Embodiment Construction

[0031] Combine below Figure 1 to Figure 3 , the present invention is further described:

[0032] Such as figure 1 As shown, an automatic sampler that can simultaneously use multiple ring cutters for sampling includes a female rod 3, an expansion rod 4 and a drill bit 7. The drill bit 7 is installed at the bottom of the female rod 3, and the female rod 3 is connected to the expansion rod 4 through the driving device. connection, the driving device drives the female rod 3 and the drill bit 7 to move up and down along the axial direction, the female rod 3 is provided with multiple slots at different positions along the axial direction, and a ring cutter is placed in each slot, and multiple ring cutters realize Simultaneous automatic sampling of soil at different soil depths.

[0033] Specifically, the driving device includes a micromotor 6, a rotating screw 14 and a moving nut 15. One end of the rotating screw 14 is connected to the micromotor 6, and the other end of the rotat...

Abstract

The invention relates to an automatic sampler capable of sampling by simultaneously using multiple cutting rings. The automatic sampler comprises a main rod (3), an expansion rod (4) and a drill bit (7), wherein the drill bit (7) is mounted at the bottom end of the main rod (3); the automatic sampling device is characterized in that the main rod (3) is connected with the expansion rod (4) by a driving device, the driving device drives the main rod (3) and the drill bit (7) to move axially up and down, multiple clamping slots are axially formed in different positions of the main rod (3), one cutting ring is arranged in each clamping slot, and soil with different depths can be simultaneously and automatically sampled by the multiple cutting rings. The driving device drives the drill bit (7) to automatically rotate, so a traditional manpower driving mode is changed, the sampling efficiency is greatly improved, and the physical power of a sampling person can be saved.

Description

technical field [0001] The invention relates to the field of soil science experimental research equipment, in particular to an automatic sampler which can simultaneously use a plurality of ring cutters for sampling. Background technique [0002] The soil ring knife is often used to measure some soil properties such as soil bulk density, moisture content, density, porosity, moisture characteristic curve, etc., and plays an important role in soil science research. Common ring knives are mainly metal rings, and their volume is generally divided into 100cm 3 and 200cm 3 two kinds. At present, the common soil ring knife sampler mainly uses a hammer to drive the ring knife into the soil, and then takes the ring knife out for analysis and experiments. This soil sampling method has problems such as large disturbance of the original soil by hammering, time-consuming and laborious, large land damage area, and the ring knife is not easy to take out when deep soil sampling is perform...
