Description

Technical Field

[0001] The utility model relates to a universal sowing detection platform for a seeder, belonging to the technical field of agricultural machinery detection auxiliary equipment. Background Art

[0002] A planter is towed by a tractor during operation. The friction generated by the rolling tires on the ground drives the seed meter, enabling precise seeding. The overall performance of a planter directly impacts seeding quality, and thus crop yield. Before shipment, planters must undergo field testing. This typically involves field-sowing a specific area. Manual statistics and calculations are then performed on data such as the number of seeds sown and spacing between seeds. This determines parameters such as the actual number of seeds planted, the number of missed seeds, and the number of reseeded seeds. This testing process requires the planter to be field-tested, which is cumbersome. After testing, the field-tested prototype must be restored to a commercially viable state, incurring significant labor and material costs. Existing planter testing typically involves sampling a proportional number of prototypes for field testing. For example, one prototype is sampled from a continuous production run of 100 plants, rather than field-testing the entire production batch. This leads to the possibility of missed inspections.

[0003] How to visually detect the sowing quality of the seed drill and realize batch, rapid and low-cost detection of the entire seed drill is a technical problem faced by technical personnel in this field. In addition, there are many types of seed drills, which are intuitively manifested in products with different numbers of rows, such as two rows, three rows, four rows, five rows, six rows, and seven rows. The corresponding seed drill tires have different left and right distances. Therefore, in order to realize rapid detection of batch simulated field sowing of the seed drill, it is also necessary to solve the problems of seed meter driving power and support of tires with different spacings.
