[0001] The present invention relates to the technical field of conveying buffering, and particularly relates to a buffer bed for a belt conveyor. Background Art

[0002] The buffer bed of a belt conveyor is an important auxiliary device. The buffer bed is installed below the material loading point (such as the feeding port), bears the impact force when the material falls, and is mainly used to reduce the impact of the material on the conveyor belt, protect the conveyor belt and idlers, thereby improving the equipment life and optimizing the operation efficiency; the existing buffer bed mainly consists of a support frame, a support frame and buffer rubber strips. The buffer rubber strips are fixed to the support frame by bolts, and the support frame is then fixed to the support frame by bolts. fixed to the support frame.

[0003] However, the following problems exist in the assembly and use of the buffer bed at present: it is necessary to fix the buffer rubber strip and the support frame with multiple bolts. During installation, it is necessary to repeatedly align, pre-tighten the bolts, and finally tighten them. The overall operation is cumbersome and time-consuming. At the same time, it is difficult to ensure that the tightening firmness of the bolts at the corresponding positions is consistent, and a large number of bolts need to be disassembled when maintaining or replacing the rubber strips, which is time-consuming and laborious; secondly, the existing buffer bed only buffers through the buffer rubber strips, and the overall buffer effect needs to be improved.

[0004] Therefore, the problems of cumbersome disassembly and assembly of the buffer bed, inconsistent tightening firmness of bolts, and poor buffer effect are technical problems that need to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the above problems, an embodiment of the present invention provides a buffer bed for a belt conveyor to solve the above-mentioned technical problems.

[0006] To achieve the above object, an embodiment of the present invention provides the following technical solution: A buffer bed for a belt conveyor includes a plurality of support components distributed front and back. Three fixing plates arranged from left to right are commonly arranged on the support components. The middle fixing plate is horizontally arranged on the support components, and the fixing plates on both sides are obliquely arranged on the support components in an inverted V shape.

[0007] The buffer bed further includes a buffer mechanism and a limiting part. The buffer mechanism includes a support frame arranged in a concave structure and evenly arranged from left to right at the upper end of the fixing plate. T-shaped blocks fixedly installed at the lower end of the support frame are arranged between adjacent support components. Waist-shaped grooves slidably matched with the T-shaped blocks are opened on the fixing plates. A buffer rubber strip is slidably installed in the support frame. A buffer spring corresponding to the T-shaped block is detachably installed between the buffer rubber strip and the support frame. The buffer rubber strip and the buffer spring form an elastic superposition structure.

[0008] The limiting part includes a locking member for fixing the buffer spring and a connecting block arranged on the buffer spring and sliding through the T-shaped block. A positioning plate corresponding to the fixing plate one by one is arranged between adjacent two support components. A limiting post is slidably installed on the T-shaped block. During the forward movement of the support frame driving the T-shaped block, the front and rear ends of the limiting post respectively penetrate through the positioning plate and the connecting block, and the support frame is preliminarily fixed on the fixing plate; a locking part for locking the moved support frame is arranged on the support component.

[0009] As a preferred solution, the limiting part includes a disc. Discs are fixedly installed at both the upper and lower ends of the buffer spring. The lower end of the lower disc is fixedly connected to the upper end of the connecting block, and the upper disc is detachably installed on the buffer rubber strip.

[0010] As a preferred solution, the support component includes two channel steels that are symmetric front and back and have openings facing away from each other. A bottom plate is fixedly installed at the upper ends of the two channel steels. A rectangular groove communicating with the gap between the two channel steels is opened in the middle of the bottom plate. Two symmetrically arranged left and right support plates are rotatably installed between the two channel steels through a shaft column. The upper end surface of the support plate is an inclined surface that slopes downward from top to bottom towards the middle of the bottom plate. The inclined surfaces of the support plates arranged front and back and on the same side are fixedly connected to the corresponding fixing plate together.

[0011] As a preferred solution, the support component further includes an L-shaped support fixedly installed in the middle of the bottom plate. The upper ends of the vertical sections of the L-shaped supports of multiple support components are fixedly connected to the middle fixing plate.

[0012] As a preferred solution, an adjusting member for adjusting the angle of the support plate is jointly arranged on the support plate and the bottom plate; the adjusting member includes an arc-shaped groove. An arc-shaped groove concentric with the corresponding shaft column is opened on the support plate. A support seat is fixedly installed on the bottom plate. A bolt is threadedly connected to the support seat. The bolt slidably penetrates through the arc-shaped groove and then a first nut is installed. The support plate is fixed on the support seat through the cooperation of the bolt and the first nut.

[0013] As a preferred solution, the locking part includes a pushing plate. A pushing plate corresponding to the fixing plate one by one and located at the rear side of the corresponding T-shaped block is arranged between adjacent two support components. Two guiding shafts that slidably penetrate through the corresponding positioning plate and the support plate are fixedly installed at the front ends of the left and right two pushing plates. Two guiding shafts that slidably penetrate through the corresponding positioning plate and the vertical section of the L-shaped support are fixedly installed at the front end of the middle pushing plate.

[0014] As a preferred solution, the positioning plate is fixedly installed at the lower end of the corresponding fixing plate and in front of the corresponding T-shaped block. The limiting post slidably penetrates through the vertical section of the corresponding T-shaped block from front to back. A convex ring is arranged on the limiting post. A compression spring sleeved on the limiting post is installed between the rear end of the convex ring and the T-shaped block.

[0015] As a preferred solution, a fixing member for fixing the pushing plate after moving the moving pushing T-shaped block is provided on the pushing plate; the fixing member includes a fixing rod, and a fixing rod is fixedly installed together between the pushing plates corresponding to the same fixing plate. The front end of the fixing rod slidably penetrates through all the positioning plates and the supporting plates or L-shaped supports and is fixed to the corresponding supporting plate or L-shaped support by a second nut.

[0016] As a preferred solution, the locking member includes a clamping plate. Circular grooves corresponding to the buffer springs are opened at the upper end of the buffer rubber strip. Through grooves are penetrated through the bottom walls of the circular grooves of the buffer rubber strip. A clamping plate is fixedly installed at the upper end of the upper disc through a support column. After the clamping plate penetrates through the corresponding through groove from top to bottom, it rotates 90 degrees to be perpendicular to the through groove and the upper disc closely adheres to the lower end surface of the buffer rubber strip, restricting the clamping plate from moving into the through groove.

[0019] Second, the present invention adopts a cooperative energy absorption design of the buffer spring and the buffer rubber strip, uses the compression and rebound characteristics of the buffer spring to dynamically disperse the impact energy, reduces the local stress concentration of the buffer rubber strip, reduces the risk of plastic deformation or cracking, and improves the buffering effect of the buffer bed at the same time.

[0020] Third, the buffer rubber strip provided in the present invention is quickly connected to the buffer spring through the rotation and clamping of the clamping plate, and the quick assembly is realized by driving the insertion of the limiting column through the movement of the T-shaped block. When replacing, only need to move the pushing plate backward to release the limiting column, greatly reducing the amount of bolts used.

[0021] Fourth, the present invention adopts a sliding interlocking design of the support frame and the fixing plate to simplify the positioning process, and cooperates with the guide shaft of the locking part and the pushing plate to be locked in one key, reducing the manual operation intensity and simplifying the assembly of the buffer bed.

Detailed implementation manners

[0032] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] Such asFigure 1 As shown in the figure, a buffer bed of a belt conveyor includes a plurality of support components 4 distributed front and back. Three fixing plates 1 arranged from left to right are commonly provided on the support components 4. The middle fixing plate 1 is horizontally arranged on the support components 4, and the fixing plates 1 on both sides are inclined in an inverted V shape on the support components 4. A buffer mechanism 2 is arranged on the fixing plates 1.

[0034] As Figure 1 、 Figure 2 and Figure 3 As shown in the figure, the buffer mechanism 2 includes a support frame 20. Concave-structured support frames 20 are evenly arranged on the upper ends of the fixing plates 1 from left to right. T-shaped blocks 21 fixedly installed at the lower ends of the support frames 20 are arranged between adjacent two support components 4. Waist-shaped grooves in sliding fit with the T-shaped blocks 21 one by one are formed on the fixing plates 1. A buffer rubber strip 22 is slidably installed in the support frame 20. Buffer springs 23 corresponding to the T-shaped blocks 21 one by one are detachably installed between the buffer rubber strip 22 and the support frame 20. A limiting part 3 is commonly arranged on the fixing plates 1 and the T-shaped blocks 21.

[0035] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in the figure, the limiting part 3 includes a locking member for fixing the buffer spring 23 and a connecting block 30. The connecting block 30 slidably penetrates through the T-shaped block 21 on the buffer spring 23. Positioning plates 31 corresponding to the fixing plates 1 one by one are arranged between adjacent two support components 4. And a section of the T-shaped block 21 perpendicular to the corresponding support frame 20 (i.e., the vertical section of the T-shaped block 21) is located between the corresponding connecting block 30 and the positioning plate 31. A limiting post 32 is slidably installed on the T-shaped block 21. During the process of the support frame 20 driving the T-shaped block 21 to move forward, the front and rear ends of the limiting post 32 respectively penetrate through the positioning plate 31 and the connecting block 30; A locking part 5 for fixing the moved support frame 20 is arranged on the support component 4.

[0036] During specific work, first, the buffer spring 23 is installed on the buffer rubber strip 22 manually, then the buffer rubber strip 22 is installed into the support frame 20, and the connecting block 30 slidably penetrates through the support frame 20 and the T-shaped block 21. Then, the support frame 20 installed with the buffer rubber strip 22 is installed on the corresponding fixing plate 1 in sequence, and the connecting block 30 and the T-shaped block 21 penetrate through the waist-shaped groove. Then, the support frame 20 is moved forward to make the front and rear ends of the limiting post 32 respectively penetrate through the positioning plate 31 and the connecting block 30, and then the support frame 20 installed with the buffer rubber strip 22 and moved forward is fixed through the locking part 5, so as to realize the rapid assembly of the buffer bed.

[0037] As Figure 2 and Figure 5As shown, the limiting portion 3 includes a disc 33. Discs 33 are fixedly installed at both the upper and lower ends of the buffer spring 23. The lower end of the lower disc 33 is fixedly connected to the upper end of the connecting block 30, and the upper disc 33 is detachably installed on the buffer rubber strip 22.

[0038] As Figure 2 and Figure 6 shown, the locking member includes a clamping plate 34. Circular grooves corresponding to the buffer springs 23 are formed at the upper end of the buffer rubber strip 22. Through grooves 220 are formed through the bottom walls of the circular grooves of the buffer rubber strip 22. A clamping plate 34 is fixedly installed at the upper end of the upper disc 33 through a support column. After passing through the corresponding through groove 220 from bottom to top, the clamping plate 34 rotates 90 degrees to be perpendicular to the through groove 220, and the upper disc 33 closely adheres to the lower end surface of the buffer rubber strip 22, restricting the clamping plate 34 from moving into the through groove 220.

[0039] As Figure 1 , Figure 2 and Figure 3 shown, the support assembly 4 includes two channel steels 40 that are symmetrically arranged front and back and have openings facing away from each other. A bottom plate 41 is fixedly installed at the upper ends of the two channel steels 40. A rectangular groove communicating with the gap between the two channel steels 40 is formed in the middle of the bottom plate 41. Two symmetrically arranged support plates 42 are rotatably installed between the two channel steels 40 through a shaft column. The upper end surface of the support plate 42 is an inclined surface that slopes downward from top to bottom towards the middle of the bottom plate 41. The inclined surfaces of the support plates 42 arranged front and back and on the same side are fixedly connected to the corresponding fixing plate 1 together. An adjusting member 44 for adjusting the angle of the support plate 42 is provided on the support plate 42 and the bottom plate 41 together.

[0040] As Figure 1 , Figure 2 and Figure 3 shown, the support assembly 4 further includes an L-shaped support 43 fixedly installed in the middle of the bottom plate 41. The upper ends of the vertical sections of the L-shaped supports 43 of multiple support assemblies 4 are fixedly connected to the middle fixing plate 1.

[0041] As Figure 2 and Figure 3 shown, the adjusting member 44 includes an arc-shaped groove 440. An arc-shaped groove 440 concentric with the corresponding shaft column is formed on the support plate 42. A support seat is fixedly installed on the bottom plate 41. A bolt 441 is threadedly connected to the support seat. The bolt 441 slidably passes through the arc-shaped groove 440 and is then installed with a first nut. The support plate 42 is fixed to the support seat through the cooperation of the bolt 441 and the first nut.

[0042] As Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, during specific operation, loosen nut 1, and then rotate support plate 42. Bolt 441 slides within arc-shaped groove 440 to adjust the inclination angle of the inclined plane on support plate 42 to adapt to different types of materials. A small angle is suitable for large or sticky materials, mainly reducing the risk of blockage and buffering the friction of buffer strip 22; a medium angle is suitable for conventional bulk materials, balancing the centering of materials and impact dispersion; a large angle is for high-speed or fine-particle materials, strengthening the effects of guiding the conveyor belt and preventing spillage control, etc. After adjusting support plate 42 to an appropriate angle, manually lock nut 1 to make support plate 42 closely adhere to and fix with the support seat. After the fixation is completed, manually insert clamping plate 34 upward through the corresponding through groove 220 from bottom to top, and then rotate clamping plate 34 by ninety degrees to make clamping plate 34 perpendicular to through groove 220, and clamping plate 34 abuts against the inner wall of the circular groove. The upper disc 33 closely adheres to the lower end surface of buffer strip 22, thereby realizing the installation of buffer spring 23 onto buffer strip 22. After the installation is completed, install buffer strip 22 with buffer spring 23 installed onto support frame 20, and make connecting block 30 penetrate through support frame 20 and T-shaped block 21 to limit buffer strip 22.

[0043] When buffer strip 22 needs to be disassembled and replaced, release the fixation of locking portion 5 on support frame 20 and separate limit post 32 from positioning plate 31. Then, manually remove buffer strip 22 from support frame 20, and make connecting block 30 disengage from T-shaped block 21 and support frame 20. Then, rotate the upper disc 33 by ninety degrees. This disc 33 drives clamping plate 34 to rotate by ninety degrees through the support pillar to be parallel to through groove 220. At this time, clamping plate 34 can be moved downward through through groove 220 to disengage from buffer strip 22. After that, buffer strip 22 can be replaced, and then repeat the above installation operation to install the replaced buffer strip 22 onto support frame 20.

[0044] As Figure 1 、 Figure 2 and Figure 3 shown, the locking portion 5 includes a pushing plate 50. Between two adjacent support assemblies 4, there are pushing plates 50 corresponding to fixing plates 1 one by one and located at the rear side of corresponding T-shaped blocks 21. At the front ends of the left and right pushing plates 50, two guiding shafts 51 are fixedly installed and slide through the corresponding positioning plates 31 and support plates 42. At the front end of the middle pushing plate 50, two guiding shafts 51 are fixedly installed and slide through the corresponding positioning plates 31 and the vertical sections of L-shaped supports 43. A fixing member 52 is provided on pushing plate 50 for fixing pushing plate 50 after moving and pushing T-shaped block 21.

[0045] As Figure 1 、 Figure 2 and Figure 3 ​As shown, the fixing member 52 includes a fixing rod 520. A fixing rod 520 is fixedly installed between the pushing plates 50 corresponding to the same fixing plate 1. The front end of the fixing rod 520 slidably penetrates through all the positioning plates 31 and the support plates 42 or the L-shaped supports 43 and is fixed to the corresponding support plate 42 or L-shaped support 43 by a second nut.

[0046] As Figure 3 , Figure 4 and Figure 5 shown, the positioning plate 31 is fixedly installed at the lower end of the corresponding fixing plate 1 and is located in front of the corresponding T-shaped block 21. The limiting post 32 slidably penetrates through the vertical section of the corresponding T-shaped block 21 back and forth. A convex ring 320 is arranged on the limiting post 32. A compression spring 321 sleeved on the limiting post 32 is installed between the rear end of the convex ring 320 and the T-shaped block 21; a positioning post 210 that slidably penetrates through the corresponding positioning plate 31 is fixedly installed at the front end of the T-shaped block 21.

[0047] During specific operation, after all the support frames 20 are installed on the corresponding fixing plates 1, the pushing plate 50 is manually moved forward. The pushing plate 50 drives the fixing rod 520 to move along the guide shaft 51. After the pushing plate 50 contacts the T-shaped block 21, it will push the corresponding T-shaped block 21 so that the T-shaped block 21 drives the corresponding support frame 20 to move forward. The forward movement of the T-shaped block 21 will also drive the limiting post 32 to move forward, and the front end of the limiting post 32 penetrates through the corresponding positioning plate 31, restricting the T-shaped block 21 from detaching from the fixing plate 1. When the convex ring 320 abuts against the positioning plate 31, the T-shaped block 21 continues to move forward. Since the convex ring 320 abuts against the positioning plate 31, the limiting post 32 cannot move further. Thus, the T-shaped block 21 will compress the compression spring 321 and continue to move forward, enabling the rear end of the limiting post 32 to penetrate through the connecting block 30, so that the connecting block 30 and the T-shaped block 21 are interlocked bidirectionally. At this time, the front end of the fixing rod 520 penetrates through the corresponding support plate 42 or L-shaped support 43, and then the moved fixing rod 520 is fixed to the support plate 42 or L-shaped support 43 by a second nut.

[0048] When the buffer rubber strip 22 needs to be replaced due to wear or other reasons, first remove the second nut, and then move the extrusion plate 50 backward to make the extrusion plate 50 away from the corresponding T-shaped block 21. After that, move the support frame 20 of the buffer rubber strip 22 to be replaced backward. The support frame 20 drives the corresponding limit post 32 to move through the corresponding T-shaped block 21. Under the action of the compression spring 321, the convex ring 320 first keeps in contact with the positioning plate 31 until the limit post 32 is completely separated from the connection block 30. At this time, the compression spring 321 returns to its original state. Then, as the support frame 20 continues to move backward, the convex ring 320 is driven to separate from the positioning plate 31 through the T-shaped block 21 and the compression spring 321. After that, move the buffer rubber strip 22 away from the support frame 20. The buffer rubber strip 22 also drives the buffer spring 23 and the connection block 30 to separate from the support frame 20. Then rotate the clamping plate 34 by 90 degrees to be parallel to the through groove 220. At this time, the buffer rubber strip 22 can be removed and replaced. Then, install the buffer rubber strip 22 onto the support frame 20 according to the above operation, and then install the support frame 20 with the buffer rubber strip 22 onto the fixed plate 1 for fixation.

[0049] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself. In addition, in the description of the present invention, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0050] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "connected", "installed", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0051] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
