Description

Technical Field

[0001] The utility model relates to an independent self-adaptive electric-driven intelligent sowing negative pressure device. Background Art

[0002] In the prior art, negative pressure seeding or sowing devices use mechanical fans or hydraulic fans to generate negative pressure. The mechanical fan drives the fan to rotate through the rear output shaft and transmission shaft of the tractor, through the reduction box, and the pulley transmission, generating suction to form negative pressure in the sealing area of ​​the seed meter, and adsorbing the seeds in the seed chamber to the seeding disc.

[0003] Some use hydraulic fans, which use the tractor hydraulic system to drive the hydraulic motor, and then the hydraulic motor drives the fan through the pulley, which uses the same principle as the mechanical fan to make the seed metering device generate negative pressure to absorb the seeds. The wind pressure control mainly relies on manual adjustment of the throttle, and cannot be monitored in real time and automatically adjusted.

[0004] Seeder operation and monitoring are often cumbersome and lack remote management capabilities.

[0005] Therefore, an independent adaptive electric-driven intelligent sowing negative pressure device came into being, which can integrate human-computer interaction and remote management functions, improve the intelligence level of equipment, simplify the structure and reduce maintenance costs, thereby achieving precise sowing, energy saving and high efficiency, intelligent operation, and precise control of wind pressure.

[0007] To achieve the above-mentioned purpose, the utility model adopts electric drive technology to accurately regulate the wind pressure, ensures constant wind pressure through wind pressure sensors and intelligent closed-loop control, integrates human-computer interaction and remote management functions to improve the intelligence level of the equipment, simplifies the structure and reduces maintenance costs, thereby realizing precise sowing, energy saving and high efficiency, and intelligent operation. It is mainly composed of a control unit, a power supply unit and a negative pressure drive unit.

[0008] The power supply unit comprises a transmission mechanism and a generator (2); the transmission mechanism obtains power and drives the generator (2) to generate electricity and supply power to the negative pressure drive unit.

[0009] The negative pressure drive unit comprises a motor (7), a drive controller, a fan (6) and a wind distributor (5).

[0010] The control unit comprises a main controller and a human-computer interaction device. The signal input end of the main controller is provided with a pressure sensor (4). The pressure sensor (4) is arranged on the wind distributor (5) and monitors the wind pressure of the wind distributor (5) in real time.

[0011] A motor controller is provided at the signal output end of the main controller, and the operation of the motor (7) is controlled by the motor controller.

[0012] Furthermore, the wind distributor (5) is provided with at least two wind ducts (51), and preferably each wind duct (51) is provided with an electrically controlled damper (52) and a pressure sensor (4).

[0013] Furthermore, the above-mentioned power supply unit is also provided with a battery, which can supply power to the device more stably.

[0014] Compared with the existing technology, the utility model realizes independent and precise control of the sowing negative pressure through the power conversion and regulation link of the generator-motor driver-motor, and cooperates with the wind pressure sensor and closed-loop control system to ensure constant wind pressure and improve sowing accuracy; parameter setting, status monitoring and remote management are realized through the human-computer interaction device, which greatly improves the intelligence level and operating efficiency of the air suction seeder.
