Abstract
Description
Technical Field
[0001] This invention relates to the field of conveying equipment technology, and in particular to a material conveying equipment for cement production. Background Technology
[0002] The cement production process involves the long-distance, multi-point continuous transportation of various bulk materials such as limestone, raw materials, clinker, blended materials, and crushed stone. Traditional conveying equipment relies heavily on manual inspection, on-site start-up and shutdown, and segmented scheduling, which has problems such as high dust, high energy consumption, easy blockage and deviation, and delayed scheduling response.
[0003] As the cement industry upgrades towards green and intelligent manufacturing, there is an urgent need for reduced-manpower and unmanned operations in raw material storage yards and conveying processes. Traditional equipment struggles to coordinate with the plant's intelligent scheduling system, failing to meet the production requirements of precise coal blending, uniform material collection, and stable material supply. To address these shortcomings, this invention proposes a novel material conveying equipment for cement production. By integrating an unmanned storage yard intelligent control system, it achieves fully automated coordination of material stacking and reclaiming, transfer, metering, dust removal, and safety protection, improving conveying stability and intelligence while reducing manual intervention and maintenance costs. Summary of the Invention
[0004] To overcome the aforementioned shortcomings of the prior art, the present invention provides a material conveying device for cement production in unmanned storage yards, capable of precise quantitative feeding: This invention provides a material conveying device for cement production, including a trolley. A hydraulic jack extending horizontally towards the front end of the trolley is fixed to the trolley's front end. A shaped support fork is fixed to the end of the hydraulic jack's extension rod. A horizontal shaped groove is pre-drilled at the top of the shaped support fork, and a first conveyor frame capable of sliding up and down is engaged within the groove. A second conveyor frame is rotatably connected to the bottom end of the first conveyor frame, and the first and second conveyor frames share a reinforcing conveyor belt. Equally spaced through-shafts traverse the middle of the reinforcing conveyor belt, and equally spaced composite hoppers are arranged on the surface of the reinforcing conveyor belt. Each composite hopper includes an outer shell with an upward-opening, overall digging-like structure. The outer casing has a trapezoidal perforation at one end. An inner hopper is slidably connected to the inner wall of the outer casing, and a hinged bottom plate is hinged to the bottom of the inner hopper. A pushing mechanism is provided on the side of the conveyor frame near the top and away from the trapezoidal perforation to push the inner hopper to the unloading position for unloading. A receiving module is provided on the side of the conveyor frame opposite to the pushing mechanism. Through the composite hopper and the inner hopper sliding inside it, the amount of material unloaded each time can be kept within a stable range, so that the final unloading volume is controllable. The feeding process can be stopped and resumed at any time. The whole structure adopts a vertical lifting method, which can greatly save space and equipment maintenance costs.
[0005] A further feature of this invention is that the bottom end of the shaped support fork arm is fixed with guide slide rods that are parallel to each other and parallel to the hydraulic jack rod on both sides. The front end of the trolley is fitted with a wear-resistant slip ring that matches the diameter of the guide slide rod. A counterweight is provided at the end of the trolley away from the shaped support fork arm. The counterweight can automatically adapt to a suitable distance according to the size of the stockpile, thereby improving loading efficiency and avoiding the phenomenon of empty digging when the composite hopper is digging.
[0006] A further feature of this invention is that the conveyor frame includes two parallel and vertical side guard strips, with a common drive roller between the top ends of the two side guard strips. Adjustment sliding strips are fixed to the bottom of the opposing sides of the two side guard strips of the conveyor frame. Adaptation grooves for the adjustment sliding strips are pre-reserved on the inner walls of the opposing sides of the shaped grooves of the shaped support fork. Positioning mechanisms are provided near the adaptation grooves on the shaped support fork. With the help of these positioning mechanisms, the overall height can be adjusted according to the height of the stockpile for efficient digging and conveying.
[0007] A further feature of this invention is that the receiving module includes a shaped support rod fixed to one side of the conveyor frame near the top. Two coaxial sliding bearings of equal height are embedded at the end of the shaped support rod away from the conveyor frame. A round rod is slidably connected to each of the two sliding bearings, and the same side fixing block is fixed at the end of each round rod away from the rising path of the composite hopper. A receiving hopper with an upward opening is fixed at the top of the side fixing block, and a return spring is fixed between the side fixing block and the sliding bearing. An inclined surface is provided on the side of the receiving hopper near the rising path of the composite hopper, and the midpoint of the inclined surface coincides with the side of the composite hopper near the trapezoidal perforation. During use, when the loaded composite hopper rises, it pushes the inclined surface of the receiving hopper, thus pushing it to one side. When the composite hopper rises above the top opening of the receiving hopper, the receiving hopper will move slightly to one side of the composite hopper. At this point, pushing the inner hopper to unload helps prevent spillage.
[0008] A further feature of this invention is that the second conveyor frame includes a front side plate and a rear side plate, and the front side plate and the rear side plate are respectively rotatably connected to the sides of two side guard strips of the first conveyor frame near the bottom. A common conveying roller is provided at the junction of the first and second conveyor frames. A worm gear ring is fixed to the end of the front side plate near the conveying roller, and a hinge frame is fixed to the front side of the first conveyor frame near the bottom. An adjusting worm gear that meshes with the worm gear ring is rotatably connected to the hinge frame. The two side guard strips of the first conveyor frame... The slats are fixed with symmetrical, oppositely opening arc-shaped guide rails on the side closest to the bottom and furthest from the trolley. The protruding ends of the through shafts on both sides of the reinforcing conveyor belt pass through the arc-shaped guide rails on their respective sides as the reinforcing conveyor belt moves forward. By adjusting the worm gear and the arc-shaped guide rails that bend away from the trolley, the inclination of the second conveyor frame can be adjusted according to the size and steepness of the material pile during feeding, thereby improving the filling efficiency of the composite hopper waiting to be fed below the second conveyor frame.
[0009] A further feature of this invention is that the side of the outer casing near the reinforcing conveyor belt is a sloping side, and two triangular ribs are pre-reserved on the outer wall of the outer casing near the sloping side. The length of the right-angled side of the triangular rib is equal to the distance between two adjacent through shafts. The upper and lower ends of the outer casing near the triangular ribs are respectively fixed with a hinge lug 1 and a spring support block. Each spring support block is fixed with a tension spring, and the end of each tension spring near the reinforcing conveyor belt is fixed with a hinge lug 2. The hinge lug 1 and hinge lug 2 are respectively slidably sleeved on two adjacent through shafts, so that when the composite hopper passes through a bend, the side near the bottom of the hopper can be tightly attached to the surface of the reinforcing conveyor belt and can be reset in time.
[0010] A further feature of this invention is that the inner box includes a vertical side plate and an inclined side plate that fits against the sloping side. A sliding groove penetrating both ends is provided in the middle of the sloping side of the outer casing and the inner wall opposite it. The outer walls of the vertical side plate and the inclined side plate are respectively provided with guide slides one and two, which are longer than the length of the inner box. The top of the end of the inner box away from the trapezoidal perforation is provided with an upwardly protruding limiting protrusion. By providing guide slides one and limiting protrusions that are longer than the inner box, the inner box can be prevented from being pushed out as a whole or from warping and misaligning and being unable to return to its original position during material discharge.
[0011] A further feature of this invention is that an inner liner plate is fixed to the inner wall of the inner hopper near the limiting protrusion, and a permanent magnet is embedded in the middle of the inner liner plate. The outer shell and the inner hopper are respectively provided with combination hole two and combination hole one with a diameter larger than that of the permanent magnet at their ends near the permanent magnet. Reset springs are fixed to both sides of the inner liner plate away from the receiving hopper and on both sides of the permanent magnet. Spring baffles are fixed to both the two reset springs through combination hole two and combination hole one. The spring baffles are fixed to the ends of the outer shell. The pushing mechanism includes a shaped support rod two fixed to the side of the conveyor frame one near the top, and an electromagnet is fixed to the upper surface of the shaped support rod two, which is adapted to the position of the permanent magnet when it runs to the unloading position. When the inner hopper needs to be pushed out for unloading, the electromagnet is energized only when the composite hopper rises to the height of the electromagnet. When the inner hopper is just pushed out, the hinged bottom plate will not rotate immediately. It will only rotate when the inner hopper is pushed out to its maximum, allowing the internal material to leak out.
[0012] A further feature of the present invention is that the bottom of the outer casing and the inner box are respectively provided with a strip-shaped leakage hole two and a strip-shaped leakage hole one at the end near the second combination hole. This helps to ensure that the inner box and the outer casing are not blocked by debris during use, and allows the leaked debris to be expelled as soon as possible.
[0013] A further feature of this invention is that the bottom of the inner hopper has an opening, and the end of the inner hopper near the inner liner plate has a coaxial hinge hole near the opening. One end of the hinge base plate has two coaxial short shafts that are inserted into the corresponding hinge holes. The entire hinge base plate is made of elastic material, and the middle of the hinge base plate arches upward when not under stress. This ensures that the material is unloaded only after the top opening of the receiving hopper completely covers the inner hopper, reducing the probability of spillage.
[0014] The beneficial effects of this invention are as follows: 1. By using a composite hopper and an inner hopper that slides inside, the amount of material discharged each time can be kept within a stable range, thus making the final discharge volume controllable. The feeding process can be stopped and resumed at any time, and the overall vertical lifting method can greatly save on site and equipment maintenance costs.
[0015] 2. Because of the inclined receiving hopper, when the loaded composite hopper rises during use, it will push the inclined surface of the receiving hopper and push it to one side. When the composite hopper rises above the top opening of the receiving hopper, the receiving hopper will move slightly to one side of the composite hopper. At this time, pushing the inner hopper to unload helps to prevent spillage.
[0016] 3. By using the electromagnet and permanent magnet, when it is necessary to push out the inner hopper for unloading, simply energize the electromagnet when the composite hopper rises to the height of the electromagnet. The hinged bottom plate will not rotate immediately when the inner hopper is pushed out. It will only rotate when the inner hopper is pushed out to its maximum extent, allowing the material inside to leak out. Attached Figure Description

Detailed Implementation
[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0020] In this embodiment, refer to Figures 1-11A material conveying device for cement production includes a trolley 1. A hydraulic jack 3 extending horizontally towards the front end of the trolley 1 is fixed to the front end. A Y-shaped support fork 4 is fixed to the end of the extension rod of the hydraulic jack 3. A horizontal U-shaped slot is pre-reserved at the top of the Y-shaped support fork 4, and a conveyor frame 10 capable of sliding up and down is engaged within the U-shaped slot. A second conveyor frame 15 is rotatably connected to the bottom end of the first conveyor frame 10. The first and second conveyor frames 10 and 15 share a reinforcing conveyor belt 13. Equally spaced through shafts 14 traverse the middle of the reinforcing conveyor belt 13. Equally spaced composite hoppers 11 are arranged on the surface of the reinforcing conveyor belt 13. The composite hopper 11 includes an outer shell 1101 with an upward-opening, bucket-shaped structure. One end of 1 has a trapezoidal perforation 1113. The inner box 1102 is slidably connected to the inner wall of the outer casing 1101, and the bottom of the inner box 1102 is hinged to a hinged base plate 1112. A pushing mechanism is provided on the side of the conveyor frame 10 near the top and away from the trapezoidal perforation 1113. This mechanism is used to push the inner box 1102 to the unloading position for unloading. A receiving module is provided on the side of the conveyor frame 10 opposite to the pushing mechanism. Through the composite hopper 11 and the inner box 1102 sliding inside it, the amount of material unloaded each time can be kept within a certain range, so that the final unloading amount is controllable. The feeding process can be stopped and continued at any time. The whole adopts a vertical lifting method, which can greatly save space and equipment maintenance costs.
[0021] Reference Figure 1 The bottom end of the Y-shaped support fork arm 4 is located on both sides of the hydraulic jack 3, and guide slide rods 18 that are parallel to each other and parallel to the hydraulic jack 3 are fixed respectively. The front end of the cargo trolley 1 is fitted with a wear-resistant slip ring that matches the diameter of the guide slide rod 18. A counterweight block 2 is set at the end of the cargo trolley 1 away from the Y-shaped support fork arm 4. Through the counterweight block 2 and the hydraulic jack 3, the appropriate distance can be automatically adapted according to the size of the stockpile, thereby improving the loading efficiency and avoiding the phenomenon of empty digging when the composite hopper 11 is digging.
[0022] Reference Figure 1 and Figure 4 The conveyor frame 10 includes two parallel and vertical side guard strips, and the same drive roller 9 is provided between the top ends of the two side guard strips. The two side guard strips of the conveyor frame 10 are fixed with height adjustment side slides 5 near the bottom on opposite sides. The inner walls of the opposite sides of the U-shaped slot of the Y-shaped support fork arm 4 are reserved with matching grooves that are adapted to the height adjustment side slides 5. The Y-shaped support fork arm 4 is provided with a positioning mechanism near the matching groove. By using the height adjustment side slides 5 and the positioning mechanism, the overall height can be adjusted according to the height of the stockpile for efficient digging and conveying.
[0023] Reference Figure 1 , Figure 3 and Figure 5 The receiving module includes an L-shaped support rod 7 fixed to the side of the conveyor frame 10 near the top. Two coaxial sliding bearings 604 of equal height are embedded at the end of the L-shaped support rod 7 away from the conveyor frame 10. A round rod 603 is slidably connected to each of the two sliding bearings 604. The same side fixing block 601 is fixed at the end of the two round rods 603 away from the rising path of the composite hopper 11. The top of the side fixing block 601 is fixed with an upward-opening receiving hopper 6. A return spring 602 is fixed between the side fixing block 601 and the sliding bearing 604. The receiving hopper 6 has an inclined surface on one side of the rising path of the composite hopper 11, and the midpoint of the inclined surface coincides with the side of the composite hopper 11 near the trapezoidal perforation 1113. With this arrangement, when the loaded composite hopper 11 rises during use, it will push the inclined surface of the receiving hopper 6 and push it to one side. When the composite hopper 11 rises above the top opening of the receiving hopper 6, the receiving hopper 6 will move slightly to one side of the composite hopper 11. At this time, pushing the inner box hopper 1102 to unload the material helps to prevent spillage.
[0024] Reference Figure 1 , Figure 2 and Figure 4 Conveyor frame 2 15 includes a front side plate and a rear side plate, which are rotatably connected to the sides of two side guard strips of conveyor frame 1 10 near the bottom. A common conveying roller is provided at the junction of conveyor frame 1 10 and conveyor frame 2 15. A worm gear ring 16 is fixed to one end of the front side plate near the conveying roller. A hinge frame is fixed to the front of conveyor frame 1 10 near the bottom, and an adjusting worm 17 that meshes with the worm gear ring 16 is rotatably connected to the hinge frame. The two side guard strips of conveyor frame 1 10 are near the bottom and away from the load. One side of the trolley 1 is fixed with symmetrical arc-shaped guide rails 12 with opposite openings. The ends of the through shafts 14 protruding from both sides of the reinforcing conveyor belt 13 will pass through the arc-shaped guide rails 12 on their respective sides as the reinforcing conveyor belt 13 moves forward. By setting the adjusting worm gear 17 and the arc-shaped guide rails 12 that bend away from the trolley 1, the inclination of the second conveyor frame 15 can be adjusted according to the size and steepness of the material pile during feeding, thereby improving the filling efficiency of the composite hopper 11 waiting to be fed below the second conveyor frame 15.
[0025] Reference Figures 6-11The outer casing 1101 has a sloping side near the reinforcing conveyor belt 13, and two triangular rib plates 1108 are reserved on the outer wall of the outer casing 1101 near the sloping side. The length of the right angle side of the triangular rib plate 1108 is equal to the distance between two adjacent through shafts 14. The upper and lower ends of the outer casing 1101 near the triangular rib plate 1108 are respectively fixed with a hinge ear 1103 and a spring support block. Each spring support block is fixed with a tension spring 1109, and the end of the tension spring 1109 near the reinforcing conveyor belt 13 is fixed with a hinge ear 2 1110. The hinge ear 1103 and the hinge ear 2 1110 are respectively slidably sleeved on two adjacent through shafts 14. By setting up a composite hopper 11 with tension springs 1109, the composite hopper 11 can be tightly attached to the surface of the reinforcing conveyor belt 13 near the bottom when passing through the bend, and can be reset in time.
[0026] Reference Figures 6-11 The inner box 1102 includes a vertical side plate 1102a and an inclined side plate 1102b that fits against the sloping side. The inclined side of the outer casing 1101 and the inner wall opposite it are both provided with a through groove 1114. The outer walls of the vertical side plate 1102a and the inclined side plate 1102b are respectively reserved with guide slides 1102c and 1102d, which are longer than the length of the inner box 1102. The top of the end of the inner box 1102 away from the trapezoidal through hole 1113 is reserved with an upwardly protruding limiting protrusion 1102e. By setting the guide slides 1102c and the limiting protrusion 1102e, which are longer than the inner box 1102, the inner box 1102 can be prevented from being pushed out as a whole or from warping and misaligning and being unable to return to its original position when discharging.
[0027] Reference Figures 6-11An inner liner 1104 is fixed to the inner wall of the inner hopper 1102 near the limiting protrusion 1102e, and a permanent magnet 1105 is embedded in the middle of the inner liner 1104. The outer casing 1101 and the inner hopper 1102 near the permanent magnet 1105 have combination holes 1107 and 1102g respectively, with diameters larger than the permanent magnet 1105. Return springs 1106 are fixed to both sides of the inner liner 1104 away from the receiving hopper 6 and on both sides of the permanent magnet 1105. Spring baffles 1115 are fixed to both return springs 1106 passing through combination holes 1107 and 1102g. All 5 are fixed to the end of the outer casing 1101. The pushing mechanism includes an L-shaped support rod 2 19 fixed to the side of the conveyor frame 10 near the top. An electromagnet 8 is fixed on the upper surface of the L-shaped support rod 2 19, which is adapted to the position of the permanent magnet 1105 when it runs to the unloading position. With this setting, when the inner box hopper 1102 needs to be pushed out for unloading, the electromagnet 8 can be energized only when the composite hopper 11 rises to the height of the electromagnet 8. When the inner box hopper 1102 is pushed out, the hinged bottom plate 1112 will not rotate immediately. It will only rotate when the inner box hopper 1102 is pushed out to the maximum, so that the material inside will fall out.
[0028] Reference Figures 6-11 The bottom of the outer casing 1101 and the inner box 1102 near the second combination hole 1107 are respectively provided with a strip-shaped leakage hole 1111 and a strip-shaped leakage hole 1102f, which helps to ensure that the inner box 1102 and the outer casing 1101 are not blocked by debris during use, and allows the leaked debris to be expelled as soon as possible.
[0029] Reference Figures 10-11 The bottom of the inner hopper 1102 is reserved with an opening, and the end of the inner hopper 1102 near the inner liner plate 1104 has a coaxial hinge hole 1102h near the opening. One end of the hinge base plate 1112 is reserved with two coaxial short shafts that are inserted into the corresponding hinge holes 1102h. The entire hinge base plate 1112 is made of elastic material, and the middle of the hinge base plate 1112 arches upward when it is not under stress. With this setting, it can be ensured that the material will not be discharged until the top opening of the receiving hopper 6 completely covers the inner hopper 1102, reducing the probability of spillage.
[0030] Working Principle: When using this device, firstly, adjust the height of conveyor frame 10 according to the height of the unmanned storage yard. Then, rotate the adjusting worm gear 17 to control the tilt angle of conveyor frame 15, so that the composite hopper 11 below conveyor frame 15 is aligned with the slope of the storage yard for shoveling material. Finally, align the discharge port of receiving hopper 6 with the material receiving position. Then, control the drive roller 9 to rotate, driving the reinforcing conveyor belt 13 to start running. At this time, the composite hopper 11 below conveyor frame 15 is filled sequentially and then conveyed to the side of conveyor frame 10 near receiving hopper 6. Once the composite hopper 11 has moved to the side near receiving hopper 6... When the material is below 6, it will push the inclined surface of the receiving hopper 6 and then push it to one side. When the composite hopper 11 rises above the top opening of the receiving hopper 6, the receiving hopper 6 will move slightly to one side of the composite hopper 11. When the composite hopper 11 has moved completely above the receiving hopper 6, it will stop. At this time, the electromagnet 8 is energized to generate a repulsive force against the end of the permanent magnet 1105. When the inner box hopper 1102 is just pushed out, the hinged bottom plate 1112 will not rotate immediately. It will only rotate when the inner box hopper 1102 is pushed out to its maximum, and then the material inside will leak into the receiving hopper 6. This cycle continues until the required amount is filled and then stops.
[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
