Description

Technical Field

[0001] This utility model relates to the field of fish feed raw material crushing technology, specifically a multi-stage crushing device for crushing fish feed raw materials. Background Technology

[0002] Fish feed ingredients refer to various natural or synthetic substances used in the production of fish feed, which are rich in nutrients required for fish growth. During the processing of fish feed ingredients, pulverizing devices are typically used to improve feed utilization and digestibility, and to minimize feed loss and contamination. A pulverizing device is a mechanical device used to crush materials. The crushed raw materials are smaller in size, with a larger surface area, which helps fish better digest and absorb the nutrients. At the same time, the uniform particle size of the crushed raw materials facilitates even mixing with other ingredients, ensuring a uniform distribution of nutrients in each serving of feed and preventing any particular component from being excessive or insufficient.

[0003] In the prior art, when fish feed raw materials are crushed by a crushing device, the crushing is usually achieved by the rotation of crushing blades or crushing rollers. Since this crushing method is relatively simple, it is not convenient to crush fish feed raw materials in multiple stages. As a result, the fish feed raw materials may not be crushed completely during the crushing process, which is not conducive to improving the crushing quality and effect. Therefore, in order to solve the above problems, a multi-stage crushing device for crushing fish feed raw materials is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-stage crushing device for crushing fish feed raw materials, so as to solve the problem mentioned in the background art that the crushing method is relatively simple and not convenient for multi-stage crushing of fish feed raw materials, which may result in incomplete crushing of fish feed raw materials during the crushing process, thus which is not conducive to improving the quality and effect of crushing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage crushing device for crushing fish feed raw materials, comprising a box body, the box body including a crushing box, a hopper provided at the top of the crushing box, a crushing roller movably connected to the inner side of the crushing box, a first motor fixedly installed on the surface of the crushing box, the crushing roller and the output end of the first motor fixedly connected, a gear fixedly connected to the surface of the crushing roller, and a discharge port opened on the inner side of the crushing box;

[0006] The crushing box is equipped with a crushing mechanism at its top. The crushing mechanism includes a crushing tank, which is fixedly connected to the top of the crushing box. The hopper is fixedly connected to the top of the crushing tank. A support block is fixedly connected to the top of the crushing tank. A first rotating rod is movably connected to the inner side of the support block. A first conical tooth is fixedly connected to the surface of the first rotating rod. A second motor is fixedly installed on the surface of the support block. A second rotating rod is movably connected to the inner side of the crushing tank. A second conical tooth is fixedly connected to the top of the second rotating rod. A first crushing rod is fixedly connected to the surface of the second rotating rod.

[0007] Preferably, the crushing mechanism further includes a third rotating rod, which is movably connected to the inside of the crushing tank. A third conical tooth is fixedly connected to the top end of the third rotating rod, and a first connecting plate is fixedly connected to the surface of the third rotating rod. A second crushing rod is fixedly connected to the surface of the first connecting plate.

[0008] Preferably, the end of the first rotating rod away from the first conical tooth is fixedly connected to the output end of the second motor, and the second rotating rod is movable inside the third rotating rod and the third conical tooth.

[0009] Preferably, a screening mechanism is provided inside the crushing box. The screening mechanism includes a fixed block, which is fixedly connected to the inner wall of the crushing box. A spring is fixedly connected to the upper surface of the fixed block, and a sieve plate is fixedly connected to the top of the spring. A second connecting plate is fixedly connected to the inner wall of the crushing box. A reciprocating screw is movably connected to the inner side of the second connecting plate. A third motor is fixedly installed at the bottom of the second connecting plate. A sleeve is movably connected to the surface of the reciprocating screw. A connecting block is fixedly connected to the top of the sleeve, and a limit rod is fixedly connected to the bottom of the connecting block.

[0010] Preferably, the sieve plate is movably connected to the inside of the crushing box, and the reciprocating screw is fixedly connected to the output end of the third motor.

[0011] Preferably, the limiting rod is in two sets and fixedly connected to the connecting block, and the limiting rod is movable inside the second connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The first rotating rod is driven by the second motor to rotate, which in turn drives the first conical tooth to rotate and transmit power to the second and third conical teeth. This allows the first and second crushing rods to rotate in opposite directions within the crushing tank. As a result, the fish feed raw materials are initially crushed before being crushed by the crushing roller, making the fish feed raw materials finer. This facilitates better crushing of the fish feed raw materials by the crushing roller, reducing the crushing load on the crushing roller. At the same time, the opposite rotation of the first and second crushing rods allows for better contact with the fish feed raw materials, thereby improving the quality and efficiency of crushing and making the crushing more thorough.

[0014] 2. The sieve plate allows for the screening of fish feed ingredients, enabling unsuitable ingredients to be further crushed, thus ensuring crushing quality. Simultaneously, the reciprocating screw rotation drives the connecting block to move vertically, which, in conjunction with the spring, causes the connecting block to strike the sieve plate. The resulting vibration accelerates the separation of fish feed ingredients and prevents their accumulation on the sieve plate, avoiding blockage and ensuring effective screening.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] The first motor 13, the second motor 24, and the third motor 35 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, and therefore will not be described in detail here.

[0023] A multi-stage crushing device for crushing fish feed raw materials includes a housing, which includes a crushing chamber 1. A hopper 11 is provided at the top of the crushing chamber 1. A crushing roller 12 is movably connected to the inner side of the crushing chamber 1. A first motor 13 is fixedly installed on the surface of the crushing chamber 1. The output end of the crushing roller 12 and the first motor 13 are fixedly connected. A gear 14 is fixedly connected to the surface of the crushing roller 12. A discharge port 15 is provided on the inner side of the crushing chamber 1. The fish feed raw materials can enter the crushing chamber 1 through the setting of the hopper 11. The first motor 13 drives the crushing roller 12 to rotate. With the setting of two sets of gears 14, the two sets of crushing rollers 12 can rotate simultaneously in opposite directions, thereby realizing the crushing of fish feed raw materials.

[0024] A crushing mechanism is provided at the top of the crushing box 1. The crushing mechanism includes a crushing tank 2, which is fixedly connected to the top of the crushing box 1. A hopper 11 is fixedly connected to the top of the crushing tank 2. A support block 21 is fixedly connected to the top of the crushing tank 2. A first rotating rod 22 is movably connected to the inner side of the support block 21. A first conical tooth 23 is fixedly connected to the surface of the first rotating rod 22. A second motor 24 is fixedly installed on the surface of the support block 21. A second rotating rod 25 is movably connected to the inner side of the crushing tank 2. A second conical tooth 26 is fixedly connected to the top of the second rotating rod 25. A first crushing rod 27 is fixedly connected to the surface of the second rotating rod 25. The first crushing rod 27 is rotated by the second rotating rod 25, so that the fish feed raw materials can be crushed to a certain extent before being crushed by the crushing roller 12. This can better ensure the crushing effect of the crushing roller 12 on the fish feed raw materials and help reduce the crushing burden of the crushing roller 12.

[0025] Furthermore, the crushing mechanism also includes a third rotating rod 28, which is movably connected to the inside of the crushing tank 2. A third conical tooth 29 is fixedly connected to the top of the third rotating rod 28, and a first connecting plate 210 is fixedly connected to the surface of the third rotating rod 28. A second crushing rod 211 is fixedly connected to the surface of the first connecting plate 210. By rotating the third rotating rod 28, the first connecting plate 210 can be rotated, which in turn causes the second crushing rod 211 to rotate. The rotation of the second crushing rod 211 can crush the fish feed raw materials in the opposite direction, thus making the crushing more thorough.

[0026] Furthermore, the end of the first rotating rod 22 away from the first conical tooth 23 is fixedly connected to the output end of the second motor 24, and the second rotating rod 25 is movable inside the third rotating rod 28 and the third conical tooth 29. Through the setting of the first conical tooth 23, the transmission of the second conical tooth 26 and the third conical tooth 29 can be realized, which makes it easier for the second rotating rod 25 and the third rotating rod 28 to drive the first crushing rod 27 and the second crushing rod 211 to rotate in opposite directions, thereby improving the crushing effect of fish feed raw materials.

[0027] Furthermore, a screening mechanism is provided inside the crushing box 1. The screening mechanism includes a fixed block 3, which is fixedly connected to the inner wall of the crushing box 1. A spring 31 is fixedly connected to the upper surface of the fixed block 3, and a screen plate 32 is fixedly connected to the top of the spring 31. A second connecting plate 33 is fixedly connected to the inner wall of the crushing box 1. A reciprocating screw 34 is movably connected to the inner side of the second connecting plate 33. A third motor 35 is fixedly installed at the bottom of the second connecting plate 33. A sleeve 36 is movably connected to the surface of the reciprocating screw 34. A connecting block 37 is fixedly connected to the top of the sleeve 36, and a limit rod 38 is fixedly connected to the bottom of the connecting block 37. By setting the screen plate 32, the raw materials can be screened. By setting the connecting block 37 in conjunction with the elastic properties of the spring 31, the screen plate 32 can vibrate, thereby accelerating the separation of raw materials by the screen plate 32 and preventing the raw materials from accumulating or clogging on the screen plate 32.

[0028] Furthermore, the screen plate 32 is movably connected to the inside of the crushing box 1, and the reciprocating screw 34 and the output end of the third motor 35 are fixedly connected. By rotating the reciprocating screw 34, the sleeve 36 can drive the connecting block 37 to move vertically, and then the connecting block 37 rises and strikes the screen plate 32, which can prevent the screen plate 32 from clogging and facilitate the screen plate 32 to better screen the raw materials.

[0029] Furthermore, the limiting rods 38 are fixedly connected to the connecting block 37 in two sets. The limiting rods 38 move inside the second connecting plate 33. By setting the limiting rods 38, the connecting block 37 can be limited, which can prevent the connecting block 37 from shifting under the action of the reciprocating screw 34, and facilitate the stable vertical movement of the connecting block 37.

[0030] Working principle: During use, the second motor 24 is electrically connected to an external power source. The operator starts the second motor 24 by pressing the switch. The second motor 24 drives the first rotating rod 22 to rotate. The first conical tooth 23 rotates under the action of the first rotating rod 22, and transmits power to the second conical tooth 26 and the third conical tooth 29. This enables the second rotating rod 25 to drive the first crushing rod 27 to rotate under the action of the second conical tooth 26. The third rotating rod 28 drives the first connecting plate 210 and the second crushing rod 211 to rotate under the action of the third conical tooth 29. This enables the first crushing rod 27 and the second crushing rod 211 to perform preliminary crushing of fish feed raw materials. Moreover, the first crushing rod 27 and the second crushing rod 211 rotate in opposite directions, resulting in better crushing effect.

[0031] The third motor 35 is electrically connected to an external power source. The operator starts the third motor 35 by pressing a switch. The operation of the third motor 35 drives the reciprocating screw 34 to rotate. The connecting block 37 is limited by the limiting rod 38, so that the sleeve 36 will move vertically under the action of the reciprocating screw 34. At the same time, the limiting rod 38 moves within the second connecting plate 33. With the elasticity of the spring 31, the vertical movement of the connecting block 37 can knock on the screen plate 32 and cancel the knocking. It can also realize the reset of the screen plate 32 under the action of the spring 31. In this way, the vibration generated by the knocking can accelerate the separation and prevent the screen plate 32 from clogging.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
