A non-circular gear double eccentric wheel combined rice bowl seedling transplanting mechanism

Abstract

The invention discloses a non-circular gear double eccentric wheel combined rice bowl seedling transplanting mechanism. The seedling pushing angle of the existing transplanting mechanism has limitations. The central shaft of the present invention transmits power to the intermediate shaft supported on the first-stage gear box and the first-stage planetary shaft through the two-stage gear transmission mechanism; the first eccentric wheel is eccentrically fixed on the intermediate shaft, and the second eccentric wheel is eccentrically sleeved on the first-stage planet On the shaft, the two ends of the eccentric wheel connector and the cylindrical surfaces of the eccentric wheel 1 and eccentric wheel 2 respectively form a revolving pair; the secondary center non-circular gear is sleeved on the primary planetary shaft, and is embedded with the eccentric wheel 2 through teeth. The sleeve is fixed; the secondary planetary non-circular gear is fixed to the secondary planetary shaft supported on the secondary gearbox, and meshes with the secondary central non-circular gear; the end of the secondary planetary shaft protruding from the secondary gearbox is connected to the planting arm The housing is fixed. The present invention integrates the non-circular gear unequal speed transmission and the effect of the transplanting arm substantially swinging in the same direction relative to the secondary gear box, and obtains a larger seedling pushing angle as a whole.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to fully automatic transplanting of rice seedlings in pots, in particular to a non-circular gear double eccentric wheel combined rice seedling transplanting mechanism with the function of integrating picking and planting. Background technique [0002] Compared with the traditional planting mode in our country, more and more lands are now beginning to be planted in a large-scale and unified manner. Rice planting in our country needs to be combined with our country's economic and technological conditions, and take the road of standardized and low-cost development. Mechanized planting will become another dominant technology for the future development of rice planting in my country. [0003] The emergence and application of plug-in seedling transplanting technology has greatly promoted the development of planting industry. Transplanting rice seedlings can effectively increase the mul...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that most of the existing transplanting mechanisms are designed on the single-degree-of-freedom single-planetary frame structure, which has relatively large limitations, and propose a gear linkage mechanism for finding a usable and easy-to-use transplanting mechanism configuration Type synthesis, providing a non-circular gear double eccentric wheel combined pot seedling transplanting mechanism that is applied to the requirements of fully automatic rice pot seedling picking and planting, so as to obtain a more suitable motion track for rice transplanting
