Embodiment 1

[0035] Such as Figure 1 ~ Figure 3 As shown, the present embodiment provides a liquid fertilizer flow regulating device, which includes a flow regulating valve 1, a first gear 2, a second gear 3, a steering gear 4 and a steering gear controller 5, and the flow regulating valve 1 is fixed on On the front side of steering gear 4.

[0036] In order to fix the flow regulating valve 1 on the steering gear 4 and ensure the stable operation of the flow regulating valve 1, the flow regulating device of this embodiment also includes a U-shaped fixing frame 6, the U-shaped fixing frame 6 has two cantilevers and connects two The horizontal arm of the bar cantilever, the steering gear 4 is fixedly installed in the groove of the U-shaped fixing frame 6, and the left side, the right side and the rear side of the steering gear 4 are respectively connected with the two cantilevers and the horizontal side of the U-shaped fixing bracket 6. The inner sides of the arms are connected, and the fl...

Embodiment 2

[0048] The main features of this embodiment are: the flow regulating valve 1 can also be fixed on the rear side, left side or right side of the steering gear 4, when the flow regulating valve 1 is fixed on the rear side of the steering gear 4, the steering gear The left side, the right side and the front side of the steering gear 4 are respectively connected with the two cantilever arms of the U-shaped fixed frame 6 and the inner side of the horizontal arm. When the flow regulating valve 1 is fixed on the left side of the steering gear 4, the steering gear The right side, the front side and the back side of 4 are respectively connected with the inner sides of the two cantilever arms of the U-shaped fixed frame 6 and the horizontal arm. When the flow regulating valve 1 is fixed on the right side of the steering gear 4, the steering gear 4 The left side, the front side and the rear side are connected with the inner sides of the two cantilever arms of the U-shaped fixed frame 6 an...

Embodiment 3

[0050] The main feature of this embodiment is that the diameters of the inlet 1031 and the outlet 1033 can be 4mm, 12mm, etc. All the other are with embodiment 1.

[0051] In summary, the flow regulating device of the present invention controls the rotation of the steering gear through the steering gear controller, and the steering gear drives the spool of the flow regulating valve to rotate through two meshing gears to change the flow through the flow regulating valve to realize liquid fertilizer. The precise adjustment function of liquid fertilizer flow at low flow rate realizes the real-time adjustment of liquid fertilizer flow rate for crops, maximizes the utilization rate of fertilizer, reduces waste of fertilizer and environmental pollution, and has a simple structure and low power consumption. , high reliability and low production cost.

Abstract

The invention discloses a liquid fertilizer flow regulation device, a fertilization system and a method. The device includes a flow regulating valve, a first gear, a second gear, a steering engine anda steering engine controller. The flow regulating valve is fixed on a side of the steering engine, the first gear is fixed on an output shaft of the steering engine, the second gear is fixed at the upper end of the valve core in the flow regulating valve, the first gear and the second gear are engaged, and the steering engine controller is connected to the steering engine. The liquid fertilizer flow regulation device provided by the invention realizes liquid fertilizer flow regulation under a low flow of liquid fertilization at a variable rate, realizes precise fertilization to crops, improves the fertilizer utilization rate, reduces fertilizer wasting and environmental pollution, and at the same time has the advantages of simple structure, low power consumption and low production cost.

Description

technical field [0001] The invention relates to a flow regulating device, in particular to a liquid fertilizer flow regulating device, a fertilization system and a method, and belongs to the field of agricultural machinery. Background technique [0002] Liquid fertilizer application is a fertilization technology that has been used in agricultural production in recent years. Compared with solid fertilizers, liquid fertilizers have the characteristics of low production cost, convenient application, and high nutrients that are conducive to crop absorption. However, the traditional continuous quantitative spraying method, Can not meet the actual requirements of agricultural production. Therefore, the technology of variable application of liquid fertilizer has become an important development direction. [0003] Giles, D.K. et al. (Droplet size and spray pattern characteristics of an electronic flow controller for spray nozzles.1990) realized liquid fertilizer flow regulation by ...
