Fig. 1 is a schematic structural view of some embodiments of implement attachment devices according to the present disclosure. Referring to fig. 1 and 2-5, in some embodiments, an implement attachment arrangement includes: the connecting frame 1, the first connecting component 2, the second connecting component 4, the first position adjusting component 3 and the second position adjusting component. The connecting frame 1 has a main machine mounting end 5 for connecting with the construction machine vehicle. The main machine mounting end 5 can be used for mounting and dismounting the machine tool connecting device relative to the engineering machinery vehicle.

The first linkage assembly 2 is configured to connect with one linkage end of the implement. The second linkage assembly 4 is configured to connect with the other connection end of the implement. First coupling assembling 2 with link 1 keeps away from the one end of host computer installation end 5 is connected, and is in but follow first direction translation on the link 1, and second coupling assembling 4 with link 1 keeps away from the one end of host computer installation end is rotationally connected, just the axis of rotation of second coupling assembling 4 with first direction is parallel.

In this way, the first connecting assembly 2 and the second connecting assembly 4 can be connected with various machines with different first distances through the rotation of the second connecting assembly 4 relative to the connecting frame 1. The first distance is the distance between one connection end and the other connection end of the implement. In other words, for implements with different first distances, when the implements are required to be installed on the implement connecting device, the first connecting assembly 2 can be connected with one connecting end of the implement, and the second connecting assembly 4 can be adaptively adjusted to the other connecting end of the implement through the rotation of the second connecting assembly 4 so as to be connected, so that the adaptability of the implement is effectively improved, and the installation requirements of the implements with different first distances are met.

And after the machine and the machine connecting device are installed, the first connecting assembly, the connecting frame, the second connecting assembly and the machine can integrally form a two-rod three-hinge-point structure which cannot move left and right and rotate, so that the structural strength and rigidity of the machine connecting device are ensured.

The first position adjusting member 3 is disposed on the connecting frame 1, connected to the first connecting member 2, and configured to adjust a position of the first connecting member 2 in the first direction. A second position adjusting assembly is disposed on the connecting frame 1, connected to the second connecting assembly 4, and configured to adjust a position of the second connecting assembly 4 in the first direction. The positions of the first connecting assembly 2 and the second connecting assembly 4 in the first direction can be adjusted through the first position adjusting assembly 3 and the second position adjusting assembly 4 respectively, so that the connection requirements of the machine tool connecting device and machine tools with different specifications in the first direction are met.

To ensure stability of the connection, referring to fig. 1, in some embodiments, the first connection assembly 2 comprises: two first connection assemblies 2 arranged at intervals along the first direction. The two first connection assemblies 2 are configured to be connected to the two ends of one connection end of the implement, respectively. The second connecting assembly 4 comprises: two second connecting assemblies 4 arranged at intervals along the first direction. Two second connecting assemblies 4 are configured to be connected with two ends of the other connecting end of the implement, respectively. This results in four connection points between the implement attachment means and the implement, making the connection more stable.

Correspondingly, the first position adjusting assembly 3 adjusts the position of the first connecting assembly 2 and/or the second position adjusting assembly adjusts the position of the second connecting assembly 4, so that the two first connecting assemblies 2 and/or the two second connecting assemblies 4 can be connected with various machines with different second distances. The second distance here is the center distance between the two ends of one connecting end of the implement and/or the center distance between the two ends of the other connecting end of the implement.

In other words, for the implements with different second distances, when the implements are required to be installed on the implement connecting device, the relative positions of the two first connecting assemblies 2 can be adjusted by the first position adjusting assembly 3 to achieve the adjustment of the distance between the two first connecting assemblies, and the positions of the two second connecting assemblies 4 can be adjusted by the second position adjusting assembly to achieve the adjustment of the distance between the two second connecting assemblies. Meanwhile, the relative positions of the first connecting assembly 2 and the second connecting assembly in the first direction are achieved by the first position adjusting assembly 3 and the second position adjusting assembly. Therefore, the adaptability of the machine tool is effectively improved, and the installation requirements of the machine tools with different second intervals are met.

In some embodiments, the attachment brackets may be arranged to mirror symmetrically in the left-right direction. And the positions of the two first connecting assemblies and the two second connecting assemblies on the connecting frame respectively can be adjusted through the corresponding position adjusting assemblies according to actual needs. In some machines, the center distance between two ends of one connecting end is the same, and the center distance of the other connecting end is different, and the first position adjusting assembly 3 or the second position adjusting assembly is selected to adjust correspondingly.

The beam inner rib plate 16 is fixedly connected between the inner wall surfaces of the box-shaped beam 15, and the strength and the rigidity of the box-shaped beam 15 are effectively improved. The transverse shaft middle rib plate 17 is fixedly connected between the transverse shaft rod 14 and the box type beam 15, so that the transverse shaft rod 14 and the box type beam 15 can integrally bear load, and the integral strength and rigidity of the connecting frame 1 are further improved.
