A connecting pipe 6 is provided at the upper end of the panel 1 and close to the inner side of the cavity. The two ends of the connecting pipe 6 are respectively fixedly connected to the tiger head plates 5. The connecting pipe 6 is a high-strength square pipe with a size of 60x60x10mm. Two swing arm oil cylinder fixing ears 7 are provided on the connecting pipe 6. The two swing arm oil cylinder fixing ears 7 are arranged in the middle position of the connecting pipe 6. Part of the swing arm oil cylinder fixing ears 7 extends forward and is arranged in the clearance groove provided on the panel 1. An articulated plate 8 is welded between the two tiger head plates 5 and below the connecting pipe 6.

[0029] At the top of the upper end of the tiger head plate 5, a lifting hole 9 is provided. The tiger head plate 5 is assembled and connected to the tail plate through the lifting hole 9 for the lifting of the overall hinge device. On the end face of the tiger head plate 5 away from the panel 1, a first bending edge 10 is provided along its height direction. A mudguard 11 is provided outside the first bending edge 10. A first mounting hole 17 is provided outside the first bending edge 10. The mudguard 11 is assembled on the first mounting hole 17 at an adjustable angle. A sleeve 18 is welded and assembled on the end face of the tiger head plate 5 opposite to the first bending edge 10. The sleeve is used to protect the pin, extend its service life, and avoid premature fatigue fracture.

[0030] Furthermore, a second bending edge 12 is provided at the bottom of the tiger head plate 5 along its length direction. A second mounting hole 13 and a positioning hole 19 are provided on the second bending edge 12. Both the second mounting hole 13 and the positioning hole 19 are waist-shaped holes in the left-right direction. Four positioning holes 19 are arranged around the second mounting hole 13 and are connected to the axle through U-bolts, which is convenient for installation with the axle and adapts to the deviation position. The second mounting hole 13 is arranged in the middle to lock the axle, which is convenient for the axle and the hinge seat to move during the forward and backward pushing of the mini loader, thus solving the problems of the mini loader such as small space, easy deformation of the tiger head, poor strength, and inconvenient high-altitude lifting.

[0031] Furthermore, there are two articulated plates 8, which are respectively arranged above and below the through groove 3. The part of the articulated plate 8 extending forward into the cavity is U-shaped. The strengthening edge 14 provided on the articulated plate 8 is welded to the first bending edge 10. The part extending into the cavity and the strengthening edge 14 are used to strengthen the assembly strength between the articulated plate 8 and the tiger head plate 5. The part of the articulated plate 8 extending backward out of the cavity is triangular. And the two articulated plates 8 are coaxially provided with an articulated hole 15 at the triangular part. A steering oil cylinder fixing ear 16 is provided at the position of the tiger head plate 5 inside the cavity and close to the panel 1. The stroke of the steering oil cylinder is 150mm, achieving the goal of a large steering angle of 55 degrees for the mini loader and solving the problem that the steering angle generally does not exceed 30 degrees in the current market.

[0032] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
