Description

Technical Field

[0001] This utility model relates to the field of food safety technology, specifically to a crushing and sampling device for food quality and safety testing. Background Technology

[0002] A grinder is needed when sampling and testing food safety. A laboratory food grinder is a device specifically designed for laboratory environments to grind, pulverize, and refine food raw materials. This type of grinder has wide applications in food science, drug development, agricultural research, and other fields, and can meet the high requirements for sample fineness, purity, and processing efficiency.

[0003] This utility model provides a solid food crushing and sampling machine, relating to the technical field of food crushing and sampling machines. The utility model includes a crusher and a disassembly structure. A bottom cover is slidably connected to the bottom surface of the crusher, and a top cover is also provided on the top surface of the crusher. The bottom cover has a disassembly structure on its surface and a protective structure on its bottom surface. A handle is fixedly connected to the side of the top cover, and a motor is fixedly connected to its surface. A switch button is provided on the surface of the motor. A connecting rod is fixedly connected to the bottom surface of the motor, and crushing blades are rotatably connected to the bottom surface of the connecting rod. The disassembly structure includes a connecting column and an adjusting rod. A connecting column is fixedly connected to the side wall of the crusher, and an installation groove is provided on the surface of the connecting column. This utility model solves the problem that food crushed pieces easily stick to the inner wall of the food crushing and sampling machine during use, making cleaning difficult.

A rotating rod 4 is provided on the right side of the transmission box 3. The left side of the rotating rod 4 extends into the interior of the transmission box 3 and is movably connected to the inner wall of the transmission box 3 through a bearing. A turntable 5 is fixedly connected to the surface of the rotating rod 4. Two pull rods 6 are fixedly connected to the right side of the turntable 5. A traction rod 7 is sleeved on the surface of the pull rod 6. A moving plate 8 is connected to the outside of the traction rod 7 through a pin. The surface of the moving plate 8 is slidably connected to the inner wall of the transmission box 3. A connecting plate 9 is fixedly connected to the outside of the moving plate 8. The outside of the connecting plate 9 extends through to the outside of the transmission box 3 and is fixedly connected to a pressure plate 10. The end of the pressure plate 10 away from the connecting plate 9 extends to the surface of the crusher 1.

[0018] refer to Figure 4 A rotating block 11 is fixedly connected to the right side of the rotating rod 4. A clamping plate 12 is connected to the inside of the transmission box 3 by a pin. A clamping block 13 is fixedly connected to the bottom of the clamping plate 12. The bottom of the clamping block 13 extends into the inside of the rotating block 11 and contacts the inner wall of the rotating block 11.

[0019] As a technical optimization of this utility model, by setting the rotating block 11, the locking plate 12 and the locking block 13, the rotating rod 4 can be limited, so as to prevent the rotating rod 4 from rotating on its own during use.

[0020] refer to Figure 4 The transmission box 3 has two guide rods 14 fixedly connected horizontally inside. The inner side of the guide rods 14 passes through the moving plate 8 and is slidably connected to the moving plate 8.

[0021] As a technical optimization of this utility model, by setting the guide rod 14, the movable plate 8 can be guided to prevent the movable plate 8 from tilting and getting stuck during the movement.

[0022] refer to Figure 4 Two blocks 15 are provided on the inner side of the movable plate 8, and the outer side of the blocks 15 is fixedly connected to the inner side of the guide rod 14.

[0023] As a technical optimization of this utility model, by setting the stop 15, the movable plate 8 can be limited, thus preventing the movable plate 8 from detaching from the guide rod 14.

[0024] refer to Figure 2 Limiting rods 16 are fixedly connected to both the front and rear sides of the crusher 1. The limiting rods 16 pass through the pressure plate 10 and are slidably connected to the pressure plate 10.

[0025] As a technical optimization of this utility model, by setting the limiting rod 16, the pressure plate 10 can be guided, preventing the pressure plate 10 from shaking randomly and improving the stability of the pressure plate 10 when moving.

[0026] refer to Figure 4 A spring return device 17 is fitted on the surface of the guide rod 14. The outer side of the spring return device 17 is fixedly connected to the inner side of the movable plate 8, and the inner side of the spring return device 17 is fixedly connected to the outer side of the stop block 15.

[0027] As a technical optimization of this utility model, by setting the rebound device 17, the movable plate 8 can be moved inward automatically, thereby improving the performance of the movable plate 8.

[0028] The working principle and usage process of this utility model are as follows: First, place the food into the crusher 1. After placement, flip the cover plate 2 downwards to cover the crusher 1. After flipping, flip the clamping plate 12 and clamping block 13 upwards using the pin rod, moving the clamping block 13 away from the rotating block 11. After this, the user rotates the rotating block 11, causing the rotating rod 4 to rotate. The rotating rod 4 then rotates the turntable 5, which in turn rotates the pull rod 6. During rotation, the pull rod 6 pulls the traction rod 7 inwards, causing the moving plate 8 to move inwards. The moving plate 8 then moves the pressure plate 10 inwards, pressing the pressure plate 10 against the top of the cover plate 2. After this pressing, flip the clamping plate 12 and clamping block 13 downwards again, limiting the movement of the rotating block 11. Finally, to remove the crushed food for sampling, reverse the above steps.

[0029] In summary, this food quality and safety testing crushing and sampling device, by setting up a pressure plate 10, can fix the cover plate 2, preventing vibration and collision of the cover plate 2; by setting up a rotating rod 4, a turntable 5, a pull rod 6, a traction rod 7, and a moving plate 8, it can drive the pressure plate 10 to move back and forth, improving the practicality of the moving plate 8; by setting up a rotating block 11, a clamping plate 12, and a clamping block 13, it can fix the rotating rod 4, preventing the rotating rod 4 from rotating on its own, thus having the advantage of easy fixation. This solves the problem that most crusher cover plates are placed directly on top of the crusher, which makes the cover plate prone to up and down vibration during crushing, causing abnormal noise in the crusher and reducing the practicality of the crusher.
