Problems solved by technology

The relative movement trajectory of the claws of the rotary splitting mechanism is "waist-shaped", which is mainly used for riding rice transplanters. If it is used for walking rice transplanters, the opening of the rice transplanting hole is too large, which is easy to cause floating and inverted rice seedlings.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] As shown in Figures 1 and 2, the non-circular gear of the walk-type rice transplanter of the present invention is inserted into the rotary sub-insertion mechanism, which includes a transmission part and a planting arm part. The transmission parts include the transmission shaft 16 in the sprocket box 4 and the driving sprocket 18 mounted thereon, connected with the central sprocket 3 installed on the central shaft 1 in the sprocket case 4 through the chain 19, and the central shaft 1 extends Left and right gear boxes 5', 5 are respectively fixed on the shaft ends on the left and right sides outside the sprocket box 4. Left and right central gears 14', 14 fixed on the sprocket box 4 through left and right flanges 2', 2 are respectively housed on the central shaft 1 in the left and right gear boxes 5', 5, left and right 1, right center gear 14 ', 14 are fixed on le...

Abstract

The present invention discloses rotary separating and planting mechanism with nonknuckle gear for walking rice seedling transplanter. The central chain wheel inside the chain wheel box rotates the right and the left gear boxes separately on two ends of the central shaft, and two fixed central eccentric gears in the gear boxes drives the planetary nonknuckle gear on the planetary shaft via the meshing intermediate nonknuckle gears to rotate unevenly relatively to the gear boxes. The planting arm fixed to the end of the planetary shaft stretching beyond the gear box performs a resultant motion. The planetary gear train of the said mechanism features that the cross section centers of the central shaft, the intermediate shaft and the planetary shaft form one acute triangle. The present invention can ensure high rice seedling transplanting quality.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a non-circular gear rotary splitting mechanism of a walking rice transplanter. Background technique [0002] At present, the rice transplanter sold on the market mainly has two kinds of planting mechanisms: a crank rocker type sub-insertion mechanism and a rotary type sub-insertion mechanism. The crank-rocker type inserting mechanism can change the relative movement trajectory of the seedling claws by changing the position of the crank rotation center and the swing center of the rocker. When the relative movement trajectory is "waist-shaped", it is used for riding rice transplanters. Used for walk-behind rice transplanters when the trajectory is "dolphin-shaped". The relative movement trajectory of the claws of the rotary splitting mechanism is "waist-shaped", which is mainly used for riding rice transplanters. If it is used for walking rice transplanters, the opening of the rice transp...
