Description

Technical Field

[0001] This application relates to the technical field of buffer idlers, and particularly to an interleaved arrangement method of buffer idler groups under the feed bin of a feeder. Background Art

[0002] The belt feeder under the bin is a key equipment in the material conveying system, and is widely used in industries such as mines, metallurgy, electric power, building materials, and chemical engineering for the conveying, distribution, and feeding of materials. The feeder usually consists of a feed bin, a vibration device, a conveyor belt, and a buffer idler group, etc., and its function is to evenly convey the materials from the feed bin to the next processing link. The buffer idler group under the feed bin is responsible for supporting the conveyor belt and ensuring the smooth operation of the materials during the conveying process.

[0003] Since all the materials will accumulate on the conveyor belt after falling from the feed bin into the hopper, especially for some ore bins with relatively large bin pressures, the impact and pressure loads on the conveyor belt are relatively large. The conveyor belt is a relatively soft rubber support, and the buffer idler group needs to bear this part of the bin pressure. Due to the gap between the two idlers in the buffer idler group, the conveyor belt will be bent between the two idlers, and the conveyor belt will wear faster along this gap and even be torn. Summary of the Invention

[0004] In order to improve the problem of relatively fast wear of the conveyor belt, this application provides an interleaved arrangement method of buffer idler groups under the feed bin of a feeder.

[0005] An interleaved arrangement method of buffer idler groups under the feed bin of a feeder provided by this application adopts the following technical solutions: An interleaved arrangement method of buffer idler groups under the feed bin of a feeder includes a frame, and a plurality of buffer idler groups are installed on the frame.

Adjacent two buffer idler groups are respectively a first idler group and a second idler group, and the gaps of the intermediate idlers of the first idler group and the gaps of the intermediate idlers of the second idler group are not on the same straight line.

[0006] By adopting the above technical solutions, the lengths of the intermediate idlers in the buffer idler group are adjusted, so that the lengths of the intermediate idlers of adjacent two buffer idler groups are inconsistent, and further the gaps of the intermediate idlers of adjacent two buffer idler groups are not on the same straight line, thereby reducing the possibility of relatively fast wear of the conveyor belt on a certain straight line and improving the service life of the conveyor belt.

[0008] By adopting the above technical solution, when it is necessary to overhaul one of the buffer idler groups, only the support plate of the buffer idler group to be overhauled needs to be pulled outwards, and then the buffer idler group can be overhauled, without having to remove all the buffer idler groups, which makes the overhaul more convenient.

[0009] Preferably, limiting baffles are rotatably installed on the sides of the two connecting plates, the limiting baffles can be attached to the fixing strip, and the limiting baffles are fixedly connected to the connecting plates by bolts.

[0014] By adopting the above technical solution, when it is necessary to replace the intermediate idler, only the bearing plate needs to be rotated upwards, and then the mounting plates at both ends of the intermediate idler to be replaced are moved, so that the ball bearings at the ends of the intermediate idler are separated from the mounting grooves, and the disassembly of the intermediate idler can be completed.

[0015] Preferably, a limiting groove is formed in the bottom surface of the bearing plate. A limiting block is slidably mounted vertically on the bearing plate through the limiting groove.

Detailed implementation manners

[0031] The following further elaborates on this application in conjunction with the attached Figures 1-8 drawings.

[0032] The embodiment of this application discloses an interleaved arrangement method of the buffer idler group under the feeder bin. Referring to Figure 1 and Figure 2 , the interleaved arrangement method of the buffer idler group 2 under the feeder bin includes a vehicle frame 1, on which several buffer idler groups 2 are installed, and the several buffer idler groups 2 are arranged along the length direction of the conveyor belt.

[0033] By adjusting the lengths of the intermediate idlers 4 in the buffer idler group 2, the lengths of the intermediate idlers 4 of two adjacent buffer idler groups 2 are made inconsistent, so that the gaps between the intermediate idlers 4 of two adjacent buffer idler groups 2 are not on the same straight line, thereby reducing the possibility of rapid wear of the conveyor belt on a certain straight line and improving the service life of the conveyor belt.

[0034] Referring to Figure 3 and Figure 4, the frame 1 includes two connecting plates 11. A fixing plate 12 is installed on the top of the connecting plate 11, and a number of fixing grooves 13 are provided on the top surface of the fixing plate 12.

The fixing strip 24 is slidably engaged with the fixing plate 12 along the width direction of the fixing plate 12 through the fixing grooves 13. Limit baffles 14 are rotatably installed on the sides of the two connecting plates 11. The limit baffles 14 can be attached to the fixing strip 24, and the limit baffles 14 are fixedly connected to the connecting plates 11 by bolts.

[0035] When it is necessary to repair one of the buffer idler groups 2, only the bolts need to be removed, the limit baffle 14 is rotated downward, and then the support plate 23 of the buffer idler group 2 to be repaired is pulled outwards, so that the buffer idler group 2 can be repaired, and it is not necessary to remove all the buffer idler groups 2, and the repair is more convenient.

[0036] Refer to Figure 1 and Figure 2 , two inclined support plates 25 are installed on the top surface of the support plate 23, and the side idler 3 is installed between the two inclined support plates 25.

The insertion block 2511 is fixedly connected to the support plate 23 by bolts.

[0037] When it is necessary to replace the side idler 3, the bolts are removed, and then the first inclined plate 251 is disassembled, so that the side idler 3 can be replaced.

[0039] When it is necessary to replace the intermediate idler 4, only the bearing plate 26 needs to be rotated upward, and then the installation plates 41 at both ends of the intermediate idler 4 to be replaced are moved, so that the ball bearings 43 at the ends of the intermediate idler 4 are disengaged from the installation grooves 42, and the disassembly of the intermediate idler 4 can be completed.

[0040] Refer to Figure 7 andFigure 8 The bottom surface of the bearing plate 26 is provided with a limiting groove 51, and the bearing plate 26 is installed with a limiting block 5 by sliding vertically through the limiting groove 51. The top surface of the support plate 23 is provided with a positioning groove 232 for inserting the limiting block 5. A spring 1 52 is fixed to the top surface of the limiting block 5, and the top of the spring 1 52 is fixedly connected to the inner top surface of the limiting groove 51. When the bottom surface of the bearing plate 26 is in contact with the top surface of the support plate 23, the limiting block 5 moves downward under the elastic force of the spring 1 52 and is inserted into the positioning groove 232, thereby limiting the bearing plate 26, so that the bearing plate 26 is not easy to rotate upward.

[0041] Reference Figure 7 and Figure 8 , a pushing groove 61 connected to the limiting groove 51 is provided on the side of the bearing plate 26 away from the rotating rod 27, and a pushing block 6 is installed on the bearing plate 26 to slide along its width direction through the pushing groove 61. A reset block 63 is fixed on the side of the pushing block 6, and a reset groove 62 is provided on the inner wall of the pushing groove 61. The reset block 63 slides and cooperates with the bearing plate 26 along the width direction of the bearing plate 26 through the reset groove 62. A spring 2 64 is fixed on the side of the reset block 63 close to the limiting block 5, and one end of the spring 2 64 away from the reset block 63 is fixedly connected to the inner wall of the reset groove 62. A limiting through groove 53 for passing the pushing block 6 is provided on the side of the limiting block 5, and an inclined surface 1 54 is provided on the inner top surface of the limiting through groove 53. A inclined surface 2 65 for contacting with the inclined surface 1 54 is provided on the side of the pushing block 6 close to the limiting block 5.

[0042] When the middle roller 4 needs to be replaced, the push block 6 is moved toward the direction close to the limit block 5, the inclined surface 1 54 and the inclined surface 2 65 abut against each other, and then the limit block 5 is pushed upward, so that the limit block 5 is disengaged from the positioning groove 232, so that the staff can rotate the supporting plate 26 upward.

[0043] The implementation principle of the staggered arrangement of the buffer roller group 2 under the feeder silo in an embodiment of the present application is: the length of the middle roller 4 in the buffer roller group 2 is adjusted so that the lengths of the middle rollers 4 of two adjacent buffer roller groups 2 are inconsistent, and the gaps between the middle rollers 4 of two adjacent buffer roller groups 2 are not on the same straight line, thereby reducing the possibility of rapid wear of the conveyor belt on a certain straight line and increasing the service life of the conveyor belt.
