Multifunctional soil sample collecting equipment

Abstract

The invention discloses multifunctional soil sample collecting equipment. The equipment comprises a bracket, and a first sampling assembly and a second sampling assembly which are arranged on the bracket, wherein hydraulic supporting legs are mounted at four corners of the bottom end surface of the bracket; rolling wheels are mounted at the bottom ends of the four groups of hydraulic supporting legs; a horizontal cross beam is fixedly connected between the two groups of parallel hydraulic supporting legs, a screw rod is inserted between the two groups of cross beams, the screw rod is sleeved with a sliding block, the first sampling assembly is vertically mounted on the sliding block, a group of fixing plates are further welded to the outer side of the bracket, and the second sampling assembly is vertically mounted on the fixing plates. According to the multifunctional soil sample collecting equipment, two groups of samples can be sampled at the same time, the overall distance between the two groups of samples is adjusted, the multifunctional soil sample collecting equipment adapts to different sampling depths, sampling is convenient after sampling is completed, fixed-point sampling, soil depth measurement and other functional effects are achieved, the multifunctional soil sample collecting equipment adapts to ground supports with different gradients, and the diversity of the equipment is embodied.

Description

technical field [0001] The invention belongs to the technical field of soil sampling machinery, and in particular relates to a multifunctional equipment for collecting soil samples. Background technique [0002] Soil sample collection is an important link in the process of analyzing soil organic matter, nutrient content, particle size composition and other physical and chemical properties, and the quality of soil sample sampling is a prerequisite for the accuracy of experimental analysis results. In order to truly reflect the characteristics of the overall sample through some samples in the field, it is required that the samples collected in the field be representative. Therefore, it is very critical to reduce the disturbance to the original soil sample during the sampling process. Usually, the number of soil samples collected during the test is relatively large. If multiple samples can be collected at one time, the work efficiency can be significantly improved. [0003] A...

Problems solved by technology

[0003] At present, the collection of soil samples usually adopts a circular tube sampler. After the soil sample is collected by this sampler, the common way to take out the soil sample is to use a push rod to push the soil sample out of the circular tube. The process of pushing out is not only time-consuming and laborious, but also It will inevitably squeeze the soil sample, destroy the original soil, and thus artificially disturb the sample; at the same time, the existing sampler can only collect one soil sample at a time. If the number of samples is large, the workload is large, and the existing The sampler has a single function, and most of them can only realize one function
