Description

Technical Field

[0001] The utility model relates to the technical field of machine-made sand production equipment, in particular to a long-distance conveying gallery belt conveyor for sand and gravel aggregates. Background Art

[0002] There is a 12km belt conveyor corridor between our company's production plant and the wharf. The belt conveyor in the conveyor corridor consists of multiple sections. During the conveying process, the upstream belt conveyor transports the sand and gravel aggregates to the downstream belt conveyor, thereby transporting the sand and gravel aggregates to the wharf in sections.

[0003] During the conveying process, the uneven stacking of sand and gravel aggregates will cause the belt to tilt, and the sand and gravel aggregates on the upper belt will fall onto the belt on the upper side of the support roller. The sand and gravel aggregates that fall onto the belt on the upper side of the support roller will move with the belt, and will collide with the passive roller of the belt conveyor, causing the belt to shift or be damaged. In addition, when the sand and gravel aggregates fall from the upstream belt conveyor to the downstream belt conveyor, a lot of dust will be raised, and this dust will also fall onto the belt on the upper side of the support roller. Over time, a lot of dust will adhere to the belt on the upper side of the support roller, that is, the inner side of the belt, which will cause the belt to deviate to one side and the belt to slip during conveying. Therefore, the dust on the inner side of the belt needs to be separated.

[0004] Chinese patent document CN218706575U, publication (announcement) date: 2023.03.24, discloses a triangular belt cleaner, which is characterized in that the scattered material on the return surface of the conveyor belt is removed by a V-shaped scraper; its disadvantage is that when the sand and gravel aggregates fall from the upstream belt conveyor to the downstream belt conveyor, the unloading end of the upstream belt conveyor is also provided with a tensioning roller device and a driving roller device. The dust may have been squeezed by the tensioning roller and the driving roller, and the V-shaped scraper cannot effectively separate the dust from the belt. Utility Model Content

[0034] The roller brush 50 is of prior art, and the bristles on the roller brush 50 are wear-resistant nylon bristles.

[0035] For details, see Figure 4 , 5 The material blocking device 40 includes a guide frame 43, and the two sides of the guide frame 43 are respectively connected to the extension frame 44. The front side of the guide frame 43 is installed with a scraper 46 through a pressure plate 47. The pressure plate 47 is connected to the guide frame 43 by bolts, and the scraper 46 is clamped between the pressure plate 47 and the guide frame 43. The scraper 46 contacts the belt 60. The extension frame 44 is installed with a bearing seat 51. The central shafts of the two ends of the roller brush 50 are respectively installed on the bearing seats 51 on both sides. The central shaft of one end of the roller brush 50 extends out of the extension frame 44 and is installed with a second sprocket 52. The installation of the roller brush 50 is achieved through the above structure. In this embodiment, the scraper 46 is made of a rubber plate.

[0036] See also Figure 2 , 4 A first connecting plate 41 is installed on the guide frame 43, and first hinged columns 42 are installed on the outer sides of the extension frames 44 on both sides, and a second connecting plate 12 is installed on the frame 11 above the position corresponding to the first connecting plate 41, and a second hinged column 13 is installed above the position corresponding to the first hinged column 42.

Through the above structure, the material blocking device 40 can be stably contacted with the belt 60 under the action of gravity.

[0037] In this embodiment, see Figure 4 The guide frame 43 is triangular or V-shaped, and the first connecting plate 41 is located at the front end tip of the guide frame 43 .

[0038] Furthermore, a support rod 45 is installed in the guide frame 43 to improve the structural strength of the material blocking device 40 .

[0039] In this embodiment, the guide frame 43 and the support rod 45 are angle steels.

[0040] Embodiment 2:

[0041] The difference from the first embodiment is that, see Figure 5 The guide frame 43 is a structure inclined to one side, and the first connecting plate 41 is located in the middle of the upper side of the guide frame 43 .

[0042] Furthermore, support rods 45 are installed inside the extension frames 44 on both sides to improve the structural strength of the material blocking device 40.

[0043] Embodiment three:

[0044] Based on the first embodiment, since only one support roller 20 drives the roller brush 50 to rotate, the support roller 20 may slip. Figure 3 A third sprocket 22 is also installed on the support roller 20 adjacent to the support roller 20 on which the first sprocket 21 is installed, and the third sprocket 22 is connected to the first sprocket 21 through a second chain 23. The roller brush 50 is driven to rotate by the linkage of multiple support rollers 20, thereby ensuring the reliability of the rotation of the roller brush 50. In this embodiment, the first sprocket 21 adopts a double-row sprocket.

[0045] The working principle or action process of the utility model is as follows:

[0046] When the belt conveyor is running, the material blocking device 40 will block the sand and gravel aggregate falling on the belt 60 and guide them to both sides of the belt 60.

[0047] The rotation of the belt 60 drives the support roller 20 to rotate, and the rotation of the support roller 20 drives the first sprocket 21 to rotate. Since the first sprocket 21 and the second sprocket 52 are connected and driven by the first chain 53, the roller brush 50 is driven to rotate. Figure 2 When the roller brush 50 rotates, the bristles contact the belt 60 , thereby separating the dust on the belt 60 .

[0048] It should be noted that after the dust is separated, the dust can be sucked out from the belt by means of negative pressure wind. For example, a negative pressure cover is installed on the material blocking device 40, and the negative pressure cover is connected to the negative pressure air duct, and the separated dust is sucked out by the principle of a vacuum cleaner.
