DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0032] Please refer to Figures 1-11 The present application provides a technical solution:

[0033] Embodiment one

[0034] A belt conveyor tail sweeper, comprising a scraper 1; further comprising a cleaning plate 2, the cleaning plate 2 is located on the scraper 1, the cleaning plate 2 and the scraper 1 are slidingly connected; the abutting mechanism 3 is located in the inner wall of the scraper 1, the abutting mechanism 3 can always keep in contact with the surface of the conveyor belt according to different recess degree of the conveyor belt; the emptying mechanism 4 is connected with the cleaning plate 2, the emptying mechanism 4 drives the cleaning plate 2 to move on the surface of the scraper 1, and the emptying mechanism 4 is connected with the abutting mechanism 3;

[0035] In use, the worker places the scraper 1 at the bottom of the belt conveyor tail in the shutdown state, and the abutting mechanism 3 is attached to the lower surface of the belt. When the belt rotates, the abutting mechanism 3 slides relative to the belt to clean the residual floating coal on the surface of the belt. The floating coal cleaned falls above the scraper 1, and the emptying mechanism 4 arranged can automatically control the cleaning plate 2 to move on the surface of the scraper 1 every time the abutting mechanism 3 cleans for a period of time, so as to push the floating coal collected on the surface of the scraper 1 out, facilitating the worker to clean, reducing the cleaning difficulty of the worker, and avoiding the worker from being in danger when cleaning. Since the bulk materials such as coal in the conveying process will impact the conveying belt, especially at the material falling port, the impact force of the materials will cause the conveying belt to inwardly sag, so that the center of the belt will inwardly sag after a period of use. The abutting mechanism 3 can continue to be attached to the surface of the conveying belt, so as to avoid that the floating coal on the surface of the conveying belt is not cleaned completely.

[0036] The abutting mechanism 3 comprises a rubber plate 30 slidably connected to the inner wall of the scraper 1. The rubber plate 30 is made of rubber material and can be deformed. Seven support plates 31 are fixedly connected to the inner wall of the rubber plate 30. The seven support plates 31 are distributed at equal intervals. Seven transmission boxes 32 slidably connected to the support plates 31 are fixedly connected to the inner wall of the scraper 1. Drive members 33 for pushing the support plates 31 to slide along the inner wall of the transmission boxes 32 are arranged on the inner wall of the transmission boxes 32. Connection blocks 34 are fixedly connected to the outer side of the rubber plate 30. The connection blocks 34 are provided with seven connection blocks corresponding to the seven support plates 31. Control members 35 for controlling the working of the drive members 33 are arranged on the inner wall of the connection blocks 34.

[0037] When the abutting mechanism 3 works, the seven support plates 31 serve as a framework to support the shape of the rubber plate 30, so that the rubber plate 30 can be attached to the bottom of the belt. When the belt slides relative to the rubber plate 30, the rubber plate 30 can clean the floating coal on the surface of the belt. If the sagging degree of the surface of the belt increases with the use of the belt, the rubber plate 30 cannot be completely attached to the surface of the belt at this time. The control members 35 monitor whether the floating coal on the surface of the belt is cleaned completely, and control the working of the drive members 33. The drive members 33 drive the support plates 31 located below the belt which is not cleaned completely to slide upward on the inner wall of the transmission boxes 32. The support plates 31 slide upward to make part of the rubber plate 30 around the support plates 31 protrude. The support plates 31 at other positions do not move, so that the shape of the rubber plate 30 at the position of the moving support plates 31 changes to be attached to the changed surface of the belt again, so as to avoid that the floating coal on the surface of the belt is not cleaned completely.

[0038] The driving member 33 comprises a piston plate one 36 fixedly connected with the support plate 31, the piston plate one 36 is in sliding connection with the inner wall of the transmission box 32, the one end of the piston plate one 36 away from the support plate 31 is fixedly connected with the reset spring one 37, the reset spring one 37 is fixedly connected with the inner wall of the transmission box 32, the reset spring one 37 drives the plurality of piston plate one 36 to reset when the new belt is replaced, so that the shape of the rubber plate 30 resets, the bottom of the transmission box 32 is communicated with the connecting pipe one 38, the plurality of connecting pipe one 38 is connected with the connecting box 39, the connecting box 39 is hollow, so that the connecting box 39 can input the gas in the connecting box 39 into the plurality of connecting pipe one 38, the outer side of the connecting box 39 is communicated with the gas pipe 310, the gas pipe 310 is Y-shaped pipe, the input end of the gas pipe 310 is fixedly connected with the air pump 311;

[0039] When the driving member 33 works, the air pump 311 works and inputs the gas into the gas pipe 310, the gas flow is filled into the connecting box 39 through the gas pipe 310, when the control device 35 detects that the belt is not cleaned in some area, the control device 35 controls the connecting pipe one 38 below the area to be in the communication state, so that the gas enters the transmission box 32 through the connecting pipe one 38, the gas pressure at the bottom of the transmission box 32 increases, so as to drive the piston plate one 36 to move upwards along the inner wall of the transmission box 32, the piston plate one 36 drives the support plate 31 to move upwards to cooperate with the rubber plate 30 to protrude in the corresponding area, so as to cooperate with the rubber plate 30 in the area to be able to adhere to the surface of the belt again.

[0040] The control device 35 comprises a transmission shaft 312 rotatably connected with the inner wall of the connecting block 34, the outer side of the transmission shaft 312 is fixedly connected with the transmission wheel 313, the plurality of connecting blocks 34 are located on the outer side of the scraper 1, and the height of the transmission wheel 313 is higher than that of the rubber plate 30, the end of the transmission shaft 312 is fixedly connected with the rotating rod 314, the rotating rod 314 is located in the inner wall of the connecting block 34, the inner wall of the connecting block 34 is provided with a rotation speed sensor 315 for detecting the rotation of the rotating rod 314, the inner wall of the scraper 1 is provided with a controller 316 connected with the rotation speed sensor 315, the outer side of the connecting pipe one 38 is fixedly connected with a direct current electromagnetic valve 317, the controller 316 is connected with the direct current electromagnetic valve 317 located below;

[0041] The direct current electromagnetic valve 317 is a kind of electromagnetic valve controlled by direct current in prior art, which is composed of an electromagnet and a valve body, when the electromagnet is powered, the magnetic field generated by the electromagnet will attract the valve body, thereby changing the flow passage inside the valve, so that the liquid can flow through or be cut off, the direct current electromagnetic valve 317 has the characteristics of fast response, low energy consumption, simple structure, small size, light weight, convenient installation and use, etc., and is widely used in automatic control system, and the method for controlling opening and closing of the direct current electromagnetic valve 317 is mainly realized by controlling the on-off of voltage, specifically, when the direct current electromagnetic valve 317 is powered, the electromagnet will generate a certain magnetic field force, which will push the valve core of the valve to move, thereby controlling the opening of the valve, when the power is off, the magnetic field force disappears, and the valve core returns to the original position under the action of the spring, and the valve is closed.

[0042] Since the connecting block 34 is located outside the scraper 1, the belt will first pass through the rubber plate 30 and then pass through the transmission wheel 313 when rotating, and the transmission wheel 313 is located at the bottom of the belt, since the height of the transmission wheel 313 is slightly higher than that of the rubber plate 30, if the floating coal on the surface of the belt is cleaned, the transmission wheel 313 can be stably rotated through the friction between the belt and the transmission wheel 313, if the floating coal is still on the surface of the belt, it indicates that part of the rubber plate 30 is not in contact with the surface of the belt, the mutual extrusion force between the belt and the transmission wheel 313 is reduced, and there is still floating coal on the surface of the belt, so that the transmission wheel 313 and the belt are prone to relative sliding, the rotation speed of the rotating rod 314 is monitored in real time by the rotation speed sensor 315, and when the rotation speed of the rotating rod 314 changes, the change information is output to the controller 316, the controller 316 controls the direct current electromagnetic valve 317 located below the controller 316 to open, so that the gas in the connecting box 39 can enter the bottom of the transmission box 32 through the connecting pipe one 38, and push the supporting plate 31 to move upward, the opening time of the direct current electromagnetic valve 317 controlled by the controller 316 is fixed as 2 seconds each time, and the direct current electromagnetic valve 317 is closed again after 2 seconds, so that the height of the supporting plate 31 is adjusted only slightly each time, until the rotation speed of the rotating rod 314 is stable, which indicates that the friction between the belt and the transmission wheel 313 is stable, that is, the floating coal on the surface of the belt is cleaned, and the shape adjustment of the rubber plate 30 is completed, so that the rubber pad can be in contact with the surface of the belt again.

[0043] The emptying mechanism 4 comprises a connecting rod 40 fixedly connected with the cleaning plate 2, the connecting rod 40 being in sliding connection with the inner wall of the scraper 1, a transmission block 41 being fixedly connected below the connecting rod 40, a transmission rod 42 being fixedly connected with the transmission block 41, a supporting cylinder 43 being located outside the transmission rod 42, an air inlet groove 415 being formed in the inner wall of the supporting cylinder 43, the air inlet groove 415 being in communication with a connecting pipe two 46, the supporting cylinder 43 being fixedly connected with the bottom of the scraper 1, a piston plate two 44 being fixedly connected at the end of the transmission rod 42 away from the transmission block 41, the piston plate two 44 being in sliding connection with the inner wall of the supporting cylinder 43, a reset spring two 45 being fixedly connected outside the transmission block 41, the reset spring two 45 being fixedly connected with the inner wall of the scraper 1, the connecting pipe two 46 being in communication between the supporting cylinder 43 and the connecting box 39, a three-way electromagnetic valve one 47 being fixedly connected outside the connecting pipe two 46, a control switch one 48 being installed on the inner wall of the supporting cylinder 43, the control switch one 48 being capable of controlling the three-way electromagnetic valve one 47 and a three-way electromagnetic valve two 413, the output end of the gas conveying pipe 310 being provided with a control member 49 for controlling the opening and closing of the three-way electromagnetic valve one 47;

[0044] When the emptying mechanism 4 works, the three-way electromagnetic valve one 47 is controlled to be opened by the control member 49, at this time, the air inlet groove 415 and the connecting box 39 are communicated through the connecting rod 40, so that the gas in the connecting box 39 enters the inside of the supporting cylinder 43 through the connecting pipe two 46, the air pressure drives the piston plate two 44 to slide outward along the inner wall of the supporting cylinder 43, the piston plate two 44 drives the transmission rod 42 to move, the transmission rod 42 drives the transmission block 41 to move, the transmission block 41 stretches the reset spring two 45, and the transmission block 41 drives the connecting rod 40 to move to cooperate with pulling the cleaning plate 2 to slide on the inner wall of the scraper 1 to cooperate with cleaning the cinder on the inner wall of the scraper 1, when the piston plate moves along the inner wall of the supporting cylinder 43 to contact the control switch one 48, the control switch one 48 controls the three-way electromagnetic valve one 47 to switch to a state of being in communication with the outside, the reset spring two 45 in the stretched state drives the transmission block 41 to reset, the transmission block 41 drives the connecting rod 40 to reset, and the connecting rod 40 drives the cleaning plate 2 to sweep on the surface of the scraper 1 again to cooperate with cleaning the cinder out of the inside of the belt conveyor tail again.

[0045] The control member 49 comprises a gas storage box 410 fixedly connected with the output end of the gas conveying pipe 310, a piston plate three 411 being in sliding connection with the inner wall of the gas storage box 410, a compression spring 412 being fixedly connected outside the piston plate three 411, the compression spring 412 being fixedly connected with the inner wall of the gas storage box 410, a three-way electromagnetic valve two 413 being fixedly connected at the end of the gas conveying pipe 310 close to the gas storage box 410, a control switch two 414 being fixedly connected with the inner wall of the gas storage box 410, the control switch two 414 being connected with the three-way electromagnetic valve one 47 and the three-way electromagnetic valve two 413;

[0046] In the conventional state, the three-way electromagnetic valve 413 is in communication with the gas storage box 410, and the gas pump 311 injects gas into the inner wall of the gas storage box 410. As the gas flows into the gas storage box 410, the gas pressure pushes the piston plate 411 to slide along the inner wall of the gas storage box 410 and compresses the compression spring 412. When the piston plate 411 triggers the control switch 414, the control switch 414 controls the three-way electromagnetic valve to switch to a state of communication between the second connecting pipe 46 and the gas inlet groove 415, thereby being able to control the cleaning plate 2 to clean the surface of the scraper 1 at regular intervals. At the same time, the control switch 414 controls the three-way electromagnetic valve 413 to switch to a state of communication between the gas storage box 410 and the outside. The compression spring 412 in the compressed state pushes the piston plate 411 to reset. When the piston plate 44 triggers the control switch 48, the three-way electromagnetic valve 47 controls the support cylinder 43 to be in communication with the outside, and the three-way electromagnetic valve 413 controls the gas storage box 410 to be in communication with the gas pipe 310, so as to drive the cleaning plate 2 to move next time.

[0047] When the gas pump 311 increases the gas flow to drive the support plate 31 to move upward, the gas flow rate in the gas pipe 310 increases, and thus the gas flow entering the gas storage box 410 also increases, so that the interval time of the cleaning plate 2 moving on the surface of the scraper 1 is shortened. After the belt is recessed to a certain extent, the surface of the belt is more likely to have residual floating coal, so that the amount of floating coal falling on the surface of the scraper 1 increases, and the moving frequency of the cleaning plate 2 is increased to avoid too much floating coal accumulated on the surface of the scraper 1.
