Description

Technical Field

[0001] This application relates to the technical field of agricultural irrigation, and particularly to a drip irrigation water-fertilizer ratio device. Background Art

[0002] In the field of agricultural production, especially in large-scale farmland operations, irrigation and fertilization are key links to ensure the good growth of crops and achieve high yields. In terms of crop fertilization, mixing fertilizers with water to form water-fertilizer is a common way to supply nutrients to crops.

[0003] Traditional water-fertilizer irrigation is to manually spray fertilizers onto the crop areas in the farmland, and the spraying amount and time are manually controlled to meet the nutrient supply, or directly put fertilizers into the irrigation system to mix with water to form water-fertilizer, and then the water-fertilizer is irrigated into the farmland through the irrigation system.

[0004] In view of the above related technologies, due to the large area of farmland, manual operation requires a large amount of labor and time costs, and it is difficult for manual labor to ensure the uniform distribution of fertilizers throughout the farmland, and it is easy to have the situation of excessive or insufficient local fertilization. And the method of directly putting fertilizers into the irrigation system to mix with water to form water-fertilizer for irrigation, although it saves manpower to a certain extent, the feeding process still depends on manual experience to control, and it is difficult to accurately control the feeding amount of fertilizers, and thus it is impossible to ensure the concentration stability of water-fertilizer. Summary of the Invention

The stirring member allows the fertilizer to be fully dissolved and evenly mixed in the dissolution tank to form a fertilizer solution. The knocking assembly helps the fertilizer in the metering tank to fall smoothly, avoiding blockage and maintaining the continuous operation of the equipment, while the irrigation assembly realizes the accurate irrigation of the fertilizer solution to the farmland. Overall, the equipment realizes the automated process from fertilizer treatment, metering and proportioning, dissolution and mixing to irrigation, which not only improves the fertilization accuracy, meets the growth requirements of crops at different stages, but also simplifies the operation, saves labor, and improves the efficiency and quality of large-area farmland irrigation and fertilization.

[0018] Optionally, the metering part includes:

[0019] A slide plate, which is slidably installed in the metering tank, the periphery of the slide plate abuts against the side wall of the metering tank, and a material discharging port is formed on the slide plate;

[0020] A discharging plate, which is hinged to the material discharging port and is adapted to the material discharging port;

[0021] A torsion spring, the two ends of which are respectively fixedly connected to the discharging plate and the slide plate;

[0022] A first airbag, which is fixedly installed in the metering tank, is located below the slide plate and abuts against the slide plate;

[0023] A telescopic plate, which is arranged at the connection between the dissolution tank and the metering tank. The telescopic plate includes a fixed box and a sliding plate. The fixed box is fixedly installed at the connection between the dissolution tank and the metering tank. The sliding plate is slidably arranged in the fixed box. The sliding plate divides the inner part of the fixed box into a plate chamber and a non-plate chamber. The plate chamber of the fixed box is communicated with the first airbag;

[0024] The first spring, and the first spring is installed in the plate - less cavity of the fixed box.

[0025] By adopting the above - mentioned technical solution, the drip irrigation fertilizer ratio device can achieve the control of the fertilizer feeding amount. During the feeding process, under the action of the gravity of the fertilizer, the slide plate slides downward, the first airbag is squeezed, the first airbag is communicated with the plate - having cavity of the fixed box, and under the pressure of the slide plate, the gas enters the plate - having cavity of the fixed box, and then pushes the sliding plate to retract into the fixed box, the first spring is compressed, the dissolving box and the metering box are communicated. As the feeding amount gradually increases until it reaches the preset feeding amount, the sliding plate retracts completely. At this time, under the action of the control part, the falling path of the fertilizer is cut off, so as to accurately achieve quantitative feeding and reach the quantitative effect.

[0026] Optionally, the control part includes:

[0027] The second airbag, the second airbag is fixedly installed in the plate - less cavity of the fixed box and is located at one end far from the sliding plate;

[0028] The first telescopic rod, the first telescopic rod is fixedly installed on the slide plate, and the rod - having cavity of the first telescopic rod is communicated with the second airbag;

[0030] The stop block, the stop block is fixedly installed on the first telescopic rod, a guiding inclined surface is arranged on the stop block, and the stop block abuts against the feeding plate;

[0031] The touch switch, the touch switch is fixedly installed in the rod - less cavity of the first telescopic rod.

[0032] By adopting the above - mentioned technical solution, the second airbag, as a key air - pressure sensing and conduction element, is squeezed in a specific state where the sliding plate of the telescopic plate retracts, triggering an air - pressure change to cause the first telescopic rod to retract, thereby driving the stop block to disengage from the abutment with the feeding plate. The chain reaction of this action enables the feeding plate to be opened in a timely manner according to the gravity of the fertilizer, realizing an automatic feeding trigger mechanism. The setting of the touch switch provides accurate control feedback. Once the first telescopic rod reaches the predetermined position, it is triggered to timely instruct the crushing and feeding component to stop feeding, effectively preventing excessive fertilizer feeding. This design not only greatly improves the control accuracy of the fertilizer feeding amount, reduces the error caused by human factors, but also enables the entire drip irrigation fertilizer ratio device to operate stably according to the preset parameters, continuously and stably supply the fertilizer solution with appropriate concentration and dosage for crops, and realizes the function of accurately controlling the fertilizer feeding amount.

[0033] Optionally, the knocking component includes:

[0034] A second telescopic rod, which is fixedly installed on the metering tank.

[0038] A contact switch, which is fixedly installed in the rod chamber of the second telescopic rod and is electrically connected to the knocking motor.

[0039] By adopting the above technical solution, when the first telescopic rod retracts to cause the blanking plate to rotate and discharge materials, the associated second telescopic rod extends and triggers the contact switch, and then the knocking motor is started to drive the cam to rotate. At this time, the blanking plate rebounds under the action of the torsion spring and contacts the cam, and the continuous rotation of the cam applies a rhythmic knocking force to the blanking plate, realizing automatic knocking triggering. The knocking action effectively prevents the fertilizer from caking and blocking in the metering tank, ensures that the fertilizer can fall smoothly and evenly, and effectively solves the problem of caking or blocking of the fertilizer in the metering tank.

[0040] Optionally, the crushing and feeding assembly includes:

[0041] A screw conveyor, the two ends of which are respectively communicated with the fertilizer bin and the metering tank;

[0042] A feeding motor, which is connected to the rotating shaft of the screw conveyor and is electrically connected to the touch switch;

[0044] A rotating rod, which penetrates through the bottom of the fertilizer bin;

[0045] A second bevel gear, which is coaxially and fixedly installed on the rotating rod and meshes with the first bevel gear;

[0046] Crushing blades, which are arranged in the fertilizer bin and are fixedly installed on the rotating rod.

[0047] By adopting the above technical solution, the screw conveyor can evenly convey the fertilizer in the fertilizer bin to the metering box, avoiding the blockage of the pipeline by large-particle fertilizers. The feeding motor drives the screw conveyor to operate, ensuring the continuous supply of fertilizers. The cooperation of the first bevel gear and the second bevel gear enables the crushing blades on the rotating rod to crush large-particle fertilizers during the conveying process, further improving the uniformity and dissolution rate of fertilizers, achieving the uniform crushing and efficient conveying of fertilizers, and ensuring the quality of the water-fertilizer mixture.

[0048] Optionally, the stirring member includes:

[0049] A stirring motor, the fixed end of which is fixedly installed on the dissolution tank;

[0050] A rotating shaft, which is rotatably installed on the dissolution tank, and one end of the rotating shaft is coaxially and fixedly connected to the output end of the stirring motor;

[0051] Stirring fan blades, which are fixedly installed on the rotating shaft.

[0052] By adopting the above technical solution, the stirring motor drives the rotating shaft to rotate, driving the stirring fan blades to fully stir the water-fertilizer mixture in the dissolution tank, ensuring the uniform mixing of water and fertilizers, improving the mixing effect and stability, thereby enhancing the irrigation effect and promoting the absorption of nutrients by crops.

[0053] Optionally, the irrigation assembly includes:

[0054] A water inlet pipe, one end of which is communicated with an external water source, and the other end of which is communicated with the dissolution tank;

The first valve can accurately control the amount of water flowing into the dissolution tank, facilitating the adjustment of the fertilizer solution concentration and ensuring the accuracy of the water-fertilizer ratio. The liquid outlet pipe leads out the prepared fertilizer solution from the dissolution tank. The second valve can effectively control the output flow rate and timing of the fertilizer solution. When irrigating with water, the second valve is closed, and the external water source flows through the main pipe into the branch pipes and is used for farmland irrigation through the drip holes. When irrigating with water-fertilizer, the second valve is opened, and the prepared water-fertilizer is evenly dispersed over a large area of farmland through the main pipe, and uniform fertilization is achieved by using the irrigation device, providing a continuous and stable nutrient supply for crop growth.

[0061] Optionally, a depth sensor is installed in the dissolution tank, and both the first valve and the second valve are electrically connected to the depth sensor.

[0077] The following will further elaborate on this application Figures 1-5 in conjunction with the accompanying drawings.

[0078] The embodiment of this application discloses a drip irrigation water-fertilizer ratio device.

[0079] Referring to Figure 1 and Figure 2 , the drip irrigation water-fertilizer ratio device includes a fertilizer bin 1, a metering tank 2, a dissolution tank 3, a crushing and feeding assembly 4, a metering mechanism 5, a stirring member 6, a knocking assembly 7, and an irrigation assembly 8. Water-soluble fertilizer is placed in the fertilizer bin 1. The crushing and feeding assembly 4 is installed on the fertilizer bin 1 and is used to cut large pieces of fertilizer into small pieces and convey them into the metering tank 2. The metering tank 2 is located below the crushing and feeding assembly 4, the dissolution tank 3 is located below the metering tank 2, and the dissolution tank 3 is communicated with the fertilizer bin 1. The metering mechanism 5 is installed on the metering tank 2 and is used to control the feeding amount of the fertilizer. The metering mechanism 5 includes a metering part 51 and a control part 52. The metering part 51 is used to control the material discharge amount, and the control part 52 is used to control the metering part 51. The stirring member 6 is installed in the dissolution tank 3 and is used to fully mix the water and the fertilizer. The knocking assembly 7 is installed on the metering tank 2 and is used to make the fertilizer in the metering tank 2 fall. The irrigation assembly 8 is connected to the dissolution tank 3 and is used to irrigate the prepared water-fertilizer into the farmland.

[0080] When using this drip irrigation water-fertilizer ratio device, first place the water-soluble fertilizer in the fertilizer bin 1, start the crushing and feeding assembly 4, which will cut the large pieces of fertilizer into small pieces and convey them to the metering tank 2. Then, set the material discharge amount through the metering part 51 of the metering mechanism 5, and the control part 52 regulates the operation of the metering part 51 to make the fertilizer fall from the metering tank 2 into the dissolution tank 3 according to the preset amount. The fertilizer falling into the dissolution tank 3 is fully mixed with water under the action of the stirring member 6 to form a uniform fertilizer solution. During this period, the knocking assembly 7 will play a role to promote the smooth falling of the fertilizer. Finally, the prepared fertilizer solution is accurately irrigated into the farmland through the irrigation assembly 8, thus realizing a complete process from fertilizer pretreatment, precise metering, full dissolution to effective irrigation, without manual preparation of water-fertilizer, and saving the labor intensity of workers.

[0081] Referring to Figure 1 and Figure 2, the crushing and feeding assembly 4 includes a screw conveyor 41, a feeding motor 42, a first bevel gear 43, a rotating rod 44, a second bevel gear 45, and crushing blades 46. One end of the screw conveyor 41 communicates with the bottom of the fertilizer bin 1, and the other end is arranged at the top of the metering tank 2. The metering tank 2 is open at the upper end. The feeding motor 42 is coaxially and fixedly connected to the rotating shaft of the screw conveyor 41. The first bevel gear 43 is coaxially and fixedly installed on the rotating shaft of the screw conveyor 41. The rotating rod 44 vertically penetrates through the bottom of the fertilizer bin 1. The second bevel gear 45 is coaxially and fixedly installed on the rotating rod 44. The second bevel gear 45 meshes with the first bevel gear 43. The crushing blades 46 are arranged in the fertilizer bin 1 and are fixedly installed on the rotating rod 44.

[0082] When the equipment is running, the feeding motor 42 starts, driving the rotation of the rotating shaft of the screw conveyor 41, so that the screw conveyor 41 starts to work. At the same time, the first bevel gear 43 coaxially fixed to the rotating shaft of the screw conveyor 41 rotates accordingly. Since the first bevel gear 43 meshes with the second bevel gear 45, the rotation of the first bevel gear 43 drives the second bevel gear 45 to rotate, and then the rotating rod 44 rotates at the bottom of the fertilizer bin 1. The crushing blades 46 fixed on the rotating rod 44 rotate at a high speed in the fertilizer bin 1. At this time, the agglomerated fertilizer in the fertilizer bin 1 is broken into smaller pieces under the action of the crushing blades 46, and then is conveyed to the top of the metering tank 2 by the screw conveyor 41 and falls into the metering tank 2 through the upper opening of the metering tank 2, completing the process from fertilizer crushing to conveying to the metering tank 2, and preparing for subsequent accurate quantitative batching.

[0083] Refer to Figure 2 , Figure 3 and Figure 5, the metering part 51 includes a slide plate 511, a blanking plate 512, a torsion spring 513, a first airbag 514, a telescopic plate 515 and a first spring 516. The slide plate 511 is slidably installed in the metering tank 2, the periphery of the slide plate 511 abuts against the side wall of the metering tank 2, a square blanking port is formed on the slide plate 511, one side of the blanking plate 512 is hinged to the blanking port, the blanking plate 512 is adapted to the size of the blanking port, the two ends of the torsion spring 513 are respectively fixedly connected to the blanking plate 512 and the slide plate 511, the first airbag 514 is fixedly installed in the metering tank 2, the first airbag 514 is located below the slide plate 511 and abuts against the slide plate 511, and the first airbag 514 does not contact the blanking plate 512. The telescopic plate 515 is horizontally arranged, and the telescopic plate 515 is arranged at the communication part between the dissolving tank 3 and the metering tank 2. The telescopic plate 515 includes a fixed box 5151 and a sliding plate 5152. The fixed box 5151 is fixedly installed at the communication part between the dissolving tank 3 and the metering tank 2. The inside of the fixed box 5151 is a cavity. The sliding plate 5152 is slidably arranged in the fixed box 5151. The cross section of the sliding plate 5152 is a T-shaped structure. The sliding plate 5152 divides the inside of the fixed box 5151 into a plate chamber and a non-plate chamber. When the sliding plate 5152 extends, the dissolving tank 3 and the metering tank 2 are separated by the sliding plate 5152. When the sliding plate 5152 retracts, the dissolving tank 3 and the metering tank 2 are communicated. The plate chamber of the fixed box 5151 is communicated with the first airbag 514, and the first spring 516 is installed in the non-plate chamber of the fixed box 5151.

[0084] Referring to Figure 2 , Figure 3 and Figure 4 , the control part 52 includes a second airbag 521, a first telescopic rod 522, a second spring 523, a stop block 524 and a touch switch 525. The second airbag 521 is fixedly installed in the non-plate chamber of the fixed box 5151 and is located at one end away from the sliding plate 5152. The first telescopic rod 522 is horizontally arranged. The first telescopic rod 522 is fixedly installed on the slide plate 511. The rod chamber of the first telescopic rod 522 is communicated with the second airbag 521. The second spring 523 is installed in the rodless chamber of the first telescopic rod 522. The stop block 524 is fixedly installed at the movable end of the first telescopic rod 522. A guiding inclined surface is arranged on the stop block 524. The stop block 524 abuts against the blanking plate 512 and supports the blanking plate 512. The touch switch 525 is fixedly installed in the rodless chamber of the first telescopic rod 522. The touch switch 525 is electrically connected to the feeding motor 42.

[0085] At the initial stage of the equipment operation, the slide plate 511 slides downward under the action of the gravity of the fertilizer, squeezing the first airbag 514 below, and the gas enters the plate chamber of the fixed box 5151, causing the sliding plate 5152 to retract, and the first spring 516 is compressed. As the feeding increases, when the preset feeding amount is reached, the sliding plate 5152 completely retracts into the fixed box 5151. At this time, the first telescopic rod 522 also moves because it is connected to the slide plate 511. Affected by the change of the non-plate chamber of the fixed box 5151, the gas enters the rod chamber of the first telescopic rod 522, the first telescopic rod 522 retracts, and the second spring 523 is compressed. The stop block 524 retracts accordingly and no longer supports the feeding plate 512. The feeding plate 512 rotates around the hinge under the gravity of the fertilizer, and the fertilizer falls into the metering box 2.

[0086] At the same time, when the first telescopic rod 522 reaches the predetermined position, the touch switch 525 is triggered, which can control the feeding motor 42 to stop running and stop conveying the fertilizer, so as to accurately control the fertilizer feeding amount and ensure the accuracy and stability of the whole water-fertilizer ratio process to meet the precise fertilization requirements of farmland irrigation.

[0087] Refer to Figure 1 and Figure 2 As shown in [relevant figure numbers], the stirring member 6 includes a stirring motor 61, a rotating shaft 62 and stirring fan blades 63. The fixed end of the stirring motor 61 is fixedly installed at the bottom of the dissolving tank 3. The rotating shaft 62 is arranged vertically. The rotating shaft 62 is rotatably installed on the dissolving tank 3. One end of the rotating shaft 62 is coaxially and fixedly connected to the output end of the stirring motor 61. There are multiple stirring fan blades 63, and the stirring fan blades 63 are fixedly installed on the rotating shaft 62.

[0088] When the fertilizer falls into the dissolving tank 3, the stirring motor 61 is started, and its output end drives the rotating shaft 62 to start rotating. The multiple stirring fan blades 63 on the rotating shaft 62 rotate synchronously, forming a strong water flow disturbance in the dissolving tank 3. Under the action of the stirring fan blades 63, the water flow circulates rapidly, prompting the fertilizer particles to be quickly dispersed and dissolved in the water, forming a uniform fertilizer solution, which ensures the uniformity and stability of the fertilizer solution concentration during the fertilization process.

[0089] Refer to Figure 2 and Figure 3, the knocking component 7 includes a second telescopic rod 71, a third spring 72, a cam 73, a knocking motor 74 and a contact switch 75. The second telescopic rod 71 is horizontally arranged and fixedly installed on the metering tank 2. The second telescopic rod 71 is located on the side of the blanking plate 512 away from the hinge, and the second telescopic rod 71 is located below the blanking plate 512. The rodless cavity of the second telescopic rod 71 is communicated with the rodless cavity of the first telescopic rod 522. The third spring 72 is installed in the rod cavity of the second telescopic rod 71. The cam 73 is rotatably installed at the movable end of the second telescopic rod 71. When the stop block 524 no longer supports the blanking plate 512 and the second telescopic rod 71 extends, the cam 73 contacts the blanking plate 512. When the second telescopic rod 71 retracts, there is no contact point between the cam 73 and the blanking plate 512. The fixed end of the knocking motor 74 is fixedly installed at the movable end of the second telescopic rod 71, and the output end of the knocking motor 74 is coaxially and fixedly connected with the cam 73. The contact switch 75 is fixedly installed in the rod cavity of the second telescopic rod 71, and the contact switch 75 is electrically connected with the knocking motor 74.

[0090] During the operation of the equipment, when the first telescopic rod 522 retracts, the blanking plate 512 rotates downward around the hinge under the action of gravity, and at the same time drives the second telescopic rod 71 to extend. When the second telescopic rod 71 extends, it will trigger the contact switch 75, thereby starting the knocking motor 74. The knocking motor 74 drives the cam 73 to rotate. At this time, the cam 73 is located above the blanking plate 512. When the cam 73 rotates, its convex part will contact the blanking plate 512 and generate a knocking force. Under the action of the torsion spring 513, the blanking plate 512 will have a rebounding action and continuously collide with the continuously rotating cam 73, so as to realize the rapid knocking of the blanking plate 512, which can effectively shake off the fertilizer that may adhere or agglomerate inside the blanking plate 512 and the metering tank 2, make the fertilizer fall smoothly, and ensure the continuity and stability of the fertilizer delivery.

[0091] Refer to Figure 1 and Figure 2 , the irrigation component 8 includes a water inlet pipe 81, a first valve 82, a liquid outlet pipe 83, a second valve 84, a main pipe 85 and a branch pipe 86.

The first valve 82 is installed on the water inlet pipe 81. One end of the liquid outlet pipe 83 is communicated with the dissolution tank 3. The second valve 84 is installed on the liquid outlet pipe 83. One end of the main pipe 85 is connected with an external water source, and the main pipe 85 is communicated with the end of the liquid outlet pipe 83 away from the dissolution tank 3. A plurality of branch pipes 86 are arranged at intervals and are all communicated with the main pipe 85. Drip irrigation holes are arranged at intervals on the branch pipes 86. A depth sensor 9 is installed in the dissolution tank 3, and both the first valve 82 and the second valve 84 are electrically connected with the depth sensor 9.

[0092] When performing irrigation operations, first, the depth sensor 9 detects the depth information of the fertilizer solution in the dissolution tank 3 and transmits the data to the first valve 82 and the second valve 84 that are electrically connected to it. According to the fertilizer solution depth data, the first valve 82 automatically adjusts its opening degree to control the amount of water flowing into the dissolution tank 3 from the external water source through the water inlet pipe 81, so as to maintain the stability and suitability of the fertilizer solution concentration in the dissolution tank 3. When it is necessary to irrigate the fertilizer solution into the farmland, the second valve 84 opens according to the signal of the depth sensor 9, and the fertilizer solution flows out of the dissolution tank 3 through the liquid outlet pipe 83, is distributed to multiple branch pipes 86 through the main pipe 85, and finally, the fertilizer solution slowly and evenly drips into the farmland from the drip irrigation holes on the branch pipes 86, accurately providing water and nutrients for the roots of the crops. During the whole process, the first valve 82 and the second valve 84 are automatically controlled based on the feedback of the depth sensor 9, ensuring the accuracy and stability of the irrigation flow rate and the fertilizer solution concentration, meeting the growth needs of the crops, avoiding the waste of water resources and fertilizers, effectively improving the efficiency and quality of irrigation and fertilization, and promoting the refined management of agricultural production.

[0093] The implementation principle of a drip irrigation water-fertilizer ratio equipment in an embodiment of this application is as follows: First, place water-soluble fertilizers in the fertilizer bin 1, start the crushing and feeding assembly 4, the feeding motor 42 drives the spiral conveyor 41 to rotate, and the connected bevel gear transmission structure causes the rotating rod 44 to rotate, driving the crushing blades 46 to crush the fertilizers in the fertilizer bin 1. The crushed fertilizers are transported to the metering tank 2 by the spiral conveyor 41.

[0094] Next, the metering mechanism 5 starts to function. In the metering tank 2, the slide plate 511 slides downward under the influence of the gravity of the fertilizer, squeezing the first airbag 514, causing the sliding plate 5152 to retract. At the same time, the control unit 52, based on the action changes of components such as the slide plate 511, precisely controls the opening and closing of the blanking plate 512 through the air pressure conduction between components such as the second airbag 521 and the first telescopic rod 522, as well as the stretching, blocking, etc. of the components, so as to accurately control the amount of fertilizer falling from the metering tank 2 into the dissolution tank 3. When the preset blanking amount is reached, the relevant components trigger actions to stop blanking, realizing accurate quantitative feeding.

[0095] Then, for the fertilizers falling into the dissolution tank 3, during this period, the knocking assembly 7 will intervene. Through the cooperation of components such as the second telescopic rod 71 and the cam 73, the knocking motor 74 is triggered to work, and the cam 73 rotates to knock the blanking plate 512 to ensure that the fertilizers smoothly fall into the metering tank 2 and enter the dissolution tank 3. Under the action of the stirring member 6, the fertilizers are fully mixed with water to form a uniform fertilizer solution.

[0096] Finally, according to the information fed back by the depth sensor 9 in the dissolution tank 3, the irrigation assembly 8 automatically adjusts the opening degrees of the first valve 82 and the second valve 84. The prepared fertilizer solution is precisely and evenly irrigated into the farmland through the liquid outlet pipe 83, the main pipe 85, the branch pipe 86 and the drip irrigation holes on the branch pipe 86. In the whole process, each component cooperates with each other to realize the full-process automatic operation from fertilizer pretreatment, precise quantification, sufficient dissolution to effective irrigation, ensuring that the farmland obtains scientific, reasonable and precise water and fertilizer supply, and improving the efficiency, quality and resource utilization efficiency of agricultural production.

[0097] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
