Description

Technical Field

[0001] This utility model relates to the field of stone transportation technology, specifically a stone mining and conveying device. Background Technology

[0002] In stone quarrying production lines, conveying devices are common equipment. They connect various production processes and meet the convenience needs of stone production.

[0003] Because the raw stone materials vary in size, the current conveying equipment has a single function and can only complete the conveying purpose. Specialized screening equipment is needed to screen the stone into different sizes before it can be further processed. Secondly, the feeding mechanism of the existing conveying equipment mostly adopts a straight or inclined feeding pipe. Due to gravity, the stone has a large impact force during the falling process, which causes great impact wear on the feeding mechanism and affects its service life. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a stone mining and conveying device that solves the problems of limited functionality and high impact during material feeding in existing stone conveying devices.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a stone mining and conveying device, including a feeding box, the top of which is provided with a feeding port, and a cage-type screening cylinder installed inside the feeding box, the top of which is provided with a feeding inlet.

[0008] A set of rotatable gates is provided on the left and right sides between the feed inlet and the feed outlet. The opening and closing angle of the gates is controlled by a cylinder on the back of the gate.

[0009] The cage-type screening cylinder is equipped with a rotatable spiral stirring shaft, which is driven by an external servo motor. A first discharge port is installed at the outlet of the cage-type screening cylinder, and a first belt conveyor is installed below the first discharge port.

[0013] (III) Beneficial Effects

[0014] This utility model provides a stone mining and conveying device. It has the following beneficial effects:

[0015] This stone mining and conveying device features a screening-equipped feeding mechanism. A cage-type screening cylinder performs initial screening of the stone, followed by secondary screening through screen holes at the bottom of the feeding box, thus completing the fine screening of the stone. After being conveyed by a belt conveyor, the stone can directly enter the deep processing stage. Furthermore, by incorporating a buffer component within the feeding mechanism, the impact of gravity on the stone is reduced, extending the service life of the feeder. Additionally, a gate with a controllable opening size is installed in the feeding channel to control the stone feeding speed and prevent accumulation. Attached Figure Description

[0021] 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.

[0022] like Figure 1-4As shown, this utility model provides a technical solution: a stone mining and conveying device, including a feeding box 1, the top of which is provided with a feeding port 3, and a cage-type screening cylinder 4 installed inside the feeding box 1. It should be noted that the cage-type screening cylinder 4 has a sealed structure near the feeding port 5 to prevent stones from being thrown into the feeding channel. In addition, the length of the cage-type screening cylinder 4 is not less than 30 meters to ensure the screening effect. The top of the cage-type screening cylinder 4 is provided with a feeding port 5.

[0023] The inside of the feeding box 1 is equipped with a triangular diversion platform 18, which is located between the feed inlet 3 and the gate 6. Multiple sets of springs 19 are installed on the diversion platform 18, and buffer feeding plates 2 are installed on the springs 19. The buffer feeding plates 2 not only have the purpose of buffering and absorbing energy, but also can achieve the purpose of diversion.

[0024] A set of rotatable gates 6 is provided on both the left and right sides between the feed inlet 3 and the feed outlet 5. The opening and closing angle of the gates 6 is controlled by cylinders 7 on their backs. The cylinders 7 can drive the gates 6 to deflect around their rotation axis at a certain angle, thereby controlling the size of the opening between the two gates 6, thus controlling the feeding speed and preventing material accumulation. For details on the connection between the cylinders 7 and the gates 6, please refer to the appendix. Figure 4 The connection between cylinder 7 and the inner wall of the feeding box 1 is also the same.

[0025] The cage-type screening cylinder 4 is equipped with a rotatable spiral stirring shaft 8, which is driven by an external servo motor 9. A first discharge port 10 is installed at the outlet of the cage-type screening cylinder 4, and a first belt conveyor 11 is installed below the first discharge port 10.

[0026] The bottom of the feeding box 1 is provided with a screen hole 12. The tilt angle of the screen hole 12 should be controlled within 15 degrees. The screen hole 12 is covered with a third discharge port 15. A belt conveyor can also be installed below the third discharge port 15 for conveying fine crushed stone. The bottom of the screen hole 12 is provided with a second discharge port 13. A second belt conveyor 14 is installed below the second discharge port 13.

[0027] A dust suction head 16 is installed on the front and back of the inner wall of the feeding box 1. The dust suction head 16 is distributed on the front and back sides of the cage screening cylinder 4. The dust suction head 16 is connected to an external vacuum cleaner 17. When the vacuum cleaner 17 is turned on, the dust inside the feeding box 1 can be absorbed through the dust suction head 16, reducing dust pollution.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] When in use, the stone enters the feeding box 1 through the feed inlet 3 and first flows through the buffer feeding plate 2. The back of the buffer feeding plate 2 is equipped with multiple sets of springs 19, which can be used to absorb the impact force of the stone due to gravity, thereby reducing the feeding speed of the stone and preventing the subsequent gate 6 and cage screening cylinder 4 from being subjected to strong impact.

[0030] Then the stone material enters the feed inlet 5 from the gate 6 and falls into the cage screening cylinder 4. The servo motor 9 is started to drive the spiral stirring shaft 8 to rotate, thereby stirring the stone material while conveying it towards the first discharge port 10.

[0031] Under the action of agitation, smaller stones pass through the cage-type screening cylinder 4, while larger stones fall through the first discharge port 10 onto the first belt conveyor 11 below and are transported out.

[0032] After the stone is thrown out from the outer wall of the cage screening cylinder 4, it will pass through the screen hole 12. During this process, the fine stone passes through the screen hole 12 and is discharged through the third discharge port 15, while the remaining stone falls through the second discharge port 13 and is output by the second belt conveyor 14.

[0033] In summary, this stone mining and conveying device, by setting up a feeding mechanism with screening function, can perform preliminary screening of stone through a cage-type screening cylinder. Furthermore, it can perform secondary screening of the material through screen holes opened at the bottom of the feeding box, thereby completing the fine screening of stone. After being conveyed by the belt conveyor, the stone can directly enter the deep processing stage. Furthermore, by setting up a buffer component in the feeding mechanism, the impact of gravity on the stone can be reduced, and the service life of the feeder can be improved. At the same time, a gate with controllable opening size is also set in the feeding channel to control the feeding speed of stone and avoid accumulation.
