Problems solved by technology

If too much downforce is applied, especially in soft or wet soil, the soil may overcompact, which can affect the ability of germinating seeds to break through the soil
If insufficient downforce is applied, especially in hard or dry soil, the planter may lift up and out of the soil, resulting in insufficient furrow depth

Embodiment Construction

[0022] All references cited herein are hereby incorporated by reference in their entirety. In the event of a conflict between a definition in the present disclosure and a definition in a cited reference, the present disclosure controls.

[0023] This article describes an apparatus for planting seeds, such as a pneumatic seeder.

[0024] The arrangement unit of the pneumatic seeder of the prior art is shown in Fig. 1 . The sowing instrument 10 is mounted on the frame 11 via a bracket 12 . The support arm 20 is pivotally connected to the bracket 12 by a pivot 21 at a first end 20-1-1 of the support arm first portion 20-1. The support arm first part 20-1 is connected to a furrow disc 30 and a gauge wheel arm 34 at a second end 20-1-2 opposite the first end 20-1-1, for example by a shaft 32. The gauge wheel 31 is connected to a gauge wheel arm 34 opposite the shaft 32 . The second support arm part 20-2 branches from the first support arm part 20-1 and extends away from the fir...

Abstract

Described herein are air seeders that have force actuators acting on at least one of the firming implement and closing wheel to adjust for a specified downforce on at least one of the firming implement and the closing wheel. In one example, a seeding implement includes a support arm having a support arm first portion and a support arm second portion. A firming implement support arm is pivotally connected to the support arm second portion at a first pivot at a first end of the firming implement support arm. A firming implement force actuator is pivotally connected to the support arm second portion at a first end of the firming implement force actuator and connected to the firming implement support arm at the second end of the firming implement force actuator.

Description

[0001] related application [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 410,742, entitled "AIR SEEDER PRESS WHEEL AND CLOSINGWHEEL FORCE CONTROL," filed October 20, 2016. technical field [0003] Embodiments of the present disclosure relate to an instrument and application unit for seed placement by a pneumatic seeder. Background technique [0004] It has been recognized that sufficient downforce should be applied on the planter to ensure the desired furrow depth and achieve soil compaction. If too much downforce is applied, especially in soft or wet soil, the soil can become overcompacted, which can affect the ability of germinating seeds to break through the soil. If insufficient downforce is applied, especially in hard or dry soil, the planter may lift up and out of the soil, resulting in insufficient furrow depth. It is well known to apply supplemental downforce on the furrow discs of air seeders, but the furrow discs are not the...
