Description

Technical Field

[0001] This utility model relates to the field of concrete crushing bin technology, specifically a crushing bin for concrete production. Background Technology

[0002] In the concrete production industry, crushed stone is a key raw material, and its storage and transportation efficiency directly affects the overall efficiency of the concrete production line. Currently, most crushed stone silos widely used in the market are designed directly at the top of the crusher. However, this traditional design of crushed stone silos has some significant shortcomings and limitations.

[0003] First, existing crushing silos generally employ a sloping design on one side, intended to guide the crushed stone towards the discharge port through gravity. However, during the high-speed pouring of crushed stone, the particles often directly impact the inner wall of the slope. This direct impact not only accelerates the wear of the inner wall but may also cause stone to fly due to the reaction force, increasing safety hazards at the production site. Second, existing crushing silos have limitations in discharge control. The discharge port size of most crushing silos is fixed, making it impossible to flexibly adjust the flow rate of crushed stone according to production needs. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of this utility model is to provide a crushed stone bin for concrete production, which solves the problems mentioned in the background above.

[0006] (II) Technical Solution

[0007] A crushed stone bin for concrete production includes a crusher body. A crushed stone bin body is installed at the top of the crusher body. An installation groove is formed on one side of the inner wall of the crushed stone bin body, and a sliding groove is formed on the outer surface of the other side of the crushed stone bin body. Multiple sets of second circular plates are fixedly installed on the outer surface of the installation groove, and a damper is installed on one side of the multiple sets of second circular plates. A first circular plate is connected to one side of the damper, and a buffer plate is connected to one side of the first circular plate. A spring is connected between the first circular plate and the second circular plate. The outer surface of the buffer plate is covered with rubber, and one end of the buffer plate is inclined.

[0008] Preferably, a shell is fixedly installed on one side of the crushed stone silo, and a sliding plate is movably installed on the inner wall of the shell, the sliding plate being movably installed in the inner wall of the chute.

[0009] Preferably, a support plate is fixedly installed at one end of the main body of the crusher, and two sets of cylinders are fixedly installed at the top of the support plate. One end of the two sets of cylinders is connected to a piston rod, and a limit block is fixedly installed at one end of the piston rod. A sliding plate is connected to the top of the limit block.

[0010] Preferably, a fixing rod is fixedly installed between the limiting blocks.

[0011] Preferably, a slot is provided on the top outer surface of the crusher body, and a card plate is movably installed on the inner wall of the slot, with the crushing chamber body fixedly installed on the top of the card plate.

[0012] Preferably, the card plate and the card slot are fixedly connected by multiple sets of bolts.

[0013] Preferably, a support rod is fixedly installed at the middle of the support plate, and a housing is fixedly installed at the top of the support rod.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. This utility model introduces a buffer plate with one end inclined and a rubber layer on its outer surface. This softens the contact between the crushed stone and the buffer plate as it enters the crushing bin, effectively reducing the direct impact of the crushed stone on the bin walls. This design avoids wear on the bin walls caused by high-speed impacts of the crushed stone, thus extending the service life of the crushing bin. Furthermore, when the crushed stone impacts the buffer plate, the buffer plate elastically buffers and absorbs energy through the springs and dampers behind it. This process not only reduces the impact force of the crushed stone on the bin walls but also significantly reduces the resulting noise and vibration.

[0016] 2. This utility model uses a cylinder to drive a piston rod and a limiting block, which in turn moves a sliding plate back and forth in a chute, enabling flexible adjustment of the discharge port size of the crushed stone silo. This design meets the needs of different production stages for crushed stone flow rate, improving production efficiency and flexibility. Attached Figure Description

Detailed Implementation

[0024] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0025] Please see Figure 1-6 One embodiment provided by this utility model:

[0026] A crushing bin for concrete production includes a crusher body 1, a crushing bin body 2 installed at the top of the crusher body 1, an installation groove 8 on one side of the inner wall of the crushing bin body 2, and a sliding groove 9 on the outer surface of the other side of the crushing bin body 2. Multiple sets of second circular plates 314 are fixedly installed on the outer surface of the installation groove 8, and a damper 312 is installed on one side of the multiple sets of second circular plates 314. A first circular plate 311 is connected to one side of the damper 312, and a buffer plate 3 is connected to one side of the first circular plate 311. A spring 313 is connected between the first circular plate 311 and the second circular plates 314. The outer surface of the buffer plate 3 is covered with rubber, and one end of the buffer plate 3 is inclined.

[0027] Furthermore, a shell 5 is fixedly installed on one side of the crushing chamber 2, and a sliding plate 511 is movably installed on the inner wall of the shell 5. The sliding plate 511 is movably installed in the inner wall of the chute 9. A support plate 6 is fixedly installed at one end of the crusher body 1, and two sets of cylinders 7 are fixedly installed at the top of the support plate 6. A piston rod 711 is connected to one end of the two sets of cylinders 7, and a limit block 512 is fixedly installed at one end of the piston rod 711. The sliding plate 511 is connected to the top of the limit block 512. By driving the cylinder 7, the piston rod 711 can retract, thereby driving the sliding plate 511 to move synchronously. The sliding plate 511 can move along the chute 9 in the inner wall of the shell 5, thereby adjusting the size of the discharge port. The shell 5 also serves as a protective function.

[0028] Furthermore, a fixing rod 513 is fixedly installed between the limiting blocks 512. The fixing rod 513 firmly connects the two limiting blocks 512 together, forming a stable structure. This effectively prevents the limiting blocks 512 from shifting or shaking during the movement of the piston rod 711 driven by the cylinder 7, thereby ensuring that the sliding plate 511 moves smoothly and accurately within the slide groove 9.

[0029] Furthermore, a slot 111 is provided on the top outer surface of the crusher body 1, and a card plate 211 is movably installed on the inner wall of the slot 111. The top of the card plate 211 is fixedly installed on the crushing chamber 2. The matching design of the card plate 211 and the slot 111 ensures a stable connection between the crushing chamber 2 and the crusher body 1.

[0030] Furthermore, the card plate 211 and the card slot 111 are fixedly connected by multiple sets of bolts 4. The addition of multiple sets of bolts 4 significantly enhances the connection stability between the card plate 211 and the card slot 111, ensuring that the crushed stone bin 2 will not loosen or fall off when subjected to external forces such as vibration and impact, thereby ensuring the stable operation of the production line.

[0031] Furthermore, a support rod 611 is fixedly installed at the middle of the support plate 6, and a housing 5 is fixedly installed at the top of the support rod 611. As a key component connecting the support plate 6 and the housing 5, the support rod 611 plays a role in strengthening the overall structural stability, making the housing 5 more robust.

[0032] Working principle: First, the crushed stone is fed into the crushed stone silo 2 through an external conveying device. During the process of the crushed stone entering, due to the inclined buffer plate 3 at one end and the rubber layer wrapped on the outer surface of the buffer plate 3, the contact between the crushed stone and the buffer plate 3 becomes gentle, effectively reducing the direct impact of the crushed stone on the inner wall of the crushed stone silo 2.

[0033] When crushed stone impacts the buffer plate 3, the buffer plate 3, through the action of the spring 313 between the first circular plate 311 and the second circular plate 314 and the damper 312, elastically buffers and absorbs energy, further reducing the impact of crushed stone on the silo wall, extending the service life of the crushed stone silo, and reducing noise and vibration.

[0034] The size of the discharge port of the crushed stone silo 2 is adjusted by the cylinder 7. The cylinder 7 is fixedly mounted on the support plate 6, and the piston rod 711 connected to one end of the cylinder 7 can extend and retract under the drive of the cylinder 7. The other end of the piston rod 711 is fixedly mounted with a limit block 512, which cooperates with the sliding groove 9 on the inner wall of the outer shell 5 through the sliding plate 511, so as to realize the back-and-forth movement of the sliding plate 511. As the adjusting component of the discharge port, the position change of the sliding plate 511 directly determines the size of the discharge port.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
