[0022] As Figures 1 to 5 shown, the front loading hanging component of the tractor in this embodiment includes a frame body 1 and a connecting frame 2. The frame body 1 is the structural frame of the tractor. A hanging plate 3 is detachably installed at the front end of the frame body 1. The hanging plate 3 is installed on the frame body 1. A placement groove 4 is arranged at the front end of the hanging plate 3. The connecting frame 2 is located inside the placement groove 4. A shovel head body 5 is installed on the connecting frame 2. The shovel head body 5 is used to push an object, which is a kind of front loading device of the tractor. Mounting holes 6 are equally spaced from top to bottom at the front end of the hanging plate 3 on both sides of the placement groove 4. A U-shaped hoop 7 is jointly installed inside the two mounting holes 6. The connecting frame 2 is fixed to the hanging plate 3 through the U-shaped hoop 7. Limiting plates 8 are installed at both ends of the U-shaped hoop 7. Mounting plates 9 are detachably installed at the rear ends of the hanging plates 3 behind the U-shaped hoop 7. Limiting components are installed at the rear ends of the mounting plates 9. The limiting components are used to limit the limiting plates 8 on the U-shaped hoop 7, which is convenient for disassembling and installing the U-shaped hoop 7 and facilitating the quick fixing and disassembling of the connecting frame 2.

[0023] Specifically, a support plate 11 is installed at the lower end of the hanging plate 3, and the connecting frame 2 is located at the upper end of the support plate 11, facilitating the support of the connecting frame 2 and preventing the connecting frame 2 from moving downward during installation.

[0024] Furthermore, the limiting component includes a fixing plate 1001, a bidirectional screw 1002, threaded blocks 1003, a handle 1004, fixing blocks 1005, and limiting rods 1006. Both limiting plates 8 are installed through the mounting plate 9 via through holes. Fixing blocks 1005 are installed at the rear end of the mounting plate 9 outside the limiting plates 8. The rear end of the limiting plate 8 extends into the fixing block 1005. Fixing holes 12 are provided through both the fixing block 1005 and one end of the limiting plate 8. Two fixing plates 1001 are installed at the rear end of the mounting plate 9 above the two fixing blocks 1005. A bidirectional screw 1002 is rotatably installed between the two fixing plates 1001. Threaded blocks 1003 are threadedly connected to both sides of the surface of the bidirectional screw 1002. Limiting rods 1006 are installed at the opposite ends of the threaded blocks 1003. The limiting rods 1006 are located inside the fixing holes 12 on the fixing blocks 1005 and the limiting plates 8. One end of the bidirectional screw 1002 passes through one fixing plate 1001, and a handle 1004 is installed at one end of the bidirectional screw 1002. By inserting the limiting plate 8 on the U-shaped hoop 7 into the fixing block 1005, then rotating the handle 1004 to drive the bidirectional screw 1002 to rotate, the bidirectional screw 1002 drives the two threaded blocks 1003 to move towards each other, and the threaded blocks 1003 drive the limiting rods 1006 to insert into the fixing holes 12 on the fixing blocks 1005 and the limiting plates 8, realizing the fixation of the U-shaped hoop 7. Reversely rotating the handle 1004 can release the limitation on the limiting plate 8, facilitating the installation and disassembly of the U-shaped hoop 7.

[0025] Furthermore, the threaded block 1003 is in the shape of a cuboid, and the front end of the threaded block 1003 is in contact with the rear end of the mounting plate 9. The threaded block 1003 will not rotate along with the rotation of the bidirectional screw 1002, playing a role in limiting and guiding.

[0026] Furthermore, the size of the limiting rod 1006 matches that of the fixing hole 12. When the limiting rod 1006 is inserted into the fixing hole 12, the limiting plate 8 will not shake, effectively preventing the connecting frame 2 from shaking during installation.

[0027] Even further, the mounting plate 9 is installed at the rear end of the hanging plate 3 by bolts, and the mounting plate 9 can be disassembled, which is applicable to various situations where the U-shaped hoop 7 is used to fix the connecting frame 2, having a certain applicability.

[0028] The usage method of this embodiment is as follows: Place the connecting frame 2 on the upper end of the support plate 11, push the connecting frame 2 so that the connecting frame 2 is located inside the placement groove 4, then use the U-shaped hoop 7 to limit the connecting frame 2. At the same time, the limiting plate 8 on the U-shaped hoop 7 is inserted into the fixing block 1005. Then rotate the handle 1004 to drive the rotation of the bidirectional screw rod 1002. The bidirectional screw rod 1002 drives two limiting rods 1006 to insert into the fixing holes 12 on the fixing block 1005 and the limiting plate 8 through the threaded block 1003, realizing the limitation of the U-shaped hoop 7. The U-shaped hoop 7 fixes the connecting frame 2. Then connect the hydraulic component on the connecting frame 2 to the hydraulic device on the tractor, and the front loader of the tractor can be used. When disassembly is required, just rotate the handle 1004 in the reverse direction and remove the U-shaped hoop 7.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
