Description

Technical Field

[0001] The invention relates to the technical field of irrigation devices, in particular to an irrigation device for a tobacco seedling greenhouse. Background Art

[0002] In the irrigation operation of tobacco seedling greenhouses, traditional irrigation devices usually use fixed nozzles for irrigation. Although this method is simple to operate, it has many defects. First, the fixed nozzles cannot be flexibly adjusted according to the growth and density of the tobacco seedlings, resulting in a limited irrigation range and many blind areas of spraying. Some tobacco seedlings may not get enough water and nutrients, affecting their normal growth. Secondly, traditional irrigation devices are also insufficient in stirring the mixed liquid. The mixed liquid is easy to precipitate and stratify in the cylinder, making the nutrient composition of the irrigation liquid unbalanced and unable to meet the demand for nutrient diversity of tobacco seedlings. In addition, continuous spraying or excessive spraying not only wastes water resources and fertilizers, but may also cause over-irrigation of tobacco seedlings, affecting their root respiration and growth.

[0003] In order to overcome these defects of traditional irrigation devices, some improved tobacco seedling greenhouse irrigation devices are currently on the market. These devices achieve more uniform irrigation and mixing of the mixed liquid by adding a stirring component and adjusting the swing of the nozzle. However, these improved devices still have some problems in practical applications. For example, the design of the stirring component is not precise enough, resulting in unsatisfactory mixing effect of the mixed liquid in the cylinder, and precipitation and stratification still exist.

[0015] Compared with the prior art, it has the following beneficial effects:

[0016] The precise design of the stirring assembly ensures that the mixed liquid is evenly distributed in the cylinder. The reciprocating swing of the stirring rod is combined with the up and down movement of the sleeve rod and the connecting frame to form a multi-dimensional stirring effect, which effectively prevents the precipitation and stratification of the mixed liquid and ensures that every drop of irrigation liquid contains balanced nutrients. The control component controls the swing of the spray component, which makes the irrigation range wider and the coverage more uniform, improves the irrigation efficiency, and ensures that the tobacco seedlings can obtain sufficient and uniform water and nutrients.

[0017] The start-up of the drive motor causes the worm, worm wheel, second gear and other transmission parts to rotate synchronously, thereby driving the rotating rod and the movable rod to swing back and forth. This swing not only expands the irrigation range, but also ensures that the irrigation liquid can evenly cover the tobacco seedlings, reduces the spraying blind area, and improves the spraying efficiency; the up and down swing design of the nozzle enables the spray liquid to be accurately sprayed on tobacco seedlings of different heights and densities. This dynamic spraying method is more flexible and efficient than fixed nozzles, and can better meet the tobacco seedlings' needs for water and nutrients.

[0018] The fan gear drives the driven gear to reciprocate as the U-shaped frame swings, thereby driving the spline shaft, sleeve rod, connecting frame, stirring rod and other stirring components to reciprocate synchronously. This reciprocating rotation ensures the uniform stirring of the mixed liquid in the cylinder and effectively prevents the precipitation and stratification of the mixed liquid. The up and down movement design of the connecting plate further enhances the stirring effect by compressing and releasing the damping spring, making the mixed liquid more uniform. This design not only improves the stirring efficiency, but also extends the service life of the stirring component.

[0019] By precisely controlling the swing speed and amplitude of the sprinkler nozzle, the spraying range and intensity of the sprinkler can be precisely adjusted. This flexibility makes the sprinkler more precise and avoids the waste of water and fertilizer caused by continuous or excessive sprinkler spraying. Compared with traditional irrigation methods, this device achieves more efficient use of water and fertilizer through dynamic sprinkler spraying and precise control, which helps to reduce production costs while reducing the impact on the environment.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. 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 making creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: Combination Figure 1-Figure 9As shown, the present invention provides a technical solution: an irrigation device for a tobacco seedling greenhouse, comprising a cylinder 1, a liquid inlet pipe 2 is connectedly arranged on the side wall of the cylinder 1, and is used to introduce liquid into the cylinder 1. The cylinder 1 is provided with a stirring component 4 for stirring the mixed liquid to ensure the uniformity of the mixed liquid. In addition, spray components 3 for irrigating tobacco seedlings are respectively arranged on both sides of the top of the cylinder 1. These spray components 3 can swing to achieve a wider irrigation range. In order to control the swing of the spray components 3, control components 5 are also arranged on both sides of the top of the cylinder 1. The control components 5 are responsible for adjusting the swing action of the spray components 3;

[0032] The stirring assembly 4 is composed of multiple parts, including a spline shaft 41 rotatably mounted in the cylinder 1, a first base 48 is fixedly connected to the bottom of the spline shaft 41 to ensure its stability, a sleeve rod 42 is slidably connected to the upper and lower ends of the outer wall of the spline shaft 41, and a connecting frame 43 is arranged in a circumferential array on the outer wall of the sleeve rod 42. The connecting frame 43 is provided with stirring arms in the vertical direction for stirring the mixed liquid inside the cylinder 1. These stirring arms can effectively mix the liquid in the cylinder 1 to ensure the uniformity of the mixed liquid;

[0033] The stirring rod 44 is rotatably mounted on the connecting frame 43 through the positioning shaft 412. A slide groove 45 is provided on the side of the stirring rod 44 close to the spline shaft 41. A slide shaft 413 is slidably connected in the slide groove 45. All slide shafts 413 are connected by a transmission rod 46. A vertical rod 47 slidably mounted on the connecting frame 43 is fixedly connected at the bottom of the transmission rod 46. The bottom of the vertical rod 47 is fixedly connected to the first base 48, thereby ensuring the overall stability of the stirring assembly 4.

[0034] A damping spring 49 sleeved on the spline shaft 41 is provided between the first base 48 and the lower sleeve rod 42. The damping spring 49 can absorb vibration and reduce the noise generated during the operation of the equipment. A driven gear 410 is fixedly connected to the top of the spline shaft 41, and a connecting plate 411 is fixedly connected to the top of the upper sleeve rod 42. These components work together to ensure that the stirring assembly 4 can operate efficiently and stably.

[0035] In the embodiment of the present invention, by precisely controlling the movement of the assembly 5, the driven gear 410 meshing therewith can be driven to reciprocate in positive and negative directions. This reciprocating movement mode enables the driven gear 410 to effectively drive the spline shaft 41 to rotate synchronously, and the rotation of the spline shaft 41 further drives the sleeve rod 42, the connecting frame 43 and the stirring rod 44 to rotate synchronously. This linkage mechanism ensures that the connecting frame 43 and the stirring rod 44 can reciprocate in a coordinated manner. Through this reciprocating rotation, the mixed liquid in the cylinder 1 is effectively stirred, thereby preventing the mixed liquid from precipitating in the cylinder 1, which is crucial to maintaining the optimal effect of the mixed liquid on the tobacco seedlings.

[0036] During the rotation of the spline shaft 41, the control component 5 is also responsible for pushing the connecting plate 411 to move downward. This action causes the connecting plate 411 to apply pressure to the sleeve rod 42 and the connecting frame 43, causing them to move downward and compress the damping spring 49. When the control component 5 stops applying downward force to the connecting plate 411, the elastic force of the damping spring 49 will push the sleeve rod 42 and the connecting frame 43 to move upward and return to the initial position. While the connecting frame 43 reciprocates up and down, the stirring rod 44 swings back and forth up and down under the joint action of the vertical rod 47, the transmission rod 46 and the slide 45. This swing further enhances the stirring effect, making the mixed liquid more uniform. During the mixing process, the vertical rod 47 and the transmission rod 46 play a key transmission role, which ensure that the stirring rod 44 can swing according to a predetermined trajectory, thereby improving the stirring efficiency and the uniformity of the mixed liquid. In addition, the design of the slide 45 not only provides a stable swinging track for the stirring rod 44, but also ensures the stability and reliability of the entire stirring mechanism. Through this carefully designed transmission and stirring mechanism, the irrigation device for the tobacco seedling greenhouse can achieve uniform stirring of the mixed liquid, effectively prevent the occurrence of precipitation of the mixed liquid, thereby ensuring the best effect of the mixed liquid on the tobacco seedlings. At the same time, the device has a simple structure and is easy to operate, which greatly improves the efficiency and quality of tobacco seedling cultivation.

[0037] Embodiment 2: Combination Figure 3As shown, on the basis of the first embodiment, the spray assembly 3 includes a swing rod 31 rotatably mounted on the control assembly 5, and a nozzle 32 is arranged at the other end of the swing rod 31 for uniformly spraying the liquid to the target area. A pump body 35 is fixedly mounted on the side wall of the cylinder 1, and an extraction pipe 36 is arranged at the input end of the pump body 35. The other end of the extraction pipe 36 extends to the inside of the cylinder 1 to ensure that the liquid in the cylinder 1 can be effectively extracted. The output end of the pump body 35 is fixedly connected to a delivery pipe 34, and the other end of the delivery pipe 34 is connected to a telescopic hose 33. When the cylinder 1 is swung, the telescopic hose 33 can be driven to perform corresponding telescopic processing to adapt to different spraying angles and ranges. The other end of the telescopic hose 33 is connected to the nozzle 32 to form a flexible spraying system. When the tobacco seedlings need to be irrigated, the operator only needs to turn on the pump body 35, and the pump body 35 will use the extraction pipe 36 to extract the mixed liquid in the cylinder 1. Then, the mixed liquid is transported to the nozzle 32 by the delivery pipe 34 and the telescopic hose 33. Finally, the nozzle 32 sprays the mixed liquid evenly on the tobacco seedlings to ensure that each tobacco seedling can get an appropriate amount of water and nutrition.

[0038] In the embodiment of the present invention, during the process of irrigating the tobacco seedlings, the pump body 35 needs to be started first, and the pump body 35 draws the mixed liquid from the barrel 1 through the extraction pipe 36. Then, the mixed liquid is transported to the nozzle 32 by using the delivery pipe 34 and the telescopic hose 33. Finally, the mixed liquid is evenly sprayed onto the tobacco seedlings through the nozzle 32 to ensure that the plants can get sufficient water and nutrients.

[0039] Example 3: Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, on the basis of the second embodiment, the design of the control component 5 includes a second base 51, which is fixedly mounted on the top of the cylinder 1, and a rotating rod 52 is rotatably connected to the top of the second base 51, and the top of the rotating rod 52 is fixedly connected to a U-shaped frame 53, and a driving motor 54 is installed on the U-shaped frame 53, and the output end of the driving motor 54 is fixedly connected to a worm 56, and one end of the worm 56 is fixedly connected to a pressure rod 517;

[0040] A positioning plate 57 is also fixedly connected to the top of the second base 51, and a movable rod 58 is rotatably connected to the positioning plate 57. The other end of the movable rod 58 is rotatably connected to a rotating rod 59, and the other end of the rotating rod 59 is provided with a rotating shaft 510, and a mounting frame 511 and a gear 512 are provided on the rotating shaft 510. One end of the gear 512 is rotatably connected to a second gear 513 and a worm wheel 514. The second gear 513 is meshed with the gear 512, and the worm 56 is transmission-connected with the worm wheel 514. By turning on the driving motor 54, the worm 56 can be driven to rotate synchronously, and then the worm 56 drives the worm wheel 514 to rotate, and the rotation of the worm wheel 514 makes the second gear 513 rotate synchronously. Rotate, the second gear 513 drives the meshed mounting frame 511 and the rotating shaft 510, so that the rotating rod 59 is driven to rotate through the rotating shaft 510, and the rotating rod 59 is used to drive the movable rod 58 to reciprocate at the connection point between the movable rod 58 and the positioning plate 57. This reciprocating swing further drives the U-shaped frame 53, the driving motor 54, the worm 56, the pressure rod 517, the worm wheel 514, the second gear 513, the rotating shaft 510, the mounting frame 511, and the gear 512 to reciprocate synchronously. This synchronous reciprocating swing further drives the swing rod 31 and the sprinkler head 32 to reciprocate, thereby expanding and evenly irrigation range.

[0041] The bottom of the U-shaped frame 53 is provided with a sector gear 515 meshing with the driven gear 410, and a Y-shaped frame 516 slidably mounted on the top of the cylinder 1 is provided in the sector gear 515. The bottom of the Y-shaped frame 516 contacts the top of the connecting plate 411, and one end of the pressure rod 517 is located in the Y-shaped frame 516. A cross bar 518 is fixedly connected to one side of the Y-shaped frame 516. The cross bar 518 is slidably mounted on the second base 51, and one end is fixedly connected to an arc plate 519. The surface of the arc plate 519 is opened with the rotating rod 52 as the axis. An arc groove 520 is provided, and a mounting seat 55 is provided at one end of the U-shaped frame 53 close to the nozzle 32. One end of the swing rod 31 is rotatably mounted on the mounting seat 55. The bottom end of the swing rod 31 is rotatably connected to a linkage rod 521. The bottom end of the linkage rod 521 is rotatably connected to a slide seat 522. The slide seat 522 is slidably mounted in the arc groove 520. When the pressure rod 517 reciprocates with the U-shaped frame 53, the pressure rod 517 can slide in the Y-shaped frame 516, so that the swinging pressure rod 517 can drive the Y-shaped frame 516 to move downward. The downward movement of the Y-shaped frame 516 can drive the cross bar 518, the arc plate 519 and the connecting plate 411 to move downward. When the cross bar 518 and the arc plate 519 move downward, the arc plate 519 moves downward through the arc groove 520, the slide seat 522 and the connecting rod 521, thereby driving the swing rod 31 and the nozzle 32 to rotate downward. As the pressure rod 517 swings and resets, it can drive the swing rod 31 and the nozzle 32 to rotate upward. The up and down swing of the nozzle 32 can ensure that the spray liquid covers the tobacco seedlings more evenly. This dynamic spray Compared with the fixed nozzle 32, the spraying method can better adapt to tobacco seedlings of different heights and densities, reduce the blind area of ​​spraying, and improve the spraying efficiency. By controlling the swing speed and amplitude of the nozzle 32, the spraying range and intensity of the spray liquid can be adjusted. This flexibility makes the spraying more accurate and can better meet the needs of tobacco seedlings for water and nutrients. Compared with continuous spraying or excessive spraying, spraying by controlling the swing of the nozzle 32 can more effectively utilize water resources and fertilizers, which helps to reduce production costs and reduce the impact on the environment.

[0042] When the connecting plate 411 moves downward, it can push the sleeve rod 42, the connecting frame 43, and the stirring rod 44 to move downward and compress the damping spring 49. As the pressure rod 517 swings and resets, the sleeve rod 42, the connecting frame 43, and the stirring rod 44 are pushed upward and reset under the elastic force of the damping spring 49. In this way, the connecting frame 43 and the stirring rod 44 are controlled to move up and down, thereby further enhancing the stirring effect and making the mixed liquid more uniform.

[0043] In the embodiment of the present invention, by starting the driving motor 54, the synchronous rotation of the worm 56 can be achieved, and the rotation of the worm 56 drives the rotation of the worm wheel 514, so that the worm wheel 514 can drive the rotation of the second gear 513, and the second gear 513 is engaged with the mounting frame 511 and the rotating shaft 510. Through the rotation of the rotating shaft 510, the rotating rod 59 is rotated, and the rotating movement of the rotating rod 59 is used to drive the movable rod 58 to reciprocate around the connection point with the positioning plate 57. This swinging motion is further transmitted to the U-shaped frame 53, the driving motor 54, the worm 56, the pressure rod 517, the worm wheel 514, the second gear 513, the rotating shaft 510, the mounting frame 511, and the gear 512, so that they swing back and forth synchronously. The swinging motion also affects the swing rod 31 and the sprinkler head 32, thereby expanding and uniforming the irrigation range. At the same time, when the pressure rod 517 swings back and forth with the U-shaped frame 53, it can slide in the Y-shaped frame 516, causing the Y-shaped frame 516 to move downward. The descent of the frame 516 drives the cross bar 518, the arc plate 519 and the connecting plate 411 to move downward together. When the cross bar 518 and the arc plate 519 move downward, they cooperate with the arc groove 520, the slide seat 522 and the connecting rod 521 to further promote the swing rod 31 and the nozzle 32 to rotate downward. As the pressure rod 517 swings back to its original position, the swing rod 31 and the nozzle 32 can rotate upward. The up and down swing of the nozzle 32 ensures that the spray liquid evenly covers the tobacco seedlings. This dynamic spraying method is better than the fixed spraying method. The nozzle 32 can better adapt to tobacco seedlings of different heights and densities, reduce blind areas of spraying, and improve spraying efficiency. By adjusting the swing speed and amplitude of the nozzle 32, the spraying range and intensity of the spraying liquid can be accurately controlled. This flexibility makes spraying more accurate and can better meet the needs of tobacco seedlings for water and nutrients. Compared with continuous spraying or excessive spraying, spraying by controlling the swing of the nozzle 32 can more effectively utilize water resources and fertilizers, which helps to reduce production costs and reduce environmental impact;

[0044] When the U-shaped frame 53 reciprocates, the sector gear 515 also oscillates, and drives the driven gear 410 meshing therewith to reciprocate. The rotation of the driven gear 410 is used to drive the spline shaft 41, the sleeve rod 42, the connecting frame 43, and the stirring rod 44 to reciprocate.

[0045] When the connecting plate 411 moves downward, it pushes the sleeve rod 42, the connecting frame 43, and the stirring rod 44 to move downward and compress the damping spring 49. When the pressure rod 517 swings and resets, under the elastic force of the damping spring 49, the sleeve rod 42, the connecting frame 43, and the stirring rod 44 will move upward and reset. In this way, the up and down movement of the connecting frame 43 and the stirring rod 44 is precisely controlled, thereby further enhancing the stirring effect and ensuring that the mixed liquid is more uniform.

[0046] Working principle of irrigation device for tobacco seedling greenhouse:

[0047] Step 1: When the device is moved to a suitable position, the pump body 35 is turned on, and the pump body 35 uses the extraction pipe 36 to extract the mixed liquid in the cylinder body 1, and then uses the delivery pipe 34 and the telescopic hose 33 to transport it to the nozzle 32, and then uses the nozzle 32 to spray the mixed liquid on the tobacco seedlings;

[0048] Step 2: Turn on the drive motor 54 to drive the worm 56 to rotate synchronously, and the worm 56 drives the worm wheel 514 to rotate, so that the worm wheel 514 drives the second gear 513 to rotate, and the second gear 513 drives the meshing mounting frame 511 and the rotating shaft 510, thereby driving the rotating rod 59 to rotate through the rotating shaft 510, and then using the rotating rotating rod 59, the rotating rod 59 drives the movable rod 58 to reciprocate at the connection point between the movable rod 58 and the positioning plate 57, thereby driving the U-shaped frame 53, the drive motor 54, the worm 56, the pressure rod 517, the worm wheel 514, the second gear 513, the rotating shaft 510, the mounting frame 511, and the gear 512 to reciprocate synchronously, thereby driving the swing rod 31 and the nozzle 32 to reciprocate. The pressure rod 517 can be moved to expand and even the irrigation range; at the same time, when the pressure rod 517 swings back and forth with the U-shaped frame 53, the pressure rod 517 can slide in the Y-shaped frame 516, so that the swinging pressure rod 517 can drive the Y-shaped frame 516 to move downward, so that the Y-shaped frame 516 can drive the cross bar 518, the arc plate 519 and the connecting plate 411 to move downward. When the cross bar 518 and the arc plate 519 move downward, the arc plate 519 moves downward through the arc groove 520, the slide seat 522 and the connecting rod 521, thereby driving the swing rod 31 and the nozzle 32 to rotate downward. As the pressure rod 517 swings and resets, it can drive the swing rod 31 and the nozzle 32 to rotate upward. The up and down swinging of the nozzle 32 can ensure that the spray liquid covers the tobacco seedlings more evenly.

[0049] Step 3: The mixed liquid in the cylinder 1 is stirred by the reciprocating rotation of the connecting frame 43 and the stirring rod 44, so as to prevent the mixed liquid in the cylinder 1 from settling, thereby affecting the effect of the mixed liquid on the tobacco seedlings;

[0050] Step 4: When the connecting plate 411 moves downward, the connecting plate 411 pushes the sleeve rod 42 and the connecting frame 43 to move downward and compress the damping spring 49. When the control component 5 no longer provides a downward force on the connecting plate 411, the sleeve rod 42 and the connecting frame 43 are pushed upward under the elastic force of the damping spring 49. At the same time, when the connecting frame 43 moves back and forth up and down, the stirring rod 44 swings back and forth up and down under the action of the vertical rod 47, the transmission rod 46 and the slide groove 45, thereby further enhancing the stirring effect and making the mixed liquid more uniform.
