[0055] Embodiment 2

[0056] The embodiment describes a harvester. Referring to Figures 1-4The harvester comprises a harvester body 2 and a grass cutter body 3, a transmission structure and an adjusting structure, wherein the transmission structure comprises a plurality of transmission wheels arranged on the harvester body 2 and the grass cutter body 3 and a conveying belt 17 arranged around the outer surfaces of the transmission wheels, and the adjusting structure is the adjusting structure described in Embodiment 1, wherein the tensioning wheel 5 is in abutment with the outer wall surface of the conveying belt 17 in the tensioning state.

[0057] The harvester in the embodiment has a grass cutting state and an avoiding state, in the first position, the grass cutter body 3 is connected with the harvester body 2, so that the harvester is in the grass cutting state, in the process of switching from the first position to the second position, the conveying belt 17 is adapted to be separated from the transmission wheels, i.e. the conveying belt 17 is detached from the harvester body 2 and the grass cutter body 3, and the feeding port 301 of the grass cutter is adapted to be away from the discharging port of the harvester body 2, so that the harvester is in the avoiding state.

[0058] The harvester in the embodiment adopts the adjusting structure described in Embodiment 1, thus having all the beneficial effects thereof, and the harvester in the embodiment can meet the use requirements of whether to cut grass, and is convenient for adjusting the position of the grass cutter without the need of detaching the grass cutter from the harvester body 2, thus being convenient for use.

[0059] In order to improve the connection stability between the grass cutter body 3 and the harvester body 2 when the grass cutter body 3 is in the first position, a mounting assembly can be further arranged between the harvester body 2 and the grass cutter body 3, the mounting assembly comprising at least one first mounting member 9, the first mounting member 9 being adapted to connect the harvester body 2 and the grass cutter body 3 when the grass cutter is in the first position, and the first mounting member 9 being adapted to be separated from the grass cutter body 3 when the grass cutter body 3 is switched from the first position to the second position, so as to release the constraint of the first mounting member 9 on the grass cutter body 3.

[0060] In specific application, the first mounting member 9 is a mounting base arranged below the harvester body 2, the mounting base being connected with the harvester body 2 and the grass cutter body 3 through fasteners, and when it is required to switch the grass cutter body 3 from the first position to the second position, the fasteners between the mounting base and the grass cutter body 3 are detached, so as to realize the constraint of the first mounting member 9 on the grass cutter body 3.

After gradually rotating, the first plane is parallel to the second plane, and the operation of the position adjusting member 8 is stopped.

[0064] Of course, after the above-mentioned cutter body 3 is switched from the first position to the second position, the first plane 302 of the cutter body 3 can also have an angle relative to the second plane 201 of the harvester body 2. In the state of the angle, the second mounting member is used to connect the harvester body 2 and the cutter body 3 to ensure the stability of the cutter body 3 relative to the harvester body 2, and the angle between the first plane 302 of the cutter body 3 and the second plane 201 of the harvester body 2 is determined according to different crops, that is, the specific position of the cutter body 3 in the second position is determined according to the actual use state.

The angle between the first plane 302 and the second plane 201 of the harvester body 2 is not limited.

[0065] In order to avoid the rotation of the cutter body 3 relative to the harvester body 2 in the second position, the harvester in the embodiment further comprises a limiting member 11, which is arranged between the second mounting member 10 and the harvester body 2 and the cutter body 3 respectively in the second position, and a mounting connecting part 12 is arranged on the harvester body 2 and the cutter body 3, the two ends of the second mounting member 10 are connected with the mounting connecting part 12, and the limiting member 11 is adapted to be inserted on the mounting connecting part 12 to prevent the rotation of the second mounting member 10 relative to the harvester body 2 or the cutter body 3.

In specific use, the reference member 1 comprises a reference part 101 and a reference connecting part 102, wherein the reference part 101 is fixed on the harvester body 2, one end of the reference connecting part 102 is connected with the reference part 101, and the other end is connected with the cutter body 3, and the reference part 101 and the reference connecting part 102 are both in the form of a plate, and a carrying table is arranged on the connecting part for carrying the adjustment driving part 601.

[0068] In the embodiment, the transmission wheels arranged on the harvester body 2 and the cutter body 3 can be a driving wheel 13, a tensioning auxiliary wheel 14 and a driven wheel 15 respectively, wherein the driving wheel 13 is arranged on the harvester body 2, the driven wheel 15 is arranged on the cutter body 3, and the tensioning auxiliary wheel 14 is arranged on the harvester body 2, the conveying belt 17 is sleeved on the outer wheel surface of the driving wheel 13, the tensioning auxiliary wheel 14 and the driven wheel 15, and the tensioning wheel 5 is arranged on the other side of the conveying belt 17 relative to the tensioning auxiliary wheel 14.
