Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, specifically to a soil amendment dispensing device for soil remediation. Background Technology

[0002] Soil conditioners can improve the physical, chemical, or biological properties of soil and promote plant growth. They are used for soil remediation. Depending on the type of soil conditioner, the application method varies. Some conditioners are directly applied to the soil, while others need to be dissolved before spraying. However, current application devices for soil conditioners have certain shortcomings. The spray range cannot be easily adjusted, meaning that different soils have different needs for conditioners. Some soils require more conditioner, while others require less. The distance between the nozzles on the application device cannot be adjusted, making it impossible to adjust the amount of conditioner applied according to the soil's needs. Furthermore, the nozzles are prone to clogging, and the inability to easily install and remove the nozzles results in low maintenance efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a soil amendment dispensing device for soil remediation, so as to solve the problems mentioned in the background art, such as the inability to adjust the dispensing range and the inconvenience of installing and removing the nozzle.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A soil amendment dispensing device for soil remediation includes: a dispensing vehicle, on which an agent tank is fixedly installed, and the agent tank is connected to a pump body; The first dispensing spray assembly is installed on the dispensing vehicle and is connected to the pump body, through which the modifier is delivered. The second dispensing spray assembly is movably mounted on the first dispensing spray assembly, and the spray range is adjusted when the second dispensing spray assembly moves. A convenient adjustment component is provided, which is connected to the second dispensing and spraying component and drives the second dispensing and spraying component to move.

[0005] Preferably, the first dispensing and spraying assembly includes: a drug delivery pipe, which is fixedly installed on the dispensing vehicle and connected to the pump body; The first nozzle is installed on the drug delivery tube.

[0006] Preferably, the second dispensing and spraying assembly includes: two movable adjusting tubes, which are respectively installed at both ends of the drug delivery tube; The second nozzle is mounted on the movable regulating pipe.

[0007] Preferably, the movable adjustment tube moves on the drug delivery tube to adjust the distance between the first nozzle and the second nozzle.

[0008] Preferably, the convenient adjustment component includes: an adjustment support plate, which is movably connected to a movable adjustment tube to drive the movable adjustment tube to move; An adjusting screw is mounted on an adjusting support plate.

[0009] Preferably, the adjusting screw drives the adjusting bearing plate to move up and down when it rotates.

[0010] Preferably, the convenient adjustment component further includes: a loading drive ring, which is movably mounted on the drug delivery tube; The matching support rod is movably mounted on the load-balanced drive ring; The load-balanced plate is movably connected to the load-balanced drive ring, which drives the load-balanced plate to move.

[0011] Preferably, the load-balanced drive ring is connected to the movable adjustment pipe, and the movable adjustment pipe drives the load-balanced drive ring to move, thereby locking the second nozzle by cooperating with the bearing rod.

[0012] Preferably, one load-balanced drive ring is movably connected to two load-balanced strips, which are located on the upper and lower sides of the load-balanced drive ring, respectively.

[0013] Preferably, the loading strip cooperates with the first nozzle to fix the first nozzle on the drug delivery pipe.

[0014] Compared with the prior art, the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. The application vehicle is equipped with a first nozzle and a second nozzle. The distance between the first and second nozzles can be adjusted according to soil requirements. When the soil requires more amendment, the distance between the first and second nozzles is adjusted to the minimum value, which allows for more concentrated application of the amendment and meets the needs of the larger amount. When the soil requires less amendment, the first nozzle can be moved to increase the distance between it and the second nozzle. This not only increases the spray range and improves the efficiency of amendment application, but also makes the amendment spray more dispersed, meeting the needs of the smaller amount of amendment required. It is very convenient to use.

[0015] 2. When maintenance of the first and second nozzles is required, adjust the first nozzle to maximize the distance between it and the second nozzle. This will unlock both the first and second nozzles, allowing for quick disassembly and easy maintenance.

[0016] 3. When installing the first and second nozzles, insert the first nozzle into the assembly connecting pipe and position the second nozzle onto the moving adjusting pipe. Then, rotate the adjusting screw to move the adjusting bearing plate upward, which will drive the load-bearing drive ring to move. Under the action of the load-bearing drive ring, the second nozzle can be locked. As the load-bearing drive ring moves, it will drive the load-bearing strip to move, which in turn locks the first nozzle under the action of the load-bearing strip. This completes the fixed installation of the first and second nozzles. The operation is simple, convenient and quick. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention provides a technical solution: like Figure 1 and Figure 2As shown, a soil amendment dispensing device for soil remediation includes: a dispensing vehicle 1, a first dispensing spray assembly, a second dispensing spray assembly, and a convenient adjustment assembly. A reagent tank 11 is bolted to the dispensing vehicle 1. The reagent tank 11 is connected to a pump body 12 via a pipe. The pump body 12 extracts the amendment from the reagent tank 11 and is fixedly mounted on the dispensing vehicle 1 with screws. The first dispensing spray assembly is mounted on the dispensing vehicle 1 and connected to the pump body 12, which delivers the amendment to it. The second dispensing spray assembly is movably mounted on the first dispensing spray assembly, and its spray range can be adjusted during movement. The amount of amendment dispensed can be adjusted by adjusting the spray range.

[0030] When the spraying range is small, the soil amendment is sprayed more concentratedly, which can meet the needs of soils that require more amendment. When the spraying range is large, the soil amendment is sprayed more dispersedly, which can meet the needs of soils that require less amendment. In addition, the convenient adjustment component is connected to the second dispensing component and drives the second dispensing component to move, thereby completing the adjustment of the spraying range.

[0031] like Figure 2 and Figure 6 As shown, the first delivery spray assembly includes a drug delivery pipe 2 and a first nozzle 3. The lower end of the drug delivery pipe 2 is welded and fixed with a mounting frame 20. The drug delivery pipe 2 is installed on the delivery vehicle 1 through the mounting frame 20. The mounting frame 20 can be fixed to the delivery vehicle 1 by bolts. A connecting pipe 21 is integrally formed on the drug delivery pipe 2. The connecting pipe 21 is connected to the pump body 12. The connecting pipe 21 and the pump body 12 can be connected by a flange to realize the delivery of the modifier.

[0032] Assembly connecting pipes 23 are symmetrically welded and fixed on the drug delivery pipe 2. A protruding mating plate 24 is integrally formed on the assembly connecting pipe 23, and the surface of the protruding mating plate 24 is smooth and burr-free. Figure 10 As shown, a first nozzle 31 is welded and fixed on the first nozzle 3. A fitting ring plate 32 is integrally formed on the first nozzle 31, and the surface of the fitting ring plate 32 is smooth and burr-free. The first nozzle 3 is installed on the drug delivery pipe 2 through the first nozzle 31. During installation, the first nozzle 31 on the first nozzle 3 is inserted into the assembly connecting pipe 23, so that the fitting ring plate 32 on the first nozzle 31 contacts the protruding mating plate 24 on the assembly connecting pipe 23.

[0033] like Figure 4 and Figure 6As shown, the second dispensing spray assembly includes: a movable regulating pipe 4 and a second nozzle 5. There are two movable regulating pipes 4, which are respectively installed at both ends of the drug delivery pipe 2. Specifically, movable cavities 22 are opened at both ends of the drug delivery pipe 2, and the movable regulating pipe 4 is inserted into the movable cavities 22 to ensure the sealing between the movable regulating pipe 4 and the drug delivery pipe 2.

[0034] like Figure 7 and Figure 8 As shown, a second nozzle 51 is welded and fixed to the second nozzle 5. A connecting sleeve 52 is integrally formed on the end of the second nozzle 51 away from the second nozzle 5. A connecting ring cavity 53 is formed on the connecting sleeve 52, and a locking guide plate 54 is integrally formed on the connecting sleeve 52. A locking insertion hole 55 is formed on the locking guide plate 54. In order to stably install the second nozzle 5 on the movable adjustment pipe 4, a support plate 41 is welded and fixed to the movable adjustment pipe 4. A sealing connecting sleeve 42 is welded and fixed to the support plate 41. When installing the second nozzle 5, the sealing connecting sleeve 42 is inserted into the connecting ring cavity 53 on the connecting sleeve 52. In this way, the movable adjustment can be achieved with the cooperation of the sealing connecting sleeve 42 and the connecting ring cavity 53. The pipe 4 and the second nozzle 5 are sealed, and the connecting pipe sleeve 52 is in contact with the support plate 41. In addition, an extension guide plate 43 is integrally formed on the support plate 41. A guide channel 44 is opened on the extension guide plate 43, and a support connecting plate 45 is integrally formed on the extension guide plate 43. A support connecting hole 46 is opened on the support connecting plate 45. When installing the second nozzle 5, the locking guide plate 54 on the second nozzle 5 is aligned with the guide channel 44, so that the locking guide plate 54 is inserted into the guide channel 44 to guide the second nozzle 5 and ensure its installation accuracy. When the support plate 41 is in contact with the connecting pipe sleeve 52, the support connecting hole 46 is aligned with the locking insertion hole 55 on the locking guide plate 54.

[0035] The movable regulating tube 4 can move along the movable tube cavity 22 on the drug delivery tube 2. As the movable regulating tube 4 moves, it can drive the second nozzle 5 to move synchronously, thereby realizing the distance adjustment between the first nozzle 3 and the second nozzle 5. The surface of the movable regulating tube 4 is smooth and burr-free, and the inner wall of the movable tube cavity 22 is smooth and burr-free.

[0036] like Figure 2 , Figure 3 and Figure 7As shown, the convenient adjustment assembly includes: an adjustment support plate 6 and an adjustment screw 63. The adjustment screw 63 is mounted on the adjustment support plate 6, and moves the adjustment support plate 6 by means of the adjustment screw 63. Specifically, a threaded through hole 62 is provided at one end of the adjustment support plate 6, and the threaded through hole 62 is threadedly engaged with the adjustment screw 63. An assembly hole 13 is provided on one side of the delivery vehicle 1. In order to enable the adjustment screw 63 to move the adjustment support plate 6 when rotating, a mating bearing 64 is sleeved on the lower end of the adjustment screw 63 and installed in the assembly hole 13. This allows the adjustment screw 63 to rotate without moving up and down. A limiting guide rod 14 is welded and fixed on the other side of the delivery vehicle 1. A limiting fitting hole 61 is provided, into which a limiting guide rod 14 is inserted. The interaction between the limiting guide rod 14 and the limiting fitting hole 61 restricts the adjustment bearing plate 6, preventing it from rotating. When the adjusting screw 63 rotates, the screw thread causes the adjustment bearing plate 6 to move up and down. Additionally, symmetrically integrally formed adjusting links 65 are provided at both ends of the adjustment bearing plate 6. Adjusting links 66 are hinged to the adjusting links 65, and the lower end of the adjusting links 66 is hinged to the moving adjusting tube 4. Thus, when the adjustment bearing plate 6 moves up and down, the adjusting links 66 drive the moving adjusting tube 4 to move, thereby adjusting the distance between the first nozzle 3 and the second nozzle 5, and adjusting the spray range.

[0037] like Figure 4 and Figure 6 As shown, the convenient adjustment component also includes: a loading drive ring 7, a cooperating support rod 76, and a loading strip 8. The loading drive ring 7 is movably installed on the drug delivery tube 2. Specifically, a support block 71 is integrally formed on one side of the loading drive ring 7. A support channel 72 is opened on the support block 71. A first support rod 25 is symmetrically welded and fixed at the upper and lower ends of the assembly tube 23. A bent plate carrier 26 is welded and fixed on the first support rod 25. A second support rod 27 is welded and fixed on the bent plate carrier 26. The second support rod 27 is inserted into the support channel 72 on the support block 71. The loading drive ring 7 is supported by the cooperation between the second support rod 27 and the support channel 72, so that the loading drive ring 7 can move along the second support rod 27.

[0038] like Figure 9 As shown, a load-matching connecting strip 73 is integrally formed on the other side of the load-matching drive ring 7. A connecting cavity 75 is opened on the load-matching connecting strip 73. A mating bearing rod 76 is inserted into the connecting cavity 75. The mating bearing rod 76 is supported by the connecting cavity 75, and the mating bearing rod 76 can move along the connecting cavity 75.

[0039] like Figure 4and Figure 10 As shown, the loading strip 8 is movably connected to the loading drive ring 7. The loading drive ring 7 drives the loading strip 8 to move. A support mating hole 81 is provided on the loading strip 8, which mates with the first support rod 25. The mating of the support mating hole 81 and the first support rod 25 limits the movement of the loading strip 8, allowing it to move only up and down along the first support rod 25. A connecting hinge frame 82 is integrally formed on the loading strip 8, and a connecting rod 79 is hinged to the connecting hinge frame 82. The other end of the rod 79 is hinged to the load-balanced drive ring 7. In addition, two load-balanced strips 8 are movably connected to one load-balanced drive ring 7, located on the upper and lower sides of the load-balanced drive ring 7 respectively. Specifically, the lower end of the connecting rod 79 hinged to the upper end of the load-balanced drive ring 7 is hinged to the upper end of the load-balanced drive ring 7, and the upper end of the connecting rod 79 hinged to the lower end of the load-balanced drive ring 7 is hinged to the lower end of the load-balanced drive ring 7. In this way, when the load-balanced drive ring 7 moves, it can drive the two load-balanced strips 8 to move.

[0040] like Figure 8 and Figure 9 As shown, the load-balanced drive ring 7 is connected to the moving adjustment pipe 4. The moving adjustment pipe 4 drives the load-balanced drive ring 7 to move. Specifically, a connecting link frame 47 is welded and fixed to the lower end of the moving adjustment pipe 4. A connecting channel 48 is provided on the connecting link frame 47, and a drive part 49 is integrally formed on the connecting link frame 47. A drive channel 491 is provided on the drive part 49, and the drive channel 491 communicates with the connecting channel 48. The widths of the drive channel 491 and the connecting channel 48 are equal. The inner walls of channel 491 and connecting channel 48 are smooth and burr-free. A linkage rod 74 is welded and fixed to the lower end of the load-bearing connecting strip 73. The linkage rod 74 is inserted into the connecting channel 48 and contacts the inner wall of the connecting channel 48. The surface of the linkage rod 74 is smooth and burr-free. When the moving adjusting tube 4 moves, the linkage rod 74 is in the driving channel 491. With the cooperation of the driving channel 491 and the linkage rod 74, the load-bearing driving ring 7 can be moved.

[0041] A movable support block 77 is welded and fixed to the support support rod 76, and a locking support rod 78 is welded and fixed to the movable support block 77. The locking support rod 78 is inserted into the support connection hole 46. In this way, when the moving adjustment tube 4 moves along the moving tube cavity 22, the locking support rod 78 and the support connection hole 46 can drive the support support rod 76 to move along the connection cavity 75. When the locking support rod 78 is inserted into the locking insertion hole 55, the second nozzle 5 can be fixed on the moving adjustment tube 4, thereby realizing the locking of the second nozzle 5 by the support support rod 76.

[0042] like Figure 5 and Figure 10 As shown, the loading strip 8 cooperates with the first nozzle 3 to fix the first nozzle 3 onto the drug delivery pipe 2. Specifically, a locking block 83 is welded and fixed to the loading strip 8, and a locking slot 84 is provided on the locking block 83. A first annular groove 85 and a second annular groove 86 are respectively provided at both ends of the locking slot 84. After the first nozzle 31 on the first nozzle 3 is inserted into the assembly connecting pipe 23, the protruding fitting plate 24 contacts the fitting ring plate 32. Thus, when the loading drive ring 7 drives the two loading strips 8 connected to it to move towards each other, the protruding fitting plate 24 will contact the fitting ring plate. The 32 is inserted into the locking slot 84 on the mating locking block 83. Under the action of the locking slot 84, the protruding mating plate 24 and the mating ring plate 32 can be locked together, thereby fixing the first nozzle 3 on the drug delivery tube 2. At this time, the first ring groove 85 will contact the first nozzle 31, and the second ring groove 86 will contact the assembly connecting pipe 23. The two mating locking blocks 83 connected by the load driving ring 7 are closed together. Under the action of the mating locking block 83, the connection between the first nozzle 3 and the assembly connecting pipe 23 can be further sealed to ensure that there is no leakage.

[0043] When applying the soil amendment, the pump 12 draws the amendment from the agent tank 11 into the delivery pipe 2, and then sprays it through the first nozzle 3 and the second nozzle 5. In actual use, when the adjusting support plate 6 is not moving downwards, the distance between the first nozzle 3 and the second nozzle 5 is at its minimum, resulting in the smallest spray range. Because the distance between the first nozzle 3 and the second nozzle 5 is minimal, the amendment spray is most concentrated, suitable for soils requiring a larger amount of amendment. When the distance between the first nozzle 3 and the second nozzle 5 increases, the movement of the first nozzle 3 will increase the spray range of the amendment, and also increase the spray range of the amendment. The spray is more dispersed, thus reducing the amount of amendment applied to the same soil, making it suitable for soils requiring less amendment. Furthermore, the larger spray range increases the area of ​​amendment sprayed simultaneously, improving the efficiency of amendment application. Specifically, when adjusting the distance between the first nozzle 3 and the second nozzle 5, rotating the adjusting screw 63 causes the adjusting support plate 6 to move downwards under the action of the thread. As the adjusting support plate 6 moves downwards, the adjusting connecting rod 66 causes the two movable adjusting pipes 4 on the delivery pipe 2 to move in opposite directions, thereby causing the second nozzles 5 at both ends of the delivery pipe 2 to move in opposite directions, thus completing the distance adjustment between the first nozzle 3 and the second nozzle 5. This is very convenient. When the moving adjusting tube 4 moves, the locking rod 78 is inserted into the support connection hole 46. Therefore, as the moving adjusting tube 4 moves, the supporting bearing rod 76 will also move synchronously with it. Furthermore, the supporting bearing rod 76 will not separate from the connection cavity 75. When it is necessary to disassemble the first nozzle 3 and the second nozzle 5, rotating the adjusting screw 63 causes the adjusting bearing plate 6 to move downwards, driving the moving adjusting tube 4 to move. This allows the linkage rod 74 to enter the drive channel 491. Thus, as the moving adjusting tube 4 moves, under the action of the drive channel 491, the linkage rod 74 will move away from the moving adjusting tube 4, thereby driving the loading drive ring 7 away from the drug delivery tube 2. As the loading drive ring 7 moves, it also drives the mating support rod 76 to move synchronously. The movement of the mating support rod 76 causes the locking mating rod 78 on the mating support rod 76 to disengage from the locking insertion hole 55 on the locking guide plate 54. However, the locking mating rod 78 will not separate from the support connection hole 46, thus allowing the second nozzle 5 to be in an unlocked state, enabling it to be quickly removed for necessary maintenance. As the loading drive ring 7 moves away from the drug delivery tube 2, the connecting rod 79 pushes the loading strip 8 connected to the loading drive ring 7 to move in opposite directions; that is, the loading strip 8 above the loading drive ring 7 moves upward, and the loading strip 8 below the loading drive ring 7 moves downward.This allows the protruding mating plate 24 and the fitting ring plate 32 to separate from the locking slot 84 on the mating locking block 83, thus unlocking the first nozzle 3. This allows for quick and easy disassembly of the first nozzle 3 for necessary maintenance, making it very convenient. It also facilitates the easy disassembly of the first nozzle 3 and the second nozzle 5. Installation of the first nozzle 3 and the second nozzle 5 is also very convenient. The first nozzle pipe 31 on the first nozzle 3 is inserted into the assembly connecting pipe 23, causing the protruding mating plate 24 to contact the fitting ring plate 32, thus positioning the first nozzle 3. Then, the connecting ring cavity 53 on the second nozzle 5 is connected to the locking slot 84 on the support plate 41. The sealing sleeve 42 is engaged with the locking guide plate 54, which is then inserted into the guide channel 44 to position the second nozzle 5. Then, rotating the adjusting screw 63 moves the adjusting support plate 6 upwards. As the adjusting support plate 6 moves upwards, the locking fitting rod 78 is inserted into the locking insertion hole 55 to fix the second nozzle 5. Simultaneously, under the action of the load-bearing drive ring 7, the two load-bearing strips 8 connected to it move towards each other, causing the locking block 83 to close together. This also allows the protruding fitting plate 24 and the fitting ring plate 32 to be inserted into the locking slot 84 on the locking block 83, thus fixing the first nozzle 3. This process is very convenient, quick, and simple to operate.
