Description

Technical Field

[0001] This utility model relates to the field of concrete preparation technology, specifically to a renewable crack-resistant concrete mixing equipment. Background Technology

[0002] Concrete is an indispensable basic material in various construction projects, with a massive amount of concrete being used in the construction of buildings and building components every year. However, traditional concrete has some limitations in practical applications, especially in terms of crack resistance. Against this backdrop, crack-resistant recycled concrete has emerged. As a type of recycled concrete with crack-resistant properties, it brings new solutions and development directions to the field of building materials.

[0003] Extensive research revealed CN212819551U, which discloses an aggregate mixing device for preparing crack-resistant recycled concrete. The device includes a mixing tank and a base. Support legs are fixedly installed at the bottom of the mixing tank and are connected to the top of the base via these legs. Feed inlets are fixedly installed on the top of both sides of the mixing tank. A cover plate is installed on the top of the mixing tank, and a drive assembly is installed on the top of the cover plate. A mixing assembly is installed inside the mixing tank. In this prior art device, a drive motor rotates the mixing assembly, using mixing blades and rollers to initially increase the mixing amplitude. A servo motor then drives a threaded rod to rotate, causing a second support plate to move up and down with the drive motor. The mixing assembly moves up and down synchronously while rotating, further increasing the mixing amplitude and thus improving the mixing effect.

[0004] However, in the existing technology, when the device is in use, especially during the discharge process, the high viscosity of the renewable crack-resistant concrete leads to poor discharge. Therefore, a renewable crack-resistant concrete mixing device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a renewable crack-resistant concrete mixing equipment, which has the advantages of effectively improving the problem of poor material discharge and enabling high-viscosity renewable crack-resistant concrete to be discharged smoothly. It solves the problem of poor material discharge caused by the high viscosity of renewable crack-resistant concrete in the existing mixing equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a renewable crack-resistant concrete mixing equipment, comprising a mixing silo and a base frame. The bottom of the mixing silo has a trapezoidal open base with reinforcing ribs welded to it, and the base is movably connected to the base frame via a slide rail guide groove. Connecting frames are installed at the four corners of the base frame via damping spring buffers, and the connecting frames are fixedly connected to the bottom of the base. A rectangular reserved groove is opened at the bottom of the side wall of the mixing silo, and a top slide is fixed above the reserved groove by an angle steel bracket. A discharge baffle with a guide flange is slidably installed between the top slide and the base. Vibration motors with vibration isolation rubber layers are symmetrically installed at the bottom of the base. An embedded polyurethane sealing strip is provided at the edge of the reserved groove. A mixing assembly is installed on the top of the mixing silo.

[0007] Preferably, the inner surface of the discharge baffle is an arc-shaped surface that matches the curvature of the outer wall of the mixing hopper, and its surface is coated with a wear-resistant polytetrafluoroethylene coating by plasma spraying, with an arc-shaped handle with anti-slip texture welded on the front.

[0008] In the design, a discharge baffle with an inner surface that matches the curvature of the outer wall of the mixing hopper is set, and a polytetrafluoroethylene wear-resistant coating is formed on its surface by plasma spraying. An arc-shaped handle with anti-slip texture is welded on the front, so that the discharge baffle fits tightly with the mixing hopper, reducing the risk of material leakage. The wear-resistant coating extends the service life, and the arc-shaped handle with anti-slip texture facilitates operation.

[0009] Preferably, the vibration isolation rubber layer of the vibration motor has staggered grooves on its surface, and the vibration motor and the base are rigidly connected by high-strength bolts.

[0010] In the design, by setting the vibration isolation rubber layer of the vibratory motor with interlaced grooves and using high-strength bolts to rigidly connect it to the base, the vibratory motor can effectively buffer its own vibration during operation, reduce the impact on the overall structure of the equipment, and at the same time ensure a stable connection and guarantee the vibration effect.

[0011] Preferably, the polyurethane sealing strip at the edge of the reserved groove has a rectangular cross-section structure and is continuously arranged along the edge of the reserved groove to form a closed ring. The polyurethane sealing strip and the discharge baffle are in an interference fit.

[0012] In the design, by setting the edge of the reserved groove to a rectangular cross-section structure, and continuously arranging polyurethane sealing strips along the edge to form a closed ring and having an interference fit with the discharge baffle, the sealing performance of the discharge baffle is improved when it is closed, thus preventing material leakage from gaps during the mixing process.

[0013] Preferably, the mixing assembly includes a top frame fixed to the top of the mixing hopper, feeding flaps hinged to both sides of the top frame, a drive motor mounted at the central rear end of the top frame via a coupling, the output shaft of the drive motor connected to a cross-shaped mixing frame, and a polyurethane scraper with gradually decreasing thickness mounted at the end of the mixing frame via a snap fastener.

[0014] In the design, a top frame is fixed to the top of the mixing silo, with feeding flaps hinged on both sides, and a drive motor is installed at the central rear end via a coupling. The output shaft of the drive motor is connected to a cross-shaped mixing frame, and a polyurethane scraper with gradually decreasing thickness is installed at the end of the cross-shaped mixing frame via a snap-fit. This makes feeding convenient, allows for all-round mixing of materials during mixing, and the polyurethane scraper can effectively scrape materials off the silo wall, improving the uniformity of mixing.

[0015] Preferably, the drive motor is equipped with a forward and reverse rotation control module, which integrates a non-contact position sensor. The detection end of the non-contact position sensor is mechanically linked to the slider assembly of the discharge baffle through a universal joint linkage rod, and the movement trajectory of the linkage rod matches the opening and closing stroke of the discharge baffle.

[0016] In the design, by configuring a forward and reverse control module for the drive motor and integrating a non-contact position sensor, the detection end of the drive motor is mechanically linked to the slider assembly of the discharge baffle through a universal joint linkage rod. This matches the movement trajectory of the linkage rod with the opening and closing stroke of the discharge baffle, enabling the drive motor to automatically adjust its direction according to the discharge situation, thereby achieving intelligent control and improving the coordination efficiency of mixing and discharging.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention achieves the effect of opening a rectangular reserved groove at the bottom of the side wall of the mixing silo, fixing the top slide with an angle steel bracket and installing a discharge baffle with a guide flange, and setting an embedded polyurethane sealing strip at the edge of the reserved groove. This allows the discharge baffle to slide open and close flexibly, and provides good sealing during the mixing and discharge process, ensuring the smooth progress of the discharge process.

[0019] This invention achieves the effect of transmitting the vibration generated by the vibration motor to the mixing silo during operation by symmetrically installing a vibration motor with a vibration isolation rubber layer at the bottom of the base. This enhances the fluidity of the renewable crack-resistant concrete in the silo, improves the problem of poor material discharge, and at the same time reduces the adverse effects of vibration on the overall structure of the equipment, ensuring the stable operation of the equipment.

[0020] This invention achieves the effect of the mixing silo by welding a trapezoidal open base with reinforcing ribs to the bottom of the mixing silo, which is movably connected to the base frame via a slide rail guide groove. Damping spring buffers are installed at the four corners of the base frame and fixed to the bottom of the base. This allows the mixing silo to move slightly on the slide rail guide groove when the vibration motor is working. Combined with the buffering effect of the damping spring buffers, the vibration effect on the material is enhanced to promote the material discharge, while protecting the equipment structure from excessive vibration damage.

[0021] This invention achieves the effect of fully stirring the materials during the mixing process by installing a mixing component on the top of the mixing silo, so that the materials are mixed evenly and avoids the effect of excessive local viscosity due to uneven mixing, which affects the discharge of materials, thus providing a good material foundation for smooth discharge.

[0027] 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.

[0028] Example 1

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, one embodiment of this utility model provides a renewable crack-resistant concrete mixing device, including a mixing silo 3 and a base frame 1. The bottom of the mixing silo 3 has a trapezoidal open base 34 with reinforcing ribs welded on it. The base 34 is movably connected to the base frame 1 through a slide rail guide groove. Connecting frames 12 are installed at the four corners of the base frame 1 via damping spring buffers 11. The connecting frames 12 are fixedly connected to the bottom of the base 34. A rectangular reserved groove 32 is opened at the bottom of the side wall of the mixing silo 3. A top slide 31 is fixed above the reserved groove 32 by an angle steel bracket. A discharge baffle 2 with a guide flange is slidably installed between the top slide 31 and the base 34. Vibration motors 33 with vibration isolation rubber layers are symmetrically installed at the bottom of the base 34. An embedded polyurethane sealing strip is provided at the edge of the reserved groove 32. A mixing component 4 is installed on the top of the mixing silo 3.

[0030] Specifically, by opening a rectangular reserved groove 32 at the bottom of the side wall of the mixing silo 3, fixing the top slide 31 with an angle steel bracket and installing a discharge baffle 2 with a guide flange, and setting an embedded polyurethane sealing strip at the edge of the reserved groove 32, the discharge baffle 2 can be flexibly opened and closed, and has good sealing performance during the mixing and discharge process, ensuring the smooth progress of the discharge process.

[0031] By symmetrically installing a vibration motor 33 with a vibration isolation rubber layer at the bottom of the base 34, the vibration generated by the vibration motor 33 during operation is transmitted to the mixing silo 3, which enhances the fluidity of the renewable crack-resistant concrete in the silo and improves the problem of poor material discharge. At the same time, the vibration isolation rubber layer reduces the adverse effects of vibration on the overall structure of the equipment and ensures the stable operation of the equipment.

[0032] By welding a trapezoidal open base 34 with reinforcing ribs to the bottom of the mixing silo 3, and movably connecting it to the base frame 1 via a slide rail guide groove, and fixing the connecting brackets 12 at the four corners of the base frame 1 to the bottom of the base 34 via damping spring buffers 11, the mixing silo 3 can move slightly on the slide rail guide groove when the vibration motor 33 is working. With the buffering effect of the damping spring buffers 11, the vibration effect on the material is enhanced to promote the discharge of the material, while protecting the equipment structure from excessive vibration damage.

[0033] By installing the mixing component 4 on the top of the mixing hopper 3, the material is fully stirred during the mixing process, ensuring uniform mixing and avoiding excessive local viscosity due to uneven mixing, which affects material discharge and provides a good material foundation for smooth material discharge.

[0034] Example 2

[0035] To further optimize the discharge structure, improve equipment stability and sealing, and ensure efficient mixing and smooth discharge of renewable crack-resistant concrete, such as... Figure 1 and Figure 3As shown, in this embodiment, the inner surface of the discharge baffle 2 is an arc-shaped surface that matches the curvature of the outer wall of the mixing bin 3. Its surface is coated with a wear-resistant polytetrafluoroethylene coating by plasma spraying, and an arc-shaped handle 21 with anti-slip texture is welded on the front.

[0036] In the design, a discharge baffle 2 with an inner surface that matches the curvature of the outer wall of the mixing chamber 3 is set, and a polytetrafluoroethylene wear-resistant coating is formed on its surface by plasma spraying. An arc-shaped handle 21 with anti-slip texture is welded on the front, so that the discharge baffle 2 fits tightly with the mixing chamber 3, reducing the risk of material leakage, extending the service life of the wear-resistant coating, and facilitating operation with the arc-shaped handle 21 with anti-slip texture.

[0037] Furthermore, the vibration isolation rubber layer of the vibration motor 33 has interlaced grooves on its surface, and the vibration motor 33 and the base 34 are rigidly connected by high-strength bolts.

[0038] In the design, by setting the groove pattern of the vibration isolation rubber layer of the vibration motor 33 to be distributed in an alternating manner, and using high-strength bolts to rigidly connect it to the base 34, the vibration motor 33 can effectively buffer its own vibration when working, reduce the impact on the overall structure of the equipment, and at the same time ensure a stable connection and guarantee the vibration effect.

[0039] Furthermore, the polyurethane sealing strip at the edge of the reserved groove 32 has a rectangular cross-section structure and is continuously arranged along the edge of the reserved groove 32 to form a closed ring. The polyurethane sealing strip and the discharge baffle 2 are in an interference fit.

[0040] In the design, by setting the edge of the reserved groove 32 to be a rectangular cross-section structure, and continuously arranging a closed ring along the edge with a polyurethane sealing strip that has an interference fit with the contact surface of the discharge baffle 2, the sealing performance of the discharge baffle 2 is better when it is closed, thus preventing material leakage from the gaps during the mixing process.

[0041] Example 3

[0042] To achieve efficient mixing, intelligent control of the mixing and discharging process, and to improve the overall automation level and collaborative operation efficiency of the mixing equipment, such as... Figure 1 and Figure 4 As shown, in this embodiment, the mixing assembly 4 includes a top frame 41 fixed to the top of the mixing hopper 3, feeding flaps 42 are hinged to both sides of the top frame 41, and a drive motor 43 is installed at the central rear end of the top frame 41 through a coupling. The output shaft of the drive motor 43 is connected to a cross-shaped mixing frame 44, and a polyurethane scraper with gradually decreasing thickness is installed at the end of the mixing frame 44 through a snap fastener.

[0043] In the design, a top frame 41 is fixed to the top of the mixing silo 3, with feeding flaps 42 hinged on both sides, and a drive motor 43 is installed at the central rear end via a coupling. The output shaft of the drive motor 43 is connected to a cross-shaped mixing frame 44. A polyurethane scraper with gradually decreasing thickness is installed at the end of the cross-shaped mixing frame 44 via a snap-fit, which makes feeding convenient and allows for all-round mixing of materials. The polyurethane scraper can effectively scrape materials off the silo wall, improving the uniformity of mixing.

[0044] Furthermore, the drive motor 43 is equipped with a forward and reverse rotation control module. The forward and reverse rotation control module integrates a non-contact position sensor. The detection end of the non-contact position sensor forms a mechanical linkage with the slider assembly of the discharge baffle 2 through a universal joint linkage rod. The movement trajectory of the linkage rod matches the opening and closing stroke of the discharge baffle 2.

[0045] In the design, by configuring a forward and reverse control module for the drive motor 43 and integrating a non-contact position sensor, its detection end forms a mechanical linkage with the slider assembly of the discharge baffle 2 through the universal joint linkage rod, matching the movement trajectory of the linkage rod with the opening and closing stroke of the discharge baffle 2, thereby enabling the drive motor 43 to automatically adjust its direction according to the discharge situation, realizing intelligent control and improving the coordination efficiency of mixing and discharging.

[0046] When using this invention, check whether all components of the equipment are securely connected, and whether the damping spring buffer 11, vibration motor 33, high-strength bolts, etc., are in good working order. Ensure that the discharge baffle 2 is in the closed state and the embedded polyurethane sealing strip is tightly fitted to prevent material leakage. Place the raw materials to be mixed into the mixing hopper 3 through the feeding flap 42.

[0047] The mixing assembly 4 is activated, and the drive motor 43 rotates the cross-shaped mixing frame 44. The polyurethane scraper scrapes the material from the bin wall to ensure thorough mixing. During the mixing process, the direction of the drive motor 43 can be adjusted via the forward and reverse control module to ensure more uniform mixing of the materials.

[0048] After mixing is complete, operate the arc-shaped handle 21 to push the discharge baffle 2 open along the guide rail. At the same time, the non-contact position sensor detects the movement of the discharge baffle 2 and triggers the vibration motor 33 to start, using its vibration to assist in the discharge, allowing the high-viscosity, crack-resistant renewable concrete to be discharged smoothly. After discharge is complete, close the discharge baffle 2 to prepare for the next mixing operation.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
