Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] Such as figure 1 As shown, a rice pot seedling transplanter based on the ejector-clamping pot type includes gear transmission device I, seedling box II, horizontal seedling feeding device III, vertical seedling feeding device IV and pot seedling ejecting device V. The pot seedling ejecting device V is arranged at the bottom of the seedling box II.

[0039] Such as figure 2 As shown, the gear transmission I includes a first main shaft 1, a first sprocket 2, a second sprocket 3, a second main shaft 4, a third sprocket 5, a first oval gear 6, a first spur gear 7, a tensioning sprocket 8 , third main shaft 9 , second spur gear 12 and fourth sprocket 13 . The first main shaft 1, the second main shaft 4 and the third main shaft 9 are all supported on the frame by two sliding bearing seats; the first sprocket 2 fixed on the first main shaft 1 is dri...

Abstract

The invention discloses an ejection-pot clamping type based rice pot seedling transplanter. In the existing high-speed rice pot seedling transplanter, a transplanting arm directly clamps the pot seedling stem for transplanting and thus easily damages the seedlings. The transplanter disclosed by the invention comprises a gear transmission device, a seedling box, a transverse seedling conveying device, a longitudinal seedling conveying device and a pot seedling ejection device; in the pot seedling ejection device based on a cam swing rod, a rolling rod cam is fixed on a first main shaft, a third swing rod is fixed relative to a rack, and the rolling rod cam is connected with the third swing rod through a rolling rod; an ejector pin of an ejector pin mechanism is connected with the third swing rod through a steel wire; the bottom of the seedling box moves transversely through a slider; a wing rod shaft of the longitudinal seedling conveying device is supported on the seedling box through two shaft-end support seats and a swing rod shaft bearing seat, and the levelness of the swing rod shaft is guaranteed; and a four-rod mechanism is assembled and fixedly connected with a main chain wheel shaft and the swing rod shaft respectively through two couplings. In the invention, the ejected pot seedlings are fetched by the transplanting arm, and the clamped part is the soil block of the pot seedling, thereby avoiding seedling damage.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a rice pot seedling transplanter based on an ejection-clamping bowl type, in particular to a longitudinal seedling feeding mechanism combined with a four-bar mechanism and a chain drive and a cam-swing rod ejection mechanism. Background technique [0002] my country is the world's largest rice producer and consumer, and 90% of the world's rice is produced in Asia. my country planted rice earlier, but the mechanization level of rice planting lags far behind other developed countries. Rice is mainly planted by manual transplanting. The working conditions are difficult, it takes a lot of people, the labor intensity is high, and the work efficiency is low. [0003] At present, major universities and units in my country have successively developed high-speed rice bowl seedling transplanting machines, which have reduced labor intensity to a certain extent and improved work efficienc...
