[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0016] like Figure 1 FIG. 1 is a schematic diagram of a mechanical double anti-dropping device provided by an embodiment of the utility model, wherein the device comprises:

[0017] A feeding pipe 1, a moving pipe 4 and an equipment frame 9, wherein a bracket 3 is fixedly mounted on the equipment frame 9, a lifting control assembly is mounted on the bracket 3, the lifting control assembly is fixedly connected to the moving pipe 4, the moving pipe 4 is sleeved on the periphery of the feeding pipe 1, an upper sealing kit 2 is arranged between the top of the moving pipe 4 and the feeding pipe 1, the upper sealing kit 2 is used to close the gap between the feeding pipe 1 and the moving pipe 4, a barrel mouth sealing kit 7 is installed at the bottom of the moving pipe 4, the barrel mouth sealing kit 7 is used to seal the barrel mouth of the sample barrel 8, and the lifting control assembly is used to control the lifting of the moving pipe 4.

[0018] In the embodiment of the utility model, when in use, the sample barrel 8 is placed under the feeding pipe 1, and the moving tube 4 is sleeved on the outer periphery of the feeding pipe 1, and an upper sealing kit is provided between the moving tube 4 and the feeding pipe 1, so that the gap between the two is sealed. When feeding, the moving tube 4 is driven downward by the lifting control component until the barrel mouth sealing kit 7 under the moving tube 4 abuts against the outer edge of the barrel mouth of the sample barrel 8. At this time, the barrel mouth of the entire sample barrel 8 is wrapped by the moving tube 4, and the moving tube 4 and the feeding pipe 1 are also sealed. Therefore, the sample barrel 8 can only be connected with the feeding pipe 1, and the sealing of the sample barrel 8 is achieved. At this time, the material falling from the feeding pipe 1 can only enter the sample barrel 8. Since the overall sealing is achieved, the escape of dust and the loss of water in the material are avoided. After the feeding is completed, the lifting control component drives the moving tube 4 to rise. At this time, the barrel mouth sealing kit 7 is separated from the sample barrel 8, and the operation of switching the sample barrel can be performed.

[0019] like Figure 1 As shown, as a preferred embodiment of the utility model, the lifting control assembly includes a driving rack 6 and a gear, the gear is rotatably mounted on the bracket 3, a slide rail 5 is fixedly provided on the bracket 3, a slider is slidably provided on the slide rail 5, the driving rack 6 is fixedly connected to the slider, the driving rack 6 is meshed with the gear, the gear is driven by a driving member, a support frame is fixedly mounted on the driving rack 6, and the support frame is fixedly connected to the moving tube 4.

[0020] like Figure 1 As shown, as a preferred embodiment of the utility model, the driving member is a motor.

[0021] like Figure 1 As shown, as a preferred embodiment of the present utility model, the support frame and the driving rack 6 are connected by bolts.

[0022] like Figure 1 As shown, as a preferred embodiment of the present invention, the bracket 3 is fixedly connected to the equipment frame 9 by bolts.

[0023] In this embodiment, when it is necessary to control the lifting of the moving tube 4, the motor is started and the gear is driven to rotate by the motor. Since the gear is in meshing state with the driving rack 6, when the motor rotates forward or reversely, it will drive the driving rack 6 to rise or fall respectively. The driving rack 6 is fixedly connected to the moving tube 4, so it can drive the moving tube 4 to rise and fall.
