The invention relates to an automatic lifting device for planting rice on a floating plate, which comprises the floating plate, three fixed pulleys, at least one sinking balancing weight and at least one suspension balancing weight with small balance weight, the three fixed pulleys are arranged at the bottom of the floating plate, and the three fixed pulleys are respectively a fixed pulley I, a fixed pulley III and a fixed pulley II; the first fixed pulley and the second fixed pulley are sequentially and evenly distributed on the axial symmetry center line of the floating plate, the lower portion of the first fixed pulley and the lower portion of the second fixed pulley are connected with at least one bottom-sinking balancing weight and at least one suspension balancing weight through flexible ropes, or the lower portion of the third fixed pulley is connected with one bottom-sinking balancing weight and one suspension balancing weight through flexible ropes so as to adapt to different water level fluctuation amplitudes. A floating effect of automatically responding to water level change can be realized by mounting a fixed pulley on the floating plate and matching with balancing weights with different weights, so that the automation degree and the stability of the system are improved; automatic adjustment is achieved through the pure mechanical principle, the structure is simple, and manufacturing cost is low.

    本发明涉及一种用于漂浮板种植水稻的自动升降装置,包括漂浮板、三个定滑轮、以及至少一个沉底配重块和至少一个小配重的悬浮配重块,其中,漂浮板底部安装有三个定滑轮,三个定滑轮分别为定滑轮一、定滑轮三、定滑轮二,并依次均匀分布在漂浮板的轴对称中心线上,定滑轮一、定滑轮二下方通过柔性绳连接至少一个沉底配重块和至少一个悬浮配重块,或在定滑轮三下方通过柔性绳连接一个沉底配重块和一个悬浮配重块,以适应不同的水位波动幅度。通过在漂浮板上安装定滑轮并配合不同重量的配重块,可以实现自动响应水位变化的漂浮效果,从而提高系统的自动化程度和稳定性;利用纯机械原理实现自动调节,结构简单,制造成本低。
