[0002] The study of plant root systems is a basic research in soil science, botany, agronomy, crop cultivation and many other disciplines. As a key component of plants, the root system exchanges matter and energy with the surrounding environment. It absorbs, transmits and stores water and nutrients, and has important physiological functions. Modern agricultural science pays more and more attention to the study of root systems, and the research results can be used to guide the cultivation and management of crops and improve the yield and quality of crops. Obtaining complete and clean plant roots from the soil is an especially important part of root system research. Scientific experiments require rapid and efficient cleaning and separation of large quantities of soil roots, and complete systematic research on the root system while ensuring the physiological activity of the root system.

[0003] After searching, a Chinese invention patent disclosed a water-gas driven soil root separation device with a publication number of CN102825026A, which includes a root flushing work platform, a circulating water supply system, an air supply system and a circuit control system; the root flushing work platform is the main part for completing root flushing and root extraction; the power of the circulating water supply system is provided by a water pump, which injects water into the flushing bucket and completes the function of water-saving circulation; the air supply system is provided with an air source by an air pump, and high-pressure gas is filled into the water body in the flushing bucket along the tangential direction near the bottom of the flushing bucket, and the water in the flushing bucket is driven by the airflow to form a vortex, so that the roots and soil are automatically stirred in the flushing bucket, and at the same time, the floating bubbles formed by the airflow promote the roots to float and separate from the soil; the circuit control system is used to realize the control of the opening and closing of the water pump, the air pump and the air intake solenoid valve. The present invention has a simple structure and a novel style. The flushing of the root system and the opening and closing of the equipment are controlled by the circuit control system, which is easy to operate and has a wide range of applications. The roots can be processed in batches, and the root cleaning rate is high and the loss rate is low. It not only improves work efficiency but also greatly reduces labor intensity.

[0004] The existing separation device has the following problems: soil is separated by flushing and stirring. However, during the above separation process, due to the pressure and inertia of air flow and water flow, the tiny roots in the root system are easily broken, and the root system itself is damaged, affecting the overall integrity of the root system. At the same time, the roots are directly immersed in water. When people manually pick up the roots, due to the contamination of bacteria and microorganisms on their hands, people are affected in detecting and recording the root growth environment and factors affecting root growth.

[0018] A root multi-stage separation method, characterized in that it comprises the following steps:

[0019] S1: placement of the root system; the personnel place the separation structure on the lower end surface of the inner cavity of the fixing frame, and then pull the clamping plates towards each other, so that the clamping plates on both sides are separated from each other, so that the clamping spring between the clamping plates is extended, and the root system is placed between the two fixing structures. At this time, the clamping plates are released, so that the clamping spring is contracted, so that the clamping plates are close to each other, so that the fixing belt is attached to the surface of the root system, thereby clamping and fixing the root system;

[0020] S2: Preparation before root separation; at this time, the driving structure is started, so that the second output end of the driving motor rotates, so the rotating rod rotates, thereby rotating the two worms on both sides, and further rotating the two worm wheels meshing with the two worms. At this time, since the rotating shaft at the lower end of the pulley is fixedly connected to the second worm wheel, the pulley rotates, and then through the transmission of the belt, the pulley at the front end of the protective structure rotates, so the threaded rod rotates. At this time, due to the limitation of the lifting rod, the threaded sleeve is lifted and lowered, so the lifting rod is lifted and lowered, thereby placing the separation structure on the upper end of the rotating disk, and further engaging the groove at the lower end of the placement plate with the limiting column, so that the root system and the separation structure are placed in the inner cavity of the storage structure.

[0021] S3: Preliminary separation of soil on the root surface; at this time, water is injected into the inner cavity of the storage structure, and the stirring drive structure is started, so that the output end of the drive motor rotates, so the worm rotates, so that the worm wheel meshing with the worm rotates, so the rotating disk rotates, and because the separation structure is connected with the rotating disk through the limit column, the filter frame rotates, and then the cleaning brush on the cleaning frame cleans the large pieces of soil and impurities on the root surface.

[0022] S4: fine separation of soil and the like in the gaps on the surface of the root system; then the air pump is started, so that the external air enters the microbubble nozzle through the connecting pipe under the action of the air pump, thereby forming a large number of microbubbles through the microbubble nozzle, and the microbubbles enter the inner cavity of the filter frame through the filter holes on the filter frame. At this time, due to the small diameter of the microbubbles, they can enter tiny holes and gaps, so that when the microbubbles burst, they will generate a strong impact force, thereby removing the dirt and impurities in the gaps on the surface of the root system, and the energy and active oxygen substances released when the micro-nano bubbles burst can gently remove pollutants without causing mechanical damage or chemical corrosion to the surface of the material, thereby separating the soil carried by the root system during separation into the inner cavity of the separation structure and the storage structure, and then the air pump is turned off,

[0023] S5: Removal of the roots after separation; pull the clamping plates towards each other so that the fixing belt no longer fits the roots, thereby removing the roots from the clamping structure.

[0024] S6: Separate the soil sample and other impurities in the water for screening and separation; start the driving structure to reverse the output end of the second driving motor, so that the rotating rod and the second worm gear rotate in the opposite direction, thereby reversing the second worm gear, the belt and the telescopic structure, so that the height of the lifting structure is increased through the extension of the telescopic structure, and then the separation structure is taken out from the sealing frame through the fixed frame with the cooperation of the handle. At this time, the large particles of impurities other than the soil in the soil and the root system are separated and filtered through the filter frame, so as to facilitate personnel to detect the root growth environment, the content of each component in the soil and the soil quality.

[0025] The present invention has the following beneficial effects:

[0026] 1. The present invention protects the regulating structure during use by means of a protective structure arranged on the bottom plate, and then transmits external air to the storage structure through an air pump and a connecting pipe to form microbubbles. The stirring drive structure and the rotating structure are installed and placed through the storage structure on the bottom plate during use, and then the clean water of the root system and the mixed solution of the soil and water after cleaning are stored through the sealing frame during separation. The rotation of the rotating structure is driven and adjusted by the stirring drive structure on the storage structure during use, and then the self-locking property of the stirring drive structure is enhanced by the worm gear 1 and the worm 1, and the rotating structure and the separation structure are limited when rotation is not required. The rotating structure on the storage structure is supported and placed during use, and then the separation structure follows the rotation when the rotating disk rotates through the limiting column. The impurities such as soil on the surface of the root system are cleaned and separated by the separation structure on the rotating structure during use, and then the root system is kept intact during separation, and it is convenient for personnel to detect and record the root growth environment, and at the same time, the factors affecting the root growth are sampled and detected, so as to achieve automatic operation during use, reduce the manual operation steps of personnel, improve the separation efficiency of the equipment, and reduce the work intensity.

[0027] 2. The present invention installs and places the lifting structure during use through the adjustment structure arranged on the base plate, and then adjusts the forward and reverse rotation of the telescopic structure through the belt and the pulley. The height of the threaded sleeve and the lifting structure is lifted and lowered by the forward and reverse rotation of the threaded rod through the telescopic structure on the adjustment structure. The clamping structure is installed and placed during use through the lifting structure on the adjustment structure, and then the relative height of the separation structure is adjusted by the fixed frame when the lifting rod is lifted and lowered. The root system is clamped and placed during use through the clamping structure on the lifting structure, and then the clamping area of ​​the device is increased by the clamping plate and the mounting frame, thereby enhancing the stability of the root system during cleaning. At the same time, with the cooperation of microbubbles, the breakage and damage of small roots in the root system caused by excessive water pressure when people directly flush is avoided, and the integrity of the root system when the root system is separated is improved. The rotation of the pulley is driven by the driving structure on the base plate during use, and then the lifting height of the telescopic structure and the lifting structure is adjusted and limited by the worm gear 2 and the worm gear 2 when the telescopic structure is lifted and lowered.
