Description

Technical Field

[0001] This utility model relates to the technical field of aquatic feed processing equipment, and in particular to a special equipment for crab feed production. Background Technology

[0002] Feed refers to the food or nutrients used to feed livestock, poultry, aquatic animals, pets, and other domesticated animals. It forms the basis of animal husbandry, aquaculture, and pet ownership. Crab feed is mainly divided into natural feed and artificial compound feed, with different feed formulas used according to the different growth stages of the crabs.

[0003] Existing specialized equipment for crab feed production requires manual screening by workers when filtering the finished feed, which easily leads to large particles and clumps clogging the screen holes. At the same time, uneven spraying occurs when spraying oil onto the feed. Furthermore, manual cleaning of the mixing tank is required after the oiling process, which greatly increases the labor intensity of workers and affects subsequent processing work, failing to meet the needs of workers.

[0004] Therefore, we propose a special equipment for crab feed production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a specialized device for crab feed production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A special equipment for crab feed production includes a mixing tank. A feeding hopper and a dryer are fixedly installed at the upper end of the mixing tank. A bearing is rotatably connected to the upper end of the mixing tank. A three-way pipe is fixedly connected to the inner ring of the bearing. A perforated stirring rod is fixedly connected to the outer ring of the bearing. A second drive motor for driving the perforated stirring rod to rotate is fixedly installed at the lower end of the mixing tank. A discharge pipe and a drain pipe are fixedly installed at the lower end of the mixing tank. A vibrating screen device is provided on the left side of the mixing tank.

[0008] The vibrating screen device includes a filter box, with a rotating shaft fixedly connected to the inner walls of the front and rear sides of the filter box. A striking rod is sleeved on the rotating shaft. A first drive motor is fixedly installed on the rear side of the filter box, and the drive end of the first drive motor is fixedly connected to the rotating shaft.

[0009] Preferably, the filter box has grooves on both the front and rear inner walls, two sliders are slidably connected in each of the two grooves, and the four sliders are fixedly connected to a fixed frame. The filter box is slidably connected in the fixed frame, and springs are fixedly connected between the two sliders on the right side and the inner wall of the corresponding groove.

[0010] Preferably, a collection box is slidably connected inside the filter box, and an anti-slip handle is fixedly connected to the right end of the collection box. A baffle is provided below the fixed frame, and the baffle is fixedly connected to the bottom wall of the filter box.

[0011] Preferably, a cleaning water tank and an oil tank are fixedly installed on the outer wall of the mixing tank. A water pump is fixedly installed in both the cleaning water tank and the oil tank. A water pipe is fixedly connected to the upper end of each of the two water pumps. The two water pipes pass through the corresponding cleaning water tank and the oil tank and are connected to the pipes corresponding to the T-junction pipe.

[0012] Preferably, the bottom wall of the filter box has multiple sieve holes, two limiting blocks are fixedly connected to the outer walls on both the left and right sides of the filter box, and two symmetrical handles are fixedly connected to the filter box.

[0013] Preferably, the upper end of the filter box is rotatably connected to a protective cover via a hinge, and the protective cover is made of transparent heat-resistant glass.

[0014] Compared with existing technologies, the advantages of this device are:

[0015] 1. During the feed collection process, this device drives the rotating shaft and the impact rod on the shaft to rotate by operating the first drive motor. The impact rod will hit the filter box, and the filter box will slide in the chute and generate vibration. At the same time, it will squeeze the spring. Then, due to the elasticity of the spring, it will return to its original position and continue to generate vibration. Under the combined action of the impact rod and the spring, the filter box will reciprocate, reducing the occurrence of screen holes being blocked by excessive feed and greatly improving production efficiency.

[0016] 2. This device can spray oil onto cooled feed, ensuring the feed surface is fully mixed with the oil, improving the feed's energy, palatability, and gloss. It can also quickly clean and dry the inside of the mixing tank, allowing for rapid oil spraying onto the next batch of feed.

[0017] In summary, this device can reduce the occurrence of screen clogging due to excessive feed during the feed collection process, and can also quickly clean and dry the mixing tank, greatly improving production efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 A special equipment for crab feed production includes a mixing tank 1, a feeding hopper 2 and a dryer fixedly installed at the upper end of the mixing tank 1, a bearing 15 rotatably connected to the upper end of the mixing tank 1, a three-way pipe 3 fixedly connected to the inner ring of the bearing 15, a perforated stirring rod 9 fixedly connected to the outer ring of the bearing 15, a second drive motor 10 for driving the perforated stirring rod 9 to rotate fixedly installed at the lower end of the mixing tank 1, a discharge pipe 4 and a drain pipe fixedly installed at the lower end of the mixing tank 1, a valve installed on the discharge pipe 4, and a vibrating screen device provided on the left side of the mixing tank 1.

[0026] The vibrating screen device includes a filter box 5. A rotating shaft 11 is fixedly connected to the inner walls of both the front and rear sides of the filter box 5. A striking rod 12 is fitted onto the rotating shaft 11. The front end of the striking rod 12 is fan-shaped. The lengths of the two sides of the front end of the striking rod 12 are slightly shorter than the distance between the rotating shaft 11 and the fixed frame 13, while the middle length of the front end of the striking rod 12 is longer than the distance between the rotating shaft 11 and the fixed frame 13. A first drive motor 6 is fixedly installed on the rear side of the filter box 5, and the drive end of the first drive motor 6 is fixedly connected to the rotating shaft 11. An inlet is provided on the filter box 5, and an outlet pipe 4 communicates with the inlet. A guide plate is fixedly connected to the inner wall of the front side of the filter box 5.

[0027] The filter box 5 has grooves on both the front and rear inner walls. Two sliders are slidably connected to each groove, and all four sliders are fixedly connected to a fixed frame 13. A filter box 14 is slidably connected inside the fixed frame 13. Springs are fixedly connected to the inner walls of the corresponding grooves for the two right-side sliders. When the operator operates the first drive motor 6 to rotate the shaft 11 and the impact rod 12 on the shaft 11, the impact rod 12 strikes the fixed frame 13 and the filter box 14. The filter box 14 slides within the grooves and vibrates, simultaneously compressing the springs. It then returns to its original position due to the spring's rebound, continuously vibrating. Under the combined action of the impact rod 12 and the springs, the filter box 14 reciprocates, blocking excessively large particles and clumps of feed within the filter box 14, reducing the occurrence of clogging the sieve holes due to excessive feed. A collection box 8 is slidably connected inside the filter box 5. An anti-slip handle is fixedly connected to the right end of the collection box 8. A baffle is located below the fixed frame 13 and is fixedly connected to the bottom wall of the filter box 5. Multiple screen holes are provided on the bottom wall of the filter box 14. Two limiting blocks are fixedly connected to the outer walls on both sides of the filter box 14. Two symmetrical handles are fixedly connected to the filter box 14. Filter boxes 14 with different screen holes can be replaced according to different production requirements. A protective cover 7 is connected to the upper end of the filter box 5 via a hinge. The protective cover 7 is made of transparent heat-resistant glass, allowing operators to observe the situation inside the filter box 5 in real time. If the screen holes of the filter box 14 become blocked or if there is too much feed in the filter box 14, causing it to malfunction, the machine can be stopped immediately and the blockage can be quickly cleared to reduce the occurrence of accidents.

[0028] A cleaning water tank and an oil tank are fixedly installed on the outer wall of the mixing tank 1. Water pumps are fixedly installed inside both the cleaning water tank and the oil tank. Water pipes are fixedly connected to the upper ends of both water pumps, passing through their respective cleaning water tanks and oil tanks, and connecting to corresponding pipes on the tee pipe 3. A corresponding valve is installed on the tee pipe 3. The oil tank contains fish oil or soybean oil, etc., and is an insulated oil storage tank with a heater fixedly installed inside.

[0029] When using this utility model, the worker puts the cooled feed into the mixing tank 1 through the feed hopper 2, then opens the valve of the three-way pipe 3 corresponding to the oil tank, starts the water pump, and simultaneously operates the second drive motor 10 to make the perforated stirring rod 9 rotate for grease spraying. After the grease spraying is completed, the worker opens the valve of the discharge pipe 4, and the feed flows into the filter box 14 through the discharge pipe 4. At the same time, the worker operates the first drive motor 6 to make the rotating shaft 11 and the impact rod 12 rotate. The impact rod 12 will repeatedly hit the fixed frame 13 and the filter box 14 to form vibration. Under the action of the impact rod 12 and the spring, the filter box 14 will reciprocate. At this time, the feed that meets the standard will fall into the collection box 8 below through the sieve holes, while oversized particles and clumps will be filtered into the filter box 14 and collected and processed by the worker. After completing the above work, close the discharge pipe 4, open the valve of the three-way pipe 3 corresponding to the cleaning water tank, clean the inside of the mixing tank 1, and then operate the dryer to dry the inside of the mixing tank 1. Then, the next batch of feed can be quickly coated with oil.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
