Analysis and Elimination of Common Troubles in Motorized Transplanter

1. The reason why the separation needle collides with the door is: dislocation of the fontanelle; incorrect installation of the planting arm; wear of the inner hole of the crank arm; separation of the upturned needle; excessive adjustment of the amount of the diaphragm; wear of the shaft of the pendulum shaft or wear of the lower hole. Remedy: Reset the fontanelle and fix it; adjust the planting arm to the correct position; replace the worn crank or chain shaft; correct or replace the separation needle; replace the oscillating rod or oscillating rod shaft and bearing; 2. The reason why a certain group of planting arms do not work: The chain box drive shaft is broken; the chain is out of stock or broken. Remedy: Attach the chain; replace the drive shaft. 3. Reasons for the switchboard: The slider or the chute wears; the fixed bolts at the two ends of the door are loose; the doorway is deformed; the lift is too high; the caster wheel is rusted; and the caster wheel screw is deformed. Remedy: First replace the roller and screw, and then check the slider chute, if serious wear and tear, should be replaced; Correction of the door fixing screw; If the door is fixed at wear, you can add a rectangular gasket; When the handle is too high, use Lift the handle and lift the front end with a new bumper. 4. Causes of non-working: The pin or spiral shaft is worn; the sliding sleeve fixing bolt is missing. Remedy: Open the working gear cover, replace the finger pin or screw shaft; if the slide sleeve fixing bolt is missing, it should be reinstalled. 5, send 秧 lift the back end is too high Cause: The rubber buffer block is missing or damaged. Remedy: Pick up the front end of the handle with a screwdriver and install a new bumper. 6. The reason why the crucible shaft does not rotate is that: the ratchet wheel wire pin falls off; the ratchet wheel groove wears; the pawl or the torsion spring falls off; and the crucible shaft axially moves. Remedy: First see if the ratchet, pawl and torsion spring are intact. If they are damaged or fall off, they should be replaced. Then turn the feed screw, if the ratchet rotates and the feed shaft does not turn, it means that the steel wire pin is off and the steel wire pin is installed. complex. 7. The reason for the small rotation angle of the feed shaft is that the peach wheel and the feed cam wear badly. Remedy: Open the working gear cover and replace the new one. 8. The reason why the feeding shaft does not work is that the positioning key of the peach-shaped wheel is damaged or missing; the peach-shaped wheel is stuck with the feeding cam; the feeding cam wire pin is broken or missing. Remedy: If two cards are in phase, it is due to the wear of the shuttlecock and the peach-shaped wheel. The delivery cam or peach-shaped wheel can be removed and the working surface can be smoothed with a guillotine blade. The severe wear should be replaced. If the key or pin is damaged, replace it with a new one. 9. Reason for intermittent operation of delivery shaft: The return force of peach-shaped wheel return spring or delivery cam return spring is weak, so that peach-shaped wheel or delivery cam cannot return position. Remedy: Open the working gearbox cover, remove the two return springs and replace the new return spring. 10, positioning clutch handle stuck reason: After the separation cam wear, with the adjustment nut stuck.

Remedy: Remove the pulley assembly so that the adhesive part is disengaged, the abrasive disc is sawn with a sandpaper, and the clutch pin is replaced; the locating screw is tightened. 12. Incomplete separation of the positioning clutch Cause: Improper adjustment of the adjustment nut; slipping of the release pin and adjustment nut; wear of the positioning cam on the clutch teeth; breakage of the tension spring (positioning clutch using a fork). Inspection method: first open the positioning and separation cover, check whether the adjusting nut is in the correct position, whether the adjusting nut and the separating pin are slipped, and whether the extension spring is broken. If there is no problem and then remove the power output shaft assembly, check the technical state of the teeth embedded positioning flange. Remedy: Adjust the adjusting nut to the correct position; separate the pin or adjusting nut sliding button should be replaced; replace the tension spring; if the positioning convex edge is worn, the separating teeth can be meshed off about 0.5 mm; severe wear should be replaced.
