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 freedom second-order noncircular gear-Fourier gear pot seedling transplanting seedling clamping type seedling taking mechanism. The manner of soil clamping type seedling taking causes irregularity of a noncircular gear or requires an extra nose type seedling needle; amphisarca and vegetable crop allow seedlings to be taken in a clamped manner. According to the invention, a central shaft is fixed with a planet carrier; a freedom second-order center noncircular gear is loosely sleeved on the central shaft; a first intermediate shaft, a second intermediate shaft, a first planet shaft and a second planet shaft are all connected with the planet carrier through bearings; the first planet shaft and the second planet shaft are both fixed with a casing of a seedling taking claw; the freedom second-order center noncircular gear is meshed with a first freedom second-order intermediate noncircular gear and a second freedom second-order intermediate noncircular gear; a first first-order Fourier intermediate noncircular gear is meshed with a first first-order Fourier planet noncircular gear; a second first-order Fourier intermediate noncircular gear is meshed with a second first-order Fourier planet noncircular gear; the seedling taking claw forms a seedling clamping type seedling taking track. The mechanism can be implemented through the seedling taking track advantageously, and full-automatic transplanting of amphisarca and vegetables can be realized.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a seedling picking mechanism, in particular to a free second-order non-scalloped-Fourier tooth pot seedling transplanting and clipping type seedling picking mechanism. 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 clamping so...
