conjunction with the roller 415. With the pull of the fixed spring 418, the sliding frame 411 slides back and forth, causing the screening rod 422 in the sliding frame 411 to screen the shrimp. Large shrimp are left above the screening rod 422, while small shrimp fall onto the conveyor belt 54 through the screening rod 422. The shrimp left on the screening rod 422 are discharged through the first discharge chute 419 on the right side of the screening rod 422. The second motor 51 drives the drive roller 52 to rotate, which in turn drives the conveyor belt 54 through the driven roller 53 to transport the small shrimp downwards. The small shrimp are then discharged from the second discharge chute 55 in the opposite direction.
