Rice transplanter technical adjustment is more complex, the main is the adjustment of two parts, one is the adjustment of transplanting part of the work, and the other is the adjustment of the performance of the whole machine. The following is an example of the Dongyang brand pf455s rice transplanter. First, the adjustment of transplanting part 1, adjust the planting distance The adjustment of the planting distance of the transplanting is accomplished by adjusting the position of the planting distance adjusting handle. The spacing adjustment handle has three gear positions to adjust, namely 70, 80, 90 three gear positions. It means that there are 70 holes, 80 holes, and 90 holes per 3.3 square meters. The plant spacing is 16 cm, 14 cm, and 12 cm, respectively. The total number of holes per mu is 14,000, 16,000, and 18,000. Adjust the technical method. If the engine is running at idle speed, push or pull the pitcher adjustment handle to the appropriate position. At this time it should be noted that the adjustment handle must be fully integrated. Otherwise, part of the planting agency will not work properly. 2. Adjustment of the number of holes The number of holes is determined by the area of ​​the picking block taken by the rice transplanter. It is related to the size, height and width of the block. Therefore, the adjustment of the number of holes is composed of three aspects: the amount of earthworms taken horizontally, the amount of earthworms taken vertically, and the amount of earthworms fed. The adjustment of the horizontal picking amount is to adjust the width of the picking block. The amount of lateral picking can be adjusted in three gears, 20, 24, and 26. It means that the transplanter takes 28, 28, and 28 centimeters laterally when it is picked up. The number of picks and picks are 28 divided by 20, 24, and 26 equal to 1.4, 1.17, and 1.08 centimeters. To adjust the technical method, when the seedling box is moved to the left or right, the planting clutch is set to the connected position, the engine is turned off, the circular plate is rotated, the number on the circular plate is turned to the bolt opening, and bolted can. Vertical adjustment of the amount of picking, that is to take the height of the block adjustment. There are 10 gears with 8-17mm in the vertical direction and 1mm adjustment for each gear. It is achieved by adjusting the position of the seedlings to transfer the support box hole and the length of the seedling transfer screw. When the vertical take-off amount adjustment handle is located at 8 to 11 mm, it corresponds to 3 holes, the lowest hole. Located 11 to 15 mm, corresponds to 2 holes, the middle hole. Located at 15 to 17 mm, corresponds to 1 hole, the top hole. 3. The adjustment of the depth of the insertion can be selected by changing the position of the adjustment handle. The depth of the insert is changed by 6mm per file. You can also select 6 positions by changing the jack that the floating plate is connected to the machine. When adjusting the positions of the jacks to which the floating board and the machine are connected, the jack positions of the main floating board and the auxiliary floating board must be adjusted accordingly. Second, the transplanter machine performance adjustment After a period of operation of the rice transplanter, there will be some changes in the performance and technical conditions of the machine, and some adjustments must be made in order to maintain normal operations. General inspection adjustments are 1ã€Adjustment of engine belt The adjustment method is to loosen the four base bolts of the engine first, and the engine is moved forward until the belt tension meets the requirements, that is, press down a 10-15 mm with a finger, and then tighten the four base screws. 2, the adjustment of the spark plug Remove the spark plug first and check the electrode gap. The electrode gap is 0.6 to 0.7 mm. The electrode is dry and clean, free of oil and dirt. Otherwise, the gap should be adjusted and cleaned. 3, carburetor adjustment Pulling the throttle, throttle cable, throttle, and throttle switch should be normal. When the throttle is closed, the main spout is fully closed and the idle spout is fully open. The idle screw is screwed inward and the idle speed is reduced until it is closed. Unscrew the idle screw and turn it higher. During the adjustment, after the idle screw is tightened, it is quitted by one-half turn and can be fine-tuned as needed. 4, adjust the planting chain The method is to loosen the tensioning mechanism of the main gear box, first adjust the tensioning screw at the planting gear box, so that the chain is pre-tensioned, and then the front main gear box tensioning mechanism is rotated counterclockwise to tension the chain. 5, adjustment of body balance When the left and right unbalance of the rice transplanter occurs, the machine is rocked 4 to 5 times, and when the height difference between the left and right sides of the guide rail is greater than 10 mm, the adjusting nut on the dummy linkage arm is adjusted to maintain the balance. When adjusting, first park the machine on a flat place, place the seedling box in the middle of the guide rails, raise the machine and shake it from side to side, and confirm after parking for 2 to 5 minutes. 6, the adjustment of the control cable A adjustment of the main clutch handle pull wire, the main clutch handle has 'connected and disconnected' two operating positions. When adjusting, tighten the cable until the main clutch is connected and start working in the position of 'Cut'. The adjustment of the B planting clutch handle pull wire has two operating positions of 'connected and disconnected'. When adjusting, tighten the cable until the plug-in clutch is connected and start working in the position of 'cutting'. The adjustment of the C safety cable and the adjustment of the safety cable are mainly to ensure the security function of the rice transplanter and prevent it from being inserted in the traveling file. The adjustment requirement is that when the shift lever is located in the travel gear, the plug-in clutch is turned on, and the shift lever automatically jumps to the plug-in gear as a standard. D Adjustment of the hydraulic lifting handle pull wire. The hydraulic lifting handle has three operating positions: 'rise, fall and neutral'. The valve arm is in contact with the rear boss when it is raised, and the valve arm is in the front and rear boss positions when it is fixed. During the adjustment, when the hydraulic lifting handle is at the 'up' position, the machine starts to rise, and the speed of ascent and descent is up to the standard. The rise time is 3 to 4 minutes, and the fall time is 1.5 to 2 minutes. E. Adjust steering clutch cable. When adjusting, first check to see if the clutch is working. If you hold the handle and then release it, if the handle can not return, you should shake the machine and observe whether the handle is returned. Adjust the handle gap to 0 to 1 mm when adjusting. 7. Adjusting the gap between the needle and the seedling The method is to loosen the crank fixing pin and the rocker fixing nut of the planting assembly and move the planting arm left and right so that the clearance meets the requirements of 1.3 to 1.7 mm, and then the planting arm crank is fixed, and the rocker and the bearing housing are fixed. After adding or removing spacers, fix the rocker. 8, the adjustment of the gap between the needle and the seedling box The gap between the needle and seedling box is about 1.5 to 2.5 mm, and it is symmetrically distributed. When adjusting, loosen the seedling box and the light bar fixing screw and move the seedling box left and right so that the clearance meets the requirements.
