Description

Technical Field

[0001] The utility model relates to the technical field of material feeding, in particular to a material transportation system. Background Art

[0002] At present, in the field of mining engineering, especially in the transportation system of ore and other material feeds, transfer devices and sorting devices are set up. The ore is transported to the sorting device through the transfer device and sorted by the sorting device. The material processing capacity of the sorting device depends not only on the processing capacity of the sorting device, but also on the loading rate of the transfer device. In order to ensure that the transfer device and the sorting device can operate at a higher efficiency, it is necessary to ensure the degree of connection between the transfer device and the sorting device, and give full play to the maximum processing capacity of all devices under the premise of ensuring the stable operation of the whole system.

[0003] However, in the prior art, due to actual production conditions, the sorting process is usually adjusted to adapt to changes in materials, or the device is maintained and updated, which will cause changes in the connection between the transfer device and the sorting device, resulting in a worse connection between the transfer device and the sorting device. When the loading rate of the transfer device is greater than that of the sorting device, the material will continue to accumulate at the sorting device, causing material blockage, causing the sorting device to overload and reduce the stability of the overall system operation, thereby causing the overall efficiency of the system to decrease, which has an adverse effect on production.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] like Figure 1 As shown, the embodiment of the utility model provides a material transportation system, which includes a transfer device 10, a feeding device 20 and an overflow device 30. The transfer device 10 is connected to the upstream feeding device and is used to introduce materials into the material transportation system. The feeding device 20 is connected to the downstream sorting system and is used to export materials from the material transportation system. The inlet of the feeding device 20 is provided with a storage cavity. The overflow device 30 is arranged between the transfer device 10 and the feeding device 20. The overflow device 30 has a flow channel 301 and an overflow channel 302 that are connected to each other. The flow channel 301 has a feed port 3011 and a discharge port 3012 that are arranged at intervals in the vertical direction. The transfer device 10 is arranged corresponding to the feed port 3011, and the storage cavity is arranged corresponding to the discharge port 3012. The overflow channel 302 has an overflow port 3021, and the overflow port 3021 is arranged between the feed port 3011 and the discharge port 3012.

[0031] By applying the technical solution of the utility model, the material transferred by the transfer device 10 can flow to the feeding device 20 through the flow channel 301 of the overflow device 30 to realize the transfer of the material. By setting the overflow device 30 between the transfer device 10 and the feeding device 20, during the material transfer process, when the material processing capacity of the transfer device 10 is greater than the material processing capacity of the feeding device 20, as the transfer device 10 and the feeding device 20 operate, the material will continue to accumulate at the inlet of the feeding device 20 and gradually accumulate in the flow channel 301. When the material accumulates to the overflow port 3021, the subsequent material flowing into the overflow device 30 can flow out through the overflow channel 302, preventing the material from continuously accumulating at the feeding device 20 and causing the feeding device 20 to overload. Through the technical solution provided by the present application, the feeding device 20 can be prevented from being blocked by materials, and the accumulated materials at the feeding device 20 can be discharged without stopping the operation of the transfer device 10, ensuring the stable operation of the feeding device 20 and improving the operation efficiency of the overall transportation system.

[0032] refer to Figure 2As shown, the overflow device 30 includes a body 31, a guide groove 32 and an overflow groove 33. The body 31 has a flow chamber 311, one end of the flow chamber 311 has a feed port 3011, the guide groove 32 is arranged at one end of the flow chamber 311 away from the feed port 3011, the guide groove 32 is connected with the flow chamber 311, the end of the guide groove 32 away from the flow chamber 311 has a discharge port 3012, the overflow groove 33 is arranged on the side wall of the body 31, and is connected with the flow chamber 311, and the end of the overflow groove 33 connected with the flow chamber 311 forms an overflow port 3021. The material can enter the circulation cavity 311 through the feed port 3011 of the main body 31, and flow to the discharge port 3012 through the circulation cavity 311. When the material processing capacity of the transfer device 10 is greater than the material processing capacity of the feeding device 20, the material will continue to accumulate in the guide groove 32. When the material accumulates to the overflow port 3021, the material can all flow to the overflow groove 33 through the circulation cavity 311, preventing the material from continuing to flow to the feeding device 20, thereby ensuring the stable operation of the feeding device.

[0033] Specifically, the axis of the guide groove 32 and the axis of the body 31 have an angle in the vertical direction. Through the above arrangement, the guide groove 32 is inclined relative to the vertical direction, so that the materials accumulated in the guide groove 32 can flow out of the guide groove 32 more smoothly with the operation of the feeding device 20. In the actual production environment of the coal mine, materials such as ore and gangue are irregular blocks. By setting the axis of the guide groove 32 and the axis of the body 31 to have an angle in the vertical direction, it is possible to prevent the material from getting stuck in the guide groove 32, improve the diversion effect of the guide groove 32, and at the same time, the inner wall of the guide groove 32 can also buffer the material, reduce the impact of the material on the feeding device 20, and further improve the stability of the operation of the feeding device 20.

[0034] In a specific embodiment of the present application, refer to Figure 2 As shown, the included angle between the axis of the guide groove 32 and the axis of the main body 31 in the vertical direction is α, 30°≤α≤80°. When α<30°, the included angle between the axis of the guide groove 32 and the axis of the main body 31 in the vertical direction is too small, the guide groove 32 has a poor guiding effect on the material, and the material is also easy to directly fall to the feeding device 20 through the guide groove 32, causing an impact on the feeding device 20; when α>80°, the included angle between the axis of the guide groove 32 and the axis of the main body 31 in the vertical direction is too large, and the material cannot be guided, and the material is not easy to flow out of the guide groove 32. In the present application, by setting 30°≤α≤80°, the guiding effect and buffering effect of the guide groove 32 can be guaranteed. Specifically, α can be set to 30°, 45°, 60° or 80°.

[0035] In some specific embodiments of the present application, a plurality of overflow grooves 33 are provided, and the plurality of overflow grooves 33 are arranged in a circular manner in the horizontal direction on the side wall of the body 31. Through the above arrangement, the discharge effect of the overflow groove 33 can be improved, and the phenomenon of material blockage in the overflow groove 33 can be prevented. Specifically, the overflow grooves 33 can be set to 2 or 3, etc., as long as the total flow area of ​​the plurality of overflow grooves 33 can be increased.

[0036] In some other embodiments of the present application, a plurality of overflow grooves 33 are provided, and one end of the plurality of overflow grooves 33 together form an overflow port 3021 .

[0037] refer to Figure 2 and Figure 3 As shown, a blocking device is provided at the overflow port 3021, and the blocking device includes a baffle 41, and the baffle 41 has a blocking state and an open state that are relatively set. When the baffle 41 is in the blocking state, the baffle 41 blocks the overflow port 3021, and the material can flow to the feeding device 20 through the circulation channel 301. When the material accumulates in the circulation channel 301, the baffle 41 can be switched to the open state, and the baffle 41 avoids the overflow port 3021, and the material can flow out of the overflow device 30 through the overflow channel 302. Through the above arrangement, during the material transfer process, when the material processing capacity of the transfer device 10 is less than or equal to the material processing capacity of the feeding device 20, the baffle 41 can be switched to the blocking state to prevent the material from flowing out of the overflow device 30 through the overflow port 3021, thereby ensuring the working efficiency of the overall transportation system.

[0038] Specifically, the blocking device further includes a motor 42 and a drive shaft 43, the drive shaft 43 is disposed on the side wall of the overflow tank 33, the baffle 41 is fixedly disposed on the drive shaft 43, and is drivingly connected to the motor 42 and the drive shaft 43, and the baffle 41 can rotate under the drive shaft 43 to switch between the open state and the blocked state. Through the above arrangement, the baffle 41 is driven to rotate by the motor 42 and the drive shaft 43, which can facilitate the control of the blocking device and facilitate timely adjustment of the switching of the baffle 41 between the open state and the blocked state.

[0039] Furthermore, the material transportation system also includes a control device, which includes a weight sensor, a weighing device 50 and a controller. The weight sensor is arranged on the transfer device 10, and is used to detect the feeding amount of the upstream feeding device. The weighing device 50 is arranged downstream of the feeding device 20, and is used to detect the feeding amount entering the downstream sorting device. The controller is electrically connected with the weight sensor, the weighing device 50 and the motor 42. The controller can compare the weight information of the weight sensor and the weighing device 50. When the feeding amount of the upstream feeding device is greater than the feeding amount of the downstream sorting device, the controller can control the motor 42 to switch the baffle 41 to the open state. Through the above-mentioned arrangement, when the feeding amount of the upstream feeding device is greater than the feeding amount of the downstream sorting device, the controller can control the motor 42 to switch the baffle 41 to an open state, so that the baffle 41 can avoid the overflow port 3021, and the material can flow out of the overflow device through the overflow groove 33; when the feeding amount of the upstream feeding device is less than or equal to the feeding amount of the downstream sorting device, the controller can control the motor 42 to switch the baffle 41 to a blocked state to prevent part of the material from being unable to flow to the feeding device 20 through the guide groove 32, thereby ensuring the processing efficiency of the overall transportation system. Through the arrangement of the weight sensor, the weighing device 50 and the controller, automatic control of the control device can be realized, which is convenient for real-time control of the material transportation system.

[0040] In other embodiments of the present application, the baffle 41 and the overflow device 30 may also be configured to be plug-in compatible, etc., as long as the overflow port 3021 can be blocked and avoided.

[0041] In some feasible embodiments of the present application, the baffle 41 may also be arranged in the guide groove 32. The area of ​​the guide groove 32 blocked by the baffle 41 is adjusted to adjust the material flow rate through the guide groove 32. When the feed amount of the upstream feeding device is greater than the feed amount of the downstream sorting device, the baffle 41 completely blocks the guide groove 32, and the material can only flow out of the overflow device 30 through the overflow groove 33; when the feed amount of the upstream feeding device is less than or equal to the feed amount of the downstream sorting device, the baffle 41 can partially block or completely avoid the guide groove 32 to allow the material to flow normally.

[0042] In another specific embodiment of the present application, the feeding device 20 includes a feeder and a frequency converter, and the material transportation system also includes a weighing device 50, which is arranged downstream of the feeding device 20 and is used to detect the amount of material entering the downstream sorting device. The frequency converter is electrically connected to the weighing device 50 and the feeder, respectively, and the frequency converter can adjust the working frequency of the feeder through the weight information read by the weighing device 50. Through the above arrangement, the material processing capacity of the downstream sorting system can be adjusted according to the amount of material entering the downstream sorting device, so as to realize flexible production, ensure that the working efficiency of the upstream and downstream of the material transportation system matches, maximize the efficiency in the material transportation process, and improve the overall production efficiency.

[0043] Specifically in the present application, the material transportation system further comprises a transfer device 60, which is arranged corresponding to the overflow channel 302, and the transfer device 60 can transport the material flowing out of the overflow channel 302 to the transfer device 10. Through the above arrangement, all materials can enter the feeding device 20 through the overflow device 30, thereby ensuring that all materials can be sorted and preventing material waste.
