Transferring and dustproof sealing device for planet soil

Abstract

The invention provides a transferring and dustproof sealing device for planet soil. The device is composed of a base plate, a soil transferring mechanism and a dustproof sealing mechanism. The soil transferring mechanism includes a guide rail disposed between two sliding supports, a sliding base plate which can move back and forth along the guide rail, a lead screw with one end being connected to a stroke motor while the other end going through the sliding base plate, and a funnel which is provided with an inner turnover panel and can move back and forth along with the sliding base plate. The dustproof sealing mechanism includes a second motor base fixedly equipped with a pressure motor and a slide bar, a forcing bar with both ends being connected to the slide bar in a sliding manner, a third motor base equipped with a pressure motor connecting with a rotary shaft, a rotary cover which is installed on the rotary shaft and is in clearance fit with the rotary shaft, a sealing cup and a cup holder disposed under a dust ring, wherein one end of the rotary cover is provided with an opening for the passage of soil while the other end of the rotary cover is a sealing cover provided with a dowel bar. The device with the transferring mechanism and the rotary sealing mechanism in the invention has the characteristics of small size, low weight, low power consumption, low demand on motor number and dustproof sealing.

Description

technical field [0001] The invention relates to a planetary soil transfer and dust-proof sealing device, which is suitable for sample transfer and dust-proof sealing after the soil is sampled on celestial bodies such as the moon. 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 soil collected by the planetary soil sampler to the sealed 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.
