Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for mining dump trucks, specifically to a stone remover for mining dump trucks. Background Technology

[0002] In mining operations, mining dump trucks bear the heavy responsibility of transporting materials such as ore and soil. Their working environment is harsh, with rugged roads filled with debris, including rocks, which pose a significant safety hazard. If a mining dump truck's tires run over large or sharp rocks, it can cause uneven stress on the tires, leading to a tire blowout. Furthermore, if rocks enter critical components such as the vehicle's chassis transmission parts and suspension system, they will accelerate wear and tear, increasing equipment failure rates. Therefore, rock removers are crucial for ensuring vehicle safety and improving work efficiency.

[0003] Currently, the common practice for removing stones from mining dump trucks is to use plate-type stone ejectors. These are made of high-strength metal plates and are fixed to the vehicle chassis near the tires using a specific connection method. The rigidity and scraping action of the metal plates remove stones from the tires or the road surface. During operation, as the vehicle moves, the metal plates of the ejector come into contact with the stones, and the continuous scraping force removes the stones from the tires or the road surface, thus achieving the stone removal function. While this method can remove some stubborn stones, it is incomplete, inefficient, labor-intensive, and prone to tire damage, making it difficult to meet the needs of large-scale, high-efficiency mining operations. During peak transportation periods in large mines, manual stone removal is far less efficient than the operation of mining dump trucks, resulting in excessively long vehicle waiting times and severely impacting production efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a stone remover for mining dump trucks. It aims to solve the problems of incomplete stone removal and easy tire damage of existing stone removers for mining dump trucks, achieve efficient removal of stones of various sizes and shapes, ensure that the tires of mining dump trucks are not squeezed, scratched and impacted by stones during driving, extend tire service life, reduce vehicle failure rate, improve the safety and transportation efficiency of mining dump trucks, and enhance their adaptability and reliability in harsh mining environments.

[0005] The purpose of this utility model is achieved as follows: A rock remover for a mining dump truck includes a mounting base, a connecting beam, a rock remover scraper connecting bracket, a rock remover scraper, a limiting baffle, and a limiting spring. One end of the connecting beam is connected to the mounting base, and the other end is connected to the rock remover scraper connecting bracket. The rock remover scraper scraper is hinged to the center of the rock remover scraper connecting bracket, and limiting baffles are symmetrically installed on both sides. A limiting spring is provided between the rock remover scraper and the limiting baffle.

[0006] Preferably, the height of the connecting beam is adjustable, and the bottom of the mounting base is provided with a height adjustment mechanism. The height adjustment mechanism includes an adjusting screw, an adjusting nut, and an adjusting top plate. The adjusting nut is fixed to the horizontal sealing plate of the mounting base, the adjusting screw passes through the adjusting nut and connects to the adjusting top plate, and the adjusting top plate abuts against the bottom of the connecting beam on the side of the mounting base.

[0007] Preferably, the mounting base is a welded component, including a frame connecting plate, mounting ear plates, and a horizontal sealing plate. The frame connecting plate is used to fix it to the chassis frame. Mounting bolts are evenly distributed around the perimeter of the frame connecting plate. The vertically arranged frame connecting plate connects to the horizontal sealing plate. The mounting ear plates are connected to both the frame connecting plate and the horizontal sealing plate. The two mounting ear plates are arranged left and right. One end of the connecting beam is clamped between the two mounting ear plates and connected by fastening bolts. The mounting ear plates have vertical grooves corresponding to the fastening bolts.

[0008] Preferably, the two limiting springs are arranged symmetrically on the left and right, with one end of the limiting spring fixed to the stone removal scraper and the other end fixed to the limiting baffle on the corresponding side.

[0009] Preferably, the stone removal scraper is connected to the stone removal scraper connecting bracket by a pin shaft, and the two stone removal scraper connecting brackets are arranged one in front of the other. The stone removal scraper extends between the two stone removal scraper connecting brackets, and the pin shaft passes through the stone removal scraper connecting bracket and the stone removal scraper and is locked by a cotter pin.

[0010] The beneficial effects of this utility model are: Improved stone removal efficiency: It can efficiently remove stones of different sizes, shapes and positions. The multi-angle striking and prying method of the stone removal scraper enables the stone remover to cope with various complex situations. Compared with existing technologies, the stone removal is more thorough, greatly reducing the impact of stones on vehicle driving and improving the safety and stability of mining dump truck operation.

[0011] Protecting tires: Limiting springs are installed on both sides of the stone removal scraper, which effectively avoids damage to the tires during the stone removal process. It can buffer the impact force when the stone removal component collides with the stone, reduce scratches and bulges on the tire surface, thereby extending the tire's service life and reducing tire replacement costs.

[0012] The reasonable structural design and connection method ensure the reliability and stability of the destoner during long-term use, reduce downtime caused by failure, and improve the working efficiency of mining dump trucks. Attached Figure Description

Detailed Implementation

[0017] See Figure 1-3 This utility model relates to a desander for mining dump trucks, including a mounting base 1, a connecting beam 2, a desander scraper connecting bracket 3, a desander scraper 4, a limiting baffle 5, and a limiting spring 6. The mounting base 1 is fixed to the chassis frame (not shown in the figure) by bolts. One end of the connecting beam 2 is connected to the mounting base 1, and the other end is connected to the desander scraper connecting bracket 3. The desander scraper 4 is hinged to the center of the desander scraper connecting bracket 3, and the limiting baffles 5 are symmetrically installed on both sides. A limiting spring 6 is provided between the desander scraper 4 and the limiting baffle 5. The two limiting springs 6 are symmetrically arranged on the left and right sides. One end of the limiting spring 6 is fixed to the desander scraper 5, and the other end is fixed to the limiting baffle 5 on the corresponding side.

[0018] The stone removal scraper 4 is connected to the stone removal scraper connecting bracket 3 via a pin 7. The two stone removal scraper connecting brackets 3 are arranged one in front of the other. The stone removal scraper 4 extends between the two stone removal scraper connecting brackets 3. The pin 7 passes through the stone removal scraper connecting bracket 3 and the stone removal scraper 4 and is then locked by a cotter pin.

[0019] The mounting base 1 is a welded component, including a frame connecting plate 1.1, mounting ear plates 1.2, and a horizontal sealing plate 1.3. The frame connecting plate 1.1 is used to fix it to the chassis frame. Mounting bolts are evenly distributed around the perimeter of the frame connecting plate 1.1. The vertically arranged frame connecting plate 1.1 is connected to the horizontal sealing plate 1.3. The mounting ear plates 1.2 are connected to both the frame connecting plate 1.1 and the horizontal sealing plate 1.3, and the two mounting ear plates 1.2 are arranged on the left and right sides. One end of the connecting beam 2 is clamped between the two mounting ear plates 1.2 and connected by fastening bolts 8. The mounting ear plates 1.2 are provided with vertical grooves corresponding to the fastening bolts 8.

[0020] The height of the connecting beam 2 is adjustable. The bottom of the mounting base 1 is provided with a height adjustment mechanism, which includes an adjusting screw 9, an adjusting nut 10, and an adjusting top plate 11. The adjusting nut 10 is fixed on the horizontal sealing plate 1.3 of the mounting base 1. The adjusting screw 9 passes through the adjusting nut 10 and connects to the adjusting top plate 11. The adjusting top plate 11 abuts against the bottom of the connecting beam 2 on the side of the mounting base. The adjusting screw 9 drives the adjusting top plate 11 and one side of the connecting beam 2 on it to rise and fall, thereby realizing the height adjustment of the stone removal scraper 4 on the other side of the connecting beam 2.

[0021] Working principle: The height of the connecting beam 2 and the stone removal scraper 4 on it is adjusted by rotating the adjusting screw 9. The stone removal scraper 4 is rotatably set at the bottom of the connecting beam 2 by means of a pin 7, so that the stone removal scraper 4 can rotate freely around the pin 7 to adapt to stones at different positions and angles.

[0022] When the mining dump truck is in motion, the stone removal scraper 4 mounted on the chassis frame moves accordingly. During the movement, the stone removal scraper 4 contacts the limit spring 6, generating a reaction force to continuously strike and remove stones stuck between the tires. The limit spring 6 can effectively buffer the impact force generated when the stone removal assembly collides with the stones, reducing damage to the tires.

[0023] When encountering large stones or stones stuck deep in the tire treads, the stone-removing scraper automatically adjusts its angle according to the stone's position and shape. Through multi-angle striking and pushing, it removes the stone from between the tires or onto the road surface. The adjustment mechanism can adjust the height and angle of the stone-removing mechanism according to actual conditions, such as tire size, vehicle speed, and road conditions. For example, when driving on uneven roads, the height of the stone-removing scraper can be appropriately lowered using the height adjustment mechanism to bring it closer to the road surface and improve stone removal efficiency. When changing to different tire sizes, the angle of the stone-removing scraper can be adjusted using the adjustment mechanism to ensure that the stone-removing component can accurately strike and push away stones between the tires. The limit spring effectively buffers the impact force generated when the stone-removing scraper collides with a stone, reducing damage to the tire; it also protects the scraper itself and extends its service life.

[0024] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
