Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a conveyor belt cleaning mechanism and conveying device. Background Technology

[0002] When belt conveyors transport bulk materials, due to the characteristics of the materials themselves and their moisture content, most of the material adheres to the conveyor belt after being discharged from the discharge roller, becoming sticky material. To prevent this sticky material from affecting the operation of the conveyor belt, it needs to be cleaned with scrapers. Conventional scrapers have fixed scrapers, with the conveyor belt hanging down under gravity and sticking tightly to the scraper. This is suitable for situations with less sticky material and lower adhesion. However, when there is more sticky material and it is more adhesive, springs need to be installed to apply pressure to ensure the scraper is pressed tightly against the conveyor belt. Although this provides some pressure, it makes the scraper structure complex and increases costs. Moreover, existing scrapers are installed below the discharge roller, competing for space with other components of the belt conveyor, making installation and maintenance difficult. In addition, existing scrapers are of a single-piece structure. Since bulk materials often concentrate in the middle of the conveyor belt during transport, the scraper often needs to be replaced entirely due to severe wear in the middle section, further increasing costs. Utility Model Content

[0003] In view of this, the present invention provides a conveyor belt cleaning mechanism that utilizes the lever principle to ensure that the scraper generates a sufficiently large clamping force to contact the conveyor belt when the pressure structure provides tension, thereby ensuring a better cleaning effect.

[0004] A conveyor belt cleaning mechanism includes two curved arms, a connecting rod, at least one scraper, and a pressure applying structure. The connecting rod is connected between the two curved arms, and the scraper is connected to the connecting rod. The two curved arms include a first connecting end and a second connecting end disposed opposite to each other. The first connecting ends of the two curved arms are configured to be rotatably connected to both sides of the conveyor mechanism. The second connecting ends of the two curved arms are connected to the pressure applying structure, which is configured to provide tension to the two curved arms so that the scraper contacts the conveyor belt of the conveyor mechanism.

[0005] Optionally, each of the crank arms includes a first section and a second section connected at an angle, and a mounting hole is provided at the connection between the first section and the second section. The two ends of the connecting rod pass through the mounting holes of the two crank arms.

[0006] Optionally, the first connecting end is provided with a hinge hole and a hinge shaft that mates with the hinge hole, the hinge shaft being used to connect the conveying mechanism.

[0007] Optionally, the conveyor belt cleaning mechanism includes a plurality of scrapers, which are arranged side by side and connected to the connecting rod.

[0008] Optionally, each of the scrapers is provided with a through hole, and the connecting rod is provided through the through hole of each of the scrapers. The position of each scraper on the connecting rod can be interchanged by disassembling the crank arm and the connecting rod.

[0009] Optionally, the conveyor belt cleaning mechanism includes a first limiting member and a second limiting member, the first limiting member and the second limiting member being detachably connected to the connecting rod, and a plurality of scrapers being limited between the first limiting member and the second limiting member.

[0010] Optionally, the conveyor belt cleaning mechanism includes a third limiting member and a fourth limiting member. The third limiting member is detachably connected to one end of the connecting rod, and the fourth limiting member is detachably connected to the other end of the connecting rod. The third limiting member and the fourth limiting member cooperate with the two crank arms to limit the connecting rod.

[0011] Optionally, the scraper includes a first edge and a second edge arranged symmetrically on the top and bottom. The scraper has a first state and a second state. When the scraper is connected to the connecting rod in the first state, the first edge is used to contact the conveyor belt. When the scraper is connected to the connecting rod in the second state, the second edge is used to contact the conveyor belt.

[0012] Optionally, the pressure-applying structure includes two elastic bands, each elastic band having a plurality of connecting holes, the plurality of connecting holes being arranged sequentially at intervals along the length direction of the elastic band, and the second connecting end of each of the curved arms being selectively connected to each of the connecting holes.

[0013] Optionally, the pressure-applying structure includes two traction ropes and a counterweight box. One end of each of the two traction ropes is connected to the second connecting end of the two crank arms, and the other end of each traction rope is connected to the counterweight box. Each traction rope is used to be mounted on at least two guide posts on the transmission mechanism so that the counterweight box provides tension to the two crank arms by its own weight.

[0014] This application also relates to a conveying device, including the aforementioned conveyor belt cleaning mechanism.

[0015] The two curved arms of the conveyor belt cleaning mechanism of this utility model utilize the lever principle. When the pressure structure provides tension, it can ensure that the scraper generates a sufficiently large clamping force to contact the conveyor belt. While ensuring a good cleaning effect, it does not increase the structural complexity of the cleaning mechanism, which is beneficial for installation and maintenance. Attached Figure Description

[0025] First Embodiment Figure 1This is a schematic diagram of the conveyor belt cleaning mechanism according to the first embodiment of this application. Figure 2 yes Figure 1 The diagram shown is a side view of the conveyor belt cleaning mechanism connected to the conveyor mechanism. Figure 1 and Figure 2 As shown, the conveyor belt cleaning mechanism includes two curved arms 11, a connecting rod 12, at least one scraper 13, and a pressure applying structure 14. The connecting rod 12 is connected between the two curved arms 11, and the scraper 13 is connected to the connecting rod 12. The two curved arms 11 include a first connecting end 111 and a second connecting end 112 disposed opposite to each other. The first connecting ends 111 of the two curved arms 11 are configured to be rotatably connected to both sides of the conveyor mechanism 20. The second connecting ends 112 of the two curved arms 11 are connected to the pressure applying structure 14, which is configured to provide tension to the two curved arms 11 so that the scraper 13 contacts the conveyor belt 21 of the conveyor mechanism 20. In this embodiment, the direction of the tension provided by the pressure applying structure 14 is perpendicular to the length direction of the curved arms 11.

[0026] The two curved arms 11 of the conveyor belt cleaning mechanism of this application utilize the lever principle to ensure that the scraper 13 generates a sufficiently large clamping force to contact the conveyor belt 21 when the pressure structure 14 provides tension. This ensures a good cleaning effect without increasing the structural complexity of the cleaning mechanism, which is beneficial for installation and maintenance.

[0027] Optionally, such as Figure 1 As shown, each crank arm 11 includes a first segment 11a and a second segment 11b connected at an angle. A mounting hole 101 is provided at the connection between the first segment 11a and the second segment 11b. Both ends of the connecting rod 12 pass through the mounting holes 101 of the two crank arms 11. In this embodiment, the length of the first segment 11a is equal to the length of the second segment 11b; the included angle between the first segment 11a and the second segment 11b is greater than 90° and less than 180°, for example, 120°, 130°, 135°, 140°, 145°, or 150°.

[0028] Optionally, Figure 3 This is a schematic diagram of the connection structure of the first connection end of this application for connecting to the transmission mechanism, as shown below. Figure 1 and Figure 3 As shown, the first connecting end 111 is provided with a hinge hole and a hinge shaft 113 that mates with the hinge hole. The hinge shaft 113 is used to connect the conveyor mechanism 20. When the pressure structure 14 provides tension to the crank arm 11, the crank arm 11 can rotate around the hinge shaft 113 so that the scraper 13 is pressed against the conveyor belt 21.

[0029] Optionally, such as Figure 3As shown, the hinge shaft 113 is, for example, a bolt, to which two nuts 114 and two first washers 115 are connected. The two nuts 114 and the two first washers 115 are fixed to the transmission mechanism 20.

[0030] Optionally, two second washers 116 are provided between the head of the bolt and a nut 114, and the first connecting end 111 is movably disposed between the two second washers 116.

[0031] Optionally, Figure 4 This is a front view schematic diagram of the connection between the connecting rod and multiple scrapers in this application, as shown below. Figure 1 and Figure 4 As shown, the conveyor belt cleaning mechanism includes multiple scrapers 13, which are arranged side by side and connected to the connecting rod 12.

[0032] Optionally, such as Figure 1 and Figure 4 As shown, each scraper 13 has a through hole, and the connecting rod 12 passes through the through hole of each scraper 13. The position of each scraper 13 on the connecting rod 12 can be interchanged by disassembling the crank arm 11 and the connecting rod 12. In this embodiment, the cross-section of the connecting rod 12 is rectangular, and the through hole is a rectangular hole. This design can prevent the scraper 13 from flipping relative to the connecting rod 12.

[0033] The positions of the multiple scrapers 13 on the connecting rod 12 in this application are interchangeable. For example, the scrapers 13 with slight wear on both sides can be swapped to the middle to replace the severely worn scrapers 13 for continued use, thus improving the utilization rate of the scrapers 13. When one or more scrapers 13 are severely worn, the damaged scraper 13 can be removed from the connecting rod 12 and replaced with a new scraper 13 for continued use.

[0034] Optionally, such as Figure 1 and Figure 4 As shown, the conveyor belt cleaning mechanism includes a first limiting member and a second limiting member. The first and second limiting members are detachably connected to the connecting rod 12. A plurality of scrapers 13 are limited between the first and second limiting members to prevent the scrapers 13 from moving freely on the connecting rod 12. In this embodiment, the connecting rod 12 is provided with a first insertion hole 103 and a second insertion hole 104. The first insertion hole 103 is adjacent to the leftmost scraper 13, and the first limiting member is at least partially installed in the first insertion hole 103. The second insertion hole 104 is adjacent to the rightmost scraper 13, and the second limiting member is at least partially installed in the second insertion hole 104.

[0035] Optionally, the first and second limiting members may be, for example, a combination of bolt and nut, or a combination of pin and cotter pin, but are not limited thereto.

[0036] Optionally, such as Figure 1 and Figure 4 As shown, the conveyor belt cleaning mechanism includes a third limiting member and a fourth limiting member. The third limiting member is detachably connected to one end of the connecting rod 12, and the fourth limiting member is detachably connected to the other end of the connecting rod 12. The third and fourth limiting members cooperate with the two crank arms 11 to limit the connecting rod 12 and prevent it from detaching from the crank arms 11. In this embodiment, the connecting rod 12 is provided with a third insertion hole 105 and a fourth insertion hole 106. The third insertion hole 105 is adjacent to the left crank arm 11, and the third limiting member is at least partially installed in the third insertion hole 105. The fourth insertion hole 106 is adjacent to the right crank arm 11, and the fourth limiting member is at least partially installed in the fourth insertion hole 106.

[0037] Optionally, the third and fourth limiting members may be, for example, a combination of bolt and nut, or a combination of pin and cotter pin, but are not limited thereto.

[0038] Optionally, such as Figure 1 and Figure 4 As shown, the scraper 13 includes a first edge 131 and a second edge 132 symmetrically arranged vertically. The scraper 13 has a first state and a second state. When the scraper 13 is connected to the connecting rod 12 in the first state, the first edge 131 is used to contact the conveyor belt 21. When the scraper 13 is connected to the connecting rod 12 in the second state, the second edge 132 is used to contact the conveyor belt 21. When the first edge 131 of the scraper 13 wears down and flips 180°, the second edge 132 of the scraper 13 can continue to contact the conveyor belt 21 without replacing the scraper 13, thus improving the utilization rate of the scraper 13 and reducing costs.

[0039] Optionally, such as Figure 1 and Figure 2 As shown, the pressure-applying structure 14 includes two elastic bands 141, each elastic band 141 having multiple connecting holes 108. The multiple connecting holes 108 are arranged sequentially at intervals along the length of the elastic band 141. The second connecting end 112 of each curved arm 11 can be selectively connected to each connecting hole 108. In this embodiment, the end of each elastic band 141 is connected to the conveying mechanism 20. The elastic force generated by each elastic band 141 pulls each curved arm 11, so that the edge of the scraper 13 abuts against the conveyor belt 21.

[0040] Optionally, the second connecting end 112 is connected to different connecting holes 108, and the elastic band 141 provides different tensions to the crank arm 11. From the bottom end of the elastic band 141 towards the top end, the second connecting end 112 is connected to different connecting holes 108, so that the tension provided by the elastic band 141 to the crank arm 11 gradually increases.

[0041] Optionally, such as Figure 2As shown, the conveyor belt cleaning mechanism is connected below the conveyor mechanism 20. Two curved arms 11 are rotatably connected to the support of the conveyor mechanism 20. The top ends of two elastic bands 141 are connected to the support of the conveyor mechanism 20, and the two elastic bands 141 are connected to the second connecting ends 112 of the two curved arms 11 through connecting holes 108. In this embodiment, the conveyor belt cleaning mechanism can be installed at any position in the middle of the lower idler roller of the conveyor mechanism 20, and is not limited to being installed below the unloading roller, thus simplifying installation and maintenance.

[0042] Second Embodiment Figure 5 This is a side view of the conveyor belt cleaning mechanism connected to the conveyor mechanism according to the second embodiment of this application, as shown in the diagram. Figure 5 As shown, the conveyor belt cleaning mechanism of this embodiment has a similar structure and function to the conveyor belt cleaning mechanism of the first embodiment, except that the pressure structure 14 is different.

[0043] Optionally, such as Figure 5 As shown, the pressure-applying structure 14 includes two traction ropes 142 and a counterweight box 143. One end of each traction rope 142 is connected to the second connecting end 112 of each of the two crank arms 11, and the other end of each traction rope 142 is connected to the counterweight box 143. Each traction rope 142 is mounted on at least two guide posts 22 on the transmission mechanism 20, so that the counterweight box 143 provides tension to the two crank arms 11 by its own weight. The pressure-applying structure 14 of this embodiment can adjust the clamping force by adding or removing counterweights on the ground, and the upper limit of the clamping force provided by the counterweights is greater.

[0044] Optionally, such as Figure 5 As shown, at least two guide posts 22 are provided on both sides of the support of the conveying mechanism 20. Each guide post 22 on both sides of the conveying mechanism 20 is used to support the traction rope 142.
