[0032] The water pressure component includes a sliding ring frame 51, and the sliding ring frame 51 is connected to the top of the water tank 1 by bolts. A water pressure rod 52 is slidably connected to the sliding ring frame 51. The water pressure rod 52 is used to push water for drip irrigation. The lower part of the water pressure rod 52 is located in the water tank 1. A counterweight block 53 is welded to the top of the water pressure rod 52. A rubber ring 54 is fixedly connected to the lower part of the water pressure rod 52. The rubber ring 54 is made of rubber. The rubber ring 54 is used to enhance the sealing between the water pressure rod 52 and the inner wall of the water tank 1. The rubber ring 54 contacts the inner wall of the water tank 1.
[0033] The water outlet control component includes a bracket 61, the bracket 61 is connected to the upper part of the outer wall of the water tank 1 by bolts, a piston cylinder 62 is connected to the bracket 61 by bolts, a piston rod 63 is slidably connected to the piston cylinder 62, the piston rod 63 passes through the water tank 1, an extrusion slope is provided on the piston rod 63, a pressure spring 64 is connected between the piston rod 63 and the piston cylinder 62 by a hook, the pressure spring 64 is located in the piston cylinder 62, a sliding mounting rod 65 is welded to the upper part of the inner wall of the water tank 1, a push rod 651 is slidably connected to the sliding mounting rod 65, an extrusion head 66 is slidably connected to the push rod 651, an end of the extrusion head 66 away from the piston rod 63 is in contact with the water pressure rod 52, a reset spring 67 is connected between the extrusion head 66 and the push rod 651 by a hook, and the reset spring 67 is located in the push rod 651.
[0034] Initially, the piston cylinder 62 is filled with a proper amount of hydraulic oil, the piston rod 63 squeezes the push rod 651, and the return spring 67 is in a compressed state. First, the operator pulls the water pressure rod 52 to move upward, then opens the water inlet pipe 41, and passes water into the water tank 1 through the water inlet pipe 41. When the water tank 1 is full of water, the operator releases the water pressure rod 52 and closes the water inlet pipe 41. Then the counterweight 53 drives the water pressure rod 52 to move downward under the action of gravity. The downward movement of the water pressure rod 52 drives the rubber ring 54 to move downward, and the water pressure rod 52 pushes the water in the water tank 1 through the connecting ball tube 2 and the connecting hose 3. The water in the branch pipe 4 will then drip onto the vegetables through the drip irrigation ports on the branch pipe 4. When the temperature rises, the hydraulic oil in the piston cylinder 62 will expand due to the heat, and the hydraulic oil in the piston cylinder 62 will push the piston rod 63 to move horizontally. The pressure spring 64 will be compressed, and the piston rod 63 will no longer squeeze the push rod 651, and the return spring 67 will rebound. The rebound of the return spring 67 will drive the push rod 651 to move away from the water pressure rod 52, and the friction between the extrusion head 66 and the water pressure rod 52 will decrease, so that the speed at which the counterweight block 53 drives the water pressure rod 52 to move downward increases with the temperature. When the temperature rises, the hydraulic oil in the piston cylinder 62 will cool and shrink, and the pressure spring 1 64 will reset. The reset of the pressure spring 1 64 will drive the piston rod 63 to move horizontally in the opposite direction and reset. The reset of the piston rod 63 will squeeze the push rod 651 to move toward the direction close to the water pressure rod 52 and reset. The reset spring 67 will be compressed again, and the friction between the extrusion head 66 and the water pressure rod 52 will increase, so that the speed at which the counterweight block 53 drives the water pressure rod 52 to move downward will slow down as the temperature drops. When the water in the water tank 1 is used up, the operator will pull the water pressure rod 52 to reset upward, and the water pressure rod 52 will be pushed back to the original position. The reset of the water rod 52 will drive the rubber ring 54 and the counterweight 53 to move upward and reset. Then the operator will open the water inlet pipe 41 and pass water into the water tank 1 through the water inlet pipe 41. When the water tank 1 is full of water, the operator will loosen the water pressure rod 52 and close the water inlet pipe 41 again. In this way, the friction between the extrusion head 66 and the water pressure rod 52 can be increased or decreased through the thermal expansion and contraction of the hydraulic oil, so that the drip irrigation speed of water can be accelerated or slowed down with the rise and fall of temperature, and then the vegetables can be drip irrigated according to the water demand of vegetables at different temperatures, so that the drip irrigation effect of vegetables is better.
[0035] Embodiment 2: Based on embodiment 1, Figure 1-Figure 7As shown, it also includes a water stop component, which is arranged on the connecting ball tube 2. The water stop component includes a one-way ball valve 71. The one-way ball valve 71 is rotatably connected in the connecting ball tube 2. A column gear 72 is rotatably connected to the lower bottom of the water tank 1. The column gear 72 passes through the connecting ball tube 2. The column gear 72 is fixedly connected to the one-way ball valve 71. A sliding frame 721 is welded to the lower part of the outer wall of the water tank 1. A gear rod 73 is welded to the piston rod 63. The sliding frame 721 is used to guide the gear rod 73. The gear rod 73 will mesh with the column gear 72. The gear rod 73 is slidably connected to the sliding frame 721.
[0036] As the temperature drops, the piston rod 63 will move horizontally in the opposite direction under the action of the pressure spring 64. The reverse horizontal movement of the piston rod 63 will drive the gear rod 73 to move horizontally in the opposite direction and reset. The gear rod 73 will mesh with the column gear 72. The reverse horizontal movement of the gear rod 73 will drive the column gear 72 to rotate. The rotation of the column gear 72 will drive the one-way ball valve 71 to rotate, so that the one-way ball valve 71 gradually blocks the connecting ball pipe 2. When the temperature is below 0°C, the one-way ball valve 71 will completely block the connecting ball pipe 2. As the temperature rises, the hydraulic oil in the piston cylinder 62 will push the piston rod When the gear 73 moves horizontally, the piston rod 63 will drive the gear rod 73 to move horizontally. The horizontal movement of the gear rod 73 will drive the column gear 72 to rotate in the opposite direction. The opposite rotation of the column gear 72 will drive the one-way ball valve 71 to rotate in the opposite direction. The one-way ball valve 71 will no longer block the connecting ball tube 2. Then the gear rod 73 will disengage from the column gear 72. In this way, the one-way ball valve 71 can be driven to rotate by the column gear 72, so that the connecting ball tube 2 can be blocked when the temperature is below 0°C, thereby stopping drip irrigation when the temperature is below 0°C to prevent water from freezing and frostbiting the vegetables, thereby protecting the vegetables.
[0037] Embodiment 3: Based on embodiment 2, Figure 8-Figure 11 As shown, it also includes an anti-clogging component, which is arranged on the water tank 1. The anti-clogging component includes a rotating mounting plate 81, and the rotating mounting plate 81 is welded to the lower part of the inner wall of the water tank 1. A screw 82 is rotatably connected to the rotating mounting plate 81, and the screw 82 passes through the water pressure rod 52. The bottom end of the screw 82 is connected to a scraper 83 by bolts. The scraper 83 is used to scrape off the scale at the bottom of the inner wall of the water tank 1. The bottom of the scraper 83 contacts the bottom of the inner wall of the water tank 1. A nut 84 is connected to the water pressure rod 52 by bolts, and the nut 84 is threadedly connected to the screw 82.
[0038] When the counterweight block 53 drives the water pressure rod 52 to move downward, the water pressure rod 52 will drive the nut 84 to move downward, and the downward movement of the nut 84 will drive the screw 82 to rotate through the thread, and the rotation of the screw 82 will drive the scraper 83 to rotate, and the scraper 83 will scrape off the scale at the bottom of the water tank 1. When the operator pulls the water pressure rod 52 to move upward and reset, the water pressure rod 52 will drive the nut 84 to move upward, and the upward movement of the nut 84 will drive the screw 82 to rotate in the opposite direction through the thread, and the reverse rotation of the screw 82 will drive the scraper 83 to rotate in the opposite direction. In this way, the scale deposited on the bottom of the inner wall of the water tank 1 can be cleaned, thereby reducing the occurrence of scale accumulation and clogging of the connecting tube 2.
[0039] Embodiment 4: Based on the embodiment 3, Figure 5-Figure 12 As shown, it also includes a sliding mounting block 91, the sliding mounting block 91 is welded on the top of the sliding ring frame 51, and a clamping rod 92 is slidably connected to the sliding mounting block 91. A plurality of locking holes 93 are opened on the water pressurizing rod 52, and one end of the clamping rod 92 is located in one of the locking holes 93. The clamping rod 92 is used to limit the water pressurizing rod 52.
[0040] At first, one end of the clamping rod 92 is located in one of the locking holes 93 on the water pressure rod 52, and the clamping rod 92 limits the water pressure rod 52. When drip irrigation of vegetables is needed, the operator will pull the clamping rod 92 to move away from the water pressure rod 52, and the clamping rod 92 will be out of contact with one of the locking holes 93 on the water pressure rod 52, and the clamping rod 92 will no longer limit the water pressure rod 52. Then the counterweight block 53 will drive the water pressure rod 52 to move downward. When the rainy season comes, the operator will push the clamping rod 92 to move toward the direction close to the water pressure rod 52 and reset it. One end of the clamping rod 92 will be stuck in another locking hole 93 on the water pressure rod 52, and the clamping rod 92 will limit the water pressure rod 52 again. In this way, it is convenient to stop drip irrigation of vegetables when the rainy season comes, thereby preventing the situation where the amount of water in the vegetables is too sufficient to submerge the soil.
[0041] Embodiment 5: Based on Embodiment 4, Fig.13 As shown, a support rod 10 is also included, and a plurality of support rods 10 are connected to the lower part of the branch pipe 4 by rivets.
