The reasons are: the seed box lacks seeds, the transmission mechanism does not work, and the drive wheel does not rotate due to slippage. The seeds should be filled up, and the transmission mechanism should be overhauled and adjusted to eliminate the factor of driving wheel slippage.
2. Single Manual Seeder is not seeded. The reasons are: the seeding wheel clamp and the key pin are loose and rotating, and the seed tube or seed port is blocked. The seed metering wheel should be re-fastened, and the blockage of the seed delivery or seeding port should be removed.
3. The seeding rate is uneven. The reasons are: the operating speed changes greatly, the scraper tongue is severely worn, the outer groove wheel clamp is loose, and the working range changes. Work at a constant speed, replace the scraper tongue, adjust the working length of the outer sheave, and fix the clamp.
4. The seeding depth is not enough. The reasons are: insufficient spring pressure of the opener; deformation of the opener rod makes the angle of entry into the soil smaller. Tighten the spring to increase the opener pressure; correct the opener rod to increase the soil angle.
5. High seed crushing rate. The reasons are: the operating speed is too fast, which makes the transmission speed high; the seeding device is damaged; the size and shape of the seeding wheel are not suitable; the scraping tongue is too close to the seeding wheel. Reduce the speed and work at a uniform speed, replace the metering device, use a suitable metering wheel (disk), and adjust the distance between the seed scraper tongue and the metering wheel.
6. Missing species. The reasons are: the seed tube is blocked and falls off, and the seed tube is damaged; the soil is wet and sticky, and the opener is blocked; the seeds are not clean and the Manual Seeder is blocked. It should be checked frequently to exclude; sow seeds under suitable conditions; and clean the seeds.
7. The opener is blocked. The reasons are: the planter landed too hard, the soil was too wet, and the opener was reversed after it was in the soil. Stop to clear the blockage, pay attention to suitable moisture for sowing, and prohibit backing during operation.
8. Lax soil covering. The reasons are: the angle of the covering slab is wrong, the spring pressure of the opener is insufficient, and the soil is too hard. Correctly adjust the angle of the covering slab, adjust the spring to increase the opener pressure, and increase the planter's counterweight.
9. The line spacing is inconsistent. The reasons are: the opener configuration is incorrect, and the opener fixing screws are loose. The Manual Fertilizer Seeder should be correctly configured and tightened again.
10. The adjacent line spacing is incorrect. The reasons are: the length of the marker arm is incorrect; the unit cannot walk straight. The length of the marker arm should be corrected; go straight strictly.
