Description

Technical Field

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

[0002] Soil remediation agents are substances used to improve soil quality and restore soil function, primarily for treating contaminated soils such as those contaminated with heavy metals or organic pollutants. Some soil remediation agents (especially bioremediation agents) need to be dissolved in water to be absorbed by the soil and exert their effects; that is, after dissolution, the remediation agent can be more evenly distributed in the soil, thereby improving the remediation effect. Existing soil remediation agent spraying devices typically use agitators or spiral blades to stir the solution to ensure thorough mixing. However, stirring is usually done while mixing the agent with water, followed by long-term continuous spraying. During long-term continuous spraying, uneven concentration of the solution can occur due to sedimentation and stratification effects, affecting the actual effectiveness of the agent. To address this, those skilled in the art have used a drive motor to continuously drive the agitator or spiral blades to stir the solution. However, the stirring and spraying components are designed independently, and the drive motor cannot drive the nozzle to swing, reducing the spraying range. Therefore, a soil remediation agent spraying device for soil remediation is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a soil remediation agent spraying device to solve the above-mentioned problems.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A soil remediation agent spraying device, comprising:

[0006] A base plate, on which a support frame is provided;

[0007] A mixing tank is disposed on the base plate, and the top surface of the mixing tank has an opening;

[0008] The stirring assembly includes a drive motor mounted on the support frame, a first rotating shaft with one end connected to the output shaft of the drive motor, the first rotating shaft extending through the opening into the mixing tank, and a stirring blade mounted on the other end of the first rotating shaft.

[0009] The spraying assembly includes a guide rod rotatably connected to the first rotating shaft, a nozzle being provided on the guide rod, and the nozzle being connected to a water suction pipe; a second rotating shaft being provided on the support frame and rotating synchronously with the first rotating shaft, an eccentric wheel being provided at one end of the second rotating shaft near the guide rod, and an eccentric ring corresponding to the eccentric wheel being provided on the guide rod.

[0010] Optionally, a first pulley is provided on the output shaft of the drive motor, and a second pulley is provided at one end of the first rotating shaft. The first pulley and the second pulley are connected by a first belt.

[0011] Optionally, the support frame is provided with a first bearing seat, a first bearing is installed in the first bearing seat, and the first rotating shaft is installed on the first bearing.

[0012] Optionally, one end of the guide rod is provided with a ring, which is sleeved on the first rotating shaft. The first rotating shaft is provided with a limiting ring, which is located on both sides of the ring.

[0013] Optionally, the support frame is provided with a second bearing seat, the second bearing seat is mounted on the second bearing seat, and the second rotating shaft is mounted on the second bearing.

[0014] Optionally, a third pulley is provided on the first rotating shaft, and a fourth pulley is provided at one end of the second rotating shaft. The third pulley and the fourth pulley are connected by a second belt.

[0015] Optionally, the bottom surface of the eccentric wheel is provided with a tray.

[0016] Optionally, a retaining ring is provided on the guide rod, which is used to fix the water suction pipe.

[0017] Optionally, a water pipe retainer is provided on the inner wall of the mixing tank.

[0018] Compared with existing technologies, this invention has the following advantages: When spraying soil remediation agent, the agent and water are injected into the mixing tank through the opening. The drive motor is started, driving the first rotating shaft to rotate, thereby driving the stirring blades to stir the agent solution. After sufficient stirring, the nozzle is opened, and the agent solution in the mixing tank flows to the nozzle through the suction pipe and is sprayed onto the soil. During this process, the drive motor continuously drives the first rotating shaft to rotate, ensuring the stirring blades continuously stir the agent solution. The second rotating shaft rotates synchronously with the first rotating shaft, driving the eccentric wheel. One side of the eccentric wheel is always in contact with the inner side of the eccentric ring, meaning the eccentric wheel forces the eccentric ring to oscillate periodically. This causes the guide rod to drive the nozzle to oscillate periodically, thereby increasing the spraying range of the nozzle. The soil remediation agent spraying device provided by this invention not only allows the drive motor to continuously drive the stirring blades to stir the agent solution, but also drives the spraying components to oscillate the nozzle, thereby increasing the spraying range.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1 to 5This utility model provides a soil remediation agent spraying device, including a base plate 10, a mixing tank 20, a stirring assembly 30, and a spraying assembly 40. A support frame 11 is fixedly mounted on the base plate 10, with the support column of the support frame 11 located at one end of the top surface of the base plate 10. The mixing tank 20 is mounted on the base plate 10, and its top surface has an opening 21, allowing the soil remediation agent and water to be injected into the mixing tank 20 through the opening 21 to form a solution. The stirring assembly 30 includes a drive motor 31 mounted on the support frame 11 and a first rotating shaft 32, one end of which is connected to the output shaft of the drive motor 31. When the drive motor 31 operates, it drives the first rotating shaft 32 to rotate. The first rotating shaft 32 passes through the opening 21 and extends into the mixing tank 20, with a stirring blade 33 provided at the end of the first rotating shaft 32 extending into the mixing tank 20. When the drive motor 31 operates, it drives the first rotating shaft 32 to rotate, thereby causing the stirring blades 33 to rotate and stir the liquid medicine. The spraying assembly 40 includes a guide rod 41 rotatably connected to the first rotating shaft 32. A nozzle 42 is provided on the guide rod 41, and the nozzle 42 is connected to a water suction pipe 43. The water suction pipe 43 is a flexible hose, and its end away from the nozzle 42 is submerged at the bottom of the mixing tank 20. It should be noted that during the stirring process, the stirring blades 33 and the water suction pipe 43 do not interfere with each other. A second rotating shaft 44 is provided on the support frame 11, which rotates synchronously with the first rotating shaft 32. An eccentric wheel 45 is provided at the end of the second rotating shaft 44 near the guide rod 41, and an eccentric ring 411 corresponding to the eccentric wheel 45 is provided on the guide rod 41. When the second rotating shaft 44 rotates, the guide rod 41 performs a periodic oscillating motion under the cooperation of the eccentric wheel 45 and the eccentric ring 411, thereby driving the nozzle 42 to perform a periodic oscillating motion.

[0031] Specifically, when spraying the soil remediation agent, the agent and water are injected into the mixing tank 20 through the opening 21. The drive motor 31 is started, which drives the first rotating shaft 32 to rotate, thereby driving the stirring blades 33 to stir the agent solution. After thorough stirring, the nozzle 42 is opened, and the agent solution in the mixing tank 20 flows through the suction pipe 43 to the nozzle 42 and is sprayed onto the soil. During this process, the drive motor 31 continuously drives the first rotating shaft 32 to rotate, so that the stirring blades 33 continuously stir the agent solution. The second rotating shaft 44 rotates synchronously with the first rotating shaft 32, and the second rotating shaft 44 drives the eccentric wheel 45. One side of the eccentric wheel 45 is always in contact with the inner side of the eccentric ring 411, that is, the eccentric wheel 45 forces the eccentric ring 411 to oscillate periodically, thereby causing the guide rod 41 to drive the nozzle 42 to oscillate periodically, thus increasing the spraying range of the nozzle 42. The soil remediation agent spraying device provided by this utility model can not only drive the stirring blades 33 to stir the liquid continuously without interruption, but also drive the spraying assembly 40 to swing the nozzle 42, thereby increasing the spraying range.

[0032] Furthermore, a first pulley 34 is provided on the output shaft of the drive motor 31, and a second pulley 35 is provided at one end of the first rotating shaft 32. The first pulley 34 and the second pulley 35 are connected by a first belt 36.

[0033] Furthermore, a first bearing seat 37 is provided on the support frame 11, and a first bearing is installed inside the first bearing seat 37.

[0034] Furthermore, a ring 412 is provided at one end of the guide rod 41, and the ring 412 is sleeved on the first rotating shaft 32. A limiting ring 38 is provided on the first rotating shaft 32, and the limiting ring 38 is located on both sides of the ring 412. Through this technical solution, the ring 412 can rotate about the first rotating shaft 32 as the rotation axis, that is, the guide rod 41 can rotate about the first rotating shaft 32 as the rotation axis.

[0035] Furthermore, a second bearing seat 46 is provided on the support frame 11, and a second bearing is installed on the second bearing seat 46. The second rotating shaft 44 is installed on the second bearing. A third pulley 39 is provided on the first rotating shaft 32, and a fourth pulley 47 is provided at one end of the second rotating shaft 44. The third pulley 39 and the fourth pulley 47 are connected by a second belt 48. When the first rotating shaft 32 rotates, the first rotating shaft 32 drives the third pulley 39, and the third pulley 39 sequentially drives the second belt 48, the fourth pulley 47, the second rotating shaft 44, and the eccentric wheel 45. A tray 49 is provided on the bottom surface of the eccentric wheel 45, and the top surface of the tray 49 is in contact with the bottom surface of the guide rod 41, thereby improving the stability of the guide rod 41.

[0036] Furthermore, a fixing ring 413 is provided on the guide rod 41, which is used to fix the water suction pipe 43, thereby fixing the nozzle 42 to the guide rod 41. A water pipe retainer (not shown) is provided on the inner wall of the mixing tank 20, that is, the water suction pipe 43 located in the mixing tank 20 is retained in the water pipe retainer to prevent the water suction pipe 43 from contacting the stirring blade 33 during stirring.
