Inconsistent feeding: The position of the puller wheel is too far from the feeder to feed the auger, the distance between the agitator blade and the bottom plate in the middle section is too large, the distance between the feed key and the retractable tooth tip does not match, and the crop is lodging or damp .
Adjustment method: First, under the premise that the elastic teeth do not touch the cutter, the pull-out wheel should be moved as far as possible. Second, repair the header to feed the apron blade, so that its height is restored to normal. Third, the distance between the feed chain and the telescopic tip is kept at 10-15 cm. 4. The spring length of the auger's safety clutch to be fed by the header is to be suitable. When the feed resistance is too large, it can be separated in time.
The reason for the blockage of the trough is that the tension of the conveyor belt is not enough or there is a phenomenon of side running, the trough of the trough is more, and the stem of the grain is wet.
Adjustment method: Clear the plug and tighten the belt. When it is determined that the belt wear is not enough to transmit power, it should be replaced in time. Such as wheat straw excessive moisture, reduce the width of the cut width or wait for the straw to dry after harvest.
Threshing roller clogging cause: The belt is too loose or unevenly fed. The crop is thick and the stems are wet. Adjustment method: First, tighten the belt. Second, control the header feeding amount. Third, use the medium and large throttle to work. Fourth, choose mature dry crops to harvest or increase cutworms.
The reason why the threshing is not clean is that the crop is growing well and the forward speed is too fast. The threshing part has a large gap between the slats and the concave plate, and the rotational speed is low.
Adjustment method: First, control the speed of advancement, and the cut length of the wheat field block should be controlled within 2/3. Second, adjust the threshing machine threshing gap, wear parts should be replaced in time. Third, tension the power machine to move the threshing parts of the belt.
There are many reasons for the loss of grain in the field: the wheat is too mature and the straw is too dry. Threshing parts tile screen opening large.
Adjustment method: First, select the appropriate mature field harvest. Second, narrow the gap between the threshing tile screen, the screen opening to maintain no more than 2/3, under the screen opening is generally not less than 1/3. Third, the thresher to the ground should be quickly raised header, large throttle to send the remaining wheat in the trough. The average field standard grain loss is maintained at around 5%.
