A wire brush 209 is provided on the stirring paddle 208. After being screened by the screening unit, the stones enter the cleaning cylinder and are continuously tumbled under the stirring mechanism to achieve thorough cleaning of the stones. This solution uses mechanized stone cleaning, which saves time and effort, saves manpower, and improves cleaning efficiency.

[0028] During specific production, material-moving rods perpendicular to the stirring paddle 208 are arranged at intervals along the length direction thereof, and the material-moving rods are arranged parallel to the stirring shaft, so as to further fully stir the stones, make the stones fully contact with water, and ensure thorough cleaning.

[0029] To further optimize the above scheme, a filter cartridge 210 is provided in the cleaning cylinder 201, and the cleaning cylinder 201 and the filter cartridge 210 are slightly tilted and arranged on the frame 205, and the feed port and the discharge port of the cleaning cylinder 201 and the filter cartridge 210 are respectively arranged on the upper side of the high feed end and the lower side of the low discharge end; a sewage port 203 is provided at the bottom of the cleaning cylinder 201. With the help of the filter net, sewage with mud and sand can flow into the bottom of the cleaning cylinder and be discharged through the sewage port, so that the gravel and the mud and sand can be separated as much as possible, and the gravel cleaning efficiency is improved.

[0030] When making specific Figure 1 As shown, the sewage outlet of the cleaning cylinder 201 is connected to the lower sewage pipe 1 through a branch pipe 211, and a transparent observation window 2 is provided on the branch pipe 211. With the help of the observation window, it is convenient to visually observe whether the drainage of the stone cleaning is clear.

[0031] The working process of the cleaning unit is as follows: when cleaning, add tap water through the water inlet of the cleaning cylinder and start the stirring motor. The stirring paddle with a wire brush fully stirs the stones soaked in the water. After cleaning for a certain period of time, the sewage is discharged from the sewage outlet and clean water is added. Then the stirring and cleaning are continued for a period of time. After repeated several times, the cleaning water becomes clear after meeting the standard requirements. Open the discharge door and discharge the clean stones in the filter cylinder for standby use.

[0032] Further optimize the above technical solution, such as Figure 4 As shown, it also includes a feeding unit 300, the discharge end of the feeding unit 30 is connected to the feed port of the screening unit 100; the feeding unit 300 includes a bracket 301 and a feeding conveyor 302, and the feeding conveyor 302 is tilted on the bracket 301.

A discharge hopper 104 is arranged in the middle of the support frame 103, and the discharge hopper 104 is connected to a collection box 3 below through a discharge pipe 105, and is used to collect small particles of sand screened. The bottom of the vibrating screen 101 is connected to the discharge hopper 104 through a flexible curtain 107, and the discharge hopper 104 is connected to the support frame 103. Among them, the mesh size on the vibrating screen is smaller than the stone size, and only sand particles smaller than the stone required by the test can be leaked. The vibrating screen vibrates up and down under the action of the driving mechanism, and the small particles of sand in the stone leak through the mesh of the vibrating screen to the discharge hopper below, and finally discharged to the collection box.

[0034] As a preferred structure, Figure 1 , 3 As shown, the driving mechanism includes a vibration motor 108, a driving shaft 109 and a plurality of cams 110, wherein the plurality of cams 110 are arranged at intervals on the driving shaft 109, one end of the driving shaft 109 is driven by the vibration motor 108, and the other end is connected to the support frame 103 through a bearing seat; an arc groove matching the cam 110 is arranged at the middle position of the bottom of the vibration screen 101, and flexible curtains 107 are arranged on both sides of the driving shaft 109, and the vibration requirements of the vibration screen can be met by means of the flexible curtains. The vibration motor drives the plurality of cams on the driving shaft to rotate simultaneously, and the vibration screen realizes up and down vibration under the action of the cams.

[0035] In the specific design, the vibration motor 108 is arranged on the support frame 103, and the vibration motor 108 is connected to the drive shaft 109 through the belt transmission assembly 111. The belt transmission assembly includes a driving pulley, a belt and a driven pulley, the driving pulley is coaxially fixed with the vibration motor, the driven pulley is coaxially fixed with the drive shaft, and the belt connects the driving pulley and the driven pulley, so that the power of the vibration motor can be transmitted to the drive shaft.

[0036] When the stones are vibrated and screened in the vibrating screen, in order to reduce dust, a dust shield 106 is provided at the top of the feed port of the vibrating screen 101 .

[0037] In summary, the utility model has the advantages of compact structure, high mechanization degree and good cleaning effect. The vibrating screen is used to preliminarily screen the stones to ensure that the stone size meets the test requirements. Then the stones enter the filter cylinder in the cleaning cylinder, and the stirring motor is started after adding tap water. After a certain period of time, the sewage is discharged from the sewage outlet of the cleaning cylinder and clean water is added. Then, the stirring and cleaning is continued for a period of time. After repeated several times, the cleaning water becomes clear as required by the standard. The discharge door can be opened to discharge the stones in the filter cylinder for the next test. The use of this solution instead of manual scrubbing of stones greatly improves the cleaning efficiency, reduces manpower input, and thus reduces the cleaning cost.
