[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1 to Figure 2 As shown,

[0019] A concrete sand and gravel recovery device, characterized in that it includes a support frame 2, to which a recovery box 3 is fixedly connected, a support plate 4 is provided on the recovery box 3, a feed pipe 5 is passed through the middle of the support plate 4, a filter cartridge 6 is rotatably provided at the lower end of the feed pipe 5, a driving component for driving the filter cartridge 6 to rotate is provided on the support plate 4, a plurality of filter stone holes 7 are provided on the filter cartridge 6, the lower end of the feed pipe 5 is communicated with the upper end of the filter cartridge 6, a fine sand recovery bin 8 is provided in the recovery box 3, a fine sand recovery component is provided on the fine sand recovery bin 8, and a drain pipe 9 is provided at the lower end of the recovery box 3.

[0020] In this embodiment, water for flushing concrete enters the filter cartridge 6 from the feed pipe 5, and the stone filter holes 7 intercept the gravel in the filter cartridge 6, while the fine sand and water pass through the stone filter holes 7 and fall downward and fall on the fine sand recovery component. The fine sand recovery component recovers the fine sand into the fine sand recovery bin 8, and the filtered water falls to the bottom of the recovery box 3 and is discharged from the drain pipe 9; when the filter cartridge 6 filters the gravel, in order to prevent the gravel from blocking the stone filter holes 7 and causing the fine sand to be unable to pass through, the driving component drives the filter cartridge 6 to rotate, so that the gravel rotates in the filter cartridge 6, avoiding the gravel from blocking the stone filter holes 7 and accelerating the separation of fine sand and gravel.

[0021] In this embodiment, the support plate 4 is slidably connected to the recovery box 3, and a push rod motor 10 is fixedly connected to the recovery box 3, and a push rod of the push rod motor 10 is connected to the support plate 4. When the filter cartridge 6 is filtering, the push rod motor 10 drives the support plate 4 and the filter cartridge 6 to move up and down, thereby enhancing the movement effect of the crushed stones in the filter cartridge 6, accelerating the separation of fine sand and crushed stones, and preventing the crushed stones from blocking the filter holes 7.

[0022] In this embodiment, the driving assembly includes a first driving motor 11, which is fixedly connected to the support plate 4, and a gear 12 is fixedly connected to the output shaft of the first driving motor 11. A gear ring 13 is fixedly connected to the upper end of the filter cartridge 6, and the gear ring 13 is rotatably connected to the lower end of the feed pipe 5, and the gear 12 and the gear ring 13 are meshed and connected. The first driving motor 11 drives the gear 12 to rotate, and the gear 12 drives the gear ring 13 and the filter cartridge 6 at the lower end of the gear ring 13 to rotate, so that the crushed stone rotates in the filter cartridge 6.

[0023] In this embodiment, the fine sand recovery assembly includes a rotating rod 14, which is rotatably connected to the fine sand recovery bin 8, a filter screen 15 is fixedly connected to the rotating rod 14, and a second driving motor 16 is provided on the fine sand recovery bin 8 to drive the rotating rod 14 to rotate, and the filter screen 15 can be rotated to the bottom of the filter cylinder 6 or to the fine sand recovery bin 8. The fine sand and water flowing out of the filter stone holes 7 fall onto the filter screen 15, and the filter screen 15 intercepts the fine sand. After a period of use, the second driving motor 16 drives the filter screen 15 to rotate into the fine sand recovery bin 8, and the fine sand intercepted on the surface of the filter screen 15 is poured into the fine sand recovery bin 8, so as to achieve separation and collection of the fine sand.

[0024] In this embodiment, abutment block 17 is fixedly connected in the fine sand recovery bin 8, and when the filter screen 15 rotates, the end of the filter screen 15 can abut against the abutment block 17. When the fine sand on the surface of the filter screen 15 is poured into the fine sand recovery bin 8, the end of the filter screen 15 collides with the abutment block 17, and the fine sand on the filter screen 15 is shaken off.

[0025] In this embodiment, a rubber layer 18 is provided on the abutting block 17. The rubber layer 18 is provided on the abutting block 17, which is beneficial to protecting the filter screen 15.
