Description

Technical Field

[0001] This utility model relates to the technical field of coal screening industry, and more specifically, it relates to an anti-clogging vibrating coal screening machine. Background Technology

[0002] In the coal screening industry, screening equipment often needs to operate continuously under high-intensity working conditions. The screen plates are easily worn, deformed, or blocked due to long-term vibration and material friction. Traditional equipment usually adopts a fixed screen plate structure, and the screen plate replacement process is cumbersome and time-consuming. Due to the lack of convenient disassembly and installation mechanisms, operators usually need to stop the machine and use tools for complex disassembly, which not only increases equipment downtime but also prolongs the production cycle, resulting in low equipment maintenance efficiency. With the increase in screening demand and the frequent use of equipment, the impact of screen plate replacement on production is becoming increasingly significant. How to improve screen plate replacement efficiency has become an urgent problem to be solved in the industry.

[0003] In practical applications, due to the large differences in particle size, moisture content and impurity composition of coal materials, the screen plates of traditional screening equipment are prone to clogging. Clogging not only affects screening efficiency, but may also lead to equipment failure or even damage. Existing technology cannot effectively deal with the problem of screen plate clogging. Once clogging occurs, operators need to stop the machine for cleaning, and it is impossible to respond and handle it quickly during the production process, which affects the stability and efficiency of the overall production line. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides an anti-clogging vibrating coal screening machine to solve the above-mentioned technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging vibrating coal screening machine, comprising an installation frame, on which a screening mechanism is provided. The screening mechanism includes a connecting frame, a connecting piece, an installation shell, a hopper, a screen plate, and a vibrating motor. The connecting frame is installed on the installation frame, the connecting piece is installed on the top of the connecting frame, the installation shell is installed on the connecting piece, the hopper is installed inside the installation shell, the screen plate is installed on the hopper, the vibrating motor is installed on one side of the installation shell, and a quick-installation mechanism is provided on the screen plate. The quick-installation mechanism includes an insert rod, a fixed sleeve, a sliding groove, a slider, a locking rod, a locking groove, a push ring, and a sliding sleeve. The insert rod is installed on the hopper, the fixed sleeve is installed on the screen plate, the sliding groove is located on the inner wall of the fixed sleeve, the slider slides in the sliding groove, the locking rod is installed on the inner side of the slider, the locking groove is located on the outer wall of the insert rod, the push ring is located inside the fixed sleeve, and the sliding sleeve is installed on the outer wall of the push ring and slidably connected to the fixed sleeve.

[0006] The present invention is further provided that a spring is connected to the connecting member. The spring can effectively reduce the wear and tear on the device caused by vibration, extend the service life of the equipment, and improve the operational stability.

[0007] The present invention is further configured such that the slide groove is inclinedly disposed within the fixed sleeve, and the slider slides inclinedly within the slide groove. The cooperative design of the inclined slide groove and the slider enhances the flexibility of the quick-assembly mechanism, making disassembly and assembly more efficient and convenient.

[0008] The present invention is further configured such that a rotating sleeve is rotatably provided on the fixed sleeve, a support plate is provided on the rotating sleeve, and a baffle is provided at the bottom end of the support plate. The baffle abuts against the bottom surface of the sliding sleeve. By rotating the rotating sleeve, the movement position of the baffle can be easily controlled, thereby realizing the fixing or unlocking of the sliding sleeve and facilitating the quick assembly and disassembly of the screen plate.

[0009] The present invention is further configured such that the sliding sleeve is provided with a clearance groove, and multiple sets of clearance grooves are provided. The design of multiple sets of clearance grooves increases the flexibility of operation and makes the disassembly and assembly process more convenient and faster.

[0010] The present invention is further provided with a tension spring connecting the sliding sleeve and the fixed sleeve. Multiple sets of tension springs are provided. The arrangement of the tension springs can ensure that the sliding sleeve quickly returns to its original position after operation, thereby improving the automation level and work efficiency of the equipment operation.

[0011] The present invention is further configured such that an adjustment mechanism is provided on the mounting frame, the adjustment mechanism including a base frame, a limiting rail and a hydraulic cylinder, the base frame is rotatably mounted on the bottom end of the mounting frame, the limiting rail is mounted on both sides of the mounting frame and slidably connected to the base frame, and the hydraulic cylinder is rotatably mounted on the base frame and its output end is rotatably connected to the mounting frame.

[0012] The present invention is further configured such that a collecting hopper is installed on the base frame, which can effectively collect the screened material, reduce secondary pollution, and improve the efficiency and convenience of material processing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The screening mechanism is driven by a vibrating motor to vibrate the mounting shell. After the material enters the mounting shell, small coal particles pass through the screen holes on the screen plate into the collection area, while large coal particles are intercepted by the screen plate and discharged. This design significantly improves screening efficiency and effectively reduces the probability of material blockage. At the same time, the cooperation between the spring and the connecting frame in the screening mechanism plays a buffering role, which can effectively reduce the wear and tear on the device caused by vibration, extend the service life of the equipment, and improve the operational stability of the equipment.

[0015] 2. The quick-installation mechanism, through the cooperation of the insert rod, fixing sleeve, slider, and sliding groove, enables the rapid assembly and disassembly of the screen plate. When the screen plate needs to be replaced, rotating the rotating sleeve moves the support plate and baffle to the clearance groove position, thereby releasing the baffle from the sliding sleeve. Subsequently, the sliding sleeve drives the push ring to release the slider from the block, and the slider slides down the sliding groove, causing the locking rod to disengage from the slot, thereby releasing the locking of the insert rod. When a new screen plate needs to be installed, aligning the new screen plate with the fixed position and re-locking the locking rod and slot completes the fixing. This greatly shortens the maintenance and replacement time of the screen plate, reduces labor intensity, and improves the operating efficiency of the equipment.

[0016] 3. The adjustment mechanism, driven by a hydraulic cylinder, enables the angle adjustment of the screening device. The hydraulic system, through the sliding cooperation between the limit rail and the base frame, pushes the screening section to tilt, thereby controlling the movement speed and distribution of materials on the screen plate. When material blockage occurs, adjusting the angle of the screen plate allows the blockage to fall smoothly, effectively solving the problem of screen plate blockage and improving the stability and continuous operation capability of the equipment. A collection hopper is also installed on the base frame, which can conveniently collect and handle materials falling from the screen plate, further improving production efficiency and equipment reliability.

[0027] Please see Figures 1-6 A clog-resistant vibrating coal screening machine includes a mounting frame 1, on which a screening mechanism is mounted. The screening mechanism includes a connecting frame 2, a connecting piece 3, a mounting shell 4, a hopper 5, a screen plate 6, and a vibrating motor 7. The connecting frame 2 is mounted on the mounting frame 1, the connecting piece 3 is mounted on the top of the connecting frame 2, the mounting shell 4 is mounted on the connecting piece 3, the hopper 5 is mounted inside the mounting shell 4, the screen plate 6 is mounted on the hopper 5, the vibrating motor 7 is mounted on one side of the mounting shell 4, and a quick-installation mechanism is provided on the screen plate 6. The quick-installation mechanism includes an insert rod 8, a fixed sleeve 9, a sliding groove 10, a slider 11, a locking rod 12, a locking groove 13, a push ring 14, and a sliding sleeve 15. The insert rod 8 is installed on the discharge hopper 5, the fixed sleeve 9 is set on the screen plate 6, the sliding groove 10 is set on the inner wall of the fixed sleeve 9, the slider 11 slides in the sliding groove 10, the locking rod 12 is installed on the inner side of the slider 11, the locking groove 13 is set on the outer wall of the insert rod 8, the push ring 14 is set in the fixed sleeve 9, and the sliding sleeve 15 is installed on the outer wall of the push ring 14 and is slidably connected to the fixed sleeve 9.

[0028] A spring 16 is connected to the connector 3, which can buffer and absorb the vibration generated by the vibrating motor 7, reducing the direct impact on other components of the screening mechanism.

[0029] The slide groove 10 is inclinedly set inside the fixed sleeve 9, and the slider 11 slides inclinedly inside the slide groove 10. The slider 11 can slide along the inclined direction of the slide groove 10, making the movement of the slider 11 smoother. At the same time, the inclined design can use gravity to assist in achieving more precise disengagement or locking operations.

[0030] A rotating sleeve 17 is rotatably mounted on the fixed sleeve 9. A support plate 18 is mounted on the rotating sleeve 17. A baffle 19 is mounted at the bottom end of the support plate 18. The baffle 19 abuts against the bottom surface of the sliding sleeve 17. The rotating sleeve 17 rotates to drive the support plate 18 and the baffle 19 at its bottom end to move. When the baffle 19 abuts against the bottom surface of the sliding sleeve 17, the sliding sleeve is fixed. After the rotating sleeve 17 rotates, the baffle 19 leaves the bottom surface of the sliding sleeve, thereby releasing the constraint on the sliding sleeve.

[0031] The sliding sleeve 17 is provided with a clearance groove 20. Multiple clearance grooves 20 are provided. The clearance groove 20 serves as the opening structure of the sliding sleeve 17. When the baffle 19 is rotated to align with the clearance groove 20, the baffle 19 can be inserted into the clearance groove 20, thereby realizing the clearance function of the sliding sleeve 17 and providing space for the subsequent disassembly and assembly of components.

[0032] A tension spring 21 is provided between the sliding sleeve 17 and the fixed sleeve 9. Multiple sets of tension springs 21 are provided. The tension spring 21 provides a restoring force to the sliding sleeve 17 by connecting the sliding sleeve 17 and the fixed sleeve 9. When the sliding sleeve 17 is pulled or moved, the tension spring 21 will automatically reset the sliding sleeve 17 to the initial position.

[0033] In this embodiment, driven by the vibration motor 7, the mounting shell 4 vibrates. After the material enters the mounting shell 4, smaller coal particles fall into the collection area through the holes of the screen plate 6, while larger coal particles are intercepted and discharged by the screen plate 6. This method can significantly improve screening efficiency and reduce the probability of material blockage. The spring 16 and the connecting frame 2 act as a buffer, effectively reducing the wear and tear on the device caused by vibration. When the screen plate 6 needs to be replaced, rotating the rotating sleeve 17 drives multiple sets of support plates 18 to rotate, and the support plates 18 drive the baffle 19 to rotate and move to the clearance groove. Position 20 allows the baffle 19 to release its contact with the sliding sleeve 17. Subsequently, the sliding sleeve 17 drives the push ring 14 to release its contact with the slider 11. Then, the slider 11 slides down along the slide groove 10, causing the locking rod 12 to disengage from the slot 13, thereby releasing the locking of the insertion rod 8. When it is necessary to install the screen plate 6, the new screen plate 6 is aligned with the fixed position, and the locking rod 12 and the slot 13 are re-locked to complete the fixation. This quick disassembly and assembly design greatly shortens the maintenance and replacement time of the screen plate 6, reduces labor intensity, and improves the operating efficiency of the equipment.

[0034] Please see Figure 2 As one implementation of the adjustment mechanism: the mounting frame 1 is provided with an adjustment mechanism, which includes a base frame 22, a limit rail 23 and a hydraulic cylinder 24. The base frame 22 is rotatably mounted on the bottom end of the mounting frame 1, the limit rail 23 is mounted on both sides of the mounting frame 1 and is slidably connected to the base frame 22, and the hydraulic cylinder 24 is rotatably mounted on the base frame 22 and its output end is rotatably connected to the mounting frame 1.

[0035] A collection hopper 25 is installed on the base frame 22 to collect small coal particles or other materials screened off the screen plate 6, so as to facilitate unified processing or transportation.

[0036] More specifically, the angle adjustment of the screening device is achieved by hydraulic drive. The hydraulic system pushes the screening part to tilt through the sliding cooperation between the limit rail 23 and the base frame 22, thereby controlling the movement speed and distribution of the material on the screen plate 6. Then, the screen plate 6 can be operated to adjust the angle so that the blockage can fall smoothly when the material is blocked, and the blockage can be handled smoothly.

[0037] In use: Driven by the vibration motor 7, the mounting shell 4 vibrates. After the material enters the mounting shell 4, smaller coal particles fall into the collection area through the holes of the screen plate 6, while larger coal particles are intercepted and discharged by the screen plate 6. This method can significantly improve screening efficiency and reduce the probability of material blockage. The spring 16 and the connecting frame 2 act as a buffer, effectively reducing the wear and tear on the device caused by vibration. When the screen plate 6 needs to be replaced, rotating the rotating sleeve 17 drives multiple sets of support plates 18 to rotate, and the support plates 18 drive the baffle 19 to rotate and move to allow Positioning the slot 20 allows the baffle 19 to release its contact with the sliding sleeve 17. Subsequently, the sliding sleeve 17 drives the push ring 14 to release its contact with the slider 11. Then, the slider 11 slides down the slide groove 10, causing the locking rod 12 to disengage from the locking groove 13, thereby releasing the locking of the insertion rod 8. When it is necessary to install the screen plate 6, the new screen plate 6 is aligned with the fixed position, and the locking rod 12 and the locking groove 13 are re-locked to complete the fixation. This greatly shortens the maintenance and replacement time of the screen plate 6, reduces labor intensity, and improves the operating efficiency of the equipment.

[0038] The angle of the screening device is adjusted by hydraulic drive. The hydraulic system pushes the screening part to tilt through the sliding cooperation between the limit rail 23 and the base frame 22, thereby controlling the movement speed and distribution of the material on the screen plate 6. Then the screen plate 6 can be operated to adjust the angle so that the blockage can fall smoothly when the material is blocked, and the blockage can be handled smoothly.

For all the fixed connections mentioned above, welding is preferred.
