Abstract

A ground drilling device for installing observation probe tubes, including a ground steel pipe and a bottom plate. Two vertical support lugs are arranged in parallel above the bottom plate. There is a rotatable support between the two support lugs. Guide sleeve, the ground-entry steel pipe is arranged in the guide sleeve and supported by the guide sleeve. The ground-entry steel pipe is inserted into the ground along the angle set by the guide sleeve and brought out of the soil to form a hole suitable for installing an observation probe. The ground drilling device of the present invention uses downward pressure to gently cut through the soil. It has a simple structure and is easy to operate without disturbing the soil and plant roots. Furthermore, the ground drilling device of the present invention provides a base plate and a guide sleeve that can stabilize the drilling angle. tube, the drilling process will not cause directional deviation, and the required drilling angle can be easily set. The holes drilled are straight, the wall is smooth, the disturbance to the soil and root system is small, the diameter of the hole is uniform, and it is consistent with the diameter of the probe tube. Moderate contact is beneficial to obtain more accurate measurement results.

Description

technical field

[0001] The invention relates to the technical field of ground installation of soil observation equipment, in particular to an installation device for experimental instruments, in particular to a ground drilling device for measuring soil moisture, root system density and other observation probes. Background technique

[0002] Soil tensiometer, time-domain reflectometry (TDR), and root window technology are commonly used test devices and technologies for studying soil moisture and plant root ecology. The key to the installation of the instruments is the installation of the instrument probes that are in direct contact with the soil. The installation of the probe tube is currently mainly to use an earth drill to drill a hole whose depth and size match the length and diameter of the probe tube, and then insert the probe tube into the hole. This method mainly has several limitations and problems in actual operation: first, the soil drill mainly uses manpower to dri...
