Description

Technical Field

[0001] The invention relates to the technical field of drying boxes, in particular to an intelligent soil experiment drying box. Background Art

[0002] Soil drying oven is a kind of equipment specially used for drying soil samples. It is widely used in agriculture, environmental science, geological exploration and other fields. With the deepening of scientific research and the increase of interdisciplinary research, the requirements for the processing of soil samples are getting higher and higher. For example, in the study of soil physical properties, soil moisture content determination, particle size distribution analysis, etc., soil samples need to be dried quickly and evenly. The emergence of soil drying oven is to meet this demand.

[0003] Traditional soil experiment drying boxes are unable to effectively process the soil, such as how to increase the drying area during the drying process, how to ensure the drying temperature, and the uniform distribution of the drying gas. As a result, the soil cannot be completely dried during the soil drying process, thus affecting the soil experiment results.

[0004] Therefore, it is very important that the present application proposes an intelligent soil experiment drying box to solve the defects existing in the prior art.

[0005] Patent document CN114234601B discloses a soil drying box drying rack for measuring soil moisture content. The above patent realizes self-adjustment of the wind plate to reduce the heat loss in the initial stage of startup, and after the temperature rises to the set temperature, the main adjustment rod piston is pushed up by the expanding gas, pushing the drying rack to produce an inclination facing the direct blowing surface of the circulating wind, thereby increasing the contact area between the circulating hot air and the soil and improving the efficiency of soil drying. However, the above patent cannot achieve the function of uniformly distributing the dry air.

[0006] Patent document CN104864687B discloses a soil dryer. The above patent realizes the drying of soil testing through a system of air supply equipment, ventilation ducts and independent boxes, and the hot air drying efficiency is high; the air purified by the filter device is basically pure air, ensuring the accuracy of soil testing; the independent drying box design prevents cross contamination; the use of multiple drying boxes allows multiple test samples to be dried at the same time and improves the overall testing efficiency, but the above patent cannot realize the automatic layer turning function of the soil.

[0007] Patent document CN116625771B discloses a sample processing device for soil storage and freeze-drying. The above patent realizes that a drying box, a crushing box, a screening box and a collection box are stacked and embedded in the casing, and a clamping component is used to assist the freeze-drying component, pneumatic clamps, multi-stage filters and material boxes to cooperate with each other. Therefore, it can not only constitute an integrated sample processing device for soil storage and freeze-drying, but also realize contactless automatic control and processing of soil in a closed environment, eliminating the soil processing process from being affected by the processing environment, causing soil pollution, and changes in the internal environmental structure of the soil causing deviations in the test results. However, the above patent cannot achieve the crushing of the soil and increase the drying area.

[0008] Patent document CN113843268B discloses a device and method for separating microplastics from karst cultivated soil. The above patent effectively breaks up soil aggregates to make the soil loose, but the above patent cannot achieve the heat dissipation and moisture removal functions of the drying process.

[0009] In summary, the above patents cannot achieve the functions of uniform distribution of dry air, automatic layer turning of soil, crushing of soil and increasing drying area, heat dissipation and moisture removal during the drying process, resulting in the problems of soil agglomeration, slow drying speed, incomplete drying of the bottom soil, and condensed water vapor dripping back into the soil; To this end, the present application proposes an intelligent soil experiment drying box that can realize the functions of uniform distribution of dry air, automatic layer turning of soil, crushing of soil and increasing drying area, heat dissipation and moisture removal during the drying process.
