[0021] like Figures 1 to 6As shown, a grain unloading drum loading device includes a first flip assembly 1, a second flip assembly 2, a clamping assembly 3 and a column 4. The second flip assembly 2 is arranged on the first flip assembly 1, and the second flip assembly 2 drives the second flip assembly 2 to rotate in the first direction; the clamping assembly 3 is arranged on the second flip assembly 2, and the second flip drives the clamping assembly 3 to rotate in the second direction; the clamping assembly 3 clamps the grain unloading drum. The first flip assembly 1 can drive the clamping assembly 3 to rotate in the horizontal direction, and after driving the clamping assembly 3 to clamp the grain unloading drum 5, the placement angle of the grain unloading drum 5 is changed to facilitate transportation. The second flip assembly 2 can drive the clamping assembly 3 to rotate in the vertical direction, which is convenient for controlling the grain unloading drum 5 that needs to be clamped and placed at an angle or needs to be installed at an angle.

[0022] The first cylinder 11 is positioned on one side of the column 4. A control handle 15 is provided on the column 4, which is equipped with a plurality of control buttons 16. The control buttons 16 are electrically connected to the first cylinder 11, the second cylinder 21, and the third cylinder 22, respectively, and control the extension or retraction of the first, second, and third cylinders 11, 21, and 22. A sleeve 17 is provided at the bottom of the column 4, and the rotating shaft 13 is positioned within the sleeve 17. The first tilting assembly 1 comprises the first cylinder 11, a transmission rod 12, a rotating shaft 13, and a connecting rod 14. The transmission rod 12 is connected to the output end of the first cylinder 11, and the connecting rod 14 is connected to the rotating shaft 13, which is connected to the transmission rod 12. The transmission rod 12 is positioned at an angle. When the first cylinder 11 is extended, the transmission rod 12 rotates about the rotating shaft 13. The transmission rod 12 drives the rotating shaft 13 to rotate, and the connecting rod 14 connected to the rotating shaft 13 also rotates, thereby controlling the horizontal rotation of the clamping assembly 3.

[0023] The second flip assembly 2 includes a second cylinder 21 and a connecting seat 22. The second cylinder 21 is mounted on the connecting rod 14 via a fixing seat 23 and is hingedly connected to the fixing seat 23. The connecting seat 22 is connected to the output end of the second cylinder 21 via a control rod 24, which is hingedly connected to the output end of the second cylinder 21. The connecting seat 22 is hingedly connected to the connecting rod 14. When the second cylinder 21 extends, the control rod 24 drives the connecting seat 22 to rotate relative to the connecting rod 14. When the second cylinder 21 retracts, the control rod 24 drives the connecting seat 22 to rotate in the opposite direction relative to the connecting rod 14. The connecting rod 14 is provided with an upper limit rod 25 and a lower limit rod 26. The upper limit rod 25 is located above the connecting rod 14, and the lower limit rod 26 is located below the connecting rod 14. The limiting rod can prevent the grain unloading barrel 5 from colliding, and according to the length of the grain unloading barrel 5, the distance between the limiting rod and the connecting seat 22 can be adjusted to adapt to the grain unloading barrel 5 and prevent the grain unloading barrel 5 from colliding.

[0024] The clamping assembly 3 includes a third cylinder 31, a connecting member 32, and an articulated rod 33. The third cylinder is mounted in the connecting base 22, and the connecting member 32 is connected to the output end of the third cylinder 31. A first gripper 34 is connected to the connecting member 32. Both ends of the connecting member 32 are hinged to the articulated rod 33. A clamping arm 35 is hinged to both ends of the connecting base 22. Each clamping arm 35 is provided with a fixed rod 37. Each clamping arm 35 is provided with a movable groove 36, into which the articulated rod 33 is placed. One end of the articulated rod 33 is connected to the connecting member 32, and the other end is connected to the fixed rod 37. Each clamping arm 35 is provided with a second gripper 38. Each second gripper 38 is provided with a friction pad. After the third cylinder 31 extends, the connecting member 32 extends outward under the drive of the third cylinder 31, and the first gripper 34 moves outward until it contacts the grain unloading barrel 5. During the movement of the connecting member 32, the hinged rods 33 at both ends are driven to rotate around the fixed rod 37 as the center of the circle. During the rotation, the distance between the clamping arm 35 and the connecting member 32 is changed, causing the clamping arm 35 to rotate relative to the connecting seat 22, causing the second gripper 38 to separate to both ends, and then the grain unloading barrel 5 is placed between the first gripper 34 and the second gripper 38. When grasping, the third cylinder 31 contracts, and the second gripper 38 contracts inward, pushing the grain unloading barrel 5 onto the first gripper 34. By increasing the fixation of the first gripper 34, the fixation of the grain unloading barrel 5 is made more stable.

[0025] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
