Portable soil sampler

Abstract

The invention provides a portable soil sampler, and relates to the technical field of soil collection. A mounting sleeve is arranged at the top of the cutting ring drill bit, and a mounting cover is arranged at the top of the connecting sleeve; clamping bases are arranged on the two sides of the outer circumferential face of the connecting sleeve and the two sides of the outer circumferential face of the mounting cover, and inserting rods are arranged on the clamping bases. Through the limiting effect of the inserting rod, the cutting ring drill bit and the connecting sleeve can be rapidly and stably connected, the connecting mode of the cutting ring drill bit and the connecting sleeve is simple, the assembling efficiency is higher, the inner cutting ring rotates in the cutting ring drill bit, a soil sample in the inner cutting ring is continuously pushed through the push plate and slides outwards, and the soil sample is prevented from falling off. The automatic soil sample taking-out process is achieved, and the problems that a drill bit drilling tool is generally connected with a scale rod in a threaded mode, connecting threads are prone to loosening, the assembling stability is affected, meanwhile, the drill bit drilling tool is single in structure, a soil collection sample is prone to falling off, and the soil sample often needs to be manually taken out of the drill bit drilling tool, and the working efficiency is high are solved. And time and labor are wasted in the taking-out process.

Description

technical field [0001] The invention relates to the technical field of soil collection, in particular to a convenient soil sampler. Background technique [0002] The soil sampler can truly meet the requirements of full-layer, equal and convenient soil sampling, and solve the difficult problem of accurately collecting soil samples for soil testing, formula fertilization, soil monitoring and other soil and fertilizer work. Easily, quickly and accurately collect soil samples with maximum control over sampling errors. [0003] However, as far as the current traditional soil sampler is concerned, the drill bit is usually connected to the scale rod by means of threads. Since the drill bit is required to be rotated during use, the connecting thread is easily loosened, which affects its assembly stability. Due to the single structure, the soil samples are easy to fall off, which will reduce the integrity of the soil samples, and the soil samples often need to be manually removed fr...

[0003] However, as far as the current traditional soil sampler is concerned, the drill bit is usually connected to the scale rod by thread. Since the drill bit needs to be rotated during use, the connecting thread is easy to loosen, which affects its assembly stability. At the same time, the drill bit The structure is single, and the soil sample is easy to fall off, which will reduce the integrity of the soil sample, and the soil sample often needs to be manually removed from the drill bit, and the removal process is time-consuming and laborious
