Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, and more particularly to an agricultural rolling alternating irrigation water and fertilizer device, and a method for using the agricultural rolling alternating irrigation water and fertilizer device. Background Technology

[0002] Fertilizer and water integration is a new agricultural technology that combines irrigation and fertilization. It involves preparing soluble solid or liquid fertilizers into a fertilizer solution based on soil nutrient content and crop nutrient requirements, then mixing it with irrigation water. Through a controllable pipeline system, such as drip irrigation or sprinkler irrigation equipment, the water and fertilizer are fully integrated and then precisely delivered to the crop root zone through pipelines and drippers in proportion, achieving synchronous and efficient supply of water and nutrients and improving utilization efficiency.

[0003] While existing irrigation equipment can achieve precise water and fertilizer ratios at the source, in practice, it is usually used to cover a large area with multiple pipes for uniform irrigation and fertilization. However, crops in different regions have significantly different water and fertilizer requirements due to differences in varieties, growth stages, and soil conditions. If the same ratio is used, it is easy to cause problems such as seedling burn and root rot in some areas due to nutrient overload, while other areas suffer from crop growth due to insufficient nutrients. This "one-size-fits-all" fertilization model cannot meet the needs of precision agriculture, not only wasting water and fertilizer resources, but also reducing the actual effect of irrigation equipment, thus restricting the improvement of agricultural production efficiency and crop quality. Summary of the Invention

The small pulley is connected to the large pulley via belt drive. The rear end of the assist rod penetrates the front inner wall of the circular mixing chamber. The rotating main rod is fixedly installed on a part of the assist rod that extends into the circular mixing chamber. At one end, the connecting plate is fixedly installed on the outside of the rotating main rod, the arc-shaped scraper is fixedly installed on the end of the connecting plate away from the center, the limiting stirring rod is fixedly installed on the outside of the rotating main rod, and the connecting plate and the limiting stirring rod are staggered, the movable cylinder is movably sleeved on the outside of the limiting stirring rod, the stirring blade is fixedly installed on the outside of the movable cylinder, the inner wall of the circular mixing chamber and the bottom of the circular mixing chamber are provided with a transfer chamber, the arc-shaped filter plate is embedded at the connection between the transfer chamber and the circular mixing chamber, and the bottom of the arc-shaped scraper is in contact with the inner side of the arc-shaped filter plate.

[0007] As an improvement to the above technical solution, the spraying mechanism includes a liquid outlet pipe, a diversion pipe, a main spraying pipe, and a nozzle. The liquid outlet pipe is fixedly installed at the bottom of the mixing tank and is connected to the transfer chamber. A circular hole is provided on the top of the electric flat plate assembly, and the bottom of the liquid outlet pipe extends to the lower side of the electric flat plate assembly through the circular hole. The diversion pipe is fixedly installed at the bottom end of the liquid outlet pipe. The main spraying pipe is symmetrically fixed at both ends of the diversion pipe, and the nozzle is fixedly installed on the outside of the main spraying pipe.

[0008] As an improvement to the above technical solution, a protective cover is detachably installed on the front side of the electric flat panel assembly by bolts, and a top cover is symmetrically and movablely attached to the top of the electric flat panel assembly.

[0011] As an improvement to the above technical solution, there are two arc-shaped feeding troughs with different widths, and there are two horizontal baffles with different widths of the connecting openings on the two horizontal baffles.

[0012] As an improvement to the above technical solution, there are multiple nozzles, and the multiple nozzles are arranged linearly on the outside of the spray main pipe, and the nozzles on the front and rear spray main pipes are staggered.

[0013] A method for an agricultural rolling alternating irrigation and fertilization device includes the following steps: S10: Start-up: The equipment is started by PLC control, which causes the power motor to drive the power gear to rotate. The power gear meshes and drives the auxiliary gear plates on both sides to move. The auxiliary gear plates on both sides drive their corresponding horizontal baffles to move to the position to block the arc-shaped feeding chute.

S30: Mixing: Based on the growth of crops in the farmland, the mixing concentration of water and fertilizer is input at the terminal. Then, the motor drives the horizontal baffles on both sides to move and input an appropriate amount of water and fertilizer into the circular mixing chamber. The water and fertilizer are mixed by rotating the stirring blades and other structures. During the mixing process, the concentration of water and fertilizer is monitored in real time by the concentration detector and the data is transmitted to the terminal. The terminal adjusts the water flow and fertilizer feed rate at every moment based on the monitored real-time data. When the required water and fertilizer concentration of the next farmland needs to be changed, the feed rate of water and fertilizer can be changed by controlling the horizontal baffles and other structures on both sides. S40: Spraying: After the water and fertilizer are mixed to the specified concentration, the equipment is moved by the electric plate assembly, and the direction is controlled by personnel. Then, multiple nozzles at the bottom of the electric plate assembly perform cross-spraying operations.

[0014] The beneficial effects of this invention are as follows: Based on the growth conditions of crops in different farmlands, the water and fertilizer are mixed and stirred in a rolling manner by adjusting and stirring mechanisms, while the amount of water and fertilizer is alternately controlled in real time to achieve a suitable water and fertilizer concentration for the farmland. Then, cross-spraying is carried out by spraying mechanisms. This "precision" fertilization mode can meet the needs of refined agriculture, not only reducing the waste of water and fertilizer resources, but also improving the actual effect of irrigation equipment, and promoting the improvement of agricultural production efficiency and crop quality.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] Reference Appendix Figure 1 ,exist Figure 1 In the diagram, 'a' points to the front view and 'b' points to the right-side view. These views are only used to understand the scheme.

[0019] Example 1 Please refer to Figures 1-9 As shown, the present invention provides an agricultural rolling alternating irrigation water and fertilizer device, including an electric flat plate assembly 1, a mixing box 2 fixedly installed on the top of the electric flat plate assembly 1, a power chamber 21 opened on the front side of the electric flat plate assembly 1, a storage chamber 23 symmetrically opened on the top of the electric flat plate assembly 1, and a circular mixing chamber 24 opened inside the electric flat plate assembly 1 and below the storage chamber 23. The storage bin 23 and the circular mixing bin 24 are provided with an adjustment mechanism for controlling the discharge flow rate in an alternating displacement manner; Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the amount of water and fertilizer supplied can be controlled in real time according to the water and fertilizer concentration requirements of different crops in different farmlands by adjusting the internal structure of the mechanism.

[0020] The circular mixing chamber 24 has a rotating agitator arranged in a circular pattern inside for mixing water and fertilizer, and the adjusting mechanism is connected to the agitator for transmission. Please refer to Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 9 As shown, the mixing of fertilizer and water in the circular mixing chamber 24 is accelerated by the forward and reverse rotation of the internal structure of the stirring mechanism.

[0021] The lower side of the electric flat plate assembly 1 is symmetrically fixed with a spraying mechanism for irrigation and fertilizer spraying.

[0022] Please refer to Figure 2 and Figure 6 As shown, the uniformity of spraying is ensured by cross-spraying through the coordination of the internal structure of the spraying mechanism.

[0023] In the above scheme, all electrical components in this equipment are controlled by PLC and equipped with a mature communication system for reasonable auxiliary operation. According to the growth conditions of crops in different farmlands, the water and fertilizer are mixed and stirred in a rolling manner through the adjustment mechanism and the stirring mechanism, while the water source and fertilizer feed are alternately controlled in real time to obtain a suitable water and fertilizer concentration for the farmland. Then, the spraying mechanism performs cross-spraying operations. This "precision" fertilization mode can meet the needs of refined agriculture, not only reducing the waste of water and fertilizer resources, but also improving the actual effect of irrigation equipment, and promoting the improvement of agricultural production efficiency and crop quality.

[0024] Specifically, the adjustment mechanism includes a horizontal baffle 32, an assist gear plate 34, a motor bracket 35, a power motor 36, a large pulley 37, and a power gear 38. A horizontal slot 3 is provided inside the electric flat assembly 1, located between the storage bin 23 and the circular mixing bin 24. An arc-shaped discharge chute 31 is provided in the middle of the bottom of the storage bin 23, and the arc-shaped discharge chute 31 is connected to the circular mixing bin 24. The horizontal slot 3 and the arc-shaped discharge chute 31 intersect each other. The horizontal baffle 32 is slidably engaged within the horizontal slot 3. The top of 32 has sequentially arranged connecting openings 33 of different widths. The assisting tooth plate 34 is fixedly installed at the front end of the horizontal baffle 32 that extends into the power chamber 21. The motor bracket 35 is fixedly installed on the rear inner wall of the power chamber 21 and located on the upper side of the assisting tooth plate 34. The power motor 36 is fixedly installed on the inner side of the motor bracket 35. The large pulley 37 is fixedly installed at the output end of the power motor 36. The power gear 38 is fixedly installed at the rear end of the large pulley 37 and meshes with the assisting tooth plate 34.

[0025] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, in the above scheme, according to the water and fertilizer concentration required by the terminal input, the power motor 36 is started. The power motor 36 drives the large pulley 37 to rotate. The large pulley 37 drives the stirring mechanism to rotate via a belt. The large pulley 37 drives the power gear 38 to rotate. The power gear 38 drives the auxiliary tooth plates 34 on both sides to move through meshing. The auxiliary tooth plates 34 on both sides drive their corresponding horizontal baffles 32 to move. The horizontal baffles 32 on both sides drive the connecting port 33 to move, thereby controlling the size of the gap between the connecting port 33 and the arc-shaped feeding trough 31. Then, the water source in the left storage bin 23 and the fertilizer in the right storage bin 23 will flow into the circular feed trough through their respective arc-shaped feeding troughs 31. Inside the circular mixing chamber 24, a stirring mechanism simultaneously mixes water and fertilizer to form a slurry. A concentration detector 7 monitors the concentration of the slurry and fertilizer in the circular mixing chamber 24 in real time and transmits the data to a terminal. The terminal controls the power motor 36 to rotate in both directions based on the monitored real-time data. The power motor 36 drives the horizontal baffles 32 on both sides to move back and forth, thereby adjusting the amount of water and fertilizer fed at any given moment. When the required slurry and fertilizer concentration for a particular farmland needs to be changed, the amount of water and fertilizer fed can be adjusted by using the horizontal baffles 32 on both sides and other structures. By coordinating the internal structure of the adjustment mechanism, the amount of water and fertilizer fed can be controlled in real time according to the slurry and fertilizer concentration requirements of different crops in different farmlands.

[0026] Specifically, the agitation mechanism includes an assist rod 4, a small pulley 41, a rotating main rod 42, a connecting plate 43, an arc-shaped scraper 44, a limiting stirring rod 45, a movable cylinder 46, stirring blades 47, and an arc-shaped filter plate 49. The assist rod 4 is rotatably connected to the rear inner wall of the power chamber 21 and located below the assist toothed plate 34. The small pulley 41 is fixedly installed at the front end of the assist rod 4, and the small pulley 41 is connected to the large pulley 37 via belt drive. The rear end of the assist rod 4 penetrates the front inner wall of the circular mixing chamber 24. The rotating main rod 42 is fixedly installed at one end of the assist rod 4 that extends into the circular mixing chamber 24, and is connected to... Plate 43 is fixedly installed on the outside of rotating main rod 42, arc-shaped scraper plate 44 is fixedly installed on the end of connecting plate 43 away from the center, limiting stirring rod 45 is fixedly installed on the outside of rotating main rod 42, and connecting plate 43 and limiting stirring rod 45 are staggered, movable cylinder 46 is movably sleeved on the outside of limiting stirring rod 45, stirring blade 47 is fixedly installed on the outside of movable cylinder 46, and a transfer chamber 48 is opened on the inner wall of circular mixing chamber 24 and at the bottom, arc-shaped filter plate 49 is embedded at the connection between transfer chamber 48 and circular mixing chamber 24, and the bottom of arc-shaped scraper plate 44 is in contact with the inner side of arc-shaped filter plate 49.

[0027] Please refer to Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 9As shown in the above scheme, during the process of fertilizer and water entering the circular mixing chamber 24, the large pulley 37 rotates in both directions, driving the small pulley 41 to accelerate in both directions under the action of the belt. The small pulley 41 drives the assist rod 4 to rotate, which in turn drives the main rotating rod 42 to rotate. The main rotating rod 42 drives the limiting stirring rod 45 to rotate, which in turn drives the movable cylinder 46 to revolve. During the revolution, the movable cylinder 46 moves back and forth along the limiting stirring rod 45 under the action of gravity. The movable cylinder 46 drives the stirring blade 47 to rotate during the revolution. The mixing mechanism moves back and forth, while the stirring blade 47 rotates on its own axis to the left and right of the water flow. The stirring blade 47 mixes the water and fertilizer in multiple ways, thereby accelerating the mixing of fertilizer and water. At the same time, the rotating main rod 42 drives the connecting plate 43 to rotate, and the connecting plate 43 drives the arc-shaped scraper 44 to rotate. When the arc-shaped scraper 44 rotates, it scrapes the fertilizer that falls to the bottom of the arc-shaped filter plate 49 during the mixing process and pushes it upward for mixing. Through the cooperation of the internal structure of the stirring mechanism, forward and reverse rotation mixing is achieved, thereby accelerating the mixing of fertilizer and water in the circular mixing chamber 24.

[0028] Specifically, the spraying mechanism includes an outlet pipe 5, a diversion pipe 51, a main spraying pipe 52, and a nozzle 53. The outlet pipe 5 is fixedly installed at the bottom of the mixing tank 2 and is connected to the transfer chamber 48. A round hole is opened on the top of the electric flat plate assembly 1, and the bottom of the outlet pipe 5 extends to the lower side of the electric flat plate assembly 1 through the round hole. The diversion pipe 51 is fixedly installed at the bottom end of the outlet pipe 5. The main spraying pipe 52 is symmetrically fixed at both ends of the diversion pipe 51, and the nozzle 53 is fixedly installed on the outside of the main spraying pipe 52.

[0029] Please refer to Figure 2 and Figure 6 As shown in the above scheme, after the water and fertilizer in the circular mixing chamber 24 are mixed, the water and fertilizer pass through the arc-shaped filter plate 49 and fall into the transfer chamber 48, and are discharged through the liquid outlet pipe 5. Then, they are diverted through the diversion pipe 51 into the spray main pipes 52 on both sides, and then sprayed out through the nozzles 53. The uniformity of spraying is ensured by the cross-spraying nozzles 53 on both sides. The uniformity of spraying is also ensured by the cross-spraying through the cooperation of the internal structure of the spraying mechanism.

[0030] Specifically, a protective cover 22 is detachably installed on the front side of the electric flat panel assembly 1 by bolts, and a top cover 6 is symmetrically and movablely attached to the top of the electric flat panel assembly 1.

[0031] Please refer to Figure 1 As shown, in the above scheme, the internal structure of the power compartment 21 is protected by the protective cover 22, and the top covers 6 on both sides are used to prevent debris from falling into the storage compartments 23 on both sides.

[0032] Specifically, the inner wall of the circular mixing chamber 24 is embedded with a concentration detector 7. There are multiple concentration detectors 7, and the multiple concentration detectors 7 are arranged in a circular pattern.

[0033] Please refer to Figure 3 As shown in the figure, in the above scheme, multiple concentration detectors 7 are used to monitor the concentration of water and fertilizer in the circular mixing chamber 24 in real time, which facilitates the subsequent control of the amount of water and fertilizer entering.

[0034] Specifically, the top of the connecting opening 33 on the horizontal baffle 32, which is narrower than the arc-shaped feeding trough 31, is designed with rounded corners.

[0035] Please refer to Figure 8 As shown, in the above scheme, the materials falling into the arc-shaped feeding trough 31 can fall downward through the connecting port 33.

[0036] Specifically, there are two arc-shaped feeding troughs 31, and the widths of the two arc-shaped feeding troughs 31 are different. There are two horizontal baffles 32, and the widths of the connecting openings 33 on the two horizontal baffles 32 are also different.

[0037] Please refer to Figure 3 As shown in the above scheme, since the water demand in the water-fertilizer mixture is much greater than that of the fertilizer, the amount of water and fertilizer discharged per unit time is controlled by ensuring that the widths of the arc-shaped discharge troughs 31 and the connecting openings 33 on both sides are the same.

[0038] Specifically, there are multiple nozzles 53, and the multiple nozzles 53 are arranged linearly on the outside of the spray main pipe 52, and the nozzles 53 on the front and rear spray main pipes 52 are staggered.

[0039] Please refer to Figure 6 As shown, in the above scheme, the spraying range is expanded by using multiple cross-arranged nozzles 53 while ensuring the uniformity of spraying.

[0040] Example 2 To complement the scheme described in Embodiment 1, a method for an agricultural rolling alternating irrigation water and fertilizer device is also provided, employing the agricultural rolling alternating irrigation water and fertilizer device described in Embodiment 1, comprising the following steps: S10: Start-up: The equipment is started by controlling the PLC, which causes the power motor 36 to drive the power gear 38 to rotate. The power gear 38 drives the auxiliary gear plates 34 on both sides to move through meshing. The auxiliary gear plates 34 on both sides drive their corresponding horizontal baffles 32 to move to the position to block the arc-shaped feed chute 31. S20: Feeding: Open the two storage bins 23 on the upper side of the mixing box 2, connect the water pipe joint on the left side of the mixing box 2 to the external water pipe, inject water into the storage bin 23 on the left side through the external water pipe, and pour fertilizer into the storage bin 23 on the right side, and then cover the top cover 6 on each side. S30: Mixing: Based on the growth of crops in the farmland, the mixing concentration of water and fertilizer is input at the terminal. Then, the power motor 36 drives the horizontal baffles 32 on both sides to move and input an appropriate amount of water and fertilizer into the circular mixing chamber 24. The water and fertilizer are mixed and stirred by the rotation of the stirring blades 47 and other structures. During the stirring process, the concentration of water and fertilizer is monitored in real time by the concentration detector 7 and the data is transmitted to the terminal. The terminal adjusts the amount of water and fertilizer fed at every moment based on the monitored real-time data. When the required water and fertilizer concentration of the next farmland needs to be changed, the amount of water and fertilizer fed can be changed by the horizontal baffles 32 on both sides and other structures. S40: Spraying: After the water and fertilizer are mixed to the specified concentration, the equipment is moved by the electric plate assembly 1 and the direction is controlled by personnel. Then, multiple nozzles 53 at the bottom of the electric plate assembly 1 perform cross-spraying operations.

An agricultural rolling alternating irrigation and fertilization device according to claim 4, characterized in that: There are multiple nozzles (53), and the multiple nozzles (53) are arranged linearly on the outside of the spray main pipe (52), and the nozzles (53) on the front and rear spray main pipes (52) are interleaved.

10. A method for an agricultural rolling alternating irrigation water and fertilizer system, applied to an agricultural rolling alternating irrigation water and fertilizer system as described in any one of claims 1-9, characterized in that: Includes the following steps: S10: Start-up: The equipment is started by controlling the PLC, so that the power motor (36) drives the power gear (38) to rotate. The power gear (38) drives the auxiliary gear plates (34) on both sides to move through meshing. The auxiliary gear plates (34) on both sides drive their corresponding horizontal baffles (32) to move, so that the horizontal baffles (32) on both sides move to the position to block the arc-shaped feed chute (31). S20: Feeding: Open the two storage bins (23) on the upper side of the mixing box (2), connect the water pipe joint on the left side of the mixing box (2) to the external water pipe, inject water into the storage bin (23) on the left side through the external water pipe, and pour fertilizer into the storage bin (23) on the right side, and then cover the top cover (6) respectively. S30: Mixing: Based on the growth of crops in the farmland, the mixing concentration of water and fertilizer is input at the terminal. Then, the power motor (36) drives the horizontal baffles (32) on both sides to move and input an appropriate amount of water and fertilizer into the circular mixing chamber (24). The water and fertilizer are mixed and stirred by rotating the stirring blades (47). During the stirring process, the concentration of water and fertilizer is monitored in real time by the concentration detector (7), and the data is transmitted to the terminal. The terminal adjusts the amount of water flow and fertilizer at every moment according to the real-time data monitored. When the required water and fertilizer concentration of the next farmland needs to be changed, the amount of water and fertilizer can be changed by controlling the amount of water and fertilizer through the horizontal baffles (32) on both sides. S40: Spraying: When the water and fertilizer are mixed to the specified concentration, the equipment is moved by the electric plate assembly (1) and the direction is controlled by personnel. Then, multiple nozzles (53) at the bottom of the electric plate assembly (1) carry out cross-spraying operations.
