Description

Technical Field

[0001] The invention relates to the technical field of integrated fertilization, and in particular to a multi-channel water-fertilizer machine. Background Art

[0002] my country is a large agricultural country, with agricultural water consumption accounting for 80% of the total water consumption, of which the vast majority is used for crop irrigation. The integrated water-fertilizer technology is a new agricultural technology that integrates irrigation and fertilization. It supplies water and fertilizer through a controllable pipeline system. After the water and fertilizer are mixed, drip irrigation is formed through pipes and drippers, evenly, regularly and quantitatively, infiltrating the root development and growth area of ​​crops, so that the main root soil always remains loose and has an appropriate water content. At the same time, it is based on the fertilizer requirements of different crops, soil environment and nutrient content.

[0003] At present, in the integrated water-fertilizer fertilization system, in the process of fertilizer-liquid blending, active fertilizer injection and passive fertilizer absorption by Venturi or proportional fertilizer pumps are mostly used. These methods have their own advantages and disadvantages. For most irrigations, water-fertilizer integrated irrigation should be carried out according to the needs of different types of fertilizers in different growth stages of crops. Therefore, the commonly used method at home and abroad is to supply different types of fertilizers through multiple channels. In the irrigation of integrated water-fertilizer machines, since multiple fertilizer pipelines inject fertilizer into the main water channel during the fertilizer injection process, it is easy to cause uneven mixing of fertilizers in the pipeline. At present, dynamic mixers or static mixers are used to mix various types of fertilizers. However, when a static mixer is used to mix fertilizer and water, the water flow is only blocked by fixed blades, which is easy to cause poor mixing effect and low mixing efficiency. Although the dynamic mixer can stir and mix the water flow with blades, it often requires an external power system to work, which is easy to increase the waste of resources. At the same time, only stirring is not conducive to the full mixing of water and fertilizer.

[0004] Therefore, a multi-channel water-fertilizer machine is invented to solve the above problems. Summary of the invention

[0038] 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.

[0039] Example 1

[0040] In traditional fertilization devices, fertilizer and water are generally mixed together manually in proportion, and the mixed liquid is discharged into the soil for irrigation and fertilization. This fertilization method not only causes uneven fertilizer ratios, but also is inconvenient to automatically prepare a variety of different fertilizers in different proportions, which is not conducive to better irrigation and fertilization. This embodiment is specially invented to solve the above problems.

[0041] like Figure 1-Figure 2 As shown, a multi-channel water-fertilizer machine according to an embodiment of the present invention comprises a mounting frame 1, a water pump 2 is mounted on the mounting frame 1, a water inlet of the water pump 2 is connected to an injection pipe 3, a water outlet of the water pump 2 is connected to an output pipe 4, a mixer 5 connected thereto is mounted on the output pipe 4, a plurality of vertically extending branch pipes 11 are connected to the injection pipe 3, a plurality of branch pipes 11 are commonly connected to a water injection pipe 12 at their upper ends, each branch pipe 11 is connected to a venturi pipe 13, each venturi pipe 13 is connected to a fertilizer injection pipe 14, and each fertilizer injection pipe 14 and the water injection pipe 12 are far away from the branch pipe 11. One end of each fertilizer injection pipe 14 is connected to a Y-type filter 15, and each fertilizer injection pipe 14 is connected to a flow meter 16, a solenoid valve 17 and a check valve 18 in sequence from bottom to top. A distribution cabinet 19 is installed on the mounting frame 1, and a control panel 20 is installed on the distribution cabinet 19 to control the opening and closing of the water pump 2 and the solenoid valve 17; wherein the flow meter 16, the solenoid valve 17, the check valve 18 and the venturi tube 13 are all prior art, and the specific structure is not repeated here, and the electrical connection relationship between the distribution cabinet 19 and the control panel 20, the solenoid valve 17 and the water pump 2 is all prior art, and the specific connection method is not repeated here.

[0042] When in use, first connect the free end of the water injection pipe 12 to the irrigation pool, and connect the free ends of the multiple fertilizer injection pipes 14 to fertilizer containers of different fertilizers. It should be noted that multiple sensors for detecting soil moisture and temperature and connected to the control panel 20 are arranged in the fertilization area. When the detection signal of the sensor is transmitted to the control panel 20, the staff operates the control panel 20 to set the irrigation and fertilization parameters, so that the control panel 20 controls the start of the water pump 2 and the opening and closing degree of the solenoid valve 17. At this time, the water pump 2 generates suction to absorb water through the injection pipe 3, the branch pipe 11 and the water injection pipe 12. When the water flows through the venturi tube 13, the fertilizer injection pipe 14 is affected by the water flow. 4 and the venturi tube 13 generate a great negative pressure, so that the fertilizer in the fertilizer injection pipe 14 is sucked into the branch pipe 11 under the action of the negative pressure, so that the water and fertilizer sucked by the water pump 2 are circulated and pressurized and then discharged through the output pipe 4 and the mixer 5 to the area where fertilization is needed for irrigation and fertilization, and the solenoid valve 17 can control the channel opening of the fertilizer injection pipe 14, and can effectively control the suction amount of fertilizers in different fertilizer injection pipes 14, and carry out integrated irrigation and fertilization according to a certain ratio. It can not only automatically carry out integrated irrigation and fertilization, but also can mix fertilizers of different ratios for effective fertilization, thereby improving the irrigation and fertilization effect on the soil and effectively reducing the workload of the staff.

[0043] Example 2

[0044] The mixed liquid of fertilizer and water discharged through the water pump 2 and the output pipe 4 often needs to be mixed again to make them evenly mixed together. At this time, it is necessary to use a mixer 5 to mix the fertilizer and water before discharging them. When the static mixer 5 is used to mix the fertilizer and water, the water flow is only blocked by fixed blades, which easily leads to poor mixing effect and low mixing efficiency. Although the dynamic mixer 5 can stir and mix the water flow with blades, it often requires an external power system to work, which easily increases the waste of resources. At the same time, only stirring is not conducive to the full mixing of water and fertilizer. Therefore, further improvements are made based on the above embodiments.

[0045] like Figure 3-Figure 12As shown, the partition assembly 6 is slidably arranged inside the mixer 5 and is used to adjust the spatial interval inside the mixer 5. The partition assembly 6 includes a plurality of partitions 601 distributed along the axial direction of the mixer 5 and slidably connected to the mixer 5. The sliding directions of two adjacent partitions 601 are different. An end of each partition 601 close to the output pipe 4 is rotatably connected to an adjusting plate 602. A plurality of circumferentially spaced and through-flow grooves 603 are provided on each partition 601 and the adjusting plate 602. A plurality of guide grooves 604 corresponding to the adjusting plate 602 are provided on the inner circular surface of the mixer 5. A plug rod 605 is fixedly connected to the circumferential side of each adjusting plate 602. Each plug rod 605 extends into the corresponding guide groove 604. The shape of each guide groove 604 is an inclined ring.

[0046] The driving assembly 7 is rotatably disposed in the mixer 5, and is used to drive the partition assembly 6 to slide in the mixer 5. The driving assembly 7 includes an auxiliary tube 701 fixedly connected to the inner wall of the mixer 5. The auxiliary tube 701 is located on a side of the mixer 5 away from the output tube 4. A driving frame 702 is rotatably connected to the inner wall of the auxiliary tube 701. A driving rod 703 consistent with the axis of the mixer 5 is fixedly connected to the driving frame 702. The driving rod 703 passes through multiple partitions 601 in sequence and has multiple driving grooves 704 corresponding to the partitions 601 on its circumferential side. The inner side of each partition 601 is slidably connected to the corresponding driving groove 704 through a driving block 705. Two adjacent driving blocks 705 are staggered so that the sliding directions of the two adjacent driving blocks 705 along the driving groove 704 are opposite.

[0047] The power assembly 8 is rotatably arranged in the mixer 5 and is located in the side of the mixer 5 close to the output pipe 4, and is used to provide power for the drive assembly 7 to rotate. The power assembly 8 includes a mounting tube 801 fixedly connected to the mixer 5, and the mounting tube 801 is located in the side of the mixer 5 close to the output pipe 4. A rotating rod 802 is rotatably connected in the mounting tube 801, and a water wheel 803 is fixedly connected to the rotating rod 802. A main bevel gear 804 is fixedly connected to the circumferential side of the driving frame 702. A rotating shaft 805 is rotatably connected in the auxiliary tube 701, and the rotating shaft 805 is close to the auxiliary tube 701. One end is fixedly connected with an incomplete bevel gear 806 meshing with the main bevel gear 804, the end of the rotating rod 802 and the rotating shaft 805 away from the mounting tube 801 extends out of the mixer 5 and is fixedly connected with a pulley 807, the two pulleys 807 are connected by a synchronous belt 808, and the circumferential side of the mixer 5 is fixedly connected with a protective shell 809 covering the synchronous belt 808 and the pulley 807, a stirring blade 9 fixedly connected to the driving rod 703 is provided between two adjacent partitions 601, and an inclined guide plate 10 is fixedly connected to the side of the mounting tube 801 close to the output pipe 4.

[0048] During use, after the mixed liquid flows from the water pump 2 into the mixer 5 through the output pipe 4, and the guide plate 10 in an inclined state is fixedly connected in the mounting pipe 801, the mixed liquid can be effectively guided to impact the water wheel 803, so that the water wheel 803 drives the rotating rod 802 to rotate along the mixer 5 under the action of the mixed liquid, so that the rotating rod 802 drives the rotating shaft 805 to rotate synchronously through the synchronous belt 808 and the pulley 807, so that the rotating shaft 805 drives the main bevel gear 804 to rotate along the auxiliary pipe 701 through the incomplete bevel gear 806, and the main bevel gear 804 drives the driving frame 702 to rotate along the auxiliary pipe 701, so that the driving frame 702 drives the driving rod 703 to rotate, and the driving rod 703 rotates to drive the driving groove 704 to rotate, and in the process that the driving block 705 closest to the water wheel 803 slides to the vertex of the driving groove 704 close to the water wheel 803, the driving block 705 drives the partition 601 to slide along the mixer 5 in the direction close to the water wheel 803.

[0049] At this time, the next driving block 705 adjacent to the driving block 705 closest to the water wheel 803 drives the corresponding partition 601 to slide along the mixer 5 in the direction away from the water wheel 803, and the next driving block 705 drives the partition 601 to slide along the mixer 5 in the direction close to the water wheel 803, and the partition 601 closest to the driving frame 702 slides in the direction away from the driving frame 702, the distance between the two partitions 601 close to the water wheel 803 increases, and the distance between the two partitions 601 close to the driving frame 702 decreases, so that the partition 601 close to the water wheel 803 drives the adjustment plate 602 to move in the direction of the water wheel 803, and because the guide groove 604 is set in an inclined state, under the action of the guide groove 604, the guide groove 604 is inserted through the rod 605 drives the regulating plate 602 to rotate along the partition 601, and the flow groove 603 on the regulating plate 602 and the partition 601 is gradually misaligned, so that the amount of the mixed liquid flowing through the flow groove 603 is reduced, and the flow velocity of the mixed liquid flowing through the flow groove 603 is increased. After the mixed liquid flows between the two partitions 601, and under the action of the stirring blades 9, turbulence can be better generated, so that the mixed liquid can be fully mixed, and the interval between the two partitions 601 close to the water wheel 803 is increased, so that more mixed liquid can stay between the two partitions 601. At the same time, the driving rod 703 drives the stirring blades 9 to rotate in the mixer 5. The stirring blades 9 can stir the mixed liquid remaining between the two partitions 601, so that the water and fertilizer can be further mixed evenly.

[0050] When the driving block 705 slides to the extreme position along the driving groove 704 toward the water wheel 803, the incomplete bevel gear 806 is no longer meshed with the main bevel gear 804, and the driving rod 703 is no longer rotating, so that the multiple partitions 601 are no longer sliding along the mixer 5, and the stirring blades 9 are no longer rotating. After the mixed liquid passing through the flow groove 603 hits the stationary stirring blades 9, the mixed liquid between the two partitions 601 can generate turbulence better, so that more water and fertilizer in the mixed liquid are fully mixed and evenly mixed. When the incomplete bevel gear 806 is meshed with the main bevel gear 804 again, the driving rod 703 is rotated again. At this time, the partition 601 closest to the water wheel 803 slides in the direction away from the water wheel 803 under the action of the driving block 705 and the driving groove 704, and the adjacent partitions 60 Under the action of the driving block 705 and the driving groove 704, the partition 601 slides toward the direction close to the water wheel 803, so that the interval between the two partitions 601 close to the water wheel 803 gradually decreases, and the partition 601 closest to the driving frame 702 slides toward the driving frame 702, so that the interval between the two partitions 601 close to the driving frame 702 gradually increases. At the same time, the partition 601 and the flow groove 603 on the regulating plate 602 are first gradually and completely connected and then gradually dislocated, so that the flow velocity of the mixed liquid after flowing through the flow groove 603 to the two partitions 601 close to the driving frame 702 increases, and at the same time, the flow distance of the mixed liquid is increased. Under the action of the partition 601 and the regulating plate 602 with the dislocated flow groove 603 of the stirring blade 9, the turbulence can be better generated inside the mixed liquid, so that the water and fertilizer in the mixed liquid are fully mixed.

[0051] When the driving block 705 slides to the extreme position along the driving groove 704 in the direction away from the water wheel 803, the incomplete bevel gear 806 is no longer engaged with the main bevel gear 804, and the driving rod 703 no longer rotates, so that the multiple partitions 601 no longer slide along the mixer 5, and the stirring blades 9 also no longer rotate. At this time, after the mixed liquid passing through the flow groove 603 hits the stationary stirring blades 9, the mixed liquid between the two partitions 601 can generate turbulence and be fully mixed. When the incomplete bevel gear 806 is engaged with the main bevel gear 804 again, the above movement is repeated, so that the distance between the two adjacent partitions 601 changes periodically and alternately, and the flow rate of the mixed liquid passing through the flow groove 603 changes continuously. Under the action of the stirring blades 9, turbulence is better generated in the mixed liquid, so that the water and fertilizer inside it are fully mixed and discharged for integrated irrigation and fertilization.

[0052] In summary, the rotation of the water wheel 803 drives the rotation of the driving rod 703, thereby driving the partition 601 to slide in the mixer 5, so that the interval between two adjacent partitions 601 changes periodically and alternately, and at the same time, the adjusting plate 602 rotates along the partition 601 under the action of the guide groove 604, so that the flow groove 603 on the partition 601 and the adjusting plate 602 is gradually misaligned, so that the flow area is gradually reduced, and the flow rate of the mixed liquid through the flow groove 603 is increased, and under the action of the stirring blades 9, turbulence is generated inside the mixed liquid to fully mix the water and fertilizer. At the same time, the spacing between adjacent partitions 601 changes alternately, which can separate the mixed liquid at different positions in the mixer 5 under the action of the partition 601, thereby dynamically adjusting the flow distance and flow rate of the mixed liquid, and under the action of the generated turbulence, the water and fertilizer are fully mixed, and under the action of the stirring blades 9 that alternate between static and dynamic, the uniformity of the mixing of water and fertilizer can be improved, thereby improving the efficiency and quality of integrated irrigation and fertilization of the soil.
