Abstract
Description
Technical Field
[0001] The utility model belongs to the field of loosening devices, and more specifically, particularly relates to a loosening device for preventing stone powder from flying. Background Art
[0002] Stone powder is evenly introduced onto a conveyor belt through a feed bin and undergoes a series of processes through the conveyor belt. Among them, there is a loosening process for the stone powder. When the agglomerated stone powder moves under the loosening device, the loosening device rotates to roll and loosen the agglomerates.
[0003] Based on the above, the inventor of the present utility model found that the existing stone powder loosening devices mainly have the following deficiencies, such as:
[0004] When the loosening device loosens the stone powder by rotating, since the loosening rod is relatively light itself, when encountering the stone powder through the inertia of rotation, it will be slightly blocked. After the loosening is completed, at the moment of separating from the stone powder, the stone powder will be thrown out together by inertia, which is likely to cause a large amount of stone powder to fly.
[0005] Therefore, it is necessary to propose a loosening device for preventing stone powder from flying. Content of the Utility Model
[0006] In order to solve the above technical problem that when the loosening device loosens the stone powder by rotating, since the loosening rod is relatively light itself, when encountering the stone powder through the inertia of rotation, it will be slightly blocked. After the loosening is completed, at the moment of separating from the stone powder, the stone powder will be thrown out together by inertia, which is likely to cause a large amount of stone powder to fly.
[0007] The purpose and effect of a loosening device for preventing stone powder from flying according to the present utility model are achieved by the following specific technical means:
[0008] Its structure includes an anti-dust frame, a baffle, and a loosening rod. The loosening rod is installed on the inner wall of the anti-dust frame, and its rotating shaft penetrates the anti-dust frame and is connected to a motor. The baffle is fixed on the inner surface of the anti-dust frame. The loosening rod is located above the stone powder conveyor belt;
[0009] The loosening rod includes a swing plate, a main pressure rod, a limit plate, a connecting shaft, an inner groove, a sinker, and an extrusion body. The inner groove is integrated with the main pressure rod. The swing plate is installed in the inner groove and can swing. The main pressure rod is installed in the inner groove of the limit plate and is supported by the extrusion body. The sinker is integrated with the main pressure rod and is installed at the end. When the main pressure rod is rotated to a certain angle, the swing plate will swing open through its own drooping force. The sinker swings through its own gravity to droop the main pressure rod and counterweight it, preventing the main pressure rod from bouncing stone powder through inertia and resistance. The extrusion body is made of elastic rubber material and has soft supporting force for the main pressure rod, so that the main pressure rod can extrude the extrusion body when it is under weight and droops. The support of the extrusion body can prevent the connecting part from shaking when it swings under force. The extrusion body will support the connecting part to return to its position if the drooping gravity is lost. The maximum expandable angle between the swing plate and the main pressure rod is 45 degrees.
[0010] As a further improvement of the utility model, the connecting shaft is connected to the outer side of the limit plate for connection and rotation, the plate blocks part of the raised stone powder for interception, the swing plate is a rectangular structure that occupies a large area of the main pressure rod for swinging counterweight, and when the main pressure rod rotates from the lower end to the upper end, the counterweight is pressed down by its own internal gravity.
[0011] As a further improvement of the present invention, the limit plate includes a limit groove and a fixed shaft. The fixed shaft passes through the main pressure rod to fix the active center point. The limit groove limits the maximum swing range of the main pressure rod. The extrusion body fits the inner surface of the limit groove to support the main pressure rod.
[0012] As a further improvement of the present invention, the main pressure rod includes a movable sinker, a limiting track, and a main rod. The movable sinker is placed inside the limiting track for movement. The limiting track and the main rod are an integrated structure. The movable sinker moves along the limiting track in a downward direction to change the center of gravity of the main pressure rod, and the limiting track limits the moving range of the movable sinker.
[0013] As a further improvement of the utility model, the movable sinker includes a counterweight block, an extension layer, and a protective layer. The counterweight block is embedded in the extension layer. Counterweight blocks are installed at the upper and lower ends of the extension layer. The protective layer plays a protective and buffering role when the movement of the connecting part stops. The protective layer is made of hard rubber and is symmetrically distributed in an arc-shaped structure.
[0014] As a further improvement of the present invention, the swing plate includes a rebound body, an extension plate, and a counterweight core. The counterweight core is embedded in the inner end of the extension plate, and the rebound body is installed on the inner side of an end of the extension plate away from the counterweight core. The rebound body itself has resilience, and supports the extension plate for swinging and assists its return. The counterweight core drives the extension plate to swing vertically toward the bottom surface at a certain angle through its own gravity.
[0015] Compared with the prior art, the utility model has the following beneficial effects:
[0016] 1. The main pressure rod will loosen the stone powder placed on the lower conveyor belt. When the main pressure rod rotates to the lowest end and contacts the stone powder to loosen it, the moving sinker inside the main rod will slide downward along the limiting channel, enabling the main pressure rod to swing downward under the force of the counterweight. The main pressure rod continues to rotate along the connecting shaft. Through the unique counterweight of the sinker and the limiting channel for the main pressure rod, the main pressure rod will swing along the inclined direction of the limiting groove. When it disengages after loosening the stone powder, it has a certain gravity and will not cause the stone powder to fly up due to the resistance of the stone powder and the inertia of rotation. Through the counterweight of the sinker and the limiting channel, the main pressure rod exerts pressure on the extrusion body from the lowest end to the highest end, making the main pressure rod in a downward inclined state. When the loosening device rotates to loosen the stone powder, it can control and press down the inertia of the loosening rod, so that it always maintains a downward inclined state for half the distance after contacting the stone powder, preventing the stone powder from being carried up and flying.
[0017] 2. When the main pressure rod continues to rotate after reaching the lowest point and contacting the stone powder, the swing plate assembled with the main pressure rod will swing vertically downward to the bottom surface due to the gravity of its own counterweight core. During the process of the main pressure rod rotating from the lowest point to the highest point, the swing plate will continuously maintain a downward vertical unfolding angle, exerting a downward pulling force on the main pressure rod, so that the main pressure rod has a certain returning swing force during the second half of the rotation process, making the main pressure rod in a downward inclined state. When the loosening rod rotates after contacting the stone powder in the second half, it can play a role in pulling it downward, preventing the stone powder from being thrown out due to the inertia of rotation and the resistance of the stone powder.

DETAILED DESCRIPTION
[0026] The utility model is further described below in conjunction with the accompanying drawings:
[0027] Example 1
[0028] As attached Figure 1 To Attachment Figure 6 As shown:
[0029] The utility model provides a loosening device for preventing stone dust from flying, and the structure thereof comprises an anti-ash frame 1, a baffle 2, and a loosening rod 3. The loosening rod 3 is installed on the inner wall of the anti-ash frame 1, and its rotating shaft penetrates the anti-ash frame 1 and is connected with a motor. The baffle 2 is fixed to the inner surface of the anti-ash frame 1, and the loosening rod 3 is located above the stone dust conveyor belt.
[0030] The loosening rod 3 includes a swing plate 31, a main pressure rod 32, a limit plate 33, a connecting shaft 34, an inner groove 35, a sinker 36, and an extrusion body 37. The inner groove 35 is integrated with the main pressure rod 32. The swing plate 31 is installed in the inner groove 35 and can swing. The main pressure rod 32 is installed in the inner groove of the limit plate 33 and supported by the extrusion body 37. The sinker 36 is integrated with the main pressure rod 32 and installed at the end. When the main pressure rod 32 rotates to a certain angle, the swing plate 31 will swing open by its own drooping force, and the sinker 36 will swing open by its own gravity. The main pressure rod 32 is dynamically drooped with a counterweight to prevent the main pressure rod 32 from bouncing the stone powder through inertia and resistance. The extrusion body 37 is made of elastic rubber material and has a soft supporting force for the main pressure rod 32, so that the main pressure rod 32 can sag under weight to squeeze the extrusion body 37. The support of the extrusion body 37 can prevent the connecting part from shaking when it swings under force. Without the drooping gravity, the extrusion body 37 will support the connecting part to return to its original position. The maximum expandable angle between the swing plate 31 and the main pressure rod 32 is 45 degrees. The main pressure rod 32 is provided with nine and is evenly distributed in a circle.
[0031] Among them, the connecting shaft 34 is connected to the outside of the limiting disc 33 for connecting and rotating. The plate 2 blocks part of the lifted stone powder for interception. The swing plate 31 is a rectangular structure that occupies a large area of the main pressure rod 32 for swinging counterweight. When the main pressure rod 32 rotates from the lowest end to the upper end, it is weighted and pressed down by its own internal gravity. The extrusion body 37 is a fan-shaped structure, which can help the connecting part to perform extrusion and swing better.
[0032] Among them, the limiting disc 33 includes a limiting groove a1 and a fixed shaft a2. The fixed shaft a2 passes through the inside of the main pressure rod 32 to fix the movable center point. The limiting groove a1 limits the maximum swing range of the main pressure rod 32. The extrusion body 37 fits on the inner surface of the limiting groove a1 to support the main pressure rod 32. The limiting groove a1 is provided with nine, evenly distributed in a circle.
[0033] Among them, the main pressure rod 32 includes a moving sinker s1, a limiting channel s2, and a main rod s3. The moving sinker s1 is placed inside the limiting channel s2 for movement. The limiting channel s2 and the main rod s3 are of an integrated structure. The moving sinker s1 moves along the limiting channel s2 in the downward direction to change the center of gravity of the main pressure rod 32 for counterweight. The limiting channel s2 limits the moving range of the moving sinker s1. The limiting channel s2 is provided with two, symmetrically distributed on the left and right sides of the main rod s3.
[0034] Among them, the moving sinker s1 includes a counterweight block x1, an extension layer x2, and a protective layer x3. The counterweight block x1 is embedded inside the extension layer x2. The counterweight block x1 is installed at the upper and lower ends of the extension layer x2. The protective layer x3 plays a protective and buffering role when the movement of the connecting part stops. The protective layer x3 is made of hard rubber material and is symmetrically distributed in an arc structure. The counterweight block x1 drives the overall center of gravity to slide by its own gravity.
[0035] Specific usage method and function of this embodiment:
[0036] In the present utility model, when stone powder is conveyed through a conveyor belt, its loose rod 3 is driven to rotate by a rotating motor through a connecting shaft 34. The main pressing rod 32 will loosen the stone powder placed on the lower conveyor belt. When the main pressing rod 32 rotates to the lowest end and contacts the stone powder to loosen it, the moving sinker s1 inside the main rod s3 will slide downward along the limiting channel s2. The movement and stop of the moving sinker s1 are protected by the protective layer x3 equal to the extension layer x2 and the limiting channel s2. The counterweight block x1 plays the main counterweight role, enabling the main pressing rod 32 to swing downward under the force of the counterweight. The main pressing rod 32 continuously rotates along the connecting shaft 34. When the main pressing rod 32 disengages from the stone powder, the sinker 36 and the limiting channel s2 further counterweight the main pressing rod 32, causing the main pressing rod 32 to extrude the extrusion body 37. The main pressing rod 32 will swing along the inclination direction of the limiting groove a1, so that when it disengages after loosening the stone powder, it has a certain gravity and will not lift the stone powder by the resistance of the stone powder and the inertia of rotation. Through the counterweight of the sinker 36 and the limiting channel s2, the main pressing rod 32 extrudes the extrusion body 37 when it rotates from the lowest end to the highest end, making the main pressing rod 32 in a downward inclined state to avoid lifting the stone powder and causing it to fly.
[0037] Embodiment 2
[0038] As shown in the Figure 7 appendix
[0039] Among them, the swing plate 31 includes a resilient body g1, an extension plate g2, and a counterweight core g3. The counterweight core g3 is embedded at the inner end of the extension plate g2. The resilient body g1 is installed on the inner side of the end of the extension plate g2 away from the counterweight core g3. The resilient body g1 has its own resilience and supports the swing of the extension plate g2 to assist its return. The counterweight core g3 drives the extension plate g2 to swing vertically towards the bottom surface at a certain angle by its own gravity. The swing of the extension plate g2 exerts a certain gravitational pull on the main pressing rod 32, so that the main pressing rod 32 will not bounce upward when encountering resistance during rotation.
[0040] The specific usage and function of this embodiment are as follows:
[0041] In the present utility model, when the loose rod 3 rotates together with the rotation motor and the main pressing rod 32 rotates and loosens the stone powder, when the main pressing rod 32 continues to rotate after reaching the lowest position and contacting the stone powder, the swing plate 31 assembled with the main pressing rod 32 will swing vertically downward under the gravity of its own counterweight core g3 and unfold from the inner groove 35. Its resilient body g1 will be subjected to the force of bending support to assist the extension plate g2 to swing open. During the process of the main pressing rod 32 rotating from the bottom to the top, the swing plate 31 will continuously maintain the unfolded angle perpendicular to the downward direction to exert a downward pulling force on the main pressing rod 32, so that the main pressing rod 32 has a certain returning swing force during the latter half of the rotation process, making the main pressing rod 32 in a downward inclined state to prevent the stone powder from being carried out by rotation.
[0042] Any technical solution using the technical solution described in the present utility model, or any technical solution designed by those skilled in the art inspired by the technical solution of the present utility model and achieving the above technical effects shall fall within the protection scope of the present utility model.
