Throughout this application, unless otherwise specified, "plurality" means two or more.

[0050] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0051] See Figure 1-10 As shown, a multifunctional hydraulic folding unit according to an embodiment of the present application includes:

[0052] A main frame 1, one end of the main frame 1 is provided with a connector 2, the bottom of the other end of the main frame 1 is provided with a walking wheel 3, support beams 4 are symmetrically provided on both sides of the main frame 1, the same side ends of the two support beams 4 are rotatably connected to the main frame 1, the side walls of the two support beams 4 are respectively hinged to the main frame 1 through a folding cylinder 5, and suspension components are symmetrically provided on the two support beams 4. Two sliding round steels 6 are provided at the bottom of the main frame 1 corresponding to the two support beams 4;

[0053] There are two connecting components, each corresponding to the two sliding round steels 6. One end of the connecting component is hinged to the support beam 4, and the other end of the connecting component is slidably connected to the sliding round steel 6.

[0054] A locking assembly is fixedly connected to the main frame 1 and is used to fix the two support beams 4.

[0055] It should be understood that the support beam 4 is hinged to the main frame 1 via the folding cylinder 5. The extension and retraction of the folding cylinder 5 drives the support beam 4 to rotate around the main frame 1. When the folding cylinder 5 is extended, the support beam 4 moves closer to the main frame 1, achieving folding; when the folding cylinder 5 is retracted, the support beam 4 is expanded outward, forming a working state. The connector 2 is used to connect to external equipment (such as tractors, agricultural machinery, vehicles, etc.).

[0056] In some specific embodiments, the folding cylinder 5 is located on the side of the support beam 4 away from the connecting head 2, one end of the folding cylinder 5 is hinged to the support beam 4, and the other end of the folding cylinder 5 is hinged to the main frame 1, the folding cylinder 5 is arranged parallel to the support beam 4, the sliding round steel 6 is arranged parallel to the support beam 4, and the sliding round steel 6 is fixedly connected to the main frame 1 through a baffle assembly.

[0057] In some specific embodiments, the suspension assembly includes:

[0058] A support plate 25, the bottom of which is welded to the support beam 4;

[0059] A limiting rod 26, the bottom of which is hinged to the top of the support plate 25, the side wall of the limiting rod 26 is hinged to one end of the limiting hook 27, the top of the limiting rod 26 is hinged to the top of the fixing block 28, the side wall of the limiting rod 26 close to the fixing block 28 is welded with a placement seat 29, the placement seat 29 and the fixing block 28 are an integral structure, the side of the fixing block 28 away from the placement seat 29 is welded with a crossbeam 30, a limiting groove 31 is provided inside the fixing block 28, a limiting column 32 for connecting to the other end of the limiting hook 27 is fixedly connected to the inside of the limiting groove 31, a first connector 33 is hinged to the bottom of the fixing block 28, and a plurality of first hinge holes 34 are provided at the bottom of the fixing block 28;

[0060] There are two lifting assemblies, which are symmetrically arranged on both sides of the support plate 25. The bottoms of the two lifting assemblies are welded to the support beam 4, and the tops of the two lifting assemblies are welded to the cross beam 30.

[0061] It should be understood that the placement seat 29 and the fixing block 28 are connected by welding to form an integral structure.

[0062] The first connector 33 can be matched with the corresponding first hinge hole 34 according to actual working needs to adjust the position of the first connector 33.

[0063] In some specific embodiments, the lifting assembly includes:

[0064] A support base 35, one end of which is welded to the support beam 4;

[0065] A first support body 36 , the bottom of which is hinged to the other end of the support base 35 ;

[0066] A second support body 37, the top of which is welded to the crossbeam 30, the top of the first support body 36 is hinged to the side wall of the second support body 37, the bottom of the second support body 37 is hinged with a second connector 38, and the bottom of the second support body 37 is also provided with a plurality of second hinge holes 39;

[0067] One end of the suspension cylinder 40 is hinged to the side wall of the first support body 36 , and the other end of the suspension cylinder 40 is hinged to the side wall of the second support body 37 .

[0068] It should be understood that the second connector 38 can be adjusted according to actual working requirements by matching the corresponding second hinge hole 39. The first connector 33 and the second connector 38 are used to connect different working units.

[0069] When the operating units on the first connecting head 33 and the second connecting head 38 are in a moving state, the limit hook 27 is connected to the limit column 32, that is, the limit hook 27 is hung on the limit column 32, and then the limit hook 27 fixes the beam 30 and the fixed block 28.

[0070] When the operating units on the first connector 33 and the second connector 38 are in working condition, the limit hook 27 is separated from the limit column 32 , and the entire crossbeam 30 and the lifting assembly are driven to fall through the suspension cylinder 40 .

[0071] In some specific embodiments, the baffle assembly includes:

[0072] A first baffle 7, one end of the sliding round steel 6 passes through the first baffle 7, and one end of the sliding round steel 6 is fixedly connected to the first baffle 7, and the first baffle 7 is fixedly connected to the main frame 1;

[0073] The second baffle 8 , the other end of the sliding round steel 6 passes through the second baffle 8 , and the other end of the sliding round steel 6 is fixedly connected to the second baffle 8 , and the second baffle 8 is fixedly connected to the main frame 1 .

[0074] It should be understood that the first baffle 7 and the second baffle 8 are fixed to the main frame 1 by bolts or welding, forming a rigid support for the sliding round steel 6. The first baffle 7 and the second baffle 8 limit the axial movement range of the sliding round steel 6 by fixing the two ends of the sliding round steel 6, thereby preventing the sliding round steel 6 from falling off the main frame 1. The first baffle 7 and the second baffle 8 strengthen the connection strength between the sliding round steel 6 and the main frame 1 by fixing the sliding round steel 6, thereby preventing the sliding round steel 6 from being displaced or falling off during operation. This design ensures that the load of the connecting components (such as the diagonal rod 9 and the connecting block 10) can be reliably transferred to the main frame 1, thereby improving the stability of the overall structure. The baffle assembly reduces the friction and wear between the sliding round steel 6 and the main frame 1 by limiting the movement range of the sliding round steel 6, thereby extending the service life of the equipment.

[0075] In some specific embodiments, the connection component includes:

[0076] An oblique tie rod 9, one end of which is hinged to the support beam 4;

[0077] The connecting block 10 is slidably connected to the sliding round steel 6 , and the side wall of the connecting block 10 is hinged to the other end of the inclined rod 9 .

[0078] In some specific embodiments, two hooks 11 are provided on the side walls of the main frame 1 corresponding to the two second baffles 8, and the connecting ends of the two hooks 11 are rotatably connected to the side walls of the main frame 1. The two hooks 11 are located on the side of the second baffle 8 away from the first baffle 7, and the hanging ends of the hooks 11 are used to engage with the connecting block 10.

[0079] It should be understood that during the folding or unfolding of the support beam 4, the diagonal brace 9 swings along with the movement of the support beam 4 through the hinge point, providing tension or thrust to the support beam 4 and ensuring the stability of its motion trajectory. When the support beam 4 moves, the connecting block 10 slides along the sliding round steel 6, and at the same time, the hinged action of the diagonal brace 9 ensures that the movement of the support beam 4 is smooth and controllable. The diagonal brace 9 and the connecting block 10 are connected by hinges and sliding, providing a stable tension or thrust to the support beam 4, preventing it from shaking or deviating from the predetermined trajectory during the folding or unfolding process. The connecting assembly connects the support beam 4 to the main frame 1 as a whole through the cooperation of the diagonal brace 9 and the connecting block 10, thereby enhancing the structural strength and reliability of the equipment. When the support beam 4 is unfolded into place, the connecting block 10 can be snapped into the hanging end of the hook 11 to further fix the position of the support beam 4 and prevent it from moving accidentally.

[0080] In some specific embodiments, the locking assembly includes:

[0081] A lifting lock oil cylinder 12, wherein the mounting end of the lifting lock oil cylinder 12 is hinged to the main frame 1, and the axis of the lifting lock oil cylinder 12 coincides with the axis of the main frame 1;

[0082] The support frame 13 has an L-shaped axial cross-section. The telescopic end of the lifting lock cylinder 12 is rotatably connected to the top of the support frame 13. The bottom of the support frame 13 is provided with two fixing grooves 14, which are used to engage with the support beam 4.

[0083] The rotating shaft 15 is arranged at the bottom of the main frame 1, and the rotating shaft 15 passes through the bottom of the support frame 13, and the rotating end of the rotating shaft 15 is fixedly connected to the support frame 13, and the fixed ends at both ends of the rotating shaft 15 are respectively fixedly connected to the bottom of the two second baffles 8, and the lifting lock cylinder 12 can drive the support frame 13 to rotate around the rotating shaft 15.

[0084] In some specific embodiments, a connecting rod 16 is further provided at the top of the support frame 13, and the connecting rod 16 is located at the top of the lifting lock cylinder 12. The connecting rod 16 is fixedly connected to the support frame 13, and the main frame 1 is provided with a hanging hook 17 corresponding to the connecting rod 16. The connecting end of the hanging hook 17 is rotatably connected to the main frame 1, and the hanging end of the hanging hook 17 is used to clamp with the connecting rod 16. The hanging hook 17 is located on the side of the support frame 13 away from the connecting head 2.

[0085] It should be understood that when the support beam 4 contracts, the telescopic end of the lifting lock cylinder 12 extends, driving the entire support frame 13 to rotate clockwise, the support beam 4 is engaged with the support frame 13, and at the same time the suspension hook 17 is engaged with the connecting rod 16, further locking the support frame 13 to limit the rotation of the support frame 13.

[0086] When the support beam 4 needs to be unfolded, the hanging hook 17 is manually rotated to separate the hanging hook 17 from the connecting rod 16. At this time, the telescopic end of the lifting lock cylinder 12 contracts, driving the entire support frame 13 to rotate counterclockwise, and the support beam 4 is separated from the support frame 13. The folding cylinder 5 contracts to drive the support beam 4 to unfold.

[0087] In some specific embodiments, a retractable bracket 18 is provided at the bottom of the main frame 1 near the connector 2, and the retractable bracket 18 includes:

[0088] A telescopic plate 19, the telescopic plate 19 is fixedly connected to the main frame 1, the telescopic plate 19 is provided with a telescopic hole 20, and a side wall of the telescopic plate 19 is provided with a positioning hole 21, and the positioning hole 21 passes through the telescopic plate 19;

[0089] The support column 22 has an axial cross-section of an inverted T-shaped structure. The top of the support column 22 passes through the telescopic hole 20. The side wall of the top of the support column 22 is slidably connected to the inner wall of the telescopic hole 20. The side wall of the support column 22 is provided with a plurality of sockets 23, and the sockets 23 match the positioning holes 21. The support column 22 is fixedly connected to the main frame 1 by a pin 24 that passes through the positioning hole 21 and the sockets 23 in sequence.

[0090] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
