摘要:
System and method for controlling the downforce applied to agricultural implement (1) with row units (10), that has a lift control device (320). The system (300) has actuators (32) which are arranged to apply force to row units (10). The actuators (32) include down chambers (33) and lift chambers (35). Each row unit (10) comprises a downpressure control device (320) in fluid communication with the down chamber (33) for controlling pressure in each down chamber (33) separately. A lift pressure control device (310) is in common fluid communication with the lift chambers (35) of all actuators (32) for controlling pressure in lift chambers (35).

A planting unit for a seeding machine having a seed meter with a metering member that moves seed sequentially along a first path to a release position at which the seed is moving in a first direction and a delivery system adapted to take seed from the metering member at the release position and control movement of the seed from the seed meter to a discharge location adjacent a seed furrow formed in soil beneath the seeding machine. The delivery system, at the release position, moves seed in a second direction along a second path. A blocking member located adjacent the first path immediately preceding the release position prevents movement of the seed in the second direction until the seed has passed the blocking member.

[Summary] [Object] There is provided a granular substance distribution device that is adapted to granular substances having various sizes and shapes and is capable of achieving high speed and highly accurate distribution of both a single granular substance at a time and plural granular substances at a time. [Organization] There are included: a rotation mechanism rotating a drive shaft; a supply-side frame body; a distribution plate provided with holders each holding a granular substance or a predetermined amount of granular substances supplied to the inside of the supply-side frame body therein in an outer circumferential portion thereof; a discharge plate provided with recessed portions each holding the granular substance or granular substances therein in an outer circumferential portion thereof in a manner to correspond to positions of the holders; a delivery plate disposed between the distribution plate and the discharge plate and having a delivery hole through which the granular substances are delivered from the distribution plate to the discharge plate formed in an upper portion thereof; and a discharge-side frame body covering the outer circumference of the discharge plate and provided with a discharge port through which the granular substance or granular substances held in each of the recessed portions is or are discharged in a lower end portion thereof, and the distribution plate and the discharge plate both rotate in the same direction and at the same speed about the drive shaft.
摘要:
A seed delivery device including a frame defining at least one seed chamber (505). The frame includes a sidewall and an air permeable floor (124). Seed can be received and deposited on the air permeable floor through an input port (503). An air input channel (501) is utilized to introduce an air stream into the seed chamber and direct it through the air permeable floor such that seed is lifted from the air permeable floor to an outlet port (22). An air bypass channel (130) is configured to separate the air stream into a first stream that is directed through the air permeable floor and a second stream that is directed through the bypass channel and recombined with the first stream, at a point prior to the output port, to prevent excess accumulation of seed in the seed chamber.

Es wird eine Vorrichtung zum Befüllen von Saatgutmagazinen (18) mit Samenkörnern ausgewählter Zuchtpflanzen beschrieben, welche Vorrichtung aus einer Einrichtung (5) zum Wiegen einer vorgegebenen Anzahl von jeweils aus den Samenkörnern einer Zuchtpflanze gebildeten Körnergruppen, aus einer an die Wiegeeinrichtung (5) angeschlossenen Einrichtung (7) zum Befüllen einer der Anzahl der Körnergruppen entsprechenden Zahl von Behältern (8) mit den einzelnen Körnergruppen und aus einer mit den Körnergruppen ausgewählter Behälter (8) beschickbaren Magazinfülleinrichtung (14) besteht. Um vorteilhafte Konstruktionsverhältnisse zu schaffen, wird vorgeschlagen, daß ein Speicher (6) für die den einzelnen Behältern (8) zugeordneten Meßwerte der Wiegeeinrichtung (5) in eine Auswerteschaltung (10) zur meßwertabhängigen Auswahl einer vorgegebenen Anzahl von Behältern (8) einlesbar ist, daß die über eine Eingabeeinheit (12) überschreibbare, mit einer Anzeige (11) verbundene Auswerteschaltung (10) eine Förderweiche (13) ansteuert, die einen die Behälter (8) in einer vorbestimmten Anordnung aufnehmenden Schrittförderer (9) einerseits mit einem Sammelbehälter (15) für die auszuscheidenden Körnergruppen und anderseits mit der Magazinfülleinrichtung (14) verbindet.
摘要:
A planting implement is disclosed which is operable for performing both row crop and drill planting operations. The implement includes a front planting structure (10) which is detachably coupled to a rear planting structure (12). The front planting structure (10) includes a front gang of planter units (16A) and the rear planting structure includes first and second gangs (16B, 16C) of planting units wherein the planting units of each gang include a furrow opener (24) and a seed metering unit (30). The planter units provide accurate seed depth control as well as singulation and precise positioning of seeds along each row. In addition, the planting implement is formed as a compact structure in a longitudinal direction to ensure that a consistent spacing between rows of seeds is provided during use of the implement.
