Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, and in particular to a crop irrigation device and its control system for agricultural planting. Background Technology

[0002] Agricultural irrigation mainly refers to irrigation operations carried out in agricultural cultivated areas. Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation, and micro-irrigation. In addition, ordinary sprinkler irrigation technology is the most common irrigation method in Chinese agricultural production, but the water use efficiency of ordinary sprinkler irrigation technology is not high. Modern agricultural micro-irrigation technology includes micro-sprinkler irrigation, drip irrigation, and seepage irrigation. These irrigation technologies generally have good water-saving performance and higher water use efficiency than traditional irrigation modes. Of course, they also have some drawbacks. Ancient Chinese agricultural irrigation relied on rainfall and rivers, and farming was mainly concentrated in areas with abundant rainfall and well-developed river networks. Farmers in these areas often carried out agricultural production according to the solar terms.

[0003] In light of the above, it should be noted that: Traditional agricultural irrigation requires the mixing of a fixed amount of fertilizer according to the needs of plant growth. Due to the influence of fertilizer type, solubility, and other factors, the mixed irrigation water is prone to blockage in some irrigation nozzles after being transported to the irrigation heads, or affects the irrigation spraying efficiency. Traditional mixing and conveying devices for agricultural irrigation water have a directional and simple internal mixing method. Under the demand for large-scale agricultural irrigation output, some non-mixed or poorly soluble fertilizers may precipitate or adhere to the inner wall of the mixing structure. This not only affects the formation efficiency of irrigation water and the uneven fertility within the irrigation water, but also causes the device to be shut down for cleaning and maintenance, thus affecting irrigation efficiency.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an irrigation device and control system for agricultural planting. By collecting water mixing information during the irrigation process in agriculture, relevant data on external water factors, fertilizer and water factors, and water delivery factors related to irrigation water are obtained. These data are then redefined, modified, analyzed, and compared to obtain associated process evaluation signals. Based on these signals, the control components are re-executed to compensate for deficiencies in the previous processing, thereby improving the water mixing effect of irrigation water and preventing uneven mixing of irrigation water from causing blockages in local irrigation nozzles, thus solving the aforementioned problems.

A pressure plate that is sleeved with the sliding rod is provided above the sliding frame. A servo motor is provided at the bottom center of the pressure plate, and rings are provided at both ends of the pressure plate.

[0008] Preferably, the lower convex plate is fixed to the top center of the base, and the top of both ends of the lower convex plate are provided with annular conical grooves.

A second annular suction port is provided below the second sinking suction port. A second sinking suction port is provided below the inner ring of the second annular suction port. An upper spray port is provided on the top inner wall of the inner arc plate.

[0009] Preferably, the top of both ends of the top cover is provided with an upper sleeve shaft that is sleeved with the slide rod, the surface of the slide rod is provided with a telescopic sleeve that connects the sliding frame and the pressure plate, the top outer wall of the top cover is provided with a water inlet and a fertilizer inlet, the bottom inner wall of the top cover is provided with multiple sets of internal spray nozzles, and the bottom side inner wall of the top cover is provided with multiple sets of return air ports.

[0010] Preferably, the sliding frame is provided with a central support frame fixedly connected to the drive motor in the middle, and the sliding frame is provided with sliding sleeves for connecting the sliding rods in the middle of both ends. The bottom outer wall of the sliding sleeve is connected to the stirring paddle. The bottom of the drive motor is provided with a worm gear for connecting the stirring paddle, and the top outer shell of the drive motor is provided with a vertical electromagnetic drag rod.

[0011] Preferably, the servo motor has multiple sets of bidirectional threaded rods facing the ring at its bottom. Large frames with multiple through-pressure plates are symmetrically arranged on both sides of the bidirectional threaded rods. A shaped plate is slidably installed inside the large frame. The shaped plate is threadedly connected to the bidirectional threaded rod. Multiple sets of rectangular slots are arranged in a ring array inside the ring. A rotating fan is sleeved in the center of the ring. The outer wall of the rotating fan is provided with transmission teeth that connect to the bidirectional threaded rod.

[0012] A control system for a crop irrigation device used in agricultural planting, wherein the control panel is internally equipped with a processor, a data acquisition module, a self-test feedback module, and a signal execution module;

[0013] The data acquisition module is used to collect water mixing condition information of irrigation water during the mixed irrigation process in agriculture and transmit it to the self-test feedback module. The water mixing condition information consists of external water factor, fertilizer-water factor and water delivery factor of irrigation water. The external water factor represents the total amount of clean water input into the mixing cylinder within and outside the time threshold. The fertilizer-water factor represents the total amount of water-based fertilizer input into the mixing cylinder within and outside the time threshold. The water delivery factor represents the total amount of mixed irrigation water output from the mixing cylinder to the irrigation nozzle within the time threshold.

[0014] The self-inspection feedback module then performs irrigation water mixing monitoring and analysis based on the received information on the water mixing conditions of irrigation water during the agricultural mixed irrigation process. The specific analysis process is as follows:

[0015] A: Obtain the water mixing condition information of irrigation water in the mixed output irrigation process in agriculture, and mark the external water factor, fertilizer water factor and water transport factor as Qi, Wi and Ei respectively, where i is a positive integer greater than zero;

[0016] B: According to the formula The process bonding magnitude R of the fabric during the bonding process is obtained, where q, w, and e are all process correction factors, e > q > w > 0, and e + q + w = ​​2.75;

[0017] C: When the water mixing level R of irrigation water in the mixed output irrigation process in agriculture is greater than the maximum value of the preset range r, is within the preset range, or is less than the minimum value of the preset range r, then it will generate a process excellent signal, a process general signal, and a process poor signal respectively.

[0018] Furthermore, the excellent, normal, and poor process signals corresponding to the irrigation water in the mixed irrigation process of agriculture are transmitted to the signal execution module via the processor. Upon receiving the normal process signal, the signal execution module immediately controls the drive motor to work. Upon receiving the poor process signal, the signal execution module immediately controls the servo motor to work. Upon receiving the excellent process signal, the signal execution module does not perform any processing.

[0019] The beneficial effects of this invention are:

[0020] (1) This invention obtains relevant data on external water factors, fertilizer and water factors and water transport factors related to irrigation water by collecting water mixing condition information of irrigation water in the mixed output irrigation process in agriculture, and obtains the associated process evaluation signal by redefining, modifying formula analysis and comparison, and controls the component to perform the action again to make up for the deficiencies in the previous processing process, thereby improving the water mixing effect of irrigation water and avoiding the phenomenon of blockage of local irrigation nozzles due to uneven mixing of irrigation water.

[0021] (2) The present invention is to mechanically mix the external water and fertilizer water at the beginning of the irrigation water mixing. It uses a sliding frame to interact up and down or rotate and stir in a fixed area in the mixing cylinder, which promotes the full mixing of the external water and fertilizer water injected into the mixing cylinder from the local to the whole. At the same time, the lower convex plate assists the mixing cylinder to suck and pull, collect the sediment and aerate the irrigation water in the mixing cylinder, which helps the irrigation water in the mixing cylinder to mix quickly and evenly.

[0022] (3) The present invention uses the linkage and mutual cooperation of the pressure plate auxiliary mixing cylinder and the sliding frame structure. The pressure plate is temporarily closed and opened by using the irregular plate, rotating fan and large frame and ring sliding fit on the pressure plate. The pressure plate slides up and down in the mixing cylinder along the sliding rod with the sliding frame. In the closed state, the external water and fertilizer water to be mixed in the mixing cylinder are pushed to implement pressure mixing from top to bottom or lifting and flowing mixing from bottom to top. In the open state, the external water and fertilizer water to be mixed in the mixing cylinder are pushed to perform local squeezing and gushing mixing. In both states, the aeration and mechanical stirring are combined to form efficient mixing and full mixing of irrigation water. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] This embodiment addresses the problem that during traditional agricultural irrigation, a fixed amount of fertilizer needs to be mixed according to the growth requirements of the plants. However, due to the influence of fertilizer type, solubility, and other factors, the mixed irrigation water is prone to blockage in some irrigation nozzles after being transported through pipelines, or its irrigation spraying efficiency is affected.

[0034] Please see Figure 1 - Figure 6 As shown, this embodiment is a control system for a crop irrigation device used in agricultural planting, including a control panel 6. The control panel 6 is internally equipped with a processor, a data acquisition module, a self-test feedback module, and a signal execution module.

[0035] The data acquisition module is used to collect water mixing condition information of irrigation water during the mixed output irrigation process in agriculture and transmit it to the self-test feedback module. The water mixing condition information consists of external water factor, fertilizer-water factor and water delivery factor of irrigation water. The external water factor represents the total amount of clean water input into the mixing cylinder 2 within and outside the time threshold. The total amount of clean water is collected by the flow sensor 1 installed inside the water inlet. The fertilizer-water factor represents the total amount of water-based fertilizer input into the mixing cylinder 2 within and outside the time threshold. The total amount of water-based fertilizer is collected by the flow sensor 2 located inside the fertilizer inlet. The water delivery factor represents the total amount of mixed irrigation water output from the mixing cylinder 2 to the irrigation nozzle within the time threshold. The total amount of mixed irrigation water is collected by the flow sensor 3 inside the irrigation output valve. The time threshold represents the 20-minute operation period during the mixed output process in agriculture.

[0036] The self-inspection feedback module then performs irrigation water mixing monitoring and analysis based on the received information on the water mixing conditions of irrigation water during the agricultural mixed irrigation process. The specific analysis process is as follows:

[0037] A: Obtain the water mixing condition information of irrigation water in the mixed output irrigation process in agriculture, and mark the external water factor, fertilizer water factor and water transport factor as Qi, Wi and Ei respectively, where i is a positive integer greater than zero;

[0038] B: According to the formula The process bonding magnitude R of the fabric during the bonding process is obtained, where q, w, and e are all process correction factors, e > q > w > 0, and e + q + w = ​​2.75;

[0039] C: When the water mixing level R of irrigation water in the mixed output irrigation process in agriculture is greater than the maximum value of the preset range r, is within the preset range, or is less than the minimum value of the preset range r, then it will generate a process excellent signal, a process general signal, and a process poor signal respectively.

[0040] Furthermore, the excellent process signal, normal process signal, and poor process signal corresponding to the irrigation water in the mixed output irrigation process of agriculture are transmitted to the signal execution module through the processor;

[0041] After receiving the general process signal, the signal execution module immediately controls the drive motor 702 to work. The drive motor 702 drives the stirring paddle 704 to rotate via the coupling, worm gear and other transmission components. The stirring paddle 704 mechanically stirs the injected external water and water-based fertilizer. The lifting cylinder drives the sliding sleeve 703 to slide up and down along the sliding rod 302 via the transmission components. During the movement of the sliding sleeve 703, it drags the telescopic sleeve 303 to stretch. During the up and down movement of the sliding frame 7 within the mixing cylinder 2, the stirring paddle 704 mixes the external water and water-based fertilizer at different heights within the mixing cylinder 2.

[0042] Upon receiving a process degradation signal, the signal execution module immediately controls the servo motor 803 to operate. The vertical electromagnetic drag rod 705 is energized to generate magnetic force, which magnetically connects to the bottom of the pressure plate 8. As the sliding frame 7 slides down the slide rod 302, it drags the pressure plate 8 down synchronously. The servo motor 803 is connected to the bidirectional threaded rod 804 via a coupling and other transmission components. The bidirectional threaded rod 804 rotates, and the transmission components of the shaped plate 802 are threadedly engaged with the bidirectional threaded rod 804. The shaped plate 802 moves within the large opening frame 801 as the bidirectional threaded rod 804 rotates, thus closing and opening the large opening frame 801. Simultaneously, the bidirectional threaded rod 804 drives the rotating fan 806 to deflect within the ring 805 via a bevel gear or other transmission components. The fan blades of the rotating fan 806 deflect... The rectangular groove of the ring 805 is used to achieve the opening and closing of the rectangular groove. When the large opening frame 801 and the rectangular groove open synchronously, the pressure plate 8 slides up and down with the sliding frame 7. The irrigation water in the mixing cylinder 2 is pushed by the pressure plate 8 and the sliding frame 7 and flows through the large opening frame 801 and the rectangular groove. When the large opening frame 801 and the rectangular groove close synchronously, the pressure plate 8 pushes the irrigation water from top to bottom with the sliding frame 7. The regulating valve opens and the pushed irrigation water flows into the upper spray nozzle 203 through the first settling suction port 207, the second settling suction port 209, the pipe and the regulating valve. It is then sprayed from the top to the top of the pressure plate 8. After the pressure plate 8 moves to the bottom of the mixing cylinder 2 in the closed state, the large opening frame 801 and the rectangular groove open, and the irrigation water in the mixing cylinder 2 is repeatedly stirred in a flowing manner.

[0043] The signal execution module does not perform any processing after receiving the process excellent signal.

[0044] Example 2:

[0045] This embodiment addresses the problem that traditional mixing and conveying devices for agricultural irrigation water have a directional and simple internal mixing method. Under the demand for large-scale agricultural irrigation output, this can lead to the sedimentation or adhesion of partially mixed, non-mixed, and poorly soluble fertilizers on the inner wall of the mixing structure. This not only affects the efficiency of irrigation water formation and the uneven fertility within the irrigation water, but also causes the device to be shut down for cleaning and maintenance, thus affecting irrigation efficiency.

[0046] Please see Figure 1 - Figure 5As shown, the crop irrigation device and its control system for agricultural planting in this embodiment include a base 1, a mixing cylinder 2 on the top of the base 1, an air pump box 4 at the bottom of the outer wall of one end of the base 1, a drive box 5 on the side of the air pump box 4, a water pump inside the drive box 5, and a control panel 6 fixedly installed on the top of the drive box 5. Inner arc plates 201 are provided on the inner walls of both ends of the mixing cylinder 2, a lower convex plate 202 is provided at the bottom of the inner arc plate 201, and a lower sleeve shaft 204 is provided at the center of the top of the lower convex plate 202. Multiple irrigation output valves are provided on the bottom outer wall of one end of the mixing cylinder 2. A top cover 3 is snapped onto the top of the mixing cylinder 2. A slide rod 302 is provided at the bottom of the top cover 3 and is sleeved with the lower sleeve shaft 204. A sliding frame 7 is slidably sleeved in the middle of the slide rod 302. A drive motor 702 is provided in the middle of the sliding frame 7. A stirring paddle 704 is symmetrically provided at both ends of the sliding frame 7. A pressure plate 8 is provided above the sliding frame 7 and is sleeved with the slide rod 302. A servo motor 803 is provided at the bottom center of the pressure plate 8. A ring 805 is provided at both ends of the pressure plate 8.

[0047] External clean water and water-based fertilizer are transported through water inlet and fertilizer inlet pipes respectively, and dispersed into the mixing cylinder 2 through the inner nozzle. An air pump is installed in the air pump box 4, which is connected to the air return port through a pipeline and extracts air from the mixing cylinder 2 to maintain the air pressure in the mixing cylinder 2. The drive motor 702 drives the stirring paddle 704 to rotate through the coupling, worm gear and other transmission components. The stirring paddle 704 mechanically stirs the injected external water and water-based fertilizer. The lifting cylinder drives the sliding sleeve 703 to slide up and down along the sliding rod 302 through the transmission components. During the movement of the sliding sleeve 703, it drags the telescopic sleeve 303 to stretch. During the up and down movement of the sliding frame 7 by the sliding sleeve 703 in the mixing cylinder 2, the stirring paddle 704 mixes the external water and water-based fertilizer at different heights in the mixing cylinder 2.

[0048] The lower convex plate 202 is fixed to the top center of the base 1. Annular conical grooves are provided at the top of both ends of the lower convex plate 202, and multiple sets of first aeration ports 205 are provided at the top center of the lower convex plate 202. A first annular suction port 206 is provided on the inner wall of the top of the annular conical groove. A first sinking suction port 207 is provided below the first annular suction port 206. A second sinking suction port 210 is provided below the first sinking suction port 207. A second annular suction port 208 is provided below the second sinking suction port 210. A second sinking suction port 209 is provided below the inner ring of the second annular suction port 208. The inner arc plate... An upper nozzle 203 is provided on the inner wall of the top of 201. Inside the upper nozzle 203, a regulating valve and pipe are provided for connecting the first settling suction port 207 and the second settling suction port 209. The air pump is connected to the first aeration port 205 and the second aeration port 210 through the pipeline and injects air bubbles into the mixing cylinder 2 from bottom to top. The air bubbles float up and are released from the stirring paddle 704. Under the multiple action of irrigation water and stirring paddle 704, the air bubbles break and split, and at the same time promote the irrigation water to be further mixed. The return air port guides the air collected at the top of the mixing cylinder 2 to circulate into the first aeration port 205 and the second aeration port 210.

[0049] The top of both ends of the top cover 3 are provided with upper sleeve shafts 301 that are sleeved with slide rods 302. The surface of the slide rod 302 is provided with telescopic sleeves 303 that connect the sliding frame 7 and the pressure plate 8. The top outer wall of the top cover 3 is provided with water inlet and fertilizer inlet, and the bottom inner wall of the top cover 3 is provided with multiple sets of internal spray nozzles. The bottom side inner wall of the top cover 3 is provided with multiple sets of air return ports. A limiting groove is opened through the outer wall of the slide rod 302, and a lifting cylinder is embedded in the limiting groove. Water and water-based fertilizer are mixed inside and outside the mixing cylinder 2 for a certain period of time. Then, the water pump is connected to the first annular suction port 206 and the second annular suction port 208 via pipeline. It draws the mixed irrigation water from the bottom of the mixing cylinder 2. Meanwhile, the first aeration port 205, the second aeration port 210, the first annular suction port 206, and the second annular suction port 208 at both ends of the mixing cylinder 2 are started intermittently at the same end. This forms an alternating aeration, tumbling and stirring and negative pressure drainage at both ends of the mixing cylinder 2, which effectively avoids the sedimentation of undissolved fertilizer in some areas at the bottom of the mixing cylinder 2.

[0050] The sliding frame 7 has a central support 701 fixedly connected to the drive motor 702 in the middle. The sliding frame 7 has a sliding sleeve 703 at the middle of both ends for connecting with the sliding rod 302. The bottom outer wall of the sliding sleeve 703 is connected to the stirring paddle 704. The bottom of the drive motor 702 is provided with a worm gear for connecting to the stirring paddle 704. The top housing of the drive motor 702 is provided with a vertical electromagnetic drag rod 705.

[0051] The bottom of the servo motor 803 is provided with multiple sets of bidirectional threaded rods 804 facing the ring 805. On both sides of the bidirectional threaded rods 804, there are multiple large opening frames 801 that penetrate the pressure plate 8. A special-shaped plate 802 is slidably installed inside the large opening frame 801. The special-shaped plate 802 is threadedly connected to the bidirectional threaded rods 804. Multiple sets of rectangular slots are arranged in a ring array inside the ring 805. A rotating fan 806 is sleeved in the center of the ring 805. The outer wall of the rotating fan 806 is provided with transmission teeth that connect with the bidirectional threaded rods 804. The top corner of the pressure plate 8 is provided with claw buckles that engage with the top cover 3.

[0052] The vertical electromagnetic towing rod 705 generates magnetic force when energized, and it magnetically connects to the bottom of the pressure plate 8. As the sliding frame 7 slides down along the sliding rod 302, it drags the pressure plate 8 down synchronously. The servo motor 803 is connected to the bidirectional threaded rod 804 via a coupling and other transmission components. When the bidirectional threaded rod 804 rotates, the transmission component of the irregular plate 802 is threadedly engaged with the bidirectional threaded rod 804. The irregular plate 802 moves within the large opening frame 801 as the bidirectional threaded rod 804 rotates, thus closing and opening the large opening frame 801. Simultaneously, the bidirectional threaded rod 804 drives the rotating fan 806 to deflect within the ring 805 via a bevel gear or other transmission components. The fan blades of the rotating fan 806 deflect through the rectangular groove of the ring 805, realizing the opening of the rectangular groove. When the large opening frame 801 and the rectangular groove open simultaneously, the pressure plate 8 slides up and down with the sliding frame 7. The irrigation water in the mixing cylinder 2 is pushed by the pressure plate 8 and the sliding frame 7 and flows through the large opening frame 801 and the rectangular groove. When the large opening frame 801 and the rectangular groove close simultaneously, the pressure plate 8 pushes the irrigation water from top to bottom with the sliding frame 7. The regulating valve opens, and the pushed irrigation water flows into the upper spray nozzle 203 through the first settling suction port 207, the second settling suction port 209, the pipe and the regulating valve, and is sprayed from the top to the top of the pressure plate 8. After the pressure plate 8 moves to the bottom of the mixing cylinder 2 in the closed state, the large opening frame 801 and the rectangular groove open, and the irrigation water in the mixing cylinder 2 is repeatedly stirred in a flowing manner.

[0053] Combining Embodiments 1 and 2, it is possible to obtain relevant data on external water factors, fertilizer factors, and water conveyance factors related to irrigation water by collecting water mixing information during the irrigation process in agriculture. After redefining and modifying the formulas, analysis and comparison are performed to obtain related process evaluation signals. Based on this, the control components are executed again to make up for the deficiencies in the previous processing, thereby improving the water mixing effect of irrigation water and avoiding local clogging of irrigation nozzles due to uneven mixing of irrigation water. Furthermore, by performing multi-structure mechanical mixing of external water and fertilizer water at the beginning of irrigation water mixing, the sliding frame 7 is used to rotate and stir vertically or in a fixed area in the mixing cylinder 2, promoting the full mixing of external water and fertilizer water injected from the local area into the mixing cylinder 2. At the same time, the lower convex plate 202 is used to assist the mixing cylinder 2 in suction, traction, sedimentation and aeration of the mixed irrigation water, which helps to quickly and evenly mix the irrigation water in the mixing cylinder 2.

6. A control system for an agricultural irrigation device, used in any one of claims 1-5, characterized in that, The control panel (6) is internally equipped with a processor, a data acquisition module, a self-test feedback module and a signal execution module; The data acquisition module is used to collect the water mixing condition information of irrigation water in the mixed output irrigation process in agriculture and transmit it to the self-test feedback module. The water mixing condition information consists of the external water factor, fertilizer-water factor and water delivery factor of irrigation water. The external water factor represents the total amount of clean water input into the mixing cylinder (2) within and outside the time threshold. The fertilizer-water factor represents the total amount of water-based fertilizer input into the mixing cylinder (2) within and outside the time threshold. The water delivery factor represents the total amount of mixed irrigation water output from the mixing cylinder (2) to the irrigation nozzle within the time threshold. The self-inspection feedback module then performs irrigation water mixing monitoring and analysis based on the received information on the water mixing conditions of irrigation water during the agricultural mixed irrigation process. The specific analysis process is as follows: A: Obtain the water mixing condition information of irrigation water in the mixed output irrigation process in agriculture, and mark the external water factor, fertilizer water factor and water transport factor as Qi, Wi and Ei respectively, where i is a positive integer greater than zero; B: According to the formula The process bonding magnitude R of the fabric during the bonding process is obtained, where q, w, and e are all process correction factors, e > q > w > 0, and e + q + w = ​​2.75; C: When the water mixing level R of irrigation water in the mixed output irrigation process in agriculture is greater than the maximum value of the preset range r, is within the preset range, or is less than the minimum value of the preset range r, then it will generate a process excellent signal, a process general signal, and a process poor signal respectively. Furthermore, the excellent process signal, normal process signal, and poor process signal corresponding to the irrigation water in the mixed output irrigation process of agriculture are transmitted to the signal execution module via the processor. After receiving the normal process signal, the signal execution module immediately controls the drive motor (702) to work. After receiving the poor process signal, the signal execution module immediately controls the servo motor (803) to work. After receiving the excellent process signal, the signal execution module does not perform any processing.
