[0002] In the process of construction, a mixing device is needed to mix sand and gravel, so as to facilitate the mixing of sand, gravel and concrete. However, the general sand and gravel mixing device cannot filter the sand and gravel when in use. At the same time, during the mixing process, the mixing shaft is only used to drive the sand and gravel to rotate, resulting in poor overall mixing effect. Utility Model Content
[0003] The purpose of the utility model is to provide a sand and gravel mixing device to solve the problems raised in the above background technology.
[0004] A sand and gravel mixing device comprises a frame and a feed hopper: the upper end of the frame is provided with the feed hopper, the interior of the feed hopper is provided with a filtering mechanism, the lower end of the interior of the frame is spherical, and the interior of the frame is provided with a mixing mechanism.

[0006] When the device is in use, the sand and gravel are filtered through the inclined filter plate, so that the sand and gravel flow downward along the filter plate, and the filter plate can filter larger sand and gravel, so that the larger sand and gravel flow downward along the filter plate and then flow out to the outside through the sand discharge port.
[0007] Preferably, an inclined guide plate is provided on the inner side of the frame, and the guide plate is located above the filter plate.
[0008] When the material is added into the feed hopper, the guide plate can guide the incoming material so that the material moves to the uppermost end of the filter plate, and then the filter plate filters the sand and gravel.

At the same time, the limit block can also play a guiding role, which is convenient for sand and gravel to flow into the surface of the filter plate. The guide plate and the feed hopper are fixed by bolts, and the gap between the guide plate and the middle piece of the filter plate can be adjusted according to needs, so as to avoid the phenomenon of sand and gravel bouncing on the surface of the filter plate.
[0011] Preferably, the supporting mechanism includes a fixed plate, a first spring, a support rod and a guide wheel. The fixed plate is in an "L" shape. One end of the fixed plate is connected to the feed hopper, and the other end of the fixed plate is internally provided with a first spring and a support rod.

[0012] The first spring pushes the support rod to move outward, thereby supporting the filter plate through the guide wheel. When sand and gravel impact the filter plate, the filter plate will be deflected downward. Then the first spring will drive the support rod and the guide wheel to move outward, thereby pushing the filter plate back to its original position.
[0013] Preferably, the stirring mechanism includes a motor, a rotating shaft and a stirring plate, the motor is arranged on the side of the frame, a rotating shaft is rotatably arranged inside the frame, the rotating shaft is connected to the output end of the motor, and a stirring plate is slidably arranged at equal angles on the side of the rotating shaft.
[0014] When the device is in use, the motor drives the rotating shaft to rotate, so that the stirring plate is used to stir and mix the sand and gravel.
[0015] Preferably, a connecting rod is provided on the side of the stirring plate, and the connecting rod is slidably arranged inside the rotating shaft. A second spring is provided on the side of the connecting rod, and the second spring is arranged inside the rotating shaft.
[0016] When the device is in use, when the stirring plate is subjected to greater force, it will move relative to the rotating shaft, and the second spring will be compressed. The front cross-section of the stirring plate will be in a "V" shape, and the sand and gravel will be driven to move through the stirring plate. When the stirring plate is subjected to less resistance, the second spring will push the stirring plate to return to its original position, thereby throwing out the material. Since the stirring plate is in a "V" shape, the sand and gravel can be placed around, thereby increasing the stirring effect of the sand and gravel.
[0017] Preferably, a discharge port is provided at the lower end of the frame.
[0018] The material can be discharged through the discharge port. Since the interior of the frame is spherical, the material will move downward along the slope of the frame and concentrate at the discharge port, making it easier to collect the material.

[0020] 1. When the device is in use, the filter plate will be used to filter the sand and gravel, and then the stirring plate will be used to stir and mix the sand and gravel. During the stirring process, the acceleration of the stirring plate will be continuously used to eject the material to the surroundings, thereby increasing the stirring effect of the device.

[0031] When the device is in use, the sand and gravel are filtered through the inclined filter plate 6, so that the sand and gravel flow downward along the filter plate 6, and the filter plate 6 can filter larger sand and gravel, so that the larger sand and gravel flow downward along the filter plate 6 and then flow out to the outside through the sand discharge port 4.
[0032] An inclined guide plate 3 is arranged inside the frame 1 , and the guide plate 3 is located above the filter plate 6 .
[0033] When materials are added into the feed hopper 2 , the guide plate 3 can guide the incoming materials so that the materials move to the uppermost end of the filter plate 6 , and then the filter plate 6 filters the sand and gravel.
[0034] The side surfaces of the feed hopper 2 are respectively provided with a limit block 7 and a support mechanism with an arc-shaped upper side. The limit block 7 and the support mechanism are respectively located at the upper and lower ends of the filter plate 6.
[0035] The upper end of the filter plate 6 can be limited by the limit block 7, and then the lower end of the filter plate 6 can be limited by the support mechanism. At the same time, the limit block 7 can also play a guiding role, which is convenient for sand and gravel to flow into the surface of the filter plate 6. The guide plate 3 and the feed hopper 2 are fixed by bolts, and the gap between the guide plate 3 and the middle piece of the filter plate 6 can be adjusted according to needs, so as to avoid the phenomenon of sand and gravel bouncing on the surface of the filter plate 6.
[0036] The supporting mechanism includes a fixed plate 8, a first spring 9, a support rod 10 and a guide wheel 11. The fixed plate 8 is "L"-shaped.

[0037] The first spring 9 pushes the support rod 10 to move outward, thereby supporting the filter plate 6 through the guide wheel 11. When sand and gravel impact the filter plate 6, the filter plate 6 will be deflected downward. Then the first spring 9 will drive the support rod 10 and the guide wheel 11 to move outward, thereby pushing the filter plate 6 to return to its original position.
