The connection position of the rotating arm 3.1 and the transmission shaft 3.3 is the geometric symmetry center point of the rotating arm 3.1, a plurality of lifting mechanisms 3.2 are arranged at the lower ends of the two ends of the rotating arm 3.1 respectively, the taking handle 3.7 is arranged at the lower end of each lifting mechanism 3.2, and the taking handle 3.7 is internally provided with the magnetite (not shown in the figure, wrapped by the taking handle 3.7). The lifting mechanism 3.2 drives the taking handle 3.7 to move downward to the lowest point, the magnetite in the taking handle 3.7 can attract the iron cup 2.2 and realize taking, and the rotating arm 3.1 drives the iron cup 2.2 taken by the taking handle 3.7 to rotate under the drive of the transmission arm motor 3.5.

[0033] The soil sample heating box 4 comprises a box body 4.2, which is open on the side facing the transmission arm 3 and is provided with a box door 4.1 that is movably matched to the open structure. The box door is matched to the open structure through sliding or pin shaft matching to realize the opening and closing of the open structure. The box body 4.2 is provided with an iron cup falling device 4.5. The iron cup falling device 4.5 is a blocking piece, the height of which is lower than the taking handle 3.7 of the transmission arm 3 and is higher than the lowest point of the iron cup 2.2 taken by the taking handle 3.7, so as to realize the limiting and blocking of the iron cup 2.2 taken by the transmission arm 3 in rotation.

When the magnet on the transmission arm 3 attracts the iron cup 2.2, it can overcome the attraction of the transmission belt 2 to the iron cup 2.2, so as to realize the taking and lifting of the iron cup 2.2 from the transmission belt 2 by the transmission arm 3.

[0040] Example three:

[0041] Preferably, on the basis of the embodiment one, the inside of the taking handle 3.7 is a hollow structure, and the magnet of the transmission arm 3 is arranged in the hollow structure to realize the limited movement of the magnet. The rotating arm 3.1 is made of iron.
