[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic plants and animals under artificial control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding and management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive farming, intensive farming and high-density intensive farming. Extensive farming is to release seedlings in medium and small natural waters, and rely entirely on natural bait to grow aquatic products, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming is to grow aquatic products in smaller water bodies by feeding and fertilizing, such as fish farming in ponds, cage fish farming and fence farming. High-density intensive farming uses methods such as flowing water, temperature control, oxygenation and feeding high-quality bait to carry out high-density farming in small water bodies to obtain high yields, such as high-density flowing water farming of fish and shrimp. Aquaculture requires corresponding feed, which can make aquatic products not only rich in protein and vitamins but also high-yield to obtain huge profits.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1.

The two clamping blocks will clamp the connecting rod more tightly to ensure the stability of the connection between the connecting block and the clamping block.

[0023] 2. In the process of installing and docking the first sieve plate and the second sieve plate of the present invention, after the operating door is opened, the first sieve plate and the second sieve plate are moved into the installation shell through the operating port, and then the first sieve plate and the second sieve plate are respectively moved to the surfaces of the arc-shaped docking rods on both sides and move along the arc-shaped docking rods, and then the first sieve plate and the second sieve plate can be docked smoothly, which is conducive to the first sieve plate and the second sieve plate to be docked quickly and accurately, and the time required for docking is reduced. After the first sieve plate and the second sieve plate are docked, the clamping rod will contact the end of the first sieve plate, and the clamping block will move between the two arc-shaped docking rods. Then, the second sieve plate is pushed along the arc-shaped docking rod to the side close to the first sieve plate, and the clamping block at the bottom of the first sieve plate will be blocked by the arc-shaped docking rod. The clamping block will move to the side away from the first sieve plate under the action of the arc-shaped docking rod, and then the clamping block will dock with the clamping block, which is conducive to further simplifying the operation when the first sieve plate and the second sieve plate are docked, and the installation and docking can be performed more conveniently, reducing operating errors and reducing operating time.

[0024] 3. In the process of installing the first sieve plate and the second sieve plate of the present invention, after the bottom of the first sieve plate and the second sieve plate are connected, the upper ends of the first sieve plate and the second sieve plate need to be moved respectively between the mounting plates and the feeding pipe on both sides, and then when the bolts are screwed into the inside of the mounting plates, the bolts will pass through the waist-shaped grooves to limit the first sieve plate and the second sieve plate, and the arc-shaped baffle will contact the surface of the bolts.

A small swing under the restriction of the bolt is conducive to the rapid screening of the crushed raw materials, thereby improving the screening efficiency.

When the bolts are screwed into the side wall position of the feeding pipe, the liner is moved to the inside of the feeding pipe and fits with the side wall and the bottom of the feeding pipe, and then the bolts are tightened to install and fix the liner. The swing amplitude of the first screen plate and the second screen plate is limited by the bolts, and the extrusion block will not move to the trapezoidal groove position.

[0062] During the installation of the first sieve plate 15 and the second sieve plate 16, after the bottom of the first sieve plate 15 and the second sieve plate 16 are connected, the upper ends of the first sieve plate 15 and the second sieve plate 16 need to be moved respectively between the mounting plates 35 on both sides and the feeding pipe 3, and then when the bolts 36 are screwed into the mounting plates 35, the bolts 36 will pass through the waist-shaped grooves 37 to limit the first sieve plate 15 and the second sieve plate 16, and the arc-shaped baffle plates 38 will contact the surfaces of the bolts 36. Then, during the operation of the rotating shaft 6 and the crushing piece 10, the crushing piece 10 will cause the first sieve plate 15 and the second sieve plate 16 to shake during the crushing of the raw materials, and the first sieve plate 15 and the second sieve plate 16 will be at the waist. The first sieve plate 15 and the second sieve plate 16 are swung slightly under the restriction of the trapezoidal groove 37 and the bolt 36, which is conducive to the rapid screening of the crushed raw materials and improves the screening efficiency. The raw materials that are crushed to a certain extent can quickly pass through the first sieve plate 15 and the second sieve plate 16, thereby reducing the screening pressure of the first sieve plate 15 and the second sieve plate 16 during operation. When the bolt 36 is screwed into the side wall position of the feeding pipe 3, the liner 4 is moved to the inside of the feeding pipe 3 and fits with the side wall and the bottom of the feeding pipe 3, and then the bolt 36 is tightened to install and fix the liner 4. The swing amplitude of the first sieve plate 15 and the second sieve plate 16 is limited by the bolt 36, and the extrusion block 29 will not move to the position of the trapezoidal groove 28.

[0063] In the process of crushing the raw materials, the shaking amplitude of the first sieve plate 15 and the second sieve plate 16 cannot be adjusted. As a further solution of the present invention, a pressing plate 39 is slidably connected to the surface of the mounting plate 35, and a fastening rod 40 is threadedly connected to the surface of the pressing plate 39. The fastening rod 40 penetrates the pressing plate 39. A through groove 41 is provided on the surface of the mounting plate 35. After the fastening rod 40 passes through the through groove 41, it is rotatably connected to a limiting block 42. The limiting block 42 is used to limit the first sieve plate 15 and the second sieve plate 16.

[0064] During the installation of the first sieve plate 15 and the second sieve plate 16, the bolts 36 will pass through the waist-shaped grooves 37 on the surfaces of the first sieve plate 15 and the second sieve plate 16, and then the first sieve plate 15 and the second sieve plate 16 will be limited by adjusting the limit blocks 42 on both sides, so that the shaking amplitude of the first sieve plate 15 and the second sieve plate 16 during operation can be adjusted to improve the screening efficiency of different raw materials, and then the fastening rod 40 is rotated, the pressing plate 39 will move to the side close to the limit block 42, and then the pressing plate 39 and the limit block 42 will clamp the mounting plate 35 to fix the limit block 42.

[0065] In the process of crushing the raw materials, the friction between the first sieve plate 15 and the second sieve plate 16 when moving between the mounting plate 35 and the feeding pipe 3 is relatively large. As a further solution of the present invention, the mounting plate 35 is rotatably connected to a plurality of rolling columns 43 on one side thereof close to the first sieve plate 15 and the second sieve plate 16;

[0066] During the process of crushing the raw material, the first sieve plate 15 and the second sieve plate 16 will shake under the action of the rotating shaft 6, the crushing piece 10 and the raw material, and the first sieve plate 15 and the second sieve plate 16 will reciprocate between the mounting plate 35 and the feeding pipe 3, and the rolling column 43 will rotate to reduce the friction wheel of the first sieve plate 15 and the second sieve plate 16, thereby increasing the service life of the first sieve plate 15 and the second sieve plate 16 and ensuring the shaking amplitude of the first sieve plate 15 and the second sieve plate 16.
