Embodiment Construction
[0016] Below in conjunction with accompanying drawing and embodiment, the present invention will be further described:
[0017] Such as Figure 1-Figure 3 As shown, the parallel bar group 1 in the present invention is respectively hinged with the transplanting frame at points A, B, G, and L, and the prime mover crank GC, bar AB, bar BCD, bar EF, bar FHK 1. The crank LH constitutes the parallel rod group mechanism. The rod AB and the rod BCD are connected by a pin at point B, the crank GC of the driving part is connected with the rod BCD by a pin at C, and the rod BCD is connected with the long pin 7 at point D. Connected by pins; rod EF and rod FHK are connected by pins at point F, crank LH and rod FHK are connected by pins at H point, rod FHK is connected with long pin 7 by pins at K point, long pin 7 is connected with support Frame 2 is fixedly connected, since rod AB and rod EF, rod BCD and rod FHK, prime mover crank GC and crank LH are parallel and equal in length respect...

The invention relates to a multi-rod type transplanting mechanism of a transplanter and belongs to the field of agricultural mechanical equipment. The multi-rod type transplanting mechanism is mainly constituted by two parts, namely a parallel rod set and a duckbill component; the parallel rod set comprises a driving link crank GC, a rod piece AB, a rod piece BCD, a crank LH which is in parallel with and equal to the driving link crank GC, the rod piece AB and the rod piece BCD , a rod piece EF and a rod piece FHK, the rod pieces are connected through pins, AE, BF, GL, CH and DK are also parallel with and equal to one another and entirely form a parallel four-rod mechanism; the duckbill component is mainly composed of a left transplanting duckbill part, a right transplanting duckbill part, a linear motor, a support frame, an I-point locating pin, long pins and a connecting rod IJ. According to the multi-rod type transplanting mechanism, the transplanting duckbill parts are driven by a parallel rod set mechanism to move precisely along the predetermined tracks, cooperation between opening / closing movement of the transplanting duckbill parts and periodic motion of the parallel rod set is achieved, the mechanism has the advantages of being high in precision, good in stability, simple in structure and the like, the design target can be met well, zero-speed seedling casting is achieved, and transplanting uprightness is guaranteed.
Description
technical field [0001] The invention relates to a planting mechanism, in particular to a multi-rod planting mechanism on a transplanting machine. It belongs to the technical field of agricultural machinery equipment. Background technique [0002] At present, the transplanting of agricultural crops in my country mainly adopts the method of manual transplanting, which has many disadvantages such as low transplanting efficiency, high labor intensity, and large labor demand, and is no longer suitable for the development of agriculture today. , Semi-automatic transplanting machines have been more and more widely used in our country. [0003] The planting mechanism is an important component of the transplanting machine. According to its structure type, the automatic and semi-automatic transplanting machines being developed and used in my country can be divided into clamp-type transplanting machines, chain clamp-type transplanting machines, and seedling-guiding tube-type transplant...
