Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyors, in particular to a belt conveyor with a shock-absorbing function. Background Art

[0002] A conveyor is a material handling machine that continuously transports materials along a certain route. It is also called a continuous conveyor. Belt conveyors can be used to transport products such as coal and minerals.

[0003] Belt conveyors can be used for horizontal and inclined conveying. Figure 1 As shown, it includes a frame 10, a conveyor belt 101, and a driving mechanism for driving the conveyor belt 101 to operate.

[0004] In the actual production process, you can refer to Figure 1 , materials are loaded onto the conveyor belt 101 through the unloading hopper. At this time, the materials fall onto the conveyor belt 101, generating a downward impact force on the conveyor belt 101, so that the entire frame 10 has a tendency to move downward. At this time, the frame 10 is prone to vibration. For this reason, a first bracket 102 and a second bracket 103 are installed at the bottom of the frame 10, wherein a shock absorbing mechanism 105 is installed between the second bracket 103 and the frame 10 to reduce the vibration of the frame 10;

[0005] In order to prevent the material from being separated from the conveyor belt 101 during the conveying process, a V-shaped guide roller 104 is provided on the belt conveyor to concentrate the material at the bottom end of the conveyor belt 101.

[0006] When the material falls on the conveyor belt 101, Figure 2 As shown, in the initial state, the height between the conveyor belt 101 and the discharge hopper is h. When the material impacts the conveyor belt 101, the frame 10 sinks as a whole, and the h value becomes larger. Moreover, the existing guide roller 104 cannot adjust its inclination angle as the frame 10 sinks. As the material falls, the bottom material diffuses to the surrounding side, causing the material to easily spill to the outside of the conveyor belt 101, thereby affecting the transportation of the material.

[0007] Therefore, how to design a belt conveyor that prevents materials from falling to the outside of the conveyor belt has become a technical problem that needs to be solved urgently by people in this field. Summary of the Invention

[0008] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present invention is to provide a belt conveyor with a shock-absorbing function to solve the problem that when materials fall onto the conveyor belt and cause the frame to sink, the materials spill to the outside of the conveyor belt.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] The top of the second support roller is hinged on the base and the second support roller is hinged on the base to form a coaxial cable, and the bottom of the support roller is hinged on the base and the second support roller is hinged on the base to form a coaxial cable.

[0011] Furthermore, the second support frame also includes a push plate, which is rotatably mounted on the top of the support rod via a third rotating shaft, and the push plate is slidably connected to the bottom wall of the frame.

[0012] Furthermore, the bottom wall of the frame is fixedly connected to a touch plate, the bottom wall of the touch plate is provided with a guide groove arranged along the side of the body, the push plate is fixedly provided with a guide column extending into the guide groove, and the guide column is slidably connected to the inner wall of the guide groove.

[0013] Furthermore, a first gap is left between the outer wall of the guide column and the side walls of the guide groove for the machine body to flip around the first support frame.

[0014] Furthermore, the bottom of the positioning plate is fixed on the push plate, and the side wall of the positioning plate abuts against the side wall of the through groove.

[0015] Furthermore, the shock absorbing assembly includes a damper and a spring, the damping body of the damper is rotatably mounted on the base, one end of the damping rod of the damper is hinged to the support rod, and the other end thereof extends into the damping body and forms a sliding connection, one end of the spring is fixed on the outer wall of the damping body, and the other end thereof is against the support rod.

[0016] Furthermore, a support assembly for mounting the damper is fixedly mounted on the base, and the support assembly includes a support plate fixed to the base and extending upward, and the support plate is rotatably connected to the damping body via a fourth rotating shaft.

[0017] Furthermore, the first support frame includes a frame body, and the frame body is rotatably mounted on the side wall of the frame via a first rotating shaft.

[0018] Compared with the prior art, the present invention has the following advantages: the second support frame installed at the bottom of the body supports the body, and the shock-absorbing assembly installed between the support rod and the base pushes the support rod to enhance the stability of the support rod;

[0019] When unloading onto the conveyor belt, the end of the machine body sinks and exerts pressure on the second support frame, causing the second support frame to slide laterally toward the machine body. At this time, the shock-absorbing component is deformed under pressure, absorbing the energy of the machine body vibration and slowing down the sinking of the machine body;

[0020] When the second support frame sinks, it drives the positioning plate to slide laterally toward the machine body, and drives the second support roller to flip outward around the support seat through the support rod. At this time, the second support rollers on both sides unfold, and then the conveyor belt on the upper side of the support roller group can be expanded outward, thereby increasing the conveyor belt's receiving area for materials and preventing materials from falling to the outside of the conveyor belt.

[0032] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] This embodiment provides a belt conveyor with a shock-absorbing function, which mainly absorbs the vibration energy when the conveyor belt carries falling materials. As the end of the conveyor sinks, the expansion angle of the V-shaped conveyor belt is expanded to better carry the falling materials and prevent the materials from falling to the outside of the conveyor belt.

[0034] like Figure 3 As shown, in this embodiment, the belt conveyor includes a body, wherein the body is composed of two symmetrically arranged frames 21 and a partition 22, and the partition 22 is fixedly installed between the two frames 21;

[0035] like Figure 3 As shown, the body includes a first end and a second end, the first end is located on the bottom side of the body, and the second end is located on the top side of the body. A driven roller 24 is rotatably connected between the bottoms of the two frames 21, and an active roller 23 is rotatably connected between the tops of the two frames 21, wherein the conveyor belt 101 is sleeved on the outside of the driven roller 24 and the active roller 23.

[0036] In order to rotate the conveyor belt 101, in this embodiment, as shown in FIG. Figure 3As shown, a motor 25 is fixedly connected to the side wall of the frame 21 , and an output shaft of the motor 25 is fixedly connected to the rotating shaft of the active roller 23 , thereby driving the active roller 23 to rotate.

[0037] In order to prevent materials from flying out from the edge of the conveyor belt 101 during the conveying process, in this embodiment, several groups of V-shaped guide rollers 27 are provided on the top of the partition 22 to shape the conveyor belt 101, and at the same time can support the bottom of the conveyor belt 101, so that the conveyor belt 101 can stably convey materials.

[0038] In this embodiment, in order to realize the installation of the guide roller set 27, as shown in FIG. Figure 4 and Figure 5 As shown, the guide roller group 27 has two support seats 271 fixed on the partition 22, and a first support roller 272 is rotatably installed between the two support seats 271 to support the bottom of the conveyor belt 101, and a second support roller 273 extending obliquely upward is rotatably installed on the side of the support seat 271 to gather the side of the conveyor belt 101 so that the conveyor belt 101 can be displayed in a V shape.

[0039] When the material falls onto the conveyor belt 101, the material will generate a downward impact force on the conveyor belt 101 and the body, causing the body to tend to sink. If the support frame of the body is fixedly connected to the frame 21 and placed on the ground, the impact energy of the material on the conveyor belt 101 cannot be absorbed, which can easily cause damage to the conveyor belt 101. Therefore, it is necessary to absorb the impact energy on the conveyor belt.

[0040] Therefore, if Figure 3 and Figure 4 As shown, the side wall of the first end portion of the frame 21 is rotatably connected to a first support frame 26 placed on the ground, and the first support frame 26 includes a frame body 261 and a first rotating shaft 2611. The frame body 261 is triangular in shape and one side is in contact with the ground. The frame body 261 is rotatably connected to the frames 21 on both sides through the first rotating shaft 2611. The bottom side of the second end portion of the frame 21 is provided with a second support frame 3, and the second support frame 3 includes a support rod 32 and a base 31. One end of the support rod 32 is hinged on the base 31 and can be flipped toward the side of the body, and the other end is slidably connected to the bottom wall of the frame 21 and can slide laterally along the width direction of the conveyor belt 101, wherein a shock-absorbing component 4 is provided between the base and the support rod 32 for pushing the support rod 32 and absorbing the impact energy of the conveyor belt 101.

[0041] Through the above arrangement, when the conveyor belt 101 at the second end of the frame 21 carries materials, the entire body is acted upon by gravity, causing the frame 21 to sink and flip around the first rotating shaft 2611. At this time, the second end of the frame 21 applies pressure to the top of the second support frame 3, causing the top of the support rod 32 to slide along the side of the body, as shown in FIG. Figure 4 and Figure 5 As shown in the direction of the arrow in FIG, at this time, the shock absorbing assembly 4 pushes the support rod 32 to absorb the energy of the vibration, thereby preventing the conveyor belt 101 from being damaged by the impact.

[0042] The second support frame 3 also includes a push plate 33, the base 31 is placed on the ground, and a mounting seat 6 is fixedly installed on the base 31. The bottom of the support rod 32 is rotatably installed on the mounting seat 6 through the fifth rotating shaft 61, and the push plate 33 is rotatably installed on the top of the support rod 32 through the third rotating shaft 332, wherein the push plate 33 is slidably connected to the bottom wall of the frame 21.

[0043] Through the above arrangement, when the second end of the frame 21 is subjected to a downward impact force, the frame 21 transfers the impact force to the second support frame 3, such as Figure 7 As shown, at this time, the support rod 32 flips outward around the fifth rotation axis 61, and the frame 21 rotates and sinks downward around the first rotation axis 2611. At this time, the support rod 32 drives the push plate 33 to flip and slide relative to the bottom wall of the frame 21 and slide outward. At this time, the shock absorbing assembly 4 located on one side of the support rod 32 absorbs the impact force and slows down the flipping speed of the support rod 32.

[0044] In order to realize the installation of the shock absorbing assembly 4, in this embodiment, as shown in FIG. Figure 4 、 Figure 5 and Figure 7 As shown, the shock absorbing assembly 4 includes a damper 41 and a spring 42. The damping body 411 of the damper 41 is rotatably connected to the base 31 and is located on the outside of the support rod 32. One end of the damping rod 412 of the damper 41 is hinged to the outer wall of the support rod 32, and the other end extends into the damping body 411 and forms a sliding connection. The spring 42 is sleeved on the outside of the damper 41 and one end is fixedly connected to the outer wall of the damping body 411, and the other end is against the outer wall of the support rod 32.

[0045] Through the above-mentioned arrangement, when the support rod 32 flips outward around the fifth rotating shaft 61, it drives the damping rod 412 to shrink toward the inside of the damping body 411, and the spring 42 is compressed. At this time, the damper 41 absorbs the vibration energy. As the flipping angle of the support rod 32 increases, the pushing force generated by the damper 41 on the support rod 32 becomes greater. When the limit state is reached, the support rod 32 stops flipping outward; when the material on the conveyor belt 101 at the second end of the frame 21 is transported away, the spring 42 drives the damping rod 412 to extend, so that the damper 41 is reset.

[0046] In order to realize the installation of the damper 41, in this embodiment, as shown in FIG. Figure 5 As shown, a support assembly 5 for installing the damper 41 is installed on the base 31, and the support assembly 5 includes a support plate 51 fixed on the base 31 and extending upward, and the support plate 51 is located on the outside of the support rod 32, and the damping body 411 is rotatably connected to the support plate 51 through a fourth rotating shaft 52.

[0047] In order to strengthen the sliding connection between the frame 21 and the push plate 33, in this embodiment, as shown in FIG. Figure 7 and Figure 8 As shown, the bottom of the frame 21 is fixedly connected to a touch plate 28 by bolts, and the touch plate 28 is provided with a guide groove 281 arranged along the width direction of the conveyor belt 101. Figure 9 As shown, a guide column 331 extending into the inside of the guide groove 281 is fixed on the top of the push plate 33, and the guide column 331 is slidably connected to the side wall of the guide groove 281; the sliding connection between the push plate 33 and the touch plate 28 can reduce the wear on the frame 21 and extend the service life of the conveyor.

[0048] In order to enhance the stability of the sliding connection between the push plate 33 and the touch plate 28, in this embodiment, as shown in FIG. Figure 9 and Figure 10 As shown, two parallel guide grooves 281 are provided on the lower wall of the touch plate 28 , and two guide posts 331 are provided on the push plate 33 , respectively extending into the corresponding guide grooves 281 .

[0049] Since the second end of the frame 21 rotates around the first rotating shaft 2611, there is a relative slip between the frame 21 and the push plate 33 along the conveying direction of the conveyor belt 101. In order to solve this problem, Figure 10 As shown, a first gap 801 is left between the outer wall of the guide column 331 and the side wall of the guide groove 281 to accommodate the relative sliding between the frame 21 and the push plate 33.

[0050] Since the support rod 32 rotates around the fifth rotation axis 61 each time, the support rod 32 drives the push plate 33 to flip, in order to prevent the top of the guide column 331 from abutting against the top wall of the guide groove 281 to limit the flipping action of the push plate 33, in this embodiment, as shown in FIG. Figure 10 As shown, a second gap 802 is left between the top of the guide post 331 and the top wall of the guide groove 281 to allow the push plate 33 to flip.

[0051] In the prior art, such as Figure 2 As shown, when the second end of the frame sinks, the distance h between the discharge hopper and the conveyor belt 101 becomes larger. At this time, the material will spread outward during the falling process, causing the material to fall on the outside of the conveyor belt 101. In order to prevent the material from being spilled when the frame 21 sinks, it is best to adjust the slope of the V-shaped conveyor belt 101 here so that it can better receive the material.

[0052] Therefore, in this embodiment, if Figure 6 and Figure 8 As shown, there are two support seats 271 in the guide roller group 27, and the end surfaces close to each other are first mounting surfaces 2711, and the first support roller 272 is rotatably mounted between the first mounting surfaces 2711. Figure 6 As shown, the support seat 271 is provided with a second mounting surface 2712 inclined upward and outward, and the second mounting surface 2712 is hinged with a second rotating shaft 2371, and the outer wall of the second rotating shaft 2371 is rotatably connected to a roller 2732, wherein the second rotating shaft 2731 and the roller 2732 are combined into a second support roller 273, and the second rotating shaft 2371 extends obliquely upward and is hinged with a support rod 71 extending obliquely downward, and the other end of the support rod 71 is hinged with a positioning plate 7 extending downward and fixed to the push plate 33; wherein the outer walls of the first support roller 272 and the second support roller 273 are against the bottom wall of the conveyor belt 101.

[0053] With the above settings, Figure 8 As shown, in the initial state, the pushing plate 33, the positioning plate 7, the first support roller 272 and the second support roller 273 are shown as solid lines. When the second end portion at the frame 21 sinks, the pushing plate 33 flips to the dotted line position, thereby driving the positioning plate 7, the support rod 71 and the second support roller 273 to flip outward to the dotted line position. At this time, the expansion angle between the support rollers 273 on both sides becomes larger, and then the expansion angle of the conveyor belt 101 here becomes larger, thereby increasing the receiving area for the material, preventing the material from being scattered to the outside of the conveyor belt 101 when falling.

[0054] In order to enable the positioning plate 7 to pass through the partition 22, in this embodiment, as shown in FIG. Figure 4 and Figure 7As shown, a through slot 221 is provided on the partition 22, and the through slot 221 is arranged along the width direction of the conveyor belt 101. At this time, the positioning plate 7 passes through the through slot 221 and the side wall of the positioning plate 7 is against the side wall of the through slot 221, and the positioning plate 7 can slide inside the through slot 221.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
