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 free second-order non-circular gear-deformation ellipse gear pot seedling transplantation and clamping type seedling taking mechanism. A soil clamping type seedling taking mode causes the irregularity of a non-circular gear or the increase of a 'probing type' seedling needle; melon, fruit and vegetable crops permit a clamping type seedling taking mode. A central shaft and a planet carrier are fixedly arranged; a free second-order central non-circular gear is hollowly arranged on the central shaft in a sleeved manner; a fist middle shaft, a second middle shaft, a first planet shaft and a second planet shaft are connected with the planet carrier through a bearing; the first planet shaft and the second planet shaft are fixedly arranged on a housing provided with a seedling taking paw; the free second-order central non-circular gear is meshed with a first free second-order middle non-circular gear and a second free second-order middle non-circular gear; a first middle deformation ellipse gear and a first planet deformation ellipse gear are meshed; a second middle deformation ellipse gear and a second planet deformation ellipse gear are meshed; a sharp point of the head of the seedling taking paw is in favor of forming a clamping type seedling taking track. The seedling taking track is in favor of achievement of mechanisms, and the fully automatic transplantation of melons, fruits and vegetables can be achieved.

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-deformed elliptical tooth pot seedling transplanting clamping 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 cla...
