Disclosed is an assembly for a dosing system of a spreader machine for distributing a granular material or the like, which comprises first and second members provided with first and second openings, respectively, and an actuator connected to at least one of the first and second members and configured to provide a driving force between the first and second members, thereby, adjusting an opening size of a dosing opening provided by an overlapping area between the first and second openings, wherein the relative movement is conducted by linear movement of at least one of the first and second members.

Disclosed is a fertilization cart, including a hopper for containing the fertilizer, a first turntable, and a second turntable, where the first turntable and the second turntable are located below the hopper and arranged in correspondence with discharge openings on the hopper. Spreader openings are formed on either of the first turntable and the second turntable, and when the spreader opening is communicated with the discharge opening after rotating, a spreader channel is formed. The first turntable is capable of rotating relative to the hopper to open or close the spreader channel. The second turntable is capable of rotating relative to the first turntable to adjust the size of the spreader channel. The present disclosure is capable of solving the technical problem in the prior art that the fertilization cart cannot accurately control the amount of fertilizer for different vegetation.

Implementations disclosed herein are directed to a curved spreader disk for spreading a granular material. In some implementations, the curved spreader disc may include: a concave curved disk with a plurality of fins radiating outward from a center of the curved disk. Each of the fins may includes a substantially straight inner area near to the center of the curved disk for catching granular material and a curved outer area to accelerate movement of the granular material. The substantially straight inner area may transition the granular material from a vertical movement to a horizontal movement.

The present disclosure provides a large-scale, self-propelled nutrient spreading vehicle for efficient and precise nutrient distribution. The nutrient spreading vehicle features a drive chassis supporting an engine, wheels, and a transmission, enabling self-propelled movement. A nutrient hopper stores nutrients, while a front-mounted spreader, controlled through an in-cabin user interface, allows for adjustable discharge of the nutrients. The vehicle's conveyor system transports the nutrients from the hopper under the vehicle cabin to the front-mounted spreader. The vehicle cabin is mounted above the conveyor system, providing operators with an unobstructed view of the nutrient discharge process, thereby enhancing control and precision. Additionally, the nutrient spreading vehicle accommodates interchangeable nutrient spreaders. Control systems with adjustable parameters allow dynamic adjustment of nutrient transport and spread characteristics.

The invention relates to a fertilizer spreading machine for spreading granular fertilizer on an agricultural land, comprising: a discharge device having at least one disc arrangement which is designed to discharge fertilizer onto the agricultural land, a sensor arrangement comprising a plurality of sensors, wherein each of the plurality of sensors is designed to detect the fertilizer discharged by the discharge device by emitting detection waves in the direction of the fertilizer discharged by the discharge device and receiving detection waves reflected by the fertilizer and to provide a sensor signal dependent on the intensity of the detection waves reflected by the fertilizer, and a control device which is designed to achieve an intended fertilizer distribution on the agricultural land depending on the sensor signals provided by sensors of the sensor arrangement causes a change in the disc speed on one or more spreading discs of the disc arrangement and/or the point at which the fertilizer is delivered to one or more spreading discs of the disc arrangement.

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 automatic treatment material spreader device that is designed to automatically spread a treating material such as a salt or fertilizer for treating lawns, gardens, driveways, and parking lots. The device includes a rectangular body having a truck bed for storing treatment material, tank treads for mobility, and a funnel with rotating blades for metering and spreading the treatment material to a target area. The device is remotely controlled by an operator through a software application wherein the device can run on electrical supply provided through an internal battery. The internal batter can be charged by a wireless charging dock. The device can be programmed through the software application to spread the treatment material within a specified area and a specified treatment schedule. The device provides real time information about its location, material volume, and battery status.

A method for determining a machine- and spreading material-specific and lane-independent maximum working width, comprising throwing spreading material by means of at least one spreader disk of an agricultural spreader and detecting the thrown spreading material by means of a sensory spreading material detection system of the agricultural spreader.

A utility vehicle for dispensing fertilizer including: one or more front steering wheels; one or more rear drive wheels; a frame; a hopper to hold a dry fertilizer material; one or more hopper mounting brackets connecting the hopper to the frame, each of the one or more hopper mounting brackets including a first part and a second; where the second part connects to the first part to extend the first part of the hopper mounting bracket; where the hopper is capable of connection to the first part of the hopper mounting bracket and to the second part of the hopper mounting bracket. When the hopper is connected to the first part of the hopper mounting bracket the hopper is in a use position; while, when the hopper is connected to the second part of the hopper mounting bracket the hopper is in a calibration position.

An agricultural spreading device, with a storage container for holding a spreading material, a spreading unit for distributing the spreading material over an utilizable area, a feed chute with a chute inlet for introducing the spreading material from the storage container and a chute outlet for feeding the spreading material onto the spreading unit, wherein an additional chute is provided that is insertable into the feed chute for adjusting the chute outlet.
