Description

Technical Field

[0001] The invention relates to the technical field of soil remediation, in particular to a soil remediation agent sprayer with an adjustable spraying angle for soil remediation. Background Art

[0002] Soil remediation refers to the use of physical, chemical and biological methods to treat polluted soil, protect the ecological environment and human health, and restore its normal functions. Soil remediation technology can be roughly divided into three methods: physical, chemical and biological. Chemical remediation mainly uses spraying remediation agents to repair the soil. At the same time, chemical remediation is also the main means of soil remediation. Soil remediation agent sprayer is a kind of equipment specially used to spray soil remediation agent evenly on the surface of contaminated soil. Soil remediation agent sprayer plays a key role in the soil remediation process. It promotes chemical reaction or biodegradation between the remediation agent and the pollutants in the soil by spraying the remediation agent efficiently and evenly, so as to achieve the purpose of purifying the soil and restoring the ecological function of the soil. When the soil remediation agent sprayer sprays the soil with the remediation agent, most of its spraying discs are fixed in position, and its spraying angle is also uniform and unchanged, and its spraying angle cannot be adjusted, thereby reducing the spraying efficiency of the soil remediation agent sprayer and making it inconvenient to repair the soil later; In order to overcome the above defects, prior art 1 (application number CN202310168275.5, Chinese patent with application date of 2023-02-27) is a soil remediation agent spraying device for soil remediation, which drives the sprayer to swing left and right for spraying by controlling the rotation of the first connecting frame. At the same time, when the first connecting frame rotates, it also drives the nut ring to rotate, and then drives the sliding frame to move through the threaded bar, so that the height of the sprayer can be changed, so that it can achieve left and right swing spraying while moving up and down, so that the range of spraying soil remediation agent is wide; There is also prior art 2 (Chinese patent with publication number CN202311537587.5 and application date of 2023-11-17). In a soil remediation agent spraying device, a top block in a shell is lifted up, and the top block is lifted up to drive the fixed plate to rotate around the rotating shaft 3, and the rotation of the fixed plate drives the nozzle to rotate, so that the nozzle can be deflected and adjusted in real time according to the vehicle speed, so that the nozzle always sprays the upper and lower surfaces of the soil layer, thereby making the soil remediation agent sprayed more evenly; And prior art 3 (Chinese patent with publication number CN202020919071.2 and application date 2020-05-27) In a soil remediation agent sprayer for soil remediation, a fourth rotating roller is driven by a motor to move, the fourth rotating roller drives the active gear plate to move, the active gear plate is meshed with the driven gear plate to drive the driven gear plate to move, and the driven gear plate drives the first rotating roller to move, which solves the problem that most of the general soil remediation agent spraying methods are manual spraying, the degree of intelligence is not enough, and as the remediation range increases, the labor intensity will increase; Although the prior art can improve the spraying angle of the spraying disc, thereby increasing the spraying range of the spraying disc, when the soil remediation agent sprayer sprays the soil with the remediation agent, there is no leakage detection mechanism to collect and monitor the liquid leaked from the spraying disc, which will lead to waste of the remediation agent and reduce the remediation efficiency of the soil remediation agent sprayer; Therefore, we propose a soil remediation agent sprayer with adjustable spraying angle for soil remediation, so as to solve the above-mentioned problems.

When the soil repair agent sprayer repairs the soil, the servo motor is started to drive the half gear to rotate through the transmission component at the same time.

At this time, the cleaning plate that reciprocates up and down can not only mix and stir the stirred and mixed repair agent more fully through a row of guide grooves opened inside it, but also can reciprocate and clean and scrape the repair agent stuck to the inner wall of the storage barrel through the cleaning plate that reciprocates up and down, so as to prevent the later repair agent from sticking to the inner wall of the storage barrel and affecting the later mixing and stirring; (5) A float is provided. The float is installed by sliding through the groove on the left inner wall of the storage barrel. Then, a float is provided on the top of the float.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The present invention provides the following technical solutions: Embodiment 1, in order to solve the problem that the spraying angle of the spraying disc 18 of the existing soil remediation agent sprayer cannot be adjusted, the spraying range of the spraying disc 18 is reduced, and the spraying efficiency of the soil remediation agent sprayer is reduced, the following is disclosed: The mobile frame 1 and the storage barrel 2, wherein the storage barrel 2 is placed above the mobile frame 1, and a feed pipe 9 is installed through the top slot seal of the storage barrel 2, and a discharge pipe is installed through the bottom outer slot seal of the storage barrel 2; It also includes: two moving wheels 4 are rotatably installed at both ends of the bottom of the moving frame 1, a push handle is installed on the right end of the moving frame 1 by screws, and the push handle is in an inclined shape, a control cabinet 7 is installed on the top of the moving frame 1 by screws, and an alarm 8 is installed on the top of the control cabinet 7 by screws, an anti-collision beam 6 is installed on the top of the moving frame 1 by screws, and the inside of the anti-collision beam 6 is hollow, and the inner side of the anti-collision beam 6 corresponds to the storage barrel 2; The top of the storage barrel 2 is slotted and sealed to be rotatably mounted with a discharge pipe 17, and the bottom end of the discharge pipe 17 extends through and extends to the bottom inner side of the storage barrel 2, and a spraying disc 18 is sealed and mounted on the top of the discharge pipe 17, a servo motor 10 is screwed to the top of the storage barrel 2, and a rotating shaft 11 is connected to the output end of the servo motor 10, and the rotating shaft 11 is rotatably mounted inside the storage barrel 2, and a row of stirring rods 12 are installed through the outer side of the rotating shaft 11; A rotating gear 20 is installed through the outer side of the top of the discharge pipe 17 , and a half gear 19 is meshedly connected to the outer side of the rotating gear 20 , and the half gear 19 is rotatably installed on the outer side of the top of the storage barrel 2 .

[0018] The output end of the servo motor 10 is connected to the transmission assembly 24, and the outer side of the transmission assembly 24 is connected to the output end of the half gear 19. The top outer side of the discharge pipe 17 is wrapped with a torsion spring 27, and the outer side of the torsion spring 27 is connected to the storage barrel 2. At the same time, a limiting block is set on the top outer side of the discharge pipe 17.

[0019] The right inner wall of the storage barrel 2 is grooved and a cleaning plate 16 is slidably installed therethrough, and the cleaning plate 16 is in an arc shape, and a row of guide grooves 29 are provided inside the cleaning plate 16, and the outer side of the cleaning plate 16 is fitted and connected to the right inner wall of the storage barrel 2, and a rotating rod 14 is rotatably installed on the bottom groove of the storage barrel 2, and the left end of the rotating rod 14 is meshedly connected to the rotating shaft 11 through a bevel gear set 13, and a beating block 15 is installed through the right end of the rotating rod 14, and the cleaning plate 16 is fitted and connected to the outer side of the top of the beating block 15.

[0020] A bidirectional screw rod 5 is rotatably installed in the internal groove of the movable frame 1, and the two ends of the bidirectional screw rod 5 are respectively threadedly connected with positioning plates 3, the two positioning plates 3 are both in an arc shape, and the inner sides of the two positioning plates 3 are fitted with the storage barrel 2.

[0021] like Figure 1-Figure 10As shown, when the soil remediation agent sprayer sprays the remediation agent on the soil to remediate the soil, the rotating servo motor 10 is used to drive the half gear 19 to rotate through the transmission component 24 at the same time. Because the outer side of the half gear 19 is meshedly connected with the rotating gear 20, the discharge pipe 17 connected to the inner side of the rotating gear 20 can be driven to drive the spraying disc 18 to reciprocate on the outer side of the top of the storage barrel 2 through the torsion spring 27 while the half gear 19 rotates, and then the remediation agent inside the storage barrel 2 is transported to the spraying disc 18 through the discharge pipe 17 through the pump body and sprayed. At this time, the reciprocating spraying disc 18 can expand its spraying range, thereby improving the spraying efficiency of the soil remediation agent sprayer; When the servo motor 10 is started to drive a row of stirring rods 12 installed at the bottom of the rotating shaft 11 to mix and stir the repair agent delivered by the feeding pipe 9, the bottom of the rotating shaft 11 will simultaneously drive the slapping block 15 installed through the outer end of the rotating rod 14 through the bevel gear set 13 to reciprocately squeeze and slap the bottom of the cleaning plate 16. At this time, the cleaning plate 16 will reciprocate up and down through the squeezing and slapping force, so that the repair agent inside the storage barrel 2 can be more fully mixed and stirred through a row of guide grooves 29 opened on its inner side. At the same time, the cleaning plate 16 that reciprocates up and down can also reciprocately clean and scrape the repair agent stuck to the inner wall of the storage barrel 2 to prevent the repair agent from sticking to the inner wall of the storage barrel 2 and affecting the subsequent mixing and stirring.

[0022] Embodiment 2 is different from Embodiment 1 in that the repair agent leaking from the connection between the discharge pipe 17 and the spraying plate 18 can be collected by the collecting plate 25, which can not only avoid the waste of the repair agent, but also remind the staff to deal with the leakage and seepage problem in time. The outer groove of the storage barrel 2 is slidably mounted with a collecting plate 25 through two tension springs 26, and a collecting groove is opened inside the collecting plate 25. The top of the collecting plate 25 corresponds to the connection between the discharge pipe 17 and the spraying plate 18, and the two tension springs 26 are arranged on both sides of the storage barrel 2.

[0023] Both sides of the storage barrel 2 are grooved and second gravity sensors 28 are installed by screws. The two second gravity sensors 28 have the same structure, and the tops of the two second gravity sensors 28 correspond to the bottom sides of the collection plate 25. At the same time, the second gravity sensor 28 is connected to the alarm 8 through a wireless transmission module.

[0024] like Figure 1-Figure 8 As shown, when leakage or seepage occurs at the connection between the discharge pipe 17 and the spraying plate 18, the leaked repair agent will drip into the inside of the collecting plate 25, thereby preventing the repair agent from falling on the outside of the sprayer and causing material waste. The sprayer can also be protected from corrosion due to the chemical composition of the repair agent, thereby increasing the service life of the sprayer. When the repair agent collected in the collecting tray 25 reaches a certain weight, the collected repair agent will drive the collecting tray 25 to descend due to its own weight. At this time, the collecting tray 25 will squeeze and touch the second gravity sensors 28 installed at both ends of the storage barrel 2. Then, the two second gravity sensors 28 will transmit the information to the alarm 8 through the wireless transmission module and promptly remind the staff to deal with the leakage problem in time, which is more practical. Finally, the elastic force of the two tension springs 26 can be used to elastically reset the position of the collecting tray 25 after the descending movement for later reuse.

[0025] Embodiment 3 is different from Embodiment 2 in that the capacity of the repair agent stored in the storage barrel 2 can be monitored. When the capacity of the repair agent is reduced, the alarm 8 will sound an alarm to remind the staff to add the repair agent in time. A moving plate 21 is slidably mounted through a groove on the left inner wall of the material storage barrel 2 , and a floating ball 22 is provided on the top of the moving plate 21 .

[0026] A first gravity sensor 23 is correspondingly disposed at the bottom of the moving plate 21 , and the first gravity sensor 23 is mounted on the left side of the bottom of the material storage barrel 2 by means of screws.

[0027] like Figure 1-Figure 3 As shown, when the feed pipe 9 transports the repair agent to the interior of the storage barrel 2, the float 22 will drive the movable plate 21 to move upward inside the storage barrel 2 through the buoyancy of the repair agent. When the capacity of the repair agent is reduced and the repair agent needs to be added, the reduced repair agent drives the float 22 to descend. At this time, the descending float 22 will simultaneously drive the movable plate 21 to squeeze and touch the first gravity sensor 23 provided on the inner side of the bottom of the storage barrel 2. Then the first gravity sensor 23 will transmit the information to the alarm 8 through the wireless transmission module and sound an alarm to remind the staff to add the repair agent in time, thereby realizing the monitoring of the repair agent capacity inside the storage barrel 2, improving the multifunctional performance of the sprayer, and completing a series of tasks.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
