Single-pressure sliding type hill-drop planter with adjustable row spacing

Abstract

The invention belongs to the technical field of design and manufacturing of agricultural machinery, and particularly relates to a single-pressure sliding type hill-drop planter with adjustable row spacing. The single-pressure sliding type hill-drop planter comprises a seed taking chuck, wherein the seed taking chuck comprises a seed taking base, a clamping rod assembly, seed taking boxes and driving core disks, and the seed taking base is provided with seed taking nests; the clamping rod assembly comprises clamped heads, torsional springs and clamping rods, and the seed taking boxes wrap the torsional springs and are connected to the seed taking base; a ratchet wheel is in a circular ring shape, a notch groove is concavely formed in the circumference of an outer ring of the ratchet wheel,and a clamping bulge adapted to a groove in a moving disc is convexly arranged on an inner ring of the ratchet wheel; the inner wall of the middle of the seed taking chuck protrudes outward to be provided with a pawl nest for placing a pawl and a flat spring nest for placing an elastic flat spring, when the ratchet wheel is arranged in an inner bore of the center of the seed taking chuck, one endof the pawl is arranged in the pawl nest, the other end of the pawl is jacked in the notch groove, and the flat spring is arranged in the flat spring nest and pressed on the pawl, thereby ensuring theeffect that the seed taking chuck stops rotating when the moving disc reverses. The single-pressure sliding type hill-drop planter with the adjustable row spacing has the advantages that not only isthe seeding precision high, but also the seeds are saved, the seeds are not selected, and the seeds are not easy to damage.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of agricultural machinery, in particular to a single-pressure-sliding hole seeder with adjustable spacing between plants. Background technique [0002] At present, with the development of agricultural diversification, especially the large-scale planting of crops such as cotton and corn, the demand for hole seeders capable of precision sowing is increasing. In the current market, the hole sowers used for sowing such crops are generally socket-type and scoop-type, but these types of hole-seeders have poor adaptability to seed size, and large species tend to lack nests, while small species The amount of seeding is large, and it is easy to waste seeds and other problems. The existing clamping hole seeders on the market have technical problems such as poor flexibility, fixed and non-adjustable plant spacing, and untreated irregular seeds are easy to get stuck in the hole seeder.
