Corn no-tillage precision planter

Abstract

The invention belongs to the field of agricultural machine, and specifically relates to a corn no-tillage precision planter. The corn no-tillage precision planter is composed of a traction frame, a machine frame, a fertilizing mechanism, a transmission mechanism, planting mechanisms, a base fertilizer box, press wheels, walking wheels, a seed opener, a land wheel, a land wheel arm, a fertilizer placer, and scribers via combination; the land wheel is arranged below the fertilizing mechanism via the land wheel arm, wherein the fertilizing mechanism is arranged on the front end of the machine frame; the land wheel is composed of a wheel disk, a steel frame, and blades; the blades are uniformly arranged on the wheel disk at a forward inclination angle of 15 DEG; the lower middle part of the front end of the machine frame is provided with a supporting leg; and the traction frame and the machine frame are arranged in a separated-type detachable manner. The corn no-tillage precision planter is simple and reasonable in structure, and is suitable for different agricultural situations; wide and narrow row spacing can be adjusted along with the topography; accurate transferring of power can be realized; transportation, hitching, and parking are convenient; and the corn no-tillage precision planter is economical applicable.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a corn no-tillage precision seeder. Background technique [0002] At present, our country is vigorously promoting the conservation tillage technology. Conservation tillage uses mechanized operations as the main means, adopts the method of less tillage or no tillage, reduces the tillage to as long as the seeds can germinate, and covers the surface with crop straw and stubble. A farming technique that mainly uses pesticides to control weeds and pests. Because this technology can reduce soil erosion, reduce dust, prevent straw burning, reduce air pollution, water storage and moisture conservation, drought resistance and water saving; fertilize soil fertility, increase soil organic matter and nitrogen and potassium content, stabilize production and increase production, reduce operating costs, save costs and increase production. Efficiency, increasing operating income, benefitin...

AI Technical Summary

Problems solved by technology

At present, there are large gaps in agronomy and rapid changes in various regions. The two-row seeder commonly used basically has no room for expansion when the total width remains unchanged. The existing seeder is far from meeting the requirements of excellent seeding quality. The main disadvantages are as follows: ①The existing driving ground wheel is set at the rear end of the fertilizer box on the frame, occupying the middle of the two seeding devices, and cannot realize the distance adjustment of the two seeding devices and thus cannot realize the wide and narrow rows. Adjustment; ②The existing driving ground wheel is a friction pair of rollers, which is easy to slip during the sowing process and the transmission is unstable, and the seeding is easy to leak holes; During the process, the drawbar is directly on the ground, and it is very difficult to connect, and other supports need to be added during transportation, which not only takes time and effort but also increases the cost; Occupies too much space and is extremely inconvenient
