It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0040] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] Figure 1-3 The ab direction in is the first direction. Figure 1 and Figure 3 The cd direction in is the second direction.

[0042] The utility model provides a regulating device. Figure 1-4 As shown, the adjusting device includes an adjusting frame 1 and a locking structure, wherein the adjusting frame 1 is arranged on the bridge device; the cutting platform body 100 and the bridge device are respectively located on both sides of the adjusting frame 1; the adjusting frame 1 includes a rotating guide portion 11, and the cutting platform body 100 abuts against the rotating guide portion 11, and the rotating guide portion 11 can guide the cutting platform body 100 to rotate around a fixed axis; the locking structure can lock the relative position of the adjusting frame 1 and the cutting platform body 100.

[0043] like Figure 1-4 As shown, when the ground angle of the header body 100 is to be adjusted, the relative position of the header body 100 and the adjustment frame 1 is first unlocked by the locking structure, and then the header body 100 is adjusted to rotate around the fixed axis under the guidance of the rotation guide 11. When the header body 100 rotates a certain angle so that the ground angle of the header body 100 is the expected ground angle, the relative position of the header body 100 and the adjustment frame 1 is locked by the locking structure to complete the adjustment of the ground angle of the header body 100 to the expected ground angle. Compared with the prior art, the structure of the adjustment device is effectively simplified on the basis of ensuring the adjustment effect; secondly, the operation steps for adjusting the ground angle of the header body 100 are simple, which effectively improves the efficiency of adjusting the ground angle of the header body 100.

[0044] The specific structures of the header body 100 and the bridge device are both prior art and will not be described in detail herein. The ground angle refers to the angle between a fixed surface on the header body 100 and the ground.

[0045] Among them, Figure 1-4 As shown, the rotation guide 11 is provided with an arc groove 111, and the cutting platform body 100 includes a bottom beam circular tube 110, and the arc groove 111 penetrates the rotation guide 11 along the length direction of the bottom beam circular tube 110, and the bottom beam circular tube 110 abuts against the inner wall of the arc groove 111. The inner wall of the arc groove 111 is arc-shaped, and the bottom beam circular tube 110 is guided to rotate around the fixed axis by the arc-shaped inner wall, so that the cutting platform body 100 rotates around the fixed axis synchronously, so as to adjust the ground angle of the cutting platform body 100 to the expected ground angle. It can be understood that the arc groove 111 is provided on the side of the rotation guide 11 close to the cutting platform body 100.

[0046] Preferably, in this embodiment, the fixed axis, the central axis of the inner wall of the arc groove 111 and the central axis of the bottom beam tube 110 are collinear. The rotation angle of the bottom beam tube 110 can be maximized on the basis of reducing the space occupied by the arc groove 111, thereby effectively increasing the rotation angle of the header body 100 and improving the working performance of the header body 100.

[0047] Among them, Figure 1-5 As shown, the locking structure includes a locking member 2, a first through hole 131 and a plurality of second through holes; one of the adjustment frame 1 and the header body 100 is provided with the first through hole 131, and the other is provided with a plurality of second through holes, and the locking member 2 passes through the first through hole 131 and one of the second through holes to lock the relative position of the adjustment frame 1 and the header body 100. In this way, the relative position of the adjustment frame 1 and the header body 100 can be locked by the locking structure after adjusting the angle of the header body 100 to the ground.

[0048] Alternatively, if Figure 2-5 As shown, there are multiple first through holes 131, and the locking member 2 passes through one of the first through holes 131 and one of the second through holes to lock the relative position of the adjustment frame 1 and the header body 100. This arrangement can improve the convenience of locking the relative position of the adjustment frame 1 and the header body 100, and can reduce the difficulty of positioning and processing multiple second through holes.

[0049] It is understandable that when the number of the first through hole 131 is one, the plurality of second through holes need to be arranged to be spaced and distributed on the same circumference around the fixed axis, so as to ensure that the locking member 2 can pass through one of the second through holes after passing through the first through hole 131 to lock the relative position of the adjustment frame 1 and the header body 100 .

[0050] In this embodiment, the exemplary locking structure includes a plurality of first through holes 131 and a plurality of second through holes. Figure 5 As shown, the locking member 2 includes a bolt 21 and a nut 22, and the bolt 21 passes through a first through hole 131 and a second through hole and is threadedly connected to the nut 22. This is to achieve locking the relative position of the adjustment frame 1 and the header body 100. In other embodiments, the locking member 2 may also adopt a pin structure, etc., which can lock the relative position of the adjustment frame 1 and the header body 100.

[0051] Among them, Figure 1-4 and Figure 6As shown, the adjustment frame 1 further includes an upper crossbeam 12, and the upper crossbeam 12 and the rotation guide 11 are spaced apart at both ends of the adjustment frame 1 along the first direction; the header body 100 further includes a top beam tube 120; the upper crossbeam 12 is formed with an avoidance groove 121, and the avoidance groove 121 penetrates the upper crossbeam 12 along the length direction of the top beam tube 120, the opening of the avoidance groove 121 faces the top beam tube 120, and the inner wall of the avoidance groove 121 is spaced apart from the top beam tube 120. This can effectively avoid the interference of the adjustment frame 1 with the top beam tube 120, ensure that the header body 100 can effectively rotate around the fixed axis, and thus effectively adjust the angle of the header body 100 to the ground.

[0052] Specifically, the upper crossbeam 12 includes two sub-crossbeams distributed at an angle, and an avoidance groove 121 is formed between the two sub-crossbeams. In this embodiment, two sub-crossbeams are exemplarily arranged to be vertically distributed and form the avoidance groove 121. The formed avoidance groove 121 is a right-angle avoidance groove.

[0053] Among them, Figure 2-5 As shown, the adjustment frame 1 also includes two connecting parts 13, one of which is distributed along the second direction on one side of the rotating guide part 11 and the upper cross beam 12, and the other connecting part 13 is distributed along the second direction on the other side of the rotating guide part 11 and the upper cross beam 12, and the two ends of the connecting part 13 are respectively connected to the rotating guide part 11 and the upper cross beam 12; the locking structure is located at the connecting part 13; the first direction and the second direction are perpendicular. So that the relative position of the adjustment frame 1 and the header body 100 can be effectively locked by the locking structure.

[0054] It is understandable that if Figure 1 and Figure 3 As shown, the second direction, the length direction of the bottom beam circular tube 110 and the length direction of the top beam tube 120 are all parallel.

[0055] Specifically, there are multiple locking structures, a portion of which is located at one connection portion 13, and the remaining portion is distributed at another connection portion 13. This can improve the reliability of locking the relative position of the adjustment frame 1 and the header body 100, and can improve the structural strength of the adjustment frame 1 and the header body 100 after they are connected into an integral structure. In this embodiment, two locking structures are distributed on each connection portion 13 by way of example.

[0056] Specifically, Figure 1 and Figure 3 As shown, the rotating guide part 11, the upper crossbeam 12 and the two connecting parts 13 are surrounded to form a communication channel 14; the header body 100 is provided with a feeding port 130, and the communication channel 14 is connected to the feeding port 130, and the communication channel 14 is used to communicate with the feeding port of the bridge device. In this way, the crops can be transported from the feeding port 130 to the feeding port.

[0057] Alternatively, if Figure 2-5 As shown, the adjustment frame 1 further includes a support portion 15, the two ends of the support portion 15 are respectively connected to the rotation guide portion 11 and the upper cross beam 12, and the support portion 15 is distributed between the two connecting portions 13. The structural strength of the adjustment frame 1 can be improved, and the reliability of the adjustment frame 1 supporting the header body 100 can be improved. It can be understood that the support portion 15 is distributed in the communication channel 14.

[0058] Further optionally, there are multiple support portions 15, and the multiple support portions 15 are spaced apart along the second direction and are all located between the two connecting portions 13. This can further improve the structural strength of the adjustment frame 1 and the reliability of the adjustment frame 1 supporting the header body 100. In order to ensure the efficiency and effect of the material being transported from the connecting channel 14 to the feed port, it is preferred that a portion of the multiple support portions 15 are spaced apart near one of the connecting portions 13, and the remaining portion is spaced apart near another connecting portion 13. In this embodiment, Figure 2-5 As shown, the exemplary number of supporting portions 15 is two, one supporting portion 15 is close to one connecting portion 13 and is spaced apart from the connecting portion 13 along the second direction, and the other supporting portion 15 is close to the other connecting portion 13 and is spaced apart from the connecting portion 13 along the second direction.

[0059] Among them, Figure 1-5 As shown, the connection portion 13 is also provided with a locking structure 3, which is used to connect with the bridge device and to lock the relative position of the connection portion 13 and the bridge device. This arrangement is used to connect the adjustment frame 1 to the bridge device. The specific structure of the locking structure 3 belongs to the prior art and will not be repeated here.

[0060] Among them, Figure 2-5 and Figure 7 As shown, the connecting portion 13 is further provided with a mounting hole 132, and the mounting hole 132 is used to mount the universal joint bracket 200. Specifically, the header device includes a header body 100, a universal joint bracket 200 and a universal joint 300. The universal joint 300 is connected to the universal joint bracket 200. Such a configuration is provided to achieve the limitation of the relative position of the universal joint 300 and the adjustment frame 1.

[0061] Preferably, the rotation guide portion 11, the upper cross beam 12, the two connecting portions 13 and the two supporting portions 15 of the adjustment frame 1 are integrally formed. As an alternative, the rotation guide portion 11, the upper cross beam 12, the two connecting portions 13 and the two supporting portions 15 of the adjustment frame 1 are welded. Both can improve the structural strength of the adjustment frame 1 and reduce the number of parts.

[0062] The utility model also provides a harvester, including a header body 100 and a bridge device, and also including the above-mentioned adjustment device. Specifically, the harvester also includes the above-mentioned header device, and the header device includes the above-mentioned header body 100.

[0063] By adopting the above-mentioned adjustment device, it is possible to simplify the structure of the harvester and improve the efficiency of adjusting the angle of the harvesting table body 100 to the ground on the basis of realizing the adjustment of the angle of the harvesting table body 100 to the ground.

[0064] Among them, the specific structure of the header device belongs to the prior art and will not be repeated here.

[0065] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
