Description

Technical Field

[0001] This utility model relates to the field of coal roadway excavation, specifically a fast coal roadway excavation machine. Background Technology

[0002] With the development of the times, more and more minerals are being mined and more and more mining areas are being explored. The mine shaft and tunnel mining method is favored because of its small environmental impact.

[0003] Existing mine roadways are generally excavated using tunneling machines. The front end of the tunneling machine digs out the soil and moves it to the rear end, thus completing the excavation of the coal roadway. However, existing coal roadway tunneling machines have shortcomings. Most of them are too large and excavate circular coal roadways, which is not conducive to the transportation of personnel and minerals. Smaller tunneling machines, on the other hand, have low speed and poor stability.

[0004] In view of this, in order to overcome the above-mentioned technical problems, this utility model designs a fast coal roadway tunneling machine, which solves the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides the following technical solution:

[0006] This utility model provides a fast coal roadway tunneling machine, comprising: a frame and tunneling rollers.

[0007] The chassis is equipped with a tunneling roller for digging soil, and a conveyor belt is installed below the chassis. The conveyor belt is driven by a built-in motor and is used to transport the excavated soil to the rear.

[0008] The excavating roller is mounted on the front end of the articulated rod, and a main motor is mounted on the articulated rod. The main motor is connected to the excavating roller via a pulley and a belt. The main motor is used to drive the excavating roller to rotate. The rear end of the articulated rod is hinged to the vehicle frame, the middle part of the articulated rod is hinged to the lower end of the hydraulic cylinder, and the upper end of the hydraulic cylinder is hinged to the vehicle frame.

[0009] The main motor drives the excavation roller to rotate via pulleys and belts. The excavation roller can dig out the soil in front of the tunneling machine. At the same time, the electric actuator drives the hinge rod to swing, which causes the excavation roller to swing up and down to dig out the soil in front of the tunneling machine. The excavated soil falls onto the conveyor belt and is transported to the rear of the tunneling machine. Then, the operators transport the excavated soil away from the rear, thus completing the tunneling work of the coal roadway.

[0010] Preferably, tracks are mounted on both sides of the chassis, and the tracks are driven by motors to propel the tunneling machine forward. The tracks have significant propulsive force, making them highly suitable for working environments such as coal mine tunneling.

[0011] Preferably, a support belt is provided at the top of the vehicle frame. The support belt is driven by an electric motor and is used to support the top of the coal roadway. By providing support for the top of the mine roadway, it is possible to prevent the coal roadway from collapsing and burying the tunneling machine if no support is provided.

[0012] Preferably, the tunneling roller rotates counterclockwise, and a plurality of buckets are provided on the tunneling roller, with the bucket openings facing upwards. The purpose of rotating the tunneling roller counterclockwise and making the bucket openings face upwards is to move the soil excavated by the tunneling roller upwards and throw it onto the conveyor belt, thus preventing the excavated soil from blocking the forward direction of the tunneling machine.

[0013] Preferably, the front end of the conveyor belt extends beyond the chassis. This design allows the soil excavated by the tunneling rollers to fall more effectively onto the conveyor belt and be transported to the rear of the tunneling machine.

[0014] Preferably, the distance between the two ends of the tunneling roller is greater than the distance between the edges of the two tracks. This design aims to allow the tracks to advance more effectively and prevent them from getting stuck in excessively narrow coal roadways.

[0015] Beneficial effects: The digging roller can excavate the soil in front of the tunneling machine, and the electric actuator drives the hinged rod to swing, causing the digging roller to swing up and down to dig the soil in front of the tunneling machine. The excavated soil falls onto the conveyor belt and is transported to the rear of the tunneling machine, where the operators then transport the excavated soil away. The tracks propel the tunneling machine forward, and the support belts support the top of the mine roadway, thus completing the tunneling work. Attached Figure Description

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to the accompanying drawings and embodiments. To address the problem that existing coal roadway tunneling machines are too large and produce mostly circular holes, the following solution is proposed:

[0024] Preferably, a fast coal roadway tunneling machine includes a frame 1 and a tunneling roller 2;

[0025] The frame 1 is equipped with a tunneling roller 2, which is used to excavate soil. A conveyor belt 12 is installed below the frame 1. The conveyor belt 12 is driven by a built-in motor and is used to transport the excavated soil to the rear.

[0026] The tunneling roller 2 is mounted on the front end of the hinge rod 22. A main motor is mounted on the hinge rod 22. The main motor is connected to the tunneling roller 2 via a pulley and a belt. The main motor is used to drive the tunneling roller 2 to rotate. The rear end of the hinge rod 22 is hinged to the frame 1. The middle part of the hinge rod 22 is hinged to the lower end of the hydraulic cylinder 23. The upper end of the hydraulic cylinder 23 is hinged to the frame 1.

[0027] The main motor drives the tunneling roller 2 to rotate via pulleys and belts. The tunneling roller 2 can excavate the soil in front of the tunneling machine. At the same time, the electric push rod drives the hinge rod 22 to swing, thereby causing the tunneling roller 2 to swing up and down to excavate the soil in front of the tunneling machine. The excavated soil will fall onto the conveyor belt 12 and be transported to the rear of the tunneling machine. Then, the operators will transport the excavated soil away from the rear, thus completing the tunneling work of the coal roadway.

[0028] Preferably, tracks 11 are mounted on both sides of the chassis 1. The tracks 11 are driven by motors and are used to drive the tunneling machine forward. The tracks 11 have a large propulsive force, making them very suitable for working environments such as coal mine tunneling.

[0029] Preferably, a support belt 13 is provided at the top of the frame 1. The support belt 13 is driven by an electric motor and is used to support the top of the coal roadway. By providing the support belt 13 to support the top of the mine roadway, it is possible to prevent the coal roadway from collapsing and burying the tunneling machine if no support is provided.

[0030] Preferably, the tunneling roller 2 rotates counterclockwise, and a plurality of buckets 21 are provided on the tunneling roller 2, with the shovel openings of the buckets 21 facing upwards. The purpose of rotating the tunneling roller 2 counterclockwise and making the shovel openings of the buckets 21 face upwards is to move the soil excavated by the tunneling roller 2 upwards and throw it onto the conveyor belt 12, thus preventing the excavated soil from blocking the forward direction of the tunneling machine.

[0031] Preferably, the front end of the conveyor belt 12 extends beyond the frame 1. This design allows the soil excavated by the tunneling roller 2 to fall more effectively onto the conveyor belt 12 and be transported to the rear of the tunneling machine.

[0032] Preferably, the distance between the two ends of the tunneling roller 2 is greater than the distance between the edges of the two side tracks 11. The purpose of this design is to allow the tracks 11 to move forward more smoothly and to prevent the tracks 11 from getting stuck in a narrow coal roadway.

[0033] Working process: The excavating roller 2 digs out the soil in front of the tunneling machine. Simultaneously, the electric actuator drives the hinged rod 22 to swing, causing the excavating roller 2 to swing up and down, thus excavating the soil in front of the tunneling machine. The excavated soil falls onto the conveyor belt 12 and is transported to the rear of the tunneling machine, where operators then remove it. The track 11 propels the tunneling machine forward, and the support belt 13 supports the top of the mine roadway. This completes the tunneling work in the coal roadway. This design makes this tunneling machine highly suitable for excavating narrow, square coal roadways, and it is efficient and stable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
