[0043] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0044] The utility model first provides a cutting platform transfer vehicle.

[0045] In one embodiment, referring to the attached Figure 1 To the attached Figure 3 As shown, the header transfer vehicle includes:

[0046] Frame 1;

[0047] The header bracket assembly 2 is provided on the vehicle frame 1 and is used to support and fix the header;

[0048] The front axle assembly 3 and the rear axle assembly 4 are arranged in sequence at the bottom of the frame 1 in the direction from the front end to the rear end of the frame 1. The front axle assembly 3 includes a front wheel 31 that can float up and down, and the rear axle assembly 4 includes a rear wheel 41 that can float up and down.

[0049] In the harvesting platform transfer vehicle of the present embodiment, the front axle assembly 3 includes a front wheel 31 that can float up and down, and the rear axle assembly 4 includes a rear wheel 41 that can float up and down. This arrangement effectively improves the passability of the harvesting platform transfer vehicle. When the harvesting platform transfer vehicle is traveling on an uneven road surface, both the front wheel 31 and the rear wheel 41 can float up and down to adapt to different road conditions. In this way, the driving stability of the harvesting platform transfer vehicle is ensured, and the problem of the harvesting platform falling and being damaged due to bumps is effectively avoided.

[0050] Specifically, the header support assembly 2 includes two main supports and two auxiliary supports. The two auxiliary supports are spaced apart along the front-to-back direction of the vehicle frame 1, and the two main supports are spaced apart along the front-to-back direction of the vehicle frame 1 and positioned between the two auxiliary supports. Each main support and auxiliary support includes a first connector, a second connector, a connecting rod, and a diagonal brace. The first and second connectors are fixedly connected to the vehicle frame at intervals along the left-to-right direction of the vehicle frame. The bottom end of the connecting rod is fixedly connected to the first connector via bolts, and the top end extends upward. The first end of the diagonal brace is fixedly connected to the top end of the connecting rod via bolts, and the second end is fixedly connected to the second connector via bolts. The diagonal brace is arranged to tilt downward from the first end to the second end. The main support also includes a support member fixedly connected to the second end. In actual use, the header is supported on the two main supports and two auxiliary supports. The inclined diagonal brace and support member limit and support the header, ensuring that the header is relatively stably supported on the header support assembly 2.

[0051] Specifically, the first end of the diagonal support rod can be provided with a plurality of first connecting holes at intervals along the length direction, and the top end of the connecting rod is provided with a second connecting hole. The second connecting hole and one of the plurality of first connecting holes are selectively connected by bolts to fix the first end of the diagonal support rod and the top end of the connecting rod. With such an arrangement, the inclination angle of the diagonal support rod can be adjusted by selecting and connecting different first connecting holes to adjust the placement angle of the cutting table; in addition, the first connecting member and the second connecting member are detachably fixedly connected to the frame, so that the main bracket and the auxiliary bracket can be adjusted in the front and rear directions of the frame. With such an arrangement, the cutting table transfer vehicle can be suitable for cutting tables of different cutting widths and different types.

[0052] Specifically, the cutting platform support assembly 2 may also include a reinforcing rod, which is fixedly connected to the diagonal support rods of the main support and the diagonal support rods of the auxiliary support in sequence. Such an arrangement can form the cutting platform support assembly 2 into a whole, effectively improving the structural strength and force uniformity of the cutting platform support assembly 2.

[0053] In one embodiment, referring to the attached Figure 1 To the attached Figure 3 As shown, the front axle assembly 3 also includes:

[0054] A front axle support 32 is provided at the bottom of the front end of the vehicle frame 1;

[0055] The front axle cross beam 33 is rotatably hinged to the bottom of the front axle support 32 around a first horizontal axis. The first horizontal axis extends in the front-to-back direction. Both ends of the front axle cross beam 33 extend toward the left and right sides of the vehicle frame 1 and are rotatably connected to the front wheels 31 respectively.

[0056] It can be understood that the front axle cross beam 33 is rotatably hinged to the bottom of the front axle support 32 around the first horizontal axis. Such an arrangement can enable the front wheel 31 to float up and down relative to the vehicle frame 1.

[0057] Specifically, the front wheel 31 can be configured so that the axle is detachably connected to the front axle crossbeam 33. This configuration allows the front wheel 31 to be quickly disassembled for easy maintenance.

[0058] In one embodiment, referring to the attached Figure 1 To the attached Figure 3 As shown, the front axle support 32 is rotatably connected to the bottom of the front end of the frame 1 around a vertical axis; the header transfer vehicle also includes a traction frame 5, which is connected to the front axle support 32 and extends toward the front of the frame 1.

[0059] It can be understood that in actual application, the harvester transfer vehicle is connected to the tail of the harvester through the traction frame 5, and the harvester tows the harvester transfer vehicle to move. In this embodiment, the traction frame 5 is connected to the front axle support 32 and the front axle support 32 is rotatably connected to the front end bottom of the frame 1 around the vertical axis. This arrangement allows the front wheels 31 of the harvester transfer vehicle to have the function of follow-up steering during the process of being towed, effectively avoiding the situation where the front wheels 31 are damaged by being pulled hard.

[0060] In addition, in this embodiment, the traction frame 5 is connected to the front axle support 32. Compared with the existing harvesting platform transfer vehicle in which the traction frame is connected to the front axle crossbeam, the height position of the traction frame 5 is higher. After the traction frame 5 is hung to the rear hanging part of the harvester, the traction frame 5 as a whole can be arranged roughly horizontally. During the traction process, the force in other directions is small, and it is more stable and reliable.

[0061] In one embodiment, the traction frame 5 is pivotally connected to the front axle support 32 about a second horizontal axis, which extends in the left-right direction. This arrangement allows the traction frame 5 to swing up and down relative to the front axle support 32, improving the convenience and adaptability of the traction frame 5 when attached to the rear end of the harvester.

[0062] In one embodiment, referring to the attached Figure 2 and attached Figure 3 As shown, the traction frame 5 includes two tie rods and a traction ring. The two tie rods are respectively connected to the left and right sides of the front axle support 32 and extend toward the front of the front axle support 32. The distance between the two tie rods gradually decreases from the back to the front. The traction ring is fixedly connected to the ends of the two tie rods away from the front axle support 32. This arrangement makes the traction frame 5 have good structural strength and is more solid and reliable than existing traction frames.

[0063] Specifically, a plurality of reinforcement members may be fixedly connected between the two tie rods.

[0064] In one embodiment, the front axle support 32 is provided with first floating stoppers at both ends of the two front wheels 31. The two first floating stoppers engage with the front axle crossbeam 33 to limit the vertical floating range of the front wheels 31, thereby preventing the harvesting platform transfer vehicle from overturning or tipping over due to excessive vertical floating of the front wheels 31 during operation.

[0065] Specifically, the first floating limiter may be a limit plate welded or integrally formed on the front axle support 32 .

[0066] In one embodiment, referring to the attached Figure 1 To the attached Figure 3 As shown, the rear axle assembly 4 includes:

[0067] The rear axle cross beam 42 is fixedly connected to the bottom of the vehicle frame 1 and has two ends extending toward the left and right sides of the vehicle frame 1 respectively;

[0068] Two mounting seats 43 are fixedly connected to the bottom of both ends of the rear axle crossbeam 42;

[0069] The two mounting longitudinal beams 44 are respectively hinged on the bottom of the two mounting seats 43 so as to be rotatable around a third horizontal axis. The third horizontal axis extends in the left-right direction. The two ends of each mounting longitudinal beam 44 extend toward the front and rear of the frame 1 and are respectively rotatably connected to the rear wheels 41.

[0070] As can be understood, the mounting beams 44 are pivotally hinged about the third horizontal axis to the bottom of the mounting base 43. This arrangement enables the rear wheels 41 to float up and down relative to the vehicle frame 1. Furthermore, each mounting beam 44 has two ends extending toward the front and rear of the vehicle frame 1 and rotatably connected to the rear wheels 41. This arrangement significantly improves the support strength of the rear axle assembly 4.

[0071] Specifically, the rear wheel 41 can be configured such that the axle is detachably connected to the mounting longitudinal beam 44. This configuration allows the rear wheel 41 to be quickly disassembled for easy maintenance.

[0072] In one embodiment, the mounting seat 43 is provided with a second floating stopper at each end facing the two rear wheels 41. The two second floating stoppers are respectively engaged with the mounting longitudinal beam 44. This arrangement, through the restraining action of the two second floating stoppers on the mounting longitudinal beam 44, limits the vertical floating range of the rear wheels 41, preventing the harvester transfer vehicle from overturning or tipping over due to excessive vertical floating of the rear wheels 41 during operation.

[0073] Specifically, the second floating limiter may be a limit plate welded or integrally formed on the mounting longitudinal beam 44 .

[0074] In one embodiment, the frame 1 is provided with a spare tire mounting position for a harvester between the front end and the header support assembly 2; and / or the frame 1 is provided with a spare tire mounting position for a transfer vehicle at the rear end.
