[0034] 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.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0038] In related technologies, it is necessary to constantly monitor whether the belt conveyor 100 experiences a return carrying of material. If the belt conveyor 100 experiences a return carrying of material, it needs to be cleaned manually in a timely manner, which is labor-intensive.

[0039] This application provides a conveying device 1000, which can at least partially solve the technical problem that manual cleaning is required when the belt conveyor 100 experiences material return during the return stroke.

[0040] This application is described below with reference to the accompanying drawings and specific embodiments:

[0041] like Figure 1 and Figure 2As shown, the conveying device 1000 includes a belt conveyor 100 and a clearing mechanism 200. The belt conveyor 100 includes a conveyor frame 110 and a conveyor belt 120. The clearing mechanism 200 includes an adjusting component 210, a support base 220, and a scraper 230. The adjusting component 210 is mounted on the conveyor frame 110; the support base 220 is mounted on the adjusting component 210; the scraper 230 is mounted on the support base 220 and contacts the upper surface 121a of the return section 121 of the conveyor belt 120. Along the width direction of the conveyor belt 120, both ends of the scraper 230 extend out of the conveyor belt 120.

[0042] In the attached diagram, W represents the running direction of the conveyor belt 120, X represents the length direction of the conveyor belt 120, Y represents the width direction of the conveyor belt 120, and Z represents the height direction.

[0043] The belt conveyor 100 includes a conveyor frame 110 and a conveyor belt 120. It may also include rollers 130, with two or more rollers 130 on which the conveyor belt 120 is fitted. The belt conveyor 100 may also include a drive mechanism that drives the rollers 130 to rotate, thereby causing the conveyor belt 120 to rotate and enabling it to transport material 10. The belt conveyor 100 may also include idler assemblies that support the conveyor belt 120 and the material 10, reducing the running resistance of the conveyor belt 120. The conveyor frame 110 supports components such as the rollers 130, the drive mechanism, and the idler assemblies. The structure of the belt conveyor 100 is diverse and known to those skilled in the art, and is not limited herein.

[0044] like Figure 1 As shown, the conveyor belt 120 includes a conveying section 122 and a return section 121, with the conveying section 122 located above the return section 121. Material 10 is placed above the conveying section 122, which transports the material 10 from the loading end to the unloading end. The return section 121 creates a closed loop for the conveyor belt 120, enabling continuous conveying. The return section 121 refers to the section where the conveyor belt 120 returns to the loading end after the conveyor belt 100 has completed its material conveying task.

[0045] The adjusting component 210 of the obstacle clearing mechanism 200 is mounted on the conveyor frame 110. The adjusting component 210 and the conveyor frame 110 can be connected by bolts, snap-fit, welding, or other methods, which are not limited in this application. The support base 220 is mounted on the adjusting component 210. The support base 220 and the adjusting component 210 can be connected by bolts, snap-fit, welding, or other methods, which are not limited in this application. The scraper 230 is mounted on the support base 220. The scraper 230 and the support base 220 can be connected by bolts, snap-fit, welding, adhesive, or other methods, which are not limited in this application.

[0046] The scraper 230 contacts the upper surface 121a of the return section 121, and both ends of the scraper 230 extend beyond the conveyor belt 120. This ensures that when the belt conveyor 100 experiences a return carrying phenomenon, the material 10 on the upper surface 121a can be intercepted by the scraper 230 and fall off, preventing the material 10 from being rolled into the roller 130 behind the scraper 230. Figure 1 The right-side roller 130 in the middle of the belt 120 may experience deviation or even tearing, thus ensuring the continuous and stable operation of the belt conveyor 100.

[0047] When the belt conveyor 100 in the conveying device 1000 provided in this application experiences a return stroke with material, the scraper 230 of the obstacle clearing mechanism 200 can automatically clean the material 10 located on the upper surface 121a of the return section 121 without manual cleaning. This avoids the material 10 from being rolled into the roller 130 behind the scraper 230, preventing the conveyor belt 120 from running off-center or even tearing. This reduces the labor intensity of manual labor, ensures the efficiency of material 10 transmission, and ensures the continuous and stable operation of the belt conveyor 100.

[0048] like Figure 2 and Figure 4 As shown, in some embodiments, the obstacle clearing mechanism 200 further includes a pressure plate 240 and a connector 250, with a scraper 230 disposed between the pressure plate 240 and the support base 220; the pressure plate 240, the scraper 230, and the support base 220 are connected by the connector 250.

[0049] The scraper 230 is located between the pressure plate 240 and the support base 220. After the connector 250 connects the pressure plate 240, the scraper 230, and the support base 220, the pressure plate 240 and the support base 220 clamp the scraper 230, thus fixing the scraper 230. The pressure plate 240 allows the clamping force of the connector 250 to be evenly distributed throughout the scraper 230, which helps improve the stability of the scraper 230. The connector 250 can be a bolt, screw, rivet, etc., and is not limited thereto in this application.

[0050] like Figure 4 As shown, in some embodiments, the connector 250 includes a bolt 251 and a nut 252. The thread 2511 of the bolt 251 passes through the pressure plate 240, the scraper 230, and the support seat 220. The nut 252 is threadedly connected to the thread 2511, and the pressure plate 240, the scraper 230, and the support seat 220 are all located between the nut 252 and the head 2512 of the bolt 251.

[0051] It is easy to understand that the pressure plate 240, scraper 230, and support base 220 are all provided with through holes to allow the screw 2511 to pass through them. A nut 252 is threaded onto the screw 2511. After tightening the nut 252, the nut 252 and the head 2512 clamp the pressure plate 240, scraper 230, and support base 220 together, thus fixing them in place. The scraper 230 contacts the conveyor belt 120 and will wear down. In these embodiments, the pressure plate 240, scraper 230, and support base 220 are connected by bolts 251 and nuts 252, facilitating the disassembly and replacement of the scraper 230 and simplifying the use of the conveyor device 1000.

[0052] In some embodiments, multiple connectors 250 are spaced apart along the width direction of the conveyor belt 120. The arrangement of multiple connectors 250 ensures the robust connection between the pressure plate 240, the scraper 230, and the support 220.

[0053] In some embodiments, the support 220 is movably connected to the adjustment assembly 210 along the height direction.

[0054] In other words, the support base 220 can move up and down and be fixed at different heights. The scraper 230 is mounted on the support base 220, and adjusting the height of the support base 220 can change the height of the scraper 230. With this design, when the scraper 230 wears down and is no longer in contact with the conveyor belt 120, the support base 220 can be moved down, causing the scraper 230 to move down as well, so that the scraper 230 can re-engage with the conveyor belt 120, thus ensuring the cleaning effect of the scraper 230.

[0055] The support base 220 can be movably connected to the adjusting component 210 along the height direction in various ways. For example, multiple holes can be spaced apart along the height direction on the support base 220, and one hole can be opened on the adjusting component 210, with pins inserted into both holes. With this design, when the height of the support base 220 needs to be adjusted, the pins are pulled out from the two holes, the height of the support base 220 is moved so that the corresponding height hole on the support base 220 aligns with the hole on the adjusting component 210, and the pins are then reinserted, thus movably connecting the support base 220 to the adjusting component 210. Alternatively, multiple snap-fit ​​connectors can be spaced apart along the height direction on the support base 220, and a snap-fit ​​groove can be opened on the adjusting component 210. When different snap-fit ​​connectors engage with the snap-fit ​​groove, the height of the support base 220 will be different, thereby adjusting the height of the support base 220 and movably connecting it to the adjusting component 210.

[0056] like Figure 3 and Figure 5As shown, in some embodiments, the support base 220 has a clearance through hole 220a, and the adjusting assembly 210 includes a lead screw 211, a first nut 212, and a second nut 213. The lead screw 211 is arranged along the height direction and is fixedly connected to the conveyor frame 110, passing through the clearance through hole 220a. The first nut 212 and the second nut 213 are both threaded to the lead screw 211 and are located on both sides of the support base 220, respectively.

[0057] With this design, when both the first nut 212 and the second nut 213 are tightened, they clamp the support seat 220, thus fixing the support seat 220 and the adjusting component 210. When the height of the support seat 220 needs to be adjusted, the first nut 212 and the second nut 213 are loosened and then screwed to a certain height. The height of the support seat 220 is then adjusted, and the first nut 212 and the second nut 213 are tightened again to clamp the support seat 220, fixing it at the adjusted height. This allows the support seat 220 to be movably connected to the adjusting component 210. The first nut 212 and the second nut 213 can move steplessly on the lead screw 211, allowing the height of the support seat 220 to be continuously adjusted within a certain range. This makes the height of the support seat 220 more flexible and convenient for users to use the conveying device 100.

[0058] The lead screw 211 and the conveyor frame 110 can be fixedly connected by welding, bolting, snap-fitting, etc., and this application does not limit the connection.

[0059] In some embodiments, a plurality of adjusting components 210 are provided at intervals along the width direction of the conveyor belt 120. The arrangement of the plurality of adjusting components 210 helps to improve the stability of the support 220, thereby ensuring the stability of the scraper 230.

[0060] like Figure 2 and Figure 4 As shown, in some embodiments, the scraper 230 includes a first scraper 231 and a second scraper 232, with one end of the first scraper 231 and one end of the second scraper 232 connected together; along the running direction of the conveyor belt 120, the distance between the first scraper 231 and the second scraper 232 gradually increases; both the first scraper 231 and the second scraper 232 are set at an angle to the length direction of the conveyor belt 120, both are in contact with the upper surface 121a of the return section 121, and both are mounted on the support base 220.

[0061] With this design, when the belt conveyor 100 experiences a return stroke with material, since both the first scraper 231 and the second scraper 232 are in contact with the upper surface 121a, the material 10 can be intercepted by the first scraper 231 and the second scraper 232, preventing the material 10 from being rolled into the roller 130 behind the scraper 230. Since the distance between the first scraper 231 and the second scraper 232 gradually increases along the running direction of the conveyor belt 120, and both the first scraper 231 and the second scraper 232 are set at an angle to the length direction of the conveyor belt 120, the material 10 can move towards both sides of the width direction of the conveyor belt 120 under the guidance of the first scraper 231 and the second scraper 232, and fall off from both sides of the conveyor belt 120. This helps to increase the falling speed of the material 10 and reduce the accumulation of the material 10.

[0062] Both the first scraper 231 and the second scraper 232 are set at an angle to the length direction of the conveyor belt 120. That is, the first scraper 231 is not parallel to the length direction of the conveyor belt 120, and the second scraper 232 is also not parallel to the length direction of the conveyor belt 120. The angle setting can be a right angle, an acute angle, or an obtuse angle. The first scraper 231 and the second scraper 232 can be connected together by means of bonding, welding, snap-fitting, etc.

[0063] The materials of the first scraper 231 and the second scraper 232 are varied, such as metal and plastic, and are not limited in this application. In some embodiments, both the first scraper 231 and the second scraper 232 are made of rubber.

[0064] like Figure 2 As shown, in some embodiments, the included angle α between the first scraper 231 and the second scraper 232 is 90° to 120°, such as 90°, 95°, 96°, 110°, 120°, etc.

[0065] like Figure 2 As shown, in some embodiments, the support base 220 includes a first support base 221 and a second support base 222, with one end of the first support base 221 and one end of the second support base 222 connected; the first support base 221 and / or the second support base 222 are mounted on the adjusting assembly 210; along the running direction of the conveyor belt 120, the distance between the first support base 221 and the second support base 222 gradually increases; both the first support base 221 and the second support base 222 are set at an angle to the length direction of the conveyor belt 120; a first scraper 231 is mounted on the first support base 221, and a second scraper 232 is mounted on the second support base 222.

[0066] The first support base 221 and the second support base 222 are fixedly connected, and can be connected by bolts, welding, or other methods. It is permissible for only the first support base 221 to be installed on the adjusting assembly 210, only the second support base 222 to be installed on the adjusting assembly 210, or both the first support base 221 and the second support base 222 to be installed on the adjusting assembly 210. The first scraper 231 and the second scraper 232 are respectively installed on the first support base 221 and the second support base 222, and the first support base 221 and the second support base 222 respectively support the first scraper 231 and the second scraper 232.

[0067] In some embodiments, the first support 221 and the second support 222 are both channel steels, and the first support 221 and the second support 222 are welded and fixed.

[0068] In some embodiments, three adjustment components 210 are provided, and the support base 220 has three clearance through holes 220a. One clearance through hole 220a is located at the end of the first support base 221 away from the second support base 222, one clearance through hole 220a is located at the end of the second support base 222 away from the first support base 221, and one clearance through hole 220a is located at the end where the first support base 221 and the second support base 222 connect, and is formed by the first support base 221 and the second support base 222 together. The three adjustment components 210 are respectively disposed in the three clearance through holes 220a.

[0069] In some embodiments, the pressure plate 240 includes a first pressure plate 241 and a second pressure plate 242. The first pressure plate 241 is disposed on the side of the first scraper 231 away from the first support base 221, and the first pressure plate 241 presses against the first scraper 231. The second pressure plate 242 is disposed on the side of the second scraper 232 away from the second support base 222, and the second pressure plate 242 presses against the second scraper 232. In these embodiments, a plurality of connectors 250 are provided, some of which are connected to the first pressure plate 241 and some of which are connected to the second pressure plate 242.

[0070] In some embodiments, eight connectors 250 are provided, with four connectors 250 each on the first pressure plate 241 and the second pressure plate 242.

[0071] In some embodiments, along the height direction, the first pressure plate 241, the second pressure plate 242, the first support 221, and the second support 222 are all disposed in the middle region of the scraper 230.

[0072] In some embodiments, along the width direction of the conveyor belt 120, the two ends of the first pressure plate 241 and the two ends of the first scraper 231 are flush, and the two ends of the second pressure plate 242 and the two ends of the second scraper 232 are flush.

[0073] In some embodiments, along the width direction of the conveyor belt 120, the end of the first support 221 away from the second support 222 extends out of the conveyor belt 120, and the end of the second support 222 away from the first support 221 also extends out of the conveyor belt 120.

[0074] The working principle of the conveying device 100 is described below:

[0075] When the belt conveyor 100 experiences a return stroke with material, since both the first scraper 231 and the second scraper 232 are in contact with the upper surface 121a, the material 10 can be intercepted by the first scraper 231 and the second scraper 232, preventing the material 10 from being rolled into the roller 130 behind the scraper 230. Since the distance between the first scraper 231 and the second scraper 232 gradually increases along the running direction of the conveyor belt 120, and both the first scraper 231 and the second scraper 232 are set at an angle to the length direction of the conveyor belt 120, the material 10 can move towards both sides of the width direction of the conveyor belt 120 under the guidance of the first scraper 231 and the second scraper 232, and fall off from both sides of the conveyor belt 120.

[0076] When the scraper 230 wears down and no longer contacts the upper surface 121a of the conveying section 122 of the conveyor belt 120, loosen the first nut 212 and the second nut 213, and screw the first nut 212 and the second nut 213 down to a certain height. Then move the support seat 220 down until the scraper 230 contacts the surface 121a again. Then tighten the first nut 212 and the second nut 213 to clamp the support seat 220, and the support seat 220 is fixed at the adjusted height.

[0077] When scraper 230 is severely worn and needs to be replaced, unscrew nut 252 to remove it from bolt 251 and pull out bolt 251. Then remove pressure plate 240 and scraper 230, replace with a new scraper 230, insert bolt 251 into pressure plate 240, new scraper 230 and support base 220, and connect nut 252.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0079] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.
