Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery and equipment, and in particular to an agricultural fertilization sprinkler irrigation device and method. Background Art

[0002] The process of sprinkler fertilization is to dissolve fertilizer in irrigation water and then spray the fertilizer out together with the irrigation water through a spray device. In the actual fertilization process, the sprinkler device can be used to apply fertilizer to the crops' leaves or roots according to the crop's planting density, growth stage, and crop type. Sprinkler fertilization using a sprinkler device has the advantages of high fertilizer utilization rate and fertilizer saving.

[0003] Chinese patent CN116134994B discloses a fertilization sprinkler device, including a support cylinder, a plug cone fixedly connected to the bottom of the support cylinder, an adjustment cylinder threadedly connected to the upper inner wall of the support cylinder, an adjustment rod fixedly connected to the outer wall of the adjustment cylinder, a mounting shell fixedly connected to the top of the adjustment cylinder, and a sprinkler assembly arranged above the mounting shell. When the control clamping plate contacts the arc-shaped protruding block, the control clamping plate will slowly move upward, during which the corrugated adjustment wall will be compressed, the outlet of the upper limit sprinkler head will become smaller, and the pressure at the outlet will increase, thereby increasing the distance that water or water fertilizer is sprayed from the outlet of the upper limit sprinkler head, and increasing the coverage of the upper limit sprinkler head during irrigation.

[0004] The fertilization sprinkler device announced in the above prior art increases the distance that water and fertilizer are sprayed from the water outlet by changing the size of the water outlet, thereby increasing the irrigation range. At the same time, by adjusting the direction of the water outlet, the irrigation can be made more uniform. However, the fertilization sprinkler device announced in the above prior art has limitations, because it is very important to choose a suitable fertilization method according to the planting density, growth stage and crop type of crops, which can not only give full play to the effectiveness of fertilizers, but also improve the absorption efficiency of fertilizers by crops. Foliar fertilization or root fertilization is usually used, while the fertilization sprinkler device announced in the above announcement can only perform foliar fertilization by sprinkler irrigation, and cannot perform root fertilization. When it is necessary to fertilize the roots of crops, the sprinkler device needs to be replaced, and the operation is relatively cumbersome. In addition, when the fertilization sprinkler device announced in the above announcement encounters strong winds during the sprinkler irrigation process, the strong wind will blow away part of the water and fertilizer sprayed out, so that the water and fertilizer are blown to places outside the crops, which will not only cause uneven sprinkler irrigation, but also cause waste of water and fertilizer.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In order to solve the technical problems that agricultural fertilization sprinkler devices cannot adapt to crops of different heights and cannot sprinkle crops with different planting spacings, such as Figure 1-5 As shown, the following preferred technical solutions are provided:

[0046] An agricultural fertilization sprinkler device comprises a gantry 1 and a traveling assembly 2 fixedly arranged at the lower end of the gantry 1. The gantry 1 supports and fixes many parts, and the traveling assembly 2 is used to realize the forward, backward and steering of the agricultural fertilization sprinkler device. A placement assembly 3 is arranged at the middle of the upper end of the gantry 1. A mixing box 4 and an air pump 5 are fixedly installed on the top surface of the placement assembly 3. The air pump 5 is connected to the mixing box 4 through an air pipe 20. The air pump 5 can pressurize the water and fertilizer in the mixing box 4. A grinding assembly 6 is arranged on the mixing box 4. A fertilizer box 7 is fixedly installed, and a communication arrangement is made between the fertilizer box 7 and the mixing box 4. A valve is provided at the connection between the mixing box 4 and the fertilizer box 7. After the valve is opened, the fertilizer in the fertilizer box 7 will pass through the valve and fall onto the grinding assembly 6. After the grinding assembly 6 grinds the fertilizer into fine powder, the powdered fertilizer will fall into the mixing box 4 and mix with the irrigation water in the mixing box 4 to form water-fertilizer. The purpose of grinding the fertilizer into powder is to increase the solubility of the fertilizer in the irrigation water and prevent agglomeration from occurring, which may cause blockage of the agricultural fertilization sprinkler. When there is enough fertilizer in the mixing box 4, the valve can be closed.

[0047] A lifting assembly 8 is provided on the top surface of the inner cavity of the gantry 1, and a plurality of sprinkler assemblies 9 are slidably provided on the lifting assembly 8. The plurality of sprinkler assemblies 9 are connected to the mixing box 4 through water pipes 30, respectively. A windproof assembly 10 is provided on the sprinkler assemblies 9. The setting of the lifting assembly 8 can drive the sprinkler assemblies 9 and the windproof assembly 10 to move up and down. When foliar fertilization is performed on crops, such a setting can adjust the appropriate sprinkler height, and sprinkler irrigation can be performed on crops at different heights. In addition to foliar fertilization, root fertilization can also be achieved. During the process of foliar fertilization, if there is a sudden strong wind, the strong wind will blow away part of the water and fertilizer sprayed out and fall outside the crops, which will not only cause uneven spraying, but also cause the problem of waste of water and fertilizer. The windproof component 10 can rotate with the wind and always maintain a position perpendicular to the wind. At this time, the water and fertilizer blown away by the strong wind will be blocked by the windproof component 10, and the flying water and fertilizer will fall on the side wall of the windproof component 10. After the strong wind stops, the water and fertilizer on the side wall of the windproof component 10 are washed away with water and collected, which can be reused, reducing the waste of water and fertilizer.

[0048] The placement component 3 includes a load-bearing plate 32 fixedly installed in the middle of the top surface of the gantry 1. The load-bearing plate 32 is fixedly connected to the side wall of the gantry 1 through a plurality of pairs of support frames 31. The air pump 5 and the mixing box 4 are both fixedly installed on the top surface of the load-bearing plate 32.

[0049] The mixing box 4 includes a box body 41 and a water valve 42 connected to the outer walls on both sides of the box body 41. The box body 41 is connected to the fertilizer box 7, and a valve is provided at the connection between the box body 41 and the fertilizer box 7. The box body 41 and the air pump 5 are connected through the air pipe 20, and the water valve 42 and the sprinkler assembly 9 are connected through the water pipe 30. The air pump 5 pressurizes the water and fertilizer inside the box body 41, and the pressurized water and fertilizer will enter the sprinkler assembly 9 through the water pipe 30, and finally be sprayed out from the sprinkler assembly 9 to irrigate the crops.

[0050] The grinding assembly 6 includes a first grinding roller 61 and a second grinding roller 62 which are respectively rotatably mounted in the inner cavity of the box body 41. The outer peripheral walls of the first grinding roller 61 and the second grinding roller 62 are in contact with each other. A driving gear 63 is fixedly sleeved on one end of the first grinding roller 61 away from the air pump 5, and a driven gear 64 is fixedly sleeved on one end of the second grinding roller 62 away from the air pump 5. The driving gear 63 and the driven gear 64 are both arranged outside the box body 41, and the driving gear 63 and the driven gear 64 are meshed and connected. A motor 65 is fixedly mounted on the side wall of the box body 41. The output end of the motor 65 is fixedly connected to the driving gear 63. When fertilizer is added to the box body 41, the motor 65 is started to run. The motor 65 drives the first grinding roller 61 and the second grinding roller 62 to rotate through the driving gear 63 and the driven gear 64. At this time, the valve at the connection between the box body 41 and the fertilizer box 7 is opened, and the fertilizer will flow from the fertilizer box 7 to the first grinding roller 61 and the second grinding roller 62. The first grinding roller 61 and the second grinding roller 62 grind the fertilizer into powdered fertilizer, the purpose of which is to improve the solubility of the fertilizer in the irrigation water.

[0051] The lifting assembly 8 includes a plurality of first electric telescopic columns 81 fixedly mounted on the top surface of the inner cavity of the gantry 1, the lower ends of the plurality of first electric telescopic columns 81 are commonly connected to a flat plate 82, a plurality of through slide grooves 83 are provided on the flat plate 82, the sprinkler assembly 9 is slidably mounted in the inner cavity of the through slide grooves 83, a second electric telescopic column 84 is fixedly mounted on the side wall of the inner cavity of the through slide grooves 83, and the extended end of the second electric telescopic column 84 is fixedly connected to the side wall of the sprinkler assembly 9.

[0052] Specifically, when using an agricultural fertilization sprinkler to irrigate crops, it is necessary to determine whether to use foliar fertilization or root fertilization based on the planting density, growth stage, and crop type of the crops. In addition, the planting density of different types of crops is inconsistent. Therefore, the planting row spacing of different types of crops is inconsistent. Before sprinkler irrigation, the extension length of the first electric telescopic column 81 is adjusted according to the height of the crops to control the sprinkler assembly 9 at a suitable sprinkler height. Then, according to the planting spacing of the crops, the extension length of the second electric telescopic column 84 is adjusted to drive the sprinkler assembly 9 to slide in the inner cavity of the slide groove 83 until the spacing between two adjacent sprinkler assemblies 9 is adapted to the planting spacing. The second electric telescopic column 84 stops running. At this time, the crops can be sprinkled. Through the above-mentioned settings, the agricultural fertilization sprinkler can not only adapt to crops of different heights, but also can sprinkle crops with different planting spacings.

[0053] In order to solve the technical problems that the traditional agricultural fertilization sprinkler can not sprinkle directly under the soil, and the water outlet 9512 will be blocked when sprinkler is sprinkled under the soil, such as Figure 1-2 and Figure 5-9 As shown, the following preferred technical solutions are provided:

[0054] The sprinkler assembly 9 includes a water and fertilizer inlet 91 that is slidably installed in the inner cavity of the through-slide groove 83 and a circular chamber 92 that is connected and fixedly installed on the bottom surface of the water and fertilizer inlet 91. The upper end of the water and fertilizer inlet 91 is connected to the water valve 42 through a water pipe 30. A connecting pipe 93 is fixedly installed on the bottom surface of the circular chamber 92. A plug block 94 is fixedly installed on the lower end of the connecting pipe 93. A telescopic nozzle 95 is slidably installed inside the plug block 94.

[0055] The plug block 94 includes a plug block body 941, a first channel 942 is vertically opened inside the plug block body 941, and a pair of second channels 943 are horizontally opened inside the plug block body 941. The two second channels 943 are connected to the first channel 942 respectively, and the upper end of the first channel 942 is connected to the lower end of the connecting pipe 93. The inner cavities of the two second channels 943 are respectively embedded with telescopic nozzles 95 slidably installed.

[0056] The telescopic nozzle 95 includes a shell 951 embedded and slidably installed in the inner cavity of the second channel 943, the shell 951 and the side wall of the inner cavity of the second channel 943 are elastically arranged by a first spring 952, a through hole 953 is opened on the side wall of the shell 951, the second channel 943 and the inner cavity of the shell 951 are connected by the through hole 953, and a pressure relief valve is arranged in the inner cavity of the through hole 953, a sealing block 954 is embedded and slidably installed in the inner cavity of the shell 951, and the sealing block 954 and the side wall of the inner cavity of the shell 951 are elastically connected by a second spring 955.

[0057] The blocking block 954 includes a blocking block body 9541 embedded and slidably installed in the inner cavity of the shell 951, and a number of deep grooves 9542 are opened on the outer walls on both sides of the blocking block body 9541. The inner cavities of the several deep grooves 9542 are respectively slidably installed with snap-in blocks 9543, and the snap-in blocks 9543 are elastically connected to the side walls of the inner cavity of the deep groove 9542 through a third spring 9544.

[0058] The outer shell 951 includes a shell 9511 embedded and slidably installed in the inner cavity of the second channel 943. A plurality of water outlets 9512 are opened on the outer walls on both sides of the shell 9511. The clamping blocks 9543 are correspondingly clamped in the inner cavities of the water outlets 9512.

[0059] Specifically, further, when fertilizing the roots of crops, the first electric telescopic column 81 is started to drive the sprinkler assembly 9 to move downward until the lower end of the plug block 94 is inserted into the soil. The first electric telescopic column 81 stops extending and is positioned. At this time, the air pump 5 is started to pressurize the water and fertilizer in the box body 41. The pressurized water and fertilizer will flow through the water valve 42, the water pipe 30, the water and fertilizer inlet 91, the circular chamber 92 and the connecting pipe 93 into the first channel 942, and then enter the inner cavity of the second channel 943. When the water pressure is greater than the elastic force of the first spring 952, the shell 951 will extend the blocking block 954 toward the soil outside the second channel 943. When the shell 951 moves to the farthest distance, the water pressure continues to increase. When When the water pressure exceeds the threshold value set by the pressure relief valve, the water and fertilizer will enter the inner cavity of the shell 951 from the through hole 953, and will generate thrust on the blocking block 954. When the thrust reaches a certain level, the clamping block 9543 will shrink into the inner cavity of the deep groove 9542, thereby releasing the clamping relationship between the clamping block 9543 and the water outlet 9512. At this time, the blocking block body 9541 continues to extend outward, so that the water outlet 9512 becomes a passage state, and the water and fertilizer in the inner cavity of the shell 951 will be sprayed from the water outlet 9512 to the surrounding soil, thereby spraying the crops. The above-mentioned setting is to insert the sprinkler assembly 9 into the soil for irrigation. Through such a setting, it is not only beneficial to the absorption of nutrients by the roots of crops, but also can improve the utilization rate of water and fertilizer.

[0060] Furthermore, when the sprinkler irrigation is finished, the air pump 5 is turned off to reduce the water pressure. Under the elastic force of the second spring 955, the blocking block body 9541 will retract into the inner cavity of the shell 951. When the clamping block 9543 moves to the position of the water outlet 9512, under the elastic force of the third spring 9544, the clamping block 9543 will extend into the inner cavity of the water outlet 9512 to block the water outlet 9512, preventing soil from entering the inner cavity of the shell 951 and causing blockage. At the same time, under the elastic force of the first spring 952, the shell 951 retracts into the inner cavity of the second channel 943 with the blocking block 954. At this time, the first electric telescopic column 81 is shortened upward, and the lower end of the plug 94 is pulled out of the soil. After moving forward an appropriate distance through the traveling component 2, the above steps are repeated to achieve sprinkler irrigation again.

[0061] In order to solve the technical problem that water and fertilizer are blown away from crops during strong winds during sprinkler irrigation, which not only causes uneven sprinkler irrigation but also wastes water and fertilizer, such as Figure 1-2 and Figure 9-12 As shown, the following preferred technical solutions are provided:

The second permanent magnet 1043 and the first permanent magnet 1033 are arranged in corresponding positions. A pair of pressing blocks 1042 are embedded in the second plate body 1041. The pressing blocks 1042 and the positioning holes 1032 can form a corresponding snap-fitting relationship. When there is no wind, the pressing blocks 1042 are pressed to release the snap-fitting relationship between the pressing blocks 1042 and the positioning holes 1032. Under the magnetic force of the second permanent magnet 1043 and the first permanent magnet 1033, the second wind shield 104 slides upward as a whole, and then the length of the lifting rod 101 is shortened, so that the wind shield component 10 is retracted upward. Such a setting not only saves space, but also does not affect the operation of fertilizing the roots of crops. When it is windy, only the above steps need to be reversed.

[0066] Specifically, when strong winds are encountered during the process of spraying crops, because the components of the windproof assembly 10 are all made of lightweight materials, when the wind blows the wind deflector 106, the lifting rod 101 will carry the windproof assembly 10 as a whole to rotate in the inner cavity of the circular slide groove 922. Since the wind deflector 106 is always parallel to the wind direction, and since the wind deflector 106 is vertically arranged to the first wind deflector 103 and the second wind deflector 104, the first wind deflector 103 and the second wind deflector 104 are always vertical to the wind direction. When strong winds are encountered, the strong winds will blow away part of the water and fertilizer sprayed out, and this part of the water and fertilizer blown away will be blocked by the first wind deflector 103 and the second wind deflector 104. 04 is designed in an arc shape, and the water and fertilizer blown onto the first wind shield 103 and the second wind shield 104 will gather in the middle of the inner wall of the first wind shield 103 and the second wind shield 104, and will flow into the collection box 105 for collection under the action of gravity. When the strong wind ends, the inner wall of the first wind shield 103 and the second wind shield 104 is flushed with water, and finally discharged from the recovery port 107, and the part of the water and fertilizer blown away is recycled, thereby reducing the waste of water and fertilizer. Through the above-mentioned arrangement, no matter what the wind direction is, the first wind shield 103 and the second wind shield 104 can block and collect the blown water and fertilizer, and can prevent the phenomenon of excessive water and fertilizer spraying on some crops during strong winds, causing damage to the crops.

[0067] In order to further better explain the above embodiment, the present invention also provides an implementation scheme, an agricultural fertilization sprinkler irrigation method, comprising the following steps:

[0068] Step 1: Select the mode, which includes foliar fertilization and root fertilization.

[0069] Step 2: When applying fertilizer to the leaves, adjust the extension length of the first electric telescopic column 81 according to the height of the crops, control the sprinkler assembly 9 at a suitable sprinkler height, and adjust the extension length of the second electric telescopic column 84 until the spacing between two adjacent sprinkler assemblies 9 is adapted to the planting spacing.

[0070] Step three: transport the fertilizer in the fertilizer box 7 to the grinding assembly 6 for grinding. The ground powdered fertilizer is dissolved and mixed in the mixing box 4. After the dissolution is completed, start the air pump 5 to pressurize the water and fertilizer in the mixing box 4. The pressurized water and fertilizer then enter the sprinkler assembly 9 through the water pipe 30 for sprinkler irrigation, and start the moving assembly 2 to move forward for sprinkler irrigation.

[0071] Step 4: When strong winds occur, adjust the windproof assembly 10 to an appropriate height. After the strong winds stop, fold the windproof assembly 10 upwards.

[0072] Step 5: Switch the mode to root fertilization.

[0073] Step 6: Adjust the extension length of the second electric telescopic column 84 until the distance between two adjacent sprinkler assemblies 9 is adapted to the planting distance.

[0074] Step 7: Adjust the extension length of the first electric telescopic column 81 to drive the sprinkler assembly 9 to be inserted under the soil, start the air pump 5 to pressurize the water and fertilizer in the mixing box 4, and the pressurized water and fertilizer then enter the sprinkler assembly 9 through the water pipe 30 to perform sprinkler irrigation under the soil. After the sprinkler irrigation is completed, control the first electric telescopic column 81 to retract upward, pull the sprinkler assembly 9 out of the soil, and then start the traveling assembly 2 to move forward, and repeat the above process.
