[0002] The sintering production process is as follows: the mixture is spread on the sintering trolley according to a certain thickness, and then the solid fuel in the mixture is ignited by the ignition furnace, and air is drawn under the grate bars at the bottom of the sintering trolley to form a negative pressure. Under the action of negative pressure, the mixture burns from bottom to top, and then at a high temperature of about 1200℃, the mixture is sintered to form sintered ore.

[0007] The material-dispensing device includes two rotating shafts, one of which is fixedly connected to the output shaft of the motor, and the two rotating shafts are respectively located below the conical plates. The two rotating shafts are connected by a transmission structure, and the outsides of the two rotating shafts are provided with multiple spiral grooves, and the insides of the multiple spiral grooves are slidably connected with sliding rods. One ends of the multiple sliding rods are respectively fixedly connected to multiple annular sleeves mounted on the rotating shafts, and the right ends of the multiple annular sleeves are fixedly connected to the same movable plate. The bottom of the movable plate is equipped with multiple material-dispensing plates distributed at the same distance.

[0008] As a further solution of the present invention: a pressing roller is installed at the bottom of the conical plate located on the right side of the scraper plate, and the placement height of the left conical plate is lower than that of the right conical plate.

[0009] As a further solution of the present invention: a controller is installed above the right side of the mixing trough and between the two alarms, and the discharging device includes an electric hydraulic rod, which is embedded and fixed in two fixing seats, and the two fixing seats are fixedly connected to the right side of the mixing trough.

[0014] A material distribution mechanism and a method for using the same for facilitating grading and layering, comprising the following steps:

[0015] S1. First, the electric hydraulic rod is used to drive the convex rod to move, so that the convex rod controls the roller body through the arc groove to drive the discharge plate to rotate. At this time, the discharge port of the mixing trough is opened for discharge, so that the material falls through the distribution roller for downward distribution. At the same time, the dividing roller grades and screens the material. The larger material falls to the lower left along the dividing roller, while the smaller material falls directly from the roller of the dividing roller to the conical plate, and is dispersed along the conical plate to the distribution trolley moving to the right, and the larger material is pre-arranged from the left side of the distribution trolley.

[0016] S2. When large and small materials are placed on the material distribution trolley respectively, the control motor drives the rotating shaft to rotate. Under the action of the transmission structure, the two rotating shafts rotate synchronously, so that the rotating shaft squeezes the control slide bar through the spiral groove to reciprocate back and forth along the spiral groove, so that the slide bar drives the annular sleeve and the movable plate to reciprocate back and forth, so that the movable plate drives the material stripping plate to reciprocate back and forth, so that the material stripping plate flattens the large and small materials.

[0017] S3. When the material is transported to the right by the distribution trolley, the scraper plate can accumulate excess material. When the material accumulates too much, the spring is deformed, causing the scraper plate to drive the docking plate to move to the right and press the switch. At this time, the switch can control the alarm to sound an alarm. At the same time, the controller controls the electric hydraulic rod to drive the convex rod to move, so that the convex rod drives the discharge plate to rotate through the arc groove to reduce the angle with the discharge port and reduce the discharge. When the scraper plate accumulates less material, the spring elastic force controls the docking plate to press the left switch through the scraper plate. At this time, the alarm is sounded again and the discharge of the discharge port is increased. At the same time, when the material is transported to the right, the pressing roller flattens the material so that the larger material is located on the lower layer and the smaller material is located on the upper layer of the large material to achieve uniform distribution operation.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention operates the reciprocating movement of the stripping plates on both sides of the stripping device, so that the stripping plates on both sides can realize the flattening operation of larger materials, and at the same time can also realize the flattening of materials of different sizes after distribution, so that the materials can be evenly distributed on the distribution trolley, avoiding the problem of uneven distribution caused by excessive or insufficient distribution in some parts, and the device can also detect the accumulation degree of the materials during the flattening process. If the accumulation degree of the materials is too much or too little, the elastic force of the elastic structure can be triggered to realize the alarm reminder operation, which is convenient for relevant personnel to find and adjust in time, and the size of the discharge port can be controlled by the discharging device to achieve the purpose of automatic adjustment when the thickness is uneven, meeting the demand for uniform distribution thickness, so that the device can ensure the uniformity of the material layer thickness, ensure the subsequent uniform sintering, and thus improve the subsequent sintering quality;

[0020] 2. The present invention sets a dividing roller, and the dividing roller is assembled by multiple rollers. The multiple rollers are rotatably connected to two mounting plates, so that when the material falls on the dividing roller, the roller of the dividing roller can roll, so that the smaller material can fall through the gap between the rollers, and at the same time, the larger material is directly transported to the left along the roller to the material distribution trolley, so that the operation of graded and layered material distribution can be realized, and the material jamming can be avoided, so that the material distribution effect is better.

[0031] like Figure 1-8As shown, the present invention provides a material distributing mechanism that is convenient for grading and stratifying, including a material distributing trolley 1 and a mixing trough 2. By setting the mixing trough 2, pre-storage of materials of different sizes can be achieved. Two alarms 13 are fixedly installed on the upper right side of the outside of the mixing trough 2. A discharging device 3 is installed at the discharging port position on the lower right side of the mixing trough 2. The discharging device 3 is located above the material distributing roller 4. The material distributing roller 4 is located above the material distributing roller 5. By setting the material distributing roller 5, and the material distributing roller 5 is assembled by multiple rollers, and the multiple rollers are rotatably connected to the two mounting plates, when the material falls on the material distributing roller 5, the material is distributed. The rollers of the material roller 5 can be rolled, so that smaller materials can fall through the gap between the rollers, and at the same time, larger materials are directly transported to the left along the rollers to the material distributing trolley 1, so that the operation of graded and layered material distributing can be realized, and at the same time, material jamming can be avoided, so that the material distributing effect is better. Two conical plates 7 are provided below the material distributing roller 5 and are located above the material distributing trolley 1. By setting the conical plates 7 and the conical shape of the conical plates 7, the materials can be smoothly arranged on the material distributing trolley 1. The two conical plates 7 are both equipped with a material distributing device 9, and the material distributing plates 97 on both sides are operated by the material distributing device 9 at the same time. The step-by-step reciprocating action enables the material-dividing plates 97 on both sides to realize the leveling operation of larger materials, and at the same time, it can also realize the leveling processing of materials after large and small fabrics, so that the materials can be evenly distributed on the fabric trolley 1, avoiding the problem of uneven fabric caused by excessive or insufficient local materials. The two conical plates 7 are fixedly connected by two connecting strips 8. By setting the connecting strip 8, the connecting strip 8 can connect the two conical plates 7, thereby reinforcing the two conical plates 7. Switches 15 are installed on both sides of the upper inner wall of the conical plate 7, and a docking plate 11 is provided between the two switches 15. The bottom of the docking plate 11 A scraper plate 14 is fixedly installed, and multiple elastic structures 6 are embedded in the scraper plate 14. Through the elastic structure 6, the switch 15 and the alarm 13 are cooperated, so that the elastic force of the elastic structure 6 can be triggered when the material accumulation is too much or too little, so that the docking plate 11 presses the switch 15 to control the alarm 13 to realize the alarm reminder operation, which is convenient for relevant personnel to discover and adjust in time. In addition, when the thickness is uneven, the size of the discharge port can be controlled by the discharge device 3 to achieve the purpose of automatic adjustment, meeting the requirement of uniform cloth thickness. The two ends of the multiple elastic structures 6 are respectively fixedly connected to the two sides of the inner wall of the conical plate 7.

[0032] The material-dispensing device 9 includes two rotating shafts 96, one of which is fixedly connected to the output shaft of the motor 91. The two rotating shafts 96 are respectively located below the conical plate 7. The two rotating shafts 96 are connected by a transmission structure 92. By setting the transmission structure 92, and the transmission structure 92 is composed of a chain and two sprockets, power can be transmitted over a long distance, which facilitates the synchronous rotation of the two rotating shafts 96. A plurality of spiral grooves 911 are provided on the outside of the two rotating shafts 96. By providing the spiral grooves 911, the rotation of the rotating shaft 96 can be controlled by the spiral grooves 911. The control slide rod 910 moves back and forth, thereby smoothly controlling the forward and backward movement of the annular sleeve 99. The interiors of the multiple spiral grooves 911 are all slidably connected with the slide rods 910. One ends of the multiple slide rods 910 are respectively fixedly connected to multiple annular sleeves 99 mounted on the rotating shaft 96. The right ends of the multiple annular sleeves 99 are fixedly connected to the same movable plate 95. The bottom of the movable plate 95 is equipped with multiple material-diverting plates 97 distributed at the same distance. By setting the material-diverting plate 97, the shape of the material-diverting plate 97 is arc-shaped, so that the material can be evenly dispensed and flattened through the arc surface.

[0033] like Figure 1 As shown, the bottom of the conical plate 7 is located on the right side of the scraper plate 14 and a pressing roller 10 is installed. By setting the pressing roller 10, the pressing roller 10 can achieve material pressing processing by rolling, and further maintain the uniformity of the material. The placement height of the left conical plate 7 is lower than the height of the right conical plate 7.

[0034] like Figure 3 As shown, a controller 12 is installed between the two alarms 13 above the right side of the mixing tank 2. By setting the controller 12, the controller 12 is electrically connected to the switch 15, the alarm 13, the motor 91 and the electric hydraulic rod 32 through wires. The discharging device 3 includes an electric hydraulic rod 32, which is embedded and fixed in two fixing seats 31. By setting the fixing seats 31, the fixing seats 31 can achieve the purpose of installing and fixing the electric hydraulic rod 32. The two fixing seats 31 are fixedly connected to the right side of the mixing tank 2, and the front end of the electric hydraulic rod 32 is fixed. It is fixedly connected with a convex rod 35, and the bottom of the convex rod 35 is slidably connected to the arc groove 33. By setting the convex rod 35 and the arc groove 33, the convex rod 35 can control the discharge plate 34 through the arc groove 33 to achieve angle flipping when moving, thereby facilitating the discharge operation. The arc groove 33 is opened along the length of the roller body at the top of the discharge plate 34, and the two ends of the top of the discharge plate 34 are hinged to the mixing trough 2 through two hinges 36. By setting the hinge 36, the hinge 36 can ensure that the discharge plate 34 can flip the angle, and the position of the discharge plate 34 corresponds to the position of the discharge port of the mixing trough 2.

[0035] like Figure 6-Figure 8As shown, a fixing plate 93 is fixedly connected to the top of the motor 91. By setting the fixing plate 93, the fixing plate 93 can fix the position of the motor 91. One end of the fixing plate 93 is fixedly connected to the front side of the conical plate 7. The front and rear ends of the rotating shaft 96 are rotatably connected to two bearings 98. By setting bearings 98, the bearings 98 can ensure that the rotating shaft 96 can smoothly realize the rotation movement. The two bearings 98 are respectively clamped on the front and rear sides of the conical plate 7. The front and rear sides of the inner wall of the conical plate 7 are respectively fixedly connected to the two ends of the support rod 94. The outside of the support rod 94 is slidably connected with a sliding sleeve 912 corresponding to the number of the annular sleeve 99. By setting the support rod 94 and the sliding sleeve 912, the support rod 94 can guide the sliding sleeve 912 to ensure the smooth movement of the sliding sleeve 912, thereby The annular sleeve 99 can move smoothly, and multiple sliding sleeves 912 are respectively embedded in multiple annular sleeves 99. The elastic structure 6 includes a fixed rod 61. The two ends of the fixed rod 61 are respectively fixedly connected to the two sides of the inner wall of the conical plate 7. By setting the fixed rod 61, the fixed rod 61 can support the scraper plate 14 through the sleeve. The fixed rod 61 is slidably connected in the sleeve installed on the scraper plate 14. The right side of the sleeve is fixedly connected with a spring 62. By setting the spring 62, the elastic force of the spring 62 can produce deformation when the scraper plate 14 accumulates too much material, pressing the switch 15 to control the alarm 13 to alarm. At the same time, it can also push the scraper plate 14 to move when the material accumulation is less, which can trigger the alarm operation of the alarm 13 again. The right end of the spring 62 is fixedly connected to the right side of the inner wall of the conical plate 7.

[0036] A material distribution mechanism and a method for using the same for facilitating grading and layering, comprising the following steps:

[0037] S1. First, the electric hydraulic rod 32 is operated to drive the convex rod 35 to move, so that the convex rod 35 controls the roller body through the arc groove 33 to drive the discharge plate 34 to rotate. At this time, the discharge port of the mixing tank 2 is opened for discharging, so that the material falls through the distribution roller 4 for downward distribution. At the same time, the dividing roller 5 grades and screens the material. The larger material falls to the lower left along the dividing roller 5, while the smaller material falls directly from the roller of the dividing roller 5 onto the conical plate 7 and is dispersed along the conical plate 7 to the distribution trolley 1 moving to the right, and the larger material is pre-placed from the left side of the distribution trolley 1.

[0038] S2. When the large and small materials are placed on the material distribution trolley 1 respectively, the control motor 91 drives the rotating shaft 96 to rotate. Under the action of the transmission structure 92, the two rotating shafts 96 rotate synchronously, so that the rotating shaft 96 squeezes the spiral groove 911 to control the slide bar 910 to reciprocate along the spiral groove 911, so that the slide bar 910 drives the annular sleeve 99 and the movable plate 95 to reciprocate back and forth, so that the movable plate 95 drives the material stripping plate 97 to reciprocate back and forth, so that the material stripping plate 97 flattens the large and small materials;

[0039] S3. During the process of the material being conveyed to the right by the distribution trolley 1, the scraper plate 14 can accumulate excess material. When too much material is accumulated, the spring 62 is deformed, causing the scraper plate 14 to drive the docking plate 11 to move to the right and press the switch 15. At this time, the switch 15 can control the alarm 13 to sound an alarm. At the same time, the controller 12 controls the electric hydraulic rod 32 to drive the convex rod 35 to move, so that the convex rod 35 drives the discharge plate 34 to rotate through the arc groove 33 to reduce the angle with the discharge port and reduce the discharge. When the scraper plate 14 accumulates less material, the elastic force of the spring 62 controls the docking plate 11 through the scraper plate 14 to press the left switch 15. At this time, the alarm is sounded again and the discharge of the discharge port is increased. At the same time, when the material is conveyed to the right, the pressing roller 10 flattens the material so that the larger material is located in the lower layer and the smaller material is located in the upper layer of the larger material to achieve uniform distribution operation.

At the same time, when the material is transported to the right, the pressing roller (10) flattens the material so that the larger material is located at the lower layer and the smaller material is located at the upper layer of the larger material to achieve uniform material distribution.
