Description

Technical Field

[0001] This utility model relates to the field of rhizosphere soil collection technology, and in particular to a device for collecting plant rhizosphere soil samples. Background Technology

[0002] The rhizosphere is a dynamic interface between the root system and the soil. It contains rich microbial communities, root exudates, and nutrient exchange information, which is of great significance for studying plant physiology and ecology, soil microenvironment regulation, and high-efficiency crop cultivation. Strictly speaking, the rhizosphere soil is the part of the soil affected by root exudates or dead roots. The range that root exudates or dead roots can affect is relatively limited, usually within a 2-5 mm radius around the root system.

[0003] The prior art patent with publication number CN210071365U discloses a plant rhizosphere soil collection device. The fixed clamp head has a fixed brush at the upper end, a sliding groove in the middle of the fixed clamp head, and a rotating shaft at the lower part of the fixed clamp head. The movable clamp head has a movable brush at the upper end, a sliding strip in the middle of the movable clamp head that cooperates with the sliding groove, a rack machined at the lower part of the movable clamp head, and a semi-circular gear at the upper part of the movable clamp handle. A rotating shaft hole is machined at the center of the semi-circular gear, and the semi-circular gear meshes with the rack.

[0004] In the aforementioned device, the rhizosphere soil is brushed off by moving and fixed brushes against the plant roots. However, this method of collecting rhizosphere soil makes it easy for the soil to get into the gaps between the brush bristles and stick to the brush, making it difficult to remove and thus resulting in even less rhizosphere soil being collected.

[0005] To address this issue, a plant rhizosphere soil sampling device is proposed. Utility Model Content

[0028] In this device, the protective shell 2 is used to protect the internal vibration component. The upper fixed plate 1 and the lower fixed plate 5 are connected by the support column 8. The soil screening mechanism is used to screen the soil of the plant roots. When in use, the plant roots with soil are put into the soil screening mechanism. The vibration component drives several first connecting rods 3 to move up and down at the same time. The first connecting rods 3 drive the first mounting plate 4 to move up and down. The soil screening mechanism set on the first mounting plate 4 will also shake up and down quickly, thereby achieving the effect of soil screening. The screened soil falls into the collection box 7 through the funnel 6.

[0029] The scheme is further optimized. The soil screening mechanism includes a screen frame 10, a top cover 11 on the screen frame 10, a third through hole on the first mounting plate 4, the screen frame 10 is located in the third through hole, and the screen frame 10 and the top cover 11 are detachably connected to the first mounting plate 4.

[0030] Place the plant roots with soil into the sieve frame 10, then cover it with the top cover 11, and install the sieve frame 10 and the top cover 11 on the first mounting plate 4. When the sieve frame 10 shakes up and down, the plant roots with soil will shake up and down inside the sieve frame 10, which can separate the soil from the plant roots. The sieve frame 10 has several holes, so that the soil can fall out. After sieving, the sieve frame 10 and the top cover 11 can be completely removed, and the soil inside can be thoroughly cleaned. This way, more root soil can be collected.

[0032] The screen frame 10 and the top cover 11 are both mounted on the stud 12 and locked with the nut 13. To disassemble, loosen the nut 13 and remove the screen frame 10 and the top cover 11.

[0033] The scheme is further optimized. The vibration mechanism includes a motor 14. A second mounting plate 15 is fixedly connected to the top of the first connecting rod 3. The second mounting plate 15 is located inside the protective shell 2. The motor 14 is fixedly connected to the second mounting plate 15. A rotating plate 16 is fixedly connected to the output shaft of the motor 14. A second connecting rod 17 is rotatably connected to the rotating plate 16. A connecting plate 18 is fixedly connected to the second mounting plate 15. The end of the second connecting rod 17 away from the rotating plate 16 is rotatably connected to the connecting plate 18.

[0034] Motor 14 drives rotating plate 16 to rotate, rotating plate 16 drives second connecting rod 17 to move, second connecting rod 17 drives connecting plate 18 and second mounting plate 15 to move up and down, thereby realizing the up and down swaying of screen frame 10.

[0035] The scheme is further optimized. A fixed shaft 19 is fixedly connected to the rotating plate 16. The fixed shaft 19 is eccentrically set. The second connecting rod 17 has a first connecting hole at both ends. The fixed shaft 19 passes through one of the first connecting holes and is rotatably connected to the first connecting hole. A second connecting hole is opened on the connecting plate 18. A rotating shaft 20 passes through the second connecting hole and the first connecting hole. The rotating shaft 20 is rotatably set in the first connecting hole and the second connecting hole.

[0036] The eccentric setting of the fixed shaft 19 allows the second connecting rod 17 to swing up and down. The second connecting rod 17 and the rotating plate 16 are rotatably connected through the fixed shaft 19, and the second connecting rod 17 and the connecting plate 18 are rotatably connected through the rotating shaft 20.

[0037] In a further optimized design, a first stop 21 is fixedly connected to the fixed shaft 19, a second connecting rod 17 is located between the first stop 21 and the rotating plate 16, and a second stop 22 is fixedly connected to both ends of the rotating shaft 20.

[0038] The first stop 21 prevents the second connecting rod 17 from threshing and fixing the shaft 19, and the second stop 22 prevents the second connecting rod 17 and the connecting plate 18 from separating.

[0039] The design is further optimized by providing several fourth through holes on the protective shell 2. A guide tube 23 is fixedly connected inside the fourth through hole, and the first connecting rod 3 passes through the guide tube 23 and slides inside the guide tube 23.

[0040] The first connecting rod 3 moves up and down inside the guide tube 23, and the guide tube 23 makes the movement of the first connecting rod 3 more stable.

[0041] The device is used as follows: Open the top cover 11, place the plant roots with soil inside the sieve frame 10, then install the sieve frame 10 and the top cover 11 onto the stud 12, and then lock them with the nut 13. Start the motor 14, which drives the rotating plate 16 to rotate. The rotating plate 16 drives the second connecting rod 17 to move, and the second connecting rod 17 drives the connecting plate 18 and the second mounting plate 15 to move up and down, thereby making the sieve frame 10 swing up and down. When the sieve frame 10 swings up and down, the plant roots with soil will swing up and down inside the sieve frame 10, which can separate the soil from the plant roots. The sieve frame 10 has several holes, and the soil can fall out. After screening, the sieve frame 10 and the top cover 11 can be completely removed, and the soil inside can be thoroughly cleaned, so that more root zone soil can be collected.
