[0040] Specifically, in the present embodiment, the positioning protruding wall ring 121 is a rectangular ring, and two positioning columns 124 are arranged on the outer side of each of the two opposite walls of the positioning protruding wall ring 121, and a total of four positioning columns 124 are arranged at the four corner positions of the positioning protruding wall ring 121. The battery fixing frame 32 is a rectangular cover-shaped member, and four positioning lugs 321 are arranged at the four corner positions of the opening of the battery fixing frame 32. The positioning lugs 321 and the positioning protruding wall ring 121 are one-to-one corresponding, and mounting holes are arranged on the positioning lugs 321 and the positioning protruding wall ring 121. Screws are passed through the mounting holes on the two to stably fix the entire battery assembly 3 on the bottom plate 12. The present application forms a mounting cavity 122 on the bottom plate 12, which is adapted to the shape of the battery pack 31. Then, the shockproof member 33 is sleeved outside the battery pack 31. Finally, a cover-shaped battery fixing frame 32 is used to fix the battery pack 31 with the shockproof member 33 in the mounting cavity 122 from above. This can effectively reduce the vibration of the battery pack 31, reduce the possibility of damage to the battery pack 31, avoid accidents, and reduce the shaking of the battery pack by arranging the battery pack in the middle position of the bottom plate. In some embodiments, when the battery fixing bracket is fixed in position with the bottom plate 12, a certain space is reserved.

At this time, the user can use force at the positions of the two notches 1211 to take out the battery pack 31.

[0049] Please refer to Figure 3 and Figure 4As shown in the figure, in an optional embodiment, the granary robot further comprises a motor controller assembly 5, the control board assembly 2 and the motor 41 controller assembly are arranged on both sides of the battery assembly 3. The drive assembly 4 comprises a motor 41, a speed reducer 42 and a drive wheel 43. The motor 41 is in driving connection with the drive wheel 43 through the speed reducer 42.

[0050] Specifically, the two ends of the chassis 12 are front end and rear end respectively, the battery assembly 3 is arranged at the middle position of the chassis 12, the control board assembly 2 is arranged at the front end of the chassis 12, and the motor 41 controller assembly is arranged at the rear end of the chassis 12. Among the internal spare parts of the granary robot, the weight of the battery assembly 3 is the largest, and the battery assembly 3 is arranged at the center position of the chassis 12 in the application, so that the center of gravity of the robot is processed at the center position of the granary robot, the balance of the granary robot is increased, the center of gravity of the granary robot is prevented from deviating, and then the granary robot is prevented from turning over or the depth before and after the operation is not the same. The control board assembly 2 and the motor controller assembly 5 are arranged on both sides of the battery assembly 3, so that the center of gravity of the whole chassis 12 is located at the position of the battery pack 31, the balance of the granary robot is further increased, the balanced operation and work of the robot are ensured, and the possibility of overturning is further reduced. It can be understood that the motor controller assembly 5 is used to control the start, pause and rotating speed of the motor 41, and the specific principle is not described here.

[0051] Please refer to Figure 4 As shown in the figure, the drive assembly 4 comprises a motor 41, a speed reducer 42 and a drive wheel 43, and the motor 41 is in driving connection with the drive wheel 43 through the speed reducer 42. In the embodiment, the motor 41 is arranged in the chassis 12, the speed reducer 42 is arranged below the motor 41, and the drive wheel 43 is also arranged below the chassis 12. The motor 41 is in driving connection with the speed reducer 42, the speed reducer 42 is in driving connection with the drive wheel 43, and the motor 41 operates under the control of the motor controller assembly 5. Two drive assemblies 4 are respectively arranged on the two side wings of the chassis 12, and the whole granary robot is driven to move by the drive wheels 43 on the two drive assemblies 4. Two drive assemblies 4 are arranged in the application, two motors 41 are arranged, and the double motors 41 provide power for the operation of the granary robot, which is powerful and stable in operation. The drive wheel 43 is a spiral wheel, when the spiral wheel is initially placed on the grain surface, the granary robot is slightly trapped in the granary under the action of its own gravity. After the motor 41 is started, the depth of the spiral wheel trapped in the grain increases until the granary robot enters a stable state and remains at this depth for forward movement, backward movement and turning operation.

[0052] Please refer to Figure 2As shown, in the embodiment, the interval between the two driving wheels 43 is A, and the outer diameter of the driving wheel 43 is D, and 0.8D<A<1.2D. The interval between the two driving wheels 43 is the distance between the outer sides of the two spiral wheels. If the interval between the two spiral wheels is too large, the spiral wheel will sink into the grain to a greater depth when running smoothly, and the greater the depth of the spiral wheel sinking into the grain surface, the more likely the chassis 12 will touch the grain surface. After the chassis 12 touches the grain surface, the running resistance increases, and it is also more likely to overturn. If the interval between the two spiral wheels is too small, it will make the entire grain storage machine unbalanced, and the overturning rate will greatly increase. Therefore, it is necessary to improve the interval between the driving wheels 43. After a large amount of data verification, the interval between the two spiral wheels is preferably between 0.8D and 1.2D. When the interval between the two spiral wheels is about the outer diameter of a spiral wheel, the effect is best, and at this time the stability of the grain storage robot is best.

[0053] Please refer to Figure 3 As shown, the grain storage robot also includes a camera vision sensor module 6 and a camera receiving module 7. The camera receiving module 7 is arranged on the chassis 12, and the camera receiving module 7 is arranged at the front end of the chassis 12. The camera receiving module 7 is fixed on the chassis 12 by screw fastening. The camera vision sensor module 6 is arranged inside the upper cover 11 and exposed to the outside world from the upper cover 11 to facilitate its acquisition of image information from the outside world. The camera vision sensor module 6 acquires the original image from the outside world and transmits the original image to the camera receiving module 7. After relevant image processing, it is finally sent to the client for real-time viewing by the user.

[0054] The above description is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation or direct / indirect application in other related technical fields within the technical concept of the present application is included in the patent protection scope of the present application.
