Description

Technical Field

[0001] The utility model relates to the technical field of granite mining, in particular to a granite support-breaking mining device. Background Art

[0002] Granite is an igneous rock composed of mineral crystals, including feldspar, quartz, mica and other minerals. It is hard and wear-resistant, and has good compressive strength and weathering resistance. Open-pit mining is the most common mining method. The mined granite is widely used in construction, roads, sculptures, indoor and outdoor decoration, etc.

[0003] The existing utility model patent with application number CN201720554254.7 discloses a rock mining device. The utility model has a compact structure and good maneuverability when installed on carrying equipment such as excavators, and can be used for construction in complex terrains such as mountains. Compared with the existing technology, the heavy hammer of the utility model has a strong impact force when it falls at high speed; the breaker support, drill rod and crushing head assembly are wedge-shaped, gradually tapering from top to bottom, with high point pressure, easy to crush, and conducive to wedging and cracking hard objects such as stones. When the hammer body, breaker support, drill rod and crushing head are assembled into one, the inertia is large, which is conducive to crushing and reducing the impact of rebound. The crushing head can use standard picks equipped with cemented carbide, which has a long service life. After wear, only the crushing head needs to be replaced, which is low in cost.

[0004] The above-mentioned mining devices of the prior art have a chiseling head positioned at a single point of contact and lack a breaking function, which makes it difficult to control the direction of the granite cutting and separation. If a certain shape of granite is to be mined, the shape obtained by repeated chiseling at multiple points is not good, and it is impossible to control the shape of the granite chiseled to a certain extent. Utility Model Content

[0005] The purpose of the present utility model is to provide a granite breaking mining device to solve the problem that the mining device of the above-mentioned prior art proposed in the above-mentioned background technology is positioned as a single-point contact and lacks the breaking function, resulting in that the direction of the cutting and separation of the excavated granite is difficult to control. If a certain shape of granite is to be mined, the shape obtained by repeated excavation at multiple points is not good, and the shape of the excavated granite cannot be controlled to a certain extent.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] An embodiment provided by the present invention: Figure 1 As shown, a granite breaking mining device includes a fixed base 1, a shell 2, a first oil cylinder 3, a lifting frame 4 and a mining component 5.

[0025] like Figure 1 As shown, a fixing base 1 is disposed above the housing 2. The main body of the motor 11 is mounted inside the fixing base 1. The output end of the motor 11 is connected and fixed to the top of the housing 2. The fixing base 1 is mounted on the mobile device. When mining granite, the motor 11 drives the housing 2 to rotate. According to the actual situation of the on-site construction, the angle of the bottom end of the mining assembly 5 can be adjusted, thereby realizing the control of the direction of the mining of the granite.

[0026] like Figure 2 and Figure 3As shown, the mining assembly 5 is fixed below the lifting frame 4, and the lifting frame 4 is vertically slidably connected to the shell body 2 through the first oil cylinder 3. Limiting plates 41 are provided at the upper and lower ends of the lifting frame 4. A through groove is provided at the bottom of the shell body 2 and is sleeved on the side of the lifting frame 4. The limiting plate 41 at the upper end of the lifting frame 4 is located inside the shell body 2, and the body of the first oil cylinder 3 is fixed inside the shell body 2. The output end of the first oil cylinder 3 is fixedly connected to the limiting plate 41 at the upper end of the lifting frame 4. A track 31 is provided inside the shell body 2, and the limiting plate 41 at the upper end of the lifting frame 4 is provided with a roller 42, which is slidably connected to the track 31; the limiting plate 41 at the lower end of the lifting frame 4 is located outside the shell body 2; the outer diameter of the limiting plate 41 is larger than the inner diameter of the through groove provided at the bottom of the shell body 2, and the limiting plates 41 at the upper and lower ends of the lifting frame 4 are provided with gaskets 411 on the corresponding sides.

[0027] Driven by the first oil cylinder 3, the lifting frame 4 drives the mining assembly 5 below to move up and down cyclically relative to the shell 2, thereby achieving the excavation of granite at the corresponding position below the mining assembly 5. During the up and down movement of the lifting frame 4, the roller 42 of the upper limit plate 41 slides on the track 31, increasing the stability of each movement of the lifting frame 4 in the device, thereby improving the accuracy of the mining assembly 5 in excavating the granite. When the lifting frame 4 moves to the lowest position, the bottom surface of the upper limit plate 41 mates with the inner bottom side of the shell 2; when the lifting frame 4 moves to the highest position, the top surface of the lower limit plate 41 mates with the outer bottom side of the shell 2. During this mate, the provided gasket 411 can act as a buffer, reducing the impact of the lifting frame 4's up and down movement on the device and minimizing damage to the various components of the device.

[0028] like Figure 4 and Figure 5 As shown, the mining assembly 5 includes a counterweight 51, a slotting head 52, a propeller 53, and a second oil cylinder 54. The counterweight 51 is fixed to the bottom of the lifting frame 4. The counterweight 51 increases the force of gravity, increasing the impact of the slotting head 52 on the granite when it falls, thereby improving the excavation efficiency.

[0029] like Figure 6 As shown, the tip of the slotting head component 52 is vertically downward. The slotting head component 52 includes a connecting frame 521, a crushing seat 522, and a crushing head 523. The connecting frame 521 is fixedly connected to the bottom of the counterweight 51, and the crushing seat 522 is installed at the bottom of the connecting frame 521. The middle part of the expansion member 53 is rotatably connected to the edge of the connecting frame 521, and the crushing head 523 is installed at the bottom of the crushing seat 522. When the first cylinder 3 drives the lifting frame 4, the mining assembly 5 repeatedly impacts the granite at one location. The relatively hard crushing head 523 splits the granite surface. The outer shape of the combination of the crushing seat 522 and the expansion member 53 is small at the bottom and large at the top. This ensures that the crushing head 523 is sharp and can easily create a large gap in the granite, facilitating the expansion and separation of the granite in the next step.

[0030] Two sets of spreaders 53 are provided, symmetrically distributed about the slotted head 52, and pivotally connected to either side of the connecting bracket 521 of the slotted head 52. Two sets of second cylinders 54 are also provided, each connected to a corresponding spreader 53. The main body of the second cylinder 54 is hingedly connected to the counterweight 51 above the slotted head 52, and the output end of the second cylinder 54 is hingedly connected to the top of the spreader 53. When the second cylinder 54 is driven to extend, the upper end of the spreader 53 moves away from the counterweight 51, and the lower end of the spreader 53 abuts the side of the slotted head 52, where it fits into the groove between the crushing seat 522 and the inclined side of the crushing head 523. When the second cylinder 54 is driven to retract, the upper end of the spreader 53 moves closer to the counterweight 51, and the angle between the lower end of the spreader 53 and the side of the slotted head 52 increases. During the cyclic lifting process of the lifting frame 4, the second oil cylinder 54 is in an extended state, so that the inner side of the lower end of the support member 53 is in contact with the inclined side of the crushing seat 522, and the inclination of the outer side is an extension of the inclined surface of the crushing head 523, ensuring that the excavation effect will not be affected. After the crushing head 523 chisels a crack of a suitable size in the granite, the slotting head component 52 extends into the crack, and the second oil cylinder 54 drives the support member 53. The second oil cylinder 54 becomes shortened, and the angle between the lower ends of the support members 53 on both sides becomes larger, and the granite is spread and separated at the crack. Compared with the excavation at a single point position, this device can excavate the granite in the direction of the desired cutting and separation, and can control the shape of the granite excavation to a certain extent, thereby improving the commercial value of the mined granite.

[0031] The above are only embodiments of the present invention, and common knowledge such as the specific structures and characteristics of the scheme are not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
