Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology, and in particular relates to a mobile belt conveyor. Background Technology

[0002] Mobile belt conveyors are continuous conveying equipment equipped with wheeled or tracked chassis. They are characterized by high efficiency, flexibility and high mobility. Their core function is to facilitate flexible relocation and quickly switch working positions through wheel sets, enabling short-distance transfer of bulk materials in scenarios such as mines and ports.

[0003] Existing mobile belt conveyors still have some problems during use. For example, traditional movable wheels do not have a rigid locking structure and rely only on friction braking. After the equipment is in place, the wheel set is prone to displacement due to the impact of materials, which causes the conveyor belt to run off-track, resulting in material spillage and belt wear. In addition, materials are easy to stick to the surface of the conveyor belt, which reduces the conveying efficiency. To address these issues, we provide a mobile belt conveyor to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a mobile belt conveyor that solves the problem of existing mobile belt conveyors having no rigid locking structure for the movable wheels, relying only on friction braking, and the wheel set easily displacing due to material impact after the equipment is in place. This is achieved through the cooperation of the moving mechanism and the scraping mechanism.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a mobile belt conveyor, comprising a conveyor, a mobile box fixedly connected to the bottom of the conveyor, a drive mechanism inside the mobile box, a moving mechanism on one side inside the mobile box, and a scraping mechanism on the other side inside the mobile box. The moving mechanism includes a push plate on one side inside the mobile box, a scraping plate on the other side inside the mobile box, a directional wheel movably connected to the bottom of the push plate via a bearing, and support plates fixedly connected to both sides of the bottom of the mobile box. The scraping mechanism includes an extension tube fixedly connected to the top of the scraping plate, a first spring inside the extension tube, an extension rod fixedly connected to the top of the first spring, and a brush plate movably connected to the top of the extension rod via a rotating shaft.

[0007] The present invention is further configured such that the driving mechanism includes a gear assembly disposed inside the movable box, a screw movably connected inside the movable box via a bearing, a threaded sleeve threaded to the surface of the screw, a movable plate fixedly connected to one side of the threaded sleeve, and a movable wheel fixedly connected to one side of the movable plate.

[0008] The present invention is further configured such that the gear assembly includes a driven bevel gear fixedly connected to one end of the screw, and a driving bevel gear meshing with the driven bevel gear, and a dual-shaft motor is fixedly connected to one side of the driving bevel gear.

[0009] The present invention is further configured such that there are two screws and two screw sleeves, and the thread directions of the two screws are opposite, and the screw sleeves are asymmetrically arranged on the screw surfaces.

[0010] The present invention is further configured such that a vertical rod is fixedly connected inside the movable box, and both the push plate and the scraper plate have vertical through holes adapted to the vertical rod, and a second spring is sleeved on the surface of the vertical rod.

[0011] The present invention is further configured such that a crossbar is fixedly connected inside the movable box, a limit block is slidably connected to the surface of the crossbar, and a triangular plate is fixedly connected to one side of both the push plate and the scraper plate.

[0012] The present invention is further configured such that a hydraulic cylinder is fixedly connected inside the movable box, a limit plate is fixedly connected to the output end of the hydraulic cylinder, an anti-movement plate is fixedly connected inside the movable box, and a limit slot adapted to the limit plate is opened inside the anti-movement plate, the push plate and the scraping plate.

[0013] The present invention is further configured such that a positioning plate is fixedly connected inside the mobile box, and inlet and outlet slots are provided at the top and bottom of the mobile box.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a dual-axis motor to drive an active bevel gear to mesh with a driven bevel gear, which in turn drives two screws with opposite threads to rotate synchronously. This causes the screw sleeve to push the moving plate to move laterally, and the moving wheel to press against the triangular plate, pushing the push plate and scraper plate to move outward symmetrically. The directional wheel extends out and contacts the ground. The reverse thread design ensures the synchronous movement of the push plate and the scraper plate. When the directional wheel retracts into the moving box, the support plate forms a rigid contact with the ground. This process achieves precise retraction and extension of the wheel set through mechanical linkage, solving the problem of wheel set displacement caused by traditional friction braking and avoiding conveyor belt deviation and material spillage.

[0016] 2. In this utility model, when the scraper moves outward, it drives the extension tube to move upward, and the extension rod lifts the brush plate to move upward. This allows the brush plate to adaptively fit the belt tilt angle through the rotating shaft. The first spring extends and retracts to compensate for the undulations of the belt surface, ensuring continuous contact of the brush plate. At the same time, the scraping mechanism will only move upward to work after the moving mechanism retracts the direction wheel, avoiding motion interference. This linkage design allows the brush plate to adapt to the changes in belt shape, effectively scraping off sticky materials, improving conveying efficiency and reducing belt wear.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0027] Please see Figures 1-5 This utility model is a mobile belt conveyor, including a conveyor 1, a mobile box 2 fixedly connected to the bottom of the conveyor 1, a drive mechanism 3 inside the mobile box 2, the drive mechanism 3 being configured to synchronously drive the moving mechanism 4 and the scraping mechanism 5 to move in linkage, the moving mechanism 4 being provided on one side inside the mobile box 2, and the scraping mechanism 5 being provided on the other side inside the mobile box 2, the moving mechanism 4 including a push plate 401 provided on one side inside the mobile box 2, a scraping plate 402 provided on the other side inside the mobile box 2, a directional wheel 403 movably connected to the bottom of the push plate 401 via a bearing, and a support plate 404 fixedly connected to both sides of the bottom of the mobile box 2, the scraping mechanism 5 including an extension tube 501 fixedly connected to the top of the scraping plate 402, a first spring 502 provided inside the extension tube 501, an extension rod 503 fixedly connected to the top of the first spring 502, and a brush plate 504 movably connected to the top of the extension rod 503 via a rotating shaft.

[0028] Specifically, through the setting of the moving mechanism 4, the dual-axis motor 6 drives the active bevel gear 3012 to mesh with the driven bevel gear 3011, driving the two reverse-threaded screws 302 to rotate synchronously. The screw sleeve 303 pushes the moving plate 304 to move laterally, and the moving wheel 305 presses the triangular plate 11 to push the push plate 401 and the scraper plate 402 to move outward. The directional wheel 403 extends out of the moving box 2 and contacts the ground. The reverse-threaded screws 302 realize the synchronous and symmetrical movement of the push plate 401 and the scraper plate 402, ensuring the stable extension / retraction of the directional wheel 403. After the moving box 2 is inside, the support plates 404 on both sides contact the ground to prevent displacement. With the setting of the scraping mechanism 5, when the scraping plate 402 moves outward, it drives the extension tube 501 to move synchronously. The brush plate 504 is continuously lifted under the action of the extension rod 503. The brush plate 504 adapts to the belt tilt angle through the rotating shaft. The extension and contraction of the first spring 502 makes the brush plate 504 adapt to the undulation of the belt surface. After the moving mechanism 4 moves to the designated position, it retracts the direction wheel 403 to prevent it from shaking. The scraping mechanism 5 adapts to the belt tilt angle and brushes off the material sticking to the belt surface. Specific Implementation Example 2

[0030] Please see Figures 1-5Based on the first specific embodiment, the drive mechanism 3 includes a gear assembly 301 disposed inside the movable box 2, a screw 302 movably connected inside the movable box 2 via bearings, a threaded sleeve 303 threadedly connected to the surface of the screw 302, a movable plate 304 fixedly connected to one side of the threaded sleeve 303, and a movable wheel 305 fixedly connected to one side of the movable plate 304. The gear assembly 301 includes a driven bevel gear 3011 fixedly connected to one end of the screw 302, and a driving bevel gear 3012 meshing with the driven bevel gear 3011. A dual-axis motor 6 is fixedly connected to the side, and the dual-axis motor 6 is fixedly connected inside the movable box 2. The dual-axis motor 6 is used to drive the rotation of the active bevel gear 3012, which is existing technology and will not be described in detail here. Moreover, those skilled in the art can clearly understand the working principle. There are two screws 302 and two screw sleeves 303, and the thread directions on the surfaces of the two screws 302 are opposite. The screw sleeves 303 are asymmetrically arranged on the surfaces of the screws 302. A vertical rod 7 is fixedly connected inside the movable box 2. The push plate 401 and the scraper plate 402 both have vertical through holes adapted to the vertical rod 7. There are four rods 7, arranged in pairs, each set in a vertical through hole inside the push plate 401 and scraper plate 402. A second spring 8 is fitted onto the surface of each vertical rod 7. A horizontal rod 9 is fixedly connected inside the moving box 2, and a limit block 10 is slidably connected to the surface of the horizontal rod 9. One side of the limit block 10 is fixedly connected to the moving plate 304. Triangular plates 11 are fixedly connected to one side of both the push plate 401 and the scraper plate 402, near the moving wheel 305. A hydraulic cylinder 12 is fixedly connected inside the moving box 2. The hydraulic cylinder 12 is used for... The movement of the driving limit plate 13 is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle. The output end of the hydraulic cylinder 12 is fixedly connected to the limit plate 13. The inside of the moving box 2 is fixedly connected to the anti-movement plate 14. The anti-movement plate 14, the push plate 401 and the scraper plate 402 are all provided with limit slots that are compatible with the limit plate 13. The inside of the moving box 2 is fixedly connected to the positioning plate 15. The top and bottom of the moving box 2 are provided with inlet and outlet through slots. There are two support plates 404. The left support plate 404 is movably connected to the auxiliary wheel through the bearing.

[0031] Specifically, the drive mechanism 3 is used to move the moving plate 304. The gear assembly 301 is used to transmit the power of the dual-shaft motor 6 to the screw 302. The two sets of screw sleeves 303 are used to drive the push plate 401 and the scraper plate 402 to move towards each other. With the opposite threads and asymmetrical sleeves 303, the scraper plate 402 is in a low position when the direction wheel 403 moves out, and the brush plate 504 is not in contact with the conveyor belt. When the scraper plate 402 moves up and drives the brush plate 504 to contact the conveyor belt, the direction wheel 403 retracts into the moving box 2 to prevent the moving box 2 from moving. With the vertical rod 7 and the second spring 8, after the driving power is lost, the push plate 401 and the scraper plate 402 are reset by the reset action of the second spring 8. With the horizontal rod 9 and the limiting block 10, the limiting block 10 is... The side provides support to allow the limit block 10 to move smoothly, while limiting the screw sleeve 303 to prevent it from rotating during movement. The triangular plate 11, in conjunction with the moving wheel 305, continuously drives the push plate 401 and scraper plate 402 to move. The hydraulic cylinder 12 is used to drive the limit plate 13 to move. The anti-movement plate 14 and the limiting through groove ensure that after the push plate 401 and scraper plate 402 reach the designated position, the limit plate 13 is inserted into the limiting slot to prevent the push plate 401 and scraper plate 402 from moving. The positioning plate 15 supports and positions the push plate 401 and scraper plate 402 when they are retracted. The in-and-out through groove allows the directional wheel 403 to smoothly enter and exit the moving box 2. The auxiliary wheel assists the left side of the bottom of the moving box 2 to move during the movement.

[0032] The operation process of this embodiment is as follows: When movement is required, the dual-axis motor 6 is started by the external controller. The dual-axis motor 6 rotates forward, and drives the two screws 302 with opposite threads to rotate synchronously through the gear assembly 301, which drives the screw sleeve 303 to move laterally. The screw sleeve 303 pushes the moving plate 304 and the moving wheel 305 to move. The moving wheel 305 presses the triangular plate 11 to make the push plate 401 move down. The push plate 401 drives the directional wheel 403 to extend out of the moving box 2 and contact the ground. At this time, the scraper plate 402 remains in a low position so that the brush plate 504 is disengaged from the belt. The operator pulls the conveyor 1 to the target work position to complete the equipment transfer.

[0033] Then, the dual-axis motor 6 reverses, and the screw 302 rotates in the opposite direction to reset the push plate 401 and retract the direction wheel 403. At the same time, the screw sleeve 303 drives the scraper plate 402 to move upward. The scraper plate 402 lifts the extension rod 503 through the extension tube 501, so that the brush plate 504 is in contact with the lower surface of the belt. The first spring 502 and the rotating shaft adaptively compensate for the belt tilt angle and undulation, and continuously scrape off the sticky material. The hydraulic cylinder 12 pushes the limit plate 13 to insert into the limit slot, locks the position of the scraper plate 402, and the support plate 404 forms a rigid ground to ensure stable operation of the equipment. During the movement of the conveyor belt, the brush plate 504 brushes off the material sticking to the surface of the conveyor belt.
