Description

TECHNICAL FIELD

[0001] The application relates to the technical field of irrigation devices, in particular to a rotatable irrigation device for irrigation in land space ecological restoration. BACKGROUND

[0002] Land space ecological restoration is an activity that follows the succession law of the ecological system, is guided by land space planning, and systematically restores the areas with degraded ecological function, damaged ecological system and unbalanced spatial pattern, aiming to improve the quality and stability of the ecological system and maintain national ecological security.

[0003] The current sprinkler device is prone to clogging due to the invasion of external impurities at the nozzle part during long-term operation in the open environment, which causes abnormal water discharge function and affects the overall operation efficiency. Although the current mainstream sprinkler equipment generally uses a built-in filter screen structure to achieve primary water filtration, this design can only intercept suspended particles in the water, and there is still a lack of effective protection and removal measures for the problem of external solid impurities invading the nozzle aperture caused by factors such as wind action and crop branch rubbing during field operation. For example, refer to the patent for utility model with publication number CN209861851U, an energy-saving sprinkler device for farmland water use, which filters water through the first filter screen and the second filter screen, but external soil or other impurities entering the nozzle will still cause clogging. Secondly, the current widely used rotatable irrigation device has a limited spraying coverage range due to the inherent length of the nozzle and the fixed installation method, resulting in a fixed effective irrigation area. This design defect is manifested in the following aspects in specific applications: when applied to a small area irrigation area, the sprinkling radius exceeds the actual demand, resulting in excessive waste of water resources; and when facing a large area of soil restoration area, the single device coverage capacity is insufficient, and the number of nozzles needs to be increased to make up for it, which not only increases the equipment procurement and installation cost, but also increases the difficulty of later maintenance due to the increase of system complexity. For example, refer to the patent application with publication number CN209201723U, a sprinkler device for farmland water conservancy, which cannot adjust the length and installation posture of the spray pipe, so it can only be used for sprinkling irrigation of fixed area farmland, and cannot adjust the spraying range according to the farmland area, resulting in inconvenient irrigation operation.

[0034] Through the detachable design of the main and secondary water spraying units, the main water spraying unit 291 can be used alone or connected with the secondary water spraying unit 292 through threads to expand the spraying range, the design of the bearing ring 2923 and the limiting rod 2924 of the secondary water spraying unit 292 ensures that the main water spraying hole is automatically blocked after installation, only the second spraying hole of the secondary water spraying unit 292 is used for water outlet, the flexible expansion of the irrigation range is realized, the modular structure design of the main and secondary water spraying units can reduce the equipment replacement cost, and different crops and terrain requirements can be met.

[0035] In the embodiment, the inner part of the movable groove 2914 is uniformly provided with through holes 2915 corresponding to the first spray hole positions one by one, and each through hole 2915 is slidably provided with a sealing column 2916, one end of the sealing column 2916 extends into the first spray hole at the opposite position and forms a sealed connection with the first spray hole, a limiting ring 2917 is fixedly sleeved on the outer wall of the sealing column 2916 and located in the inner part of the main water pipe 2911, one end of the plurality of sealing columns 2916 is commonly and fixedly provided with a pressure bearing plate 2918, a spring 2919 is slidably sleeved on the outer wall of the sealing column 2916 and located between the pressure bearing plate 2918 and the movable groove 2914, and the end of the pressure bearing plate 2918 close to the auxiliary water spraying unit 292 is also provided with a limiting hole 29110.

[0036] Through the automatic unblocking design of the sealing column 2916 and the spring 2919 structure, when the water spraying assembly 29 is retracted, the spring 2919 pushes the pressure bearing plate to make the sealing column 2916 enter the first spray hole, discharges the impurities and gas in the hole, and prevents blockage, which does not need manual intervention and prolongs the service life of the equipment; secondly, when irrigation is stopped, the water spraying assembly 29 is tightly attached to the outer wall of the conical bearing cylinder 21 due to gravity, and the spray hole is automatically sealed, reducing the maintenance requirement.

[0038] As Figure 12The third embodiment is shown, which is different from the second embodiment in that the suction assembly 211 comprises first suction units 2111, second suction units 2112, third suction units 2113, fourth suction units 2114 and fifth suction units 2115 which are structurally identical and arranged in a ring array, the first suction unit 2111 comprises a Venturi tube a1 and a drainage tube a2 fixedly connected to one end of the Venturi tube a1, one end of the drainage tube a2 is fixedly provided with a hose a3 for conveying clean water to one of the water spraying assemblies 29, the Venturi tubes a1 in the first suction units 2111, the second suction units 2112, the third suction units 2113, the fourth suction units 2114 and the fifth suction units 2115 are fixedly connected to each other in the middle part, and a hollow cavity is formed in the connected part, the top of the inner cavity of the hollow cavity is fixedly provided with a catheter, the catheter penetrates through the hollow cavity and penetrates to the outside of the rotating water spraying mechanism 2. One end of the Venturi tube a1 is in an open state for clean water to enter, and the other end is used to connect the drainage tube a2.

[0039] By designing the suction assembly, the Venturi tube a1 principle is used to generate negative pressure when the water flows, automatically sucking the water and fertilizer in the spraying auxiliary assembly 3, and spraying after mixing with clean water, realizing synchronous irrigation and fertilization, and adjusting the overlapping area of the first arc-shaped air inlet 33 and the second arc-shaped air inlet 35 through the rotating sealing plate 34 to accurately control the air flow in the storage cylinder 31, thereby adjusting the water and fertilizer flow rate, for example, the larger the air inlet, the faster the flow rate, avoiding waste of fertilizer and improving the uniformity of fertilization.

[0040] The specific process is: if no water and fertilizer is applied, the water inlet at the top of the rotating joint 223 needs to be plugged with a sealing plug before land space ecological restoration irrigation, if liquid fertilizer needs to be applied to the soil at the same time of land space ecological restoration irrigation, the output end of the spraying auxiliary assembly 3 at the bottom needs to be connected to the input end at the top of the rotating joint 223, and then the spraying auxiliary assembly 3 is stably fixed on the outer wall of the bearing plate 4 through bolts.

[0041] Next, the water pipe 1 and the external water source are connected, and the water flow is transported through the water pipe 1 and into the plurality of rotating water spraying mechanisms 2, the water flow flows into the volute 24 through the support pipe 23 and the guide pipe 27 in the rotating water spraying mechanism 2, and directly impacts the surface of the impeller 25 to make the impeller 25 rotate, the impeller 25 rotates at the same time to drive the transmission pipe 26 to rotate, thereby using the transmission pipe 26 to drive the rotating assembly 22 to rotate synchronously, the clean water in the volute 24 enters the inside of the transmission pipe 26 through the plurality of water inlet holes on the outer wall of the transmission pipe 26 and then flows into the conical rotating cylinder 221, the water flow enters the drainage pipe a2 through the one end of the Venturi tube a1 in the first suction unit 2111, the second suction unit 2112, the third suction unit 2113, the fourth suction unit 2114 and the fifth suction unit 2115, and flows into the water spraying assembly 29 at the corresponding position through the hose a3.

[0042] At the same time, when the conical rotating cylinder 221 rotates, the plurality of water spraying assemblies 29 on the outer wall of the conical rotating cylinder 221 are synchronously thrown up under the action of centrifugal force, when the water spraying assembly 29 moves away from the conical rotating cylinder 221, the pressure bearing plate 2918 loses the pushing force of the outer wall of the conical rotating cylinder 221 and is pushed by the spring 2919 in the direction away from the first spray nozzle 2913, so that the first spray hole is exposed, the water flow in the main water pipe 2911 flows into the first spray nozzle 2913 at the corresponding position through the plurality of first spray holes, and is sprayed in the surrounding soil to be repaired through the first spray nozzle 2913, when the irrigation is finished, the conical rotating cylinder 221 stops rotating without water flow passing through, and the plurality of water spraying assemblies 29 adhere to the outer wall of the conical bearing cylinder 21 due to gravity, the pressure bearing plate 2918 is pushed by the pushing force of the outer wall of the conical bearing cylinder 21 to push the sealing column 2916 at a plurality of positions into the first spray hole at the corresponding position, the sealing column 2916 pushes out the gas in the first spray hole after entering the first spray hole, the impurities in the first spray hole are pushed out together with the gas, and the operation of cleaning the first spray hole is completed.

[0043] In the state that the bottom output end of the spray auxiliary assembly 3 is connected with the input end of the rotary joint 223, when the water flow flows through the Venturi tube a1, according to the Venturi principle, the pressure at the middle thin position of the Venturi tube a1 is smaller than the pressure at the two ends, the water and fertilizer in the spray auxiliary assembly 3 is sucked into the hollow cavity composed of multiple Venturi tubes a1, and the part of the water and fertilizer is mixed with the flowing water and then sprayed into multiple water spraying assemblies 29, the size of the overlapping area of the second arc-shaped air inlet 35 and the first arc-shaped air inlet 33 is controlled by the knob at the top of the rotary sealing plate 34, when the overlapping area of the second arc-shaped air inlet 35 and the first arc-shaped air inlet 33 increases, the amount of air entering the storage cylinder 31 per unit time increases, and the water and fertilizer in the storage cylinder 31 flows out faster, and vice versa, when the overlapping area of the second arc-shaped air inlet 35 and the first arc-shaped air inlet 33 decreases, the amount of air entering the storage cylinder 31 per unit time decreases, and the water and fertilizer in the storage cylinder 31 flows out slower.

[0044] When it is necessary to control the flinging angle of the water spraying assembly 29 to control the irrigation range, the distance between the end of the rotating screw 2103 and the baffle 2101 is adjusted, in the state that the end of the screw 2103 is close to the baffle 2101, after the water spraying assembly 29 is flung to a certain angle, the baffle 2101 is blocked by the screw 2103 and cannot continue to increase the flung angle, thereby controlling the spraying range, and for the same reason, the distance between the screw 2103 and the baffle 2101 is gradually increased within a certain range, so that the baffle 2101 rotates to a larger angle before it abuts against the end of the screw 2103, thereby increasing the flung angle of the water spraying assembly 29 at the corresponding position, and increasing the spraying range of the water spraying assembly 29.

[0045] In addition, when it is necessary to further increase the irrigation range, the sealing plug at the end of the main water pipe 2911 is removed, the end of the auxiliary water pipe 2921 is sealed and screwed into the main water pipe 2911, and at the same time that the auxiliary water pipe 2921 is inserted into the main water pipe 2911, the limiting rod 2924 is aligned with the limiting hole 29110, so that the auxiliary water pipe 2921 and the limiting rod 2924 are synchronously inserted into the main water pipe 2911 and the limiting hole 29110 respectively, and since the pressure-bearing plate 2918 cannot move in the movable groove 2914 after the limiting rod 2924 is inserted into the limiting hole 29110, multiple first spraying holes are blocked, during irrigation, the clear water can only flow into the auxiliary water spraying unit 292 through the main water spraying unit 291, and is sprayed out through multiple second spraying holes on the outer wall of the auxiliary water spraying unit 292, thereby increasing the spraying irrigation range.
