[0033] Specifically, the separation assembly includes: a discharge pipe 3, arranged at the bottom of the separation box 1; and a collection box 5, arranged on one side of the separation box 1 and located at the bottom of the guide plate 4.
[0034] The separated sand and gravel are discharged through the discharge pipe 3, and the impurities guided by the guide plate 4 fall into the collection box 5, so as to achieve separate collection of sand and gravel and impurities.
[0035] Specifically, the vibration assembly includes a spring 8, one end of which is connected to the separation box 1 and the other end of which is connected to the telescopic rod 7.
[0036] As a preferred implementation, when the vibration motor 6 is working, the spring 8 extends and retracts to enhance the vibration effect of the separation box 1, improve the filtration efficiency of the filter screen 2, and prevent clogging.
