Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soil collection devices, in particular to a soil determination and collection device. Background Technique
[0002] Soil hydrographic constants indicate the effective degree of soil moisture for plants, the water-holding capacity of the soil, and the characteristic values of soil moisture fluidity, which are called soil hydrographic characteristics (constants), also known as soil agro-hydrographic characteristics. It includes saturated water-holding capacity, capillary water-holding capacity, field water-holding capacity, wilting humidity, maximum hygroscopicity of the soil, etc. Soil agro-hydrographic characteristics are the criteria for measuring the supply and availability of soil moisture to crops and an important basis for determining a reasonable irrigation plan. The characteristic values that reflect the physical properties of the soil and determine the soil moisture, air, and temperature conditions are called soil agro-physical characteristics. It includes soil bulk density, specific gravity, porosity, etc. Soil agro-physical characteristics have an impact on both soil fertility and agricultural labor productivity. Soil agro-hydrographic and physical characteristics need to be measured once every 5 to 10 years. If the soil structure and properties change significantly due to reasons such as farmland capital construction, it should be measured in a timely manner.
[0003] Automatic observation data products such as soil gravimetric water content, soil relative humidity, and soil water storage all require the measurement of soil bulk density and field water-holding capacity. Generally, the currently used measurement and installation tool is a 100-ml core cutter for measuring soil bulk density and field water-holding capacity. It has obvious defects in soil constant measurement, especially in the measurement of bulk density and water-holding capacity, especially for the calibration and comparative observation of frequency domain reflectometry automatic soil moisture sensors used by meteorological departments and the measurement of soil constants to produce various soil humidity products. In order to ensure that the sampled soil can fill the core cutter, that is, the soil at the upper part of the core cutter needs to be at least higher than the upper edge surface of the core cutter. In the actual operation process, the cylindrical core cutter bayonet at the lower end of the handle must be pushed to slightly lower than the trimmed soil horizontal plane. Therefore, it is inevitable to cause a certain degree of vertical extrusion to the sampled soil, resulting in an increase in the error of the measured value. Obviously, the soil bulk density is larger than the actual situation.
[0004] Therefore, it is necessary to design a soil determination and collection device that can real-time observe the thickness of the sampled soil during soil collection, so as to avoid vertical extrusion of the sampled soil and thus affect the test results. Content of the Utility Model
[0005] In view of the above problems in the prior art, the present application proposes a soil determination and collection device that can real-time observe the thickness of the sampled soil during soil collection, so as to avoid vertical extrusion of the sampled soil and thus affect the test results.
[0006] The utility model provides a soil measurement and collection device, which comprises a knife ring sleeve, a knife ring pusher, a connecting rod and a sampling knife ring, wherein the knife ring pusher is installed on the upper part of the knife ring sleeve, and the connecting rod is installed on the upper part of the knife ring pusher. An observation window is provided on the side wall of the knife ring sleeve, and an annular abutment step is provided on the inner side wall of the lower end of the knife ring sleeve. The upper end of the sampling knife ring can be clamped on the lower end of the knife ring sleeve, and the upper end of the sampling knife ring can abut against the annular abutment step, and the thickness of the soil sampled by the sampling knife ring can be observed in real time through the observation window.
[0007] As a further improvement of the above technical solution:
