Individual normal operation interval, when its weight exceedes the upper limit of its operation interval, it is possible to block, it may be possible to crop
Kind change, it is also possible to be the reason such as humidity is excessive of crop, if the change of this weight does not cause threshing
The large change of the moment of torsion of the rotating shaft of roller（In the technical program, torque value is not reaching to the upper limit that it sets numerical value）,
Concave grate need not be then adjusted, if torque value is varied widely, i.e., torque value reaches that it sets numerical value
Maximum, then start the spacing of stepper motor, adjustment concave grate and threshing cylinder；When two values are both less than under setting numerical value
Under limit, just start stepper motor so that the spacing of concave grate and threshing cylinder reduces.The setting of the technical program causes thresing machine
Automatic, instant concave grate can be adjusted, Different Crop state can be adapted to, reduction is jumped a queue, the probability of card machine, is reduced
Threshing cylinder and its rotating shaft pressure, improves its job stability.
Preferably, described casing includes box frame and corresponding shrouding, the right side of described box frame is provided with
One side seal door, upside and the box frame of the side seal door are hinged.The right side of box frame is the regulation machine up and down of concave grate
The side of structure, as long as manual adjustment operation can be carried out with easily to upper-lower position on device by opening side seal door, use is very square
Just.
Preferably, described upper-lower position on device is provided with former and later two, the inner side of the rear and front end provided with side seal door.It is recessed
Screen is to belong to one of more large-scale and main stressed member in thresing machine, and its stability is to whole separating mechanism
For it is extremely important, the technical program is adjusted by former and later two upper-lower position on device to it, in operation and uncomplicated, and
It is highly stable reliable in structure.
Preferably, provided with two played a supporting role after being opened to side seal door between described side seal door and box frame
Individual gas spring.
The present invention the beneficial effect brought be solve the thresing machine present in prior art notch board can not according to
The technical problem that industry environment and crop situation are timely adjusted, realize it is a kind of simple in construction, easy to operate, by recessed
The adjustable threshing box that spacing between screen and threshing box is timely and effectively adjusted.
