Description

Technical fields:

[0001] This utility model belongs to the technical field of agricultural irrigation devices, and specifically refers to a drip irrigation device for agricultural irrigation. Background technology:

[0002] In agricultural production, the rational application of pesticides is crucial for the prevention and control of pests and diseases and for ensuring yield and quality. Traditional pesticide application requires manual hand-held sprayers to apply pesticides to the land, which is inefficient. In order to improve the efficiency of pesticide application, some agricultural production uses irrigation systems for pesticide application. During the application process, fertilizers and pesticides are often mixed together, which can easily lead to chemical precipitation. As the usage time increases, the drip emitters are prone to clogging, which needs to be improved. Summary of the Invention:

[0003] The purpose of this invention is to provide a drip irrigation device for agricultural irrigation to solve the technical problems mentioned in the background section.

[0004] This utility model is implemented as follows:

[0005] An agricultural irrigation dripping device includes a water pipe, several storage tanks connected to the water pipe, and several drippers mounted on the water pipe. Each dripper has a liquid outlet. The storage tanks store water-fertilizer or fertilizer-pesticide mixtures. A filter plate is provided between the drippers and the water pipe. The filter plate is inclined away from the water pipe and close to the inner wall of the dripper. The lower end of the filter plate is joined to the inner wall of the dripper to form a sedimentation chamber. An adsorption wheel is rotatably connected inside the sedimentation chamber. The surface of the adsorption wheel has a sedimentation port for accommodating impurities. The adsorption wheel protrudes from the filter plate at the end away from the sedimentation chamber. The portion of the adsorption wheel protruding from the sedimentation chamber is located on one side of the rotation axis of the adsorption wheel. The rotation of the adsorption wheel causes impurities above the filter plate to enter the sedimentation chamber.

[0006] By adopting the above technical solution, fertilizers or liquid fertilizers entering the dripper are filtered through a tilted filter plate. As time goes by, some impurities settle on the top of the filter plate and fall into the sedimentation port. As the weight in the sedimentation port increases, it drives the adsorption wheel to rotate, carrying the impurities accumulated on the top of the filter plate into the sedimentation chamber. This allows the sedimentation port located below the filter plate to enter the top of the filter plate, facilitating automatic filtration and collection of impurities. This helps reduce the clogging of the dripper caused by the accumulation of impurities.

[0007] Preferably, the filter plate has an opening, and the adsorption wheel protrudes from the surface of the filter plate through the opening. The opening is located on the side of the filter plate away from the water pipe.

[0008] By adopting the above technical solution, due to the tilt of the filter plate, the impurities that settle on the upper surface of the filter plate accumulate towards the opening, which is conducive to the accumulation of impurities at the sedimentation port and helps to improve the speed of impurity collection.

[0009] Preferably, the filter plate is located below the water pipe.

[0010] By adopting the above technical solution, impurities are made to accumulate in the direction closer to the opening.

[0011] Preferably, the inner wall of the sedimentation port is provided with an anti-stick coating.

[0012] By adopting the above technical solution and setting an anti-stick coating on the inner wall of the sedimentation port, it is beneficial for impurities to detach from the sedimentation port after entering the sedimentation chamber.

[0013] Preferably, the adsorption wheel includes a wheel body and a rotating shaft rotatably connected to the wheel body, there is a movement gap between the wheel body and the rotating shaft, the wheel body is hollow, and the wheel body can float in water, fertilizer or fertilizer and pesticide.

[0014] By adopting the above technical solution, the wheel floats under the action of buoyancy, the axle limits the wheel, and a clearance is left between the wheel and the axle, which helps to reduce the friction force that the wheel has to overcome when it rotates.

[0015] Preferably, the dripper includes a pressure compensation component, a pipe wall, and two baffles. The liquid outlet is located on the pipe wall. The filter plate and the pressure compensation component are both located on the pipe wall. The pressure compensation component is used to maintain stable liquid output. The sedimentation chamber is formed by splicing the baffles, the pipe wall, and the filter plate. The pipe wall has interconnected filtration spaces and flow adjustment spaces. The sedimentation chamber is connected to the filtration spaces through a filter port on the filter plate. A sedimentation box is slidably connected inside the sedimentation chamber. The sedimentation box moves into the sedimentation chamber to a retracted state and moves away from the sedimentation chamber to an open state.

[0016] By adopting the above technical solution, the sedimentation box can be moved, enabling staff to clean the impurities inside the sedimentation box.

[0017] Preferably, the sedimentation box is provided with an activated carbon layer for adsorbing impurities.

[0018] By adopting the above technical solution, when impurities enter the installation cavity, they are adsorbed by the activated carbon layer, reducing the amount of impurities floating into the sedimentation port and causing the adsorption wheel to rotate and re-enter the filter plate.

[0019] Preferably, the sliding directions of the plurality of sedimentation boxes are parallel and they move toward the same side of the tube wall away from the sedimentation chamber. A connecting rod is provided at the end of each sedimentation box away from the sedimentation chamber, and the connecting rod is fixed to the plurality of sedimentation boxes.

[0020] By adopting the above technical solution, it is easy to move and open the two sedimentation boxes at the same time.

[0021] The outstanding advantages of this utility model compared to the prior art are:

[0022] 1. This utility model uses an inclined filter plate to filter fertilizers or liquid fertilizers. Some impurities fall into the sedimentation port, which drives the adsorption wheel to rotate, so that the sedimentation port located below the filter plate enters the upper part of the filter plate, which facilitates the automatic filtration and collection of impurities, and helps to reduce the clogging of the drip head due to the accumulation of impurities.

[0023] 2. This utility model provides an anti-stick coating on the inner wall of the sedimentation port, which helps impurities to detach from the sedimentation port after entering the sedimentation chamber;

[0024] 3. The wheel body of this utility model floats under the action of buoyancy, and the rotating shaft limits the wheel body, leaving a clearance between the wheel body and the rotating shaft, which helps to reduce the friction force that the wheel body has to overcome when rotating.

[0032] The present invention will be further described below with reference to specific embodiments:

[0033] This application discloses a drip irrigation device for agricultural irrigation, see [link to relevant documentation]. Figure 1 It includes a water pipe 3, a storage tank 2 and several drippers 1. The storage tank 2 is used to store water-fertilizer or fertilizer and pesticide (hereinafter referred to as liquid fertilizer). The water pipe 3 connects to several storage tanks 2. The storage tanks 2 are used to transport the liquid fertilizer to the drippers 1. The drippers 1 are fixedly connected to the water pipe 3. Several drippers 1 are distributed at intervals along the length of the water pipe 3. A control valve 4 is connected between the drippers 1 and the water pipe 3 to control the opening and closing of the drippers 1 and the water pipe 3.

[0034] See Figure 1 and Figure 2 The dripper 1 includes a pipe wall 11, a pressure compensation component 12, and two baffles 13. The two ends of the control valve 4 are threadedly connected to the water pipe 3 and the pipe wall 11, respectively. The pipe wall 11 is located below the water pipe 3. The pipe wall 11 contains a filtration space 111 and a flow regulation space 112, which are connected. The filtration space 111 and the inner cavity of the water pipe 3 are vertically distributed, while the filtration space 111 and the flow regulation space 112 are horizontally distributed. An outlet 113 is provided on the pipe wall 11, located on the side of the flow regulation space 112 away from the filtration space 111 and connected to the flow regulation space 112. The medicine flowing from the water pipe 3 passes through the filtration space 111 and the flow regulation space 112 sequentially before dripping from the dripper 1 through the outlet 113. The pressure compensation component 12 is a flow compensation valve 121, used to control the stability of the liquid output from the outlet 113, thereby maintaining a stable dripping of the medicine. The flow compensation valve 121 can adjust the size of the liquid flow channel when the hydraulic pressure changes by means of elastic diaphragm, spring valve, etc., to achieve stable liquid output.

[0035] The partition 13 is located in the filter space 111. The two partitions 13 are symmetrically arranged with respect to the center line of the filter space 111. The two partitions 13 are distributed horizontally, and the cross section of the partition 13 in the vertical direction is L-shaped.

[0036] See Figure 2and Figure 3 A filter plate 5 is fixed inside the pipe wall 11. The filter plate 5 is located within the filtration space 111, between the flow compensation valve 121 and the water pipe 3. The filter plate 5 includes a first filter section 51, a second filter section 52, and a connecting section 53. Filter holes are spaced apart on the first filter section 51, the second filter section 52, and the connecting section 53. The first filter section 51 and the second filter section 52 are symmetrically arranged with respect to the centerline of the filtration space 111. The cross-sections of the first filter section 51 and the second filter section 52 are inclined in the vertical direction. 52 is inclined towards the inner wall of the pipe wall 11 in a direction away from the water pipe 3. The horizontal distance between filter section 1 51 and filter section 2 52 gradually increases in the direction away from the water pipe 3. The connecting part 53 is located between filter section 1 51 and filter section 2 52, and is located above filter section 1 51 and filter section 2 52. The connecting part 53 is integrally formed and fixed with filter section 1 51 and filter section 2 52. The vertical section of the connecting part 53 is convex upward in an arc shape. The end of filter section 1 51 and filter section 2 52 away from the connecting part 53 is fixed to the pipe wall 11. Filter section 1 51 and filter section 2 52 are respectively located above two partitions 13. The upper end of the partition 13 is fixedly connected to the corresponding filter section 1 51 or filter section 2 52. The partition 13, filter plate 5 and pipe wall 11 are spliced ​​to form two sedimentation chambers 64. The two sedimentation chambers 64 are arranged at intervals and are connected to the filter space 111 through the filter port of filter plate 5.

[0037] See Figure 2 and Figure 3 The pipe wall 11 has installation ports 114, the position and number of which correspond one-to-one with the position and number of sedimentation chambers 64. The distribution direction of the installation ports 114 and the corresponding sedimentation chambers 64 is parallel to the distribution direction of the two sedimentation chambers 64. The installation ports 114 are located on the same side of the corresponding sedimentation chambers 64 and are connected to the corresponding sedimentation chambers 64. A sedimentation box 6 is slidably connected inside the sedimentation chamber 64. The sedimentation box 6 is slidably connected to the pipe wall 11 and enters the sedimentation chamber 64 through the installation port 114. A sealing ring 61 is fixed on the sedimentation box 6 to seal the gap between the inner wall of the installation port 114 and the corresponding sedimentation box 6 after it is inserted into the sedimentation chamber 64. The sliding direction of the sedimentation box 6 is parallel to the distribution direction between the installation port 114 and the corresponding sedimentation chamber 64.

[0038] See Figure 3 and Figure 4An activated carbon layer 62 is laid inside the sedimentation box 6. The activated carbon layer 62 is used to adsorb impurities entering the sedimentation chamber 64. The sedimentation box 6 extends out of the pipe wall 11 to replace the activated carbon layer 62. When the sedimentation box 6 moves closer to the sedimentation chamber 64 to the retracted state, the sealing ring 61 seals the gap between the installation port 114 and the sedimentation box 6. The sealing ring 61 is a rubber ring. When the sedimentation box 6 moves away from the sedimentation chamber 64 to the open state, it is convenient for the staff to clean the impurities settled in the sedimentation box 6.

[0039] See Figure 3 and Figure 4 A connecting rod 63 is fixed on the sedimentation box 6. The connecting rod 63 is located on the same side of the two sedimentation boxes 6. The connecting rod 63 is fixedly connected to the two sedimentation boxes 6. The connecting rod 63 is located on the side of the sedimentation box 6 away from the sedimentation chamber 64. The connecting rod 63 facilitates the simultaneous movement of the two sedimentation boxes 6.

[0040] See Figure 3 and Figure 4 An opening 54 is provided on either filter section 1 51 or filter section 2 52. The opening 54 is located at the end of filter section 1 51 or filter section 2 52 that is away from the water pipe 3. An adsorption wheel 7 is rotatably connected in both sedimentation chambers 64. The rotation axis of the adsorption wheel 7 is horizontal and perpendicular to the distribution direction of the two sedimentation chambers 64. The adsorption wheel 7 is rotatably connected to the filter plate 5.

[0041] See Figure 3 and Figure 5 The adsorption wheel 7 includes a rotating shaft 71 and a wheel body 72, which are rotatably connected. There is a clearance 73 between the wheel body 72 and the rotating shaft 71, allowing the wheel body 72 to move up and down relative to the rotating shaft 71. The rotating shaft 71 is located below the corresponding filter section 1 51 or filter section 2 52. The wheel body 72 protrudes through the opening 54 and protrudes from the upper end face of the corresponding filter section 1 51 or filter section 2 52. The inner wall of the opening 54 is attached to the surface of the wheel body 72. The part of the wheel body 72 that protrudes from the filter plate 5 is located on the side away from the other wheel body 72 along the axis of rotation. Several sedimentation ports 721 are opened on the surface of the wheel body 72, allowing impurities to enter.

[0042] See Figure 3 and Figure 6 An anti-stick coating 722 is sprayed onto the inner wall of the sedimentation port 721. The anti-stick coating 722 is made of PTFE or silicone. Each sedimentation port 721 can hold 0.5-1g of impurities. As impurities accumulate in the sedimentation port 721 protruding from the filter plate 5, the wheel 72 rotates to transport the impurities into the sedimentation chamber 64. The sedimentation port 721 located below the filter plate 5 moves to above the filter plate 5, which facilitates the transport of impurities above the filter plate 5 to the sedimentation chamber 64. The impurities are then adsorbed by the activated carbon layer 62, reducing the amount of impurities that re-enter the sedimentation chamber 64 and then above the filter plate 5.

[0043] See Figure 3 and Figure 6 The wheel body 72 is made of PVC or hard plastic and has a hollow structure. When the control valve 4 is opened, the medicine enters the sedimentation chamber 64 through the filter port on the filter plate 5, causing the wheel body 72 to float and reducing the friction between the wheel body 72 and the shaft 71.

[0044] The implementation principle of this application embodiment is as follows: When irrigating crops, the fertilizer or liquid fertilizer in the storage tank 2 enters the filtration space 111 through the water pipe 3, is filtered, enters the flow regulation space 112, and then flows out from the outlet 113. As the usage time increases, most of the impurities deposited at the upper end of the first filter section 51 or the second filter section 52 accumulate near the opening 54 and the wheel 72 that passes through the opening 54 under the action of gravity and the impact force of the liquid. The impurities fall into the sedimentation port 721. The weight of the impurities in the sedimentation port 721 drives the wheel 72 to rotate, gradually transferring the impurities above the filter plate 5 to the sedimentation chamber 64, making the filter plate 5 less prone to clogging. This helps to reduce the clogging of the dripper 1 due to long-term accumulation of impurities. The staff can periodically remove the sedimentation box 6 to replace the activated carbon adsorption layer.

[0045] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
