Description

Technical Field

[0001] The invention relates to the technical field of soil sampling and monitoring, and in particular to a surface monitoring device for soil salinization control. Background Art

[0002] Surface monitoring devices for soil salinization control came into being against the backdrop of increasingly severe soil salinization problems worldwide. Soil salinization is seen as one of the major issues threatening agricultural production, food security and sustainability in arid and semi-arid areas. It can lead to a decline in soil productivity, water quality, soil biodiversity and soil erosion. In order to effectively monitor and manage soil salinity, researchers have developed a variety of surface monitoring devices that can accurately monitor soil salt content and provide decision support for agricultural managers, helping them optimize farmland and increase crop yields. At the same time, these devices also provide important data support for the comprehensive control of soil salinization and promote the sustainable management of soil resources.

[0003] After searching, the invention patent of Chinese patent number CN117871160B discloses a surface monitoring device for soil salinization control. During the sampling process, due to the reverse thrust of the soil on the equipment during the ring cutting process, the equipment cannot perform normal sampling after being thrust during sampling. It is necessary to manually apply downward pressure to offset the reaction force of the soil, which easily causes damage to the equipment. By utilizing the adsorption force between the drill bit and the soil, when the sampling mechanism is pushed upward, the drill bit pulls the slide shaft to slide downward, compresses the spring, and moves the pressure cover downward. Through the cooperation between the pressure cover and the push block, soil reaction force appears during the sampling process. When the equipment is pushed upward, the adsorption force between the drill bit and the soil is utilized to move the slide shaft downward, drive the pressure cover to push the push block, increase the friction between the block and the hole wall, offset the reaction force of the soil, better perform soil sampling, and avoid the reaction force of the soil during the sampling process, which causes damage to the device. Compared with the prior art, the invention patent with Chinese patent number CN117871160B solves the problem that during the sampling process of the prior art device, due to the reverse thrust of the soil on the equipment during the ring cutting process, the equipment cannot perform normal sampling after being thrust during sampling, and manual downward pressure needs to be applied to offset the reaction force of the soil, which easily causes damage to the equipment.

[0004] However, in actual use, it is difficult for the device to accurately obtain soil samples at a specific depth. The sampled soil is mostly mixed in various layers. It is difficult to obtain relatively accurate data when measuring the soil conductivity and salt content, and the monitoring effect is not good. Therefore, a surface monitoring device for soil salinization control is proposed. Summary of the invention
