Description

Technical Field

[0001] This utility model belongs to the field of strawberry planting technology, and in particular relates to a strawberry drip irrigation device. Background Technology

[0002] To meet the growing environment requirements of strawberries and ensure that they can be eaten even in winter, strawberry cultivation now typically involves growing them in greenhouses.

[0003] For example, Chinese patent CN214413722U discloses a drip irrigation device for strawberry cultivation, including a water supply pipe with a square cross-section, a hanging frame, a water delivery pipe, a telescopic pipe, a drip pipe, and a stainless steel corrugated pipe. Multiple sliding hanging frames are installed on the water supply pipe, and the water delivery pipe is fixed to the bottom of each hanging frame. Several telescopic pipes are evenly fixed to the bottom of the water delivery pipe, and the bottom of each telescopic pipe is connected to the drip pipe. The middle of the water delivery pipe is connected to the water supply pipe via a stainless steel corrugated pipe. This drip irrigation device for strawberry cultivation, by installing a telescopic pipe between the drip pipe and the water delivery pipe, facilitates adjustment of the drip irrigation height during drip irrigation, possessing strong adaptability and adjustability. It is beneficial for directly dripping water onto the soil, greatly improving the drip irrigation effect. Furthermore, by installing sliding hanging frames on the water supply pipe and fixing the water delivery pipe to the hanging frames, it is easy to quickly adjust the spacing between the water delivery pipes. The overall structure is simple, flexible, and extremely convenient to use.

[0004] The aforementioned patent has the following problems:

[0005] This patent has several drawbacks in its application. For example, water is dripped directly onto the soil through a drip pipe. The continuous dripping can easily create large puddles and expose the strawberry plant roots to the elements. In greenhouses where strawberry plants require temperatures up to 30°C, this can cause the plants to wilt. Furthermore, the constant dripping impacts and compacts the soil, increasing its hardness. This hardened topsoil hinders new root growth and lateral root expansion, limiting the strawberry plant's absorption of deeper nutrients and water. Therefore, we propose a drip irrigation device for strawberry cultivation. Utility Model Content

[0006] The purpose of this invention is to provide a drip irrigation device for strawberry cultivation to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a drip irrigation device for strawberry cultivation, comprising:

[0008] Four support pipes, each with a through groove, and a U-shaped pipe slidably installed between the four through grooves. Each U-shaped pipe has several connecting pipes inside, and several elastic spiral pipes are fixedly installed at the bottom of each connecting pipe. An insert pipe is fixedly installed at the bottom end of each elastic spiral pipe. Several water outlet holes are opened on both sides of the insert pipe near the bottom, and rotating blades are rotatably installed on both sides of the insert pipe near the bottom.

[0009] Four stirring drums are fixedly installed at the top of four support tubes respectively. At the bottom of each stirring drum and inside the support tube, a second elastic spiral tube connected to a U-shaped tube is rotatably installed.

[0010] A control component is located on four support tubes and is used to control the loop tube to be fixed on the four support tubes.

[0011] In the above technical solution, the control component further includes:

[0012] Four limiting grooves are respectively opened on four support tubes and are connected to the through grooves. A limiting rod is slidably installed in the limiting groove. One end of the limiting rod is fixedly connected to a rotating column connected to a U-shaped tube inside the support tube.

[0013] In this technical solution, when personnel need to replace the entire strawberry plant with a new variety, the U-shaped tube can be lifted and moved up the four through slots until the U-shaped tube contacts the top of the through slot. Then, the personnel hold the limiting rod and rotate it, causing the rotating column to rotate on the U-shaped tube, rotating the limiting rod into the limiting slot, ensuring that the U-shaped tube is stably fixed between the four support tubes. The second elastic spiral tube has elasticity and automatically contracts to form a spiral shape, making it easy to store the second elastic spiral tube inside the support tube. At the same time, when the insertion tube is removed from the soil, when the insertion tube is pulled down without tension, the first elastic spiral tube will also have elasticity and automatically contract to form a spiral shape, making it easy for personnel to clean the strawberry plants on the soil below the insertion tubes.

[0014] In the above technical solution, the limiting rod and the rotating column are integrally formed, the rotating column is rotatably connected to the U-shaped tube, and the limiting rod is slidably connected to the through groove.

[0015] In this technical solution, the structure of the limiting rod and the rotating column is ensured to be stable, the rotating column can rotate normally on the loop tube, and the limiting rod can move normally up and down in the through groove.

[0016] In the above technical solution, a rotating groove is further provided inside the insertion tube, a ball is rotatably installed in the rotating groove, a through hole is provided inside the ball, a handle is rotatably installed inside the insertion tube, and one end of the handle passes through one side of the insertion tube and is fixed to the ball.

[0017] In this technical solution, rotating the handle can drive the ball inside the rotating groove to rotate, so that the through hole faces the inner wall of the rotating groove, thereby ensuring that the water in the insertion tube can be disconnected. When the strawberry plant roots are short of water, the operator can rotate the handle to drive the ball to rotate, so that the insertion tube is connected to the through hole, ensuring that the liquid in the elastic spiral tube can be discharged through the insertion tube and several water outlet holes without causing impact on the soil.

[0018] In the above technical solution, the through hole is connected to the insertion tube, the diameter of the through hole is smaller than the thickness of the rotating groove, and the handle and the ball are integrally formed.

[0019] In this technical solution, water inside the insertion tube can flow through the through hole. When the through hole faces the inner wall of the rotating groove, the through hole will be sealed by the inner wall of the rotating groove, preventing the insertion tube from draining water and ensuring the structural stability of the handle and the ball.

[0020] In the above technical solution, furthermore, a chassis is fixedly installed at the bottom end of each of the four support tubes, and a motor is fixedly installed at the top of each of the four stirring drums, with the output shaft of the motor passing through the top of the stirring drum and fixedly installed with several stirring rods.

[0021] In this technical solution, it is convenient to bury the four base plates deep in the soil to ensure the structural stability of the four support pipes. With the help of the motor and several stirring rods, it is possible to put water and fertilizer into the mixing drum together, or to put pesticides or water into the mixing drum together. The output shaft of the motor drives several stirring rods to mix evenly, which can help the strawberry plants grow healthily or eliminate pests in the soil.

[0022] In the above technical solution, the output shaft of the motor is rotatably connected to the stirring drum, and the distance between the chassis and the through groove is 30-100cm.

[0023] In this technical solution, it is ensured that the motor can work normally on the mixing tank, that the chassis can be buried deeper into the soil, and that the overall structure of the device is stable.

[0024] In the above technical solution, the spiral tube and several connecting tubes are integrally formed, and the spiral tube is connected to the connecting tubes and the first elastic spiral tube, and the stirring cylinder is connected to the second elastic spiral tube and the spiral tube.

[0025] In this technical solution, the structure of the spiral tube and several connecting tubes is kept stable, ensuring that the liquid in the stirring drum can enter the insertion tube through the second elastic spiral tube, the spiral tube, the connecting tube and the first elastic spiral tube.

[0026] The beneficial effects of this utility model are:

[0027] This strawberry drip irrigation system first uses a control component to guide a loop tube to slide downwards between four slots. The loop tube also stretches the second elastic spiral tube. Then, through a mixing drum, connecting pipe, first elastic spiral tube, insert tube, water outlet, and rotating blades, the operator uses the insert tube to extend the first elastic spiral tube downwards and rotates the two rotating blades on both sides of the insert tube. Next, the bottom end of the insert tube is placed near the roots of the strawberry plant in the soil. Then, soil is covered over the bottom end of the insert tube and the two rotating blades to ensure structural stability. Finally, under gravity... Under the action of the mixing drum, the water can pass through the second elastic spiral tube, the loop tube, the connecting tube, the first elastic spiral tube, and the insertion tube, and drip into the soil near the roots of the strawberry plants through the water outlet. The water droplets slowly discharged from the water outlet will moisten the soil and provide water to the roots of the strawberry plants. The water droplets discharged through the water outlet will not cause impact on the soil, thus ensuring that the soil near the roots of the strawberry plants will not form waterlogged pits or increase soil hardness, avoiding the problem of affecting the germination of new roots and the lateral expansion of the root system, and limiting the absorption of deep nutrients and water by the strawberry plants.

[0043] Example 1:

[0044] Please see Figure 1-8 As shown in the figure, this embodiment provides a drip irrigation device for strawberry cultivation, including:

[0045] Four support pipes 1, each of which has a through groove 11. A spiral pipe 2 is slidably installed between the four through grooves 11. Several connecting pipes 3 are installed inside the spiral pipe 2. Several elastic spiral pipes 31 are fixedly installed at the bottom of the connecting pipes 3. An insert pipe 4 is fixedly installed at the bottom end of the elastic spiral pipe 31. Several water outlet holes 45 are opened on both sides of the insert pipe 4 near the bottom. Rotating blades 46 are rotatably installed on both sides of the insert pipe 4 near the bottom.

[0046] Four mixing drums 5 are fixedly installed at the top of four support pipes 1 respectively. At the bottom of the mixing drum 5 and inside the support pipe 1, an elastic spiral tube 6 connected to the loop tube 2 is rotatably installed.

[0047] The control component is located on the four support tubes 1 and is used to control the loop tube 2 to be fixed on the four support tubes 1.

[0048] First, the control component controls the U-shaped tube 2 to slide downwards between the four through slots 11. The U-shaped tube 2 also causes the elastic spiral tube 6 to be stretched. Then, through the set mixing drum 5, connecting pipe 3, elastic spiral tube 31, insertion tube 4, water outlet 45, and rotating blades 46, personnel use the insertion tube 4 to drive the elastic spiral tube 31 downwards and rotate the two rotating blades 46 on both sides of the insertion tube 4 to open them. Then, the bottom end of the insertion tube 4 is placed near the roots of the strawberry plant in the soil. Then, soil is covered over the bottom end of the insertion tube 4 and the two rotating blades 46 to ensure the structural stability of the insertion tube 4. Finally, under heavy... Under the action of force, the water in the mixing drum 5 can drip into the soil near the roots of the strawberry plants through the elastic spiral tube 2 6, the loop tube 2, the connecting tube 3, the elastic spiral tube 31 and the insertion tube 4 and the water outlet 45. The water droplets slowly discharged from the water outlet 45 will moisten the soil and provide water to the roots of the strawberry plants. The water droplets discharged through the water outlet 45 will not cause impact on the soil, thus ensuring that the soil near the roots of the strawberry plants will not form waterlogged pits or increase soil hardness, avoiding the problem of affecting the germination of new roots and the lateral expansion of the root system, and limiting the absorption of deep nutrients and water by the strawberry plants.

[0049] Example 2:

[0050] This embodiment provides a drip irrigation device for strawberry cultivation. In addition to the technical solutions of the above embodiments, it also has the following technical features, including a control component:

[0051] Four limiting grooves 12 are respectively opened on four support tubes 1, and the limiting grooves 12 are connected to the through grooves 11. A limiting rod 24 is slidably installed in the limiting groove 12. One end of the limiting rod 24 is fixedly connected to a rotating column 23 connected to the loop tube 2 inside the support tube 1.

[0052] When personnel need to replace the entire strawberry plant with a new variety, the U-shaped tube 2 can be lifted and moved up the four through slots 11 until the U-shaped tube 2 contacts the top of the through slot 11. Then, the personnel hold the limiting rod 24 and rotate it, causing the rotating column 23 to rotate on the U-shaped tube 2. The limiting rod 24 is rotated into the limiting slot 12, ensuring that the U-shaped tube 2 is stably fixed between the four support tubes 1. The elastic spiral tube 2 6 has elasticity and automatically contracts to form a spiral shape, making it easy for the elastic spiral tube 2 6 to be stored in the support tube 1. At the same time, when the insertion tube 4 is removed from the soil, when the insertion tube 4 is pulled down without tension, the elastic spiral tube 31 will also have elasticity and automatically contract to form a spiral shape, making it easy for personnel to clean the strawberry plants on the soil below the insertion tubes 4.

[0053] Example 3:

[0054] This embodiment provides a strawberry drip irrigation device. In addition to the technical solutions of the above embodiments, it also has the following technical features: the limiting rod 24 and the rotating column 23 are integrally formed, the rotating column 23 is rotatably connected to the U-shaped tube 2, and the limiting rod 24 is slidably connected to the through groove 11.

[0055] In this way, the structure of the limiting rod 24 and the rotating column 23 is kept stable, the rotating column 23 can rotate normally on the loop tube 2, and the limiting rod 24 can move up and down normally in the through groove 11.

[0056] Example 4:

[0057] This embodiment provides a strawberry drip irrigation device. In addition to the technical solutions of the above embodiments, it also has the following technical features: a rotating groove 41 is provided inside the insertion tube 4, a ball 42 is rotatably installed inside the rotating groove 41, a through hole 43 is provided inside the ball 42, a handle 44 is rotatably installed inside the insertion tube 4, and one end of the handle 44 passes through one side of the insertion tube 4 and is fixed to the ball 42. The diameter of the water outlet 45 is 0.1-0.2cm.

[0058] The rotating handle 44 can drive the ball 42 in the rotating groove 41 to rotate, so that the through hole 43 faces the inner wall of the rotating groove 41, thereby ensuring that the water in the insertion tube 4 can be disconnected. When the strawberry plant roots are short of water, the personnel can rotate the ball 42 by rotating the handle 44 to connect the insertion tube 4 with the through hole 43, ensuring that the liquid in the elastic spiral tube 31 can be discharged through the insertion tube 4 and several water outlet holes 45 without causing impact on the soil.

[0059] Example 5:

[0060] This embodiment provides a strawberry drip irrigation device. In addition to the technical solutions of the above embodiments, it also has the following technical features: the through hole 43 is connected to the insertion tube 4, the diameter of the through hole 43 is smaller than the thickness of the rotating groove 41, and the handle 44 and the ball 42 are integrally formed.

[0061] Specifically, this ensures that water in the insertion tube 4 can flow through the through hole 43. When the through hole 43 faces the inner wall of the rotating groove 41, the through hole 43 will be sealed by the inner wall of the rotating groove 41, preventing the insertion tube 4 from draining water and ensuring the structural stability of the handle 44 and the ball 42.

[0062] Example 6:

[0063] This embodiment provides a strawberry drip irrigation device. In addition to the technical solutions of the above embodiments, it also has the following technical features: the bottom ends of the four support pipes 1 are all fixedly installed with a base plate 13, the tops of the four mixing tanks 5 are all fixedly installed with a motor 51, and the output shaft of the motor 51 passes through the top of the mixing tank 5 and is fixedly installed with a number of mixing rods 52.

[0064] The four base plates 13 are conveniently buried deep in the soil to ensure the structural stability of the four support pipes 1. The motor 51 and several stirring rods 52 ensure that personnel can put water and fertilizer into the mixing tank 5 together, or put pesticides or water into the mixing tank 5 together. The output shaft of the motor 51 drives several stirring rods 52 to stir and mix evenly, which can make the strawberry plants grow healthily or eliminate pests in the soil.

[0065] Example 7:

[0066] This embodiment provides a strawberry drip irrigation device. In addition to the technical solutions of the above embodiments, it also has the following technical features: the output shaft of the motor 51 is rotatably connected to the stirring drum 5, and the distance between the base 13 and the through groove 11 is 30-100cm.

[0067] Among these measures, it is essential to ensure that the motor 51 can operate normally on the mixing tank 5, that the chassis 13 can be buried deeper into the soil, and that the overall structure of the device is stable.

[0068] Example 8:

[0069] This embodiment provides a strawberry drip irrigation device. In addition to the technical solution of the above embodiment, it also has the following technical features: the U-shaped tube 2 and several connecting tubes 3 are integrally formed, and the U-shaped tube 2 is connected to the connecting tubes 3 and the elastic spiral tube 31. The stirring drum 5 is connected to the elastic spiral tube 6 and the U-shaped tube 2.

[0070] In this process, the structure of the spiral tube 2 and several connecting tubes 3 is kept stable, ensuring that the liquid in the stirring drum 5 can enter the insertion tube 4 through the elastic spiral tube 2 6, the spiral tube 2, the connecting tube 3 and the elastic spiral tube 31.

[0071] It is worth noting that the entire device is located inside a greenhouse, and the four base plates 13 must first be buried in the soil to ensure the structural stability of the entire device.

[0072] It is worth noting that when there is no downward pulling force, the elastic spiral tube 31 and the elastic spiral tube 6 can automatically contract upward.

[0073] Working principle: Personnel put fertilizer and water into the mixing tank 5 together. Then, the motor 51 is connected to the power supply and started. The output shaft of the motor 51 drives several mixing rods 52 to mix the fertilizer and water evenly. Then, the personnel hold the limiting rod 24 and rotate it, which drives the rotating column 23 to rotate on the loop tube 2. The limiting rod 24 is rotated into the through groove 11, so that the loop tube 2 slides down between the four through grooves 11. The loop tube 2 also drives the elastic spiral tube 6 to be stretched until the limiting rod 24 touches the bottom of the through groove 11.

[0074] The operator pulls down the insertion tube 4 to extend the elastic spiral tube 31 downwards. Then, the two rotating blades 46 are rotated and opened on both sides of the insertion tube 4. The bottom end of the insertion tube 4 is then placed near the roots of the strawberry plant in the soil. Then, soil is covered on the bottom end of the insertion tube 4 and the two rotating blades 46 to ensure the stability of the insertion tube 4. Then, the operator turns the handle 44 to rotate the ball 42 in the rotating groove 41, so that the insertion tube 4 is connected to the through hole 43.

[0075] Under the influence of gravity, the water in the mixing drum 5 passes through the elastic spiral tube 2 6, the loop tube 2, the connecting tube 3, the elastic spiral tube 31, and the insertion tube 4, and drips into the soil near the roots of the strawberry plants through the water outlet 45. The water droplets slowly discharged from the water outlet 45 moisten the soil and provide water and nutrients to the roots of the strawberry plants. This ensures that the water droplets discharged through the water outlet 45 do not cause impact on the soil, thereby ensuring that the soil near the roots of the strawberry plants does not form waterlogged pits or increase soil hardness. This avoids affecting the germination of new roots and the lateral expansion of the root system, and prevents the strawberry plants from absorbing deep nutrients and water.

[0076] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
