Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for belt conveyors, specifically relating to a device for cleaning mud and powder from sand and gravel on an inclined belt. Background Technology

[0002] In sand and gravel conveying operations, due to the inclined conveying characteristics of inclined belt conveyors, mud and powder carried in the sand and gravel easily adhere to the surface of the conveyor belt. If not cleaned in time, it will not only cause an imbalance in the friction between the belt and the drive wheel, affecting the conveying efficiency, but also cause belt misalignment and accelerated wear due to mud and powder accumulation, shortening the service life of the equipment. At the same time, the residual mud and powder may contaminate the sand and gravel conveyed later, reducing the purity of the material.

[0003] The scraper thrust of the existing cleaning device is a fixed value and cannot be adjusted according to the actual working conditions. If the scraper is too loosely attached to the conveyor belt, mud and powder will remain and the cleaning will not be thorough; if the attachment is too tight, the belt will wear excessively due to excessive friction, increasing maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a device for cleaning mud and powder from sand and gravel on an inclined belt. This device can complete the cleaning of the inclined belt during the operation of the belt conveyor, and ensure that the scraper can closely contact the inclined belt to guarantee the cleaning effect and reduce the wear and damage to the inclined belt caused by the large friction between the scraper and the inclined belt.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A device for cleaning mud and powder from sand and gravel on an inclined belt includes a lower frame, two upper frames are fixedly connected to the upper side of the lower frame, an elastic push bracket is fixedly connected between the two upper frames, and a scraper is installed on the upper side of the elastic push bracket.

[0007] The elastic pusher bracket is used to apply an upward elastic thrust to the scraper, and the magnitude of the elastic thrust is adjustable.

[0008] Furthermore, the elastic push bracket includes a cross frame and two threaded rods. The two threaded rods are respectively fixedly connected to two upper side frames. Each end of the cross frame has a first circular hole. The two threaded rods are respectively inserted into the two first circular holes. A nut is threadedly connected to the outer side of the threaded rod at the lower side of the cross frame. A return spring is installed between the nut and the cross frame. The return spring is sleeved on the outer side of the threaded rod.

[0009] Furthermore, the horizontal cross-section of the scraper is a broken line shape.

[0010] Furthermore, a carriage is horizontally slidably connected to the upper side of the cross frame, the scraper is fixedly connected to the upper side of the carriage, and a reciprocating drive mechanism that is connected to the carriage is fixedly connected to the cross frame.

[0011] Furthermore, the reciprocating drive mechanism includes a servo motor fixedly connected to the lower side of the cross frame. The output end of the servo motor is driven by a drive shaft, which is rotatably connected to the lower side of the cross frame. A guide groove is provided on the drive shaft. A round rod is fixedly connected to the lower side of the slide. A straight groove is provided on the cross frame. The lower end of the round rod extends through the straight groove into the interior of the guide groove.

[0012] Furthermore, a pressure plate located on the upper side of the scraper is also fitted on the outer side of the two threaded rods.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-7 As shown, a device for cleaning mud and powder from sand and gravel on an inclined belt includes a lower frame 1. Two upper frames 2 are fixedly connected to the upper side of the lower frame 1. An elastic push bracket is fixedly connected between the two upper frames 2. A scraper 10 is installed on the upper side of the elastic push bracket. The elastic push bracket is used to apply an upward elastic thrust to the scraper 10, and the magnitude of the elastic thrust is adjustable.

[0028] In use, the device is fixedly connected to the bottom of the belt conveyor, so that the scraper 10 of the device is located below the conveyor belt 15. At this time, under the elastic thrust of the elastic push bracket, the upper edge of the scraper 10 can be sealed against the outer side of the conveyor belt 15. During the movement of the conveyor belt 15, the scraper 10 can scrape off the sand, gravel and mud adhering to the conveyor belt 15, thereby completing the cleaning work of the conveyor belt 15 during the operation of the belt conveyor. By adjusting the elastic thrust applied to the scraper 10, the scraper 10 can be tightly against the conveyor belt 15 to ensure the cleaning effect of the conveyor belt 15 and reduce the wear damage to the conveyor belt 15 caused by the large friction between the scraper 10 and the conveyor belt 15.

[0029] In this case, the side of the inclined conveyor belt 15 used to place sand and gravel during operation is the outer side of the inclined conveyor belt 15, and the other side of the inclined conveyor belt 15 is the inner side of the inclined conveyor belt 15.

[0030] like Figures 1-3 As shown, the elastic push support includes a crossbeam 6 and two threaded rods 3. The two threaded rods 3 are fixedly connected to two upper side frames 2 respectively. The two ends of the crossbeam 6 are provided with first circular holes. The two threaded rods 3 are respectively inserted into the two first circular holes. Nuts 4 are threadedly connected to the outer side of the threaded rods 3 at the lower side of the crossbeam 6. A return spring 5 is installed between the nut 4 and the crossbeam 6. The return spring 5 is sleeved on the outer side of the threaded rod 3. The return spring 5 can apply an upward elastic thrust to the crossbeam 6, thereby transmitting the elastic thrust to the scraper 10 through the crossbeam 6. The elastic thrust applied to the crossbeam 6 by the return spring 5 can be adjusted by rotating the nut 4.

[0031] In some embodiments, the scraper 10 can be a rectangular plate, and the scraper 10 can be directly fixed to the upper side of the cross frame 6.

[0032] In other embodiments, the horizontal cross-section of the scraper 10 is a broken line. In this case, the scraper 10 is composed of multiple inclined plates. When the mud powder on the outside of the conveying inclined belt 15 comes into contact with the inclined plates, it will be pushed by the inclined plates to move obliquely. The multiple inclined plates form a shearing force, thereby forming a shearing force to better clean the mud powder and improve the mud powder stripping efficiency.

[0033] like Figures 2-5 As shown, in some embodiments, a slide 9 is horizontally slidably connected to the upper side of the cross frame 6, and a scraper 10 is fixedly connected to the upper side of the slide 9. A reciprocating drive mechanism that is connected to the slide 9 is fixedly connected to the cross frame 6 and is used to drive the slide 9 to move left and right on the upper side of the cross frame 6. When the slide 9 drives the scraper 10 to move left and right, the scraper 10 moving left and right will clean the mud powder on the outside of the conveyor belt 15.

[0034] The reciprocating drive mechanism can be an electric push rod fixedly connected to the crossbeam 6, and the piston rod of the electric push rod is fixedly connected to the scraper 10.

[0035] Among them, such as Figures 3-7 As shown, another structure of the reciprocating drive mechanism is disclosed here. The reciprocating drive mechanism includes a servo motor 7 fixedly connected to the lower side of the cross frame 6. The output end of the servo motor 7 is driven by a drive shaft 8. The drive shaft 8 is rotatably connected to the lower side of the cross frame 6. A guide groove 21 is provided on the drive shaft 8. A round rod 22 is fixedly connected to the lower side of the slide 9. A straight groove 20 is provided on the cross frame 6. The lower end of the round rod 22 extends through the straight groove 20 into the interior of the guide groove 21. At this time, the servo motor 7 drives the drive shaft 8 to rotate, and the guide groove 21 pushes the round rod 22 to move the slide 9. The guide groove 21 is preferably an elliptical track inclinedly set on the outside of the drive shaft 8. When the drive shaft 8 rotates one revolution, the guide groove 21 can drive the round rod 22 to move back and forth once.

[0036] like Figures 2-4 In order to make the outer side of the conveyor belt 15 and the upper side of the scraper 10 more closely contact, a pressure plate 11 located on the upper side of the scraper 10 is also installed on the outer side of the two threaded rods 3. The two ends of the pressure plate 11 are provided with second round holes. The two threaded rods 3 are respectively inserted into the two second round holes. Another return spring 5 located on the upper side of the pressure plate 11 is sleeved on the outer side of the threaded rod 3. Another nut 4 is installed on the upper end of the other return spring 5. The nut 4 is threaded to the outer side of the threaded rod 3. By rotating the other nut 4, the force applied to the conveyor belt 15 by the pressure plate 11 can be adjusted. By pressing the conveyor belt 15 by the pressure plate 11, the conveyor belt 15 can make close contact with the scraper 10.

[0037] Meanwhile, a rotating shaft bracket 12 can be fixedly connected to the lower side of the pressure plate 11. Two rotating shaft bodies 13 are rotatably connected to the lower side of the rotating shaft bracket 12. A pressure belt 14 is connected to the outer side of the two rotating shaft bodies 13. The pressure belt 14 drives the pressure plate 11 to contact the conveyor belt 15, which can reduce the wear and damage to the inner side of the conveyor belt 15 and the pressure plate 11.

[0038] Among them, such as Figures 1-2 As shown, a collection hopper 16 located outside the scraper 10 is fixedly connected between the two upper frames 2. The upper height of the collection hopper 16 is lower than the upper height of the scraper 10, so that the upper side of the collection hopper 16 does not contact the conveyor belt 15. The sand, gravel and mud powder cleaned by the scraper 10 will fall into the collection hopper 16 and then be stored through the discharge port at the lower end of the collection hopper 16.

[0039] A guide rail 18 is fixedly connected to the lower side of the lower frame 1. A trolley 19 is slidably connected to the guide rail 18. A brake pad or a snap-on brake mechanism can be installed on the trolley 19 to limit the movement of the trolley 19. A storage box 17 is fixedly connected to the upper side of the trolley 19. When the scraper 10 cleans the conveyor belt 15, the trolley 19 moves the storage box 17 to the lower side of the hopper 16, so that the sand and gravel discharged from the hopper 16 fall into the storage box 17 for storage. When discharging the sand and gravel and gravel from the storage box 17, the trolley 19 can be slid to move the storage box 17 away from the lower side of the conveyor belt 15. This reduces the impact on the operator from the conveyor belt 15 when discharging the sand and gravel and gravel from the storage box 17.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
