The invention is directed broadly to an entrainment unit for distributing seed, comprising: a seed chamber for seed in bulk; a mixing chamber for mixing seed and air, the mixing chamber having an outlet for discharging entrained seeds; and an air supply unit for: (a) supplying a first air flow to the seed chamber and entraining and transporting seed to the mixing chamber, and (b) supplying a second air flow to the mixing chamber for forming a combined air flow that entrains the seed and transports the seed through the discharge outlet.

A field planting system for planting seeds of at least two plant genotypes in a field includes a multi-variety planter operable to plant the seeds of the at least two plant genotypes in the field. The field planting system also includes a controller in operable communication with the multi-variety planter. The controller is configured to receive georeferenced field information for the field and plant information for the at least two plant genotypes, and generate a planting map for the field based on the georeferenced field information and the plant information, the planting map including a planting pattern for interplanting the seeds of the at least two plant genotypes. The controller is further configured to monitor a location of the multi-variety planter in the field, and control the multi-variety planter to plant the seeds of the at least two plant genotypes in the field according to the planting map.

Device for delivering solid particles on demand, intended for agricultural machine, wherein the delivery on demand of solid particles to a receiving device is regulated, particularly in the field of technology for transporting solid granulated materials by means of an air stream, without being exclusive, in agricultural machinery when an air stream is used to transport seeds or fertilizer granules from at least one central hopper to the dosing/metering equipment located on the sowing unit, and including a source of pressurized air, a distributor of solid particles “S”, a hopper whose bottom feeds solid particles “S” to the distributor and a plate permeable to the passage of air and on which said particles “S” settle.

The present inventors have determined that implementation of an authentication process which can be selectively applied to safeguard parameters which modify dispensing of particulate material during agricultural operations can advantageously allow users of varying levels of experience and understanding to maintain ease of conducting field operations while reducing the possibility of waste and expense. A control system can determine a level of access for an operator or user on an individual basis. Upon determining a level of access for the operator to be sufficient for modifying a parameter, the control system can apply an input from the operator to modify the parameter, and can accordingly adjust dispensing of particulate material.

An air source system of an agricultural system includes a fan configured to establish an airflow along an airflow path of the air source system via rotation of the fan, and a motor assembly configured to drive the fan to rotate. The motor assembly is positioned within the airflow path of the air source system.

A biasing system for use with an associated run selector device includes a valve body member movable within a housing between opposite first and second run selection positions selecting respective first and second commodity distribution runs of the associated run selector device. The biasing system includes a first biasing element on the housing, and a second biasing element on the valve body member. The first and second biasing elements are movable relative to each other between opposite first and second biasing system positions together with the associated valve body member being moved relative to the housing between the opposite first and second run selection positions. The first and second biasing elements are mutually biased against each other to urge each other apart and towards a one or the other of the opposite first and second biasing system positions.

The present disclosure includes an agricultural system having first and second product meters configured to meter product to first and second lines, respectively. First and second motors are coupled to the first and second product meters and configured to drive them at first and second metering rates, respectively. An air source is configured to provide first and second airflows to the first and second lines, respectively. A controller electrically coupled to the first and second motors is configured to receive first and second inputs indicative of first and second numbers of first and second outlets fluidly coupled to the first and second lines, respectively. The controller is configured to instruct the first and second motors to drive the first and second product meters at the first and second metering rates, respectively, based on the first and second inputs, and to instruct the air source to provide the first and second airflows with first and second dynamic pressures or first and second velocities.

An agricultural work machine includes a frame and a tank coupled to the frame for storing a product. The tank includes a nozzle portion. A row unit is coupled to the frame and includes a hopper and a meter assembly. A product distribution line is coupled between the nozzle portion of the tank and the hopper. A blower is controlled to provide an air flow through the distribution line to transfer product from the tank to the row unit, and a mechanism located in the tank above the nozzle portion is controllable between an open position and a closed position. In the open position, the product in the tank flows through the mechanism into the nozzle portion, and in the closed position, the mechanism blocks the product in the tank from flowing into the nozzle portion.

The invention provides a pneumatic conveying system for an agricultural product applicator, which system comprises multiple fans configured to serve separate boom sections of the applicator to more efficiently conduct airflow with respect to each section. In aspects of the invention, multiple centrifugal fans of the same or similar size can be used, or multiple centrifugal fans of various sizes can be used, such as one or more larger fans and one or more smaller fans. Exemplar aspects could include three small or medium sized centrifugal fans, four small or medium sized centrifugal fans, and five small or medium sized centrifugal fans, thereby allowing the system to raise outlet air pressure at an elevated flow. Another aspect of the invention could include configuring one fan to supercharge another fan, in series, also allowing the system to raise outlet air pressure at an elevated flow.
