Transplanting mechanism for forming holes in rice pot seedling film

Abstract

The invention discloses a transplanting mechanism for forming holes in rice pot seedling film, and belongs to the agricultural machinery. A planetary shaft is fixedly installed on a planetary wheel ofa non-circular gear planetary gear train mechanism, a conjugate cam is rotatably mounted on the planetary shaft, and the planetary shaft is fixedly connected with a transplanting arm housing; a leftspring clip and right spring clip are fixedly installed on two sides of the transplanting arm housing separately, and the transplanting arm housing is separately provided with a transplanting mechanism body and a film hole-forming mechanism in a matched mode, wherein the transplanting mechanism body comprises a shifting fork shaft, a transplanting shifting fork, a transplanting shifting fork chainlink, a seedling pushing rod, the left spring clip, the right spring clip, a U-shaped clamp, a seedling pushing claw and a compression spring, and a film hole-forming mechanism comprises the shiftingfork shaft, a hole-forming shifting fork, a hole-forming shifting fork chain link, a hole-forming rod, a hole-forming chain link, a hole-forming device and an extension spring. The structure of the mechanism is novel, reasonable, simple and compact, cooperation between hole forming in the film and pot seedling transplanting is good, and the mechanism has stable operation, an outstanding operationeffect and a high work efficiency.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a combined mechanism for opening holes and transplanting rice seedlings in pots. Background technique [0002] Rice film transplanting technology is a new high-efficiency and water-saving cultivation technology. It can not only increase the effective accumulated temperature, advance the growth period, effectively prevent soil erosion, but also greatly reduce the use of chemical herbicides and improve soil conditions. It is an organic The main cultivation techniques for large-scale planting and promotion of rice. Transplanting rice pot seedlings is the main agronomic method to greatly increase grain production because of its advantages of not damaging roots or slowing down seedlings during transplanting, and can greatly increase per unit yield by more than 10%. The combination of rice pot seedling transplanting and film planting technology can realize the superposition of the agrono...

Problems solved by technology

[0006] The invention adopts the method of combining the rotary non-circular gear planetary gear train mechanism with the multifunctional transplanting arm parts, and the non-uniform speed transmission of the planetary gear train controls the seedling clamping mechanism on the transplanting arm to realize the "8" figure of rice pot seedlings. Type transplanting running track, the conjugate cam and the double shift fork are used in the transplanting arm part to realize the opening and closing of the spring clip for picking seedlings and the forced seedling pushing and planting of the pushing claws, as well as the avoidance of interference and the opening of the hole mechanism. Breaking the membrane and piercing the holes achieves the purpose of synchronously completing the seedling picking, transporting, breaking the membrane and piercing the holes, and forced planting of the pot seedlings after one rotation of the rotary transplanting mechanism. The problem of poor transplanting effect has the characteristics of good compatibility between opening holes on the film and transplanting pot seedlings, novel, reasonable, compact, stable operation, small vibration, outstanding operating effect, and high operating efficiency.
