Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a drip irrigation system for preventing and controlling bacterial wilt and root rot in peanuts. Background Technology

[0002] Bacterial wilt and root rot are two common and serious diseases in peanut cultivation. Although they have some similarities in the conditions for their occurrence, the specific conditions are different. For example, the conditions for the occurrence of both bacterial wilt and root rot are related to factors such as temperature, humidity and soil environment. However, bacterial wilt is more serious when the temperature is high and the humidity is high, while root rot is more likely to occur when the soil is heavy and sticky.

[0003] In existing peanut cultivation, drip irrigation is usually used to ensure water utilization efficiency. Water, nutrients, and pesticides are dripped evenly and slowly into the soil around the peanut roots through a pipeline system and drip nozzles installed on capillary tubes.

[0004] While existing drip irrigation systems can deliver water, nutrients, and pesticides into the peanut root zone, this method remains inefficient. Nutrients and pesticides drip with the water, and the location of the drips is difficult to change, which is not conducive to the prevention of bacterial wilt and root rot, nor to the treatment of peanut diseases after they occur. Summary of the Invention

[0005] To address the above shortcomings, this invention provides a drip irrigation system for the prevention and control of peanut bacterial wilt and root rot, which solves the problem that existing drip irrigation systems are not conducive to the prevention and control of peanut bacterial wilt and root rot due to the fixed drip irrigation location.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A drip irrigation system for preventing and controlling bacterial wilt and root rot in peanuts includes a water pump, a main pipe connected to the water pump, a branch pipe connected to the main pipe, and multiple drip irrigation units. Each drip irrigation unit includes a drip irrigation frame and drip nozzles. The drip irrigation frame has multiple drip nozzle mounting positions along its height. The drip nozzles are detachably mounted on the drip nozzle mounting positions of the drip irrigation frame so that the drip nozzles can be installed at different heights on the drip irrigation frame. The drip nozzles are connected to the branch pipes via flexible hoses.

[0007] Furthermore, the drip irrigation frame includes vertical inserts on both sides and a horizontally arranged crossbar located between the vertical inserts. There are multiple crossbars distributed at different heights of the vertical inserts. The crossbar has a receiving groove to form the drip nozzle mounting position. The receiving groove is opened from the side of the crossbar inward and passes through the top and bottom of the crossbar. The side of the crossbar has a horizontally arranged transverse groove that passes through the receiving groove. The side of the drip nozzle is provided with a limiting block. The drip nozzle is received and installed in at least one receiving groove, and the limiting block of the drip nozzle is located in the transverse groove.

[0008] Furthermore, the crossbar has multiple receiving slots, which are arranged along the length of the crossbar.

[0009] Furthermore, the receiving groove is provided with spring pieces on opposite sides of the groove opening.

[0010] Furthermore, the vertical insertion rod includes a lower insertion rod and an upper insertion rod, which are nested together to be axially compressible and have an elastic element at the connection point to allow them to return to their original position when compressed. One horizontal bar is connected to the lower insertion rod, and the remaining horizontal bars are connected to the upper insertion rod. The drip tip includes an outer sleeve and a drip tip body. The drip tip body is fitted inside the outer sleeve, with a portion of its bottom extending out of the outer sleeve and capable of axial sliding within it. A water outlet is provided on the bottom sidewall of the drip tip body, and this outlet is covered when the outer sleeve slides towards the bottom of the drip tip body. A through groove is provided axially on the sidewall of the outer sleeve. Both the outer sleeve and the drip tip body are provided with limiting blocks, and multiple limiting blocks on the drip tip body pass through the through groove of the outer sleeve.

[0011] Furthermore, the limiting block is disposed on both sides opposite to the outer sleeve and the drip tip body.

[0012] Furthermore, a water inlet pipe is provided inside the drip tip body along its axial direction, the top of the water inlet pipe is connected to a flexible hose, and the water outlet is connected to the water inlet pipe.

[0013] Furthermore, the water outlet is radially disposed on the bottom side wall of the dripper body, and the bottom of the water inlet pipe is lower than the water outlet.

[0014] Furthermore, the drip irrigation system for preventing and controlling bacterial wilt and root rot in peanuts also includes a controller, a solenoid valve, and an image recognition device. The solenoid valve is installed between each drip irrigation unit and the connected branch pipe. The image recognition device is used to identify peanut plants. The controller is electrically connected to the solenoid valve and the image recognition device respectively, and controls the solenoid valve of the drip irrigation unit at the corresponding plant position according to the image recognition results.

[0015] Furthermore, it also includes a limiting member, which is used to limit the lower and upper insert rods to remain in a compressed state when the lower insert rod and the upper insert rod are compressed against each other to drive the outer sleeve to cover the water outlet of the drip nozzle body.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the drip irrigation system of the present invention for preventing and controlling bacterial wilt and root rot of peanuts can change the position of the entire drip irrigation unit and the position of the drip nozzles. By changing the position, depth, etc., the drip irrigation position and method can be changed, thereby achieving the prevention and control of bacterial wilt and root rot.

Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Please refer to Figures 1 to 7 A preferred embodiment of the present invention provides a drip irrigation system for preventing and controlling bacterial wilt and root rot in peanuts. The drip irrigation system mainly includes a water pump 10, a main pipe 20 connected to the water pump 10, branch pipes 30 connected to the main pipe 20, and a drip irrigation unit 40. The water pump 10 is used to deliver water, nutrients, and pesticides into the main pipe 20. The main pipe 20 distributes the water, nutrients, and pesticides in the main pipe 20 into each branch pipe 30. The drip irrigation unit 40 is connected to the branch pipes 30, and the water, nutrients, and pesticides delivered into the branch pipes 30 are drip-irrigated through the drip irrigation unit 40.

[0024] The drip irrigation system includes multiple storage tanks 50. These tanks 50 can store water for drip irrigation and can also be used to dilute nutrients and pesticides for delivery with the water. The storage tanks 50 are connected to a water pump 10 via pipes. Valves are installed on the pipes connecting the pump 10 and the storage tanks 50, and the opening and closing of these valves controls the water supply to the different storage tanks 50. Similarly, valves are installed between the main pipe 20 and the branch pipes 30 to adjust the water supply to each branch pipe 30.

[0025] The system includes multiple drip irrigation units 40. The number and location of the drip irrigation units 40 should be selected according to the actual location requiring drip irrigation. In this exemplary embodiment, each branch pipe 30 is distributed along the direction of peanut planting. If peanuts are ridged, the branch pipes 30 are distributed along the direction of the ridges, and the branch pipes 30 are not placed on the ground, but at a certain height above the ground. Multiple connectors are provided on each branch pipe 30 along its extension direction.

[0026] The drip irrigation unit 40 includes a drip irrigation frame 41 and drip nozzles 42. The drip nozzles 42 are installed on the drip irrigation frame 41, which is inserted into the ground where peanuts are planted. At this time, the drip nozzles 42 are temporarily fixed in a certain position. The drip nozzles 42 are connected to the branch pipe 30 through a flexible tube, specifically through a connector on the branch pipe. In practice, water, nutrients, pesticides, etc. delivered by the branch pipe 30 drip through the drip nozzles 42 onto the ground or into the ground to achieve drip irrigation. It can be understood that this drip irrigation can be for normal watering and fertilization of peanuts, or for pesticide drip irrigation when peanuts are diseased or need corresponding treatment.

[0027] Multiple dripper mounting positions are provided along the height of the drip irrigation frame 41. The drippers 42 are detachably installed on the dripper mounting positions of the drip irrigation frame 41 so that the drippers 42 can be installed at different heights of the drip irrigation frame 41. On the one hand, when the drippers 42 are installed at different heights of the drip irrigation frame 41, when the drip irrigation frame 41 is inserted into the ground where peanuts are planted, the drippers 42 will be in different positions, such as the dripper position 42 being in contact with the ground, or the drippers 42 being inserted into the ground together with the drip irrigation frame 41. The drip irrigation unit 40 is connected to the branch pipe 30 through a flexible tube, and the position of the drip irrigation unit 40 can be changed, that is, the position of the drip irrigation frame 41 and the drippers 42 can also be changed. By changing the position, depth, etc., the drip irrigation position and method can be changed, thereby achieving the prevention and control of bacterial wilt and root rot. Traditional drip irrigation is a fixed system, where water, nutrients, and pesticides are always dripped at a specific location in contact with the ground. If sufficient nutrients or pesticides need to be delivered to the peanut roots, a certain amount of water needs to be dripped, which can easily lead to high humidity and heavy, sticky soil. However, with the drip irrigation system of this invention, the position of the drip irrigation unit 40 and the depth of the drip nozzle 42 can be adjusted. When sufficient nutrients or pesticides need to be delivered to the peanut roots, the drip nozzle 42 is inserted into the soil close to the roots. In this case, the drip irrigation is only applied near the peanut roots, resulting in less water consumption and reducing the likelihood of high humidity and heavy, sticky soil. This effectively prevents bacterial wilt and root rot. Similarly, the treatment of bacterial wilt and root rot is also effective. Some diseases only require drip irrigation at a certain distance from the peanut plant, while some pesticides can be dripped directly to the roots. The drip irrigation system of this invention allows for adjustment of the drip irrigation position by changing the position of the drip irrigation unit 40 and the drip nozzle 42.

[0028] In a preferred embodiment, the system further includes a controller, a solenoid valve, and an image recognition device. The solenoid valve is installed between each drip irrigation unit 40 and the connected branch pipe 30. In this exemplary embodiment, a lead pipe can be extended from the branch pipe 30, which is connected to the drip nozzle 42 on the drip irrigation unit 40 via a flexible hose. In this case, the solenoid valve is installed on the lead pipe, and the dripping volume of the corresponding drip nozzle 42 on the drip irrigation unit 40 can be adjusted by adjusting the opening degree of the solenoid valve. Peanut plants suffering from bacterial wilt and root rot are clearly distinguishable from healthy plants in appearance. Therefore, they can be identified using an image recognition device. The controller is electrically connected to both the solenoid valve and the image recognition device. The image recognition device is used to photograph the peanut plants, and the photographic information is transmitted to the controller. The controller judges the image information from the image recognition device. When it determines that the image information of a certain group of peanut plants corresponds to diseased plants, it controls the solenoid valve of the drip irrigation unit 40 at the corresponding plant location to reduce the opening of the solenoid valve or directly close the solenoid valve. At this time, the drip irrigation amount for the corresponding plant is reduced or eliminated, thereby reducing the soil moisture content at the corresponding location and helping to alleviate and assist in the treatment of bacterial wilt and root rot. The drip irrigation system of the present invention for the prevention and control of peanut bacterial wilt and root rot can determine whether peanut plants are diseased through image recognition and promptly control the drip irrigation amount after disease onset to facilitate the alleviation and treatment of diseased plants. The drip irrigation volume is controlled by the corresponding drip irrigation unit 40, which enables precise control of the drip irrigation volume for different areas. This allows for accurate control of the drip irrigation volume for diseased plants without affecting the drip irrigation of other healthy plants.

[0029] The drip irrigation frame 41 includes vertical inserts 411 on both sides and a horizontal bar 412 positioned between the vertical inserts 411. The vertical inserts 411 are inserted into the ground, and the drip irrigation frame 41 can be temporarily held in a certain position. It can be understood that a horizontal circular disc is fixedly installed at a certain height of the vertical inserts 411. When the vertical inserts 411 are inserted into the ground, the disc contacts the ground, and the vertical inserts 411 are inserted to the specified depth, ensuring that the insertion depth is in place.

[0030] Multiple crossbars 412 are distributed at different heights on the vertical insert 411. Each crossbar 412 has a receiving groove 413 to form a drip tip mounting position. The drip tip 42 can be installed at different heights on different crossbars 412. The receiving groove 413 extends inward from the side of the crossbar 412 and passes through its top and bottom. The drip tip 42 enters the receiving groove 413 from the side. Each receiving groove 413 has a spring piece 415 on opposite sides of its opening. The spring piece 415 acts as a limit at the opening to prevent the drip tip 42 from falling out during use. When installing or removing the drip tip 42, pressing the spring piece 415 deforms it, allowing the drip tip 42 to pass through the opening of the receiving groove 413. During use, the spring piece 415 remains in place at the opening.

[0031] A transverse groove 414 is provided on the side of the crossbar 412, which transversely passes through the receiving groove 413. A limiting block 421 is provided on the side of the dropper 42. The dropper 42 is received and installed in at least one receiving groove 413, and the limiting block 421 of the dropper 42 is located within the transverse groove 414. The dropper 42 has a cylindrical rod-like structure and is received and installed in at least one receiving groove 413. Depending on the placement position of the dropper 42, it can be received in multiple receiving grooves 413, such as... Figure 3 As shown, the drip tip 42 is located at the lower position of the drip holder 41, at which point the drip tip 42 is accommodated within the two receiving slots 413, and as... Figure 2 As shown, the drip tip 42 is located at a higher position on the drip irrigation frame 41, and at this time, the drip tip 42 is accommodated in the three receiving slots 413. The limiting block 421 of the drip tip 42 is located in the horizontal groove 414. The limiting block 421 and the horizontal groove 414 limit the height position of the drip tip 42. For example, when the drip tip 42 is inserted into the ground along with the drip irrigation frame 41, the limiting block 421 and the horizontal groove 414 prevent the drip tip 42 and the drip irrigation frame 41 from shifting to each other, ensuring that the drip tip 42 can be inserted into the ground to a certain depth along with the drip irrigation frame 41.

[0032] There are multiple receiving slots 413 on the crossbar 412, which are arranged along the length of the crossbar 412. This means that multiple receiving slots 413 are used to hold multiple droppers 42. It is understood that the multiple receiving slots 413 on different crossbars 412 are aligned vertically, ensuring that droppers 42 can be placed simultaneously in the receiving slots 413 of different crossbars 412. It is also understood that not every receiving slot 413 located along different lengths of the crossbar 412 needs to hold a dropper 42; the number, position, and spacing of the droppers 42 can be selected according to actual use.

[0033] In a preferred embodiment, the vertical insertion rod 411 includes a lower insertion rod 4111 and an upper insertion rod 4112. The lower insertion rod 4111 and the upper insertion rod 4112 are nested together to be axially compressible, and an elastic element 4113 is provided at the connection to ensure that the lower insertion rod 4111 and the upper insertion rod 4112 tend to return to their original position when compressed. More specifically, the top of the lower insertion rod 4111 has a cavity in which the elastic element 4113 is placed. The elastic element 4113 is selected as a compression spring. One end of the upper insert rod 4112 is inserted into the top cavity of the lower insert rod 4111 and abuts against the elastic element 4113. Therefore, when the upper insert rod 4112 is pressed, the elastic element 4113 is compressed. At this time, the lower insert rod 4111 and the upper insert rod 4112 are axially compressed against each other. For example, when the vertical insert rod 411 is inserted into the ground, during the insertion of the lower insert rod 4111 into the ground, the upper insert rod 4112 simultaneously compresses the elastic element 4113 and moves towards the lower insert rod 4111. One horizontal bar 412 is connected to the lower insert rod 4111, and the other two horizontal bars 412 are connected to the upper insert rod 4112. The bottom of the lower insert rod 4111 is conical to facilitate insertion into the ground.

[0034] The dropper 42 includes an outer sleeve 422 and a dropper body 423. The dropper body 423 is fitted inside the outer sleeve 422, with a portion of its bottom extending out of the outer sleeve 422 and capable of axially sliding within the outer sleeve 422. A water outlet hole 425 is provided on the bottom side wall of the dropper body 423, and the water outlet hole 425 is covered when the outer sleeve 422 slides towards the bottom of the dropper body 423. A through groove 424 is provided axially on the side wall of the outer sleeve 422. Limiting blocks 421 are provided on both the outer sleeve 422 and the dropper body 423, and there are two limiting blocks 421 on the dropper body 423 that pass through the through groove 424 of the outer sleeve 422.

[0035] When implementing, you can refer to Figure 2 or Figure 3The drip tip 42 is placed in the receiving groove 413. The limiting block 421 of the outer sleeve 422 and the horizontal groove 414 of the cross bar 412 of the upper insertion rod 4112 mutually limit each other, while the limiting block 421 of the drip tip body 423 and the horizontal groove 414 of the cross bar 412 of the lower insertion rod 4111 mutually limit each other. When the drip irrigation frame 41 is inserted into the ground, pressing the cross bar on the outer sleeve 422 or the upper insertion rod 4112 compresses the elastic element 4113 of the upper insertion rod 4112. The nozzle moves downwards towards the insertion rod 4111. Simultaneously, under the mutual limiting action of the limiting block 421 of the outer sleeve 422 and the transverse groove 414 of the crossbar 412 of the upper insertion rod 4112, and the mutual limiting action of the limiting block 421 of the nozzle body 423 and the transverse groove 414 of the crossbar 412 of the lower insertion rod 4111, the outer sleeve 422 slides axially within the outer sleeve 422 and covers the water outlet 425. At this time, under the blocking action of the outer sleeve 422, the nozzle is isolated as much as possible. Soil is prevented from entering the water outlet 425 during insertion to avoid clogging and affecting the drip irrigation effect. After insertion, the crossbar or upper insertion rod 4112 on the outer sleeve 422 is released, and the lower insertion rod 4111 is inserted into the ground. At this time, under the action of the elastic element 4113, the upper insertion rod 4112 returns to its original position, and the limiting block 421 of the outer sleeve 422 and the transverse groove 414 of the crossbar 412 of the upper insertion rod 4112 are engaged. The dripper body 423 and the lower insert rod 4111's crossbar 412 are mutually positioned, with the limiting block 421 of the dripper body 423 and the crossbar 414 of the lower insert rod 4111 mutually limiting each other. At this time, the dripper body 423 is relatively fixed to the lower insert rod 4111, while the outer sleeve 422 is relatively fixed to the upper insert rod 4112. During the upward reset of the upper insert rod 4112, the outer sleeve 422 is pulled upward, thus removing the cover from the water outlet 425 and allowing normal water flow from the water outlet 425. This invention prevents soil from entering the water outlet 425 during insertion and removes the cover after insertion, effectively preventing soil from clogging the water outlet 425 and affecting the drip irrigation effect.

[0036] In a preferred embodiment, the drip irrigation system for preventing and controlling peanut bacterial wilt and root rot further includes a limiting member. The limiting member is used to keep the lower insert rod 4111 and the upper insert rod 4112 in a compressed state when the outer sleeve 422 covers the water outlet 425 of the dripper body 423. By keeping the outer sleeve 422 covering the water outlet 425 of the dripper body 423, the water outlet 425 can be kept covered even when the dripper 42 is inserted into the ground but not dripping, so as to prevent soil from entering the water outlet 425.

[0037] Understandably, in order to facilitate the outer sleeve 422 covering the water outlet 425 of the dripper body 423 when the lower insert 4111 and the upper insert 4112 are compressed against each other, it is preferable that: firstly, the bottom of the lower insert 4111 is preferably lower than the bottom of the dripper body 423; secondly, the water outlet 425 of the dripper body 423 is a certain distance from the bottom of the dripper body 423; and thirdly, the dripper body 423 should be as close as possible to the bottom of the outer sleeve 422.

[0038] Limiting blocks 421 are provided on opposite sides of the outer sleeve 422 and the dropper body 423. Correspondingly, through grooves 424 on the side wall of the outer sleeve 422 are also provided on opposite sides.

[0039] The dripper body 423 has a water inlet pipe 426 arranged axially inside. The top of the water inlet pipe 426 is connected to a flexible hose, and the outlet hole 425 is connected to the water inlet pipe 426. Water, nutrients, and chemicals from the branch pipe 30 enter the water inlet pipe 426 through the flexible hose and then exit from the outlet hole 425 to achieve drip irrigation. The outlet hole 425 is radially located on the bottom side wall of the dripper body 423. The bottom of the water inlet pipe 426 is lower than the outlet hole 425, thus forming a space at the bottom of the water inlet pipe 426 to accommodate soil entering the bottom of the water inlet pipe 426. Even if soil enters, it can be stored at the bottom of the water inlet pipe 426 without affecting the connection between the water inlet pipe 426 and the outlet hole 425, ensuring smooth water flow.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
