Description

TECHNICAL FIELD

[0001] The application relates to the technical field of agricultural engineering, in particular to an agricultural water-saving drip irrigation device. BACKGROUND

[0002] In the field of agricultural production, efficient use of water resources has been a key problem restricting sustainable development. Traditional irrigation methods such as flooding irrigation and sprinkling irrigation have the obvious defects of low water resource utilization rate (usually less than 50%), easy soil compaction and nutrient loss, and inability to accurately match the water demand of crops in different growth periods. In particular, in arid and semiarid areas, the contradiction between water shortage and low irrigation efficiency is more prominent. In the use of the device, first, the water inlet is inserted into the water conveying pipe, and the water flow is extruded by the protrusions and rubber sheets in the device, so that the water flow is slowed down when entering the water inlet through the water conveying groove, and then drips from the water outlet of the device. Since the rubber sheet is relatively small, the water temperature of the water flow will affect the elasticity of the rubber sheet when the device is used for drip irrigation in cold or hot environments, causing uneven water flow from the water inlet to the outside due to the elastic deformation of the rubber sheet when the water flow is extruded by the rubber sheet and the protrusions, thereby affecting the growth of crops and reducing the overall quality of the device during drip irrigation. SUMMARY

[0003] To solve the above technical problems, the application provides an agricultural water-saving drip irrigation device, which comprises a main body, a connecting cover screw-connected in the inside of the main body, a water conveying groove formed in the inner wall of the connecting cover, and a water outlet formed in the inside of the main body. A contraction mechanism is installed in the inside of the main body and used for contraction when the main body moves. A buffer mechanism is installed in the inside of the main body and used for reducing the impact force of water flow movement.

[0004] Further, the main body comprises: A conveying assembly is installed in the inside of the main body and used for guiding water flow movement. A sliding assembly is installed in the inside of the conveying assembly and used for sliding under the impact of water flow.

[0005] Further, the contraction mechanism comprises: A telescopic assembly is installed in the inside of the main body and used for contraction when the sliding assembly moves. A swinging assembly is fixedly installed on the inner wall of the conveying assembly and used for assisting the sliding assembly to slide.

[0006] Further, the buffer mechanism comprises: The fixed assembly is arranged in the interior of the conveying assembly, and is used for dispersing the water flow.

[0007] Further, the conveying assembly comprises a water inlet arranged in the interior of the main body, and two water distribution grooves are arranged in the side wall of the water inlet.

[0008] Further, the bottom of each water distribution groove is provided with a protrusion, and the bottom of the protrusion is provided with a rubber sheet. The top of the protrusion is fixedly connected with the inner wall of the main body, and the outer surface of the rubber sheet is fixedly connected with the inner wall of the connecting cover.

[0009] Further, the sliding assembly comprises a sliding plate slidingly connected with the inner wall of the water inlet, and a connecting groove is arranged in the interior of the sliding plate.

[0010] Further, the telescopic assembly comprises a fixed block fixedly connected with the inner wall of the water inlet, and a spring is fixedly connected with the inner wall of the fixed block. The top of the spring is fixedly connected with the bottom of the sliding plate.

[0011] Further, an auxiliary groove is arranged in the interior of the spring, and a plurality of drainage grooves are arranged on the outer surface of the auxiliary groove.

[0012] Further, the fixed assembly comprises two arc-shaped strips fixedly connected with the interior of the water distribution groove, and a plurality of arc-shaped rods are arranged on the bottom of the lower arc-shaped strip, and an inclined plate is fixedly connected with the outer surface of the arc-shaped rod.

[0013] The present application has the following advantages: 1、In the process of water flow movement, part of the water flow will be guided along the drainage groove to the outside of the spring, and in the process of water flow to the outside of the spring, it will enter the interior of the water inlet, and in this process, the water pressure will decrease when the water flow moves in the spring, thereby reducing the pushing force of the water flow on the rubber sheet when the water flow moves downward, reducing the situation that the water amount of the water outlet of the device increases due to the softening of the rubber sheet caused by heat in a relatively hot environment, thereby causing excessive irrigation of crops, ensuring the normal growth of crops, and improving the accuracy of the device when performing drip irrigation on crops.

[0014] 2、The water flow entering into the water inlet will enter into the two water distribution grooves of the water inlet side wall and be transported downward, so that the water flow is divided, and the purpose of reducing the water pressure of the water flow entering into the water inlet is achieved, the rubber sheet hardening caused by low temperature in a relatively cold environment is reduced, so that when a large water flow enters into the device for drip irrigation, the interval time of the beam flow discharged due to the rubber sheet hardening is prolonged, the drip irrigation water amount can meet the normal demand of crops, and the accuracy of the device in drip irrigation of crops is further improved.

[0015] 3、During the swinging of the swinging plate, the side wall of the swinging plate will apply a pushing force to the top of the sliding plate, and when the sliding plate is subjected to the pushing force, a pushing force will be applied to the spring at the bottom of the sliding plate, and since the bottom of the spring is fixedly connected to the inner wall of the water inlet by the fixing block, the spring will be contracted to a certain extent when the top of the spring is subjected to the pushing force, so that the purpose of assisting the sliding plate to move downward when the sliding plate is subjected to the pushing force by the swinging plate is achieved, and the overall efficiency of the device in drip irrigation of crops is improved.

[0016] 4、During the flow of the water flow in the water distribution groove, part of the water flow is blocked by the arc-shaped strip and flows to the side during the flow, so that the water flow is disturbed and the overall water pressure is reduced, and then when the water flow continues to flow, the water flow is discharged to the inside of the main body through the bottom of the water distribution groove, and the water flow is blocked by the inclined plate on the arc-shaped rod during the discharge of the water flow, so that the water flow is dispersed, the effect of the water flow dispersed in the water distribution groove on the aggregation of the water flow into the main body is enhanced, and the overall efficiency of the device in drip irrigation of crops is further improved.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0021] Please refer to Figures 1-9 As shown in the drawings, the present application is a kind of agricultural water-saving drip irrigation device, comprising a main body 1, the inside of the main body 1 is threadedly connected with a connecting cover 101, the inner wall of the connecting cover 101 is provided with a water conveying groove 102, the inside of the main body 1 is provided with a water outlet 103, further comprising: A contraction mechanism 2 is installed and arranged in the inside of the main body 1, for contraction when the main body 1 moves; A buffer mechanism 3 is installed and arranged in the inside of the main body 1, for reducing the impact force of water flow movement.

[0022] The main body 1 comprises: A conveying assembly 11 is installed and arranged in the inside of the main body 1, for guiding the movement of water flow; A sliding assembly 12 is installed and arranged in the inside of the conveying assembly 11, for sliding under the impact of water flow.

[0023] The contraction mechanism 2 comprises: The telescopic assembly 21 is arranged in the interior of the main body 1 and is used to retract when the sliding assembly 12 moves. The swing assembly 22 is fixedly arranged on the inner wall of the conveying assembly 11 and is used to assist the sliding assembly 12 to slide.

[0024] The buffering mechanism 3 comprises: The fixed assembly 31 is arranged in the interior of the conveying assembly 11 and is used to disperse the water flow.

[0025] The conveying assembly 11 comprises a water inlet 111 arranged in the interior of the main body 1, and two water distribution grooves 112 are arranged on the side wall of the water inlet 111. When the sliding plate 121 slides downward, the top of the water distribution grooves 112 on the side wall will appear on the top of the sliding plate 121, and then the water flow entering the interior of the water inlet 111 will enter the two water distribution grooves 112 on the side wall of the water inlet 111 and be conveyed downward.

[0026] The bottom of the two water distribution grooves 112 is provided with a protrusion 113, and the bottom of the protrusion 113 is provided with a rubber sheet 114. The top of the protrusion 113 is fixedly connected with the inner wall of the main body 1, and the outer surface of the rubber sheet 114 is fixedly connected with the inner wall of the connecting cover 101. When the rubber sheet 114 becomes concave, the interval between the top of the rubber sheet 114 and the protrusion 113 becomes larger, and the water flow will enter the water conveying groove 102 through the gap between the rubber sheet 114 and the protrusion 113 and be discharged outward from the interior of the connecting cover 101.

[0027] The sliding assembly 12 comprises a sliding plate 121 slidingly connected with the inner wall of the water inlet 111, and a connecting groove 122 is arranged in the interior of the sliding plate 121. When the water flow enters the interior of the water inlet 111, part of the water flow will be blocked by the sliding plate 121 and enter the interior of the connecting groove 122, and the water flow will enter the auxiliary groove 213 when passing through the connecting groove 122.

[0028] The telescopic assembly 21 comprises a fixed block 211 fixedly connected with the inner wall of the water inlet 111, and a spring 212 is fixedly connected with the inner wall of the fixed block 211. The top of the spring 212 is fixedly connected with the bottom of the sliding plate 121. When the water flow enters the interior of the water inlet 111, part of the water flow will be blocked by the sliding plate 121 and enter the interior of the connecting groove 122, and the water flow will enter the auxiliary groove 213 when passing through the connecting groove 122, because the auxiliary groove 213 is arranged in the interior of the spring 212.

[0029] The spring 212 is internally provided with an auxiliary groove 213, and the outer surface of the auxiliary groove 213 is provided with a plurality of drainage grooves 214. When the water flow continues to move in the auxiliary groove 213, part of the water flow will be guided to the outside of the spring 212 along the drainage grooves 214.

[0030] The fixing assembly 31 comprises two arc-shaped strips 311 fixedly connected in the water distribution groove 112. The bottom of the lower arc-shaped strip 311 is provided with a plurality of arc-shaped rods 312, and the outer surface of the arc-shaped rod 312 is fixedly connected with an inclined plate 313. Part of the water flow is blocked by the arc-shaped strip 311 when flowing, so as to flow to the side when flowing, thereby disturbing the water flow and reducing the overall water pressure. Then, when the water flow continues to flow, it will be discharged to the inside of the main body 1 through the bottom of the water distribution groove 112.

[0031] In use, first, the outer surface of the connecting cover 101 is connected with the inner wall of the main body 1, and then the top of the main body 1 is inserted into the inside of the water conveying pipe. Then, when the water flow in the water conveying pipe moves, it will enter the inside of the main body 1 through the water inlet 111. After the water flow enters the inside of the water inlet 111, it will continue to move. When the water pressure is small, the water flow will contact the top of the rubber sheet 114 located in the inside of the connecting cover 101, and then seep outwards through the gap between the convex block 113 and the rubber sheet 114. Then, the seeped water flow enters the inside of the water conveying groove 102. After the water flow passes through the water conveying groove 102, it will enter the inside of the water outlet 103 through the inside of the connecting cover 101, and then drip outwards along the inner wall of the water outlet 103. When the water pressure is large, the water flow will quickly pass through the water inlet 111 to impact the rubber sheet 114, so that the rubber sheet 114 becomes a concave state, and thus the bottom of the rubber sheet 114 contacts the inner wall of the connecting cover 101. When the rubber sheet 114 becomes a concave state, the interval between the top of the rubber sheet 114 and the convex block 113 becomes large. When the water flow enters the water conveying groove 102 from the inside of the connecting cover 101 and is discharged outwards, the water flow will be extruded by the rubber sheet 114 and the inner wall of the main body 1 to seep into the water outlet 103 in the form of water droplets and drip outwards, thereby completing the drip irrigation of crops.

[0032] When the water flow enters the inside of the water inlet 111, part of the water flow will be blocked by the sliding plate 121 and enter the inside of the connecting groove 122, and when the water flow passes through the connecting groove 122, it will enter the inside of the auxiliary groove 213. Since the auxiliary groove 213 is opened in the inside of the spring 212, and then when the water flow continues to move in the inside of the auxiliary groove 213, part of the water flow will be guided by the drainage groove 214 to the outside of the spring 212 during its movement. During the process of the water flow being discharged to the outside of the spring 212, it will enter the inside of the water inlet 111. During this process, the water pressure will decrease when the water flow moves in the inside of the spring 212, thereby reducing the pushing force of the water flow on the rubber sheet 114 when the water flow moves downward, reducing the situation that the water volume of the device outlet 103 increases due to the softening of the rubber sheet 114 caused by heat, thereby causing over-irrigation of crops when the device is used for drip irrigation in a hot environment, ensuring the normal growth of crops and improving the accuracy of the device when used for drip irrigation of crops.

[0033] When the water pressure of the water flow entering the inside of the water inlet 111 increases, part of the water flow will contact the top of the sliding plate 121 after entering the inside of the water inlet 111. During the continuous movement of the water flow, part of the water flow exerts a pushing force on the top of the sliding plate 121. When the sliding plate 121 is pushed by the water flow, it will slide downward by a small amount. When the sliding plate 121 slides downward, the top of the water distribution groove 112 of its side wall will appear on the top of the sliding plate 121. Then the water flow entering the inside of the water inlet 111 will enter the inside of the two water distribution grooves 112 of the side wall of the water inlet 111 and be transported downward, thereby causing the water flow to be divided, further achieving the purpose of reducing the water pressure of the water flow entering the inside of the water inlet 111, reducing the situation that the water flow entering the inside of the device for drip irrigation is delayed due to the hardening of the rubber sheet 114 caused by the low temperature in a cold environment, and making the drip irrigation water volume meet the normal needs of crops, thereby further improving the accuracy of the device when used for drip irrigation of crops.

[0034] When the water with large water pressure flows into the inside of the water inlet 111, part of the water flow will contact the swing plate 222 on the top of the sliding plate 121, and then during the continuous conveying of the water flow, part of the water flow will push the swing plate 222 to make the swing plate 222 be pushed to rotate downward around the rotating shaft 221, during the swing plate 222 swings downward, the side wall will push the top of the sliding plate 121, when the sliding plate 121 is pushed, the spring 212 at the bottom of the sliding plate 121 will be pushed, because the bottom of the spring 212 is fixed by the fixed block 211 and connected to the inner wall of the water inlet 111, when the top of the spring 212 is pushed, the spring 212 will contract to a certain extent, so as to achieve the purpose of assisting the sliding plate 121 to move downward when the sliding plate 121 is pushed by the swing plate 222, and the overall efficiency of the device when the crops are drip irrigated is improved.

[0035] After the water flow is divided into the inside of the water distribution groove 112, the water flow will flow downward along the guide of the water distribution groove 112, during the water flow flows in the water distribution groove 112, part of the water flow will flow to the side when flowing is blocked by the arc-shaped strip 311, so that the water flow is disturbed, the overall water pressure is reduced, and then when the water flow continues to flow, the water flow will be discharged into the inside of the main body 1 through the bottom of the water distribution groove 112, and when the water flow is discharged, it will be blocked by the inclined plate 313 on the arc-shaped rod 312 to be dispersed, the effect of the water flow dispersed in the water distribution groove 112 to the inside of the main body 1 is enhanced, and the overall efficiency of the device when the crops are drip irrigated is further improved.
