Seedling-taking arm of rice pot seedling transplanting machine with function of pushing seedlings

Abstract

The invention relates to a rice pot seedling transplanting machine seedling grasping arm having seedling-pushing function, which belongs to the technical field of agricultural machine. According to the invention, a cam of a seedling grasping clamp mechanism and a transition gear I of a pinion and rack mechanism are coaxially and fixedly connected to a power shaft through a connection key; a power shaft of the seedling grasping clamp mechanism is fixedly connected to the transition gear I of the pinion and rack mechanism and the cam of the seedling grasping clamp mechanism in order from inside to outside; a rear part of a cylinder tooth bar of the pinion and rack mechanism is connected to a groove of a casing end cap of the seedling grasping clamp mechanism in a movable mode; and an intermediate shaft of the pinion and rack mechanism, a pin I and a pin II are respectively and fixedly connected to a planting arm casing of the seedling grasping clamp mechanism. According to the invention, seedling push motion of slow backhaul and fast extension of a seedling pushing rod can be realized under prerequisite that normal seedling grasping and transplanting by the seedling clamp can be ensured, depth of seedling in mud can be ensured, transplanting quality is increased, the work requirement of a rotary high speed seedling separating mechanism under high speed rotation can be satisfied, and vibration impact and noise are low.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a seedling pushing mechanism of a seedling-taking arm of a high-speed rice bowl seedling transplanting machine. Background technique [0002] Rice pot seedling transplanting is a high-yield rice transplanting technology. The advanced technology is mainly reflected in: cultivation with vegetative bodies, no slow seedling stage, high survival rate, long growth period, and obvious increase in production. Through quantitative positioning of seeds, Compared with conventional sowing, it saves more than 70% of the seed cost. In addition, it can also effectively solve the problems of large seeding amount, high rate of missing seedlings, poor quality of seedlings, uneven seedling transplanting and other problems in the blanket transplanter. Compared with blanket transplanting, pot-body transplanting technology is less limited by the time of transplanting, has g...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to propose a new type of high-speed rice pot seedling transplanting machine seedling-taking arm with the function of pushing seedlings, which solves the problem in the prior art that there is no action of pushing the seedlings during the transplanting process, and ensures the depth of the transplanted seedlings into the mud
