Description

Technical Field

[0001] This application relates to the field of concrete processing technology, specifically a ready-mixed concrete mixing device. Background Technology

[0002] Ready-mixed concrete is concrete that has been pre-mixed in a factory and then transported from the factory to the construction site by cement mixer trucks.

[0003] Chinese utility model patent CN222360415U discloses a pre-mixed concrete mixing device. It achieves uniform mixing of concrete through a transmission mechanism and a mixing mechanism, and uses an elastic ball to shake off the mixture from the mixer. However, a spring is installed on the top of the elastic ball to connect with a support plate. Over time, concrete can wrap around the outer wall of the spring. When the concrete solidifies, it affects the spring's contraction, preventing the elastic ball from returning to its initial position. When the mixer passes the initial position of the elastic ball again, it collides with the extended spring, causing the spring and mixer to become entangled, thus affecting the mixer's operation.

[0004] Therefore, this application provides a ready-mixed concrete mixing device to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a ready-mixed concrete mixing device, which aims to solve the problems mentioned in the background art, such as the elastic ball of the existing concrete mixer being connected to the support plate by a spring, resulting in concrete adhering to the outer wall of the spring after long-term use, causing problems with the spring's rebound, the elastic ball failing to return to its initial position, causing the mixer and spring to become entangled, and affecting the use of the mixer.

[0006] To achieve the above objectives, this application provides the following technical solution: a ready-mixed concrete mixing device, comprising a tank, a feed pipe fixedly installed on one side of the tank for feeding material into the tank, and a discharge pipe fixedly installed at the bottom of the tank for discharging material from the tank;

[0007] To facilitate the impact of the collision components on the mixing components: the tank body is equipped with a mixing component for concrete mixing, the top of the tank body is equipped with a drive component for driving the mixing component to rotate, the tank body is equipped with a support plate for the mixing component to mix at an angle, and the two ends of the support plate are symmetrically equipped with collision components for impacting the mixing component; the collision component includes a collision ball for impacting the mixing component, a return rod fixed to the top of the collision ball for returning the collision ball to center, a fixing bolt inserted inside the return rod for the return rod and the support plate to fit tightly, and a quick-release component between the fixing bolt and the return rod for moving the return rod. When the drive motor is started, the active gear drives the passive gear to rotate. The passive gear drives the mixing frame to mix the concrete inside the tank through the linkage rod. When the mixing frame rotates, it will impact the collision ball, causing the mixture adhering to the outer wall of the mixing frame to fall off. When the mixing frame moves away from the collision ball, the restoring force of the return rod will return the collision ball to its initial position. During this process, the return rod will not become entangled with the mixing frame, thus not affecting the use of the mixing frame. The length of the return rod is greater than the length of the quick-release component.

[0008] Preferably, to facilitate the installation of the collision assembly and the support plate: both ends of the support plate are fixedly connected to the two sides of the inner wall of the tank, and symmetrical through holes are provided at both ends of the support plate for the fixing bolts to pass through. A sealing ring is fitted on the outer wall of the top of the fixing bolt to seal between the through hole and the fixing bolt. The collision ball is installed at the bottom end of the support plate by connecting it to the quick-release component through the through hole. The collision assembly is installed at the bottom end of the support plate by fixing the support plate to the tank and then threading the fixing bolts to the connecting column.

[0009] Preferably, to facilitate the connection between the fixing bolt and the quick-connect component: the quick-connect component includes a connecting post inserted inside the return rod for connection with the fixing bolt, limiting blocks symmetrically fixed on both sides of the outer wall of the connecting post for engaging with the return rod, and locking blocks symmetrically fixed on both sides of the top of the connecting post for limiting the rotation of the connecting post. The bottom of the insertion hole has symmetrically formed limiting grooves on both sides for inserting the locking blocks, and the top of the connecting post has a threaded groove for threaded connection with the fixing bolt. By threading the fixing bolt into the threaded groove of the connecting post, the connecting post moves closer to the support plate. The engagement of the locking blocks with the limiting grooves restricts the rotation of the connecting post, thereby ensuring a tight fit between the top of the connecting post and the bottom of the support plate.

[0010] Preferably, to facilitate the installation of the quick-connect component and the return rod: the top end of the return rod has a slot for the connecting post to pass through, and the inner wall of the slot has symmetrical grooves for the insertion of the limiting block. By inserting the connecting post into the slot and connecting the limiting block with the groove, the return rod and the quick-connect component are quickly connected, and the return rod moves synchronously as the quick-connect component moves.

[0011] Preferably, for the installation between the mixing assembly and the support plate: the mixing assembly includes a mixing frame for mixing concrete, a driven gear disposed on the side of the drive assembly for meshing with the drive assembly, a linkage rod disposed between the mixing frame and the driven gear for linkage between the mixing frame and the driven gear, and a spherical support fixedly installed on the outside of the linkage rod for tilting the linkage rod. The support plate has a mounting groove in its center for installing the spherical support. By installing the spherical support in the mounting groove, the linkage rod connecting the mixing frame and the driven gear can rotate, allowing the mixing frame to be in an tilted state during the mixing process.

[0012] Preferably, to drive the rotation of the stirring assembly: the driving assembly includes a driving gear disposed inside the tank for meshing with the driven gear, and a drive motor disposed on the top of the driving gear for driving the driving gear to rotate. A circular hole is formed at the top of the tank, the output end of the drive motor is inserted into the circular hole, the bottom end of the drive motor is fixedly connected to the top of the tank, and the output end of the drive motor is fixedly connected to the top of the driving gear. The output end of the drive motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, thereby achieving stirring.

[0013] Preferably, to maintain the stability of the tank, a support frame is fitted around the outside of the tank to support it. The support frame keeps the tank in a vertical position, preventing it from tipping over.

[0014] This application, through the design of the mixing assembly, support plate, and collision assembly, connects the connecting column by inserting fixing bolts through the through holes in the support plate. The connecting column, through the limiting block, drives the return rod to fit tightly against the support plate, thus achieving the installation of the return rod and collision ball with the support plate. When the mixing frame impacts the collision ball, the return rod bends and deforms. When the mixing frame moves away from the collision ball, the return rod uses its own restoring force to return the collision ball to its initial position. At the same time, the bending of the return rod can prevent concrete from solidifying outside the return rod and will not entangle with the mixing frame, reducing the impact on the mixing operation of the mixing frame.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] This embodiment provides a pre-mixed concrete mixing device, such as... Figure 1-7 As shown, the stirring device includes a tank 1, a feed pipe 2 fixedly installed on one side of the tank 1 for feeding into the tank 1, and a discharge pipe 3 fixedly installed at the bottom of the tank 1 for discharging from the tank 1.

[0026] To facilitate the impact of the collision component 7 on the mixing component 4: the tank body 1 is equipped with a mixing component 4 for concrete mixing, the top of the tank body 1 is equipped with a drive component 5 for driving the mixing component 4 to rotate, the tank body 1 is equipped with a support plate 6 for the mixing component 4 to mix at an angle, and the two ends of the support plate 6 are symmetrically equipped with collision components 7 for impacting the mixing component 4; the collision component 7 includes a collision ball 71 for impacting the mixing component 4, a return rod 72 fixed to the top of the collision ball 71 for returning the collision ball 71 to center, a fixing bolt 73 inserted inside the return rod 72 for the return rod 72 and the support plate 6 to fit tightly together, and a quick-release component 74 set between the fixing bolt 73 and the return rod 72 for driving the return rod 72 to move. When the drive motor 52 is started, the active gear 51 drives the passive gear 42 to rotate. The passive gear 42 drives the mixing frame 41 to mix the concrete inside the tank 1 through the linkage rod 43. When the mixing frame 41 rotates, it will impact the collision ball 71, causing the mixture adhering to the outer wall of the mixing frame 41 to fall off. When the mixing frame 41 moves away from the collision ball 71, the restoring force of the return rod 72 will cause the collision ball 71 to return to its initial position. During this process, the return rod 72 will not become entangled with the mixing frame 41, so as not to affect the use of the mixing frame 41. The length of the return rod 72 is greater than the length of the quick-release part 74.

[0027] Specifically, to facilitate the installation of the collision assembly 7 and the support plate 6: both ends of the support plate 6 are fixedly connected to the two sides of the inner wall of the tank 1, and symmetrical through holes for the fixing bolts 73 are provided at both ends of the support plate 6. A sealing ring 75 is fitted on the outer wall of the top of the fixing bolt 73 to seal the through hole and the fixing bolt 73. The collision ball 71 is installed at the bottom of the support plate 6 by connecting it to the quick-connect piece 74 through the through hole. The collision assembly 71 is then installed at the bottom of the support plate 6 by fixing the support plate 6 to the tank 1 and then threading the fixing bolts 73 to the connecting column 741. The two ends of the support plate 6 are symmetrically provided with collision components 7, which are installed on the support plate 6 through the through holes. The sealing ring 75 is a rubber sealing ring. By rotating the fixing bolt 73, the fixing bolt 73 is connected to the thread groove of the connecting column 741, thereby squeezing the sealing ring 75 to seal the gap between the through hole and the fixing bolt 73 and prevent concrete from flowing in. The inner wall of the through hole is a smooth inner wall.

[0028] Furthermore, to facilitate the connection between the fixing bolt 73 and the quick-connect component 74: the quick-connect component 74 includes a connecting post 741 inserted inside the return rod 72 for connection with the fixing bolt 73, limiting blocks 742 symmetrically fixed on both sides of the outer wall of the connecting post 741 for engaging with the return rod 72, and locking blocks 743 symmetrically fixed on both sides of the top of the connecting post 741 for limiting the rotation of the connecting post 741. Restricting grooves for inserting the locking blocks 743 are symmetrically provided on both sides of the bottom end of the insertion hole, and a threaded groove for threaded connection with the fixing bolt 73 is provided on the top end of the connecting post 741. By threading the fixing bolt 73 into the threaded groove of the connecting post 741, the connecting post 741 moves closer to the support plate 6. Through the interlocking connection of the locking blocks 743 and the limiting grooves, the rotation of the connecting post 741 is limited, thereby ensuring that the top end of the connecting post 741 is tightly fitted against the bottom end of the support plate 6. The size of the connecting post 741 is larger than the size of the through hole. The part of the connecting post 741 that contacts the snap-fit ​​block 743 is welded and fixed. The size of the snap-fit ​​block 743 is adapted to the size of the limiting groove. The thread on the inner wall of the threaded groove meshes with the thread on the outer wall of the fixing bolt 73. Thus, when the fixing bolt 73 is rotated, the snap-fit ​​block 743 restricts the rotation of the connecting post 741, causing the connecting post 741 to move towards the support plate 6, and tightly fitting the top end of the connecting post 741 with the bottom end of the support plate 6. The part of the limiting block 742 that contacts the connecting post 741 is welded and fixed. The size of the limiting block 742 is adapted to the size of the internal slot of the return rod 72.

[0029] Furthermore, to facilitate the installation of the quick-connect component 74 and the return rod 72: the top of the return rod 72 has a slot for the connecting post 741 to pass through, and the inner wall of the slot has symmetrical slots for the retaining block 742 to pass through. By inserting the connecting post 741 into the slot and connecting the retaining block 742 with the slot, the return rod 72 and the quick-connect component 74 are quickly connected, and the return rod 72 moves synchronously as the quick-connect component 74 moves. The slot size is adapted to the size of the connecting post 741. The return rod 72 is made of elastic rubber, so that when installing the quick-release part 74 and the return rod 72, the connecting post 741 and the limiting block 742 can be inserted into the slot and the groove respectively by pulling the return rod 72. Under the rebound action of the return rod 72, the inner wall of the slot is tightly pressed against the outer wall of the connecting post 741. The collision ball 71 is a flexible sphere, so that it will not damage the mixing rack 41 when it impacts it. The collision ball 71 and the return rod The 72 components are fixed together by adhesive. The return rod 72 is cylindrical, so when the collision ball 71 is hit, the return rod 72 bends and deforms. When the mixing rack 41 moves away from the collision ball 71, it will drive the collision ball 71 back to its initial position. At the same time, when concrete is attached to the outer wall of the return rod 72, the return rod 72 will be repeatedly bent when it is repeatedly hit by the collision ball 71, which will prevent the concrete from solidifying on the outer wall of the return rod 72. Therefore, after long-term use, the return rod 72 will not affect the operation of the mixing rack 41.

[0030] Specifically, for the installation between the mixing assembly 4 and the support plate 6: the mixing assembly 4 includes a mixing frame 41 for mixing concrete, a driven gear 42 disposed on the side of the drive assembly 5 for meshing with the drive assembly 5, a linkage rod 43 disposed between the mixing frame 41 and the driven gear 42 for linkage between the mixing frame 41 and the driven gear 42, and a spherical support 44 fixedly installed on the outside of the linkage rod 43 for tilting the linkage rod 43. The support plate 6 has an installation groove in the middle for installing the spherical support 44. By installing the spherical support 44 in the installation groove, the linkage rod 43 connecting the mixing frame 41 and the driven gear 42 can rotate, allowing the mixing frame 41 to be in an tilted state during mixing. The size of the installation groove is adapted to the size of the spherical support 44. The linkage rod 43 is welded and fixed to the spherical support 44, and the top of the linkage rod 43 is welded and fixed to the contact part with the driven gear 42. The mixing frame 41 has four-sided blades, one side of which is parallel to the inner wall of the tank 1, so that the inner wall of the tank 1 can be cleaned when the mixing frame 41 rotates.

[0031] Specifically, to drive the rotation of the stirring assembly 4: the driving assembly 5 includes a driving gear 51 disposed inside the tank 1 for meshing with the driven gear 42, and a driving motor 52 disposed at the top of the driving gear 51 for driving the driving gear 51 to rotate. A circular hole is provided at the top of the tank 1, and the output end of the driving motor 52 is inserted into the circular hole. The bottom end of the driving motor 52 is fixedly connected to the top of the tank 1, and the output end of the driving motor 52 is fixedly connected to the top of the driving gear 51. The driving gear 51 is driven to rotate by the output end of the driving motor 52, which in turn drives the driven gear 42 to rotate, thereby achieving stirring. The driving motor 52 is electrically connected to an external control power supply. The output end of the driving motor 52 is fixedly connected to the top of the driving gear 51 by bolts. The driving gear 51 and the driven gear 42 mesh with each other, so that the rotation of the driving gear 51 drives the rotation of the driven gear 42, causing the driven gear 42 to always rotate around the outer wall of the driving gear 51, thereby causing the stirring frame 41 to tilt and rotate for stirring.

[0032] Specifically, to maintain the stability of tank 1, a support frame 8 is fitted around the outside of tank 1 to support it. The support frame 8 keeps tank 1 vertically positioned, preventing it from tipping over. The support frame 8 is a standard four-legged support frame, and the parts of the support frame 8 that contact the outer wall of tank 1 are welded and fixed, thus maintaining the stability of tank 1 during operation. A valve is installed at the discharge pipe 3 to control the discharge from tank 1. The feed pipe 2 is connected to the feed end via a flange, thus preventing dust generation during feeding.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
