The rice transplanting machine is an essential mechanical equipment for rice planting. It can quantitatively adjust the technical indicators such as basic seedlings and planting depth, and truly realize the expansion of seedlings and shallow planting. By adjusting the horizontal and vertical seedling feeding mechanisms, the number of seedlings per hole is adjusted to 3-5 seedlings, so that the basic seedlings per mu are controlled at 50,000-80,000.

1. When crossing the ridge, pay attention that the gate of the seedlings is not collided. When crossing the canal, you must catch a wooden board and pass at a slow speed. When the car is trapped during the rice transplanting operation, do not lift the transmission parts such as the elbows and sprocket boxes at both ends of the transmission assembly, but lift the boat board or add a wooden bar between the blades of the walking ground wheel, so that the rice transplanter can climb out by itself.

2. When adjusting the amount of seedlings taken by the motorized rice transplanter, the machine must be stopped and turned off, and the main clutch must be cut off when making other adjustments, cleaning the seedling door or separating the needle.

For the paddy field of the wholesale rice transplanter, ensure that the depth of the paddy foot is moderate, not less than 10 cm and greater than 30 cm. The depth of the water should be kept at 2cm to 4cm. The vertical and horizontal slopes of the paddy field after raking should not be greater than 5 degrees to ensure that the soil in the paddy field is level and free of debris such as stones. The paddy field operated by the rice transplanter must have a certain hardness to ensure that the paddy field is settled for 12 hours, to avoid sludge blockage when the rice transplanter moves forward, which will affect the operation by the row, and it is beneficial to ensure the uprightness of the seedlings after transplanting.

When the rice transplanter is used, it also has certain requirements for raising seedlings. The thickness of the seedling bed soil suitable for the rice transplanter should be 2.0-2.5 cm, and the soil layer of the seedling bed should be as uniform as possible to ensure that there are no stones and other foreign objects in the soil layer, and the moisture should be appropriate. The seedlings should be thick and not leggy, free from diseases and insect pests, and the color should be dark green. The planted seedlings should be uniform in growth and evenly distributed to avoid the occurrence of excessive density or sparseness. Generally speaking, the seeding rate of dry seedlings per square meter is 600 grams to 700 grams, the seeding rate of germination seeds is 700 grams to 800 grams per square meter, the height of seedlings is 10 to 20 cm, and the number of leaves per seedling should not be If there are more than 5 pieces, the width of the seedling pieces should not be less than 29 cm, and the shape of the seedling pieces should be uniform and neat, without defects.

When the rice transplanter is loading the rice seedlings, it is necessary to turn up the pressure seedling rod of the rice transplanter, and move the seedling box of the rice transplanter to one side to prevent the seedling door from being blocked or missing. When using the tray to raise the seedlings, insert a seedling plug board between the tray and the seedling pieces to avoid damage to the seedlings when the rice transplanter is transplanting. After the seedling pieces are taken out, place the flat end of the transplanting board with the seedling pieces on the seedling box of the transplanter, put it into the seedling box gently, and then pull out the transplanting board. During the seedling loading process, ensure that the bottom surface of the seedling pieces is tightly attached to the bottom of the box of the rice transplanter, and the lower end is close to the seedling door.

When the remaining half of the seedling insertion process just exposed the half of the seedling feeding belt, it is necessary to add the seedlings in time. In the process of adding seedlings, ensure that the two sides of the seedlings are aligned and close to each other, and try to reduce the gap between the seedlings. During the transplanting operation, attention should be paid to ensure the integrity of the seedlings as much as possible in the process of picking and transporting, and avoid voids and yield reduction during transplanting. When installing the seedlings, ensure that the seedlings slide down smoothly, and avoid squeezing the seedlings with force, which will affect the planting quality of the seedlings.
