Technical Field

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

[0002] Patent application CN109332368A discloses a mobile soil remediation device combining physicochemical methods: It includes a housing containing a soil refining box and a soil remediation box; a feed inlet corresponding to the feed inlet of the soil refining box is located at the top rear end of the housing; a discharge outlet is located at the bottom of the soil refining box, and the discharge outlet of the soil remediation box is connected to the feed inlet of the soil remediation box; the soil remediation box includes an outer casing and an inner cavity; a heating wire is arranged around the outer wall of the inner cavity; a chemical storage tank is located at the top of the soil remediation box; a spray nozzle for spraying chemicals into the inner cavity is located on the side wall of the inner cavity, and the spray nozzle is connected to the chemical storage tank; an electrophoresis device for electrodialysis is located at the top of the inner cavity; this remediation vehicle, by combining three different soil remediation methods—thermodynamics, chemical remediation agents, and electrophoresis—can conveniently, quickly, and thoroughly remove various organic matter and heavy metal ions from contaminated soil.

[0003] Soil remediation encompasses various fields, while agricultural soil remediation involves diverse agricultural environments (such as greenhouses, open fields, orchards, and pastures) and different remediation technologies (bioremediation, physical remediation, and chemical remediation). For greenhouse soil remediation, issues such as soil compaction, salinization, pollution, and nutrient deficiencies require different treatments, including organic fertilizers, chemical fertilizers, and the addition of specific microbial agents or soil conditioners. However, for different types of vegetable greenhouses, we need to determine the optimal ratio of treatments. For example, leafy vegetables may require higher nitrogen content, while root vegetables may require more potassium. Different vegetable greenhouses may have different ratio values. Furthermore, soil remediation involves more than just nutrient replenishment; it may also involve adjusting pH levels and improving soil structure. Appropriate ratios need to be adjusted for different vegetable varieties.

[0004] In response, this invention presents a soil remediation spraying device that can adjust the required drug-to-water mixing ratio in different greenhouse vegetable soil compositions before spraying. Summary of the Invention

[0005] The purpose of this invention is to provide a soil remediation pesticide spraying device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a soil remediation chemical spraying device, comprising a main tank, a secondary tank disposed on one side of the main tank, the main tank being connected to a main pipe, the secondary tank being connected to a secondary conduit, a liquid mixing structure disposed at the bottom of the secondary tank, the main pipe and the secondary conduit both being connected to a centrifuge device, the main pipe and the secondary conduit being connected to multiple mixing structures disposed at equal intervals, each of the mixing structures being connected to a spraying system for a greenhouse, and the mixing structures and the centrifuge device being connected to a driving device for transmission.

[0007] The main tank has a perforation at the top, and a sliding piston is installed inside the main tank. The sliding piston is slidably connected to the inner wall of the main tank, and water inlets are opened at the bottom of both the main tank and the auxiliary tank.

[0008] Furthermore, the mixing structure includes a mixing hopper, which rotates in contact with the outer ring of the stirring blade. A cover plate is provided on the top of the mixing hopper, and the top of the stirring blade passes through the cover and is connected to the drive device. The cover plate is connected to one end of a symmetrically arranged proportional regulating valve, and the other ends of the two proportional regulating valves are respectively connected to the main pipe and the auxiliary pipe.

[0009] Furthermore, the centrifuge device includes a centrifuge cover plate, the bottom of which is connected to the centrifuge housing. The centrifuge housing has symmetrically opened cylindrical grooves, the inner wall of which slides in contact with the outer ring of the centrifuge impeller. The bottom of the centrifuge impeller passes through the centrifuge housing and is connected to the drive device. The two cylindrical grooves of the centrifuge housing are respectively connected to the main pipe and the secondary pipe, and the top of the centrifuge cover plate is respectively connected to the main pipe and the secondary pipe.

[0010] Furthermore, the liquid dispensing structure includes a fixed-value motor, the output end of which is connected to the top plate, the top plate is connected to an electric telescopic rod, the output end of which passes through the bottom of the auxiliary tank and is connected to a liquid equalization impeller, the liquid equalization impeller is slidably connected to a piston plate, the outer ring of the piston plate is in slidable contact with the inner wall of the auxiliary tank, the top of the auxiliary tank is connected to a top cover, and the bottom of the auxiliary tank is connected to multiple annularly arranged liquid outlet devices.

[0011] Furthermore, the liquid dispensing device includes a liquid storage tank, the top of which is connected to an auxiliary tank. The inner ring of the liquid storage tank is slidably connected to the liquid dispensing piston. The upper end of the inner ring of the liquid storage tank is connected to the outer ring of the liquid dispensing plate. The top of the liquid dispensing plate is connected to one end of a reset elastic element. The other end of the reset elastic element is connected to one end of a connecting rod. The other end of the connecting rod passes through the liquid storage tank and is connected to the bottom of the closing plug. A liquid injection threaded hole is opened at the upper end of the liquid storage tank. The liquid injection threaded hole is opened and closed by a screw plug.

[0012] Furthermore, the driving device includes a drive motor, the top of the output end of the drive motor is connected to a first gear, the first gear meshes with symmetrically arranged second gears, and each of the second gears is connected to a centrifugal impeller.

[0013] Furthermore, the output end of the drive motor is connected to the first pulley, which is connected to multiple second pulleys via a transmission belt, and each second pulley is connected to a stirring blade.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the soil remediation chemical spraying device is reasonable and has the following advantages:

[0015] (1) The repair drug is transported through the water and liquid mixing structure in the auxiliary tank, and then fully mixed by the liquid mixing structure to form a mixed repair drug with the water synthesis ratio. Then, the centrifugal device driven by the drive device carries the water in the main tank and the mixed repair drug in the auxiliary tank into multiple mixing structures along the main pipe and the auxiliary pipe. The water and mixed repair drug are evenly mixed according to the difference in each greenhouse. Finally, it is input into the spraying of each greenhouse, so as to adjust the ratio difference of the drug required by different varieties of greenhouse vegetables, thereby improving efficiency and evenly distributing the mixture.

[0016] (2) By rotating the fixed value motor by a fixed angle, the output end of the electric telescopic rod is aligned with the bottom of the storage tank containing the required medicine. The extension length of the electric telescopic rod is controlled according to the required amount of medicine. While slowly extending, the dispensing piston is pushed to move. The movement of the dispensing piston causes the medicine to push open the closing cap, thereby allowing the required amount of medicine to enter the auxiliary tank. Then, the closing cap is closed by the action of the reset elastic element to close the dispensing position at the top of the storage tank. At the same time, the extension length data of the electric telescopic rod to the storage tank needs to be saved for the next use. Finally, the electric telescopic rod is reset, so as to accurately control the dispensing volume, ensure that there is no error, and automate the process.

[0017] (3) The opening ratio is adjusted by two relative proportional regulating valves, and the centrifugal device pumps out water and mixed repair drugs under the same pressure, so as to adjust the ratio difference of the drug required by different varieties of greenhouse vegetables. The stirring blades fully mix water and mixed repair drugs, so as to quickly and efficiently adjust and mix the drug and water mixing ratio requirements of different varieties of greenhouse vegetables. At the same time, the two centrifugal impellers rotate at the same speed, so as to pump out the same pressure, thereby avoiding the error of pressure error that causes the subsequent proportional regulating valve adjustment to cause the water and mixed repair drug mixing ratio error due to different pressure. At the same time, the first gear and the symmetrically set second gear are driven by a drive motor, so as to ensure that the two centrifugal impellers rotate at the same time, thereby saving costs and ensuring the stability of the same speed, avoiding the error of the pressure value pumped by the two centrifugal impellers. The drive motor can not only drive the centrifugal impellers to rotate, but also drive the first pulley, the drive belt and multiple second pulleys to cause multiple stirring blades to rotate to mix water and mixed repair drugs, thereby further reducing costs.

Detailed Implementation

[0029] 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.

[0030] Please see Figure 1-10 The present invention provides a technical solution: a soil remediation chemical spraying device, comprising a main tank 1, a secondary tank 2 disposed on one side of the main tank 1, the main tank 1 being connected to a main guide pipe 11, the secondary tank 2 being connected to a secondary guide pipe 21, a liquid mixing structure 3 disposed at the bottom of the secondary tank 2, the main guide pipe 11 and the secondary guide pipe 21 being both connected to a centrifuge device 4, the main guide pipe 11 and the secondary guide pipe 21 being connected to multiple mixing structures 5 disposed at equal intervals, each mixing structure 5 being connected to a spraying system for a greenhouse, and the mixing structure 5 and the centrifuge device 4 being connected to a drive device 6 for transmission; a perforation is opened at the top of the main tank 1, and a sliding piston is disposed inside the main tank 1, the sliding piston being slidably connected to the inner wall of the main tank 1; the main tank 1... Both tank 1 and auxiliary tank 2 have water inlets at their bottoms. The repair agent is delivered through water in auxiliary tank 2 and the liquid mixing structure 3. Then, the liquid mixing structure 3 stirs and mixes the repair agent to form a mixed repair agent with the water in the correct ratio. Then, the driving device 6 drives the centrifugal device 4 to simultaneously carry the water in main tank 1 and the mixed repair agent in auxiliary tank 2 into multiple mixing structures 5 along the main pipe 11 and the auxiliary pipe 21. The water and mixed repair agent are evenly mixed according to the differences in the values ​​of each greenhouse. Finally, the mixture is sprayed into each greenhouse. This can adjust the ratio of the drug required by different varieties of vegetables in the greenhouse, thereby improving efficiency and evenly distributing the mixture.

[0031] The mixing structure 5 includes a mixing hopper 51, which rotates in contact with the outer ring of the stirring blade 53. A cover plate 54 is installed on the top of the mixing hopper 51. The top of the stirring blade 53 passes through the top cover 5423 and is connected to the drive device 6. The cover plate 54 is connected to one end of a symmetrically arranged proportional regulating valve 55. The other ends of the two proportional regulating valves 55 are respectively connected to the main pipe 11 and the auxiliary pipe 21. The opening ratio is adjusted by the two relative proportional regulating valves 55. The centrifugal device 4 pumps out water and mixed repair drugs under the same pressure, so as to adjust the ratio of the drug required by different varieties of greenhouse vegetables. The stirring blade 53 fully mixes the water and the mixed repair drugs, so as to quickly and efficiently adjust and mix the drug and water mixing ratio requirements of different varieties of greenhouse vegetables.

[0032] The centrifuge device 4 includes a centrifuge cover plate 41, the bottom of which is connected to the centrifuge housing 42. The centrifuge housing 42 has symmetrically opened cylindrical grooves, the inner wall of which slides in contact with the outer ring of the centrifuge impeller 43. The bottom of the centrifuge impeller 43 passes through the centrifuge housing 42 and is connected to the drive device 6. The two cylindrical grooves of the centrifuge housing 42 are respectively connected to the main pipe 11 and the auxiliary pipe 21. The top of the centrifuge cover plate 41 is respectively connected to the main pipe 11 and the auxiliary pipe 21. By having the two centrifuge impellers 43 rotate simultaneously at the same speed, the pumping pressure is the same, thus avoiding errors in pressure that could lead to errors in the mixing ratio of water and mixed repair drugs due to different pressures when adjusting the proportioning valve 55.

[0033] The liquid dispensing structure 3 includes a fixed-value motor 31. The output end of the fixed-value motor 31 is connected to the top plate 32, and the top plate 32 is connected to the electric telescopic rod 34. The output end of the fixed-value motor 31 passes through the bottom of the auxiliary tank 2 and is connected to the liquid equalization impeller 35. The liquid equalization impeller 35 is slidably connected to the piston plate 22, and the outer ring of the piston plate 22 is in slidable contact with the inner wall of the auxiliary tank 2. The top of the auxiliary tank 2 is connected to the top cover 23, and the bottom of the auxiliary tank 2 is connected to multiple annularly arranged liquid dispensing devices 33. The liquid dispensing device 33 includes a liquid storage tank 331. The top of liquid tank 331 is connected to auxiliary tank 2. The inner ring of liquid tank 331 is slidably connected to liquid outlet piston 332. The upper end of the inner ring of liquid tank 331 is connected to the outer ring of liquid outlet plate 333. The top of liquid outlet plate 333 is connected to one end of reset elastic element 334. The other end of reset elastic element 334 is connected to one end of connecting rod 335. The other end of connecting rod 335 passes through liquid tank 331 and is connected to the bottom of closing plug 336. A liquid injection threaded hole 337 is opened at the upper end of liquid tank 331. The injection threaded hole 337 is closed by a screw plug. The rotation of the fixed-value motor 31 drives the top plate 32 and the liquid mixing impeller 35 to rotate, thereby ensuring that the input repair drug is fully mixed with water. When a certain drug needs to be prepared, the fixed-value motor 31 rotates by a fixed angle, so that the output end of its electric telescopic rod 34 is aligned with the bottom of the storage tank 331 containing the required drug solution. The extension length of the electric telescopic rod 34 is controlled according to the required drug solution amount. While slowly extending, it pushes the dispensing piston 332 to move. The movement of the dispensing piston 332 causes the drug solution to push open the closing cap 336, thereby allowing the required amount of drug solution to enter the auxiliary tank 2. Then, the closing cap 336, under the action of the reset elastic element 334, closes the dispensing position at the top of the storage tank 331. At the same time, the extension length data of the electric telescopic rod 34 to the storage tank 331 needs to be saved for subsequent use. Finally, the electric telescopic rod 34 resets, thereby accurately controlling the dispensing volume, ensuring no errors, and automating the process.

[0034] The drive unit 6 includes a drive motor 61. The top of the output end of the drive motor 61 is connected to a first gear 65. The first gear 65 meshes with symmetrically arranged second gears 66. Each second gear 66 is connected to a centrifugal impeller 43. By driving the first gear 65 and the symmetrically arranged second gears 66 through the drive motor 61, it is possible to ensure that the two centrifugal impellers 43 rotate simultaneously. This not only saves costs but also ensures the stability of the same rotation speed and avoids errors in the pressure values ​​pumped out by the two centrifugal impellers 43. The output end of the drive motor 61 is connected to a first pulley 62. The first pulley 62 is connected to multiple second pulleys 63 through a transmission belt 64. Each second pulley 63 is connected to a stirring blade 53. The drive motor 61 can not only drive the centrifugal impellers 43 to rotate, but also cause multiple stirring blades 53 to rotate to mix water and mixed repair drugs by driving the first pulley 62, the transmission belt 64, and the multiple second pulleys 63, thereby further reducing costs.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
