Description

Technical Field

[0001] This utility model relates to the field of conveyor head chute, and in particular to a guide plate for a conveyor head chute of a tape conveyor. Background Technology

[0002] Belt conveyors are used for transporting coal in coal mines. A motor drives a belt to rotate, thus achieving the purpose of coal transportation. In the production system of a coal preparation plant, the material distribution device at the head chute of the belt conveyor is a core component that ensures accurate material distribution and efficient conveying.

[0003] Traditional material distribution devices often employ a gate structure, distributing materials through manual or mechanical adjustment of the gate's opening and closing. However, this type of gate has significant shortcomings in practical applications. First, the gate is inconvenient to adjust, making it difficult to achieve proper material distribution and easily leading to uneven material distribution, affecting the efficiency of subsequent processes. Second, material distribution via a gate is prone to blockages during transport, requiring frequent cleaning of the machine head chute by on-site personnel. This not only increases minor delays but also significantly increases the labor intensity of workers. Furthermore, the increased workload due to frequent shutdowns and adjustments severely impacts production continuity and economic efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a guide plate for the head chute of a tape conveyor to solve the problems mentioned in the background art.

[0013] A telescopic snap-fit ​​mechanism is installed inside the through shaft and is movably snapped into the guide baffle.

[0014] An unlocking mechanism is installed at the end of the through shaft and is used to unlock the telescopic snap-fit ​​mechanism.

[0015] Preferably, the telescopic snap-fit ​​mechanism includes:

[0016] A sliding block, wherein multiple sliding blocks are arranged in pairs opposite to each other, the sliding blocks are slidably inserted into the through shaft, and the sliding blocks are perpendicular to the axis of the through shaft;

[0017] An elastic support assembly is connected between opposing sliding blocks.

[0018] Preferably, the elastic support component includes:

[0019] Telescopic rods, which are connected between opposing sliding blocks, and multiple telescopic rods are staggered relative to each other;

[0020] A spring, which is movably sleeved on the outside of the telescopic rod.

[0021] Preferably, the unlocking mechanism includes:

[0022] A rotating shaft, which is coaxially arranged with the through shaft;

[0023] A turntable is connected to one end of a rotating shaft. The turntable has multiple guide grooves, and the multiple guide grooves are arranged in an inclined circular array relative to the center of the turntable.

Detailed Implementation

[0038] 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.

[0039] This utility model provides, for example Figure 1-7 The illustrated conveyor belt machine head chute guide plate includes: a main chute 1, which is a vertically continuous tubular structure. The width of the main chute 1 is greater than that of conventional technology, allowing it to hold more material; a branch chute 2, which is connected to the discharge end of the main chute 1 and has two downward-sloping discharge ports. The main chute 1 and branch chute 2 together form an inverted Y-shape, allowing the falling direction of the material falling from the main chute 1 to be selected from the two discharge ports of the branch chute 2; a guide baffle 3, which is rotatably disposed inside the branch chute 2 to guide the material falling from the main chute 1; a handle 4, which is rotatably disposed on the front of the branch chute 2; and a detachable snap-fit ​​device 5. One end of the detachable snap-fit ​​device 5 is connected to the handle 4, and the other end of the detachable snap-fit ​​device 5 is snapped to the guide baffle 3. The rotation of the guide baffle 3 replaces the traditional material distribution gate. The guide baffle 3 is connected to the handle 4 through the detachable snap-fit ​​device 5, so that the rotation angle of the guide baffle 3 can be controlled by the handle 4. Since the guide baffle 3 and the handle 4 are set in parallel, the angle position of the guide baffle 3 in the main chute 1 can also be clearly determined by observing the angle of the handle 4, ensuring uniform material distribution, improving overall production efficiency, reducing the probability of material blockage, greatly reducing the operation frequency and labor intensity of on-site personnel, and reducing the sporadic delay time caused by downtime for adjustment. This improvement not only enhances the reliability of the guide baffle 3, but also provides strong support for efficient and continuous production in coal preparation plants. By unlocking the connection between the detachable snap-fit ​​device 5 and the guide baffle 3, the detachable snap-fit ​​device 5 can be removed from the insertion between it and the guide baffle 3. At this time, the detachable snap-fit ​​device 5 no longer positions the guide baffle 3, and the guide baffle 3 can be replaced.

[0040] Example 1

[0041] The detachable snap-fit ​​device 5 includes: an insert shaft 51, the end of which is fixedly inserted into one end of the handle 4, and the insert shaft 51 is slidably inserted into the guide baffle 3; a telescopic snap-fit ​​mechanism 52, which is installed inside the insert shaft 51 and is movably snap-fitted into the guide baffle 3; and an unlocking mechanism 53, which is installed at the end of the insert shaft 51 and is used to unlock the snap-fit ​​of the telescopic snap-fit ​​mechanism 52.

[0042] The telescopic locking mechanism 52 includes: sliding blocks 521, multiple sliding blocks 521 are arranged in pairs opposite each other, the sliding blocks 521 are slidably inserted into the through shaft 51, and the sliding blocks 521 are perpendicular to the axis of the through shaft 51; and an elastic support assembly, the elastic support assembly is connected between the opposite sliding blocks 521. The elastic support assembly includes: a telescopic rod 522, which is connected between opposing sliding blocks 521, and the multiple telescopic rods 522 are staggered relative to each other; a spring 523, which is movably sleeved on the outside of the telescopic rod 522; and multiple slots are provided inside the guide baffle 3. The sliding blocks 521 cooperate with the inner cavity of the slots. By engaging the sliding blocks 521 between the insert shaft 51 and the guide baffle 3, the relative position between the insert shaft 51 and the guide baffle 3 can be limited, so that the rotation of the insert shaft 51 can drive the synchronous rotation of the guide baffle 3. The telescopic movement of the telescopic rod 522 makes the relative linear movement of the two sliding blocks 521 more stable. The elastic support of the spring 523 makes the cooperation between the sliding blocks 521 and the slots more stable.

[0043] The unlocking mechanism 53 includes: a rotating shaft 531, which is coaxially arranged with the through shaft 51; a turntable 532, which is connected to one end of the rotating shaft 531, and the turntable 532 has multiple guide grooves 5321, which are arranged in an inclined annular array relative to the center of the turntable 532; and a through sliding post 533, which is slidably inserted into the inner cavity of the guide groove 5321, and is fixedly installed on the sliding block 521. The unlocking mechanism 53 also includes a limiting sleeve 534, which is fixedly installed at the end of the through shaft 51. The shaft 531 and the limiting sleeve 534 are rotatably connected. The limiting sleeve 534 can limit the rotation of the shaft 531, making the rotation of the shaft 531 more stable. The rotation of the shaft 531 can synchronously drive the rotation of the turntable 532, so as to guide the linear movement of the through slide column 533 when the turntable 532 rotates. The inner wall of the guide groove 5321 can push the through slide column 533 to move centripetally towards the center of the turntable 532, so as to drive the centripetal movement of the sliding block 521. This allows the sliding block 521 to retract into the inside of the through shaft 51, thereby unlocking the relative position between the through shaft 51 and the guide baffle 3, so that the guide baffle 3 can be replaced after long-term use.

[0044] Example 2

[0045] Based on embodiment 1, a positioning pin 6 is movably inserted and installed at the other end of the handle 4, and multiple positioning holes that cooperate with the positioning pin 6 are arranged in a circular array on the main chute 1. By interlacing the positioning pin 6 with the positioning holes, it is convenient to position the angle of the handle 4 so as to position the angle of the guide baffle 3 in the inner cavity of the main chute 1. By setting multiple positioning holes, the guide baffle 3 can be positioned at multiple angles so as to more flexibly adjust the amount of material falling from the two outlets of the support chute 2.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
