Description

Technical Field

[0001] The present invention relates to the technical field of transport equipment, and in particular to an anti-rollover port cargo belt conveyor. Background Art

[0002] Port cargo belt conveyors are the main force in loading and unloading production operations. They can realize the transfer of goods between trains, ships and yards, and are the core equipment in port logistics for efficiently transporting bulk goods such as coal, ore, and grain, or unitized containerized goods such as containers. Their design needs to take into account high load, long-distance transportation, environmental adaptability and safety.

[0003] Among them, when a port cargo belt conveyor transports goods, if the goods are concentrated on one side of the conveyor, the weight on one side of the conveyor will suddenly increase, causing the conveyor to tilt, affecting the stability of the conveyor during transportation, and in severe cases, the conveyor may roll over, resulting in equipment damage. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an anti-rollover port cargo belt conveyor, including a conveyor frame, and a rotating wheel is rotatably connected to the inner wall of the conveyor frame; A conveying mechanism, a frame assembly is fixedly installed at the bottom of the conveying mechanism, and a driving assembly is installed at the bottom of the conveying mechanism. The frame assembly is used for transporting materials; A counterweight mechanism, the counterweight mechanism is installed at the bottom of the conveying mechanism, and the counterweight mechanism is slidably arranged at the bottom of the conveying mechanism, and is used for changing the center of gravity of the conveyor frame when the conveyor frame tilts; and A leveling mechanism, the leveling mechanism is located at the top of the conveying mechanism, and is used for leveling the materials conveyed by the conveying mechanism; The bottom of the conveyor frame is fixedly connected with a hydraulic frame, and sliding frames are fixedly connected to the front and back of the hydraulic frame. Counterweight blocks are slidably connected to the inner walls of the two sliding frames; Among them, materials are conveyed through the conveying mechanism. When the conveyor frame tilts, the center of gravity of the conveyor frame is changed through the counterweight mechanism to keep the conveyor frame stable. Then, through the leveling mechanism, the piled-up materials are leveled, so as to pull back the tilted conveyor frame and keep it in a stable operating state, effectively preventing the conveyor frame from tilting greatly.

[0005] Preferably, the conveying mechanism includes: A frame assembly, the top of the frame assembly is fixedly arranged with the bottom of the conveyor frame, and is used for transporting materials; A driving assembly, the top of the driving assembly is fixedly arranged with the bottom of the conveyor frame, and is used for controlling the lifting of the counterweight block; Among them, materials are conveyed through the frame component. When the conveyor frame is tilted, the counterweight is lifted and lowered through the drive component to change the center of gravity of the conveyor frame.

[0006] Preferably, the counterweight mechanism includes: A starting component, which is slidably arranged on the inner wall of the hydraulic frame through a sliding part and is used to control the startup of the equipment; The sliding part includes two sliding plates slidably connected to the inner wall of the hydraulic frame, and two button boxes are fixedly connected to the top of the hydraulic frame; A tilting component, which is fixedly arranged on the top of the sliding plate through a support component and is used to control the two counterweights to be at different heights; The support component includes sliding rods fixedly connected to the tops of the two sliding plates, and connecting rods are rotatably connected to the tops of the two sliding rods; Among them, when the conveyor frame is tilted, the starting component will contact the button box, start the drive component, control the lifting and lowering of the counterweight, make the counterweights at different heights through the tilting component, change the center of gravity of the conveyor frame, offset the tilting trend, thereby pulling back the tilted conveyor frame and keeping it in a stable operating state, effectively preventing the conveyor frame from having a large tilting amplitude and avoiding the situation of the conveyor frame tipping over.

[0007] Preferably, the leveling mechanism includes: A pushing component, which is fixedly arranged on the top of the conveyor frame through a connecting component and is used to level the conveyed materials; The connecting component includes two second fixed frames arranged on the top of the conveyor frame, and seven spring return rods are fixedly connected to the bottoms of the two second fixed frames; An extrusion component, which is slidably arranged on the inner wall of the second fixed frame through a blocking component and is used to slow down the return speed of the pushing component; The blocking component includes arc-shaped spring blocks slidably connected to the inner walls of the two second fixed frames, and six connecting rods are fixedly connected to the tops of the two arc-shaped spring blocks; Among them, when the tilting component descends, it will drive the pushing component to descend, contact the conveyed materials, push the materials piled up on one side to move, level the materials, and push the materials piled up on the left side of the conveyor frame to the right side of the conveyor frame. Effectively prevent that after pulling back the tilted conveyor frame, the materials are still piled up on one side, resulting in the risk of the conveyor frame tilting again. The extrusion component slows down the return speed of the pushing component, effectively preventing that during the process of the pushing component pushing the materials to move, due to the continuous conveying of materials, a small amount of materials will move to the left side of the pushing component, and when the pushing component returns, it may push the materials that may move to the left side of the pushing component, causing the materials to fall.

[0008] Preferably, the frame component includes a conveyor belt rotatably connected to the outer wall of the rotating wheel; The driving component includes two hydraulic cylinders fixedly connected to the top of the hydraulic frame. The top output ends of the two hydraulic cylinders are fixedly connected with convex rods. The outer walls of the two convex rods are slidably connected to the inner walls of the counterweight blocks. Hydraulic oil is provided inside the hydraulic frame. Among them, materials are conveyed by a conveyor belt. When the materials accumulate and cause the conveyor frame to tilt, the hydraulic cylinders control the lifting of the counterweight blocks to change the center of the conveyor frame and make it stable.

[0009] Preferably, the starting component includes two inclined frames fixedly connected to the top of the hydraulic frame. Blocking balls are placed inside the two inclined frames, and the blocking balls are used to block the upward movement of the sliding plate. Among them, when the conveyor frame tilts to the left, it will drive the hydraulic frame to tilt to the left. The blocking balls inside the inclined frame will roll, separating the blocking balls from the sliding plate and canceling the blocking of the sliding plate. Since there is hydraulic oil inside the hydraulic frame, when the hydraulic frame tilts, the hydraulic oil inside the hydraulic frame will concentrate on the left side, pushing the sliding plate on the left side to rise until the sliding plate contacts the button box on the left side. At this time, the hydraulic cylinder on the right side will start to work for a period of time, and the hydraulic cylinder will retract, driving the convex rod to descend.

[0010] Preferably, the tilting component includes two push plates slidably connected to the top of the hydraulic frame. The side walls of the two push plates are rotatably connected to the inner walls of the two connecting rods. Spring push blocks are slidably connected to the inner walls of the two counterweight blocks. Among them, when the sliding plate rises, it will drive the sliding rod to rise. The sliding rod will push the connecting rod to rotate, pushing the push plate on the right side to move, so that the push plate pushes the spring push block on the right side to extend to the bottom of the convex rod. The convex rod descending will contact the spring push block and push the spring push block to descend, causing the counterweight block on the right side to slide inside the sliding frame. When the counterweight block on the right side descends, it will cause the rotating frame to rotate, making the right side of the rotating frame descend and the left side rise. The rising side will drive the counterweight block on the left side to rise. Since the spring push block located inside the counterweight block on the left side is not pushed out, the counterweight block on the left side can rise smoothly. The rising of the counterweight block on the left side will lower the left center of gravity, and the descending of the counterweight block on the right side will increase the right center of gravity, changing the center of gravity of the conveyor frame, offsetting the tilting trend, thereby pulling back the tilted conveyor frame and making it maintain a stable operating state, effectively preventing the conveyor frame from having a large tilting amplitude and causing the conveyor frame to tip over.

[0011] Preferably, the tilting component further includes a fixed frame one fixedly connected to the bottom of the conveyor frame. The outer wall of the fixed frame one is rotatably connected to a rotating frame, and the inner walls of the rotating frame are slidably connected to the tops of the two counterweight blocks. Among them, when the counterweight block descends, it will drive the rotating frame to rotate, driving the counterweight block on the other side to rise through the rotating frame, changing the center of gravity of the conveyor frame and reducing the tilting trend of the conveyor frame.

[0012] Preferably, the pushing component includes a fixed block fixedly connected to the top of the counterweight block. The outer walls of the fourteen spring return rods are all slidably connected to the inner wall of the conveyor frame. Five push rods are fixedly connected to the top of each of the two fixed blocks. Rotating plates are rotatably connected to the outer walls of the two fixing brackets II. Spiral springs are fixedly connected to the outer walls of the two rotating plates. Among them, when the counterweight block on the right side descends, it will drive the fixed block and the push rod to descend, causing the push rod to descend and contact the left fixing bracket II, pushing the left fixing bracket II and the spring return rod to descend, so that the spring return rod is squeezed and stores the resilience. The descent of the fixing bracket II will make the rotating plate contact the conveyor belt, causing the rotating plate to be squeezed. Since the contact surface between the conveyor belt and the rotating plate is an inclined surface, the rotating plate will rotate counterclockwise, tightening the spiral spring and storing the resilience, pushing the materials piled up on the left side of the conveyor belt to the right side, effectively preventing the materials from still piling up on the left side after the inclined conveyor frame is pulled back, resulting in the risk of the conveyor frame tilting again.

[0013] Preferably, the extrusion component includes six inclined panels fixedly connected to the front and back of the conveyor frame. The side walls of the twelve connecting rods are all slidably connected to the side walls of the twelve connecting rods. Among them, when the rotating plate rotates, it will contact the arc-shaped spring block and squeeze the arc-shaped spring block, causing the arc-shaped spring block to squeeze the rotating plate. When the rotating plate returns to its original position, the squeezing force of the arc-shaped spring block slows down the return speed of the rotating plate, effectively preventing a small amount of materials from moving to the left side of the rotating plate during the process of the rotating plate pushing the materials from left to right due to the continuous conveying of materials by the conveyor belt. When the rotating plate returns to its original position, it may push the materials that have moved to the left side of the rotating plate to separate from the conveyor belt.

[0014] The present invention has the following beneficial effects: (1) When the present invention is in use, when the conveyor frame tilts to the left, through the driving component, the starting component and the prying component, the counterweight block on the left side can rise smoothly. The rise of the left counterweight block will lower the left center of gravity, and the descent of the right counterweight block will increase the right center of gravity, changing the center of gravity of the conveyor frame and offsetting the tilting trend, thereby pulling back the tilted conveyor frame and keeping it in a stable operating state, effectively preventing the conveyor frame from having a large tilting amplitude and causing the conveyor frame to tip over.

[0015] When the counterweight on the right side of the present invention descends, it will drive the fixed block and the push rod to descend, causing the push rod to descend and contact the second fixed frame on the left side, pushing the second fixed frame on the left side and the spring return rod to descend, so that the spring return rod is squeezed and stores the resilience. The descent of the second fixed frame will make the rotating plate contact the conveyor belt, causing the rotating plate to be squeezed. Since the contact surface between the conveyor belt and the rotating plate is an inclined surface, the rotating plate will rotate counterclockwise, tightening the spiral spring and storing the resilience, and pushing the materials piled up on the left side of the conveyor belt to move to the right side, effectively preventing the materials from still piling up on the left side after the inclined conveyor frame is pulled back, resulting in the risk of the conveyor frame tilting again.

[0016] When the second fixed frame of the present invention descends, the application of the extrusion assembly slows down the return speed of the rotating plate, effectively preventing a small amount of materials from moving to the left side of the rotating plate during the process of the rotating plate pushing the materials to move from left to right due to the continuous conveying of materials by the conveyor belt. As shown in the figure, when the rotating plate returns, it may push the materials that have moved to the left side of the rotating plate to separate from the conveyor belt, resulting in the dropping of materials.

[0017] When the transport frame of the present invention is tilted, the blocking ball will roll onto the inclined surface of the inclined surface frame. When the transport frame is horizontal, the blocking ball will move on the inclined surface of the inclined surface frame and move to the center of the inclined surface frame, blocking the rise of the sliding plate. Since the conveyor belt conveys materials, it will cause the transport frame to vibrate, resulting in the vibration of the hydraulic oil in the hydraulic frame. By blocking the rise of the sliding plate with the blocking ball, it effectively prevents the hydraulic oil in the hydraulic frame from vibrating greatly and pushing the sliding plate to rise, causing the sliding plate to contact the button box when the transport frame is horizontal, resulting in the mis-start of the hydraulic cylinder.

Counterweight blocks 222 are slidably connected to the inner walls of the two sliding frames 221; Among them, materials are conveyed through the conveying mechanism 1. When the transport machine frame 111 is tilted, the counterweight mechanism 2 is used to change the center of gravity of the transport machine frame 111, so that the transport machine frame 111 is kept stable. Then, through the leveling mechanism 3, the materials piled up together are leveled, so as to pull back the tilted transport machine frame 111 and keep it in a stable operating state, effectively preventing the transport machine frame 111 from having a large tilting amplitude.

[0023] The conveying mechanism 1 includes: The frame assembly 11, the top of the frame assembly 11 is fixedly arranged with the bottom of the transport machine frame 111 and is used to transport materials; The driving assembly 12, the top of the driving assembly 12 is fixedly arranged with the bottom of the transport machine frame 111 and is used to control the lifting of the counterweight blocks 222; Among them, materials are conveyed through the frame assembly 11. When the transport machine frame 111 is tilted, the driving assembly 12 is used to control the lifting of the counterweight blocks 222 to change the center of gravity of the transport machine frame 111.

[0024] The counterweight mechanism 2 includes: The starting assembly 21 is slidably arranged on the inner wall of the hydraulic frame 121 through a sliding member and is used to control the start of the equipment; The sliding member includes two sliding plates 211 slidably connected to the inner wall of the hydraulic frame 121. Two button boxes 212 are fixedly connected to the top of the hydraulic frame 121; The tilting assembly 22 is fixedly arranged on the top of the sliding plate 211 through a support member and is used to control the two counterweight blocks 222 to be at different heights; The support member includes sliding rods 223 fixedly connected to the tops of the two sliding plates 211. Connecting rods 225 are rotatably connected to the tops of the two sliding rods 223; Among them, when the transport frame 111 tilts, the activation assembly 21 will contact the button box 212, activate the drive assembly 12, control the lifting of the counterweight 222, and make the counterweight 222 one high and one low through the tilting assembly 22, change the center of gravity of the transport frame 111, offset the tilting trend, thereby pulling back the tilted transport frame 111 and keeping it in a stable operating state, effectively preventing the transport frame 111 from having a large tilting amplitude and causing the transport frame 111 to tip over.

[0025] The leveling mechanism 3 includes: The pushing assembly 31, the pushing assembly 31 is fixedly arranged on the top of the transport frame 111 through a connecting piece and is used to level the transported materials; The connecting piece includes two fixing frames two 311 arranged on the top of the transport frame 111, and the bottoms of the two fixing frames two 311 are fixedly connected with seven spring return rods 312; The extrusion assembly 32, the extrusion assembly 32 is slidably arranged on the inner wall of the fixing frame two 311 through a blocking piece and is used to slow down the return speed of the pushing assembly 31; The blocking piece includes arc-shaped spring blocks 321 slidably connected to the inner walls of the two fixing frames two 311, and the tops of the two arc-shaped spring blocks 321 are fixedly connected with six connecting rods 322; Among them, when the tilting assembly 22 descends, it will drive the pushing assembly 31 to descend, contact the transported materials, push the materials piled up on one side to move, level the materials, and push the materials piled up on the left side of the transport frame 111 to the right side of the transport frame 111, effectively preventing the materials from still being piled up on one side after pulling back the tilted transport frame 111, resulting in the risk of the transport frame 111 tilting again. By the extrusion assembly 32, the return speed of the pushing assembly 31 is slowed down, effectively preventing that during the process of the pushing assembly 31 pushing the materials to move, due to the continuous transportation of materials, a small amount of materials will move to the left side of the pushing assembly 31, and when the pushing assembly 31 returns, it may push the materials that have moved to the left side of the pushing assembly 31 to move, causing the materials to fall.

[0026] Embodiment 2, please refer to Figures 7 - 10 , the present invention is an anti-tipping port cargo belt conveyor. On the basis of Example 1, the frame assembly 11 includes a conveyor belt 113 rotatably connected to the outer wall of the rotating wheel 112; The drive assembly 12 includes two hydraulic cylinders 122 fixedly connected to the top of the hydraulic frame 121. The top output ends of the two hydraulic cylinders 122 are fixedly connected with convex rods 123, and the outer walls of the two convex rods 123 are slidably connected to the inner walls of the counterweight 222. Hydraulic oil is arranged on the inner wall of the hydraulic frame 121; Among them, materials are conveyed by the conveyor belt 113. When the materials accumulate and cause the conveyor frame 111 to tilt, the lifting of the counterweight 222 is controlled by the hydraulic cylinder 122 to change the center of the conveyor frame 111 and make it stable.

[0027] The starting component 21 includes two inclined plane frames 213 fixedly connected to the top of the hydraulic frame 121. Blocking balls 214 are placed at the inner walls of the two inclined plane frames 213, and the blocking balls 214 are used to block the upward movement of the sliding plate 211. Among them, when the conveyor frame 111 tilts to the left, it will drive the hydraulic frame 121 to tilt to the left. For example: Figure 2 As shown, the blocking balls 214 in the inclined plane frame 213 will roll, separating the blocking balls 214 from the sliding plate 211 and canceling the blocking of the sliding plate 211. Since there is hydraulic oil in the hydraulic frame 121, when the hydraulic frame 121 tilts, the hydraulic oil in the hydraulic frame 121 will concentrate on the left side, pushing the sliding plate 211 on the left side to rise until the sliding plate 211 contacts the button box 212 on the left side. At this time, the hydraulic cylinder 122 on the right side will start to work for a period of time, and the hydraulic cylinder 122 will retract, driving the convex rod 123 to descend.

[0028] The tilting component 22 includes two push plates 224 slidably connected to the top of the hydraulic frame 121. The side walls of the two push plates 224 are rotatably connected to the inner walls of the two connecting rods 225, and spring push blocks 226 are slidably connected to the inner walls of the two counterweights 222. Among them, when the sliding plate 211 rises, it will drive the sliding rod 223 to rise. The sliding rod 223 will push the connecting rod 225 to rotate, pushing the push plate 224 on the right side to move, so that the push plate 224 pushes the spring push block 226 on the right side to extend to the bottom of the convex rod 123. The descent of the convex rod 123 will contact the spring push block 226, pushing the spring push block 226 to descend, causing the counterweight 222 on the right side to slide in the sliding frame 221. When the counterweight 222 on the right side descends, it will cause the rotating frame 228 to rotate, making the right side of the rotating frame 228 descend and the left side rise. The rising side will drive the counterweight 222 on the left side to rise. Since the spring push block 226 located in the counterweight 222 on the left side is not pushed out, the counterweight 222 on the left side can rise smoothly. The rise of the counterweight 222 on the left side will lower the left center of gravity, and the descent of the counterweight 222 on the right side will increase the right center of gravity, changing the center of gravity of the conveyor frame 111, offsetting the tilting trend, thereby pulling back the tilted conveyor frame 111 and keeping it in a stable operating state, effectively preventing the conveyor frame 111 from having a large tilting amplitude and causing the conveyor frame 111 to tip over.

[0029] The tilting assembly 22 further includes a first fixing bracket 227 fixedly connected to the bottom of the transport frame 111. A rotating bracket 228 is rotatably connected to the outer wall of the first fixing bracket 227, and the inner walls of the rotating bracket 228 are slidably connected to the tops of the two counterweight blocks 222; Among them, when the counterweight block 222 descends, it will drive the rotating bracket 228 to rotate, and drive the counterweight block 222 on the other side to rise through the rotating bracket 228, changing the center of gravity of the transport frame 111 and reducing the tilting tendency of the transport frame 111.

[0030] The pushing assembly 31 includes a fixing block 313 fixedly connected to the top of the counterweight block 222. The outer walls of the fourteen spring return rods 312 are slidably connected to the inner walls of the transport frame 111. Five push rods 314 are fixedly connected to the tops of the two fixing blocks 313; Rotating plates 315 are rotatably connected to the outer walls of the two second fixing brackets 311, and spiral springs 316 are fixedly connected to the outer walls of the two rotating plates 315; Among them, when the right counterweight block 222 descends, it will drive the fixing block 313 and the push rod 314 to descend, so that the push rod 314 descends and contacts the left second fixing bracket 311, pushing the left second fixing bracket 311 and the spring return rod 312 to descend, causing the spring return rod 312 to be squeezed and storing the resilience. The descent of the second fixing bracket 311 will cause the rotating plate 315 to contact the conveyor belt 113, causing the rotating plate 315 to be squeezed. Since the contact surface between the conveyor belt 113 and the rotating plate 315 is an inclined surface, the rotating plate 315 will rotate counterclockwise, causing the spiral spring 316 to contract and storing the resilience, pushing the materials piled up on the left side of the conveyor belt 113 to move to the right side, effectively preventing the materials from still being piled up on the left side after the tilted transport frame 111 is pulled back, resulting in the risk of the transport frame 111 tilting again.

[0031] The pressing assembly 32 includes six inclined panels 323 fixedly connected to the front and back of the transport frame 111. The side walls of the twelve connecting rods 322 are slidably connected to the side walls of the twelve connecting rods 322; Among them, when the rotating plate 315 rotates, it will contact the arc spring block 321 and squeeze the arc spring block 321, causing the arc spring block 321 to squeeze the rotating plate 315. When the rotating plate 315 returns to its original position, through the squeezing force of the arc spring block 321, the return speed of the rotating plate 315 is slowed down, effectively preventing a small amount of materials from moving to the left side of the rotating plate 315 during the process of the rotating plate 315 pushing the materials from left to right due to the continuous conveying of materials by the conveyor belt 113, and when the rotating plate 315 returns to its original position, it may push the materials that have moved to the left side of the rotating plate 315 to separate from the conveyor belt 113.

[0032] The quantity of the above components is not limited, and those skilled in the relevant art can freely set it according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0033] A specific application of this embodiment is as follows: When the transport frame 111 tilts to the left during the use of the present invention, it will drive the hydraulic frame 121 to tilt to the left. For example: Figure 2 As shown, the blocking rolling ball 214 in the inclined surface frame 213 will roll, separating the blocking rolling ball 214 from the sliding plate 211 and canceling the block on the sliding plate 211. Since there is hydraulic oil in the hydraulic frame 121, when the hydraulic frame 121 tilts, the hydraulic oil in the hydraulic frame 121 will concentrate on the left side, pushing the sliding plate 211 on the left side to rise. The sliding plate 211 will drive the sliding rod 223 to rise, and the sliding rod 223 will push the connecting rod 225 to rotate, pushing the push plate 224 on the right side to move, so that the push plate 224 pushes the spring push block 226 on the right side to extend to the bottom of the convex rod 123 until the sliding plate 211 contacts the button box 212 on the left side. At this time, the hydraulic cylinder 122 on the right side will start to work for a period of time, and the hydraulic cylinder 122 will retract, driving the convex rod 123 to descend, so that the convex rod 123 contacts the spring push block 226, pushing the spring push block 226 to descend, causing the counterweight 222 on the right side to slide in the sliding frame 221. When the counterweight 222 on the right side descends, it will cause the rotating frame 228 to rotate, making the right side of the rotating frame 228 descend and the left side rise. The rising side will drive the counterweight 222 on the left side to rise. Since the spring push block 226 located in the counterweight 222 on the left side is not pushed out, the counterweight 222 on the left side can rise smoothly. The rising of the counterweight 222 on the left side will lower the center of gravity on the left side, and the descending of the counterweight 222 on the right side will increase the center of gravity on the right side, changing the center of gravity of the transport frame 111, offsetting the tilting trend, thereby pulling back the tilted transport frame 111 and keeping it in a stable operating state, effectively preventing the transport frame 111 from having a large tilting amplitude and causing the transport frame 111 to tip over. Among them, after the hydraulic cylinder 122 retracts to the in-place position, it will stay here for a period of time and then extend again to push the counterweight 222 to rise. Secondly, when the counterweight 222 on the right side descends, it will drive the fixed block 313 and the push rod 314 to descend, causing the push rod 314 to descend and contact the second fixing frame 311 on the left side, pushing the second fixing frame 311 and the spring return rod 312 on the left side to descend, so that the spring return rod 312 is squeezed and stores the resilience. The descent of the second fixing frame 311 will cause the rotating plate 315 to contact the conveyor belt 113, causing the rotating plate 315 to be squeezed. Since the contact surface between the conveyor belt 113 and the rotating plate 315 is an inclined surface, the rotating plate 315 will rotate counterclockwise, tightening the spiral spring 316 and storing the resilience, and pushing the materials piled up on the left side of the conveyor belt 113 to move to the right side, effectively preventing the materials from still piling up on the left side after the inclined conveyor frame 111 is pulled back, resulting in the risk of the conveyor frame 111 tilting again; Secondly, when the second fixing frame 31 moves down, it will drive the arc spring block 321 and the connecting rod 322 to descend, causing the connecting rod 322 to separate from the inclined panel 323. Since the arc spring block 321 was in a compressed state before, at this time, the resilience of the arc spring block 321 will be released, causing the arc spring block 321 to pop out. As the rotating plate 315 continues to rotate, the protruding position of the rotating plate 315 will squeeze the arc spring block 321, causing the arc spring block 321 to store the resilience and allowing the arc spring block 321 to squeeze the rotating plate 315. When the counterweight 222 rises again, causing the fixed block 313 and the push rod 314 to rise and separate from the second fixing frame 311, at this time, the resilience of the spring return rod 312 will be released, causing the second fixing frame 311 to rise. By squeezing the rotating plate 315 through the arc spring block 321, the friction force on the rotating plate 315 is increased, thereby slowing down the release speed of the resilience of the spiral spring 316, causing the rotating plate 315 to slowly return to its original position until the connecting rod 322 contacts the inclined surface of the inclined panel 323, causing the connecting rod 322 to be squeezed, separating the arc spring block 321 from the rotating plate 315, allowing the resilience of the spiral spring 316 to be released smoothly, and causing the rotating plate 315 to return to its original position. By slowing down the return speed of the rotating plate 315, it effectively prevents a small amount of materials from moving to the left side of the rotating plate 315 during the process of the rotating plate 315 pushing the materials from left to right due to the continuous conveying of materials by the conveyor belt 113, as Figure 10 shown, when the rotating plate 315 returns to its original position, it may push the materials that have moved to the left side of the rotating plate 315 to separate from the conveyor belt 113; Secondly, when the transport frame 111 is tilted, the blocking rolling ball 214 is blocked from rolling onto the inclined surface of the inclined surface frame 213. When the transport frame 111 is horizontal, the blocking rolling ball 214 will move on the inclined surface of the inclined surface frame 213 and move to the center of the inclined surface frame 213, blocking the lifting of the sliding plate 211. Since the conveyor belt 113 conveys materials, it will cause the transport frame 111 to vibrate, resulting in the vibration of the hydraulic oil in the hydraulic frame 121. By blocking the lifting of the sliding plate 211 with the blocking rolling ball 214, it effectively prevents the hydraulic oil in the hydraulic frame 121 from vibrating greatly and pushing the sliding plate 211 to rise, causing the sliding plate 211 to contact the button box 212 when the transport frame 111 is horizontal, resulting in the mis-start of the hydraulic cylinder 122; The above-mentioned leftward tilt of the transport frame 111 only describes one tilt direction of the transport frame 111. Among them, when the transport frame 111 tilts to the right, the sliding plate 211 on the right will rise and contact the button box 212 on the right, starting the hydraulic cylinder 122 on the left.
