The combine harvester carries the account that groove jams
From;  Author:Stand originally
Environment of combine harvester work is harsh, use undeserved when, carry groove to often can jam, light person cause cereal loss and reduce manufacturing efficiency, the person that weigh burns caustic drive belt and even make carry groovy drive shaft to rupture. The cause that will cause 4L-140 combine harvester to carry groove to jam now and solve method introduction to be as follows.

One, rotate speed respect

1, carry rotate speed of groovy drive shaft. Drive shaft rotate speed decides the linear velocity of conveyer belt directly. Speed is exorbitant, mechanical vibration is big, lower service life of machines and tools; Rate is too low, can cause when the linear velocity that is less than lamina of dragon of the agitate that cut a stage jam. Feeding especially when the amount is larger, if per unit area yield is high, reap speed water content of straw of fast, crop is big, careless cereal is compared be more than 1.5 when, cause more easily jam. Accordingly, drive shaft rotate speed should the circumstance according to harvesting crop is timely adjust, when be being reaped normally, its linear velocity is 1.2-1.5 rice commonly / second.

2, rotate speed of dragon of the agitate that cut a stage. The main effect of dragon of the agitate that cut a stage is the crop that is put before cutting a stage will be made the same score after cut, carry through blade carry notch, shrink by agitate Long Shen again lever to carry groove to be fed. If the linear velocity of agitate dragon exceeds the linear velocity that carries groovy conveyer belt, carry groove to be able to jam when agitate dragon full load works. Of course, the linear velocity of agitate dragon also cannot pass small, cause agitate dragon easily to jam otherwise and make feed a volume ignore big ignore small, cause threshing ungodliness, depart is not clear. Accordingly, the rotate speed of dragon of the agitate that cut a stage should be less than the 10-15% that carries linear velocity of groovy driving pulley commonly, the linear velocity when be being reaped normally is 1.05-1.30 rice commonly / second.

3, the rotate speed that dials standing grain annulus. The action that moves standing grain annulus is above all dial crop come to tilt backward, it is to give aid to crop facilitates next cut, finally is cut the crop after is made the same score put in cut a stage to go up. If dial rotate speed of standing grain annulus too fast, with reap speed to be not coordinated, the successive stroke that crop is played tine axis possibly when reap and comb brush, generation seed bead falls off, cause a loss. If dial rotate speed of standing grain annulus too low, when the axis that shoot a tooth-like part of anything is moving downward, can appear wait for cut crop to be in cut the situation that is played to age be pushed before axial between stage and cutter, both neither benefit is opposite at cutter the regular cut of crop, can cause again already cut crop to scatter or be in in the ahead that cut a stage accumulation stops on cutter, cannot be carried in time by agitate dragon, wait for accumulation to arrive when certain level, partial crop enters brim of agitate dragon lamina, be fed by agitate dragon adjustable lever, make the instant feeds a quantity to increase, cause carry groove to jam. Accordingly, dial rotate speed of standing grain annulus to should be adjusted accordingly according to reaping speed to do, the rotate speed when be being reaped normally turns for 30-40 commonly / cent.
