Description

Technical Field

[0001] This utility model belongs to the field of wheat cultivation technology, and specifically relates to a drip irrigation device for cultivating cold-resistant wheat. Background Technology

[0002] In the breeding trials of cold-resistant wheat varieties, it is necessary not only to precisely control the water supply, but also to maintain a stable low-temperature resistance in the breeding environment. During the low-temperature breeding stage, cold-resistant wheat seedlings need to avoid drought and water shortage that would reduce their cold resistance, and also to prevent the water temperature from being too low in traditional irrigation methods that would stimulate the root system, or the soil temperature from dropping sharply after irrigation that would affect the seedling growth. In the existing technology, the staff uses drip irrigation to water the wheat seedlings.

[0003] For example, Chinese patent CN220755982U discloses a circulating drip irrigation device for wheat cultivation, which includes a water storage tank. A cultivation shell is fixedly connected to the top of the water storage tank, and the same seepage plate and support frame are fixedly connected to the opposite inner walls of the cultivation shell.

[0004] The aforementioned patent describes a method that uses a pump to deliver water into the drip irrigation housing, allowing the housing to irrigate wheat seedlings through the drip irrigation pipes. However, this drip irrigation device has some drawbacks that require improvement. Specifically, water stains tend to remain inside the drip irrigation pipes after each irrigation session. Since cold-resistant wheat is often grown in low-temperature environments, these residual water stains can easily freeze inside the pipes. Even with an insulation sleeve on the outside of the pipes, it is difficult to completely prevent localized freezing inside the pipes. Long-term use can lead to deformation of the drip irrigation pipes and even blockage of the drip irrigation holes, affecting the uniformity and smoothness of subsequent irrigation. Furthermore, it may promote the growth of microorganisms, contaminating the water source for the next irrigation session and potentially impacting the growth of sensitive cold-resistant wheat seedlings.

The moisture-absorbing column can quickly absorb residual water stains in the pipe, avoiding the situation where water stains freeze into ice in low-temperature environments from the source, preventing the deformation of the drip irrigation pipe and the blockage of the drip irrigation holes caused by freezing, ensuring the uniformity and smoothness of subsequent drip irrigation, and also reducing the risk of microbial growth caused by long-term water stain residue, ensuring the cleanliness of the water source for the next drip irrigation.

[0014] Secondly, by setting up a connecting component, this utility model allows multiple moisture-absorbing columns to be removed simultaneously, facilitating the replacement of multiple moisture-absorbing columns at the same time. This significantly shortens the replacement time for multiple moisture-absorbing columns, avoids the inefficiency caused by operating them one by one, and ensures that all moisture-absorbing columns are installed at a uniform precision after replacement.

A second repositioning component 10 is provided on one side of the first repositioning component 8. A connecting component 11 is provided on one side of the second repositioning component 10. A moisture-absorbing column 9 is provided on one side of the connecting component 11. The moisture-absorbing column 9 is composed of a super absorbent resin sponge sleeve and a metal column. The super absorbent resin sponge sleeve is fixed on the outside of the metal column. The moisture-absorbing column 9 is movably connected to the inside of the drip irrigation pipe 4. The water storage tank 1 is also provided with an electric heating component, a temperature sensor, etc., for controlling the drip irrigation water temperature.

[0022] refer to Figure 1 The power assembly 5 includes a first motor 51, which is fixedly connected to one side of the water storage tank 1. Both sides of the water storage tank 1 are rotatably connected to first lead screws 52. The output end of the first motor 51 is fixedly connected to one end of one of the first lead screws 52. A sprocket 53 is fixedly connected to one side of the first lead screw 52. The two sprockets 53 are connected by a chain 54. Both sides of the mounting frame 3 are threadedly connected to the first lead screw 52. By setting up the power assembly 5, when the position of the drip irrigation pipe 4 needs to be adjusted, the first motor 51 drives the directly connected first lead screw 52 to rotate. The first lead screw 52 drives the sprocket 53 to rotate synchronously. Then, the chain 54 drives the sprocket 53 on the other side and the corresponding first lead screw 52 to rotate synchronously, thereby moving the drip irrigation pipe 4 at the bottom, facilitating drip irrigation operations.

[0023] refer to Figure 1The first repositioning component 8 includes an electric push rod 81, which is fixedly connected to both sides of one end of the assembly frame 3. The output ends of the two electric push rods 81 are fixedly connected to a movable frame 82. The second repositioning component 10 is mounted on the movable frame 82. Guide rods 83 are fixedly connected to both sides of the top of the movable frame 82, and guide sleeves 84 are fixedly connected to both sides of the top of the assembly frame 3. One side of the guide rod 83 slides through the guide sleeve 84. By setting the first repositioning component 8, when water stains need to be cleaned after drip irrigation, the electric push rods 81 on both sides of one end of the assembly frame 3 are activated. The output ends of the electric push rods 81 extend, pushing the movable frame 82 fixed to them to move closer to the drip irrigation pipe 4. During the movement of the movable frame 82, the guide rods 83 on both sides of its top slide along the guide sleeves 84 at the top of the assembly frame 3 to guide the movable frame 82. When the movable frame 82 moves to the designated position, the electric push rods 81 are turned off. This design can adjust the position of the moisture-absorbing column 9 to avoid it always being below the drip irrigation pipe 4 and affecting its use.

[0024] refer to Figure 1 and Figure 4 The second repositioning component 10 includes a second motor 101, which is fixedly connected to the top of the movable frame 82. A drive gear 102 is fixedly connected to the output end of the second motor 101. A driven gear 103 is meshed with one side of the drive gear 102. A second lead screw 104 is fixedly connected to one side of the driven gear 103. The second lead screw 104 is rotatably connected to the lower inner side of the movable frame 82. A screw block 105 is threaded onto the outer surface of the second lead screw 104. One side of the screw block 105 is fixedly connected to one side of the connecting component 11. Guide grooves 106 are provided on both sides of the second lead screw 104 within the movable frame 82. Guide blocks 107 are slidably connected inside the guide grooves 106. One side is fixedly connected to the side of the screw block 105; by setting the second repositioning component 10, the second motor 101 drives the driving gear 102 to rotate, the driving gear 102 drives the driven gear 103 to rotate, thereby causing the second lead screw 104 on one side of the driven gear 103 to rotate inside the lower side of the moving frame 82. When the second lead screw 104 rotates, the screw block 105 threaded to its outer surface moves along the lead screw axis. At the same time, the guide block 107 on one side of the screw block 105 slides along the guide groove 106 in the moving frame 82. The movement of the screw block 105 drives the fixed connecting component 11 and the moisture-absorbing column 9 to move until the moisture-absorbing column 9 extends into the drip irrigation pipe 4, which can absorb the water stains remaining inside the drip irrigation pipe 4. After cleaning, the second motor 101 is started in reverse, which can drive the moisture-absorbing column 9 to detach from the drip irrigation pipe 4.

[0025] refer to Figure 3The connecting assembly 11 includes a first connecting plate 111, which is fixedly connected to one side of the screw block 105. A slot 113 is provided inside the first connecting plate 111, and a plug 114 is inserted into the slot 113. A second connecting plate 112 is fixedly connected to the top of the plug 114, and the top of the second connecting plate 112 is fixedly connected to the bottom of the moisture-absorbing column 9. The plug 114 is fixedly connected to the slot 113 by a fixing bolt 115. By setting the connecting assembly 11, when installing the moisture-absorbing column 9... Align the insert 114 at the bottom of the second connecting plate 112 with the slot 113 inside the first connecting plate 111, insert the insert 114 into the slot 113, and then pass the fixing bolt 115 through the corresponding screw holes of the first connecting plate 111 and the insert 114, and tighten the fixing bolt 115 to complete the fixing of the moisture-absorbing column 9 and the connecting assembly 11. When the moisture-absorbing column 9 has reduced adsorption capacity and needs to be replaced, unscrew the fixing bolt 115, pull the insert 114 out of the slot 113, and the old moisture-absorbing column 9 can be removed. After replacing the new moisture-absorbing column 9, repeat the above installation steps.

[0026] Operating principle and advantages: The first motor 51 drives the first lead screw 52 to rotate. The first lead screw 52 is driven by the sprocket 53 and the chain 54, causing the first lead screws 52 on both sides to rotate synchronously. This causes the threaded assembly frame 3 to slide along the lead screw, thereby causing the drip irrigation pipe 4 at the bottom to slide above the seepage plate 2. The water pump 6 is started, and the water pump 6 delivers the warm water in the water storage tank 1 to the water pipe 7, and then the water pipe 7 distributes it to the drip irrigation pipe 4. The drip irrigation pipe 4 drip irrigates the cold-resistant wheat seedlings. When cleaning up water stains after drip irrigation, the electric push rod 81 drives the moving frame 82 to move closer to the drip irrigation pipe 4. The guide rod 83 at the top of the moving frame 82 slides along the guide sleeve 84 to ensure that the moving frame 82 is stable and does not deviate. After the moving frame 82 is in place, the second repositioning component 10 is started, and the second motor 101 drives... The driving gear 102 rotates, and through meshing transmission, the driven gear 103 drives the second lead screw 104 to rotate. The threaded block 105 moves along the lead screw, causing the moisture-absorbing column 9 to extend into the drip irrigation pipe 4. The super absorbent resin sponge sleeve on the outside of the moisture-absorbing column 9 can quickly absorb residual water stains in the pipe, preventing water stains from freezing in low-temperature environments, which could cause deformation or blockage of the drip irrigation pipe 4. When the absorption capacity of the moisture-absorbing column 9 decreases, maintenance and replacement are required. Unscrew the fixing bolt 115 between the first connecting plate 111 and the insert 114 in the connecting assembly 11, and pull the insert 114 out of the slot 113 to remove the old moisture-absorbing column 9. After replacing the new moisture-absorbing column 9, reinsert the insert 114 and tighten the bolt. The operation is simple and convenient, requires no complicated tools, and can quickly restore the water stain cleaning ability, making it suitable for the continuous operation needs of cold-resistant wheat cultivation.
