The material is continuously sent to the conveyor belt and moves with the conveyor belt, thereby realizing the transportation of the material.

[0003] In the use of the conveyor belt in the water-stable mixing plant, it is mainly used to transport the mixed adhesive material of cement and fine aggregate. Due to the adhesion of cement cementitious materials, if these adhesive materials are not cleaned in time, they will get stuck between the conveyor belt and the drive roller. After a long time, the drive roller will be completely stuck, causing the drive roller to stop rotating, and the conveyor belt will also stop, thus losing the transmission function. At present, the adhesive materials stuck in the conveyor belt and the drive roller are generally removed by manual cleaning, which not only requires shutdown, but also requires the use of a hand hammer and a steel chisel to pick them out if the adhesive materials have a certain strength after initial setting, which not only wastes working time, but also affects the normal operation and service life of the belt.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figures 1 to 4 As shown, the embodiment of the present invention provides a device for removing sticky materials from the discharging belt of a water-stabilized mixing station, which is installed on a belt conveyor 1 and includes:

[0028] A carrier frame 2 is provided on the belt conveyor 1;

[0029] A cleaning unit, the cleaning unit comprises a scraper 3, a cleaning brush 4 and a mounting frame 401 for mounting the cleaning brush 4, the scraper 3 and the mounting frame 401 are both provided with a sliding frame 11, and the two sliding frames 11 are both slidably arranged on the supporting frame 2;

[0030] The adjusting unit is rotatably disposed on the carrier frame 2 and connected between the two sliding frames 11 , and is used to control the two sliding frames 11 to move up and down so that the scraper 3 or the cleaning brush 4 abuts against the conveyor belt of the belt conveyor 1 .

[0031] In the embodiment of the present invention, the carrier frame 2 is installed to the head of the belt conveyor 1, and the head of the belt conveyor 1 corresponds to the discharge hopper. The sticky material is transported by the belt conveyor 1 and enters the discharge hopper through its head position. Since the belt conveyor 1 is in an overhead installation state, when the carrier frame 2 is installed, the center line of the carrier frame 2 is at the edge of the discharge hopper. In the initial state, the level of the scraper 3 is higher than and basically flush with the height of the cleaning brush 4, so that the scraper 3 and the cleaning brush 4 can abut against the conveyor belt of the belt conveyor 1. When the belt conveyor 1 is turned on, the belt conveyor The conveyor belt of the machine 1 moves by itself and rubs against the scraper 3 and the cleaning brush 4 by itself. The scraper 3 and the cleaning brush 4 are installed in the order of the scraper 3 first and the cleaning brush 4 later, so that the scraper 3 is close to the head of the conveyor belt. When most of the sticky materials on the conveyor belt enter the discharge hopper through its head position, part of the sticky materials will move with the conveyor belt to the scraper 3 position, and the scraper 3 will intercept and scrape the sticky materials attached to the conveyor belt. After separation from the conveyor belt, the sticky materials will fall into the discharge hopper for recovery under the action of gravity. The whole process does not require shutdown, ensuring normal working efficiency.

[0032] The conveyor belt after being scraped by the scraper 3 has a certain degree of cleanliness, and then under the action of the cleaning brush 4, the conveyor belt can be further cleaned, and the sticky material can be completely cleaned off the conveyor belt, wherein the cleaning brush 4 adopts a hard brush structure.

[0033] Secondly, with the cooperation of the adjustment unit, since the work of the belt conveyor 1 is continuous, when the conveyor belt is thoroughly cleaned by the scraper 3 and the cleaning brush 4, the conveyor belt will still be attached with new sticky materials after half a circle of movement, so the positions of the scraper 3 and the cleaning brush 4 can be adjusted by the adjustment unit. When the sticky materials are continuously transported by the belt conveyor 1, the positions of the two sliding frames 11 can be adjusted by the adjustment unit, so that the sliding frame 11 connected to the scraper 3 moves upward, and the sliding frame 11 connected to the mounting frame 401 moves downward, so that the scraper 3 is in contact with the conveyor belt, and the cleaning brush 4 is separated from the conveyor belt. In the process of conveying sticky materials by the belt conveyor 1, only the scraper is used. 3 can be used to clean the conveyor belt, that is, most of the sticky materials attached to the conveyor belt can be quickly separated from the conveyor belt to avoid condensation, and the cleaning brush 4 can be prevented from being damaged by long-term friction. When the sticky materials are transported, the sliding frame 11 connected to the scraper 3 can be moved downward by the adjustment unit, and the sliding frame 11 connected to the mounting frame 401 can be moved upward, so that the belt conveyor 1 that does not transport sticky materials continues to operate, the cleaning brush 4 is allowed to abut against the conveyor belt and the scraper 3 is separated from the conveyor belt, and the conveyor belt is finally cleaned by the cleaning brush 4 to ensure the best cleaning effect, wherein the cleaning brush 4 can be driven by an external motor so that the cleaning brush 4 can rotate when it abuts against the conveyor belt.

[0034] Based on the above scheme, if Figure 5 As shown, the adjustment unit includes two adjustment plates 5, the two adjustment plates 5 are provided with mounting shafts 503, the two mounting shafts 503 are respectively rotatably arranged on both sides of the carrier 2, both ends of the adjustment plate 5 are provided with movable grooves 501, the two sliding frames 11 are provided with fixed frames 502, and the two fixed frames 502 are respectively slidably arranged in the two movable grooves 501 of the adjustment plate 5; the adjustment plate 5 is rotatably arranged on the carrier 2 through the mounting shafts 503, so that the adjustment plate 5 can rotate with the mounting shafts 503 as the axis, and the fixed frames 502 can slide inside the movable grooves 501 on the adjustment plate 5, and specifically, when adjusting through the adjustment unit, the mounting shafts 503 are rotated, so that the adjustment The section plate 5 rotates. Since the two movable grooves 501 are respectively located at the two ends of the adjustment plate 5, one movable groove 501 moves upward and the other movable groove 501 moves downward. The fixed frame 502 is arranged on the sliding frame 11, so it is limited and can only move upward or downward. Therefore, when the movable groove 501 on the left side of the adjustment plate 5 moves upward, the movable groove 501 lifts the connected fixed frame 502, so that the fixed frame 502 moves in the movable groove 501 and moves upward with the movable groove 501. On the contrary, the fixed frame 502 moves in the movable groove 501 and moves downward with the movable groove 501, thereby completing the up and down adjustment of the scraper 3 and the cleaning brush 4. The adjustment method is mainly completed by the rotation of the mounting shaft 503, so a motor can be connected to the mounting shaft 503 to control the rotation of the mounting shaft 503 to complete the adjustment.

[0035] Specifically, in order to reduce equipment costs and save energy, such as Figure 3 As shown, telescopic parts 7 are provided on both sides of the carrier 2, and mounting seats 701 are provided at both ends of one of the sliding frames 11, and the two telescopic parts 7 are respectively connected to the two mounting seats 701; the transmission of the mounting shaft 503 is released, a mounting seat 701 is fixedly set on one of the sliding frames 11, and a telescopic part 7 is set on the side of the carrier 2, and the telescopic part 7 adopts a hydraulic rod to connect the telescopic end of the telescopic part 7 to the mounting seat 701, and the mounting seat 701 is controlled to descend or rise by the telescopic end of the telescopic part 7, so as to synchronously adjust the connected sliding frames 11, and the telescopic parts 7 located on both sides of the carrier 2 are controlled by the same hydraulic station to synchronously lift and lower the same sliding frame 11, and when the telescopic part 7 controls the connected sliding frame 11 to move downward, the corresponding end of the adjustment plate 5 moves downward, so that the other end thereof rises, and when the telescopic part 7 stops moving, self-locking is completed.

[0036] Specifically, Figure 3 and Figure 4As shown, the mounting frame 401 is rotatably provided with a rotating cylinder 8 located between the scraper 3 and the cleaning brush 4, the rotating cylinder 8 is provided with two spiral bars 801 distributed in a mirrored manner, the end of the rotating cylinder 8 and the end of the cleaning brush 4 are both provided with pulleys 601, the two pulleys 601 are connected by a belt 602, and the other end of the rotating cylinder 8 or the other end of the cleaning brush 4 is provided with a driving member 6. When the mounting frame 401 is lifted by the adjusting unit, the scraper 3 and the cleaning brush 4 on the mounting frame 401 are both in contact with the conveyor belt. The rotating drum 8 is also provided with a spiral strip 801, and the shaft of the rotating drum 8 has a driving member 6 for driving. The driving member 6 can be an electric motor or a high-power motor. The rotating drum 8 is driven to rotate by the driving member 6, so that the solidified or firmly bonded adhesive material on the conveyor belt can be crushed and scattered by the squeezing of the spiral strip 801. While the driving member 6 is working, it can synchronously drive the cleaning brush 4 to rotate under the action of the belt 602 and the pulley 601, that is, the adhesive material broken up by the spiral strip 801 can be quickly removed by the action of the cleaning brush 4, thereby ensuring the efficiency of cleaning the conveyor belt.

[0037] Based on the above scheme, if Figure 6 As shown, the carrier 2 is provided with a water pipe 10 located on one side of the cleaning brush 4, and the water pipe 10 has a plurality of nozzles for spraying; the pipe of the water pipe 10 is connected to an external pumping device, and the cleaning liquid is transported to the water pipe 10, and the cleaning liquid in the water pipe 10 is sprayed onto the conveyor belt and the cleaning brush 4 through a plurality of nozzles. This can provide moisture during the cleaning process, which helps to soften the materials adhering to the conveyor belt, especially the adhesive materials that have been initially solidified or hardened. At the same time, it can effectively suppress dust flying, improve the working environment, reduce the harm to the health of workers, and also reduce the pollution to the surrounding environment.

[0038] Secondly, the bottom end of the supporting frame 2 has a second material guiding surface 202; since the center line of the supporting frame 2 is at the edge of the discharge hopper, the second material guiding surface 202 is tilted toward one side of the supporting frame 2, that is, tilted toward the outside of the discharge hopper, so as to guide the liquid after cleaning so that the liquid after cleaning will not enter the discharge hopper, thereby ensuring the normal quality of the adhesive material.

[0039] Based on the above scheme, if Figure 5 As shown, the scraper 3 includes a mounting plate 305 and a scraper 301. The mounting plate 305 is fixedly arranged on the corresponding sliding frame 11. The scraper 301 is provided with a limit block 302. The limit block 302 is slidably arranged on the mounting plate 305. The mounting plate 305 is provided with a limit rod 303. The limit block 302 is sleeved on the limit rod 303. The limit rod 303 is sleeved with a return spring 304. The return spring 304 abuts against the bottom end of the limit block 302.

[0040] The scraper 301 is in contact with the conveyor belt. After the scraper 301 initially contacts the conveyor belt, the entire scraper 3 can continue to be lifted upward, so that the scraper 301 is pressed and cannot move. The mounting plate 305 will be compressed by the return spring 304 during its movement. After being compressed to a certain extent, the movement adjustment of the mounting plate 305 is stopped, so that the scraper 301 is always under the pressure of the return spring 304, thereby improving the contact force between the scraper 301 and the conveyor belt, thereby increasing the efficiency of the scraper 301 in scraping off the sticky material on the conveyor belt. In addition, when there is solidified sticky material on the conveyor belt, the scraper 301 can be slightly retreated when encountering greater resistance to avoid damage caused by hard objects or uneven surfaces. At the same time, it automatically returns to its original position after the resistance is reduced, maintaining effective pressure on the conveyor belt, giving the scraper 301 a certain floating space, and better adapting to changes in the conveyor belt surface.

[0041] Specifically, the bottom end of the support frame 2 has a first material guide surface 201; since the center line of the support frame 2 is at the edge of the discharge hopper, the first material guide surface 201 is inclined toward one side of the discharge hopper. When the scraper 301 scrapes off the sticky material on the conveyor belt, the sticky material can fall onto the first material guide surface 201 under the action of gravity, and finally enter the discharge hopper through the guidance of the first material guide surface 201, avoiding accumulation and allowing the sticky material to return to the discharge hopper for utilization.

[0042] Specifically, Figure 6 As shown, both sides of the support frame 2 are bent inward to form a bent edge 9, and a plurality of mounting holes 901 are provided on the bent edge 9. The bent edge 9 can provide a mounting surface for the support frame 2, and the bent edge 9 can be fixedly mounted on the frame of the belt conveyor 1 by passing bolts through the mounting holes 901, thereby completing the fixed installation of the entire device, facilitating assembly, and also facilitating subsequent disassembly and maintenance.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
