Description

Technical Field

[0001] This utility model relates to the technical field of fish feed feeding devices, specifically a fish feed crushing and feeding device for fishpond aquaculture. Background Technology

[0002] Fish feed comes in a variety of types, which can be categorized by nature into plant-based (such as soybean meal and corn), animal-based (such as fishmeal and earthworms), and formulated feeds (such as pelleted feed and extruded feed). By form, they include powdered, pelleted, flake, and extruded feeds, catering to the needs of different fish species and aquaculture practices. From a fish feeding perspective, finely ground feed is more suitable for fish of different body sizes and oral structures. Juvenile and small fish can easily swallow it, improving feeding efficiency. It also ensures even distribution of feed in the water, preventing large pieces from sinking and rotting, thus reducing water pollution and the risk of fish disease.

[0003] The utility model disclosed in announcement number CN206481821U is a fish feed crushing and feeding device for fishpond aquaculture. Its structure includes a feeding trough, a push plate, an L-shaped frame, a motor, a first slider, a first slide rail, a support rod, a crushing trough body, a crushing gear, a rotating shaft, a first gear, a rack, and a filter screen. The L-shaped frame has a feeding trough arranged from left to right at its bottom. A push plate is located inside the feeding trough. A rotating shaft is connected to the top of the motor, and the rotating shaft has a crushing gear and a first gear. This utility model achieves the effects of completely crushing the fish feed, timely feeding, and simple operation. When using this device, the fish feed can be crushed multiple times, reducing operation time and facilitating feeding.

[0004] Although the above-mentioned device can complete the crushing and feeding of fish bait, in actual operation, the pusher plate moves back and forth in the feeding trough. When it moves to the front, the broken fish bait falling from the crushing trough will fall behind the pusher plate. As the pusher plate moves backward, it will scrape this part of the fish bait back to the back of the feeding trough. Over time, a large amount of broken fish bait will accumulate at the back of the feeding trough, which will affect the stroke of the pusher plate and prevent it from returning to the initial position. In addition, since the end of the feeding trough is only provided with a one-way opening, the broken fish bait it releases is usually relatively concentrated and cannot be evenly distributed in the water, which is not convenient for a large number of fish to feed at the same time. Therefore, in order to solve the above problems, a fish feed crushing and feeding device for fish pond aquaculture is proposed. Utility Model Content

[0005] To address the technical problems in comparative technologies, such as the accumulation of large amounts of fish feed in the feed structure of the fish feed feeding device during use, which affects its normal operation, and the difficulty in evenly distributing the feed within a certain range, thus affecting the large-scale synchronous feeding of fish, this utility model provides a fish feed crushing and feeding device for fishpond aquaculture.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A fish feed grinding and feeding device for fishpond aquaculture includes a grinding barrel, which includes a barrel shell, a rotating grinding frame inside the barrel shell, and a discharge port at the bottom of the barrel shell with a solenoid valve; a screw feeding mechanism installed at the bottom of the grinding barrel and sealed to the discharge port; a screw pressurizing mechanism installed at the end of the screw feeding mechanism and sealed to it; and a feed extrusion hood sealed at the bottom of the screw pressurizing mechanism; wherein the feed extrusion hood includes a hood body, the bottom plate of which has a plurality of sets of extrusion holes arranged in a circumferential array, and a cutting blade is provided at the bottom of the hood body, with a gap between the cutting blade and the bottom plate of the hood body.

[0008] In one possible implementation, the spiral pressurizing mechanism includes a vertical cylindrical shell with a rotating vertical transmission rod inside. The vertical transmission rod is provided with a set of vertical spiral blades, and a reduction motor for driving the vertical transmission rod to rotate is fixedly installed at the top of the vertical cylindrical shell.

[0009] In one possible implementation, a closed cylinder is fixedly installed in the middle of the bottom plate of the main body of the cover, the bottom of the vertical transmission rod passes through the closed cylinder and is rotatably connected to it, and the cutting blade is installed at the bottom end of the vertical transmission rod.

[0010] In one possible implementation, the screw feeding mechanism includes a transverse cylindrical shell with a rotating transverse transmission rod inside. A set of transverse spiral blades are provided on the transverse transmission rod, and a geared motor for driving the transverse transmission rod to rotate is fixedly installed at the end of the transverse cylindrical shell.

[0011] In one possible implementation, a rod end support frame is provided at the end of the transverse cylindrical shell away from the second geared motor. The support frame includes a bearing seat, and the outer wall of the bearing seat is fixedly connected to the transverse cylindrical shell by a plurality of support plates arranged in a circumferential array. The end of the transverse transmission rod is rotatably connected to the bearing seat.

[0012] In one possible implementation, the shredder includes a main shaft on which a plurality of blade rings are mounted. The bottommost blade ring is fixedly provided with a plurality of auxiliary shredding blades arranged in a circumferential array, and the remaining blade rings are fixedly provided with a plurality of main shredding blades arranged in a circumferential array.

[0013] In one possible implementation, a top constraint frame is fixedly mounted on the top of the main shaft, and several hanging connecting rods are fixedly mounted on it, each connecting rod passing through and fixedly connected to all the main crushing blades.

[0014] In one possible implementation, a geared motor is fixedly installed on the top of the barrel shell to drive the main shaft to rotate, and the top of the barrel shell is respectively provided with a solid material inlet and a liquid material inlet.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] The crushing rack located in the crushing tank can crush larger fish feed and mix it with liquid medium to form a slurry-like substance. The slurry-like fish feed is then fed into the screw feeding mechanism through the discharge port. The screw feeding mechanism can transport the slurry-like fish feed to the screw pressurizing mechanism, and further agitate the fish feed during the conveying process to make it evenly mixed. The slurry-like fish feed in the screw pressurizing mechanism is subjected to downward extrusion force, which causes it to be extruded through the feed extrusion hood for feeding. The above feeding scheme does not easily cause feed accumulation during use, ensuring that the whole device can operate stably for a long time.

[0017] In addition, since the bottom plate of the main body of the feed extrusion hood is provided with evenly distributed extrusion holes, the fish feed that is extruded from the extrusion holes under pressure can be distributed more evenly and fall into the water, making it easier for fish to eat at the same time. Furthermore, the cutting blade equipped at the bottom of the main body of the hood can rotate along with the spiral pressurization mechanism when it is working, cutting the extruded fish feed into particles of similar size, making it easier for fish to eat.

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] like Figure 1 - Figure 3 As shown in the figure, the fish feed crushing and feeding device for fishpond aquaculture provided in this embodiment includes a crushing barrel 1, which includes a barrel shell 11, a rotating crushing frame 12 is provided inside the barrel shell 11, and a discharge port 13 is provided at the bottom of the barrel shell 11, on which a solenoid valve 5 is provided; a screw feeding mechanism 2, which is installed at the bottom of the crushing barrel 1 and is sealed to the discharge port 13; a screw pressurizing mechanism 3, which is installed at the end of the screw feeding mechanism 2 and is sealed to it; and a feed extrusion cover 4, which is sealed at the bottom end of the screw pressurizing mechanism 3.

[0028] In the above-mentioned structure, the crushing rack 12 located in the crushing tank 1 can crush larger fish feed and, together with the liquid medium, agitate it into a slurry-like substance. Then, it enters the screw feeding mechanism 2 through the discharge port 13. The screw feeding mechanism 2 can transport the slurry-like fish feed to the screw pressurizing mechanism 3, and further agitate the fish feed during the conveying process to make it evenly mixed. The slurry-like fish feed in the screw pressurizing mechanism 3 is subjected to downward extrusion force, which causes it to be extruded through the feed extrusion hood 4 for feeding. The above feeding scheme does not easily cause feed accumulation during use, ensuring that the whole device can operate stably for a long time.

[0029] Among them, such as Figure 4As shown, the feed extrusion cover 4 includes a cover body 41, on which a number of extrusion holes 42 arranged in a circular array are opened on the bottom plate. At the same time, a cutting blade 35 is provided at the bottom of the cover body 41, and a gap is left between the cutting blade 35 and the bottom plate of the cover body 41. The evenly distributed extrusion holes 42 allow the extruded fish feed to be distributed relatively evenly and fall into the water, making it easier for fish to feed at the same time. In addition, the cutting blade 35 can rotate with the spiral pressurizing mechanism 3 when it is working, cutting the extruded fish feed into particles of similar size, making it easier for fish to feed.

[0030] like Figure 3 - Figure 4 As shown, the spiral pressurizing mechanism 3 includes a vertical cylindrical shell 31, inside which a rotating vertical transmission rod 32 is provided. A set of vertical spiral blades 33 are provided on the vertical transmission rod 32, and a reduction motor 34 for driving the vertical transmission rod 32 to rotate is fixedly installed at the top of the vertical cylindrical shell 31. When the reduction motor 34 is working, it can drive the vertical transmission rod 32 to rotate, thereby driving the fixedly connected vertical spiral blades 33 to rotate and extrude the fish feed in the vertical cylindrical shell 31, so that it enters the feed extrusion hood 4 and is extruded. In addition, in order to drive the cutting blade 35, a closed cylinder 43 is fixedly provided in the middle of the bottom plate of the hood body 41. The bottom of the vertical transmission rod 32 passes through the closed cylinder 43 and is rotatably connected to it, and the cutting blade 35 is installed at the bottom end of the vertical transmission rod 32. Based on the above structural scheme, the vertical transmission rod 32 can drive the cutting blade 35 to rotate synchronously while rotating, cutting the extruded fish feed into small pieces, which are easy for the fish to swallow.

[0031] like Figure 3 As shown, the screw feeding mechanism 2 includes a transverse cylindrical shell 21, inside which a rotating transverse transmission rod 22 is provided. A set of transverse spiral blades 23 are provided on the transverse transmission rod 22. A second geared motor 24 for driving the transverse transmission rod 22 to rotate is fixedly installed at the end of the transverse cylindrical shell 21. When working, the second geared motor 24 can drive the transverse transmission rod 22 to rotate, thereby driving the fixedly connected transverse spiral blades 23 to rotate and extrude and convey the fish feed in the transverse cylindrical shell 21, so that it enters the screw pressurizing mechanism 3 and is extruded.

[0032] To prevent the ends of the transverse transmission rod 22 from shifting due to lack of constraint during use, therefore, as follows: Figure 3 , Figure 6As shown, a rod end support frame 25 is provided at the end of the transverse cylindrical shell 21 away from the geared motor 24. The support frame includes a bearing seat 251. The outer wall of the bearing seat 251 is fixedly connected to the transverse cylindrical shell 21 by a number of support plates 252 arranged in a circumferential array. The end of the transverse transmission rod 22 is rotatably connected to the bearing seat 251. In the above structural scheme, the bearing seat 251 can cooperate with the support plates 252 to support the end of the transverse transmission rod 22 without affecting its free rotation. The gap between the support plates 252 can allow fish feed to pass through smoothly.

[0033] like Figure 5 As shown, the grinding frame 12 includes a main shaft 121 on which several blade rings 122 are mounted. The bottommost blade ring 122 has several auxiliary grinding blades 124 arranged in a circumferential array, while the remaining blade rings 122 have several main grinding blades 123 arranged in a circumferential array. When the main shaft 121 rotates, it drives the main grinding blades 123 and auxiliary grinding blades 124 mounted on it via the blade rings 122 to rotate, thereby crushing and mixing the internal fish feed to form a paste-like substance. Simultaneously, to avoid the main grinding blades... Because the main crushing blade 123 is too long and lacks support, it may bend and deform during use. Therefore, a top constraint frame 125 is fixedly installed on the top of the main shaft 121, and several hanging connecting rods 126 are fixedly installed on it. Each connecting rod 126 passes through all the main crushing blades 123 and is fixedly connected to them. Based on the above structural scheme, the connecting rods 126 and the top constraint frame 125 can support and lift the end of the main crushing blade 123, preventing the main crushing blade 123 from bending and deforming during use.

[0034] like Figure 2 As shown, a geared motor 14 is fixedly installed on the top of the barrel shell 11 to drive the main shaft 121 to rotate. The top of the barrel shell 11 is provided with a solid material inlet 15 and a liquid material inlet 16, which can add solid and liquid fish feed raw materials into the barrel shell 11 through the above two inlets, providing the necessary structural basis for making mud-like fish feed.

[0035] The working principle and usage process of this utility model:

[0036] Solid and liquid fish feed ingredients are added into the barrel shell 11 through the solid feed inlet 15 and the liquid feed inlet 16, respectively. Then, the geared motor 14 drives the main shaft 121 to rotate. When the main shaft 121 rotates, it can drive the main crushing blade 123 and the auxiliary crushing blade 124 mounted on it through the blade ring 122 to rotate, thereby crushing and mixing the fish feed inside to make a paste-like substance.

[0037] The clay-like fish feed then falls into the transverse cylinder 21. At this time, the screw feeding mechanism 2 works, and the second geared motor 24 drives the transverse transmission rod 22 to rotate, which in turn drives the fixedly connected transverse screw blade 23 to rotate, extruding and conveying the fish feed in the transverse cylinder 21, so that it enters the screw pressurizing mechanism 3. At the same time, the screw pressurizing mechanism 3 works synchronously, and the third geared motor 34 drives the vertical transmission rod 32 to rotate, which in turn drives the fixedly connected vertical screw blade 33 to rotate, extruding and conveying the fish feed in the vertical cylinder 31, so that it enters the feed extrusion hood 4 and is extruded.

[0038] Because the bottom plate of the main body 41 of the cover has several sets of extrusion holes 42 arranged in a circular array, the extruded fish feed can be distributed more evenly and fall into the water, making it easier for the fish to eat at the same time. In addition, the equipped cutting blade 35 can rotate with the vertical transmission rod 32 when it is working, cutting the extruded fish feed into particles of similar size, making it easier for the fish to eat.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
