Description
Technical Field
[0001] This invention relates to the field of irrigation and fertilization equipment, and more specifically, to an integrated water-saving irrigation and fertilization equipment for wheat. Background Technology
[0002] The process of fertilizer entering the field along with irrigation water is called irrigation fertilization. Drip irrigation, underground drip irrigation, and other methods accurately supplement and evenly apply fertilizer near the root system according to the nutrient needs of crops at each stage of growth and climatic conditions, so that it can be directly absorbed and utilized by the roots. In the process of wheat irrigation fertilization, in order to save water, water-saving irrigation and fertilization integrated equipment is used to irrigate and fertilize wheat.
[0003] When using some existing water-saving irrigation and fertilization integrated equipment, because there are large particles in the granular fertilizer, after the smaller particles dissolve, it is necessary to wait for the larger particles to dissolve, which takes a long time and affects the efficiency of irrigation and fertilization.
[0004] To address the aforementioned technical issues, Chinese Patent No. CN216163402U discloses an integrated fertilizer and irrigation device for agriculture. This device uses a crushing rod to break down fertilizer particles, reducing their size and allowing for more complete dissolution in water. This improves the effectiveness of irrigation and fertilization for crops. A sieve plate then filters out the smaller fertilizer particles, which fall into the water, preventing larger particles from falling in and ensuring complete fertilizer dissolution.
[0005] Although the device solves the existing technical problems, when screening granular fertilizer, smaller fertilizer particles can fall through the screen plate into the water to dissolve, while larger fertilizer particles remain on the upper surface of the screen plate and are difficult to fall into the water to dissolve. After the smaller fertilizer particles are used up, the larger fertilizer particles need to be removed from the screen plate for reuse, which is time-consuming and labor-intensive and brings inconvenience to irrigation and fertilization work.
[0006] Therefore, a water-saving irrigation and fertilization integrated device for wheat is proposed. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] (1) This application sets up a screening mechanism, which realizes the function of screening granular fertilizer through the cooperation of screening screen, baffle, threaded rod and handwheel. It can separate larger granular fertilizer from smaller granular fertilizer, effectively avoiding the situation where smaller and larger granular fertilizers are mixed together and the larger granular fertilizers need to be dissolved after the smaller granules are dissolved.

[0022] (2) This application sets up a detection mechanism and uses a ruler to detect the movement position of the baffle, thereby realizing the function of detecting the movement position of the baffle, effectively avoiding the movement deviation of the baffle, improving the accuracy of the baffle movement, and ensuring the screening effect of the larger particle fertilizer for screening again.
[0023] (3) This application sets a limiting mechanism, pulls the slider to separate the locking rod from the through hole, and then takes out the scale. After the new scale is put into the limiting slide groove, the slider is released to make the locking rod insert into the through hole and fix the scale. This realizes the function of quick disassembly and assembly of the scale, which is convenient for replacing the scale.
[0024] (4) This application sets up a filtration mechanism, and the output end of the second motor rotates forward, causing the rotating plate and filter screen to rotate 180°. The impurities in the water accumulated between the rotating plate and the filter screen rotate to the top of the impurity outlet for discharge, realizing the function of quick filter screen switching. When the impurities accumulate and affect the water flow, the filter screen is quickly switched, and the impurities in the water are filtered and the accumulated impurities are discharged simultaneously. There is no need to stop the irrigation and fertilization work in the middle, which shortens the overall irrigation and fertilization time and improves the irrigation and fertilization efficiency of wheat.
[0025] (5) This application achieves the function of dust protection for the filter screen by setting up a protective mechanism and sealing the outlet through a sealing plate. The sealing plate can seal or unseal the outlet, effectively preventing particulate dust from adhering to the surface of the filter screen and affecting its use.
[0026] (6) This application sets up a fixing mechanism, pulls the connecting rod to separate the card block from the sealing plate, and then removes the sealing plate. After the new sealing plate is inserted into the guide rod, the sealing plate is fixed in position by the cooperation of the second spring and the card block, realizing the function of quick disassembly and assembly of the sealing plate, which facilitates the replacement of the sealing plate.

[0040] Includes a base plate 1, a mixing tank 2 is fixedly connected to the upper surface of the base plate 1, a liquid outlet pipe 3 is fixedly connected to the lower surface of the mixing tank 2, a water supply pipe 4 is fixedly connected to the upper surface of the mixing tank 2, a support frame 5 is fixedly connected to the upper surface of the base plate 1 located on one side of the mixing tank 2, and a water inlet pipe 6 is provided above the support frame 5.
[0041] The bottom plate 1 is fixedly connected to the upper surface of the mixing tank 2 on the other side by a screening mechanism 7 for screening granular fertilizer. The middle upper surface of the bottom plate 1 is fixedly connected to an extraction mechanism 8 for extracting granular fertilizer. The extraction mechanism 8 is fixedly connected to the mixing tank 2. The inner surface of the support frame 5 is fixedly connected to a filtration mechanism 9 for water filtration. The filtration mechanism 9 is fixedly connected to the water supply pipe 4 and the water inlet pipe 6 respectively.
[0042] The liquid outlet pipe 3 is connected to an external solution delivery pipeline and a water pump for fertilizer liquid delivery. The water delivery pipe 4 is connected to an external water flow delivery pipeline and a water pump for water flow delivery. The granular fertilizer and water flow are mixed through the mixing tank 2. The filter mechanism 9 is supported by the support frame 5.
[0043] like Figure 1 , Figure 2 and Figure 3As shown, the screening mechanism 7 includes a housing 71, a feed inlet 72, a cover plate 73, a first motor 74, a rotating shaft 75, a cam 76, a screening screen 77, a baffle 78, a threaded rod 79, a handwheel 710, and a detection mechanism 711. The housing 71 is fixedly connected to the upper surface of the bottom plate 1 on the other side of the mixing tank 2. The feed inlet 72 is opened on the upper surface of the housing 71. The cover plate 73 is rotatably connected to the upper surface of the housing 71 and is located above the feed inlet 72. The first motor 74 is fixedly connected to one side surface of the housing 71, and the output end of the first motor 74 is fixed. A rotating shaft 75 is connected to a housing 71. A cam 76 is fixedly connected to the outer surface of the rotating shaft 75. A screening screen 77 is slidably connected to the inner wall of the housing 71. The screening screen 77 is connected to the cam 76. A baffle 78 is slidably connected to the inner surface of the housing 71. A threaded rod 79 is threadedly connected to the inner surface of the baffle 78. The threaded rod 79 is rotatably connected to the housing 71. A handwheel 710 is fixedly connected to one end of the threaded rod 79. A detection mechanism 711 is fixedly connected to the side surface of the housing 71 near the handwheel 710.
[0044] In response to the problem that some existing water-saving irrigation and fertilization integrated equipment contains large granular fertilizer particles, and after the smaller particles dissolve, the larger particles still need to dissolve, which takes a long time and affects the efficiency of irrigation and fertilization, existing patents provide solutions. However, when screening granular fertilizer, the smaller fertilizer particles can fall into the water and dissolve, while the larger fertilizer particles remain on the upper surface of the screen and are difficult to fall into the water and dissolve. After the smaller fertilizer particles are used up, the larger fertilizer particles need to be removed from the screen and reused, which is time-consuming and labor-intensive and causes inconvenience to irrigation and fertilization work.
[0045] This invention includes a screening mechanism 7. When the first motor 74 is started, its output rotates, driving the rotating shaft 75 to rotate. The rotating shaft 75 then drives the cam 76 to rotate, which in turn moves the screening screen 77 up and down, creating a vibration effect. Next, the cover plate 73 is opened, and granular fertilizer is added into the housing 71. The granular fertilizer is screened by the vibrating screening screen 77. Smaller granules fall through the screen 77 to the lower part of the housing 71, while larger granules remain on the screen 77. On the upper surface of 7, after the granular fertilizer is added into the box 71, close the cover 73. After the smaller granular fertilizer in the lower part of the box 71 has been used up, turn the handwheel 710. The rotation of the handwheel 710 drives the threaded rod 79 to rotate. Then, the rotation of the threaded rod 79 drives the baffle 78 to move away from the screening screen plate 77 to a suitable position. The larger granular fertilizer on the screening screen plate 77 falls into the lower part of the box 71 through the space between the screening screen plate 77 and the baffle 78 for the use of larger granular fertilizer.
[0046] It realizes the function of granular fertilizer screening, which can separate larger and smaller granular fertilizers for use. It effectively avoids the situation where smaller and larger granular fertilizers are mixed together, and after the smaller granules dissolve, the larger granules still need to dissolve. This improves the efficiency of wheat irrigation and fertilization, and there is no need to remove the larger granular fertilizers from the screening screen 77 for use, which saves time and effort and facilitates wheat irrigation and fertilization.
[0047] like Figure 2 , Figure 4 and Figure 5 As shown, the detection mechanism 711 includes a mounting plate 7111, a limiting groove 7112, a scale 7113, a through hole 7114, and a limiting mechanism 7115. The mounting plate 7111 is fixedly connected to the side surface of the housing 71 near the handwheel 710. Two limiting grooves 7112 are symmetrically opened on the outer surface of the mounting plate 7111. A scale 7113 is slidably inserted into the surface of the two limiting grooves 7112. A through hole 7114 is opened on the outer surface of the scale 7113. The limiting mechanism 7115 is slidably connected to one side surface of the mounting plate 7111.
[0048] When larger fertilizer particles need to be screened again, the inside of the housing 71 is difficult to observe, which can easily lead to deviation of the baffle 78 and affect the screening effect. This invention provides a detection mechanism 711. When larger fertilizer particles need to be screened, the handwheel 710 is turned, which drives the threaded rod 79 to rotate. Then, the rotation of the threaded rod 79 drives the baffle 78 to move. During this process, the movement position of the baffle 78 is detected by the scale 7113 to ensure that the baffle 78 moves to the appropriate position.
[0049] The function of detecting the movement position of baffle 78 has been realized, which effectively avoids the movement deviation of baffle 78, improves the accuracy of the movement of baffle 78, and ensures the screening effect of larger fertilizer particles for secondary screening.
[0050] like Figure 2 and Figure 4As shown, the limiting mechanism 7115 includes a slider 71151, a locking rod 71152, a first spring 71153, and a first sliding rod 71154. The slider 71151 is slidably connected to one side surface of the mounting plate 7111, and the locking rod 71152 is fixedly connected to one side surface of the slider 71151. The locking rod 71152 is slidably inserted into the through hole 7114. The first spring 71153 is fixedly connected to the other side surface of the slider 71151. The first spring 71153 is fixedly connected to the mounting plate 7111. The first sliding rod 71154 is fixedly connected to the side surface of the locking rod 71152 near the first spring 71153. The first spring 71153 is sleeved on the outer surface of the first sliding rod 71154, and the first sliding rod 71154 is slidably connected to the mounting plate 7111.
[0051] To address the issue of wear and discoloration of the scale lines during long-term use of the ruler 7113, this invention includes a limiting mechanism 7115. When replacing the ruler 7113, the slider 71151 is pulled, causing the locking rod 71152 to separate from the through hole 7114. The ruler 7113 is then removed by pinching the through hole 7114. The new ruler 7113 is then placed into the limiting groove 7112. The slider 71151 is released, and the locking rod 71152 is engaged with the through hole 7114 by the elastic force of the first spring 71153, thus fixing the new ruler 7113. During this process, the stability of the first spring 71153 is ensured by the first sliding rod 71154.
[0052] It enables quick assembly and disassembly of the 7113 scale, making it easy to replace the 7113 scale.
[0053] like Figure 2 As shown, the screening screen 77 is inclined at a certain angle to the box body 71. The inclined setting of the screening screen 77 makes it easier for larger fertilizer particles to fall to the lower part of the box body 71.
[0054] like Figure 1 and Figure 2 As shown, the extraction mechanism 8 includes a pump 81, a first feed pipe 82, and a second feed pipe 83. The pump 81 is fixedly connected to the upper surface of the middle part of the base plate 1. The input end of the pump 81 is fixedly connected to the first feed pipe 82, which is fixedly connected to the housing 71. The output end of the pump 81 is fixedly connected to the second feed pipe 83, which is fixedly connected to the mixing tank 2.
[0055] When in use, start the material pump 81, and the granular fertilizer at the bottom of the box 71 enters the mixing tank 2 through the first feed pipe 82 and the second feed pipe 83 for mixing and dissolving;
[0056] It enables the quantitative feeding of granular fertilizer, is easy to operate, and facilitates irrigation and fertilization of wheat.
[0057] like Figure 1 , Figure 6 and Figure 7 As shown, the filtration mechanism 9 includes a housing 91, a second motor 92, a gear shaft 93, a first gear 94, a first one-way gear 95, a rotating plate 96, a filter screen 97, a waste outlet 98, and a protective mechanism 99. The housing 91 is fixedly connected to the inner surface of the support frame 5. The housing 91 is fixedly connected to the water supply pipe 4 and the water inlet pipe 6, respectively. The second motor 92 is fixedly connected to the upper surface of the housing 91. The output end of the second motor 92 is fixedly connected to the gear shaft 93. The first gear 94 is fixedly connected to the outer surface of the gear shaft 93. The first one-way gear 95 is meshed with the outer surface of the first gear 94. The rotating plate 96 is fixedly connected to the end face of the first one-way gear 95. The rotating plate 96 and the gear shaft 93 are rotatably connected to the housing 91. Two filter screens 97 are symmetrically fixedly connected to the outer surface of the rotating plate 96. The waste outlet 98 is opened on the lower surface of the housing 91. The protective mechanism 99 is meshed with the outer surface of the first gear 94.
[0058] In response to the problem that some existing water-saving irrigation and fertilization integrated equipment filters impurities in the water through a mesh filter, when the impurities accumulate and affect irrigation and fertilization, the filter screen 97 needs to be removed for cleaning or backwashing. During this process, the irrigation and fertilization work needs to be paused, resulting in a longer overall irrigation and fertilization time and thus affecting the efficiency of wheat irrigation and fertilization, this invention sets up a filtration mechanism 9.
[0059] Water is injected into the housing 91 through the water supply pipe 4, and then filtered through the filter screen 97 below the water supply pipe 4. The filtered water enters the mixing tank 2 through the water inlet pipe 6. Impurities in the water remain between the filter screen 97 and the rotating plate 96. When the accumulation of impurities affects the water flow, the second motor 92 is started. The output end of the second motor 92 rotates forward, driving the gear shaft 93 to rotate forward. Then, the gear shaft 93 rotates forward, driving the first gear 94 to rotate forward, which in turn drives the first one-way gear 95 to rotate. Then, the rotation of the first one-way gear 95 drives the rotating plate 96 to rotate, which in turn drives the filter screen 97 to rotate 180°. The impurities between the filter screen 97 and the rotating plate 96 rotate to the top of the impurity outlet 98 and are then discharged through the impurity outlet 98. At the same time, the water supplied by the water supply pipe 4 is filtered through another filter screen 97.
[0060] It achieves the function of quick switching of filter screen 97. When the accumulation of impurities affects the water flow, the filter screen 97 can be quickly switched to simultaneously filter impurities in the water and discharge accumulated impurities. There is no need to stop the irrigation and fertilization work in the middle, which shortens the overall irrigation and fertilization time and improves the irrigation and fertilization efficiency of wheat.
[0061] like Figure 6 and Figure 8 As shown, the protective mechanism 99 includes a second one-way gear 991, a rotating rod 992, a second gear 993, a toothed plate 994, a guide rod 995, a sealing plate 996, and a fixing mechanism 997. The outer surface of the first gear 94 is meshed with the second one-way gear 991. The end face of the second one-way gear 991 is fixedly connected to the rotating rod 992. One end of the rotating rod 992 is fixedly connected to the second gear 993. The outer surface of the second gear 993 is meshed with the toothed plate 994. The toothed plate 994 and the rotating rod 992 are rotatably connected to the housing 91. Two guide rods 995 are symmetrically fixedly connected to the lower surface of the toothed plate 994. The outer surfaces of the two guide rods 995 are slidably inserted with the sealing plate 996. The sealing plate 996 is connected to the toothed plate 994. The fixing mechanism 997 is fixedly connected to one side surface of the toothed plate 994.
[0062] To address the problem that dust particles can easily enter the housing 91 and adhere to the filter screen 97 after the outlet 98 is exposed to air for a long time, affecting its use, this invention provides a protective mechanism 99. When impurities are above the outlet 98, the second motor 92 is activated. The output of the second motor 92 reverses, driving the gear shaft 93 to reverse, which in turn drives the first gear 94 to reverse, which in turn drives the second one-way gear 991 to rotate. The rotation of the second one-way gear 991 then drives the rotating rod 992 to rotate, which in turn drives the second gear 993 to rotate. The rotation of the second gear 993 then drives the toothed plate 994 to rotate, which in turn drives the guide rod 995 and the sealing plate 996 to rotate, releasing the seal on the outlet 98. After the impurities are discharged through the outlet 98, the output of the second motor 92 continues to reverse, causing the sealing plate 996 to rotate back to its original position. The restored sealing plate 996 then seals the outlet 98.
[0063] It achieves the function of dust protection for filter screen 97, and can seal or unseal the outlet 98 through sealing plate 996, effectively preventing particulate dust from adhering to the surface of filter screen 97 and affecting its use.
[0064] like Figure 8 and Figure 9As shown, the fixing mechanism 997 includes a second spring 9971, a locking block 9972, a second sliding rod 9973, and a connecting rod 9974. Two second springs 9971 are symmetrically fixedly connected to one side surface of the toothed plate 994. One end of each second spring 9971 is fixedly connected to a locking block 9972. Both locking blocks 9972 are engaged with the sealing plate 996. A second sliding rod 9973 is fixedly connected to one side surface of each locking block 9972. The second spring 9971 is sleeved on the outer surface of the second sliding rod 9973. Both locking blocks 9972 and the second sliding rod 9973 are slidably connected to the toothed plate 994. One end of each second sliding rod 9973 is fixedly connected to the connecting rod 9974.
[0065] To address the issue of wear and aging that easily occurs with long-term use of the sealing plate 996, this invention provides a fixing mechanism 997. When replacing the sealing plate 996, the connecting rod 9974 is pulled, which moves the second sliding rod 9973. The movement of the second sliding rod 9973 then causes the locking block 9972 to separate from the sealing plate 996, allowing the sealing plate 996 to be removed. The new sealing plate 996 is then inserted into the guide rod 995. When the sealing plate 996 contacts the locking block 9972, the locking block 9972 moves towards the second spring 9971. After the sealing plate 996 contacts the toothed plate 994, the elastic force of the second spring 9971 causes the locking block 9972 to move and engage with the sealing plate 996, thus fixing the sealing plate 996.
[0066] It enables quick disassembly and assembly of the 996 sealing plate, is simple to operate, and facilitates the replacement of the 996 sealing plate.
[0067] like Figure 3 and Figure 8 As shown, the output end of the first motor 74 and the rotating shaft 75, and the output end of the second motor 92 and the gear shaft 93 are all fixedly connected by a coupling 10. When the first motor 74 or the second motor 92 starts, the coupling 10 provides overload protection for the rotating shaft 75 or the gear shaft 93.
[0068] Instructions for use: Start the first motor 74 to move the screening screen 77 up and down to achieve a vibration effect. Then open the cover plate 73, add granular fertilizer into the box 71, and then screen it through the vibrating screening screen 77. Smaller particles fall to the bottom of the box 71, while larger particles remain on the screening screen 77.
[0069] Start the material pump 81, and the smaller particles at the bottom of the box 71 enter the mixing tank 2. At the same time, the water filtered by the filter screen 97 enters the mixing tank 2 through the water inlet pipe 6 to dissolve the smaller particles of fertilizer. After the smaller particles of fertilizer are dissolved, the fertilizer solution is discharged through the liquid outlet pipe 3 for wheat irrigation and fertilization.
[0070] When a large amount of impurities accumulate, the output of the second motor 92 rotates forward, causing the rotating plate 96 to rotate and the filter screen 97 to rotate 180°. The impurities then rotate to the top of the impurity outlet 98. Then, the output of the second motor 92 rotates in reverse, causing the sealing plate 996 to rotate, releasing the seal on the impurity outlet 98. The impurities are discharged through the impurity outlet 98. At the same time, the impurities are filtered through another filter screen 97. After the impurities are discharged, the output of the second motor 92 rotates in reverse, causing the sealing plate 996 to rotate back to its original position and seal the impurity outlet 98.
[0071] When the smaller granular fertilizer is used up, turn the handwheel 710 to move the baffle 78 away from the screening screen 77 to a suitable position. The larger granular fertilizer on the screening screen 77 falls into the lower part of the box 71 through the space between the screening screen 77 and the baffle 78, and is then used as larger granular fertilizer.
[0072] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
