DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 To Attachment Figure 6 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0029] A loader attachment with a quick-change structure includes an attachment 1, a hanger 5 and a driver 8, wherein the attachment 1 is used to load goods, the hanger 5 is used to connect to the hanger 5 of the transfer machine, and the hanger 5 forms a detachable quick-change connection with the attachment 1. The type of attachment is not limited here, and it can be a bucket or a fork.

[0030] A hanging structure 2 is provided on the back of the attachment 1, and the hanging structure 2 includes a hooking portion 3 and a hole portion 4. Specifically, the hanging structure 2 is two plates of the same structure fixed to the back of the attachment 1, and the two plates are arranged in parallel and spaced apart. The hooking portion 3 and the hole portion 4 are arranged at both ends of the plate, and the hooking portion 3 includes a circular semi-enclosed structure 9 and a tangential portion 10 extending along its tangent direction.

[0031] The hanger 5 is provided with a shaft section 6 connected to the hooking part 3, and the shaft section 6 is connected with a first fixing plate 11, a second fixing plate 12 and a third fixing plate 13. The first fixing plate 11, the second fixing plate 12 and the third fixing plate 13 are arranged in parallel and spaced apart, and the first fixing plate 11 and the third fixing plate 13 are respectively connected to the two ends of the shaft section 6, and the second fixing plate 12 is connected to the middle part of the shaft section 6. The first fixing part 11 is provided with a first hanging point A, the second fixing plate 12 is provided with a second hanging point B, and the third fixing plate 13 is provided with a third hanging point C, and the first hanging point A, the second hanging point B and the third hanging point C form a triangular distribution. It is connected to the loader through the first hanging point A, the second hanging point B and the third hanging point C. The first fixing plate 11 and the third fixing plate 13 respectively include a first plate 14 and a second plate 15 arranged relatively parallel, and a guide sleeve 16 is fixedly connected between the first plate 14 and the second plate 15. The driver 8 is an electric telescopic rod. The driver 8 is arranged between the first fixed plate 11 and the third fixed plate 13. The two ends of the driver 8 are connected with a pin shaft 7. The driver 8 is used to drive the pin shaft 7 to extend and retract. The pin shaft 7 is slidably connected with the guide sleeve 16. The first fixed plate 11 and the third fixed plate 13 are provided with a flange 17. The pin shaft 7 is slidably connected with the flange 17 to enhance the guiding property of the pin shaft 7.
