Description

Technical Field

[0001] The present application relates to the technical field of material unloading and transfer equipment, and in particular to an automatically telescopic chute with high stability and its application method. Background Art

[0002] The general goods at bulk cargo ports and terminals are coal, iron ore concentrate, grain, etc. These stored goods are often fine and light in texture. During the process of storage, transfer, loading and unloading, serious dust pollution will occur, especially prominent in windy seasons. In order to reduce this impact and at the same time accurately and dispersedly load the goods into the cabin, a telescopic chute is generally provided on the ship loader. During the loading process, the telescopic chute is extended into the cabin so that the goods directly enter the cabin along the chute, avoiding situations such as dust flying. At the same time, for the rapid transfer of some bulk materials, the chute can also be tilted so that the materials slowly fall into the cabin, avoiding a large impact on the cabin caused by the materials.

[0003] In the related art, the chute is usually used in combination with a head funnel. The bottom of the head funnel is inclined. Therefore, in the actual use process, when the material slides down along the inclined bottom wall of the head funnel, it often impacts directly on the chute obliquely. After multiple impacts, the chute is likely to be damaged and needs to be frequently repaired, so there is room for improvement. Summary of the Invention

[0004] In order to reduce the impact of materials on the chute, the present application provides an automatically telescopic chute with high stability and its application method.

[0005] In the first aspect, an automatically telescopic chute with high stability and its application method provided by the present application adopt the following technical solutions: An automatically telescopic chute with high stability includes a connected head funnel and a first section of chute. The inner bottom wall of the head funnel has an inclined feeding slope. A guiding baffle is arranged inside the head funnel. The guiding baffle includes a sloping baffle, a transition baffle and a vertical baffle connected in sequence. The sloping baffle is parallel to the feeding slope, and the vertical baffle is parallel to the axis of the chute.

[0006] By adopting the above technical solutions, during use, the first section of the chute is placed vertically, and materials are continuously fed from the head funnel. The materials first fall obliquely under the guiding action of the feeding slope, then abut against the sloping baffle, and turn as they move to the transition baffle along the sloping baffle, and finally adjust the falling direction from the vertical baffle, so that the final falling direction of the materials can be adjusted to be close to vertical falling. Compared with the way in the related art where the materials can only directly impact the side wall of the first section of the chute along the feeding slope, the impact and wear of the materials on the first section of the chute or the subsequent chute during the falling process are effectively reduced.

[0007] Preferably, an accumulation material partition layer with an L-shaped cross-section is further arranged inside the first chute. The accumulation material partition layer is of an annular structure. An accumulation material area is formed between the accumulation material partition layer and the inner wall of the first chute. The accumulation material area is in the shape of an annular groove and has an upward opening.

[0008] By adopting the above technical solution, on the one hand, when the material enters the first chute, even if the material collides with the accumulation material partition layer, the L shape helps to slow down the impact force and avoid direct damage to the chute barrel wall by the material. Therefore, the accumulation material partition layer improves the self-strength of the first chute and enhances the impact resistance and wear resistance of the first chute itself. On the other hand, since the material is relatively fine and some packaging bags of the material will leak, especially during the impact process, some smaller materials can gradually accumulate and get stuck in the accumulation material area to fill the gaps. After that, when the material impacts on the accumulation material partition layer again, the pressure received by the accumulation material partition layer will also distribute part of the impact force to each smaller material filled inside to a certain extent, so as to further achieve buffering and reduce the impact on the chute. And, after the leaked material is collected in the accumulation material area, it can also reduce the further transportation of the leaked material to the subsequent chutes, thereby reducing the probability of the sliding connection between the subsequent chutes being stuck by the leaked material.

[0009] Preferably, an installation ring is arranged inside the first chute. The installation ring is located below the accumulation material partition layer. An installation rod is arranged at the bottom of the accumulation material partition layer. The installation ring is provided with an installation hole. The bottom of the installation rod extends out of the installation hole and is threadedly connected with an installation nut.

[0010] By adopting the above technical solution, the combined design of the installation ring and the accumulation material partition layer realizes the convenient installation and fixation of the accumulation material partition layer. Specifically: The installation ring is located below the accumulation material partition layer, playing a role of support and positioning to ensure the stability and reliability of the accumulation material partition layer inside the first chute. An installation rod is arranged at the bottom of the accumulation material partition layer, and an installation hole is arranged on the installation ring. The bottom of the installation rod extends out of the installation hole and is threadedly connected with an installation nut. This structure not only facilitates the installation and disassembly of the accumulation material partition layer, but also enables quick replacement after the accumulation material partition layer is impacted and deformed or damaged. The overall design simplifies the maintenance operation, improves the maintenance efficiency, and prolongs the service life of the equipment.

[0011] Preferably, the installation hole is a strip-shaped hole. The installation rod is in clearance fit with the installation hole and can slide along the length direction of the installation hole.

[0012] By adopting the above technical solution, this enables the accumulation material partition layer to shift within the clearance range between the installation hole and the installation rod when impacted by the material, thereby achieving a buffering effect, reducing the impact received by the accumulation material partition layer, and improving its service life and stability.

[0013] Preferably, a buffer retaining ring is sleeved on the outer side wall of the material accumulation partition layer. The buffer retaining ring is located between the outer side wall of the material accumulation partition layer and the inner side wall of the first section of the chute. A buffer washer is provided on the bottom wall of the material accumulation partition layer, and the buffer washer is located between the bottom wall of the material accumulation partition layer and the top wall of the mounting ring.

[0014] By adopting the above technical solution, a buffer retaining ring is sleeved on the outer side wall of the material accumulation partition layer. The buffer retaining ring is located between the outer side wall of the material accumulation partition layer and the inner side wall of the first section of the chute, which can further absorb and disperse the impact force generated by the impact of the material, reducing the direct impact on the inner wall of the first section of the chute. At the same time, a buffer washer is provided on the bottom wall of the material accumulation partition layer, and the buffer washer is located between the bottom wall of the material accumulation partition layer and the top wall of the mounting ring, which can provide an additional buffer effect when the material accumulation partition layer is impacted, further reducing the impact force and improving the stability and durability of the entire system.

[0015] Preferably, an offset mechanism is provided between the diversion baffle and the head funnel. The offset mechanism includes a lateral adjustment drive, a longitudinal adjustment drive, and a rotation drive. The lateral adjustment drive is connected to the head funnel and its drive end is connected to the longitudinal adjustment drive. The drive end of the longitudinal adjustment drive is connected to the rotation drive, and the rotation drive is connected to the diversion baffle.

[0016] By adopting the above technical solution, the setting of the offset mechanism enables the diversion baffle to achieve multi-dimensional position and angle adjustment within the head funnel. Specifically, the lateral adjustment drive, the longitudinal adjustment drive, and the rotation drive are respectively responsible for the horizontal displacement, the up and down displacement, and the rotational movement of the diversion baffle. This can not only be flexibly adjusted according to the characteristics and falling trajectories of different materials, but also ensure that the diversion baffle is always in the best working state, reducing the impact and wear of the material on the chute, and further improving the applicability of this application.

[0017] Preferably, the first section of the chute is also connected with a number of mating chute sections that are sequentially sleeved. The inner edge cross-sections of the first section of the chute and the mating chute sections are all circular.

[0018] By adopting the above technical solution, the traditional square design is prone to material accumulation and jamming at the corners. If material accumulation occurs at a certain corner within a mating chute section, it is likely to cause the adjacent chutes to not contract normally. This application improves the conventional square chute in the related art to a circular design, which is not prone to material accumulation and jamming at the corners, thus making the stability of this application higher during use. In addition, the circular design makes the material easier to be evenly distributed, reducing local stress concentration, thereby reducing the risk of chute damage due to material accumulation, and also facilitating maintenance and cleaning.

[0019] Preferably, the mating relationship between adjacent two of the first section of the chute and the number of mating chute sections is a clearance fit.

[0020] By adopting the above technical solution, the mating relationship between adjacent two of the first chute and several mating chutes is clearance fit, so that when a minor accidental collision occurs, a certain angular offset can be generated between each chute, achieving the effect of releasing the impact kinetic energy and greatly protecting the steel structure of the ship loading telescopic belt conveyor and the position of the head hopper effectively.

[0021] Preferably, guide round steel is arranged on the outer sides of the first chute and several mating chutes, and a pair of guide rail round steel is arranged on the inner sides of several mating chutes, and the guide round steel is slidably connected between the two guide rail round steel.

[0022] By adopting the above technical solution, the round steel is directly installed by welding, which is convenient for processing and the material is more wear-resistant. In the actual processing process, the design of this sliding structure can be carried out at the four equal points in the circumferential direction of the chute to further improve the wear resistance and guiding property between adjacent chutes. The sliding connection design of the guide round steel and the guide rail round steel not only improves the wear resistance and guiding property between adjacent chutes, but also ensures the stable operation of the chute during the telescopic process. This structural design is simple to process and convenient for maintenance, and further prolongs the service life of the chute.

[0023] In a second aspect, the present application provides an application method of a highly stable automatic telescopic chute, adopting the following technical solution: An application method of an automatic telescopic chute, when in use, the first chute is placed vertically, materials are continuously fed from the head hopper, the materials first fall obliquely under the guiding action of the discharging slope surface, then abut against the inclined baffle, and turn at the transition baffle along with the movement of the inclined baffle, and finally adjust the falling direction from the vertical baffle, so that the falling direction of the final materials can be adjusted to be close to vertical falling.

[0024] By adopting the above technical solution, the materials fall obliquely under the guiding action of the discharging slope surface, then abut against the inclined baffle, then move to the transition baffle to turn, and finally adjust the falling direction from the vertical baffle, so that the falling direction of the final materials is adjusted to be close to vertical falling. This design effectively reduces the impact and wear of the materials on the first chute or the subsequent chutes during the falling process, and improves the overall stability and service life of the chute.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The design of the diversion baffle effectively changes the falling path of the materials, making it fall from an inclined state to a state close to vertical falling, significantly reducing the impact and wear of the materials on the first chute and the subsequent chutes, and prolonging the service life of the chute.

[0026] 2. The setting of the material accumulation layer not only enhances the impact resistance of the first chute section but also collects the leaked small particle materials, reducing the impact of these materials on the subsequent chute sections and further improving the stability and reliability of the system.

[0027] 3. The combined design of the mounting ring and the mounting rod makes the material accumulation layer easy to install and replace, facilitating timely repair when the material accumulation layer is damaged and reducing the downtime caused by the failure of the material accumulation layer.

[0030] An embodiment of the present application discloses a highly stable automatic telescopic chute and its application method.

[0031] Embodiment 1 Referring to Figure 1 and Figure 2 A highly stable automatic telescopic chute includes a head funnel 1, a first-section chute 2, and several matching-section chutes 3 that are connected in sequence. The inner edge cross-section of the head funnel 1 is square and is fixedly welded to the first-section chute 2. The inner edge cross-sections of the first-section chute 2 and the matching-section chutes 3 are both circular, so that the material is not easily stuck inside when being conveyed inside the first-section chute 2 or the matching-section chutes 3. The traditional square design is prone to material accumulation and jamming at the corners. If the material accumulates at the corners inside a certain matching-section chute 3, it is likely to cause abnormal shrinkage between adjacent chutes. In this application, the conventional square chute in the related art is improved to a circular design, which is not prone to material accumulation and jamming at the corners, thereby making the stability during the use of this application higher.

[0032] The bottom wall inside the head funnel 1 has an inclined discharging slope 11 to facilitate guiding the material to be conveyed downward obliquely. A guiding baffle 4 is also installed inside the head funnel 1. The guiding baffle 4 includes an inclined baffle 41, a transition baffle 42, and a vertical baffle 43 that are connected in sequence from top to bottom. The inclined baffle 41 is parallel to the discharging slope 11, the vertical baffle 43 is parallel to the axis of the chute, and the transition baffle 42 is connected between the inclined baffle 41 and the vertical baffle 43. The three are integrally formed, and in the actual use state, a part of the vertical baffle 43 can extend into the head funnel 1 to further guide the feeding.

[0033] In the actual application scenario, the head funnel 1 and the first-section chute 2 are fixedly arranged. The topmost matching-section chute 3 is slidably connected to the first-section chute 2, and the remaining several matching-section chutes 3 are slidably connected in sequence. And the lowermost matching-section chute 3 is equipped with a mounting frame 31, and the mounting frame 31 is connected with a unwinding mechanism 32 to control the lifting of the several matching-section chutes 3, so as to realize the telescopic adjustment of the whole device.

[0034] During actual use, the head funnel 1 and the first-section chute 2 are placed vertically, and the material is continuously fed from the head funnel 1. The material first falls obliquely under the guiding action of the discharging slope 11, then abuts against the inclined baffle 41, and turns as it moves to the transition baffle 42, and finally adjusts the falling direction from the vertical baffle 43, so that the final falling direction of the material can be adjusted to be close to vertical falling (parallel to the axis of the first-section chute 2 and the several matching-section chutes 3). Compared with the related art in which the material can only directly impact the side wall of the first-section chute 2 along the discharging slope 11, this application effectively reduces the impact and wear on the first-section chute 2 or the subsequent chutes during the falling process of the material.

[0035] In addition, referring toFigure 3 , inside the first - stage chute 2, there are also several material - accumulating partitions 21 evenly distributed along the axial direction. The material - accumulating partition 21 itself is a ring - shaped structure, but its cross - section is L - shaped. And between the L - shaped inner wall of the material - accumulating partition 21 and the inner wall of the first - stage chute 2, a material - accumulating area is formed. The material - accumulating area is in the shape of an annular groove and opens upward to achieve stable material receiving (specifically referring to scattered powder materials rather than whole boxes or bags of materials). On the one hand, when the material enters the first - stage chute 2, even if the material collides with the material - accumulating partition 21, the L - shape helps to reduce the impact force and avoid direct damage to the inner wall of the first - stage chute 2 by the material. Therefore, the material - accumulating partition 21 improves the self - strength of the first - stage chute 2 and enhances its impact - resistance and wear - resistance performance. On the other hand, because the material is fine and some packaging bags of the material will leak, especially during the impact process, some smaller materials can gradually accumulate and get stuck in the material - accumulating area to fill the voids. After that, when the material hits the material - accumulating partition 21 again, the pressure received by the material - accumulating partition 21 will also distribute part of the impact force to each smaller material filled inside to a certain extent, so as to further achieve buffering and reduce the impact on the chute. Moreover, after the leaked materials are collected in the material - accumulating area, it can also reduce the conveyance of the leaked materials to the subsequent chutes, thereby reducing the probability that the sliding connection between the subsequent chutes is stuck by the leaked materials.

[0036] Refer to Figure 3, the mating relationship between adjacent two of the first chute 2 and several mating chutes 3 is clearance fit. This application adopts this clearance fit method for installation. In case of accidental minor collision, a certain angular offset can occur between each chute, achieving the effect of releasing impact kinetic energy, and can effectively protect the steel structure of the ship loading telescopic belt conveyor and the position of the head hopper 1. Specifically, the top of each mating chute 3 has a reinforcing flange 33. The reinforcing flange 33 is a steel flange, and there is a clearance fit between the reinforcing flange 33 and the mating chute 3 or the first chute 2 located inside it. In addition, lifting flanges 34 are provided on the outer sidewalls of the first chute 2 and several mating chutes 3. The lifting flanges 34 are located above the reinforcing flanges 33. When it is necessary to recover several mating chutes 3, the reinforcing flanges 33 can abut against the lower sides of the lifting flanges 34 to realize the contraction of the mating chutes 3. Therefore, the lifting flange 34 is the upper limit of the relative position relationship between adjacent mating chutes 3. In the publicly known technologies in this field, there are various technical means to realize the lower limit of the relative position relationship between adjacent mating chutes 3 to prevent the adjacent mating chutes 3 from separating, and they are not relevant to the main inventive content of this application, so this specification will not elaborate further. In this application, ultra-high molecular weight polyethylene plates 35 are fixedly provided on the inner side of the reinforcing flange 33 and the top of the inner side of the mating chute 3. The ultra-high molecular weight polyethylene plate 35 is a thermoplastic engineering plastic with a molecular weight higher than 1.5 million. The main advantages lie in toughness, wear resistance, and stress crack resistance. The ultra-high molecular weight polyethylene plates 35 are used to fill the gaps between the adjacent first chute 2 and several mating chutes 3, so as to maintain wear resistance on the premise of buffering.

[0037] Refer to Figure 4 , at the four equal division points along the circumference of the outer sides of the first chute 2 and several mating chutes 3, guiding round bars 5 are welded and fixedly provided. The axial direction of the guiding round bars 5 is consistent with the sliding direction of the several mating chutes 3. Corresponding to the inner sides of each guiding round bar 5 on the inner sides of the several mating chutes 3, a pair of guide rail round bars 51 are welded and fixed. The axial direction of the guide rail round bars 51 is also consistent with the sliding direction of the several mating chutes 3. After assembly, the guiding round bars 5 are inserted between the two guide rail round bars 51 and can slide within the sliding channel formed between the two guide rail round bars 51. In addition, considering the assembly difficulty and subsequent buffering, there is also an activity gap between the guiding round bars 5 and the two guide rail round bars 51. The round bars are directly installed by welding, which is convenient for processing, and the materials are more wear-resistant, further improving the wear resistance and guiding performance between adjacent chutes, and having a certain buffering space when impacted.

[0038] Embodiment 1 also provides an application method of an automatic telescopic chute. When in use, the first chute 2 is placed vertically, and materials are continuously fed from the head hopper 1. The materials first fall obliquely under the guiding action of the discharging slope 11, then abut against the inclined baffle 41, and as the inclined baffle 41 moves to the transition baffle 42, they turn, and finally adjust the falling direction from the vertical baffle 43, so that the falling direction of the final materials can be adjusted to be close to vertical falling. Compared with the related art in which the materials can only directly impact the side wall of the first chute 2 along the discharging slope 11, the impact and wear on the first chute 2 or the subsequent chutes during the falling process of the materials are effectively reduced.

[0039] The implementation principle of Embodiment 1 is: When in use, the first chute 2 is placed vertically, and materials are continuously fed from the head hopper 1. The materials first fall obliquely under the guiding action of the discharging slope 11, then abut against the inclined baffle 41, and as the inclined baffle 41 moves to the transition baffle 42, they turn, and finally adjust the falling direction from the vertical baffle 43, so that the falling direction of the final materials can be adjusted to be close to vertical falling. Compared with the related art in which the materials can only directly impact the side wall of the first chute 2 along the discharging slope 11, the impact and wear on the first chute 2 or the matching chute 3 during the falling process of the materials are effectively reduced.

[0040] Embodiment 2 The difference between Embodiment 2 and Embodiment 1 is that: Referring to Figure 5 , an offset mechanism 6 is further provided between the diversion baffle 4 and the head hopper 1. The offset mechanism 6 includes a lateral adjustment drive 61, a longitudinal adjustment drive 62 and a rotation drive 63. The lateral adjustment drive 61 is connected to the head hopper 1 and its drive end is connected to the longitudinal adjustment drive 62. The drive end of the longitudinal adjustment drive 62 is connected to the rotation drive 63, and the rotation drive 63 is connected to the diversion baffle 4. In this embodiment, both the lateral adjustment drive 61 and the longitudinal adjustment drive 62 are hydraulic cylinders, and the rotation drive 63 is a reduction motor. Through the offset mechanism 6, the relative position and relative angle of the diversion baffle 4 between the head hoppers 1 can be adjusted. In actual application scenarios, the diversion baffle 4 can be adjusted according to the density of different materials and the falling parabolic angle, further improving the applicability of this application.

[0041] Referring to Figure 6, an installation ring 7 is provided below the inner side of the first chute 2 at the positions below a plurality of material accumulation layers 21. The installation ring 7 is fixedly welded to the inner side wall of the first chute 2. An installation rod 71 is fixedly welded to the bottom of the material accumulation layer 21. The installation ring 7 is provided with an installation hole 72, and the installation hole 72 is a strip-shaped hole. The installation rod 71 is in clearance fit with the installation hole 72 and can slide along the length direction of the installation hole 72. The bottom of the installation rod 71 extends out of the installation hole 72 and is threadedly connected with an installation nut 73. Through the above scheme, the convenient installation of the material accumulation layer 21 can be realized, so as to facilitate the replacement after the material accumulation layer 21 is impacted and deformed or damaged, or the quick disassembly and assembly can also be carried out during the cleaning of the leaked material. When the material accumulation layer 21 is impacted, it can shift within the clearance range between the installation hole 72 and the installation rod 71, so as to achieve buffering and reduce the impact received by the material accumulation layer 21.

[0042] Refer to Figure 6 , to further improve the buffering effect, a buffer retaining ring 74 is also sleeved on the outer side wall of the material accumulation layer 21. The buffer retaining ring 74 is located between the outer side wall of the material accumulation layer 21 and the inner side wall of the first chute 2. A buffer washer 75 is provided on the bottom wall of the material accumulation layer 21. The buffer washer 75 is located between the bottom wall of the material accumulation layer 21 and the top wall of the installation ring 7. Both the buffer retaining ring 74 and the buffer washer 75 are made of rubber material to further improve the buffering effect after the material accumulation layer 21 is impacted, and utilize the deformation of the buffer washer 75 and the buffer retaining ring 74 to release the impact kinetic energy.

[0043] Refer to Figure 7 and Figure 8 , in addition to being able to achieve buffering and material storage, the material accumulation layer 21 in this embodiment can also utilize its characteristic of being able to slide and adjust the position to move the lowermost material accumulation layer 21, so as to assist in fixing the diversion baffle 4 when the first chute 2 is in an inclined state. When the first chute 2 is inclined, the offset mechanism 6 can be used to move the diversion baffle 4 close to the side wall of the first chute 2. Specifically, the bottom of the diversion baffle 4 is located inside the lowermost material accumulation layer 21, and other parts of the diversion baffle 4 are located outside other material accumulation layers 21, so as to realize the limit of the bottom of the diversion baffle 4 and improve the stability of the bottom of the diversion baffle 4.

[0044] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
