Combined crank rocker type transplanting mechanism

Abstract

The invention discloses a combined crank rocker type transplanting mechanism. A driving shaft is rotatably connected to a mounting plate, both a crank and a cam are fixedly connected with the drivingshaft, a cam swing link is hinged to the mounting plate, one end of a drawn wire is fixedly connected with the cam swing link, and the other end of the drawn wire is connected with a suspending cup; afirst link is hinged to the crank, both a first rocker and an intermediate connecting plate are hinged to one end of the first link, and a tail end connecting plate is hinged to the other end of thefirst link; one end of a second link is hinged to the intermediate connecting plate, the other end of the second link is hinged to the tail end connecting plate, and a second rocker is hinged to the intermediate connecting plate; and the suspending cup is connected to the tail end connecting plate through an elastic connector in a floating manner. The combined crank rocker type transplanting mechanism is simple in structure, the condition that the suspending cup is always vertical and meets the requirements on zero seedling throwing is guaranteed, and balanced inertial forces can be arranged in bilateral symmetry during operation. According to the combined crank rocker type transplanting mechanism, after the suspending cup pierces soil, the moving in a horizontal direction is little due toaction of a following device, a hole formed in a film is small, filming tearing is reduced, and the uprightness of pot seedlings is improved.

Description

Technical field: [0001] The invention relates to a compound crank rocker type transplanting mechanism. Background technique: [0002] The main dryland vegetable crops in China are still mostly cultivated by direct seeding. The amount of seeds used is large, and it is difficult to control the subsequent germination and growth of seeds. The seedlings are vulnerable to drought and flood damage in the field, and it is difficult to meet the economical requirements of planting. [0003] Seedling transplanting has the comprehensive effect of compensating the climate and advancing the growth and development period of crops. It is an inevitable trend of agricultural development to realize the mechanization of seedling raising and transplanting. At present, the eccentric wheel planting mechanism and the flat six-bar planting mechanism are more common in actual production. The track ring of the eccentric wheel planting mechanism is large in size, which will cause great damage to the pl...
