Description

Technical Field

[0001] The invention relates to the technical field of water-fertilizer irrigation, and in particular to a saline-alkali land water-fertilizer irrigation integrated machine provided with a salt monitoring mechanism. Background Art

[0002] The integrated water-fertilizer irrigation machine is a machine that can irrigate and fertilize crops. During use, the fertilizer needs to be added into the water to melt and then transported to the farmland through the water flow. However, the existing integrated water-fertilizer irrigation machine still has certain usage defects during use. When adding fertilizer to the existing integrated water-fertilizer irrigation machine, the fertilizer may clump due to external reasons, and the existing integrated water-fertilizer machine does not have the function of breaking up the clumped fertilizer, which makes the dissolution effect of fertilizer and water worse.

[0003] Patent authorization announcement number CN220402370U discloses a water-fertilizer irrigation integrated machine with a crop nutrient demand analysis function. By setting a carrier plate and a mixing barrel as the supporting body and assembling a feeding component and a metering control component, liquid fertilizer and non-liquid fertilizer are placed separately in two feeding barrels. When the analysis and control host inputs the variety and growth cycle data of the fertilized crop, the system database analyzes the reasonable fertilizer ratio and controls the operation of the drive motor and the solenoid valve. Liquid fertilizer and non-liquid fertilizer are separately introduced from the feed pipe to the feed pipe through the opening and closing state of the corresponding solenoid valve. The operation of the drive motor can use its output shaft to drive the spiral blade to rotate. The single-form fertilizer introduced into the feed pipe is pushed to the vertical pipe by the spiral blade and falls into the mixing barrel. The flow meter installed on the vertical pipe measures the fertilizer input amount and transmits a signal to the analysis and control host. When the appropriate amount is reached, the solenoid valve is controlled to close, and the other solenoid valve is opened, and the other form of fertilizer is then fed and metered. The fertilizer input amount and ratio are effectively controlled, and the overall ratio of the equipment is accurate and simple while ensuring a reasonable and scientific fertilization effect.

[0004] Patent authorization announcement number CN216058271U discloses a channel strawberry-specific intelligent water-fertilizer irrigation integrated machine. Through the coordination of the set sensor, irrigator and movable rod, the irrigator cooperates with the activity of the movable rod to make the mobile irrigation method replace the traditional manual operation of the machine, and the sensor detects the growth height of the plant and cooperates with the amount of irrigation to make the water and fertilizer operation more intelligent, minimize the degree of inconsistency between the concentration generated by the machine and the crop demand, and minimize the jump amplitude and number of target concentrations. The best cluster irrigation control effect of the greenhouse water and fertilizer integrated machine is achieved, so as to achieve the effect of using different pressurization methods of the opening and closing disc to make the nozzle have different working modes, so that the plants in some areas can be irrigated in a targeted and quantitative manner more accurately, avoiding uneven diffusion of water and fertilizer and uneven irrigation.

[0005] In the above-mentioned public patent, the integrated water-fertilizer machine in the patent solves the above-mentioned problems, but the integrated water-fertilizer machine still has the following problems. During the use of the integrated fertilizer machine, it is necessary to complete the irrigation and fertilization process through the water inlet pipe and the water outlet pipe.

After the integrated machine is placed at the required position, the water inlet pipe 3 and the water outlet pipe 4 on the outside of the integrated machine can be connected by pipes. After the pipe connection is completed, the integrated machine can be used for irrigation and fertilization. During the operation of the integrated machine, the suction mechanism 5 will work and complete the water transportation through the water inlet pipe 3 and the water outlet pipe 4 to achieve irrigation of crops.

[0035] Embodiment 2: This embodiment is as follows Figure 1-Figure 2 and Figure 5-Figure 6As shown, in order to solve the problem that the existing all-in-one machine is prone to clogging, the process of automatic impurity removal of the all-in-one machine is disclosed, and the effect of preventing the all-in-one machine from being blocked is achieved. The specific contents are as follows: the interior of the water inlet pipe 3 is provided with an impurity removal structure for filtering impurities in the water; the impurity removal structure includes a filter frame 17, a fixed block 18 and a receiving frame 19, the filter frame 17 is fixedly installed inside the water inlet pipe 3, and two groups of fixed blocks 18 are fixedly installed on the outside of the filter frame 17, and the receiving frame 19 is clamped and installed at the lower end of the filter frame 17; a cleaning brush 21 is slidably installed inside the filter frame 17, and a connecting rod 22 is fixedly installed at the lower end of the cleaning brush 21, and the connecting rod 22 is A fixed pull rod 23 is fixedly installed at the lower end, and the fixed pull rod 23 is located inside the receiving frame 19; a filter plate 20 is nested and installed inside the filter frame 17, and the filter plate 20 is tightly fitted with the water inlet pipe 3, and a spacing rod 24 and an ejection block 25 are fixedly installed inside the receiving frame 19, and the spacing rod 24 and the ejection block 25 are respectively located at the upper ends of the fixed pull rod 23; a limit block 26 is slidably installed inside the fixed block 18, and a return spring 27 is fixedly installed on one end of the limit block 26 close to the fixed block 18, and the return spring 27 is fixedly connected to the fixed block 18, and the end of the fixed block 18 away from the return spring 27 is engaged and connected with the receiving frame 19.

[0036] When the saline-alkali land water and fertilizer irrigation integrated machine with a salt monitoring structure is used, water will enter through the water inlet pipe 3, and the filter plate 20 inside the filter frame 17 will remove impurities such as weeds in the water flow to avoid clogging of the integrated machine after long-term use; in this process, it is necessary to make the filter plate 20 filter the impurities and make the impurities fall into the inside of the receiving frame 19, and the receiving frame 19 is made of transparent material, so the impurity situation inside the receiving frame 19 can be directly observed, and it can be cleaned at any time when there are too many impurities. During the cleaning process, the integrated machine needs to be in a standby state; in the process of removing the receiving frame 19, it is necessary to directly pull the receiving frame 19 downward, at this time, the receiving frame 19 will separate from the limit block 26 and make the limit block 26 slide to the inside of the fixed block 18 The support frame 19 moves, and the movement of the limit block 26 will squeeze the return spring 27 and cause the return spring 27 to contract. During the downward movement of the support frame 19, the fixed pull rod 23 will be pulled to move through the two sets of spacing rods 24. The fixed pull rod 23 will follow the support frame 19 to move downward and pull the cleaning brush 21 downward through the connecting rod 22. At this time, the downward movement of the cleaning brush 21 will clean the impurities adhered to the outside of the filter plate 20, thereby ensuring the cleanliness of the filter plate 20, and after the support frame 19 is separated from the filter frame 17, the support frame 19 is rotated to separate the fixed pull rod 23 from the two sets of spacing rods 24, so that the support frame 19 can be removed and cleaned to ensure the filtering effect of the filter plate 20. By disassembling the support frame 19, the filtering and impurity removal effect of the all-in-one machine can be ensured.

[0037] Embodiment 3: This embodiment is as follows Figure 1-Figure 2 and Figure 7-Figure 8 As shown, in order to solve the problem of uneven fertilizer distribution inside the existing all-in-one machine, the working process of the internal mixing structure of the all-in-one machine is disclosed, and the all-in-one machine can ensure the effect of balanced fertilization. The specific contents are as follows: a mixing structure for controlling the balanced discharge of fertilizer is arranged inside the machine body 1; the mixing structure includes a driving motor 28 and a rotating tube 29, the driving motor 28 is fixedly mounted on the upper end of the machine body 1, and the output end of the driving motor 28 is fixedly mounted with the rotating tube 29, and the rotating tube 29 is rotatably connected to the machine body 1, and a rotating frame 3 is fixedly mounted inside the rotating tube 29 0, and a rotating shaft 31 is rotatably installed inside the rotating frame 30, and a stirring plate 32 is fixedly installed on the end of the rotating shaft 31 away from the rotating frame 30, and a bevel gear 1 33 is fixedly installed on the end of the rotating shaft 31 close to the rotating frame 30, and the bevel gear 1 33 is located inside the rotating frame 30; the mixing structure also includes a positioning rod 36, and the positioning rod 36 is fixedly installed on the upper end of the isolation plate 6, and the positioning rod 36 is located inside the rotating tube 29, and a bevel gear 2 34 is fixedly installed on the outer side of the positioning rod 36, and the bevel gear 2 34 is meshed with the bevel gear 1 33.

[0038] During the use of the all-in-one machine, it is necessary to allow the water flow containing fertilizer at the upper end of the isolation plate 6 to enter the interior of the suction mechanism 5 and be discharged through the water outlet pipe 4. During this process, solid fertilizer or liquid fertilizer needs to be added to the upper end of the body 1 through the filling port 35, and then the fertilizer can be integrated into the water flow and fertilization can be carried out; after the fertilizer is dissolved in the water flow at the upper end of the isolation plate 6, the density of the fertilizer liquid is greater than the density of the water flow, which will cause the fertilizer solution to accumulate at the lower end of the water flow, and it is easy to cause uneven distribution of fertilizer in the water flow, affecting the fertilization effect in crop irrigation; at this time, the driving motor 28 needs to work and drive the rotating tube 29 to rotate, and at this time, the rotating tube 29 can drive the rotating frame 30 to move, and the rotating frame 30 moves The rotating shaft 31 will be driven to rotate. At this time, the rotating shaft 31 will drive the stirring plate 32 and the bevel gear 1 33 to move synchronously. During the rotation of the bevel gear 1 33, it will always maintain a meshing state with the bevel gear 2 34, so that the bevel gear 1 33 can be rotated and drive the rotating shaft 31 and the stirring plate 32 to rotate vertically. At this time, the stirring plate 32 will rotate synchronously in the horizontal and vertical directions, and during the rotation of the stirring plate 32, the water flow at the upper end of the isolation plate 6 will flow up and down, so that the fertilizer liquid in the water flow is evenly distributed, ensuring that the fertilizer content in the water flow discharged by the discharger 8 is balanced, which can ensure the fertilization effect on crops during the irrigation process of the all-in-one machine, thereby improving the comprehensiveness of the use of the fertilizer spreader and increasing the overall practicality.
