A breakaway hinge assembly includes a first bracket coupled to a boom section, a second bracket coupled to a breakaway boom section, and a damper system. The damper system includes a first damper assembly coupled to a stop bracket of the first bracket and a second damper assembly coupled to an upper bracket arm of the first bracket. Each damper assembly includes a housing, at least one rubber element disposed within the housing, a plunger having a first end in contact with the at least one rubber element, and a stop coupled to a second end of the plunger. The first and second brackets are pivotably coupled to each other so that the breakaway boom section pivots between a first position and a second position. The damper system is configured to prevent over-pivoting and reduce impact load of the breakaway boom section when pivoting to the first and second positions.

Described herein are methods and systems for generating instructions for variable rate application of crop protection materials, comprising computing a total dosage of crop protection material(s) allowed for application in a crop field such that crop protection material(s) residue in products of crop planted in the crop field does not exceed a predefined MRL, adjusting the total dosage according to residue affecting parameters, mapping the crop field to segments according to pest distribution of one or more pests in each segment, computing a dosage of the crop protection material(s) estimated to effectively control the pest(s) in each segment based on the pest distribution in the respective segment, computing a variable rate application of the crop protection material total dosage in the crop field based on the dosage estimated for each segment, and outputting instructions to apply the crop protection material(s) in the crop field according to the variable rate application.

Providing an object detection engine, training the object detection engine to identify a weed, training the object detection engine to identify a crop, providing an image from a sensor to the object detection engine, discerning with the object detection engine the weed from the crop, and plotting a path from the weed to a spot spray assembly upon identification of the weed by the object detection engine.

An agricultural method includes providing a positive air pressure chamber to prevent outside contaminants from entering the chamber; growing crops in a plurality of cells in the chamber, each cell having multi-grow benches or levels, each cell further having connectors to vertical hoists for vertical movements in the chamber; maintaining pre-set temperature, humidity, carbon dioxide, watering and lighting levels to achieve predetermined plant growth; using motorized transport rails to deliver benches for operations including seeding, harvesting, grow media recovery, and bench wash; dispensing seeds in the cell with a mechanical seeder coupled to the transport rails; growing the crops with computer controlled nutrients, light and air level; and harvesting the crops and delivering the harvested crop at a selected outlet of the chamber.

The present invention relates to the control of harmful organisms which may appear during the cultivation of crop plants. The control is effected on the basis of the prediction of subarea-specific infestation risks.

A spraying device 1 for attachment to an elongated boom 3 present on an agricultural tractor, which extends at right angles to the direction of movement 5 of the agricultural tractor, has an elongated first blade 15, which is parallel to the boom 3. The spraying device also has a number of nozzles 19 which are connected to the first blade 15 and are oriented in a direction opposite to the direction of travel 5. Furthermore, the spraying device has an elongated second blade 25 which is also parallel to the boom 3 and which is spaced from the first blade 15. This second blade 25 is pivotable about a pivot axis 27, which is parallel to the boom 3. The second blade 25 is pivotable independently of the first blade 15 to direct the air flow 27 above the nozzles 19 so that the spray liquid completely ends up on the crop.

A deflectable touchdown wheel system for a sprayer boom of an agricultural sprayer is provided that includes a touchdown wheel that deflects transversely when contacting the ground at an angle, damping ground contact impact forces at the sprayer boom, reducing reactionary forces such as external steering inputs at the sprayer vehicle.

A kind of real-time measurement system and method for height from spray boom to crop canopy was provided in present invention patent, which includes the following steps. Step 1: Calibration for ultrasonic ranging sensor; Step 2: Determination of included angle for two ultrasonic ranging sensors; Step 3: Collection of relative height between spray boom and crop canopy; Step 4: Anti-interference processing for height data; Step 5: Calculation of relative height from spray boom to crop canopy. Its characteristic lies in: two ultrasonic ranging sensors with a certain angle are installed at each end of the spray boom, the height of crop canopy was acquired under the control of control unit, and the relative height from spray boom to crop canopy was obtained by the anti-interference analysis and data conversion, the accurate monitoring for relative height from spray boom to crop canopy was realized while the spray boom is tilted. It breaks through the technical bottleneck that the relative height of the spray boom and the crop canopy cannot be accurately obtained when the spray boom tilts due to turbulence in the field operation of the spray boom sprayer, and lays a technical foundation for the dynamic adjustment of the balance and height of the spray boom.
