Description

Technical Field

[0001] The utility model relates to the technical field of buffer chutes, in particular to a mine hopper blanking buffer chute. Background Art

[0002] Mines include coal mines, metal mines, non-metallic mines, building materials mines and chemical mines. In the mining production process, mining operations consume the most manpower and material resources, occupy the most funds, and are also the production link with the greatest potential for reducing mining costs. During mining operations, a mine hopper drop buffer chute is usually required to carry out directional transportation of mined minerals from the mine to the outside. When some existing mine hopper drop buffer chutes transfer the ore to the conveyor, multiple staggered inclined plates can buffer and block the ore during movement and then fall directly onto the conveyor surface. When the ore is discharged, it cannot be completely unloaded and buffered, which can easily cause damage to the conveyor belt. Utility Model Content

[0003] In view of this, the utility model provides a mine hopper drop buffer chute, which can not only block and buffer the ore, ensuring the buffering effect of the ore, but also prevent the ore from falling directly onto the conveyor belt, which is beneficial to the service life of the conveyor belt.

[0004] In order to solve the above technical problems, the utility model provides a mine hopper material drop buffer chute, comprising a conveyor, a mineral material chute is arranged above the conveyor, and a buffer assembly is arranged in the mineral material chute;

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0022] According to one embodiment of the present invention, Figure 1 、 Figure 2 and Figure 4 As shown: This embodiment provides a mine hopper material drop buffer chute, including a conveyor 100, a mineral chute 200 is arranged above the conveyor 100, and a buffer assembly 300 is arranged in the mineral chute 200;

[0023] The buffer assembly 300 includes a connecting rod 301 rotatably connected to the right end of the mineral chute 200, and a buffer plate 302 is provided on the connecting rod 301. Two telescopic springs 303 connected to the buffer plate 302 are symmetrically provided at the right end of the mineral chute 200. A blanking plate 304 and a connecting plate 305 are respectively provided at the bottom of the mineral chute 200. Two return springs 306 are symmetrically provided on the side of the connecting plate 305. A baffle 307 is provided on the two return springs 306. Two support plates 400 are symmetrically provided at the bottom of the mineral chute 200. A slide groove 308 is provided between the two support plates 400. A sliding block 309 is slidably connected in the slide groove 308. The sliding blocks 309 are connected to the baffle 307. A guide plate 310 is provided at the bottom end of the connecting plate 305. The mineral material moved to the right side of the mineral chute 200 will contact the surface of the buffer plate 302. At this time, the telescopic spring 303 will be subjected to force due to the inertia of the mineral material. Contraction can achieve a buffering effect on the ore. Under the rotation relationship of the rotating rod, the buffer plate 302 will move, and the ore will contact the baffle 307. At this time, the return spring 306 will be forced to contract, and the baffle 307 drives the sliding block 309 to slide in the chute 308, ensuring the support stability of the baffle 307. The blocked ore can fall gently on the guide plate 310, realizing the buffering falling operation of the ore. The blanking plate 304 is inclined toward the connecting plate 305. The guide plate 310 is tilted downward from left to right and can guide the ore to the surface of the conveyor 100. A discharge port 600 is provided at the bottom of the ore chute 200. The buffer plate 302 is located at the discharge port 600. The baffle 307 is located between the blanking plate 304 and the connecting plate 305. The ore falls onto the blanking plate 304 through the discharge port 600 and moves to the left. The guide plate 310 is arranged parallel to the upper side of the conveyor 100.

[0024] According to another embodiment of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, a fixed seat 500 is provided at the bottom of the support plate 400, and the fixed seat 500 is connected to the conveyor 100 through a screw. The mineral chute 200 is tilted downward from left to right. When the mineral is transferred, the staff can connect the upper side of the mineral chute 200 with the discharge port 600 of the hopper. The mineral discharged from the hopper will continue to move to the right through the tilting effect of the mineral chute 200. A plurality of buffer bars 700 are evenly arranged on the surface of the mineral chute 200. During the movement, the buffer bars 700 can play a certain resistance role to buffer the falling speed of the mineral.

[0025] The use method of the present invention is as follows: when carrying out the ore transfer operation, the staff can connect the upper side of the ore chute 200 with the discharge port 600 of the hopper. The ore discharged from the hopper will continuously move to the right through the tilting effect of the ore chute 200. During the movement, the buffer bar 700 can play a certain role in resisting and buffering the falling speed of the ore. The ore moved to the right side of the ore chute 200 will contact the surface of the buffer plate 302. At this time, due to the inertia of the ore, the telescopic spring 303 will be forced to shrink, which can achieve the buffering effect on the ore. Under the rotation relationship of the rotating rod, the buffer plate 302 will move. When the discharge port 600 is opened, the mineral material falls through the discharge port 600 onto the blanking plate 304 and moves to the left. The mineral material will contact the baffle 307. At this time, the return spring 306 will be forced to shrink, and the baffle 307 drives the sliding block 309 to slide in the slide groove 308, ensuring the stable support of the baffle 307. The blocked mineral material can fall gently on the guide plate 310 and finally be guided to the surface of the conveyor 100, realizing the buffering falling operation of the mineral material. The utility model can not only block and buffer the mineral material, ensuring the buffering effect of the mineral material, but also prevent the mineral material from falling directly on the conveyor belt, which is beneficial to the service life of the conveyor belt.

[0026] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
