Abstract

The invention discloses a spherical grain dual-purpose type precise quantity seed sowing device. The device comprises a variable rotating speed transmission mechanism, an adjustable seed sowing innerbushing, a seed sowing device seed outlet case, a positive and negative air chamber separation cabin and a seed box retainer ring integral apparatus, wherein the variable rotating speed transmission mechanism is arranged at one end of the seed box retainer ring integral apparatus; the positive and negative air chamber separation cabin is arranged at the other end of the seed box retainer ring integral apparatus. According to the spherical grain dual-purpose type precise quantity seed sowing device, a pneumatic sleeve regulating technology is used for realizing precise quantity sowing on spherical seeds such as oilseed rapes, brassica chinensis, mung beans and soybeans with different grain diameters; through chain wheel rotation, the seed sowing device is driven to rotate; seeds are adsorbed in a negative pressure region in a seed box, are filled and are rotated to a positive pressure region for completing the seed sowing; the caliber size of a seed sucking opening can be converted by regulating the bushing, so that the seed sowing device is applicable to spherical grains with different grain diameters. An adjustable function is added on the basis of a roller type seed sowing device; one machine with multiple purposes is realized. The spherical grain dual-purpose type precise quantity seed sowing device has various advantages of practicability, convenience, wide application range, safety, reliability and the like.

Description

Technical field [0001] The invention relates to the technical field of agricultural precision seeding, in particular to a spherical grain dual-purpose precision seed metering device. Background technique [0002] Precision seeding technology is technical and large-scale planting is an important way to save costs and increase efficiency. Rape precision seeding technology is an important embodiment of small particle seeding technology. Based on this technology, small particle size precision seeding technologies such as positive and negative pressure combined seed metering device, mechanical centrifugal collecting device, air conveying type collecting device and pneumatic drum type collecting and rowing device have been developed. Promoted the development and progress of small particle seeding technology. However, special seeding equipment is required to increase seeding equipment and costs for larger and larger seeding, and it also brings certain difficulties to the promotion of p...
