A plurality of leveling mechanisms 4 are arranged at the bottom of the fixed box body 1. The leveling mechanism 4 comprises a fixed portion 41 and a telescopic portion 42. The telescopic portion 42 can be telescoped relative to the fixed portion 41. The top end of the fixed portion 41 is arranged at the bottom of the fixed box body 1, and the bottom end of the telescopic portion 42 faces the supporting surface; the expandable box body 2 comprises a left expansion cabin 21 and a right expansion cabin 22. Openings matching the left expansion cabin 21 and the right expansion cabin 22 are arranged on both sides of the fixed box body 1. The left expansion cabin 21 and the right expansion cabin 22 are arranged in the fixed box body 1. The driving mechanism 3 is arranged at the bottom of the fixed box body 1. The driving mechanism 3 is connected to the left expansion cabin 21 and the right expansion cabin 22, respectively, and is used to drive the left expansion cabin 21 and the right expansion cabin 22 to expand or contract relative to the fixed box body 1.

[0026] In the utility model, a plurality of leveling mechanisms 4 are arranged at the bottom of the fixed box 1. When the field support surface is uneven, the telescopic portion 42 of the leveling mechanism 4 can be telescoped relative to the fixed portion 41 to adjust the height of the corresponding position of the square cabin, so that the chassis of the square cabin can maintain a horizontal state even in special terrain. At the same time, the interior of the fixed box 1 is provided with a left expansion cabin 21 and a right expansion cabin 22 that can be unfolded to both sides. After unfolding, the volume of the cabin is increased, providing a wide space for field operations. When not in use, it can be retracted into the fixed box 1, reducing the occupied space, facilitating movement, and meeting the mobility requirements of special field terrains.

[0027] In some embodiments, Figure 1 and Figure 5 As shown, the leveling mechanism 4 includes a leveling electric drive 43 and a leveling handle 44. The leveling electric drive 43 can be an electric hydraulic pump. The leveling electric drive 43 and the leveling handle 44 are arranged at the side end of the fixed part 41, and are both connected to the telescopic part 42 by transmission. The leveling electric drive 43 is used for electric leveling of the fixed box 1, and the leveling handle 44 is used for manual leveling of the fixed box 1. By connecting the leveling electric drive 43 and the leveling handle 44 to the telescopic part 42 by transmission, the fixed box 1 can be leveled electrically or directly manually, which is more convenient. The load of the leveling mechanism 4 is not less than 10,000 kg, and the maximum leveling stroke is 500 mm. In actual operation, electric leveling is mainly used, and manual fine-tuning can be achieved.

[0028] In some embodiments, Figure 2-Figure 4 As shown, the left expansion cabin 21 and the right expansion cabin 22 are pentahedral structures with an opening at one end, and the openings of the left expansion cabin 21 and the right expansion cabin 22 are opposite to each other and both face the inside of the fixed box 1. By designing the left expansion cabin 21 and the right expansion cabin 22 as pentahedral open structures, the left expansion cabin 21, the right expansion cabin 22 and the fixed box 1 form a closed whole when expanded and retracted to both sides of the fixed box 1, which is convenient for personnel to work inside the cabin without being affected by the outdoor environment.

[0029] In some embodiments, Figure 3 and Figure 4 As shown, a bottom plate 5 is provided inside the fixed box body 1, and a lifting assembly 6 is connected to the lower end of the bottom plate 5. The lifting assembly 6 can be a hydraulic cylinder. The lifting assembly 6 is used to drive the bottom plate 5 to move vertically. When the expansion cabins on both sides are retracted, the bottom plate 5 is located above the lower side plate 211 of the left expansion cabin 21 and the lower side plate 221 of the right expansion cabin 22. When the expansion cabins on both sides are unfolded, the bottom plate 5 is driven by the lifting assembly 6 to move downward to a position flush with the lower side plate 211 of the left expansion cabin 21 and the lower side plate 221 of the right expansion cabin 22, forming an enclosed space with better sealing and a smoother ground inside the cabin.

The driving mechanism 3 includes a telescopic driving member 31, a guide fixing seat 32 and a guide telescopic rod 33. The telescopic driving member 31 can be a motor. The telescopic driving member 31 and the guide fixing seat 32 are arranged at the bottom of the fixed box body 1, and the guide telescopic rod 33 is arranged on the guide fixing seat 32. The end of the guide telescopic rod 33 is correspondingly connected to the side wall of the left expansion cabin 21 or the right expansion cabin 22. The telescopic direction of the guide telescopic rod 33 is consistent with the telescopic direction of the left expansion cabin 21 or the right expansion cabin 22 connected thereto. A rack 34 is arranged on the guide telescopic rod 33, and a gear is arranged on the output shaft of the telescopic driving member 31, and the gear is meshed with the rack 34. By setting the rack 34 on the guide telescopic rod 33, the guide telescopic rod 33 is connected to the side walls of the expansion cabins on both sides. When the telescopic driving member 31 drives the expansion cabin to expand to both sides, the guide telescopic rod 33 also expands and contracts synchronously, playing a supporting and guiding role, so that the expansion and contraction process of the left expansion cabin 21 and the right expansion cabin 22 is more stable and the transmission effect is better.
