Description

Technical Field

[0001] This utility model belongs to the field of agricultural mixing machinery technology, and relates to a proportioning and mixing device, particularly a proportioning and mixing device for foliar fungicide raw materials for the prevention and control of anthracnose in tea trees. Background Technology

[0002] Anthracnose is a common fungal disease in tea cultivation, affecting both tea yield and quality. Currently, foliar fungicides are one of the more effective control measures. However, the preparation of foliar fungicides involves the accurate proportioning and thorough mixing of various liquid raw materials, powdered raw materials, and liquid excipients. Therefore, the performance of the raw material mixing device directly affects the effectiveness of the fungicide.

[0003] In the prior art, such as some mixing devices disclosed in Chinese patent documents, although they can achieve a certain degree of raw material mixing function, they often have the following shortcomings: when powdered raw materials are fed, dust is easily generated and escapes, polluting the working environment and causing material loss; the proportion of liquid raw materials is not accurate enough, making it difficult to achieve step-by-step quantitative control; the mixing device has a single stirring method, which easily creates stirring dead zones, resulting in uneven material mixing and affecting the quality stability of the microbial agent.

[0004] Furthermore, existing mixing devices lack effective fixation of the tank during mixing, making it prone to shaking and displacement, affecting mixing safety and efficiency. After mixing, the tank is inconvenient to handle, typically requiring manual transport, resulting in low operational efficiency. Additionally, residual liquid can easily drip and contaminate the work area when the mixing lid is raised, and the overall device's height is inconvenient, impacting ease of use and maintenance efficiency. Therefore, there is an urgent need for a foliar fungicide mixing device for tea anthracnose control that can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a foliar fungicide raw material mixing device for the prevention and control of anthracnose in tea trees. The technical problem to be solved by this utility model is: how to achieve accurate and sequential closed conveying, efficient mixing and temperature-controlled heating of powdered and liquid raw materials in stages, while solving problems such as dust leakage during feeding, tank shaking during mixing and residual liquid dripping and polluting the environment when the lifting and lowering stirring cover is raised.

[0006] The objective of this utility model can be achieved through the following technical solutions: A foliar fungicide mixing device for controlling anthracnose in tea trees includes a main frame with a ladder at the rear. On the lower inner plate of the main frame are a powder adding mechanism, a lifting and stirring cover mechanism, a tank placement seat, a tank clamping mechanism, and a liquid adding mechanism. The powder adding mechanism is located on the inner left side of the main frame, while the lifting and stirring cover mechanism, tank clamping mechanism, and liquid adding mechanism are located on the inner right side of the main frame, arranged sequentially from front to back. The tank placement seat is located inside the tank clamping mechanism and directly below the lifting and stirring cover mechanism. A stirring tank is placed on the upper end of the tank placement seat, and the tank clamping mechanism holds the stirring tank outside. The lifting and stirring cover mechanism is located above the stirring tank. A screw conveyor is rotatably connected to the lower end of the powder adding mechanism, and a quick-connect pipe is provided between the screw conveyor and the lifting and stirring cover mechanism. A proportioning and initial mixing mechanism is located on the upper plate of the main frame. Both the proportioning and initial mixing mechanism and the liquid adding mechanism are connected to the lifting and stirring cover mechanism via pipes.

[0007] The working principle of this utility model is as follows: the mixing tank is placed above the tank placement seat. During operation, the lifting mixing cover mechanism descends and extends to cover the mixing tank set on the tank placement seat. The tank clamping mechanism clamps and fixes the mixing tank to ensure that the mixing tank remains stable during the mixing process.

[0008] First, the liquid raw materials of the foliar fungicide for the prevention and control of anthracnose in tea trees that need to be pre-mixed are initially mixed through the proportioning and mixing mechanism, while the powdered raw materials are added to the powder addition mechanism for later use.

[0009] The initial mixing mechanism transports the pre-mixed liquid materials of the foliar fungicide for controlling anthracnose in tea trees through pipelines to the lifting and mixing cover mechanism; the powder addition mechanism transports the powder to the lifting and mixing cover mechanism via a screw conveyor at its lower end. Simultaneously, the liquid addition mechanism also transports the liquid adjuvants of the foliar fungicide for controlling anthracnose in tea trees to the lifting and mixing cover mechanism through pipelines.

[0010] At this point, the powder, initial mixed liquid, and auxiliary materials are all fed into the mixing tank via the lifting and stirring cover mechanism. Subsequently, the lifting and stirring cover mechanism starts the stirring action to perform final mixing of the materials in the tank, thereby achieving accurate proportioning and uniform mixing of the foliar fungicide raw materials.

[0011] After mixing is complete, the screw conveyor rotates and disconnects from the lifting and stirring cover mechanism. The lifting and stirring cover mechanism rises and completely separates from the mixing tank. The tank clamping mechanism releases the clamping and fixing of the mixing tank. The mixing tank can then be manually removed from the tank placement seat using a forklift for easy material handling or replacement.

[0012] The entire device can be operated up and down with the aid of a ladder frame, enabling convenient feeding, proportioning, mixing and discharging processes.

[0013] The proportioning and initial mixing mechanism includes an initial mixing tank and several mounting columns. The initial mixing tank and the mounting columns are fixed on the upper plate of the main frame. The mounting columns are located on the outer periphery of the initial mixing tank. Each mounting column is equipped with a feeding hopper. Several mounting columns are equipped with a stirring tank and an electric stirring frame II. The stirring frame of the electric stirring frame II extends into the interior of the stirring tank. The stirring tank and the initial mixing tank are connected by a pipe. The stirring tank and the feeding hopper on the same mounting column are connected by a pipe. The remaining feeding hoppers are connected to the initial mixing tank by pipes. One of the mounting columns is equipped with an electric stirring frame I. The stirring frame of the electric stirring frame I extends into the interior of the initial mixing tank. All pipes and the liquid outlet of the initial mixing tank are equipped with a drain valve.

[0014] The proportioning and initial mixing mechanism is used to pre-proportion and initially mix various liquid raw materials of foliar fungicide for the prevention and control of anthracnose in tea trees.

[0015] During operation, each liquid raw material is fed into its corresponding hopper. Some of the raw materials from the hoppers first enter the corresponding agitator tank, where they are stirred by an electric agitator to facilitate dispensing. The stirred material is then piped into the primary mixing tank. The remaining raw materials from the hoppers are directly piped into the primary mixing tank.

[0016] After all liquid raw materials are collected in the primary mixing tank, an electric agitator is used to thoroughly mix each liquid raw material to form a preliminary mixture.

[0017] Each pipeline and the outlet of the primary mixing tank is equipped with a drain valve to control the flow and shut-off of materials at each stage. Finally, the liquid material that has completed the initial mixing is discharged through the outlet of the primary mixing tank and transported to the subsequent work station.

[0018] The powder adding mechanism includes a support frame and a dust collection filter box. The support frame and the dust collection filter box are fixed on the inner lower plate of the main frame in a front-to-back arrangement. The upper end of the support frame is provided with a powder discharge valve hopper. The upper end of the powder discharge valve hopper is flush with the upper plate of the main frame. The upper end of the powder discharge valve hopper is provided with a feeding hood. A dust collection pipe is provided between the side of the feeding hood and the dust collection filter box. The discharge end of the powder discharge valve hopper is provided with a rotary joint. A discharge valve is provided between the rotary joint and the feed end of the screw conveyor.

[0019] With the above structure, the powder adding mechanism is used to quantitatively and stably transport powdered raw materials to subsequent work stations.

[0020] During operation, the operator feeds the powdered raw materials into the powder discharge valve hopper through the feeding hood for temporary storage. A discharge valve is installed between the rotary joint at the discharge end of the powder discharge valve hopper and the feed end of the screw conveyor. By controlling the opening and closing and the degree of opening of the discharge valve, the powder can be quantitatively fed.

[0021] The powder falls into the screw conveyor through the discharge valve, and the screw conveyor transports the powder in a sealed manner to the lifting and stirring cover mechanism to complete the addition of the powder.

[0022] During the feeding process, the side of the feeding hood is connected to a dust collection filter box via a dust suction pipe. The dust collection filter box provides negative pressure suction to promptly extract and filter the dust generated during feeding, preventing dust from escaping and maintaining a clean working environment.

[0023] After mixing is complete, manually disconnect the screw conveyor from the lifting and stirring cover mechanism, manually push the screw conveyor so that the discharge valve rotates around the rotary joint, move the screw conveyor away, and the lifting and stirring cover mechanism rises up, completely separating from the mixing tank, so that the tank placement seat can slide out.

[0024] The liquid addition mechanism includes several liquid hopper columns, which are all fixed to the rear of the inner side of the lower plate of the main frame. The upper end of the liquid hopper columns is provided with a liquid mixing hopper, and the liquid mixing hopper is provided with several liquid inlet pipes, which are respectively connected to an external liquid injection pump. One of the liquid hopper columns is provided with a rotatable horizontal liquid receiving plate.

[0025] Using the above structure, the liquid material addition mechanism is used to quantitatively deliver liquid additives to subsequent workstations as needed. During operation, an external injection pump sends liquid additives through various inlet pipes into the liquid mixing hopper for temporary storage. The liquid mixing hopper then transports the liquid additives to the lifting and stirring cover mechanism via flexible connecting pipes, completing the addition of the liquid additives.

[0026] When the lifting and stirring cover mechanism is raised, the liquid receiving tray on the liquid hopper column can be rotated to the bottom of the lifting and stirring cover mechanism to catch any residual dripping liquid from the lifting and stirring cover mechanism, preventing liquid from dripping and contaminating the working environment; when not in use, the liquid receiving tray can be rotated and retracted to save space.

[0027] The tank clamping mechanism includes a clamping base frame, which is fixed to the middle of the inner lower plate of the main frame. Side clamping rod 1 and side clamping rod 2 are respectively hinged to the left and right sides of the clamping base frame. A manual locking rod is hinged between the clamping base frame and side clamping rod 1, and an electric push rod is hinged between the clamping base frame and side clamping rod 2. A limiting frame is provided at the right end of the clamping base frame. Side clamping rod 1, the limiting frame and side clamping rod 2 form a U-shaped clamping group that opens to the right. The tank placement seat is located directly below the U-shaped clamping group. The tank placement seat is divided into three parts: front, middle and rear, with two clearance areas in the middle.

[0028] With the above structure, the tank clamping mechanism is used to clamp and fix the mixing tank during the mixing process to prevent it from shifting or shaking, and to ensure safe and stable mixing.

[0029] During operation, the mixing tank is placed on the tank mounting base, and the clamping base is fixed to the main frame, serving as the installation foundation for the entire mechanism.

[0030] During clamping, the electric push rod pulls the second side clamping rod to swing towards the tank body, cooperating with the first side clamping rod and the limiting bracket to clamp and fix the mixing tank from three directions. The manual locking rod can be used to manually lock the position of the first side clamping rod, enhancing clamping reliability and preventing loosening during mixing.

[0031] When the clamping is released, the electric push rod is pushed back, causing the two side clamping rods to swing outward, releasing the mixing tank. At this time, the forklift forks are inserted into the two clearance areas of the tank placement seat to remove the mixing tank from the tank placement seat.

[0032] The limiting frame not only serves as one side of the clamping assembly but also acts as a positioning element to ensure the accurate placement of the mixing tank components.

[0033] The lifting and stirring cover mechanism includes a lifting base frame, which is fixed to the front of the inner side of the main frame's lower plate. An electric lifting screw is installed at the upper end of the lifting base frame, and a lifting seat is fixed to the slide of the electric lifting screw. A stirring motor is fixed to the upper end of the lifting seat, and a tank cover is fixed to the lower end of the lifting seat. The output shaft of the stirring motor extends downwards through the tank cover. An mounting cylinder and a gear disc are fixed to the output shaft of the stirring motor. The gear disc is located inside the mounting cylinder. Two symmetrically arranged rotating stirring frames are rotatably mounted on the mounting cylinder. A transmission gear is fixed to the rotating shaft of each rotating stirring frame. The transmission gear is located inside the mounting cylinder and meshes with the gear disc. Two symmetrically arranged scrapers are fixed to the outer side of the mounting cylinder. The two scrapers and the two rotating stirring frames are arranged in a cross shape. A quick-connect pipe is installed between the discharge end of the screw conveyor and the tank cover. A flexible connecting pipe is installed between the discharge valve of the primary mixing tank and the tank cover. A flexible connecting pipe is also installed between the liquid mixing hopper and the tank cover.

[0034] With the above structure, the lifting and stirring cover mechanism is used to achieve the functions of sealing the mixing tank, stirring and mixing, and introducing materials.

[0035] Lifting action: The electric lifting screw drives the lifting seat to move up and down along the lifting base frame, thereby causing the tank cover fixed at the lower end of the lifting seat to rise or fall. During the mixing process, the tank cover falls and seals the opening of the mixing tank; after mixing is completed, the tank cover rises and leaves the mixing tank for easy removal.

[0036] Material introduction: The tank cover is connected to the discharge end of the screw conveyor, the drain valve of the primary mixing tank and the liquid mixing hopper through quick pipe connectors, flexible connecting pipes, etc., so that powder, primary mixed liquid and liquid auxiliary materials are all collected into the mixing tank through the tank cover.

[0037] After mixing, manually disconnect the quick connector from the tank cover, and manually push the screw conveyor so that the discharge valve rotates around the rotary joint, moving the discharge end of the screw conveyor away from the top of the tank cover.

[0038] Stirring action: The stirring motor starts, and its output shaft drives the mounting cylinder and gear disc to rotate synchronously. The gear disc meshes with the transmission gears on the shafts of the two rotating stirring frames, driving the two rotating stirring frames to rotate on the mounting cylinder and stir and mix the materials in the tank. At the same time, two scrapers fixed to the outer side of the mounting cylinder rotate with the mounting cylinder to scrape off the material adhering to the inner wall of the mixing tank, preventing the material from sticking to the wall and improving the uniformity of mixing.

[0039] The two scrapers and two rotating stirring racks are arranged in a cross shape, so that the stirring and scraping actions do not interfere with each other and work together to complete efficient mixing.

[0040] The mixing tank includes a mixing tank body, which is a double-layered tank. The mixing tank body is equipped with several heating rods inside. The liquid outlet end of the mixing tank body is equipped with a discharge valve. The lower end of the mixing tank body is equipped with several circumferentially distributed support legs, which are placed on the upper end of the tank body placement seat. The mixing tank body is equipped with a temperature sensor that extends into its interior.

[0041] With the above structure, the mixing tank serves as the final mixing container, used to hold powder, initial mixed liquid and liquid auxiliary materials, and completes the final uniform mixing with the cooperation of the lifting mixing cover mechanism.

[0042] During operation, the mixing tank body is stably positioned on top of the tank stand by evenly distributed support legs at its lower circumference, ensuring stability during mixing. The mixing tank body has a double-layer structure with excellent thermal insulation properties. Several heating rods installed inside heat the materials during mixing, and a temperature sensor detects the heating temperature to meet the temperature control requirements for preparing foliar fungi agents, promoting thorough mixing or improving dissolution efficiency.

[0043] After mixing, the finished product is discharged through the discharge valve at the liquid outlet end of the mixing tank, thus completing the discharge process.

[0044] Compared with existing technologies, this foliar fungicide mixing device for the prevention and control of anthracnose in tea trees has the following advantages: The system utilizes a pre-mixing mechanism, a powder addition mechanism, and a liquid addition mechanism to achieve accurate proportioning and independent conveying of various raw materials. The powder addition mechanism, in conjunction with a dust extraction filter box, effectively prevents dust escape, ensuring a clean operating environment. The tank clamping mechanism and the lifting mixing cover mechanism work together to stably clamp and seal the tank, ensuring a safe and leak-free mixing process. The mixing motor, along with the rotating mixing frame and scraper, are arranged in a cross shape to achieve efficient, dead-angle-free mixing and prevent material from sticking to the walls. The double-layered tank, combined with a heating rod and temperature sensor, meets temperature-controlled mixing requirements. The finished product is discharged through a discharge valve, and the mixing tank can be removed as a whole by forklift. The drip tray and ladder further enhance ease of use and maintenance.

[0054] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0055] like Figures 1-8As shown, this foliar fungicide mixing device for controlling anthracnose in tea trees includes a main frame 1. A ladder frame 4 is provided on the rear side of the main frame 1. A powder adding mechanism 3, a lifting and stirring cover mechanism 6, a tank placement seat 40, a tank clamping mechanism 8, and a liquid adding mechanism 9 are provided on the inner lower plate of the main frame 1. The powder adding mechanism 3 is located on the inner left side of the main frame 1, and the lifting and stirring cover mechanism 6, the tank clamping mechanism 8, and the liquid adding mechanism 9 are located on the inner right side of the main frame 1, arranged sequentially from front to back. The tank placement seat 40 is located on the tank clamping mechanism 8. Inside the tank and directly below the lifting and stirring cover mechanism 6, the tank body placement seat 40 has a stirring tank 7 placed on its upper end. The tank body clamping mechanism 8 clamps the outside of the stirring tank 7. The lifting and stirring cover mechanism 6 is located on the upper part of the stirring tank 7. The lower end of the powder adding mechanism 3 is rotatably connected to a screw conveyor 2. A quick pipe connector is provided between the screw conveyor 2 and the lifting and stirring cover mechanism 6. The upper plate of the main frame 1 is provided with a proportioning and initial mixing mechanism 5. Both the proportioning and initial mixing mechanism 5 and the liquid adding mechanism 9 are connected to the lifting and stirring cover mechanism 6 through pipes.

[0056] When the mixing tank 7 is placed above the tank placement seat 40, the lifting mixing cover mechanism 6 descends and extends to cover the mixing tank 7 set on the tank placement seat 40 during operation. The tank clamping mechanism 8 clamps and fixes the mixing tank 7 to ensure that the mixing tank 7 remains stable during the mixing process.

[0057] First, the liquid raw materials of the leaf fungicide for the prevention and control of anthracnose in tea trees that need to be pre-mixed are initially mixed through the proportioning and mixing mechanism 5, while the powdered raw materials are added to the powder addition mechanism 3 for later use.

[0058] The initial mixing mechanism 5 transports the pre-mixed liquid materials of the foliar fungicide for controlling anthracnose in tea trees to the lifting and mixing cover mechanism 6 via pipelines; the powder addition mechanism 3 transports the powder to the lifting and mixing cover mechanism 6 via the screw conveyor 2 at its lower end. At the same time, the liquid addition mechanism 9 also transports the liquid adjuvants of the foliar fungicide for controlling anthracnose in tea trees to the lifting and mixing cover mechanism 6 via pipelines.

[0059] At this point, the powder, initial mixed liquid, and auxiliary materials are all fed into the mixing tank 7 via the lifting and stirring cover mechanism 6. Subsequently, the lifting and stirring cover mechanism 6 starts the stirring action to perform final mixing of the materials in the tank, thereby achieving accurate proportioning and uniform mixing of the foliar fungicide raw materials.

[0060] After mixing is completed, the screw conveyor 2 rotates and disconnects from the lifting and stirring cover mechanism 6. The lifting and stirring cover mechanism 6 rises and completely separates from the mixing tank 7. The tank clamping mechanism 8 releases the clamping and fixing of the mixing tank 7. The mixing tank 7 can be manually removed from the tank placement seat 40 by a forklift for easy material removal or replacement.

[0061] The entire device can be operated up and down with the aid of the ladder frame 4, enabling convenient feeding, proportioning, mixing and discharging processes.

[0062] The proportioning and initial mixing mechanism 5 includes an initial mixing tank 15 and several mounting columns 10. The initial mixing tank 15 and several mounting columns 10 are fixed on the upper plate of the main frame 1. The several mounting columns 10 are located on the outer periphery of the initial mixing tank 15. Each mounting column 10 is equipped with a feeding hopper 11. Each of the mounting columns 10 is equipped with a stirring tank 14 and an electric stirring frame 2 13. The stirring frame of the electric stirring frame 2 13 extends into the interior of the stirring tank 14. The stirring tank 14 is connected to the initial mixing tank 15 through a pipe. The stirring tank 14 is connected to the feeding hopper 11 on the same mounting column 10 through a pipe. The remaining feeding hoppers 11 are connected to the initial mixing tank 15 through pipes. One of the mounting columns 10 is equipped with an electric stirring frame 12. The stirring frame of the electric stirring frame 12 extends into the interior of the initial mixing tank 15. All pipes and the liquid outlet of the initial mixing tank 15 are equipped with a drain valve.

[0063] The proportioning and initial mixing unit 5 is used to pre-proportion and initially mix various liquid raw materials of the foliar fungicide for the prevention and control of anthracnose in tea trees.

[0064] During operation, each liquid raw material is fed into its corresponding feeding hopper 11. Some of the raw materials in the feeding hopper 11 first enter the corresponding stirring tank 14, where they are stirred by an electric stirring frame 13 to facilitate feeding. The stirred material is then sent to the primary mixing tank 15 through a pipeline. The remaining raw materials in the feeding hopper 11 are directly sent to the primary mixing tank 15 through a pipeline.

[0065] After all liquid raw materials are collected into the primary mixing tank 15, the electric stirring rack 12 thoroughly mixes each liquid raw material to form a preliminary mixture.

[0066] Each pipeline and the outlet of the primary mixing tank 15 is equipped with a drain valve to control the flow and shut-off of materials at each stage. Finally, the liquid material that has completed the initial mixing is discharged through the outlet of the primary mixing tank 15 and transported to the subsequent work station.

[0067] The powder adding mechanism 3 includes a support frame 19 and a dust collection filter box 20. The support frame 19 and the dust collection filter box 20 are fixed on the inner lower plate of the main frame 1 in a front-to-back arrangement. The upper end of the support frame 19 is provided with a powder discharge valve hopper 17. The upper end of the powder discharge valve hopper 17 is flush with the upper plate of the main frame 1. The upper end of the powder discharge valve hopper 17 is provided with a feeding hood 16. A dust collection pipe 18 is provided between the side of the feeding hood 16 and the dust collection filter box 20. The discharge end of the powder discharge valve hopper 17 is provided with a rotating joint. A discharge valve is provided between the rotating joint and the feed end of the screw conveyor 2.

[0068] The powder addition mechanism 3 is used to quantitatively and stably transport powdered raw materials to subsequent work stations.

[0069] During operation, the operator temporarily stores the powdered raw materials into the powder discharge valve hopper 17 through the feeding hood 16. A discharge valve is provided between the rotary joint at the discharge end of the powder discharge valve hopper 17 and the feed end of the screw conveyor 2. By controlling the opening and closing and the degree of opening of the discharge valve, the powder can be quantitatively fed.

[0070] The powder falls into the screw conveyor 2 through the discharge valve, and the screw conveyor 2 conveys the powder in a sealed manner to the lifting and stirring cover mechanism 6 to complete the addition of powder.

[0071] During the feeding process, the side of the feeding hood 16 is connected to the dust collection filter box 20 through the dust collection pipe 18. The dust collection filter box 20 provides negative pressure suction to timely extract and filter the dust generated during feeding, prevent dust from escaping, and keep the working environment clean.

[0072] After mixing is complete, manually disconnect the screw conveyor 2 from the lifting and stirring cover mechanism 6, manually push the screw conveyor 2 so that the unloading valve rotates around the rotary joint, move the screw conveyor 2 away, and lift and stir cover mechanism 6 rises up, completely leaving the mixing tank 7, so that the tank placement seat 40 can slide out.

[0073] The liquid addition mechanism 9 includes several liquid hopper columns 23, which are all fixed to the rear of the inner side of the lower plate of the main frame 1. The upper end of the liquid hopper columns 23 is provided with a liquid mixing hopper 21, and the liquid mixing hopper 21 is provided with several liquid inlet pipes 22. The liquid inlet pipes 22 are all connected to an external liquid injection pump. One of the liquid hopper columns 23 is provided with a rotatable horizontal liquid receiving plate 24.

[0074] The liquid material adding mechanism 9 is used to quantitatively deliver liquid additives to subsequent workstations as needed. During operation, an external injection pump sends liquid additives through each inlet pipe 22 into the liquid mixing hopper 21 for collection and temporary storage. The liquid mixing hopper 21 then delivers the liquid additives to the lifting and stirring cover mechanism 6 via a flexible connecting pipe, completing the addition of the liquid additives.

[0075] When the lifting and stirring cover mechanism 6 is raised, the liquid receiving tray 24 set on the liquid column 23 can be rotated to the bottom of the lifting and stirring cover mechanism 6 to receive the residual dripping liquid from the lifting and stirring cover mechanism 6, preventing the liquid from dripping and contaminating the working environment; when not in use, the liquid receiving tray 24 can be rotated and folded up to save space.

[0076] The tank clamping mechanism 8 includes a clamping base 26, which is fixed to the middle of the inner lower plate of the main frame 1. Side clamping rod 1 25 and side clamping rod 20 are respectively hinged to the left and right sides of the clamping base 26. A manual locking rod 27 is hinged between the clamping base 26 and the side clamping rod 1 25. An electric push rod 29 is hinged between the clamping base 26 and the side clamping rod 20. A limiting frame 28 is provided at the right end of the clamping base 26. The side clamping rod 1 25, the limiting frame 28 and the side clamping rod 20 form a U-shaped clamping group that opens to the right. The tank placement seat 40 is located directly below the U-shaped clamping group. The tank placement seat 40 is divided into three parts: front, middle and rear, with two clearance areas in the middle.

[0077] The tank clamping mechanism 8 is used to clamp and fix the mixing tank 7 during the mixing process to prevent it from shifting or shaking, and to ensure safe and stable mixing.

[0078] During operation, the mixing tank 7 is placed on the tank placement seat 40, and the clamping base 26 is fixed on the main frame 1, serving as the installation foundation for the entire mechanism.

[0079] During clamping, the electric push rod 29 pulls the second side clamping rod 30 to swing towards the tank body, which, together with the first side clamping rod 25 and the limiting bracket 28, clamps and fixes the mixing tank 7 from three directions. The manual locking rod 27 can be used to manually lock the position of the first side clamping rod 25, enhancing the clamping reliability and preventing loosening during the mixing process.

[0080] When the clamping is released, the electric push rod 29 is pushed back, causing the side clamping rod 30 to swing outward, releasing the mixing tank 7. At this time, the forklift forks are inserted into the two clearance areas of the tank placement seat 40 respectively, and the mixing tank 7 is removed from the tank placement seat 40.

[0081] The limiting frame 28 not only serves as one side of the clamping assembly, but also plays a positioning role to ensure that the mixing tank 7 is placed in the correct position.

[0082] The lifting and stirring cover mechanism 6 includes a lifting base frame 31, which is fixed to the front of the lower plate inside the main frame 1. An electric lifting screw 32 is provided at the upper end of the lifting base frame 31. A lifting seat 33 is fixed on the slide of the electric lifting screw 32. A stirring motor 34 is fixed at the upper end of the lifting seat 33, and a tank cover 35 is fixed at the lower end of the lifting seat 33. The output shaft of the stirring motor 34 extends downward through the tank cover 35. An mounting cylinder 36 and a gear disk 37 are fixed on the output shaft of the stirring motor 34. The gear disk 37 is located inside the mounting cylinder 36. The mounting cylinder 36 rotates upwards... The device is equipped with two symmetrically arranged rotating stirring frames 39. A transmission gear is fixed on the rotating shaft of the rotating stirring frame 39. The transmission gear is located inside the mounting cylinder 36 and meshes with the gear disk 37. Two symmetrically arranged scraper frames 38 are fixed on the outer side of the mounting cylinder 36. The two scraper frames 38 and the two rotating stirring frames 39 are arranged in a cross shape. A quick-connect pipe is set between the discharge end of the screw conveyor 2 and the tank cover 35. A flexible connecting pipe is provided between the drain valve of the primary mixing tank 15 and the tank cover 35. A flexible connecting pipe is provided between the liquid mixing hopper 21 and the tank cover 35.

[0083] The lifting and lowering stirring cover mechanism 6 is used to cover the stirring tank 7, stir and mix the materials, and introduce them into the tank.

[0084] Lifting action: The electric lifting screw 32 drives the lifting seat 33 to move up and down along the lifting base 31, thereby causing the tank cover 35 fixed to the lower end of the lifting seat 33 to rise or fall. During the stirring operation, the tank cover 35 falls and seals the opening of the stirring tank 7; after the mixing is completed, the tank cover 35 rises and leaves the stirring tank 7 for easy removal of the tank.

[0085] Material introduction: The tank cover 35 is connected to the discharge end of the screw conveyor 2, the drain valve of the primary mixing tank 15 and the liquid mixing hopper 21 through quick pipe connectors and flexible connecting pipes, so that the powder, primary mixed liquid and liquid auxiliary materials are all fed into the mixing tank 7 through the tank cover 35.

[0086] After mixing, manually disconnect the quick connector from the tank cover 35, and manually push the screw conveyor 2 so that the discharge valve rotates around the rotary joint, moving the discharge end of the screw conveyor 2 away from the top of the tank cover 35.

[0087] Stirring action: The stirring motor 34 starts, and its output shaft drives the mounting cylinder 36 and gear disk 37 to rotate synchronously. The gear disk 37 meshes with the transmission gears on the shafts of the two rotating stirring frames 39, driving the two rotating stirring frames 39 to rotate on the mounting cylinder 36, stirring and mixing the materials in the tank. At the same time, the two scrapers 38 fixed to the outer side of the mounting cylinder 36 rotate with the mounting cylinder 36 to scrape off the material adhering to the inner wall of the mixing tank 7, preventing the material from sticking to the wall and improving the uniformity of mixing.

[0088] The two scraper frames 38 and the two rotating stirring frames 39 are arranged in a cross shape, so that the stirring and scraping actions do not interfere with each other and work together to complete efficient mixing.

[0089] The mixing tank component 7 includes a mixing tank body 41, which is a double-layered tank. The mixing tank body 41 is equipped with several heating rods 42 inside. The liquid outlet end of the mixing tank body 41 is equipped with a discharge valve 43. The lower end of the mixing tank body 41 is equipped with several circumferentially distributed support legs 44, which are placed on the upper end of the tank body placement seat 40. The mixing tank body 41 is equipped with a temperature sensor that extends into its interior.

[0090] The mixing tank 7 serves as the final mixing container, used to hold powder, initial mixed liquid and liquid auxiliary materials, and completes the final uniform mixing with the cooperation of the lifting mixing cover mechanism 6.

[0091] During operation, the mixing tank body 41 is stably positioned on top of the tank stand 40 via evenly distributed support legs 44 at its lower circumference, ensuring the tank remains stable during mixing. The mixing tank body 41 has a double-layer tank structure with good heat insulation performance. Several heating rods 42 installed inside can heat the materials during mixing, and a temperature sensor detects the heating temperature to meet the temperature control requirements during the preparation of foliar fungi agents, promoting thorough mixing of materials or improving dissolution efficiency.

[0092] After mixing, the finished product is discharged through the discharge valve 43 at the liquid outlet end of the mixing tank body 41, thus completing the discharge.

[0093] The working principle of this utility model: 1. Preparation First, a forklift is used to stably place the mixing tank 7 onto the tank placement seat 40 via its evenly distributed support legs 44 at its lower end. The tank placement seat 40 is located directly below the U-shaped clamping assembly of the tank clamping mechanism 8. Then, the tank clamping mechanism 8 is activated: the electric push rod 29 pulls the second side clamping rod 30 to swing towards the tank, which, together with the first side clamping rod 25 and the limiting bracket 28, clamps and fixes the mixing tank 7 from three directions. The manual locking rod 27 can manually lock the first side clamping rod 25 to enhance reliability and ensure that the tank remains stable and does not shift during the mixing process.

[0094] Simultaneously, the electric lifting screw 32 of the lifting and stirring cover mechanism 6 drives the lifting seat 33 to descend along the lifting base frame 31, causing the tank cover 35 fixed at the lower end of the lifting seat 33 to descend and seal the tank opening of the stirring tank 7. At this time, the discharge end of the screw conveyor 2 is connected to the tank cover 35 through a quick-connect pipe, and the liquid outlet of the primary mixing tank 15 of the proportioning and primary mixing mechanism 5 and the liquid mixing hopper 21 of the liquid addition mechanism 9 are also connected to the tank cover 35 through flexible connecting pipes, completing the material introduction preparation.

[0095] 2. Pre-proportioning and initial mixing of liquid raw materials Multiple liquid raw materials are pre-proportioned and initially mixed using the proportioning and initial mixing mechanism 5. Each liquid raw material is fed into its corresponding hopper 11. Some of the raw materials from hopper 11 first enter the corresponding stirring tank 14, where they are pre-mixed by the electric stirring frame 13, and then sent to the initial mixing tank 15 via pipeline. The remaining raw materials from hopper 11 are directly sent to the initial mixing tank 15 via pipeline. After all liquid raw materials are collected in the initial mixing tank 15, they are thoroughly mixed by the electric stirring frame 12 to form a preliminary mixture. The flow of materials is controlled by the drain valves at the outlet of each pipeline and the initial mixing tank 15. The pre-mixed liquid material is discharged from the outlet of the initial mixing tank 15 and transported to the tank cover 35 via a flexible connecting pipeline.

[0096] 3. Addition of powdered raw materials Powdered raw materials are quantitatively conveyed through the powder adding mechanism 3. Operators temporarily store the powder in the powder discharge valve hopper 17 via the feeding hood 16, and quantitative feeding is achieved by controlling the opening and closing of the discharge valve. The powder falls through the discharge valve into the screw conveyor 2, which then conveys it in a sealed manner to the tank cover 35. During the feeding process, the dust collection filter box 20 provides negative pressure suction through the dust collection pipe 18 to promptly extract and filter the dust generated at the feeding hood 16, preventing dust from escaping.

[0097] 4. Addition of liquid excipients The liquid material addition mechanism 9 delivers liquid auxiliary materials as needed. An external injection pump sends the liquid auxiliary materials into the liquid mixing hopper 21 through each inlet pipe 22 for collection and temporary storage, and then delivers them to the tank cover 35 through a flexible connection pipeline.

[0098] 5. Final Mixing Powder, initial mixed liquid, and liquid additives are fed into the mixing tank 7 via the tank cover 35. Then, the mixing motor 34 starts, and its output shaft drives the mounting cylinder 36 and gear disc 37 to rotate synchronously. The gear disc 37 meshes with the transmission gears on the shafts of the two rotating mixing frames 39, driving the two rotating mixing frames 39 to rotate and thoroughly mix the materials inside the tank. Simultaneously, two scrapers 38 fixed to the outer side of the mounting cylinder 36 rotate with the mounting cylinder 36, scraping off the adhering material on the inner wall of the mixing tank body 41 to prevent sticking. The two scrapers 38 and the two rotating mixing frames 39 are arranged in a cross shape, ensuring that the mixing and scraping actions are coordinated and efficient.

[0099] During the mixing process, several heating rods 42 installed inside the mixing tank body 41 can heat the materials to meet the preparation temperature requirements and promote mixing and dissolution. The double-layer tank structure of the mixing tank body 41 provides good thermal insulation performance.

[0100] 6. Discharging and removing from the tank Subsequently, manually open the quick-connect pipe to disconnect it from the tank cover 35. Manually push the screw conveyor 2 to rotate the discharge valve around the rotary joint, moving the screw conveyor 2 away from the tank cover 35. The electric lifting screw 32 then lifts the tank cover 35, completely separating it from the mixing tank 7. The electric push rod 29 pushes back, causing the side clamping rod 30 to swing outward, releasing the clamping fixation. At this point, the operator inserts the forklift forks into the two clearance areas of the tank placement seat 40 to remove the mixing tank 7 from the tank placement seat 40, facilitating material removal or replacement of the next mixing tank.

[0101] After being removed, the finished product is discharged through the discharge valve 43 at the liquid outlet end of the mixing tank body 41, thus completing the discharge process.

[0102] When the lifting and stirring cover mechanism 6 is raised, the liquid receiving tray 24 set on the liquid column 23 can be rotated to below the tank cover 35 to receive residual dripping liquid and prevent contamination of the working environment; when not in use, the liquid receiving tray 24 can be rotated and retracted to save space.

[0103] The entire device can be operated up and down with the aid of the ladder frame 4, enabling convenient feeding, proportioning, mixing and discharging processes.

[0104] In summary, by pre-mixing various liquid raw materials through the proportioning and initial mixing mechanism, combined with the quantitative feeding of the powder addition mechanism and the auxiliary material conveying of the liquid addition mechanism, the accurate proportioning and independent control of powder, liquid and auxiliary materials in stages are achieved, effectively ensuring the accuracy of the raw material proportioning of foliar fungicide.

[0105] The powder feeding mechanism uses a screw conveyor to achieve closed conveying of powder, effectively preventing material from flying; at the same time, the side of the feeding hood is connected to a dust collection filter box, which uses a dust collection pipe to timely suck up and filter the dust generated during feeding, preventing dust from escaping and polluting the environment, and ensuring a clean and safe workplace.

[0106] The tank clamping mechanism uses an electric push rod to drive the side clamping rod and the limiting frame to stably clamp the mixing tank from three directions. The manual locking rod enhances reliability and prevents the tank from shifting during mixing. The lifting and lowering mixing cover mechanism automatically seals the tank opening, ensuring a tight and leak-free mixing process.

[0107] In the lifting and stirring cover mechanism, the stirring motor drives the gear disk and transmission gear to mesh, driving two rotating stirring frames to fully mix the materials in the tank; at the same time, the scraper on the outside of the cylinder scrapes off the adhering substances on the tank wall as it rotates. The scraper and stirring frame are arranged in a cross shape, without interfering with each other, achieving efficient mixing without dead corners.

[0108] The mixing tank has a double-layer tank structure with good heat preservation performance. The heating rod inside can heat the materials during the mixing process, and the temperature sensor detects the heating temperature to meet the temperature requirements for the preparation of the microbial agent. The finished product is discharged through the discharge valve, and the entire mixing tank can be taken out as a whole from the clearance area of ​​the tank placement seat by a forklift, which is convenient for transportation and replacement.

[0109] The liquid receiving tray of the liquid addition mechanism can rotate to its lower position when the lifting and stirring cover mechanism is raised to collect residual dripping liquid, preventing pollution of the working environment. It can be retracted to save space when not in use. A ladder frame is set on the rear side of the main frame to facilitate operators to add materials from high places and maintain the equipment.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
