Description

휴대용 토양채취장치{Portable soil sampling device}Portable soil sampling device {Portable soil sampling device}

본 발명은 휴대용 토양채취장치에 관한 것으로, 구체적으로는 별도의 동력발생장치를 필요로 하지 않음과 더불어 휴대가 용이하여 운반 및 작업이 편리하면서도 토양의 채취시 토양이 유실되는 것을 억제할 수 있도록 하는 휴대용 토양채취장치에 관한 것이다.The present invention relates to a portable soil collection device, and specifically, does not require a separate power generator and is easy to carry, so that it is convenient to carry and work while suppressing the loss of soil during soil collection. It relates to a portable soil collection device.

일반적으로 토양을 조사하기 위한 토양시료의 채취장치는 토양에 시추공을 형성하여 토양의 시료를 채취하는 것으로, 토목공사 등에서 토양에 알맞은 최적의 설계조건을 위해서는 반드시 수행되어야 하며, 이러한 토양 시추조사를 통해 토양의 물리 화학적 특성 및 구조 등을 다양하게 조사하고 있다.In general, a soil sample collection device for soil investigation is to collect a soil sample by forming a borehole in the soil, which must be performed for optimal design conditions suitable for the soil in civil engineering works. The physical and chemical properties and structure of soil are investigated in various ways.

그리고, 상술한 토목공사 등에서 요구하는 최적의 설계조건을 위해서 뿐만 아니라, 외부 환경에 의해 쉽게 오염될 수 있는 토양의 오염도를 분석하기 위해서도 토양의 채취는 필수적으로 요구될 수 있다.In addition, soil sampling may be required not only for the optimal design conditions required for the above-described civil engineering work, but also for analyzing the contamination level of soil that can be easily contaminated by the external environment.

이러한 토양시료의 채취장치는 인력 또는 동력수단을 이용해 타격 또는 회전력을 토양에 전달시켜 시료채취관이 지층 내부로 관입해가면서 시료채취관 내부에 관입된 깊이 만큼의 토양이 채워지게 되는데, 이때 시료채취관을 지상으로 뽑아내 채취된 토양시료를 외부에서 확인할 수 있는 것이다.Such a soil sample collecting device transmits impact or rotational force to the soil using manpower or power means, so that the sampling tube penetrates into the stratum and fills the soil as much as the depth of penetration into the sampling tube. The pipe is pulled out to the ground and the collected soil sample can be checked from the outside.

종래의 토양채취장치는 장치를 회전시켜 하부에 장착된 오거날에 토양을 담아 채취하게 되는데, 이 경우 토양의 회수시 유실되거나, 이로 인해 목적하는 양보다 적은 양의 토양이 채취될 수밖에 없는 문제가 있었다.In the conventional soil collection device, the soil is collected by rotating the device to collect the soil on the auger blade mounted on the lower part. In this case, the soil is lost during recovery, or due to this, a smaller amount of soil than the intended amount is inevitable to be collected. there was.

특히, 사질토(모래 성분이 많은 흙)의 경우, 종래의 토양채취장치 오거날에 토양이 고정되지 않아, 유실되는 토양의 양이 많았고, 종래의 토양채취장치는 동력발생장치의 구비를 필요로하기 때문에 휴대가 어려워 운반이나 작업이 편리하지 않은 문제도 있었다.In particular, in the case of sandy soil (soil with a large amount of sand), the soil was not fixed to the blade of the conventional soil extractor, so a large amount of soil was lost, and the conventional soil extractor required a power generator. Therefore, there was also a problem that it was difficult to carry and not convenient to carry or work.
