Technical Field

[0001] This utility model relates to the field of soil remediation spraying, and in particular to a device for uniformly spraying soil remediation agents. Background Technology

[0002] With the rapid development of industrialization and agricultural production, soil pollution has become increasingly serious. Heavy metals, pesticide residues, and organic pollutants pose a severe threat to the ecological environment and human health. Soil remediation technology, as a key link in environmental governance, focuses on reducing the concentration or toxicity of pollutants and restoring soil function through physical, chemical, or biological means. Therefore, devices used to evenly spray pesticide solutions onto contaminated soil have become crucial equipment.

[0003] While existing soil remediation spraying devices have largely achieved the function of spraying chemicals, they still have significant limitations in practical applications. First, many devices have a fixed spraying range, which cannot be flexibly adjusted according to the shape and size of the contaminated area. For contaminated areas that are narrow or irregular in shape, spraying within a fixed range will result in a large amount of chemicals being wasted in non-target areas. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a uniform spraying device for soil remediation agents, which aims to improve the problem in the prior art that "the spraying range is fixed and cannot be flexibly adapted to polluted areas of different shapes, resulting in waste of agents".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a uniform spraying device for soil remediation agents, comprising a storage tank and a trolley. The storage tank is fixedly connected to the top of the trolley, and a water supply pipe is fixedly connected to the right side of the storage tank. A range adjustment component is provided at the end of the water supply pipe away from the storage tank. The range adjustment component includes a support frame and a spraying disc. The support frame is fixedly connected to the top of the trolley near the right side of the storage tank. The water supply pipe passes through and is fixedly connected to the top of the support frame, communicating with the spraying disc. The spraying disc is fixedly connected to the top of the support frame. A spray nozzle is provided on the right side of the spraying disc. A baffle is rotatably connected to the right side of the outer wall of the spraying disc near the spray nozzle. A support disc is fixedly connected to the bottom end of the baffle. The support disc is rotatably connected to the outer wall of the water supply pipe at the bottom end of the spraying disc. An adjustment disc is vertically slidably connected to the inner wall of the middle part of the spraying disc. A drive component is provided at the bottom end of the support disc. A water volume adjustment component is provided on the upper part of the spraying disc and the adjustment disc.

[0006] As a further description of the above technical solution:

[0007] The drive assembly includes an adjusting block and a guide rod. The guide rod is fixedly connected to the bottom end of the support plate. The adjusting block slides on the top end of the support frame. The adjusting block has guide grooves extending vertically through both the front and rear sides. The support plate is slidably connected to the inner wall of the front guide groove. The adjusting block is positioned on the top end of the support frame by bolts.

[0008] As a further description of the above technical solution:

[0009] A positioning rod is fixedly connected to the inner wall of the spraying disc, and the adjusting disc passes through and is slidably connected to the outer wall of the positioning rod.

[0010] As a further description of the above technical solution:

[0011] The baffle is designed to be arc-shaped.

[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by loosening the bolts, the adjusting block is pushed to drive the two sets of guide rods and the two sets of support discs to rotate, so that the two sets of baffles rotate synchronously, thereby realizing the blocking or opening adjustment of the spraying nozzles on the right side of the two sets of spraying discs. After the adjustment is in place, the angle can be locked by tightening the bolts, so that the spraying coverage range can be flexibly adjusted according to different operation scenarios, avoiding overlapping coverage or omissions, ensuring that the agent is evenly distributed to the target soil layer, and reducing agent waste.

[0022] 2. In this utility model, the rotating turntable drives the screw to raise and lower the adjusting disc, thereby changing the effective volume and flow channel cross-section of the internal cavity of the spraying disc, thus accurately controlling the outlet flow rate and pressure of the agent. This allows it to adapt to different soil types, such as using high pressure and low flow rate for clay and low pressure and high flow rate for sand, ensuring that the agent penetrates and distributes in the best state. The overall device has good applicability. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a soil remediation agent uniform spraying device, comprising a storage tank 1 and a trolley 41. Both the storage tank 1 and the trolley 41 are existing structures in the prior art. A water pump is installed inside the storage tank 1 to transport the agent solution to the spraying plate 21 via a water pipe 4. The storage tank 1 is used to store and hold the soil remediation agent solution. The trolley 41 provides mobility for easy transfer between different work areas. The storage tank 1 is fixedly connected to the top of the trolley 41, and the water pipe 4 is fixedly connected to the right side of the storage tank 1. The water pipe 4 serves as a channel for the agent to flow from the storage tank 1 to the spraying plate 21. The water pipe 4 is located away from the storage tank 1. One end of the tank 1 is provided with a range adjustment component 2. The range adjustment component 2 is used to change the spray range of the agent to adapt to different spraying needs. The range adjustment component 2 includes a support frame 27 that provides support and a spraying disc 21 that sprays water from the water supply pipe 4 outward through the spraying nozzle 29. The support frame 27 is fixedly connected to the top of the trolley 41 near the right side of the storage tank 1. The water supply pipe 4 passes through and is fixedly connected to the top of the support frame 27 and is connected to the spraying disc 21. The spraying disc 21 is fixedly connected to the top of the support frame 27. A spraying nozzle 29 is opened on the right side of the spraying disc 21. The agent is finally sprayed out from the spraying nozzle 29 to form a jet or atomization.

[0031] Furthermore, a baffle 22 is rotatably connected to the outer wall of the spray disc 21 near the right side of the spray nozzle 29. The baffle 22 can block or open the spray nozzle 29 by rotating, thereby adjusting the spray angle range. A support plate 26 is fixedly connected to the bottom end of the baffle 22. The support plate 26 is connected to the baffle 22 and driven to rotate by a drive assembly. The support plate 26 is rotatably connected to the outer wall of the water supply pipe 4 at the bottom end of the spray disc 21. An adjusting plate 210 is vertically slidably connected to the inner wall of the middle part of the spray disc 21. The adjusting plate 210 can change the volume or shape of the internal cavity of the spray disc 21 by moving up and down, thereby assisting in the adjustment of flow rate or pressure. A drive assembly is provided at the bottom end of the support plate 26. The drive assembly is used to drive the support plate 26 and the baffle 22 to rotate. A water volume adjustment assembly 3 is provided on the upper part of the spray disc 21 and the adjusting plate 210. The water volume adjustment assembly 3 is used to control the volume or shape of the internal cavity of the spray disc 21, thereby adjusting the flow rate and pressure of the agent spraying per unit time.

[0032] Reference Figure 1 , Figure 2 and Figure 4The driving assembly includes an adjusting block 23 that moves in conjunction with the guide groove 25 to drive the guide rod 28, support plate 26, and baffle 22 to rotate, and a guide rod 28 that drives the support plate 26 and baffle 22 to rotate to adjust the spray range. The guide rod 28 is fixedly connected to the bottom end of the support plate 26. The bottom end of the support plate 26 is provided with a ring fixed to the outer wall of the water pipe 4 to support the support plate 26. The adjusting block 23 slides on the top of the support frame 27. The adjusting block 23 has guide grooves 25 that extend vertically and vertically on both the front and rear sides to accommodate the guide rod 28 and transmit the linear movement of the adjusting block 23 to the guide rod 28 through the groove wall, forcing the guide rod 28 and support plate 26 to rotate. The support plate 26 is slidably connected to the inner wall of the front guide groove 25. The adjusting block 23 is pressed and positioned on the top of the support frame 27 by bolts 24. After adjustment, tightening the bolts 24 can fix the adjusting block 23, thereby locking the angle of the baffle 22.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The inner wall of the spray disc 21 is fixedly connected to a positioning rod 211 that passes through the adjusting disc 210, ensuring that the adjusting disc 210 can only slide smoothly in the vertical direction and preventing deflection or jamming. The adjusting disc 210 passes through and is slidably connected to the outer wall of the positioning rod 211. The baffle 22 is arc-shaped, which allows it to better fit the outer wall of the spray disc 21, effectively sealing and guiding the flow at different angles. A sealing device is fixedly connected at the contact surface between the inner wall of the baffle 22 and the spray disc 21, and at the contact surface between the outer wall of the adjusting disc 210 and the inner wall of the spray disc 21. The sealing gasket increases the sealing performance and prevents the agent from leaking from the gaps in the moving parts, ensuring that all the agent is sprayed from the spray nozzle 29. The inner wall of the spray plate 21 is hollow, which forms the necessary chambers to collect and stabilize the agent sprayed from the spray nozzle 29, while providing movement space for the adjustment plate 210. Two sets of range adjustment components 2 are provided and are symmetrically arranged with the center line of the support frame 27 as the axis of symmetry. Through the symmetrically arranged range adjustment components 2, simultaneous spraying on both sides can be achieved, improving the coverage width and uniformity of a single operation.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The water volume regulating component 3 includes a screw 32 for converting rotational motion into linear motion and driving the regulating disc 210 to rise and fall via a thread, and a turntable 31 for facilitating the rotation of the screw 32. The screw 32 is rotatably connected to the top of the regulating disc 210, and the turntable 31 is fixedly connected to the top of the screw 32. The screw 32 passes through and is threadedly connected to the top of the spray disc 21, converting the rotational motion of the screw 32 into the linear rising and falling motion of the regulating disc 210, thereby changing the cross-sectional area of ​​the flow channel to achieve water volume regulation.

[0035] Working principle: During use, the soil remediation agent solution is injected into the storage tank 1 fixed on top of the trolley 41. The mobility of the trolley 41 allows for transfer of the device to different work areas. The agent in the storage tank 1 is then transferred to the spraying disc 21 via a water pump and a water pipe 4 fixedly connected to the right side. The hollow inner wall of the spraying disc 21 helps to collect and stabilize the agent. Simultaneously, two sets of range adjustment components 2 are symmetrically arranged around the center line of the support frame 27, achieving simultaneous and uniform spraying from both sides. Before spraying, the positioning of the adjusting block 23 can be released by rotating the bolt 24, and then the adjusting block 23 can be pushed. The adjusting block 23 moves the guide groove 25, simultaneously driving... As the guide rod 28 rotates, it slides on the inner wall of the guide groove 25, thereby driving the support plate 26 to rotate. The arc-shaped baffle 22 fixedly connected to the top of the support plate 26 rotates accordingly, realizing the blocking or opening adjustment of the spraying port 29 opened on the right side of the spraying plate 21. After the adjustment is in place, the positioning adjustment block 23 is pressed by flipping the rotating bolt 24 to lock the angle of the baffle 22. At the same time, the turntable 31 fixed to the top of the screw 32 can be rotated to drive the screw 32 to rotate, converting the rotational motion into the linear lifting motion of the adjustment plate 210. By changing the internal cavity volume of the spraying plate 21, the pressure and flow rate of the agent are adjusted, and finally the agent is evenly sprayed from the spraying port 29 to complete the soil remediation operation.
