Description

Technical Field

[0001] This invention belongs to the field of irrigation equipment, specifically a water-saving drip irrigation device for string-harvest tomato planting. Background Technology

[0002] Cluster tomatoes, as a high-value-added premium fruit and vegetable in facility agriculture, are characterized by continuous fruiting, harvesting in clusters, and uniform quality. They are widely used in intensive farming scenarios such as intelligent greenhouses and elevated substrate cultivation. They have a long growth cycle, a large number of fruits per plant, shallow root systems, and extremely high requirements for stable water and fertilizer supply. Water demand peaks during fruit enlargement, and water stress can easily lead to stunted fruit, hollow centers, cracking, and decreased quality. Excessive irrigation, on the other hand, causes root hypoxia, nutrient leaching, and water waste. Currently, the cultivation of cluster tomatoes in facilities is transitioning from traditional soil cultivation to soilless substrate cultivation using coconut coir, rock wool, etc. Irrigation methods are gradually shifting from manual flooding and furrow irrigation to drip irrigation. To improve root water absorption and avoid excessive evaporation and water waste, drip irrigation is the optimal method. In use, drip irrigation equipment, such as drip heads, is inserted into the ground, positioned close to the tomato root system to improve irrigation efficiency and water conservation. However, the following drawbacks still exist: When the drip irrigation head is inserted into the ground, soil and other debris can easily enter the water outlet cavity of the drip irrigation head, causing blockage and affecting the subsequent irrigation effect.

[0010] Preferably, the water inlet switch includes baffles that are equally spaced inside the water inlet cylinder. The bottom wall of the baffles is in close contact with the inner bottom wall of the water inlet cylinder, so that each baffle closes the top of each connecting groove. A guide groove is provided inside the baffles. A guide fixing plate is installed at an equal angle on the inner wall of the water inlet cylinder.

A rod groove 404 is coaxially formed inside the insertion rod 403. The bottom end of the rod groove 404 is provided with a bottom groove 405, the bottom end of the bottom groove 405 extends to the bottom of the insertion rod 403, the top end of the rod groove 404 is provided with a piston groove 406, the piston groove 406 extends to the inside of the water inlet cylinder 401, the insertion rod 403 is provided with a movable separation member 407, and the insertion rod 403 is provided with a water outlet irrigation member 408. The movable separation member 407 is used to impact the ground so that it can be inserted into the ground, and at the same time, it works with the water outlet irrigation member 408 to achieve the anti-mud function.

[0018] Depend on Figure 1As shown, a sliding block 3 is fixedly installed on one side of the water inlet cylinder 401.

[0019] Depend on Figure 3 The movable separator 407 includes a movable rod 4071 movably mounted inside the rod groove 404. A limit stop 4072 is fixedly mounted at the bottom end of the movable rod 4071. The limit stop 4072 is located inside the bottom groove 405, and its outer wall contacts the inner wall of the bottom groove 405. A drilling cone 4073 is fixedly mounted at the bottom end of the limit stop 4072 and is located below the insertion rod 403. A piston block 4074 is fixedly mounted at the top end of the movable rod 4071 and is movably mounted in the piston groove 406.

The drilling cone 4073 is located at the bottom of the insertion rod 403 and fixed to the bottom of the limiting stop 4072. When the insertion rod 403 moves downward as a whole, it can generate pressure on the drilling cone 4073, making it easier to insert into the ground through the drilling cone 4073. When the piston block 4074 is subjected to water pressure, it can continue to move downward through the drilling cone 4073, causing the limiting stop 4072 to leave the bottom groove 405, facilitating water irrigation. The top of the piston block 4074 is connected to a water inlet switch 409.

[0020] Depend on Figures 4-5The irrigation component 408 includes a water outlet groove 4081 formed inside the insertion rod 403.

A connecting groove 4082 is formed at an equal angle at the top of the water outlet groove 4081, and the top of the connecting groove 4082 extends into the water inlet cylinder 401. Water outlet holes 4083 are evenly formed on the side of the water outlet groove 4081 away from the bottom groove 405, and connecting holes 4084 are evenly formed on the side of the water outlet groove 4081 near the bottom groove 405. Hole 4083 corresponds one-to-one with connecting hole 4084, and outlet hole 4083 and connecting hole 4084 are coaxially arranged. Outlet hole 4083 extends to the outside of insertion rod 403, and connecting hole 4084 extends to the inside of bottom groove 405. Movable plate 4085 is provided inside outlet groove 4081. A stop block 4086 is fixedly installed on the side of movable plate 4085 away from bottom groove 405. Stop block 4086 is located inside outlet hole 4083, and the side of movable plate 4085 near bottom groove 405 is fixed. A limit block 4087 is installed inside the connecting hole 4084. A sealing gasket is provided between the outer wall of the limit block 4087 and the inner wall of the connecting hole 4084. A hemispherical head 4088 is provided at the end of the limit block 4087, and the end of the hemispherical head 4088 contacts the outer wall of the limit stop 4072. A return spring 4089 is fixedly installed on the side of the movable plate 4085 near the limit block 4087. One end of the return spring 4089 is near the bottom of the water outlet 4081. The inner wall of one side of the groove 405 is fixedly connected, the return spring 4089 is in a stretched state, the water outlet 4083 is set on the side of the insertion rod 403 to realize water irrigation, and the water outlet 4083 is provided with a stop block 4086 to prevent soil from entering the water outlet 4083 when it is inserted into the ground, thus playing a role in preventing blockage and improving irrigation smoothness. When the limit stop rod 4072 no longer limits the limit block 4087, the water outlet 4083 opens to realize irrigation.

[0021] Depend on Figure 6The water inlet switch component 409 includes baffles 4092 disposed at equal angles inside the water inlet cylinder 401. The bottom wall of the baffles 4092 is in close contact with the inner bottom wall of the water inlet cylinder 401, so that each baffle 4092 closes the top of each connecting groove 4082. A guide groove 4093 is provided inside the baffles 4092. A guide fixing plate 4091 is installed at equal angles on the inner wall of the water inlet cylinder 401. The baffles 4092 are slidably installed outside the guide fixing plate 4091. A pressure ring 4094 is movably installed inside the water inlet cylinder 401. A connecting rod 4095 is hinged at equal angles to the bottom end of the pressure ring 4094. The connecting rod 4095 corresponds one-to-one with the baffles 4092. The bottom end is hinged to the corresponding baffle 4092. A connecting rod 4096 is fixedly installed between the pressure ring 4094 and the limiting rod 4072. The two ends of the connecting groove 4082 are connected to the water inlet cylinder 401 and the water outlet groove 4081, respectively. When the limiting rod 4072 is inside the bottom groove 405, the baffle 4092 closes the top of the connecting groove 4082, so that the water entering the water inlet cylinder 401 acts on the inside of the limiting rod 4072, thereby pushing the limiting rod 4072 away from the bottom groove 405 and opening the water outlet 4083. After the limiting rod 4072 is pushed away from the bottom groove 405, the baffle 4092 opens the connecting groove 4082 to realize irrigation and facilitate use.

[0022] Working principle: When in use, the device is installed near the location where the tomato plants need drip irrigation. Then, the drive motor 6 is turned on, which drives the screw 5 to rotate. Since the sliding block 3 is threadedly connected to the screw 5, the insertion rod 403 is driven to move downward. Then, through the drilling cone 4073, the insertion rod 403 is continuously inserted into the ground, so that during drip irrigation, the water can directly enter the ground and be absorbed by the roots, reducing water evaporation and improving water-saving effect. After insertion to the appropriate depth, the drive motor 6 is stopped, and then the water pump in the water tank is turned on. The water pump drives the water in the water tank to enter the water inlet cylinder 401 through the hose and the water inlet pipe 402. Since the piston groove 406 is connected to the water inlet cylinder 401, the water pressure acts on the top of the piston block 4074, which generates downward pressure on the drilling cone block 4073, causing the drilling cone block 4073 to move downward continuously until the piston block 4074 moves downward to the limit position in the piston groove 406. At this time, the limit stop bar 4072 moves out from the bottom groove 405. When the limit stop 4072 moves downward, since the limit stop 4072 no longer limits one end of the limit block 4087, and the return spring 4089 is in a stretched state in the original state, the limit block 4087 moves towards the bottom groove 405 under the elastic force of the return spring 4089, and the stop block 4086 moves out of the water outlet 4083, thereby opening each water outlet 4083; Simultaneously, the limiting stop bar 4072 moves downward, pulling the pressure ring 4094 downward. Then, through each connecting rod 4095, it pushes each baffle 4092 to move along the guide fixing plate 4091 until the baffle 4092 no longer seals the top of the connecting groove 4082. At this time, the water no longer exerts pressure on the top of the limiting stop bar 4072, but enters the water outlet groove 4081 from each connecting groove 4082, and then enters the soil from the evenly opened water outlet holes 4083 to achieve irrigation.
