Abstract There are many researches on the seed-metering device of sugarcane planter at present. However, the researches on the seed compensator device are sparse. Missing-seeding exists in the sugarcane planter, which often lead to economic loss. This paper presented a description of seed compensator device for matching with the seed-metering device. The device could solve the problem that the qualified rate was not high enough and the process of filling and clearing seeds was discontinuous. According to the analysis of the movement of seeds in the replanting process, the form of the replanting structure was determined, and the four structural parameters that affect the performance were determined: the sprocket speed, the height of the right wall of the slot, the baffle angle, and the offset distance of baffle. ADAMS was used to simulate the movement of the replanting device. And the optimal parameter values were obtained, which were 20 rpm, 24 mm, 85° and 15 mm, respectively. According to the optimal structure parameters, the experiment was carried out on the self-made experiment platform of seed compensator device. The results displayed the seed compensator device had favorable performance for seeds filling and clearing, which could realize continuous replanting for the seed-metering device and reduce missed-seeding in the process of sugarcane planting. The mean values of each index were: the empty slot rate was 1.10%, the blocking rate was 3.79%, the replanting rate was 1.29%, and the qualification rate was 96.21%. Three single-factor experiments were carried out according to the working conditions. The experiment has shown that the device was not affected by speed fluctuations. And it could meet the replanting requirements when the seeding speed was less than 17.2r/min and the number of continuous missing-seeding was less than 2.
