[0039] At the same time, at least one side of the mounting bracket 2 is provided with a locking piece 5, which is movably connected to the mounting bracket 2, and when the threshing cylinder 1 is located in the threshing work station, the locking piece 5 can be connected with the fixed support structure 3 or separated from the fixed support structure 3 by moving the locking piece 5. When the locking piece 5 is connected with the fixed support structure 3, the threshing cylinder 1 can be locked in the threshing work station, so that the threshing cylinder 1 cannot be lifted to ensure that the threshing cylinder 1 remains stable during threshing operation; when the locking piece 5 is separated from the fixed support structure 3, the locking piece 5 releases the locking of the threshing cylinder 1, and at this time the threshing cylinder 1 can be lifted for blockage removal when the threshing cylinder 1 is blocked.
[0040] At the same time, the mounting bracket 2 provided with the locking piece 5 is also provided with a first position sensor 6, which is used to detect the position of the locking piece 5, so that the locking state or unlocking state of the threshing cylinder 1 can be determined by the detection result.
[0041] For example, the locking piece 5 has a locking position and an unlocking position, when the first position sensor 6 detects that the locking piece 5 is located at the locking position, it means that the locking piece 5 is connected with the fixed support structure 3, and the threshing cylinder 1 is in a locked state that cannot be lifted; when the first position sensor 6 detects that the locking piece 5 is located at the unlocking position, it means that the locking piece 5 is separated from the fixed support structure 3, and the threshing cylinder 1 is in an unlocked state that can be lifted. Before lifting the threshing cylinder 1 for cleaning, first use the first position sensor 6 to detect whether the locking piece 5 is moved to the unlocking position, so that the threshing cylinder 1 can be lifted smoothly for cleaning; when the threshing cylinder 1 is put back to the threshing work station, the first position sensor 6 is used to detect whether the locking piece 5 is moved back to the locking state, so that the threshing cylinder 1 can be stably stopped at the threshing work station during subsequent threshing operation.
[0042] Therefore, through the threshing device of the present application, not only the blocked threshing cylinder 1 can be easily cleaned, but also the threshing cylinder 1 can have a stable working state during threshing operation.
[0043] In this embodiment, preferably, the locking member 5 is rotatably connected to the mounting bracket 2 through a first rotation shaft, the axis of the first rotation shaft is parallel to the axis of the threshing cylinder 1, one end of the locking member 5 is formed with a hook, and the fixed support structure 3 is provided with a fixed pin, when the threshing cylinder 1 is located at the threshing working position, the locking member 5 is rotated to enable the hook of the locking member 5 to be hooked with or unhooked from the fixed pin of the fixed support structure 3, so as to realize the locking and unlocking of the threshing cylinder 1.

Thus, when the transmission member 7 rotates to drive the locking member 5 to rotate, the rocker arm 8 can also drive the detection shaft of the angle sensor to rotate, so as to detect the rotation angle of the locking member 5 through the angle sensor, and in turn judge whether the locking member 5 rotates to the locking position or the unlocking position.
[0047] In one embodiment of the present application, preferably, the two mounting brackets 2 are respectively connected to the fixed support structure 3 through support arms 4; specifically, one end of the support arm 4 is connected with the mounting bracket 2, the other end of the support arm 4 is rotatably connected to the fixed support structure 3 through a second rotation shaft, and the second rotation shaft is parallel to the axis of the threshing cylinder 1, so as to rotate the support arm 4 to enable the threshing cylinder 1 to be flipped up and down around the second rotation shaft, and in turn realize the lifting and lowering of the threshing cylinder 1.
[0048] In this embodiment, preferably, the threshing device further comprises a second driving mechanism fixed to the fixed support structure 3, and a driving end of the second driving mechanism is connected to the support arm 4, and the support arm 4 can rotate around a second rotation shaft under the driving of the second driving mechanism to drive the threshing cylinder 1 to overturn and lift, so as to realize the lifting driving of the threshing cylinder 1 through the second driving mechanism.
[0049] In this embodiment, preferably, the threshing device further comprises a second position sensor for detecting the position of the threshing cylinder 1.

[0050] Alternatively, the second position sensor can also be a photoelectric switch, and a sensing sheet is arranged on the support arm 4, and when the threshing cylinder 1 is located at the threshing work station, the sensing sheet is located in the sensing range of the second position sensor.
[0051] In actual operation, after the threshing cylinder 1 completes the unblocking and falls back to the threshing work station, the second position sensor is used to detect whether the threshing cylinder 1 falls back to the position, and after the threshing cylinder 1 falls back to the position, the locking piece 5 is used to lock the threshing cylinder 1.
[0052] In this embodiment, preferably, the threshing device further comprises a third position sensor for detecting the position of the cutting and threshing rod of the harvester.

On the harvester, the unloading cylinder is located above the threshing cylinder 1, and when the threshing cylinder 1 needs to be lifted to the highest position, the unloading cylinder also needs to be lifted to the highest position it can reach. Whether the unloading cylinder is lifted to the highest position can be detected by the fourth position sensor.
[0054] The unloading cylinder is also lifted by turning, and the fourth position sensor can also be an angle sensor, and the turning angle of the unloading cylinder can be detected in the manner that the first position sensor 6 detects the rotation angle of the locking member 5, and the position of the unloading cylinder is determined in turn.

Specifically, a cover plate is arranged on the chopper, and the cover plate is installed above the chopper in a manner of rotating and lifting, and the chopper can be opened or closed by lifting the cover plate, and the fifth position sensor is used to detect the movement of the cover plate to determine whether the chopper is in an open state, a closed state, or a switching state of switching between the open state and the closed state according to the detection result.
[0056] For example, the fifth position sensor can also be an angle sensor, and the rotation angle of the cover plate can be detected in the manner that the first position sensor 6 detects the rotation angle of the locking member 5, and the position of the cover plate is determined in turn. If the fifth position sensor detects that the angle of the cover plate changes, it indicates that the chopper is in the switching state, and at this time, the threshing cylinder 1 is not allowed to be unlocked and lifted.

[0058] In this embodiment, the semi-feed harvester comprises the threshing device, and therefore the semi-feed harvester has all the beneficial effects of the threshing device, which will not be described one by one here.
