[0062] In specific implementation, the entire water and fertilizer irrigation machine is connected to an external power supply and controller for power supply and control. The first metering pump 603 and the second metering pump 609 are controlled by operating the controller.

[0063] like Figure 4-Figure 6 As shown, it also includes a feeding mechanism 7, and the number of the feeding mechanisms 7 is multiple; the feeding mechanism 7 includes a first corrugated soft bag 701 and a second corrugated soft bag 702; the first corrugated soft bag 701 is located on the top of the second corrugated soft bag 702, and a squeezing strip 11 that can move up and down and is horizontally arranged is arranged between the first corrugated soft bag 701 and the second corrugated soft bag 702, and a first one-way valve 708 and a second one-way valve 709 are installed on the top of the first corrugated soft bag 701, and the first one-way valve 708 It is connected to the first discharge pipe 703, and the second one-way valve 709 is connected to the feed pipe 612 in the proportional feeding mechanism 6 of the proportional foliar fertilizer; the third one-way valve 710 and the fourth one-way valve 711 are installed at the bottom of the second corrugated soft bag 702, the third one-way valve 710 is connected to the second discharge pipe 704, and the fourth one-way valve 711 is connected to the feed pipe 612 in the proportional feeding mechanism 6 of the proportional root fertilizer; the first corrugated soft bag 701 and the second corrugated soft bag 702 are both provided with a first spring 707.

[0064] A fixing frame 8 is fixedly installed in the protective shell 1 , and the fixing frame 8 is located on the top of the feeding mechanism 7 . The bottom surface of the fixing frame 8 is fixedly connected to the top surface of the first corrugated soft bag 701 , and the bottom surface of the second corrugated soft bag 702 is fixedly connected to the bottom inner wall of the protective shell 1 .

[0065] A vertical first telescopic rod 9 is fixedly installed on the top of the fixed frame 8, and a sliding sleeve 1101 is fixedly connected to the output shaft end of the first telescopic rod 9, and the inner wall of the sliding sleeve 1101 is cooperated and connected with the extrusion strip 11; a vertical second telescopic rod 10 is also fixedly installed on the top of the fixed frame 8, and an end sleeve 1102 is fixedly connected to the output shaft end of the second telescopic rod 10, and the end sleeve 1102 is sleeved with one end of the extrusion strip 11; a guide column 12 is fixedly installed on the top surface of the end sleeve 1102, and the guide column 12 is cooperated and connected with a guide sleeve 13 arranged on the fixed frame 8.

[0066] When carrying out root fertilizer transportation, squeeze bar 11 as Figure 4 In the state shown, the first corrugated soft bag 701 and the second corrugated soft bag 702 are both in an uncompressed deformation state; the first telescopic rod 9 and the second telescopic rod 10 are extended to drive the extrusion bar 11 downward to extrude the second corrugated soft bag 702, so that the second corrugated soft bag 702 shrinks and compresses the first spring 707 therein, and the water and fertilizer in the second corrugated soft bag 702 are squeezed out and discharged through the second discharge pipe 704, and then enter the delivery pipe 14 for delivering root fertilizer through the second corrugated hose 706 and the interface 15, so as to deliver the root fertilizer, and then the first telescopic rod 9 and the second telescopic rod 10 are contracted to make the extrusion bar 11 reset upward and return to the state as shown. Figure 4 In the state shown, the second corrugated soft bag 702 is reset by the elastic force of the first spring 707, which sucks the water and fertilizer in the mixing box 602 through the feeding pipe 612. The water and fertilizer enter through the feeding pipe 612 and the fourth one-way valve 711 to replenish the water and fertilizer in the second corrugated soft bag 702; through the above-mentioned repeated operations, the continuous delivery of root fertilizer is achieved to provide water and fertilizer for the root drip irrigation assembly in the irrigation pipe 2.

[0067] When carrying out leaf fertilizer delivery, the squeezing bar 11 begins like Figure 4 In the state shown, the first corrugated soft bag 701 and the second corrugated soft bag 702 are both in an uncompressed deformation state; the first telescopic rod 9 and the second telescopic rod 10 are contracted to drive the extrusion bar 11 upward to extrude the first corrugated soft bag 701, so that the first corrugated soft bag 701 is contracted and the first spring 707 therein is compressed, and the water fertilizer in the first corrugated soft bag 701 is squeezed out and discharged through the first discharge pipe 703, and then enters the conveying pipe 14 for conveying leaf fertilizer through the first corrugated hose 705 and the interface 15 to realize the conveying of leaf fertilizer, and then the first telescopic rod 9 and the second telescopic rod 10 are extended to make the extrusion bar 11 return downward and return to the state shown in the figure. Figure 4In the state shown, the first corrugated soft bag 701 is reset by the elastic force of the first spring 707, which sucks the water and fertilizer in the mixing box 602 through the feeding pipe 612. The water and fertilizer enter through the feeding pipe 612 and the second one-way valve 709 to replenish the water and fertilizer in the first corrugated soft bag 701; through the above-mentioned repeated operations, the continuous delivery of leaf fertilizer is realized to provide water and fertilizer for the leaf spraying assembly in the irrigation pipe 2.

[0068] In a specific implementation, the first telescopic rod 9 and the second telescopic rod 10 are preferably electric push rods, air cylinders or hydraulic cylinders.

[0069] A solenoid valve may be installed in the interface 15 to control the opening and closing of the interface 15 .

[0070] The first telescopic rod 9 and the second telescopic rod 10 are used to drive the extrusion bar 11 to move up and down, and can drive the irrigation pipe 2 to move up and down together, so as to spray water and fertilizer on leaves at different heights of crops.

[0071] The second corrugated soft bag 702 is configured to be flat, so that during root drip irrigation, the irrigation pipe 2 only moves up and down a small distance near the root of the crop and does not deviate from the root position.

[0072] Through the above design, all feeding mechanisms 7 drive water and fertilizer through the extension and retraction of the first telescopic rod 9 and the second telescopic rod 10. At the same time, when spraying foliar fertilizer at different heights of crops, the irrigation pipe 2 is moved up and down through the extension and retraction of the first telescopic rod 9 and the second telescopic rod 10, so that the leaf spraying assembly can spray crops at different heights.

[0073] like Figure 7 As shown, an electromagnet 1104 is fixedly installed at one end of the end sleeve 1102 away from the extrusion strip 11, a connecting rod 1105 is fixedly installed at the end of the extrusion strip 11, and a permanent magnet block 1106 that repels the electromagnet 1104 when powered is fixedly connected to the end surface of the connecting rod 1105 facing the electromagnet 1104, a block seat 1107 is fixedly installed in the end sleeve 1102, a hole is opened on the block seat 1107 for the connecting rod 1105 to pass through, a second spring 1108 is sleeved on the connecting rod 1105, and both ends of the second spring 1108 are respectively fixedly connected to one end surface of the extrusion strip 11 and the block seat 1107.

[0074] The extrusion strip 11 can move up and down as well as horizontally. Before the irrigation pipe 2 is used for root drip irrigation, the irrigation pipe 2 is moved horizontally, and the drip irrigation port 203 of the irrigation pipe 2 is close to the root.

[0075] Before leaf irrigation, the irrigation pipe 2 is moved laterally away from the root so that the center of the annular tube 205 is located at the crop, so that the annular tube 205 can move up and down with the irrigation pipe 2 and the crop can be evenly sprayed through the nozzles 206 around it.

[0076] like Figure 7 As shown, at this time, the electromagnet 1104 is in a powered-on state, providing a repulsive force for the permanent magnet block 1106, and making the second spring 1108 in a stretched state, in which the irrigation pipe 2 is laterally away from the crop roots; by disconnecting the power to the electromagnet 1104, the permanent magnet loses its magnetic repulsive force, and the elastic force of the second spring 1108 drives the extrusion bar 11, the connecting rod 1105 and the permanent magnet block 1106 to move laterally together, the permanent magnet block 1106 approaches the electromagnet 1104, and the irrigation pipe 2 approaches the crop roots laterally.

[0077] When the irrigation pipe 2 is moved laterally away from the crop roots, the electromagnet 1104 is energized again, and the permanent magnet block 1106 moves away from the electromagnet 1104 through the repulsive force of the electromagnet 1104 until the permanent magnet block 1106 contacts the blocking seat 1107 and is blocked. The permanent magnet block 1106 moves and drives the extrusion bar 11 to move through the connecting rod 1105, so that the irrigation pipe 2 is moved laterally away from the crop roots.

[0078] It should be noted that the lateral movement adjustment of the extrusion strip 11 is as follows: Figure 4 Performed in the status shown.
