Description

Soil screening ware for soil detection Technical Field The utility model relates to the technical field of soil screening for soil detection, in particular to a soil screening device for soil detection. Background In the fields of modern agriculture, environmental protection and soil research, soil detection is taken as a basic working link, the accuracy and efficiency of the soil detection directly influence the scientificity and effectiveness of subsequent research and production activities, however, the current mainstream soil screener still has a plurality of technical bottlenecks to be broken through in the aspects of function realization and structural design, and the increasingly high-efficiency screening requirement cannot be completely met. Firstly, traditional soil screening ware adopts static screening technical route more, will soil sample place on fixed screen cloth and realize the granule separation through artifical rocking or simple vibrator, lead to the interact power inadequately between soil granule in the screening process, a large amount of tiny granule is difficult to in time pass through the screen cloth hole, simultaneously, under the static screening condition, soil granule forms the stack layer easily on the screen cloth surface, further hinder the screening process, in practical application, the operating personnel often need the manual sample that turns many times or extension screening time just can barely reach essential separation effect, this kind of inefficiency screening mode has not only increased sample processing time by a wide margin, laboratory or pick-up station's work efficiency has been reduced, still because of artificial factor intervenes the risk that has increased sample pollution and data error, the quick processing ability of big soil sample of batch has been seriously restricted. Secondly, the dynamic screening of the soil samples is realized by the improved soil screeners through the rotatable screening cylinder and other core components, however, the improved devices are still rough on the installation structure design of the screening cylinder, the installation and disassembly processes of the screening cylinder are complicated due to the adoption of the traditional fixed structure, the improved soil screeners are usually completed by using various specialized tools in a multi-step operation mode, dust, clay and organic matters in the soil samples are extremely easy to adhere to the surface of the screen and the inner wall of the screening cylinder in an actual working environment, a deposition layer which is difficult to remove is formed after frequent use, the screening precision is influenced, the screen holes are possibly blocked, however, maintenance personnel cannot quickly disassemble the screening cylinder to thoroughly clean the inside of the improved soil screeners, only limited surface treatment is performed, the equipment is difficult to keep a good working state for a long time, and more troublesome disassembly and assembly processes are remarkably reduced when the screening cylinders with different apertures are required to be replaced for the soil samples with different particle size ranges, and especially in the scene that the soil samples with different particle sizes are required to be continuously processed, the application range and the use flexibility of the equipment are seriously influenced. In addition, in order to overcome the technical barriers of difficult disassembly and assembly of the screening cylinder, few manufacturers push out the soil screening device products adopting the quick disassembly and assembly mechanism, however, the quick connection mechanisms have serious defects of connection strength and stability while pursuing operation convenience, obvious vibration and shaking can be generated when the device runs in the actual working process of the soil screening device, the quick disassembly connection structure with simplified design is extremely easy to generate progressive loosening or sudden failure, when the connection structure is loose, gaps are generated between the screening cylinder and a host machine, fine soil particles are leaked and sample pollution are caused, abnormal noise and additional vibration are generated due to irregular collision among parts, equipment abrasion is accelerated, and more seriously, if the connection structure is completely separated in a high-speed running state, the rotating screening cylinder can be separated from equipment constraint, sample loss and equipment damage can be caused, operators can be injured, and serious potential safety hazards are formed.
