[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 7 As shown, the present invention provides a belt conveyor tail cleaner, comprising a workbench 1, including: a support wall 3 is symmetrically installed on the top of the workbench 1, and the workbench 1 includes a feeding mechanism 4 for feeding, a secondary cleaning mechanism 7 for secondary cleaning, a tertiary cleaning mechanism 8 for tertiary cleaning, and a tension cleaning mechanism 9 for adaptive tension cleaning;

[0035] A mounting plate 91 is symmetrically installed on the top of the workbench 1, and a telescopic column 92 is slidably connected inside the mounting plate 91. The mounting plate 91 is fixedly connected to the top of the workbench 1, and the bottom end of the telescopic column 92 passes through the workbench 1 and extends to the outside. The bottom end of the telescopic column 92 is fixedly connected to the same mounting block 94, and the outer wall of the telescopic column 92 is sleeved with a first spring 93, and the top end of the first spring 93 is fixedly connected to the bottom end of the mounting block 94, and the bottom end of the first spring 93 is fixedly connected to the top of the mounting plate 91. A roller 95 is fixedly installed on one side of the top end of the mounting block 94, and the top end of the roller 95 contacts the bottom end surface of the conveyor belt 45.

[0036] In the present embodiment, when the conveyor belt 45 becomes loose during operation, the pressure of the conveyor belt 45 on the roller 95 is reduced, and then under the elastic action of the first spring 93, the first spring 93 is extended, and the first spring 93 pushes the mounting block 94 to move upward, thereby driving the telescopic column 92 to slide upward in the mounting plate 91, so that the roller 95 can always be in close contact with the bottom surface of the conveyor belt 45, thereby adjusting the tension of the conveyor belt 45, preventing the conveyor belt 45 from slipping, running off track, and other situations that affect normal operation due to being too loose, thereby ensuring the stability of the conveyor belt 45 during operation and reducing equipment failures.

[0037] In a further embodiment, a slide groove 96 and a rebound groove 97 are opened inside the mounting block 94, and a slide rod 99 is slidably connected to the inner wall of the slide groove 96, and a scraper 910 is fixedly connected to the outer surface of the slide rod 99, and the top end of the scraper 910 contacts the bottom end surface of the conveyor belt 45.

[0038] In this embodiment, when the conveyor belt 45 is running, on the one hand, the roller 95 rolls at the bottom end of the conveyor belt 45 to play a tensioning and adjusting role to prevent the conveyor belt 45 from being excessively loose or shaking. On the other hand, since the scraper 910 is in close contact with the conveyor belt 45, as the conveyor belt 45 continues to move, the scraper 910 will scrape off the material remaining on the surface of the conveyor belt 45 and make it separate from the surface of the conveyor belt 45, thereby achieving a relatively comprehensive preliminary cleaning of the bottom surface of the conveyor belt 45 and greatly reducing the amount of material remaining on the conveyor belt 45.

[0039] In a further embodiment, the inclined surface of the rebound groove 97 is movably connected to a second spring 98 , and one end of the second spring 98 is in contact with one side of the scraper 910 .

[0040] In this embodiment, the scraper 910 can be reset in time through the elastic force of the second spring 98, ensuring that the scraper 910 can always contact the bottom surface of the conveyor belt 45 for cleaning during the operation of the conveyor belt 45, and will not be interrupted or reduced in cleaning effect due to greater resistance, thereby always maintaining a good initial cleaning effect. The setting of the second spring 98 and the rebound groove 97 effectively protects the scraper 910 from damage caused by sudden large impact force, thereby extending the service life of the scraper 910.

[0041] In a further embodiment, a dual-axis motor 6 is fixedly installed on one side of the top of the workbench 1, and a first sprocket 71 is fixedly sleeved on the output shaft at one end of the dual-axis motor 6. A chain 72 is meshingly installed on the outer surface of the first sprocket 71, and a second sprocket 73 is meshingly installed at one end of the chain 72. A brush 74 is fixedly sleeved inside the second sprocket 73, and one end of the brush 74 passes through the support wall 3 and extends to the inside of the support wall 3 on the other side. The surface of the support wall 3 is in contact with the bottom end surface of the conveyor belt 45.

[0042] In this embodiment, when the conveyor belt 45 is running, the dual-axis motor 6 is started, and the output shaft at one end thereof drives the first sprocket 71 to rotate, and the first sprocket 71 drives the second sprocket 73 to rotate through the chain 72. When the second sprocket 73 rotates, the brush 74 will rotate synchronously therewith. During the rotation of the brush 74, its bristles will continuously brush the bottom surface of the conveyor belt 45, and clean up the relatively fine material particles remaining on the surface of the conveyor belt 45, thereby further enhancing the comprehensiveness of the cleaning and ensuring the cleaning quality of the bottom surface of the entire conveyor belt 45.

[0043] In a further embodiment, the output shaft at the other end of the dual-axis motor 6 passes through the side wall of the air collecting box 81 and is fixedly sleeved with an impeller 82. The impeller 82 is rotatably connected to the inner wall of the air collecting box 81. An air outlet pipe 83 is opened at the top of the air collecting box 81. A diverter pipe 84 is fixedly sleeved at the top of the air outlet pipe 83. One end of the diverter pipe 84 passes through the supporting wall 3 and extends to the inside of the supporting wall 3 on the other side. A plurality of nozzles 85 are fixedly sleeved on the outer surface of the diverter pipe 84.

[0044] In this embodiment, after the dual-axis motor 6 is started, the output shaft at the other end drives the impeller 82 to rotate in the inner wall of the air collecting box 81. The rotation of the impeller 82 causes the outside air to be drawn in and accelerate the flow, and then flows from the air outlet pipe 83 to the diversion pipe 84. When the airflow reaches the diversion pipe 84, it will be sprayed through a number of nozzles 85 to the junction of the brush 74 and the bottom surface of the conveyor belt 45, thereby further blowing away the particles that are difficult to be completely removed by the brush 74 due to electrostatic adsorption or viscosity, making the cleaning more in-depth and thorough, thereby significantly improving the cleaning quality, reducing material residue, and further optimizing the cleaning effect.

[0045] In a further embodiment, a feeding motor 41 is fixedly installed on the left end of the top of the workbench 1, and a small pulley 42 is fixedly sleeved on the output shaft of the feeding motor 41. A belt 43 is meshedly installed on the outer surface of the small pulley 42, and a large pulley 44 is meshedly installed on one end of the belt 43, and a conveyor belt 45 drive roller is fixedly sleeved inside the large pulley 44.

[0046] In this embodiment, the feeding motor 41 is first started, and its output shaft drives the small pulley 42 to rotate. The small pulley 42 drives the large pulley 44 to rotate through the belt 43. When the large pulley 44 rotates, it will drive the transmission roller of the conveyor belt 45 to rotate, so that the entire conveyor belt 45 can operate, so that the material can be smoothly transported from one end to the other, realizing the material transportation function and meeting the material transportation needs in the production process.

[0047] In a further embodiment, a disassembly groove 31 is opened inside the support wall 3, and a slide rod 99 is slidably connected to the inner wall of the disassembly groove 31, and one end of the slide rod 99 passes through the inner wall of the disassembly groove 31 and extends to the outside.

[0048] In this embodiment, when the scraper 910 needs to be repaired or replaced, the operator only needs to slide the slide bar 99 along the inner wall of the disassembly groove 31 to disengage it from the connection state outside the support wall 3, and then the components connected to the slide bar 99 can be easily removed without complicated disassembly operations, which greatly shortens the maintenance time and improves the efficiency of equipment maintenance. The slide bar 99 can also slide up and down on the inner wall of the disassembly groove 31, so as not to affect the roller 95 and hinder the tensioning adjustment of the conveyor belt 45.

[0049] In a further embodiment, a discharge plate 5 is provided on the inner side of the support wall 3 , and the discharge plate 5 is fixedly connected to the top right end of the workbench 1 .

[0050] In this embodiment, the unloading plate 5 can prevent excessive accumulation of materials at the tail of the conveyor belt 45, ensure that the materials are accurately unloaded from the conveyor belt 45 to the designated location, maintain the normal operation of the conveyor belt 45, and ensure the smooth progress of the production process.

[0051] In a further embodiment, a plurality of legs 2 are installed at the bottom end of the workbench 1, and the plurality of legs 2 have the same size.

[0052] In this embodiment, the legs 2 can provide stable support for the workbench 1. Legs 2 of the same size can evenly share the weight of the device, ensuring that the workbench 1 remains stable in the working state and will not tilt or shake due to uneven force, thereby providing reliable basic support for the normal operation of the device.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
