[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-9 A heavy-duty, high-efficiency buffer conveyor, comprising: Multiple supports 1, multiple side support frames 2 are provided above the multiple supports 1, multiple positioning seats 5 are installed on the top of the multiple supports 1, and each of the multiple positioning seats 5 has a protruding strip 6 fixed on its top. Each of the multiple positioning seats 5 has a buffer strip 7 installed on its top, and each of the multiple buffer strip 7 has a protruding groove 8 on its inner wall; also includes: Multiple sets of support parts 3 installed inside the support 1 are used to support and position the positioning seat 5 on the side. The support part 3 includes a support arm 301, the top of the support arm 301 is rotatably connected to the bottom of the side support frame 2, and the bottom of the support arm 301 is rotatably connected to a slider 302.

[0021] The buffer part 4 installed inside the support 1 is used to buffer the force when the support part 3 moves. Multiple positioning parts 9 installed inside the positioning base 5 are used to position the buffer strip 7. The positioning part 9 includes a circular cover 91, which is fixed to the bottom of the positioning base 5. A circular groove 92 is provided on the top of the protrusion 6, which communicates with the inner wall of the circular cover 91. A return spring 93 is fixedly connected to the inner bottom of the circular cover 91, and a retaining ball 94 is fixedly connected to the top of the return spring 93. The abutment 11, installed on the side of the positioning seat 5, is used to remove the buffer strip 7.

[0022] In this design: support 1 serves as the base, evenly distributing the overall pressure generated by heavy-duty materials; side support frame 2 is mounted above support 1, forming a lateral support system with support part 3, which can laterally limit the conveying structure, preventing the equipment from shifting or shaking when materials impact, ensuring a neat conveying line; positioning seat 5 is fixed on the top of support 1, providing a stable carrier for buffer strip 7, protrusion 6, and positioning part 9, concentrating the vertical impact force brought by falling materials; protrusion 6 and the convex groove 8 inside buffer strip 7 interlock to achieve initial limiting of buffer strip 7, preventing the buffer strip 7 from sliding or shifting laterally under material friction and impact, while increasing the contact area between the two and improving the uniformity of force distribution; The support part 3 is located inside the support 1 and is used to support and position the positioning seat 5. The support arm 301 is connected to the side support frame 2 and the slider 302 by a rotating connection, which can convert the vertical impact load into the horizontal displacement force and realize the transmission and diversion of force. The slider 302 slides synchronously with the support arm 301, providing a force trigger point for the buffer part 4, so that the impact force can be smoothly transmitted to the buffer part 4. The buffer 4 is integrated inside the support 1, which can buffer and absorb the impact force generated during the movement of the support 3 in stages, greatly reduce the rigid impact caused by the falling material, reduce the vibration amplitude of the support 1, and reduce the wear and damage of other components. The positioning part 9 is embedded inside the positioning seat 5 to lock and fix the buffer strip 7. The circular cover 91 provides a sealed installation space for the return spring 93 and the retaining ball 94 to prevent dust and material debris from entering and causing jamming. The circular groove 92 allows the retaining ball 94 to extend and retract flexibly. The return spring 93 continuously pushes the retaining ball 94 with its own elasticity, so that the retaining ball 94 always remains in a locked state. The retaining ball 94, together with the groove structure, locks the buffer strip 7 to prevent it from loosening under strong impact. The abutment part 11 is assembled on the side of the positioning seat 5 and is specifically used to assist in the disassembly and assembly of the buffer strip 7. This changes the cumbersome traditional method of overall disassembly, simplifies the replacement process of the buffer strip 7, and reduces the difficulty of equipment maintenance.

[0023] See Figure 3 and Figure 4 The support 1 includes a steel frame 101 and a steel frame 102. The steel frame 101 and the steel frame 102 are symmetrically arranged, and positioning frames 103 are fixed on both sides of the steel frame 101 and the steel frame 102. A slide rail 104 is provided between the steel frame 101 and the steel frame 102. A slide rail 205 is provided on the side of the steel frame 102 and communicates with the slide rail 104.

[0024] In this design, support 1 adopts a symmetrically arranged combination structure of steel frame 101 and steel frame 102. The double steel frames are symmetrically stressed, which greatly improves the overall load-bearing capacity and structural strength of support 1, effectively resisting the continuous impact of heavy materials and preventing bending and cracking. The positioning frames 103 fixed on both sides can laterally reinforce and limit the position of steel frame 101 and steel frame 102, preventing relative displacement of the two steel frames during the stress process and ensuring the integrity of the overall frame of support 1. The slide rail 104 between steel frame 101 and steel frame 102 provides a regular sliding track for slider 302, restricting the movement trajectory of slider 302 and ensuring that the sliding process of support 3 is smooth and without jamming.

[0025] See Figure 3 and Figure 4 The buffer part 4 includes a buffer spring 401, which is connected between two sliders 302. One end of the second buffer spring 402 is fixedly connected to the slider 302, and the other end of the second buffer spring 402 is fixed to a positioning plate 403. The positioning plate 403 is fixed to the inner wall of the slide rail 104. A pressing rod 405 is fixed to the side wall of the positioning plate 403. A pressure sensor 404 is fixed to the side of the slider 302 near the pressing rod 405.

[0026] In this design: Buffer spring 401 connects two sets of sliders 302, providing primary energy absorption and buffering during relative movement of the sliders 302, offsetting some of the lateral impact force. Simultaneously, it provides reset traction to the sliders 302 on both sides, ensuring the support part 3 can quickly return to its initial position after being subjected to force. Buffer spring 402 serves as a secondary buffer structure, with one end moving with the slider 302 and the other end fixed to the positioning plate 403. It absorbs the main impact load transmitted vertically. The combination of these two springs achieves graded buffering, resulting in superior buffering performance and significantly reducing equipment vibration. The positioning plate... 403 is fixed to the inner wall of slide rail 104, providing a support base for buffer spring 402, preventing the root of buffer spring 402 from shaking or falling off when under force. The extrusion rod 405 is fixed with the positioning plate 403 and can cooperate with the pressure sensor 404 to trigger the detection signal. The pressure sensor 404 is installed at the corresponding position of the slider 302. When the slider 302 slides and contacts the extrusion rod 405, it can detect the impact pressure value in real time, which makes it easy for the staff to keep abreast of the stress status of the equipment, and promptly check for faults such as overload and abnormal impact, thereby improving the safety of equipment operation.

[0027] See Figure 6 and Figure 7 The ball 94 is slidably connected to the inner wall of the circular groove 92. The semicircle of the ball 94 is set on the top of the protrusion 6. The inner top of the convex groove 8 is provided with a semicircular groove, and the top semicircle of the ball 94 is set on the inner wall of the semicircular groove.

[0028] In this design: the locking ball 94 slides smoothly along the inner wall of the circular groove 92, ensuring that the extension and retraction of the locking ball 94 is flexible and without jamming; the lower half of the locking ball 94 is embedded in the top of the protruding strip 6, and the upper half is inserted into the semi-circular groove inside the convex groove 8. The spherical locking structure realizes the rigid locking of the protruding strip 6 and the buffer strip 7. The locking contact is an arc surface, which distributes the force evenly and has strong impact resistance. Even under frequent strong impact conditions, it can effectively prevent the buffer strip 7 from separating and loosening from the protruding strip 6. At the same time, the spherical structure can achieve smooth release during disassembly.

[0029] See Figure 6 and Figure 7 A pull rod 95 is fixed to the bottom of the ball 94. The pull rod 95 passes through the middle of the return spring 93 and is slidably connected to the circular cover 91. A linkage plate 10 is fixed to the bottom of the pull rod 95.

[0030] In this design: the pull rod 95 is rigidly connected to the locking ball 94, and passes through the return spring 93 and is slidably assembled inside the circular cover 91. Pulling the pull rod 95 will cause the locking ball 94 to retract downward, releasing the locking ball 94 from the buffer strip 7. The linkage plate 10 is set at the bottom of the pull rod 95 as the force-bearing operating end, which can simultaneously drive multiple sets of pull rods 95 to move in linkage, realizing the simultaneous unlocking of multiple locking balls 94. There is no need to operate the positioning part 9 one by one, which further simplifies the disassembly operation of the buffer strip 7 and improves maintenance efficiency.

[0031] See Figure 8 and Figure 9 The abutment member 11 includes a pressing plate 1101, which is located on the side of the positioning seat 5. Multiple pushers 1102 are installed on the side of the pressing plate 1101 near the positioning seat 5. Multiple pins 1103 are fixed on the side of the pressing plate 1101 and are inserted into the inner wall of the positioning seat 5. Nuts 1104 are threadedly connected to the outer edges of the multiple pins 1103 and abut against the inner wall of the positioning seat 5.

[0032] In this design: the pressing plate 1101 serves as the external operating component of the abutment 11, and is arranged on the outside of the positioning seat 5, providing ample operating space for easy force application by the operator; the pusher 1102 is fixed to the inside of the pressing plate 1101 and moves synchronously with the pressing plate 1101, directly applying a pushing force to the buffer strip 7 to assist the buffer strip 7 in disengaging from its installation position, reducing the labor intensity of manual disassembly; the pin 1103 inserts the pressing plate 1101 into the inner wall of the positioning seat 5, achieving the guiding and limiting of the pressing plate 1101, ensuring that the pressing plate 1101 moves smoothly only along the axial direction of the pin 1103, without deviation or skew; the nut 1104 is threaded onto the outside of the pin 1103 and abuts against the positioning seat 5, restricting the pin 1103 from disengaging and ensuring that the components do not fall apart during operation.

[0033] See Figure 8 and Figure 9 Multiple pushers 1102 abut against the side wall of the buffer strip 7 on the side away from the pressing plate 1101.

[0034] In this design, the end of the pusher 1102 is directly attached to the side wall of the buffer strip 7, and the force points are evenly distributed. When force is applied, a balanced pushing force can be applied to the entire buffer strip 7, avoiding deformation and damage to the buffer strip 7 caused by single-point force. At the same time, the pushing direction is consistent with the disassembly direction of the buffer strip 7, which can efficiently push out the buffer strip 7 in the locked state and improve the disassembly efficiency. In addition, when installing the buffer strip 7, one side of the buffer strip 7 can be easily aligned with one side of the protrusion 6.

[0035] See Figure 9 One end of a push spring 1105 is fixedly connected to the outer wall of the positioning seat 5, and the other end of the push spring 1105 is fixedly connected to the outer wall of the positioning seat 5. A pin 1103 passes through the inner wall of the push spring 1105.

[0036] In this design: the push spring 1105 is fitted outside the pin 1103, and its two ends are supported by the positioning seats 5 to form elastic support. After the buffer strip 7 is removed and the pressing plate 1101 is released, the push spring 1105 can automatically push the pressing plate 1101 to reset by its own elasticity, so that the abutment 11 returns to its initial state without manual return. At the same time, the push spring 1105 can provide elastic buffer for the pressing plate 1101 to avoid hard impact between the pressing plate 1101 and the positioning seat 5 when the pressing plate 1101 returns to its original position.

[0037] See Figure 3 and Figure 4 The slider 302 is slidably connected to the inner wall of the slide rail 104. The inner wall of the slider 302 is fixed with a screw 303, and the outer edge of the screw 303 is threaded with two nuts 304. The two nuts 304 abut against the outer walls of the steel frame 101 and the steel frame 2 102 respectively.

[0038] In this design: the slider 302 slides directionally within the slide rail 104 to ensure stable force transmission between the support part 3 and the buffer part 4; the screw 303 is fixed inside the slider 302 and forms a limiting structure with the nuts 304 on both sides to ensure the stability of the slider 302's movement.

[0039] See Figure 1 and Figure 6 The top of the buffer strip 7 is coated with a nano-coating 701, which is a diamond carbon film. The convex strip 6 is fitted with the inner wall of the convex groove 8.

[0040] In this design, the diamond carbon film nano-coating 701 on the top of the buffer strip 7 has the characteristics of high hardness, high wear resistance, and low friction. It can resist the wear caused by long-term friction and impact of materials, greatly extend the service life of the buffer strip 7, and at the same time reduce the frictional resistance between the material and the buffer strip 7, reduce material adhesion and jamming, and improve the smoothness of conveying. The convex strip 6 and the convex groove 8 adopt a clearance fit, which can achieve precise positioning and reserve a small amount of movement margin. When the equipment is subjected to impact and slight deformation, it can prevent the convex strip 6 and the buffer strip 7 from jamming or cracking. At the same time, the clearance structure also facilitates the smooth separation of the two during disassembly and assembly.

[0041] Working principle: First, the falling material generates an impact load on the buffer strip 7. The impact force is then transmitted sequentially to the positioning seat 5, the support 1, and the side support frame 2. After the side support frame 2 is subjected to force, it drives the support arm 301 of the support part 3 to rotate. The bottom end of the support arm 301 pulls the slider 302 to slide along the slide rail 104 inside the support 1. During the movement of the slider 302, it first squeezes the buffer spring 401 of the buffer part 4 to achieve primary energy absorption, and at the same time compresses the buffer spring 402 to complete secondary buffering, effectively weakening the vibration caused by the impact.

[0042] Then, as the slider 302 continues to slide, the pressure sensor 404 on its side wall gradually approaches the extrusion rod 405 on the positioning plate 403. After contact, it collects impact pressure data in real time to realize online monitoring of the equipment's stress state. Under normal operating conditions, the positioning part 9 inside the positioning seat 5 pushes the retaining ball 94 with the return spring 93. The retaining ball 94 is inserted into the semi-circular groove of the convex groove 8 of the buffer strip 7. With the interlocking structure of the convex strip 6 and the convex groove 8, the buffer strip 7 is firmly locked to prevent it from shifting or loosening.

[0043] Finally, when it is necessary to inspect or replace the buffer strip 7, pull down the linkage plate 10, and the pull rod 95 will cause the retaining ball 94 to compress the reset spring 93 and move down, releasing the retaining ball 94 from its locking limit; then press the pressing plate 1101 of the side abutment part 11 of the positioning seat 5, and the pusher 1102 will push the buffer strip 7 simultaneously, so that the side of the buffer strip 7 away from the pressing plate 1101 will disengage from the protrusion 6, and the buffer strip 7 can be pulled off smoothly from the disengaged side; after releasing the pressing plate 1101, push the spring 1105 to drive the pressing plate 1101 to automatically reset, completing the disassembly operation.
