Description

Technical Field

[0001] This invention patent relates to the field of mechanical technology, specifically to a crusher for producing shrimp larvae feed. Background Technology

[0002] Currently, small-scale farmers or feed processing workshops generally use vertical crushers to grind shrimp larvae feed ingredients. Such equipment usually includes a vertically set crushing chamber and a crusher installed at the bottom of the crushing chamber. The crusher drives the cutter head or hammer to rotate at high speed at the bottom of the chamber, applying impact and shearing forces to the material fed into the chamber in order to crush it to the target fineness.

[0003] However, due to limitations in the installation position of the crusher and the movement characteristics of the material within the chamber, existing vertical crushing equipment has a significant blind spot during operation. The material fed into the crushing chamber naturally settles to the bottom of the chamber under gravity. The crusher mainly focuses on crushing the material in the lower part of the chamber, which is close to the cutter head. However, the material located in the upper part of the chamber, far from the cutter head, is difficult to participate in the high-intensity crushing cycle at the bottom, while the material above remains in a relatively coarse particle state. Therefore, we need to provide a crusher for producing shrimp larvae feed. Summary of the Invention

[0004] The purpose of this invention is to provide a crusher for producing shrimp larvae feed. By assembling a crusher at the bottom of the mixing tank and setting a swing component on the outer periphery of the mixing tank, the mixing tank can rotate 360 ​​degrees relative to the side plate and generate a swing motion synchronously during the crushing process. During the swinging process, the material in the mixing tank is continuously thrown, rolled, and redistributed, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this invention provides the following technical solution: a crusher for producing shrimp larvae feed, comprising: a mixing tank with an opening at the top, and a cover at the opening at the top of the mixing tank.

[0006] The crushing mechanism is installed at the center of the bottom of the mixing tank. The crushing mechanism is used to crush the shrimp fry feed put into the mixing tank and can shake the mixing tank.

[0007] The crushing mechanism includes a crusher and a swing assembly. The crusher is installed at the bottom of the mixing tank and is used to crush the shrimp larvae feed inside the mixing tank. The swing assembly is installed on the outer periphery of the mixing tank to rotate the mixing tank and the shrimp larvae feed inside.

[0008] Preferably, the crusher includes a base fixed to the bottom of the mixing tank, a driver is provided in the base, a crushing paddle is installed at the output end of the driver, and the carbide blade head on the surface of the crushing paddle is located inside the mixing tank.

[0009] Preferably, the oscillating assembly includes two side plates, the tops of which are respectively hinged to the two sides of the mixing tank. The mixing tank can rotate 360 ​​degrees relative to the side plates, and the bottoms of both side plates are fixedly installed on the top of the base. An adsorption component is installed inside the base.

[0010] Preferably, the adsorption element includes a sleeve embedded in the base, a piston is slidably installed on the inner wall of the sleeve, an adjusting rod is threadedly installed on the top of the sleeve, and the top of the piston is rotatably connected to the lower end of the adjusting rod.

An adsorption plate is fixedly installed on the bottom of the sleeve, and the bottom surface of the adsorption plate is lower than the bottom surface of the base.

[0012] Preferably, it also includes a quick-release component, which is installed inside the cover to enable quick locking and separation of the cover from the mixing tank.

[0013] The quick-release assembly includes insert plates that are slidably installed on both sides of the cover. Slots that engage with the insert plates are provided on both sides of the mixing tank. A transmission rod is hinged to an adjacent side of each of the two insert plates. A drive unit that synchronously pulls the two transmission rods is provided on the top of the cover.

[0014] Preferably, the drive unit includes a movable block slidably mounted on the top of the cover, with one end of each of the two transmission rods hinged to both sides of the movable block, and pull rings fixedly mounted on both sides of the movable block.

[0015] Preferably, a threaded rod is fixedly installed on the top of the movable block, a nut is threaded onto the surface of the threaded rod, and a handle is slidably installed on the surface of the threaded rod, with the handle fixed to the top of the cover.

[0023] The technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] Please see Figure 1-5 This invention patent provides a technical solution: a crusher for producing shrimp fry feed, including a mixing tank 1 with an opening at the top and a cover 2 at the opening at the top of the mixing tank 1; and a crushing mechanism 3, which is assembled at the bottom of the mixing tank 1 and can shake the mixing tank 1 when crushing the shrimp fry feed put into the mixing tank 1.

[0025] The crushing mechanism 3 includes a crusher 31 and a swing assembly 32. The crusher 31 is installed at the bottom of the mixing tank 1 and is used to crush the shrimp fry feed inside the mixing tank 1. The swing assembly 32 is installed on the outer periphery of the mixing tank 1 to realize the rotation of the mixing tank 1 and the shrimp fry feed inside. It can rotate 360° clockwise or counterclockwise, so that the material continuously changes its relative position with the cutter head in the circumferential direction, ensuring that the material in all parts of the tank can get sufficient crushing opportunities. Its swing and rotation combined motion causes continuous relative displacement and shearing action between the tank wall and the material.

[0026] like Figure 4As shown, the crusher 31 includes a base 311 fixedly installed at the bottom of the mixing tank 1. The base 311 is provided with a driver 312. The output end of the driver 312 is equipped with a crushing paddle 313 (made of high-strength alloy). The crushing paddle 313 has blades distributed along its surface. The blades extend into the interior of the mixing tank 1. The driver 312 is supported at the bottom of the mixing tank 1 by the base 311 and drives the crushing paddle 313 to rotate around its axis to apply impact and shearing forces to the material in the mixing tank 1.

[0027] like Figure 2 As shown, the oscillating assembly 32 includes two opposing side plates 321. The tops of the two side plates 321 are respectively hinged to the two sides of the mixing tank 1. The mixing tank 1 can rotate 360° relative to the side plates 321 around the vertical axis. A base 311 is fixedly installed at the bottom of the two side plates 321. An adsorption member 323 is installed in the base 311. The adsorption member 323 is used to adsorb and fix the base 311 to the workbench. The mixing tank 1 is suspended and supported between the two side plates 321 through the hinge points on both sides, and oscillates back and forth around the hinge points under the action of external force.

[0028] like Figure 2 As shown, the adsorption component 323 includes a sleeve 3231 embedded in the base 311. A piston 3232 (with an outer rubber outer layer, similar to the principle of a syringe) is slidably mounted on the inner wall of the sleeve 3231. The outer peripheral wall of the piston 3232 is slidably sealed to the inner wall of the sleeve 3231. An adjusting rod 3233 is threadedly mounted on the top of the sleeve 3231. The lower end of the adjusting rod 3233 extends into the sleeve 3231 and is rotatably connected to the top of the piston 3232. When the adjusting rod 3233 rotates relative to the sleeve 3231, it moves axially and pushes the piston 3232 to slide along the inner wall of the sleeve 3231, thereby changing the volume of the inner cavity of the sleeve 3231.

[0029] like Figure 3 As shown, a handwheel 4 is fixedly installed on the top of the adjusting rod 3233. The outer peripheral wall of the piston 3232 is tightly fitted with the inner wall of the sleeve 3231. An adsorption plate 5 (deformable silicone material) is fixedly installed on the bottom of the sleeve 3231. The bottom surface of the adsorption plate 5 is lower than the bottom surface of the base 311. When the handwheel 4 drives the adjusting rod 3233 to rotate, the adjusting rod 3233 pushes the piston 3232 to slide along the inner wall of the sleeve 3231, so that the inner cavity of the sleeve 3231 generates negative or positive pressure. Under the action of negative pressure, the adsorption plate 5 is adsorbed onto the workbench surface.

[0030] The crusher in this embodiment also includes a quick-release component 6, which is installed inside the cover 2 and is used to quickly lock and separate the cover 2 from the mixing tank 1.

[0031] The quick-release assembly 6 includes insert plates 61 that are slidably installed on both sides of the cover 2. The mixing tank 1 has slots 62 on both sides that engage with the insert plates 61. The two insert plates 61 are hinged to adjacent sides with transmission rods 63. The top of the cover 2 is provided with a drive part 64 that synchronously pulls the two transmission rods 63.

[0032] like Figure 5 As shown, the drive unit 64 includes a movable block 641 slidably mounted on the top of the cover 2. The adjacent ends of the two transmission rods 63 are respectively hinged to the two sides of the movable block 641. Pull rings 642 are fixedly installed on both sides of the movable block 641. When the movable block 641 slides along the top of the cover 2 under the action of external force, the two transmission rods 63 simultaneously pull the two insert plates 61 to slide in opposite directions, so that the two insert plates 61 are synchronously inserted into or withdrawn from the corresponding slots 62.

[0033] like Figure 5 As shown, a threaded rod 7 is fixedly installed on the top of the movable block 641, a nut 8 is threadedly installed on the surface of the threaded rod 7, and a handle 9 is slidably installed on the surface of the threaded rod 7. The handle 9 is fixedly installed on the top of the cover 2. When the nut 8 rotates along the threaded rod 7, it locks the movable block 641 to one side of the handle 9 to maintain the engagement state between the insert plate 61 and the slot 62.

[0034] The device first fixes the equipment, attaches the suction plate 5 at the bottom of the sleeve 3231 to the smooth table surface, and rotates the adjusting rod 3233 by handwheel 4. The adjusting rod 3233 rotates relative to the sleeve 3231 and moves axially, pushing the piston 3232, which is slidably installed on the inner wall of the sleeve 3231, downward. The piston 3232 squeezes the air or liquid medium in the inner cavity of the sleeve 3231, and fixes the base 311 to the workbench.

[0035] The quick-release assembly 6 locks the cover 2 and the mixing tank 1 tightly to prevent material from splashing out during the crushing process. The operation drive unit 64 drives the two transmission rods 63 to move synchronously. The transmission rods 63 pull the insert plate 61 to slide along both sides of the cover 2, so that the end of the insert plate 61 is inserted into the corresponding slots 62 on both sides of the mixing tank 1, realizing the quick locking of the cover 2 and the mixing tank 1. When operating in the opposite direction, the insert plate 61 is removed from the slot 62, and the cover 2 and the mixing tank 1 are quickly separated, which facilitates feeding and discharging.

[0036] After the crushing mechanism 3 is started, the driver 312 installed at the bottom of the mixing tank 1 drives the crushing paddle 313 to rotate at high speed. The blades (three ring-shaped blades) on the surface of the crushing paddle 313 apply impact and shearing force to the shrimp larvae feed inside the mixing tank 1, gradually crushing the feed particles to the target fineness.

[0037] During the crushing process, the swing assembly 32 synchronously applies a periodic driving force to the mixing drum 1. The tops of the two side plates 321 are hinged to the two sides of the mixing drum 1, and the bottoms are fixed to the base 311, forming a swing support structure. When swinging is required, during the operation of the mixing drum 1, since the mixing drum 1 is hinged to the top of the side plates 321, the mixing drum 1 can swing back and forth around the hinge point relative to the side plates 321 under the reaction force generated by the rotation of the crushing paddle 313 and the manual assistance. At the same time, the bottom of the mixing drum 1 cooperates with the base 311 through the rotating seat, so that the mixing drum 1 can also rotate 360° around the vertical axis during the swinging process, which also facilitates the subsequent feeding.

[0038] The combined motion of oscillation and rotation causes the material in the mixing tank 1 to constantly change its spatial position and direction of movement. The material that was originally piled up at the bottom of the tank under the action of gravity is continuously thrown and rolled during the oscillation of the tank, migrating to the middle and upper parts of the tank cavity. The material that was originally attached to the tank wall is peeled off by the shear force of the wall during the rotation of the tank and re-participates in the crushing cycle. The material forms a complex motion trajectory of up and down rolling and circumferential flow in the tank. Material at different heights can continuously flow to replenish the bottom cutter head area, so that the material in all places can get a uniform crushing opportunity. When the crushing is completed, the driver 312 is turned off, and the cover 2 can be opened by the quick release component 6 to pour out the material.

[0039] Preferably, both the threaded rod 7 and the nut 8 are made of high-strength engineering plastic. This material has good corrosion resistance and is not prone to rusting under long-term contact with feed raw materials and humid environments. It can effectively prevent metal rust from contaminating the feed. At the same time, the threaded engagement of the threaded rod 7 and the nut 8 has a self-locking function. In the locked state, it can achieve self-locking by relying on the friction angle of the thread pair itself, preventing the cover 2 from loosening due to equipment vibration and ensuring the continuous and reliable sealing state during the crushing process.

[0040] Preferably, a control switch is provided on one side of the base 311. The control switch is electrically connected to the driver 312 via a wire and is used to control the opening and closing of the driver 312. A storage battery is provided inside the base 311. The storage battery is electrically connected to the control switch and the driver 312 via wires to provide power to the equipment, allowing the equipment to work independently without an external power source and facilitating flexible movement and use at the breeding site. The base 311 is also provided with an indicator light and a charging interface. The indicator light is electrically connected to the storage battery via a wire and is used to display the working status and power information of the equipment. The charging interface is electrically connected to the storage battery via a wire and is used to connect to an external power source to charge the storage battery (both are waterproof).

[0041] The driver 312 uses a brushless DC motor (HW-A-1020 DC stepless speed controller), and the speed is adjusted by a knob using the DC speed controller, achieving a wide range of speed adjustment from 1000 to 15000 r / min and constant torque control.

They are selected, installed and debugged by those skilled in the art according to the needs of use to ensure that all electrical appliances can work normally.
