DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1 to Figure 2 The utility model provides a technical solution: an excavator loader bucket that is easy to replace, comprising a bucket body 1, a bottom edge of the bucket body 1 is provided with shovel teeth, and a reinforcing seat 13 is provided on the top of the bucket body 1. Because the top of the bucket is connected to the excavator mechanical arm when the bucket is working, the top of the bucket body is a force point, and the provided reinforcing seat can strengthen the top strength of the bucket body;

[0023] like Figure 1 and Figure 2 As shown, the back surface of the bucket body 1 is provided with multiple first reinforcing edges 14, the top of the first reinforcing edge 14 is connected to the edge of the reinforcing seat 13, the first reinforcing edge 14 runs through the entire back of the bucket body, and at the same time, reinforcing edges 15 are provided at both side edges of the bucket body 1, the two ends of the reinforcing seat 13 are connected to the reinforcing edges 15, and second reinforcing edges 16 are provided between the reinforcing edges 15, so that the strength of the bucket body can be further enhanced to ensure that the bucket body will not crack or deform during long-term use.

[0024] like Figure 1 As shown, this solution also includes a first mounting seat 9 and a second mounting seat 10;

[0025] A detachable connecting mechanism is provided at the bottom of the first mounting seat 9, a driving arm 11 is installed at the bottom of the second mounting seat 10, and a U-shaped seat 6 with an opening facing downward is provided at the bottom of the driving arm 11 and the bottom of the detachable connecting mechanism;

[0026] A cylinder fixing seat 12 is installed in the middle of each U-shaped seat 6, and a double-headed hydraulic cylinder 17 is arranged in the cylinder fixing seat 12. The two free ends of the double-headed hydraulic cylinder 17 are coaxially connected to the telescopic shaft 5, and the telescopic shaft is movably penetrated on the side of the U-shaped seat 6. When the double-headed hydraulic cylinder 17 is extended or retracted, it can drive the telescopic shaft 5 to extend or shorten on the side of the U-shaped seat 6;

[0027] like Figure 1 As shown, connecting rings 3 are provided on both sides of each U-shaped seat 6. When the double-headed hydraulic cylinder 17 is extended, the telescopic shaft 5 is placed in the connecting ring 3. The connecting ring 3 is located at the top of the bucket body 1. Each connecting ring is fixed to the top of the bucket body 1 through the connecting seat 2, that is, the connecting ring 3 is fixed to the top of the bucket body. The specific installation method is to install the connecting seat 2 on the reinforcing seat 13, and the two connecting rings 3 on the same side are connected by a reinforcing plate 4, and the reinforcing plate 4 is connected to the reinforcing seat 13, so that the supporting strength of the connecting ring 3 can be increased.

[0028] Specifically, when the utility model is in use, the second mounting seat 10 is provided with a pin hole 18 parallel to the telescopic shaft 5, the second mounting seat 10 is rotatably connected to the bottom of the excavator arm through the pin shaft, and the first mounting seat 9 is fixedly installed at the bottom of the boom, so that the mechanical arm can move normally;

[0029] When the bucket needs to be replaced, just place the bucket on the ground, then control the double-headed hydraulic cylinder 17 to shorten, and let the double-headed hydraulic cylinder 17 drive each telescopic shaft 5 to disengage from the connecting ring 3. Of course, during installation, control the bottom of the mechanical arm to be placed between the connecting rings 3, and control the double-headed hydraulic cylinder 17 to drive the telescopic shaft 5 to be placed in the connecting ring. The operation is simple and easy to use.

[0030] Because the second mounting seat 10 is rotatably connected to the bottom of the forearm, the second mounting seat 10 can be disassembled by pulling out the pin shaft at the bottom of the forearm, but the first mounting seat 9 is fixedly connected to the bottom of the big arm. At this time, the detachable connection mechanism can reflect its value. The U-shaped seat 6 can be disassembled by the detachable connection mechanism. Figure 1 As shown, the detachable connecting mechanism includes fastening seats 8 arranged on both sides of the bottom of the first mounting seat 9, a fixed support 7 is arranged between the fastening seats 8, the fixed support 7 and the fastening seat 8 are connected by a locking member, and the bottom of the fixed support 7 extends to the outside below the fastening seat 8 and is connected to the top of the U-shaped seat 6, wherein there are at least two locking members, which are bolts or pins, which are arranged through the fixed support 7 and the fastening seat 8.
