Free second-stage non-scalloped-eccentric non-scalloped pot seedling transplanting clamping seedling picking mechanism

Abstract

The invention discloses a free two-order non-circular gear-eccentric non-circular gear pot seedling transplanting and clamping type seedling pickling mechanism. A non-circular gear is irregular or a leading-out type seedling needle is additionally arranged can be caused by soil clamping type seedling pickling; melon, fruit and vegetable crops can be subjected to seedling clamping type seedling pickling. According to the free two-order non-circular gear-eccentric non-circular gear pot seedling transplanting and clamping type seedling pickling mechanism, a central shaft is fixedly connected with a planet carrier; the central shaft is hollowly sleeved with a free two-order central non-circular gear; a first middle shaft, a second middle shaft, a first planet shaft and a second planet shaft are connected with a planet carrier bearing; the first planet shaft and the second planet shaft are fixedly connected with a shell of a seedling pickling claw; the free two-order central non-circular gear is engaged with a first free two-order middle non-circular gear ad a second free two-order middle non-circular gear; a first middle eccentric circular gear is engaged with a first non-circular planet gear; a second middle eccentric circular gear is engaged with a second non-circular planet gear; a seedling clamping type seedling pickling track is formed by head sharp points of the seedling pickling claw. The seedling pickling track is good for achieving the mechanism and can realize the full-automatic transplanting of 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 free second-order non-scalloped-eccentric non-scalloped pot seedling transplanting clamping 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...

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
