The two grass discharge blocking sensing devices 1 are provided in order to improve the accuracy of identifying whether the harvester is blocked.
When the number of the grass-discharge blocking sensing devices 1 is at least three, reference is made to the above description of the case where the number of the grass-discharge blocking sensing devices 1 is two, and the description thereof will not be repeated here.

When the working main clutch 3 and the gap bridge clutch 4 are disconnected, and the harvester can work normally after the staff solves the problem of blocked straws and the like. That is, when the harvester works, the blocking can be found at the initial stage of blocking and the response can be timely made, namely, the working main clutch 3 and the gap bridge clutch 4 of the harvester are controlled to be disconnected, the blocking degree can be effectively reduced, the time for workers to solve the blocking problem is shortened, and the working efficiency of the harvester is improved.

When the harvester is blocked, the elastic piece deforms to enable the magnetic steel 12 to be close to the magnetic induction proximity switch 11, and when the distance between the magnetic steel 12 and the magnetic induction proximity switch 11 is smaller than a preset distance threshold value, the magnetic induction proximity switch 11 continuously sends an electric signal for representing the blocking to the controller 2.
Optionally, in the above technical solution, when the distance between the magnetic steel 12 and the magnetic induction proximity switch 11 is not less than a preset distance threshold, the magnetic induction proximity switch 11 does not send an electrical signal for characterizing the blockage.
Wherein, the installation positions of the magnetic steel 12, the magnetic induction proximity switch 11 and the elastic piece should ensure:

When the magnetic steel 12 approaches the induction surface of the magnetic induction proximity switch 11, that is, when the distance between the magnetic steel 12 and the magnetic induction proximity switch 11 is smaller than the preset distance threshold, the signal end of the magnetic induction proximity switch 11 generates a continuous electric signal to be transmitted to the controller 2 for representing that the blockage occurs.

The arrangement can prevent sundries such as broken stones entering the harvester body from false triggering of the grass discharge sensing device during operation.
That is, when the harvester is jammed, the controller 2 receives the electric signal continuously transmitted from the straw-removing jam sensing device 1, and when the controller 2 determines that the continuous transmission time of the electric signal of at least one straw-removing jam sensing device 1 exceeds the preset time threshold, then the controller outputs the electric signal to the hydraulic solenoid valves of the working main clutch 3 and the gap bridge clutch 4, so that the working main clutch 3 and the gap bridge clutch 4 are disconnected, and the harvester can work normally after the worker solves the problem of the jammed straw.
