Description

Technical Field

[0001] This utility model relates to the field of feed preparation technology, specifically a stirring device for tilapia feed preparation. Background Technology

[0002] In modern aquaculture, fish feed refers to organic or inorganic compounds that provide animals with nutrients such as energy, protein, fat, vitamins, and minerals, or a mixture of various nutrients or some nutrients with various non-nutritive organic and inorganic compounds. Since fish feed is processed by stirring, stirring devices are required.

[0003] Currently, in the preparation of tilapia feed, various raw materials are usually crushed first to achieve better mixing results. This is because crushed raw materials have smaller particles and a larger specific surface area, which theoretically is more conducive to subsequent mixing operations. However, in actual production, it has been found that even after crushing, the raw materials still frequently clump together when entering the mixing tank. The formation of these clumps is mainly due to the combined effects of various factors such as the viscosity and moisture differences of the raw materials themselves, as well as the compression they experience during storage and transportation. The presence of clumps seriously hinders the uniform mixing of the feed. Clumped raw materials cannot be evenly dispersed during mixing like normal particles, resulting in uneven distribution of the various components in the feed. This reduces the subsequent mixing effect of the feed. Therefore, a mixing device for tilapia feed preparation is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a stirring device for tilapia feed preparation, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a mixing device for tilapia feed preparation, comprising a housing, an inlet at the top of the housing, a crushing component and a mixing mechanism inside the housing, and an outlet at the bottom of the housing. The mixing mechanism includes:

[0006] A stirring shaft is driven by a driving component, and a stirring rod is fixedly connected to the outer wall of the stirring shaft.

[0007] An auxiliary stirring component is disposed inside the housing.

[0008] Preferably, the auxiliary stirring assembly includes a movable block, a connecting rod is fixedly connected to the outer wall of the movable block, and a guide block is fixedly connected to the end of the connecting rod away from the movable block.

[0009] Preferably, a hinge rod is hinged to the outer wall of the movable block, and a swing plate is hinged to the end of the hinge rod away from the movable block.

[0010] Preferably, a reciprocating screw groove is provided on the outer wall of the stirring shaft. The reciprocating screw groove matches the moving block. The stirring shaft is driven to rotate by the driving component. The guide block slides on the guide bar, and then the moving block slides up and down on the reciprocating screw groove, which drives the hinge rod to move. This in turn drives the swing plate to swing, so that the crushed raw material can pass through the swing plate at different angles after being transported. The crushed raw material is at different heights when it slides over the swing plate, and then impacts the inner wall of the box for dispersion, which facilitates the full mixing of the subsequent raw materials.

[0011] Preferably, the crushing component includes a rotating shaft, which is driven by a driving component. A crushing roller is fixedly connected to the outer wall of the rotating shaft, and crushing teeth are fixedly connected to the inner wall of the housing. The rotating shaft is driven to rotate by the driving component, which in turn drives the crushing roller to rotate. The crushing roller works in conjunction with the crushing teeth to fully crush the raw material. At the same time, during the rotation of the crushing roller, the crushed raw material can be thrown towards the stirring mechanism area under the action of centrifugal force, so that the raw material is dispersed as much as possible.

[0012] Preferably, the feed inlet is located above the rotating shaft.

[0013] Preferably, the inner wall of the box is provided with an inclined eave, and a guide strip is fixedly connected to the inner wall of the box. The guide strip is slidably connected to the guide block. The use of the inclined eave facilitates the sliding of raw materials.

[0014] This invention provides a mixing device for preparing tilapia feed. It has the following beneficial effects:

[0015] (1) The mixing device for preparing tilapia feed crushes the raw materials through the crushing component. Under the action of centrifugal force, the raw materials are thrown into the mixing mechanism area. When the mixing shaft rotates, the moving block slides up and down on the reciprocating screw groove, which drives the swing plate to swing. This causes the crushed raw materials to be at different heights when they slide over the swing plate and impact the inner wall of the box to disperse them, increasing the degree of dispersion of the raw materials and making the raw materials as dispersed as possible, which is convenient for subsequent full mixing.

[0016] (2) The mixing device for tilapia feed preparation drives the crushing roller to rotate through the rotating shaft of the crushing component, and works with the crushing teeth to fully crush the raw materials. The feed inlet is located above the rotating shaft, which makes it convenient for the raw materials to directly enter the crushing area. The inner wall of the box is equipped with an inclined eaves to facilitate the sliding of the raw materials. The overall process from feeding, crushing to mixing is optimized, and the feed preparation efficiency is improved. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model proposes a mixing device for tilapia feed preparation, including a box body 1, a feed inlet 2 at the top of the box body 1, a crushing component 3 and a mixing mechanism 4 inside the box body 1, and a discharge outlet 5 at the bottom of the box body 1.

[0028] In an embodiment of this utility model, in order to crush feed ingredients, the crushing component 3 specifically includes a rotating shaft 31, which is driven by a driving component. A crushing roller 32 is fixedly connected to the outer wall of the rotating shaft 31, and crushing teeth 33 are fixedly connected to the inner wall of the housing 1. The feed inlet 2 is located above the rotating shaft 31. After the raw material is added through the feed inlet 2, the raw material falls above the crushing roller 32. Then, the driving component drives the rotating shaft 31 to rotate clockwise, which in turn drives the crushing roller 32 to rotate clockwise. Under the cooperation of the crushing teeth 33, the feed ingredients are crushed.

[0029] Furthermore, the stirring mechanism 4 includes a stirring shaft 41 and an auxiliary stirring assembly 43. The stirring shaft 41 is driven by a driving component. A stirring rod 42 is fixedly connected to the outer wall of the stirring shaft 41. The auxiliary stirring assembly 43 is disposed inside the housing 1 and includes a moving block 431. A reciprocating screw groove 411 is formed on the outer wall of the stirring shaft 41, which matches the moving block 431. A connecting rod 432 is fixedly connected to the outer wall of the moving block 431. A guide block 433 is fixedly connected to the end of the connecting rod 432 away from the moving block 431. A hinge rod 434 is hinged to the outer wall of the moving block 431. A guide block 433 is hinged to the end of the hinge rod 434 away from the moving block 431. The swing plate 435 has an inclined eave 101 on the inner wall of the box 1. The inclined eave 101 facilitates the sliding of raw materials. A guide strip 102 is fixedly connected to the inner wall of the box 1. The guide strip 102 is slidably connected to the guide block 433. When the driving component drives the stirring shaft 41 to rotate, the moving block 431 slides up and down on the reciprocating screw groove 411, causing the swing plate 435 to swing. After the raw materials are crushed by the crushing component 3, the raw materials are thrown towards the stirring mechanism 4 area under the action of centrifugal force. This causes the crushed raw materials to be at different heights when sliding over the swing plate 435 and to impact the inner wall of the box 1 to disperse them, increasing the degree of dispersion of the raw materials and making them as dispersed as possible, which is conducive to thorough mixing in the later stage.

[0030] The driving component is an existing driving structure, such as a motor, stepper motor, or other driving device.

[0031] It should be noted that all the electrical components mentioned above are existing technology products. Those skilled in the art should select, install, and debug the circuits according to their needs to ensure that all electrical appliances function properly. All components are general standard parts or parts known to those skilled in the art, and their structures and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are imposed here.

[0032] In use, feed ingredients are first added into the housing 1 through the feed inlet 2. The ingredients fall above the crushing roller 32, and then the drive unit drives the rotating shaft 31 to rotate clockwise, which in turn drives the crushing roller 32 to rotate clockwise. Under the action of the crushing teeth 33, the feed ingredients are crushed. At the same time, the drive unit is started to drive the stirring shaft 41 to rotate. The moving block 431 slides up and down on the reciprocating screw groove 411, which drives the swing plate 435 to swing. After the crushing component 3 crushes the ingredients, the ingredients are thrown towards the stirring mechanism 4 area under the action of centrifugal force. This makes the crushed ingredients at different heights when they slide over the swing plate 435 and impact the inner wall of the housing 1 to disperse them, so that the ingredients are dispersed as much as possible and the feed ingredients are fully mixed.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
