Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application. Embodiment 1

[0027] As Figures 1 to 7 shown:

[0028] In the prior art in this embodiment, the following problems exist: the inventor finds that the following defects exist in the prior art: 1. The buffer layer of the device is prone to damage and aging after long-term use, resulting in reduced buffering effect. At the same time, the buffer layer of the device is arranged inside the ore bucket, and is not easy to replace; 2. During the discharging process of the ore bucket, the ore may accumulate inside the ore bucket, causing blockage. At this time, workers need to manually remove the blockage, which is time-consuming and labor-intensive; 3. The ore enters the ore bucket and falls by relying on its own gravity and kinetic energy of collision with the ore bucket, and the discharging efficiency is low;

[0029] Therefore, the inventor provides a mine discharge hopper, which comprises a collecting hopper 1, a shell 2, an auxiliary device, and a controller 3. The collecting hopper 1 is arranged above the shell 2. The auxiliary device is arranged on the inner side and the right side of the shell 2. The controller 3 is arranged on the front side of the shell 2, and the controller 3 is in electrical signal connection with the auxiliary device. The auxiliary device further comprises a buffer conveying device and an anti-blocking device. The buffer conveying device is arranged on the right side surface of the shell 2, and the anti-blocking device is arranged inside the shell 2.

[0030] With the above scheme, the ore of the upstream device enters the funnel housing 2 from the collecting hopper 1, and the ore falls on the buffer conveying device under the buffering and blocking action of the anti-blocking device. After further buffering, the ore is conveyed to the left by the conveying belt 9 to the downstream device. When the ore is accumulated in the funnel, the anti-blocking device is started by the controller 3 to loosen the blocked ore pile, and the buffer conveying device timely sends out the blocked ore. The buffer conveying device can observe the wear condition at the right side of the housing 2 during operation, and can be replaced in time when the wear is excessive, thereby ensuring the buffering and conveying effect. Example 2

[0031] As shown in Figures 1 to 7

[0032] Further, the buffer conveying device further comprises a mounting frame 4, a driving motor 5, a driving shaft 6, a transmission shaft 7, a fixed shaft 8, and a conveying belt 9. The mounting frame 4 is arranged at the front side and the rear side of the housing 2, respectively. The driving motor 5 is arranged at the lower right side of the front side of the mounting frame 4. The driving shaft 6 is arranged at the output end of the driving motor 5. The transmission shaft 7 is arranged at the upper end and the lower left end of the mounting frame 4, respectively. The fixed shaft 8 is rotatably arranged at the inner side of the middle part of the housing 2. The conveying belt 9 is connected to the driving shaft 6, the transmission shaft 7, and the fixed shaft 8.

[0033] Further, the mounting frame 4 is provided with a replacement opening 10 at the right side.

[0034] Further, the surface of the conveying belt 9 is provided with a flexible buffer shell a (not shown in the figure).

[0035] Further, the conveying belt 9 is provided with an interface 11 connecting the two ends of the conveying belt 9 at both sides.

[0036] When the ore of the upstream device enters the funnel device from the collecting hopper 1, the ore is preliminarily buffered by the anti-blocking device and falls on the conveying belt 9. The flexible buffer shell a on the surface of the conveying belt 9 continues to dissipate the kinetic energy of the ore, and the driving motor 5 drives the driving shaft 6 to rotate and drive the conveying belt 9 to convey the ore on the transmission shaft 7. The fixed shaft 8 divides the conveying belt 9 in the housing 2 into two inclined surfaces, so that the space for accommodating the ore in the housing 2 is increased. In this way, the input ore can be output to the downstream device in time when the funnel conveys the ore, thereby improving the ore discharging and conveying efficiency.

[0037] ​In the use of the device, workers can observe the exposed conveyor belt 9 on the right side of the shell 2, and judge whether the conveyor belt 9 needs to be replaced according to the wear degree of the flexible buffer shell a on the surface of the conveyor belt 9. When the conveyor belt 9 needs to be replaced, the interface 11 of the conveyor belt 9 is controlled by the controller 3 to run to the replacement port 10, the interface 11 is opened to remove the conveyor belt 9, and the interface 11 can be connected by thread connection, full buckle connection, and half buckle connection according to the actual use. After that, the new conveyor belt 9 is replaced. Such not only can more easily observe the wear of the buffer shell a on the conveyor belt 9, ensure that the buffer conveying effect of the device can be replaced in time, and at the same time, the conveyor belt 9 can be driven to the outside of the device, which is convenient for replacement, ensures the buffer effect of the device, and improves the efficiency of replacing the buffer shell a. Embodiment 3

[0038] As Figures 1 to 7 shown:

[0039] Further, the anti-blocking device further comprises an electric actuator 12, a rotating shaft 13, an anti-blocking block 14, and a buffer shell b 15. The rotating shaft 13 is rotatably arranged on the inner side of the shell 2, the output end of the electric actuator 12 is connected to the front side of the rotating shaft 13, the anti-blocking blocks 14 are arranged on the outer side of the rotating shaft 13 respectively, and the buffer shell b 15 is arranged on the surface of the rotating shaft 13 between the anti-blocking blocks 14.

[0040] Further, the top end of the anti-blocking block 14 is provided with a tooth block 16.

[0041] When the device is normally running and no ore blocking occurs, the anti-blocking block 14 can serve as a buffer when the ore falls. The ore falling on the surface of the rotating shaft 13 can also be buffered by the buffer shell b 15 to buffer part of kinetic energy. When the amount of ore transported by the upstream equipment is too large, causing the ore to accumulate and block the device, workers can control the electric actuator 12 through the controller 3. The electric actuator 12 can be a full-stroke or partial-stroke actuator. The electric actuator 12 drives the anti-blocking block 14 on the rotating shaft 13 to rotate to loosen the blocked ore pile. The tooth block 16 at the top end of the anti-blocking block 14 can be inserted into the gap of the ore pile when the ore is blocked, achieving better results when the anti-blocking block 14 is shaken. At the same time, in cooperation with the buffer conveying device, the loosened ore is timely sent out of the funnel, achieving the effect of automatic cleaning of the blockage, saving the additional cost of manual cleaning, improving the work efficiency, and improving the reliability of the device.

[0042] In summary, the device adopts a buffer conveying device, which provides buffer for the falling ore while conveying the ore out through the conveying belt 9, part of the conveying belt 9 is exposed outside the device to facilitate workers to observe the wear condition, and a convenient replacement mechanism is arranged to ensure the buffer effect while improving the replacement efficiency; the ore is conveyed through the conveying belt 9, thereby improving the conveying efficiency of the device; the anti-blocking device is arranged to automatically dredge the blocked ore in cooperation with the buffer conveying device, thereby saving the cost of manual dredging, improving the working efficiency, and improving the reliability of the device.

[0043] The working principle of the utility model is as follows:

[0044] The ore of the upstream equipment enters the funnel housing 2 from the collecting hopper 1, and the ore falls onto the buffer conveying device under the buffer blocking action of the anti-blocking device; the flexible buffer shell a on the surface of the conveying belt 9 continues to dissipate the kinetic energy of the ore, and the driving motor 5 drives the driving shaft 6 to rotate to drive the conveying belt 9 to convey the ore on the transmission shaft 7; the fixed shaft 8 divides the conveying belt 9 in the housing 2 into two inclined surfaces, so that the space in the housing 2 for accommodating the ore is increased, thereby the input ore can be output to the downstream equipment in time when the funnel conveys the ore, and the ore discharging conveying efficiency is improved;

[0045] In the use process of the device, workers can observe the conveying belt 9 exposed on the right side of the housing 2, and judge whether the conveying belt 9 needs to be replaced according to the wear degree of the flexible buffer shell a on the surface of the conveying belt 9; when the conveying belt 9 needs to be replaced, the controller 3 controls the interface 11 of the conveying belt 9 to rotate to the replacement opening 10, opens the interface 11 to remove the conveying belt 9, and replaces the new conveying belt 9; this can not only more easily observe the wear condition of the buffer shell a on the conveying belt 9, ensure that the buffer conveying effect of the device can be ensured in time, but also the conveying belt 9 can be transmitted to the outside of the device, facilitating replacement, ensuring the buffer effect of the device while improving the replacement efficiency of the buffer shell a;

[0046] When the amount of ore conveyed by the upstream equipment is too large, causing the ore to accumulate and block the device, workers can control the electric actuator 12 through the controller 3; the electric actuator 12 can adopt a full-stroke and partial-stroke actuator; the electric actuator 12 drives the anti-blocking block 14 on the rotating shaft 13 to rotate, thereby achieving the effect of loosening the blocked ore pile; the tooth block 16 at the top of the anti-blocking block 14 can be inserted into the gap of the ore pile when the ore is blocked, thereby achieving better effect when the anti-blocking block 14 shakes; in cooperation with the buffer conveying device, the loosened ore is sent out of the funnel in time, thereby achieving the effect of automatically cleaning the blockage, saving the additional cost of manual cleaning, improving the working efficiency, and improving the reliability of the device;

[0047] Thus, the working principle of the device is described.
