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...

Examples

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0029] Such as figure 1 As shown, the pneumatic uniform fertilizer discharge device of the present invention includes an upper fertilizer box 1, a lower fertilizer box 8 and a measurement and control system. The upper fertilizer box 1 is internally provided with a fertilizer discharge shaft 2 that runs through the upper fertilizer box 1. The two ends of the shaft 2 pass through the side wall of the upper fertilizer box 1;

[0030] Such as figure 2 As shown, several fertilizer outlets 13 are set on the bottom surface of the lower fertilizer box 8, and the first tiled air inlet 14 and the second tiled air inlet 15 are arranged at both ends; the first tiled air inlet 14, The second flat air inlet 15 is connected to the air compressor 17 through the first solenoid valve 20...
