Description

Technical Field

[0001] The utility model belongs to the technical field of concrete recycling, and in particular relates to waste concrete recycling equipment. Background Art

[0002] Recycled concrete refers to the new concrete made by crushing, cleaning and grading discarded concrete blocks, mixing them in a certain proportion to replace part or all of the natural aggregates, and then adding cement, water, etc. Recycled concrete is classified according to the combination of aggregates. Recycled concrete preparation equipment is required for its preparation; when preparing concrete, existing concrete preparation equipment needs to be cleaned and graded after crushing.

[0003] For example, the Chinese utility model patent document with announcement number CN219682678U describes a device for preparing environmentally friendly recycled concrete. Although the device uses an impact crushing mechanism to crush large concrete stones and transports the crushed materials to the outside of the body through a conveyor belt, this structural design has significant defects. Specifically, the impact crushing method cannot fully refine the concrete stones, resulting in the crushed stones still being large in size. When these large concrete stones fall directly from a high altitude onto the conveyor belt, the conveyor belt will be subjected to a strong impact force, causing deformation or even damage. To make matters worse, once the conveyor belt is deformed, its rebound effect may cause the concrete stones to bounce up, thereby increasing the risk of damaging the internal structure of the device.

[0004] Therefore, it is very necessary to invent a waste concrete recycling device. Utility Model Content

[0006] The concrete conveying mechanism includes a conveyor box, a rotating chamber, a feeding chamber, a feeding wheel, a wheel groove, a transmission gear and a driving motor. The conveyor box is fixedly installed in the concrete crusher box through a connecting plate. The rotating chamber and the feeding chamber are provided inside the conveyor box. The feeding wheel is rotatably installed inside the conveyor box. The feeding wheel is provided with a plurality of wheel grooves.

[0007] Preferably, the conveyor box is a rectangular structure, the upper slot of the conveyor box is the feed slot, the lower slot is the discharge slot, the material drop area is below the crushing area between the breaking wheel and the crushing wall, and the feed slot of the conveyor box is located above the material drop area.

[0008] Preferably, the wheel groove opened on the feeding wheel allows concrete material to enter and is used to convey concrete material. Two feeding wheels on the same horizontal line form a group, and multiple groups of feeding wheels are arranged inside the conveyor box, and the feeding cavity between each group is a material transition cavity.

[0009] Preferably, the feeding chamber is communicated with the rotating chamber, the rotating chamber is an arc-shaped chamber, and the two rotating chambers together form an annular chamber.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model cleverly adds a concrete conveying mechanism between the impact crushing mechanism and the conveyor belt mechanism, abandons the traditional conveying method, and innovatively adopts a wheeled feeding method.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a waste concrete recycling device, comprising a concrete crushing machine box 1, a concrete conveying mechanism 2, a broken wheel 3 and a crushing wall 4, wherein the concrete conveying mechanism 2 is installed inside the concrete crushing machine box 1, the concrete conveying mechanism 2 is located below the broken wheel 3 and the crushing wall 4, the broken wheel 3 and the crushing wall 4 are installed inside the concrete crushing machine box 1, and either end of the broken wheel 3 rotates through the concrete crushing machine box 1 and is fixedly connected to the output end of a motor fixedly installed outside the concrete crushing machine box 1.

[0022] The concrete conveying mechanism 2 includes a conveyor box 21, a rotating chamber 22, a feeding chamber 23, a feeding wheel 24, a wheel groove 25, a transmission gear 26 and a driving motor 27. The conveyor box 21 is fixedly installed in the concrete crusher box 1 through a connecting plate. The conveyor box 21 is provided with the rotating chamber 22 and the feeding chamber 23. The feeding wheel 24 is rotatably installed in the conveyor box 21. The feeding wheel 24 is provided with a plurality of wheel grooves 25. One end of the mandrel of the feeding wheel 24 rotates through the conveyor box 21 and is fixedly connected with the transmission gear 26. The two transmission gears 26 are meshed together. The other end of the mandrel of the feeding wheel 24 is fixedly connected with the output end of the driving motor 27 fixedly installed outside the conveyor box 21. The concrete conveying mechanism 2 forms a transition conveying mechanism between the impact crushing mechanism (broken wheel 3 and broken wall 4) and the conveyor belt to eliminate the impact force generated by the concrete stones falling from high altitude.

[0023] Embodiment 1:

[0024] Specifically, the conveyor box 21 is a rectangular structure, the upper slot of the conveyor box 21 is a feed slot, and the lower slot is a discharge slot. The area below the crushing area between the breaking wheel 3 and the crushing wall 4 is a material dropping area, and the feed slot of the conveyor box 21 is located above the material dropping area. This design enables the crushed concrete stones to fall directly and accurately into the conveyor box 21, avoiding the problem of concrete stones falling from high altitude in traditional conveying methods, thereby effectively reducing the risk of equipment damage and improving the safety of the entire processing flow.

[0025] Specifically, the wheel groove 25 provided on the feeding wheel 24 allows the concrete material to enter and is used to transport the concrete material. Two feeding wheels 24 on the same horizontal line form a group, and the setting of the feeding wheels 24 adopts a unique grouping method. They work together to push the material forward and crush it. This grouping design not only improves the conveying efficiency, but also ensures the stability and balance of the material during the conveying process. The conveyor box 21 is provided with multiple groups of the feeding wheels 24, and the feeding cavity 23 between each group is a material transition cavity for temporarily storing and transitioning materials. This design allows the material to transition smoothly during the conveying process, reducing equipment failures and downtime caused by material accumulation or blockage.

[0026] Specifically, the feeding cavity 23 is communicated with the rotating cavity 22, the rotating cavity 22 is an arc-shaped cavity, and the two rotating cavities 22 together form an annular cavity.

[0027] Specifically, the conveyor box 21 is located directly above the conveyor belt mechanism, and the conveyor belt mechanism is installed in the concrete crusher box 1. The upper side and the lower side of the concrete crusher box 1 are respectively provided with a feed port and a discharge port, and the discharge port is located on one side of the conveyor belt mechanism.

[0028] Embodiment 2:

[0029] First, waste concrete enters the equipment through the feed port above the concrete crusher box 1. In the crushing area, the broken wheel 3 and the crushing wall 4 start working. The broken wheel 3 rotates under the drive of the motor and crushes the waste concrete together with the fixed crushing wall 4. In this process, the concrete is broken into smaller particles, which provides convenience for subsequent processing. Then, the crushed concrete blocks fall into the feed slot of the conveyor box 21. Since the conveyor box 21 is located below the broken wheel 3 and the crushing wall 4, and its feed slot is just above the drop area, the crushed concrete blocks can fall directly and accurately into the conveyor box 21, avoiding the problem of concrete blocks falling from high altitude in traditional conveying methods. Inside the conveyor box 21, the feeding wheel 24 starts working. The wheel groove 25 provided on the feeding wheel 24 allows the entry of concrete materials and is transported by the rotation of the feeding wheel 24. At the same time, the setting of the feeding wheels 24 adopts a unique grouping method. Two feeding wheels 24 on the same horizontal line form a group, and multiple groups of feeding wheels 24 work together to push the materials forward. This design not only improves the conveying efficiency, but also ensures the stability and balance of the materials during the conveying process. During the conveying process, the feeding wheels 24 not only convey the materials from the feed slot to the discharge slot, but also further crush and refine the materials through their rotation and the structure of the wheel slot 25. The feeding cavity 23 between each group of feeding wheels 24 serves as a material transition cavity for temporary storage and transition of materials, ensuring the continuity and stability of the materials during the conveying process. Finally, the concrete materials that have been crushed and conveyed are discharged through the discharge slot of the conveyor box 21 and enter the subsequent conveyor belt mechanism for further processing or utilization. The entire processing flow is efficient and continuous, realizing the efficient recycling of waste concrete.

[0030] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
