Description

Technical Field

[0001] The utility model relates to a vibrating screening conveyor belt. Background Art

[0002] The bucket elevator conveyor belt is a commonly used vertical conveying equipment in the material conveying system, mainly used for conveying bulk materials from a low place to a high place. The existing bucket elevator conveyor belt evenly installs hoppers on the conveyor belt, and uses the movement of the belt conveyor to gradually lift the materials to the required height, and is widely used in industrial production.

[0003] The working process of the existing bucket elevator conveyor belt is as follows: after the materials enter from the feeding port, they fall into the moving hoppers; as the conveyor belt runs, the hoppers loaded with materials move upward along the rack track; when the hoppers reach the top, under the action of centrifugal force and gravity, the materials are thrown out of the hoppers and fall into the collecting device or the subsequent conveying equipment through the discharge chute. This conveying method has a simple structure, reliable operation, and strong conveying capacity.

[0004] However, the existing bucket elevator conveyor belt has obvious technical limitations. The most important problem is that its function is too single, and it can only complete the vertical conveying task of materials, and cannot screen the materials. In actual production, the conveyed materials are often mixed with a large amount of impurities such as sand and gravel. If these impurities cannot be removed in time, it will affect the normal progress of the subsequent production processes.

[0005] The current solution is to screen the materials through a special vibrating screen after the bucket elevator conveyor belt finishes conveying. This step-by-step treatment method not only increases the equipment investment, but also occupies more production sites; at the same time, multiple transfers also increase the risk of material loss and dust pollution, and reduce the production efficiency.

[0006] In addition, the traditional treatment method requires a transfer link between conveying and screening, which not only prolongs the material treatment time, but also increases manual operation and energy consumption. Especially in a continuous production line, this segmented treatment method will affect the overall production rhythm and cause poor connection of processes.

[0007] Therefore, it is of great practical significance to develop a vibrating screening conveyor belt that can simultaneously realize the material screening function during the conveying process. This equipment needs to organically combine the conveying and screening functions, not only ensure the conveying efficiency, but also effectively separate impurities such as sand and gravel, so as to improve the production efficiency and reduce the operation cost. Summary of the Utility Model

[0008] The purpose of the utility model is to provide a vibrating screening conveyor belt. This vibrating screening conveyor belt has the characteristics of improving production efficiency and reducing operation cost.

[0009] The above technical object of the present utility model is achieved through the following technical solutions:

[0010] A vibrating screening conveyor belt, comprising: a bracket; an inclined conveyor belt disposed on the bracket; a motor disposed at the end of the conveyor belt; a plurality of hoppers arranged around the conveyor belt; a hinge seat I disposed at the bottom of the hopper; a hinge seat II disposed on the conveyor belt, the hinge seat I and the hinge seat II are hinged to each other, and a spring is disposed at the hinge; a plurality of screening holes are disposed in the middle of the hopper; two fixing frames are arranged in sequence on the front of the conveyor belt; a contact rod disposed between the two fixing frames.

[0011] The present utility model is further configured such that: the spring has a high elastic coefficient.

[0012] The present utility model is further configured such that: the contact rod is fixedly arranged.

[0013] The present utility model is further configured such that: the fixing frame is fixedly arranged on the conveyor belt.

[0014] The present utility model is further configured such that: the hopper can rotate 1 - 5° under the action of the spring.

[0015] The present utility model is further configured such that: the hopper can rotate 15° under the action of the contact rod.

[0016] The present utility model is further configured such that: the hopper can reset under the action of the spring.

[0017] The present utility model is further configured such that: the hopper can achieve multiple vibrations by contacting a plurality of contact rods.

[0018] The present utility model is further configured such that: the contact rod is used to apply pressure to the hopper to cause vibration.

[0019] In summary, the present utility model has the following beneficial effects:

[0020] In this application, by integrating the material screening function on the basis of the traditional bucket elevator conveyor belt, the integrated processing of material transportation and sand and gravel screening is realized. Through the hinge structure and spring assembly at the bottom of the hopper, and in cooperation with the fixed contact rod on the conveyor belt, the hopper generates controlled vibrations during the upward transportation process. When the hopper contacts the contact rod, it generates reciprocating vibrations under the action of the spring, and the sand and gravel impurities in the material are screened out through the screening holes in the middle of the hopper, realizing the synchronous screening of the material.

[0021] It has changed the traditional step-by-step processing method that requires transportation first and then screening, eliminating the separate vibrating screening equipment and transfer links, significantly reducing equipment investment and site occupation. At the same time, due to the reduction of the number of material transfers, material loss and dust pollution are effectively reduced, and production efficiency is improved. The high elastic coefficient of the spring ensures the stability of the hopper during vibration, while the setting of multiple abutting rods ensures a sufficient screening effect. The controlled rotation angles of the hopper at 1-5° and 15°, combined with the reset function of the spring, form a stable vibration frequency, which not only ensures the screening effect but also does not affect the normal transportation of materials.

In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" 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 a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] As Figure 1 shown, a vibrating screening conveyor belt includes a bracket 1. An obliquely arranged conveyor belt 2 is provided on the bracket 1. A motor 10 is arranged at the end of the conveyor belt 2 to drive the conveyor belt 2 to work. The above is the prior art and will not be elaborated here.

[0030] The core technical solution of this application is as follows:

[0031] As Figure 1 、 Figure 2 shown, for the purpose of screening sand and gravel in the material during transportation. A plurality of hoppers 3 arranged around the conveyor belt 2 are provided on the conveyor belt 2. A hinge seat one 4 is connected to the bottom of the hopper 3. A hinge seat two 5 is provided on the conveyor belt 2. The hinge seat one 4 and the hinge seat two 5 are hinged to each other, and a spring 6 is provided at the hinge. The spring 6 has a high elastic coefficient and can only be bent under a large acting force, causing the hopper 3 to rotate.

[0032] Among them, a plurality of screening holes 7 are provided in the middle of the hopper 3. When the hopper 3 vibrates, the sand and gravel in the material can be screened out through the screening holes 7.

[0033] On the front side of the conveyor belt 2, two fixing brackets 8 are arranged in sequence. The fixing brackets 8 are fixedly arranged on the conveyor belt 2, and an abutting rod 9 is arranged between the two fixing brackets 8. The abutting rod 9 is fixedly arranged. When the conveyor belt works under the action of the motor 10, the conveyor belt 2 drives the hopper 3 to move. When the hopper 3 reaches the bottom, materials are input into the hopper 3. At this time, the hopper 3 contains materials and sand and gravel. Under the action of the spring 6 with a high elastic coefficient, the hopper 3 rotates by 1-5°. When the hopper 3 continues to move under the action of the conveyor belt 2, the hopper 3 comes into contact with the abutting rod 9. The abutting rod 9 exerts a pressure on the hopper 3, causing the hopper 3 to rotate by 15°. The hopper 3 can smoothly disengage from the abutting rod 9 and continue to move. At this time, the spring 6 causes the hopper 3 to reset, thereby causing the hopper 3 to vibrate back and forth once, and initially screening out the sand and gravel in the materials. The hopper 3 continues to move to the positions of multiple subsequent abutting rods 9, achieving the purpose of vibrating the hopper 3 multiple times, and further screening out the sand and gravel in the materials.

[0034] In this application, by integrating the material screening function on the basis of the traditional bucket elevator conveyor belt, the integrated processing of material transportation and sand and gravel screening is realized. Through the hinge structure at the bottom of the hopper 3 and the spring 6 assembly, and in cooperation with the abutting rod 9 fixed on the conveyor belt 2, the hopper 3 generates controlled vibrations during the ascending transportation process. When the hopper 3 comes into contact with the abutting rod 9, reciprocating vibrations are generated under the action of the spring 6, and the sand and gravel impurities in the materials are screened out through the screening holes 7 in the middle of the hopper 3, realizing the synchronous screening of the materials.

[0035] It changes the traditional step-by-step processing method that requires transportation first and then screening, eliminates the separate vibration screening equipment and transfer links, significantly reduces the equipment investment and site occupation. At the same time, due to the reduction of the material transfer times, the material loss and dust pollution are effectively reduced, and the production efficiency is improved. The high elastic coefficient of the spring 6 ensures the stability of the hopper 3 during the vibration process, and the setting of multiple abutting rods 9 ensures a sufficient screening effect. The controlled rotation angles of 1-5° and 15° of the hopper 3, combined with the reset function of the spring 6, form a stable vibration frequency, which not only ensures the screening effect but also does not affect the normal transportation of the materials.

[0036] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
