Agricultural automatic planter with adjustable spacing

Abstract

The invention discloses an agricultural automatic planter with adjustable spacing. The planter comprises a trailer rack and a plurality of automatic seeding modules, wherein each automatic seeding module comprises a sliding rack and a hoeing assembly, a material storage box and a seeding assembly which are arranged on the sliding rack, each hoeing assembly includes a base, a hinge four-bar mechanism and a hoe, and each seeding assembly comprises a support frame, a material feeder, a guiding mechanism and a plurality of seeding mechanisms; each material feeder comprises two rotary blocks and asynchronization mechanism which is used for controlling the two rotary blocks to rotate synchronously and reversely, each guiding mechanism comprises an annular guide groove, each annular guide groovecomprises a horizontal guide groove part and a concave guide groove part which sinks downwards, and each seeding mechanism comprises a conveying cylinder, a slide base, a soil inlet cone and a guideplate. The manufacturing cost of the agricultural automatic planter with the adjustable spacing can be reduced, and the operational reliability of the agricultural automatic planter planter can be improved.

Description

technical field [0001] The invention relates to agricultural machinery equipment, in particular to an agricultural automatic planter with adjustable spacing. Background technique [0002] The planting of agricultural plants is generally carried out manually. With the promotion of mechanized equipment, automatic sowing equipment is widely used. For example, potatoes, peanuts, garlic, corn, beans, etc. can be sown by automatic sowing equipment. Chinese patent numbers 2012100985697, 2014105842186, and 2015204694030 all disclose related sowing equipment. In the actual use process, the biggest technical problem of the seeder is how to bury the seeds in the soil at the required depth. Although the technical solutions disclosed in the above patents can realize automatic sowing, there are problems in which the burial depth of the seeds cannot be accurately controlled, making the seeds The low survival rate leads to the problem of poor planting effect, and the sowing head is prone t...
