Description

Technical Field

[0001] This utility model relates to the field of fish feed pretreatment technology, and in particular to a multifunctional fish feed pretreatment device. Background Technology

[0002] Fisheries refers to the industry of unified breeding and harvesting of aquatic animals such as fish and shrimp. During the breeding stage, fish feed needs to be continuously fed into the river for the shrimp to eat. Fish feed is obtained by crushing, mixing, and puffing various raw materials with different nutritional values. The quality of fish feed can directly affect feed digestibility, water pollution and breeding efficiency. Therefore, it is necessary to carefully carry out the pretreatment of fish feed.

[0003] In the pre-treatment stage of fish feed, larger raw materials need to be crushed. Sometimes, to ensure particle fineness, multiple crushing processes are required. Then, these fined raw materials are mixed and stirred with other raw materials in a container. After being ejected from the machine, final processing steps such as puffing are performed. Each step in the pre-treatment stage is independent of each other and is operated separately, which is time-consuming and results in low overall pre-treatment efficiency. Moreover, after using various mechanical equipment, in order to avoid bacterial growth caused by residual raw materials, the machinery in each step needs to be cleaned separately. The numerous steps greatly increase the labor intensity of workers.

[0004] Therefore, in the existing fish feed pretreatment stage, each operation step is carried out independently, which results in long pretreatment time, low efficiency, and the need for separate subsequent cleaning stages, which is cumbersome and increases the labor burden on workers. Therefore, a multi-functional fish feed pretreatment device can be designed. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-8 This utility model provides an embodiment of a multifunctional pretreatment device for fish feed, including a shell 1; it also includes a discharge cylinder 2 fixedly connected to the bottom of the shell 1, a feed hopper 3 fixedly connected to the top of the shell 1, a crushing mechanism located inside the shell 1 and directly below the feed hopper 3, an inclined screen 9 located inside the shell 1 and below the crushing mechanism, a stirring mechanism located at the lower end of the inner side of the shell 1, a discharge mechanism located inside the discharge cylinder 2, a notch 10 opened at the right end of the shell 1, a transparent glass plate 11 fixed to the upper end of the notch 10, a support frame 12 fixedly connected to the bottom wall of the notch 10, a collection box 13 movably located at the upper end of the support frame 12, a sealing mechanism located on the right side of the outer side of the shell 1, and a cleaning mechanism located at the top of the inner side of the shell 1. The crushing mechanism is used to crush the input raw materials, and the stirring mechanism is used to crush the raw materials. The mixing and stirring process is carried out. The discharge mechanism is used to extrude the mixed raw materials. The sealing mechanism is used to seal the gap 10. The cleaning mechanism is used to clean the equipment, including the casing 1 and the discharge cylinder 2. During the pretreatment process, the raw materials are poured into the casing 1 from the feed hopper 3. The raw materials are first crushed by the crushing mechanism. The crushed raw materials fall onto the screen 9 for filtration and separation. The larger crushed raw materials that do not meet the usage requirements are collected in the collection box 13 and then taken out by the worker for secondary crushing. The smaller crushed raw materials that meet the usage requirements fall to the bottom of the casing 1 and are mixed and stirred by the stirring mechanism. Finally, the discharge mechanism discharges the raw materials. During the cleaning stage, the collection box 13 is first removed, and the gap 10 is completely sealed by the sealing mechanism. The cleaning mechanism is connected to the water pump pipeline and then the internal equipment is rinsed.

[0027] Please see Figures 2-5 In this embodiment, the crushing mechanism includes two crushing rollers 401 rotatably connected inside the housing 1 via a rotating shaft, gears 402 fixedly connected to the rotating shafts of the two crushing rollers 401, and a crushing drive motor 403 fixedly connected to the front side of the housing 1. The output shaft of the crushing drive motor 403 is fixedly connected to the rotating shaft of one of the crushing rollers 401. The crushing drive motor 403 drives the crushing roller 401 to rotate. The two gears 402 are meshed together. When the crushing drive motor 403 is started, it drives the corresponding crushing roller 401 to rotate. Then, through the meshing of the two gears 402, it drives the other crushing roller 401 to rotate. Thus, the two crushing rollers 401 rotating in opposite directions pulverize the raw materials that fall in. The stirring mechanism includes a stirring shaft 501 rotatably connected inside the housing 1, multiple sets of stirring rods 502 fixedly connected to the outside of the stirring shaft 501, and a fixed connecting... A stirring drive motor 503 is connected to the left side of the outer wall of the casing 1. The output shaft of the stirring drive motor 503 is fixedly connected to the stirring shaft 501. The stirring drive motor 503 is used to drive the stirring shaft 501 to rotate. When the stirring drive motor 503 is started, it drives the stirring shaft 501 to rotate. The stirring shaft 501 drives each stirring rod 502 to rotate, thus fully mixing the materials. The discharge mechanism includes a rotating rod 601 rotatably connected inside the discharge cylinder 2, a spiral blade 602 fixedly connected to the surface of the rotating rod 601, and a discharge drive motor 603 fixedly connected to the left side of the outside of the discharge cylinder 2. The output shaft of the discharge drive motor 603 is fixedly connected to the rotating rod 601. The discharge drive motor 603 is used to drive the rotating rod 601 to rotate. When the discharge drive motor 603 is started, it drives the rotating rod 601 to rotate. The rotating rod 601 drives the spiral blade 602 to rotate, thereby pushing the mixed materials outward to complete the discharge work.

[0028] Please see Figures 6-8In this embodiment, the screen 9 is set with the left side higher than the right side. A connecting plate 14 is fixedly connected to the left end of the screen 9, and a vibration motor 15 is fixedly connected to the bottom of the connecting plate 14. The vibration motor 15 is used to vibrate the screen 9 to filter the crushed material. Starting the vibration motor 15 drives the screen 9 to vibrate, which facilitates the rapid screening of the falling raw materials. The sealing mechanism includes a fixed plate 701 fixedly connected to the right side of the outer side of the casing 1, a sealing drive cylinder 702 fixed to the upper end of the fixed plate 701, and a sealing plate 703 fixed to the output end of the sealing drive cylinder 702. The sealing drive cylinder 702 is used to control the sealing plate 703 to lift and lower. Starting the sealing drive cylinder 702 drives the sealing plate 703 to rise. On the one hand, it can support and fix the collection box 13, and on the other hand, it can seal the gap 10. The cleaning mechanism includes a diversion pipe 801 fixed inside the top side of the housing 1, multiple water spray pipes 802 fixed outside the diversion pipe 801, and a water supply pipe 803 fixed at the top of the diversion pipe 801. The water spray pipes 802 are provided with three different orientations. The upper part of the water supply pipe 803 penetrates the top wall of the housing 1. The water supply pipe 803 is used to connect to an external water pump pipeline. The external water pump pumps high-pressure water into the water supply pipe 803. The water flows into the diversion pipe 801 for diversion, and then sprays out in multiple directions from each water spray pipe 802. From top to bottom, it performs a one-time cleaning of each device inside the housing 1.

[0029] During pretreatment, the raw material is poured into the machine casing 1 from the feed hopper 3. It first passes through the crushing mechanism for crushing. The crushing drive motor 403 is started, driving the corresponding crushing roller 401 to rotate. Then, through the meshing of two gears 402, another crushing roller 401 is driven to rotate. Thus, the two counter-rotating crushing rollers 401 crush the incoming raw material. The crushed material falls onto the screen 9. The vibration motor 15 is started, causing the screen 9 to vibrate, facilitating rapid screening of the incoming raw material. Larger materials that do not meet the usage requirements are then removed. The crushed raw materials are collected in the collection box 13, and then taken out by the workers for secondary crushing. The finer crushed raw materials that meet the usage requirements fall into the bottom of the machine casing 1 and are mixed by the stirring mechanism. The stirring drive motor 503 is started to drive the stirring shaft 501 to rotate, and the stirring shaft 501 drives each stirring rod 502 to rotate, so as to fully mix the materials. Finally, the material is discharged by the discharge mechanism. The discharge drive motor 603 is started to drive the rotating rod 601 to rotate, and the rotating rod 601 drives the spiral blade 602 to rotate, thereby pushing the mixed material outward to complete the discharge work.

[0030] During the cleaning phase, the collection box 13 is first removed, and the gap 10 is completely sealed using the sealing mechanism. The sealing drive cylinder 702 is activated to drive the sealing plate 703 to rise, sealing the gap 10 of the housing 1. The cleaning mechanism is connected to an external water pump pipeline, and the water delivery pipe 803 is used to connect to the external water pump pipeline. The external water pump pumps high-pressure water into the water delivery pipe 803. The water flows into the diversion pipe 801 for diversion, and then sprays out in multiple directions from each spray pipe 802, performing a one-time cleaning of the equipment inside the housing 1 from top to bottom.

[0031] By implementing the above steps, including setting up crushing, mixing, discharging, and sealing mechanisms, multiple processes for fish feed pretreatment are integrated into a single piece of equipment. This also allows for screening and secondary crushing of the raw materials, ensuring continuous operation and improving efficiency. Furthermore, a cleaning mechanism is added to perform a continuous cleaning of the entire system, reducing steps and lowering the workload for workers. This addresses the problems of existing fish feed pretreatment processes where each step is performed independently, resulting in long pretreatment times, low efficiency, and the need for separate cleaning stages, which are cumbersome and increase the workload for workers.
