Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically to a mining quarrying equipment. Background Technology

[0002] In mining operations, it is often necessary to further cut and separate the mined sections to gradually chisel away the ore. This typically involves marking planned cracks within a predetermined area, then inserting appropriate chisel tools into the cracks to separate the ore. For large mined ore blocks, due to their massive size, further chiseling is also required. Similarly, a crack must first be chiseled into the ore surface, followed by the insertion of wedges and other tools to separate it. Currently, these operations are mostly performed using traditional methods: manually cutting a predetermined crack of a certain depth, then chiseling along the crack. However, because the pre-cut crack always has limitations in depth, the ore may not crack along the intended path, necessitating further pre-cutting and separation, which is very cumbersome. Summary of the Invention

[0003] The purpose of this utility model is to provide a mining quarrying equipment that solves the problem in the prior art that the pre-drilled cracks cannot effectively guide the ore to split before it is completely separated.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A quarrying equipment includes a main frame 1, within which a cutting disc 2, a cutting saw 6, and a drive mechanism for driving the cutting disc 2 to rotate are installed.

[0006] The driving mechanism includes a drive motor 7, which is horizontally installed in the main frame 1 in the left-right direction. A cutting disc 2 and a drive wheel 3 are fixedly installed on the output shaft 8 of the drive motor 7. A rotating shaft 501 is rotatably installed in the main frame 1 behind the cutting disc 2 through a bracket 17. A driven wheel 9 and a gear 502 are installed on the rotating shaft 501. The driven wheel 9 is linked to the drive wheel 3 through a transmission belt 4. The cutting saw 6 is fixedly installed on a rack 503, and the rack 503 meshes with the gear 502 for transmission.

[0007] A rectangular notch 101 is vertically opened on the inner main frame 1 of the bracket 17. The cutting saw 6 is vertically arranged in the rectangular notch 101. Slide grooves are vertically arranged on the left and right sides of the rectangular notch 101. Slide blocks 16 are arranged on the left and right sides of the cutting saw 6. The slide blocks 16 are movably arranged in the slide grooves.

[0008] The cutting saw 6 is equipped with a ramp 14, and a pressure spring 15 is vertically arranged between the ramp 14 and the main frame 1.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0010] This utility model has a simple structure and is easy to manufacture, install and use. By setting up a linkage cutting disc and cutting saw, it can automatically perform pre-grooving operations on a predetermined mining area or large ore after blasting, creating special grooves to guide the ore to continue to break and separate along a predetermined path, thereby improving the efficiency of mining.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0021] like Figure 1-4 This embodiment provides a quarrying equipment, including a main frame 1. The main frame 1 has a rectangular opening with openings at the top and bottom. A cutting disc 2, a cutting saw 6, and a drive mechanism for driving the cutting disc 2 to rotate are installed in the opening of the main frame 1.

[0022] The driving mechanism includes a drive motor 7, which is horizontally mounted within the main frame 1 in a left-right direction. A cutting disc 2 and a drive wheel 3 are fixedly mounted on the output shaft 8 of the drive motor 7. The free end of the output shaft 8 is rotatably mounted on the main frame 1 via a bearing. A rotating shaft 501 is rotatably mounted within the main frame 1 behind the cutting disc 2 via a bracket 17. A driven wheel 9 and a gear 502 are fixedly mounted on the rotating shaft 501. The driven wheel 9 is linked to the drive wheel 3 via a transmission belt 4. That is, the drive wheel 3 drives the driven wheel 9, the rotating shaft 501, and the gear 502 to rotate together via the transmission belt 4. A rack 503 is vertically arranged, and a cutting saw 6 is fixedly mounted on the rack 503. The rack 503 and the gear 502 intermittently mesh, and the rotating gear 502 drives the rack 503 and the cutting saw 6 on it to move linearly. The diameter of the drive wheel 3 is larger than the diameter of the driven wheel 9, so that the cutting saw 6 cuts more frequently.

[0023] A rectangular notch 101 is vertically opened on the rear side of the inner main frame 1 of the bracket 17. The cutting saw 6 is vertically arranged in the rectangular notch 101. Slide grooves are vertically arranged on the left and right sides of the rectangular notch 101. Slide blocks 16 are fixedly arranged on the left and right sides of the cutting saw 6. The slide blocks 16 are movably arranged in the slide grooves. The slide blocks 16 cooperate with the slide grooves to guide the cutting saw 6 to move vertically in a straight line only along the direction of the slide grooves, preventing it from falling off.

[0024] A ramp 14 is provided on the cutting saw 6 or the rack 503, and a pressure spring 15 is vertically arranged between the ramp 14 and the main frame 1. Specifically, a rectangular groove is also provided on the rear side of the rectangular notch 101, the ramp 14 extends horizontally into the rectangular groove, and the pressure spring 15 is located within the rectangular groove. One end of the pressure spring 15 is set on the ramp 14, and the other end is set on the main frame 1 at the top of the rectangular groove. When the gear 502 and the rack 503 are in a meshing state, the pressure spring 15 is under pressure. When the gear 502 and the rack 503 move to a non-meshing state, the rack 503 moves vertically upward to its original position due to the elastic restoring action of the pressure spring 15, at which point it does not cut the ore.

[0025] The cutting disc and cutting saw of this invention are linked by a linkage mechanism (driving wheel, driven wheel, and transmission belt, etc.). This linkage mechanism allows the rotating cutting disc to move across the ore to be mined while the cutting saw intermittently cuts a series of oblique grooves along the grooves created by the cutting disc. These blind holes have a specific depth, facilitating better cracking of the ore along the grooves. This process is automated, convenient, and saves time and effort. Specifically, this linkage mechanism is mounted on a movable main frame. This main frame 1 can be existing movable equipment or custom-made by those skilled in the art, such as a trolley or a drive arm fixedly connected to an engineering vehicle. The drive arm moves, carrying the main frame with it. If necessary, it can also be handheld, allowing the user to hold the main frame and move it along the desired path to cut the required cracks. Alternatively, a dedicated track can be provided for the main frame to move, enabling the cutting disc and cutting saw to cut.

[0026] In more detail, such as Figure 2-3 The output shaft 8 of the drive motor 7 is connected to the cutting disc 2 and the drive wheel 3. The drive wheel 3 is connected to the driven wheel 9 via the drive belt 4. The driven wheel 9 is connected to the gear and rack pair 5 (drive gear 502; driven rack 503) so that the cutting saw 6 connected to the gear and rack pair 5 moves vertically. When moving vertically downwards, it gradually cuts out shapes such as... Figure 5 The diagram shows a series of evenly spaced, inclined grooves deeper than the cracks, designed to assist in the subsequent excavation and splitting of the ore. Example

[0027] The difference between this embodiment and Embodiment 1 is that, as Figure 6In order to achieve speed-up transmission, a cylinder 11 is coaxially mounted on the output shaft 8 of the drive motor 7 via a bearing. At the same time, a boss is provided on the rear end of the cylinder 11, and a cover plate is fixed on the front end cover of the drive motor 7. A groove is provided on the outer side of the cover plate to engage with the boss of the cylinder 11, so as to prevent the cylinder 11 from moving along the output shaft 8 while rotating. The drive wheel 3 is fixedly mounted on the cylinder 11, and the first gear 10 is also fixedly mounted on the cylinder 11. The end of the output shaft 8 extends out of the cylinder 11. The cutting disc 2 is fixedly mounted on the output shaft 8. An internal gear ring 12 is coaxially fixedly mounted on the end face of the cutting disc 2 facing the first gear 10. The first gear 10 is located in the center of the internal gear ring 12. A second gear 13 is rotatably mounted between the internal gear ring 12 and the first gear 10. The second gear 13 is rotatably mounted on a rotating shaft fixed on a cover plate that is integrally fixed with the drive motor 7, so as to achieve speed-increasing transmission connection with the first gear 10. This allows the cutting saw 6 to further deepen the cut almost along the entire groove cut by the cutting disc 2, avoiding the impact on cutting performance due to excessive depth in one cut, and achieving sequential cutting. If the cutting saw 6 only needs to cut once at a long interval, the design can be reversed, that is, the internal gear ring 12 is mounted on the cylinder 11, and the first gear 10 is fixed on the output shaft 8 to achieve speed reduction transmission, avoiding excessively frequent vertical reciprocating movement of the cutting saw 6 when the cutting disc 2 rotates at high speed.
