Description

Technical Field

[0001] This application belongs to the field of belt conveyor technology, and specifically relates to a belt conveyor device. Background Technology

[0002] Belt conveyors are mechanical devices used for the continuous transport of bulk materials or packaged goods, and are widely used in mining, metallurgy, chemical industry, ports, power, building materials, grain, and many other industries. The basic principle of belt conveyors is that a motor drives rollers to achieve continuous operation, and the rollers drive the belt to move continuously, transporting materials from one location to another.

[0003] During the transfer of bagged cement, the vibration and friction during handling, stacking and conveying can easily cause the cement bags to break, resulting in cement powder spilling and adhering to the belt. Since cement is prone to solidification when it gets damp, the solidified cement will make the surface of the belt uneven, increasing the friction with the idlers and rollers during operation, which will cause the rubber layer to wear and tear easily, reducing the service life of the belt. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies, this application provides a belt conveyor device, which aims to solve the technical problem that the solidified cement will cause the belt surface to be uneven, thereby reducing the service life of the belt.

[0005] To achieve the above objectives, this application provides a belt conveyor device, which includes a belt conveyor unit, a first pressure roller mechanism, and two first cleaning components. The belt conveyor unit has a belt body that can rotate up and down for transmission. The first pressure roller mechanism is disposed on the belt conveyor unit and can press down on the lower rotating section of the belt body, so that two vertical cleaning sections are formed on the lower rotating section. The two first cleaning components are disposed at a distance from the first pressure roller mechanism and are respectively disposed in correspondence with the two vertical cleaning sections.

[0006] In this embodiment of the application, the belt conveyor further includes a liquid storage tank and a second pressure roller mechanism. The liquid storage tank is located below the first pressure roller mechanism. The second pressure roller mechanism is spaced apart from the first pressure roller mechanism on the belt conveyor and can press down the lower rotating section of the belt body. Both the first pressure roller mechanism and the second pressure roller mechanism include a lifting drive and a pressure roller assembly. The driving end of the lifting drive is connected to the pressure roller assembly. The lifting drive is used to drive the pressure roller assembly to move the belt body closer to or away from the liquid storage tank.

[0007] In this embodiment of the application, the belt conveyor further includes two second cleaning components, which are arranged at intervals from the second pressure roller mechanism and correspond one-to-one with the two vertical cleaning sections on both sides of the second pressure roller mechanism.

[0008] In this embodiment, the belt conveyor further includes a frame; both the first pressure roller mechanism and the second pressure roller mechanism further include a support rod and a guide assembly. The guide assembly includes a first sliding rod and a second sliding rod that are slidably connected. The first sliding rod is connected to the support rod, the second sliding rod is connected to the pressure roller assembly, the support rod is connected to the frame, and the support rod is connected to the drive component.

[0009] In this embodiment of the application, the first sliding rod is provided with a sliding groove and a limiting groove. The sliding groove has an opening, and the limiting groove is located on the side wall of the sliding groove. The second sliding rod is slidably located in the sliding groove, and a limiting block is provided on the second sliding rod and is slidably disposed in the limiting groove. The limiting block is used to abut against both ends of the limiting groove.

[0010] In this embodiment of the application, the pressure roller assembly includes a pressure roller body and a mounting base. The mounting base includes a mounting plate and two mounting arms that are respectively connected to both ends of the mounting plate. The mounting plate is connected to the driving end of the lifting drive component, and the pressure roller body is rotatably connected between the two mounting arms.

[0011] In this embodiment, the first cleaning component includes a cleaning brush, a connecting seat, and an elastic element. The cleaning brush is slidably connected to the connecting seat, the elastic element extends along the distribution direction of the two vertical cleaning sections, and the elastic element is connected between the connecting seat and the cleaning brush. The connecting seat is connected to the first pressure roller mechanism.

[0012] In this embodiment, the connecting seat includes a connecting arm and a guide rail connected together, and the connecting arm is connected to the first pressure roller mechanism; the cleaning brush includes a brush body and a sliding part connected together, the sliding part is slidably sleeved outside the guide rail, and an elastic element is connected between the sliding part and the connecting arm.

[0013] In this embodiment, a first connecting plate is provided on the connecting arm, and a second connecting plate is formed by extending the sliding part away from the brush body outward. An elastic element is connected between the first connecting plate and the second connecting plate.

[0014] In this embodiment of the application, the belt conveyor also includes a guide wheel assembly, which includes two guide wheels connected to the frame, and the two guide wheels are respectively set for two vertical cleaning sections.

[0015] Through the above technical solutions, the belt conveyor equipment provided in this application embodiment has the following beneficial effects:

[0016] The belt conveyor is equipped with a belt body that can rotate up and down. The rotation of the belt body drives the material to move, thereby realizing the material conveying. A first pressure roller mechanism is installed on the belt conveyor and is located between the upper and lower rotating sections of the belt body. The first pressure roller mechanism can press down on the lower rotating section of the belt body, so that two vertical cleaning sections are formed on the lower rotating section. Two first cleaning components are respectively arranged one-to-one with the two vertical cleaning sections.

[0017] By controlling the rotation of the belt conveyor, the first cleaning component rubs against the vertical cleaning section, scraping off the cement that has hardened on the belt. This allows the belt to be cleaned simply by rotating. Furthermore, two first cleaning components are positioned one-to-one with two vertical cleaning sections, enabling the belt to be cleaned twice, resulting in a more effective cleaning.

[0043] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0044] The belt conveyor of this application is described below with reference to the accompanying drawings.

[0045] like Figures 1 to 5 As shown, this application provides a belt conveyor device, which includes a belt conveyor 10, a first pressure roller mechanism 20, and two first cleaning components 30. The belt conveyor 10 has a belt body 11 that can rotate up and down for transmission. The first pressure roller mechanism 20 is disposed on the belt conveyor 10 and can press down the lower rotating section 111 of the belt body 11, so that two vertical cleaning sections 112 are formed on the lower rotating section 111. The two first cleaning components 30 are disposed at a distance from the first pressure roller mechanism 20 and are respectively disposed one-to-one with the two vertical cleaning sections 112.

[0046] The belt conveyor 10 is equipped with a belt body 11, which can rotate up and down. The rotation of the belt body 11 drives the material to move, thereby realizing the material conveying. The first pressure roller mechanism 20 is provided on the belt conveyor 10, and the first pressure roller mechanism 20 is located between the upper rotating section and the lower rotating section 111 of the belt body 11. The first pressure roller mechanism 20 can press down on the lower rotating section 111 of the belt body 11, so that two vertical cleaning sections 112 are formed on the lower rotating section 111. Two first cleaning components 30 are respectively arranged in a one-to-one correspondence with the two vertical cleaning sections 112.

[0047] By controlling the rotation of the belt conveyor 11, the first cleaning component 30 rubs against the vertical cleaning section 112, which scrapes and removes the cement that has hardened on the belt conveyor 11. This allows the belt conveyor 11 to be cleaned simply by rotating. Furthermore, two first cleaning components 30 are respectively positioned one-to-one with two vertical cleaning sections 112, allowing for two separate cleaning processes on the belt conveyor 11, resulting in a better cleaning effect.

[0048] It is understandable that, in order for the first pressure roller mechanism 20 to press down the lower rotating section 111 of the belt body 11 to form two vertical cleaning sections 112, the belt body 11 of the belt conveyor device 10 of this application is longer than the belt body 11 of the conventional belt conveyor device 10.

[0049] In the embodiments of this application, please refer to Figures 1 to 4 The belt conveyor also includes a liquid storage tank 40 and a second pressure roller mechanism 50. The liquid storage tank 40 is located below the first pressure roller mechanism 20. The second pressure roller mechanism 50 is spaced apart from the first pressure roller mechanism 20 on the belt conveyor 10 and can press down the lower rotating section 111 of the belt body 11. Both the first pressure roller mechanism 20 and the second pressure roller mechanism 50 include a lifting drive component 21 and a pressure roller assembly 22. The driving end of the lifting drive component 21 is connected to the pressure roller assembly 22. The lifting drive component 21 is used to drive the pressure roller assembly 22 to move the belt body 11 closer to or away from the liquid storage tank 40.

[0050] A liquid storage tank 40 is located below the first pressure roller mechanism 20. The liquid storage tank 40 contains cleaning fluid, which allows for more thorough cleaning of the belt conveyor 11. A second pressure roller mechanism 50 is spaced apart from the first pressure roller mechanism 20 on the belt conveyor 10 in a left-right direction. The second pressure roller mechanism 50 can press down on the lower rotating section 111 of the belt conveyor 11. The driving end of the lifting drive component 21 is connected to the pressure roller assembly 22, and the lifting drive component 21 can drive the pressure roller assembly 22 to move the belt conveyor 11 closer to or away from the liquid storage tank 40.

[0051] When the belt body 11 needs cleaning, the lifting drive 21 of the second pressure roller mechanism 50 drives the pressure roller assembly 22 away from the liquid storage tank 40. At the same time, the lifting drive 21 of the first pressure roller mechanism 20 drives the pressure roller assembly 22 closer to the liquid storage tank 40, so that the pressure roller assembly 22 of the first pressure roller mechanism 20 can press the lower rotating section 111 down into the liquid storage tank 40. With the help of the cleaning fluid in the liquid storage tank 40, the belt body 11 can be cleaned more thoroughly.

[0052] It is understandable that the structure of the second pressure roller mechanism 50 can be the same as that of the first pressure roller mechanism 20.

[0053] In the embodiments of this application, please refer to Figures 1 to 4 The belt conveyor also includes two second cleaning components 60, which are spaced apart from the second pressure roller mechanism 50 and correspond one-to-one with the two vertical cleaning sections 112 on both sides of the second pressure roller mechanism 50.

[0054] Two second cleaning components 60 are located on the left and right sides of the second pressure roller mechanism 50, respectively, and the two second cleaning components 60 are respectively configured to correspond one-to-one with the two vertical cleaning sections 112 on both sides of the second pressure roller mechanism 50. By setting two second cleaning components 60, pre-cleaning can be performed before the belt body 11 moves to the first pressure roller mechanism 20, so that the cleaning effect of the belt conveyor is better.

[0055] It is understandable that the structure of the second cleaning component 60 can be the same as that of the first cleaning component 30.

[0056] In the embodiments of this application, please refer to Figure 5 The belt conveyor 10 also includes a frame 12; the first pressure roller mechanism 20 and the second pressure roller mechanism 50 both include a support rod 23 and a guide assembly 24. The support rod 23 is connected to the frame 12, and the guide assembly 24 includes a first sliding rod 241 and a second sliding rod 242 that are slidably connected. The first sliding rod 241 is connected to the support rod 23, the second sliding rod 242 is connected to the pressure roller assembly 22, and the support rod 23 is connected to the drive component.

[0057] Support rod 23 is connected to frame 12, thereby enabling the installation and fixation of the first pressure roller mechanism 20 and the second pressure roller mechanism 50. Both the first sliding rod 241 and the second sliding rod 242 extend vertically. The first sliding rod 241 is connected to support rod 23, thereby enabling the installation and fixation of guide assembly 24. The second sliding rod 242 is connected to pressure roller assembly 22, and can slide vertically relative to the first sliding rod 241. During the process of lifting drive component 21 driving pressure roller assembly 22 closer to or further away from liquid storage tank 40, the second sliding rod 242 slides vertically relative to the first sliding rod 241. By setting the first sliding rod 241 and the second sliding rod 242 for guidance, the process of lifting drive component 21 driving pressure roller assembly 22 to rise and fall is made more stable and reliable.

[0058] Specifically, the lifting drive component 21 can be an electric actuator, a cylinder, a motor, or other drive structure.

[0059] In the embodiments of this application, please refer to Figure 5 The first sliding rod 241 has a sliding groove 2411 and a limiting groove 2412. The sliding groove 2411 has an opening, and the limiting groove 2412 is located on the side wall of the sliding groove 2411. The second sliding rod 242 is slidably located in the sliding groove 2411, and a limiting block 2421 is slidably provided on the second sliding rod 242 in the limiting groove 2412. The limiting block 2421 is used to abut against both ends of the limiting groove 2412.

[0060] The first sliding rod 241 has a groove 2411 extending vertically and a limiting groove 2412. The lower end of the groove 2411 has an opening, and the limiting groove 2412 is formed on the side wall of the groove 2411. The second sliding rod 242 is slidably located within the groove 2411 and can slide relative to the groove wall of the groove 2411. Furthermore, the second sliding rod 242 is provided with an outwardly protruding limiting block 2421, which is slidably disposed within the limiting groove 2412 and abuts against both ends of the limiting groove 2412. By setting the limiting block 2421 to cooperate with the limiting groove 2412, the sliding stroke of the second sliding rod 242 relative to the first sliding rod 241 is limited. Moreover, the limiting block 2421 can prevent the second sliding rod 242 from detaching from the first sliding rod 241, making the sliding process of the second sliding rod 242 more reasonable and reliable.

[0061] In the embodiments of this application, please refer to Figure 5 The pressure roller assembly 22 includes a pressure roller body 221 and a mounting base 222. The mounting base 222 includes a mounting plate 223 and two mounting arms 224 respectively connected to both ends of the mounting plate 223. The mounting plate 223 is connected to the driving end of the lifting drive component 21. The pressure roller body 221 is rotatably connected between the two mounting arms 224.

[0062] Mounting plate 223 extends in the front-to-back direction, and two mounting arms 224 are respectively connected to the front and rear ends of mounting plate 223. Mounting plate 223 is connected to the driving end of lifting drive component 21 so that lifting drive component 21 can drive pressure roller assembly 22 to rise and fall. Pressure roller body 221 extends in the front-to-back direction and is rotatably connected between two mounting arms 224. Pressure roller body 221 can rotate, which facilitates belt body 11 to rotate around pressure roller body 221.

[0063] In the embodiments of this application, please refer to Figure 4 and Figure 5 The first cleaning component 30 includes a cleaning brush 31, a connecting seat 32, and an elastic element 33. The cleaning brush 31 is slidably connected to the connecting seat 32. The elastic element 33 extends along the distribution direction of the two vertical cleaning sections 112 and is connected between the connecting seat 32 and the cleaning brush 31. The connecting seat 32 is connected to the first pressure roller mechanism 20.

[0064] The connecting seat 32 is connected to the first pressure roller mechanism 20 to achieve the installation and fixation of the connecting seat 32. The cleaning brush 31 is slidably connected to the connecting seat 32, and the cleaning brush 31 can slide relative to the connecting seat 32 in the left-right direction to move closer to or away from the belt body 11. The elastic member 33 extends in the left-right direction, and one end of the elastic member 33 is connected to the cleaning brush 31, and the other end of the elastic member 33 is connected to the connecting seat 32. Figure 4 and Figure 5 As shown, the elastic force of the elastic element 33 causes the cleaning brush 31 to slide relative to the connecting seat 32 in a direction close to the vertical cleaning section 112, so that the cleaning brush 31 can abut against the vertical cleaning section 112, thereby making the cleaning assembly more effective at cleaning the belt body 11.

[0065] In the embodiments of this application, please refer to Figure 4 and Figure 5 The connecting seat 32 includes a connecting arm 321 and a guide rail 322 connected together. The connecting arm 321 is connected to the first pressure roller mechanism 20. The cleaning brush 31 includes a brush body 311 and a sliding part 312 connected together. The sliding part 312 is slidably sleeved on the outside of the guide rail 322. The elastic member 33 is connected between the sliding part 312 and the connecting arm 321.

[0066] One end of the connecting arm 321 is connected to the guide rail 322, which extends in the left-right direction. The other end of the connecting arm 321 is connected to the first pressure roller mechanism 20. The brush body 311 extends in the front-back direction, and the sliding part 312 extends in the left-right direction. The sliding part 312 is slidably sleeved on the outside of the guide rail 322. Through the cooperation between the sliding part 312 and the guide rail 322, the cleaning brush 31 can slide stably and reliably relative to the connecting seat 32 in the left-right direction, improving the stability of the sliding process.

[0067] Specifically, one of the sliding part 312 and the guide rail 322 may be provided with a sliding protrusion extending in the left and right direction, and the other may be provided with a sliding groove extending in the left and right direction. The sliding protrusion is slidably disposed in the sliding groove. The connection between the sliding part 312 and the guide rail 322 is made more stable by the cooperation between the sliding protrusion and the sliding groove, thereby further improving the stability and reliability of the sliding process.

[0068] like Figure 5 As shown, there can be two connecting seats 32 and two elastic members 33. Correspondingly, there can also be two sliding parts 312 of the cleaning brush 31. The elastic member 33 is connected between the corresponding connecting arm 321 and the sliding part 312.

[0069] In the embodiments of this application, please refer to Figure 4 and Figure 5 A first connecting plate 323 is provided on the connecting arm 321, and a second connecting plate 313 is formed by extending the sliding part 312 away from the brush body 311. An elastic member 33 is connected between the first connecting plate 323 and the second connecting plate 313.

[0070] The first connecting plate 323 is disposed on the connecting arm 321, and the second connecting plate 313 is disposed on the sliding part 312. One end of the elastic member 33 is connected to the first connecting plate 323, and the other end of the elastic member 33 is connected to the second connecting plate 313. The installation of the elastic member 33 is achieved by setting the first connecting plate 323 and the second connecting plate 313, so that the elastic member 33 can stably deform elastically in the left and right directions.

[0071] Furthermore, the second connecting plate 313 is formed by extending the sliding part 312 outward, and a stop step surface is formed between the guide rail 322 and the connecting arm 321. The stop step surface is used to stop the second connecting plate 313 and prevent the second connecting plate 313 from excessively compressing the elastic member 33, which would reduce the service life of the elastic member 33.

[0072] Specifically, the elastic element 33 can be a spring, an elastic sleeve, or other elastic structure.

[0073] In the embodiments of this application, please refer to Figure 4 The belt conveyor also includes a set of guide wheels 70, which includes two guide wheels 70 connected to the belt conveyor 10. The two guide wheels 70 are respectively set for two vertical cleaning sections 112. By setting the guide wheels 70, the belt body 11 is guided, so that the belt body 11 can form vertical cleaning sections 112 extending in the vertical direction.
