Description

Technical Field

[0001] The invention relates to the technical field of saline-alkali land irrigation, and in particular to a saline-alkali land water and fertilizer irrigation device based on a soil crop spectral information model. Background Art

[0002] Many saline-alkali lands use drip irrigation, sprinkler irrigation, scar irrigation, root-dividing alternating irrigation and other irrigation methods to achieve the purpose of water conservation and salt control, and create a local desalination "water and fertilizer storage layer". The scar irrigation system generally buries the scar irrigation pipe at a certain soil depth, that is, the depth of the plant root system. Traditional irrigation methods in the prior art often have problems such as uneven irrigation and serious water waste, which affects plant growth and irrigation efficiency, resulting in poor use effects and is not conducive to later saline-alkali land farming.

[0003] In order to overcome the above-mentioned defects, an irrigation device for saline-alkali land management with publication number CN119032834A includes a main water pipe mechanism, including a main water pipe assembly, and a branch pipe arranged on the main water pipe assembly; a water supply pipe mechanism, including a water supply pipe assembly interconnected with the branch pipe, and an extension pipe assembly installed on the water supply pipe assembly; the water supply pipe assembly includes a connecting hose, one end of which is fixedly connected to an external joint; the present invention can adapt to the irrigation needs of saline-alkali land of different sizes and shapes through the flexible connection of multiple sections of main water pipe assemblies, ensuring that water is stably and efficiently delivered to each irrigation point; through the arrangement of the water supply pipe assembly and the extension pipe assembly, it is not only convenient to install and adjust the position, but also can effectively surround the seedlings to achieve precise irrigation, and the arrangement of the positioning rod enables the irrigation device to be firmly inserted into the soil to avoid displacement or separation during the irrigation process.

[0004] Although the existing design can solve the above problems, it is not convenient to make manual adjustments when large-scale mobile broadcasting irrigation is required. In addition, the fertilizer water used in water and fertilizer irrigation is not mixed evenly, which cannot achieve good nutrient replenishment, resulting in different nutrient supplements in saline-alkali land. It is not possible to perform convenient proportioning operations according to the fertilizer and water ratio requirements, and the uncertainty of the proportion concentration is too high. Summary of the invention

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a saline-alkali land water and fertilizer irrigation device based on a soil crop spectral information model, comprising a water and fertilizer mixing barrel installed inside the installation bucket, and a water inlet is opened on the top of the water and fertilizer mixing barrel, a flexible water spray head is installed on the side of the water and fertilizer mixing barrel, and the water and fertilizer mixing barrel, the water inlet and the flexible water spray head are all designed to be internally connected, a fixed support plate is installed inside the installation bucket, and an engaging sliding structure for reciprocating rotation of a swing rod is installed on the inner surface of the fixed support plate, the engaging sliding structure includes a driving motor, and a semicircular rotating gear is installed at the output end of the driving motor, a fixed reset plate is installed on the side of the semicircular rotating gear, and a reset spring is installed inside the fixed reset plate; a supporting fixing frame is installed inside the installation bucket, and an elastic sliding structure for continuously opening and closing a current limiting blocking plate is installed inside the supporting fixing frame.

[0008] Furthermore, a fixed limit frame is installed inside the fertilizer storage barrel, and a downward pressure resistance spring is installed on the lower surface of the fixed limit frame, a flow limiting blocking plate is installed at the lower end of the downward pressure resistance spring, and a nested movable frame is installed on the outer surface of the flow limiting blocking plate, the nested movable frame is hollow in design, and the nested movable frame is fixedly installed inside the fertilizer storage barrel, the diameter of the flow limiting blocking plate is larger than the hollow diameter of the nested movable frame, and movable grooves are provided on the sides of the movable limit mouth and the nested movable frame.

[0009] Furthermore, the front end of the reset spring is fixedly installed inside the fixed reset plate, and the other end of the reset spring is installed with a sliding gear rod, the sliding gear rod is slidably installed on the upper surface of the fixed reset plate, and the side surface of the fixed reset plate is in contact with the semicircular rotating gear, and the other side of the sliding gear rod is installed with a transmission gear, and the transmission gear is rotatably installed on the top of the water-fertilizer mixing barrel.

[0010] Furthermore, a swing rod is installed on the lower surface of the transmission gear, and the bottom end of the swing rod rotates inside the water-fertilizer mixing barrel, and the fixed reset plate is fixedly installed on the top of the water-fertilizer mixing barrel, and the drive motor is fixedly installed on the inner surface of the fixed support plate, and the semicircular rotating gear is a semicircular design.

[0011] Furthermore, the outer surface of the semicircular rotating gear contacts the side of the sliding gear rod to form a meshing structure, and the side of the sliding gear rod contacts the outer surface of the transmission gear to form a meshing structure, and the end of the return spring contacts the top of the sliding gear rod to form an elastic structure.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1-Figure 6 The present invention provides the following technical solutions: a saline-alkali land water and fertilizer irrigation device based on a soil crop spectral information model, comprising a mounting bucket 1, a water and fertilizer mixing barrel 2 and a fixed limit frame 21. A water and fertilizer mixing barrel 2 is mounted inside the mounting bucket 1, and a water inlet 3 is provided on the top of the water and fertilizer mixing barrel 2, a flexible water spray head 11 is mounted on the side of the water and fertilizer mixing barrel 2, and the water and fertilizer mixing barrel 2 and the water inlet 3 and the flexible water spray head 11 are all designed to be internally connected, a fixed support plate 4 is mounted inside the mounting bucket 1, and an engaging sliding structure for reciprocatingly rotating a swing rod 16 is mounted on the inner surface of the fixed support plate 4, the engaging sliding structure comprises a driving motor 5, and a semicircular rotating gear 6 is mounted on the output end of the driving motor 5, a fixed reset plate 7 is mounted on the side of the semicircular rotating gear 6, and a reset spring 8 is mounted inside the fixed reset plate 7; a supporting fixed frame 13 is mounted inside the mounting bucket 1, and an elastic sliding structure for continuously opening and closing a flow limiting blocking plate 18 is mounted inside the supporting fixed frame 13.

[0025] like Figure 2 , Figure 3 , Figure 4The technical solution shown in the figure, in order to solve the problem that it is inconvenient to carry out maintenance manually when a fault occurs, discloses: the elastic sliding structure includes a fertilizer storage barrel 12, and the fertilizer storage barrel 12 is fixedly installed inside the support fixing frame 13, a movable limit mouth 14 is installed on the top of the fertilizer storage barrel 12, and a limit support plate 17 is installed inside the fertilizer storage barrel 12, a transmission fixing rod 15 is installed inside the movable limit mouth 14, and the transmission fixing rod 15 passes through the movable limit mouth 14 and the limit support plate 17, a fixed limit frame 21 is installed inside the fertilizer storage barrel 12, and a downward pressure resistance is installed on the lower surface of the fixed limit frame 21. The contact spring 20 is pressed down, and a flow limiting blocking plate 18 is installed at the lower end thereof, and a nested movable frame 19 is installed on the outer surface of the flow limiting blocking plate 18. The nested movable frame 19 is hollow in design, and the nested movable frame 19 is fixedly installed inside the fertilizer storage barrel 12. The diameter of the flow limiting blocking plate 18 is larger than the hollow diameter of the nested movable frame 19, and movable grooves are provided on the sides of the movable limit mouth 14 and the nested movable frame 19. The inner surface of the movable limit mouth 14 contacts the outer surface of the transmission fixed rod 15 to form a sliding structure, and the lower surface of the transmission fixed rod 15 is fixedly installed on the top of the flow limiting blocking plate 18.

[0026] When it is necessary to mix fertilizer and water, first pull the internally nested transmission fixing rod 15 upward along the inside of the movable limiting mouth 14. While passing through the inside of the movable limiting mouth 14, the transmission fixing rod 15 also passes through the inside of the limiting support plate 17 fixedly installed inside the fertilizer storage barrel 12, ensuring the sliding stability of the transmission fixing rod 15. When the transmission fixing rod 15 slides upward, it drives the flow limiting blocking plate 18 fixedly installed at the end to slide upward synchronously, and the sliding process is carried out inside the nested movable frame 19. The diameter of the hollow position of the nested movable frame 19 is smaller than the diameter of the flow limiting blocking plate 18. Therefore, when the flow limiting blocking plate 18 slides upward, the nested movable frame 19 is opened to transport the fertilizer stored in the fertilizer storage barrel 12 to the water-fertilizer mixer connected to it. The next step of stirring is carried out inside the mixing barrel 2, and while the flow limiting blocking plate 18 moves upward, the flow limiting blocking plate 18 squeezes the downward pressure resistance spring 20 fixedly installed on the upper surface, and the upper end of the downward pressure resistance spring 20 is fixed by the fixed limiting frame 21 fixedly installed on the inner surface of the fertilizer storage barrel 12 to keep the upper end position unchanged. After completing the fertilizer transportation work, the downward pressure resistance spring 20 releases the elastic potential energy to push the flow limiting blocking plate 18 downward, and completes the blockage again along the inside of the nested moving frame 19 to ensure that the ratio concentration of fertilizer and water will not cause accidental leakage, and different concentrations can also be mixed according to different saline-alkali lands according to needs to obtain better practicality, and the supporting fixing frame 13 on the outer surface of the fertilizer storage barrel 12 also makes the installation more stable.

[0027] like Figure 2 , Figure 3 , Figure 4 The technical solution shown, in order to solve the problem that it is inconvenient to perform maintenance manually when a fault occurs, discloses that: the front end of the reset spring 8 is fixedly installed inside the fixed reset plate 7, and the other end of the reset spring 8 is installed with a sliding gear rod 9, the sliding gear rod 9 is slidably installed on the upper surface of the fixed reset plate 7, and the side of the fixed reset plate 7 is in contact with the semicircular rotating gear 6, the other side of the sliding gear rod 9 is installed with a transmission gear 10, and the transmission gear 10 is rotatably installed on the top of the water-fertilizer mixing barrel 2, the lower surface of the transmission gear 10 is installed with a swing rod 16, and the bottom end of the swing rod 16 rotates inside the water-fertilizer mixing barrel 2, and the fixed reset plate 7 is fixedly installed on the top of the water-fertilizer mixing barrel 2, and the drive motor 5 is fixedly installed on the inner surface of the fixed support plate 4, and the semicircular rotating gear 6 is semicircular in design, the outer surface of the semicircular rotating gear 6 and the side of the sliding gear rod 9 are in contact with each other to form a meshing structure, and the side of the sliding gear rod 9 is in contact with the outer surface of the transmission gear 10 to form a meshing structure, and the end of the reset spring 8 is in contact with the top of the sliding gear rod 9 to form an elastic structure.

[0028] In order to make the stirring of fertilizer water more efficient and convenient, when stirring and mixing work is needed, it is only necessary to start the driving motor 5 fixedly installed on the inner surface of the fixed support plate 4 to work. The semicircular rotating gear 6 fixedly installed on the output end of the driving motor 5 rotates back and forth through the driving work. The rotation of the semicircular rotating gear 6 drives the sliding gear rod 9 that contacts each other on the side to produce meshing movement. The sliding gear rod 9 slides backward along the upper surface of the fixed reset plate 7 under the drive of the meshing movement, and drives the mutual reset springs 8 on the top to extend and lengthen synchronously during the sliding process of the fixed reset plate 7. Since the semicircular rotating gear 6 is a semicircular design, the semicircular rotating gear 6 is disengaged from the sliding gear rod 9 after the semicircular rotating gear 6 rotates half a circle. After the sliding gear rod 9 is disengaged from it, it is driven by the reset spring 8 fixed on the top to release the elastic potential energy again. The sliding gear rod 9 is pulled back upward to complete the reciprocating sliding movement on the upper surface of the fixed reset plate 7. When the sliding gear rod 9 performs reciprocating sliding movement, the transmission gear 10 that contacts each other on the right side of the sliding gear rod 9 is driven to produce meshing movement. Since the transmission gear 10 is rotatably installed on the top of the water-fertilizer mixing barrel 2, the transmission gear 10 reciprocates on the top of the water-fertilizer mixing barrel 2 driven by the meshing movement, and the swing rod 16 is fixedly installed on the lower surface of the transmission gear 10, so the swing rod 16 rotates synchronously with the rotation of the transmission gear 10. The reciprocating rotation of the swing rod 16 enables the water and fertilizer inside the water-fertilizer mixing barrel 2 to achieve efficient mixing ratio, and the water volume can be added through the water inlet 3 at the upper end of the water-fertilizer mixing barrel 2. After completing the ratio, the installation bucket 1 is pushed and the flexible sprinkler head 11 can be used for irrigation when it reaches the saline-alkali land irrigation location.
