Description

Technical Field

[0001] This utility model belongs to the field of granulator technology, and specifically relates to a granulator for biological feed used in crab seedling farming. Background Technology

[0002] A pellet mill for crab larvae farming is a mechanical device specifically designed to process the biological feed (such as algae, zooplankton, microorganisms, etc.) required for crab larvae farming into pelleted feed. Biological feed is usually produced using catalysis to optimize the nutritional composition of the feed. Catalysis is achieved by adding catalysts (such as enzymes, microorganisms, ions, etc.) to accelerate the chemical reactions or biological conversion efficiency in the production process of biological feed.

[0003] Traditional feed pellet mills typically use extrusion to extrude feed into long strips of pellets. This method results in uneven pellets and difficulty in controlling their length, leading to feed that is too long or too short. This makes it difficult to determine the dosage during subsequent farming, resulting in feed waste or insufficient feed usage, thus reducing the farming effect of crab seedlings. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a biological feed pelleting machine for crab seedling farming, which can cut the extruded strips into uniform small segments.

[0005] This utility model is achieved through the following technical solution: A biological feed pelleting machine for crab larvae farming includes a first "U"-shaped support, a second "U"-shaped support, a pelleting barrel, and a storage barrel; The first "U"-shaped support has a granulation barrel at the top center, and the top two sides of the first "U"-shaped support are connected to the bottom two ends of the second "U"-shaped support, with the second "U"-shaped support located directly above the granulation barrel. The second "U"-shaped support is equipped with a first electric telescopic rod at the top. The extended end of the first electric telescopic rod passes through the main body of the second "U"-shaped support and is located inside the granulation barrel. The extended end of the first electric telescopic rod is fixedly connected to an installation plate, and a pressure plate is bolted to the bottom of the installation plate. The pressure plate is matched with the diameter of the granulation barrel. The granulation barrel has its body passing through and fixedly connected to the top main body of the first "U"-shaped support. The bottom outlet of the granulation barrel is provided with an extrusion hole plate, and the extrusion hole plate has several discharge holes. On one side of the granulation barrel, on the bottom main body of the first "U"-shaped support, there is an "L"-shaped plate and a support plate. The bottom of the "L"-shaped plate is movably connected to an arc-shaped cutting blade through a rotating shaft. The main body of the support plate is fixedly connected to a second electric telescopic rod. The tail of the arc-shaped cutting blade is fixed with a guide rod that is hinged to the extended end of the second electric telescopic rod. The storage hopper is located below the granulation hopper.

[0006] The working principle of this utility model is as follows: In use, the bait is first accelerated to mature by adding catalysts (such as enzymes, microorganisms, ions, etc.). Then, the matured bait is placed into the pelleting tank. After the addition is completed, the first electric telescopic rod is activated to drive the pressure plate to extrude the bait from the pelleting tank into the extrusion hole plate. The bait will be extruded from the extrusion hole plate and form long strips. At the same time, the second electric telescopic rod is activated to drive the guide rod to reciprocate, so that the arc-shaped cutting blade reciprocates at the bottom of the pelleting tank to cut the long strips of bait. The cut bait forms uniform small segments and falls into the storage cylinder, thus completing the pelleting process.

[0007] As a further improvement of this utility model, the guide rod has a hollowed-out guide groove in the middle, and the extended end of the second electric telescopic rod is fixedly connected with a circular sliding rod that matches the guide groove.

[0008] The circular sliding rod connects to the guide groove, and the reciprocating extension and retraction of the second electric telescopic rod drives the guide rod to reciprocate, which in turn drives the arc-shaped cutting blade to cut the long bait into segments. The sleeved circular sliding rod and guide groove facilitate installation and disassembly, and are convenient for later maintenance.

[0009] As a further improvement of this utility model, a support seat is fixedly provided on one side of the first "U"-shaped bracket for placing the unblocking disc; the top of the support seat is arc-shaped, and a limiting plate is provided in the middle of the top for engaging the unblocking disc; the top of the unblocking disc is provided with bolts that connect to the mounting plate, and the bottom is provided with a punch rod that matches the discharge hole provided on the extrusion hole plate.

[0010] After the biological bait in the pelleting tank is pelleted, some bait will become stuck in the discharge hole of the extrusion perforated plate. At this time, the pressure plate is removed from the mounting plate, and then the unblocking disc is installed. The unblocking disc is pressed against the extrusion perforated plate by the first electric telescopic rod, and the material in the discharge hole of the extrusion perforated plate is pushed out by the chuck at the bottom of the unblocking disc. The unblocking disc is installed on the side of the first "U"-shaped bracket by the support base and is locked by the limiting plate for easy fixing and removal, improving the efficiency of unblocking after bait pelleting.

[0011] As a further improvement of this utility model, the side of the first "U"-shaped bracket is provided with an "L"-shaped support plate above the support base, and a magnet is fixed on the surface of the "L"-shaped support plate.

[0012] The unblocking disc is further secured with magnets to improve its stability during placement.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves uniform granulation by installing an arc-shaped cutting blade at the bottom of the granulation tank and using the reciprocating motion of an electric telescopic rod to drive the arc-shaped cutting blade to repeatedly cut the bait into uniform small segments. The use of an electric telescopic rod enables automated, rapid, and uniform cutting of the bait, improving granulation efficiency.

[0014] 2. In this utility model, the unblocking disc is placed on the side of the first "U"-shaped bracket and secured by the limiting plate of the support base, making it easy to pick up and facilitate the later unblocking of the extrusion hole plate. At the same time, magnets are used to further fix the top of the unblocking disc, further improving its stability during placement. Attached Figure Description

The top two sides of the first "U"-shaped support 1 are connected to the bottom two ends of the second "U"-shaped support 2, and the second "U"-shaped support 2 is located directly above the granulation barrel 3. The second "U"-shaped support 2 is provided with a first electric telescopic rod 5 at the top. The extended end of the first electric telescopic rod 5 passes through the main body of the second "U"-shaped support 2 and is located inside the granulation barrel 3. The extended end of the first electric telescopic rod 5 is fixedly connected to an installation plate 6. The bottom of the installation plate 6 is connected to a pressure plate 7 by bolts. The pressure plate 7 is matched with the diameter of the granulation barrel 3. like Figure 2-3 As shown, the granulation barrel 3 has its barrel body passing through and fixedly connected to the top main body of the first "U"-shaped support 1. The bottom outlet of the granulation barrel 3 is provided with an extrusion hole plate 23, and the extrusion hole plate 23 is provided with several discharge holes 21. On one side of the granulation barrel 3, located on the bottom main body of the first "U"-shaped support 1, there is an "L"-shaped plate 12 and a support plate 8. The bottom of the "L"-shaped plate 12 is movably connected to an arc-shaped cutting blade 10 through a rotating shaft 13. The support plate 8 is fixedly connected to a second electric telescopic rod 9. The tail of the arc-shaped cutting blade 10 is fixed with a guide rod 11, which is hinged to the extended end of the second electric telescopic rod 9. The storage tank 4 is located below the granulation tank 3.

[0022] The working principle of this embodiment is as follows: In use, the bait is first accelerated to mature by adding a catalyst (such as enzymes, microorganisms, ions, etc.). Then, the matured bait is placed into the pelleting tank 3. After the addition is completed, the first electric telescopic rod 5 is activated to drive the pressure plate 7 to squeeze the bait in the pelleting tank 3 into the extrusion hole plate 23. The bait will be squeezed out from the extrusion hole plate 23 and form a long strip. At the same time, the second electric telescopic rod 9 is activated to drive the guide rod 11 to reciprocate, so that the arc-shaped cutting blade 10 reciprocates at the bottom of the pelleting tank 3 to cut the long strip of bait. The cut bait forms uniform small segments and falls into the storage cylinder 4, thus completing the pelleting. Example

[0023] This embodiment is a further improvement based on Embodiment 1, as detailed below: like Figure 3 As shown, the guide rod 11 has a hollowed-out center to form a guide groove 15, and the extended end of the second electric telescopic rod 9 is fixedly connected to a circular slide rod 14 that matches the guide groove 15.

[0024] The working principle of this embodiment is the same as that of Embodiment 1. The circular slide rod 14 is sleeved with the guide groove 15, and the reciprocating extension and retraction of the second electric telescopic rod 9 drives the guide rod 11 to reciprocate, which in turn drives the arc-shaped cutting blade 10 to reciprocate and cut the long bait into segments. The sleeved circular slide rod 14 and guide groove 15 are easy to install and disassemble, and facilitate later maintenance. Example

[0026] The working principle of this embodiment is the same as that of embodiment 2. After the biological bait in the pelleting tank 3 is pelleted, some bait will be blocked in the discharge hole 21 of the extrusion perforated plate 23. At this time, the pressure plate 7 is removed from the mounting plate 6, and then the unblocking disc 16 is installed. The unblocking disc 16 is pressed against the extrusion perforated plate 23 by the first electric telescopic rod 5. The material in the discharge hole 21 on the extrusion perforated plate 23 is pushed out by the piercing rod 22 at the bottom of the unblocking disc 16. The unblocking disc 16 is installed on the side of the first "U" shaped bracket 1 by the support base 17 and is locked by the limiting plate 24, which facilitates fixing and removal and improves the unblocking efficiency after bait pelleting.
