Technical Field

[0001] This utility model relates to the field of rock mining machines, specifically a rock mining machine saw blade adjustment device. Background Technology

[0002] A rock mining machine is a heavy-duty piece of machinery mainly used for rock mining operations at mining sites. It typically includes a main drilling and milling cutting mechanism, a lifting mechanism, an auxiliary cutter head, a feed mechanism, a power unit, and a speed transmission mechanism. Through different operating methods and functional characteristics, such as crushing, drilling, and blasting, rock mining machines can adapt to the mining needs of various rocks and are an indispensable and important piece of equipment in mining.

[0003] Please refer to the rock mining machine saw blade adjustment device with announcement number CN212508291 U.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1 to 4 The rock mining machine saw blade adjustment device in this embodiment includes two slide plates 1, two main gearboxes 2 and two saw blade bodies 16. The slide plates 1 are provided with connecting and fixing components and guide components.

[0025] Example 1: The connecting and fixing assembly includes four mounting bases 3 that are fixedly installed on the top of the two slide plates 1. Each of the two sets of mounting bases 3 has a hydraulic cylinder 4 fixedly installed on its top, and each of the two sets of hydraulic cylinders 4 has a connecting column 5 fixedly installed on its output end.

[0026] Two sliders 6 are slidably installed inside each of the two sets of connecting columns 5. Sliding grooves are opened inside each of the two sets of connecting columns 5. The sliders 6 are slidably connected to the connecting columns 5 through the sliding grooves, providing guidance for the movement of the positioning block 7, making the movement of the positioning block 7 more convenient.

[0027] Positioning blocks 7 are fixedly installed on the opposite sides of the two sets of sliders 6, and T-shaped push rods 8 are fixedly installed on one side of the two sets of sliders 6. Moving holes are opened on the outer side of the two sets of connecting columns 5. The T-shaped push rods 8 extend to the outer side of the connecting columns 5 through the moving holes. The user moves the sliders 6 up and down by moving the T-shaped push rods 8.

[0028] One side of each of the two sets of sliders 6 is threadedly connected to a fixing member 9. The fixing member 9 consists of a screw and a turntable. One end of the screw is fixedly installed with the turntable. A through hole is opened on the outer side of the connecting post 5. A threaded hole is opened on the front side of the slider 6. The fixing member 9 is threadedly connected to the slider 6 through the threaded hole and the through hole to fix and limit the slider 6 after sliding and adjustment. A snap-fit ​​block 10 is fixedly installed on the opposite side of each of the two sets of sliders 6.

[0029] It should be noted that the rock mining machine saw blade adjustment device is equipped with a connecting and fixing component, which facilitates the quick connection of the connecting column 5 at the output end of the hydraulic cylinder 4 to the main gearbox 2. When the main gearbox 2 needs to be disassembled for maintenance, the disassembly and installation process is simplified, and the efficiency of the device is improved.

[0030] Specifically, when disassembling the saw blade adjustment device of the rock mining machine, the two fixing parts 9 are rotated to release the threaded connection between the fixing parts 9 and the slider 6. Then, the fixing parts 9 are moved out of the slider 6. Subsequently, the two T-shaped push rods 8 are pushed in opposite directions to move, which simultaneously drives the slider 6 to move, moving the positioning block 7 out of the insertion slot in the mounting block 17. Then, the connecting column 5 is moved out of the mounting block 17, and the connecting column 5 is separated from the main gearbox 2. This facilitates the disassembly and maintenance of the main gearbox 2, thereby improving the quality of the device's use.

[0031] Example 2: Please refer to Figure 1 Based on Embodiment 1, a guide assembly is also provided on the slide plate 1. The guide assembly includes a mounting plate 11 fixedly installed on the opposite side of the two slide plates 1. A guide rod 12 is fixedly installed on the opposite side of the two mounting plates 11. Two slide tables 13 are slidably installed on the outer side of the guide rod 12.

[0032] The guide assembly also includes a first magnetic plate 14 fixedly installed on the top of both slides 13. The top of both slides 13 is provided with a mounting groove. The first magnetic plate 14 is fixedly connected to the slide 13 through the mounting groove. The bottom of both main gearboxes 2 is fixedly installed with a second magnetic plate 15. Two mounting blocks 17 are fixedly installed on the opposite side of both main gearboxes 2.

[0033] The top and bottom of the connecting column 5 are provided with extension holes, and the inside of the mounting block 17 is provided with a plug-in groove. The positioning block 7 is plugged into the mounting block 17 through the extension holes and the plug-in groove.

[0034] The mounting block 17 has a snap-fit ​​groove inside, and the snap-fit ​​block 10 snaps into the mounting block 17 through the snap-fit ​​groove. This is used to initially limit the connecting column 5 inside the mounting block 17 so that the hydraulic cylinder 4 can be installed and connected to the main gearbox 2. When the hydraulic cylinder 4 is started, the main gearbox 2 is moved, thereby achieving the purpose of adjusting the saw blade body 16.

[0035] It should be noted that the saw blade adjustment device of this rock mining machine, by installing a guide component, can provide guidance when the main gearbox 2 moves, making the movement of the main gearbox 2 more convenient, thereby improving the quality of saw blade adjustment.

[0036] Specifically, when the rock mining machine saw blade adjustment device needs to adjust the distance between the two saw blade bodies 16, it activates two sets of hydraulic cylinders 4, which drive the two main gearboxes 2 to move through the connecting column 5 and the mounting block 17. The magnetically attached slide table 13 at the bottom of the main gearbox 2 moves on the guide rod 12 to guide the movement of the main gearbox 2, making the movement of the main gearbox 2 more convenient, thereby achieving the purpose of adjusting the saw blade body 16.

[0037] The working principle of the above embodiments is as follows:

[0038] (1) When disassembling the saw blade adjustment device of the rock mining machine, rotate the two fixing parts 9 to release the threaded connection between the fixing parts 9 and the slider 6, then move the fixing parts 9 out of the slider 6, and then push the two T-shaped push rods 8 in opposite directions to move, which simultaneously drives the slider 6 to move, move the positioning block 7 out of the insertion slot in the mounting block 17, and then move the connecting column 5 out of the mounting block 17, and then disassemble the connecting column 5 from the main gearbox 2, so as to facilitate the disassembly and maintenance of the main gearbox 2, thereby improving the quality of the device.

[0039] (2) When the rock mining machine saw blade adjustment device needs to adjust the distance between the two saw blade bodies 16, the two sets of hydraulic cylinders 4 are started. Through the connecting column 5 and the mounting block 17, the two main gearboxes 2 are moved. The magnetic slide 13 at the bottom of the main gearbox 2 moves on the guide rod 12 to provide guidance for the movement of the main gearbox 2, making the movement of the main gearbox 2 more convenient, thereby achieving the purpose of adjusting the saw blade body 16.
