Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] First Embodiment

[0021] Please see Figures 1-3 This utility model provides a technical solution: an integrated food sample crushing, homogenizing and conveying device, including a tank body 1, a tank cover 2 detachably provided on the top of the tank body 1, and a disassembly assembly provided between the tank cover 2 and the side wall of the tank body 1.

[0022] The side wall of tank body 1 is provided with several stationary knife teeth at intervals.

[0023] The bottom center of the can lid 2 is rotatably provided with a rotating shaft 9. A moving blade disc 10 is fixedly connected to the upper part of the surface of the rotating shaft 9. Several emulsification heads 11 for homogenizing samples are fixedly connected to the middle part of the rotating shaft 9. The bottom of the can body 1 is a conical barrel 4. Several spiral conveying blades 12 are fixedly connected to the bottom of the surface of the rotating shaft 9.

[0024] In this embodiment, at least one movable cutter disc 10 is fixedly connected to the upper part of the rotating shaft 9. The movable cutter disc 10 and the stationary cutter teeth fixed on the inner wall of the tank body 1 are arranged alternately and cooperate with each other to form a high-speed shearing zone. When a large sample is put into the tank lid 2 through the feed port, it is first cut and crushed in this area to complete the primary crushing.

[0025] Several emulsifying heads 11 are fixedly connected to the middle of the rotating shaft 9. The emulsifying head 11 is part of the rotor-stator structure. When its rotor part rotates at high speed, it forms a strong mechanical shearing and cavitation effect with the surrounding fixed stator (or the narrow gap formed by the rotor part and the inner wall of the tank 1), which refines and emulsifies the sample after primary crushing, ensuring that the sample reaches a high degree of uniformity.

[0026] The bottom of the tank 1 is designed as a conical barrel 4, which facilitates the gathering of materials towards the center. At the bottom of the rotating shaft 9, several spiral conveying blades 12 are fixedly connected. The outer edge of the spiral conveying blades 12 is adapted to the inner wall of the conical barrel 4, and their rotational motion can continuously squeeze and push the homogenized sample downwards.

[0027] The drive unit starts, causing the rotating shaft 9 and all components integrated thereon to rotate synchronously at high speed. After the sample is added from the feed inlet, it successively undergoes cutting in the crushing zone, fine emulsification in the homogenizing zone, and finally is forcibly pushed towards the discharge pipe 5 by the spiral conveying blades 12 in the conveying zone and discharged. The entire process is completed continuously and automatically in a closed space, which is efficient and hygienic.

[0028] Please see Figure 1 Furthermore, a feed hopper 7 is provided at the top of the tank body 1, a discharge pipe 5 is provided at the bottom of the tank body 1, and a solenoid valve 6 is provided on the surface of the discharge pipe 5.

[0029] In this embodiment, the sample is added from the feed hopper 7. After the device is started, the drive motor 8 drives the rotating shaft 9 to rotate, and the sample undergoes crushing and homogenization processes in sequence. After the processing is completed, the control system issues a command to open the solenoid valve 6, and at the same time, the spiral conveyor blades 12 forcefully and quantitatively discharge the final product through the discharge pipe 5. After processing is completed, the quick-release clamp 3 can be loosened, and the entire rotating shaft 9 module can be pulled out for cleaning.

[0030] Please see Figure 1 Furthermore, a viewing mirror 3 is provided on the surface of the tank body 1, and a support column 19 is provided at the bottom of the tank body 1, with an anti-slip pad 20 fixedly connected to the bottom end of the support column 19.

[0031] In this embodiment, the fluoroscopy lens 3 enables visualization of the processing. The operator can monitor the sample status in real time without stopping or turning on the equipment, facilitating precise control of processing time and quality. This is an important design feature that enhances process controllability and operational intelligence.

[0032] Support column 19 ensures the structural stability of the equipment under high-speed operation;

[0033] The anti-slip mat 20 effectively prevents equipment displacement caused by vibration during operation, reduces safety risks, and reduces noise and vibration transmission.

[0034] Please see Figure 2 Furthermore, a motor 8 is vertically mounted on the top of the can lid 2. The output shaft of the motor 8 is fixedly connected to the top end of the rotating shaft 9. A threaded rod 21 is mounted on the top end of the rotating shaft 9. The output shaft of the motor 8 has a threaded groove that is threadedly connected to the threaded rod 21.

[0035] In this embodiment, the connection between the motor 8 and the shaft 9 adopts a quick-release structure:

[0036] By screwing the threaded rod 21 into the threaded groove of the output shaft of the motor 8, the motor 8 and the rotating shaft 9 can be synchronously, coaxially, and stably connected. This connection method not only transmits torque reliably, but more importantly, when cleaning or maintenance is required, the rotating shaft 9 assembly can be easily unscrewed from the motor 8, realizing the rapid separation of the power unit and the working unit.

[0037] Please see Figure 4 Furthermore, the disassembly assembly includes several mounting blocks 15 and several support blocks 13. The mounting blocks 15 are spaced apart along the circumferential direction of the can lid 2 on the side wall of the can lid 2, and the support blocks 13 are spaced apart along the side wall of the can body 1 on the top of the side wall of the can body 1. Each mounting block 15 has a protrusion 16 at its bottom, and each support block 13 has a groove 14 that matches the protrusion 16. The side wall of the can lid 2 is provided with several hooks 17, and the side wall of the can body 1 is provided with several latches 18 that can be engaged with the hooks 17.

[0038] In this embodiment, after the protrusion 16 falls into the groove 14, the can lid 2 is rotated so that the hook 17 is turned into the latch of the lock 18. Then, the lock 18 is pulled to lock the hook 17, thereby firmly pressing the can lid 2 and the can body 1 together. This structure enables the can lid 2 to be opened and closed quickly, with a large locking force and reliable sealing. When it is necessary to clean the moving blade disc 10, the emulsifying head 11, and the spiral conveyor blades 12, the can lid 2 can be removed directly, and then the rotating shaft 9 can be removed from the motor 8. This greatly improves the efficiency of equipment loading, unloading, and maintenance, and reduces the labor intensity of operators.

[0039] The working principle and usage process of this utility model are as follows: After the utility model is installed, rotating the can lid 2 causes the hook 17 to engage with the lock 18 and lock it in place, firmly sealing the can lid 2 to the can body 1. The drive motor 8 is started, driving the rotating shaft 9 and all its integrated components to rotate synchronously at high speed. The sample first enters the crushing zone, where the high-speed rotating moving blade 10 and the stationary blade teeth fixed to the inner wall of the can body 1 perform interlaced shearing, quickly cutting and crushing large pieces of sample, completing the primary crushing. The sample after primary crushing enters the homogenization zone under the push of gravity and subsequent materials, and the homogenized sample falls into the homogenization zone. At the bottom of the conical barrel 4, the control system commands the solenoid valve 6 to open. The homogenized sample is pushed by the spiral blades and discharged quantitatively and thoroughly through the discharge pipe 5. It can directly enter the sample collection bottle or subsequent automated production line. After processing, the motor 8 is turned off. First, loosen the lock 18 of the disassembly component, rotate and open the tank cover 2, and then rotate the shaft 9 in the opposite direction. The entire shaft 9 assembly, which integrates the moving blade disc 10, the emulsifying head 11 and the spiral conveying blades 12, can be removed from the motor 8 for thorough cleaning and disinfection, which greatly facilitates maintenance.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
