The driving mechanism 22 is used to drive the working platform 211 to flip in the direction of the material recovery device 3, so that the table surface has a slope. In this process, the material on the platform is automatically slid into the material recovery device under the action of gravity, which can greatly simplify the material recovery process, so that the experimenter no longer needs to manually carry and transfer the material, thereby saving precious time and energy.

[0024] The driving mechanism 22 includes a lifting member 221 and a driver 222 that drives the lifting member 221 to rise or fall in the height direction. The top of the lifting member 221 abuts against the bottom side of the working platform 211. One side of the working platform 211 is hinged in the cabinet 1. When the driver 222 drives the lifting member 221 to rise and press the working platform 211, the working platform 211 flips around the hinge axis and the inclination angle increases. When the driver 222 drives the lifting member 221 to lower, the working platform 211 flips around the hinge axis and the inclination angle decreases. The driving mechanism 22 of the lifting table type fume hood is the core component of the whole equipment. Its working principle and structural design bring significant convenience of operation and work efficiency improvement to the experimenters. Specifically, the driving mechanism 22 consists of a lifting member 221 and a driver 222. The two parts work together to realize the lifting and lowering of the working platform 211 and the adjustment of the tilt angle. The working platform 211 is provided with lugs 2111 on both sides of the opposite sides. The platform mechanism 21 also includes an articulated shaft 212 for passing through the lugs 2111. Both ends of the articulated shaft 212 are connected to the cabinet body 1. The top of the lifting member 221 is tightly abutted against the bottom side of the working platform 211, ensuring the effective transmission of force and the stable lifting and lowering of the platform.

[0025] Side baffles 2112 protruding in the height direction are provided on opposite sides of the working platform 211 to limit the moving direction of the materials on the working platform 211 to ensure that the materials will not leak sideways during the sliding process.

[0026] The driver 222 is a cylinder. The advantages of using a cylinder include fast response speed, strong load-bearing capacity, high energy efficiency, strong adaptability, simple maintenance and high safety.

[0027] The cabinet 1 is provided with an experimental operation area 11 and a material processing area 12. The material processing area 12 is located at the lower side of the experimental operation area 11. The operation platform 211 is provided in the experimental operation area 11.

The drop opening 111 is used for allowing materials sliding on the operation platform 211 to fall into the material processing area 12. The material recovery device 3 includes a collection mechanism 31 and a feeding mechanism 32. The collection mechanism 31 includes at least a collection hopper 311. The upper end of the collection hopper 311 is connected to the drop opening 111, and the lower end of the collection hopper 311 is arranged opposite to the feeding mechanism 32. Among them, the inner diameter of the collection hopper 311 gradually narrows from the upper end to the lower end. This design can make the materials fall more concentratedly from the feeding mechanism 32 for the next step of processing.

[0028] The feeding mechanism 32 at least includes a movable conveyor belt 321, and the collecting mechanism 31 also includes a discharge pipe 312 connected to the lower end of the collecting hopper 311, and the pipe mouth of the discharge pipe 312 faces the conveyor belt 321. After passing through the collecting hopper 311, the material falls onto the conveyor belt 321 through the discharge pipe 312.

[0029] The cabinet 1 is also provided with a window assembly 13, which includes a fixed window 131 and a movable window 132 that are hingedly arranged.
