Description

Technical Field

[0001] This application relates to the field of concrete mixing equipment, and in particular to a horizontal concrete mixer. Background Technology

[0002] Horizontal concrete mixers are indispensable equipment in construction, widely used for mixing and preparing concrete. As construction projects increasingly demand higher concrete quality, mixer designs are constantly being optimized to meet the needs of efficient and precise construction. Traditional horizontal concrete mixers achieve material mixing and discharge through a rotating drum, offering significant advantages in concrete mixing efficiency and discharge control, greatly improving material utilization and operational efficiency during construction.

[0003] Currently, horizontal concrete mixers commonly suffer from the problem of inaccurate control over the discharge rate during the discharge process. Due to the lack of effective angle positioning and limiting measures, the drum is prone to unintended tilting under gravity, making it difficult to stably control the discharge rate and affecting construction quality and efficiency. In addition, traditional discharge control methods lack flexibility and are difficult to adapt to diverse construction needs. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a horizontal concrete mixer.

[0005] A horizontal concrete mixer, comprising: A frame includes a base and a support frame, the support frame being fixed to the upper surface of the base, and the upper surface of the base bearing a tilting gear; The outer casing is cylindrical and mounted on the support frame. One end of the outer casing is fixed with a tilting gear ring that meshes with the tilting gear. The top of the outer casing has a feeding port. A stirring device includes a housing and a stirring shaft passing through the housing, the housing controlling the rotation of the stirring shaft and a tilting gear. By adopting the above solution, the tilt angle of the outer shell can be controlled by the cooperation of the tilting gear and the tilting ring, and can be limited to this tilt angle. This allows for stable control of the material output of the outer shell, preventing the outer shell from tilting arbitrarily due to the gravity of the material inside, which would result in inaccurate material output.

[0006] In one embodiment, a baffle plate is provided at the bottom of the feeding port. The baffle plate can slide along the inner wall of the outer shell with the axis of the outer shell as the center. When the baffle plate is opposite to the feeding port, the baffle plate blocks the feeding port.

[0007] By adopting the above scheme, when the mixer discharges material through the feeding port, the baffle plate can slide at different angles along the inner wall of the outer shell to control the size of the feeding port. The operator can control the discharge amount by controlling the size of the feeding port. When the baffle plate is facing the feeding port, the baffle plate can block the feeding port, thereby sealing the outer shell.

[0008] In one embodiment, the inner wall surface of the housing is provided with a material-blocking sliding groove, the material-blocking sliding groove extends along the rotation direction of the housing, and one side of the material-blocking plate cooperates with the material-blocking sliding groove.

[0009] By adopting the above scheme, when the material is being stirred and poured, the shape formed by the baffle plate and the feeding port is a rectangle extending in the vertical direction. The mixer needs to rotate at a larger angle to pour the material more effectively. With the design of the baffle sliding groove, when the baffle plate is sliding, the shape of the feeding port is a rectangle extending in the horizontal direction, resulting in higher discharge efficiency.

[0010] In one embodiment, the inner wall of the feeding port extends away from the outer shell to form a feeding flange, the side of the feeding flange is provided with a guide groove, and the side of the baffle plate away from the baffle sliding groove is provided with a guide shaft that cooperates with the guide groove.

[0011] By adopting the above solution, staff can manually operate the guide shaft to slide within the wire groove, thereby controlling the opening size of the feeding port.

[0012] In one embodiment, the guide shaft has guide grooves at both ends, and the guide shaft can slide in a direction perpendicular to the guide grooves. The end of the guide shaft near the tilting gear ring can cooperate with the tilting gear ring.

[0013] By adopting the above scheme, the tilting gear ring can limit the guide shaft, thereby allowing the opening of the feeding port to maintain a fixed size.

[0014] In one embodiment, a filter screen is provided on the side of the guide shaft away from the baffle plate, and a filter sliding groove that cooperates with the filter screen is also provided on the inner wall of the outer shell. A slag discharge port is provided on the side wall of the feeding flange in the direction of movement of the filter screen.

[0015] By adopting the above scheme, when the baffle plate controls the feeding port to be in the open state, the filter screen can filter out large particles of impurities when feeding materials. When the sliding guide shaft closes the feeding port, the large particles of filter residue intercepted by the filter screen are discharged from the slag discharge port.

[0016] In one embodiment, a partition is provided between the filter screen and the baffle plate, and the guide shaft passes through the partition in the direction of the partition's extension.

[0017] By adopting the above solution, the baffle can separate the filter screen from the baffle plate, so that the filter residue will not move to the baffle plate, and the large particles of filter residue intercepted will not be discharged from the slag discharge port.

[0018] In one embodiment, the filter screen includes a mounting frame and a filter screen body, the filter screen body being located within the mounting frame and detachably connected to the mounting frame.

[0019] By adopting the above solution, the filter screen can be replaced with different models of filter screen body, thereby enabling the filter screen body to meet different filtration needs.

[0020] In one embodiment, the mounting frame is provided with slide rails on both sides that cooperate with the filter sliding groove. The slide rails are provided with elastic actuating members that are integral with the filter body. The filter sliding groove is provided with actuating protrusions that cooperate with the elastic actuating members.

[0021] By adopting the above scheme, during the sliding process of the filter screen, the elastic actuating component comes into contact with the actuating protrusion. The actuating protrusion forces the elastic actuating component to deform. When the elastic actuating component passes the actuating protrusion, the elastic actuating component rebounds and generates vibration. The elastic actuating component transmits the vibration to the surface of the filter screen body, thereby shaking up the filter residue and preventing the filter residue from adhering to the surface of the filter screen and being unable to be discharged smoothly from the slag discharge port.

[0022] In one embodiment, stirring blades are distributed on the outer peripheral surface of the stirring shaft. The stirring blades are strip-shaped and have a scraper that contacts the inner wall of the outer shell on the side facing the inner wall. The scraper is made of flexible material.

[0023] By adopting the above solution, since the material being mixed in the horizontal concrete mixer is sticky, it will stick to the inner wall of the outer shell. By setting the scraper, the mixing blade can scrape off the material remaining on the inner wall of the outer shell during the mixing process. Setting the scraper to a flexible material can avoid the scraper scratching the inner wall of the outer shell, and at the same time prevent the scraper from interfering with the inner wall of the outer shell, which would affect the rotation of the mixing blade.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a tilting gear ring at one end of the outer shell, the cooperation between the tilting gear and the tilting gear ring can control the tilt angle of the outer shell and limit it to this tilt angle. This allows for stable control of the material output of the outer shell and prevents the outer shell from tilting arbitrarily due to the gravity of the material inside, which would result in inaccurate material output.

[0025] 2. By setting up the baffle plate, when the mixer discharges material through the feeding port, the baffle plate can slide at different angles along the inner wall of the outer shell to control the size of the feeding port. The operator can control the discharge amount by controlling the size of the feeding port. When the baffle plate is directly facing the feeding port, the baffle plate can block the feeding port, thereby closing the outer shell. The operator can control the guide shaft to cooperate with the tilting toothed ring so that the opening of the feeding port can be kept at a fixed size.

[0026] 3. Because the material being mixed in a horizontal concrete mixer is sticky, it will stick to the inner wall of the outer shell. By setting the scraper, the mixing blades can scrape off the material remaining on the inner wall of the outer shell during the mixing process. Setting the scraper to a flexible material can prevent the scraper from scratching the inner wall of the outer shell, and at the same time prevent the scraper from interfering with the inner wall of the outer shell, which would affect the rotation of the mixing blades.

Detailed Implementation

[0035] Therefore, it is necessary to provide a horizontal concrete mixer that can stably control the tilt angle to achieve precise pouring.

[0036] Please see Figure 1-4 , Figure 1 This application provides a structural schematic diagram of a horizontal concrete mixer, including a frame 1, a housing 2, and a mixing device 3. The frame 1 consists of a base 11 and a support frame 12. The support frame 12 is fixed to the upper surface of the base 11, and a tilting gear 111 is provided on the upper surface of the base 11. The housing 2 is cylindrical and mounted on the support frame 12. One end is provided with a tilting gear ring 21 that cooperates with the tilting gear 111. The top of the housing 2 has a feeding port 22. The inner wall of the feeding port 22 extends away from the housing 2 to form a feeding flange 221. Workers can feed and discharge materials through the feeding port 22. The mixing device 3 includes a housing 31 and a mixing shaft 32 passing through the housing 2. Mixing blades 321 are distributed around the outer periphery of the mixing shaft 32. The mixing blades 321 are strip-shaped and can... To amplify the material mixing area, a scraper 3211 is provided on the side of the mixing blade 321 facing the inner wall of the outer shell 2. The scraper 3211 contacts the inner wall of the outer shell 2. When the mixing shaft 32 drives the mixing blade 321 to rotate, the scraper 3211 can scrape off the material remaining on the inner wall of the outer shell 2. The scraper 3211 can be made of flexible materials such as rubber and polyurethane to avoid scratching the inner wall of the outer shell 2 and to prevent interference between the scraper 3211 and the inner wall of the outer shell 2, which would affect the rotation of the mixing blade 321.

[0037] During use, the operator controls the rotation of the stirring shaft 32 through the housing 31 to stir the material. When pouring the material, the operator controls the rotation of the tilting gear 111 through the housing 31. The tilting gear 111 engages with the tilting gear 111 to tilt the outer shell 2. When the outer shell 2 tilts to the optimal tilting angle, the operator stops the rotation of the tilting gear 111 by operating the housing 31, so that the outer shell 2 maintains a fixed tilting angle, which makes it easy for the operator to control the discharge amount of the outer shell 2.

[0038] The frame 1 includes a base 11 and a support frame 12. The base 11 supports the entire device, and the support frame 12 is fixed to the upper surface of the base 11, serving to support the outer shell 2. The tilting gear 111 can be a spur gear or a helical gear, which cooperates with the tilting gear ring 21 to achieve the rotational positioning of the outer shell 2. The tilting gear ring 21 protrudes from the outer circumference of the outer shell 2 and can be made of high-strength alloy steel or wear-resistant plastic to improve durability. The feeding port 22 at the top of the outer shell 2 can be implemented in various ways, such as a circular or elliptical opening. In this application, the feeding port 22 is rectangular, and a baffle plate 23 is provided at the bottom of the feeding port 22. The inner wall of the outer shell 2 is provided with a material-blocking sliding groove 24 that cooperates with the baffle plate 23, so that the baffle plate 23 can slide along the inner wall of the outer shell 2. When the baffle plate 23 is opposite to the feeding port 22, it blocks the feeding port 22, and the feeding port 22 is in a closed state. The specific structure of the baffle plate 23 can be a metal plate or a composite material plate, and the surface can be coated with an anti-stick coating to reduce material adhesion.

[0039] The material-stopping sliding groove 24 extends along the rotation direction of the outer shell 2 to ensure the stability of the movement trajectory of the material-stopping plate 23. One side of the material-stopping plate 23 cooperates with the material-stopping sliding groove 24, and the other side is provided with a guide shaft 25. The two ends of the guide shaft 25 are respectively inserted into the guide grooves 2211 formed by the inner wall of the feeding flange 221. The guide shaft 25 can slide in a direction perpendicular to the guide grooves 2211, and the end near the tilting toothed ring 21 can cooperate with the tilting toothed ring 21 to play a limiting role. The guide shaft 25 adopts a double rod structure, with both ends embedded in the guide grooves 2211 and the middle part connected to the material-stopping plate 23. The guide shaft 25 can be made of stainless steel or aluminum alloy, and the surface is polished to reduce friction. In actual use, the staff first slides the baffle plate 23 to adjust the opening size of the feeding port 22. After the staff confirms the opening size, they slide the guide shaft 25 so that one end of the guide shaft 25 close to the tilting gear ring 21 cooperates with the tilting gear ring 21. The guide shaft 25 is locked between two adjacent gear teeth of the tilting gear ring 21 and is thus limited. The baffle plate 23 is also limited, so that the opening size of the feeding port 22 remains unchanged.

[0040] A filter screen 26 is installed on the side of the guide shaft 25 away from the baffle plate 23. A filter sliding groove 27 that mates with the filter screen 26 is provided on the inner wall of the outer casing 2. A slag discharge port 2212 is provided on the side wall of the feeding flange 221 in the direction of movement of the filter screen 26. A partition is provided between the filter screen 26 and the baffle plate 23. The guide shaft 25 passes through the partition along the extension direction of the partition. When the operator slides the filter screen 26 toward the slag discharge port 2212, the partition prevents the filter slag separated by the filter screen from moving toward the baffle plate 23. When the filter screen 26 slides to the end, the partition abuts against the inner wall of the feeding flange 221, thereby ensuring that the filter slag is fully discharged.

[0041] Please refer to the following: Figure 6-7 , Figure 6This diagram illustrates the connection between the baffle plate and the filter screen. The filter screen 26 consists of a mounting frame 261 and a filter screen body 262. The filter screen body 262 is located within and detachably connected to the mounting frame 261. A snap-fit ​​structure can be provided within the mounting frame 261, and the edge of the filter screen body 262 has grooves that engage with the snap-fit, allowing for quick assembly and disassembly via pressing. The mounting frame 261 can also be designed with grooves to accommodate the filter screen body 262 and the elastic actuating element 2631, allowing the filter screen body 262 to be directly pressed into the mounting frame 261. Slide rails 263 are provided on both sides of the mounting frame 261, and these slide rails 263 engage with the filter sliding groove 27 to ensure smooth movement of the filter screen 26. The slide rail 263 is provided with an elastic actuating element 2631, and the filter sliding groove 27 is provided with an actuating protrusion 271. When the filter screen 26 slides, the elastic actuating element 2631 contacts the actuating protrusion 271 to generate vibration, thereby shaking the filter residue and preventing it from adhering to the surface of the filter screen. The edge of the filter screen body 262 can be welded to the elastic actuating element 2631 to form an integral structure.

[0042] In actual use, the user moves the baffle to make the filter screen slide in the filter sliding groove 27. During the sliding of the filter screen 26, the elastic actuating member 2631 comes into contact with the actuating protrusion 271. The actuating protrusion 271 forces the elastic actuating member 2631 to deform. After the elastic actuating member 2631 passes the actuating protrusion 271, the elastic actuating member 2631 rebounds and generates vibration. The elastic actuating member 2631 transmits the vibration to the surface of the filter screen body 262, thereby shaking up the filter residue and preventing the filter residue from adhering to the surface of the filter screen and being unable to be discharged smoothly from the slag discharge port 2212.

[0043] The working principle of this application is as follows: Before the material is fed into the housing 2, the filter screen 26 is positioned directly opposite the feeding port 22. The guide shaft 25 is adjusted so that it is clamped between the two teeth of the tilting gear ring 21. After the material is poured into the housing, the guide shaft 25 is slid so that the baffle plate 23 is positioned directly opposite the feeding port 22, thereby closing the feeding port 22. After the material is stirred, the guide shaft 25 is slid to remove the filter screen body 262. Then, the feeding port 22 is adjusted to a suitable size by blocking it with the baffle plate 23. The tilting gear 111 is activated to adjust the housing 2 to the optimal tilting angle so that the material is poured out of the housing 2.

[0044] 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.
