Description

Technical Field

[0001] This invention relates to the field of ferromolybdenum production equipment, and in particular to an intelligent raw material proportioning, mixing and processing integrated device for ferromolybdenum production. Background Technology

[0002] Ferromolybdenum, a ferroalloy composed of molybdenum and iron, plays a vital role in modern industry, especially in the steel industry, where it is an indispensable alloying additive. The addition of molybdenum to steel promotes the formation of a uniform, fine-grained structure, significantly improves hardenability, and effectively eliminates temper brittleness. In high-speed steel manufacturing, molybdenum can partially replace tungsten. In synergy with other alloying elements, it is widely used in the production of stainless steel, heat-resistant steel, acid-resistant steel, and tool steel, and can also impart special physical properties to the alloys. Adding molybdenum to cast iron can significantly enhance its strength and wear resistance. Currently, in ferromolybdenum production, the effective mixing of different raw materials is crucial to the quality of the ferromolybdenum. Current production methods primarily involve mixing the raw materials according to a specified ratio before adding the mixture for processing; however, this increased mixing time prolongs the smelting process.

[0003] Patent application number 202510330206.9 discloses a raw material mixing and processing equipment and method for iron production. It includes a vibrating base plate supported on the ground and a conveyor belt connected to the side wall of the support plate via a V-shaped frame. An L-shaped mounting plate is fixedly connected to one end of the bottom of the vibrating base plate, and multiple electronic scales are mounted on the L-shaped mounting plate. A pad flush with the vibrating base plate is provided at the top of each electronic scale. Multiple vibrating slide rails are evenly arranged on the surface of the conveyor belt, and connecting sliders are slidably arranged on the inner side of the vibrating slide rails. By using multiple conveying frames, mixing combs, alternating traction magnetic blocks, and alternating repulsion magnetic blocks, the raw materials are divided into multiple batches, and iron powder can be separated from other raw materials. During the raw material conveying process, non-iron powder raw materials are pre-mixed, and iron powder is dried, improving the mixing efficiency of the raw materials during feeding. However, the prior art has limitations in the mixing process of raw materials.

[0004] Due to the density differences in ferromolybdenum raw materials, such as high density iron briquettes and low density aluminum powder, simple rotary mixing may not be able to break up the density stratification, resulting in uneven mixing of heavy and light raw materials, which affects the smelting reaction efficiency of the furnace charge. In addition, the raw material premixing stage requires workers to place the raw materials on the corresponding pads, relying on manual feeding, which is not automated enough. In large-scale production, manual operation is prone to errors in raw material placement or weighing due to fatigue and misjudgment, affecting the overall proportioning accuracy. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides an intelligent raw material proportioning, mixing and processing integrated device for ferromolybdenum production, which effectively solves the problems mentioned in the background art.

[0006] The technical solution adopted by the present invention to solve the above problems is as follows:

[0007] An intelligent raw material proportioning and mixing integrated processing device for ferromolybdenum production includes a support frame. A sorting cylinder is rotatably connected to the upper side of the support frame. Multiple discharge cylinders are fixedly connected and connected to the outer side of the sorting cylinder. A mixing cylinder is fixedly connected to the bottom left side of the support frame. An agitating component is installed inside the mixing cylinder. An intermittent driving component is installed on the lower side of the sorting cylinder. A bevel gear transmission structure connects the intermittent driving component and the agitating component. When the intermittent driving component rotates, it can drive the agitating component to rotate. Under the drive of the intermittent driving component, the sorting cylinder can rotate intermittently. Each time the sorting cylinder rotates intermittently, one discharge cylinder corresponds to the upper and lower sides of the mixing cylinder.

[0008] A switch valve is installed at the bottom of the discharge cylinder. One end of the switch valve is equipped with a start end that controls the opening and closing of the switch valve. A stop end is installed on one side of the upper end of the mixing cylinder. When the discharge cylinder corresponds to the mixing cylinder, the start end moves under the obstruction of the stop end. When the start end moves, it controls the opening and closing of the switch valve. The distance between the start end and the stop end can be adjusted. The opening size of the switch valve is adjusted by controlling the distance between the start end and the stop end.

[0009] Furthermore, the switching valve includes two corresponding baffles slidably connected to the bottom of the discharge cylinder. The opening and closing of the bottom opening of the discharge cylinder is achieved by controlling the merging and opening of the two baffles. An arc-shaped frame is slidably connected radially to one side of the bottom of the discharge cylinder. A support spring is fixedly connected between the arc-shaped frame and the discharge cylinder. The two ends of the arc-shaped frame are respectively hinged to a first hinge rod. The other end of the first hinge rod is respectively hinged to the corresponding baffle. When the arc-shaped frame moves, the two baffles are driven to merge and open through the hinge rod.

[0010] Furthermore, the starting end includes an adjusting screw, which is threaded along the radial direction of the arc frame onto the surface of the arc frame, and the outer end of the adjusting screw is fixedly connected with a protrusion.

[0011] The blocking end includes a blocking plate fixedly connected to one side of the upper end of the mixing cylinder. The blocking plate has inwardly inclined slopes on both the front and rear sides of the end facing the discharge cylinder. When the discharge cylinder rotates with the sorting cylinder, the protrusion presses against the inclined surface. Under the guidance of the inclined surface, the arc frame moves towards the discharge cylinder. The distance between the protrusion and the arc frame can be adjusted by rotating the adjusting screw. By adjusting the distance between the protrusion and the arc frame, the movement distance of the arc frame after the protrusion is pressed by the inclined surface can be controlled.

[0012] Furthermore, a limiting rod is fixedly connected to the upper end of the arc-shaped frame in the radial direction, and a limiting cylinder is axially slidably connected to the surface of the limiting rod. The other end of the limiting cylinder is fixedly connected to the surface of the discharge cylinder.

[0013] Furthermore, the outer end of the protrusion has an arc-shaped structure, and the inclined surface of the guide plate is provided with grooves that can cooperate with the outer end of the protrusion.

[0014] Furthermore, the sorting cylinder includes an outer cylinder body and a partition plate fixedly connected to the inside of the cylinder body. The partition plate divides the space inside the cylinder body into multiple storage spaces. The number of storage spaces is equal to the number of discharge cylinders. The surface of the discharge cylinder is provided with an interface. The interface is fixedly connected to the surface of the sorting cylinder and communicates with the corresponding storage space. The lower side of each storage space is provided with an inclined plate that slopes towards the interface. The inclined plate is fixedly connected to the inner wall of the cylinder body.

[0015] Furthermore, the discharge cylinder has an axially rotatable rotating shaft inside, and a first helical blade is fixedly connected to the surface of the rotating shaft. The upper end of the rotating shaft extends out of the upper end of the discharge cylinder, and a connecting gear is fixedly connected to the upper end of the rotating shaft. An internal gear ring is provided on the outer side of the multiple connecting gears, and the internal gear ring is fixedly connected to the support frame.

[0016] Furthermore, the intermittent drive component includes a dial wheel and a grooved wheel that mesh with each other for transmission. A mounting frame is fixedly connected to the lower end of the sorting cylinder. The outer ends of the mounting frame are fixedly connected to the corresponding surfaces of the sorting cylinders. The grooved wheel is fixedly connected to the mounting frame on the same axis. A motor is provided on the lower side of the dial wheel. The motor is fixedly connected to the support frame. The power output end of the motor is fixedly connected to the dial wheel on the same axis.

[0017] Furthermore, the agitating component includes an agitating shaft coaxially disposed inside the mixing drum, a protective box rotatably connected to the surface of the agitating shaft, and the protective box being fixedly connected to the inner wall of the mixing drum; a spiral agitating blade is fixedly connected to the upper side of the agitating shaft, and an impeller is fixedly connected to the bottom of the agitating shaft;

[0018] When the agitator shaft rotates, the spiral agitator blades tend to push downwards in a spiral motion, while the impeller tends to push upwards.

[0019] The two output ends of the bevel gear transmission structure are connected to the agitator shaft and the groove wheel, respectively.

[0020] Furthermore, the bottom of the mixing cylinder has an open structure, and a bottom cover is provided at the bottom opening of the mixing cylinder. A bracket is fixedly connected to one side of the bottom of the bottom cover. A first pin and a second pin are fixedly connected to the upper and lower sides of one side surface of the bracket, respectively. A guide plate is provided on one side of the bracket. The guide plate is fixedly connected to the support frame. Guide grooves are respectively opened on the surface of the guide plate. The first pin and the second pin are slidably engaged in the inner side of the guide groove. A bearing block is slidably connected to the lower side of the guide groove. The bearing block is located below the second pin. Return springs are fixedly connected to both sides of the bottom of the bearing block, and the lower ends of the return springs are fixedly connected to the inner wall of the guide groove.

[0021] On the other side of the guide plate is a movable plate that can move horizontally. The movable plate is horizontally slidably connected to the bottom of the support frame. The movable plate is hinged to the bottom of the support frame with a second hinge rod. When the movable plate moves, the bottom cover can be driven to swing downward through the linkage of the second hinge rod.

[0022] The guide groove consists of a limiting vertical groove and a limiting arc groove. When the bottom cover swings downward, the first pin slides into the arc groove with the second pin as the center. A stop bar is fixedly connected to the surface of the moving plate. A drive shaft is fixedly connected to the lower end of the groove wheel on the same axis. A lever is fixedly connected to the bottom of the drive shaft. The lever is located to the left of the stop bar. During the rotation of the groove wheel, the lever pushes the stop bar to drive the moving plate to move away from the mixing drum.

[0023] This invention features a novel structure, ingenious design, and simple and convenient operation, offering the following advantages compared to existing technologies:

[0024] When in use, this device can load different raw materials required for ferromolybdenum production, such as molybdenum oxide, iron briquettes, ferrosilicon, sodium nitrate, aluminum powder, and calcium oxide, into multiple storage spaces in the sorting cylinder. These materials are then gradually placed into the mixing cylinder for mixing. During the gradual feeding process, the stirring components inside the mixing cylinder will rotate intermittently with the rotation of the sorting cylinder to stir the materials inside, thus fully improving the stirring effect.

[0025] When the grooved wheel rotates, it drives the agitator shaft to rotate through the bevel gear transmission structure. The spiral agitator blades push the raw material downwards, and the impeller pushes the raw material upwards, forming an upward and downward convection to achieve full mixing of the raw material.

[0026] During the rotation of the grooved wheel, the drive shaft drives the lever to rotate synchronously. The lever pushes the stop bar, causing the moving plate to move away from the mixing cylinder. The second hinge rod pulls the bracket, and the bottom cover swings downward to open, allowing the mixed raw materials to be discharged from the bottom of the mixing cylinder. After the lever disengages from the stop bar, the return spring pushes the bearing block to reset, and the bottom cover closes, achieving the effect of automatic material discharge.

[0027] When one of the discharge cylinders rotates to align with the mixing cylinder, the protrusion contacts the inclined surface of the guide plate. Guided by the inclined surface, the arc frame overcomes the elastic force of the support spring and moves towards the discharge cylinder. Through the hinge rod, it drives the two baffles to open, and the raw material in the storage space slides into the discharge cylinder through the inclined plate and falls into the mixing cylinder through the opened baffles. By rotating the adjusting screw to change the distance between the protrusion and the arc frame, the moving distance of the arc frame can be controlled, thereby adjusting the opening range of the baffles, realizing automatic intermittent feeding, and enabling precise control of the feeding amount.

Detailed Implementation

[0040] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0041] like Figures 1-11 As shown, this invention provides an intelligent raw material proportioning and mixing integrated processing device for ferromolybdenum production, including a support frame 1. The support frame 1 has a base plate at its lower end, a vertical plate fixedly connected to one side of the base plate, and a mounting ring fixedly connected to the upper end of the vertical plate. A sorting cylinder 2 is rotatably connected to the upper side of the support frame 1 for placing production raw materials, such as molybdenum oxide, iron ore, ferrosilicon, sodium nitrate, aluminum powder, and calcium oxide. The molybdenum element in the molybdenum oxide is reduced through a reduction reaction, and then combines with iron to form a ferromolybdenum alloy. At the same time, impurities are separated through slag formation. Multiple discharge cylinders 7 are fixedly connected and connected to the outer side of the sorting cylinder 2. A mixing cylinder 8 is fixedly connected to the bottom left side of the support frame 1. An agitator is installed inside the mixing cylinder 8 to agitate the material inside the mixing cylinder 8. The material inside the distribution cylinder enters the mixing cylinder 8 through the discharge cylinder 7 to provide the agitator for thorough agitation. An intermittent drive component is installed on the lower side of the sorting cylinder 2. A bevel gear transmission structure connects the intermittent drive component and the agitator. When the intermittent drive component rotates, it can drive the agitator to rotate. Under the drive of the intermittent drive component, the sorting cylinder 2 can rotate intermittently. Each time the sorting cylinder 2 rotates intermittently, a discharge cylinder 7 corresponds to the mixing cylinder 8 vertically.

[0042] A switch valve is installed at the bottom of the discharge cylinder 7, with a start end for controlling its opening and closing. A blocking end is installed on one side of the upper end of the mixing cylinder 8. When the discharge cylinder 7 aligns with the mixing cylinder 8, the starting end moves due to the blocking end, controlling the switch valve's opening and closing. After the switch valve opens, the material inside the discharge cylinder 7 enters the mixing cylinder 8 below, and the material inside the mixing cylinder 8 is stirred by the rotation of the agitator. This ensures that the agitator can stir the material already inside the mixing cylinder 8 whenever the sorting cylinder 2 rotates intermittently. Then, after the discharge cylinder 7 aligns with the mixing cylinder 8, the discharge cylinder 7 stops rotating, the agitator also stops rotating, and the switch valve opens, allowing the material to flow freely. The material enters the mixing drum 8. When the sorting drum 2 drives the discharge drum 7 to rotate again, the switch valve closes. During the rotation of the sorting drum 2, the stirring component rotates again to mix the material. This ensures that whenever a new material enters the mixing drum 8, the stirring component can be driven to stir the material inside, achieving the effect of gradually stirring the material as it is added. The distance between the starting end and the blocking end can be adjusted. By controlling the distance between the starting end and the blocking end, the opening size of the switch valve can be adjusted. By controlling the opening size of the switch valve, the amount of material discharged during the intermittent rotation and fixed stopping time of the sorting drum 2 can be controlled. The discharge amount can be precisely controlled according to the different proportions of the materials.

[0043] The switching valve includes two corresponding baffles 13 slidably connected to the bottom of the discharge cylinder 7. The opening and closing of the bottom of the discharge cylinder 7 is achieved by controlling the merging and opening of the two baffles 13. An arc-shaped frame 14 is slidably connected radially to one side of the bottom of the discharge cylinder 7. A support spring 18 is fixedly connected between the arc-shaped frame 14 and the discharge cylinder 7. The two ends of the arc-shaped frame 14 are respectively hinged to the first hinge rods 15. The other end of the first hinge rods 15 is respectively hinged to the corresponding baffles 13. When the arc-shaped frame 14 moves, the first hinge rods 15 drive the two baffles 13 to merge and open. The support spring 18 is used to push the arc-shaped frame 14 to reset. When the arc-shaped frame 14 is pressed and moves, the two baffles 13 open. When the arc-shaped frame 14 loses pressure, it is pushed to reset by the support spring 18, thereby causing the two baffles 13 to close again, thus closing the switching valve.

[0044] The starting end includes an adjusting screw 16, which is threadedly connected to the surface of the arc frame 14 along the radial direction of the arc frame 14. The outer end of the adjusting screw 16 is fixedly connected to a protrusion 17. Under the action of the threaded connection between the adjusting screw 16 and the arc frame 14, rotating the adjusting screw 16 can drive the protrusion 17 to move horizontally, thereby adjusting the distance between the protrusion 17 and the arc frame 14.

[0045] The blocking end includes a blocking plate 20 fixedly connected to one side of the upper end of the mixing cylinder 8. The blocking plate 20 has inwardly inclined slopes on both the front and rear sides of the end facing the discharge cylinder 7. When the discharge cylinder 7 rotates with the sorting cylinder 2, the protrusion 17 presses against the slope. Under the guidance of the slope, the arc frame 14 moves towards the discharge cylinder 7. The distance between the protrusion 17 and the arc frame 14 can be adjusted by rotating the adjusting screw 16. By adjusting the distance between the protrusion 17 and the arc frame 14, the movement distance of the arc frame 14 after the protrusion 17 is pressed by the slope can be controlled. Since the guide block is fixed, the farther the protrusion 17 is from the arc frame 14, the longer the overall length of the protrusion 17 and the arc frame 14. When the sorting cylinder 2 rotates, the distance the protrusion 17 moves under the obstruction of the blocking plate 20 is farther, and thus the range of the baffle 13 opening is larger, and vice versa.

[0046] A limiting rod 22 is fixedly connected radially to the upper end of the arc-shaped frame 14. A limiting cylinder 23 is axially slidably connected to the surface of the limiting rod 22. The other end of the limiting cylinder 23 is fixedly connected to the surface of the discharge cylinder 7. Limiting grooves are respectively opened on the corresponding two sides of the surface of the limiting rod 22. Limiting protrusions are respectively opened on the corresponding two sides of the inner wall of the limiting cylinder 23. Under the action of the sliding connection between the limiting protrusion and the limiting groove, the limiting rod 22 can only move axially inside the limiting cylinder 23 and cannot rotate. Under the action of the axial sliding connection between the limiting rod 22 and the limiting cylinder 23, the arc-shaped frame 14 can move horizontally stably.

[0047] The outer end of the protrusion 17 has an arc-shaped structure, and the inclined surface of the guide plate 41 is provided with grooves 21 that can cooperate with the outer end of the protrusion 17 to improve the stability of the contact between the protrusion 17 and the inclined surface and prevent slippage.

[0048] The sorting cylinder 2 includes an outer cylinder body and a partition plate 4 fixedly connected to the inside of the cylinder body. The partition plate 4 divides the space inside the cylinder body into multiple storage spaces for placing different materials. The number of storage spaces is equal to the number of discharge cylinders 7. The surface of the discharge cylinder 7 is provided with an interface 11, which is fixedly connected to the surface of the sorting cylinder 2 and connected to the corresponding storage space. The lower side of each storage space is provided with an inclined plate 5 that is inclined towards the interface 11. The inclined plate 5 is fixedly connected to the inner wall of the cylinder body to facilitate the flow of raw materials to the discharge cylinder 7.

[0049] The discharge cylinder 7 has a rotating shaft 9 rotatably connected to its interior along the axial direction. A first spiral blade 10 is fixedly connected to the surface of the rotating shaft 9. The upper end of the rotating shaft 9 extends out of the upper end of the discharge cylinder 7 and a connecting gear 12 is fixedly connected to the upper end of the rotating shaft 9. An internal gear ring 3 is provided on the outer side of the multiple connecting gears 12. The internal gear ring 3 is fixedly connected to the support frame 1. When the sorting cylinder 2 rotates, the connecting gear 12 rolls along the internal gear ring 3 and meshes, driving the rotating shaft 9 to rotate, so that the first spiral blade 10 rotates to push the raw material and prevents blockage.

[0050] The intermittent drive component includes a dial wheel 25 and a grooved wheel 26 that mesh and drive each other. The dial wheel 25 and the grooved wheel 26 form an intermittent grooved wheel mechanism. The lower end of the sorting cylinder 2 is fixedly connected to a mounting frame 24. The outer ends of the mounting frame 24 are fixedly connected to the corresponding surfaces of the sorting cylinder 2. The grooved wheel 26 is fixedly connected to the mounting frame 24 on the same axis. A motor 27 is provided on the lower side of the dial wheel 25. The motor 27 is fixedly connected to the support frame 1. The power output end of the motor 27 is fixedly connected to the dial wheel 25 on the same axis. When the motor 27 rotates, it drives the mounting frame 24 to rotate intermittently through the intermittent transmission between the grooved wheel 26 and the dial wheel 25, thereby driving the sorting cylinder 2 to rotate intermittently. The grooved wheel mechanism can rotate with different rotation amplitudes according to the number of discharge cylinders 7. In this embodiment, there are six discharge cylinders. The grooved wheel mechanism selected in this embodiment is a 60-degree grooved wheel mechanism, so that after each rotation of the sorting cylinder 2, one discharge cylinder 7 will be vertically aligned with the mixing cylinder 8, which is convenient for discharging materials.

[0051] The agitating component includes an agitating shaft 33 coaxially disposed inside the mixing drum 8. A protective box 36 is rotatably connected to the surface of the agitating shaft 33, and the protective box 36 is fixedly connected to the inner wall of the mixing drum 8. A spiral agitating blade 34 is fixedly connected to the upper side of the agitating shaft 33, and an impeller 35 is fixedly connected to the bottom of the agitating shaft 33. The impeller 35 is composed of multiple blades inclined in the same direction. The multiple inclined blades are fixedly connected to the agitating shaft 33 respectively. When the agitating shaft 33 rotates, the inclined blades can push the material upward.

[0052] When the agitator shaft 33 rotates, the spiral agitator blades 34 tend to push downwards in a spiral motion, while the impeller 35 tends to push upwards. The two output ends of the bevel gear transmission structure are connected to the agitator shaft 33 and the grooved wheel 26, respectively. When the grooved wheel 26 rotates, the bevel gear transmission structure enables the grooved wheel 26 to drive the agitator shaft 33 to rotate. When the agitator shaft 33 rotates, the spiral agitator blades 34 push the raw material downwards in a spiral motion, and the impeller 35 pushes the raw material upwards, forming convective mixing. This causes the heavier raw material to rise and the lighter material to sink, continuously circulating and mixing, effectively improving the mixing effect and preventing the heavier material from settling at the bottom and affecting the mixing effect. The bevel gear transmission structure includes an agitator shaft fixedly connected inside the protective box 36. The second connecting bevel gear 32 on the surface of the protective box 36 meshes with the first connecting bevel gear 31 on its lower side. The middle part of the first connecting bevel gear 31 is fixedly connected to the connecting shaft, which is rotatably connected to the surface of the protective box 36. The other end of the connecting shaft is fixedly connected to the second transmission bevel gear 30. The first transmission bevel gear 29 meshes with one side of the second transmission bevel gear 30. The first transmission bevel gear 29 is coaxially fixedly connected to the transmission shaft 28. When the grooved wheel 26 rotates, it rotates through the transmission shaft 28. When the transmission shaft 28 rotates, the linkage between the transmission shaft 28 and the agitator shaft 33 is realized through the transmission of the first connecting bevel gear 31, the second connecting bevel gear 32, the connecting shaft, the first transmission bevel gear 29, and the second transmission bevel gear 30.

[0053] The bottom of the mixing cylinder 8 is open, and a bottom cover 37 is provided at the bottom opening of the mixing cylinder 8. A bracket 38 is fixedly connected to one side of the bottom of the bottom cover 37. A first pin 39 and a second pin 40 are fixedly connected to the upper and lower sides of one side surface of the bracket 38, respectively. A guide plate 41 is provided on one side of the bracket 38. The guide plate 41 is fixedly connected to the support frame 1. A guide groove is opened on the surface of the guide plate 41. The first pin 39 and the second pin 40 are slidably engaged in the inner side of the guide groove. A bearing block 47 is slidably connected to the lower side of the guide groove. The bearing block 47 is located below the second pin 40. A return spring 48 is fixedly connected to both sides of the bottom of the bearing block 47. The lower end of the return spring 48 is fixedly connected to the inner wall of the guide groove. The bearing block 47 is used to support the second pin 40 and provides a support point for the second pin 40 through the support spring 18.

[0054] On the other side of the guide plate 41, there is a movable plate 44 that can move horizontally. The movable plate 44 is horizontally slidably connected to the bottom of the support frame 1. The movable plate 44 is hinged to the bottom of the bracket 38 by a second hinge rod 46. When the movable plate 44 moves, the bottom cover 37 can be driven to swing downward through the linkage of the second hinge rod 46.

[0055] The guide groove consists of a limiting vertical groove 42 and a limiting arc groove 43. When the bottom cover 37 swings downward, the first pin 39 slides inward about the second pin 40. A stop bar 45 is fixedly connected to the surface of the moving plate 44. A drive shaft 28 is fixedly connected to the lower end of the groove wheel 26 on the same axis. A lever 49 is fixedly connected to the bottom of the drive shaft 28. The lever 49 is located to the left of the stop bar 45. During the rotation of the groove wheel 26, the lever 49 pushes the stop bar 45, which can drive the moving plate 44 to move away from the mixing cylinder 8. The bracket 38 is pulled by the second hinge rod 46. When the moving plate 44 pulls the bracket 38 downward by the second hinge rod 46, the bracket 38 has a downward... The component force and the component force in the direction of moving the moving plate 44, and because the first pin 39 is limited by the limiting vertical groove 42, the bottom cover 37 can only move downward under the action of the downward moving component force in the initial stage. When the first pin 39 moves to the position of the limiting arc groove 43, after the first pin 39 corresponds to the limiting arc groove 43, the component force in the direction of moving the moving plate 44 plays a role in driving the bracket 38 to swing, so that the first pin 39 slides in the direction of the limiting arc groove 43, and drives the bottom cover 37 to swing downward, opening the lower end opening of the mixing cylinder 8, and unloading the mixed material. As the groove wheel 26 continues to rotate, after the lever 49 disengages from the stop lever 45, the return spring 48 pushes the bearing block 47 to reset, and the bottom cover 37 closes.

[0056] Based on the above principle, after each rotation of the grooved wheel 26, the material from each discharge cylinder 7 can be discharged into the mixing cylinder 8 in a specified proportion. During the process, the stirring component gradually stirs the material inside the mixing cylinder 8, so that the material inside the mixing cylinder 8 is fully mixed. After the grooved wheel 26 rotates once, the lever 49 pushes the stop bar 45 to move the moving plate 44, causing the bottom cover 37 to open. The mixed material is discharged through the bottom opening of the mixing cylinder 8. Then, as the grooved wheel 26 continues to rotate, the lever 49 disengages from the stop bar 45, the bottom cover 37 closes, and the material continues to be collected and mixed.

[0057] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains can make various modifications or additions to the described specific embodiments or use similar methods to replace them.
