Description

Technical Field

[0001] This invention relates to the field of coal conveyor technology, and more particularly to a coal conveyor for use in coal mines. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are usually dug underground to extract the coal. When the coal seam is very close to the surface, the surface soil is usually stripped directly to extract the coal. Most coal mines in my country are underground coal mines. During the mining process, the mined coal needs to be transported to a designated location.

[0003] Currently, existing coal conveyors, such as the patent with publication number CN112607452A, disclose a coal conveyor for coal mines, including a rail, a bottom box, and a carriage. The top of the bottom box is rotatably connected to the bottom of the carriage. The bottom of the bottom box is connected to support legs and wheels. The bottom box is rolledly connected to the rail via the wheels. The carriage contains a filter plate and a support block. The bottom of the filter plate overlaps with the top of the support block, and a connecting plate is welded to the right end of the filter plate. The carriage is threaded to the right side of the connecting plate. A protective ring is provided above the bottom box, and the top of the protective ring is welded to the bottom of the carriage. It uses a combination of an electric hydraulic rod and a pushing hole, which allows the electric hydraulic cylinder to lift the carriage through the pushing hole. During the lifting process, the carriage rotates with the rotating shaft, thereby realizing the self-unloading of coal in the carriage. The top of the electric hydraulic rod is protected by a collar to prevent direct contact with the bottom of the carriage and wear. However, the above device is prone to coal residue during unloading, making it inconvenient to use.

[0004] How to quickly and efficiently clear coal while avoiding coal residue, saving operation time, and improving transportation efficiency has become a technical problem that needs to be solved.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0006] In view of the above-mentioned defects, the purpose of this invention is to provide a coal conveyor for coal mines, which has a simple structure, is easy to use, can quickly and efficiently empty coal, avoid leaving coal residue, save operation time, and improve transportation efficiency.

[0007] To achieve the above objectives, the present invention provides a coal conveyor for a coal mine, including a base, a positioning component at the top of the base, the positioning component including symmetrically arranged positioning plates, and a sliding plate symmetrically arranged between the two positioning plates, the end of the sliding plate near the positioning plate being slidably connected to the positioning plate.

[0008] The base has a lifting platform inside, and the top of the lifting platform extends out of the base and into the mounting cavity. The lifting platform inside the mounting cavity has a holding box assembly. The holding box assembly includes symmetrically arranged support sleeves. Each support sleeve has a slidingly adjustable lifting rod inside. The top of each lifting rod extends out of the support sleeve. The top of each lifting rod is symmetrically hinged to a rotating frame. Each rotating frame is hinged to a rotating plate at the end away from the center of symmetry. A storage cavity is provided between the two rotating frames and the two rotating plates. A sealing cloth is provided between the two rotating frames.

[0009] During unloading, the two rotating frames rise and automatically rotate downwards due to gravity. The bottom of both rotating frames abuts the top of the sliding plate, and at the same time, the two rotating plates also automatically rotate downwards due to gravity, causing the coal in the storage chamber to slide out of the storage chamber.

[0010] According to the coal conveyor of the present invention, a fixed block is provided at the end of the sliding plate away from the center of symmetry.

[0011] According to the coal conveyor of the present invention, the lifting rod inside the support sleeve is symmetrically provided with inserts, and the support sleeve is provided with slots that cooperate with the inserts, and the inserts are slidably disposed in the slots.

[0012] According to the coal conveyor of the present invention, the bottom end of each lifting rod is connected to a telescopic member, and the bottom end of the telescopic member is connected to the inner wall of the support sleeve.

[0013] According to the present invention, the sealing cloth for a coal conveyor in a coal mine is a gusseted curtain.

[0014] According to the coal conveyor of the present invention, the bottom end of the base is provided with a plurality of wheels.

[0015] The purpose of this invention is to provide a coal conveyor for coal mines, including a holding box assembly. When the rotating frame and rotating plate of the holding box assembly rise, they automatically rotate downwards due to gravity, causing the coal in the storage chamber to slide out, accelerating the unloading speed, quickly and efficiently emptying the coal, avoiding coal residue, saving operation time, and improving transportation efficiency. A positioning assembly includes a sliding plate that can restrict the rotating frame and rotating plate during loading to prevent coal leakage, and provides a temporary support point for the rotating frame during unloading to facilitate unloading. In summary, the beneficial effects of this invention are: it can quickly and efficiently empty the coal, avoid leaving coal residue, save operation time, and improve transportation efficiency.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0023] See Figure 1 and Figure 2 The present invention provides a coal conveyor for a coal mine, including a base 1, a plurality of wheels 11 at the bottom end of the base 1 for easy movement, and a positioning component 2 at the top end of the base 1. The positioning component 2 includes symmetrically arranged positioning plates 21, and symmetrically arranged sliding plates 22 between the two positioning plates 21. The end of the sliding plate 22 near the positioning plate 21 is slidably connected to the positioning plate 21, thereby forming an installation cavity between the positioning plate 21 and the sliding plate 22.

[0024] See Figure 1 and Figure 2 Preferably, a fixing block 23 is provided at the end of the sliding plate 22 away from the center of symmetry, so that the user can pull the sliding plate 22.

[0025] See Figure 1 and Figure 2 Preferably, a motor capable of driving the wheels 11 can be installed in the base 1 and connected to a power source (setting a power drive device for the wheels 11 to facilitate movement is a conventional method for those skilled in the art, and its specific structure and connection method will not be described in detail here), saving manpower.

[0026] See Figure 1 and Figure 5 The base 1 has a lifting platform inside (not shown in the figure; the lifting electric drive device is a conventional structure in this field, and its specific structure and driving method are the same as those in the prior art, so it will not be described in detail here). The top of the lifting platform extends out of the base 1 and into the mounting cavity. The lifting platform inside the mounting cavity has a container assembly 3. The container assembly 3 includes symmetrically arranged support sleeves 31. The support sleeves 31 are hollow inside, and each support sleeve 31 has a sliding lifting rod 32 inside (each lifting rod 32 inside the support sleeve 31 has a symmetrically arranged insert block, and each support sleeve 31 has a slot that mates with the insert block, and the insert block is slidably arranged in the slot). Inside, the top of the lifting rod 32 extends through the support sleeve 31, and the bottom of the lifting rod 32 is connected to the telescopic member 33. The bottom of the telescopic member 33 is connected to the inner wall of the support sleeve 31. The telescopic member 33 can drive the lifting rod 32 to move up and down. The top of the lifting rod 32 is symmetrically hinged with a rotating frame 34. The end of the rotating frame 34 away from the center of symmetry is hinged with a rotating plate 341. The two rotating frames 34 and the two rotating plates 341 form a storage cavity for storing coal. A sealing cloth 35 is provided between the two rotating frames 34. The sealing cloth 35 is attached to the two rotating frames 34 to prevent coal from falling between the two rotating frames 34 during rotation.

[0027] See Figure 1 and Figure 5 Preferably, the telescopic component 33 is an electric cylinder that provides power to the telescopic component 33.

[0028] See Figure 1 and Figure 5 Preferably, the sealing cloth 35 is a gusseted curtain, which can prevent coal from falling between the two rotating frames 34 and has a certain deformation capacity so as not to hinder the movement of the rotating frames 34.

[0029] See Figure 1 and Figure 5 Loading process: When it is necessary to transport coal, the operator directly fills the coal into the storage cavity. The sliding plate 22 can restrict the rotating frame 34 and the rotating plate 341 to prevent coal from leaking out. After moving it to the target location, unloading can begin.

[0030] See Figure 1 and Figure 5 Unloading process: Activate the lifting platform to raise the holding box assembly 3. When the holding box assembly 3 moves above the positioning assembly 2, push the sliding plate 22 towards the side closer to the center of symmetry to avoid affecting unloading. Activate the telescopic component 33, which raises the two rotating frames 34. Since the two rotating frames 34 lose contact with the top of the support sleeve 31, they automatically rotate downwards due to gravity. The bottom of both rotating frames 34 abuts the top of the sliding plate 22. At this time, the two rotating frames 34 tilt, and the two rotating plates 341 also automatically rotate downwards due to gravity. The coal in the storage chamber slides out of the storage chamber. The tilted rotating frames 34 can speed up the unloading process and avoid leaving coal residue, saving operation time and improving transportation efficiency.

[0031] This invention provides a coal conveyor for coal mines, including a holding box assembly. When the rotating frame and rotating plate of the holding box assembly rise, they automatically rotate downwards due to gravity, causing the coal in the storage chamber to slide out, accelerating the unloading speed and enabling rapid and efficient emptying of coal while avoiding coal residue, saving operation time and improving transportation efficiency. A positioning assembly includes a sliding plate that can restrict the rotating frame and rotating plate during loading to prevent coal leakage, and provides a temporary support point for the rotating frame during unloading to facilitate unloading. In summary, the beneficial effects of this invention are: rapid and efficient emptying of coal while avoiding coal residue, saving operation time, and improving transportation efficiency.

[0032] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
