Description

Technical Field

[0001] The invention relates to the technical field of port loading and unloading, and in particular to a material distributing mechanism and a material distributing system for a ship unloader. Background Art

[0002] Most bulk cargo terminals use bridge grab ship unloaders as the main equipment for unloading coal and ore. The material distribution system is an important part of the bridge grab ship unloader. The quality of the material distribution system design seriously affects the transportation efficiency and operation safety of the entire system. The material distribution system is mainly composed of a three-way distributor and a drop pipe. The inlet end of the three-way distributor is connected to the outlet end of the central large funnel, and the upper ends of the two drop pipes are respectively connected to the two outlet ends of the three-way distributor. The material reaches different conveyor belts through the drop pipes. The two outlet ends of the three-way distributor can be alternately connected and cut off by flipping the baffle. In the existing ship unloader material distribution system (such as a bridge grab ship unloader material distribution system disclosed in application No. 201620203823.9), the bottom of the baffle is rotatably connected to the distributor via a rotating shaft. The driver drives the baffle to rotate, so that the baffle alternately blocks the two outlet ends of the three-way distributor to achieve material diversion. Since there is a gap between the bottom of the baffle and the inner wall at the intersection of the two outlet ends of the distributor, when the material enters the drop pipe from the distributor, it is easy to get stuck in the gap, affecting the flexibility of the baffle rotation, and even causing the baffle to be unable to rotate normally, affecting the normal operation of the distribution system. Summary of the invention The purpose of the present invention is to overcome the above-mentioned technical deficiencies and propose a material dividing mechanism and a ship unloader material dividing system to solve the technical problem in the prior art that there is easily a gap between the bottom of the baffle and the inner wall at the intersection of the two outlet ends of the divider. When the material enters the drop pipe from the divider, it is easy to get stuck in the gap, affecting the flexibility of the baffle rotation, and even causing the baffle to be unable to rotate normally, affecting the normal operation of the material dividing system.

[0003] In order to achieve the above technical purpose, the technical solution of the present invention provides a material distribution mechanism, comprising: The material dividing part includes a divider, a baffle and a driving assembly. The divider has an inverted Y-shaped material dividing cavity. The material dividing cavity has a feed channel and two discharge channels. The middle part of the baffle is located at the intersection of the feed channel and the two discharge channels. The driving assembly is connected to the middle part of the baffle and is used to drive the baffle to rotate around the rotating axis in the middle to adjust the inclination angle of the baffle and make the baffle alternately block the corresponding discharge channels.

[0004] Furthermore, the two discharge channels are arranged opposite to each other on both sides of the feed channel.

[0005] Furthermore, the material distribution part also includes two side plates, the two side plates are fixedly connected to the baffle plate, the baffle plate and the two side plates enclose a material receiving trough, the top opening of the material receiving trough is connected to the feed channel, and the openings at both ends of the material receiving trough are respectively connected to the corresponding discharge channels.

[0006] Furthermore, the side panel is a semicircular structure.

[0007] Furthermore, the material distribution part also includes a material guide pipe, which is arranged in the feed channel, the inlet end of the material guide pipe is connected to the inlet end of the feed channel, and the outlet end of the material guide pipe is connected to the top opening of the material receiving trough.

[0008] Furthermore, the diameter of the material guiding pipe gradually decreases from top to bottom.

[0009] Furthermore, the material distribution part also includes a supporting frame and a lap frame, wherein the supporting frame is arranged in the feed channel and fixedly connected to the material distributor, the supporting frame is close to the inlet end of the feed channel, the lap frame is sleeved on the outer wall of the material guide tube and fixedly connected to the material guide tube, the lap frame is close to the upper end of the material guide tube, and when the material guide tube is placed in the feed channel, the lap frame is placed on the supporting frame.

[0010] Furthermore, the driving assembly is arranged outside the distributor, and the driving assembly includes a connecting rod and a telescopic driving member. One end of the connecting rod is fixedly connected to one end of the rotating shaft of the baffle, the fixed end of the telescopic driving member is hinged to the distributor, and the output end of the telescopic driving member is hinged to the other end of the connecting rod for driving the connecting rod to swing back and forth.

[0011] Furthermore, the material distribution mechanism also includes a dropping part, which includes two dropping pipes and two buffer components. The upper ends of the two dropping pipes are respectively connected to the outlet ends of the corresponding discharge channels, and the two buffer components are respectively arranged in the corresponding dropping pipes to slow down the bottoming speed of the material.

[0012] On the other hand, the present invention also provides a material distributing system for a ship unloader, comprising the above-mentioned material distributing mechanism.

[0013] Compared with the prior art, the beneficial effects of the present invention include: when in use, by manipulating the driving assembly, the driving assembly can drive the baffle to rotate around the rotating axis in the middle thereof, so that the inclination angle of the baffle can be adjusted, so that a part of the baffle blocks the corresponding discharge channel. At this time, the other discharge channel is in a conducting state, and the material flows along the feed channel and the discharge channel and reaches the corresponding conveyor belt. In this material distribution mechanism, since the middle part of the baffle is located at the intersection of the feed channel and the two discharge channels, when the discharge channel is in a conducting state, the end of the corresponding baffle is in a low position. At this time, there is a sufficient distance between the end of the baffle and the intersection of the two discharge channels, and the gap between the middle part of the baffle and the inner wall of the intersection of the two discharge channels will be covered by the baffle itself. When the material enters the discharge channel from the feed channel, it will not be stuck in the gap, thereby ensuring the flexibility of the rotation of the baffle rotating axis and ensuring the normal operation of the material distribution system.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] The present invention provides a material distribution mechanism, the structure of which is as follows: Figure 1 - Figure 4 As shown, it includes a distributing part 100, and the distributing part 100 includes a distributor 110, a baffle 120 and a driving assembly 130. The distributor 110 has an inverted Y-shaped distributing chamber 111, and the distributing chamber 111 has a feed channel 1111 and two discharge channels 1112. The middle part of the baffle 120 is located at the intersection of the feed channel 1111 and the two discharge channels 1112, and the two parts of the baffle 120 are respectively located in the corresponding discharge channels 1112. The driving assembly 130 is connected to the middle part of the baffle 120, and is used to drive the baffle 120 to rotate around the central rotating axis to adjust the inclination angle of the baffle 120, and make the two parts of the baffle 120 alternately block the corresponding discharge channels 1112.

[0017] When in use, the inlet end of the feed channel 1111 is detachably connected to the outlet end of the central large funnel, and the appropriate discharge channel 1112 is selected according to the conveyor belt to which the material needs to arrive. By manipulating the drive assembly 130, the drive assembly 130 can drive the baffle 120 to rotate around the rotating axis in the middle, so that the inclination angle of the baffle 120 can be adjusted, so that a part of the baffle 120 blocks the corresponding discharge channel 1112. At this time, the other discharge channel 1112 is in a conducting state, and the material flows along the feed channel 1111 and the discharge channel 1112 and reaches the corresponding conveyor belt. In this material distribution mechanism, since the middle part of the baffle 120 is located in the feed channel 11 11 and the intersection of the two discharge channels 1112, and the two parts of the baffle 120 are respectively located in the corresponding discharge channels 1112. When the discharge channels 1112 are in a conducting state, the corresponding end of the baffle 120 is in a low position. At this time, there is a sufficient distance between the end of the baffle 120 and the intersection of the two discharge channels 1112. The gap between the middle part of the baffle 120 and the inner wall of the intersection of the two discharge channels 1112 will be covered by the baffle 120 itself. When the material enters the discharge channel 1112 from the feed channel 1111, it will not be stuck in the gap, which ensures the flexibility of the rotation of the rotating shaft of the baffle 120 and the normal operation of the material distribution system.

[0018] As a preferred embodiment, please refer to Figure 4 The two discharge channels 1112 are relatively arranged on both sides of the feed channel 1111, so that the two parts of the baffle 120 can correspond to the two discharge channels 1112 one by one, thereby improving the material blocking effect.

[0019] As a preferred embodiment, please refer to Figure 3 and Figure 4The material distribution part 100 also includes two side plates 140, which are relatively arranged above the baffle 120 and fixedly connected to the baffle 120. The baffle 120 and the two side plates 140 are enclosed to form a material receiving trough, and the top opening of the material receiving trough is connected to the feed channel 1111, and the openings at both ends of the material receiving trough are respectively connected to the corresponding discharge channels 1112. Since there is a gap between the two side walls of the baffle 120 and the two inner side walls of the distributor 110, it is easy for the material to get stuck when it enters the discharge channel 1112 from the feed channel 1111. If the material enters the gap, it will also affect the flexibility of the baffle 120 in rotating, and even cause the baffle 120 to be unable to rotate normally, affecting the normal operation of the material distribution system. In this material distribution mechanism, the material in the feed channel 1111 first falls into the material receiving trough, and then falls into the discharge channel 1112. The material in the feed channel 1111 can be received by the material receiving trough, so that the material will not be stuck in the gap between the two side walls of the baffle 120 and the two inner walls of the divider 110, which further ensures the flexibility of the rotation of the rotating shaft of the baffle 120 and ensures the normal operation of the material distribution system.

[0020] As a preferred embodiment, please refer to Figure 3 The side plate 140 is a semicircular structure. Since the rotation path of the baffle 120 is a semicircular arc, the side plate 140 is set to a semicircular structure to ensure that the side plate 140 will not collide with the inner wall of the distributor 110 during the rotation process.

[0021] As a preferred embodiment, please refer to Figure 3 and Figure 5 The material distribution part 100 also includes a material guide pipe 150, which is arranged in the feed channel 1111. The inlet end of the material guide pipe 150 is connected with the inlet end of the feed channel 1111, and the outlet end of the material guide pipe 150 is connected with the top opening of the material receiving trough. The material entering the inlet end of the feed channel 1111 can be guided to the material receiving trough through the material guide pipe 150 to prevent the material from scattering outside the material receiving trough, thereby improving the material receiving effect of the material receiving trough.

[0022] As a preferred embodiment, please refer to Figure 3 and Figure 5 The diameter of the material guiding pipe 150 gradually decreases from top to bottom, thereby improving the material guiding effect of the material guiding pipe 150 .

[0023] As a preferred embodiment, please refer to Figure 3 and Figure 5The material distribution part 100 also includes a supporting frame 160 and a lap frame 170. The supporting frame 160 is arranged in the feeding channel 1111 and is fixedly connected to the distributor 110. The supporting frame 160 is close to the inlet end of the feeding channel 1111. The lap frame 170 is sleeved on the outer wall of the guide tube 150 and is fixedly connected to the guide tube 150. The lap frame 170 is close to the upper end of the guide tube 150. When the guide tube 150 is placed in the feeding channel 1111, the lap frame 170 is placed on the supporting frame 160, so that the guide tube 150 can be quickly disassembled and assembled.

[0024] As a preferred embodiment, please refer to Figure 3 and Figure 4 The driving component 130 is arranged outside the distributor 110, and the driving component 130 includes a connecting rod 131 and a telescopic driving member 132. One end of the connecting rod 131 is fixedly connected to one end of the rotating shaft of the baffle 120, and the fixed end of the telescopic driving member 132 is hinged to the distributor 110. The output end of the telescopic driving member 132 is hinged to the other end of the connecting rod 131, and is used to drive the connecting rod 131 to swing back and forth. By manipulating the telescopic driving member 132, the output end of the telescopic driving member 132 can perform a telescopic action, thereby driving the connecting rod 131 to swing back and forth, and driving the baffle 120 to rotate back and forth. The telescopic driving member 132 can be directly connected to the other end of the connecting rod 131 by using a suitable type of cylinder, or can be connected to the other end of the connecting rod 131 through a transmission mechanism such as a gear set and a pulley set.

[0025] As a preferred embodiment, please refer to Figure 1 and Figure 2 The material distribution mechanism also includes a material dropping part 200, which includes two material dropping pipes 210 and two buffer components 220. The upper ends of the two material dropping pipes 210 are respectively connected to the outlet ends of the corresponding material discharge channels 1112. The two buffer components 220 are respectively arranged in the corresponding material dropping pipes 210 to slow down the bottoming speed of the material. The material can be guided to different conveyor belts through the two material dropping pipes 210. Since the material flows out of the material dropping pipes 210 and falls on the conveyor belt, the material has a high speed when it reaches the conveyor belt, which will cause a considerable impact on the conveyor belt and easily damage the conveyor belt, causing cracks in the belt. The buffer component 220 can slow down the bottoming speed of the material, thereby reducing the impact of the material on the conveyor belt and extending the service life of the conveyor belt.

[0026] As a preferred embodiment, please refer to Figure 2The drop pipe 210 has an inclined section 211 and a vertical section 212 that are interconnected. The upper end of the inclined section 211 is connected to the outlet end of the discharge channel 1112. The buffer assembly 220 includes a plurality of buffer plates 221. Each of the buffer plates 221 is alternately and obliquely arranged in the vertical section 212. When the material enters the vertical section 212 from the inclined section 211, it will be blocked and buffered from top to bottom by each layer of the buffer plates 221, thereby effectively reducing the bottoming speed of the material.

[0027] Please refer to Figure 1 and Figure 2 Based on the above-mentioned material dividing mechanism, the present invention also provides a ship unloader material dividing system, including the above-mentioned material dividing mechanism.

[0028] In order to better understand the present invention, the following Figure 1 - Figure 5 The working principle of the technical solution of the present invention is described in detail: When in use, the inlet end of the feed channel 1111 is detachably connected to the outlet end of the central large funnel, and the appropriate discharge channel 1112 is selected according to the conveyor belt to which the material needs to arrive. By manipulating the telescopic drive member 132, the output end of the telescopic drive member 132 can perform a telescopic action, thereby driving the connecting rod 131 to swing back and forth, and driving the baffle 120 to rotate back and forth, so that the inclination angle of the baffle 120 can be adjusted, so that a part of the baffle 120 blocks the corresponding discharge channel 1112. At this time, the other discharge channel 1112 is in a conducting state, and the material flows along the feed channel 1111, the discharge channel 1112 and the drop tube 210 and reaches the corresponding conveyor belt. The material enters the vertical section 212 from the inclined section 211 and is buffered from top to bottom by each layer of the buffer plates 221 Blocking and buffering, thereby effectively reducing the bottoming speed of the material. In this material distribution mechanism, since the middle part of the baffle 120 is located at the intersection of the feed channel 1111 and the two discharge channels 1112, and the two parts of the baffle 120 are respectively located in the corresponding discharge channels 1112, when the discharge channel 1112 is in a conducting state, the corresponding end of the baffle 120 is in a low position. At this time, there is a sufficient distance between the end of the baffle 120 and the intersection of the two discharge channels 1112, and the gap between the middle part of the baffle 120 and the inner wall of the intersection of the two discharge channels 1112 will be covered by the baffle 120 itself. When the material enters the discharge channel 1112 from the feed channel 1111, it will not be stuck in the gap, which ensures the flexibility of the rotation of the rotating shaft of the baffle 120 and the normal operation of the material distribution system.

[0029] The material distribution mechanism and the material distribution system of the ship unloader provided by the present invention have the following beneficial effects: (1) Since the material flows out from the drop tube 210 and falls on the conveyor belt, the material has a high speed when it reaches the conveyor belt, which will cause a considerable impact on the conveyor belt, and it is easy to damage the conveyor belt, causing cracks on the belt. The buffer plates 221 of each layer can block and buffer the material, slow down the speed at which the material touches the bottom, thereby reducing the impact of the material on the conveyor belt and extending the service life of the conveyor belt; (2) In the present material distributing mechanism, the material in the feed channel 1111 first falls into the material receiving trough, and then falls into the material discharging channel 1112. The material in the feed channel 1111 can be received by the material receiving trough, so that the material will not be stuck in the gap between the two side walls of the baffle 120 and the two inner side walls of the distributor 110, further ensuring the flexibility of the rotation of the rotating shaft of the baffle 120 and ensuring the normal operation of the material distributing system; (3) In the present material distribution mechanism, since the middle portion of the baffle 120 is located at the intersection of the feed channel 1111 and the two discharge channels 1112, and the two portions of the baffle 120 are respectively located in the corresponding discharge channels 1112, when the discharge channels 1112 are in a conducting state, the corresponding end portion of the baffle 120 is in a low position. At this time, there is a sufficient distance between the end portion of the baffle 120 and the intersection of the two discharge channels 1112. The gap between the middle portion of the baffle 120 and the inner wall of the intersection of the two discharge channels 1112 will be covered by the baffle 120 itself. When the material enters the discharge channel 1112 from the feed channel 1111, it will not be stuck in the gap, thereby ensuring the flexibility of the rotation of the rotating shaft of the baffle 120 and ensuring the normal operation of the material distribution system.
