Planetary soil transfer and dust-proof seal device

Abstract

The invention discloses a planetary soil transfer and dust-proof seal device. The device comprises a substrate, a soil transfer mechanism and a dust-proof seal mechanism, wherein the planetary soil transfer mechanism comprises a guide rail arranged between two sliding brackets; a stroke motor is arranged on the substrate which can slide reciprocally along the guide rail; a first gear which is engaged with a rack is arranged on the rotating shaft of the stroke motor; a turning plate is arranged in a hopper; the rotating shaft of the turning plate is provided with a second gear which is engaged with a triggering rack; the dust-proof seal mechanism comprises a first motor seat, a pressure spring, a motor and a rotating cover, wherein a voice coil linear motor is arranged in the first motor seat; the pressure spring is positioned at the bottom of the voice coil linear motor; the motor is connected with the rotating shaft; the rotating cover is arranged on the rotating shaft and is in clearance fit with the rotating shaft; one end of the rotating cover is provided with an opening for planetary soil to pass; the other end is a seal cover; a force transmission rod is arranged on the seal cover; and a seal cup is arranged on a cup seat which is arranged below the rotating cover. The device has the characteristics of small volume, light weight, low power consumption, less required motors, dust prevention and sealing.

Description

technical field [0001] The invention relates to a planetary soil transfer and dustproof sealing device, which is suitable for sample transfer and dustproof sealing after the soil is sampled on the moon and other celestial bodies. Background technique [0002] With the rapid development of automatic control and robot technology, humans are increasingly using robots and other automated equipment to collect rock and soil on the surface of planets in deep space objects. Lightweight, low power consumption and reliable machinery and equipment to complete various tasks. The second phase of my country's Chang'e lunar exploration project needs to sample and analyze the lunar soil to measure the helium 3 concentration in the shallow lunar soil. After the sampler takes out the lunar soil, it is necessary to transfer the collected lunar soil to a container through some methods, and after sealing and heating, the volatile gas is sent to the gas analysis instrument for analysis through...

[0003] The process of transferring the planetary soil collected by the soil sampler to the sealing of the container requires complex mechanical devices to complete

At present, the transfer and sealing process in foreign countries mainly uses multi-link robotic arms to transfer the planetary soil to the analytical instrument, and the analytical instrument performs sealing and analysis. The transfer mechanism is separated from the sealing mechanism, which increases the overall volume and weight. To complete this process, two sets of devices need to be coordinated. work, and the dust-proof sealing of the sealing port cannot be guaranteed, which increases the cost of vacuum sealing, and there is no disclosure of planetary soil transfer and sealing devices in China.
