[0023] like Figures 1 to 6The figure shows a grain leveling robot, including a fuselage and a drive assembly arranged around the fuselage. The drive assembly is provided with an electric motor 1 and a transmission box 2. The transmission box 2 is used to drive a driving wheel 16. The fuselage includes an upper shell 3 and a lower shell 4. The upper shell 3 and the lower shell 4 are spliced ​​up and down to form the shell of the fuselage. The lower shell 4 is provided with a support portion 5 at the position where the electric motor 1 is located. The lower side of the support portion 5 is provided with a socket hole 6. The support portion 5 is provided with a through hole 7. The socket hole 6 is connected to the through hole 7. The electric motor 1 and the transmission box 2 are connected up and down to form a first assembly. The first assembly is connected to the electric motor 1 is provided with a first sleeve portion 8 at the lower end, which is sleeved with the sleeve hole 6 from bottom to top, and the upper end surface of the first sleeve portion 8 cooperates with the lower end surface of the support portion 5 to axially limit the first component. A connecting hole 9 for connecting a first fastener is provided between the upper end surface of the first sleeve portion 8 and the support portion 5. When the first sleeve portion 8 is sleeved with the sleeve hole 6 from bottom to top, the electric motor 1 is inserted into the housing of the fuselage through the through hole 7. A first sealing ring 10 is provided between the first sleeve portion 8 and the sleeve hole 6 and / or between the upper end surface of the first sleeve portion 8 and the lower end surface of the support portion 5.

[0024] like Figure 5 、 6 As shown, the lower section of the connecting hole 9 is provided on the first sleeve portion 8 and is provided with a thread, and four connecting holes are provided around the circumference of the electric motor 1. Figure 1 、 2 As shown, the upper section of the connecting hole 9 is provided on the supporting portion 5 , and the upper section of the connecting hole 9 is provided for a first fastener to pass through and be threadedly connected with the lower section of the connecting hole 9 . The first fastener is, for example, a bolt.

[0025] The first sleeve portion 8 may be the lower end cover of the electric motor 1 , or the upper end of the transmission case 2 , or may be formed by splicing the lower end cover of the electric motor 1 and the upper end of the transmission case 2 together.

[0026] In some embodiments, as Figure 2 、 5 As shown, a guide structure is provided between the first sleeve portion 8 and the sleeve hole 6 , and the guide structure is used to locate the position of the drive assembly relative to the fuselage.

[0027] Furthermore, the first sleeve portion 8 and the sleeve hole 6 are both configured to be square, and the sleeve fit of the squares constitutes a guide structure.
