The sand transport pipe 31 is plugged into the inside of the box body 1, and the sand transport pipe 31 is connected to the shaftless spiral 32 through a bearing. The shaftless spiral 32 passes through the right side of the sand transport pipe 31 and is connected to the motor 33, and the motor 33 is located on the right side of the sand transport pipe 31. The lower right side of the sand transport pipe 31 is connected to the motor 33. A discharge port is provided at the end, and the discharge port of the sand transport pipe 31 is located at the lower side of the shaftless spiral 32. The lower end of the discharge port of the sand transport pipe 31 is connected to a sand discharge pipe 34. A slot 4 is provided at the upper end of the sand transport pipe 31 in the box body 1. A slope 5 is provided on the left side of the box body 1, and the slope 5 is connected to the left end of the sand transport pipe 31. Two groups of filter plates 6 are connected to the slope 5, and the filter plates 6 are connected to the inner wall of the box body 1. A water outlet pipe 7 is connected to the upper left end of the box body 1, and a water pump 8 is connected to the water outlet pipe 7, and the water pump 8 is located on the left side of the box body 1. The box body 1 is connected to a water inlet pipe 2, through which raw water is input into the box body 1. A sand discharge mechanism 3 is provided in the box body 1. The sand discharge mechanism 3 rotates in the sand transport pipe 31 through a shaftless screw 32 connected to a motor 33. The slot 4 on the sand transport pipe 31 allows the sand in the raw water to fall into the sand transport pipe 31, and the sand is discharged through the sand discharge pipe 34 through the shaftless screw 32. The slope 5 in the box body 1 allows the sand to slide into the sand transport pipe 31. Two groups of filter plates 6 are connected to the slope 5, and the sand is filtered out through the filter plates 6. Therefore, the filtered water is discharged from the water outlet pipe 7 through the water pump 8, and the sand-blocking mesh plate 11 in the water outlet pipe 7 is filtered again, so that the raw water will not cause damage to the water pump 8 or the inner wall of the pipe during transportation. The sand in the raw water can be discharged and processed through the sand discharge mechanism 3.

[0020] Combine Figure 1 and Figure 2 As shown, a groove is provided in the box body 1 to match the sand transport pipe 31, and the surface of the notch 4 is parallel to the inner bottom wall of the box body 1. The groove in the box body 1 allows the sand transport pipe 31 to fit, and the surface of the notch 4 is parallel to the inner bottom wall of the box body 1 so that the fallen mud and sand can enter the sand transport pipe 31.

[0021] Combine Figure 1 and Figure 2As shown, the right end of the sand transport pipe 31 is connected to a protective cover 9, and the protective cover 9 is located outside the motor 33. A heat dissipation hole 10 is opened on the right side of the protective cover 9. The protective cover 9 at the right end of the sand transport pipe 31 protects the motor 33, and the heat dissipation hole 10 opened by the protective cover 9 enables the motor 33 to dissipate heat.

[0022] like Figure 3 As shown, the apertures of the two groups of filter plates 6 decrease from right to left, and a sand blocking mesh plate 11 is provided in the outlet pipe 7. The sand blocking mesh plate 11 is located on the left side of the filter plates 6, and the aperture of the sand blocking mesh plate 11 is smaller than the aperture of the left filter plate 6. The apertures of the filter plates 6 decrease in sequence, so that sediments of different sizes can be filtered and finally filtered again by the sand blocking mesh plate 11.

[0025] During operation, the box body 1 is connected with a water inlet pipe 2, through which raw water is input into the box body 1. A sand discharge mechanism 3 is provided in the box body 1. The sand discharge mechanism 3 rotates in the sand transport pipe 31 through a shaftless screw 32 connected to a motor 33. The notch 4 provided on the sand transport pipe 31 allows the sand in the raw water to fall into the sand transport pipe 31, and the sand is discharged through the sand discharge pipe 34 through the shaftless screw 32. The slope 5 in the box body 1 allows the sand to slide into the sand transport pipe 31. The anti-slip seal at the right end of the sand transport pipe 31 The protective cover 9 protects the motor 33, and the heat dissipation holes 10 opened in the protective cover 9 enable the motor 33 to dissipate heat. Two sets of filter plates 6 are connected to the slope 5, and the sand is filtered through the filter plates 6. Therefore, the filtered water is discharged from the outlet pipe 7 through the water pump 8, and the sand-blocking mesh plate 11 in the outlet pipe 7 is filtered again, so that the raw water will not cause damage to the water pump 8 or the inner wall of the pipe during transportation. The sand in the raw water can be discharged through the sand discharge mechanism 3.
