[0027] Furthermore, the middle end of the right side of the crushing box 4 is fixedly connected to the mounting plate 11 by bolts, the middle end of the top of the mounting plate 11 is fixedly installed with a vibrator 10 by bolts, the bottom of the vibrator 10 is fixedly connected to a vibrating rod 9, the left side of the vibrating rod 9 is fixedly connected to a screening plate 8, the bottom of the screening plate 8 is fixedly connected to the top of the base plate 1 through a connecting plate, and screening is performed by vibration.

[0028] Furthermore, a charging port 17 is provided at the middle end of one side of the battery box 18 , and an output end of the charging port 17 is electrically connected to an input end of the battery 19 in a one-way manner.

[0029] Furthermore, the outer side of the cross bar 6 is fixedly connected to the heating box 2, the middle end of the inner cavity of the heating box 2 is fixedly connected to the second heating tube 23 by bolts, the middle end of the top of the heating box 2 is fixedly installed with a fan 3 by bolts, the input end of the fan 3 is connected to the upper ends of the left and right sides of the heating box 2 through a pipe, the output end of the fan 3 is fixedly connected to the exhaust plate 15 through a pipe, and the bottom of the exhaust plate 15 is fixedly connected to the exhaust hood 16, which can heat the sand again to prevent the sand from accumulating and agglomerating.

[0030] Furthermore, an air inlet is provided at the bottom of the heating box 2, and the air inlet is a rectangular structure.

[0031] Furthermore, support legs are fixedly connected to the left and right sides of the bottom of the base plate 1, and anti-slip pads are provided at the bottom of the support legs.

[0032] Working principle: First, add sand into the inner cavity of the crushing box 4. The sand entering the inner cavity of the crushing box 4 will first come into contact with the first heating tube 13. The sand can be preheated through the first heating tube 13 to evaporate part of the water in the sand.

[0033] Secondly, the motor 20 is started to work, and the motor 20 drives the second rotating roller 21 to rotate, and the second rotating roller 21 drives the second gear 24 to rotate, and the second gear 24 drives the first gear 22 to rotate, and the first gear 22 drives the first rotating roller 14 to rotate. Since there is a certain gap between the first rotating roller 14 and the second rotating roller 21, when sand enters the inner cavity of the crushing box 4, the sand will be crushed by the gap between the first rotating roller 14 and the second rotating roller 21, which can prevent the sand from agglomerating. At the same time, the fan 3 will be started to work, and air will be drawn into the inner cavity of the heating box 2 through the fan 3. The air enters the inner cavity of the heating box 2 and contacts with the second heating tube 23 for heating. The heated air is transported to the inner cavity of the exhaust plate 15 through the fan 3, and then transported to the inner cavity of the exhaust hood 16 through the exhaust plate 15. The hot air is transported out through the exhaust hood 16 and contacts the top of the first rotating roller 14 and the second rotating roller 21. The hot air heats and dries the sand again, and the dried and crushed sieve falls on the top of the screening plate 8.

[0034] Finally, the work is started by starting the vibrator 10, generating vibration force through the vibrator 10, and transmitting the vibration force to the screening plate 8 through the vibration rod 9. The screening plate 8 continuously vibrates to screen the sand on the top. At the same time, it can also prevent sand from clogging the screening plate 8, thereby improving the sand screening efficiency.
