Description

Technical Field

[0001] This invention relates to the field of calcium carbide transportation equipment for acetylene production, and particularly to an automated calcium carbide transportation equipment for acetylene production. Background Technology

[0002] In the acetylene production process, calcium carbide is a core raw material, and its automated transportation is crucial for production efficiency and safety. Bucket elevators, due to their excellent vertical conveying capacity, are commonly used in calcium carbide transportation systems. However, existing bucket elevators have significant technical defects in calcium carbide transportation. Their bottom design uses a rotating structure with a feeding bucket and a traction chain or belt. To prevent friction and jamming between the bucket and the bottom wall during operation, a rotational gap must be reserved between them. This gap makes it easy for calcium carbide to accumulate during transportation. Long-term accumulation of residual calcium carbide not only wastes raw materials but may also cause safety hazards due to moisture absorption and deterioration. Furthermore, residual accumulation affects the normal operation of equipment, increases manual cleaning costs and labor intensity. Existing transportation devices have not provided an effective solution to this problem and cannot meet the requirements for safe, efficient, and low-loss calcium carbide transportation in acetylene production. Summary of the Invention

A second spring is fixedly provided between one end of the telescopic strip and one side of the inner wall of the arc-shaped cavity. A sliding groove is provided inside the sliding sleeve below the telescopic strip. A positioning shaft is slidably provided on the inner side of the sliding groove. A guide shaft is fixedly provided on the upper side of the positioning shaft. A mating interface is provided on the upper inner wall of the sliding groove corresponding to the position of the guide shaft. A guide groove is provided at the bottom of the telescopic strip corresponding to the position of the guide shaft.

[0008] Preferably, the drive motor rotating shaft is fixedly connected to a set of upper transmission wheels, the square opening corresponds to the material discharge port of the hopper on one side, the arc-shaped strip is located in the middle of the arc-shaped frame, the push block is stuck on the outside of the arc-shaped strip through the opening, and the push block is tilted and rests on the protrusion.

[0009] Preferably, the length of the opening is sufficient to move on the arc-shaped strip, the U-shaped frame and the bottom of the push block are attached to the inner wall of the arc-shaped frame, and the lower side of the spring sheet is elastically pressed against the push block.

[0010] Preferably, the movable sleeve is slidably disposed on the outside of the fixed plate, the upper side of the triangular plate is inclined to correspond to the rotation trajectory of the conveying hopper, and the fixed nail is slidably disposed in the movable opening.

[0011] Preferably, the arc-shaped opening and the arc-shaped groove are positioned correspondingly, the sliding sleeve is slidably disposed inside the arc-shaped opening and the arc-shaped groove, the arc-shaped cavity elastically pushes the positioning shaft to clamp the friction plate with less force than the first spring elastically pushes the triangular plate, so that the first spring pushes the triangular plate to move slowly upward, the telescopic strip partially protrudes from one end of the sliding sleeve, one end of the sliding groove passes through the inside of the sliding sleeve, the sliding groove corresponds to the position of the circular sleeve, and the sliding groove corresponds to the inside of the positioning groove.

[0012] Preferably, one end of the sliding groove is an arc-shaped surface, the guide shaft passes through the interface to the inside of the guide groove, the guide groove is inclined, and the third spring is located at the arc-shaped opening and inside the arc-shaped groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When several sets of hoppers receive and discharge calcium carbide material, some material will fall to the bottom of the arc-shaped frame. The rotating hopper will push the triangular plate. In the initial state, the positioning shaft is inserted into the positioning groove, so it pushes the U-shaped frame, push block, and sliding sleeve to rotate. The sliding sleeve rotates in the arc-shaped opening and arc-shaped groove, while stretching the third spring. When the sliding sleeve slides to one end of the arc-shaped opening, the telescopic bar is squeezed and pushed into the arc-shaped cavity to squeeze the second spring. The guide groove opened on the telescopic bar pushes the guide shaft and positioning shaft to move inward to the inside of the sliding sleeve in the interface and sliding groove. The positioning shaft disengages from the inside of the positioning groove. At this time, the sliding component will unlock the positioning of the triangular plate. When the third spring pulls back the sliding sleeve, the push block returns to the initial position to carry out the next movement.

[0015] 2. When the triangular plate is pushed, it will push the U-shaped frame, push block, and sliding sleeve to rotate clockwise along the arc opening. When the push block leaves the convex strip, it is pushed into the U-shaped frame by the spring. The upper inclined surface of the push block fits against the push block of the U-shaped frame, restricting the rotation of the push block. This makes the push block and the U-shaped frame form a whole plate to scrape up the calcium carbide material falling from the bottom of the arc frame. When the material is pushed by the hopper to the position of the second limit block, the inclined push block pours the calcium carbide material into the hopper, automatically reloading the spilled material. When the push block is pulled back, it moves to the position of the convex strip, which will support the lower side of the push block and elastically squeeze the spring. When receiving or discharging material, the calcium carbide material falling from both sides can slide to the bottom of the arc frame for processing the next shoveling.

[0016] 3. When the positioning shaft unlocks the triangular plate, the rotating hopper pushes the triangular plate downwards, causing the movable sleeve to slide along the fixed plate and three sets of fixed pins. At the same time, it compresses the five sets of first springs. The lowered triangular plate releases the restriction on the rotation of the hopper. Simultaneously, the sliding sleeve and U-shaped frame are pulled back by the third spring. During the pull-back process, the positioning shaft on the front and rear sides presses against the two sets of friction plates. Therefore, when the first spring pushes the triangular plate upwards, the positioning shaft is elastically supported and held in place by the second spring. Since the elastic push of the first spring is slightly greater than that of the second spring, the triangular plate is slowly pushed up during the pull-back process until the positioning shaft is once again locked into the positioning groove for repositioning, thus enabling the next reciprocating operation. This avoids residue buildup at the bottom of the arc frame, which would affect the normal operation of subsequent equipment and increase manual cleaning costs. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship as a relative relationship of orientation or position, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0031] Please see Figures 1-11An embodiment of the present invention provides an automated transport device for calcium carbide used in acetylene production, comprising a bucket elevator 1, a feed hopper 2 fixedly mounted at one lower end of the bucket elevator 1, two sets of drive wheels 3 rotatably mounted inside the bucket elevator 1, a conveyor belt 4 sleeved on the outer side of the two sets of drive wheels 3, and several sets of conveying hoppers 5 evenly fixedly mounted on the outer side of the conveyor belt 4, a drive motor 6 fixedly mounted on the upper side of the bucket elevator 1, and a pushing assembly 7 disposed inside the lower side of the bucket elevator 1. A sliding assembly 8 is disposed on the pushing assembly 7, and the pushing assembly 7 includes an arc-shaped frame 71 fixedly mounted inside the lower side of the bucket elevator 1. 1. Square openings 72 are provided on both sides. An arc-shaped strip 73 is fixedly installed inside the lower side of the arc-shaped frame 71. One side of the arc-shaped strip 73 is provided with a protruding strip 74. A first limiting block 75 is fixedly installed at one end of the arc-shaped strip 73, and a second limiting block 76 is fixedly installed at the other end of the arc-shaped strip 73. A push block 77 is provided on the outer side of the protruding strip 74. A connecting shaft 78 is fixedly installed inside the upper side of the push block 77. An opening 79 is provided in the middle position on the lower side of the push block 77. A U-shaped frame 710 is sleeved on the outer side of the connecting shaft 78. An inclined surface 711 is provided on the upper inner wall of the U-shaped frame 710 and the upper end of the push block 77. A spring piece 712 is fixedly installed at one end of the upper side of the U-shaped frame 710.

[0032] The drive motor 6 rotating shaft is fixedly connected to a set of transmission wheels 3 on the upper side. The square opening 72 corresponds to the material discharge port of the hopper 5 on one side. The arc-shaped strip 73 is located in the middle of the arc-shaped frame 71. The push block 77 is stuck on the outside of the arc-shaped strip 73 through the opening 79. The push block 77 is tilted and rests on the protruding strip 74. The length of the opening 79 is sufficient to move on the arc-shaped strip 73. The U-shaped frame 710 and the bottom of the push block 77 are attached to the inner wall of the arc-shaped frame 71. The lower side of the spring piece 712 is elastically pressed on the push block 77.

[0033] Using the existing bucket elevator technology, the drive motor 6 drives the upper transmission wheel 3 to rotate, which in turn drives the lower transmission wheel 3 and the conveyor belt 4 to rotate several sets of conveying buckets 5, transporting the calcium carbide material entering from the feed bucket 2 upwards. When the triangular plate 716 is pushed, the triangular plate 716 pushes the U-shaped frame 710, push block 77, and sliding sleeve 84 to rotate clockwise along the arc-shaped opening 81. When the push block 77 leaves the protrusion 74, the push block 77 is pushed into the U-shaped frame 710 by the spring piece 712. The upper inclined surface 711 of the push block 77 is in contact with the push block 77 of the U-shaped frame 710. When the push block 77 is rotated, it restricts the rotation of the push block 77, so that the push block 77 and the U-shaped frame 710 form a whole plate. The calcium carbide material falling from the bottom of the arc frame 71 is scraped up and pushed by the hopper 5 to the position of the second limit block 76. When it rotates, the push block 77, which is in an inclined state during the movement, pours the calcium carbide material into the hopper 5, and automatically reloads the spilled material. When the push block 77 is pulled back, it moves to the position of the protrusion 74, which will support the lower side of the push block 77 and elastically squeeze the spring 712. When receiving or discharging material, the calcium carbide material falling from both sides can slide to the bottom of the arc frame 71 for the next scraping.

[0034] A fixing plate 713 is fixedly installed at the upper end of the U-shaped frame 710. A movable sleeve 714 is movably installed on the upper side of the fixing plate 713. Five sets of first springs 715 are fixedly installed between the upper end of the fixing plate 713 and the upper inner wall of the movable sleeve 714. A triangular plate 716 is fixedly installed at one end of the movable sleeve 714. Three sets of fixing nails 717 are fixedly installed at one end of the fixing plate 713 inside the triangular plate 716. Movable openings 718 are opened at one end of the movable sleeve 714 corresponding to the positions of the three sets of fixing nails 717. Circular sleeves 719 are fixedly installed at the front and rear ends of the triangular plate 716 near the lower side. Positioning grooves 720 are opened on the inner side of both sets of circular sleeves 719. Friction plates 721 are fixedly installed on the upper side of the circular sleeves 719.

[0035] The movable sleeve 714 is slidably disposed on the outside of the fixed plate 713, the upper side of the triangular plate 716 is inclined to correspond to the rotation trajectory of the conveying hopper 5, and the fixed nail 717 is slidably disposed in the movable opening 718.

[0036] When the positioning shaft 89 unlocks the triangular plate 716, the rotating hopper 5 pushes the triangular plate 716 downward, causing the movable sleeve 714 to slide along the fixed plate 713 and the three sets of fixed nails 717. At the same time, it squeezes the five sets of first springs 715. After the triangular plate 716 moves down, it releases the restriction on the rotation of the hopper 5. Meanwhile, the sliding sleeve 84 and the U-shaped frame 710 are pulled back by the third spring 813. During the pull-back process, the positioning shaft 89 on the front and rear sides presses against the two sets of friction plates 721. Therefore, when the first spring 715 pushes the triangular plate 716 upward, the positioning shaft 89 is elastically supported and held in place by the second spring 87. Since the elastic push of the first spring 715 is slightly greater than that of the second spring 87, the triangular plate 716 is slowly pushed up during the pull-back process until the positioning shaft 89 is once again locked into the positioning groove 720 for repositioning, realizing the next reciprocating operation. This avoids residue accumulation at the bottom of the arc frame 71, which would affect the normal operation of subsequent equipment and increase manual cleaning costs.

[0037] The sliding component 8 includes two sets of arc-shaped openings 81 on the inner walls of the front and rear sides of the arc-shaped frame 71. Arc-shaped sleeves 82 are fixedly installed at the front and rear ends of the arc-shaped frame 71 corresponding to the positions of the arc-shaped openings 81. Arc-shaped grooves 83 are opened on the inner sides of the two sets of arc-shaped sleeves 82. Sliding sleeves 84 are fixedly installed at the front and rear ends of the fixing plate 713. Arc-shaped cavities 85 are opened on the inner sides of the sliding sleeves 84. Telescopic strips 86 are slidably installed on the inner sides of the arc-shaped cavities 85. A second spring is fixedly installed between one end of the telescopic strip 86 and one side of the inner wall of the arc-shaped cavity 85. Spring 87, sliding sleeve 84 has a sliding groove 88 located on the lower side of telescopic bar 86. A positioning shaft 89 is slidably arranged on the inner side of sliding groove 88. A guide shaft 810 is fixedly arranged on the upper side of positioning shaft 89. A mating interface 811 is opened on the upper inner wall of sliding groove 88 corresponding to the position of guide shaft 810. A guide groove 812 is opened on the bottom of telescopic bar 86 corresponding to the position of guide shaft 810. A third spring 813 is fixedly arranged between one end of sliding sleeve 84 and the inner wall of one side of arc-shaped opening 81 and arc-shaped groove 83.

[0038] The arc-shaped opening 81 and the arc-shaped groove 83 are positioned correspondingly. The sliding sleeve 84 is slidably disposed inside the arc-shaped opening 81 and the arc-shaped groove 83. The arc-shaped cavity 85 elastically pushes the positioning shaft 89 to clamp the friction plate 721 with less force than the first spring 715 elastically pushes the triangular plate 716, so that the first spring 715 pushes the triangular plate 716 to move slowly upward. The telescopic strip 86 protrudes partially from one end of the sliding sleeve 84. One end of the sliding groove 88 passes through the interior of the sliding sleeve 84. The sliding groove 88 corresponds to the position of the circular sleeve 719. The sliding groove 88 corresponds to the interior of the positioning groove 720. One end of the sliding groove 88 is an arc-shaped surface. The guide shaft 810 passes through the interface 811 to the interior of the guide groove 812. The guide groove 812 is inclined. The third spring 813 is located inside the arc-shaped opening 81 and the arc-shaped groove 83.

[0039] When several sets of conveying hoppers 5 receive and discharge calcium carbide material, some material will spill onto the bottom of the arc-shaped frame 71. The rotating conveying hoppers 5 will push the triangular plate 716. In the initial state, the positioning shaft 89 is inserted into the positioning groove 720, so it pushes the U-shaped frame 710, the push block 77, and the sliding sleeve 84 to rotate. The sliding sleeve 84 rotates in the arc-shaped opening 81 and the arc-shaped groove 83, while stretching the third spring 813. When the sliding sleeve 84 slides to one end of the arc-shaped opening 81, the telescopic bar 86... The second spring 87 is squeezed and pushed into the arc-shaped cavity 85, while the guide groove 812 on the telescopic bar 86 pushes the guide shaft 810 and the positioning shaft 89 to move inward into the sliding sleeve 84 in the interface 811 and the sliding groove 88. The positioning shaft 89 disengages from the inside of the positioning groove 720. At this time, the sliding component 8 will unlock the positioning of the triangular plate 716. When the third spring 813 pulls back the sliding sleeve 84, the push block 77 returns to the initial position to carry out the next movement.

[0040] Working principle: In use, using the existing bucket elevator technology, the drive motor 6 drives the upper transmission wheel 3 to rotate, which in turn drives the lower transmission wheel 3 and the conveyor belt 4 to rotate several sets of conveying buckets 5, transporting the calcium carbide material entering from the feed hopper 2 upwards. When the several sets of conveying buckets 5 receive and discharge the calcium carbide material, some material will fall to the bottom of the arc frame 71. The rotating conveying buckets 5 will push the triangular plate 716. In the initial state, the positioning shaft 89 is inserted into the positioning slot 720, so it pushes the U-shaped frame 710 and the push block. 77. The sliding sleeve 84 rotates within the arc-shaped opening 81 and arc-shaped groove 83, simultaneously stretching the third spring 813. When the sliding sleeve 84 slides to one end of the arc-shaped opening 81, the telescopic bar 86 is compressed and pushed into the arc-shaped cavity 85, compressing the second spring 87. Meanwhile, the guide groove 812 on the telescopic bar 86 pushes the guide shaft 810 and positioning shaft 89 to move inwards within the interface 811 and sliding groove 88, disengaging the positioning shaft 89 from the positioning groove 720. At this point, the sliding assembly 8 unlocks the triangular plate 716. Positioning is achieved when the third spring 813 pulls back the sliding sleeve 84, causing the push block 77 to return to its initial position for the next movement. Additionally, when the triangular plate 716 is pushed, it causes the U-shaped frame 710, push block 77, and sliding sleeve 84 to rotate clockwise along the arc-shaped opening 81. As push block 77 leaves the protrusion 74, it is pushed into the U-shaped frame 710 by the spring plate 712. The upper inclined surface 711 of push block 77 fits against the push block 77 of the U-shaped frame 710, restricting its rotation and allowing it to move freely. When the calcium carbide material falling from the bottom of the arc frame 71 is scraped up by the U-shaped frame 710 and pushed by the hopper 5 to the position of the second limit block 76, the tilted push block 77 pours the calcium carbide material into the hopper 5, automatically reloading the spilled material. When the push block 77 is pulled back and moves to the position of the protrusion 74, it will support the lower side of the push block 77 and elastically squeeze the spring 712. When receiving or discharging material, the calcium carbide material falling from both sides can slide to the bottom of the arc frame 71 for the next shoveling.When the positioning shaft 89 unlocks the triangular plate 716, the rotating hopper 5 pushes the triangular plate 716 downwards, causing the movable sleeve 714 to slide along the fixed plate 713 and the three sets of fixing pins 717. Simultaneously, this compresses the five sets of first springs 715. The lowered triangular plate 716 then releases its restriction on the rotation of the hopper 5. At the same time, the sliding sleeve 84 and the U-shaped frame 710 are pulled back by the third spring 813. During this pull-back process, the positioning shaft 89 on the front and rear sides presses against the two sets of friction plates 721. Therefore, when the first spring 715 pushes the triangular plate 716 upwards, the positioning shaft 89 is elastically supported and held in place by the second spring 87. Because the elastic push of the first spring 715 is slightly greater than that of the second spring 87, the triangular plate 716 is slowly pushed up during the pull-back process until the positioning shaft 89 re-engages in the positioning groove 720 for repositioning, enabling the next reciprocating operation. This prevents residue buildup at the bottom of the arc frame 71, which would affect the normal operation of subsequent equipment and increase manual cleaning costs.
