Description

Technical Field

[0001] This utility model relates to the field of tunneling machine shovel plates, and in particular to a coal mine tunneling machine shovel plate. Background Technology

[0002] In coal mining operations, tunneling machines are key equipment for achieving rapid tunnel excavation. Among them, the shovel plate, as an important component of the tunneling machine, is responsible for collecting and transferring materials.

[0003] During the material collection process, coal chunks, gangue, and other materials of various sizes enter the shovel plate indiscriminately. Oversized materials may cause blockages in subsequent transportation equipment, excessive wear on equipment such as crushers, and affect the service life of the equipment and coal mining efficiency. Therefore, in order to prevent larger materials from entering the shovel plate, this device is designed as a coal mine tunneling machine shovel plate. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a shovel plate for a coal mine tunneling machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shovel for a coal mine tunneling machine includes a shovel body, a star wheel mounted on the shovel body, a connecting frame mounted on the outer wall of the shovel body, and further includes:

[0007] A blocking mechanism, comprising a mounting frame, which is mounted on the shovel body via two support rods, and an adjustment groove is provided on the mounting frame, with multiple stop rods installed inside the adjustment groove;

[0008] An adjustment component is used to adjust the distance between two adjacent stop levers in order to limit excessive material from entering the shovel body;

[0009] The monitoring mechanism is used to monitor the position of the blocking mechanism. When an excessively large material is in front of the blocking mechanism, it triggers an alarm in the driver's cab.

[0010] The above technical solution further includes: the adjustment assembly includes a locking bolt and a nut; the mounting bracket has a fixing groove that communicates with the inside of the adjustment groove on the opposite side wall; the stop bar has a through hole on its outer wall; the locking bolt extends movably through the fixing groove and the through hole to the outside of the mounting bracket and is locked and fixed by the nut.

[0011] The inner wall of the adjustment groove is provided with a limiting groove, and a slider is fixedly installed on the outer wall of the stop rod. The slider is slidably connected to the inner wall of the limiting groove.

[0012] The monitoring mechanism includes a visual sensor, a controller, and a buzzer alarm, with the visual sensor and the buzzer alarm being electrically connected to the controller.

[0013] The vision sensor is mounted on the body of the tunneling machine, and the side of the blocking mechanism away from the star wheel is within the detection range of the vision sensor.

[0014] The buzzer alarm is installed in the driver's cab.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, a blocking mechanism is provided in front of the shovel star wheel. The blocking mechanism can block excessively large materials from entering the shovel, thereby reducing the occurrence of subsequent transportation blockages and improving the protection of the equipment.

[0017] 2. In this utility model, a monitoring mechanism is provided. The position of the blocking mechanism can be monitored through the monitoring mechanism. When there is an excessively large material in front of the blocking mechanism, the monitoring mechanism can alert the staff in the cab so that the staff can stop the machine in time to remove the excessively large material.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] See attached document Figure 1-5 The device includes a shovel body 10, a star wheel 11 mounted on the shovel body 10, and a connecting frame 12 mounted on the outer wall of the shovel body 10. The shovel body 10 still adopts the existing technology. This application does not improve the transmission mechanism of the shovel body 10 and the star wheel 11. The improvement of this device is to add a blocking mechanism on the basis of the original shovel body 10 to block excessively large materials.

[0028] Also includes:

[0029] The blocking mechanism includes a mounting frame 20, which is mounted on the shovel body 10 via two support rods 27. The mounting frame 20 has an adjustment groove 21, and multiple baffles 22 are installed inside the adjustment groove 21. By setting several baffles 22, a material channel is formed between two adjacent baffles 22. Materials smaller than the volume of the material channel can enter smoothly from the material channel, while materials larger than the volume of the material channel will be blocked outside the blocking mechanism.

[0030] An adjustment assembly is used to adjust the distance between two adjacent stop bars 22 to limit excessive material from entering the shovel body 10. The adjustment assembly includes a locking bolt 23 and a nut 24. The mounting frame 20 has fixing grooves 28 on opposite side walls that communicate with the interior of the adjustment groove 21. A through hole is formed on the outer wall of the stop bar 22. The locking bolt 23 extends through the fixing groove 28 and the through hole to the exterior of the mounting frame 20 and is locked in place by the nut 24. Here, the position of the stop bar 22 can be adjusted to regulate the size of the material channel inlet. When the position of the stop bar 22 needs to be adjusted, the nut 24 can be rotated counterclockwise, causing the outer wall of the nut 24 to move away from the outer wall of the mounting frame 20. This releases the fixation of the stop bar 22. Then, the stop bar 22 can be moved to adjust its position. After adjustment, the nut 24 is rotated clockwise until its end wall presses against the side wall of the mounting frame 20.

[0031] The inner wall of the adjusting groove 21 is provided with a limiting groove 25, and the outer wall of the stop rod 22 is fixedly installed with a slider 26, which is slidably connected to the inner wall of the limiting groove 25. In order to improve the stability of the movement of the stop rod 22, the limiting groove 25 and the slider 26 are provided. When the stop rod 22 moves, the slider 26 slides on the inner wall of the limiting groove 25.

[0032] The monitoring mechanism is used to monitor the position of the blocking mechanism. When an excessively large material is in front of the blocking mechanism, it triggers an alarm in the driver's cab. The monitoring mechanism includes a visual sensor, a controller, and a buzzer alarm. The visual sensor and the buzzer alarm are electrically connected to the controller.

[0033] The vision sensor is installed on the body of the tunneling machine, and the side of the blocking mechanism away from the star wheel 11 is within the detection range of the vision sensor.

[0034] The buzzer alarm is installed in the driver's cab.

[0035] In this embodiment, the working principle of the device is as follows: when transporting materials, the materials enter the shovel plate body 10 from the material channel on the blocking mechanism. When the materials pass through the material channel, materials with excessive volume can be blocked outside the shovel plate by the baffle 22, thereby preventing excessive materials from entering the shovel plate, reducing the phenomenon of subsequent transportation blockage, and improving the protection of the equipment.

[0036] In addition, the monitoring mechanism can monitor the position of the blocking mechanism. When a large volume of material is blocked outside the baffle 22, the visual sensor identifies the large volume of material and sends a signal to the controller. The controller then sends a signal to the buzzer alarm, which triggers the alarm and reminds the driver to stop the machine, so that the staff can handle the large volume of material in front of the blocking mechanism in a timely manner.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
