Soil collecting device for forest ecosystem

Abstract

The invention relates to a soil collecting device for a forest ecosystem. The soil collecting device comprises a cutting ring, wherein the cutting ring is located in a sleeve arranged in a box body, the bottom part of a spiral conveying blade on a rotating shaft is connected with an arc-shaped cutter, the top part of the cutting ring is provided with a discharge port, a threaded rod rotationally connected with the top part of the cutting ring extends out of the box body, and the discharging opening is connected with a collecting tank through a material guiding pipe penetrating through the side wall of the sleeve; the collecting tank is arranged below the discharging end of the material guiding pipe, one side of the collecting tank is slidably connected with a push plate in the horizontal direction, the other side of the collecting tank is slidably connected with a baffle in the vertical direction, a weight sensor is arranged on the bottom wall of the collecting tank, a fixing plate is arranged in the box body and vertically connected with the push plate through an electric telescopic rod, and the weight sensor controls the electric telescopic rod to stretch out and draw back; and when the weight of the soil sample in the collecting tank reaches a set threshold value, the electric telescopic rod extends to push the push plate to approach the baffle in the collecting tank, a reversing moving mechanism drives the baffle to move upwards, and the sampled soil slides into a sample outlet from the material guiding plate connected with the sample outlet end of the collecting tank.

Description

technical field [0001] The invention relates to the technical field of sampling collection, in particular to a soil collection device for forest ecosystems. Background technique [0002] Forests can not only provide humans with a large amount of timber and forest sideline products, but also play an important role in maintaining the stability of the biosphere and improving the ecological environment. The forest ecosystem is the largest ecosystem. Compared with other terrestrial ecosystems, the forest ecosystem has the most complex composition, the most complete structure, the most vigorous energy conversion and material cycle, and thus the highest biological productivity and the strongest ecological effect. [0003] With the development of science and technology and people's increasing attention to the ecological environment, soil analysis is becoming more and more important. Soil analysis is the qualitative and quantitative determination of the composition and (or) physical ...

AI Technical Summary

Problems solved by technology

[0005] In the existing soil sampling device technology, when taking soil samples for the forest, it is necessary to manually dig the soil to complete the sampling, which is time-consuming and laborious. In order to ensure the effectiveness of the detection, parallel samples need to be made, and the weight of the samples should be close to the same. The existing The soil sampling device cannot divide the sample into equal parts at the time of sampling
