Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and more specifically to a pocket-type vertical lifting conveyor. Background Technology

[0002] In the existing technology, belt conveyors are widely used continuous conveying equipment in the industrial field. They mainly include two types: horizontal and inclined. They are mainly composed of a frame, conveyor belt, drive mechanism, etc. Existing technology usually uses inclined conveyor belts for conveying operations in environments with elevation differences. That is, the feeding end of the conveyor belt is placed at a low position and the unloading end is placed at a high position to send the material from the low position to the high position.

[0003] Chinese patent CN220563490U discloses a "large-angle enclosed belt conveyor device," which includes a large-angle sidewall belt conveyor. A lifting platform is provided on one side of the conveyor. The lifting platform includes two parallel guide rails, with a working trolley positioned between them. The working trolley moves along the guide rails. A winch is located at the upper end of each guide rail, and a steel wire rope is wound around the winch's drum. The free end of the steel wire rope is connected to the working trolley. The working trolley is equipped with a fall protection device. Several counter-teeth that cooperate with the fall protection device are provided along the length of the top of each guide rail, with the concave surface of the counter-teeth facing upwards at an angle. This patent facilitates worker maintenance of the conveyor and reduces operational risks compared to ladder-climbing operations.

[0004] However, the existing technology has the following problems: The existing inclined conveyor belts have a limited range of inclination angles. Therefore, as the height of material conveying increases, the length of the belt itself also needs to be increased. As a result, the installation area of ​​inclined conveyor belts is usually large, making them difficult to install and use in situations with limited space. Summary of the Invention

[0005] The purpose of this invention is to provide a pocket-type vertical lifting conveyor to solve the above-mentioned problems, and to overcome the shortcomings of existing inclined conveyor belts, which usually require a large installation area and are difficult to install and use in situations with limited space, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a pocket-type vertical lifting conveyor, comprising a head frame and a tail frame. Two sets of drive rollers are respectively installed on the head frame and tail frame, and a conveyor belt is sleeved on each of the two sets of drive rollers. A discharge hopper is installed on the head frame, and a feeding hopper is installed on the tail frame. The conveyor belt includes two base belts, which are sleeved on the two sets of drive rollers. Multiple mounting crossbars are connected at equal intervals between the two base belts, and a pocket-type hopper is installed between every two adjacent mounting crossbars. The head frame is equipped with a vibration component for striking the pocket-type hopper as it passes over the discharge hopper to promote material drop. The head frame is also equipped with a cleaning component for cleaning the conveyor belt.

[0007] Preferably, the head frame and tail frame are each equipped with a driver for driving two sets of drive rollers to rotate, and one of the drive rollers on the head frame is located above the unloading hopper.

[0008] Preferably, the vibration assembly includes a fixed frame and multiple pry bars. The fixed frame is mounted on the unloading hopper, and the multiple pry bars are rotatably mounted on the fixed frame. One end of each pry bar is connected to a hammer, and the other end of each pry bar is connected to a second sliding shaft. A movable frame is horizontally slidably mounted on the fixed frame. The movable frame has multiple longitudinal slots, and the second sliding shafts on the multiple pry bars are slidably connected to the multiple longitudinal slots respectively. When the movable frame moves horizontally back and forth, it can drive the multiple pry bars to swing back and forth by utilizing the cooperation of the multiple longitudinal slots and the multiple second sliding shafts. The vibration assembly also includes a linkage mechanism for driving the movable frame to move back and forth.

[0009] Preferably, the linkage mechanism includes a ratchet gear, which is installed on the outer wall of the drive roller located above the unloading hopper. The two ends of the movable frame are respectively connected to a first sliding shaft and a spring rod. The first sliding shaft is in sliding contact with the ratchet gear, and the end of the spring rod away from the movable frame is connected to the fixed frame.

[0010] Preferably, the ratchet has multiple ratchet teeth arranged in a circumferential array, and when the ratchet teeth move, they contact the first sliding shaft and drive the first sliding shaft to move toward the ratchet.

[0011] Preferably, the cleaning assembly includes a first brush, a pair of connecting arms are mounted on the mounting bracket, a carriage is slidably connected to the pair of connecting arms, the first brush is mounted on the carriage, and the inner side of the baseband and the outer side of the pocket hopper come into contact with the first brush during movement.

[0012] Preferably, the cleaning assembly includes a second brush, a connecting frame is connected to the carriage, the second brush is mounted on the connecting frame, and the outer side of the base belt and the opening of the pocket hopper come into contact with the second brush during movement.

[0013] Preferably, a third sliding shaft is connected to the slide, a groove plate is connected to the movable frame, a wavy groove is formed on the groove plate, and the third sliding shaft is slidably connected to the wavy groove.

[0014] Preferably, the unloading hopper is provided with a clearing component, which includes a smooth rod installed inside the unloading hopper. A rotating ring is rotatably connected to the outer wall of the smooth rod. Multiple sleeves are connected in a circumferential array on the outer wall of the rotating ring. A clearing rod is movably inserted into the inner wall of each sleeve. The clearing rod is provided with multiple burrs. When the clearing rod passes over the pocket-shaped hopper above it, it can be inserted into the pocket-shaped hopper and use the counter-thrust force of the pocket-shaped hopper to drive the rotating ring and the sleeves above it to rotate.

[0015] Preferably, one end of the unclogging rod located inside the sleeve is connected to a reciprocating rod, and the end of the reciprocating rod away from the unclogging rod is rotatably connected to a sliding rod. A fourth sliding shaft is connected to the sliding rod, and the fourth sliding shaft extends radially through the sleeve to the outside of the sleeve. A groove is provided on the sleeve for the fourth sliding shaft to slide axially along the sleeve. A sliding tongue is provided inside the sleeve, and the sliding tongue is slidably connected to a spiral groove on the surface of the reciprocating rod. A grooved plate is connected to the outer wall of the smooth rod, and a quincunx-shaped sliding groove is provided on the grooved plate. The fourth sliding shaft is slidably connected to the quincunx-shaped sliding groove.

[0016] The beneficial effects are: 1. This pocket-type vertical lifting conveyor, through the setting of the conveyor belt, enables each pocket-type hopper to form an independent storage space. When the material enters the pocket-type hopper, the material uses its own gravity to drive the storage part of the pocket-type hopper to fall, thereby keeping the material inside the pocket-type hopper away from the opening above, preventing the material from spilling, and thus stably lifting the material vertically to a high place. Compared with conventional inclined conveyors, the vertical lifting method of the conveyor belt greatly reduces the footprint and improves the space utilization rate.

[0017] 2. This pocket-type vertical lifting conveyor, through the setting of the vibration component, enables the drive roller on the head frame to drive the ratchet to rotate. The ratchet, in conjunction with the first sliding shaft and the spring rod, drives the movable frame to move horizontally back and forth. The movable frame, through the linkage of the second sliding shaft with multiple pry bars installed on the fixed frame, swings so that each pocket-type hopper can be struck in sequence as it passes under multiple hammers, thereby ensuring that the material inside can fall quickly using vibration.

[0018] 3. This pocket-type vertical lifting conveyor, through the setting of the unblocking components, achieves the technical effect of the unblocking rod using the reverse thrust of the moving pocket hopper to realize the linkage operation of the entire unblocking component. As each unblocking rod enters the inner wall of the pocket hopper, it performs a compound motion of extension, reciprocating rotation to achieve the unblocking action, thereby enabling the unblocking rod to effectively agitate the material in the pocket hopper and promote the falling of the material.

[0026] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0027] Please see Figure 1 - Figure 3 In one embodiment: A pocket-type vertical lifting conveyor includes a head frame 1 and a tail frame 2. Two sets of drive rollers are installed on the head frame 1 and the tail frame 2 respectively. A conveyor belt 3 is sleeved on the two sets of drive rollers. The conveyor belt 3 is used for vertical conveying. Its two ends are respectively connected to the conveyor rollers of the head frame 1 and the tail frame 2. The tail frame 2 is located at the lower loading end, and the head frame 1 is located at the higher unloading end. The conveyor belt 3 is used to transport materials from the lower to the higher position. A discharge hopper 4 is installed on the head frame 1, and a loading hopper 5 is installed on the tail frame 2. The head frame 1 and the tail frame 2 are respectively equipped with a driver for driving the two sets of drive rollers to rotate. One of the drive rollers on the head frame 1 is located above the discharge hopper 4. The driver provides rotational power to the drive rollers on the head frame 1 and the tail frame 2. The drive roller drives the conveyor belt 3 to form a closed-loop vertical circulation. The tail frame 2, which is arranged at a low position, can smoothly guide the material onto the conveyor belt 3 with the loading hopper 5. The head frame 1, which is arranged at a high position, can receive the falling material with the discharge hopper 4, thus stably realizing the vertical lifting of materials with low loading and high unloading.

[0028] Specifically, the conveyor belt 3 includes two base belts 31, which are mounted on two sets of drive rollers. Multiple mounting crossbars 32 are connected at equal intervals between the two base belts 31, and a pocket-type hopper 33 is installed between every two adjacent mounting crossbars 32. The two base belts 31, the multiple mounting crossbars 32, and the multiple pocket-type hoppers 33 form the conveyor belt 3. The two base belts 31 achieve synchronous cyclic movement by the drive rollers, bearing the overall load and traction transmission. The multiple mounting crossbars 32 connect the two base belts 31 together, improving the structural stability of the conveyor belt 3 and providing installation positions for the pocket-type hoppers 33, allowing multiple pocket-type hoppers 33 to be assembled at equal intervals on the two base belts 31. When the two base belts 31 circulate, multiple... The pocket hoppers 33 move synchronously in a circular motion. When the pocket hoppers 33 pass the tailstock 2 at their low position, they receive the material fed from the upper hopper 5. At their high position, they flip with the base belt 31 and unload the material into the discharge hopper 4. The capacity of the pocket hoppers 33 extends inward to the base belt 31, so that each pocket hopper 33 can form an independent storage space. The pocket hoppers 33 have a certain degree of flexibility. When the material enters the pocket hopper 33, the material uses its own gravity to drive the storage part of the pocket hopper 33 to fall, thereby keeping the material inside the pocket hopper 33 and away from the opening above, preventing the material from spilling. This stabilizes and vertically lifts the material to a high position. Compared with conventional inclined conveyors, the vertical lifting method of the conveyor belt 3 greatly reduces the footprint and improves space utilization.

[0029] Please see Figure 1 - Figure 6 In another embodiment: The head frame 1 is equipped with a shocking component 6, which is used to strike the pocket hopper 33 as it passes over the discharge hopper 4 to promote material drop. The shocking component 6 includes a fixed frame 61 and multiple pry bars 66. The fixed frame 61 is mounted on the discharge hopper 4, and the multiple pry bars 66 are rotatably mounted on the fixed frame 61. One end of the pry bar 66 is connected to a hammer 67, and the other end of the pry bar 66 is connected to a second sliding shaft 68. A movable frame 62 is horizontally slidably mounted on the fixed frame 61. The movable frame 62 has multiple longitudinal grooves. The second sliding shafts 68 on the multiple pry bars 66 are slidably connected to the multiple longitudinal grooves respectively. When the movable frame 62 moves horizontally back and forth, it can utilize the multiple longitudinal grooves and the multiple second sliding shafts 68 to achieve the desired effect. The combined action drives multiple pry bars 66 to swing back and forth. The vibration assembly 6 also includes a linkage mechanism for driving the movable frame 62 to move back and forth. The fixed frame 61 is fixed to the unloading hopper 4 by a bracket. The pivot point of the pry bar 66 is located between the second sliding shaft 68 and the hammer 67, forming a lever structure. Therefore, when the movable frame 62 slides horizontally back and forth, the second sliding shaft 68 is pulled by the longitudinal groove limit, which drives the pry bar 66 to swing back and forth around the mounting pivot point. When the pry bar 66 swings, it drives the end hammer 67 to intermittently strike the pocket hopper 33 passing through the unloading area. The vibration shakes the material inside the pocket hopper 33, preventing the material from getting stuck in the pocket hopper 33 and failing to fall in time, thereby reducing the accumulation of material residue.

[0030] Furthermore, the linkage mechanism includes a ratchet 63, which is mounted on the outer wall of the drive roller located above the discharge hopper 4. The two ends of the movable frame 62 are respectively connected to a first sliding shaft 64 and a spring rod 65. The first sliding shaft 64 slides in contact with the ratchet 63, and the end of the spring rod 65 away from the movable frame 62 is connected to the fixed frame 61. Multiple ratchet teeth are arranged in a circumferential array on the ratchet 63. When the ratchet teeth move, they contact the first sliding shaft 64 and drive the first sliding shaft 64 to move closer to the ratchet 63. The ratchet 63 rotates synchronously with the drive roller above the discharge hopper 4, directly utilizing the power of the drive roller without the need for an additional motor drive, resulting in energy saving, environmental protection, and a simplified structure. During rotation, the multiple ratchet teeth sequentially contact the first sliding shaft 64 and push the movable frame 62 closer to the ratchet 63 through the first sliding shaft 64. Each ratchet tooth can be considered as a… With one inclined side and one straight side, the first sliding shaft 64 moves along the inclined side away from the center of the ratchet 63 when sliding along the ratchet. At this time, the movable frame 62 compresses the spring rod 65 to store energy, and the first sliding shaft 64 maintains pressure on the ratchet. When the first sliding shaft 64 passes the inclined side, the elastic force of the spring rod 65 causes the first sliding shaft 64 to rebound instantaneously along the straight side of the ratchet until it contacts the angle between two adjacent ratchet teeth. Therefore, the first sliding shaft 64 and the movable frame 62 move slowly and compress the spring rod 65 when approaching the ratchet 63. After moving to the position, the elastic force of the spring rod 65 is used to quickly rebound away from the ratchet 63. Therefore, after the pry bar 66 drives the hammer 67 to tilt and store energy, it can use the elastic force of the spring rod 65 to quickly strike the pocket hopper 33 below it, thus forming an intermittent striking effect.

[0031] More specifically, the number and spacing of the ratchet teeth of the ratchet 63 are matched with the spacing of the pocket hoppers 33, ensuring that each time a pocket hopper 33 passes under the hammer 67, the hammer 67 can strike the pocket hopper 33 below it once. The multiple hammers 67 are arranged side by side, so that each pocket hopper 33 can be struck in turn as it passes under multiple hammers 67, thereby ensuring that the material inside can fall out quickly by vibration.

[0032] Please see Figure 4 , Figure 7 - Figure 9 In another embodiment: The head frame 1 is equipped with a cleaning component 7 for cleaning the conveyor belt 3. The cleaning component 7 includes a first brush 73. A pair of connecting arms 71 are installed on the fixed frame 61. A slide 72 is slidably connected to the pair of connecting arms 71. The first brush 73 is installed on the slide 72. The inner side of the base belt 31 and the outer side of the pocket hopper 33 come into contact with the first brush 73 during movement. The connecting arms 71 are fixed to the fixed frame 61 to provide sliding guide support for the slide 72. The slide 72 carries the first brush 73, so that the brush is in close contact with the inner side of the base belt 31 and the outer side of the pocket hopper 33. During the circulation of the conveyor belt 3, the first brush 73 continuously brushes off the impurities adhering to the inner side of the base belt 31 and the impurities adhering to the outer wall of the pocket hopper 33, so as to avoid the accumulation of impurities on the conveyor belt 3 and affect its performance, thus extending the service life of the conveyor belt 3.

[0033] It is worth noting that the cleaning component 7 includes a second brush 75, and a connecting frame 74 is connected to the carriage 72. The second brush 75 is mounted on the connecting frame 74. The outer side of the base belt 31 and the opening of the pocket hopper 33 come into contact with the second brush 75 during movement. The connecting frame 74 securely mounts the second brush 75 on the carriage 72, forming a two-way cleaning combination with the first brush 73. The first brush 73 and the second brush 75 surround and clean the inner and outer sides of the conveyor belt 3. The second brush 75 specifically cleans the impurities on the outer side of the base belt 31 and the impurities at the opening of the pocket hopper 33, further improving the cleaning effect.

[0034] It is worth mentioning that a third sliding shaft 76 is connected to the slide 72, and a grooved plate 77 is connected to the movable frame 62. The grooved plate 77 has a wavy groove, and the third sliding shaft 76 is slidably connected to the wavy groove. When the movable frame 62 performs horizontal reciprocating motion, it synchronously drives the grooved plate 77 to move synchronously. When the grooved plate 77 reciprocates, the wavy groove continuously applies a force to the third sliding shaft 76. In this embodiment, the third sliding shaft 76 and the slide 72 can only move back and forth, while the movable frame 62 and the grooved plate 77 move left and right. As the wavy chute moves continuously, the third sliding shaft 76 is guided by the wavy chute to move back and forth, matching the movement trajectory of the wavy chute. This, in turn, causes the slide 72 to move back and forth slightly. The slide 72 then causes the first brush 73 and the second brush 75 to vibrate continuously. This dynamic vibration of the first brush 73 and the second brush 75 enhances the impact force during cleaning and helps to shake off the impurities attached to themselves, ensuring their cleanliness and reducing the frequency of manual cleaning and maintenance.

[0035] Please see Figure 5 , Figure 10 , Figure 11 In another embodiment: The unloading hopper 4 is equipped with a clearing assembly 8, which includes a smooth rod 81 installed inside the unloading hopper 4. A rotating ring 82 is rotatably connected to the outer wall of the smooth rod 81. Multiple sleeves 83 are connected in a circular array on the outer wall of the rotating ring 82. A clearing rod 86 is movably inserted into the inner wall of each sleeve 83. The clearing rod 86 has multiple burrs. When the clearing rod 86 passes over the pocket hopper 33 above it, it can insert into the pocket hopper 33 and use the counter-thrust of the pocket hopper 33 to drive the rotating ring 82 and the sleeves 83 above it to rotate. The smooth rod 81 provides a rotation axis support for the rotating ring 82. The multiple sleeves 83 can revolve around the rotating ring 82. The multiple sleeves 83 are evenly distributed radially. The rotating ring 82, the multiple sleeves 83 above it, and the clearing rod 86 can be regarded as a gear, while the row of pocket hoppers 33 passing above it can be regarded as a... The process of each unblocking rod 86 entering a pocket hopper 33 is considered as the meshing of a gear and a rack. Therefore, when each pocket hopper 33 passes over an unblocking rod 86, the unblocking rod 86 first enters the inner wall of the pocket hopper 33. Then, the inner wall of the pocket hopper 33 applies a force to the unblocking rod 86 during its movement, causing the unblocking rod 86 to drive the rotating ring 82 to rotate continuously on the smooth rod 81 through the sleeve 83. This achieves the technical effect of the unblocking rod 86 using the counter-thrust force of the moving pocket hopper 33 to achieve the linkage operation of the entire unblocking assembly 8. During the process of each unblocking rod 86 entering the inner wall of the pocket hopper 33, the unblocking rod 86 and the burrs on it can directly insert into the material and perform unblocking action, causing the slightly lumped material during the conveying process to break up directly and allowing the material to fall quickly.

[0036] Furthermore, one end of the unblocking rod 86 located inside the sleeve 83 is connected to a reciprocating rod 85, and the end of the reciprocating rod 85 away from the unblocking rod 86 is rotatably connected to a sliding rod 84. A fourth sliding shaft 87 is connected to the sliding rod 84, and the fourth sliding shaft 87 extends radially through the sleeve 83 to the outside of the sleeve 83. The sleeve 83 has a groove for the fourth sliding shaft 87 to slide axially along the sleeve 83. A sliding tongue is provided inside the sleeve 83, and the sliding tongue is slidably connected to the spiral groove on the surface of the reciprocating rod 85. A grooved plate 88 is connected to the outer wall of the smooth rod 81, and a quincunx-shaped sliding groove is provided on the grooved plate 88. The fourth sliding shaft 87 is slidably connected to the quincunx-shaped sliding groove. Taking one of the sleeves 83 as an example, when the rotating ring 82 and the sleeve 83 rotate, the fourth sliding shaft 87 slides along the quincunx-shaped sliding groove trajectory of the grooved plate 88. The fourth sliding shaft 87 and the sliding groove of the sleeve 83 form a limiting mechanism, so that the sliding rod 84 and the fourth sliding shaft 87 can only slide along the quincunx-shaped sliding groove trajectory. The fourth sliding shaft 87 slides axially along the inner wall of the sleeve 83. The plum blossom-shaped groove can be considered as being composed of multiple alternating peaks and troughs. Therefore, when the fourth sliding shaft 87 slides along the peaks and troughs of the plum blossom-shaped groove, it can drive the sliding rod 84 to extend and retract inside the sleeve 83. When the sliding rod 84 extends and retracts, it drives the reciprocating rod 85 to extend and retract synchronously inside the sleeve 83. The reciprocating rod 85 is provided with a spiral groove. The sliding tongue inside the sleeve 83 cooperates with the spiral groove of the reciprocating rod 85 to convert the linear displacement of the reciprocating rod 85 into the rotational power of the reciprocating rod 85. This allows the reciprocating rod 85 to reciprocate while extending and retracting. This allows the reciprocating rod 85 to drive the connecting unblocking rod 86 to perform a combined extension and reciprocating rotation motion during insertion into the pocket hopper 33. This allows the unblocking rod 86 to effectively agitate the material in the pocket hopper 33, further improving the material discharge efficiency.

[0037] When the pocket-type vertical lifting conveyor is in use, the drive units of the head frame 1 and tail frame 2 drive the drive rollers at both ends to rotate, pulling the two base belts 31 of the conveyor belt 3 to perform a closed-loop vertical circulation motion. The base belts 31 are fixed with several pocket-type hoppers 33 by the mounting crossbars 32. The material is loaded into the pocket-type hoppers 33 from the upper hopper 5 above the lower tail frame 2, and then lifted by the conveyor belt 3 to the unloading hopper 4 corresponding to the upper head frame 1 to complete the unloading. During the unloading process, the drive rollers on the head frame 1 drive the ratchet 63 to rotate, which, together with the first sliding shaft 64 and the spring rod 65, drives the movable frame 62 to move horizontally back and forth. The movable frame 62, through the second sliding shaft 68, links multiple pry bars 66 installed on the fixed frame 61 to swing, causing the hammer 67 to intermittently strike the pocket-type hoppers 33 to help shake off residual material. At the same time, the movable frame 62 drives the trough plate 77 to move accordingly, using waves The wave-shaped chute, in conjunction with the third sliding shaft 76, drives the slide frame 72 to slide and vibrate along the connecting arm 71, allowing the first brush 75 on the slide frame 72 and the second brush 75 mounted on the connecting frame 74 to dynamically clean the inner and outer sides of the base belt 31 and the surface of the pocket hopper 33 of residual debris in both directions. Inside the unloading hopper 4, the rotating ring 82 can rotate by utilizing the thrust of the unblocking rod 86 when the pocket hopper 33 is running, causing the unblocking rods 86 on multiple sleeves 83 to alternately insert into the pocket hopper 33 that moves in sequence. At the same time, the fourth sliding shaft 87 slides along the plum blossom-shaped chute of the groove plate 88, linking the sliding rod 84 and the reciprocating rod 85 in conjunction with the sliding tongue inside the sleeve 83, so that the unblocking rod 86 can achieve a compound agitation of extension and rotation, breaking up the clumps of material and scraping off the material adhering to the inner wall, completing the entire process of stable operation of material feeding, vertical lifting, auxiliary unloading, and self-cleaning unblocking.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
