The correct use of wheat precision seeder

wheat precision sowing is a comprehensive technical measure to achieve high yield in high-yield plots. It has the advantages of uniform sowing, neat seedlings, strong roots, thick stems, many tillers, frost resistance, drought resistance, lodging resistance, neat heading, large ears, many grains, grain weight, and seed saving. Now the use methods and precautions of wheat precision seeder in operation are summarized as follows:

I. environmental requirements for precision seeding

1 The soil foundation is good, and precision sowing is suitable for high-yield plots with good soil, fertilizer, water and other conditions. The plots should be deeply ploughed, harrowed through, harrowed and compacted, loosened up and compacted down, flat as a mirror, no light and dark rough waste, and sufficient base fertilizer should be applied

2. The seeds selected for fine sowing of wheat with good seed quality, cleaning and grading must be varieties with good individual yield performance, strong tillering ability and high productivity per plant. Before sowing, the seeds should be cleaned with a suitable long hole sieve, and the seeds should be full and have a high germination rate. Before sowing, the seeds should be treated with drugs to prevent diseases and pests

3. The sowing time is moderate and appropriate. When precision sowing wheat, due to the small amount of sowing, it depends on Tillering to increase the population. Therefore, it must be sown in advance according to the solar terms and the air and ground temperatures. The sowing date of winter wheat is suitable for the daily average temperature of 15 ℃ -18 ℃

II. Inspection and adjustment of machines and tools before operation

1 Inspection and adjustment of seed metering device ① carefully check whether the conical hole disc used is a large hole or a small hole. The hole disc that meets the sowing rate of the wheat varieties should be used, and the large hole can meet the sowing rate requirements of 52 kg/ha --165 kg/ha, The small hole can meet the sowing rate of 37 kg/ha - 105 kg/ha. Adinareneeadler, senior director of government relations and international affairs, said: "We take these rumors seriously. ② check the gap between the conical orifice plate and the moving pair of the base of the seed metering device. The gap should be uniform and should not exceed 2 mm. If it does not match, it should be corrected and repaired. ③ check and adjust the limited number seed scraper. When people come into contact with several types of experimental machines for sowing operations, we should often check whether the seed scraper rubber plate is worn too much. If the gap size exceeds the gap size of the limited number channel plate You should turn around and use or replace with a new seed scraping rubber plate, otherwise the seed crushing rate will increase. ④ Check and adjust the seed feeder. Check whether the seed feeding wheel of the plunger type seed feeder rotates flexibly, whether the rubber ring is worn or falls off, whether the spring force of the plunger spring meets the requirements, and whether the plunger moves up and down freely. If there are defects, repair or replace them in time

2. Adjust the left and right levels to lower the seeder, so that the knife tip of the ditcher is close to the ground, and observe whether the height of the knife tip from the ground is consistent. If not, adjust the lower rod of the suspension mechanism to make the seeder left and right levels

3. Adjust the front and rear levels. When the seeder drops to the required sowing depth, observe whether the front and rear of its transmission shaft are horizontal, or whether the intermediate gearbox is horizontal. If it is not horizontal, use the upper pull rod to adjust it to the horizontal state

4. Adjustment of lifting height: the inclination angle of the transmission shaft should not exceed 25 degrees, so the lifting height should not be too large. Generally, when working in the field, it is only necessary to lift the knife tip 20 cm above the ground

5. Adjustment of sowing depth when the seeder reaches the required sowing depth, block the position adjustment handle with the positioning device to make it fall to the same depth every time

III. timely troubleshooting to ensure sowing quality

1 Plastic experimental machine is a kind of equipment used in the laboratory of plastic products factory. The reasons for missing sowing are: the sowing outlet is blocked; The seed delivery pipe is blocked; The seed metering clutch is not in the engaged position; The spring force in the seed metering reduction box is weakened or broken

2. The suppression wheel cannot rotate or block the soil. Reasons: the blade of the mud scraping angle iron is not sharp or the gap is too large; The mud scraping angle iron collides with the anti-skid gear; The soil moisture content is high

3. Reasons for the large deflection of the transmission shaft during operation: the left and right sides of the planter are not horizontal, and the unilateral limit chain of the lower link of the tractor linkage is too short

IV. precautions in operation

1 It is strictly prohibited to enter the soil first and then connect the power or sharply lower the planter to prevent damage to the tractor and the transmission parts of the planter

2. Stop working when reversing or turning

3. No one is allowed to stand on the seeder during operation to prevent accidents caused by falling under the unit

4. When replacing parts and components, the engine should be shut down
