Description

Technical Field

[0001] The invention relates to the technical field of cementitious material storage and transportation, in particular to cementitious material storage and transportation equipment on an asphalt concrete mixing building. Background Art

[0002] In modern concrete mixing plant technology, various sands, gravels, cementitious materials and auxiliary materials need to be mixed and stirred to provide various needs of the construction site. Cementitious materials account for a large proportion of them. In concrete mixing plants, the amount of cementitious materials used is relatively large, so the storage and transportation of cementitious materials are more important.

[0003] Published document CN115649589A discloses a cementitious material storage and conveying system for use in a concrete mixing plant, comprising a fixed frame, a rotating component for cutting and collecting cement bags, a conveying component for conveying cement bags, and an auxiliary component. The rotating component comprises two support rods arranged on the fixed frame, a first rotating groove provided on the upper part of the support rods, a first conveying shaft provided in the first rotating groove, a protective cover provided between the support rods, a plurality of cutting knives provided in the protective cover, a shaking bin provided on one side of the protective cover, a first circular groove provided on both sides of the shaking bin, and a bidirectional rotating shaft provided in the shaking bin. This solves the problem that cementitious materials require multiple back-and-forth operations during transportation, the storage volume is too small to affect work efficiency, automation cannot be achieved, and work efficiency is reduced.

[0004] The above scheme proposes to separate cement and cement bags during the transportation of bagged cement in order to improve work efficiency. The scheme for separating the packaging bags in this scheme is to use a crescent blade to wrap the cut cement bag, so as to achieve the effect of separating the cement bag and cement. However, in actual operation, we found that when the crescent blade wraps the cement bag, the wrapped cement bag will be tightly wrapped with a large amount of cement, resulting in waste of cement raw materials and poor separation effect of cement and cement bag. In addition, during the bag removal process, when the crescent blade wraps the cement bag, the blade head will hang on the bag, and the cement bag will be entangled between multiple blades. It is difficult to separate the cement bag by simply reversing the crescent blade. In particular, multiple cement bags will be entangled in this scheme, resulting in poor bag removal effect.

The four movable sleeves 8 are all slidably connected to the inside of the cross slide 4, and the first threaded rod 7 passes through the movable sleeve 8 and is connected to the movable sleeve The first and second bevel gears 29 are meshed with each other, so that the rotating ring 25 drives the first bevel gear 27 and the second bevel gear 29 to rotate, thereby driving the rotating rod 28 and the rotating sleeve 9 to rotate. The four corners of the cross slide 4 are fixedly connected to the forward and reverse motors 34, and the output ends of the four forward and reverse motors 34 are fixedly connected to the four first threaded rods 7 respectively.

[0023] A rotating sleeve 9 is provided at the bottom of the movable sleeve 8, and a second threaded rod 10 is slidably connected inside the rotating sleeve 9. The bottom end of the rotating rod 28 is fixedly connected to the top of the rotating sleeve 9. An L-shaped plate 30 is fixedly connected to one side of the bottom of the movable sleeve 8. The bottom end of the L-shaped plate 30 is fixedly connected to a threaded sleeve 31. The second threaded rod 10 passes through the threaded sleeve 31 and is threadedly connected to the threaded sleeve 31. Vertical plates 33 are formed on both sides of the rotating sleeve 9. The two vertical plates 33 are respectively adapted to the two vertical grooves 32. The vertical grooves 32 are limited by the vertical plates 33, driving the second threaded rod 10 and the rotating sleeve 9 to rotate synchronously. At the same time, it does not affect the second threaded rod 10 in the rotating sleeve. The inside of the cylinder 9 slides up and down, and the bottom end of the second threaded rod 10 is fixedly connected to a protective sleeve 11. Push blocks 12 are provided on both sides of the bottom of the protective sleeve 11. The opposite sides of the two push blocks 12 are fixedly connected to a splint 15. The tops of the two push blocks 12 are fixedly connected to a slide plate 13. Both sides of the bottom of the protective sleeve 11 are fixedly connected to the limited position rails 14. The two slide plates 13 are respectively slidably connected to the inside of the two limited position rails 14. The inside of the protective sleeve 11 is fixedly connected to an electric push rod 16. The output end of the electric push rod 16 is fixedly connected to a pull plate 17. The pull plate 17 passes through the bottom of the protective sleeve 11 and is slidably connected to the protective sleeve 11. The bottom of the pull plate 17 is fixedly connected on both sides. A guide rod 18 is connected, and a guide groove 19 is provided inside the two push blocks 12. The two guide rods 18 respectively penetrate the two guide grooves 19 and are slidably connected to the two guide grooves 19. A slide groove 20 is provided inside the opposite side of the two push blocks 12. The two slide grooves 20 are respectively connected to the two guide grooves 19. A hanging plate 21 is slidably connected inside the two slide grooves 20. The two guide rods 18 correspond to the two hanging plates 21 respectively. A spring 22 is fixedly connected to the top of the slide groove 20. One end of the spring 22 is fixedly connected to the hanging plate 21. Limit plates are formed on both sides of the hanging plate 21. The two limit plates are slidably connected to the push blocks 12 The two sides of the interior are conducive to limiting the hanging plate 21, so that the hanging plate 21 can maintain horizontal movement inside the push block 12. Blades 23 are provided on both sides of the hanging plate 21, and the two blades 23 are fixedly connected to the side of the push block 12 away from the splint 15. The bags tied to the outside of the push block 12 can be cut by the blades 23 to prevent entanglement. A first dust cover 45 is fixedly connected to the top of the lifting bin 1, and the first dust cover 45 is arranged on the top of the blanking tooth plate 2. A second dust cover 46 is fixedly connected to the top of the fixing frame 3, and the second dust cover 46 is arranged on the outside of the fixing frame 3 and the bag recovery box 39 to prevent dust from flying and improve the working environment.

[0024] When this solution is in use, the bagged cement is placed on the conveyor belt 44, and the cement is transferred to the inside of the receiving box 43 through the conveyor belt 44 and falls on the top of the lifting tooth plate 42. The chain transmission system 41 is started to drive the lifting tooth plate 42 to rise, and the cement is lifted to the top of the lifting bin 1. The rotation trajectory of the chain transmission system 41 will drive the lifting tooth plate 42 to move to the top of the chain transmission system 41 and then deflect backward, so that the lifting tooth plate 42 flips the cement bag backward, and the cement bag falls above the blanking tooth plate 2 and rolls down from the inclined surface of the blanking tooth plate 2, so that the cement bag falls inside the fixed frame 3, which is conducive to the subsequent cutting and bagging operations of the cement bag. After the cement bag falls, the lifting tooth plate 42 and the blanking tooth plate 2 intersect, so that the lifting tooth plate 42 returns to circulate.

[0025] One side of the fixed frame 3 is fixedly connected to a bag recovery box 39, and the four corners of the bottom of the cross slide 4 are fixedly connected to a movable plate 35. The fixed frame 3 and the top of the bag recovery box 39 are fixedly connected to electric guide rails 36. The four movable plates 35 are slidably connected to the outside of the two electric guide rails 36. The moving ends of the two electric guide rails 36 are fixedly connected to the four movable plates 35, driving the movable plates 35 to move, thereby driving the cross slide 4 to move on the top of the fixed frame 3 and the bag recovery box 39. The two sides of the bottom of the fixed frame 3 are hinged with a material blocking plate 47, and the bottom of the fixed frame 3 is fixedly connected to a storage bin 37. The inside of the storage bin 37 is hinged with two second hydraulic cylinders 48 on both sides. The four second hydraulic cylinders 4 8 output ends are hinged to the bottom of the two baffle plates 47 respectively, and the bottom of the storage bin 37 is fixedly connected to a stand 38, which is convenient for controlling the opening and closing of the electric guide rail 36 to put down the cement. The rear side of the interior of the lifting bin 1 is fixedly connected to a support plate 40, and a chain transmission system 41 is installed on the outside of the support plate 40. A lifting tooth plate 42 is fixedly connected to the outside of the chain transmission system 41, and the lifting tooth plate 42 is set to be tooth-shaped. The lifting tooth plate 42 is adapted to the blanking tooth plate 2. The bottom of the lifting bin 1 is fixedly connected to a material receiving box 43, and the material receiving box 43 is set to be hollow. The lifting tooth plate 42 is adapted to the internal cavity of the material receiving box 43, which is convenient for driving the lifting tooth plate 42 to move according to the moving trajectory of the chain transmission system 41 to lift the cement bag.

[0026] After the cement bag falls into the fixed frame 3, the movable plate 35 is driven by the electric guide rail 36 to move horizontally, thereby driving the cross slide 4 to move above the fixed frame 3, and the first hydraulic cylinder 5 is started to drive the cross cutter 6 to descend, and the cross cutter 6 is inserted into the cement bag, and a cross-shaped opening is opened above the cement bag. The blade direction of the cross cutter 6 is staggered with the four protective sleeves 11, and then the four forward and reverse motors 34 are started to drive the first threaded rod 7 to rotate, driving the four movable sleeves 8 to move toward the middle at the same time. The movement of the movable sleeve 8 corresponds to the movement of the second threaded rod 10. When the first threaded rod 7 drives the movable sleeve 8 to move, the limit grooves 24 opened on both sides of the first threaded rod 7 limit the limit blocks 26, driving the rotating ring 2 5 rotates inside the movable sleeve 8, and at the same time, the rotating ring 25 drives the first bevel gear 27 to rotate, so that the first bevel gear 27 drives the second bevel gear 29 to rotate, and then the second bevel gear 29 drives the rotating rod 28 and the rotating sleeve 9 to rotate. When the rotating sleeve 9 rotates, it drives the vertical plate 33 to rotate, so that the vertical plate 33 drives the second threaded rod 10 and the rotating sleeve 9 to rotate synchronously. The second threaded rod 10 is threadedly connected with the threaded sleeve 31, so when the second threaded rod 10 rotates when it descends, the second threaded rod 10 drives the protective sleeve 11 to rotate and descend, so that the protective sleeve 11 drives the push block 12 and the clamping plate 15 to fall on the cement bag. Because the cross cutter 6 is located in the center of the four protective sleeves 11, each group of clamping plates 15 in the four directions is aligned with the cross opening being cut. The four bag corners correspond to each other, and the electric push rod 16 is used to start the pulling plate 17 to rise. When the pulling plate 17 rises, it drives the guide rod 18 to rise, so that the guide rods 18 on both sides slide along the guide groove 19, pushing the two opposite pushing blocks 12 close to each other and clamping the broken corners of the cement bag. When the guide rod 18 moves inside the guide groove 19, it will also push the hanging plate 21 inside the pushing block 12 to move outward, so that the hanging plate 21 extends from the inside of the pushing block 12, and after clamping the four corner bags of the broken hole, the forward and reverse motors 34 are started in the reverse direction to rotate the four first threaded rods 7 in the opposite direction, and drive the four movable sleeves 8 to move back, and at the same time drive the rotating sleeve 9 to reverse. When the rotating sleeve 9 is reversed, the rotating sleeve 9 drives the second threaded rod 10 and the protective The sleeve 11 is reversed and rises under the limit of the threaded sleeve 31. Since the cross cutter 6 is still inserted into the cement and in contact with the cement to support the cement, the protective sleeve 11 drives the multiple clamping plates 15 to pull the clamped bag corners in four directions, and lifts upward while pulling, increasing the pulling angle and distance, so that the bag is completely spread out. In the process of movement and rotation of the clamping plates 15, the push block 12 will wrap the bag corners around the outside of the push block 12, and at the same time, the extension of the hanging plate 21 will just wrap the bag corners around the outside of the hanging plate 21. Due to the groove design of the hanging plate 21, the bag corners will not slip after being wrapped inside the groove, preventing the bag corners from falling off from the push block 12, which is beneficial to prevent the bag corners from slipping and affecting the bag pulling effect during the process of tearing open the cloth bag, and controlling the first hydraulic cylinder 5 to drive in the reverse direction.The first hydraulic cylinder 5 drives the cross cutter 6 to separate from the cement, which is conducive to opening the outer packaging bag of the bagged cement, making it convenient for the cement to be directly stored in the storage bin 37 and convenient for subsequent mixing processing.

[0027] The two sets of electric push rods 16 away from the bag recovery box 39 are controlled to drive in reverse, so that the pull plate 17 is lowered and the two push blocks 12 move in the opposite direction, so that the push blocks 12 drive the splints 15 to separate and loosen the bag corners. In the process of the push blocks 12 moving outward, the hanging plates 21 are opened outward during the bag pulling process, and the push blocks 12 are reset at this time, so that the hanging plates 21 are retracted into the inside of the push blocks 12, but the overall support distance for the bag corners does not change, but the push blocks 12 replace the hanging plates 21 to support the bag corners, so the bag corners will not be tied too tightly and the push blocks 12 will not be able to be opened. Because the push block 12 lacks grooves or other locations where bag corners can hang, the weight of the cement can cause the bag corners to slip off the outside of the push block 12. However, the blades 23 fixed to the outside of the push block 12 cut through the tight corners as they move outward, preventing them from getting caught. At this point, the two corners of the cement bag near the storage bin 37 remain clamped, while the two corners near the drop plate 2 are lowered. The second hydraulic cylinder 48 opens the retaining plate 47, allowing the cement to fall from the interior of the fixed frame 3 into the storage bin 37 for storage, eliminating the need for manual removal of the cement bags. The system automatically completes the bag unpacking operation, saving significant labor and time. This automated technology significantly improves work efficiency, making the entire production process more efficient and smoother. This reduces the physical effort and time required to unpack heavy cement bags, thereby reducing their workload. Furthermore, the automated bag unpacking system significantly reduces potential errors and delays during production, ensuring smooth production progress.

[0028] When the cement is stored, the electric guide rail 36 drives the cross slide 4 to move to the top of the bag recovery box 39, completely loosens the four corners of the cement bag, and puts the cement bag into the bag recovery box 39 for storage, which is convenient for subsequent centralized recycling and processing. In addition, the first dust cover 45 and the second dust cover 46 can prevent dust from flying and polluting the working environment.
