Separated soil organic matter detecting and sampling device

Abstract

The invention relates to the technical field of soil sampling, in particular to a separated soil organic matter detecting and sampling device which comprises a fixing frame, an inner sliding sleeve is slidably connected to the inner side of the fixing frame, and a rotary collecting bin is fixedly connected to the inner side of the inner sliding sleeve. The upper end of the rotating collecting bin is connected with a power mechanism used for driving the rotating collecting bin to rotate, and a magnetic mechanism used for adjusting downward pressure of the rotating collecting bin is arranged between the fixing frame and the rotating collecting bin. The magnetic field intensity of the first electromagnet and the second electromagnet is controlled by adjusting the circuit input of the first electromagnet and the second electromagnet, so that the first electromagnet is controlled to downwards push the permanent magnet, and damage caused by direct collision between the second electromagnet and the permanent magnet is prevented through repulsion between the permanent magnet and the second electromagnet; and meanwhile, through interaction of force between the permanent magnet and the second electromagnet, the permanent magnet pushes the second electromagnet to provide pushing force for downward rotary excavation of the rotary collecting bin.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a separation type soil organic matter detection and sampling device. Background technique [0002] Soil testing is a common environmental testing method. Soil environmental testing refers to the determination of environmental quality and its changing trend through the determination of representative values ​​of factors affecting soil environmental quality. In soil environmental testing, soil sampling is particularly important for technical content such as methods, data statistics, and quality evaluation. The current soil sampling method usually uses collection cylinders for soil sampling and collection activities. [0003] As disclosed in Publication No. CN112857872A, a separation-type soil organic matter detection and sampling device solves the problem that the sampling equipment needs human support during the sampling process to prevent the equipment from being overturned...

AI Technical Summary

Problems solved by technology

[0004] During the soil sampling process, it is more difficult to take a deep sample suddenly. In the deep soil sampling process, the existing equipment cannot be used to sample the sudden surface after excavation, or to use large equipment to dig the sampling device into the soil. The above methods are all Time-consuming and laborious, not light enough
