[0045] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0046] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0047] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in the directions shown in the accompanying drawings or in the vertical, perpendicular or gravitational directions for describing the relative positional relationship of the components.

[0048] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0049] The present utility model first provides a hanging mechanism.

[0050] In one embodiment, referring to the attached Figure 1 to the attached Figure 5 as shown, the hanging mechanism includes:

[0051] Support rod 1;

[0052] Connecting support 2, connected to the support rod 1 and located on the front side of the support rod 1, and the connecting support 2 is used to connect with the tie rod of the hanging mechanism;

[0053] A plurality of hooks 3 are respectively detachably connected to the support rod 1 through detachable connection structures, and their respective connection positions are adjustable in the axial direction of the support rod 1. The hooks 3 are located at the rear side of the support rod 1 and are used for hooking agricultural implements.

[0054] In the hooking mechanism of this embodiment, a connection support 2 for connecting with the pull rod of the suspension mechanism and a plurality of hooks 3 for hooking agricultural implements are respectively connected to the front side and the rear side of the support rod 1. In this way, the hooking mechanism can be used to connect the suspension mechanism and the agricultural implement. The connection positions of the plurality of hooks 3 on the support rod 1 can be adjusted according to the types of agricultural implements to be connected. Combined with the hooking connection method, the hooking mechanism can be adapted to connect a variety of different types and specifications of agricultural implements. Applying this hooking mechanism to a tractor can significantly improve the applicability of the tractor. For example, if the connection part of the agricultural implement to be connected is a long rod structure, the plurality of hooks 3 can adjust their respective connection positions on the support rod 1 according to the length of the long rod structure, so that the long rod structure of the agricultural implement can be hooked on the plurality of hooks 3 at the same time. Another example is that if the connection part of the agricultural implement to be connected is a plurality of pin shaft structures arranged at intervals, the plurality of hooks 3 can adjust their respective connection positions on the support rod 1 to be arranged in alignment with the plurality of pin shaft structures, so that the plurality of pin shaft structures of the agricultural implement can be respectively hooked on the plurality of hooks 3.

[0055] In actual application, the connection support 2 can be connected to the end of the pull rod of the suspension mechanism through fasteners such as pin shafts and bolts. For specific details, reference can be made to the subsequent embodiments.

[0056] In one embodiment, referring to the attached Figure 2 As shown, the detachable connection structure includes:

[0057] A first clamping plate 4;

[0058] A second clamping plate 5, the second clamping plate 5 and the first clamping plate 4 are respectively clamped on the front side and the rear side of the support rod 1 and are detachably and firmly connected to each other;

[0059] Wherein, the hook 3 is connected to the first clamping plate 4.

[0060] With such a setting, the hook 3 can be detachably connected to the support rod 1 and the connection position is adjustable in the axial direction of the support rod 1. Specifically, when the position of the hook 3 needs to be adjusted, the connection between the first clamping plate 4 and the second clamping plate 5 is disassembled, and then the hook 3 can be moved along the axial direction of the support rod 1 to adjust the position of the hook 3. After the adjustment is in place, the first clamping plate 4 and the second clamping plate 5 are firmly connected again to fix the hook 3.

[0061] To ensure the stability and reliability of the detachable connection structure of this embodiment when connected to the support rod 1, the support rod 1 can be set as a rod-shaped structure with a square cross-section. The first clamping plate 4 and the second clamping plate 5 can be respectively clamped on the front side and the rear side of the support rod 1. In this way, through the limiting effect of the support rod 1, the situation where the first clamping plate 4 and the second clamping plate 5 rotate around the axis of the support rod 1 can be avoided. Specifically, the support rod 1 can be a square tube, a square bar, or a rod-shaped structure formed by welding multiple plates.

[0062] Of course, in some other embodiments, the detachable connection structure can also be in other structural forms. For example, the detachable connection structure can include a connecting frame and a detachable fastener. The connecting frame is slidably connected to the support rod 1 along the axial direction of the support rod 1 and is provided with a first mounting hole. The support rod 1 is provided with a plurality of second mounting holes arranged at intervals along the axial direction. The connecting frame is fixed to the support rod 1 by passing the detachable fastener through the first mounting hole and any one of the plurality of second mounting holes. Among them, the hook 3 is connected to the connecting frame.

[0063] In one embodiment, referring to the attached Figure 2 As shown, the detachable connection structure includes a first fastening bolt, and the first fastening bolt tightly connects the first clamping plate 4 and the second clamping plate 5.

[0064] Specifically, one end of the first fastening bolt can be fixedly connected to the first clamping plate 4 through a nut or by welding, and the other end of the first fastening bolt can be fixedly connected to the second clamping plate 5 through a nut or by welding.

[0065] In one embodiment, the hook 3, the first clamping plate 4, and the first fastening bolt are integrally formed structures or are connected to each other by welding. With such a setting, the structural strength of the hook 3 when connected to the support rod 1 is effectively improved.

[0066] In one embodiment, referring to the attached Figure 1 and the attached Figure 2 As shown, the hook 3 includes:

[0067] A hook body 31, the opening of the hook body 31 is upward;

[0068] A mounting seat 32, fixedly connected to the root of the hook body 31 and the top of the mounting seat 32 is higher than the root of the hook body 31;

[0069] A pressing block 33, the first end is hinged to the top of the mounting seat 32, the second end extends above the opening of the hook body 31 and jointly encloses a clamping space with the hook body 31. The pressing block 33 can drive the second end to move away from or close to the hook body 31 when rotating around the first end;

[0070] The pressing plate 34 is detachably connected to the top of the mounting seat 32 and presses against the top surface of the pressing block 33 .

[0071] In actual application, the connecting part of the agricultural machinery can be hung in the clamping space surrounded by the hook body 31 and the pressure block 33. The pressure plate 34 presses the pressure block 33, so that the connecting part of the agricultural machinery can always be reliably hung in the hook 3 during operation, thereby improving the structural reliability of the hanging.

[0072] In one embodiment, referring to the attached Figure 1 and attached Figure 2 As shown, the mounting seat 32 includes two mounting plates, which are respectively arranged on both sides of the root of the hook body 31, the first end of the pressure block 33 is hinged between the two mounting plates through a first pin shaft, and the pressure plate 34 is connected between the two mounting plates through a second fastening bolt.

[0073] In actual application, when hanging the agricultural machinery, loosen the second fastening bolt, pull the pressure plate 43 to make the pressure plate 34 remove the pressure on the pressure block 33. At this time, the pressure block 33 can be rotated to avoid so that the connecting part of the agricultural machinery is hung on the hook body 31, and then the pressure block 33 is reset to press on the connecting part of the agricultural machinery. At the same time, the pressure plate 34 is pressed on the pressure block 33 again and the second fastening bolt is tightened to complete the hanging operation. When the agricultural machinery needs to be removed, loosen the second fastening bolt, pull the pressure plate 43 to make the pressure plate 34 remove the pressure on the pressure block 33. At this time, the connecting part of the agricultural machinery can be taken out, and the disassembly operation is completed.

[0074] Specifically, the mounting plate can be welded to the hook body 31, fastened with fasteners, or integrally formed.

[0075] In one embodiment, referring to the attached Figure 2 As shown, the second end of the pressing block 33 is formed with a notch arranged opposite to the opening of the hook body 31, and the notch and the hook body 31 together form a cylindrical clamping space. Such a configuration can make the clamping space better adapt to the rod connection part of the agricultural implement.

[0076] In one embodiment, referring to the attached Figure 1 As shown, the connecting support 2 is provided with a first connecting hole and a second connecting hole both arranged in the same direction as the supporting rod 1, and the second connecting hole is located on one side of the first connecting hole in the radial direction. In this way, the connecting support 2 can be connected to the pull rod of the suspension mechanism through the first connecting hole and the second connecting hole and form two connecting points arranged side by side. In this way, the connecting support 2 is prevented from rotating around one connecting point, and the connection strength and reliability are effectively improved.

[0082] In this embodiment, the tie rod 6 of the hitch mechanism can be set to be adjustable in height relative to the main body of the hitch mechanism. With this setting, in actual application, by adjusting the height of the tie rod 6, the ground clearance of the hitch mechanism together with the agricultural implements attached to the hitch mechanism can be adjusted. In this way, the applicability of the tractor is effectively further improved.

[0083] In one embodiment, referring to the attached Figure 5 As shown, the connecting support 2 is provided with a first connecting hole and a second connecting hole both arranged in the same direction as the support rod 1. The second connecting hole is located on one side of the first connecting hole in the radial direction. The end of the tie rod 6 of the hitch mechanism is fixedly provided with a spherical eye bearing 7 and a connecting block 8. The connecting block 8 is provided with a third connecting hole.
