During the crab seedling farming process, in order to meet the growth needs of the crab seedlings, they need to be provided with biological bait. In order to facilitate the crab seedlings to eat, the biological bait is usually made into granules for use.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a granulating device for crab seedling breeding biological bait, comprising a storage shell 1, a cylinder 3 is symmetrically installed at the top of the storage shell 1 near the edges on both sides, the top of the cylinder 3 is fixedly connected to a connecting frame 31, the bottom of the connecting frame 31 is symmetrically fixedly connected to a connecting rod 32, the outer surface of the connecting rod 32 slides through the top of the storage shell 1 and extends to the bottom, a molding mechanism 4 is arranged between the bottom ends of the four connecting rods 32, the molding mechanism 4 comprises a lifting plate 401, the outer surface of the lifting plate 401 is arranged near the middle area with molding holes 402, the top of the lifting plate 401 is fixedly connected to a first mounting block 403 near the front center, An electric push rod 404 is installed on the rear surface of the first mounting block 403, and a connecting block 405 is fixedly connected to the rear end of the electric push rod 404, and a U-shaped frame 406 is fixedly connected to the rear surface of the connecting block 405. A plurality of tool holders 407 are fixedly arranged between the inner walls of the U-shaped frame 406 at equal intervals. A feeding port 12 is fixedly connected to the outer surface of one side of the material storage shell 1, and a hydraulic cylinder 2 is fixedly installed at the top center of the material storage shell 1. The telescopic end of the hydraulic cylinder 2 slides through the top of the material storage shell 1 and extends to the bottom. A pressing plate 21 is fixedly connected to the bottom end of the hydraulic cylinder 2, and the outer surface of the pressing plate 21 is in contact with the inner wall of the material storage shell 1, and the outer surface of the connecting rod 32 slides through the outer surface of the pressing plate 21.

[0023] The effect achieved by the entire embodiment 1 is that when using the device, the mixed and crushed viscous biological bait raw materials are first fed into the interior of the storage shell 1 through the feeding port 12. When the raw materials are accumulated to a height close to the feeding port 12, the hydraulic cylinder 2 is started to push the pressure plate 21 downward to a height slightly lower than the bottom of the feeding port 12. At this time, the raw materials are compacted, and a part of the biological bait will be squeezed out through the forming holes 402 on the surface of the lower lifting plate 401. At this time, after cleaning the extruded bait, according to the eating conditions of the crab seedlings at different stages, the cylinder 3 is started to push the connecting frame 31 to move upward. At this time, the connecting rod 32 under the connecting frame 31 drives the lifting plate 401 to move upward to a preset height, and the bait inside the storage shell 1 will be compressed and pass through the forming holes. 402 is extruded, and the length of the extruded bait is consistent with the rising height of the lifting plate 401, and then the electric push rod 404 is started to push the U-shaped frame 406 to move backward. At this time, the knife holder 407 on the inner wall of the U-shaped frame 406 will cut the extruded bait into bait particles, and then repeat the above steps. This design uses the reverse extrusion method to cooperate with the knife holder 407 to cut the bait, so as to produce crab seedling bait particles with uniform length and size, and can control the particle size, so as to facilitate the feeding of crab seedlings at different stages, effectively improve the bait quality, and have good market prospects. The first mounting block 403 is mainly used for installing the electric push rod 404, and the connecting block 405 is used to connect the U-shaped frame 406 and the electric push rod 404.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the positions of the tool holder 407 and the forming hole 402 correspond, the bottom of the material storage shell 1 is hollowed out, and support legs 11 are installed near the four corners of the bottom of the material storage shell 1, and the top of the lifting plate 401 is fixedly connected to a guide frame 5, the outer surface of the guide frame 5 is in contact with the inner surface wall of the material storage shell 1, and the inner surface wall of the guide frame 5 is inclined, and the positions of the guide frame 5 and the forming hole 402 are staggered, and a limiting rod 409 is symmetrically arranged near the edge of the bottom of the lifting plate 401, and both ends of the limiting rod 409 are fixedly connected to a second mounting block 408, and the second mounting block 408 is fixedly connected to the bottom of the lifting plate 401, and the outer surface of the limiting rod 409 passes through the outer surface of the U-shaped frame 406.

[0025] The effect achieved by the entire embodiment 2 is that the support legs 11 are mainly used to support the material storage shell 1, the number of tool holders 407 corresponds to the number of rows of forming holes 402, and the middle inwardly recessed guide frame 5 plays a role in displacing the bait to the middle forming hole 402 when following the lifting plate 401. The second mounting block 408 is mainly used to install the limiting rod 409. When the U-shaped frame 406 drives the tool holder 407 to move forward and backward, the U-shaped frame 406 will slide on the surface of the limiting rod 409, making the U-shaped frame 406 more stable when moving, and when the hydraulic cylinder 2 drives the pressure plate 21 to rise and fall, the pressure plate 21 will slide on the surface of the connecting rod 32, thereby improving the stability of the pressure plate 21 when it is raised and lowered.

[0026] Working principle: When using this device, first, the biological bait raw materials that have been mixed and crushed into a viscous state are put into the interior of the storage shell 1 through the feeding port 12. When the raw materials are accumulated to a height close to the feeding port 12, the hydraulic cylinder 2 is started to push the pressing plate 21 downward to a height slightly lower than the bottom of the feeding port 12. At this time, the raw materials are compacted, and a part of the biological bait will be squeezed out through the forming holes 402 on the surface of the lifting plate 401 below. At this time, after cleaning the extruded bait, according to the eating conditions of the crab seedlings at different stages, the cylinder 3 is started to push the connecting frame 31 to move upward. At this time, the connecting rod 32 under the connecting frame 31 drives the lifting plate 401 to move upward to a preset height. After the bait inside the storage shell 1 is compressed, it will be squeezed out through the forming holes 402, and the length of the extruded bait is consistent with the rising height of the lifting plate 401. Then it is started. The electric push rod 404 pushes the U-shaped frame 406 to move backward. At this time, the knife holder 407 on the inner wall of the U-shaped frame 406 will cut the extruded bait into bait particles, and then repeat the above steps. This design cooperates with the knife holder 407 to cut the bait by reverse extrusion, so as to produce crab seedling bait particles with uniform length and size, and can control the particle size, so as to facilitate the feeding of crab seedlings at different stages, effectively improve the bait quality, and have good market prospects. In addition, when the U-shaped frame 406 drives the knife holder 407 to move forward and backward, the U-shaped frame 406 will slide on the surface of the limit rod 409, so that the U-shaped frame 406 is more stable when moving. When the hydraulic cylinder 2 drives the pressure plate 21 to rise and fall, the pressure plate 21 will slide on the surface of the connecting rod 32, thereby improving the stability of the pressure plate 21 when it is raised and lowered.
