It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

The first embodiment is as follows:

as shown in fig. 1, the embodiment provides a sprinkling irrigation and fertilization device for a grain field, which comprises a water pump 3 and a fertilization barrel 4, wherein the water pump 3 is communicated with the fertilization barrel 4 through a pipeline to form a closed circulation pipeline, and a valve II2 is arranged on the closed circulation pipeline; the closed circulation pipeline is communicated with the main waterway pipeline 5 through a pipeline, and a valve I1 is arranged on the pipeline between the closed circulation pipeline and the main waterway pipeline 5.

In order to facilitate the connection of the device of this embodiment with main waterway pipeline 5, the end of the pipeline connected with main waterway pipeline 5 is provided with a quick movable joint. The quick movable joint is a standard component, and the specific structure thereof is not described in detail herein.

In the embodiment, the water pump 3 adopts an XKJ-804S centrifugal injection pump, the XKJ-804S centrifugal injection pump adopts a unique structure of a centrifugal impeller-radial guide vane-ejector, the working principle is that pressure water firstly passes through a nozzle to cause vacuum, then low-pressure water level liquid is sucked into a pump inlet and is discharged after being pressurized by the pump, the pump body, the pump cover and the pump shaft are made of stainless steel materials, and the motor is an asynchronous motor, so that the pump has the characteristics of deep suction lift, high lift, short self-suction time and stable operation, and the problem of difficult fertilizer injection does not occur through tests.

In the selection of the valve, the characteristics and practical application of the electric valve and the electromagnetic valve are compared. The electromagnetic valve controls the opening and closing of the valve by using electromagnetic field suction force (matched with a spring) generated by an electromagnetic coil, so that a certain time delay is required from the opening to the closing, and the field actual measurement value is 15 s. When fertilizer need be annotated after fertilizer dissolves evenly, valve II from opening to closing completely and have the time delay of 15s, and this in-process water pump still is in the inner loop state, and the water of water route trunk line gets into the fertilization bucket under the pressure, leads to liquid manure mixture to spill over the fertilization bucket. The electric valve has the working principle that the electric actuator is used for controlling the valve, the valve can be opened and closed in time, the requirement of logic relation is met, and meanwhile, the volume of the electric valve is smaller than that of the electromagnetic valve, so that the fertilizer injection pump and the pipeline arrangement are facilitated. Thus, the valves I1 and II2 of this example use a quick/adhesive electric valve (DN25/DC24V) model QQ 93103-25.

To facilitate an understanding of the present embodiment, it is further described below in connection with its use:

when the fertilizer applying device is used, fertilizer is firstly added into the fertilizer applying barrel 4, the valve I1 and the valve II2 are both opened, the water pump 3 is closed, and as shown by dotted arrows in figure 1, the main waterway pipeline 5 injects water into the fertilizer applying barrel 4. After the water is filled, the valve I1 is closed, the valve II2 and the water pump 3 are opened, as shown by hollow arrows in figure 1, and the water and fertilizer mixed liquid circularly flows in a closed circulation pipeline between the water pump 3 and the fertilization bucket 4, so that the water and the fertilizer are fully mixed in the fertilization bucket 4. After the water and the fertilizer are uniformly mixed, the valve II2 is closed, the valve I1 and the water pump 3 are opened, as shown by solid arrows in fig. 1, under the pressure of the water pump 3, the water and fertilizer mixed liquid is injected into the main waterway pipeline 5, and the fertilizer injection function is completed.

Before use, preferably, clear water is irrigated for about 30min, so that irrigation equipment works normally and water is sprayed uniformly; after the fertilizer liquid is injected, the clear water is continuously irrigated for more than 30min, the fertilizer liquid on the water delivery pipeline and the crop leaves is washed, and the phenomenon that the underground water is polluted or the fertilizer liquid is remained on the leaves to burn seedlings due to backflow of the fertilizer liquid is avoided.

The utility model discloses grain field sprinkling irrigation fertilizer injection unit of example only adopts a water pump and a fertilization bucket, through the cooperation of valve, realizes functions such as water injection, liquid manure mixture and notes fertilizer, and the device constitutes the part few, compact structure, and need not agitating unit, the energy can be saved.

Water route trunk line 5 intercommunication water source and sprinkling irrigation pipeline set up the check valve in one side that the tie point of water route trunk line 5 and water pump 3 is close to the water source, can enough guarantee water injection smoothly, and liquid is mixed to liquid influences the water source when can avoiding annotating fertile again.
