Description

Technical Field

[0001] This utility model relates to a small ore material handling device, specifically a small ore material handling device for open-pit mining, belonging to the field of mining transportation technology. Background Technology

[0002] Small-scale ore material handling equipment for open-pit mining refers to small transport vehicles suitable for short-distance transfer of bulk materials such as ore and waste rock in open-pit mines. Curved rail side-discharge mine cars are a common type. They are usually composed of a car body, frame, wheelset, unloading wheel arm, and matching curved rail. The car body is mostly steel bucket-shaped to hold materials. One side is hinged to the frame, and the other side is equipped with an unloading wheel arm. The frame connects the car body and the wheelset to ensure the stability of the equipment when it moves. Its working principle is as follows: when the mine car travels along the track to the unloading point, the unloading wheel arm enters the preset curved rail. As the mine car continues to move, the curved rail drives the car body to tilt around the hinge axis through the wheel arm, so that the material is automatically unloaded from the side. After unloading, the wheel arm disengages from the curved rail, and the car body returns to its original position under the action of gravity. This equipment is suitable for open-pit mining scenarios with limited space and requiring efficient automatic unloading, and can realize continuous loading, transportation, and unloading operations.

[0003] However, existing curved track side-discharge mining cars rely solely on the gravity of the tilted car body for unloading. When encountering materials with high viscosity, high moisture content, or fine particle size, material residue easily adheres to the inside of the car body and is difficult to remove completely. Therefore, manual assistance is required to clean the inside of the car body, which increases operating costs and labor intensity. Utility Model Content

[0004] The purpose of this invention is to provide a small-scale ore material handling device for open-pit mining in order to solve the above-mentioned problems. By setting a cleaning structure on the carriage, a large area of ​​residual ore material can be scraped off from the bottom plate of the carriage after unloading using a scraper. At the same time, a cleaning brush rolls against the inner wall of the carriage to automatically remove the ore material residue adhering to the inner wall. Therefore, no manual cleaning is required, which can solve the problem of ore residue with high viscosity, high moisture or fine particle size, thereby reducing operating costs and labor intensity.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a small ore material handling device for open-pit mining, comprising a frame, a carriage rotatably connected to the frame, a cleaning structure installed on the carriage, the cleaning structure including guide rails, two guide rails installed at the top of the carriage, sliders slidably connected within the guide rails, a mounting frame fixedly connected between the two sliders, a scraper provided at the bottom of the mounting frame, the scraper slidably connected to the carriage, cleaning brushes rotatably connected to both ends of the mounting frame facing the inner wall of the carriage, the cleaning brushes rolling and abutting against the inner wall of the carriage, a unloading structure installed on the carriage, and a side door rotatably connected to the side of the carriage hinged to the frame, a dust suppression structure installed on the side door.

[0006] Preferably, the slider has an "L" shaped cross-section, and the scraper has an arc-shaped cross-section.

[0007] Preferably, the top end of the guide rail is provided with a first hydraulic rod, the extended end of the first hydraulic rod is fixedly connected to a connecting rod, and the end of the connecting rod is fixedly connected to the slider.

[0008] Preferably, a second hydraulic rod is rotatably connected to the side door, and the extended end of the second hydraulic rod is rotatably connected to the carriage.

[0009] Preferably, the unloading structure includes a rotating base, with rotating bases fixedly connected to both ends of the frame, a sliding rod rotatably connected to the rotating base, and a sliding sleeve fixedly connected to the carriage, with the sliding rod and the sliding sleeve slidably connected.

[0010] Preferably, the top of the slide bar has a "T" shape, and the side of the carriage away from the hinged side with the frame is equipped with unloading wheels.

[0011] Preferably, the dust suppression structure includes a pipe, and a pipe is installed at the bottom end of the side door, with multiple nozzles arranged in a linear array on the pipe.

[0012] Preferably, a water tank is installed on the side wall of the side door, and a flexible hose is installed at the bottom of the water tank, with the bottom end of the flexible hose being fixedly connected to a pipe.

[0013] The beneficial effects of this utility model are as follows: A carriage is rotatably connected to the frame, and two guide rails are installed at the top of the carriage. Sliding blocks are slidably connected inside the guide rails, and a mounting frame is fixedly connected between the two sliding blocks. A scraper is provided at the bottom of the mounting frame, and the scraper is slidably connected to the carriage. Cleaning brushes are rotatably connected to both ends of the mounting frame facing the inner wall of the carriage, and the cleaning brushes roll against the inner wall of the carriage in a rolling contact action. By setting a cleaning structure on the carriage, after unloading, a large area of ​​residual mineral material on the carriage floor can be scraped off by the scraper, while the cleaning brushes roll against the inner wall of the carriage to automatically remove the mineral material residue adhering to the inner wall. Therefore, no manual cleaning is required, which can solve the problem of residue of highly viscous, highly moist, or fine-particle mineral material, thereby reducing operating costs and labor intensity.

[0021] 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.

[0022] Please see Figures 1-6 As shown, a small ore material handling device for open-pit mining includes a frame 1, a carriage 2 rotatably connected to the frame 1, a cleaning structure 3 installed on the carriage 2, the cleaning structure 3 including guide rails 301, two guide rails 301 installed at the top of the carriage 2, sliders 302 slidably connected inside the guide rails 301, a mounting frame 303 fixedly connected between the two sliders 302, a scraper 304 provided at the bottom of the mounting frame 303, the scraper 304 slidably connected to the carriage 2, cleaning brushes 305 rotatably connected to both ends of the mounting frame 303 facing the inner wall of the carriage 2, the cleaning brushes 305 rollingly contacting the inner wall of the carriage 2, a unloading structure 6 installed on the carriage 2, a side door 4 rotatably connected to the side of the carriage 2 hinged to the frame 1, a dust suppression structure 7 installed on the side door 4.

[0023] As a technical optimization of this utility model, the cross-section of the slider 302 is L-shaped, which increases the stability of the slider 302 when sliding. The cross-section of the scraper 304 is arc-shaped, which can better fit the bottom plate of the carriage 2, reduce the dead corners of scraping, and thus improve the scraping rate of the ore. The top of the guide rail 301 is provided with a first hydraulic rod 306. The extended end of the first hydraulic rod 306 is fixedly connected to a connecting rod 307. The end of the connecting rod 307 is fixedly connected to the slider 302. The first hydraulic rod 306 extends or retracts, and drives the slider 302 to slide along the guide rail 301 through the connecting rod 307, thereby driving the mounting frame 303, scraper 304, and cleaning brush 305 to complete the cleaning action.

[0024] As a technical optimization of this utility model, a second hydraulic rod 5 is rotatably connected to the side door 4. The extended end of the second hydraulic rod 5 is rotatably connected to the carriage 2. By extending or retracting, the second hydraulic rod 5 drives the side door 4 to rotate relative to the carriage 2, thereby realizing the adjustment of opening and closing of the side door 4.

[0025] As a technical optimization of this utility model, the unloading structure 6 includes a rotating seat 602. The rotating seat 602 is fixedly connected to both ends of the frame 1. A sliding rod 603 is rotatably connected to the rotating seat 602. A sliding sleeve 604 is fixedly connected to the carriage 2. The sliding rod 603 and the sliding sleeve 604 are slidably connected. The top of the sliding rod 603 has a "T" shaped structure. An unloading wheel 601 is installed on the side of the carriage 2 away from the hinge side with the frame 1. The unloading wheel 601, in conjunction with the curved rail, drives the carriage 2 to tilt around the hinge side to achieve unloading. The sliding cooperation of the rotating seat 602, the sliding rod 603 and the sliding sleeve 604 helps to stabilize the tilting process of the carriage 2 and ensures smooth and safe unloading.

[0026] As a technical optimization of this utility model, the dust suppression structure 7 includes a pipe 701. The pipe 701 is installed at the bottom of the side door 4. Multiple nozzles 702 are arranged in a linear array on the pipe 701. A water tank 703 is installed on the side wall of the side door 4. A hose 704 is installed at the bottom of the water tank 703. The bottom of the hose 704 is fixedly connected to the pipe 701. The dust suppression structure 7 supplies water to the pipe 701 at the bottom of the side door 4 through the water tank 703 and the hose 704. The water is then sprayed out by the nozzles 702 on the pipe 701, thereby achieving dust suppression during the unloading process.

[0027] In use, when loading ore, the side door 4 is initially closed and stabilized by the extension of the second hydraulic rod 5. The ore is then loaded into the car body 2, and a traction locomotive (such as an electric locomotive or winch) pulls the car body to the unloading pit. As the car body moves along the track, the unloading wheel 601 on the side away from the hinged end of the car body 2 enters the curved track, causing the car body 2 to tilt around the hinge axis with the frame 1. Simultaneously, the sliding rods 603 on the rotating seats 602 at both ends of the frame 1 slide within the sliding sleeves 604 of the car body 2. The top of the sliding rod 603... The "T"-shaped structure prevents the slide rod 603 from slipping out of the sliding sleeve 604, thus assisting in the stable tilting of the carriage 2. Simultaneously, the second hydraulic rod 5 is activated, retracting to rotate the side door 4 around its axis of rotation with the carriage 2 until the side door 4 rotates upwards by ninety degrees and becomes perpendicular to the carriage 2, no longer obstructing the unloading port of the carriage 2, allowing the ore inside the carriage 2 to be discharged through the unloading port. After unloading is completed, the cleaning structure 3 begins operation: the first hydraulic rod 306 is activated, extending through the connecting rod 30... 7 drives the "L"-shaped slider 302 inside the guide rail 301 to slide, thereby causing the mounting bracket 303 between the two sliders 302 to move along the top of the carriage 2. At this time, the arc-shaped scraper 304 at the bottom of the mounting bracket 303 slides along the bottom plate of the carriage 2, thereby scraping off a large area of ​​residual mineral material on the bottom plate. At the same time, the cleaning brushes 305 at both ends of the mounting bracket 303 rotate against the inner wall of the carriage 2 in a rolling contact manner, thereby removing the fine mineral material adhering to the inner wall of the carriage 2, thus achieving a comprehensive cleaning of the interior of the carriage 2. After cleaning is completed, the first hydraulic rod 3... 06 retracts, causing the mounting frame 303, scraper 304, and cleaning brush 305 to reset and fit against the inner wall of the car body 2. Then, the mine car prepares to enter the next loading and transportation cycle. During the unloading process, the dust suppression structure 7 is activated through the control terminal. The water in the water tank 703 is pressurized by the high-pressure pump at its bottom and flows into the pipe 701 at the bottom of the side door 4 through the hose 704. Then, the water is sprayed into a mist-like water flow towards the unloading port of the car body 2 through the linear array of nozzles 702 on the pipe 701, thereby effectively suppressing the dust generated during ore unloading and reducing environmental pollution.
