1. Pressing, pressing, pressing, pressing, and pressing are the pressing of the inner side of the harvester to the inner row of crops adjacent to it. Some push the crop down to the ground, and some push the crop forward, causing difficulties in harvesting. Loss of grain. Crimping is usually caused by improper positioning of the internal divider. If the tip of the internal branching device is too far in relation to the cutting width, the crop within the cutting range does not divide these crops into the cutting area, but is outside the cutting area and the crew is moving forward. That is overwhelmed or pushed obliquely. If the tip of the internal branching device is excessively located relative to the cutting width, then the culm other than the original clipping width is divided into cuttings by the dividing device, resulting in high cutting of the line. The exclusion method is: correct the position of the two tiller tips according to the cut amplitude, so that the distance between the two minute picks is slightly larger than the cut width. In addition, the tip of the bifurcation should be perpendicular to the lever of the corresponding edge guard and not tilt the bifurcation.

2. Pushing a rake is pushing a rake to push its front crops to the ground. The main reasons for pushing are: 1) the transverse dimension of the tip of the bifurcation device is too large; 2) the position of the tip of the bifurcation device is skewed; 3) the front of the bifurcation device is covered with grass, mud and other debris; 4) the position of the tip of the bifurcation device is too low . Remedy: The main task is to examine the bifurcation device, make necessary corrections to the shape and position of the tip, and remove debris hanging on the bifurcation device to facilitate the insertion of crops and allow the crop to slide along the bifurcation. The front-to-tail of the entire divider should be conducive to crop gliding. There are no defects such as blocking or hooking the mast. This is the basic requirement for the divider.
3. The grass harvester works in the fields where there are many weeds, sometimes weeding on weeds, and accumulating more weeds, which seriously affects the tillering and has a pushing effect on the front crops. operation. Causes of hanging grass are: 1 weeds in the field are numerous and long; 2 weeds are damaged, weeds cannot slide; 3 weeds and weeds are too wet and stick on the tillers; 4 some of the divider lids The backward expansion angle of the plate or frame is too large to cause the weeds to slip backwards. The exclusion method is: 1 Raise the machine cutting table so that most of the weeds will not be cut to reduce the weeding and cutting of weeds; 2 to avoid the harvest of wet crops; 3 to lengthen the divider, reduce the cover or frame Backward expansion angle; 4 Check the splitter structure and remove the damaged components.
4. The harvester that has been cut and unclearly separated and has normal operations can cut off all the crops that are sent to the cutting area, and one crop outside the cutting area does not cut off. If the edge of the edge guard does not coincide with the rear end of the bifurcation rod or the clearance between the two is too large, inconsistent bifurcation and cutting will occur, ie heavy cutting or missing cutting will occur. Remedy: As long as the correct installation of the bifurcator, pay attention to the guard blade tip and the rear end of the bifurcator bottom rod overlap, or position close to no larger gap.
5. The entwined and uncut crops are intertwined. The current crops are very long, reaching 1.2 to 1.4 m. The existing harvesters on the harvester usually can only adapt to 1.1 m or less, and the crops are originally intertwined with each other. Under such conditions, the cut crops and uncut crops can not be completely separated from one another and intertwined with each other. , resulting in crop chaos. For higher crops, it is generally advisable to increase the length of the height-raising device. The degree of heightening should be sufficient to open the part of the crop and avoid division of the head.
Second, the pull out of the fault and remove it
1, pull out the wheel hit the grain too much 1 reel speed is too high. At this time, the reel speed should be reduced. Practice has proved that when harvesting wheat, the reeling line speed should generally not exceed 3m/s. The ratio between the reel speed and the harvester's forward speed should be within the range of 1.1 to 1.7 and must not exceed 1.7. Otherwise, it will cause multiple impacts on the crop and increase losses.
2 The position of the reel wheel is too high, causing the spring pin shaft to hit the head. In this case, the reel height should be reduced. The correct height is such that when the reel's spring tooth is inserted into the crop, there will be no impact on the crop, and when the revolver axis is at the lowest position, it will hit 2/3 or slightly above the crop to be harvested. Therefore, when harvesting low or low crops, the reel should be lowered to a lower position. At this time, attention should be paid to: Do ​​not scratch the cutter and the header auger (auger) with a clearance of at least 25 mm. Also note that the high and low positions on both sides of the reel should be consistent. This can be adjusted by adjusting the adjustment bolts of the long drop cylinders on the left and right sides of the reel.
3 The reel was too far forward, and the spring pinion hit the crop too often, causing too much loss of grain. The solution is: move the reel afterwards. The specific method is to loosen the tension pulley of the transmission belt, remove the triangular tape, and then remove the fixing bolts worn on the arm, and then move the reel. At this time, attention should be paid to the position of the left and right reel axles. After adjusting the front and rear position of the reel, the triangle tape should be properly tensioned, otherwise the pull-out wheel speed will be reduced.
2, reel wheel with grass 1 reel position too low or too high speed. Solution: Increase the reel position or lower the reel speed.
2 The reclining angle of the reel spring is too large, and the revolute angle should be adjusted. The adjustment of the angle of reel teeth should be different depending on the specific circumstances of the crop being harvested. When harvesting upright crops, the springs should be perpendicular to the ground in order to reduce the impact of the springs on the crops; when harvesting the fallen crops, the springs can be adjusted to tilt back 15 to 30 degrees to enhance the extraction of the springs. Capacity; When harvesting tall, dense crops, the spring teeth can be adjusted forward to increase the distance between the spring teeth and the auger blade, facilitating the harvester to transport the crop.
3. The reason why the header of the header truck is blocked by the reel wheel is due to the improper position of the reel wheel. The front and rear position of the reel wheel has an impact on pushing the crop back. After the crop is cut by the cutting knife, the reel wheel is turned on the cutting table, and the reel wheel is moved relative to the header to make a circular motion. When the crop is tangent to the orbit of the reeling tooth, the angle between the stem and the plumb line is Called the push angle. Practice has shown that when the reel is retracted, the pushing angle becomes larger, which is advantageous for the crops that are cut off; the forward reeling wheels have smaller pushing angles, which are unfavorable to the crops that are cut off, and are prone to clogging. From this, it can be seen that properly adjusting the front and rear positions of the reeling wheels is crucial to the normal operation of the header auger. Therefore, when retrieving forward lodging crops, the reel should be moved forward and down; when harvesting upright crops, the reel axle should be located near the top of the cutter; when reversing crops are harvested, the reel should be moved slightly , to prevent the reel from pressing the cut crop under the cutting table.
First, the breakdown of the bifurcation device and its exclusion method In many parts of the harvesting machine, the bifurcation device is the simplest component of the structure. However, because it is located at the forefront of the implement, it is easily damaged in the field turning and transferring the field. In addition, the delivery device is usually inserted into the middle of the crop. If it is improper, it can lead to poor operation of the machine, loss of grains, and other ills. For this reason, it cannot be negligent because of its simplicity. The causes of the common breakdown of the delivery device and its exclusion methods are described below:
