Sampling and collection integrated spiral continuous self-contained collector

Abstract

The invention relates to a sampling and collection integrated spiral continuous self-contained collector, which comprises a rotating shaft, a motor, a transmission gear pair and a sample collection cavity, wherein the rotating shaft is provided with a contact probe, a spiral wing and a shaft collar; the diameter of the middle cavity body of the sample collection cavity is larger than that of the upper part of the sample collection cavity; the upper part of the sample collection cavity is provided with a collection cavity upper platform; the collection cavity upper platform is provided with a hinge hole and a motor; the rotating shaft is arranged in an inner cylinder of the sample collection cavity; the upper part of the rotating shaft is provided with a transmission cone gear; a cavity cover is in threaded connection with the sample collection cavity; and a main shaft of the motor is provided with a transmission gear pair consisting of a motor shaft gear and the transmission cone gear. During sampling, the hinge hole and the motor are connected with a mechanical arm and a power source for control operation respectively; the control motor drives the cone gear pair to rotate; when the rotating shaft rotates, a sample is shoveled by the spiral wing; and the sample enters the sample collection cavity along with upward thrust force of the spiral wing. The collection device integrates sampling and collection, has a simple structure, a short transmission chain and low power consumption, and can be combined with the operating mechanical arm for sampling on the moon or in environments which are not suitable for human operation.

Description

technical field [0001] The invention relates to a harvesting integrated spiral continuous self-contained collector, in particular to a collector used in the exploration and sampling of the moon and other planets, or sampling in an environment that is not suitable for human work. Background technique [0002] With the development of deep space exploration technology by various aerospace powers, the moon will become another international research hotspot after the high seas and Antarctica, and the Chinese will also be able to achieve the goal of space exploration in the near future. The unique minerals and energy on the moon are important supplements and reserves for the earth's resources. Therefore, as the demand for deep space exploration and other explorations further increases, the requirements for samplers will also further increase. The continuous change of the detection sampling environment also requires samplers of different types and structures to adapt. In recent ye...

Problems solved by technology

At present, the existing collectors for collecting samples in deep space, such as a collector named TERPS based on the NASA Mars Exploration Program, and the ISAD sampler designed by the American "Bee Robotics" company, all have complex structures and high power consumption. The problem

Some studies have been done on the lunar surface sampler in our country. The sampling method of the sampler is mainly combined with drilling and surface sampling. Very loose and dry samples such as soil, because of the combination of drilling and surface sampling, the structure of the sampler is more complicated

All in all, among the existing various types of samplers, none are fully suitable for my country's lunar exploration projects. Based on the lander, no lunar vehicle and no manned conditions, the lunar surface sampling task is combined by drilling and surface sampling. Completed Meter Sampling End Sampler
