Semi-automatic sparsity-adjustable double-line rice transplanter

Abstract

The invention relates to a semi-automatic sparsity-adjustable double-line rice transplanter in the field of transplantation machinery. The rice transplanter comprises a power traction device, a main connecting shaft, a rack, a levelling mechanism, a power transmission mechanism and a rice placing mechanism, wherein the power traction device and the rack are connected with each other by virtue of the main connecting shaft, and the levelling mechanism is arranged in front of the rack and is connected with the rack; the rice placing mechanism is connected with the levelling mechanism by virtue of the power transmission mechanism and comprises a rice transplanting power box, a rice basket, a control rod, a starting piece and a soil covering device; the control rod is arranged on the rice basket, the starting piece is arranged on the rice transplanting power box, and the soil covering device is arranged at the bottom of the rice transplanting power box; and the rice transplanting power box comprises a first transmission gear, a main driving wheel, a motion shaft and a main kinematic chain. The semi-automatic sparsity-adjustable double-line rice transplanter provided by the invention integrates functions of levelling, ploughing, rice transplanting and soil covering, a designed mechanism is smart, a process is simple and easy to understand and grasp, and the planting distances of rice seedlings can be adjusted manually.

Description

technical field [0001] The invention relates to a device in the field of transplanting machinery, in particular to a semi-automatic rice transplanter with adjustable sparseness of two rows of seedlings. Background technique [0002] At present, the common rice transplanter is mainly composed of a power traction device, a frame, a power mechanism, a seedling claw, and a gearbox. The whole mechanical equipment is driven by the traction device, the power mechanism provides power for releasing the seedlings, and the seedling claws are responsible for placing the seedlings equidistantly. However, in such equipment, the power mechanism usually uses a motor, which increases the weight of the whole rice transplanting machine and increases the cost. Simultaneously, the action of the seedling-setting device is single, only completes the placement of the seedlings, and does not involve the digging of the soil in the early stage and the burying work in the later stage, so it is difficu...
