Pneumatic uniform fertilizer discharging device

Abstract

The invention provides a pneumatic uniform fertilizer discharging device, the pneumatic uniform fertilizer discharging device comprises an upper fertilizer discharging layer, a lower fertilizer discharging layer and a measurement and control system; a plurality of fertilizer discharging ports are arranged on the bottom surface of a lower fertilizer tank, the two ends of the lower fertilizer tank are respectively provided with a first flatly-spreading air inlet and a second flatly-spreading air inlet connected to an air compressor by a first electromagnetic valve, a second electromagnetic valveand an air guiding tube; the measurement and control system comprises a controller and a gyroscope installed at the middle position of the bottom of the lower fertilizer tank, the gyroscope is used for real-time detection of the flatly-spreading balance state of a fertilizer in the lower fertilizer tank and transmitting of detection signals to a controller; the controller controls the air inflowof the first flatly-spreading air inlet and the second flatly-spreading air inlet by the first electromagnetic valve and the second electromagnetic valve according to the detection signals, and the controller controls the working state of the air compressor. The pneumatic uniform fertilizer discharging device has reasonable structural design and convenient and simple operation, can realize fertilizer discharging operation, avoids the uneven application of the fertilizer, ensures the uniform application of the fertilizer, save resources and reduces the impact on natural environment.

Description

technical field [0001] The invention belongs to the field of agricultural engineering, and in particular relates to a pneumatic uniform fertilizer discharge device. Background technique [0002] The rational use and uniform application of chemical fertilizers are playing an increasingly important role in modern precision agriculture. Not only the cost of resource utilization, but also the social impact of the natural environment, so improve the efficiency and accuracy of fertilization machinery ,Significant. The traditional fertilizer applicators are all electronically controlled mechanical fertilizer discharge. The operation of mechanical parts not only has a complicated structure and consumes a lot of materials, but also tends to make the amount of fertilizer discharged from each fertilizer outlet uneven, which not only increases the cost of the fertilizer applicator itself , It may also cause uneven fertilizer discharge, and more importantly, it will cause irreversible d...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the technical problems existing in the background technology, a pneumatic uniform fertilizer discharge device proposed by the present invention uses the airflow generated by the air compressor to drive the fertilizer discharge shaft to rotate, and can also be controlled by the controller according to the balance information collected by the gyroscope. Adjust the fertilizer to be evenly spread and discharged; not only can solve the problem of poor uniformity of fertilizer discharge, but also avoid the problem of complex structure and high cost of traditional electronically controlled mechanical fertilizer discharge machines
