Description

Technical Field

[0001] The present invention relates to the technical field of agriculture, and in particular to a composite herbicide targeting Xanthium sibiricum and a preparation method thereof. Background Art

[0002] Xanthium sibiricum is an annual herbaceous plant of the genus Xanthium in the Asteraceae family, with strong ecological adaptability and invasiveness. As an invasive plant, Xanthium sibiricum poses a serious threat to agriculture, ecology, and human health. In agriculture, it competes with crops for water, nutrients, sunlight, and space, resulting in reduced crop yields. The barbs on its fruits easily adhere to crop fruits, affecting the quality of agricultural products. Ecologically, Xanthium sibiricum forms a single dominant population in invaded areas, significantly reducing biodiversity. The allelopathic substances secreted by its roots can also inhibit seed germination and seedling growth of other plants, disrupting the ecological balance.

[0003] Generally speaking, when workers spray pesticides on Xanthium sibiricum, they usually use compound herbicides for spraying. The preparation process of compound herbicides requires multiple steps of mixing, extrusion and drying. The compound herbicide needs to be constantly moved during the preparation process, which affects the preparation efficiency of the compound herbicide.

[0004] In summary, how to solve the problem that the compound herbicide needs to be constantly transferred during the preparation process, thereby affecting the preparation efficiency of the compound herbicide, has become a technical challenge that those skilled in the art need to solve urgently. Therefore, it is necessary to propose a compound herbicide for Xanthium tuberosum and its preparation method. Summary of the Invention

[0005] To solve the above problems, the present invention provides a composite herbicide for Xanthium sibiricum and a preparation method thereof. The composite herbicide added to a storage tank is stirred by a stirring blade, and then the composite herbicide is squeezed by the movement of the stirring blade. The squeezed composite herbicide is then crushed by a crushing blade, and finally the crushed composite herbicide particles are dried by gas ejected from a piston cylinder. This simplifies the preparation process of the composite herbicide and improves the preparation efficiency of the composite herbicide.

[0006] In order to achieve the above purpose, the technical solution of the present invention is as follows: a composite herbicide for Xanthium sibiricum, 150ml of chlorpyrifos, 60ml of florasulam, 1.5g of alkyl polyglycosides, 7g of polyvinyl alcohol, 100g of diatomaceous earth and 70ml of distilled water.

[0007] Furthermore, a method for preparing a composite herbicide for Xanthium sibiricum comprises the following steps:

[0008] Step 1: Prepare a polyvinyl alcohol solution: Select 7 g of polyvinyl alcohol and 70 ml of distilled water, mix and stir to prepare a polyvinyl alcohol solution.

[0009] Step 2, preparing the composite herbicide: adding 150 ml of benafol, 60 ml of florasulam and 1.5 g of alkyl polyglycosides into the storage component of the preparation device, followed by preliminary stirring by the stirring component.

[0010] Step 3, adding polyvinyl alcohol solution: slowly add the polyvinyl alcohol solution into the storage component, and stir it twice by the stirring component.

[0011] Step 4, filling with diatomaceous earth: 100 g of diatomaceous earth was added into the storage component three times, and the stirring component was stirred for 5 minutes after each addition of diatomaceous earth to prepare the composite herbicide into a flowable paste.

[0012] Step 5, making granules: the flowable paste-like composite herbicide is extruded by the stirring component, and then the extruded composite herbicide is cut and crushed by the cutting component to make granular composite herbicide.

[0013] Step 6, drying the particles: using a drying component to dry the particle-shaped composite herbicide to obtain a finished composite herbicide.

[0014] Furthermore, in step 2, the initial stirring parameter is 200 r / min, and the stirring is carried out for 10 minutes.

[0015] Furthermore, in step three, the secondary stirring parameter is 300 r / min, and the stirring is performed for 20 min.

[0016] Furthermore, in step six, the drying process parameter is drying for 30 minutes.

[0017] Furthermore, the preparation device includes a housing having a feed inlet at the top, a discharge outlet at one side, and a vent in the middle. The storage assembly includes a storage box and a controller. The storage box is fixedly connected to the housing and communicates with the feed inlet. An extrusion port is defined at the bottom of the storage box. A first solenoid valve is fixedly connected to the extrusion port. The controller is configured to control the opening and closing of the first solenoid valve. A guide tube is fixedly connected to the extrusion port. The storage box also has an opening in a sidewall, a telescopic plate fixedly connected to the opening.

[0018] Furthermore, the stirring assembly includes a first fixed plate and a second fixed plate, and the first fixed plate and the second fixed plate are both fixedly connected between the inner wall of the box body and the storage box. The first fixed plate is fixedly connected to the bottom of the first fixed plate with a first driving member and a second driving member, and a controller is used to control the operation of the first driving member and the second driving member respectively. The output shaft of the first driving member is fixedly connected to a rotating rod, and the end of the rotating rod away from the first driving member passes through the first fixed plate and the second fixed plate, and the first fixed plate and the second fixed plate are both rotatably matched with the rotating rod. The output shaft of the second driving member near one end of the first fixed plate is fixedly connected to a threaded rod, and the end of the threaded rod away from the second driving member passes through the first fixed plate and the second fixed plate, and the first fixed plate and the second fixed plate are both rotatably matched with the threaded rod. A fixed rod is also fixedly connected between the first fixed plate and the second fixed plate.

[0019] Furthermore, the stirring assembly also includes a running box, which is located between the first fixed plate and the second fixed plate. The rotating rod passes through the running box and slides with the running box. The threaded rod passes through the running box and threads with the running box. The fixed rod passes through the running box and slides with the running box.

[0020] Furthermore, a first gear is rotatably engaged with the bottom wall of the operating box. The first gear is mounted on a rotating rod. A number of limit bars are fixedly connected to the inner sidewall of the first gear. The rotating rod has limit slots circumferentially defined thereon, each of which slides in engagement with the limit bars. The first gear meshes with a second gear, which rotatably engages with the inner sidewall of the operating box. The end of the second gear, away from the first gear, is fixedly connected to a stirring rod. The stirring rod extends through a telescopic plate into the storage box and is fixedly connected to a stirring blade. A tilt sensor is fixedly connected to the stirring blade, and a controller is configured to receive angle data monitored by the tilt sensor.

[0021] Furthermore, the cutting assembly includes a breaker rod, which is fixedly connected to the output shaft of the second drive member at one end away from the first fixed plate, and a breaker blade is fixedly connected to the breaker rod circumferentially. The drying assembly includes a piston cylinder and a blow box. The piston cylinder is fixedly connected to the top of the first fixed plate, and is provided with an air inlet and an air outlet. Both the air inlet and the air outlet are fixedly connected with a one-way valve. The air inlet is connected to the air vent, and the air outlet is fixedly connected to a gas pipeline. The end of the gas pipeline away from the air outlet is connected to the blow box. A piston head is slidably fitted in the piston cylinder, and a push rod is hinged to the end of the piston head away from the air inlet. The end of the push rod away from the piston head is hinged to the operation box. The blow box is fixedly connected to the bottom wall of the box body, and is provided with a blow port. A second solenoid valve is fixedly connected to the blow port, and the controller is used to control the operation of the second solenoid valve.

[0022] The technical principle behind this solution is as follows: fenpyroximate and florasulam form a dual-action weed control system. Benzothiazolin is a benzothiadiazinone herbicide that inhibits plant photosynthesis, while florasulam is an acetolactate synthase inhibitor that blocks branched-chain amino acid synthesis. The combination of these two agents produces a synergistic effect, broadening the weed control spectrum and delaying the development of pesticide resistance.

[0023] The first drive element drives the rotating rod, which in turn rotates the stirring blades. The second drive element drives the threaded rod, which moves the operating box axially along the fixed rod. This combined rotational and translational motion causes the stirring blades to simultaneously move radially while revolving, creating a three-dimensional stirring flow field that ensures uniform mixing of the raw materials.

[0024] The first driving member is closed and only the second driving member is opened. The reciprocating motion of the stirring blade in the storage box will squeeze the stirred composite herbicide out through the extrusion port, and then the composite herbicide is cut into particles by the crushing blade.

[0025] When the operating box moves downward, the push rod drives the piston head to slide in the piston cylinder, sucking air through the air inlet and vent, and transporting it to the blowing box through the air pipeline, and then drying the composite herbicide particles.

[0026] The above scheme has the following beneficial effects:

[0027] 1. The composite herbicide of this invention achieves synergistic effects through multiple mechanisms of action through a scientific formulation. Benzochlorfenapyr, a benzothiadiazinone herbicide, inhibits the electron transport chain in plant photosynthesis, leading to weed death due to energy starvation. Florasulfuron, an acetolactate synthase inhibitor, blocks the synthesis of branched-chain amino acids, hindering weed protein synthesis. The combination of these two significantly reduces the risk of drug resistance caused by long-term use of a single component.

[0028] 2. The present invention utilizes a first drive member to drive a rotating rod, which in turn rotates the stirring blade. A second drive member, via a threaded rod, drives the operating box to move axially along the fixed rod. The rotation and movement of the stirring blade enhances the mixing of the different drugs within the storage box, resulting in a more uniform mixing of the different drugs. When the composite herbicide needs to be extruded from the extrusion port, it can be directly extruded by the translation of the stirring blade, optimizing efficiency and ensuring continuous extrusion of the composite herbicide. Simultaneously, the rotation of the second drive member drives the crushing blade to cut the extruded composite herbicide, improving the efficiency of the composite herbicide crushing.

[0029] 3. The present invention dries the composite herbicide granules using a drying assembly. When the operating box moves downward, the push rod drives the piston head to perform work within the piston cylinder, drawing in ambient air through the air inlet and vent. The air is then transported via an air pipeline to the blow box for storage. When drying is required, air is blown from the blow box's air port, drying the composite herbicide.

[0030] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following is further described in detail through specific implementation methods:

[0038] Example 1:

[0039] A composite herbicide for Xanthium sibiricum comprises 150 ml of herbicide-resistant benzoylmethane, 60 ml of florasulam, 1.5 g of alkyl polyglycosides, 7 g of polyvinyl alcohol, 100 g of diatomaceous earth and 70 ml of distilled water.

[0040] The specific implementation process is as follows: fenpyroximate and florasulam are the core active ingredients. The former kills broadleaf weeds by inhibiting fatty acid synthesis, while the latter blocks branched-chain amino acid synthesis to expand the weed control spectrum. The combination significantly enhances efficacy and delays resistance. Alkyl polyglycosides act as surfactants to enhance the permeability of the solution, while polyvinyl alcohol and diatomaceous earth form a sustained-release carrier to prolong the efficacy. The porous structure of diatomaceous earth also improves the formability of the paste. Distilled water is used as a solvent to ensure the complete dissolution of the polyvinyl alcohol, forming a paste with an optimal moisture content. The final formula, through scientific proportions, achieves highly effective weed control, extended long-lasting effects, and environmentally friendly production.

[0041] Example 2:

[0042] like Figure 1 As shown, a method for preparing a composite herbicide for Xanthium sibiricum comprises the following steps:

[0043] Step 1: Prepare a polyvinyl alcohol solution: Mix 7g of polyvinyl alcohol and 70ml of distilled water and stir to prepare a polyvinyl alcohol solution. Continuously stir the polyvinyl alcohol solution until it becomes transparent and viscous, ensuring that the polyvinyl alcohol is completely dissolved, thereby providing a uniform mixing base for subsequent steps.

[0044] Step 2: Prepare the composite herbicide: Add 150ml of benomyl, 60ml of florasulam, and 1.5g of alkyl polyglycosides to the storage component of the preparation device. The stirring component then performs preliminary stirring. Initial stirring is performed at 200 rpm for 10 minutes. This initial stirring ensures that the three ingredients are thoroughly mixed. The purpose of this initial stirring is to form a uniform mixture of benomyl, florasulam, and alkyl polyglycosides, preparing for the subsequent addition of the polyvinyl alcohol solution.

[0045] Step 3: Add the polyvinyl alcohol solution: Slowly add the polyvinyl alcohol solution to the storage component and use the stirring component to perform a secondary stirring. The secondary stirring parameter is 300 rpm for 20 minutes. This secondary stirring ensures that the polyvinyl alcohol solution is fully integrated with the previous mixture. The purpose of the secondary stirring is to allow the polyvinyl alcohol to act as a binder, tightly binding the various components together to form a stable composite system.

[0046] Step 4: Fill with diatomaceous earth: Add 100g of diatomaceous earth to the reservoir assembly in three separate additions. Stir for 5 minutes after each addition. Add the diatomaceous earth in separate batches to avoid uneven mixing caused by adding too much at once. After stirring, the composite herbicide should form a flowable paste.

[0047] Step 5: Granulation: The blending assembly squeezes the flowable paste of the composite herbicide and forces it out of the extrusion port of the storage assembly. The cutting assembly then cuts and shatters the extruded composite herbicide into granules. The cutting process ensures that the resulting granules are uniform in size and shape.

[0048] Step 6: Drying the Granules: The granules are dried using a drying assembly to produce the finished compound herbicide. The drying process is performed for 30 minutes. During the drying process, the granules are regularly checked for dryness to ensure they meet the final product requirements. Upon completion, the finished compound herbicide is obtained. This drying process removes excess moisture from the compound herbicide granules, improving their stability and storage performance.

[0049] Example 3:

[0050] like Figure 2 As shown, the preparation device includes a box body 1, a feed port 2 is opened on the top of the box body 1, a discharge port 3 is opened on one side of the box body 1, and a vent hole is opened in the middle of the box body 1. Figure 5 As shown, the storage assembly includes a storage box 16 and a controller. The storage box 16 is bolted to the box body 1 and communicates with the feed port 2. The storage box 16 has an extrusion port at the bottom, and a first solenoid valve is screwed into the extrusion port. The controller is used to control the opening and closing of the first solenoid valve. The extrusion port is bolted to a guide tube 19. The storage box 16 has an opening on the side wall, and a telescopic plate 22 is bolted into the opening.

[0051] Combine Figure 3 As shown, the stirring assembly includes a first fixed plate 4 and a second fixed plate 6, and the first fixed plate 4 and the second fixed plate 6 are both bolted and fixedly connected between the inner wall of the box body 1 and the storage box 16. The first fixed plate 4 is bolted and fixedly connected to the bottom of the first fixed plate 4 with a first drive member and a second drive member. In this embodiment, the first drive member is selected as a drive motor 11, and the second drive member is selected as a double-headed motor 12. The controller is used to control the operation of the drive motor 11 and the double-headed motor 12 respectively. The output shaft of the drive motor 11 is bolted and fixedly connected to a rotating rod 7. The end of the rotating rod 7 away from the drive motor 11 passes through the first fixed plate 4 and the second fixed plate 6. The first fixed plate 4 and the second fixed plate 6 are both rotatably matched with the rotating rod 7. The output shaft of the double-headed motor 12 near one end of the first fixed plate 4 is bolted and fixedly connected to a threaded rod 8. The end of the threaded rod 8 away from the double-headed motor 12 passes through the first fixed plate 4 and the second fixed plate 6. The first fixed plate 4 and the second fixed plate 6 are both rotatably matched with the threaded rod 8. A fixing rod 9 is also bolted and fixedly connected between the first fixed plate 4 and the second fixed plate 6.

[0052] The stirring assembly also includes an operating box 5, which is located between the first fixed plate 4 and the second fixed plate 6. The rotating rod 7 passes through the operating box 5 and slides with the operating box 5. The threaded rod 8 passes through the operating box 5 and threads with the running box 5. The fixed rod 9 passes through the running box 5 and slides with the running box 5.

[0053] Combine Figure 4 As shown, a first gear 14 is rotatably engaged with the bottom wall of the operating box 5. The first gear 14 is sleeved on the rotating rod 7. The inner wall of the first gear 14 is bolted to a plurality of limit bars. The rotating rod 7 has limit slots circumferentially formed thereon, and the limit slots are slidably engaged with the limit bars. The first gear 14 is meshed with a second gear 15, which is rotatably engaged with the inner wall of the operating box 5. The end of the second gear 15 away from the first gear 14 is bolted to a stirring rod. The stirring rod extends through the telescopic plate 22 into the storage box 16 and is bolted to a stirring blade 10. The stirring blade 10 is screwed to an inclination sensor. The controller is used to receive angle data monitored by the inclination sensor.

[0054] The cutting assembly includes a breaker rod, which is fixedly connected to the output shaft of the double-headed motor 12 at one end away from the first fixed plate 4 with bolts, and a breaker blade 13 is fixedly connected to the breaker rod with bolts circumferentially.

[0055] Combine Figure 5 As shown, the drying assembly includes a piston cylinder 21 and a blow box 20. The piston cylinder 21 is fixedly connected to the top of the first fixed plate 4 by bolts. An air inlet and an air outlet are provided on the piston cylinder 21. A one-way valve is fixedly connected to the air inlet and the air outlet by screws. The air inlet is connected to the air vent, and the air outlet is fixedly connected to the gas pipeline by screws. The end of the gas pipeline away from the air outlet is connected to the blow box 20. A piston head 18 is slidably fitted in the piston cylinder 21. A push rod 17 is hinged to the end of the piston head 18 away from the air inlet. The end of the push rod 17 away from the piston head 18 is hinged to the operation box 5. The blow box 20 is fixedly connected to the inner bottom wall of the box body 1 by bolts. An air outlet is provided on the blow box 20. A second solenoid valve is fixedly connected to the air outlet by screws. The controller is used to control the operation of the second solenoid valve.

[0056] The specific implementation process is as follows: Figure 2 For example, a worker can add 150 ml of benafol, 60 ml of florasulam and 1.5 g of alkyl polyglycosides into the storage box 16 in sequence through the feed port 2 on the top of the box body 1 .

[0057] by Figure 3 and Figure 4For example, the operator can then control the operation of the drive motor 11 and the double-headed motor 12 through the controller. The operation of the drive motor 11 drives the rotating rod 7 to rotate. When the rotating rod 7 rotates, the rotating rod 7 drives the first gear 14 to rotate. The rotation of the first gear 14 further drives the second gear 15 to rotate. The rotation of the second gear 15 drives the stirring blade 10 to rotate through the stirring rod, thereby fully stirring the composite herbicide in the storage box 16.

[0058] When the double-headed motor 12 is running, the double-headed motor 12 drives the threaded rod 8 to rotate. Since the rotating rod 7 and the fixed rod 9 are both slidably engaged with the running box 5, and the running box 5 is threadedly engaged with the threaded rod 8, the rotation of the threaded rod 8 drives the running box 5 to move up and down in the box body 1. At this time, the up and down movement of the running box 5 also drives the stirring rod and the stirring blade 10 to move up and down. As the stirring rod moves up and down, the stirring rod drives the telescopic plate 22 to extend and retract up and down.

[0059] The mixing effect is enhanced by the rotation and up-and-down movement of the stirring blade 10. The stirring is continued for 10 minutes to fully mix the benazolin, florasulam and alkyl polyglycosides.

[0060] After the initial stirring is complete, the staff can add the pre-prepared polyvinyl alcohol solution to storage tank 16 and continue stirring. After the secondary stirring is complete, diatomaceous earth is divided into three equal portions and added sequentially through feed port 2 of storage tank 16. The diatomaceous earth and composite herbicide are thoroughly mixed. As the diatomaceous earth is gradually added, the viscosity of the composite herbicide gradually increases, eventually forming a flowable paste.

[0061] Combine Figure 5 As shown, when the composite herbicide is stirred into a paste, the operator can use the controller and the tilt sensor to determine the angle of the stirring blade 10. When the controller determines that the stirring blade 10 is in a horizontal state through the tilt sensor, the controller can control the drive motor 11 to turn off, while the double-headed motor 12 continues to operate. At the same time, the operator can control the first solenoid valve to open through the controller.

[0062] At this time, the stirring blade 10 is in a horizontal state in the storage box 16. When the drive motor 11 is turned off, the rotating rod 7 will stop rotating. At this time, the first gear 14 and the second gear 15 will also stop rotating. Therefore, the stirring blade 10 will stop stirring the composite herbicide in the storage box 16. As the double-headed motor 12 runs, the stirring blade 10 will still slide up and down in the storage box 16. At this time, as the stirring blade 10 slides up and down, the stirring blade 10 will squeeze the composite herbicide stirred into a paste. The paste composite herbicide will fall into the guide tube 19 through the extrusion port under the action of the squeezing of the stirring blade 10 and its own gravity, and then be introduced into the crushing blade 13 through the guide tube 19.

[0063] As the double-headed motor 12 is started, the double-headed motor 12 will continuously drive the crushing blade 13 to rotate through the crushing rod, cutting and crushing the paste-like composite herbicide into granular composite herbicide.

[0064] As the operating box 5 slides up and down, the piston head 18 will continue to slide up and down in the piston cylinder 21. Since the operating range of the operating box 5 is limited and is restricted by the telescopic plate 22, when the piston head 18 slides upward, the piston head 18 will not separate from the piston cylinder 21. At this time, the outside air enters the piston cylinder 21 through the vent hole. When the piston head 18 slides downward, the gas in the piston cylinder 21 enters the blow box 20 through the air outlet and the gas pipeline for storage.

[0065] When the granular composite herbicide needs to be dried, the staff can control the second solenoid valve to open through the controller, so that the gas in the blowing box 20 can be blown through the blowing port, thereby drying the granular composite herbicide for subsequent storage.

[0066] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
