Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, and in particular to an anti-clogging screw conveyor for mining. Background Technology

[0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of conveying. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance and convenient closed transportation. During the conveying process, it can also agitate the materials. At present, screw conveyors are widely used in various industries, such as building materials, chemical, power, metallurgy, coal mining and grain, for horizontal or inclined conveying of powdery, granular and small block materials, such as coal, ash, slag, cement and grain.

[0003] However, in existing screw conveyors, materials tend to accumulate inside the feeding cylinder after prolonged use. This accumulation can lead to blockages over time, affecting the normal operation of the screw conveyor and making cleaning difficult. Therefore, this invention proposes an anti-blockage mining screw conveyor to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing screw conveyors, such as the tendency for materials to accumulate in the feeding cylinder after prolonged use. This accumulation can lead to blockages over time, affecting the normal operation of the screw conveyor and making cleaning difficult. Therefore, this invention proposes an anti-blockage screw conveyor for mining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clog-resistant screw conveyor for mining includes a housing, a drive motor, a screw rod, and a discharge port. The drive motor is fixedly mounted on the left side of a cover plate, and its output shaft extends to the inside of the housing. The screw rod is fixedly connected to the drive motor's output shaft, and the discharge port is fixedly mounted on the right side of the housing. The screw conveyor also includes...

[0007] The system includes a docking mechanism and a fixing mechanism, each in two sets, with the docking mechanism cooperating with the outer shell and the fixing mechanism, respectively.

[0008] The feeding mechanism includes: a cover plate and a feeding hopper;

[0009] The feed hopper is fixedly installed on the top of the cover plate, and the feed hopper is connected to the cover plate. The outer side of the cover plate is in sliding contact with the top of the outer shell.

[0010] As a preferred embodiment of the present invention, the docking mechanism includes: two fixed blocks, a sliding rod, two connecting rods, and a fixed rod;

[0011] Two fixed blocks are fixedly installed on the front and rear sides of the outer shell, respectively. The sliding rod is slidably connected to the top of the cover plate. The sliding rod slides in contact with the fixed blocks. The sliding rod is rotatably connected to the connecting rod. The connecting rod cooperates with the fixed rod. The fixed rod is fixedly installed on the top of the cover plate.

[0012] Furthermore, the connecting rod pulls the sliding rod to detach from the fixed block, significantly shortening the unblocking and maintenance time. The sliding contact structure buffers the vibration and impact of the equipment. After the sliding rod and the fixed block are in contact, the sliding rod can prevent the cover plate from detaching from the outer shell, thus enabling the installation of the cover plate. A sealing ring is installed on the outside of the cover plate to seal the outer shell.

[0013] As a preferred embodiment of this utility model, the fixing mechanism includes: a rotating frame, a positioning rod, and a fixing plate;

[0014] The rotating frame is rotatably connected to the front side of the connecting rod located at the front side, the positioning rod is rotatably connected to the inside of the rotating frame, and the fixing plate is fixedly installed on the top of the cover plate.

[0015] Furthermore, the downward rotating frame drives the positioning rod to engage with the groove in the fixed plate, forming a secondary mechanical lock to prevent the cover plate from shifting due to operational vibration, ensuring the stability of high-load conveying, and the unlocking operation is simple and quick.

[0016] In a preferred embodiment of this utility model, a circular block is fixedly installed on the connecting rod, and vertical grooves are provided on both the front and rear sides of the fixed rod, with the outer side of the circular block slidably connected to the inner wall of the vertical groove.

[0017] Furthermore, the circular block moves along the vertical groove to precisely transmit the unlocking force, preventing the mechanism from jamming.

[0018] In a preferred embodiment of this utility model, torsion springs are fixedly installed at the top and bottom of the positioning rod, and the torsion springs are fixedly connected to the rotating frame.

[0019] Furthermore, the torsion spring automatically resets the positioning rod to the locked position to prevent it from being forgotten to be fixed.

[0020] As a preferred embodiment of this utility model, the left side of the fixing plate is provided with a plurality of positioning grooves arranged at equal intervals, and the right end of the positioning rod slides in contact with the inner wall of the positioning groove.

[0021] Furthermore, the multi-level positioning grooves provide stable locking points to adapt to the sealing requirements of different working conditions.

[0022] As a preferred embodiment of this utility model, four vibration motors are fixedly installed on the front and rear sides of the outer shell, respectively.

[0023] Furthermore, the high-frequency vibration of the motor housing actively shakes off attached materials, preventing blockages from forming at the source.

[0024] Beneficial effects:

[0025] 1. The connecting rod pulls the sliding rod away from the fixed block, greatly shortening the cleaning and maintenance time. The sliding contact structure buffers the vibration and impact of the equipment. After the sliding rod is in contact with the fixed block, the sliding rod can prevent the cover plate from separating from the outer shell, thus enabling the installation of the cover plate. The outer side of the cover plate is equipped with a sealing ring, which can seal the outer shell.

[0026] 2. The downward rotating frame drives the positioning rod to engage with the groove of the fixed plate, forming a secondary mechanical lock to prevent the cover plate from shifting due to operational vibration, ensuring the stability of high-load conveying, and the unlocking operation is simple and quick;

[0027] In this utility model: the sliding contact design of the cover plate enables quick disassembly of the feed inlet, which facilitates thorough cleaning of accumulated materials and prevents blockage of the conveying channel. The connection structure between the feed hopper and the cover plate ensures smooth feeding and solves the problem of difficult unblocking in traditional equipment. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Example 1

[0035] Reference Figure 1-4 A clog-resistant screw conveyor for mining includes a housing 1, a drive motor 2, a screw rod 3, and a discharge port 4. The drive motor 2 is fixedly installed on the left side of a cover plate 5, and its output shaft extends to the inside of the housing 1. The screw rod 3 is fixedly connected to the output shaft of the drive motor 2. The discharge port 4 is fixedly installed on the right side of the housing 1. The screw conveyor also includes...

[0036] The system includes two sets of docking and fixing mechanisms, with the docking mechanism cooperating with the outer shell 1 and the fixing mechanism, respectively.

[0037] The feeding mechanism includes: cover plate 5 and feeding hopper 6;

[0038] The feed hopper 6 is fixedly installed on the top of the cover plate 5. The feed hopper 6 is connected to the cover plate 5, and the outer side of the cover plate 5 is in sliding contact with the top of the outer shell 1.

[0039] The above structure enables the quick disassembly of the feed inlet through the sliding contact design of the cover plate 5, which facilitates the thorough cleaning of accumulated materials and prevents blockage of the conveying channel. The connection structure between the feed hopper 6 and the cover plate 5 ensures smooth feeding and solves the problem of difficult unblocking in traditional equipment.

[0040] To secure the cover plate 5, the docking mechanism includes: two fixing blocks 8, a sliding rod 9, two connecting rods 10, and a fixing rod 11;

[0041] Two fixing blocks 8 are fixedly installed on the front and rear sides of the outer shell 1, respectively. The sliding rod 9 is slidably connected to the top of the cover plate 5. The sliding rod 9 is in sliding contact with the fixing block 8. The sliding rod 9 is rotatably connected to the connecting rod 10. The connecting rod 10 cooperates with the fixing rod 11. The fixing rod 11 is fixedly installed on the top of the cover plate 5. The connecting rod 10 pulls the sliding rod 9 away from the fixing block 8, which greatly shortens the cleaning and maintenance time. The sliding contact structure buffers the vibration and impact of the equipment. After the sliding rod 9 is in contact with the fixing block 8, the sliding rod 9 can prevent the cover plate 5 from separating from the outer shell 1, so that the cover plate 5 can be installed. A sealing ring is installed on the outside of the cover plate 5, so that the outer shell 1 can be sealed.

[0042] To achieve a seal on the outer casing 1, the fixing mechanism includes: a rotating frame 12, a positioning rod 13, and a fixing plate 15;

[0043] The rotating frame 12 is rotatably connected to the front side of the connecting rod 10 located at the front side, and the positioning rod 13 is rotatably connected to the inner side of the rotating frame 12. The fixing plate 15 is fixedly installed on the top of the cover plate 5. Pressing down the rotating frame 12 drives the positioning rod 13 to be inserted into the groove of the fixing plate 15, forming a secondary mechanical lock to prevent the cover plate 5 from shifting due to operational vibration, ensuring the stability of high-load conveying, and the unlocking operation is simple and quick.

[0044] In order to adjust the position of the sliding rod 9, a round block is fixedly installed on the connecting rod 10. Vertical grooves are opened on the front and rear sides of the fixed rod 11. The outer side of the round block is slidably connected to the inner wall of the vertical groove. The round block moves along the vertical groove to accurately transmit the unlocking force and avoid the mechanism from jamming.

[0045] In order to reset the positioning rod 13, torsion springs 14 are fixedly installed at the top and bottom of the positioning rod 13. The torsion springs 14 are fixedly connected to the rotating frame 12. The torsion springs 14 automatically reset the positioning rod 13 to the locked position to prevent forgetting to fix it.

[0046] In order to position the connecting rod 10, multiple positioning grooves are provided on the left side of the fixing plate 15 at equal intervals. The right end of the positioning rod 13 slides in contact with the inner wall of the positioning groove. The multi-level positioning grooves provide a stable locking point to adapt to the sealing requirements of different working conditions.

[0047] To prevent blockage, four symmetrically arranged vibration motors 7 are fixedly installed on the front and rear sides of the outer casing 1. The vibration motors 7 vibrate the outer casing 1 at high frequency to actively shake off the attached material and prevent blockage from the source.

[0048] The working principle of this utility model is as follows: The sliding contact design of the cover plate 5 enables quick disassembly of the feed inlet, facilitating thorough cleaning of accumulated materials and preventing blockage of the conveying channel. The connection structure between the feed hopper 6 and the cover plate 5 ensures smooth feeding, solving the problem of difficult unblocking in traditional equipment. Four symmetrically arranged vibration motors 7 are fixedly installed on the front and rear sides of the outer shell 1. The vibration motors 7 vibrate the outer shell 1 at high frequency, actively shaking off the attached materials and preventing blockage from the source. When it is necessary to disassemble the cover plate 5 and clean the outer shell 1, the positioning rod 13 needs to be rotated inside the rotating frame 12 first, so that the positioning rod 13 can be disengaged from the fixed plate 15, which can unlock the sliding rod 9. At this time, the connecting rod 10 pulls the sliding rod. Once rod 9 disengages from fixing block 8, cover plate 5 can be unlocked, opening housing 1 and significantly shortening cleaning and maintenance time. After cleaning, cover plate 5 is placed on top of housing 1, and connecting rod 10 is pressed down, causing it to slide on fixing rod 11. This pushes sliding rod 9 to engage with fixing block 8, squeezing cover plate 5 downwards to maintain the sealing reliability of housing 1, thus enabling cover plate 5 installation. A sealing ring is installed on the outside of cover plate 5 to seal housing 1. Then, positioning rod 13 is released, allowing it to automatically engage with fixing plate 15, forming a secondary mechanical lock to prevent cover plate 5 from shifting due to operational vibration, ensuring high-load conveying stability. The unlocking operation is simple and quick.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
