Description

Technical Field

[0001] The invention relates to the technical field of garden machinery, in particular to a water-saving garden greening irrigation device and an irrigation method. Background Art

[0002] Technical measures to supplement the water needed by crops in landscape greening. In order to ensure the normal growth of plants, plants must be supplied with sufficient water. Under natural conditions, the water requirements of plants are often not met due to insufficient precipitation or uneven distribution. Therefore, artificial irrigation must be carried out to make up for the lack of natural rainfall.

[0003] For example, a garden greening water-saving irrigation device with publication number CN112021152A drives a piston plate to move in a water storage barrel through a reciprocating drive mechanism, thereby achieving water pumping, pressurization and spraying, and a rotating spray head can spray water evenly. During the rotation of the spray head, the position of the counterweight block changes under the action of centrifugal force, and then the inclination angle of the elastic hose changes, so that the water can be sprayed evenly on the greening. However, in actual use, the garden greening is irrigated by rotating the spray head. After the spray head sprays water, the spraying distance will become farther under the action of centrifugal force, which can expand the irrigation range to a certain extent. However, the sprayed water will move away from the bottom plate under the action of centrifugal force, and the area near the bottom plate cannot be well irrigated, and irrigation needs to be repeated later, which cannot guarantee the uniformity of irrigation and cannot achieve a good water-saving effect. There are certain defects in use.

[0004] Therefore, we propose a water-saving gardening irrigation device and irrigation method to solve the above-mentioned problems. Summary of the invention

[0026] Embodiment 1: Figure 1-Figure 9As shown, an irrigation assembly 2 is arranged on the top of the water tank 101. When irrigating the garden, water is added to the inside of the water tank 101 through the water inlet 102, and the water pump 103 is started to pump water from the water tank 101, so that the water in the water tank 101 enters the hollow disk 201 through the hollow pipe 104 and the connecting pipe 202, and then is sprayed out through the nozzle on the water outlet pipe 203. The driving motor 204 is started to drive the rotating shaft 206 to rotate, and the rotating shaft 206 drives the driving gear 208 to rotate after the rotating shaft 206 rotates.

[0028] Embodiment 2: Figure 4-Figure 7 and Fig. 9As shown, while the hollow disk 201 rotates and drives the nozzles on the water outlet pipe 203 to reciprocate in the horizontal plane, the movement of the sliding rod 215 can drive the fixed sleeve 219 to move, and the fixed sleeve 219 moves close to the support frame 214. While the fixed sleeve 219 moves, the connecting rod 224 between the mounting frames 223 will rotate. The rotation of the connecting rod 224 can push the sliding block 222 to slide inside the fixed sleeve 219, and the movement of the sliding block 222 drives the moving rod 220 to slide on the fixed sleeve 219, thereby pulling the nozzles on the water outlet pipe 203 to move up and down. The two groups of nozzles on the water outlet pipes 203 can be irrigated in an umbrella shape under the rotation of the hollow disk 201.

[0030] Embodiment 3: Figure 4-Figure 7 and Fig. 9 As shown, the two moving rods 220 can pull the two rotating gears 230 to descend while they are descending. The two rotating gears 230 can rotate by meshing with the rack 229 on the support rod 228 while they are descending, thereby driving the rotating rod 225 to rotate. After the rotating rod 225 rotates, it drives the mounting block 226 to rotate, and then the nozzles on the water outlet pipe 203 can be driven to rotate downward through the mounting ring 227, so that the two groups of nozzles can rotate downward while moving and descending, and the area near the base 1 can be fully irrigated through the nozzles, so that the nozzles on the water outlet pipe 203 can reciprocate up and down while reciprocating in the horizontal plane, and can reciprocate, thereby fully expanding the irrigation range of the nozzles, ensuring the uniformity of irrigation, avoiding repeated irrigation, improving the uniformity of irrigation, and achieving a water-saving effect.

[0031] Working principle: When using this water-saving garden irrigation device, first, according to Figure 1-Figure 9As shown, when irrigating the garden, water is added to the water tank 101 through the water inlet 102, and the water pump 103 is started to pump water from the water tank 101, so that the water in the water tank 101 enters the hollow disk 201 through the hollow tube 104 and the connecting tube 202, and then is sprayed out through the nozzle on the water outlet pipe 203. The driving motor 204 is started to drive the rotating shaft 206 to rotate, and the rotating shaft 206 rotates and then drives the driving gear 208 to rotate. The driving gear 208 can drive the hollow disk 201 to rotate by meshing with the inner gear ring 205, so that the spraying range of the water outlet pipe 203 can be more uniform. While the hollow disk 201 rotates, the two sets of spherical parts 212 slide inside the limiting ring 211 , so that the rotation of the hollow disk 201 can be supported. When the hollow disk 201 rotates, it drives the two sets of sliding rods 215 to rotate in a circle. When the sliding rod 215 rotates, the ball 217 can roll on the inner protrusion 216 of the fixing ring 210, and then the sliding rod 215 can be pushed by the ball 217 to slide on the support frame 214, and the telescopic spring 218 can be stretched, so that the nozzle on the water outlet pipe 203 can be pulled to move. After the ball 217 leaves the protrusion 216, the telescopic spring 218 drives the sliding rod 215 to reset, so that the irrigation range can reciprocate on the horizontal plane. When the hollow disk 201 rotates and drives the nozzle on the water outlet pipe 203 to reciprocate on the horizontal plane, the sliding rod 215 can be pushed by the ball 217 to slide on the support frame 214, and the telescopic spring 218 can be stretched, so that the nozzle on the water outlet pipe 203 can be pulled to move. The movement of the movable rod 215 can drive the fixed sleeve 219 to move, and the fixed sleeve 219 moves close to the support frame 214. When the fixed sleeve 219 moves, the connecting rod 224 between the mounting frames 223 will rotate. The rotation of the connecting rod 224 can push the sliding block 222 to slide inside the fixed sleeve 219, and the movement of the sliding block 222 drives the movable rod 220 to slide on the fixed sleeve 219, thereby pulling the nozzles on the water outlet pipe 203 to move up and down. The two groups of nozzles on the water outlet pipes 203 can be irrigated in an umbrella shape under the rotation of the hollow disk 201. The nozzles on the water outlet pipes 203 can be lowered while approaching the hollow disk 201, and the two movable rods 220 can be pulled while descending. The two rotating gears 230 are driven to descend, and the two rotating gears 230 can rotate by meshing with the rack 229 on the support rod 228 while descending, thereby driving the rotating rod 225 to rotate. After the rotating rod 225 rotates, it drives the mounting block 226 to rotate, and then the nozzles on the water outlet pipe 203 can be driven to rotate downward through the mounting ring 227, so that the two groups of nozzles can rotate downward while moving downward, and the area near the base 1 can be fully irrigated through the nozzles, so that the nozzles on the water outlet pipe 203 can reciprocate up and down while reciprocating in the horizontal plane, and can reciprocate, thereby fully expanding the irrigation range of the nozzles.

9. An irrigation method for a water-saving gardening irrigation device, using a water-saving gardening irrigation device according to any one of claims 1 to 8, the method steps are as follows: Step 1: When irrigating the garden, water is added to the water tank (101) through the water inlet (102), and the water pump (103) is started to pump water from the water tank (101), so that the water in the water tank (101) enters the hollow disk (201) through the hollow pipe (104) and the connecting pipe (202), and is then sprayed out through the nozzle on the water outlet pipe (203). The driving motor (204) is started to drive the rotating shaft (206) to rotate, and the rotating shaft (206) drives the driving gear (208) to rotate after the rotating shaft (206) rotates. The driving gear (208) drives the hollow disk (201) to rotate by meshing with the inner gear ring (205), so that the spraying range of the water outlet pipe (203) is more uniform. When the hollow disk (201) rotates, the two groups of spherical parts (212) slide inside the limiting ring (211), so that the hollow disk (201) is sprayed more evenly. 01), the hollow disk (201) rotates and drives the two sets of sliding rods (215) to rotate in a circle. When the sliding rod (215) rotates, the ball (217) rolls on the inner protrusion (216) of the fixing ring (210), and then the ball (217) pushes the sliding rod (215) to slide on the support frame (214), and the telescopic spring (218) is stretched, thereby pulling the nozzle on the water outlet pipe (203) to move. After the ball (217) leaves the protrusion (216), the telescopic spring (218) drives the sliding rod (215) to reset, so that the irrigation range moves back and forth on the horizontal plane, so that the irrigation range is increased while the garden is irrigated, and the area near the water tank (101) is irrigated, so as to ensure uniform irrigation, improve irrigation effect, avoid repeated irrigation and save water; Step 2: The hollow disk (201) rotates to drive the nozzle on the water outlet pipe (203) to reciprocate in the horizontal plane, and the fixed sleeve (219) is driven to move by the movement of the sliding rod (215). The fixed sleeve (219) moves close to the support frame (214). When the fixed sleeve (219) moves, the connecting rod (224) between the mounting frame (223) rotates. The connecting rod (224) rotates to push the sliding block (222) to slide inside the fixed sleeve (219). The movement of the sliding block (222) drives the moving rod (220) to slide on the fixed sleeve (219), thereby pulling the nozzles on the water outlet pipe (203) to move up and down. The two groups of nozzles on the water outlet pipes (203) are irrigated in an umbrella shape under the rotation of the hollow disk (201). The nozzles on the water outlet pipes (203) are lowered while approaching the hollow disk (201), so that the area around the base (1) is fully irrigated, the irrigation range is increased, and the irrigation effect of the garden is improved; Step 3: The two moving rods (220) pull the two rotating gears (230) downward while descending. The two rotating gears (230) rotate by meshing with the racks (229) on the support rods (228) while descending, thereby driving the rotating rod (225) to rotate. After the rotating rod (225) rotates, it drives the mounting block (226) to rotate, thereby driving the nozzles on the water outlet pipe (203) to rotate downward through the mounting ring (227), thereby causing the two groups of nozzles to move downward while moving downward, thereby fully irrigating the area near the base (1) through the nozzles, so that the nozzles on the water outlet pipe (203) reciprocate up and down while reciprocating in the horizontal plane, and reciprocate, thereby fully expanding the irrigation range of the nozzles, ensuring the uniformity of irrigation, avoiding repeated irrigation, improving the uniformity of irrigation, and achieving a water-saving effect.
