Soil taking ring knife used for karst mountainous region and provided with positioning sleeve

Abstract

The invention discloses a soil taking ring knife used for a karst mountainous region and provided with a positioning sleeve. The soil taking ring knife comprises a knife wall, the outer side wall of the knife wall is fixedly connected with a spiral, a knife cover is fixedly connected to the top end of the knife wall, and a knife handle is fixedly connected to the upper portion of the middle of theknife cover; two symmetrical handles are fixedly connected to the side edges of the top end of the knife handle, the positioning sleeve movably sleeves the outer side of the knife handle, and a sleeve cover is fixedly connected to the bottom end of the positioning sleeve; a sleeve is fixedly connected to the lower portion of the outer side of the sleeve cover, a lantern ring is fixedly connectedto the bottom end of the sleeve, and a connecting sleeve base is fixedly connected with the lower portion of the outer side of the lantern ring. The positioning sleeve is arranged on the outer side ofthe ring knife, the ring knife is located in the positioning sleeve for positioning, and the outer side wall of the ring knife is provided with the spiral; by rotating the ring knife, the ring knifeis inserted into soil under the drive of the spiral; a pressing plate is arranged in the ring knife so that soil in the ring knife can be pushed out conveniently, and a good effect is achieved.

Description

technical field [0001] The invention relates to a soil-taking ring knife, in particular to a soil-taking ring knife used for a positioning sleeve in a karst mountain zone, and belongs to the technical field of soil sampling and analysis equipment. Background technique [0002] In karst areas, rocky desertification is becoming more and more serious. In order to study the changes of soil and environment, it is necessary to carry out sampling and analysis experiments on soil, and the ring knife is a tool for collecting soil in the field. Using the ring knife to collect soil can ensure soil quality. In order to obtain the physical properties such as soil bulk density and soil moisture content of the collected sample land. When collecting ring-knife soil in the field, take soil samples of different layers according to the experimental requirements, and use the ring-knife handle and hammer to drive the ring-knife into the soil at the same place. The existing ring knife is operate...

AI Technical Summary

Problems solved by technology

The existing ring knife is operated by hammering when inserting into the soil to take soil, which is not easy to operate, and the depth is not easy to control. Only other tools can be used to get out the soil in the ring knife, which will destroy the shape of the soil and have a negative impact on the subsequent data analysis; It is easy to damage the ring knife on the stone, this is a problem that needs to be solved
