Description

Technical Field

[0001] This utility model relates to the technical field of building material feeding equipment, specifically a building material feeding arch breaking device. Background Technology

[0002] The "arching" effect that occurs when building materials accumulate in silos or hoppers is essentially a result of the combined forces between the material particles and external constraints, disrupting the natural equilibrium of the material's descent. When building materials pile up above the silo outlet, friction is generated between the particles due to compression. Combined with the material's own weight, the adsorption force on the particle surfaces, and the friction from the silo wall, these forces partially offset the weight, causing the material particles to form a relatively stable "arch" structure. When the supporting force of this structure is sufficient to resist the weight and downward trend of the material below, it will block the material flow, forming an "arching" blockage. This is commonly seen in scenarios where the silo outlet diameter is small, the material moisture content is high, or the particle size distribution is uneven.

[0003] However, existing technologies still have significant shortcomings, such as: Although existing technologies have devices that use levers to break up arches, and levers can effectively remove bonded building material raw materials from the hopper, raw materials can still adhere to the lever itself and its supporting components. Prolonged adhesion can easily lead to hopper blockage. Utility Model Content

[0004] The purpose of this utility model is to provide a building material feeding and arch breaking device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A building material feeding and arch-breaking device includes a frame and a feeding hopper. An arch-breaking ring is rotatably arranged in the frame, a fixing block is fixedly arranged on the arch-breaking ring, and an arch-breaking rod is fixedly arranged on the fixing block. A rotating rod is rotatably mounted on the frame, an idler wheel is fixedly mounted on the rotating rod, a gear ring is fixedly sleeved on the outer side of the arch-breaking ring, the gear ring meshes with the idler wheel for transmission, a drive assembly is fixedly mounted on the frame, a drive gear is fixedly mounted on the output shaft of the drive assembly, and the drive gear also meshes with the idler wheel; A fixed rod is fixedly installed on the frame, a striking plate is rotatably installed on the fixed rod, a torsion spring is installed between the striking plate and the fixed rod, and a paddle is fixedly installed on the rotating rod.

[0006] Preferably, a plurality of support wheels are rotatably mounted on the frame, and the support wheels are in contact with the outer edge of the arch-breaking ring to provide support for the arch-breaking ring.

[0007] Preferably, an annular flange is fixedly provided on the arch-breaking ring, and an annular groove is provided on the support wheel, with the annular flange cooperating with the annular groove.

[0008] Preferably, several arch-breaking crossbeams are fixedly installed on the arch-breaking rod.

[0009] Preferably, a number of elastic bristles are fixedly provided on the side of the arch-breaking rod facing the hopper.

[0010] Preferably, the drive assembly includes a drive motor and a reducer. The reducer is fixedly mounted on the frame. The drive motor is fixedly connected to the reducer. The shaft of the drive motor is fixedly connected to the input end of the reducer. The output shaft of the reducer is fixedly connected to the drive gear.

[0011] Preferably, the frame has several maintenance holes, and a cover plate is fixedly installed on the frame at the position of the maintenance hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This device integrates an arch-breaking rod, an arch-breaking beam, and elastic bristles, simultaneously achieving arch-breaking and wall-cleaning functions driven by the arch-breaking ring. As the arch-breaking beam rotates, it directly agitates the building material within the hopper, breaking up the arched accumulation structure and resolving the blockage problem at its source. Simultaneously, the elastic bristles closely adhere to the inner wall of the hopper, rotating synchronously with the arch-breaking rod to continuously brush away adhering material, preventing material residue buildup that could narrow the discharge channel. Compared to traditional devices with only a single arch-breaking function, this device eliminates the need for an additional wall-cleaning mechanism, achieving simultaneous "arch-breaking and wall-cleaning," significantly improving discharge efficiency and reducing the frequency of manual cleaning.

[0013] In use, the drive motor is first started, and the power output by the drive motor is transmitted to the reducer. After being reduced in speed and torque by the reducer, the drive gear on its output shaft rotates. The drive gear drives the idler gear to rotate through gear meshing, and the idler gear meshes with the gear ring on the outer side of the arch-breaking ring. Therefore, the power is further transmitted to the gear ring, and finally drives the arch-breaking ring to rotate stably in the frame. This process completes the transmission of power from the drive end to the execution end (arch-breaking ring).

[0014] When the arch-breaking ring rotates, its inner wall drives the arch-breaking rod to rotate synchronously through the fixed block: the arch-breaking beam on the arch-breaking rod rotates together, directly agitating the building material raw materials accumulated in the hopper, breaking the arch structure formed by the extrusion of the raw materials, solving the material blockage problem from the root, and realizing the core function of "arch breaking"; at the same time, the elastic bristles on the side of the arch-breaking rod facing the hopper are closely attached to the inner wall of the hopper, continuously brushing the wall surface as the arch-breaking rod rotates, brushing off the raw materials adhering to the inner wall of the hopper, avoiding the accumulation of raw materials on the wall surface that would cause the material discharge channel to narrow, and ensuring smooth material discharge.

[0015] Simultaneously, the rotation of the idler wheel drives the fixed rotating rod to rotate, and the paddle on the rotating rod rotates along with it, intermittently pushing the striking plate on the fixed rod to deflect around the axis (during this process, the striking plate compresses the torsion spring to store elastic potential energy). When the paddle rotates to the point of separation from the striking plate, the striking plate quickly returns to its original position under the elastic restoring force of the torsion spring, and its end strikes the arch-breaking ring, shaking off the raw material adhering to the surface of the arch-breaking ring, preventing the raw material from accumulating and clumping on the arch-breaking ring, thus affecting its rotational flexibility and achieving a "self-cleaning" auxiliary function.

[0016] In addition, throughout the entire operation, the support wheels set along the circumference of the arch-breaking ring on the frame always play a stabilizing role: the annular flange of the outer edge of the arch-breaking ring is embedded in the annular groove of the support wheel, which not only restricts the axial displacement of the arch-breaking ring, but also provides radial support through the fit between the wheel rim and the outer edge of the arch-breaking ring, ensuring that the arch-breaking ring always rotates stably along a fixed trajectory, allowing the arch-breaking rod and arch-breaking beam to act precisely on the raw material accumulation area, avoiding incomplete local arch breaking due to the shaking of the arch-breaking ring.

[0017] If internal components of the device (such as drive gears, idler gears, etc.) need to be inspected, the cover plate at the maintenance hole on the frame can be opened, and the device can be operated directly through the maintenance hole without disassembling the entire device, which will not affect the subsequent rapid recovery operation.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: This device consists of a frame 1 and a hopper 2. The hopper 2 is funnel-shaped, with its bottom fixedly positioned above the frame 1, forming an vertical arrangement. A breaking ring 3 is rotatably mounted in the middle of the frame 1. The breaking ring 3 is annular, with a toothed ring 8 fixedly fitted circumferentially on its outer wall, forming an integral structure with the breaking ring 3. A fixing block 4 is fixedly mounted on the inner wall of the breaking ring 3. The fixing block 4 is block-shaped, and one end of a breaking rod 5 is fixedly connected to the fixing block 4. The breaking rod 5 extends radially along the breaking ring 3, and several breaking crossbeams 51 are fixedly mounted axially on the breaking rod 5. The breaking crossbeams 51 are perpendicular to the breaking rod 5 and spaced apart. Simultaneously, several elastic bristles 52 are fixedly mounted on the side of the breaking rod 5 facing the hopper 2, with the ends of the elastic bristles 52 adhering to the inner wall of the hopper 2, forming a close contact.

[0022] When the arch-breaking ring 3 rotates in the frame 1, the arch-breaking ring 3 drives the arch-breaking rod 5 to rotate synchronously through the fixed block 4. The arch-breaking crossbeam 51 on the arch-breaking rod 5 agitates the building material raw materials in the feeding hopper 2 during the rotation, thereby breaking the arch-shaped accumulation structure of the raw materials and realizing the arch-breaking function. At the same time, the elastic bristles 52 rotate with the arch-breaking rod 5 and continuously brush the inner wall of the feeding hopper 2, brushing off the raw materials adhering to the inner wall of the feeding hopper 2, avoiding the accumulation of raw materials on the wall surface, and ensuring the smooth feeding of raw materials.

[0023] A rotating rod 6 is rotatably mounted on one side of the frame 1. An idler wheel 7 is fixedly mounted on the rod body of the rotating rod 6. The teeth of the idler wheel 7 mesh with the teeth of the gear ring 8 on the outer side of the arch-breaking ring 3, forming a transmission connection. A drive assembly is also fixedly mounted on the frame 1. The drive assembly consists of a drive motor 91 and a reducer 92. The reducer 92 is fixed to the surface of the frame 1 by bolts. The housing of the drive motor 91 is fixedly connected to the housing of the reducer 92. The output shaft of the drive motor 91 is connected to the input end of the reducer 92 by a coupling to realize direct power transmission. A drive gear 10 is fixedly mounted on the output shaft of the reducer 92. The teeth of the drive gear 10 mesh with the teeth of the idler wheel 7.

[0024] Start the drive motor 91. The output shaft of the drive motor 91 rotates and drives the input end of the reducer 92 to rotate. After the reducer 92 reduces the power and increases the torque, its output shaft drives the drive gear 10 to rotate. The drive gear 10 drives the idler gear 7 and the rotating rod 6 to rotate through meshing with the idler gear 7. The idler gear 7 then drives the arch-breaking ring 3 to rotate in the frame 1 through meshing with the gear ring 8, thereby providing a power source for the arch-breaking action of the arch-breaking rod 5.

[0025] A plurality of support wheels 15 are rotatably mounted on the frame 1 along the circumference of the arch-breaking ring 3. The rims of the support wheels 15 are in contact with the outer surface of the arch-breaking ring 3, forming circumferential support for the arch-breaking ring 3. An annular flange 31 is fixedly mounted on the outer edge of the arch-breaking ring 3, and the annular flange 31 extends circumferentially along the arch-breaking ring 3. Correspondingly, an annular groove 151 is formed on the wheel surface of the support wheels 15. The shape of the annular groove 151 is adapted to the annular flange 31, and the annular flange 31 is embedded in the annular groove 151, forming a mating structure.

[0026] When the arch-breaking ring 3 rotates in the frame 1, the annular flange 31 on the arch-breaking ring 3 slides in the annular groove 151 of the support wheel 15. Through this engagement, the support wheel 15 provides circumferential positioning and radial support for the arch-breaking ring 3, preventing axial displacement or radial swaying of the arch-breaking ring 3 during rotation, and ensuring that the arch-breaking ring 3 can stably drive the arch-breaking rod 5 to perform arch-breaking operations.

[0027] A fixed rod 11 is fixedly mounted on the frame 1. The fixed rod 11 is rod-shaped, and one end of it is fixedly connected to the side wall of the frame 1. A striking plate 12 is rotatably mounted on the fixed rod 11. The striking plate 12 is connected to the fixed rod 11 via a rotating shaft and can rotate around the shaft. A torsion spring 13 is provided between the striking plate 12 and the fixed rod 11. The torsion spring 13 is sleeved on the rotating shaft, with one end connected to the fixed rod 11 and the other end connected to the striking plate 12, providing elastic force for the striking plate 12 to reset. A paddle 14 is fixedly mounted on the body of the rotating rod 6. The paddle 14 is a plate-shaped structure and rotates synchronously with the rotation of the rotating rod 6.

[0028] It should be noted that the torsion spring on the striking plate has sufficient elasticity to cause the arch-breaking ring to vibrate when it is turned by the lever.

[0029] When the rotating rod 6 rotates, the paddle 14 rotates accordingly, intermittently pushing the striking plate 12 to rotate around the axis, causing the striking plate 12 to deflect against the elastic force of the torsion spring 13. When the paddle 14 separates from the striking plate 12, the striking plate 12 quickly returns to its original position under the elastic restoring force of the torsion spring 13, and its end strikes the arch-breaking ring 3, causing the building material adhering to the arch-breaking ring 3 to be shaken off, preventing the material from accumulating on the arch-breaking ring 3, and ensuring the continuous and effective arch-breaking operation. Several maintenance holes 16 are provided on the frame 1, and a cover plate 17 is fixedly installed on the frame 1 at the position of the maintenance hole 16.

[0030] Working principle: During material feeding, the drive motor 91 is started, which drives the reducer 92 to run. The reducer 92 outputs a large torque and drives the drive gear 10 to rotate. The drive gear 10 transmits power to the gear ring 8 through the idler wheel 7. The gear ring 8 drives the arch-breaking ring 3 to rotate. The arch-breaking ring 3 drives the arch-breaking rod 5 and the arch-breaking beam 51 to break the arches of the building material raw materials in the feeding hopper 2. At the same time, the elastic bristles 52 on the arch-breaking rod 5 brush off the raw materials on the inner wall of the feeding hopper 2. During this process, the idler wheel 7 synchronously drives the rotating rod 6 to rotate. The paddle 14 on the rotating rod 6 intermittently paddles the striking plate 12. The striking plate 12 is a lever that requires effort. When the striking plate 12 separates from the paddle 14, the striking plate 12 resets under the action of the torsion spring 13 and strikes the arch-breaking ring 3, causing the raw materials adhering to the arch-breaking ring 3 to be knocked off. In addition, the support wheel 15 provides stable support for the arch-breaking ring 3 through the cooperation of the annular flange 31 and the annular groove 151; if it is necessary to inspect the inside of the device, the cover plate 17 can be opened and the operation can be carried out through the maintenance hole 16.

[0031] 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.
