Description

Technical Field

[0001] The present invention relates to the technical field of herbicide production, and more specifically, to a sulfentrazone and flumetsulam herbicide composition and production equipment. Background Art

[0002] Herbicides refer to agents that can completely or selectively cause weeds to wither and die, also known as weed killers, which are substances used to eliminate or inhibit plant growth and are widely used in farmland, orchards, flower nurseries, grasslands, non-cultivated lands, etc. to control harmful plants such as weeds, shrubs, and miscellaneous trees. Their use effect is significant, and they can quickly control the growth of weeds, saving time and labor costs.

[0003] During production, the mixing uniformity of raw materials directly affects the performance and quality of the herbicide composition. If the mixing is uneven, it will cause the concentration or mass fraction of each component in the composition to be unevenly distributed in space, thereby affecting the overall performance. For example, in the patent with the publication number CN220294548U, a mixing device for producing a herbicide composition is involved, including a base, a reaction barrel, and a barrel cover. A connecting plate is fixedly connected to the left side of the top of the base, the barrel cover is arranged on the right side of the reaction barrel, a fixing mechanism is fixedly connected inside the connecting plate, and a mixing mechanism is fixedly connected inside the reaction barrel; the fixing mechanism includes a rotating component and a limiting component, the limiting component is arranged on the rotating component, the rotating component includes a first motor, the first motor is fixedly connected to the left side of the connecting plate, a rotating shaft is fixedly connected to the right side of the first motor, a connecting circular plate is fixedly connected to the right side of the rotating shaft, a first annular sliding groove is opened on the right side of the connecting plate, and a first annular sliding block is fixedly connected to the left side of the connecting circular plate. The problem is that due to the different densities of different raw materials, under the action of gravity, light powders tend to float upward and heavy powders tend to sink downward. The mixed raw materials processed by the above mixing device have non-uniform texture, and there is still a problem of uneven mixing. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that due to the different densities of different raw materials, heavy raw materials sink and light raw materials float, resulting in uneven mixing of raw materials.

[0005] The purpose of the present invention is to provide a sulfentrazone and flumetsulam herbicide composition and production equipment. By dispersing and grinding the raw materials, then screening to produce raw material powders with consistent particle sizes, and then lifting the heavy raw material powders upward to fully mix with the light raw material powders to produce a herbicide composition with high mixing uniformity.

[0006] To achieve the above purpose, the present invention aims to provide a production equipment for a sulfentrazone and flumetsulam herbicide composition, including a mixing tank, a pulverizing body, and a mixing body; The mixing tank includes a tank body for accommodating pyroxasulfone and flumetsulam, and a driving structure arranged inside the tank body. A crushing chamber, a mixing chamber, and a movable chamber that are connected and communicated are arranged in the tank body from top to bottom; The crushing body includes a rotating shaft and a sieve plate arranged in the crushing chamber. The driving structure is in transmission connection with the rotating shaft. The rotating shaft is used to crush pyroxasulfone and flumetsulam into granular raw materials, and the granular raw materials fall into the mixing chamber after being filtered by the sieve plate; The mixing body includes a compound mixing structure located in the mixing chamber. The driving structure is in transmission connection with the compound mixing structure. The compound mixing structure is used to mix the granular raw materials.

[0007] Pyroxasulfone and flumetsulam are put into the crushing chamber. The driving structure drives the rotating shaft to rotate in the crushing chamber to crush and cut pyroxasulfone and flumetsulam to form raw material particles. The raw material particles pass through the sieve plate and fall into the mixing chamber. When the rotating shaft rotates, it can drive the sieve plate to move up and down along the inner wall of the crushing chamber, so that some raw material particles with too large particle sizes are driven to fly upward. The rotating shaft continues to crush the raw material particles with large particle sizes until the particle sizes of the raw material particles become smaller and can pass through the sieve plate and enter the mixing chamber. Moreover, the driving structure simultaneously drives the compound mixing structure to rotate to mix the raw material particles in the mixing chamber. After mixing, the raw material particles are discharged through the movable chamber.

[0008] As a further improvement of this technical solution, a feeding port for feeding is arranged at the top of the crushing chamber. The driving structure includes a motor arranged at the bottom of the tank body. The driving shaft of the motor is clamped and matched with a transmission shaft. The top end of the transmission shaft passes through the middle of the rotating shaft and is clamped and matched with the rotating shaft. A plurality of blades for crushing pyroxasulfone and flumetsulam are symmetrically arranged on the surface of the rotating shaft. The motor drives the transmission shaft to rotate through the driving shaft, and the transmission shaft then drives the rotating shaft to rotate in the crushing chamber, so that the blades arranged on the surface of the rotating shaft crush and cut pyroxasulfone and flumetsulam.

[0009] Further, the sieve plate is slidably connected to the inner wall of the crushing chamber up and down. A first reciprocating structure is arranged at the bottom of the rotating shaft. The rotating shaft drives the sieve plate to move up and down reciprocally through the arranged first reciprocating structure. The first reciprocating structure includes an extension handle arranged at the bottom edge of the rotating shaft and a first sleeve arranged in the middle of the sieve plate. The top end of the transmission shaft passes through the first sleeve. A second sliding groove is arranged on the side surface of the first sleeve. The second sliding groove is a groove formed by splicing a plurality of "V"-shaped grooves. The bottom end of the extension handle is slidably connected to the second sliding groove, so that the large-particle-size particles accumulated on the sieve plate are driven to fly upward by the sieve plate.

[0010] As a further improvement of the technical solution, the composite structure includes a stirring shaft and a discharge tray arranged below the stirring shaft. The stirring shaft is symmetrically arranged on the side wall of the transmission shaft. The connecting wall surface between the mixing chamber and the movable chamber bulges inward, and the side wall of the discharge tray fits against the protruding wall surface of the movable chamber. The stirring shaft includes inclined rods and a plurality of vertical rods arranged at equal intervals at the bottom of the inclined rods. The top of the inclined rod is connected to the side wall of the transmission shaft, and the vertical rods agitate the sulfentrazone granules and flumetsulam granules accumulated on the discharge tray.

[0011] As a further improvement of the technical solution, the mixture further includes a plurality of scraping plates. The scraping plates are strip-shaped plates with an arc-shaped cross-section and a smooth surface. One end of the scraping plate is connected to the outer wall of the transmission shaft, and the bottom surface of the scraping plate fits against the upper surface of the discharge tray. The scraping plates shovel up the heavy particles accumulated on the surface of the discharge tray, so that the heavy particles can be thrown upward along the smooth surface of the scraping plates and mixed into the light particles.

[0012] As a further improvement of the technical solution, a discharge port communicating with the movable chamber is provided on the side wall of the tank body. A plurality of limiting rods are further arranged in the movable chamber. The bottom of the discharge tray is inserted and matched with the limiting rods, and a second reciprocating structure is arranged at the bottom of the discharge tray. The discharge tray is connected to the drive shaft of the motor through the arranged second reciprocating structure.

[0013] Further, the second reciprocating structure includes a clamping shaft arranged on the drive shaft and a second sleeve arranged in the middle of the bottom of the discharge tray. The top of the drive shaft passes through the second sleeve. A first sliding groove is provided on the side surface of the clamping shaft. The first sliding groove is a groove with a "V"-shaped groove at one end. The bottom end of the second sleeve is slidably connected to the first sliding groove. When the drive shaft of the motor rotates one circle, the drive shaft drives the discharge tray to move downward once through the clamping shaft and the second sleeve.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In the sulfentrazone and flumetsulam herbicide composition and the production equipment, the drive structure drives the rotating shaft to rotate in the pulverizing chamber to pulverize and cut sulfentrazone and flumetsulam to form raw material particles. When the rotating shaft rotates, it can drive the sieve tray to make up and down reciprocating movements along the inner wall of the pulverizing chamber, so that some raw material particles with too large particle sizes are driven to fly upward. The rotating shaft contacts and pulverizes the raw material particles with large particle sizes until the particle sizes of the raw material particles become smaller and can pass through the sieve tray and enter the mixing chamber. It should be noted that when the transmission shaft rotates, the transmission shaft can drive the scraper to rotate synchronously, and then the heavy particles accumulated on the surface of the discharging plate can be shoveled up by the scraper, so that the heavy particles can be thrown upwards along the smooth surface of the scraper and mixed into the light particles, so that the heavy particles can be fully mixed with the light particles under the agitation of the stirring shaft, generating a herbicide composition with high mixing uniformity.

[0022] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0023] Embodiment 1 Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 As shown in the figure, the purpose of this embodiment is to provide a production device for a pyroxasulfone and flumetsulam herbicide composition, including a mixing tank 1, a crushing body 2, and a mixing body 3; The mixing tank 1 includes a tank body 11 for accommodating pyroxasulfone and flumetsulam and a driving structure arranged in the tank body 11. A crushing chamber 12, a mixing chamber 13, and a movable chamber 14 are opened in the tank body 11 from top to bottom and are connected in communication; The crushing body 2 includes a rotating shaft 21 and a sieve plate 22 arranged in the crushing chamber 12. The driving structure is in transmission connection with the rotating shaft 21. The rotating shaft 21 is used to crush pyroxasulfone and flumetsulam into granular raw materials, and the granular raw materials fall into the mixing chamber 13 after being filtered by the sieve plate 22; The mixing body 3 includes a compound mixing structure located in the mixing chamber 13. The driving structure is in transmission connection with the compound mixing structure, and the compound mixing structure is used to mix the granular raw materials.

[0024] Oxaziclomefone and flumetsulam are put into the crushing bin 12, and the driving structure drives the rotating shaft 21 to rotate in the crushing bin 12 to crush and cut oxaziclomefone and flumetsulam to form raw material particles. The raw material particles pass through the sieve plate 22 and fall into the mixing bin 13. When the rotating shaft 21 rotates, it can drive the sieve plate 22 to move up and down along the inner wall of the crushing bin 12, so that some raw material particles with too large particle size are driven to fly upward and contact the rotating shaft 21 for continuous crushing until the particle size of the raw material particles becomes smaller and can pass through the sieve plate 22 and enter the mixing bin 13. At the same time, the driving structure drives the compound mixing structure to rotate to mix the raw material particles in the mixing bin 13. After mixing, the raw material particles are discharged through the movable bin 14.

[0025] The above structure is disclosed as follows: Both oxaziclomefone and flumetsulam are solid substances. To ensure the uniform mixing of the above two substances, they need to be crushed, as Figure 3 、 Figure 4 shown. A feeding port 121 for feeding is opened at the top of the crushing bin 12. The driving structure includes a motor 15 arranged at the bottom of the tank body 11. The driving shaft of the motor 15 is clamped and matched with a transmission shaft 16. The top end of the transmission shaft 16 passes through the middle of the rotating shaft 21 and is clamped and matched with the rotating shaft 21. A plurality of blades 211 for crushing oxaziclomefone and flumetsulam are symmetrically arranged on the surface of the rotating shaft 21. After oxaziclomefone and flumetsulam are put into the crushing bin 12 through the feeding port 121, the motor 15 drives the transmission shaft 16 to rotate through the driving shaft, and the transmission shaft 16 then drives the rotating shaft 21 to rotate in the crushing bin 12, so that the blades 211 arranged on the surface of the rotating shaft 21 crush and cut oxaziclomefone and flumetsulam to reduce the particle size of oxaziclomefone and flumetsulam. When the particle size of oxaziclomefone and flumetsulam is qualified, that is, the particle size is smaller than the pore diameter of the sieve plate 22, the oxaziclomefone particles and flumetsulam particles pass through the sieve plate 22 and fall downward into the mixing bin 13.

[0026] During the crushing process, in order to prevent the oxaziclomefone and flumetsulam with large particle size from accumulating on the sieve plate 22 and blocking the pores of the sieve plate 22, and in order to continue to crush the oxaziclomefone and flumetsulam with large particle size to produce qualified particle size oxaziclomefone particles and flumetsulam particles, as Figure 4 、 Figure 5As shown, a groove is provided at the outer edge of the sieve plate 22, and a protrusion is correspondingly provided on the inner wall of the crushing bin 12 to be stuck in the groove. The sieve plate 22 and the inner wall of the crushing bin 12 are connected to each other by sliding up and down through the groove and the protrusion. A first reciprocating structure is provided at the bottom of the rotating shaft 21. The rotating shaft 21 drives the sieve plate 22 to reciprocate up and down through the first reciprocating structure. Specifically, the first reciprocating structure includes an extension handle 212 provided at the bottom edge of the rotating shaft 21 and a first sleeve 221 provided in the middle of the sieve plate 22. The top end of the transmission shaft 16 passes through the first sleeve 221. The side of the first sleeve 221 is provided with a The second slide groove 222 is a groove formed by splicing a plurality of "V"-shaped grooves. One end of the bottom of the extension handle 212 is located in the second slide groove 222 and is slidably connected to the second slide groove 222. When the transmission shaft 16 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the extension handle 212 to slide in the second slide groove 222. Since the sieve plate 22 is slidably connected to the inner wall of the crushing bin 12 up and down, when the extension handle 212 slides in the second slide groove 222, under the action of the groove structure of the second slide groove 222, the extension handle 212 can drive the sieve plate 22 to move up and down. Figure 8 As shown by the middle arrow a, the large-sized particles accumulated on the sieve plate 22 are driven by the sieve plate 22 to fly upward and leave the surface of the sieve plate 22, which can prevent the sieve plate 22 from being blocked by the large-sized particles. After being thrown upward, the large-sized particles come into contact with the blade 211 and are then crushed by the blade 211 until the particle size is qualified, thereby ensuring that the particle size of the sulfamethoxazole particles and the foramsulfuron particles meet the requirements when the raw materials are mixed.

[0027] After the sulfamethoxazole particles and the flumetsulam particles fall into the mixing bin 13, in order to ensure the uniformity of the raw material mixing, the sulfamethoxazole particles and the flumetsulam particles need to be further mixed, such as Figure 6 As shown, the compound mixing structure includes a stirring shaft 31 and a discharge tray 33 arranged below the stirring shaft 31, the stirring shaft 31 is symmetrically arranged on the side wall of the transmission shaft 16, the wall surface at the connection between the mixing bin 13 and the movable bin 14 is convex inward, the side wall of the discharge tray 33 is in contact with the convex wall surface of the movable bin 14, the stirring shaft 31 includes an inclined rod and a plurality of vertical rods equidistantly arranged at the bottom of the inclined rod, and the top of the inclined rod is connected to the side wall of the transmission shaft 16. When the sulfamethoxazole particles and the fluazifop-butyl particles fall into the mixing bin 13 and fall onto the discharge tray 33, the rotation of the transmission shaft 16 will drive the stirring shaft 31 to rotate with the transmission shaft 16 as the axis, and when the stirring shaft 31 rotates, the equidistantly arranged vertical rods will stir the sulfamethoxazole particles and the fluazifop-butyl particles accumulated on the discharge tray 33 for mixing.

[0028] Considering that the density of pyroxasulfone is 1.59±0.1 g / cm³ and the density of flumetsulam is 1.66 g / cm³, and the densities of the two are different. During stirring, under the action of gravity, the light particles tend to float upward and the heavy particles tend to sink, which easily leads to uneven texture of the raw materials after mixing and unsatisfactory mixing effect of the raw materials. To ensure the mixing effect of the raw materials, the mixing body 3 further includes a plurality of scraping plates 32. The scraping plates 32 are strip-shaped plates with an arc-shaped cross-section and a smooth surface. One end of the scraping plate 32 is connected to the outer wall of the transmission shaft 16, and the bottom surface of the scraping plate 32 fits with the upper surface of the discharge tray 33. By providing the scraping plates 32, when the transmission shaft 16 rotates, the transmission shaft 16 can drive the scraping plates 32 to rotate synchronously. With its arc-shaped structure, the scraping plates 32 can shovel up the heavy particles accumulated on the surface of the discharge tray 33, so that the heavy particles can be thrown upward along the smooth surface of the scraping plates 32 and mixed into the light particles, so that they can be fully mixed with the light particles under the stirring action of the stirring shaft 31. After the raw materials are fully mixed, to facilitate the discharge of the mixed raw materials, as Figure 6 、 Figure 7 shown, a discharge port 141 communicating with the movable bin 14 is opened on the side wall of the tank body 11. A plurality of limiting rods 142 are further provided in the movable bin 14. The bottom of the discharge tray 33 is inserted and matched with the limiting rods 142. A second reciprocating structure is provided at the bottom of the discharge tray 33. The discharge tray 33 is connected to the drive shaft of the motor 15 through the provided second reciprocating structure. Specifically, the second reciprocating structure includes a clamping shaft 151 provided on the drive shaft and a second sleeve 331 provided in the middle of the bottom of the discharge tray 33. The top end of the drive shaft passes through the second sleeve 331. A first sliding groove 152 is opened on the side surface of the clamping shaft 151. The first sliding groove 152 is a groove with a "V"-shaped groove provided at one end. The bottom end of the second sleeve 331 is slidably connected to the first sliding groove 152. When the second sleeve 331 slides to the "V"-shaped groove area of the first sliding groove 152, the second sleeve 331 moves downward along the "V"-shaped groove to drive the discharge tray 33 to move downward and separate from the convex wall surface of the movable bin 14, as Figure 8 shown by the arrow b in, so that the raw materials in the mixing bin 13 can enter the movable bin 14 through the gap between the discharge tray 33 and the wall surface of the movable bin 14, and then be discharged through the discharge port 141. That is, when the drive shaft of the motor 15 rotates one circle, the drive shaft drives the discharge tray 33 to move downward once through the clamping shaft 151 and the second sleeve 331, realizing periodic discharging.

[0029] Example 2 The mixed raw materials in the above example are dissolved in a solvent to obtain a herbicide composition and applied in medicaments such as suspension concentrates, wettable powders, and water-dispersible granules for preventing and controlling field weeds in soybeans, corn, and wheat. Among them, the content ratio of pyroxasulfone to flumetsulam is 1-40:1-40.

[0030] Oxaziclomefone belongs to the inhibitor of very-long-chain fatty acid elongase. By inhibiting the elongation of fatty acids in plants, it disrupts the formation of cell membranes and cuticular wax layers, and hinders the development of meristems in weed seedlings and roots. Flumetsulam belongs to the inhibitor of acetolactate synthase, which blocks the synthesis of branched-chain amino acids (valine, leucine, isoleucine), inhibits cell division, and is particularly effective against broad-leaved weeds and some sedges. Oxaziclomefone and flumetsulam target two independent biochemical pathways of lipid metabolism and amino acid synthesis respectively, double-blocking weed growth and significantly improving the herbicidal speed and thoroughness.

[0031] The following is to verify that when the content ratio of oxaziclomefone to flumetsulam is 1 - 40:1 - 40, the prepared herbicide composition has good weed control effect. Only by changing the content ratio of oxaziclomefone to flumetsulam, after preparing the herbicide composition, a soil sealing test of the herbicide composition is carried out indoors. The experimental process is as follows: Quantitative Abutilon theophrasti and Alopecurus japonicus were sown respectively in disposable paper cups with a height of 9 cm. After sowing, the soil was covered with 0.5 cm of soil, compacted and watered, and then placed in the greenhouse. The next day, spray treatment was carried out. Soil spraying treatment was carried out with a crawler crop sprayer according to the doses designed in the experiment (spray pressure 1.95 kg / cm2, liquid spraying amount 500 L / ha, crawler speed 1.48 km / h). The experiment was repeated 3 times. After the test materials were treated, they were placed in the operation hall. After the liquid medicine was naturally air-dried, they were placed in the greenhouse and managed according to the conventional method. Observe and record the reaction of weeds to the medicine, and visually investigate the control effect of the medicine and the safety to crops regularly (30 days). The change in the content ratio of oxaziclomefone to flumetsulam and the corresponding control effect are shown in Table 1.

[0032] Table 1: Changes in the content ratio of oxaziclomefone to flumetsulam and the corresponding control effect It can be seen from Table 1 that when the content ratio of oxaziclomefone to flumetsulam is 1 - 40:1 - 40, the control efficiency against Alopecurus japonicus is not less than 84%, and the control efficiency against Abutilon theophrasti is not less than 90%. This shows that when the content ratio of oxaziclomefone to flumetsulam is 1 - 40:1 - 40, the prepared herbicide composition has good weed control effect; In addition, when the content ratio of oxaziclomefone to flumetsulam is 1:50, 1:70, 50:1 or 70:1, that is, not 1 - 40:1 - 40, the control efficiency of the prepared herbicide composition against Alopecurus japonicus and Abutilon theophrasti is lower than that of the herbicide composition prepared when the content ratio of oxaziclomefone to flumetsulam is 1 - 40:1 - 40. This again shows that when the content ratio of oxaziclomefone to flumetsulam is 1 - 40:1 - 40, the prepared herbicide composition has good weed control effect.
