A removable aerial application system and a method of installing the removable aerial application system in an aircraft such as a helicopter. In one embodiment, a removable aerial application system for an aircraft comprises: a tank insertable into a cabin of the aircraft; a first delivery conduit and a second delivery conduit, the first and second delivery conduits being in communication with the tank and extending aftward beneath a fuselage of the aircraft, a first auger within the first delivery conduit and a second auger within the second delivery conduit; a collector assembly defining a chamber, each of the first and second delivery conduits being in communication with the chamber; a distribution system coupled to the collector assembly; and a hydraulic system in mechanical communication with each of the first and second augers.

A device to distribute solids such as seeds, fertilizers, salts, or other granular materials through a machine for agricultural use or other similar uses, of the type that uses horizontal rotating plates or discs with spreader pallets, wherein access of the material to be distributed to the spreader pallets is tangential thereto, by use of a channeller downloaded in the central area of the disc. The device does not break the particles to be spread and, thereby, they maintain their original mass, which let us affirm that the working area is extended and the uniformity of the distribution is improved. Additionally, the tangential access of the material from the center of the rotating plate or disc, and with the same course of the pallets, gives an additional speed to the particles that allows to further increase the working area.

A dispenser unit (1) for dispensing biological material, e.g. larvae or insects etc. The dispenser unit has a rotary arrangement (2) with a drive shaft (3) and a plurality of protruding vanes (4) positioned inside a housing (10) for encasing the rotary arrangement to form chambers (5) for containing biological material between respective neighbouring vanes and an inner wall (11) of the housing. A track (6) on the housing serves to engage with each vane or movable element to control the volume of the chamber between an inlet opening (20) in a top part of the housing and an outlet opening (21) in a bottom part of the housing. This allows the biological material to be received in the chambers at the inlet opening (20) and dispensed from the chambers (5) at the outlet opening (21) during rotation of the rotary arrangement. The dispensing unit is designed to provide for an expanding chamber volume as the chambers are being rotated from the inlet opening to the outlet opening. The dispenser unit has proven to provide a low mortality e.g. for dispensing living larvae. It can be transported by a drone or the like to spread biological material over a large area.

The invention relates to a method for operating an agricultural spreader (1), comprising: providing a spreading material in a material reservoir (5) of an agricultural spreader (1); dosing the spreading material from the material reservoir (5) through a dosing opening (6); receiving the dosed spreading material by a spreader device (7); and spreading the dosed spreading material by the spreader device (7); the method further comprising: detecting digital image data by a monitoring device (4), the digital image data being indicative of a partial quantity of the spreading material located in the vicinity of the dosing opening (6) at the time of detecting the digital image data; and determining a material parameter for the partial quantity of the spreading material located in the vicinity of the dosing opening (6) from analyzing the digital image data by a control device (2). Furthermore, an arrangement for an agricultural spreader (1) system is provided.

An improved bag spreader and methods of the using the same. The bag spreader includes a bag that holds particulate material, a base removably coupled to the bag and including an exit opening to permit the particulate material to fall therethrough, an impeller below the base and configured to receive the particulate material leaving the exit opening and spread the particulate material, and a fastener circumscribing the base and securing the bag to the base. The methods include removably securing a bag to a base using a single cable tie, filling the bag with particulate material, and turning a hand crank causing the impeller to spin and spread the particulate material.

An agricultural equipment for distribution of product, such as a mixer, including a tank having at least one discharge opening, a bottom and a lateral wall, mounted on a chassis and provided with at least one discharge opening made in the lateral wall and defining a passage of rectangular shape, wherein a rotary drive mechanism that conveys the product through the opening is mounted in the tank and defines the first and second lateral rims of the opening in the direction of rotation of the mechanism. The discharge opening is provided in the region of the second lateral wall with at least one surface-occupying or volume-occupying obstructive structure that reduces the passage cross section of the opening and/or determines the geometry of this second rim at least partly.

A broadcast spreader and methods of using the same. One method includes dispersing particulate material using a broadcast spreader having a hopper and an impeller by placing the spreader in a first configuration where a first set of through openings proximate a bottom portion of the hopper permit the particulate material to pass therethrough and fall onto the impeller to thereby be distributed in a first spread pattern, and shifting the spreader into a second configuration where a second set of through openings proximate the bottom portion of the hopper permit the particulate material to pass therethrough and fall onto the impeller to thereby be distributed in a second spread pattern. The first set of through openings includes a different number of through openings than the second set of through openings, and the first spread pattern is different than the second spread pattern.

An applicator including: a frame with hopper mounted thereon to hold and dispense a granule product, the hopper including an electronically controlled gate(s); a tank to hold a liquid product; a electronically controlled spray tip(s) to dispense the liquid product; a spray pump located between the tank and spray tip(s); an operator control interface for receiving input from an operator; a control coupled to the operator control interface, the electronically controlled gate(s), and the spray tip(s), where the control receives input, dispenses the liquid or granule product based on the input received from the operator control; where when the liquid product is dispensed, the control provides a signal to the spray tip(s) to regulate a flow of the liquid product, and when the granule product is dispensed, the control provides a signal to the electronically controlled gate(s) to regulate a flow of the granule product.

Provided is a method and device for adjusting a broadcast dosage, an unmanned aerial vehicle and a storage medium. Applied to the unmanned aerial vehicle for broadcast through a material taking device driven by an electric motor, the method particularly includes: receiving a calibration instruction including a calibration rotation speed and calibration duration, controlling the electric motor to run at the calibration rotation speed within the calibration duration to discharge a material to be broadcast; acquiring a flight parameter and an actual discharge amount of the material to be broadcast discharged by the material taking device within the calibration duration; determining an adjustment coefficient between a flight speed and a rotation speed of the electric motor according to the flight parameter and the actual discharge amount; and adjusting the rotation speed of the electric motor to adjust the broadcast dosage according to the adjustment coefficient.
