Description

Technical Field

[0001] This invention relates to the field of material conveying equipment technology, and in particular to a tracked mobile conveyor with adjustable support height. Background Technology

[0002] Mobile conveyors are key equipment for material transfer in fields such as canals, coal mines, and industrial production. They are especially widely used in coal mines for coal hauling and in canal excavation for crushed stone hauling. Their core function is to enable the rapid discharge of coal hauling and excavated stone hauling.

[0003] For example, application number CN202210100665.4 describes a self-propelled, flexible scraper conveyor, belonging to the field of underground coal mine transportation technology. It addresses the technical problems of low production efficiency and low automation in continuous mining and filling processes. This device includes a tracked walking mechanism and a scraper conveying mechanism. The scraper conveying mechanism is positioned above the tracked walking mechanism. The tracked walking mechanism includes track components and a walking track frame. The track components and the walking track frame bend or move synchronously. The scraper conveying mechanism includes a scraper mechanism and a conveying device. The conveying device drives the scraper mechanism via a circular chain to transport materials from the tail to the head. The scraper mechanism and the conveying device bend or move synchronously. This invention allows free movement in roadways, achieving continuous transportation with 90° horizontal bending. It continuously transports coal mined by the tunneling machine or continuous miner in the continuous mining and filling face to the transport roadway equipment, realizing continuous transportation downstream of the coal mining equipment in the continuous mining and filling face, significantly improving continuous mining efficiency.

[0004] Conveyors similar to those described above also have the following shortcomings: It cannot achieve long-distance, high-angle conveying, and it is inconvenient to adjust when the middle part of the conveyor collapses; after conveying materials, the conveyor belt is prone to leaving dust, debris and other impurities, which will affect the conveying efficiency in the long run and require regular manual cleaning, increasing labor intensity; dust is easily generated during material conveying, which not only pollutes the working environment, but also endangers the health of operators. Summary of the Invention

[0005] This invention relates to a tracked mobile conveyor with adjustable support height, which solves the problems of traditional mobile conveyors being inconvenient for long-distance, high-angle conveying, difficult to clean residual materials on the conveyor belt, and serious dust pollution.

[0006] This invention provides a height-adjustable tracked mobile conveyor, specifically comprising: a first tracked walking mechanism; both the first and second tracked walking mechanisms are placed on the ground, a connecting block is fixed on the first tracked walking mechanism, a connecting frame is hinged to the connecting block, and the connecting frame is welded to the conveyor body; a base is fixed on the second tracked walking mechanism, a first hydraulic cylinder is hinged to the base, the extended end of the first hydraulic cylinder is hinged to the base platform, a connecting seat is hinged to the first hydraulic cylinder, a second hydraulic cylinder is fixed to the connecting seat, and the second hydraulic cylinder is hinged to the base.

[0007] Furthermore, a base is fixed to the bottom surface of the conveyor body, and rollers are symmetrically arranged on the base, with the rollers in contact with the base.

[0008] Furthermore, a limiting block is welded to the bottom end face of the seat, and the limiting block is a front and rear limiting component of the roller.

[0009] Furthermore, the base, the first hydraulic cylinder, the platform, the roller, the seat, the connecting seat, the second hydraulic cylinder, and the limiting block together form an adjustment assembly; the conveyor body is provided with a conveyor belt, and the conveyor belt is provided with protrusions at equal intervals.

[0010] Furthermore, a concave seat is welded to the bottom end face of the conveyor body, and spring rods are symmetrically fixed on the concave seat. The protruding ends of the spring rods are all fixed on the cleaning block, and the cleaning block is in contact with the conveyor belt.

[0011] Furthermore, the contact point between the cleaning block and the conveyor belt is a pointed structure.

[0012] Furthermore, a first mounting frame is welded onto the main body of the conveyor, and a collection box is inserted into the first mounting frame. The collection box is located directly below the cleaning block.

[0013] Furthermore, the concave seat, spring rod, cleaning block, first mounting bracket, and collection box together constitute the cleaning assembly; a sliding seat is symmetrically fixed on the conveyor body, a second mounting bracket slides on the sliding seat, and a helical spring for the second mounting bracket to reset to the left is sleeved on the sliding seat.

[0014] Furthermore, the second mounting bracket is symmetrically equipped with suction pipes, which are located above the conveyor belt. Suction holes are equidistantly opened on the suction pipes. A fan is fixed on the conveyor body. The exhaust pipe of the fan is connected to an external filter structure. The air inlet pipe of the fan is connected to the suction pipe. The fan is electrically connected to an external power supply.

[0015] Furthermore, a force-bearing rod is welded to the bottom end face of the second mounting frame, and one end of the force-bearing rod contacts the upper end face of the conveyor belt. The sliding seat, the second mounting frame, the spiral spring, the suction pipe, the fan, the suction hole, and the force-bearing rod together form the purification component. When the conveyor belt moves, the second mounting frame reciprocates under the action of the protrusion.

[0016] This invention provides a tracked mobile conveyor with adjustable support height, which has the following advantages: In terms of adjustment, the tilt adjustment of the conveyor body can be achieved by extending and retracting the first hydraulic cylinder and the second hydraulic cylinder. When the two conveyor bodies are connected, the collapse between the two conveyor bodies can also be adjusted by the first hydraulic cylinder and the second hydraulic cylinder. Moreover, after the two conveyor bodies are spliced ​​together, long-distance conveying at a large elevation angle can be achieved.

[0017] In terms of conveyor belt cleaning and maintenance, the spring rod in the cleaning component always provides elastic pressure to the cleaning block, ensuring that its pointed contact end fits tightly against the surface of the conveyor belt. During the operation of the conveyor belt, residual material debris is automatically scraped off without manual intervention. The scraped material falls directly into the collection box below for centralized collection. The collection box adopts a plug-in design, which is easy to pull out, empty, and clean, effectively reducing material waste and preventing residual material from wearing down the conveyor belt, thus extending the service life of the equipment.

[0018] In terms of optimizing the working environment, this application uses a purification component that generates negative pressure through a fan, absorbing dust generated during the conveying process through equidistant suction holes on the suction pipe. As the conveyor belt moves, the protrusions on it alternately push the force rod, and with the reset action of the spiral spring, drive the second mounting bracket and the suction pipe to move back and forth, greatly expanding the dust absorption range and improving the purification effect. The absorbed dust-laden gas is discharged after being treated by an external filter structure, effectively reducing the dust concentration in the working environment and protecting the health of operators.

[0019] Regarding conveying stability, the equidistant protrusions on the surface of the conveyor belt increase the friction between the material and the conveyor belt, effectively preventing the material from sliding down during inclined conveying and ensuring conveying quality. The limiting blocks in the adjustment assembly limit the rollers in the front and rear, ensuring that the conveyor body is synchronously and smoothly adjusted when the tracked walking mechanism moves, thereby improving the overall operational stability of the equipment.

[0028] Example 1: Please refer to Figures 1 to 9 : This invention proposes a tracked mobile conveyor with adjustable support height, comprising: a first tracked walking mechanism 1; both the first tracked walking mechanism 1 and the second tracked walking mechanism 103 are placed on the ground; a connecting block 101 is fixed on the first tracked walking mechanism 1, and a connecting frame 102 is hinged to the connecting block 101; the hinge between the connecting block 101 and the connecting frame 102 allows for tilt adjustment of the conveyor body 2; the connecting frame 102 is welded to the conveyor body 2; a base 301 is fixed on the second tracked walking mechanism 103. A first hydraulic cylinder 302 is hinged to the base 303, and the extended end of the first hydraulic cylinder 302 is hinged to the base 303. A connecting seat 306 is hinged to the first hydraulic cylinder 302, and a second hydraulic cylinder 307 is fixed on the connecting seat 306. The second hydraulic cylinder 307 is hinged to the base 301. A seat 305 is fixed to the bottom end face of the conveyor body 2. Rollers 304 are symmetrically arranged on the base 303. The rollers 304 are in contact with the seat 305. When adjusting the tilt angle of the conveyor body 2, the first hydraulic cylinder 302 and the second hydraulic cylinder 307 can be driven to extend and retract.

[0029] A limiting block 308 is welded to the bottom surface of the base 305. The limiting block 308 is a front and rear limiting component of the roller 304. When the second track walking mechanism 103 is adjusted back and forth, the limiting block 308 limits the roller 304, which can ensure that the conveyor body 2 follows the adjustment.

[0030] The base 301, the first hydraulic cylinder 302, the base 303, the roller 304, the seat 305, the connecting seat 306, the second hydraulic cylinder 307, and the limiting block 308 together form the adjustment assembly 3; the conveyor body 2 is provided with a conveyor belt 201, and the conveyor belt 201 is provided with protrusions 202 at equal intervals. Under the action of the protrusions 202, the material can be prevented from sliding down during the conveying process, thus ensuring the conveying quality.

[0031] The bottom surface of the conveyor body 2 is welded with a concave seat 401, and spring rods 402 are symmetrically fixed on the concave seat 401. The protruding ends of the spring rods 402 are all fixed on the cleaning block 403. The cleaning block 403 is in contact with the conveyor belt 201. During the rotation of the conveyor belt 201, the cleaning block 403 can scrape off the debris on the conveyor belt 201, eliminating the need for personnel to clean the conveyor belt 201 separately and ensuring the service life of the conveyor belt 201.

[0032] The contact point between the cleaning block 403 and the conveyor belt 201 is a pointed structure, which allows for better scraping of residues on the conveyor belt 201.

[0033] The conveyor body 2 is welded with a first mounting frame 404, and a collection box 405 is inserted into the first mounting frame 404. The collection box 405 is located directly below the cleaning block 403. When the residue on the conveyor belt 201 is scraped off by the cleaning block 403, it will fall directly into the collection box 405 for collection. When the residue in the collection box 405 reaches a certain amount, the collection box 405 can be pulled out from the first mounting frame 404 and dumped.

[0034] The concave seat 401, spring rod 402, cleaning block 403, first mounting bracket 404 and collection box 405 together form the cleaning assembly 4; a sliding seat 501 is symmetrically fixed on the conveyor body 2, a second mounting bracket 502 slides on the sliding seat 501, and a helical spring 503 for the second mounting bracket 502 to reset to the left is sleeved on the sliding seat 501.

[0035] The second mounting bracket 502 is symmetrically equipped with suction pipes 504, which are located above the conveyor belt 201. Suction holes 506 are equidistantly opened on the suction pipes 504, which can expand the suction range of the suction pipes 504. A fan 505 is fixed on the conveyor body 2. The exhaust pipe of the fan 505 is connected to the external filter structure, and the air inlet pipe of the fan 505 is connected to the suction pipe 504. The fan 505 is electrically connected to an external power supply. Dust will be generated during the conveying process. When the fan 505 is started, the suction pipe 504 will absorb the dust and then discharge it into the external filter box for filtration. The filtration can prevent the workers from inhaling the dust-containing gas.

[0036] The second mounting bracket 502 has a force-bearing rod 507 welded to its bottom surface. One end of the force-bearing rod 507 contacts the upper surface of the conveyor belt 201. The sliding seat 501, the second mounting bracket 502, the helical spring 503, the suction pipe 504, the fan 505, the suction hole 506, and the force-bearing rod 507 together form the purification component 5. When the conveyor belt 201 moves, the second mounting bracket 502 reciprocates under the action of the protrusion 202. The reciprocating movement of the suction pipe 504 driven by the second mounting bracket 502 can further expand... The suction range of the suction pipe 504 further improves the purification range of dust-laden gas. The force rod 507 is made of rigid material, while the conveyor belt 201 and the protrusion 202 are made of rubber. When the helical spring 503 is compressed to its limit, the protrusion 202 will inevitably deform, thereby releasing the rightward pull on the force rod 507. At this time, the force rod 507 returns to its original position under the action of the helical spring 503, and so on to achieve reciprocating movement. The contact end between the force rod 507 and the protrusion 202 is set with a hemispherical structure to reduce wear.

[0037] Example 2, based on Example 1, such as Figures 1-8 As shown, protective plates can be welded to both sides of the conveyor body 2. The height of the protective plates is higher than the height of the protrusion 202. During the material conveying process, the protective plates can block the material on both sides of the conveyor belt 201, preventing the material from falling off the edge of the conveyor belt 201. This is especially suitable for conveying scenarios with a large inclination angle, further improving the conveying stability.

[0038] Example 3: Based on Example 1, as follows Figures 1-8As shown, the tracks of the first tracked walking mechanism 1 and the second tracked walking mechanism 103 are both provided with anti-slip patterns, and shock-absorbing springs are added inside the tracked walking mechanism. The two ends of the shock-absorbing springs are connected to the frame and wheel axle of the tracked walking mechanism, respectively. The anti-slip patterns can increase the friction between the track and the ground, prevent the equipment from slipping when operating in muddy or slippery areas, and improve the walking stability. The shock-absorbing springs can absorb the vibration generated when the equipment moves on rough roads, reduce the impact of vibration on the conveyor body 2 and its components, protect the internal structure of the equipment, and reduce the spillage of materials caused by vibration during the conveying process. It is suitable for complex working conditions such as mining and infrastructure construction.

[0039] Example 4: Based on Example 1, as follows Figure 9 As shown, when long-distance conveying is required, another conveyor body 2 and another second tracked walking mechanism 103 can be connected at the conveyor body 2. When a collapse occurs between the two conveyor bodies 2, the adjustment component 3 on the middle second tracked walking mechanism 103 can be driven to make adjustment, thus realizing the adjustment of the collapse between the two conveyor bodies 2.

[0040] The working principle of this embodiment is as follows: The equipment is moved to the work site. Based on the height requirements of the inlet and outlet, the first hydraulic cylinder 302 and the second hydraulic cylinder 307 are controlled to extend and retract. When long-distance conveying is required, another conveyor body 2 and another second tracked walking mechanism 103 can be connected to the conveyor body 2. When a collapse occurs between the two conveyor bodies 2, the adjustment component 3 on the middle second tracked walking mechanism 103 is driven to adjust it. This achieves the adjustment of the collapse between the two conveyor bodies 2, adjusting the tilt height of the conveyor body 2 to a suitable position. If the overall position of the equipment needs to be adjusted, the first tracked walking mechanism 1 and the second tracked walking mechanism 103 are started, moving the equipment to the target position. The limit block 308 ensures that the conveyor body 2 and the tracked walking mechanism move synchronously during the movement. When the conveyor body 2 is started, the conveyor belt 201 begins to run, carrying the material to be conveyed. Material is placed on conveyor belt 201, with protrusions 202 preventing it from sliding down. Simultaneously, fan 505 is started, and purification component 5 begins operation. As conveyor belt 201 moves, protrusions 202 alternately push against force rod 507, causing second mounting bracket 502 to slide back and forth on sliding seat 501. Helical spring 503 assists in resetting, and suction pipe 504 moves with second mounting bracket 502, comprehensively absorbing dust generated during conveying through suction hole 506. Dust-laden gas is transported by fan 505 to external filter structure for filtration and then discharged. During the operation of conveyor belt 201, cleaning block 403 adheres tightly to the surface of conveyor belt 201 under the elastic action of spring rod 402, and the pointed contact end scrapes off residual material. The scraped material falls into collection box 405 below. After the operation is completed, the equipment power is turned off, collection box 405 is pulled out from first mounting bracket 404, residual material is emptied and cleaned, completing the entire operation process.

[0041] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. The scope of protection of this disclosure shall be determined by the scope of the claims.
