Embodiment Construction

[0016] refer to figure 1 , the planting machine is shown in the form of a row crop planter 10 . The drill 10 includes an implement frame 12 that is part of a drill frame 14 . The frame includes a tongue 16 by which the planter is connected to a tractor (not shown). Three sets of ground engaging wheels support the planter frame 14 . The center set has four wheels 18 , while the left set has two wheels 20 and the right set has two wheels 22 . A plurality of planter row units 24 are mounted to the implement frame. for a given seeder. Row cells 24 are typically, but need not be, identical. exist figure 2 The row unit 24 is shown in more detail in . Row unit 24 is mounted to implement frame 12 by U-bolts 26 . The row unit 24 is provided with a central frame member 28 having a pair of upwardly extending arms 30 at its front end. Arm 30 is connected to a parallel link 31 for mounting row unit 24 to implement frame 12 for relative movement up and down between row unit 24 and...

Abstract

A seeding machine (10) is described. The seeding machine (10) is adapted to be moved over soil in a planting operation to plant seed, the machine (10) comprising: a row unit (24) having a trench opener (42), seed meter (36, 136), and a motor (66, 140) to drive the seed meter (36, 136); and a control system (80) including a seed sensor (100, 102) associated with the seed meter (36, 136). In order to minimize waste of seed during planting operation it is proposed to provide the machine (10) with a control system (80) which is adapted to operate the motor (66, 140) prior to operation of the seeding machine (10) to plant seed, to drive the seed meter (36, 136) in a priming operation to fill the seed meter (36, 136) with seed and to stop the motor (66, 140) in response to seed being detected by the associated seed sensor (100, 102) whereby when beginning a planting operation moving the seeding machine (10) over a field, seed is immediately discharged from the seed meter (36, 136).

Description

technical field [0001] The present invention relates to a seeding machine, such as a planter, and a method of operating a seeding machine. Background technique [0002] Agricultural seeders are designed to sow crops such as corn, soybeans, cotton, peanuts and other crops. Modern planters are typically 12 or more rows across width. The overall width of these planters requires that they have a flexible frame for following ground contours and folding for narrow delivery widths. Among them, the row unit on the seeder usually includes a seed meter. The seed meter performs a centering function in the precise placement of the seed in the ground. Precise and accurate seed placement is a factor in crop yield and, in turn, in farm profitability. [0003] Seed meters are usually driven by mechanical or hydro-mechanical systems and may include many complex drive chains and drive shafts to transmit power from a central power source to individual row units. The flexible and folding c...
