Problems solved by technology

The new planetary gear system rotary seedling picking mechanism includes a hybrid high-order modified elliptical gear planetary system seedling transplanting machine, a free second-order non-circular gear planetary system high-speed pot seedling transplanting mechanism and a rotary rice pot seedling transplanting mechanism. , their way of picking seedlings is the soil-clamping method, that is, the seedling needle needs to enter the pot seedling tray to pick up the seedlings, and the pot tray and root cannot be damaged, so the trajectory needs a sharp protrusion, from the seedling needle entering the pot tray to completely Leaving the pot body, the needle needs a motion trajectory close to a straight line. Due to this limitation, the irregularity of the non-circular gear is enhanced or the "protruding" needle is added, the mechanical properties of the mechanism are deteriorated, and the life is reduced; the rotary rice The pot seedling transplanting mechanism realizes a figure-eight working trajectory, considering the cooperation between the seedling picking mechanism and the seedling planting mechanism in dry land, the figure-eight trajectory is not suitable

Abstract

The invention discloses a second-order Fourier gear-eccentric non-circular gear pot seedling transplantation seedling-clamping-type seedling pick-up mechanism. The soil-clamping-type seedling pick-up can cause irregularity of the non-circular gear or increase of protruding seedling needles; and melons, fruits and vegetable crops allow the seedling-clamping-type seedling pick-up. A central shaft is fixed with a planet carrier; a second-order Fourier central non-circular gear is sheathed on the central shaft; a first intermediate shaft, a second intermediate shaft, a first planet shaft and a second planet shaft are respectively connected with a planet carrier bearing; the first planet shaft and the second planet shaft are respectively fixed with a shell of a seedling pick-up claw; the second-order Fourier central non-circular gear simultaneously meshes with a first second-order Fourier intermediate non-circular gear and a second second-order Fourier intermediate non-circular gear; a first intermediate eccentric circular gear meshes with a first planet non-circular gear, and a second intermediate eccentric circular gear meshes with a second planet non-circular gear; and a head tip of the seedling pick-up claw forms a seedling-clamping-type seedling pick-up trajectory. The seedling pick-up trajectory is beneficial to implementing the mechanism, and can implement full-automatic transplantation of the melons, fruits and vegetables.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a seedling picking mechanism, in particular to a second-order Fourier tooth-eccentric non-scalloped seedling picking mechanism for pot seedling transplanting and clamping. Background technique [0002] Mechanized transplanting is generally divided into two steps: taking seedlings and planting. According to different seedling picking methods, transplanters are divided into semi-automatic and fully automatic. The key sign is to see whether it uses mechanized seedling picking operations. [0003] The domestic automatic seedling picking mechanism has multi-rod mechanism, crank slide mechanism and incomplete gear intermittent mechanism. With the increase of transplanting frequency, the vibration of the transplanting machine will intensify, resulting in an increase in the rate of seedling injury. There are generally two ways of mechanical seedling picking: the seedling claw clampin...
