Seeding machine quality appraisal

A seeder is an agricultural machine used to place seeds into the ground. According to the different types and uses of seeders, they can be divided into hand-push seeders, tractor-trailer seeders and self-propelled seeders.
seeder is widely used in planting various crops, such as wheat, corn, soybeans, cotton and other crops. Its function is to improve planting efficiency, reduce manual labor time and labor intensity, and at the same time ensure the uniformity of crop growth and stability of quality.
In the case of seeder quality appraisal, Zhongke Testing can provide seeder quality appraisal services.

1. Appearance and details: Check the appearance of the seeder for obvious signs of damage or wear. In addition, it is necessary to check whether the installation of each component is standardized and whether the coordination between various components is correct.
2. Seeding system: The seeding system is the core part of the entire seeder, including seed bank, distributor, vibrator, centrifugal disk, etc. When qualifying a planter, various parts of the seeding system need to be inspected to ensure accurate metering, arrangement and depth of seed.
3. Sowing spacing: Sowing spacing refers to the distance between seeds on the land. The seeder should be able to achieve different sowing spacing according to different crop types and planting requirements. For the quality identification of a seeder, it is necessary to check its sowing quality and effect at different spacings.
4. Sowing depth: Sowing depth refers to the depth of seeds in the soil. Different crop types and different soil types require different sowing depths. When identifying the quality of a planter, check that it can achieve the proper seeding depth for different crops and soil types.
5. Operation efficiency: The operation efficiency of a seeder is related to its seeding effect and operation speed. When conducting identification, it is necessary to check whether the operating efficiency of the seeder meets the requirements and whether it can operate stably for a long time.
6. Price: The prices of seeders with the same specifications may also be different. You need to consider whether the price of the equipment matches its performance and quality.

A company purchased three seeders from an agricultural company. Later, a dispute arose between the two parties due to property damage, and they appealed to the court because of objections to the product quality of the seeders involved.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" with the seeder involved.
identification and analysis results: The
identification and analysis expert group discussed the relevant information and on-site investigation of the seeder involved in the case and made a comprehensive quality and technical analysis, and made the following suggestions and conclusions: After the
seeder involved in the case was sown, the seed placement was uneven, with a high cavity rate and a high floating seed rate, resulting in a 5,430 fewer seedlings per mu than the normal number of seedlings in the cotton field, a decrease of 40.6%.
The seeder involved in the case has quality problems.
