TECHNICAL FIELD

[0001] The application relates to the technical field of breeding devices, in particular to a sweet corn breeding device capable of controlling water quantity and a use method. BACKGROUND

[0002] In the genetic breeding, strain screening and trait identification research of sweet corn, water is one of the most critical environmental factors affecting the growth and development of sweet corn. Cultivating new varieties with excellent traits (such as high sugar content, good taste and strong stress resistance) requires precise comparative tests on a large number of breeding materials (different strains or genotypes) at key growth stages such as the seedling stage and the flowering stage. The uniformity and controllability of irrigation water directly affect the accuracy, reliability and repeatability of the test results. In the process of sweet corn breeding, the watering operation of breeding units and researchers mainly relies on the following traditional or semi-traditional methods. This is the most common but also the most crude method. The operator uses a water pipe, a watering can or a watering bucket and other tools for flooding or spraying. This method has many inherent defects. It completely depends on the experience and responsibility of the operator. It is difficult to unify the amount and speed of watering. There may be significant differences in the actual amount of water received between different batches and even different breeding units (pots, plants) of the same batch. Fatigue, negligence or replacement of the operator may lead to uneven watering, introducing huge test errors, causing soil compaction, seed or seedling washing and making it difficult to ensure uniform water distribution in the soil profile. For large-scale breeding populations, manual watering is a heavy and time-consuming physical labor.

[0011] This invention provides a sweet corn breeding device with controllable irrigation volume. It has the following beneficial effects: 1. This controllable watering sweet corn breeding device is equipped with a first motor. The drive shaft of the first motor rotates, driving a hollow screw to rotate. The rotation of the hollow screw drives the extrusion base to move. The extrusion base moves along the spiral guide bar via a sliding groove, thereby driving the extrusion base to rotate. As the extrusion base rises along the hollow screw, it extrudes the liquid, which then enters the spraying device for spraying. The position of the extrusion base is fixed by the threaded engagement between the hollow screw and the screw sleeve, facilitating quantitative spraying. When water is injected through the water inlet, the water flows in along the water inlet and descends under the action of gravity. The water flows along the guide hole into the mixing tank, and the downward rotation of the extrusion base drives the stirring blades to agitate the water flow, facilitating the mixing of the water and fertilizer. Under the heating action of the heating rod, heat is transferred along the extrusion base, facilitating the melting of fertilizer, etc.

[0012] 2. This controllable watering sweet corn breeding device is equipped with an elbow inlet. Water is introduced along the elbow and enters the water supply pipe. The water then enters the spray pipe and, under the pressure of the squeezing base, enters the spray pipe and squeezes the fixed plug. The fixed plug slides along the sliding plug, facilitating water spraying. As the fixed plug slides along the sliding plug, it descends, causing the spring to compress and generate elastic force. This allows the fixed plug and sliding plug to re-engage when the water flow stops, facilitating sealing. The elbow design also concentrates air at the top of the elbow during water delivery, preventing air from entering the spray pipe. Furthermore, the downward guiding design of the water supply pipe facilitates separation of the delivered water from the water inside the mixing tank, preventing repeated spraying during water intake.

[0013] 3. This controllable watering sweet corn breeding device is equipped with a rotating seat. When adjusting the water pressure, the rotating seat is rotated via a torsion groove. The rotation of the rotating seat drives the sliding screw to rotate, which in turn drives the adjusting plate to rise. The rising of the adjusting plate compresses the spring, thereby increasing the elastic force of the fixed plug on the sliding plug, thus facilitating the adjustment of the water pressure. This change in water pressure allows for adjustments to the spray area. The torsion groove and threaded pipe on the side of the rotating seat limit the rising range of the rotating seat and prevent it from loosening, ensuring the stability of the water pressure. The water flows along the inside of the spray pipe, into the inside of the water delivery pipe, and then into the inside of the rotating joint. The water flows out along the nozzle, and the reaction force of the water flow from the nozzle drives the rotating joint to rotate, thereby causing the nozzle to cover different angles, thus facilitating irrigation.

[0014] 4. This sweet corn breeding device with controllable water volume is equipped with a fixed base plate, which supports the heat preservation tank and is fixed to the ground by a fixing rod. The height of the heat preservation tank is raised by a limiting plate, which facilitates the suspension and fixation of the heat preservation tank, thereby facilitating the expansion of the coverage area and making it easier to irrigate the seedlings.

[0016] 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.

[0017] For the first embodiment, please refer to... Figures 1-3 The present invention provides a technical solution: a sweet corn breeding device with controllable watering volume, including an insulated tank 1, a conveying device 2 fixedly connected to the inner wall of the insulated tank 1, a water inlet connector 3 connected to the top of the conveying device 2, a spraying device 4 connected to the top of the conveying device 2, and a fixing frame 5 fixedly connected to the bottom of the insulated tank 1.

[0018] The insulated tank 1 insulates the conveying device 2. The conveying device 2 holds the liquid and drives and squeezes it, thereby driving the liquid into the spraying device 4 for spraying. The water inlet connector 3 replenishes the inside of the conveying device 2, allowing for repeated use. The fixed frame 5 raises the position of the insulated tank 1, thereby facilitating the expansion of the coverage area of ​​the spraying device 4 and making it easier to spray and irrigate the seedlings.

[0019] The conveying device 2 includes a mixing tank 201. A guide top 202 is fixedly connected to the top of the inner wall of the mixing tank 201. A first motor 203 is fixedly connected to the top of the mixing tank 201. A hollow screw 204 is fixedly connected to the drive shaft of the first motor 203. A heating rod 205 is fixedly connected to the inner wall of the hollow screw 204 through a bracket. A spiral guide 206 is fixedly connected to the side of the inner wall of the mixing tank 201. An extrusion assembly 207 is sleeved and threaded onto the side of the hollow screw 204. The side of the mixing tank 201 is fixedly connected to the inner wall of the heat preservation tank 1. The top of the mixing tank 201 is connected to the bottom of the water inlet connector 3.

[0020] The extrusion assembly 207 includes an extrusion base 2071. A threaded sleeve 2072 is fixedly connected to the top of the inner wall of the extrusion base 2071. A guide groove 2073 is provided on the side of the threaded sleeve 2072. A stirring groove 2074 is provided on the top of the extrusion base 2071. An agitator blade 2075 is fixedly connected to the side of the inner wall of the stirring groove 2074. A guide hole 2076 is provided on the inner wall of the stirring groove 2074. A sliding groove 2077 is provided on the side of the extrusion base 2071. A hollow screw 204 passes through the inner wall of the threaded sleeve 2072 and is threadedly connected to the hollow screw 204. The extrusion base 2071 is slidably connected to the spiral guide bar 206 through the sliding groove 2077.

[0021] The first motor 203 is started, and the drive shaft of the first motor 203 rotates, driving the hollow screw 204 to rotate. The rotation of the hollow screw 204 causes the extrusion base 2071 to move. The extrusion base 2071 moves along the spiral guide 206 via the sliding groove 2077, thereby driving the extrusion base 2071 to rotate. As the extrusion base 2071 rises along the hollow screw 204, it extrudes the liquid, thus allowing it to enter the spraying device 4 for spraying. The extrusion base is achieved through the threaded engagement between the hollow screw 204 and the screw sleeve 2072. The position of 2071 is fixed, which facilitates quantitative spraying. When water is injected through the water inlet connector 3, the water flows along the water inlet connector 3 and descends under the action of gravity. The water flows along the guide hole 2076 and enters the interior of the mixing tank 2074. During the descent and rotation of the extrusion base 2071, the stirring blades 2075 drive the water flow to stir, which facilitates the mixing of water and fertilizer. Under the heating action of the heating rod 205, the heat is transferred along the extrusion base 2071, which facilitates the melting of fertilizer, etc.

[0022] Second embodiment, please refer to Figures 1-5Based on the first embodiment, the present invention provides a technical solution: the pressure regulating component of the spraying device 4 includes a water supply pipe 401, the top of the water supply pipe 401 is connected to an elbow pipe 402, the bottom of the water supply pipe 401 is connected to a spraying pipe 403, the inner wall of the spraying pipe 403 is fixedly connected to a pressure regulating component 404, the side of the spraying pipe 403 is connected to a spraying component 405, and the end of the elbow pipe 402 away from the water supply pipe 401 is connected to the top of the mixing tank 201.

[0023] The pressure regulating assembly 404 includes a fixed plug 4041, a sliding plug 4042 that is sleeved and slidably connected to the top of the fixed plug 4041, a spring 4043 that is fixedly connected to the bottom of the fixed plug 4041, a sliding screw 4044 that is slidably connected to the bottom of the fixed plug 4041, an adjusting plate 4045 that is sleeved and threadedly connected to the side of the sliding screw 4044, the top of the adjusting plate 4045 that contacts the bottom of the spring 4043, an adjusting assembly 4046 that is fixedly connected to the bottom of the sliding screw 4044, and the sliding plug 4042 that is disposed inside the spray pipe 403 and fixedly connected to the inner wall of the spray pipe 403.

[0024] Water is introduced along the elbow pipe 402 and enters the water supply pipe 401. The water then enters the spray pipe 403 and, under the pressure of the squeezing base 2071, enters the spray pipe 403 and squeezes the fixed plug 4041. The fixed plug 4041 slides along the sliding plug 4042, facilitating water flow into the spray assembly 405 for spraying. As the fixed plug 4041 slides along the sliding plug 4042, it descends, causing the spring 4043 to move. The compression causes the spring 4043 to generate elastic force, which facilitates the re-engagement of the fixed plug 4041 and the sliding plug 4042 when the water flow stops, thus facilitating sealing. At the same time, the bend of the elbow pipe 402 facilitates the concentration of air at the top of the elbow pipe 402 during water flow, thereby preventing air from entering the interior of the spray pipe 403. The downward guiding design of the water supply pipe 401 facilitates the separation of the water flow delivered from the water flow inside the mixing tank 201, thus facilitating separation and preventing repeated spraying of water during water intake.

[0025] Third embodiment, please refer to Figures 1-7Based on the second embodiment, the present invention provides a technical solution: the adjustment component 4046 includes a rotating seat 40461, a threaded groove 40462 is provided on the side of the rotating seat 40461, a torsion groove 40463 is provided on the bottom of the rotating seat 40461, a threaded tube 40464 is sleeved and threadedly connected to the side of the rotating seat 40461, a connecting plate 40465 is fixedly connected to the top of the threaded tube 40464, the top of the rotating seat 40461 is fixedly connected to the bottom of the sliding screw 4044, the sliding screw 4044 passes through the top of the connecting plate 40465 and is slidably connected to the connecting plate 40465, and the top of the connecting plate 40465 is fixedly connected to the bottom of the spray pipe 403.

[0026] The spraying assembly 405 includes a water supply pipe 4051, one end of which is connected to a rotary joint 4052, the bottom of which is connected to a nozzle 4053, and the end of the water supply pipe 4051 away from the rotary joint 4052 is connected to the side of the spraying pipe 403.

[0027] When adjusting the water pressure, the rotating seat 40461 is rotated via the torsion groove 40463. The rotation of the rotating seat 40461 drives the sliding screw 4044 to rotate, which in turn drives the adjusting plate 4045 to rise. The rising of the adjusting plate 4045 compresses the spring 4043, thereby increasing the elastic force of the fixed plug 4041 on the sliding plug 4042. This facilitates the adjustment of the water pressure, thereby changing the water pressure and thus the spray area. The torsion groove 404 on the side of the rotating seat 40461 further facilitates this adjustment. The setting of 63 and threaded pipe 40464 limits the rising range of rotating seat 40461 and prevents rotating seat 40461 from loosening, thereby ensuring the stability of water pressure. Water flows along the inside of spray pipe 403 into the inside of water supply pipe 4051 and into the inside of rotary joint 4052. Water flows out along nozzle 4053. The reaction force of water flow when it sprays out of nozzle 4053 drives rotary joint 4052 to rotate, thereby driving nozzle 4053 to cover different angles, thus facilitating irrigation.

[0028] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 Based on the third embodiment, the present invention provides a technical solution: the fixing frame 5 includes a fixing base plate 501, a fixing rod 502 is fixedly connected to the side of the fixing base plate 501, a limiting plate 503 is fixedly connected to the side of the fixing rod 502 at a position below the fixing base plate 501, and the top of the fixing base plate 501 is fixedly connected to the bottom of the heat preservation tank 1.

[0029] The base plate 501 supports the heat preservation tank 1, and the fixing rod 502 fixes it to the ground. The limiting plate 503 raises the height of the heat preservation tank 1, which makes it easier to suspend and fix the heat preservation tank 1, thereby facilitating the expansion of the coverage area and making it easier to irrigate the seedlings.

[0030] For the fifth embodiment, please refer to... Figures 1-9 Based on the fourth embodiment, the present invention provides a technical solution: a method for using a sweet corn breeding device with controllable irrigation amount, comprising the following steps: S1. Start the first motor 203. The drive shaft of the first motor 203 rotates, which drives the hollow screw 204 to rotate. The rotation of the hollow screw 204 drives the extrusion base 2071 to move. The extrusion base 2071 extrudes the liquid, which then enters the spraying device 4 for spraying. The water flow is injected along the water inlet connector 3 and enters the mixing tank 2074 along the guide hole 2076. S2. Water is introduced along the elbow pipe 402, and enters the interior of the water delivery pipe 401 along the elbow pipe 402. Water enters the interior of the spray pipe 403. When the fixed plug 4041 slides along the sliding plug 4042, the water is easily separated from the water inside the mixing tank 201 by the downward guiding design of the water delivery pipe 401. S3. The torsion groove 40463 rotates the rotating seat 40461. The rotation of the rotating seat 40461 drives the sliding screw 4044 to rotate. The rotation of the sliding screw 4044 drives the adjusting plate 4045 to rise. The rise of the adjusting plate 4045 compresses the compression of the spring 4043. The water flow is sprayed out along the nozzle 4053. The reaction force of the water flow sprayed out of the nozzle 4053 drives the rotary joint 4052 to rotate. S4. The fixed base plate 501 supports the heat preservation tank 1, and the fixed rod 502 fixes it to the ground. The limiting plate 503 raises the height of the heat preservation tank 1, so as to facilitate the suspension and fixation of the heat preservation tank 1, thereby facilitating the expansion of the coverage area and making it easier to irrigate the seedlings.

9. A method of using a sweet corn breeding device with controllable irrigation volume, characterized in that, Includes the following steps: S1. Start the first motor. The drive shaft of the first motor rotates, which drives the hollow screw to rotate. The rotation of the hollow screw drives the extrusion base to move. The extrusion base extrudes the liquid, which then enters the spraying device for spraying. The water is injected along the water inlet connector and enters the mixing tank along the guide hole. S2. Water is introduced along the elbow pipe, enters the interior of the water delivery pipe, and enters the interior of the spray pipe. When the fixed plug slides along the sliding plug, the water flow is easily separated from the water flow inside the mixing tank by the downward guiding design of the water delivery pipe. S3. The rotating seat of the twisting groove rotates, and the rotation of the rotating seat drives the sliding screw to rotate. The rotation of the sliding screw drives the adjusting plate to rise. The rise of the adjusting plate compresses the spring, and the water flow is sprayed out along the nozzle. The reaction force of the water flow when it is sprayed out of the nozzle drives the rotating joint to rotate. S4. The base plate supports the insulation tank and is fixed to the ground by the fixing rod. The height of the insulation tank is raised by the limiting plate, so that the insulation tank can be suspended and fixed, thereby facilitating the expansion of the coverage area and making it easier to irrigate the seedlings.
