The particle delivery system includes a flex system coupled to the particle belt housing proximate to the particle exit section of the particle belt, where the flex system is configured to drive each flight of the plurality of flights to temporarily flex, such that the flight drives the particle to accelerate through the particle exit section in response to straightening of the flight.

A seed meter includes a meter housing having a first chamber for seeds and a second chamber. A seed disk is rotatably supported within the meter housing and has a first side and a second side. The first side is exposed to the first chamber and the second side is exposed to the second chamber. The seed disk includes a plurality of seed openings that extend between the first and second sides at a predetermined radial position. A singulator is positioned against the first side of the seed disk and has at least one structure for removing excess seeds from the seed openings as the seed meter disk rotates relative to the singulator. A radial position of the singulator is controlled at least in part by a hub portion of the seed meter. A biasing spring is positioned to exert an axially-oriented bias force pressing the singulator against the first side of the seed meter disk.

A seeder machine (1) having at least one seeding module towed by a tractor vehicle. Each module includes an air intake (5), a hopper (7) for storing seeds (2), a rotating plate (8) provided with a plurality of holes (9) able to retain and transport a seed (2) by suction in a unitary manner, and a dosing scoop wheel (11) synchronised with the rotating plate (8), provided with a plurality of buckets (12). The dosing scoop wheel (11) has an automatic opening and closing mechanism (16) for each bucket (12), configured to cause the closing of each bucket (12) after receiving a seed (2) coming from the rotating plate (8), and to cause the opening thereof when the respective bucket (12) adopts an inverted position, wherein the seed (2) is able to fall from a point adjacent to the level of the terrain.

A planting implement including a toolbar and a seed metering system supported by the toolbar. The seed metering system includes at least one row unit. Each row unit includes a frame, an auxiliary seed hopper supported by the frame, a seed meter fluidly coupled to the auxiliary seed hopper, and a vacuum fan fluidly coupled to the auxiliary seed hopper and the seed meter in a closed fluid system in which the vacuum fan recirculates air through the auxiliary seed hopper and the seed meter.

An agricultural machine includes a seeding system comprising a plurality of planting units, each planting unit configured to meter and deliver seed and a control system configured to obtain a seed planting model that identifies a plurality of seed planting locations on a worksite, identify a machine path on the worksite, identify, based on the machine path, a set of the seed planting locations for each of the planting units, and control each planting unit to deliver seeds to the set of seed planting locations identified for the planting unit.

The seeding positioner device applied to agricultural planters comprising a structure consisted of a rotating seed pusher that directs the seeds to a labyrinth (14) moving in a opposite direction, allowing to control the seed release as the speed the assembly rotates, so that the discharge spacing will be commanded by a gears-driven compartment (22) which directs the seeds to a discharge tube (23), wherein the pneumatic system generates positive air pressure. Thus, the compressed air will push the seed against the soil in order to maintain the perfect line positioning and increasing the planting speed. The seeding positioner device can be driven by an electric motor, a pneumatic motor, a hydraulic motor, a cardan shaft, a pitch chain, or a twisting cable, according to the planter type. In addition, the device constructional shape prevents the seeds from being damaged and loses germination capacity when passing through the mechanism, allowing the equipment to be applied and adapted to work with any seed type.

Disclosed herein are various adjustable seed meter embodiments having a first seed disk having first openings defined therein and a second seed disk having second openings defined therein adjacent to the first openings such that the first and second openings are alignable to form adjustable seed cells. Various embodiments have a plate adjustment drive system to rotate the first and second seed disks in relation to each other. Other embodiments relate to methods of automatically adjusting a seed meter during operation of the overall planting system.

A seed meter includes a meter housing having a first chamber for seeds and a second chamber. A seed disk is rotatably supported within the meter housing and has a first side and a second side. The first side is exposed to the first chamber and the second side is exposed to the second chamber. The seed disk includes a plurality of seed openings that extend between the first and second sides at a predetermined radial position. A singulator is positioned against the first side of the seed disk and has at least one structure for removing excess seeds from the seed openings as the seed meter disk rotates relative to the singulator. A radial position of the singulator is controlled at least in part by a hub portion of the seed meter. A biasing spring is positioned to exert an axially-oriented bias force pressing the singulator against the first side of the seed meter disk.

In one aspect, a calibration method for a seed meter may include controlling an operation of a singulator to apply an initial aggressiveness setting for the singulator. The method may further include controlling the seed meter to rotate a seed transport member of the seed meter relative to a seed chamber of the seed meter containing a plurality of seeds. The method may additionally include performing a calibration cycle, which may include monitoring a first parameter indicative of a number of occurrences of seed multiples as the seed transport member rotates, iteratively adjusting the aggressiveness setting from the initial aggressiveness setting as the first parameter is being monitored, and when the first parameter crosses a first threshold, recording the associated aggressiveness setting as a minimum aggressiveness setting for the singulator.

A seed metering system for metering a plurality of seeds includes a meter housing having a first side and a second side. A seed inlet is positioned at the first side and an aperture is positioned at the second side. The seed metering system further includes a hub mounted within the aperture, a retaining member located at the hub, and a metering member positioned on the hub. The metering member compressively engages the retaining member.
