First, seedlings and paddy fields in line with agronomic requirements is very important
High-performance transplanters, such as the Yangma VP6 and the Kubota NSPU68CM, have the agronomic characteristics of "fixed point, fixed seedling, wide row and shallow planting", which is conducive to tapping the potential of rice yield. But no matter what kind of transplanter, seedlings and paddy fields must meet the agronomic requirements, otherwise, will lead to transplanting failure.
Mechanical transplanting seedlings generally require soil thickness of 2 ~ 2.5cm, seedling height of 12 ~ 17cm, seedling age of 15 ~ 20 days, leaf age of 3.5 ~ 4 leaves, for soil medium small seedlings. It is required that the root system is developed, the root force is strong, the soil is not spassive, and it can be integrated into the seedling box. Special attention should be paid to the density, width and thickness of seedlings must be standardized.
Paddy field general requirements, rotation tillage depth of 10 ~ 15cm; Field surface level, no residue; Water layer 1 ~ 2cm; The field should be firm, 1 day for sandy soil, 2 ~ 3 days for loamy soil, and 3 ~ 4 days for clay.
Two, do a good job of transplanter inspection and test operation
In order to make the transplanter run normally and bring benefits into play, it is necessary to check and test it first, so as to find problems in time and solve problems in time. Inspection requirements, first to check and adjust the transmission parts and transmission fasteners, insert arms and other moving parts; Two to check and adjust the needle, fork, box, rail, rail door and other components and components clearance; Three to check and adjust the pull line; Four to check and adjust the position of the planting arm; Five to check engine fuel and oil, gearbox oil, rotation and friction parts of the lubricating oil. Test operation requirements, one is to place the rice transplanter joystick in the "neutral" position before starting the engine; The second is to check and adjust the hydraulic lifting mechanism and hydraulic profile system; Three is to check and adjust the clutch handle; Four is to check and adjust the planting arm, seedling box working conditions; Fifth, check and adjust the number of seedlings taken vertically, the number of seedlings taken horizontally and the spacing between plants; Six is to check and adjust the transmission gear, left and right steering mechanism.
Three, transplanter transport is exquisite, in and out of paddy fields to adapt to local conditions
Transplanter transport to the operation site is exquisite, in general, short distance transport, can be directly opened to the edge of the field; Long distance transport, to choose the appropriate means of transport transport, the length, width, strength of the springboard must meet the technical requirements, transplanter should be fixed solid. The transplanter enters and leaves the paddy field according to local conditions. When the gap between paddy field and road surface is small, the transplanter's planting part enters and leaves the paddy field in a straight, vertical and slow way under the lifting state. For the large drop between the paddy field and the road surface, when entering the field, lift the planting part and drive into the paddy field at low speed. When out of the field, be sure to back up to the road.
At the same time, must choose the appropriate planting driving route. Planting driving has a variety of routes, general requirements, the field at both ends of the turn to leave two working width of the room, the first directly on the ridge transplanting, and then back and forth planting, the penultimate non full width operation, by reducing the number of rows to make the last full width planting, after the two ends of the insertion, driving out of the field (and wheat machine strip sowing similar).
Four, loaded seedling and seedling supply to standardize
1. When loading rice seedlings for the first time, be sure to move the seedling box to the most left or right before loading rice seedlings.
2. Seedling block placed on the seedling box should be flat, the bottom close to the seedling box. After the seedling block is placed, the seedling press is pressed down. Press the seedling to the degree that the seedling block can slide on the seedling box, but not jump up and down.
3. Seedlings should be supplied before they reach the seedling supply position. When replenishing seedlings, pay attention to the end face of the remaining seedling block and the end face of the replenished seedling block.
4. When each row in the seedling box has seedlings, it is not necessary to supply seedlings to move the seedling box to the left (right) side.
5. If there is no seedlings on one of the seedling boxes in the operation, seedlings should be resupplied according to the requirements of the first seedling loading.
Five, do a good job of plant distance, take seedling amount, insert deep three adjustments
1. Adjust the appropriate plant spacing. At present, the row spacing of the existing mature transplanter is fixed at 30cm, which is a scientific conclusion obtained through long-term experiments. There is no need to worry about too wide row spacing. Before planting, according to agronomic requirements, adjust to the required plant spacing, the general requirement is 12cm, mu hole number reaches 18,000. Plant spacing must be adjusted in place at low speed. Note that it is strictly prohibited to use walking gear planting.
2. Adjust the amount of rice seedlings taken. The adjustment of seedling quantity should ensure that 3~5 plants are planted in each hole, and beware of too much or too little.
3. Adjust the depth of transplanting. Before transplanting, according to agronomic requirements, the insertion depth is preset first, and after a trial insertion in the field, the insertion depth is adjusted according to the field situation. Insert deep adjustment must grasp "not not drift, the shallower the better" principle. If in order to look good, the seedling inserted deep, resulting in "fixed core" seedling, machine transplanting is no advantage at all, even failure.
Six, seedling transplanting operation matters needing attention
1. The first trip is the benchmark for transplanting seedlings, and the transplanting linearity should be maintained.
2. If the transplanting arm stops working and gives out abnormal sound, the main clutch should be cut off quickly, the engine should be put out, the cause of the fault should be confirmed, and the fault should be eliminated in time.
3. When turning in the field, stop the work of the planting parts and lift the planting parts. It is forbidden to transplanting rice while turning.
4. When crossing the ditch and ridge, the planting part should be raised and run slowly in a straight and vertical line.
5. When the transplanter is driving and operating on the road, attention should be paid to the protection of the left and right sides of the guide rail, to prevent collision and damage, and to recover the printer in time.
6. Do not take off the handle of the main clutch when driving downhill.
Seven, the maintenance technology of transplanter
1. The daily maintenance of rice transplanter is to wash with water immediately after the end of the operation, and pay attention to avoid water entering the air filter. Wheels and other rotating parts such as debris should be removed; Second, timely inspection of all parts, found that the problem is solved immediately; The third is to fill or supplement fuel oil and lubricating oil.
2. The replacement of engine oil for the power of the transplanter, whether it is gasoline engine or diesel engine, after a certain time of run-in (various models of run-in period), to change the oil in time, according to the provisions of every certain time to replace. The type and number of oil, the amount of filling, how to replace, etc., must be in accordance with the requirements of the instruction manual.
3. Maintenance of carburetor when the transplanter is not used for a long time, be sure to drain the gasoline in the carburetor. Otherwise, the engine may not work the next time it is used.
4. Gearbox gear oil replacement gearbox gear oil has two functions: one is normal lubrication; The second is the role of hydraulic oil. After a certain time to run in, to replace in time, according to the provisions, every certain time to replace.
5. The maintenance of the interplanting arm is an important working part of the transplanter. Every day, it is necessary to check whether the interplanting arm is short of oil, and the mixture of butter and gear oil should be supplemented at a ratio of 1:1. After the planting operation is stopped, the insertion fork should be placed in the bottom position to extend the service life of the insertion arm pressure spring.
6 battery maintenance battery is not used, every certain time to replenish the battery, to prevent long-term power loss. It is recommended to remove the pile head wire, first remove the negative pole, then remove the positive pole; When installing, connect the positive pole first and then the negative pole.
7. The insertion part should be put to the end. The insertion part should not hover in the air for a long time, otherwise it is easy to cause damage to the hydraulic system.
8. When the transplanter is not in use, the hydraulic locking device must be opened to make it in the unlocked state.
