Description

Technical Field

[0001] This utility model relates to the field of coal mine conveyor technology, and in particular to a sectionally detachable chute structure for a coal mine conveyor. Background Technology

[0002] Coal mine conveyors are the main continuous transportation equipment for transporting coal in coal mines. They can work 24 hours a day without interruption, adapt to complex roadway layouts, and reduce labor costs. Common types include belt conveyors and scraper conveyors. The chute is the core trough-shaped component, welded from steel plates. It can be spliced ​​and some parts are equipped with wear-resistant liners. It is mainly used to carry the coal falling from the coal mining machine, guide the coal to flow in a designated direction, and isolate the coal from the conveyor transmission components to reduce wear. At the same time, it is an inseparable part of the overall system and the core component. Without the chute, the coal cannot be contained, and without the chute, long-distance continuous and efficient transportation cannot be achieved. Together, they constitute the core of the coal mine transportation system, ensuring the transportation of coal from the underground working face to the surface or designated locations.

[0003] However, when faced with wet or sticky materials, traditional fixed integrated chutes have high static friction between the material and the chute, which can easily cause material to accumulate and blockage, reducing conveying efficiency. At the same time, the fixed angle of traditional chutes cannot be flexibly adjusted according to equipment of different heights and the slope of the work site, resulting in poor adaptability.

[0004] Therefore, we provide a sectional, detachable chute structure for coal mine conveyors to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a baffle groove, a chute installed on the left side of the baffle groove, a vibration component installed on the lower surface of the chute, a top plate connected to the lower surface of the chute by bolts, a damping shock absorber fixedly connected to the lower surface of the top plate, a base bracket installed at the lower end of the damping shock absorber, an angle adjustment component fixedly connected to the lower end of the base bracket, a connecting rotating plate fixedly connected to the lower end of the base bracket, and a connecting bracket rotatably connected to the left end of the connecting rotating plate.

[0007] Preferably, a connecting groove is provided on the left side of the lower surface of the chute. The connecting groove is a T-shaped groove. An outlet groove is slidably connected to the left side of the chute through the groove. A connecting rod is installed on the right side of the lower surface of the outlet groove. A spring clip is fixedly connected to the lower surface of the right end of the connecting rod by a spring.

[0008] Preferably, the connecting groove corresponds to the connecting rod, and the spring snap block is snapped into the connecting groove, and the connecting rod and the spring snap block form an elastic connection.

[0009] Preferably, a vibration motor is fixedly connected to the center of the lower surface of the connecting plate by bolts, and four sets of damping shock absorbers are provided, and the top plate is connected to the base support through the damping shock absorbers.

[0011] Preferably, the surface of the threaded rod is provided with a movable base, the upper surface of the movable base is provided with a telescopic cylinder, and the telescopic end of the telescopic cylinder is hinged to the connecting rotating plate.

[0012] Preferably, the threaded rod and the motor are connected by a key, and the motor drives the movable base to move linearly by driving the threaded rod. The telescopic cylinder pushes the connecting plate to rotate under the action of the movable base.

[0013] This utility model provides a sectionally detachable chute structure for a coal mine conveyor. Compared with the prior art, it has the following advantages:

[0014] 1. This coal mine conveyor features a sectional, detachable chute structure. Vibration is generated by a vibrating motor and transmitted to the chute in stages, breaking the static friction between the coal material and the chute body, preventing accumulation and blockage, and improving conveying efficiency. It is especially suitable for wet or sticky materials. At the same time, four sets of damping shock absorbers can absorb the impact of vibration, reduce the transmission to other components, extend the service life of the device, and use bolted connections for stable installation. The vibration transmission path is clear, ensuring that the vibration acts efficiently on the chute without any unnecessary or ineffective vibration.

[0015] 2. This coal mine conveyor features a sectional, detachable chute structure. Through the cooperation of a motor and a telescopic cylinder, the chute can be driven to rotate around a pivot, allowing for free adjustment of the conveying angle. This adapts to equipment of different heights and work site slopes, solving the problem of poor adaptability of traditional chutes. The motor drives the threaded rod via a flat key, and combined with the precise action of the telescopic cylinder, it can smoothly push the chute to rotate, ensuring the accuracy and stability of the angle adjustment. In addition, the connecting plate provides a stable fulcrum, and the movable base can adjust the force application position, making the chute bear force evenly, avoiding local stress concentration, and protecting the chute structure.

[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] Please see Figure 1-4 This utility model provides a technical solution: a sectionally detachable chute structure for a coal mine conveyor, including a baffle trough 1, a chute 2 installed on the left side of the baffle trough 1, a vibration component 7 installed on the lower surface of the chute 2, a top plate 701 connected to the lower surface of the chute 2 by bolts, a damping shock absorber 702 fixedly connected to the lower side surface of the top plate 701, a base bracket 704 installed at the lower end of the damping shock absorber 702, an angle adjustment component 8 fixedly connected to the lower end of the base bracket 704, a connecting rotating plate 801 fixedly connected to the lower end of the base bracket 704, and a connecting bracket 802 rotatably connected to the left end of the connecting rotating plate 801.

[0023] A connecting slide 3 is provided on the left side of the lower surface of the chute 2. The connecting slide 3 is a T-shaped slide. A guide groove 4 is slidably connected to the left side of the chute 2 through the slide. A connecting slide rod 5 is installed on the right side of the lower surface of the guide groove 4. A spring clip block 6 is fixedly connected to the lower surface of the right end of the connecting slide rod 5 by a spring.

[0024] When assembling, pull down the spring clip 6, and then assemble along the connecting slide 3 using the connecting slide rod 5. When the connecting slide rod 5 reaches the top of the connecting slide 3, release the spring clip 6 so that the spring clip 6 is engaged inside the T-shaped slide of the connecting slide 3 for assembly. When disassembling, simply reverse the operation to achieve flexible assembly and disassembly of the two components.

[0025] The connecting slide 3 corresponds to the connecting slide rod 5, and the spring snap block 6 is snapped into the connecting slide 3. The connecting slide rod 5 and the spring snap block 6 form an elastic connection.

[0026] The connecting slide 5 and the spring locking block 6 are elastically connected by a spring. The spring force can push the spring locking block 6 into the connecting slide groove 3, thereby quickly fixing the relative position of the guide groove 4 and the chute 2. Applying force in the opposite direction can compress the spring, release the locking, and realize segmented disassembly.

[0027] A vibration motor 703 is fixedly connected to the center of the lower surface of the connecting plate 801 by bolts. There are four sets of damping shock absorbers 702, and the top plate 701 is connected to the base bracket 704 through the damping shock absorbers 702.

[0028] During use, the vibration motor 703 generates vibration, which is transmitted to the chute 2 through the connecting plate 801, base bracket 704, damping shock absorber 702, and top plate 701, causing the chute 2 to vibrate to assist in material conveying. The four sets of damping shock absorbers 702 can absorb the impact force generated by the vibration, reduce the impact of the vibration on the overall structure, and play a buffering and shock absorption role.

[0029] The connecting plate 801 is rotatably connected to the connecting bracket 802 via a rotating shaft. A threaded rod 803 is rotatably connected to the inner side of the connecting bracket 802, and a motor 804 is installed at the right end of the connecting bracket 802.

[0030] The rotatable connection between the connecting plate 801 and the connecting bracket 802 provides a fulcrum for the angle adjustment of the chute 2, while the cooperation between the threaded rod 803 and the motor 804 provides a power transmission path for subsequent driving angle adjustment.

[0031] The surface of the threaded rod 803 is provided with a movable base 805, and the upper surface of the movable base 805 is provided with a telescopic cylinder 806, and the telescopic end of the telescopic cylinder 806 is hinged to the connecting rotating plate 801.

[0032] The movable base 805 can move along its axial direction as the threaded rod 803 rotates, thereby driving the telescopic cylinder 806 above to move. The telescopic end of the telescopic cylinder 806 is connected to the connecting rotating plate 801 through a hinge. The telescopic action of the telescopic cylinder 806 can push the connecting rotating plate 801 to rotate around the rotating shaft, thereby adjusting the angle of the chute 2.

[0033] The threaded rod 803 and the motor 804 are connected by a key, and the motor 804 drives the moving base 805 to make linear motion by driving the threaded rod 803. The telescopic cylinder 806 pushes the connecting rotating plate 801 to rotate under the action of the moving base 805.

[0034] The motor 804 transmits power to the threaded rod 803 via a flat key, converting the rotational motion of the motor 804 into the rotational motion of the threaded rod 803. The threaded engagement between the threaded rod 803 and the movable base 805 further converts the rotational motion into the linear motion of the movable base 805. The telescopic cylinder 806 combines linear movement and telescopic action to apply a pushing or pulling force to the connecting rotating plate 801, causing it to rotate around the axis, ultimately achieving the adjustment of the conveying angle of the chute 2.

[0035] Working principle: When using this support device, first assemble the device, pull down the spring locking block 6 of the guide groove 4 to compress the spring between the connecting slide rod 5 and the locking block, align the connecting slide rod 5 of the guide groove 4 with the T-shaped connecting slide 3 of the chute 2 and push it into the top of the slide, then release the spring locking block 6, and use the spring force to lock it into the inside of the connecting slide 3, thus completing the fixed splicing of the chute 2 and the guide groove 4.

[0036] Subsequently, material conveying operations are carried out. The vibration motor 703 is started, and the vibration generated by it is transmitted to the chute 2 in sequence through the connecting plate 801, the base support 704, the damping shock absorber 702, and the top plate 701. The vibration of the chute 2 drives the coal and mineral materials to slide along the trough body to the outlet chute 4 and completes the conveying through the outlet chute 4. During this process, the four sets of damping shock absorbers 702 synchronously absorb the vibration impact to reduce the impact on the overall structure.

[0037] Next, when different conveying requirements need to be adapted, the motor 804 can be started, and the threaded rod 803 can be rotated through the flat key. This will cause the movable base 805 on the surface to move linearly along the axis of the threaded rod 803. The movable base 805 will drive the telescopic cylinder 806 above to move synchronously. The telescopic end of the telescopic cylinder 806 will push the connecting plate 801 to rotate around the axis of the connecting bracket 802 through the hinge, thereby adjusting the conveying angle of the chute 2.

[0038] Finally, when it is necessary to disassemble the device, pull down the spring locking block 6 to release its locking state with the connecting slide 3, and pull out the connecting slide rod 5 of the guide groove 4 in the opposite direction along the connecting slide 3, so as to realize the segmented disassembly of the chute 2 and the guide groove 4. In this way, the use of a segmented disassembly chute structure for a coal mine conveyor is completed.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
