Automatic seedling transplanting depth control device

Abstract

The invention relates to an automatic seedling transplanting depth control device for a transplanter. The automatic seedling transplanting depth control device comprises a transplanter traction frame, a hydraulic control device fixedly connected to the side face of the transplanter traction frame, and a hydraulic oil cylinder arranged on the transplanter traction frame. The hydraulic control device comprises a hydraulic valve and a valve shaft connecting plate; the hydraulic valve is connected to the hydraulic oil cylinder through an oil pipe; an ejection bar of the hydraulic oil cylinder is hinged to a transplanter suspension frame; the valve shaft connecting plate is fixedly connected to a valve shaft of the hydraulic valve; one end of the valve shaft connecting plate is hinged with one end of a pulling plate; the other end of the pulling plate is hinged with one end of an oscillating bar; the other end of the oscillating bar is connected to a transplanter floating plate through a crank arm mechanism; and the middle section of the oscillating bar is provided with a rotating shaft and hinged to the side face of the transplanter traction frame through the rotating shaft. The device can detect the height variation of the ground by the transplanter floating plate and performs corresponding regulation on the height of the transplanter traction frame by pushing the hydraulic valve to work through the crank arm mechanism and the oscillating bar and controlling the lifting of the hydraulic oil cylinder through the action of the hydraulic valve, so the seedling transplanting depths are always kept consistent.

Description

technical field [0001] The invention relates to an automatic rice transplanting depth control device for a rice transplanter. Background technique [0002] The transplanting depth adjustment of the rice transplanter is usually realized by manually adjusting the height of the suspension bracket, and the height of the boat deck cannot be automatically adjusted during the working process of the rice transplanter. The phenomenon of different depths of transplanting rice seedlings, the place where the ground is raised is too deep, and the place where the ground is concave is too shallow, which affects the growth of rice seedlings. Contents of the invention [0003] The object of the present invention is to provide an automatic rice transplanting depth control device that can automatically adjust the height of the suspension bracket of the rice transplanter according to the height change of the ground, so as to keep the rice transplanting depth consistent. [0004] The technica...
