DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] Embodiment 1
[0025] As attached Figures 1 to 5 A breathable drainage device is shown, comprising an outer tube 1, an inner tube 3 is wrapped inside the outer tube 1, a threaded flange 4 is fixedly connected to the top of the inner tube 3, one end of the threaded flange 4 is fixedly connected to a support frame 7, a pressure rod 6 is rotatably connected inside the support frame 7, one end of the pressure rod 6 close to the center of the threaded flange 4 is rotatably connected to a connecting rod 5, a mounting block 10 is welded to the bottom end of the connecting rod 5, a fixing ring 9 is fixedly connected inside the inner tube 3, a groove is provided inside the fixing ring 9, the inner diameter of the groove matches the outer diameter of the mounting block 10, a pull block 17 is installed at one end of the support frame 7, a connecting block 18 is glued to one end of the pull block 17, and a limiting block 19 is glued to one end of the connecting block 18;
[0026] A cross bar 12 runs through the other end of the support frame 7 , a fixing bolt 15 is threadedly connected to the outer side of one end of the cross bar 12 , a waterproof shell 14 is installed on the outer side of the fixing bolt 15 , and protrusions 13 are fixedly connected to both ends of the waterproof shell 14 .
[0027] Wherein: in the process of fertilizing crops, the bottom end of the inner tube 3 is blocked by controlling the position of the mounting block 10, so that the fertilizer enters the soil through the air holes installed on the outside of the outer tube 1, fertilizes the roots of the crops, reduces the waste of fertilizer, and makes the crops absorb more fully. The cross bar 12 needs to be fixed by the fixing bolts 15. The fixing bolts 15 are easy to contact with water after being used for too long, so that they rust and corrode, reducing their service life. By installing a waterproof shell 14 on the outside of the bolt, the waterproof shell 14 is made of plastic. The waterproof shell 14 protects the cross bar 12 and the bolt, isolates them from the outside, reduces their corrosion, and increases their service life.
[0028] Embodiment 2
[0029] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working methods. Figures 1 to 5 As shown, see the following description for details:
[0030] As a preferred embodiment, air holes are opened on the outside of the outer tube 1, and a number of drainage holes are opened, so that air can enter the soil through the air holes, increase the oxygen content in the soil, and increase the vitality of the crop root system.
[0031] As a preferred embodiment, the bottom end of the outer tube 1 is fixedly connected to a drain pipe 2, and the top of the drain pipe 2 is connected to the inner tube 3. When there is too much rainwater and irrigation water inside the farmland, the excess water can be quickly discharged through the drain pipe 2.
[0032] As a preferred embodiment, a nylon mesh 11 is fixedly connected to the outer side of the inner tube 3. The nylon mesh 11 is attached between the outer tube 1 and the inner tube 3, which can effectively prevent soil from entering the inner tube 3. The material of the nylon mesh 11 is nylon, ensuring the ventilation efficiency of the air holes.
[0033] As a preferred embodiment, the mounting block 10 is made of rubber products, and there is a gap between the outer side of the mounting block 10 and the inner tube 3. The rubber material makes the mounting block 10 waterproof, increases the service life of the mounting block 10, and allows excess fertilizer and water to flow out through the drain pipe 2 after the mounting block 10 and the fixing ring 9 are separated.
[0034] As a preferred embodiment, a fluorescent lamp 8 is fixedly connected to one end of the threaded flange 4, and the fluorescent lamp 8 is installed on one side above the outer tube 1. By installing the fluorescent lamp 8 above the outer tube 1, the staff can find the position of the outer tube 1 at night to prevent tripping.
[0035] As a preferred embodiment, a card slot is opened at one end of the support frame 7, and the size of the card slot matches the protrusion 13. The position of the waterproof shell 14 is fixed by the card connection of the protrusion 13 to prevent the waterproof shell 14 from falling off.
[0036] As a preferred embodiment, one end of the cross bar 12 is in contact with the limit block 19, and a telescopic spring 16 is installed at one end of the limit block 19 close to the connecting block 18. The limit block 19 and the cross bar 12 are separated by pulling the pull block 17, so that the pressure rod 6 can rotate. When the pressure rod 6 needs to be limited, the elastic force of the telescopic spring 16 drives the limit block 19 to limit the position of the cross bar 12, so that the pressure rod 6 stops rotating.
[0037] The working principle of the utility model is as follows:
[0038] First, by pulling the pull block 17, the limit block 19 is driven to move to one side, and then the position of the pressure rod 6 is lifted to make the position of the fixing ring 9 and the mounting block 10 fit together, and then the pull block 17 is released, and the elastic force of the telescopic spring 16 drives the limit block 19 and the cross bar 12 to engage, and the position of the cross bar 12 is fixed. The cross bar 12 controls the position of the pressure rod 6 to make the fixing ring 9 and the mounting block 10 fit together, and the gap between the inner tube 3 and the drainage pipe 2 is blocked, and then fertilizer is injected into the inner tube 3. The fertilizer enters the soil through the air holes on the surface of the outer tube 1 and directly reaches the root system of the crops, thereby reducing the waste of fertilizer and making the crops absorb it more completely. When too much rainwater accumulates in the farmland, the pressure rod 6 is pressed to drive the connecting rod 5 to move upward, so that the fixing ring 9 and the mounting block 10 are separated, so that the excessive rainwater can enter the drainage pipe 2 and drain the rainwater;
[0039] Afterwards, a waterproof shell 14 is installed at one end of the support frame 7, and the waterproof shell 14 is pressed to deform, so that the protrusions 13 fixedly connected at both ends of the waterproof shell 14 can be snapped into the slots opened inside the pressure rod 6, thereby protecting the fixing bolts 15, reducing the contact between rainwater and the fixing bolts 15, slowing down the corrosion rate of the fixing bolts 15, and increasing the service life of the fixing bolts 15.
[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
