Description

Technical Field

[0001] The utility model relates to the technical field of land restoration devices, in particular to a soil pollution restoration reagent spraying mechanism. Background Art

[0002] Soil pollution refers to the harmful substances produced by human activities entering the soil, causing soil quality to deteriorate and affecting the normal function of the soil and the balance of the ecosystem. In order to prevent soil erosion, soil loss and reduce soil pollution, soil pollution needs to be repaired.

[0003] The applicant retrieved and obtained the following prior art. Specifically, the patent with announcement number CN212190592U discloses a reagent sprayer for soil pollution remediation, including a motion mechanism and a spraying mechanism. The bottom end of the spraying mechanism is fixedly connected to the upper end of the motion mechanism. By fixing the motion mechanism at the bottom end of the spraying mechanism, the user does not need to control the sprayer outside in bad weather. By fixing the single-chip microcomputer at the top of the carrier plate and arranging an ultrasonic detector at the side end, the motion mechanism moves under the set single-chip microcomputer program. The ultrasonic detector transmits the detected signal to the single-chip microcomputer, effectively avoiding obstacles and protecting the sprayer. By arranging a stirring tube and stirring blades inside the bottle cavity, the reagent and water are poured into the bottle cavity. When the power is turned on, the liquid in the bottle cavity is stirred. When the machine stops, the stirring tube and stirring blades stop stirring, ensuring that the reagent is not deposited at the bottom of the bottle cavity.

[0004] It can be seen from the above patent that although the reagent sprayer for soil pollution remediation can save the user from having to control the sprayer outside in bad weather and can avoid obstacles to protect the sprayer, and the stirring tube and stirring blades can ensure that the reagent is not deposited at the bottom of the bottle cavity, in actual use, since the nozzle is fixedly mounted on the receiving tube and cannot be adjusted in position, it is impossible to ensure the spray coverage of the nozzle on the contaminated soil when spraying the remediation agent, which reduces the spraying efficiency and is inconvenient to use.

[0026] Embodiment 1:

[0027] The utility model provides a soil pollution remediation reagent spraying mechanism.

[0028] In one embodiment of the utility model, a soil pollution remediation reagent spraying mechanism is arranged on the soil pollution remediation device and is used for spraying reagents. The soil pollution remediation device includes a frame and a motion mechanism, a stirring mechanism and a reagent box arranged on the frame. A liquid supply component is arranged in the reagent box, including a mounting cylinder 1, an adjusting rod 2, a nozzle 3 and a connecting component. The mounting cylinder 1 is vertically arranged on the frame, and the adjusting rod 2 is installed in the mounting cylinder 1 in a limited and movable manner. A through groove 4 is opened on the outer wall of the mounting cylinder 1 along its extension direction, so that the nozzle 3 can be installed on the adjusting rod 2 through the connecting component and can move along the extension direction of the mounting cylinder 1, and the nozzle 3 is connected to the liquid supply component in the reagent box through a connecting pipe 5.

[0029] Specifically, the utility model provides a soil pollution remediation reagent spraying mechanism, which can be installed on a soil pollution remediation device for spraying reagents when in use. The soil pollution remediation device includes a frame and a motion mechanism, a stirring mechanism and a reagent box arranged on the frame. A liquid supply component is arranged in the reagent box. The motion mechanism can drive the frame to move in the soil area that needs to be repaired. The user does not need to manually operate or control the soil pollution remediation device outdoors under bad weather conditions. The stirring mechanism can not only fully mix water and soil remediation reagents, but also prevent the reagents from being deposited at the bottom of the reagent box. The liquid supply component can provide reagents to the nozzle 3, and spray the reagents onto the contaminated soil through the nozzle 3 to achieve spraying remediation of the contaminated soil. The liquid supply component includes but is not limited to components or devices such as water pumps and water pipes that supply reagents to the nozzle 3.

[0030] It is worth noting that the soil pollution remediation device and its frame, motion mechanism, stirring mechanism and reagent box are all prior art, specifically a reagent sprayer for soil pollution remediation disclosed by the applicant in the patent with announcement number CN212190592U. The utility model, as a technical improvement of the reagent sprayer for soil pollution remediation, can solve the problem that the reagent sprayer for soil pollution remediation cannot ensure the spraying coverage rate of the nozzle 3 on the contaminated soil when spraying the remediation agent, which reduces the spraying efficiency and is inconvenient to use.

[0031] Furthermore, if Figures 1 to 3 As shown, since the mounting tube 1 is vertically arranged on the frame, and the adjusting rod 2 is installed in the mounting tube 1 in a limited and movable manner, the limited and movable manner can be optionally threaded, and a through groove 4 is opened on the outer wall of the mounting tube 1 in the up and down directions, so that the nozzle 3 can be installed on the adjusting rod 2 through the connecting assembly. When it is necessary to adjust the installation position of the nozzle 3, the staff rotates the adjusting rod 2 counterclockwise relative to the mounting tube 1, thereby causing the connecting assembly to drive the nozzle 3 to move upward, thereby increasing the spraying coverage rate of the nozzle 3 on the contaminated soil when spraying the reagent, reducing the number of repeated spraying of the contaminated soil by the soil pollution remediation device, and improving the spraying efficiency; at the same time, when the area of ​​contaminated soil to be sprayed is small, the staff rotates the adjusting rod 2 clockwise relative to the mounting tube 1, so that the connecting assembly drives the nozzle 3 to move downward, thereby ensuring the spraying effect on a smaller area of ​​contaminated soil, which is convenient and reliable to use. In addition, since soil remediation reagents are usually highly corrosive, and the nozzle 3 is connected to the liquid supply component through the connecting pipe 5, the connecting pipe 5 can be selected as a polyvinyl chloride pipe in the prior art. The polyvinyl chloride pipe has the characteristics of chemical corrosion resistance, rust resistance, self-extinguishing, flame retardancy, smooth inner wall and not easy to form scale, etc., which facilitates long-term transportation of the reagents.

[0032] Compared with the prior art, when the soil pollution remediation reagent spraying mechanism of the utility model is in use, the staff rotates the adjusting rod 2 to make the connecting assembly drive the nozzle 3 to move upward or downward, thereby improving the adaptability of the nozzle 3 to contaminated soils of different areas, and thereby improving the spraying coverage rate of the nozzle 3 on the contaminated soil when spraying the reagent, reducing the number of times the soil pollution remediation device repeatedly sprays the contaminated soil, improving the spraying efficiency, and being simple to operate, convenient to use, and reliable.

[0033] In one embodiment, a thread is formed on the outer wall of the adjusting rod 2, and the connecting assembly includes a connecting seat 6 and a collar 7 that is threadedly matched with the adjusting rod 2. A mounting column 8 is formed on the outer wall of the collar 7. The mounting column 8 passes through the through slot 4 and is detachably mounted with the connecting seat 6. A through hole is formed on the mounting column 8, and the connecting seat 6 is hollow and is used to mount the nozzle 3, so that the connecting pipe 5 can pass through the through hole and the connecting seat 6 and communicate with the nozzle 3. It can be understood that Figures 1 to 3 As shown, when the staff rotates the adjusting rod 2, the collar 7 is threadedly matched with the adjusting rod 2, so that the collar 7 can move up and down relative to the adjusting rod 2; further, since the mounting column 8 on the collar 7 passes through the through groove 4 and is detachably mounted with the connecting seat 6, and the connecting seat 6 is mounted with the nozzle 3, the detachable connection between the connecting seat 6 and the mounting column 8 can be selected as a threaded connection, so that it is convenient to disassemble and replace the connecting seat 6 and the nozzle 3, which is convenient for maintenance; at the same time, when the adjusting rod 2 is rotated to make the collar 7 move up and down, the nozzle 3 can move up and down synchronously with the collar 7, so as to achieve the upper and lower position adjustment of the nozzle 3, which is simple to operate, convenient to use, and has a simple and reasonable structural design. In addition, since a through hole is provided on the mounting column 8, and the connecting seat 6 is hollow, the connecting pipe 5 can pass through the through hole and the connecting seat 6 and communicate with the nozzle 3, so that it can not only realize the delivery of reagents to the nozzle 3, but also avoid the connecting pipe 5 from being exposed outside the mounting tube 1, and prevent the connecting pipe 5 from being damaged due to external factors after long-term use, etc., thereby extending the service life of the connecting pipe 5.

[0034] In one embodiment, a spherical joint is formed on the connection seat 6, and a spherical hinge seat is provided on the nozzle 3, so that the nozzle 3 and the connection seat 6 are spherically hinged. Figures 1 to 3 As shown, by connecting the seat 6 and the spherical hinge of the nozzle 3, the direction of the nozzle 3 can be adjusted to improve the adaptability to contaminated soil in different areas, making it more flexible and convenient to use.

[0035] In one embodiment, a plurality of through slots 4 are formed in an array along the circumference of the mounting tube 1, and the number of mounting posts 8, connection seats 6 and nozzles 3 is consistent with the number of through slots 4 and corresponds one to one. Figures 1 to 3 As shown, the plurality of nozzles 3 can increase the spraying area of ​​the soil pollution remediation device on the contaminated soil, thereby greatly improving the spraying efficiency.

[0036] In one embodiment, an annular flange 9 is formed on the inner wall of one end of the mounting tube 1, and the annular flange 9 is used to abut against the outer wall of the adjusting rod 2, and the other end of the mounting tube 1 is provided with an end cap 10 for detachably connecting with the frame, and the end cap 10 is provided with a through hole 11 for the connecting tube 5 to pass through, so that the connecting tube 5 can extend into the reagent box and communicate with the liquid supply component. Specifically, Figures 1 to 3 As shown, since the annular flange 9 abuts against the outer wall of the adjusting rod 2, the stability of the adjusting rod 2 in the mounting tube 1 can be ensured; at the same time, by providing an end cover 10 detachably connected to the frame at the lower end of the mounting tube 1, not only the inner cavity of the mounting tube 1 can be covered, but also the mounting tube 1 can be installed. In addition, through the through hole 11 provided on the end cover 10, the connecting pipe 5 can be extended into the mounting tube 1 and communicated with the nozzle 3 through the collar 7 and the connecting seat 6, and the structural design is simple and reasonable.

[0037] In one embodiment, one end of the adjusting rod 2 passes through the end cap 10 and is connected to a locking member, and the other end of the adjusting rod 2 passes through the annular flange 9 and extends out of the mounting tube 1 to form a polygonal boss. Figures 1 to 3 As shown, the lower end of the adjusting rod 2 passes through the end cover 10 and is connected with a locking member, so that the mounting tube 1 can be firmly mounted on the end cover 10, improving the installation stability of the mounting tube 1. Furthermore, the upper end of the adjusting rod 2 passes through the annular flange 9 and extends out of the mounting tube 1 and forms a polygonal boss, so that the staff can use an external wrench or other tool to rotate the adjusting rod 2, which is simple to operate.

[0038] In one embodiment, a hand wheel 12 is provided at one end of the adjusting rod 2 extending out of the mounting tube 1. Figure 1 As shown, since a hand wheel 12 is provided at the upper end of the adjusting rod 2, the staff can rotate the adjusting rod 2 without using external tools such as wrenches, which is convenient to use.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
