Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe welding technology, and in particular to a device for buffering the material drop point of a belt conveyor. Background Technology

[0002] In belt conveyor systems, when material falls from a height onto the conveyor belt, it generates a significant impact force, especially at the point of impact. Traditional solutions often employ densely arranged shock absorber rollers to absorb this impact. However, shock absorber rollers present several problems in practical applications:

[0003] 1) Short service life: The roller bearings and cylinder are prone to damage, deformation, and jamming under continuous impact;

[0004] 2) Poor buffering effect: The buffer roller assembly uses point or line contact with the material to form a buffer, resulting in a poor buffering effect;

[0005] Therefore, this application provides a device for buffering the material drop point of a belt conveyor to meet the requirements. Utility Model Content

[0006] The purpose of this application is to provide a device for buffering the material drop point of a belt conveyor, in order to solve the technical problems mentioned in the background above.

[0007] To achieve the above objectives, this application provides the following technical solution: a device for buffering the material drop point of a belt conveyor, comprising multiple sets of I-shaped steels arranged in rows and multiple sets of support plates, each set of support plates being installed on the corresponding I-shaped steels, and the upper end of the support plate being provided with a groove, wherein the groove is configured as an isosceles trapezoidal structure;

[0008] It also provides multiple sets of rectangular plates with mounting grooves, and the multiple sets of rectangular plates are arranged along the inner wall of the groove and fixedly connected to multiple support plates. When the mounting groove is detachable, a rectangular elastic buffer strip is installed.

[0009] As a preferred embodiment of this invention, the elastic buffer strip includes a metal support base plate, an elastic buffer outer sleeve, and multiple sets of buffer springs.

[0010] The elastic buffer sleeve is fixed to the inner cavity of the metal support base plate. The inner cavity of the rectangular plate is provided with slots that fit at both ends of the metal support base plate. A metal support top plate is fixed to the top of the inner cavity of the elastic buffer sleeve. The metal support top plate and the metal support base plate are connected by multiple sets of buffer springs.

[0011] In a preferred embodiment of this invention, the elastic cushioning outer jacket includes a first elastic cushioning pad with a U-shaped structure, and a second elastic cushioning pad is provided at the upper end of the first elastic cushioning pad. The first elastic cushioning pad is made of highly elastic natural rubber, and the second elastic cushioning pad is made of high molecular polyurethane material.

[0012] In a preferred embodiment of this invention, the second elastic buffer pad is provided with an inclined V-shaped groove, and the V-shaped groove is set with the front lower than the back.

[0013] In a preferred embodiment of this invention, a blocking plate is inserted and installed on the front end of the rectangular plate, and the blocking plate is provided with a magnetic insertion post, and the rectangular plate is provided with a mounting hole adapted to the insertion post.

[0014] In a preferred embodiment of this invention, the front end of the elastic buffer strip is provided with a first through opening, and the corresponding position of the rectangular plate is provided with a second through opening.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] This utility model has a reasonable structure. It uses multiple sets of elastic buffer strips arranged in an isosceles trapezoidal shape to form a buffer bed surface to replace the buffer roller group to buffer the material. The buffer bed surface provides continuous and uniform support through large-area buffer strips, distributing the impact load to the entire contact surface. It uses surface contact instead of traditional point or line contact to form good buffering and effectively avoid overload. Moreover, this device itself has no easily damaged rotating parts such as bearings and rollers, which fundamentally eliminates the failure caused by bearing failure and cylinder deformation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Reference Figure 1-2 The device shown is a buffer for the material drop point of a belt conveyor, including multiple sets of I-shaped steel 1 arranged in rows and multiple sets of support plates 2. Each set of support plates 2 is installed on the corresponding I-shaped steel 1. The upper end of the support plate 2 is provided with a groove, and the groove is configured as an isosceles trapezoidal structure.

[0025] It also provides multiple sets of rectangular plates 3 with mounting grooves, and the multiple sets of rectangular plates 3 are arranged along the inner wall of the groove and fixedly connected to multiple support plates 2. When the mounting groove is detachable, a rectangular elastic buffer strip 4 is installed.

[0026] Multiple sets of elastic buffer strips 4 arranged in an isosceles trapezoid form a buffer bed surface to replace the buffer roller group for buffering the material. The buffer bed surface provides continuous and uniform support through large-area buffer strips, distributing the impact load to the entire contact surface. By using surface contact instead of traditional point or line contact, good buffering is formed and overload is effectively avoided.

[0027] Furthermore, this device itself has no easily damaged rotating parts such as bearings or rollers, which fundamentally eliminates the faults caused by bearing failure or cylinder deformation.

[0028] As a preferred embodiment of this example, Figure 4 As shown, the elastic buffer strip 4 includes a metal support base plate 405, an elastic buffer outer jacket, and multiple sets of buffer springs 404;

[0029] The elastic buffer sleeve is fixed in the inner cavity of the metal support base plate 405. The inner cavity of the rectangular plate 3 is provided with slots that fit at both ends of the metal support base plate 405. The top of the inner cavity of the elastic buffer sleeve is fixed with a metal support top plate 403. The metal support top plate 403 and the metal support base plate 405 are connected by multiple sets of buffer springs 404.

[0030] The buffering effect on the material can be improved by combining the buffer spring 404 (which resists low-frequency large-amplitude impacts through elastic deformation and also limits excessive deformation of the elastic buffer jacket) and the elastic buffer jacket (which is used for instantaneous collision between the material and the metal support top plate 403).

[0031] It should be noted that an elastic pad (made of rubber material) can be wrapped around the outside of the metal support base plate 405 for cushioning.

[0032] As a preferred embodiment of this example, Figure 4 As shown, the elastic cushioning jacket includes a first elastic cushioning pad 402 with a U-shaped structure, and a second elastic cushioning pad 401 is provided at the upper end of the first elastic cushioning pad 402. The first elastic cushioning pad 402 is made of highly elastic natural rubber, and the second elastic cushioning pad 401 is made of high-molecular polyurethane material.

[0033] The second elastic buffer pad 401, made of high-molecular polyurethane material, has a low coefficient of friction and high wear resistance, reducing frictional damage when in contact with materials and improving the service life of components; the first elastic buffer pad 402, made of high-elasticity natural rubber, has a good buffering effect and can form a good buffer for materials.

[0034] As a preferred embodiment of this example, Figure 2 As shown, the second elastic buffer pad 401 has an inclined V-shaped groove 11, and the V-shaped groove 11 is set with the front lower and the back higher.

[0035] The design of the V-groove 11 increases the effective deformation space and improves the buffering effect. The V-groove 11 is set with a lower front and a higher back. Its purpose is to allow dust or particles that fall to the bottom of the V-groove 11 to be discharged outward along its inclined surface (when the elastic buffer strip 4 is impacted), keeping the bottom of the inner cavity of the V-groove 11 clean and avoiding affecting the buffering.

[0036] It should be noted that the lowest end of the V-groove 11 is located above the rectangular plate 3.

[0037] As a preferred embodiment of this example, Figure 3 As shown, a blocking plate 6 is inserted and installed on the front end of the rectangular plate 3, and a magnetic insertion post 7 is provided on the blocking plate 6. The rectangular plate 3 is provided with an installation hole 8 that is compatible with the insertion post 7.

[0038] The plug-in post 7 is inserted into the mounting hole 8, and the magnetic properties of the plug-in post 7 are used to magnetically attract and fix the rectangular plate 3, which facilitates the disassembly and installation of the blocking plate 6 and the rectangular plate 3.

[0039] It should be noted that a material discharge opening 5 can be provided at the bottom of the inner cavity of the rectangular plate 3, which is located away from the blocking plate 6. When the insertion end of the elastic buffer strip 4 is inserted into the mounting groove of the rectangular plate 3, the movement of the elastic buffer strip 4 can push the dust or particles in the mounting groove to the material discharge opening 5 and remove them. This can achieve cleaning of the mounting groove during installation and prevent dust or particles or the installation or buffering of the elastic buffer strip 4 from affecting the installation.

[0040] As a preferred embodiment of this example, Figure 2 and Figure 3 As shown, the front end of the elastic buffer strip 4 is provided with a first through opening 9, and the corresponding position of the rectangular plate 3 is provided with a second through opening 10.

[0041] When removing the elastic buffer strip 4, you can insert your fingers into the first through opening 9 and the second through opening 10 to pull out the elastic buffer strip 4, which makes it easy to disassemble the elastic buffer strip 4.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
