[0031] The rice transplanting mechanism 2 mainly includes a rice seedling box, a rice seedling separation mechanism, a rice seedling delivery mechanism, etc. The main function of the rice seedling box is to carry the rice seedlings and cooperate with the rice seedling delivery mechanism and the rice seedling separation mechanism to complete the rice seedling delivery and separation operations; the rice seedling delivery mechanism includes a longitudinal rice seedling delivery mechanism and a transverse rice seedling delivery mechanism, whose function is to deliver the rice seedlings to the rice seedling gate on time and in a quantitative manner so that the rice seedling claws can obtain the required rice seedlings each time; the rice seedling transplanting mechanism is the main working component of the rice transplanter, and is composed of a rice seedling taker and its driving mechanism and a trajectory control mechanism; under the drive of the driving mechanism and the control of the trajectory control mechanism, the rice seedling taker takes a certain number of rice seedlings according to a certain trajectory and inserts them into the soil, and then returns to the original position to start the next cycle (the specific structure and working principle are existing technologies and will not be described in detail here);

[0032] The present application integrates a furrowing mechanism into an existing rice transplanter, wherein the furrowing mechanism is arranged at the front end of the walking body 1 of the rice transplanter, so that during cultivation, furrows are opened first and then rice seedlings are transplanted, wherein the furrow opener is arranged between two adjacent rows of rice being cultivated; after the furrowing function is integrated, the weight distribution of the rice transplanter needs to be re-evaluated to ensure stability and safety during operation;
