Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stackers, and particularly to a stacking device with a bypass structure. Background Technique
[0002] In the traditional wood processing industry, stackers are an indispensable part of the production line, especially when dealing with a large number of wood chips, their importance is particularly prominent. These mechanisms are usually designed to be able to stack the wood chips from the upstream process in an orderly manner for subsequent storage, transportation or further processing.
[0003] However, when a traditional stacker fails due to mechanical wear, electrical faults or improper operation, its processing capacity will drop significantly or even be completely lost. At this time, if wood chips continue to be conveyed into the stacker, it will not only exacerbate the damage of the equipment, but also may cause a large number of wood chips to accumulate in the conveying channel and form a blockage. To avoid this situation, operators often have to take measures to stop the machine for maintenance and wait for the stacking mechanism to return to normal working condition.
[0004] At this time, a large number of wood chips are accumulated in the conveying channel, which requires additional manpower and material resources for cleaning and management, seriously increasing the management cost of the enterprise. Content of the Utility Model
[0005] In view of the above defects, the utility model proposes a stacking device with a bypass structure. The combined design of the material distribution chute and the bypass pipe not only realizes the rapid transfer of wood chips, but also redistributes the wood chips through the equalizing hopper, solving the problem that the stacking device can only stop working when the traditional stacking mechanism fails. The bypass pipe design of this scheme allows the conveying path to be switched to bypass the fault point without stopping the machine, and continue to complete the transportation operation of wood chips, thus significantly reducing the downtime and the resulting economic losses.
[0006] To achieve this purpose, the utility model adopts the following technical solutions:
[0007] A stacking device with a bypass structure includes a central column, a rotary sleeve, a bypass pipe, a material distribution chute and an equalizing hopper. The bottom of the central column is vertically installed on the equalizing hopper. The top of the central column is rotatably sleeved with a rotary sleeve. A material distribution chute is installed on the side wall of the rotary sleeve. The bypass output end of the material distribution chute is communicated with the bypass pipe. The output end of the bypass pipe is communicated with the input end of the equalizing hopper. The bypass pipe is used for vertically conveying wood chips, and the equalizing hopper is used for outwardly conveying wood chips.
[0008] Further, the bypass pipe includes a first bypass sub-pipe and a second bypass sub-pipe. The first bypass sub-pipe is vertically installed on the side wall of the rotary sleeve, and the second bypass sub-pipe is vertically installed on the side wall of the central column. The input end of the first bypass sub-pipe is communicated with the output end of the material distribution chute. The output end of the first bypass sub-pipe is directly above the input end of the second bypass sub-pipe, and the output end of the second bypass sub-pipe is directly above the opening of the equalizing hopper.
[0009] The opening diameter of the output end of the first bypass sub-pipe is smaller than the opening diameter of the input end of the second bypass sub-pipe.
[0010] The opening diameter of the output end of the second bypass sub-pipe is smaller than the opening diameter of the equalizing hopper.
[0011] The output end of the first bypass sub-pipe contracts inward, and the input end of the second bypass sub-pipe expands outward.
[0012] There are two second bypass sub-pipes, and the two second bypass sub-pipes are respectively installed on both sides of the central column.
[0013] The material distribution chute is of a V-shaped structure. The input end of the material distribution chute is communicated with an external feeder, the bypass output end of the material distribution chute is communicated with the first bypass sub-pipe, and the stacking output end of the material distribution chute is communicated with a stacking structure.
[0014] Bypass valves are provided at the bypass output ends of the material distribution chute.
[0015] The equalizing hopper includes a housing, a screw conveyor and a belt conveyor. The housing is provided with an opening. There are two screw conveyors, and the two screw conveyors are located on both sides of the housing. The output end of the second bypass sub-pipe is at the top of the input end of the screw conveyor. The second bypass sub-pipe corresponds to the screw conveyor one by one. The wood chips at the output end of the second bypass sub-pipe fall into the input end of the corresponding screw conveyor through the opening. The input ends of the belt conveyor are respectively connected to the output ends of the two screw conveyors, and the belt conveyor is used for conveying wood chips outwards.
[0016] The input end of the screw conveyor is lower than the output end of the screw conveyor.
[0017] The technical solution of the present utility model may include the following beneficial effects:
[0018] 1. When a failure occurs in the stacking structure on the stacking device and the wood chip stacking work cannot run normally, the wood chips can quickly transfer from the material distribution chute to the bypass pipe and continue to be conveyed vertically to the equalizing hopper, so as to maintain the continuous conveying of the wood chips, avoid production interruption, and greatly enhance the flexibility and reliability of the stacking system.
[0019] 2. The combined design of the material distribution chute and the bypass pipe not only realizes the rapid transfer of wood chips, but also redistributes the wood chips through the equalizing hopper, solving the problem that when the traditional stacking mechanism fails, the stacking device can only stop working.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0028] The following will describe a stacking device with a bypass structure according to an embodiment of the present utility model in conjunction with Figures 1 to 3 , a stacking device with a bypass structure according to an embodiment of the present utility model.
[0029] A stacking device with a bypass structure includes a central column 1, a rotary sleeve, a bypass pipe 3, a distributing chute 2, and a balancing hopper 5. The bottom of the central column 1 is vertically installed on the balancing hopper 5. The top of the central column 1 is rotatably sleeved with a rotary sleeve. A distributing chute 2 is installed on the side wall of the rotary sleeve. The bypass output end of the distributing chute 2 is communicated with the bypass pipe 3. The output end of the bypass pipe 3 is communicated with the input end of the balancing hopper 5. The bypass pipe 3 is used for conveying wood chips in the vertical direction, and the balancing hopper 5 is used for conveying wood chips outwards.
[0030] When the traditional stacking device faces a failure of the stacking structure, it often needs to stop for maintenance. This not only prolongs the fault handling time but also may cause a large backlog of wood chips, increasing the management cost. For a stacking device with a bypass structure in this solution, when a failure occurs in the stacking structure on the stacking device and the wood chip stacking work cannot operate normally, the wood chips can quickly transfer from the distributing chute 2 to the bypass pipe 3 and continue to be conveyed vertically to the balancing hopper 5, thereby maintaining the continuous conveyance of the wood chips, avoiding production interruption, and greatly enhancing the flexibility and reliability of the stacking system.
[0031] The combined design of the distributing chute 2 and the bypass pipe 3 not only realizes the rapid transfer of wood chips but also redistributes the wood chips through the balancing hopper 5, solving the problem that the stacking device can only stop working when a failure occurs in the traditional stacking mechanism. The design of the bypass pipe 3 in this solution allows, without stopping the machine, to bypass the fault point by switching the conveying path and continue to complete the transportation operation of the wood chips, thereby significantly reducing the downtime and the resulting economic losses.
[0032] The bypass pipe 3 includes a first bypass sub-pipe 31 and a second bypass sub-pipe 32. The first bypass sub-pipe 31 is vertically installed on the side wall of the rotary sleeve, and the second bypass sub-pipe 32 is vertically installed on the side wall of the central column 1. The input end of the first bypass sub-pipe 31 is communicated with the output end of the material distribution chute 2. The output end of the first bypass sub-pipe 31 is directly above the input end of the second bypass sub-pipe 32, and the output end of the second bypass sub-pipe 32 is directly above the opening of the equalizing hopper 5.
[0033] It should be noted that the first bypass sub-pipe 31 is installed on the rotary sleeve, and the input end of the first bypass sub-pipe 31 is communicated with the material distribution chute 2, ensuring that the wood chips can be conveyed into the first bypass sub-pipe 31 under the guidance of the material distribution chute 2. Since the output end of the first bypass sub-pipe 31 is directly above the input end of the second bypass sub-pipe 32, the wood chips at the end of the first bypass sub-pipe 31 naturally fall under the action of gravity and enter the second bypass sub-pipe 32, which not only ensures that the wood chips fall into the equalizing hopper 5 under the action of the bypass pipe 3, but also effectively reduces the problems of breakage or uneven dispersion of the wood chips caused by possible collisions and frictions during the conveying process.
[0034] The opening diameter of the output end of the first bypass sub-pipe 31 is smaller than the opening diameter of the input end of the second bypass sub-pipe 32;
[0035] The opening diameter of the output end of the second bypass sub-pipe 32 is smaller than the opening diameter of the equalizing hopper 5.
[0036] Among them, the smaller opening diameter of the output end of the first bypass sub-pipe 31 helps to slow down the falling speed of the wood chips, make the wood chips disperse more evenly under the action of gravity and enter the second bypass sub-pipe 32, effectively reducing the risk of accumulation and blockage of the wood chips during the falling process, and ensuring the smooth flow of the wood chips in the bypass pipe 3.
[0037] Moreover, the opening diameter of the input end of the second bypass sub-pipe 32 is larger than the output end of the first bypass sub-pipe 31, enabling the second bypass sub-pipe 32 to more effectively receive the wood chips from above and form a certain buffer space inside, effectively reducing the problem of uneven distribution caused by changes in the speed and flow rate of the wood chips.
[0038] Subsequently, when the wood chips are output from the second bypass sub-pipe 32, its smaller opening diameter relative to the opening diameter of the equalizing hopper 5 can also ensure that the wood chips enter the equalizing hopper 5 in a more uniform and concentrated manner, improving the uniformity of the wood chip distribution.
[0039] The output end of the first bypass sub-pipe 31 contracts inward, and the input end of the second bypass sub-pipe 32 expands outward.
[0040] The inwardly contracting design at the output end of the first bypass sub-tube 31, like a funnel or a guiding port, can effectively direct and concentrate the wood chips falling from the material distribution chute 2 in a smaller area. This guiding property not only reduces the scattering of the wood chips during the falling process but also ensures that the wood chips can accurately and quickly enter the second bypass sub-tube 32, improving the accuracy and efficiency of the wood chip transportation.
[0041] The outwardly expanding design at the input end of the second bypass sub-tube 32 forms a spacious receiving area. This area acts as a buffer zone, which can slow down the speed and impact force of the wood chips when entering the second bypass sub-tube 32, reducing the collision and friction between the wood chips.
[0042] Since the wood chips have been effectively guided and buffered before entering the second bypass sub-tube 32, the entire system exhibits higher stability during operation. This stability not only reduces the vibration and wear of mechanical components but also reduces noise and energy consumption, improving the overall performance and reliability of the system.
[0043] There are two second bypass sub-tubes 32, and the two second bypass sub-tubes 32 are respectively installed on both sides of the central column 1.
[0044] It is worth noting that a rotary sleeve is provided on the central column 1, and the rotary sleeve is used to drive the stacking structure to rotate, so that the stacking structure can stack materials around the central column 1. Therefore, in this solution, two second bypass sub-tubes 32 are provided on both sides of the central column 1. When the stacking structure fails, the return sleeve only needs to rotate a certain angle to quickly connect the first bypass sub-tube 31 and the second bypass sub-tube 32 on the rotary sleeve, ensuring that the wood chips can smoothly fall into the equalizing hopper 5.
[0045] Moreover, if one of the second bypass sub-tubes 32 fails or becomes blocked, the other channel can still continue to work, ensuring the continuity and stability of the production line. This design improves the reliability and risk resistance of the system, reducing the downtime and production losses caused by single-point failures.
[0046] The material distribution chute 2 is of a V-shaped structure. The input end of the material distribution chute 2 is connected to an external feeder, the bypass output end of the material distribution chute 2 is connected to the first bypass sub-tube 31, and the stacking output end of the material distribution chute 2 is connected to the stacking structure;
[0047] Bypass valves are provided at the bypass output ends of the material distribution chute 2.
[0048] During the production process, if the stacking structure fails or has an abnormal situation, the bypass valve can be opened to guide the wood chips transported by the external feeder to the bypass pipe 3, so that the wood chips can be transported from the balancing hopper 5 at the bottom of the central column 1 to the next workstation, effectively enhancing the stability and reliability of the stacking device and reducing production risks.
[0049] Moreover, the V-shaped structure of the material distribution chute 2 and the setting of the bypass valve can quickly and conveniently close or open the bypass valve for operation without interrupting the operation of the entire production line, effectively reducing downtime and maintenance costs, and improving equipment utilization and economic benefits.
[0050] The balancing hopper 5 includes an outer shell 51, a screw conveyor 52 and a belt conveyor. The outer shell 51 is provided with an opening. Two screw conveyors 52 are provided. The two screw conveyors 52 are located on both sides of the outer shell 51. The output end of the second bypass sub-pipe 32 is located on the top of the input end of the screw conveyor 52. The second bypass sub-pipe 32 corresponds to the screw conveyor 52 one by one. The wood chips at the output end of the second bypass sub-pipe 32 fall into the corresponding input end of the screw conveyor 52 through the opening. The input end of the belt conveyor is respectively connected to the output ends of the two screw conveyors. The belt conveyor is used to transport wood chips outward.
[0051] Two screw conveyors 52 are arranged in the equalizing hopper 5. Each screw conveyor 52 works independently and is respectively located directly below the corresponding second bypass sub-pipe 32, ensuring that the wood chips can quickly and accurately enter the interior of the screw conveyor 52 from the second bypass sub-pipe 32 through the opening. This one-to-one correspondence effectively improves the accuracy and efficiency of wood chip transportation. Subsequently, the screw conveyor 52 smoothly transports the wood chips to the belt conveyor, which completes the final wood chip output, and the whole process is smooth and efficient.
[0052] The input end of the screw conveyor 52 is lower than the output end of the screw conveyor 52. The screw conveyor 52 gradually lifts the wood chips at a lower position to a higher position by rotating the spiral blades inside the screw conveyor 52. This continuous and progressive conveying method ensures the stability and continuity of the wood chips during the conveying process and avoids the scattering and loss of materials caused by direct lifting or throwing.
[0053] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
