In the transportation process, coal is easy to produce dust, pollute the working environment, and is not easy to clean, which harms the health of workers.

[0049] In the related art, when coal is added for transportation and when coal falls into the loading equipment, due to the characteristics of the coal itself, a large amount of dust is generated and scattered around after the coal falls downward to the bottom of the scraper conveyor and the loading equipment, a dust raising phenomenon occurs, which pollutes the environment and harms the health of workers.

[0050] Reference is made below to Figures 1-13 A conveying device 1 according to an embodiment of the present application is described.

[0052] The conveying device 1 according to the present application comprises a base 11, a conveying belt 12, a feeding bin 13, a dust suction device 14 and a spraying device 15. The dust suction device 14 is arranged in the feeding bin 13, the spraying device 15 is arranged on the base 11, the dust suction device 14 can suck the airflow in the feeding passage into the inlet of the dust suction device 14, and the spraying device 15 is formed with a spraying opening that can spray towards the conveying belt 12, so that the dust suction device 14 can suck the dust generated when the feeding bin 13 is fed, and the spraying device 15 can spray and humidify the material to be conveyed on the conveying belt 12, thereby improving the dust suppression performance of the conveying device 1. In the related art, when the coal is added and transported and the coal falls into the loading equipment, a large amount of dust is generated and scattered in the surrounding environment, which pollutes the environment and harms the health of the workers. The conveying device 1 according to the present application adopts the dust suction and spraying humidification mode of the dust suction device 14 and the spraying device 15, which avoids the dust scattering of the material to be conveyed during feeding and transportation and the dust raising when the material to be conveyed falls into the loading equipment, thereby optimizing the dust prevention and dust suppression performance of the conveying device 1 during operation and effectively protecting the environment and the health of the workers.

[0053] In addition, in one specific embodiment of the present application, the conveying belt 12 comprises a gear 121, a transmission chain 122 and a scraper 123; wherein the gear 121 is configured as two and rotatably arranged at the two ends of the base 11 in the length direction; the transmission chain 122 is sleeved on at least part of the outer periphery of the two gears 121 and extends along the length direction of the base 11; and the scraper 123 is configured as a plurality of intervals arranged along the extension direction of the transmission chain 122. By arranging the gear 121, the transmission chain 122 and the scraper 123, the gear 121 can rotate and drive the transmission chain 122 to move, and the scraper 123 can move with the transmission chain 122 and push the material to be conveyed to move, thereby realizing the conveying function of the conveying belt 12 to the material to be conveyed.

[0054] In another specific embodiment of the present application, the conveying device 1 further comprises a driving member 18, which is formed with an output shaft, and the output end of the output shaft is connected with the gear 121 to selectively drive the gear 121 to rotate, thereby realizing that the driving member 18 can provide rotating power for the gear 121 to ensure the normal work of the conveying belt 12.

[0055] In addition, in still another specific embodiment of the present application, at least part of the feeding bin 13 gradually reduces in cross section in the direction close to the conveying belt 12, so that the feeding channel can play a guiding role on the material to be conveyed, thereby improving the efficiency of the material to be conveyed from the feeding bin 13 to the conveying belt 12.

[0056] According to one embodiment of the present application, the dust collection device 14 comprises a suction shell 141, a suction fan 142 and a filtering device 143. In this embodiment, the suction shell 141 is arranged in the charging bin 13, and a suction passage 1411 is formed in the suction shell 141, which is communicated with the charging passage and has an outlet communicated with the outside; the suction fan 142 is arranged in the suction passage 1411, and is adapted to generate an airflow flowing from the charging passage to the suction passage 1411, so that when the suction fan 142 works, the airflow generated by the suction fan 142 can guide the dust in the charging bin 13 to flow to the suction passage 1411; and the filtering device 143 is arranged on the suction shell 141 and located at the outlet of the suction passage 1411, and is adapted to filter the airflow entering the outside from the suction passage 1411, so as to filter the dust entrained in the airflow. By arranging the suction shell 141, the suction fan 142 and the filtering device 143, the suction passage 1411 communicated with the charging passage is formed in the suction shell 141, the suction fan 142 is arranged in the suction passage 1411, and the filtering device 143 is arranged at the outlet of the suction passage 1411, so that the suction fan 142 can generate the airflow flowing from the charging passage to the suction passage 1411, and the dust entrained in the airflow in the charging bin 13 can be filtered and collected at the filtering device 143 after sequentially passing through the charging passage and the suction passage 1411, thereby improving the dust reduction capacity during the charging of the charging bin 13 and ensuring the environmental protection and health during the charging and transportation of the material to be transported.

[0057] In addition, in one specific embodiment of the present application, the filtering device 143 comprises a first filter screen 1431 arranged on the suction shell 141 and located at the outlet of the suction passage 1411, and adapted to block the dust in the airflow, so as to realize the filtering effect of the filtering device 143.

[0058] In another specific embodiment of the present application, the first filter screen 1431 is arranged inclinedly in a direction away from the charging passage and close to the conveying belt 12, so as to facilitate the dust on the first filter screen 1431 to fall off from the first filter screen 1431 under the action of gravity when the dust accumulates to a certain amount, thereby realizing the automatic discharge of the dust.

[0059] In still another specific embodiment of the present application, the dust collection device 14 is constructed as two and arranged opposite to each other on the charging bin 13, so that by constructing the dust collection device 14 as two, the dust collection path of the dust collection device 14 is increased, thereby further improving the dust collection efficiency and effect of the dust collection device 14.

[0060] According to one embodiment of the present application, at least part of the suction passage 1411 is arranged to be inclined in a direction away from the feeding passage and towards the conveying belt 12. It can be understood that when the feeding bin 13 is feeding, the material to be conveyed first falls into the feeding bin 13 and then falls from the feeding passage in the feeding bin 13 onto the conveying belt 12. Dust generated by the material to be conveyed falling into the feeding bin 13 will drift in a direction away from the conveying belt 12. Therefore, by arranging at least part of the suction passage 1411 to be inclined in a direction away from the feeding passage and towards the conveying belt 12, on the one hand, the direction of the airflow generated by the suction fan 142 and flowing from the feeding passage to the suction passage 1411 can be adapted to the direction in which the dust itself drifts, so that the dust can enter the suction passage 1411 along the airflow in a timely and rapid manner, thereby facilitating the improvement of the dust suction efficiency and effect of the dust suction device 14. On the other hand, by arranging at least part of the suction passage 1411 to be inclined in a direction away from the feeding passage and towards the conveying belt 12, when the feeding bin 13 is feeding, the material to be conveyed can smoothly fall along the feeding passage and onto the conveying belt 12, without entering the suction passage 1411, thereby ensuring the smoothness of the airflow in the suction passage 1411 and ensuring that the feeding bin 13 can normally perform the feeding and conveying work.

[0061] According to one embodiment of the present application, the suction passage 1411 comprises an inlet section 14111, an inclined section 14112, and a containing cavity. In this embodiment, the inlet section 14111 is in communication with the feeding passage. In this embodiment, the inclined section 14112 is connected to the inlet section 14111 and is arranged to be inclined in a direction away from the feeding passage and towards the conveying belt 12. In this embodiment, the containing section 14113 is in communication with the inclined section 14112, and the containing section 14113 is provided with a suction passage 1411 outlet in communication with the outside. The suction fan 142 is arranged between the inclined section 14112 and the containing section 14113. By arranging the inlet section 14111, the inclined section 14112, and the containing cavity, when the suction fan 142 is working, the airflow in the feeding bin 13 can pass through the feeding passage, the inlet section 14111, the inclined section 14112, and the containing cavity in sequence under the suction action of the suction fan 142. Since the containing section 14113 is provided with a suction passage 1411 outlet in communication with the outside, the dust in the final airflow can be filtered smoothly at the filtering device 143 located at the suction passage 1411 outlet, and the clean airflow after being filtered by the filtering device 143 can enter the outside through the suction passage 1411 outlet, thereby realizing that the dust suction device 14 has a good dust suction effect.

[0062] In addition, in one specific embodiment of the present application, the suction passage 1411 is formed with a clamping portion 14114 extending away from the inner wall of the suction passage 1411 at the end of the outer wall of the charging passage, and the clamping portion 14114 is adapted to abut against the inner wall of the charging passage to realize the assembly between the dust collection device 14 and the charging bin 13. By arranging the clamping portion 14114, the dust collection device 14 and the charging bin 13 are detachably connected, thereby improving the installation and maintenance convenience of the dust collection device 14 and the charging bin 13.

[0063] According to one embodiment of the present application, the containing section 14113 is formed with a collection cavity adapted to collect dust. When the suction fan 142 is working, the airflow in the charging bin 13 can enter into the containing section 14113 after sequentially passing through the charging passage, the inlet section 14111 and the inclined section 14112, at which time the dust can be filtered and collected in the collection cavity of the containing section 14113 under the filtering effect of the filtering device 143. Therefore, by forming the containing section 14113 with the collection cavity adapted to collect dust, the collection cavity can collect the filtered dust to realize the separation of the dust and the airflow, thereby ensuring that the airflow does not affect the dust collection effect of the dust collection device 14, and realizing that the collection cavity can directionally discharge the collected dust to ensure the continuous work of the dust collection device 14.

[0064] According to one embodiment of the present application, the conveying device 1 further comprises a guide pipe 16, one end of the guide pipe 16 being connected with the collection cavity, and the other end of the guide pipe 16 being selectively open to the conveying belt 12, so that when the dust collected in the collection cavity accumulates to a certain amount, the other end of the guide pipe 16 can be open to the conveying belt 12, at which time the dust in the collection cavity can enter into the guide pipe 16 from the collection cavity and finally move along the guide pipe 16 to the conveying belt 12. By arranging the guide pipe 16, the guide pipe 16 can provide a discharge passage for the dust collected in the collection cavity and guide the discharge of the dust, thereby realizing that the dust collected in the collection cavity can be directionally discharged to the conveying belt 12 to ensure the continuous dust collection work of the dust collection device 14. In addition, the guide pipe 16 guides the dust to the conveying belt 12, which also ensures the environmental protection of the dust discharge and avoids the waste of resources, effectively improves the conveying integrity of the material to be conveyed, and optimizes the economic benefits of the conveying device 1.

[0065] According to one embodiment of the present application, the spraying device 15 comprises a spraying shell 151 and a water tank 152. The spraying shell 151 in this embodiment can provide mounting positions for some other components of the spraying device 15, and can support, fix and protect some other components of the spraying device 15. The spraying shell 151 is arranged on the outer periphery of the conveying belt 12, and the spraying shell 151 is formed with a first spraying opening 1511 facing the conveying belt 12; in this embodiment, the water tank 152 is formed with a water storage cavity, and the water storage cavity is in communication with the first spraying opening 1511, and the water storage cavity can provide spraying water for the first spraying opening 1511. By arranging the spraying shell 151 and the water tank 152, the first spraying opening 1511 facing the conveying belt 12 is formed on the spraying shell 151, and the water storage cavity in communication with the first spraying opening 1511 is formed in the water tank 152, so that the water storage cavity can provide spraying water for the first spraying opening 1511, and the first spraying opening 1511 can spray and humidify the material to be conveyed and dust on the conveying belt 12. The particle specific gravity of the material to be conveyed and dust increases under the humidification of the first spraying opening 1511, so as to avoid dust diffusion during the conveying of the material to be conveyed by the conveying belt 12, and during the conveying of the material to be conveyed to the preset position for loading, thereby effectively improving the dustproof and dust reduction performance of the conveying device 1, and ensuring the health of the environment and workers.

[0066] In addition, in one specific embodiment of the present application, the spraying device 15 further comprises a water guide pipe 154 and a water pump 155; wherein the two ends of the water guide pipe 154 are respectively in communication with the water storage cavity and the input end of the water pump 155; the water pump 155 is arranged on the spraying shell 151, and the output end of the water pump 155 is in communication with the first spraying opening 1511. By arranging the water guide pipe 154 and the water pump 155, the water pump 155 can suck water source in the water storage cavity through the water guide pipe 154 and deliver to the first spraying opening 1511, so as to realize the spraying and humidification performance of the first spraying opening 1511.

[0067] According to one embodiment of the present application, the spraying device 15 further comprises a second spraying part 153, which is arranged on the spraying shell 151 and extends towards the conveying belt 12, and the second spraying part 153 is formed with a second spraying opening 15311 on one side in the conveying direction of the conveying belt. Similarly, the water storage cavity of the water tank 152 can provide spraying water for the second spraying opening 15311. By arranging the second spraying opening 15311, the second spraying opening 15311 can spray and humidify the material to be conveyed and dust on the conveying belt 12, so that the first spraying opening 1511 and the second spraying opening 15311 can respectively humidify the material to be conveyed and dust, thereby enhancing the humidification efficiency and effect of the material to be conveyed and dust, thereby avoiding dust diffusion during the conveying of the material to be conveyed by the conveying belt 12, and when the material to be conveyed is conveyed to the preset position for loading, and further improving the dust prevention and dust reduction performance of the conveying device 1, thereby further ensuring the health of the environment and the workers.

[0068] According to one embodiment of the present application, the second spraying part 153 is formed with a guide slope 1533 on the side away from the second spraying opening 15311. After the material to be conveyed falls from the feeding bin 13 onto the conveying belt 12, the conveying belt 12 moves to drive the material to be conveyed to move, and when the material to be conveyed moves to contact the second spraying part 153, the material to be conveyed will first contact the guide slope 1533 on the side away from the second spraying opening 15311 of the second spraying part 153. The guide slope 1533 can reduce the contact area between the second spraying part 153 and the material to be conveyed. Therefore, by forming the guide slope 1533 on the side away from the second spraying opening 15311 of the second spraying part 153, the guide slope 1533 can reduce the resistance of the second spraying part 153 passing through the inside of the material to be conveyed, so that the second spraying opening 15311 on the second spraying part 153 can easily spray and humidify the inside of the material to be conveyed, thereby expanding the humidification range of the spraying device 15 on the material to be conveyed, and further improving the dust prevention and dust reduction performance of the conveying device 1 during the transportation of the material to be conveyed and when the material to be conveyed is conveyed to the preset position for loading.

[0069] In addition, in one specific embodiment of the present application, the second spraying part 153 comprises a body 1531 and a shell 1532; the body 1531 is arranged on the spraying shell 151 and extends towards the conveying belt 12, and one side of the body 1531 is formed with the second spraying opening 15311; the shell 1532 is formed with a clamping groove adapted to abut at least part of the surface of the body 1531, and the shell 1532 and the second spraying opening 15311 are arranged away from each other and formed with the guide slope 1533.

[0076] In still another specific embodiment of the present application, the spraying device 15 further comprises a water level detection component 156, a water inlet pipeline 157, a valve body 158, and a filter 159; wherein the water level detection component 156 is accommodated in the water storage cavity and is adapted to detect the water level height in the water storage cavity; the outlet and the inlet of the water inlet pipeline 157 are respectively communicated with the water storage cavity and the outside, the water inlet pipeline 157 can selectively deliver the water source into the water storage cavity; the valve body 158 is arranged in the water inlet pipeline 157, the valve body 158 is adapted to selectively open or close the water inlet pipeline 157 according to the detection result of the water level detection component 156 to realize that the water inlet pipeline 157 can only deliver the water source into the water storage cavity when the water source in the water storage cavity is insufficient, so as to guarantee the spraying work of the spraying device 15; the filter 159 is movably arranged in the water tank 152 and is adapted to cover the open end of the water storage cavity, the filter 159 can filter the water flow flowing out of the water outlet 1111 of the water guide track to realize the further purification of the recovered water flow, so as to further optimize the spraying and humidifying effect of the spraying device 15 on the material to be conveyed.

[0077] The water level detection component 156 in the above embodiment comprises a first shell 1561, a second shell 1562, a rod body 1563, and a control button 1564. The first shell 1561 is arranged on the bottom wall of the water storage cavity and forms a first cavity adapted to communicate with the water storage cavity. One end of the second shell 1562 is connected with the end of the first shell 1561, and the other end extends away from the first shell 1561. The other end of the second shell 1562 forms a supporting leg 15621 extending towards the side wall of the water storage cavity and connected with the water tank 152. The second shell 1562 forms a second cavity. The rod body 1563 is arranged between the first shell 1561 and the second shell 1562. One end of the rod body 1563 is provided with a float 15631 movably accommodated in the cavity. The control button 1564 is arranged on the other end of the second shell 1562 and accommodated in the second cavity. The control button 1564 is opposite to the other end of the rod body 1563 and selectively abuts against the end surface of the rod body 1563. The control button 1564 is adapted to control the valve body 158 to open or close the water inlet pipeline 157. The working process of the water level detection component 156 is as follows: the float 15631 can float on the water surface in the water storage cavity due to its own characteristics. When the water level height in the water storage cavity is at the preset sufficient water level, the float 15631 makes the other end of the rod body 1563 abut against the control button 1564 under the buoyancy. At this time, the control button 1564 can control the valve body 158 to close the water inlet pipeline 157. When the water level height in the water storage cavity decreases below the preset sufficient water level, the float 15631 moves downward with the water surface, and the float 15631 drives the other end of the rod body 1563 to move downward, so that the end surface of the rod body 1563 is separated from the control button 1564. At this time, the control button 1564 can control the valve body 158 to open the water inlet pipeline 157 to deliver water source into the water storage cavity until the water level height in the water storage cavity restores to the preset sufficient water level, thereby realizing the continuous spraying and humidifying work of the spraying device 15.
