A rice transplanter row spacing adjustment mechanism

Abstract

The invention relates to a novel transplanter row spacing adjusting mechanism which comprises an installation bottom plate, wherein a power input shaft is rotationally arranged on the installation bottom plate, a guide spline is arranged at the external circumference of the output end of the power input shaft, the output end of the power input shaft is sleeved with a sleeve pipe in a sliding fit way, an internal spline which is in sliding fit with the guide spline is arranged at the internal circumference of the sleeve pipe, and the sleeving end, which is opposite to the power input shaft, of the sleeve pipe is provided with a diagonal plane; a guide column with an end part supporting against the edge of the diagonal plane of the sleeve pipe in a guiding way is vertically fixed on the installation bottom plate, the output end of the sleeve pipe is connected with a crank in a swinging way, the other end of the crank is rotationally connected with the intermediate part of a seedling claw through a pin shaft, one end of the seedling claw is rotationally connected with the rocking end of a rocking bar, the other end of the rocking bar is slidably connected with a fixed shaft, the fixed shaft is parallel to the axial direction of the power input shaft, both ends of the fixed shaft are respectively connected with a fixed shaft supporting seat and the installation bottom plate fixedly, the fixed shaft is sleeved with a compression spring, one end of the compression spring supports against the fixed shaft supporting seat positioned at one side, and the other end of the compression spring supports against the outer side of the rocking bar through a spring pressure plate.

Description

technical field [0001] The invention relates to the field of rice transplanter devices in agricultural machinery, in particular to a rice transplanter row spacing adjustment mechanism. Background technique [0002] At present, in the rice transplanter market in my country, due to the regulations of the transplanting specifications, the row spacing of the rice transplanter is generally 300mm, and the row spacing is not adjustable. For different farmland soil properties or certain crop varieties in different regions, the row spacing needs to be adjusted, and conventional rice transplanters obviously cannot meet such requirements. Therefore, in order to adjust the row spacing and improve the crop yield, it is necessary to install a row spacing adjustment mechanism on the rice transplanter. There are few existing line spacing adjustment mechanisms, and most of them are wide and narrow line spacing mechanisms, which cannot realize equal line spacing adjustment. Restricted the e...
