[0003] In existing technologies, traditional sand and gravel separators use vibration to separate sand and gravel. However, vibration can cause severe wear and tear on the equipment, shorten its service life, and increase the cost of maintenance and replacement parts. Utility Model Content
[0004] The purpose of this utility model is to provide a sand and gravel separation device for the reuse of concrete aggregates, which aims to solve the problem that the traditional sand and gravel separators in the prior art separate sand and gravel by means of vibration, but vibration will cause serious wear and tear on the equipment, shorten its service life, and increase the cost of maintenance and replacement parts.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A sand and gravel separation device for the reuse of concrete aggregates includes:
[0007] Support frame;
[0008] A mixing assembly includes a filter screen bucket, a support, a fixing plate, a stone discharge port, a motor, a rotating rod, and a fixing frame. The support is fixedly connected to the surface of the support frame, the filter screen bucket is rotatably connected to the surface of the support, the fixing plate is fixedly connected to the surface of the support frame, the motor is fixedly connected to the surface of the fixing plate, the fixing frame is fixedly connected to the surface of the filter screen bucket, the rotating rod is fixedly connected to the surface of the fixing frame, the output end of the motor is fixedly connected to one end of the rotating rod, and the stone discharge port is opened on the surface of the filter screen bucket.
[0009] A sand discharge assembly is disposed on one side of the filter screen barrel;
[0010] A feeding assembly is disposed on one side of a fixed plate.
[0011] As a preferred embodiment of this utility model, the sand discharge assembly includes a support plate and a sand discharge pipe. The support plate is disposed on the upper surface of the support frame, and the sand discharge pipe is fixedly connected to the surface of the support plate.
[0012] In a preferred embodiment of this utility model, the feeding assembly includes a feeding channel and a feeding port, the feeding port being opened on the surface of the fixed plate, and the feeding channel being fixedly connected to the surface of the fixed plate.

[0015] As a preferred embodiment of this utility model, the filter screen barrel is made of stainless steel.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. In this solution, after the concrete and gravel are slowly poured into the filter screen bucket, the motor is started, which drives the rotating rod to rotate, thereby causing the filter screen bucket to rotate. Since the surface of the filter screen bucket has gaps and is slightly inclined, the mud and sand will flow out through these gaps, while the concrete and gravel will slowly slide down the inclined surface of the screen to the stone discharge port at the bottom. When it reaches the stone discharge port, the remaining stones are discharged from there, completing the separation process. This device utilizes the rotation and tilting design to effectively reduce the wear of parts without relying on vibration, and achieves efficient sand and gravel separation.
[0018] 2. In this solution, by using this device, sand and gravel separation is achieved without vibration, which greatly reduces noise and improves the quality of the working environment. Attached Figure Description

Example
[0025] Please see Figures 1-3 The present invention provides the following technical solution:
[0026] A sand and gravel separation device for the reuse of concrete aggregates includes:
[0027] Support frame 2;
[0028] The mixing assembly includes a filter screen bucket 5, a support 6, a fixing plate 8, a stone discharge port 10, a motor 11, a rotating rod 13, and a fixing frame 14. The support 6 is fixedly connected to the surface of the support frame 2, the filter screen bucket 5 is rotatably connected to the surface of the support 6, the fixing plate 8 is fixedly connected to the surface of the support frame 2, the motor 11 is fixedly connected to the surface of the fixing plate 8, the fixing frame 14 is fixedly connected to the surface of the filter screen bucket 5, the rotating rod 13 is fixedly connected to the surface of the fixing frame 14, the output end of the motor 11 is fixedly connected to one end of the rotating rod 13, and the stone discharge port 10 is opened on the surface of the filter screen bucket 5.
[0029] The sand discharge assembly is located on one side of the filter screen barrel 5;
[0030] The feeding assembly is located on one side of the fixed plate 8.
[0031] In a specific embodiment of this utility model, after the concrete and gravel are slowly poured into the filter screen bucket 5, the motor 11 is turned to drive the rotating rod 13 to rotate, and then the filter screen bucket 5 will rotate accordingly, allowing the mud and sand in the concrete and gravel to flow out through the gaps on the surface of the filter screen bucket 5. Since the filter screen bucket 5 is slightly tilted, the concrete and gravel will slowly flow down to the stone discharge port 10. When the concrete and gravel flow to the stone discharge port 10, the mud and sand inside will flow out completely through the gaps in the filter screen bucket 5, and the remaining stones will be discharged from the stone discharge port 10. By using this device, sand and gravel separation can be performed without vibration and wear on the parts.
[0032] Please refer to the details. Figures 1-3 The sand discharge assembly includes a support plate 3 and a sand discharge pipe 4. The support plate 3 is disposed on the upper surface of the support frame 2, and the sand discharge pipe 4 is fixedly connected to the surface of the support plate 3.
[0033] In this embodiment, the mud and sand flowing out of the gaps in the filter screen 5 will fall into the sand discharge pipe 4 and be discharged away.
[0034] Please refer to the details. Figures 1-3 The feeding assembly includes a feeding channel 9 and a feeding port 12. The feeding port 12 is opened on the surface of the fixed plate 8, and the feeding channel 9 is fixedly connected to the surface of the fixed plate 8.
[0035] In this embodiment: concrete and aggregate are poured into the feed channel 9 and then slid into the filter screen bucket 5 through the feed inlet 12.
[0036] Please refer to the details. Figures 1-3 The surface of the support 6 is fixedly connected with a stone drainage channel 7.
[0037] In this embodiment, the stones discharged from the stone discharge port 10 will fall into the stone discharge channel 7 and be discharged.
[0038] Please refer to the details. Figures 1-3 The lower end of the support frame 2 is fixedly connected to multiple table legs 1.
[0039] In this embodiment, the table leg 1 has a structure that is narrower at the top and wider at the bottom, which provides better stability.
[0040] Please refer to the details. Figures 1-3 The filter screen 5 is made of stainless steel.
[0041] In this embodiment, the filter screen 5 is made of stainless steel because stainless steel has wear-resistant properties. It can not only resist the friction of hard materials such as sand and gravel, but also maintain good structural integrity in harsh working environments.
[0042] It should be noted that the specific model of motor 11 used shall be selected by those skilled in the art, and the above-mentioned motor 11 and other related technologies are all existing technologies, which will not be elaborated in this solution.
[0043] The working principle and usage process of this utility model are as follows: When concrete and aggregate are slowly poured into the feed channel 9, and then slide into the filter screen bucket 5 through the feed inlet 12, the motor 11 is turned to drive the rotating rod 13 to rotate. The filter screen bucket 5 will then rotate, causing the mud and sand in the concrete and aggregate to flow out through the gaps on the surface of the filter screen bucket 5 and fall into the sand discharge pipe 4 for discharge. Because the filter screen bucket 5 is slightly tilted, the concrete and aggregate will slowly flow down to the stone discharge port 10. When the concrete and aggregate flow to the stone discharge port 10, the mud and sand inside will flow out through the gaps in the filter screen bucket 5, and the remaining stones will be discharged from the stone discharge port 10. By using this device, sand and aggregate can be separated without vibration and wear on the parts, thus solving the problem that traditional sand and aggregate separators separate sand and aggregate by vibration, but vibration will cause serious wear on the equipment, shorten its service life, and increase the cost of maintenance and replacement parts.
[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
