A sowing element for precision pneumatic seed drills. The sowing element includes a selector disc for isolating the seed, the selector disc being rotatable about an axis (X), and a conduit for transporting the seed with an initial portion which is proximal to a position for removing the seed from the selector disc and an intermediate portion which extends in continuation of the initial portion. The conduit, at least in the initial portion and in the intermediate portion, is substantially rectilinear and substantially coaxial and has an axis (Y) which is located inside a plane which is substantially perpendicular to the sowing ground and parallel with the sowing advance direction.

A sowing element for precision pneumatic seed drills. The sowing element includes a conduit for transporting the seed with an initial portion which is proximal to a device for isolating the seed, an intermediate portion which extends in continuation of the initial portion, and a terminal portion for dispensing the seed; and a pneumatic accelerator which is arranged along the conduit for transporting the seed. The pneumatic accelerator is positioned between the intermediate portion and the terminal portion of the conduit for transporting the seed.

A sensor assembly includes a sensor in the form of a microwave radar device to dispense microwaves in an area where seed or other particulate material is to be sensed. This may be a seed tube of a row unit. The microwaves of the radar provide an accurate determination if a seed or other particulate material has passed through the field of vision of the sensor to provide an accurate sensing of a seed event. This information can be used to determine the rate of planting, skips, doubles, as well as any other information related to the passing of a seed or other particulate material.

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.

A particulate material agitation control system includes a metering system and an agitation control system. The metering system includes a first meter at a first position of the metering system and a second meter at a second position of the metering system. The agitation control system an agitating system and a controller having a memory and a processor. The agitating system includes a drive system. The controller is configured to determine a first output amount of particulate material at the first position, determine a second output amount of the particulate material at the second position, determine whether a difference between the first output amount and the second output amount is greater than an output difference threshold value, and output an activation signal to the agitating system indicative of instructions to activate the drive system in response to determining that the difference between the first output amount and the second output amount is greater than the output difference threshold value.

A particle delivery assembly of an agricultural row unit includes a first particle tube and a sensor housing coupled to the first particle tube. The sensor housing is configured to receive a particle from the first particle tube and to house a sensor configured to detect the particle. The particle delivery assembly includes a second particle tube coupled to the first particle tube and to the sensor housing and configured to receive the particle from the sensor housing and to expel the particle toward a trench in soil. Additionally, the particle delivery assembly includes a coupling mechanism extending between the second particle tube and the first particle tube along the sensor housing. The coupling mechanism is configured to couple the second particle tube to the first particle tube and to at least partially secure the sensor housing between the first particle tube and the second particle tube.

A particle delivery assembly of an agricultural row unit includes a particle tube configured to receive a particle and to deliver the particle toward a trench in soil. The particle tube includes a first body portion, a second body portion, and a hinge coupled to the first body portion and to the second body portion. The hinge is configured to enable the first body portion and the second body portion to pivot relative to one another between an open position of the particle tube and a closed position of the particle tube.

A seed delivery shield, comprising a shield body comprising at least one roll pin opening configured for mounting the shield body to a row unit shank via a roll pin and at least one debris relief opening, a retention apparatus configured to attach the shield body to a row unit, and a spring plate shaped to be at least partially engaged with a rear portion of the shield body and extending rearward toward a seed delivery tube. The spring plate configured to protect the row unit and seed tube from damage during and prior to planting operations.

The invention provides a soil-opener (3) for in operation providing a functional horizontal cut at a depth from a soil surface in a functionally vertical cut into soil for providing a soil flap (16) for introducing a product into said soil, said soil-opener (3) comprising: a blade (10) having a front cutting edge (17) for cutting said functionally horizontal cut, a rear end (18), a blade width, and arranged for cutting soil functionally cross with respect to a said functionally vertical cut; a channel forming part (12) coupled to said blade (10), ending at least near said rear end (18) and adapted for providing a channel (12) allowing a said product to be introduced near said horizontal cut; a soil flap lifting part (11) adapted for lifting said soil flap (16), said soil flap lifting part (11) coupled to said blade (10), and provided between said front cutting edge (17) and said channel forming part (12); a vertical cut following part adapted for allowing said soil-opener (3) in operation to follow said functionally vertical cut, said vertical cut following part coupled to said blade (10) and extending at least to said front cutting edge (17).

The present invention discloses an opposite belt-type precise seeding device. The opposite belt-type precise seeding device comprises a seed metering tube consisting of a U-shaped shell and a cover plate, two conveying devices provided inside the seed metering tube in parallel, and a conveying plate provided at the lower end of the seed metering tube. The opposite belt-type precise seeding device belongs to the field of agricultural machinery. In a seeder, a tubular seed conveying tube is usually used for guiding movement of seeds, but the movement of the seeds in the seed conveying tube has certain randomness, so that the seed distance consistency of the seeds in a seed bed is reduced. Through control of the seeds by the conveying devices, the stable movement of the seeds is achieved and the seed distance consistency of the seeds in the seed bed is guaranteed.
