Drum-type precision seeder

Abstract

The invention provides a drum-type precision seeder, relates to a seeding machine and in particular relates to a spaced quantitative seeding machine. The drum-type precision seeder disclosed by the invention has no harm on seeds and has few faults. The drum-type precision seeder comprises a center shaft (1) and a shaft sleeve (2), wherein the shaft sleeve is capable of rotating around the center shaft; a center chain wheel (21), a first housing (31), a cylindrical peripheral wall (33), a second housing (32) and a duckbill (4) are fixed on the shaft sleeve. The drum-type precision seeder also comprises a plurality of guide parts, a seed wheel assembly, a fixed wheel (6), a roller brush shaft (71), a roller brush shaft chain wheel (72) and a roller brush (73), wherein the roller brush shaft chain wheel is connected with the center chain wheel through a chain; a seed chamber (61) is arranged in the fixed wheel; the lower end of the sidewall of the seed chamber fits with the roller brush and a seed wheel body (51); a seed falling opening (62) is further formed in the fixed wheel; the seed wheel assembly comprises the seed wheel body (51); a plurality of indent grooves (5121) are formed in the outer peripheral wall of a wheel body part (512) of the seed wheel body at equal intervals.

Description

technical field [0001] The invention relates to a sowing machine, in particular to a machine for interval-type quantitative sowing. Background technique [0002] The hole seeder is a planting machine that sows seeds into holes according to a certain row spacing and hole spacing. At present, there is a drum-type seeding machine. Duck bills are arranged at equal intervals on the periphery of the drum, and seeds are sorted through the duck bills. For example, the application number is 200720100562.9, the authorization announcement number is CN200997763Y, and the authorization announcement date is January 2, 2008. A hand-push seeder disclosed by a Chinese utility model patent and a duckbill type precision seeding disclosed by a Chinese utility model patent with an application number of 201120288508.8, an authorized announcement number of CN202178950U, and an authorized announcement date of April 4, 2012 device. The current drum type seeder generally has the following defects: ...
