Description

Technical Field

[0001] This application relates to the field of logistics and warehousing, and specifically proposes an automatic tipping device and auxiliary fixing method for tipping over cage carts or bins to dump goods from the top. Background Technology

[0002] Currently, various automated transfer equipment is commonly used in the sorting areas of the e-commerce and express delivery industries to assist on-site personnel in handling large volumes of goods and inbound / outbound operations. Containers used in logistics transit hubs include mixed-pack cage carts or palletized bins. To improve centralized transfer efficiency, specialized equipment is provided for tipping over cage carts or large bins.

[0003] Existing containerized systems commonly employ top-opening unloading methods for convenient combination of cage carts and containers. A previously published domestic patent application, application number 202510641444.1, entitled "Top-Opening Automatic Cargo Tilting Device and Method," combines containers, loading / unloading, and conveying devices within the containerized system to effectively empty all cargo at once during centralized transportation and unloading. The subsequently unloaded mixed cargo is then sorted sequentially on a conveyor line. The device includes a tilting host assembly for inserting containers and tilting them to batch unload cargo; a conveying assembly connected to one side of the tilting host assembly to receive and continuously output the unloaded cargo; containers carrying batches of cargo are fed into the tilting host assembly, and under the drive of a tilting drive device, the containers are tilted towards the conveying assembly. During this process, cargo is successively poured from the containers onto the conveying assembly.

[0004] The existing technology has obvious shortcomings and disadvantages: on the one hand, the combined drive mechanism of large and small sprockets has the disadvantages of short driving arm and poor stability, and the maximum load of the tilting is relatively limited, making it unsuitable for tilting operations of heavy cage cars; on the other hand, the bottom of its tilting main unit adopts a powered external blocking structure such as an electric push rod, which has low safety performance and is prone to failure of one or both sides of the blocking at the same time; in addition, there is no docking device between the tilting main unit and the conveying unit, and the built-in sliding groove assembly allows the tilting main unit to be docked with various conveying equipment at will.

[0005] In view of the above, this patent application is hereby filed. Summary of the Invention

[0006] The automatic tipping device and auxiliary fixing method described in this application are designed to solve the problems existing in the prior art by adopting a transmission form of sprocket drive for incomplete chain rings, in order to significantly improve the stability of the cage car or hopper during the tipping process, effectively solve the problem of large cargo drop height caused by the sprocket and chain drive method in the prior art, and achieve the design purpose of increasing the overall tipping height and the maximum tipping load.

[0007] Therefore, the automatic tipping device described in this application includes a protective net assembly, inside which a support frame assembly and a tilting frame assembly are rotatably connected. The tilting frame assembly is used to insert a container loaded with goods. Under the drive of the tilting drive device, the tilting frame assembly tilts vertically around the rotatable connection with the support frame assembly to tip a batch of goods onto the conveying assembly. The tilting frame assembly includes a main frame with openings on one side and top. A set of incomplete chain rings is fixedly connected to both sides of the main frame. The outer edge of the incomplete chain ring is an arc with an arc between 90° and 180° on the same circle. One end of the chain group is fixedly connected to the same side of the outer edge of the incomplete chain ring by a pin, and the other end is movably connected to the outer edge of the incomplete chain ring by an adjusting screw. Manually rotating the locking nut at the end of the adjusting screw can adjust the tension of the chain group on the outer edge surface of the incomplete chain ring. A set of seated bearings is provided on the side of each set of incomplete chain rings, and the seated bearings are sleeved on the main shaft.

[0008] Furthermore, a top blocking assembly is provided at the junction of the top opening and the side opening of the main frame. This assembly includes two sets of electric push rods located on both sides of the main frame. The bottom of the push rods is mounted on the main frame via an electric cylinder tailstock, and the top of the push rods is fixed to the top pressing bracket via an electric cylinder fixing seat. The top pressing bracket is composed of a series of pressure rods of different lengths connected laterally. A series of guide wheels are provided on both sides of the top pressing bracket and are slidably nested in guide grooves on the main frame.

[0009] Furthermore, an array of mirror-reflective photoelectric sensors are arranged horizontally on the side of the top pressure bracket, near the pressure rod.

[0010] Furthermore, a bottom locking assembly for blocking and laterally positioning the container is connected to one or both sides of the bottom of the main frame. The bottom locking assembly includes a fixed base fixedly connected to the main frame, a bracket set on one side of the fixed base, and a gas spring, a first joint, and a third joint respectively hinged to the bracket by an array of pins. The front end of the gas spring is hinged to the third joint by a set of pins, and the front ends of the first joint and the third joint are respectively hinged to the second joint by a set of pins. A vertically erected collision rod is fixedly connected to the side of the first joint or the third joint, and a columnar collision sleeve is connected to the top of the collision rod.

[0011] Furthermore, at least one set of anti-collision blocks is provided at the bottom of the main frame, opposite to the side opening.

[0012] Furthermore, the support frame assembly is disposed between the flipping frame assembly and the conveying assembly, including a frame, a set of main shafts horizontally mounted on the top via bearings installed on both sides, and a slide chute assembly inclinedly disposed at the front of the frame.

[0013] Furthermore, the protective net assembly includes a left frame and a right frame that are connected and fixed to each other by connecting cross braces. Two sets of motor reducer assemblies are symmetrically arranged on the sides of the left and right frames. The output end of the motor reducer assembly is fitted with a sprocket, which meshes with a chain group on the outer edge of each incomplete chain ring. The flipping drive device includes at least one set of incomplete chain rings arranged on the side of the main frame and at least one set of motor reducer assemblies arranged on the protective net assembly.

[0014] Furthermore, two sets of irregularly shaped collision components are symmetrically arranged on the inner sides of the left and right frames. Each set of irregularly shaped collision components has a folded plate bent towards the operating direction. In the initial state before the container is placed into the flipping frame assembly, the collision rod and / or collision sleeve are laterally pressed against the inner side of the folded plate.

[0015] Based on the above-mentioned automatic tipping device, this application also proposes an automatic tipping auxiliary fixing method: A container carrying a batch of goods is fed into the tilting frame assembly. The top blocking assembly presses down on the goods on top of the container vertically, and the bottom locking assembly extends from one or both sides to the bottom of the container to lock and limit it with the tilting frame assembly. Driven by the tilting drive device, the container is tilted to one side of the conveying assembly. During the tilting process, the container remains relatively stationary with respect to the tilting frame assembly. The goods slide down from the container through the chute assembly to the conveying assembly below. The goods are then transported forward and sorted on the conveying assembly.

[0016] Furthermore, in the initial state before the container is placed in the main frame, the entire flip frame assembly is horizontally located at the bottom of the protective net assembly and remains stationary. At this time, the collision rod and / or collision sleeve are laterally pressed against the inner side of the folding plate. Under the action of the external force of the flip frame assembly's own weight, the gas spring is compressed and drives the third joint to retract backward, and the second joint retracts to the outside of the flip frame assembly. When the container is pushed into the main frame, the second joint still does not contact the bottom of the container; after the equipment is started and the tilting frame assembly achieves tilting operation, as the tilting angle of the main frame increases, the bottom locking assembly moves upward and forward along with the main frame; after the collision rod and / or collision sleeve disengage from the folding plate, the gas spring is in a state of no external force, and under its elastic restoring force, the second joint is extended forward and inserted into the bottom of the empty container; the second joints of the two sets of bottom locking assemblies jointly block and limit the container from both sides, ensuring that the container and the tilting frame assembly remain relatively stationary and tilt synchronously; during this period, the goods are poured out of the container one after another until the tilting frame assembly tilts to the highest point.

[0017] In summary, the automatic tipping device and auxiliary fixing method described above have the following advantages and beneficial effects: 1. This application adopts a sprocket-driven transmission form with a non-complete chain ring, which effectively reduces the drop height of goods and the overall tilting height. The dual-sided servo motor drive significantly improves the maximum tilting load capacity of the whole machine, making it suitable for tilting operations of cage cars or pallet-type material boxes with heavy loads.

[0018] 2. This application uses an elastic telescopic device that allows the four-bar linkage to contact the external collision point during the flipping process, which enables the bottom pallet to be blocked without external power. It is not only simple in structure but also adaptable to the bottom structure of various pallets or cage cars, with high safety and more effectively maintains the relative stability between the cage car or bin and the flipping frame assembly during the flipping process.

[0019] 3. This application adopts a chute mechanism with intermediate docking, which can flexibly dock with various conveying components. While optimizing the tilt angle, it can effectively reduce the risk of goods being stuck on the slide plate, and make reasonable use of the space layout on one side of the flip frame component and the bottom of the chain ring.

Figure 9 D indicates that the cage car has been tilted to its maximum angle; Detailed Implementation

[0021] Example 1, as Figures 1 to 9As shown, the automatic tipping device includes a protective net assembly 3. Inside the protective net assembly 3, a support frame assembly 1 and a tilting frame assembly 2 are rotatably connected. The tilting frame assembly 2 is used to place a container 4 loaded with goods. Driven by the tilting drive device, the tilting frame assembly 2 tilts vertically around the rotatable connection with the support frame assembly 1 to tip a batch of goods onto a conveying assembly (not shown in the figure). On the conveying assembly, the goods are separated and sorted. The support frame assembly 1 is located between the tilting frame assembly 2 and the conveying assembly.

[0022] Specifically, the support frame assembly 1 serves to support the overall tilting frame assembly 2. It includes a frame 1.1, a set of main shafts 1.3 horizontally mounted on the top of 1.1 via bearing seats 1.2 installed on both sides, and a chute assembly 1.4 inclinedly arranged at the front of the frame 1.1. Through the transition of the chute assembly 1.4, the goods poured out from the container 4 fall onto the conveying assembly one after another. The flip frame assembly 2 includes a main frame 2.1 with openings on one side and top. A set of incomplete chain loops 2.3 are fixedly connected to both sides of the main frame 2.1. The outer edge of the incomplete chain loops 2.3 is an arc with an arc between 90° and 180° on the same circle. One end of the chain assembly 2.5 is fixed to the same side of the outer edge of the incomplete chain loop 2.3 by a pin, and the other end is movably connected to the outer edge of the incomplete chain loop 2.3 by an adjusting screw 2.4. The tension of the chain assembly 2.5 on the outer edge surface of the incomplete chain loop 2.3 can be adjusted by manually rotating the adjusting screw 2.4. Each set of incomplete chain rings 2.3 has a set of seated bearings 2.2 on its inner side. The seated bearings 2.2 are sleeved on the main shaft 1.3, thereby realizing the rotational support and connection between the support frame assembly 1 and the flipping frame assembly 2. The main shaft 1.3 passes through both ends of the incomplete chain rings 2.3, and can drive the main frame 2.1 to flip synchronously through the two sets of incomplete chain rings 2.3.

[0023] At least one set of anti-collision blocks 2.6 are provided at the bottom of the main frame 2.1 opposite to the side opening, so as to effectively avoid violent collision between the overturning frame assembly 2 and the support frame assembly 1 during the overturning and tipping of goods, so as to play a buffering role; A top blocking assembly 2.7 is provided at the junction of the top opening and the side opening of the main frame 2.1. The top blocking assembly 2.7 is used to prevent the container 4 and the goods from being spilled out together when tilted. It includes two sets of electric push rods 2.7.3, which are set on both sides of the main frame 2.1. Their bottoms are installed on the main frame 2.1 through electric cylinder tail seats 2.7.4, and their tops are fixed to the top pressure brackets 2.7.1 through electric cylinder fixing seats 2.7.6. The top pressure brackets 2.7.1 are composed of a number of pressure rollers of different lengths connected laterally. They can both position containers 4 of different widths and prevent the goods from slipping. On both sides of the top pressing support 2.7.1, there are arrays of guide wheels 2.7.2 that slide and nest in guide grooves (not shown in the figure) on the main frame 2.1. The guide wheels 2.7.2 are arranged in pairs and symmetrically to guide the electric push rod 2.7.3 during the lifting and lowering process of the top pressing support 2.7.1. Under the synchronous traction drive of the two sets of electric push rods 2.7.3, the top pressing support 2.7.1 drives the array of pressure rods of different lengths to lift and lower. The pressure rods press down vertically on the container 4 containing a batch of goods (at this time, it has been sent into the main frame 2.1 from the side opening) until it is pressed tightly. This ensures that the container 4 remains stationary relative to the main frame 2.1 during the flipping process, and does not completely block the top opening of the container 4 so as not to affect the goods being poured out from the top opening of the container 4. To improve the control accuracy of the top pressure bracket 2.7.1 pressing down on the goods, an array of mirror-reflective photoelectric sensors 2.7.5 can be horizontally arranged on the side of the top pressure bracket 2.7.1, near the pressure roller. These sensors can detect goods that have accumulated and protruded inside the container 4. Only after the sensors detect the goods and trigger the pressing-in signal can the flipping frame assembly 2 begin its flipping operation. The pressing-in signal is fed back to the PLC, which then sends a stop control signal to the electric push rod 2.7.3, stopping the pressure roller from pressing down on the top of the goods or container 10. Simultaneously, because the array of mirror-reflective photoelectric sensors 2.7.5 is arranged horizontally, it can sense different width values ​​of the container 4 loaded below, thus being applicable to containers of different specifications and detecting whether they are loaded into the main frame 2.1.

[0024] A bottom locking assembly 2.8 for blocking and laterally positioning the container 4 is connected to one or both sides of the bottom of the main frame 2.1. The bottom locking assembly 2.8 includes a fixed base 2.8.5 fixedly connected to the main frame 2.1. A bracket 2.8.6 is provided on one side of the fixed base 2.8.5. A gas spring 2.8.4, a first joint 2.8.1, and a third joint 2.8.3 are respectively hinged to the bracket 2.8.6 by an array of pins 2.8.9. The front end of the gas spring 2.8.4 is hinged to the third joint 2.8.3 by a set of pins 2.8.9. The front ends of the first joint 2.8.1 and the third joint 2.8.3 are respectively hinged to the second joint 2.8.2 by a set of pins 2.8.9. A vertically erected collision rod 2.8.7 is fixed to the side of the first joint 2.8.1 or the third joint 2.8.3. A columnar collision sleeve 2.8.8 is connected to the top of the collision rod 2.8.7.

[0025] With the elastic adjustment of the gas spring 2.8.4, the second joint 2.8.2 can extend and retract under the combined action of the first joint 2.8.1 and the third joint 2.8.3. It can extend along the side to the bottom of the cage or pallet to implement blocking positioning, ensuring that the container 4 and the main frame 2.1 remain relatively stationary during the flipping process, preventing the container 4 from tipping over, colliding, or shaking; or, the second joint 2.8.2 can retract from the bottom of the cage or pallet, allowing the container 4 to be pushed out of the main frame 2.1 after the goods have been dumped.

[0026] The protective net assembly 3 includes a left frame 3.1 and a right frame 3.4. The left frame 3.1 and the right frame 3.4 are connected and fixed to each other by connecting cross braces 3.2, and the bottom of both are fixed to the ground by expansion bolts 3.10. Two sets of motor reducer assemblies 3.9 are symmetrically arranged on the sides of the left frame 3.1 and the right frame 3.4. The output end of the motor reducer assembly 3.9 is fitted with a sprocket 3.15, which meshes with the chain group 2.5 on the outer edge of each incomplete chain ring 2.3. Under the synchronous drive of the two sets of motor reducer assemblies 3.9, the two sets of sprockets 3.15 and the chain group 2.5 jointly drive the tilting frame assembly 2 carrying the container 4 to tilt. The flipping drive device described in this application includes at least one set of incomplete chain loops 2.3 disposed on the side of the main frame 2.1, and at least one set of motor reducer assemblies 3.9 disposed on the guard net assembly 3. The chain group 2.5 is disposed along the outer edge of the incomplete chain loops 2.3, and the sprocket 3.15 sleeved at the output end of the motor reducer assembly 3.9 is engaged with the chain group 2.5.

[0027] The left frame 3.1 and the right frame 3.4 are respectively equipped with indicator lights 3.3, L-shaped light curtains, spherical mirrors 3.16, and connecting fixing plates 3.13 for fixing the two ends of the main shaft 1.3. This can ensure that the equipment maintains a safe distance from the operator during operation, prevent other items in the loading area from affecting the start of the equipment, and facilitate observation of the internal working conditions from the outside. A protective net 3.5, an operation module 3.6, an anti-collision component 3.7, an electrical control cabinet 3.8, and a large protective net 3.14 are provided on the outside of the left frame 3.1 or the right frame 3.4, so that the above components can be interchanged to facilitate the interchange of the left and right side operation modes; A connector 3.11 for securing the frame 1.1 is provided on the inner side of the left frame 3.1 and the right frame 3.4 to prevent the equipment from tipping over when the goods are tilted. Two sets of irregularly shaped collision members 3.12 are symmetrically arranged on the inner side of the left frame 3.1 and the right frame 3.4. Each set of irregularly shaped collision members 3.12 has a folded plate 3.12.1 bent towards the direction of the conveying assembly. In the initial state where the container 4 is not placed in the flipping frame assembly 2, the collision rod 2.8.7 and / or the collision sleeve 2.8.8 are laterally pressed against the inner side of the folded plate 3.12.1.

[0028] Specifically, in the initial state, container 4 is not placed in the main frame 2.1 of the flipping frame assembly 2. At this time, the collision rod 2.8.7 and / or the collision sleeve 2.8.8 are laterally pressed against the inner side of the folding plate 3.12.1. Under the action of the external force of the self-weight of the flipping frame assembly 2, the gas spring 2.8.4 is compressed, which drives the third joint 2.8.3 to retract backward, thereby retracting the second joint 2.8.2 to the outside of the flipping frame assembly 2, that is, in the position as Figure 8 In the relaxed state shown in A, even if the container 4 is subsequently pushed into the main frame 2.1, the second joint 2.8.2 still does not contact the bottom of the container 4; When the equipment is started and the flipping frame assembly 2 is in operation, as the flipping angle of the main frame 2.1 increases, the bottom locking assembly 2.8 moves upward and forward along with the main frame 2.1. When the collision rod 2.8.7 and / or the collision sleeve 2.8.8 disengage from the folding plate 3.12.1, the gas spring 2.8.4 is in a state without external force. Under the action of elastic restoring force, its second joint 2.8.2 is extended forward and inserted into the bottom of the container 4. The second joints 2.8.2 of the two sets of bottom locking assemblies 2.8 together block and limit the container 4 from both sides. Figure 8 As shown in B, this ensures that the container 4 and the flipping frame assembly 2 remain relatively stationary while being flipped synchronously, preventing the container 4 from shifting or colliding during the flipping process.

[0029] Based on the structural design of the above-mentioned automatic tipping device, this application also proposes the following automatic tipping auxiliary fixing method: A container 4 containing a batch of goods is fed into a tilting frame assembly 2. A top blocking assembly 2.7 presses down vertically on the goods on top of the container 4. A bottom locking assembly 2.8 extends from one or both sides into the bottom of the container 4 to lock and limit it to the tilting frame assembly 2. Driven by the tilting drive device, the container 4 is tilted toward the conveying assembly side; the tilting drive device includes at least one set of incomplete chain loops 2.3 disposed on the side of the main frame 2.1, and at least one set of motor reducer assemblies 3.9 disposed on the guard net assembly 3; the outer edge of the incomplete chain loop 2.3 is an arc with an arc between 90° and 180° on the same circle, the chain assembly 2.5 is disposed along the outer edge of the incomplete chain loop 2.3, and the output end of the motor reducer assembly 3.9 is fitted with a sprocket 3.15, which is meshed with the chain assembly 2.5; During the flipping process, container 4 remains relatively stationary with respect to the flipping frame assembly 2. Goods slide from container 4 through chute assembly 1.4 onto the conveying assembly below, where they are sequentially transported and sorted.

[0030] Furthermore, in the initial state where the container 4 is not placed in the main frame 2.1, the flip frame assembly 2 is horizontally positioned at the bottom of the protective net assembly 3 and remains stationary. At this time, the collision rod 2.8.7 and / or the collision sleeve 2.8.8 are laterally pressed against the inner side of the folding plate 3.12.1. Under the action of the external force of the self-weight of the flip frame assembly 2, the gas spring 2.8.4 is compressed, which drives the third joint 2.8.3 to retract backward, and the second joint 2.8.2 retracts to the outside of the flip frame assembly 2. When container 4 is pushed into main frame 2.1, the second joint 2.8.2 still does not contact the bottom of container 4. After the equipment is started and the tilting frame assembly 2 is tilted, as the tilting angle of main frame 2.1 increases, the bottom locking assembly 2.8 moves upward and forward along with main frame 2.1. After the collision rod 2.8.7 and / or collision sleeve 2.8.8 disengage from the folding plate 3.12.1, the gas spring 2.8.4 is in a state without external force. Under its elastic restoring force, the second joint 2.8.2 is extended forward and inserted into the bottom of container 4. The second joints 2.8.2 of the two sets of bottom locking assemblies 2.8 jointly block and limit container 4 from both sides, ensuring that container 4 and tilting frame assembly 2 remain relatively stationary and tilt synchronously. During this period, goods are poured out of container 4 one after another until tilting frame assembly 2 tilts to the highest vertical position and all goods are poured out.

[0031] like Figure 9 As shown, taking a cage cart as an example for container 4, the automatic dumping method includes the following implementation steps: Step (1) Push the cage into the cage car; like Figure 9 As shown in Figure A, the cage car is pushed into the main frame 2.1, and the diffuse reflection photoelectric component 2.9 detects and provides feedback on whether the cage car has been pushed into place. Step (2) Cargo positioning; like Figure 9 As shown in B, after the indicator light 3.3 lights up to confirm that the position is in place, click the start button. The top pressing bracket 2.7.1 will press down vertically along its lower edge under the action of the electric push rod 2.7.3. After the mirror photoelectric sensor 2.7.5 senses the goods, the top pressing bracket 2.7.1 will stop at the top of the cage and press the goods firmly. Step (3) Tilting and tilting; like Figure 9 As shown in C, two sets of motor reducer assemblies 3.9 are started simultaneously, and the flipping frame assembly 2 is flipped through the sprocket 3.15 and the chain assembly 2.5. In the initial stage of the flipping frame assembly 2 flipping, the bottom locking assembly 2.8 disengages from the irregular collision part 3.12, and each joint extends forward and inward to the bottom of the car to lock it. The tilting frame assembly 2 continues to drive the cage car to tilt. When the tilt exceeds 90°, the goods in the cage car begin to slide down the chute assembly 1.4 onto the conveying assembly. The chute assembly 1.4 is equipped with detection elements such as photoelectric sensors. After detecting the goods, the conveying assembly is automatically started. The goods are conveyed and sorted sequentially on the conveying assembly. Step (4) Clear; The flipping frame assembly 2 continues to flip until it reaches the highest position. When the photoelectric sensor on the chute assembly 1.4 can no longer detect the goods, it means that all the goods inside the cage car have been emptied. The above steps are reversed. The tilting frame assembly 2, carrying the cage car, tilts back to the bottom of the protective net assembly 3. At this time, under the external force of its own weight, the gas spring 2.8.4 is compressed, which drives the third joint 2.8.3 to retract backward, and the second joint 2.8.2 retracts to the outside of the tilting frame assembly 2. The cage car is released and can be taken out. The automatic tilting device is used in this way.

[0032] As described above, the embodiments given in conjunction with the accompanying drawings are merely preferred solutions for achieving the objectives of this invention. Those skilled in the art can draw inspiration from this and directly derive other alternative structures that conform to the design concept of this invention. Other structural features derived therefrom should also fall within the scope of the solutions described in this invention.

Each set of irregularly shaped collision components has a folded plate bent towards the operating direction. In the initial state before the container is placed into the flip frame assembly, the collision rod and / or collision sleeve are laterally pressed against the inner side of the folded plate.

9. An automatic tilting auxiliary fixing method using the automatic tilting device as described in any one of claims 1 to 8, characterized in that: A container carrying a bulk of goods is fed into the tilting frame assembly. The top blocking assembly presses down vertically on the goods on top of the container, and the bottom locking assembly extends from one or both sides to the bottom of the container to lock and limit it to the tilting frame assembly. Driven by the overturning drive device, the container is overturned toward the conveying assembly. During the flipping process, the container remains relatively stationary with respect to the flipping frame assembly. Goods slide from the container through the chute assembly onto the conveyor assembly below, where they are sequentially transported and sorted.

10. The automatic tilting and auxiliary fixing method according to claim 9, characterized in that: In the initial state before the container is placed in the main frame, the entire flip frame assembly is horizontally located at the bottom of the protective net assembly and remains stationary. At this time, the collision rod and / or collision sleeve are laterally pressed against the inside of the folding plate. Under the action of the external force of the flip frame assembly's own weight, the gas spring is compressed and drives the third joint to retract backward, and the second joint retracts to the outside of the flip frame assembly. When the container is pushed into the main frame, the second joint still does not contact the bottom of the container; after the equipment is started and the tilting frame assembly achieves tilting operation, as the tilting angle of the main frame increases, the bottom locking assembly moves upward and forward along with the main frame; after the collision rod and / or collision sleeve disengage from the folding plate, the gas spring is in a state of no external force, and under its elastic restoring force, the second joint is extended forward and inserted into the bottom of the container; the second joints of the two sets of bottom locking assemblies jointly block and limit the container from both sides, ensuring that the container and the tilting frame assembly remain relatively stationary and tilt synchronously; during this period, the goods are poured out of the container one after another until the tilting frame assembly tilts to the highest point.
