Definitions

• the present invention relates to an automation and flow control system for agricultural input dispensing equipment such as seeds and fertilizers.
• Said system provides a controller device that controls the opening and closing of the rear gate, the speed of the rotating belt and the rotation speed of the distribution discs of these types of distributing equipment.
• This machine configuration has a number of technical and functional drawbacks as it is necessary to stop the machine every time the flow of the distributed inputs needs to be changed; This procedure reflects the work performance, the machine efficiency, leading to lost productivity, very poor precision related to the dispensing spread over the dispensing area, etc.
• the applicant of this report has filed another previous patent application, filed under number PI1015607-0, where he describes as a solution an automated gate opening and closing system for input distribution equipment. It is also connected to the conveyor belt and distribution discs, where through a specific software controller it receives information regarding the prescription of the mapped area and the positioning of the equipment, and activates the opening and closing of the gate, as well as adjusts the speed of rotation of the gate. belt and distribution discs based on the predetermined input flow in the system itself.
• the system object of the present patent application, consists in the adjustment and refinements of that system already developed, object of the aforementioned patent of the same applicant. These improvements are the result of the commercial success of this already developed system, which identified some complementary technical details that resulted in a new system for flow control. This system guarantees a higher performance, in the sense of control, productivity and precision of the equipment in relation to the distribution of the inputs.
• the system which is the subject of this report is comprised of a software-specific control device connected to the mechanisms for driving the sluice gate, distribution discs and the conveyor belt of seed, fertilizer or similar products;
• This system also communicates with equipment positioning device and mapped area prescription, and aims to automate all operation related to the control of seed flow through the automation of the opening and closing of the gate of the distributing equipment, as well as the control of the speed of the conveyor and the distribution discs of the equipment.
• This system is implemented in the machine and provides electronic control device and drive mechanisms coupled to the gate opening and closing mechanism, to the belt rotation mechanism and can be connected to the distribution discs drive mechanism of the distributing equipment. seed and fertilizer; Said system also communicates with the equipment positioning system and prescription of the area to be distributed the inputs.
• the system is characterized by the fact that it receives the information regarding the prescription of the mapped area with the positioning and the displacement speed of the equipment, the speed and the necessary seed flow in the exact positioning area of the equipment and from these variables. instantly calculate belt rotation speed, gate opening, and the relationship between belt rotation speed; and this calculation obeys an optimal function where the gate opening should be as small as possible for the highest possible belt rotation speed, for that input flow related to the equipment speed.
• An electronic device is coupled to the equipment to process information and control these drives.
• This system is also advantageous for its use at fixed rate distribution regardless of application map, as it is possible to increase distribution productivity due to the possibility of speeding up the applicator equipment, in this case. rotating conveyor, regardless of the terrain to be explored.
• Another advantage of the system refers to the amplitude variation in the input flow rate in a single application for a prescription map, since the system calculation is performed on time, where the flow rate, ie the dose to be distributed, it can be changed automatically punctually along the prescribed map, not requiring a transfer of the equipment in the same place to replace missing inputs.
