[0031] The sampling mechanism 1 includes a sampling barrel 101, and an insertion rod 102 is fixedly connected around the bottom of the sampling barrel 101. The bottom end of the insertion rod 102 is set in a cone shape. Movable grooves 103 are opened around the surface of the sampling barrel 101. The inner cavity of the sampling barrel 101 is provided with a movable part 104 used in conjunction with the movable groove 103. The sampling barrel 101 can provide a storage function for the collected rice, and the insertion rod 102 can provide a positioning function for the sampling barrel 101 that is sleeved with rice, so as to facilitate the sampling of the root system of rice. In addition, the movable part 104 and the movable groove 103 can facilitate the removal of the collected rice seedlings from the sampling barrel 101.

[0032] The movable part 104 includes a fixing ring 1041, which is arranged in the inner cavity of the sampling tube 101. The fixing ring 1041 is fixedly connected with a connecting rod 1042 around it. One end of the connecting rod 1042 passes through the movable groove 103 and extends outward. The fixing ring 1041 can avoid contact with the rice seedlings in the sampling tube 101, so that the fixing ring 1041 contacts the soil around the roots of the rice seedlings, and then the rice seedlings are moved out of the sampling tube 101.

[0033] The driving mechanism 2 includes an electric cylinder 21, which is installed on the top of the sampling tube 101. The piston rod of the electric cylinder 21 is fixedly connected to a fixing plate 22. A lifting rod 23 is fixedly connected to the lower surface of the fixing plate 22 at a symmetrical position. The bottom end of the lifting rod 23 is fixedly connected to the top of the fixing rod 4. The driving force provided by the set electric cylinder 21 drives the fixing plate 22 to be raised and lowered, and then the fixing plate 22 drives the lifting rod 23 to raise and lower the position of the fixing rod 4, thereby providing power to the shovel head 5, so that the rice root system can be dug and collected.

[0034] The sliding assembly 3 includes a sliding sleeve 31, which is sleeved on the surface of the sampling tube 101. The outer wall of the sliding sleeve 31 is fixedly connected with a connecting block 32. The surface of the connecting block 32 is fixedly connected to the top of the fixed rod 4. Through the cooperation of the sliding sleeve 31 and the connecting block 32 in the sliding assembly 3, a limiting effect can be provided for the fixed rod 4, thereby enhancing the fixing effect of the fixed rod 4 when driving the shovel head 5 to move and the stability of the shovel head 5 in digging the rice root system.

[0035] The surface of the upper end of the sampling tube 101 is fixedly connected with a positioning plate 6, and a positioning sleeve 7 is embedded in the surface of the positioning plate 6 at a position corresponding to the lifting rod 23. The surface wall of the lifting rod 23 is slidably connected to the positioning sleeve 7. Through the cooperation of the positioning plate 6 and the positioning sleeve 7, a limiting effect can be provided for the position of the lifting rod 23.

[0036] A protective pad 8 is installed on the lower surface of the positioning plate 6 . The protective pad 8 fits against the top of the sliding sleeve 31 , thereby providing an anti-collision effect between the sliding sleeve 31 and the positioning plate 6 .

[0037] A plurality of collection boxes 9 are fixedly connected to the top of the fixing plate 22, and sticky notes are pasted on the surface of the collection boxes 9 to facilitate the placement of the collected and sampled rice roots.

[0038] A handle 10 is fixedly connected to the edge of the positioning plate 6 , and the two handles 10 are arranged in symmetrical positions, which can facilitate the staff to carry the sampling device to collect the root system of the rice seedlings.

[0039] According to the above-described rice root sampling device, the present invention also provides an operating method for the rice root sampling device, comprising the following steps:

[0040] Step 1: The sampling mechanism 1 is placed on the rice seedlings to be sampled, and the driving mechanism 2 drives the shovel head 5 on the fixed rod 4 to move downward to dig the rice seedlings;

[0041] Step 2: After the rice seedlings are dug, the sampling mechanism 1 is moved out of the soil, and the driving mechanism 2 drives the shovel head 5 to move upward again;

[0042] Step 3: Finally, the rice seedlings collected in the sampling mechanism 1 are moved out by the moving member 104 to complete the sampling operation of the rice seedlings.

[0043] When in use, the staff first picks up the sampling device through the handle 10, and puts the sampling tube 101 in the sampling mechanism 1 on the rice seedlings, which can provide a storage function for the collected rice. The inserted rod 102 can provide a positioning function for the sampling tube 101, which is convenient for collecting and sampling the root system of the rice. Then, the electric cylinder 21 in the driving mechanism 2 provides a driving force to drive the fixing plate 22 to move downward, and then the fixing plate 22 drives the lifting rod 23 to move the position of the fixing rod 4 downward, thereby providing pressure on the shovel head 5, so that the shovel head 5 moves toward the soil. The sampling barrel 101 can be moved inside the soil to dig and collect rice roots. After the rice seedlings are dug, the sampling barrel 101 is moved out of the soil. Similarly, the electric cylinder 21 is operated again to move the shovel head 5 upward, separate the shovel heads 5, and then the fixing ring 1041 is driven to move downward in the movable groove 103 through the connecting rod 1042. Therefore, it can not only avoid contact with the rice seedlings in the sampling barrel 101, but also make the fixing ring 1041 contact with the soil around the roots of the rice seedlings, and then the rice seedlings are moved out of the sampling barrel 101, thereby completing the sampling operation of the roots of the rice seedlings.
