Description

Technical Field

[0001] The invention belongs to the technical field of mixed spraying equipment, and in particular relates to a high-efficiency spraying equipment for microbial agents in saline-alkali land. Background Art

[0002] In the field of saline-alkali soil improvement, microbial agents have become an important improvement method due to their characteristics of improving soil structure, regulating microbial communities, and reducing soil salinity.

[0003] Powdered microbial strains are widely used due to their high storage stability, convenient transportation, and ease of mixing with fertilizers. Currently, traditional saline-alkali soil microbial agent spraying equipment mostly uses simple stirring devices. When powdered microbial strains are mixed with water, they easily form agglomerates, resulting in insufficient dissolution and uneven mixing of the agent. During the spraying process, these agglomerates not only clog the nozzles and pipelines, reducing the operational stability of the equipment, but also cause uneven distribution of the agent on the saline-alkali soil surface, affecting the soil improvement effect.

[0004] In addition, the existing equipment lacks an effective mechanism for handling the deposited powder in the tank. After long-term use, the powder of microbial strains at the bottom of the tank clumps and accumulates, further exacerbating the deterioration of mixing quality and the risk of blockage, resulting in frequent equipment maintenance and low operating efficiency. Summary of the Invention

Through the rotation of the rotating rod, the fan blades can rotate to generate suction, thereby sucking in the external liquid medicine, and finally the liquid medicine enters the bottom of the rotating tube and is discharged through the opening at the bottom of the rotating tube, so that the liquid medicine circulates in the spray tank.

[0009] Furthermore, a plurality of scraping rods are fixedly connected to the rotating rod, and one end of the scraping rod away from the rotating rod is in contact with the inner wall of the rotating tube.

[0012] Furthermore, multiple groups of piston cylinders are fixedly connected to the rotating tube, the telescopic ends of the piston cylinders are fixedly connected to the scraper, and the piston cylinders are provided with a liquid inlet pipe and a liquid outlet pipe with a one-way valve. The piston cylinders are used to absorb the powder agglomerates and liquid medicine of the microbial strains deposited at the bottom and discharge them through the liquid outlet pipe.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] Example: Refer to Figure 1-8A high-efficiency spraying device for microbial agents in saline-alkali land includes a spray tank 1, and also includes: a rotating tube 2, which is rotatably connected to the spray tank 1, and the bottom of the rotating tube 2 has an opening; multiple groups of tapered holes 201 are arranged in the rotating tube 2, and the large ends of the tapered holes 201 face outward; multiple groups of curved plates 3 are fixedly connected to the rotating tube 2 at equal intervals, and the concave surfaces of the curved plates 3 face the direction of rotation. Through the rotation of the rotating tube 2, the liquid medicine in the spray tank 1 can flow along the concave curved surface of the curved plates 3 and finally flow to the liquid medicine on the rotating tube 2. The conical hole 201 allows the powder agglomerates of the microbial strains and the liquid medicine to enter the rotating tube 2 together through the large end of the conical hole 201, thereby promoting the dissolution of the powder agglomerates of the microbial strains; the rotating rod 601 is rotatably connected in the rotating tube 2, and the rotating rod 601 is fixedly connected with the fan blade 602. The rotation of the rotating rod 601 can make the fan blade 602 rotate to generate suction, thereby sucking in the external liquid medicine, and finally allowing the liquid medicine to enter the bottom of the rotating tube 2 and be discharged through the opening at the bottom of the rotating tube 2, so that the liquid medicine circulates in the spray tank 1.

[0021] The equipment is securely mounted on the carriage of an agricultural vehicle through a bracket, and the microbial agent liquid is added to the spray tank 1. When the vehicle reaches the saline-alkali land operation area, the motor 101 is started to rotate the rotating tube 2. The curved plate 3 guides the liquid and agglomerates to the conical hole 201 and gathers into the rotating tube 2; the rotating rod 601 cooperates with the fan blades 602 to circulate the liquid and evenly mix the agent.

[0022] During operation, turn on the pump connected to the liquid outlet at the bottom side of the spray tank 1, such as a diaphragm pump, and adjust the power to the tank volume and spraying distance. The pump extracts the mixed liquid and transports it through the pipeline to the spraying components on the vehicle, such as the spray rod and nozzle, to realize the spraying operation of the saline-alkali land microbial agent.

[0023] A gear ring 501 is fixedly connected inside the rotating tube 2, and a transmission gear 1 502 and a transmission gear 2 503 are rotatably connected inside the rotating tube 2. The transmission gear 1 502 is meshed and connected inside the gear ring 501, and the transmission gear 2 503 is meshed and connected with the transmission gear 2 503. Through the clockwise rotation of the gear ring 501, the transmission gear 2 503 can be reversed counterclockwise under the action of the transmission gear 1 502.

[0024] A fixed grinding block 702 is fixedly connected to the bottom opening of the rotating tube 2, and a rotating grinding block 701 matching the fixed grinding block 702 is fixedly connected to the rotating rod 601. There is a grinding gap between the fixed grinding block 702 and the rotating grinding block 701 for grinding the powder agglomerates of the microbial strains.

[0025] A plurality of scraping rods 603 are fixedly connected to the rotating rod 601 , and one end of the scraping rod 603 away from the rotating rod 601 is in contact with the inner wall of the rotating tube 2 .

[0026] During vehicle-mounted operation, the equipment keeps running, and the scraper bar 603 effectively prevents the accumulation of powder in the pipe, ensuring uniform concentration of liquid each time it is pumped. Even during long-term operation, the spraying quality is stable, meeting the continuous spraying needs of large areas of saline-alkali land.

[0027] The rotating tube 2 is slidably connected to a plurality of scrapers 801 between two adjacent sets of arc plates 3 . The scrapers 801 are used to scrape off the powder agglomerates of the microbial strains adhering to the outer wall of the rotating tube 2 .

[0028] Multiple groups of rubber scrapers 801 are connected between the adjacent curved plates 3 via chutes, and the number of the rubber scrapers 801 corresponds to the number of the curved plates 3. The rubber scrapers 801 scrape off the lumps adhering to the outer wall of the rotating tube 2, prevent the lumps from accumulating and falling to the bottom of the tank, ensure the uniform distribution of the powder in the liquid medicine, and improve the mixing quality of the microbial agent.

[0029] A wave convex ring 4 is fixedly connected inside the spray tank 1, and a plurality of scraper blades 801 are fixedly connected with a push rod 802. The end of the push rod 802 away from the scraper blade 801 is slidably connected to the wave surface of the wave convex ring 4. By rotating the rotating tube 2, the plurality of wave convex rings 4 can be moved back and forth up and down under the action of the push rod 802 and the wave convex ring 4.

[0030] Multiple groups of piston cylinders 9 are fixedly connected to the rotating tube 2. The telescopic ends of the piston cylinders 9 are fixedly connected to the scraper 801. The piston cylinders 9 are provided with a liquid inlet pipe 901 and a liquid outlet pipe 902 with a one-way valve. The piston cylinders 9 are used to absorb the powder agglomerates and liquid medicine of the microbial strains deposited at the bottom and discharge them through the liquid outlet pipe 902.

[0031] The scraper 801 moves up and down, driving the piston of the piston cylinder 9 to move, sucking the lumps and liquid medicine deposited at the bottom of the tank through the liquid inlet pipe 901, and then discharging them into the pipe through the liquid outlet pipe 902, stirring the bottom-deposited powder to prevent long-term deposition and agglomeration, allowing the microbial agent to be mixed more fully in the tank and improving the concentration uniformity during spraying.

[0032] The liquid outlet end of the liquid outlet pipe 902 passes through the rotating tube 2 and is located above the grinding gap. The liquid outlet pipe 902 is optimized. The liquid outlet end penetrates the wall of the rotating tube 2 and is located above the grinding gap, above the gap between the fixed grinding block 702 and the rotating grinding block 701. When the piston cylinder 9 discharges liquid through the liquid outlet pipe 902, the liquid medicine and agglomerates fall directly into the grinding gap. The agglomerates are ground and broken by the grinding block, thereby improving the efficiency and effect of powder dissolution, making the microbial agent and liquid medicine mixed more evenly, and ensuring the quality of subsequent spraying.

[0033] The arc-shaped plate 3 is provided with multiple groups of hollow holes 301 .

[0034] When the liquid medicine flows along the curved plate 3, part of the liquid flows out through the hollow hole 301, forming multiple liquid flows. This increases the contact area between the liquid medicine and the air, makes the liquid flow more dispersed, promotes the agglomeration of the powder of the microbial strain and contacts the liquid medicine, helps to increase the dissolution rate, and makes the microbial agent mix more quickly and evenly in the tank, facilitating efficient spraying after pumping the liquid.

[0035] The spray tank 1 is fixedly connected to a motor 101, and the output end of the motor 101 is fixedly connected to the rotating tube 2. Before using the device: the equipment is installed in the carriage of an agricultural vehicle through a fastening bracket to ensure that the spray tank 1 is stable, and the connections of each component are checked: the coupling connection between the motor 101 and the rotating tube 2 is not loose, the rotating rod 601 rotates flexibly in the rotating tube 2, the grinding gap between the fixed grinding block 702 and the rotating grinding block 701 is not blocked by debris, the liquid outlet of the spray tank 1 is sealed with the pump and the spray pipeline, the microbial agent liquid is added to the spray tank 1 through the top liquid filling port, and the liquid filling port sealing cover is closed.

[0036] Then start the motor 101, and the output shaft of the motor 101 rotates, driving the rotating tube 2 to rotate clockwise in the spray tank 1, which can be set to rotate as needed. When the rotating tube 2 rotates, the multiple groups of curved plates 3 fixed thereon rotate synchronously, and the concave surfaces of the curved plates 3 face the direction of rotation. The liquid medicine in the tank is pushed by the curved plates 3, flows along the concave arc trajectory, and gathers toward the rotating tube 2.

[0037] The benefits of this movement are: the curved plate 3 is used to guide the liquid medicine to flow to the rotating tube 2 in an orderly manner, while also driving the possible agglomeration of the powder of the microbial strains to move, thus preventing the powder from settling at the bottom of the tank and preparing for subsequent mixing and grinding.

[0038] During the rotation of the rotating tube 2, the gear transmission ring 501, the transmission gear 1 502, and the transmission gear 2 503 cooperate. If it is to simplify the direct connection, the motor 101 can also drive the rotating rod 601 synchronously or through other transmissions. The rotating rod 601 starts to rotate, and the fan blades 602 on the rod rotate together. The rotation of the fan blades 602 generates suction, and the liquid in the spray tank 1 near the rotating tube 2 is sucked into the rotating tube 2. The liquid flows downward along the inner wall of the rotating tube 2 and flows back to the bottom of the spray tank 1 through the bottom opening, forming a preliminary liquid circulation.

[0039] Advantages: Allow the liquid medicine to continue to flow in the tank, avoid local deposition, promote the contact between the powder and the liquid medicine, and start the dissolution process.

[0040] After the liquid medicine containing the agglomerated powder of the microorganism strains is sucked into the rotating tube 2 by the fan blades 602, it flows to the grinding gap between the fixed grinding block 702 and the rotating grinding block 701 at the bottom opening. As the rotating rod 601 rotates, the rotating grinding block 701 rotates relative to the fixed grinding block 702. When the agglomerated powder of the microorganism strains enters the grinding gap along with the liquid medicine, it is squeezed and ground by the two, and the large agglomerates are broken into fine particles.

[0041] Benefits: Break up the powder agglomerates of microbial strains, increase the contact area between powder and liquid medicine, accelerate the dissolution of powder, avoid agglomerations from clogging subsequent spraying pipelines, and ensure uniform concentration of sprayed microbial agents.

[0042] The scraper rod 603 and the scraper plate 801 work together to enhance cleaning and mixing: Movement of the scraper rod 603: When the rotating rod 601 rotates, the scraper rod 603 on it rotates synchronously. One end of the scraper rod 603 is attached to the inner wall of the rotating tube 2 to scrape off the powder and liquid medicine attached to the inner wall of the rotating tube 2, preventing the powder from accumulating and agglomerating on the tube wall, allowing the liquid medicine to circulate more smoothly and continuously participate in mixing.

[0043] Movement of the scraper 801: The rotating tube 2 rotates, driving the scraper 801 to rotate around the rotating tube 2. At the same time, due to the cooperation between the top rod 802 and the wave convex ring 4, the scraper 801 moves back and forth up and down during the rotation, scraping off the powder agglomerates of microbial strains attached to the outer wall of the rotating tube 2 to prevent the agglomerates from falling and affecting the mixing of the liquid medicine at the bottom of the tank.

[0044] Advantages: The scraper rod 603 and the scraper plate 801 are used to clean the inner and outer walls of the rotating tube 2, thereby reducing the deposition of powder and ensuring the mixing efficiency and uniformity of the liquid medicine.

[0045] As the rotating tube 2 rotates, the piston cylinder 9 moves back and forth with the scraper 801. The piston cylinder 9 extends to the bottom of the tank through the liquid inlet pipe 901 to absorb the powder agglomerates of microbial strains deposited at the bottom of the tank and the liquid medicine, and then discharges them through the outlet of the liquid outlet pipe 902 located above the grinding gap, so that the deposited powder can re-participate in the mixing and grinding process.

[0046] Benefits: Activate the powder deposited at the bottom of the tank to prevent long-term sedimentation and agglomeration that is difficult to dissolve, further improve the mixing uniformity of the liquid medicine, and allow the microbial agent to fully dissolve.

[0047] When the equipment is driven by a vehicle to the saline-alkali land operation area, the pump connected to the liquid outlet of the spray tank 1, such as a diaphragm pump, is turned on. After the pump is started, the fully mixed and ground microbial agent liquid in the tank is extracted and transported through the pipeline to the spraying components carried by the vehicle, such as the spray rod and the nozzle. The liquid is atomized or sprayed at high pressure through the nozzle and evenly sprayed onto the surface of the saline-alkali land.

[0048] Advantages: With the help of vehicle-mounted mobility, large areas of saline-alkali land can be efficiently covered; the liquid medicine that is fully mixed and ground by the equipment is evenly distributed after spraying, which can better improve the soil environment of saline-alkali land and enhance the effect of microbial agents.

[0049] The present invention can effectively achieve efficient breaking of bacterial agent lumps through the coordinated movement of components such as the rotating tube 2, the curved plate 3, and the fan blades 602, so that the medicinal liquid is evenly mixed and circulated, avoiding the agglomeration that occurs when powdered microbial strains are put into water, thereby solving the problems of poor mixing and easy clogging, improving the quality and operating efficiency of saline-alkali land bacterial agent spraying, and facilitating the use of saline-alkali land soil improvement.
