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 transplanting pit is too large, which is easy to cause floating and inverted seedlings.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing and implementation.

[0020] As shown in Figures 1 and 2, the elliptical-cylindrical gear of the walk-type rice transplanter of the present invention is inserted into the rotary sub-insertion mechanism, which includes transmission parts and planting arm parts; Drive sprocket 17 is housed on it, is connected with the center sprocket 3 that is contained in the center shaft 1 in chain wheel box 4 through chain 18, and center shaft 1 stretches out outside the left and right side axle ends of chain wheel box 4 and is respectively fixed with Left and right gear box 5 ', 5. Left and right central oval gears 14', 14 fixed on the sprocket box 4 through left and right flanges 2', 2 are respectively installed on the central shaft 1 in the left and right gear boxes 5', 5, Left and right central elliptical gears 14 ', 14 drive left and right central elliptical gears 13 ', 13 and fixed Th...

Abstract

The present invention discloses rotary separating and planting mechanism with elliptic-cylindrical 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 elliptic gears in the gear boxes drives the planetary cylindrical gear on the planetary shaft via the first intermediate elliptic gear and the second intermediate cylindrical gear. 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 triangle. The present invention can ensure high rice seedling transplanting quality.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an elliptical-cylindrical gear rear-inserting 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 ...
