Noncircular-bevel gear double-planet-carrier cam combined type transplanting mechanism for vegetable pot seedlings

Abstract

The invention discloses a noncircular-bevel gear double-planet-carrier cam combined type transplanting mechanism for vegetable pot seedlings. Existing transplanting devices cannot deeply clamp soil and take seedlings due to limitation of seedling taking trajectory. Two primary planet noncircular gear systems are arranged at two ends of a central shaft symmetrically. Two ends of each primary planet noncircular gear system are connected with a secondary upper planet bevel gear system and a secondary lower planet bevel gear system respectively. Upper transplanting arms are fixed to the secondary upper planet bevel gear systems, and lower transplanting arms are fixed to the secondary lower planet bevel gear systems. Each primary planet noncircular gear system comprises a primary gear box, a primary central noncircular gear, a primary lower planet shaft, a primary lower planet noncircular gear, a lower cam connecting rod, a cam bawl, a cam, an upper cam connecting rod, a primary upper planet noncircular gear and a primary upper planet shaft. The noncircular-bevel gear double-planet-carrier cam combined type transplanting mechanism has the advantages that cam mechanisms drive secondary planet carriers to swing, about-4cm seedling taking trajectory at a trajectory seedling taking position is achieved, collision between transplanters and the seedlings is avoided, and soil clamping and seedling taking deep in pot slots are realized.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a non-circular-bevel gear double planetary frame cam combined transplanting mechanism which is suitable for automatic vegetable pot seedling transplanting and has the characteristics of integrated picking and planting. Background technique [0002] my country is the largest vegetable producer and consumer in the world, and its vegetable production accounts for about 60% of the world's total. Vegetable production has always been a labor-intensive industry, and labor costs account for more than 50% of vegetable production costs. With the continuous development of today's economy, more labor will shift from planting to other industries, and rural labor will transfer to cities or other industries. The developed areas of the country will cause a shortage of rural labor, so the realization of mechanization and automation of vegetable transplanting operations to solve su...
