A pneumatic uniform fertilizer discharge device

Abstract

The invention provides a pneumatic uniform fertilizer discharge device, which includes an upper fertilizer discharge layer, a lower fertilizer discharge layer and a measurement and control system; several fertilizer discharge ports are arranged on the bottom surface of the lower fertilizer box, and the two ends are respectively arranged through the first electromagnetic valve, The first flat air inlet and the second flat air inlet connected by the second electromagnetic valve and the air guide pipe to the air compressor; the measurement and control system includes a controller and a gyroscope installed in the middle of the bottom of the lower fertilizer tank, for the gyroscope Detect the balance state of the fertilizer tiling in the lower fertilizer box in real time, and transmit the detection signal to the controller; the controller controls the first solenoid valve and the second solenoid valve to control the first tiling progress according to the signal measured by the gyroscope. The intake air volume of the air port and the second tiled air intake; the controller controls the working state of the air compressor. The invention has reasonable structural design, convenient and simple operation, not only can realize fertilizer discharge operation, but also can avoid uneven application of fertilizer, ensure uniform application of fertilizer, save resources, and reduce 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 ,crucial. 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 damag...
