Stretchable bionic sampler

Abstract

The invention relates to the field of space star sampling, and concretely relates to a stretchable bionic sampler. An expansion and delivery mechanism is provided with a strip steel reel, a transport roller transmission mechanism, and two transport rollers, the end portion of the strip steel reel and an output shaft of an expansion driving motor are connected, a strip steel is connected to a sampling drill and winds the strip steel reel, the strip steel is transported by the transport rollers, wherein an active transport roller is driven by the expansion driving motor to rotate, and the expansion driving motor transmits torque through a transport roller delivery mechanism. The sampling drill comprises a drill casing, a drill bit, a guide pipe, a reciprocate driving mechanism, and a sampling apparatus; the rear end of the drill casing and the strip steel are fixedly connected, the rear segment of the drill bit is arranged in the drill casing, the front segment of the drill bit is arranged outside the drill casing and is provided with pawls; the guide pipe is arranged in the drill casing, the rear segment of the drill bit is sleeved on the guide pipe, the rear segment of the guide pipe is provided with a reciprocate driving mechanism for driving the drill bit to move, and the front end of the drill bit is provided with the sampling apparatus which is fixedly connected to the front end of the guide pipe. The sampler is designed based on a bionics principle, so that drilling and sampling can be carried out at the same time.

Description

technical field [0001] The invention relates to the field of space star sampling, in particular to an extendable bionic sampler. Background technique [0002] With the vigorous development of my country's aerospace industry, the exploration of other stars besides the moon is also gradually put on the development agenda. An important task in the space star detection project (including my country's Chang'e project) in the world is the sampling and recovery of stars. By analyzing the composition of stars, it can increase human's understanding of the evolution of stars, and it can also be used to find new ones. resource. In the existing technology, the most commonly used method of sampling is the rotary drill, and its technology development has been very mature, but in the unknown space environment, factors such as cutting heat are likely to cause the drill to fail, so that it cannot work normally. In addition, the rotary drill requires a special The equipment provides enough p...

Problems solved by technology

In the existing technology, the most commonly used method of sampling is the rotary drill, and its technology development has been very mature. However, in the unknown space environment, factors such as cutting heat may easily cause the drill to fail, so that it cannot work normally. In addition, the rotary drill requires special equipment. The equipment provides enough positive pressure to achieve drilling, which will also increase the difficulty of launch, and the launch cost is higher
