The first drive mechanism drives the first hook arm group to move, and the second drive mechanism drives the second hook arm group to move to hook or release the bag.

[0004] In one or more embodiments, the first hook arm and the second hook arm are oriented in opposite directions. Both the first hook arm and the second hook arm are provided with an integral curved portion and a free end. The free ends of the first hook arm and the second hook arm are close together to hook the material bag or far apart to release the material bag.

[0005] In one or more embodiments, a plurality of first hook arm assemblies are connected together by a first connecting rod, wherein the first connecting rod is axially connected to the first hook arm assemblies.

[0006] In one or more embodiments, a first drive arm is provided between the first drive mechanism and the first link, and the first drive arm is axially connected to both the first drive mechanism and the first link.

[0008] In one or more embodiments, a second drive arm is provided between the second drive mechanism and the second link, and the second drive arm is axially connected to the second drive mechanism and the second link respectively.

[0009] In one or more embodiments, the frame is provided with a lower end face, the first drive mechanism drives the first hook arm of the first hook arm assembly to extend downwards out of the lower end face or retract into the frame, and the second drive mechanism drives the second hook arm of the second hook arm assembly to extend downwards out of the lower end face or retract into the frame.

[0010] The beneficial effects of this utility model are as follows: by setting a first driving mechanism to drive the first hook arm group to rotate and setting a second driving mechanism to drive the second hook arm group to rotate, the material bag is picked up and put down. The first hook arm group is equipped with multiple first hook arms and the second hook arm group is equipped with multiple second hook arms, which realizes multi-point gripping, improves the stability of gripping, and can also grip multiple material bags, realizing the simultaneous gripping of multiple material bags. The structure is practical, easy to use, saves time and effort, and reduces the labor intensity of workers. Attached Figure Description
