Description

Technical Field

[0001] This utility model relates to the field of brick-making equipment technology, and in particular to a material feeding mechanism for brick-making equipment. Background Technology

[0002] A brick-making machine is a mechanical device used to produce masonry bricks. It typically uses stone powder, fly ash, slag, mineral slag, crushed stone, sand, and water as raw materials. The process involves mixing, extruding brick blanks, drying, baking, and sintering to produce masonry bricks. Existing brick-making machines include a feeding mechanism, a placing trolley, brick molds, a pressing head, and a vibrating box. The feeding mechanism feeds the mixed concrete raw materials into the placing trolley, which then transports and evenly distributes the concrete raw materials into the brick mold. The vibrating box vibrates the concrete raw materials within the brick mold to ensure even and dense compaction. Finally, the bricks are demolded and cured to form masonry bricks. The feeding mechanism of existing brick-making machines is located at the bottom... The material inlet is equipped with a material gate and a material gate cylinder that drives the material gate cylinder to open or close the material inlet. Because a large amount of concrete raw materials are needed to make bricks for large water conservancy projects, the material feeding amount is relatively large each time. Therefore, a relatively large material inlet and material gate are required to save material feeding time. However, because the material inlet is relatively large, the material gate has a long opening and closing stroke, making it impossible to open or close the material inlet quickly. The material feeding amount cannot be accurately controlled. In addition, the material gate will deform on the side not connected to the material gate cylinder due to the gravity of the concrete raw materials in the hopper. Gaps will appear between the material gate and the material inlet, which will easily lead to material leakage, affecting the uniformity of brick specifications and resulting in poor brick production quality.

[0003] In view of this, the applicant has deeply conceived and actively researched and tested improvements to address the numerous deficiencies and inconveniences caused by the imperfect structure of the feeding mechanism of the aforementioned brick-making equipment, and thus developed and designed this project. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding mechanism for a brick-making equipment. The feeding mechanism opens and closes the feeding port through two material gates, shortens the material gate opening and closing stroke, can quickly open or close the feeding port, makes the feeding amount easy to control, makes the brick specifications more uniform, and improves the brick-making effect.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A feeding mechanism for brick-making equipment includes a hopper, a feeding port located at the bottom of the hopper, a gate assembly, and a gate cylinder for driving the gate assembly to open or close the feeding port. The gate assembly has a first gate and a second gate pivotally connected to the gate cylinder. A first pivot plate is provided on each side of the first gate, and the two first pivot plates are rotatably pivotally connected to the side walls of the hopper via a first rotating shaft. A second pivot plate is provided on each side of the second gate, and the two second pivot plates are rotatably pivotally connected to the side walls of the hopper via a second rotating shaft. A first gear is provided on the first rotating shaft, and a second gear meshing with the first gear is provided on the second rotating shaft. One end of the gate cylinder is pivotally connected to the outer wall of the hopper, and the other end is pivotally connected to the first gate. When the gate cylinder drives the first gate to rotate outward or inward, the first and second gears mesh with each other to synchronously rotate the first and second gates outward to open the feeding port or inward to close the feeding port.

[0007] The first rotating shaft has the first gear at one end extending out of the first pivot plate, and the second rotating shaft has the second gear at one end extending out of the second pivot plate.

[0008] When the first and second material gates close their discharge ports, the inner sides of the first and second material gates overlap, and the inner side of the first material gate abuts against the bottom surface of the second material gate.

[0009] The first and second material gates are arc-shaped plates. When the first and second material gates are closed, the outer side and inner side of the first arc of the first material gate are higher than the lowest point of the first arc, and the outer side and inner side of the first arc of the second material gate are higher than the lowest point of the first arc.

[0010] In the vertical direction, the vertical position of the inner side of the first arc is lower than the vertical position of the inner side of the second arc, the vertical position of the inner side of the second arc is lower than the vertical position of the outer side of the first arc, and the vertical position of the outer side of the first arc is lower than the vertical position of the outer side of the second arc.

[0011] One end of the piston rod of the material gate cylinder is pivotally connected to the first material gate through a first universal joint; one end of the piston seat of the material gate cylinder is pivotally connected to the outer wall of the hopper through a second universal joint.

[0012] With the above structure, the feeding mechanism of the brick-making equipment of this utility model opens and closes the feeding port through two material gates, shortening the material gate opening and closing stroke, allowing for quick opening or closing of the feeding port, easy control of the feeding amount, more uniform brick specifications, and better brick-making effect. During feeding, when the piston rod of the material gate cylinder retracts, it pulls the first material gate outward, driving the first gear to rotate, which in turn meshes with the second gear. The rotation of the second gear drives the second material gate outward, and the first and second material gates rotate outward simultaneously to open the feeding port and begin feeding. When feeding is paused, when the piston rod of the material gate cylinder extends, it pushes the first material gate inward, driving the first gear to rotate... The first material gate rotates inward, engaging the second gear. This rotation causes the second material gate to rotate inward simultaneously, closing the discharge port and stopping material feeding. The feeding mechanism of this invention uses a material gate cylinder and the first and second gears to control the synchronous opening and closing of the first and second material gates, facilitating precise control of the feeding mechanism. Furthermore, through the meshing structure of the first and second gears, both the first and second material gates are subjected to the force of the material gate cylinder, and the inner sides of the first and second material gates rotate to overlap, completely closing the discharge port and preventing gaps under the weight of the concrete material, effectively preventing material leakage.

[0019] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0020] Please see Figures 1 to 4 This utility model discloses a feeding mechanism for a brick-making device. The feeding mechanism includes a hopper 1, a feeding port 2 located at the bottom of the hopper 1, a material gate assembly 3, and a material gate cylinder 4 for driving the material gate assembly 3 to open or close the feeding port 2. The material gate assembly 3 has a first material gate 31 and a second material gate 32 pivotally connected to the material gate cylinder 4. A first pivot plate 311 is provided on each side of the first material gate 31, and the two first pivot plates 311 are pivotally connected to the two side walls 11 of the hopper 1 via a first rotating shaft 312. A second pivot plate 321 is provided on each side of the second material gate 32, and the two second pivot plates 321 are pivotally connected to the two side walls 11 of the hopper 1 via a first rotating shaft 312. 21 is pivotally connected to the two side walls 11 of the hopper 1 via a second rotating shaft 322; a first gear 313 is provided on the first rotating shaft 312, and a second gear 323 is provided on the second rotating shaft 322 to mesh with the first gear 313; one end of the material gate cylinder 4 is pivotally connected to the outer wall of the hopper 1, and the other end is pivotally connected to the first material gate 31; when the material gate cylinder 4 drives the first material gate 31 to rotate outward or inward, the first gear 313 and the second gear 323 mesh with each other to realize that the first material gate 31 and the second material gate 32 rotate outward to open the discharge port 2 or rotate inward to close the discharge port 2.

[0021] The feeding mechanism of this brick-making equipment uses two material gates to open and close the feeding port 2, shortening the opening and closing stroke of the material gate 3. This allows for quick opening or closing of the feeding port 2, easy control of the feeding amount, more uniform brick specifications, and better brick-making results. During feeding, when the piston rod 41 of the material gate cylinder 4 retracts, it pulls the first material gate 31 outward, driving the first gear 313 to rotate, which in turn meshes with the second gear 323. The rotation of the second gear 323 drives the second material gate 32 outward, and the first and second material gates 31 and 32 rotate simultaneously to open the feeding port 2, initiating feeding. When feeding stops, when the piston rod 41 of the material gate cylinder 4 extends, it pushes the first material gate 31 inward, driving the first gear 313 to rotate, which in turn meshes with the second gear 323. When gear 323 rotates, the second gear 323 rotates, causing the second material gate 32 to rotate inward. The first material gate 31 and the second material gate 32 rotate inward simultaneously to close the discharge port and stop the material feeding. The material feeding mechanism of this utility model controls the synchronous opening and closing of the first material gate 31 and the second material gate 32 through a material gate cylinder 4 and the first gear 313 and the second gear 323, which facilitates precise control of the material feeding mechanism. Moreover, through the meshing structure of the first gear 313 and the second gear 323, both the first material gate 31 and the second material gate 32 are subjected to the force of the material gate cylinder 4, and the inner side of the first material gate 31 and the inner side of the second material gate 32 rotate to overlap each other, which can completely close the discharge port 2, and no gaps will appear under the weight of the concrete raw materials, which can effectively prevent material leakage.

[0022] In this invention, the first rotating shaft 312 has a first gear 313 at one end extending out of the first pivot plate 311, and the second rotating shaft 322 has a second gear 323 at one end extending out of the second pivot plate 321. The first gear 313 and the second gear 323 are located on the outer side and mesh with each other, which enables the first material gate 31 and the second material gate 32 to rotate outward to open the discharge port 2 or rotate inward to close the discharge port 2, and the discharge port 2 can be opened or closed quickly.

[0023] When the first material gate 31 and the second material gate 32 close the discharge port 2, the inner sides of the first material gate 31 and the second material gate 32 have overlapping portions, and the inner side of the first material gate 31 abuts against the bottom surface of the second material gate 32. Because the inner sides of the first material gate 31 and the second material gate 32 have overlapping portions, when the first material gate 31 and the second material gate 32 deform under the gravity of the concrete raw materials, the overlapping portions can completely close the discharge port 2 without gaps, effectively preventing material leakage. Moreover, since the first material gate 31 and the material gate cylinder 4 are pivotally connected, the first material gate 31 can be stably abutted against the bottom surface of the second material gate 32 by the force of the material gate cylinder 4, so that the first material gate 31 and the second material gate 32 can firmly close the discharge port 2, which can prevent material leakage.

[0024] The first material gate 31 and the second material gate 32 of this utility model are arc-shaped plates. When the first material gate 31 and the second material gate 32 close the discharge port 2, the outer side 314 and the inner side 315 of the first arc of the first material gate 31 are both higher than the lowest point 316 of the first arc, and the outer side 324 and the inner side 325 of the second arc of the second material gate 32 are both higher than the lowest point 326 of the second arc. When the discharge port 2 is closed, the arc surfaces of the first material gate 31 and the second material gate 32 face downwards, and the stress point is at the lowest point of the arc, which can prevent material leakage and make the two material gates more stable in opening and closing the discharge port 2.

[0025] In the vertical direction, the vertical position of the inner side 315 of the first arc is lower than the vertical position of the inner side 325 of the second arc, the vertical position of the inner side 323 of the second arc is lower than the vertical position of the outer side 314 of the first arc, and the vertical position of the outer side 314 of the first arc is lower than the vertical position of the outer side 325 of the second arc. The inner sides of the first material gate 31 and the second material gate 32 overlap, and the arc inclination angles of the two material gates are different, so they can stably abut against each other, firmly closing the feed port 2 and preventing material leakage.

[0026] In this invention, one end of the piston rod 41 of the material gate cylinder 4 is pivotally connected to the first material gate 31 via a first universal joint 43; one end of the piston seat 42 of the material gate cylinder 4 is pivotally connected to the outer wall of the hopper 1 via a second universal joint 44; the material gate cylinder 4 can more smoothly push or pull the first material gate 31 to rotate, and conveniently drive the first material gate 31 and the second material gate 32 to open or close the discharge port 2.

[0027] The above embodiments and accompanying drawings are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
