Transplanter for maintaining constant transplanting depth

Abstract

The invention discloses a transplanter for maintaining the constant transplanting depth, which comprises a seedling table, floating bodies, a hydraulic cylinder, an electromagnetic valve, a detection floating block and a sensor, wherein the electromagnetic valve controls the hydraulic cylinder, connecting rods are fixed on the detection floating block, the front end of the detection floating block upwards tilts, the two floating bodies are provided with a fixed connecting rod, holes for the connecting rods of the detection floating block to pass are arranged on the fixed connecting rod, the detection floating block is arranged between the two floating bodies and is movably connected with the fixed connecting rod of the two floating bodies through the connecting rods so that the two floating bodies can vertically move relative to the detection floating block in the transplanting process, the sensor is vertically fixed on the fixed connecting rods of the two floating bodies, a movable rod of the sensor is in vertical contact with the detection floating block for detecting the vertically moving distance of the two floating bodies relative to the detection floating block in the transplanting process, and the sensor is electrically connected with a control circuit of the electromagnetic valve. The transplanter can maintain the constant transplanting depth and can ensure the transplanting quality.

Description

technical field [0001] The invention relates to a rice transplanting machine, in particular to a rice transplanter capable of keeping the depth of rice transplanting constant. Background technique [0002] Currently used rice transplanters, in actual production operations, because the level of the field surface, the hardness of the field mud, and the depth of the field bottom are often not constant, the depth of contact between the floating body of the rice transplanter and the field mud is also not constant, resulting in the transplanting of rice seedlings. The depth of the seedlings is not constant, and the quality of the transplanting work is low, resulting in slow growth, uneven growth rate and low yield of the seedlings. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rice transplanter capable of keeping the depth of rice transplanting constant. [0004] In order to solve the above-mentioned technical pro...
