When fertilizing, straight line module 6 takes mixing box 1 to move through connecting block 61, and then changes mixing box 1's position.
The specific implementation process is as follows:
send into water in to mixing box 1 through water pump 7 and pipeline 71, open the second valve simultaneously, the chemical fertilizer in the chemical fertilizer chamber 31 is through entering into pipeline 71 through chemical fertilizer pipe 32 along hang plate 34 in, chemical fertilizer and water intensive mixing under the shearing action power of water, and in water and the mixed liquid of chemical fertilizer entered into mixing box 1, the shearing action of water is equivalent to the stirring. In this embodiment, the flow rate of water is: 0.5t/min, the flow of the fertilizer is as follows: and 10g/min, the volume of the mixed liquid of the fertilizer and the water entering the mixing box 1 is 0.5 cubic meter. Referring to fig. 3, the mixed liquid horizontally enters the mixing tank 1, after the valve is opened, the water in the pipeline 71 vertically enters the mixing tank 1, and the water and the fertilizer are further stirred by the horizontal and vertical acting forces, so that the fertilizer and the water are fully mixed.
After mixed liquid enters into mixing box 1, mixed liquid can extrude the interior air of mixing box 1 to chemical fertilizer chamber 31 through gas pocket 33 and check valve 35 in, under the effect of gas, can make the chemical fertilizer take place not hard up, and then do benefit to the chemical fertilizer and slide to chemical fertilizer pipe 32 along hang plate 34, reduce the probability that the chemical fertilizer piles up at hang plate 34.
After the mixed liquid enters the mixing box 1, the baffle plate 11 is pushed to move towards the right side under the action of the mixed liquid pressure. The baffle 11 pushes the closing frame 54 to move towards the right, the lower end of the closing frame 54 opens part of the spray pipes 52, and the mixed solution of 0.5 cubic meter in the embodiment pushes the closing frame 54 to open three spray pipes 52. The first valve 56 is opened, the mixed liquid enters the fertilizing box 5 through the fertilizing pipe 51, the air pump in the fertilizing box 5 sends air into the fertilizing box 5, the air pressure in the fertilizing box 5 is increased, and the mixed liquid in the fertilizing box 5 is sprayed out through the opened spraying pipe 52 and the spraying nozzle 53, so that the purpose of fertilizing is achieved. In the fertilization process, the straight line module 6 drives the fertilization box 5 to move horizontally, and then the purpose of adjusting the position of the mixing box 1 is achieved, so that the uniform fertilization is ensured.
In the embodiment, in the fertilizing process, the number of the spraying pipes 52 is controlled to control the fertilizing time and efficiency, so that the phenomenon that the fertilizing time is too long or too short is avoided, and the condition that the soil planned to be fertilized can be fertilized is ensured. Secondly, when fertilizing, if there is a plant on the soil, after the mixed liquid in the fertilizing box 5 is discharged, the air pump discharges the gas through the fertilizing box 5, the spray pipe 52 and the spray nozzle 53, the gas blows the fertilizer adhered on the surface of the plant to the soil to improve the absorption of the plant to the fertilizer, and after one-time fertilization, the above work is repeated.
Example two:
the difference between the second embodiment and the first embodiment is that, as shown in fig. 6 and 7, a plurality of brackets 72 are fixed to the pipe 71 through bolts, the longitudinal section of each bracket 72 is circular, in this embodiment, three brackets 72 (not shown) are provided, and the fertilizer pipe 32 is located between two adjacent brackets 72. The bracket 72 is provided with a guide groove 73 with a circular longitudinal section, three blades 74 are connected in the guide groove 73 in a sliding manner, and the other ends of the blades 74 are fixed by bolts.
The specific implementation process is as follows:
when the water in the pipeline 71 passes through the first bracket 72, the water flows and drives the blades 74 to rotate, so that the water flow forms turbulent flow, the fertilizer enters the water, stirring is formed under the action of the turbulent flow, and the water and the fertilizer are fully stirred and mixed. When passing through the second support 72, the rotating blades 74 cut the water and fertilizer, further mixing the fertilizer with the water, and increasing the efficiency of dissolving the fertilizer in the water. Water and fertilizer act the same as they pass through the third support 72.
In this embodiment, the water and fertilizer are fully stirred by the stirring of the blades 74 on the bracket 72, so that the undissolved amount of the fertilizer is reduced, and the residual amount of the fertilizer in the mixing box 1 is further reduced.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make several variations and modifications without departing from the concept of the present invention, and these should be considered as the protection scope of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent. The techniques, shapes, and structural parts, which are omitted from the description of the present invention, are all known techniques.
