Conjugate cam, crank and rocker rod combined flower-plant transplanting mechanism and designing method thereof

Abstract

The invention discloses a conjugate cam, crank and rocker rod combined flower-plant transplanting mechanism and a designing method thereof. A planet gear system transplanting mechanism is limited in realizing track flexibility, and a rod mechanism with double stirrup tracks is difficult in parameter designing and adjusting. The conjugate cam, crank and rocker rod combined flower-plant transplanting mechanism is characterized in that one ends of a first conjugate cam, a second conjugate cam and a crank are all hinged to a rack through a cam shaft, the other end of the crank is hinged to the middle of a second connecting rod, a first cam swing rod, a second cam swing rod and a swing rod are fixedly connected, the first cam swing rod is connected with the first conjugate cam through a first roller, the second cam swing rod is connected with the second conjugate cam through a second roller, and the swing rod is hinged to the second connecting rod through a first connecting rod. The designing method includes: reversely solving the conjugate cams through a mathematic model of single stirrup tracks formed by an end point of the free end of the second connecting rod, coordinates of a hinged point of a fork-shaped swing rod and the rack and known rod length conditions. The single stirrup tracks are realized by changing profile of the conjugate cams to control movement laws of a rocker rod, and the conjugate cam, crank and rocker rod combined flower-plant transplanting mechanism is simple.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a flower transplanting method, in particular to a conjugate cam crank rocker combined flower transplanting mechanism and a design method thereof. Background technique [0002] Flower transplanting technology can reduce the growth cycle of crops, maintain the uniform quality of crops, and achieve the purpose of increasing production and income. It has become the main planting measure in the production of modern greenhouse potted flowers. The development of automatic potted flower transplanting technology is an important measure to comply with the high growth rate of potted flower production, solve the existing low productivity and promote the modernization of agriculture in our country. With the development of flower production and facility agriculture technology in our country, the foundation and conditions for vigorously developing automatic potted flower transplanting technol...

Problems solved by technology

[0003] The existing single-degree-of-freedom intermittent gear planetary gear train and continuous non-circular gear planetary gear train transplanting mechanism are limited by the gear transmission ratio, which can realize the flexibility of the trajectory. The design of the seedling planting mechanism in the flower tray is very difficult; although the hybrid drive mechanism has two degrees of freedom, the trajectory design is flexible, but the control system of the machine is not easy to design
