Second, the use of harvesters safety precautions Use of combine harvester, must comply with safety and technical rules to ensure personal and machine safety. Persons untrained and unqualified are not allowed to drive the combine. Before starting the engine according to regulations, check in advance that the shift lever position, the threshing clutch handle, and the unloading clutch lever handle are in the disengaged position. Before the engine starts and the clutch is engaged, signals must be given to ensure safety. During operation, it is not allowed to touch the working parts of the harvester. Various adjustments and maintenance can only be performed after the engine has stopped running. After parking, it is necessary to change the neutral gear and cut the threshing clutch. When the harvester is in operation, people are prohibited from entering the grain tank. When working under the header and under the bridge, the header safety device should be locked to prevent the header and bridge from falling accidentally. The stalk debris and other flammable substances that remain around the engine are cleaned in time to eliminate the oil leakage of the engine fuel and the hydraulic system. Always check the connection and insulation of the conductors. The circuit conductors must not be stained with oil. When welding, turn off the main power switch. Harvesting must always be done with a large throttle to ensure stable operation of all systems. Harvesters equipped with two fire extinguishers, should pay attention to the timeliness of fire extinguishers during transportation on the highway, the header lock cylinder locking device should be used when operating the harvester uniform necessities, in order to ensure safety attention to the various warning signs on the machine, we only Warning signs have been added in some important areas. Third, commissioning, maintenance The engine has been in the factory for two hours before the commissioning operation, without formal running-in, the significance of running-in is: to reduce the relative movement of certain parts of the friction surface of the micro-unevenness, extend the life of the machine , Early detection and handling of certain possible failures. The method of running-in is: 1. Start the engine with the throttle and gradually increase the throttle to high-speed idling within 5 minutes. 2. The engine requires load running-in, and the threshing part also needs to run-in. Therefore, it is necessary to have a contract with a threshing mill for 5 hours. 3. The gear drive of the walking part also needs to be run-in. Therefore, each gear should be hung up and down for about 8 hours. Please note that the engine must be running at high speed. During the running-in, observe and check the oil pump, oil pressure, gear oil, cooling water volume, water temperature, the tension of the drive belt and chain, and the following conditions: After a regular stop, touch the heat of each bearing, the bearing is hot It is an abnormal situation. Pay attention to hearing abnormal sounds everywhere and handle them in a timely manner. During this period, certain bearings and chains are to be maintained and lubricated. Fourth, the working principle of each system and adjustments 4.1 Header use and adjustment The role of the header is to complete the cutting and delivery of crops, the general header cutting range has two options, namely 2.75 meters and 2.5 meters, soybean cutting Taiwan is an overall flexible header, cutting width is 2.75 meters, header performance, reliability, superior to similar models. The following describes the use of ordinary headers. According to the needs of the local grain harvest, the cutting height is selected by the operator, which is adjusted by lifting the header. Generally, the cutting height is between 100 and 200 millimeters. When permitted, the cutting should be as high as possible, which will improve the efficiency of the combine harvester. The adjustment of the reel wheel and the use of eccentric spring-type reel wheel are excellent, and the ability to harvest lodging crops is strong. It is incomparable to other similar models. It has a number of adjustments, please pay attention to use. 1. There are two adjustments of reel speed, one is the chain drive, the chain is connected to the sprocket with different number of teeth, different speed can be obtained; the second is the belt drive, the opening degree of the belt pulley can be adjusted, and two bolts are passed through. The opening of the belt pulley can be adjusted and the belt can be tightened again after adjustment. 2. The choice of the reel speed depends on the host's travel speed. The faster the travel speed is, the faster the reel speed should be. Conversely, the reel speed should be slower. In general speaking, the reel should be moved slightly backwards and the crop should be placed on the header smoothly, avoiding the loss of the shredding wheel due to excessive rotation speed. 3. The height of the reel should be adapted to the height of the crop and adjusted at any time by means of hydraulic handles. In order to transport the crops smoothly, the reel rake should be toggled at the center of gravity of the crop to be cut, ie it should be allocated from the cut. At approximately two-thirds of the height above, the basic requirement for the use of headers is to ensure balanced crop transport. 4. When harvesting fallen crops, the reel should be adjusted to a very low position while the header is lowered. The reeds on the reel can be very close to the ground, and the speed of the reel relative to the host is high. In this case, the spring teeth will lift the fallen crop and cut it. 5. In order to adapt to the requirements of different straw lengths for common varieties, the adjustment range of the front and rear positions of the reel wheel is relatively large. Generally, harvesting short straw crops such as rice and wheat should adjust the position of the reel to the first, second, or third hole in the back of the positioning hole of the support arm so that the distance between the reel and the central auger can be reduced. Become smaller, prevent accumulation, and feed smoothly. 6. The reed-tooth tine tube is equipped with a number of spring teeth, which can be adjusted by the eccentric device. In general, the spring tooth direction should be perpendicular to the ground. When harvesting fallen crops or harvesting sparse dwarf crops, it should be adjusted so that it is tilted backwards, which is conducive to the transport of crops. The adjustment method of the spring teeth direction is to loosen the two adjustable Bolt, move the eccentric disk, the direction of spring teeth can be changed, then, tighten the nut. 7. The reel support bearing is a sliding bearing. To prevent wear caused by lack of oil, the bearing should be filled with oil once or twice a day. The cutter's adjustment and use of the cutter is reciprocating and has a strong cutting ability. It can adapt to a working speed of 10 km per hour without any missed cut. The moving blade adopts a tooth-shaped self-sharpening structure, and the blade is assembled on the arbor with a rivet, and the diameter of the rivet hole is 5 mm. The reciprocating arbor in the guard must have a certain clearance in the front and rear direction. If there is no clearance, the arbor movement is hindered. If the clearance is too large, debris will be stuffed in the clearance and the movement of the arbor will be blocked. The gap between the front and back of the tool bar should be adjusted to approximately 0.6 mm. The adjustment method is as follows. Loosen the bolt on the cutter beam and move the friction piece forward or backward to adjust the gap of the cutter bar. The gap between the moving blade and the stationary blade is a cutting gap, and the size of the cutting gap should be 0-0.8 mm. When adjusting the gap, you can use the hammer to hit the blade guard up and down, or you can adjust the gap between the blade guard and the blade. Rocker arms and ball joints are parts with a large amount of vibration. Each day, the three grease nipples should be filled with oil. The adjustment of the central auger and the use of the central auger and its telescopic gears and the header body constitute the auger, and the adjustment of the central auger position and the conveying gap can make the feeding of the crops smooth. 1. If there is accumulation in front of the auger, move the central auger forward and downward. Adjustment method is: Loosen the adjustment board bolts on both sides, move the adjustment board, the central auger also moves with it, the two sides of the gap should be consistent, after adjustment to tighten the bolts, and to re-adjust the tightness of the drive chain. 2. If the operation of the central auger causes the back of the grain, the central auger can be moved backwards so that the gap between the auger blade and the anti-wrapper becomes smaller. 3. If there is a blockage between the central auger blade and the header floor, the gap below the auger blade can be reduced and adjusted by the auger adjustment plate. 4. The smaller the gap between the telescopic tooth and the base plate, the stronger the gripping ability, the gap can be adjusted to 5 ~ 10 mm. The adjustment position is the adjustment handle on the right side. After loosening the bolt, move the telescopic tooth downward and move the telescopic tooth downward. Adjust the bolt and tighten it. 5. In order to avoid the failure due to the central auger plugging, a friction plate type safety clutch is installed on the drive shaft of the auger. The length of the spring is installed to a length of 37 mm. This is the factory state. It can be adjusted according to the actual situation. The tightness should be such that the friction plate does not slip during normal operation. When the central auger is blocked and the torque is too high, the friction plate slips. The safety clutch is dry and do not add lubrication. Unusable. Use of inclined conveyors (bridges) to adjust the bridge to connect the header to the main machine and transport the grain with the conveyor chain and chain conveyor to drive the active roller of the conveyor chain. Its position is fixed, the passive roller The location is uncertain, with the amount of grain floating, under the action of springs, floating roller and its chain, always compacting crops, forming a smooth grain flow. 1. During the non-work gap, small grain crops such as rice and wheat should be harvested. The distance between the sprocket teeth and the floor of the bridge under the floating roller should be 3 to 5 mm. When harvesting large grain crops such as soybeans, the gap should be 15 to 18 mm. The adjusting part is on both sides of the bridge, and the nut on the upper end of the spring can be adjusted. Rotate clockwise, the dancer roller moves upward; otherwise, the dancer roller moves downwards. 2. Adjustment of pre-tightening degree of conveyor chain: Open the inspection port and lift the chain upwards with the power of 15 kg. The conveyor chain should be increased by 20-35 mm. Otherwise, adjust the adjustment bolts on both sides of the bridge to adjust the front and rear position of the floating roller. The tightness of the conveyor chain is suitable. There is an anti-wrapped plate on the drive shaft of the bridge. Do not remove it.
