Rice transplanter

Abstract

This invention relates to a rice transplanter comprising: a transplanting frame 20 for driving rice transplanting pawls 17; and a seedling feeding member 58 connected to the transplanting frame 20 through a seedling feeding case 59. The seedling feeding member 58 has a longitudinal feed camshaft 65 formed on one side and a transverse feed threaded shaft 66 formed on the other side, and the camshaft 65 and threaded shaft 66 are arranged on the right and left sides across the center of the transplanter body, to improve two side weight balances of a transplanting portion 15 thereby keeping the transplanting precision stable. The longitudinal feed cams 116 of the longitudinal feed camshaft 65 and the slide blocks 114 of the transverse feed threaded shaft 66 are arranged on the right and left sides across the body center to facilitate their maintenances.

Description

Technical field [0001] The present invention relates to a rice transplanter equipped with a rice seedling placing platform and rice transplanting claws and capable of performing continuous rice transplanting operations. Background technique [0002] In the past, for example, in Japanese Patent Application Laid-Open No. 2000-41429, the rice seedling loading platform drive gearbox and the rice seedling feeding shaft's slider and slider support were arranged in an offset manner relative to the center of the machine body. On one side, the transplanting part becomes unbalanced in the left and right directions, which may also affect the balance of the rolling weight. [0003] Furthermore, in the case of such a structure in which the slider slides near the center of the machine body, there is a possibility that the slider or the slider support may not be maintainable due to the presence of a hook member etc. that connects the transplanting part to the main machine side. .

AI Technical Summary

Problems solved by technology

[0006] In the aforementioned Japanese Unexamined Patent Publication No. 2000-41429 or Utility Model Registration No. 2588523, etc., although there is a mechanism in which the left and right rope marks are freely undulating on the lower fulcrum of the rice transplanting drive frame supporting the hull of the rice transplanter, When adjusting the depth of rice transplanting, the lower supporting shaft is rotated to change the support height of the rice transplanter hull, the installation angle of the left and right rope marks changes at any time. The fertilization device on the rice seedling loading platform or the main machine touches and causes damage, etc.

Moreover, when the marker is kept connected to the support shaft, since the attitude of the marker is tilted forward when storing the marker, when the marker is folded from the working position to the storage position, the mud splashed by the marker may be brought to the driving operation. By

In addition, the infeed gearbox, which transmits the rotation of the drive shaft in the transverse connection pipe to the infeed shaft, is installed on the side of the rice transplanting section in an exposed state, and may be damaged due to the contact of the gearbox with obstacles in the work, etc. Gearbox etc.
