Description

Technical Field

[0001] The invention relates to the technical field of irrigation, and in particular to an irrigation device for cultivating almond trees in saline-alkali land. Background Art

[0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline soil and alkaline soil in my country is mostly related to the accumulation of carbonates in the soil, so the alkalinity is generally high, and plants can hardly survive in areas with severe saline-alkali soil.

[0003] Apricot trees have very strong vitality and can grow and bear fruit in mountains, plains, hills, sandy wastelands, dry lands and saline-alkali lands. They are also one of the oldest fruit trees cultivated in my country. The soil pH required for the growth of apricot trees is between 6.8 and 7.9, and they can also be planted in saline-alkali lands with a pH value of 5.

[0004] However, the pH value of saline-alkali land cannot exceed the pH value of the soil where apricot trees grow excessively, otherwise it will affect the growth of apricot trees or even kill them. Due to the low precipitation in saline-alkali land, some saline-alkali lands lack water resources. The salt inside the soil slowly moves to the upper layer of the soil with the evaporation of water to form crystals. At present, the commonly used methods for saline-alkali land are usually salt washing and drip irrigation. Salt washing is to irrigate the land with a large amount of water so that the salt in the land is dissolved by water and carried away by water flow. These two methods are more commonly used, but the two cannot be used at the same time due to equipment price issues. Therefore, an irrigation device for cultivating apricot trees in saline-alkali land is proposed. Summary of the invention

[0005] In view of this, the present invention provides an irrigation device for cultivating apricot trees in saline-alkali land to solve the problem that the pH value of the saline-alkali land cannot excessively exceed the pH value of the soil where the apricot trees grow, otherwise it will affect the growth of the apricot trees or even their death. Due to the low precipitation in the saline-alkali land, some saline-alkali lands are short of water resources. The salt inside the soil slowly moves to the upper layer of the soil with the evaporation of water to form crystals. Currently, the commonly used methods for saline-alkali land are usually salt washing and drip irrigation. Salt washing is to irrigate the land with a large amount of water so that the salt in the land is dissolved by water and carried away by the water flow. These two methods are more commonly used, but the two cannot be used at the same time due to equipment price issues.

[0007] Furthermore, the pressure regulating assembly includes a piston column, which is matched with the shunt pipe, and the end of the piston column away from the inlet pipe is slidably connected with a connecting column, and a compression spring is provided between the piston column and the connecting column. The end of the connecting column away from the piston column is fixedly connected to a base, and the end of the base away from the connecting column is rotatably connected to a threaded rod, and the threaded rod is threadedly connected to the bottom of the shunt pipe.

[0008] Furthermore, a plurality of water spray heads and a support seat are provided on the surface of the annular spray pipe, and the support seat is used to support the annular spray pipe and the water spray heads, so that the water spray heads are always placed upwards.

[0009] Furthermore, the water level regulating assembly includes a shell, the shell is provided with a water inlet channel and a water outlet channel, the water inlet channel and the water outlet channel are connected, and the lower end of the water outlet channel is disconnected from the sealing column by a sealing column.

[0010] Furthermore, the water level regulating assembly further comprises a sealing plate, the upper end of which is fixedly connected with a sealing ring, and the upper end of which is fixedly connected with a sealing column via a bellows; The upper end of the sealing plate is fixedly connected with a sealing column, and the sealing plate is in contact with the sealing column.

[0011] Furthermore, the water level regulating assembly also includes a fixed column, which is fixedly connected to the shell, and the fixed column is slidably sleeved with a floating column matching the shell, and the upper end of the floating column contacts a pushing member, and the pushing member is shaped like a harpoon, and one end of the pushing member close to the fixed column is slidably sleeved with the fixed column, and the pushing member is rotatably connected to the bottom of the sealing plate through a connecting seat.

[0012] Furthermore, a water outlet hole is provided at the lower end of the sealing plate, a sealing ball matching the water outlet hole is provided at the upper end of the pushing member, and a water inlet is provided at the upper end of the sealing ring.

[0013] Furthermore, a water leakage hole is provided at the lower end of the shell.

[0014] Furthermore, a water-absorbing cloth is provided at the bottom of the drip pipe.

[0015] Furthermore, a valve is installed at one end of the inlet pipe close to the diversion pipe.

[0016] The invention provides an irrigation device for cultivating almond trees in saline-alkali land, which has the following beneficial effects: When the present invention is in use, through the water level regulating component, when drip irrigation is required, water flows into the dropper cup through the shunt pipe. At this time, due to the limitation of the pressure regulating component, the annular spray pipe cannot irrigate through the annular spray pipe. At this time, the water tank can be pumped in an appropriate amount to ensure that there is water in the water tank continuously. The water in the water tank can flow downward by gravity. After the water flows into the inside of the dropper cup, the water enters the inside of the shell from the water inlet channel. At this time, the water pressure inside the shell moves the sealing column downward. At this time, the sealing column cannot block the water outlet channel. The water flows into the inside of the dropper cup along the water outlet channel. A small amount of water flows downward through the sealing ring and the sealing plate. This process does not require other power and can be completed by relying on the power of water. After the water level inside the dropper cup reaches a certain position, after the water contacts the shell, the water enters the shell from the water leakage hole of the shell. At this time, the floating column moves upward due to buoyancy, driving the floating column to move upward along the fixed column. The upward movement of the floating column drives the pushing member to move upward. At this time, the pushing member is in the shape of a harpoon. The fixed column is inserted into the end of the pushing member close to the fixed column. The pusher is effectively limited in position. After the pusher moves upward, the sealing ball on the pusher blocks the water outlet on the sealing plate. At this time, water entering from the shell can no longer flow downward through the water outlet. The water outlet divides the shell into two closed spaces. Since the pressure inside the sealing ring is consistent with the pressure of the external shell, the water pressure inside the shell exerts a smaller pressure on the sealing column. The elastic force drives the sealing column to move upward to block the water outlet channel. At this time, water can no longer flow into the dropper cup. After the water level drops, the floating column can no longer squeeze the pusher. The pressure pushes the member downward, and the water outlet hole of the sealing plate cannot be blocked, so the sealing column moves downward due to the water pressure, and the water enters the interior of the dropper cup through the water outlet channel again to replenish the dropper cup, thereby achieving the effect of keeping the dropper cup full of water. This process does not require other power to provide control, and only needs to keep water in the water tank. The water in the dropper cup flows into the drip pipe. Since the drip pipe is equipped with absorbent cloth, the water can be kept flowing into the soil, and the soil can be effectively prevented from entering the drip pipe to cause the drip pipe to be blocked. When the present invention is in use, through the pressure regulating component, when it is necessary to irrigate the soil by washing salt, firstly, the water tank is continuously pumped by the water pump, and then multiple valves are closed, and only one valve is left open. At this time, the water pressure in the shunt pipe is high. Since the water pressure inside the shunt pipe is high, it cannot flow out from the dropper cup, and the water level in the dropper cup is full. At this time, the water pressure drives the piston column to move in the direction of the annular spray pipe, and the piston column moves along the direction of the connecting column to squeeze the compression spring. The piston column no longer blocks the water inlet channel of the annular spray pipe, and water can enter the interior of the annular spray pipe, and irrigate the apricot tree through the sprinkler head. The spray pipe is a circular tube, which can wrap the apricot tree in the center of the circular spray pipe. The sprinkler heads are distributed in a ring, which can dissolve and dilute the salt around the apricot tree and carry it away through the water flow. The support base is a placement rack, which is usually placed in contact with the ground, which can effectively prevent the circular spray pipe from tilting and avoid the sprinkler head from directly contacting the ground, resulting in reduced water spraying effect. When one section of irrigation is completed, open the next valve and close the previous valve, leaving only one valve for irrigation. This can effectively irrigate the soil and has a long service life. There is no need to lay water pipes every time for irrigation, and it is convenient to operate without affecting irrigation.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 to Figure 7 , Embodiment 1: The present invention proposes an irrigation device for cultivating almond trees in saline-alkali land, comprising a water tank 1, an annular spraying pipe 7 and a dropper cup 8; a water pump 2 is installed at the upper end of the water tank 1, an inlet pipe 3 is fixedly connected to the upper end of the water pump 2, an outlet pipe 4 is fixedly connected to the lower end of the water tank 1, a plurality of inlet pipes 5 are fixedly connected to both sides of the outlet pipe 4, a plurality of shunt pipes 6 are fixedly connected to one side of the plurality of inlet pipes 5, both sides of the plurality of shunt pipes 6 are fixedly connected to the annular spraying pipe 7 and the dropper cup 8, a pressure regulating assembly 11 is installed at one end of the shunt pipe 6 close to the dropper cup 8, and a dripping pipe 13 is fixedly connected to the lower end of the dropper cup 8.

[0023] Water enters the water tank 1 from the water inlet pipe 3 through the water pump 2. The height of the water tank 1 is higher than the water outlet pipe 4 and the inlet pipe 5, so that the water can fall directly from the water tank 1. The water pump 2 is mainly used to facilitate water pumping. When drip irrigation is needed, it is only necessary to fill the water inside the water tank 1 through the water pump 2. The water inside the water tank 1 flows into the inside of the water outlet pipe 4 by gravity, and then flows into the dropper cup 8 through the inlet pipe 5 and the diversion pipe 6. At this time, the water inside the dropper cup 8 is kept full of water through the water level regulating component 12, and then flows into the absorbent cloth 10 through the drip pipe 13. The drip pipe 13 is inserted into the soil and slowly flows into the soil through the absorbent cloth 10 to drip irrigate the apricot tree. , which can effectively prevent water evaporation and save water; when it is necessary to wash salt from the soil, the water inside the dropper cup 8 is automatically cut off after the water inside the dropper cup 8 is full because the water level regulating component 12 is set. At this time, multiple valves 9 are closed, and only one valve 9 is left open. Then, the water tank 1 is continuously pumped by the water pump 2 to keep the pressure inside the water tank 1 increased. At this time, the pressure regulating component 11 moves backward to open the channel to the dropper cup 8, and the apricot tree is irrigated through the annular spray pipe 7. Due to the high water pressure, more water flows out of the annular spray pipe 7 at this time, which can effectively irrigate the saline-alkali land. A large amount of water can effectively take away the salt on the surface of the soil and reduce the pH value of the soil.

[0024] Preferably, the water level regulating assembly 12 comprises a housing 1201, the housing 1201 is provided with a water inlet channel 1202 and a water outlet channel 1203, the water inlet channel 1202 and the water outlet channel 1203 are connected, and the lower end of the water outlet channel 1203 is disconnected from the water outlet channel 1203 by a sealing column 1204; Preferably, the water level regulating assembly 12 further comprises a sealing plate 1206, the upper end of the sealing plate 1206 is fixedly connected with a sealing ring 1205, and the upper end of the sealing ring 1205 is fixedly connected to the sealing column 1204 via a bellows 1211; The upper end of the sealing plate 1206 is fixedly connected with 1212 , and the sealing plate 1206 is in contact with the sealing column 1204 .

[0025] After the water flows into the dropper cup 8 through the shunt pipe 6, the annular spray pipe 7 cannot be irrigated due to the limitation of the pressure regulating component 11. At this time, the water tank 1 can be pumped out in an appropriate amount to ensure that there is water in the water tank 1 continuously. The water in the water tank 1 can flow downward by gravity. After the water flows into the dropper cup 8, the water enters the shell 1201 from the water inlet channel 1202. At this time, the water pressure in the shell 1201 moves the sealing column 1204 downward. At this time, the sealing column 1204 cannot block the water outlet channel 1203. The water flows into the dropper cup 8 along the water outlet channel 1203. A small amount of water passes through the sealing ring 1205 and The sealing plate 1206 flows downward, and this process does not require other power and can be completed by relying on the power of water. After the water level inside the dropper cup 8 reaches a certain position, after the water contacts the shell 1201, the water enters the shell 1201 from the leaking hole 1209 of the shell 1201. At this time, the floating column 1207 moves upward due to the buoyancy, driving the floating column 1207 to move upward along the fixed column 1208. The upward movement of the floating column 1207 drives the pushing member 1210 to move upward. At this time, the shape of the pushing member 1210 is a harpoon. The fixed column 1208 is inserted into the end of the pushing member 1210 close to the fixed column 1208, which can effectively limit the pushing member 1210. After the blocking ball 12101 moves upwards, the blocking ball 12101 blocks the water outlet hole 12061 on the sealing plate 1206. At this time, the water entering from the shell 1201 can no longer flow downwards through the water outlet hole 12061. The water outlet hole 12061 divides the shell 1201 into two closed spaces. Since the pressure inside the sealing ring 1205 is consistent with the pressure of the external shell 1201, the water pressure inside the shell 1201 exerts less pressure on the sealing column 1204. The sealing column 1204 is driven to move upwards through the elastic force of 1212 to block the water outlet channel 1203. At this time, the water can no longer flow into the interior of the dropper cup 8. After the water level drops, the floating column 120 7 cannot squeeze the push member 1210, the push member 1210 moves downward, and the water outlet hole 12061 of the sealing plate 1206 cannot be blocked, which causes the sealing column 1204 to move downward due to the water pressure, and the water enters the interior of the dropper cup 8 through the water outlet channel 1203 again, replenishing the dropper cup 8 with water, thereby achieving the effect of keeping the dropper cup 8 full of water. This process does not require other power to provide control, and only needs to keep the water inside the water tank 1. The water inside the dropper cup 8 flows into the drip pipe 13. Since the drip pipe 13 is equipped with a water-absorbing cloth 10, the water can be kept flowing into the soil, and the soil can be effectively prevented from entering the drip pipe 13 to cause the drip pipe 13 to be blocked.

[0026] The upper end of the sealing plate 1206 is fixedly connected with 1212 , and the sealing plate 1206 is in contact with the sealing column 1204 .

[0027] The sealing column 1204 can be made of plastic to save costs, and the bellows 1211 is a bellows to facilitate the up and down movement of the sealing column 1204.

[0028] Preferably, the water level regulating assembly 12 also includes a fixed column 1208, which is fixedly connected to the shell 1201. The fixed column 1208 is slidably sleeved with a floating column 1207 matching the shell 1201. The upper end of the floating column 1207 contacts a pushing member 1210. The pushing member 1210 is shaped like a harpoon. One end of the pushing member 1210 close to the fixed column 1208 is slidably sleeved with the fixed column 1208. The pushing member 1210 is rotatably connected to the bottom of the sealing plate 1206 through a connecting seat.

[0029] At this time, the pushing member 1210 is shaped like a harpoon. Inserting the fixed column 1208 at the end of the pushing member 1210 close to the fixed column 1208 can effectively limit the pushing member 1210. One end of the pushing member 1210 is rotatably connected to the sealing plate 1206 through a connecting seat, which serves the purpose of supporting the rotation of the pushing member 1210. This technology is easy to understand for people in this field, so it will not be elaborated on.

[0030] Preferably, a water outlet hole 12061 is provided at the lower end of the sealing plate 1206, a sealing ball 12101 matching the water outlet hole 12061 is provided at the upper end of the pushing member 1210, a water inlet 12051 is provided at the upper end of the sealing ring 1205, and a water leakage hole 1209 is provided at the lower end of the shell 1201.

[0031] A small amount of water and air enters the interior of the sealing plate 1206 through the water inlet 12051, and then flows out through the water outlet 12061. The water level regulating component 12 relieves the pressure inside the shell 1201. The water can rely on the pressure to move the sealing column 1204 downward, opening the water outlet channel 1203. After the water level reaches a certain height, the water outlet 12061 is blocked by the sealing ball 12101, causing the pressure of the shell 1201 and the sealing plate 1206 to remain consistent. Under the action of the elastic force of 1212, the water outlet channel 1203 is blocked, thereby achieving the purpose of water level regulation and control.

[0032] On the basis of the first embodiment, the second embodiment, as Figure 1 , Figure 2 as well as Figure 7 As shown: A saline-alkali land cultivation irrigation device for almond trees comprises a water tank 1, an annular spraying pipe 7 and a drip irrigation cup 8; a water pump 2 is installed at the upper end of the water tank 1, an inlet pipe 3 is fixedly connected to the upper end of the water pump 2, an outlet pipe 4 is fixedly connected to the lower end of the water tank 1, a plurality of inlet pipes 5 are fixedly connected to both sides of the outlet pipe 4, a plurality of shunt pipes 6 are fixedly connected to one side of the plurality of inlet pipes 5, both sides of the plurality of shunt pipes 6 are fixedly connected to the annular spraying pipe 7 and the drip cup 8, a pressure regulating assembly 11 is installed at one end of the shunt pipe 6 close to the drip cup 8, and a drip pipe 13 is fixedly connected to the lower end of the drip cup 8.

[0033] Water enters the water tank 1 from the water inlet pipe 3 through the water pump 2. The height of the water tank 1 is higher than the water outlet pipe 4 and the inlet pipe 5, so that the water can fall directly from the water tank 1. The water pump 2 is mainly used to facilitate water pumping. When drip irrigation is needed, it is only necessary to fill the water inside the water tank 1 through the water pump 2. The water inside the water tank 1 flows into the inside of the water outlet pipe 4 by gravity, and then flows into the dropper cup 8 through the inlet pipe 5 and the diversion pipe 6. At this time, the water inside the dropper cup 8 is kept full of water through the water level regulating component 12, and then flows into the absorbent cloth 10 through the drip pipe 13. The drip pipe 13 is inserted into the soil and slowly flows into the soil through the absorbent cloth 10 to drip irrigate the apricot tree. , which can effectively prevent water evaporation and save water; when it is necessary to wash salt from the soil, the water inside the dropper cup 8 is automatically cut off after the water inside the dropper cup 8 is full because the water level regulating component 12 is set. At this time, multiple valves 9 are closed, and only one valve 9 is left open. Then, the water tank 1 is continuously pumped by the water pump 2 to keep the pressure inside the water tank 1 increased. At this time, the pressure regulating component 11 moves backward to open the channel to the drip irrigation cup 8, and the apricot tree is irrigated through the annular spray pipe 7. Due to the high water pressure, more water flows out of the annular spray pipe 7 at this time, which can effectively irrigate the saline-alkali land. A large amount of water can effectively take away the salt on the surface of the soil and reduce the pH value of the soil.

[0034] The pressure regulating assembly 11 includes a piston column 1101, which is matched with the shunt tube 6. The end of the piston column 1101 away from the inlet tube 5 is slidably connected with a connecting column 1103, and a compression spring 1102 is provided between the piston column 1101 and the connecting column 1103. The end of the connecting column 1103 away from the piston column 1101 is fixedly connected with a base 1104, and the end of the base 1104 away from the connecting column 1103 is rotatably connected with a threaded rod 1105, and the threaded rod 1105 is threadedly connected to the bottom of the shunt tube 6.

[0035] When it is necessary to irrigate the soil for salt removal, firstly, the water tank 1 is continuously pumped through the water pump 2. At this time, multiple valves 9 are closed and only one valve 9 is left open. At this time, the water pressure in the shunt pipe 6 is high. Due to the high water pressure inside the shunt pipe 6, it cannot flow out from the dropper cup 8. The water level in the dropper cup 8 is full. At this time, the water pressure drives the piston column 1101 to move in the direction of the annular spray pipe 7. The piston column 1101 moves along the direction of the connecting column 1103, squeezing the compression spring 1102. The piston column 1101 no longer blocks the water inlet channel of the annular spray pipe 7. Water can enter the interior of the annular spray pipe 7 and irrigate the apricot trees through the sprinkler head 71. The annular spray pipe 7 is an annular The circular tube can wrap the apricot tree in the center of the circular spraying pipe 7. The sprinkler heads 71 ​​are distributed in a ring shape, which can dissolve and dilute the salt around the apricot tree and carry it away through the water flow. The support seat 72 is a placement rack. When placed, the support seat 72 is usually placed in contact with the ground, which can effectively prevent the circular spraying pipe 7 from tilting and avoid the sprinkler head 71 from directly contacting the ground, resulting in a decrease in the water spraying effect. When one section of irrigation is completed, the next valve 9 is opened and the previous valve 9 is closed, leaving only one valve 9 for irrigation. This can effectively irrigate the soil and has a long service life. There is no need to lay water pipes every time irrigation is carried out. It is convenient to operate without affecting irrigation and achieves the effect of one pipe for multiple uses.

[0036] The surface of the annular spray pipe 7 is provided with multiple water spray heads 71 ​​and a support seat 72. The support seat 72 is used to support the annular spray pipe 7 and the water spray heads 71. The water spray heads 71 ​​are always placed upward. A valve 9 is installed at one end of the inlet pipe 5 close to the diversion pipe 6 to irrigate the apricot tree through the water spray heads 71. The annular spray pipe 7 is an annular circular tube, which can wrap the apricot tree in the center of the annular spray pipe 7. The water spray heads 71 ​​are distributed in an annular manner, which can dissolve and dilute the salt around the apricot tree and carry it away through the water flow. The support seat 72 is a placement rack. When placed, the support seat 72 is usually in contact with the ground, which can effectively prevent the annular spray pipe 7 from tilting.

[0037] Working principle: when drip irrigation is needed, water flows into the dropper cup 8 through the shunt pipe 6. At this time, the annular spray pipe 7 cannot be irrigated due to the limitation of the pressure regulating component 11. At this time, the water tank 1 can be pumped in an appropriate amount to ensure that there is water in the water tank 1 continuously. The water in the water tank 1 can flow downward by gravity. After the water flows into the dropper cup 8, the water enters the shell 1201 from the water inlet channel 1202. At this time, the water pressure in the shell 1201 moves the sealing column 1204 downward. At this time, the sealing column 1204 cannot block the water outlet channel 1203, and the water flows into the dropper cup 8 along the water outlet channel 1203. A small amount of water The water flows downward through the sealing ring 1205 and the sealing plate 1206. This process does not require other power and can be completed by relying on the power of water. After the water level inside the drip irrigation cup 8 reaches a certain position, after the water contacts the shell 1201, the water enters the shell 1201 from the water leakage hole 1209 of the shell 1201. At this time, the floating column 1207 moves upward due to the buoyancy, driving the floating column 1207 to move upward along the fixed column 1208. The upward movement of the floating column 1207 drives the pushing member 1210 to move upward. At this time, the pushing member 1210 is in the shape of a harpoon. The fixed column 1208 is inserted into the end of the pushing member 1210 close to the fixed column 1208, which can effectively limit the pushing member 1210. After the blocking ball 12101 on the movable member 1210 moves upward, the blocking ball 12101 blocks the water outlet hole 12061 on the sealing plate 1206. At this time, the water entering from the shell 1201 can no longer flow downward through the water outlet hole 12061. The water outlet hole 12061 divides the shell 1201 into two closed spaces. Since the pressure inside the sealing ring 1205 is consistent with the pressure of the external shell 1201, the water pressure inside the shell 1201 exerts a smaller pressure on the sealing column 1204. The sealing column 1204 is driven to move upward through the elastic force of 1212 to block the water outlet channel 1203. At this time, water can no longer flow into the interior of the dropper cup 8. After the water level drops, the floating column 1205 is 1207 cannot squeeze the pusher 1210, and the pusher 1210 moves downward, and cannot block the water outlet 12061 of the sealing plate 1206, which causes the sealing column 1204 to move downward due to the water pressure, and the water enters the interior of the dropper cup 8 through the water outlet channel 1203 again, replenishing the dropper cup 8 with water, thereby achieving the effect of keeping the dropper cup 8 full of water. This process does not require other power to provide control, and only needs to keep the water inside the water tank 1. The water inside the dropper cup 8 flows into the drip pipe 13. Since the drip pipe 13 is equipped with a water-absorbing cloth 10, the water can be kept flowing into the soil, and the soil can be effectively prevented from entering the drip pipe 13 to cause the drip pipe 13 to be blocked; When it is necessary to irrigate the soil for salt removal, firstly, water is continuously pumped from the water tank 1 through the water pump 2. At this time, multiple valves 9 are closed and only one valve 9 is left open. At this time, the water pressure in the shunt pipe 6 is high. Due to the high water pressure inside the shunt pipe 6, it cannot flow out from the dropper cup 8. The water level in the dropper cup 8 is full. At this time, the water pressure drives the piston column 1101 to move in the direction of the annular spray pipe 7. The piston column 1101 moves along the direction of the connecting column 1103, squeezing the compression spring 1102. The piston column 1101 no longer blocks the water inlet channel of the annular spray pipe 7. Water can enter the interior of the annular spray pipe 7 and irrigate the apricot trees through the sprinkler head 71. The annular spray pipe 7 is an annular circular tube, which can wrap the apricot tree in the center of the annular spray pipe 7. The water spray heads 71 ​​are distributed in an annular manner, which can dissolve and dilute the salt around the apricot tree and carry it away through the water flow. The support seat 72 is a placement rack. When placed, the support seat 72 is usually placed in contact with the ground, which can effectively prevent the annular spray pipe 7 from tilting and avoid the water spray head 71 from directly contacting the ground, resulting in a decrease in the water spraying effect. When one section of irrigation is completed, open the next valve 9 and then close the previous valve 9, leaving only one valve 9 for irrigation. In this way, the soil can be effectively irrigated and the use time is long. There is no need to lay water pipes every time irrigation is carried out, and the operation is convenient without affecting irrigation.
