Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of concrete production equipment, and more specifically, to a stone feeding buffer device for concrete production. Background Technology

[0002] Concrete production involves bringing together the entire process from individual construction sites—including raw material selection, mix design, admixture and additive selection, concrete mixing, and concrete delivery to the construction site—at a batching plant. The batching plant then manages and supplies various finished products to construction companies in commodity form.

[0003] Existing batching plants directly add the mixture into the plant during feeding, which easily impacts the bottom of the plant and causes damage. To mitigate the impact, existing batching plants add a buffer plate at the feed hopper, but this easily leaves mixture residue on the buffer plate, affecting its use. Existing aggregate feeding buffer devices for commercial concrete production have poor buffering effect and are inconvenient to clean the residue on the buffer plate.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a stone feeding buffer device for concrete production, which solves the technical problem that existing mixing plants add a buffer plate at the feeding cylinder to reduce the buffering force, but such a setting is very easy to leave the mixture on the buffer plate, affecting the use.

[0006] According to one aspect, at least one embodiment of this disclosure provides a stone feed buffer device for concrete production, comprising:

[0007] The enclosure includes a feed inlet and a separation outlet, wherein the feed inlet is located on the top of the enclosure and the separation outlet is located on the inner surface of the enclosure.

[0008] The drive motor and the preliminary buffer assembly are provided, wherein the drive motor is disposed on the side surface of the housing and the preliminary buffer assembly is disposed inside the housing;

[0009] The discharge hood and the secondary buffer assembly are provided, wherein the discharge hood is disposed on one side of the bottom of the outer shell, and the secondary buffer assembly is disposed at the bottom of the outer shell;

[0010] The preliminary buffer assembly includes a rotating roller, which is rotatably connected inside the housing. The rotating roller is connected to the output end of the drive motor, and a plurality of receiving racks are provided on the surface of the rotating roller.

[0011] As a further technical solution, the surface of the receiving rack is provided with a groove, and a plurality of first buffer springs are provided on the inner surface of the groove, with a buffer plate connected to the upper end of the first buffer spring.

[0012] As a further technical solution, the secondary buffer assembly includes a movable bottom opening, which is located at the bottom of the outer shell. Connecting blocks are provided at the lower ends of both sides of the outer shell, and connecting rods are movably connected within the connecting blocks.

[0013] As a further technical solution, a fixing block is fixedly connected to one end of the connecting rod, a movable plate is connected between the fixing blocks, a second spring is fitted on the connecting rod, and a second motor is installed on the side surface of the outer shell.

[0014] As a further technical solution, the side end face of the movable plate is provided with an extension plate, the surface of the extension plate is provided with a movable hole, the output end of the second motor is provided with an eccentric shaft bracket, the lower end of the eccentric shaft bracket is movably fitted into the movable hole, and the surface of the movable plate is provided with a raised layer.

[0015] As a further technical solution, baffles are provided at both ends of the surface of the movable plate.

[0016] As a further technical solution, a rear groove is provided at one end of the bottom of the outer shell, and the inner surface of the rear groove is higher than the height of the raised layer.

[0017] As a further technical solution, the movable plate is installed at an inclined angle, the convex layer extends downward in a stepped shape, and the surface of the convex layer has a planar structure.

[0018] As a further technical solution, the movable hole has a transverse opening structure, and the eccentric shaft bracket is slidably fitted to the inner wall of the movable hole.

[0019] As a further technical solution, the interior of the outer shell has a circular structure.

[0020] The beneficial effects of the embodiments disclosed herein are as follows:

[0021] 1. The beneficial effect of the preliminary buffer assembly in this disclosure is that the design of the rotating roller and the receiving frame can receive stones in sequence during rotation, control the amount of stones received each time, and avoid accumulation. The groove on the receiving frame, the first buffer spring and the buffer plate cooperate with each other. When the stones fall, the spring is compressed by the buffer plate, which effectively absorbs the impact force and slows down the falling speed of the stones, thus achieving preliminary buffering of the stones and protecting the bottom of the equipment from large impacts.

[0022] 2. In this disclosure, the secondary buffer assembly has significant advantages. The combination of the movable bottom opening, connecting rod, fixed block, movable plate, and second spring enables the movable plate to have buffering and rebound capabilities. The second motor drives the eccentric shaft frame, causing the movable plate to reciprocate. In conjunction with the inclined movable plate and stepped protrusions, the rolling speed of the stones can be further reduced, enhancing the buffering effect. The baffles at both ends of the movable plate prevent particles from entering the gaps and causing wear. The design of the rear groove prevents stones from getting stuck, ensuring the stable operation of the secondary buffer assembly and improving the overall buffering performance.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0032] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Therefore, they should not be construed as limitations on this disclosure.

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] like Figures 1-4 As shown, it illustrates a concrete production aggregate feeding buffer device according to an embodiment of the present disclosure, comprising:

[0036] The outer shell 1, the feed inlet 2, and the separation port 3 are provided. The feed inlet 2 is located on the top of the outer shell 1, and the separation port 3 is located on the inner surface of the outer shell 1.

[0037] The drive motor 4 and the preliminary buffer assembly 6 are provided. The drive motor 4 is located on the side surface of the housing 1 and the preliminary buffer assembly 6 is located inside the housing 1.

[0038] The discharge hood 5 and the secondary buffer assembly 7 are provided. The discharge hood 5 is located on one side of the bottom of the outer shell 1, and the secondary buffer assembly 7 is located at the bottom of the outer shell 1.

[0039] The preliminary buffer assembly 6 includes a rotating roller 6-1, which is rotatably connected inside the housing 1. The rotating roller 6-1 is connected to the output end of the drive motor 4. Several receiving racks 6-2 are provided on the surface of the rotating roller 6-1. Grooves 6-3 are provided on the surface of the receiving racks 6-2. Several first buffer springs 6-4 are provided on the inner surface of the grooves 6-3. A buffer plate 6-5 is connected to the upper end of the first buffer springs 6-4.

[0040] In some examples, a preliminary buffer assembly 6 is designed to achieve the effect of buffering material reception. This assembly includes a rotating roller 6-1, which is rotatably connected inside the housing 1 and connected to the output end of the drive motor 4. When the drive motor 4 is running, it can drive the rotating roller 6-1 to rotate. Several receiving racks 6-2 are provided on the surface of the rotating roller 6-1. These receiving racks 6-2 are used to receive stones. Grooves 6-3 are opened on the surface of the receiving racks 6-2. Several first buffer springs 6-4 are installed on the inner surface of the grooves 6-3. The upper end of the first buffer springs 6-4 is connected to a buffer plate 6-5. When the stone falls onto the buffer plate 6-5 on the receiving rack 6-2, the buffer plate 6-5 will be compressed downward by the impact force of the material. The first buffer springs 6-4 absorb part of the impact force through their own elastic deformation, thereby slowing down the falling speed and impact force of the material, playing a preliminary buffering role. The amount of stone received each time is controlled by multiple receiving racks 6-2, and accumulation caused by continuous conveying can be avoided when putting it down.

[0041] like Figures 1-4 As shown, this embodiment proposes a secondary buffer assembly 7 including a movable bottom opening 7-1, which is located at the bottom of the outer shell 1. Connecting blocks 7-2 are provided on both lower ends of the outer shell 1. Connecting rods 7-3 are movably connected to the connecting blocks 7-2. A fixing block 7-4 is fixedly connected to one end of the connecting rod 7-3. A movable plate 7-5 is connected between the fixing blocks 7-4. A second spring 7-6 is fitted on the connecting rod 7-3. A second motor 7-7 is installed on the side surface of the outer shell 1. An extension plate 7-8 is provided on the side end face of the movable plate 7-5. A movable hole 7-9 is provided on the surface of the extension plate 7-8. An eccentric shaft bracket 7-10 is provided at the output end of the second motor 7-7. The lower end of the eccentric shaft bracket 7-10 is movably connected to the movable hole 7-9. A protrusion 7-11 is provided on the surface of the movable plate 7-5.

[0042] In some examples, to further enhance the cushioning effect on materials, a secondary cushioning component 7 is provided. This component includes a movable bottom opening 7-1 at the bottom of the outer shell 1, and connecting blocks 7-2 at the lower ends of both sides of the outer shell 1. A connecting rod 7-3 is movably fitted inside the connecting block 7-2. One end of the connecting rod 7-3 is fixedly connected to a fixing block 7-4. A movable plate 7-5 is connected between the two fixing blocks 7-4. In this way, the movable plate 7-5 can slide back and forth in the connecting block 7-2 via the connecting rod 7-3. A second spring 7-6 is also fitted on the connecting rod 7-3, and the second spring 7-6 provides elastic support for the movable plate 7-5. When the movable plate 7-5 is subjected to external force, it can buffer and rebound. A second motor 7-7 is installed on one side surface of the outer shell 1. An extension plate 7-8 is provided on the side end face of the movable plate 7-5. An movable hole 7-9 is opened on the surface of the extension plate 7-8. The lower end of the eccentric shaft bracket 7-10 at the output end of the second motor 7-7 is movably fitted into the movable hole 7-9. When the second motor 7-7 is running, the eccentric shaft bracket 7-10 will rotate with the motor. Due to the movable connection between the eccentric shaft bracket 7-10 and the movable hole 7-9, it will drive the extension plate 7-8, causing the movable plate 7-5 to reciprocate. Through the reciprocating motion, the stones will slowly roll downwards. The protrusion 7-11 provided on the surface of the movable plate 7-5 can further reduce the impact force of the rolling stones.

[0043] For example, such as Figure 1 As shown, baffles 8 are provided at both ends of the surface of the movable plate 7-5.

[0044] In some examples, a baffle 8 is provided to prevent particles from entering the gap between the movable plate 7-5 and the movable bottom opening 7-1 and causing wear.

[0045] For example, such as Figure 4 As shown, a rear groove 9 is provided at one end of the bottom of the outer shell 1, and the inner surface of the rear groove 9 is higher than the height of the raised layer 7-11.

[0046] In some examples, by providing a rear groove 9, the height of the protrusions 7-11 is avoided, thus preventing stones from getting stuck between the protrusions 7-11.

[0047] For example, such as Figure 3 As shown, the movable plate 7-5 is installed at an inclined angle, the raised layer 7-11 extends downward in a stepped shape, and the surface of the raised layer 7-11 is a planar structure.

[0048] In some examples, a stepped structure combined with a flat structure can reduce the speed at which stones roll downwards and allow them to be shaken out by reciprocating motion.

[0049] For example, such as Figure 2 As shown, the movable hole 7-9 has a transverse opening structure, and the eccentric shaft bracket 7-10 is slidably fitted to the inner wall of the movable hole 7-9.

[0050] In some examples, a stable reciprocating movement effect is achieved by using a transverse opening structure, with the opening length matching the eccentric distance of the eccentric shaft 7-10.

[0051] For example, such as Figure 3 As shown, the interior of the outer shell 1 has a circular structure.

[0052] In some examples, the interior is divided into two parts by a circular structure, combined with a continuously rotating roller 6-1 and multiple receiving racks 6-2, to avoid mutual interference.

[0053] In actual use: Install the device in a suitable position in the concrete mixing plant and connect the discharge hood 5. Turn on the drive motor 4 to drive the rotating roller 6-1 to rotate. The stones enter from the feed port 2 and fall onto the buffer plate 6-5 of the receiving frame 6-2. The buffer plate 6-5 is compressed by the impact and the first buffer spring 6-4 is used for initial buffering. The receiving frame 6-2, which is full of stones, rotates with the rotating roller 6-1 to the separation port 3. The stones fall and pass through the movable plate 7-5 of the secondary buffer component 7. At this time, the second motor 7-7 is turned on, and the eccentric shaft frame 7-10 drives the movable plate 7-5 to reciprocate. The convex layer 7-11 further slows down the rolling speed of the stones, and the stones are discharged through the discharge hood 5.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
