DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-3 The utility model provides a feeding grab bucket, including a support 1 and a connecting rod 2. The connecting rod 2 is arranged on the surface of the support 1, and the upper end of the connecting rod 2 is connected to the lifting device of the grab bucket. Adjustment structures 3 are arranged on both sides of the inner wall of the support 1, and the lower end of the adjustment structure 3 is connected to a grab bucket 4. Two grab buckets 5 are buckled with each other. A cleaning structure 5 is fixedly assembled on the top surface of the inner wall of the support 1, and the cleaning structure 5 extends into the two grab buckets 5.

[0015] Some components are installed through the support 1 to ensure the use effect of the equipment. The lifting device of the equipment is connected through the connecting rod 2 to control the upward and downward displacement of the grab 4 as a whole. By adjusting the setting of the structure 3, the grab 4 can be controlled to flip up or down. The grabs 4 on both sides flip relatively, and the overall switch of the grab 4 can be controlled to close. At the same time, the grab 4 on one side can be controlled to move as needed, ensuring that the equipment has a wide range of applications and strong practicality. Through the cooperation of the grabs 4 on both sides, the materials can be grabbed and fed. When the grabs 4 on both sides are close to closing, some small pieces of materials will often be stuck between the two grabs 4. During the lifting and feeding process, materials will continue to leak. Through the action of the cleaning structure 5, the raw materials stuck between the two grabs 4 can be cleaned out to ensure that the two grabs 4 are closed together and closed tightly to prevent materials from falling out.

[0016] The adjustment structure 3 includes an articulated seat 32, which is rotatably assembled on the inner wall of the support 1. The side end of the articulated seat 32 is equipped with a first hydraulic cylinder 31. The end of the piston rod of the first hydraulic cylinder 31 is rotatably connected to a rotating rod 33. A rotating shaft 34 is fixedly provided in the middle of the outer wall of the rotating rod 33, and the rotating shaft 34 is rotatably assembled on the inner wall of the support 1.

[0017] When the adjustment structure 3 needs to be used, the first hydraulic cylinder 31 is first opened. When the piston rod is retracted, the upper end of the rotating rod 33 will be driven to swing toward the direction of the first hydraulic cylinder 31. According to the setting of the central rotating shaft 34, the lower end of the rotating rod 33 will be displaced in an arc toward the outer end and drive the grab 4 to move. At this time, the moving grab 4 is away from the grab 4 on the other side to form an open state. The two sides move at the same time to open a larger opening. Since the upper and lower ends of the rotating rod 33 move in an arc trajectory, the first hydraulic cylinder 31 at the upper end is rotatably assembled in the support 1 through the hinge seat 32 to cooperate with the arc displacement of the upper end of the rotating rod 33.

[0018] The cleaning structure 5 includes a second hydraulic cylinder 51, which is fixedly mounted on the top surface of the inner wall of the support 1. The lower end of the piston rod of the second hydraulic cylinder 51 is fixedly mounted with a vertical rod 52, and the lower end of the vertical rod 52 is fixedly mounted with a plug plate 53. The lower end of the plug plate 53 is set to a cutting edge shape, and the lower end of the plug plate 53 can be inserted between the two grab buckets 4 after closing.

[0019] When the cleaning structure 5 needs to be used, first open the second hydraulic cylinder 51 and control the piston rod to move downward. At the same time, the vertical rod 52 drives the plug plate 53 to move downward and insert it between the grab buckets 4. Continue to move downward to clean the impurities and seal the opening.

[0020] It also includes a leak-proof structure 6 , which includes two shells 61 . The two shells 61 are respectively arranged at the lower ends of the two grab buckets 4 . The opening directions of the two shells 61 are opposite to each other, and the inner walls of the two shells 61 are filled with filling cotton 62 .

[0021] When the impurities fall, they will be sealed on the outside of the grab bucket 4 by the filling cotton 62. When the material is discharged, they will enter the feeding port together with other raw materials.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
