Detailed Description

The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A single-hole single-grain collection-tilting type rice precision seed-metering device is characterized in that a cross-shaped frame 5 is rotatably sleeved and mounted on a fixedly-arranged limiting control sleeve 7, a closed ring zigzag-shaped groove 6 is arranged on the outer surface of the cylinder wall of the limiting control sleeve 7 along the circumferential direction, a seed taking plate 2 with a plurality of tapered seed taking blind holes 3 is rotatably inserted into the cross-shaped frame 5, a crank shaft 8 is fixedly mounted at the inner end of the seed taking plate 2, and the inner end of the crank shaft 8 is slidably inserted into the closed ring zigzag-shaped groove 6 arranged on the limiting control sleeve 7; the seed box 4 is fixedly arranged at the upper part of the seed taking plate 2, a seed leaking hole 10 is arranged on the bottom plate of the seed box 4, a cover plate 13 with a seed dropping hole 12 is movably assembled at the lower side part of the bottom plate of the seed box 4, a push-pull plate 11 is hinged and installed on the inner side wall of the seed box 4 in a reciprocating swing mode, the lower end of the push-pull plate 11 is hinged and connected with the cover plate 13 through a connecting rod 15, a push rod 9 is movably assembled at the inner end wall of the seed box 4, the outer end of the push rod 9 is hinged and connected with the upper end of the push-pull plate 11, the inner end of the push rod 9 is in contact, pushing and matching or out of contact matching with the cross-shaped frame 5, a seed baffle plate 16 is fixedly installed at the position inside the seed box 4 and outside the push-pull plate 11, and two ends of a tension spring 14 are respectively connected with the lower side part of the push-pull plate 11 and the lower side part of the seed baffle plate 16; the seed guide pipe assembly 1 is fixedly assembled at the position below the seed taking plate 2; the seed dropping hole 12 on the cover plate 13 communicates the seed leaking hole 10 on the bottom plate of the seed box 4 with the tapered seed taking blind hole 3 on the seed taking plate 2, and the cover plate 13 blocks and communicates the seed leaking hole 10 with the tapered seed taking blind hole 3.
