Description

Technical Field

[0001] This utility model relates to the technical field of underground ore extraction equipment, and in particular to a buffer device for the impact surface of the feed inlet. Background Technology

[0002] Normally, underground ore is transported to a weighing hopper via a belt conveyor, and then lifted to the shaft opening via a skip. An underground weighing hopper typically includes a fixed hopper frame, a chute, and a baffle adjustment system. The baffle controls the ore flow rate via a linkage mechanism or electric device. Each time ore is discharged, the belt conveyor transports the ore into the weighing hopper. However, because the ore has an initial velocity when it leaves the belt, it falls in a parabolic trajectory. Upon entering the hopper, it primarily impacts the inner front of the weighing hopper. Over time, this can cause the inner lining of the weighing hopper to detach, and if it is lifted to the upper belt, it can easily tear the belt, affecting the equipment's service life. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the inner lining of the existing metering hopper is easily detached due to the impact of ore and has a short service life. It provides a buffer device for the impact surface of the discharge port, which can improve the buffering force, reduce the direct impact on the metering hopper lining, reduce the risk of the inner lining of the metering hopper detaching, and increase the service life of the impact surface lining.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A feed inlet impact surface buffer device includes an L-shaped wear-resistant liner plate installed inside the metering hopper. The L-shaped wear-resistant liner plate is positioned directly opposite the ore impact surface so that when the ore falls from the belt conveyor, it first impacts the L-shaped wear-resistant liner plate, thereby effectively protecting the inner side of the metering hopper.

[0006] The L-shaped wear-resistant liner is connected to the inner side of the metering hopper by a snap-fit ​​fixing mechanism. The L-shaped wear-resistant liner is also provided with buffer rubber dots and buffer rubber surfaces. The outer end face of the L-shaped wear-resistant liner is also connected with an auxiliary sliding soft plate to assist the ore impacting the liner to fall into the metering hopper.

[0007] Furthermore, the buckle fixing mechanism includes a buckle block and a buckle groove that fit together. The buckle block has an inverted L-shaped structure, and the buckle groove is located in a buckle groove seat. The buckle groove seat has an L-shaped structure. When the buckle block and the buckle groove seat are engaged, the buckle block is perfectly embedded in the buckle groove.

[0008] Furthermore, the L-shaped wear-resistant liner includes a vertical plate and a horizontal plate, with a locking block fixed to the back of the vertical plate and a locking slot fixed to the inner side of the measuring hopper.

[0009] Furthermore, the vertical plate has a matrix of buffer adhesive dots arranged on the side facing the belt conveyor.

[0010] Furthermore, the upper surface of the horizontal plate is set as an inclined plane, and the end of it closer to the vertical plate is higher than the end farther from the vertical plate. The angle between the inclined plane and the horizontal direction is 10°~15°.

[0011] Furthermore, a layer of buffer rubber is laid on the inclined surface, with the thickness of the buffer rubber being set to 5~15mm.

[0012] Furthermore, one side of the auxiliary sliding soft plate is connected to the outer end of the horizontal plate, and its thickness gradually decreases from the side closer to the horizontal plate to the side farther away from the horizontal plate.

[0013] Furthermore, a triangular support frame is provided between the bottom surface of the horizontal plate and the inner side of the metering hopper to improve the impact resistance of the L-shaped wear-resistant liner.

[0014] In the technical solution of this utility model, by adding an L-shaped wear-resistant liner to the impact surface inside the measuring hopper, the buffering force is increased, the direct impact on the measuring hopper liner is reduced, the risk of the inner liner falling off is reduced, and the L-shaped wear-resistant liner is easy to replace, which improves work efficiency and extends the service life of the measuring hopper.

[0017] To make this utility model clearer, the following description, in conjunction with the accompanying drawings, further illustrates a feed inlet impact surface buffer device of this utility model. The specific embodiments described herein are for illustrative purposes only and are not intended to limit this utility model.

[0018] See Figure 1 A material discharge port impact surface buffer device, characterized in that:

[0019] See Figure 1 and Figure 2 It includes an L-shaped wear-resistant liner 2 installed inside the metering hopper 1. The L-shaped wear-resistant liner 2 is positioned facing the impact surface of the ore 8. A snap-fit ​​fixing mechanism 3 is connected between the L-shaped wear-resistant liner 2 and the inner side of the metering hopper 1.

[0020] The buckle fixing mechanism 3 includes a buckle block 31 and a buckle groove 32a that fit together. The buckle block 31 is an inverted L-shaped structure. The buckle groove 32a is located in the buckle groove seat 32. The buckle groove seat 32 is an L-shaped structure. When the buckle block 31 and the buckle groove seat 32 are engaged, the buckle block 31 is perfectly embedded in the buckle groove 32a. The L-shaped wear-resistant liner 2 includes a vertical plate 21 and a horizontal plate 22. The buckle block 31 is fixed to the back of the vertical plate 21, and the buckle groove seat 32 is fixed to the inner side of the measuring hopper 1.

[0021] The vertical plate 21 has a matrix of buffer rubber dots 4 on the side facing the belt conveyor 9;

[0022] The upper surface of the horizontal plate 22 is set as an inclined surface 22a, and the end of it that is closer to the vertical plate 21 is higher than the end that is farther away from the vertical plate 21. The angle between the inclined surface 22a and the horizontal direction is 12°. A layer of buffer rubber surface 5 is laid on the inclined surface 22a, and the thickness of the buffer rubber surface 5 is set to 10mm.

[0023] An auxiliary sliding plate 6 is also connected to the outer end face of the L-shaped wear-resistant liner 2. One side of the auxiliary sliding plate 6 is connected to the horizontal plate 22, and its thickness gradually decreases from the side closer to the horizontal plate 22 to the side farther away from the horizontal plate 22.

[0024] In this embodiment, a triangular support frame 7 is provided between the bottom surface of the horizontal plate 22 and the inner side surface of the metering hopper 1 to improve the impact resistance of the L-shaped wear-resistant liner.

[0025] The device of this invention improves the service life of the inner liner of the impact surface. By adding an L-shaped wear-resistant liner, the falling ore is buffered. The ore falls into the metering hopper below through the L-shaped wear-resistant liner, which greatly reduces the impact force of the ore on the metering hopper and ensures the normal use of the metering hopper.

[0026] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
