1. The purchase of rice transplanters is the right choice for motorized rice transplanters. Different types of rice transplanters should be selected for different uses. Can choose from the following aspects: 1. Appearance Quality. First check the quality of the motorized rice transplanter cover. The paint film does not fall off, the surface gloss shines, and the plated parts of the electroplating parts are firm without falling off; the welding is firm and reliable, and there are no defects such as burn-through, open welding, and flash burr. The surface of the casting should be smooth and smooth, free from holes, and have no defects such as sticky sand; technical data such as connecting parts, wearing parts, spare parts, and manuals are complete. 2. Test run check. (1) Turn the working part by manual method, put the main clutch in the engaged state, set the shift handle to neutral, check the working condition of the working parts, and the planting arm should not be stuck. (2) Turn the plug clutch handle away to start the engine. Before starting, add fuel and lubricants as required. After the engine runs smoothly, use the middle and slow speed to make the rice transplanter work idle for 10 minutes, and test the car with the transplanting speed and walking speed for 30 minutes. (3) When the engine is running, there is no abnormal sound, the rotation speed is stable, no black smoke, no engine oil, no resonance. 3. Check the "three leaks." Check the air filter, cylinder block and cylinder head joints and other airtight; there is no leakage in the joint surface of the oil pan, gearbox, working transmission box, working chain box, etc.; oil plugs do not leak oil. 4. Other parts of the inspection. (1) The steering should be flexible; (2) Each control mechanism is engaged and separated reliably. Gearbox, working gearbox within the rated speed, with the help of the clutch gear position should be flexible and reliable, smooth pick-up, no off, jump and other phenomena, no abnormal sound; (3) positioning clutch should be accurate and reliable. The correct position is: pull the plug positioning clutch handle, and the planting arm stops immediately above the door. When the positioning clutch is inserted, the planting arm is not allowed to touch any relevant parts during the operation of the planting arm; (4) The depth adjustment mechanism should be flexible. When the lifting rod rotates, the depth and depth of the plug can be smoothly adjusted; (5) The safety clutch is a safety device for the planting arm and the plug-in mechanism. Separation on the safety clutch is automatically blocked when blocked, causing the planting arm to stop transplanting immediately (a thin piece of wood can be placed on top of the planter's door to allow the planting arm to rotate, such as the planting arm to stop, indicating that this group of safety clutches is reliable); (6) change The agency should be accurate. When the cassette moves to the left and right limit positions, the lateral displacement stops and the reversing is completed; (7) Inspection of the delivery mechanism. The pushing stroke of the planting arm is 18-20mm, and the clearance between the pusher and the separating needle is between 0.5-1mm, the clearance is too large, the clamping jaw or the rake is clamped. The clearance between the door and the separation needle is between 1.25-1.75mm. When the machine is in operation, you can manually control the presser foot and gently turn it from left to right. If there is sound, it indicates that this group of arms is not qualified. After the above checks, if the indicators meet the requirements, then the quality of the rice transplanter you choose is reliable. Second, the correct use and maintenance (1) Before transplanting every season, the transplanter machine should be a comprehensive inspection and maintenance, according to the instructions, refueling must be refueling; (2) before use, must check all parts of the machine If there is any abnormality in the state of the technology, it must be adjusted well and the engine oil should be added to each rotating part and relative movement part. (3) During the operation, the machine's technical state must be paid more attention, the resistance is large, and the quality of transplanting is reduced. Or each part of the work is not normal, should stop the inspection, find out the reasons, adjust and repair. For every 4-6 hours of work, lubricate the rotating parts according to the requirements; (4) After the daily operation, wipe the machine clean, and check whether the machine parts are damaged, deformed, loose screws, and note that (5) When walking on land, avoid collisions to avoid breakage or deformation of separating needles, sliding doors, and other parts; (6) After the season is finished, the machine must be washed, dried, oiled, rusted, and stored. In a dry place indoors. Do not store debris on the machine to avoid deformation or damage.
