Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of belt conveyors, in particular to a horizontal turning device of a belt conveyor. BACKGROUND

[0002] In coal mining and coal block transfer processing, a large amount of coal blocks are transported by a conveying belt. In the transportation process, when the angle of horizontal turning is small, the conveying machine can be increased and adjusted to realize natural turning. When the angle of turning is large, the conveying belt cannot be turned naturally, and the conveying belt is damaged seriously.

[0003] In the large-angle turning, the prior art divides the conveying belt into two, and the two conveying belts have an included angle to complete the turning. The coal blocks directly fall from one conveying belt to another conveying belt to realize reverse transportation and complete horizontal turning. However, the coal blocks have the characteristics of large quantity and high speed during transportation. The two conveying belts are staggered. When the coal blocks fly out from the end of the first conveying belt to the other conveying belt, the impact force is approximately perpendicular to the conveying belt, which has a large impact on the conveying belt, and the impact force easily causes the conveying belt to deviate or be damaged, thereby reducing the service life.

[0004] In the prior art, the problem of easy deviation or damage of the conveying belt during the reverse transportation of the coal blocks needs to be solved. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a horizontal turning device of a belt conveyor, which solves the problem of easy deviation or damage of the conveying belt during the reverse transportation of the coal blocks in the prior art.

[0006] The technical scheme adopted by the present application is to provide a horizontal turning device of a belt conveyor for transferring coal blocks on a first conveying belt to a second conveying belt, characterized in that it comprises: a support located between the first conveying belt and the second conveying belt, the support having a support disc at the upper end; a turntable rotatably arranged on the support disc, the end of the first conveying belt being located above the turntable, and the end of the second conveying belt being located below the turntable; a fence surrounding the support disc and having an inlet and an outlet, the inlet being opposite to the end of the first conveying belt, and the outlet being opposite to the end of the second conveying belt; The coal blocks move from the end of the first conveying belt through the inlet to the turntable, and then move from the outlet to the end of the second conveying belt after following the rotation of the turntable.

[0007] Further optimization of the technical scheme is that the direction in which the coal blocks move from the outlet is parallel to the transportation direction of the second conveying belt.

[0008] Further optimization of the technical solution, the support disc is inclined, and the outlet is located at a lower side of the support disc.

[0009] Further optimization of the technical solution, the support disc is inclined, and the outlet is located at a lower side of the support disc. A material pushing plate is arranged at the center of the rotating disc shaft.

[0010] Further optimization of the technical solution, the enclosure includes a plurality of partitions, and the lower part of each partition is provided with a sliding seat which is slidably arranged on the periphery of the support disc.

[0011] Further optimization of the technical solution, the partition is located above the rotating disc.

[0012] Further optimization of the technical solution, the sliding seat is fixed on the support disc by bolts.

[0013] Further optimization of the technical solution, the support disc is inclined, and the outlet is located at a lower side of the support disc. A material pushing plate is arranged on the support disc and below the outlet, and the material pushing plate extends above the second conveying belt.

[0014] The present application has the following advantages: 1. When the rotating disc rotates, it receives the coal blocks flying out from the end of the first conveying belt, converts the linear motion of the coal blocks into circular motion, reduces the impact force of the coal blocks, and then the coal blocks are roughly parallel to the conveying direction of the second conveying belt from the outlet, so that the offset impact on the second conveying belt is reduced, and the offset and damage of the second conveying belt are reduced.

[0015] 2. The enclosure can prevent the coal blocks from flying out at will on the rotating disc, limit the movement path of the coal blocks, and finally make the coal blocks fall onto the second conveying belt.

[0016] 3. Compared with the conveying belt, the rotating disc has stronger impact resistance, and the direct impact of the coal blocks can be reduced by rotating, so that the service life of the rotating disc is long. BRIEF DESCRIPTION OF DRAWINGS

[0022] like Figures 1-6 As shown, a belt conveyor horizontal turning device is used to transfer coal blocks from a first conveyor belt 101 to a second conveyor belt 102. The device comprises: a support 2 positioned between the first conveyor belt 101 and the second conveyor belt 102, with a support plate 201 at the upper end of the support 2; a turntable 3 rotatably mounted on the support plate 201, with the end of the first conveyor belt 101 positioned above the turntable 3 and the end of the second conveyor belt 102 positioned below the turntable 3; and a barrier 4 mounted on the support plate 201, having an inlet 401 and an outlet 402, with the inlet 401 facing the end of the first conveyor belt 101 and the outlet 402 facing the end of the second conveyor belt 102. Coal blocks move from the end of the first conveyor belt 101 through the inlet 401 to the turntable 3, and then, following the rotation of the turntable 3, move from the outlet 402 to the end of the second conveyor belt 102. The direction in which the coal blocks move from the outlet 402 is parallel to the conveying direction of the second conveyor belt 102.

[0023] In use, there is an included angle between the first conveying belt 101 and the second conveying belt 102, that is, the angle of the turn, the conveying direction of the first conveying belt 101, that is, the direction of the coal blocks flying out of the end of the first conveying belt 101, points to the outlet 402, and the flying direction is preferably not directed to the axis of the turntable 3. The coal blocks fall on the turntable 3 with an initial speed and direction, follow the rotation of the turntable 3, can reduce the direct impact of the coal blocks, convert the linear motion into the circumferential motion, and after turning to the outlet 402, are thrown out from the outlet 402 to the second conveying belt 102 under the action of the centrifugal force, the throwing direction is substantially parallel to the conveying direction of the second conveying belt 102, and the unilateral deviation impact on the second conveying belt 102 is weakened. The coal blocks complete the turning on the turntable 3.

[0024] The turntable 3 itself has strong impact resistance, the butt joint angle of the first conveying belt 101 and the turntable 3 is relatively loose, the coal blocks are not directly directed to the axis, the linear motion can be converted into the circumferential motion, and the damage caused by the direct impact is reduced. The main direction of the large amount of coal blocks flying out of the outlet 402 is parallel to the conveying direction of the second conveying belt 102, which can protect the second conveying belt 102. Therefore, the coal blocks can complete the turning on the turntable 3, can meet the use of different included angles between the first conveying belt 101 and the second conveying belt 102, complete the horizontal turning, and have good applicability.

[0025] The rotation of the turntable 3 can be driven by a motor, which is a conventional technology, and the motor and the transmission structure are not shown in the drawing for the sake of simplicity of the drawing, and can be realized by those skilled in the art. The support disc 201 supports the turntable 3, improves the stability and impact resistance of the turntable 3.

[0026] The first conveying belt 101 and the second conveying belt 102 can be a planar conveying belt or a concave conveying belt, and only the position is shown in the drawing for the sake of simplicity of the drawing.

[0027] Further, the support disc 201 is inclinedly arranged, and the outlet 402 is located at the lower side of the support disc 201.

[0028] In use, the support disc 201 is inclinedly arranged, the turntable 3 adheres to the support disc 201 and is also in an inclined state, the turntable 3 has high and low positions, the coal blocks are more easily moved to the lower side when following the rotation of the turntable 3 under the guidance of gravity, and the outlet 402 is arranged at the lower side, so that the coal blocks are more easily thrown out from the outlet 402. The outlet 402 is located at the lowest position to ensure that the coal blocks are smoothly thrown out, and the inlet 401 does not need to be necessarily located at the highest position.

[0029] The support 2 can have multiple legs, by setting different heights of the legs, the support disc 201 can be inclined. The end of the first conveying belt 101 is above the rotating disc 3, and is also above the second conveying belt 102, which can be achieved by inclining the end of the first conveying belt 101 upward, without the whole first conveying belt 101 being in a high position.

[0030] Further, the device further comprises a stirring plate 5 arranged at the center of the rotating disc 3.

[0031] In use, the stirring plate 5 arranged at the center of the rotating disc 3 is beneficial to throw out the coal blocks close to the center of the rotating disc 3 during rotation, so that the coal blocks are discharged from the outlet 402. The stirring plate 5 can be a cuboid structure.

[0032] Further, the enclosure 4 comprises a plurality of partitions 403, and the lower part of each partition 403 is provided with a sliding seat 404 which is slidably arranged on the periphery of the support disc 201.

[0033] The sliding seat 404 is fixed to the support disc 201 by bolts 405.

[0034] In use, the enclosure 4 is composed of a plurality of partitions 403 arranged in a ring shape, and the position of each partition 403 can be adjusted by sliding on the support disc 201, so as to adjust the positions of the inlet 401 and the outlet 402, thereby matching the different positions of the first conveying belt 101 and the second conveying belt 102. By arranging different numbers of partitions 403 and adjusting the angular interval between the partitions 403, the size of the inlet 401 and the outlet 402 can be changed. When a single partition 403 is damaged, it can be replaced individually, which is more convenient for maintenance and replacement, and the cost is low.

[0035] The sliding seat 404 can be a semi-enclosed structure which is slidably arranged on the periphery of the support disc 201, and the sliding seat 404 can be tightly fixed to the support disc 201 by the bolts 405. The partition 403 is located at the upper end of the sliding seat 404.

[0036] Further, the partition 403 is located above the rotating disc 3.

[0037] In use, the partition 403 is located above the rotating disc 3, and part of the rotating disc 3 is located outside the partition 403. When the coal blocks fall onto the rotating disc 3 inside the partition 403 and follow the rotation, the lower side and the outside of the rotating disc 3 are exposed when the rotating disc 3 rotates to the vicinity of the outlet 402, so that the coal blocks are deviated and slide to the outlet 402 under the action of centrifugal force and gravity component force, and the coal blocks can be thrown out more stably.

[0038] Further, the device further comprises a gathering plate 6 arranged on the support disc 201 and located below the outlet 402, and the gathering plate 6 extends above the second conveying belt 102.

[0039] In use, the direction of the coal blocks flying out from the outlet 402 can be measured and calculated through experiment simulation, and the main flying direction of a large number of coal blocks can be used as a reference, that is, the direction is parallel or approximately parallel to the conveying direction of the second conveying belt 102, and a small part of the coal blocks flying out in a large angle deviation or with a small flying distance can be collected and received by the collecting plate 6, so as to ensure that the coal blocks finally fall on the second conveying belt 102. The collecting plate 6 does not affect the concentrated flying of the coal blocks from the outlet 402, and the coal blocks received on the collecting plate 6 fall on the second conveying belt 102 with small impact force, so it is not necessary to limit that the collecting plate 6 is parallel to the conveying direction of the second conveying belt 102, and in the drawing, only the position of the collecting plate 6 is shown, and the angle is not limited.

[0040] The collecting plate 6 can also be arranged in the structure of the sliding seat 404, and is slidably arranged on the supporting disc 201, so as to facilitate the position adjustment of the collecting plate 6 and improve the applicability.

[0041] It can be understood that the present application is described through some embodiments, and those skilled in the art know that various changes or equivalent replacements can be made to the features and embodiments without departing from the spirit and scope of the present application. In addition, the features and embodiments can be modified to adapt to specific conditions and materials under the guidance of the present application without departing from the spirit and scope of the present application.
