Description

Technical Field

[0001] The invention relates to the technical field of fertilization equipment, and in particular to a liquid fertilizer precise proportioning alternating irrigation and fertilization equipment and a use method thereof. Background Art

[0002] Fertilization is the act of artificially supplementing the nutrients of plants when the nutrients in the soil cannot provide the nutrients needed for the growth and development of vegetation. The main function of fertilization is to provide plants with nutrients such as nitrogen, phosphorus and potassium, and it is an important measure to ensure the rapid growth of vegetation. Liquid fertilizer is the liquid form of solid fertilizer. With the continuous advancement of science and technology, water-soluble fertilizers are gradually replacing traditional fertilizers. Water-soluble fertilizers can be used in irrigation equipment to achieve water-fertilizer integration and save water, fertilizer and labor.

[0003] In the prior art, watering is required after fertilizing crops to ensure that the root system is moist, which is conducive to the normal growth and development of plants, and promotes the dissolution and release of nutrients in the soil, thereby improving the efficiency of plant absorption of nutrients. However, there is a problem of uneven distribution ratio between water irrigation and liquid fertilizer. Some soils have less irrigation water and high nutrient concentration, while some soils have more irrigation water and low nutrient concentration, which affects the overall growth of crops; and if the irrigation water is added to the liquid fertilizer for dilution before fertilization, the water and fertilizer have a large capacity, resulting in a long mixing time, and uneven mixing is also prone to occur, reducing the efficiency of fertilization and irrigation.

[0020] The invention also discloses a method for using a liquid fertilizer precise proportioning alternating irrigation and fertilization device, comprising the following steps:

[0021] S1: Control the driving motor to operate, so that the travel assembly moves through the frame to the crop fertilization area, and then open the three-way valve at the bottom of the barrel;

[0022] S2: Then the frame cooperates with the traveling assembly to move in the direction of crop planting. When the rotating shaft of the traveling assembly rotates, the input shaft of the gear box is driven to rotate. Through the internal gear transmission of the gear box, the output shaft of the gear box drives the incomplete bevel gear to mesh with the driven bevel gear at the bottom of the rotating rod, so that the driven bevel gear drives the rotating rod to rotate multiple circles during the period of meshing with the incomplete bevel gear. The first drum on the rotating rod reels the first pull rope, and the first pull rope drives the piston to move in the suction pipe through the push rod, so that the two suction pipes each extract the irrigation water or liquid fertilizer in the barrel through the liquid extraction pipe;

[0023] When the rotating rod rotates, the first bevel gear meshes with the second bevel gear on the first rotating rod for transmission, the second bevel gear drives the third bevel gear through the first rotating rod to mesh with the fourth bevel gear on the second rotating rod for transmission, the driven gear on the second rotating rod meshes with the rack plug plate, so that the rack plug plate is inserted downward into the soil, and as the frame moves, the rack plug plate inserted into the soil tilts and moves the soil upward, so that the soil around the crop is loosened;

[0024] When the rotating rod rotates, the second drum reels the second pull rope, so that the second pull rope pulls the end of the nozzle head, and the nozzle head deflects around the connecting rod;

[0025] S3: With the continuous rotation of the rotating shaft, the incomplete bevel gear on the output shaft of the gearbox is no longer meshed with the driven bevel gear for transmission, and the rotating rod is reset and rotated under the action of the second torsion spring, the first drum pays out the first pull rope, and the second drum pays out the second pull rope. After the spray head is not pulled by the second pull rope, it is reset and rotated under the action of the first torsion spring, so that the spray head moves back and forth left and right, and the piston is reset under the pull of the elastic element and pushes the previously extracted liquid into the mixing cylinder, so that the liquid fertilizer in one suction pipe merges with the irrigation water in the other suction pipe, and the rotating rod drives the stirring rod to rotate under the action of the synchronous wheel and the synchronous belt, and the stirring rod drives the stirring blades to stir and mix the liquid in the mixing cylinder, so that the liquid fertilizer and the irrigation water are quantitatively mixed in proportion;

[0026] At this time, the driven gear and the rack plate are meshed in reverse, so that the rack plate moves up and out of the soil;

[0027] S4: Repeat steps S2-S3. After the suction tube draws the liquid again and discharges the liquid into the mixing barrel, the mixed liquid in the original mixing barrel will be squeezed by the liquid newly introduced into the mixing barrel and flow to the nozzle head through the liquid guide tube, and then sprayed on the crops and the ground through the reciprocatingly swinging nozzle head. The liquid dropped on the ground will seep smoothly along the soil cracks after the rack plug is loosened, so that the crop roots and soil can fully absorb the fertilizer.

[0028] Compared with the prior art, the present invention provides a liquid fertilizer precise quantitative ratio alternating irrigation and fertilization equipment and a method of using the same, which has the following beneficial effects:

[0029] 1. The liquid fertilizer precise proportioning alternating irrigation and fertilization equipment and its use method drive the frame along the crop for fertilization and irrigation through the walking component, so that a quantitative and small amount of irrigation water and liquid fertilizer are mixed in proportion, and the diluted liquid fertilizer is used for fertilization work. The mixing time is short and the mixing is uniform, so as to ensure the fertilization and irrigation effect and fertilization and irrigation efficiency.

[0030] 2. The liquid fertilizer precise quantitative proportion alternating irrigation and fertilization equipment and its use method detects the nutrients of farmland soil through a soil nutrient detection instrument, and then controls the stretching of the push rod to shorten the distance between the push rod and the first drum, thereby releasing part of the first pull rope, so that the push rod will not be directly pulled when the first pull rope is subsequently wound up, and the push rod will not be exerted until the first pull rope is fully tightened, so that the push rod drives the piston to slide in the suction pipe, and the sliding distance of the piston in the suction pipe is adjusted to reduce the liquid fertilizer extracted from the suction pipe, so that the subsequently reduced liquid fertilizer is mixed with the irrigation water that is always quantitative, thereby effectively reducing the concentration of the liquid fertilizer, so that the liquid fertilizer is suitable for soil fertilization and irrigation work with different nutrients.

[0031] 3. The liquid fertilizer precise quantitative proportioning alternating irrigation and fertilization equipment and its use method, through the rotating rod under the gear meshing transmission, the second pull rope is wound up by the second drum, so that the second pull rope pulls the end of the nozzle head, and the nozzle head deflects around the connecting rod. When the rotating rod is reset and rotated under the action of the second torsion spring, the second drum pays out the second pull rope, and the nozzle head is not subjected to the tension of the second pull rope and then resets and rotates under the action of the first torsion spring, so that the nozzle head moves back and forth left and right, so that the nozzle head can irrigate and fertilize crops and soil in a large range, thereby improving the efficiency of irrigation and fertilization.

[0032] 4. The liquid fertilizer precise quantitative proportioning alternating irrigation and fertilization equipment and its use method, when the rotating rod rotates, the first bevel gear meshes with the second bevel gear on the first rotating rod for transmission, the second bevel gear drives the third bevel gear to mesh with the fourth bevel gear on the second rotating rod through the first rotating rod for transmission, the driven gear on the second rotating rod meshes with the rack plug plate, so that the rack plug plate is inserted downward into the soil, and as the frame moves, the rack plug plate inserted into the soil is tilted and the soil is pushed upward, so that the soil around the crop is loosened, so that the liquid that falls on the ground later can seep smoothly along the soil cracks after the rack plug plate is loosened, so that the crop roots and the soil can fully absorb the fertilizer, thereby improving the irrigation and fertilization effect.

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0047] Example 1: Reference Figure 1 , Figure 2 , Figure 4 and Figure 7 , a liquid fertilizer precise quantitative ratio alternating irrigation fertilization equipment, comprising a frame 1, a control panel 2 and a soil nutrient detection instrument 201 electrically connected to the control panel 2 are arranged on the frame 1, and also includes:

[0048] A walking assembly, which is fixed on the lower side of the frame 1 and is used to drive the frame 1 to walk;

[0049] Support 3, support 3 is fixed on the upper side of frame 1, and barrels 4 with the same structure are arranged on support 3, one of which is used to store irrigation water, and the other is used to store liquid fertilizer;

[0050] A mixing mechanism according to a ratio, the mixing mechanism according to a ratio comprising two suction components for extracting liquid and a mixing component connected to the two suction components, the two suction components are respectively connected to the two barrels 4 in a one-to-one correspondence; and

[0051] The spray head 5 is arranged at the lower side of the frame 1 and connected to the mixing assembly through a connecting rod 101, and a first torsion spring for driving the spray head 5 to reset and rotate is arranged on the connecting rod 101;

[0052] The frame 1 is also provided with a soil loosening mechanism for assisting the infiltration of liquid.

[0053] Specifically, the frame 1 cooperates with the walking component to move along the crop planting direction. When the walking component is working, the mixing mechanism automatically works according to the ratio, so that a fixed and small amount of irrigation water and liquid fertilizer are mixed in proportion, and the diluted liquid fertilizer is used for fertilization. The mixing time is short and the mixing is uniform, so the fertilization and irrigation effect and fertilization and irrigation efficiency are guaranteed. When the mixing mechanism works according to the ratio, it drives the loosening mechanism to loosen the soil around the crop, so that the waste material that falls on the ground later can infiltrate smoothly along the cracks in the loosened soil, so that the crop roots and soil can fully absorb the fertilizer, thereby improving the irrigation and fertilization effect.

[0054] Example 2: Reference Figure 1 , Figure 2 , Figure 4 and Figure 7 , a liquid fertilizer precise quantitative proportioning alternating irrigation and fertilization equipment, based on Example 1, further, the walking component includes a side plate 6 fixedly mounted on the lower side of the frame 1, a rotating shaft 601 rotatably connected to the side plate 6, a walking wheel 602 arranged on the rotating shaft 601, and a driving motor 603 fixedly mounted on the side plate 6 for driving the rotating shaft 601 to rotate.

[0055] Specifically, when the walking assembly is working, the driving motor 603 is controlled to run, and the output shaft of the driving motor 603 drives the rotating shaft 601 to rotate, so that the rotating shaft 601 drives the walking wheel 602 to roll on the ground, and then the walking assembly drives the frame 1 to move.

[0056] Example 3: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , a liquid fertilizer precise proportioning alternating irrigation and fertilization equipment, based on Example 2, further, the suction component includes a suction pipe 7 fixedly mounted on the frame 1, a piston 701 slidably connected in the suction pipe 7, an elastic element 702 arranged between the inner wall of the suction pipe 7 and the piston 701, a push rod 703 fixedly connected to the piston 701, and a liquid suction pipe 704 and a liquid discharge pipe 705 arranged on the suction pipe 7, the liquid suction pipe 704 and the liquid discharge pipe 705 are both provided with a one-way valve, and a three-way valve connected to the liquid suction pipe 704 is provided at the bottom of the barrel 4.

[0057] Furthermore, the suction assembly also includes a rotating rod 8 rotatably connected to the frame 1, a driven bevel gear 801 arranged at the bottom of the rotating rod 8, a first reel 802 fixedly arranged on the upper side of the rotating rod 8, and a first pull rope 803 wound around the first reel 802, the end of the first pull rope 803 away from the first reel 802 is connected to the push rod 703, and a second torsion spring for driving the rotating rod 8 to reset and rotate is arranged in the frame 1. A gear box 18 is arranged at the bottom of the frame 1 through a support plate, the input shaft of the gear box 18 is connected to the rotating shaft 601, and the output shaft of the gear box 18 is provided with an incomplete bevel gear 181 meshing with the driven bevel gear 801.

[0058] Furthermore, the mixing assembly includes a mixing barrel 10 fixed on the lower side of the frame 1, a stirring rod 1001 rotatably connected to the mixing barrel 10, a stirring blade 1002 arranged on the stirring rod 1001, and a liquid guide tube 1003 connected to the mixing barrel 10, the end of the liquid guide tube 1003 away from the mixing barrel 10 is connected to the nozzle head 5, the end of the discharge pipe 705 away from the suction pipe 7 is connected to the mixing barrel 10, and the top of the stirring rod 1001 and the top of the rotating rod 8 are both provided with synchronous wheels 11, and a synchronous belt is provided between the two synchronous wheels 11.

[0059] Specifically, when the traveling assembly moves to the crop fertilization area through the frame 1, the three-way valve at the bottom of the barrel 4 is opened to connect the three-way valve with the liquid extraction pipe 704. When the rotating shaft 601 of the traveling assembly rotates, the input shaft of the gear box 18 is driven to rotate. Through the internal gear transmission of the gear box 18, the output shaft of the gear box 18 drives the incomplete bevel gear 181 to mesh with the driven bevel gear 801 at the bottom of the rotating rod 8, so that the driven bevel gear 801 drives the rotating rod 8 to rotate multiple circles during the meshing with the incomplete bevel gear 181. The first reel 802 on the rotating rod 8 reels the first pull rope 803, and the first pull rope 803 drives the piston 701 to move in the suction pipe 7 through the push rod 703. The elastic element 702 is compressed. The elastic element 702 can be set as a spring, so that the two suction pipes 7 each extract the irrigation water or liquid fertilizer in the barrel 4 through the liquid extraction pipe 704.

[0060] As the rotating shaft 601 continues to rotate, the incomplete bevel gear 181 on the output shaft of the gear box 18 is no longer meshed with the driven bevel gear 801 for transmission, and the rotating rod 8 is reset and rotated under the action of the second torsion spring, and the first reel 802 pays off the first pull rope 803. After the spray head 5 is not pulled by the second pull rope 121, it is reset and rotated under the action of the first torsion spring, so that the spray head 5 moves back and forth left and right, and the piston 701 is reset under the pull of the elastic element 702 and pushes the previously extracted liquid into the mixing barrel 10, so that the liquid fertilizer in one suction pipe 7 merges with the irrigation water in the other suction pipe 7, and the rotating rod 8 drives the stirring rod 1001 to rotate under the action of the synchronous wheel 11 and the synchronous belt, and the stirring rod 1001 drives the stirring blade 1002 to stir and mix the liquid in the mixing barrel 10, so that the liquid fertilizer and the irrigation water are quantitatively mixed in proportion;

[0061] After the suction tube 7 draws the liquid again and discharges the liquid into the mixing cylinder 10, the mixed liquid originally in the mixing cylinder 10 will be squeezed by the liquid newly introduced into the mixing cylinder 10 and flow to the nozzle head 5 through the liquid guide tube 1003, and sprayed on the crops and the ground through the nozzle head 5; it should be noted that a one-way valve is also provided on the liquid guide tube 1003.

[0062] Example 4: Reference Figure 4 , Figure 5 and Figure 7 , a liquid fertilizer precise quantitative proportion alternating irrigation and fertilization equipment, based on Example 3, further, the push rod 703 is set as an electric telescopic rod, the frame 1 is fixed with a first elastic telescopic rod 9 through a support plate, and the end of the first elastic telescopic rod 9 is provided with a tensioning ring 901 slidably connected to the first pull rope 803.

[0063] Specifically, the soil nutrient detection instrument 201 is used to detect the nutrients in the farmland soil, and then the push rod 703 is controlled to stretch, so that the distance between the push rod 703 and the first reel 802 is shortened, thereby partially releasing the first pull rope 803, so that the push rod 703 will not be directly pulled when the first pull rope 803 is subsequently wound up. Only after the first pull rope 803 is fully tightened will the push rod 703 be forced, so that the push rod 703 drives the piston 701 to slide in the suction pipe 7, and the piston 701 in the suction pipe 7 is adjusted. The sliding distance reduces the liquid fertilizer extracted from the suction tube 7, so that the subsequently reduced liquid fertilizer is mixed with the always quantitative irrigation water, thereby effectively reducing the concentration of the liquid fertilizer, making the liquid fertilizer suitable for soil fertilization and irrigation work with different nutrients; it should be noted that the first elastic telescopic rod 9 uses the tensioning ring 901 to tension the first pull rope 803 to prevent the first pull rope 803 from being no longer tightened and falling off the first reel 802 when the push rod 703 becomes longer, thereby affecting the normal operation of the subsequent suction components.

[0064] Example 5: Reference Figure 1, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , a liquid fertilizer precise proportioning alternating irrigation and fertilization equipment, based on Example 4, further, a second drum 12 is provided on the rotating rod 8, a second pull rope 121 is wound around the second drum 12, and the end of the second pull rope 121 away from the second drum 12 is connected to the sprinkler head 5.

[0065] Specifically, when the output shaft of the gear box 18 drives the incomplete bevel gear 181 to mesh with the driven bevel gear 801 at the bottom of the rotating rod 8, the rotating rod 8 reels the second pull rope 121 through the second drum 12, so that the second pull rope 121 pulls the end of the nozzle head 5, and the nozzle head 5 deflects around the connecting rod 101; when the incomplete bevel gear 181 on the output shaft of the gear box 18 is no longer meshed with the driven bevel gear 801, the rotating rod 8 resets and rotates under the action of the second torsion spring, and the second drum 12 pays off the second pull rope 121. After the nozzle head 5 is not pulled by the second pull rope 121, it resets and rotates under the action of the first torsion spring, so that the nozzle head 5 moves back and forth left and right. The reciprocatingly swinging nozzle head 5 sprays fertilizer on crops and the ground. The nozzle head 5 can irrigate and fertilize crops and soil over a large range, thereby improving the efficiency of irrigation and fertilization.

[0066] Example 6: Reference Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8 , Fig.10 and Fig.11 , a liquid fertilizer precise quantitative ratio alternating irrigation and fertilization equipment, based on Example 5, further, the loosening mechanism includes a first rotating rod 13 and a second rotating rod 14 rotatably connected to the lower side of the frame 1 through a support plate, and the two ends of the first rotating rod 13 are respectively provided with a second bevel gear 131 and a third bevel gear 132, the rotating rod 8 is provided with a first bevel gear 804 meshing with the second bevel gear 131, the second rotating rod 14 is provided with a fourth bevel gear 141 meshing with the third bevel gear 132, and the fourth bevel gear 141 is provided with a driven gear 142, and a rack plug plate 15 meshing with the driven gear 142 is slidably connected in the frame 1, and a second elastic telescopic rod 16 is movably provided between the top of the rack plug plate 15 and the barrel 4.

[0067] Furthermore, a groove 17 for the rack inserting plate 15 to move is provided on the frame 1 , a guide rod 171 is fixedly provided at the bottom of the groove 17 via a connecting plate, and a movable groove 151 matching with the guide rod 171 is provided on the rack inserting plate 15 .

[0068] Specifically, when the output shaft of the gear box 18 drives the incomplete bevel gear 181 to mesh with the driven bevel gear 801 at the bottom of the rotating rod 8, the first bevel gear 804 on the outer side of the rotating rod 8 meshes with the second bevel gear 131 on the first rotating rod 13, and the second bevel gear 131 drives the third bevel gear 132 to mesh with the fourth bevel gear 141 on the second rotating rod 14 through the first rotating rod 13, and the driven gear 142 on the second rotating rod 14 meshes with the rack plug plate 15, so that the rack plug plate 15 Inserted downward into the soil, as the frame 1 moves forward, the rack plate 15 inserted into the soil tilts and pushes the soil upward to loosen the soil around the crop. When the incomplete bevel gear 181 on the output shaft of the gear box 18 is no longer meshed with the driven bevel gear 801 for transmission, the driven gear 142 meshes with the rack plate 15 in the opposite direction, causing the rack plate 15 to move upward and out of the soil. The liquid dropped on the ground seeps smoothly along the cracks in the soil after the rack plate 15 is loosened, allowing the crop roots and the soil to fully absorb the fertilizer.

[0069] The invention also discloses a method for using a liquid fertilizer precise proportioning alternating irrigation and fertilization device, comprising the following steps:

[0070] S1: Control the driving motor 603 to operate, so that the traveling assembly moves to the crop fertilization area through the frame 1, and then open the three-way valve at the bottom of the barrel 4;

[0071] S2: Then the frame 1 is made to cooperate with the traveling assembly to move along the crop planting direction. When the rotating shaft 601 of the traveling assembly rotates, the input shaft of the gear box 18 is driven to rotate. Through the internal gear transmission of the gear box 18, the output shaft of the gear box 18 drives the incomplete bevel gear 181 to mesh with the driven bevel gear 801 at the bottom of the rotating rod 8, so that the driven bevel gear 801 drives the rotating rod 8 to rotate multiple circles during the period of meshing with the incomplete bevel gear 181. The first reel 802 on the rotating rod 8 reels the first pull rope 803. The first pull rope 803 drives the piston 701 to move in the suction pipe 7 through the push rod 703, so that the two suction pipes 7 each extract the irrigation water or liquid fertilizer in the barrel 4 through the liquid extraction pipe 704;

[0072] When the rotating rod 8 rotates, the first bevel gear 804 meshes with the second bevel gear 131 on the first rotating rod 13 for transmission, and the second bevel gear 131 drives the third bevel gear 132 to mesh with the fourth bevel gear 141 on the second rotating rod 14 through the first rotating rod 13 for transmission, and the driven gear 142 on the second rotating rod 14 meshes with the rack plug 15, so that the rack plug 15 is inserted downward into the soil. As the frame 1 moves forward, the rack plug 15 inserted into the soil is tilted and the soil is moved upward, so that the soil around the crop is loosened;

[0073] When the rotating rod 8 rotates, the second drum 12 reels the second pull rope 121, so that the second pull rope 121 pulls the end of the spray head 5, and the spray head 5 deflects around the connecting rod 101;

[0074] S3: With the continuous rotation of the rotating shaft 601, the incomplete bevel gear 181 on the output shaft of the gear box 18 is no longer meshed with the driven bevel gear 801 for transmission, and the rotating rod 8 is reset and rotated under the action of the second torsion spring, the first reel 802 pays off the first pull rope 803, and the second reel 12 pays off the second pull rope 121. After the spray head 5 is not pulled by the second pull rope 121, it is reset and rotated under the action of the first torsion spring, so that the spray head 5 moves back and forth left and right, and the piston 701 is reset under the pull of the elastic element 702 and pushes the previously extracted liquid into the mixing barrel 10, so that the liquid fertilizer in one suction pipe 7 merges with the irrigation water in the other suction pipe 7, and the rotating rod 8 drives the stirring rod 1001 to rotate under the action of the synchronous wheel 11 and the synchronous belt, and the stirring rod 1001 drives the stirring blade 1002 to stir and mix the liquid in the mixing barrel 10, so that the liquid fertilizer and the irrigation water are quantitatively mixed in proportion;

[0075] At this time, the driven gear 142 and the rack plate 15 are reversely meshed, so that the rack plate 15 moves upward and out of the soil;

[0076] S4: Repeat steps S2-S3. After the suction tube 7 draws the liquid again and discharges the liquid into the mixing barrel 10, the mixed liquid in the original mixing barrel 10 will be squeezed by the liquid newly introduced into the mixing barrel 10 and flow to the nozzle head 5 through the liquid guide tube 1003, and sprayed on the crops and the ground through the reciprocatingly swinging nozzle head 5. The liquid dropped on the ground will seep smoothly along the soil cracks after the rack plug plate 15 is loosened, so that the crop roots and the soil can fully absorb the fertilizer.
