[0002] The herringbone double discharge pipe unloader is an efficient material handling equipment, mainly used in ports, docks, mines, grain and other industries to achieve rapid unloading and transportation of materials. The double discharge pipe design can discharge materials in different directions simultaneously or separately, improving the unloading efficiency. The herringbone structure has a unique shape that helps to evenly distribute materials, prevent blockage, ensure smooth unloading, and can quickly handle a large amount of materials to meet the needs of high-efficiency operations.

[0003] In the prior art, when block materials are unloaded from a discharge pipe block of a herringbone structure onto a conveyor belt, the block materials directly impact the conveyor belt due to their high speed during the descent process, which reduces the stability of the conveyor belt and causes damage to the conveyor belt. In addition, the block materials are easily accumulated on one side of the conveyor belt, resulting in serious unbalanced loading of the materials, which causes the belt to deviate during operation.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] In order to solve the technical problems in the prior art of serious material overloading on the conveyor belt, material spillage and serious belt deviation, the present invention provides an adjusting and centering device, which can stack the materials discharged by the unloader to the middle of the conveyor belt, thereby ensuring the stable operation of the conveyor belt.

It should be noted that the adjustment and centering device is suitable for a discharger with double discharge pipes, and the two pairs of discharge pipes are in a herringbone shape. When the bulk material is discharged from the discharge pipe, the bulk material has a faster speed and directly impacts the conveyor belt, which is easy to cause damage to the conveyor belt and easily cause one side of the conveyor belt to be seriously unloaded; the feed port of the cover body 1 is connected to a discharge pipe of the discharger.

[0020] In actual use, the outlet at the bottom of the discharge channel 2a is arranged opposite to the middle of the conveyor belt A, and the block materials in the discharger are discharged from the discharge pipe. The discharged materials first fall onto the buffer 22. The collision between the materials and the buffer 22 can reduce the descending speed of the materials; then, the block materials slide from the buffer 22 to the two guide members 21, and the block materials can slide from the guide members 21 to the bottom of the discharge channel 2a, and be discharged from the outlet of the discharge channel 2a to the conveyor belt A.

[0021] In this specific embodiment, the cover body 1 is welded by multiple steel plates, and there is an installation cavity inside the cover body 1. The cover body 1 includes a top plate and two vertical plates. The top plate is connected between the two vertical plates, and a feed port is opened on the top plate, wherein the conveyor belt passes through the cover body 1.

[0022] It should be noted that the material guide member 21 is not limited to a specific structure, as long as it can guide the material to the middle of the conveyor belt, and no other limitation is made here.

[0023] In one embodiment, the material guide member 21 includes a baffle 211, one side of the baffle 211 is fixedly connected to the inner wall of the cover body 1, the material discharge channel 2a is formed between the two baffles 211, and the other sides of the two baffles 211 extend to the bottom of the buffer member 22.

[0027] It should be noted that the protrusion is a semicircular protrusion. In other embodiments, the bottom plate 222 may be an arc-shaped bottom plate or an angle-shaped bottom plate. When the bottom plate 222 is an angle-shaped bottom plate, the angle of the angle-shaped bottom plate is 150°.

[0028] On the basis of the above scheme, in order to reduce the impact of block materials on the bottom plate 222, the two side plates 221 are movably connected to the inner top wall of the cover body 1 via multiple elastic members 223. In one embodiment, the side plates 221 are integrally formed with flanges, and the flanges are provided with multiple through holes at intervals. The elastic member 223 includes a guide rod and a spring.

[0030] It should be noted that the pushing mechanism 3 is not limited to a specific structure, as long as it can push the raised portion on the conveyor belt to the opposite sides of the conveyor belt, and no further details are given here.

[0031] In one embodiment, the pushing mechanism 3 is a horizontal plate. By arranging the horizontal plate in the cover body and straddling the top of the conveyor belt, when the protruding part of the block material blocks the horizontal plate, the horizontal plate can push the protruding part of the block material to the opposite sides of the conveyor belt.

[0034] On the basis of the above scheme, the pushing mechanism 3 also includes a baffle 35, which is fixedly connected to the movable end of the lifting member 31 and is located on one side of the two spiral blades 33. An opening is formed on the other side of the baffle 35 and the two spiral blades 33, and the opening faces the centering mechanism 2; when the conveyor belt transports bulk materials, the baffle 35 can block the protruding part of the bulk materials, making it convenient for the spiral blades 33 to push the materials to the opposite sides of the conveyor belt.

[0035] In order to better understand the present invention, the following Figures 1 to 7 The technical solution of the present invention is described in detail: The block materials in the discharger are discharged from the discharge pipe, and the discharged materials first fall onto the bottom plate 222. The collision between the materials and the bottom plate 222 can reduce the descending speed of the materials. Then, the block materials slide from the bottom plate 222 to the two baffles 211, and the block materials can slide from the two baffles 211 to the bottom of the discharge channel 2a, and be discharged from the outlet of the discharge channel 2a to the conveyor belt A; the driving member 34 drives the rotating shaft 32 to rotate, driving the spiral blades 33 to rotate in the opposite direction, and the two spiral blades 33 can push the protruding parts of the block materials to the opposite sides of the conveyor belt, ensuring that the block materials can spread the entire conveyor belt and avoid material accumulation in the middle of the conveyor.
