Rice transplanter maintenance technology

Sent to raise the back end too high

Cause: The rubber buffer is missing or damaged.

Remedy: Pick up the front end of the handle with a screwdriver and install a new bumper.

Spur tooth shaft does not turn

Cause: Sprocket ratchet wheel pin is detached; ratchet notch is worn; pawl or torsion spring falls off;

Sent to raise the back end too high

Cause: The rubber buffer is missing or damaged.

Remedy: Pick up the front end of the handle with a screwdriver and install a new bumper.

Spur tooth shaft does not turn

Cause: The delivery ratchet wheel pin fell off; the ratchet notch was worn; the pawl or torsion spring fell off; and the pinion shaft was axially swayed.

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.

Sending the shaft working angle is small

Reason: The peach-shaped wheel and the delivery cam wear badly.

Remedy: Open the working gear cover and replace the new one.

Send axis does not work

Cause: The peach-shaped wheel positioning key is damaged or missing; the peach-shaped wheel is stuck with the delivery cam; the delivery 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.

Send spindle intermittent work

Reason: The peach-shaped wheel return spring or the delivery cam return spring has a weak elasticity, so that the peach-shaped wheel or the delivery cam cannot be returned.

Remedy: Open the working gearbox cover, remove the two return springs and replace the new return spring.

Positioning clutch handle stuck

Cause: After the separation cam wears, it stagnates with the adjustment nut.

Remedy: Remove the separation cam and use a grinding wheel or file to grind the cam face into a smooth arc.

Incomplete separation of main clutch

Cause: The friction plate is stuck on the pulley; the loosening of the set screw causes the clutch pin to fall off; the clutch pin is heavily worn.

Remedy: Remove the pulley assembly, make the adhesive part off, use sandpaper to clean the friction plate saw, replace the clutch pin; tighten the set screw.

Positioning clutch is not completely separated

Cause: The adjustment nut is not properly adjusted; the release pin and the adjustment nut slide fastener; the positioning convex edge on the clutch teeth is worn; the tension spring is broken (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.

A group of planting arms does not work

Cause: The chain box drive shaft is broken; the chain is out of stock or broken.

Remedy: Attach the chain; replace the drive shaft.

Smash box

Causes: Wear of the slide block or chute; Loosening of the fixing bolts at the two ends of the sliding door; Deformation of the sliding door; Overrunning of the sliding door; Corrosion of the feeding roller; Deflection of the screw of the feeding roller.

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.

The box does not work

Cause: Finger pin or screw shaft wear; slide sleeve fixing bolt 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.

Poor or occurrence of floating seedlings

Cause: The seedling seedbed has too much or too little moisture; the depth of the seedlings is improperly adjusted; the surface of the paddy field is too soft or too soft;

Remedy: In addition to taking corresponding measures, the speed of transplanting can be slowed down, and the non-ride type transplanter can also press down the handlebar.

The number of vacant strains is more than 3-5 strains per standard.

The main reasons for the high number of culm pods are: excessive moisture on the seedbed; Corresponding measures should be taken to solve it.

After inserting the seedlings, the seedlings are scattered.

Reasons: Pusher pushes out small stroke; seedbed is too dry or moisture is too large; Miao piece and Miao piece joint are not fit tightly; paddy field top soil is too hard or too soft.

Remedy: In addition to taking relative measures, reduce the insertion speed, replace the jaws, clean or replace the guide groove.

Missing hole exceeds the standard

The rate of missed holes in mobile transplanters should not exceed 0.5%. The main reason for leaking holes is: Miao field sowing is not uniform; seedlings arched or seedlings stuck cards; take out the mouth with inclusions; seedlings disk ultra-width caused by vertical feeding difficulties.

Remedy: Re-install the seedlings or cut the seedlings into standard widths; remove debris from the seedlings; replace the seedlings with non-uniform density.

All rows of seedlings are not uniform

Reason: The water content of the bed soil is not uniform; the adjustment of each line is inconsistent; the inconsistency of the vertical feeding tension will also make the lines uneven.

Exclusion method: In addition to taking corresponding measures to solve, for some transplanters can adjust the feeding wheel one by one, so that each vertical feeding stroke is 11-12mm.

Save at the door

Causes: The claws are worn out and the seedlings cannot be fully taken; the two tips of the claws are not uniform and the jaws are too narrow or wide apart; the seedlings are too thick and the bedbed soil has a standard thickness of 2.5-3cm.

Remedy: Replace the new jaw or correct the distance between the jaws.

How much time is it?

Reason: Take loosening adjustment bolts loose; pendulum lower hole and connecting rod shaft wear.

Remedy: Re-adjust the take-off volume and tighten the adjustment bolts; replace the swing rod and connecting rod shaft.

Clip seedlings

Causes: Needle tip wear; Separation needle upturned; Platen groove deep grinding; Wear of pusher; Wear of guide bushing; Breaking of push spring; Fork and cam wear.

Remedy: Replace worn parts.

Inconsistent depth between lines

Cause: The wear of the fork, fork shaft, push cam, etc. of each planting arm is inconsistent; each chain box is not on the same level.

Remedy: Correct the chain boxes on the same level first and then replace the worn parts.

Depth adjustment failure

Cause: The sliding rod or the lifting nut produces the sliding buckle; the fixing pin hole grinds; the rectangular tube fixing pin shaft seat breaks.

Remedy: Replace lifting rods, nuts, or pins; weld fixing pins.

Separation pin touches the door

Causes: Displacement of the fontanelle; Improper installation of the planting arm; Wear of the crank arm in the planting arm; Upturning of the separation needle; Adjustment of the amount of picking up is too large; Shaking of the rocker 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 pendulum shaft or bearing shaft and bearing;
