Embodiment

[0022] Example: Referring to Figure 1, the present invention is a new type of ultrasonic / sonic drilling sampler developed based on the first-order longitudinal vibration excited by the piezoelectric effect of a piezoelectric ceramic sheet. The device is composed of three parts: an ultrasonic driver 5, a free mass 7 and a solid drill rod 9. The ultrasonic driver 5 is a Ranjven vibrator, which is composed of a head 6, a tail 2, four piezoelectric ceramic plates 3, and five electrode plates 4, wherein the piezoelectric ceramic plate 3 and the electrode plates The arrangement of 4 is: four piezoelectric ceramic pieces 3 are stacked on the same polarity side in the axial direction (for example, the first one is opposite to the second positive electrode, the second one is opposite to the third negative electrode, and the third Opposite the fourth positive pole; or vice versa, the first one opposes the second negative pole, the second opposes the third positive pole, and the third oppose...

Abstract

The ultrasonic wave / sonic wave drilling sampler capable of obtaining sample in other planet consists of three main parts: ultrasonic driver, free mass block and drilling rod. The ultrasonic driver consists of screw in the head, clamping piezoelectric ceramic chip in the tail and electrode plate. The ultrasonic driver generates resonance in ultrasonic frequency to be coupled acoustically with the free mass block so as to make the free mass block collide the journal of the drilling rod reciprocally at sound wave frequency. The collision and impact energy is transmitted via the bit to the drilled matter and sample is obtained from the broken matter. The drilling sampler has the features of being light and portable, low power consumption, no need of circumferential holding moment, no motion pair, no need of lubricating and powerful drilling capacity.

Description

Technical field [0001] The invention relates to a small drilling sampler for drilling sampling, in particular to an ultrasonic / sonic drilling sampler. This kind of drilling sampler is not only suitable for deep space exploration of outer planets, but also can be used as a portable drilling sampling device for earth rock and mineral sampling. Background technique [0002] With the continuous development of human exploration of space, a small number of western developed countries have realized the dream of mankind landing on the moon, and are implementing landing exploration on Mars. However, in space exploration missions, when the exploration progresses to launching spacecraft and probes and soft landing on the surface of outer planets, drilling and sampling directly on the surface or below, or even deep, is an essential and important link. Whether it is to conduct online, real-time analysis of these directly drilled samples, or to bring the samples back to the earth for further r...
