Detailed Implementation

[0024] Please see Figures 1 to 6 The present invention provides the following technical solution:

The bottom of the horizontal plate 4 is provided with a vertical shaking mechanism. The left side of the box 1 is provided with a take-out port 2, and the left side of the box 1 is hinged to a door 3 that matches the take-out port 2. A handle is provided on the left side of the door 3.

[0026] The horizontal shaking mechanism includes a first cam 16, which is located on the right side of the placement box 9 near the top. A first rotating shaft 17 is fixedly connected to the top of the first cam 16 near the left side. A drive motor 19 is provided on the top of the box 1 near the right side. The top of the first rotating shaft 17 is fixedly connected to the power output end of the drive motor 19. The drive motor 19 drives the first rotating shaft 17 to rotate. The rotation of the first rotating shaft 17 drives the first cam 16 to rotate. With the cooperation of the movable plate 6, the crossbar 14 and the compression spring 15, the placement box 9 is driven to shake horizontally, thereby allowing the test tube to be shaken horizontally.

[0027] The vertical shaking mechanism includes a second cam 20, which is located at the bottom of the horizontal plate 4. A second rotating shaft 21 is fixedly connected to the right side of the second cam 20 near the top, and the right end of the second rotating shaft 21 is rotatably connected to the right side wall of the inner cavity of the housing 1. A driven bevel gear 22 is sleeved and fixedly connected to the outer wall of the second rotating shaft 21, and a transmission bevel gear 23 meshes with the top of the driven bevel gear 22.

The rotation of the second rotating shaft 21 drives the second cam 20 to rotate, and the rotation of the second cam 20 drives the horizontal plate 4 to shake in the vertical direction, thereby vertically shaking the test tube.

[0028] Hollow cylinders 26 are provided at the four corners of the bottom of the horizontal plate 4, and the bottom end of the hollow cylinder 26 is fixedly connected to the bottom of the inner cavity of the box 1. A sliding column 27 is slidably connected to the inner cavity of the hollow cylinder 26, and a sliding rod 28 is fixedly connected to the top of the sliding column 27. A through hole adapted to the sliding rod 28 is opened at the top of the hollow cylinder 26, and the top end of the sliding rod 28 passes through the inner cavity of the through hole and is fixedly connected to the bottom of the horizontal plate 4. A first spring 29 is sleeved on the outer wall of the sliding rod 28, and the two ends of the first spring 29 are fixedly connected to the top of the inner cavity of the hollow cylinder 26 and the top of the sliding column 27, respectively. When the horizontal plate 4 moves upward, the sliding column 27 can be driven by the sliding rod 28 to overcome the resistance of the first spring 29 and move vertically, thereby slowing down the horizontal plate 4 and preventing the test tube in the box 9 from vibrating too much.

[0029] A connecting plate is fixedly connected to the left side of the movable plate 6, and a through hole is provided on the connecting plate. A T-shaped rod 30 is slidably connected to the inner cavity of the through hole, and a second spring 31 is sleeved on the outer wall of the T-shaped rod 30. The two ends of the second spring 31 are fixedly connected to the connecting plate and the T-shaped rod 30 respectively. An insertion hole 32 that matches the T-shaped rod 30 is provided at the bottom of the support plate 8 near the left side, and the longest end of the T-shaped rod 30 is inserted into the inner cavity of the insertion hole 32. By pulling the T-shaped rod 30 to overcome the resistance of the second spring 31 and move it downward, it can be disengaged from the inner cavity of the insertion hole 32, thereby pulling the support plate 8 horizontally to the left to the pick-up and drop-off port 2, thereby improving the convenience of the staff to pick up and drop off the test tubes.

[0030] The sealing mechanism includes two electric telescopic rods 12, which are respectively located on the front and rear sides of the placement box 9. The power ends of the two electric telescopic rods 12 are fixedly connected to the same cover plate 13, and the bottom of the cover plate 13 is fixedly connected to a sealing gasket 35. By activating the electric telescopic rods 12, the cover plate 13 is pulled vertically downward, which causes the sealing gasket 35 to seal the top of the test tube, thereby preventing the leakage of food and reaction solution inside the test tube during shaking.

[0031] Working Principle: When in use, pulling the handle causes the door 3 to flip outwards, opening the loading / unloading port 2. The operator pulls the T-shaped rod 30 to overcome the resistance of the second spring 31, moving it downwards and disengaging it from the inner cavity of the insertion hole 32. Then, the support plate 8 is pulled horizontally to the loading / unloading port 2, facilitating the placement of test tubes containing food through the fixing hole 11 into the placement box 9. After the test tubes are placed, the placement box 9 is pushed back to its original position, and the T-shaped rod 30 is inserted into the inner cavity of the insertion hole 32 for locking. Next, the two electric telescopic rods 12 are activated, pulling the cover plate 13 vertically downwards, thereby pressing the sealing gasket 35 against the top of the test tube. Combined with the rubber gasket 37, this allows for elastic tightening of the test tube. When the drive is activated... Motor 19 drives the first rotating shaft 17 to rotate, which in turn drives the first cam 16 to rotate. The rotation of the first cam 16 pushes the placement box 9 to move back and forth, thereby horizontally shaking the test tubes in the placement box 9. Meanwhile, the rotation of the first rotating shaft 17 drives the transmission gear 18 to rotate, which in turn drives the driven gear 25 to rotate. The rotation of the driven gear 25 drives the transmission shaft 24 to rotate, which in turn drives the second rotating shaft 21 to rotate through the meshing of the transmission bevel gear 23 and the driven bevel gear 22. The rotation of the second rotating shaft 21 drives the second cam 20 to rotate, which pushes the horizontal plate 4 to shake up and down, thereby vertically shaking the test tubes in the placement box 9 and improving the mixing efficiency of the food and the reaction solution.
