(4) Activating the vibration seat 1 to enable the soil on the screen 32 to vibrate and screen;
(5) Repeating the steps (1) to (4) until the soil is completely sieved.
According to the above step (1), the locking of the flip 311 on the screen frame 31 can be released by only pulling the rotating shaft 77, and the screen 32 can be rotated from the horizontal state to the vertical state while the flip 311 is opened to the horizontal state, so that the unscreened soil on the screen 32 can be poured onto the flip 311, and a grinding foundation is provided for grinding the unscreened soil on the flip 311. Compared with a series of operations of unscrewing the pressing seat 6, taking the sieve cover 4 out, taking the sieve body 3 out and pouring the soil which is not sieved in the sieve body 3 on the wood board for grinding in the background art, the method is simpler and more convenient.
According to the above step (2), the flip 311 turned to the horizontal state can be used as a wood board for grinding the soil which is not screened. Moreover, when the flip 311 rotates to be horizontal, because the bottom of the scissor rod 76 on the fixed seat 73 is propped against the side wall of the housing 7811 of the elastic limit seat 781, the bottom of the scissor rod 76 on the movable seat 72 is propped against the side wall of the vibration seat 1, when the flip 311 is pressed downwards, the movable seat 72 and the scissor rod 76 on the fixed seat 73 can be limited in the horizontal direction, so that the horizontal state of the flip 311 can be maintained when the soil is ground, and the stability of the grinding process is improved.
As can be seen from the above step (3), the cover 311 can be closed by only pressing the elastic limiting seat 781 and pushing up the rotating shaft 77, and the ground soil can be poured onto the screen 32 to be screened by vibration. Compared with a series of operations of pouring the ground soil into the screen body 3 again, putting the screen body 3 on the bearing box 2 again, covering the screen cover 4 and screwing the pressing seat 6 to press the screen cover 4 again in the prior art, the method is simpler and more convenient.
In summary, in the soil screening apparatus of the present embodiment, since the flip 311 and the screen 32 are mounted together, the flip 311 and the screen 32 can be operated together. On the one hand, when the turnover cover 311 is turned to a horizontal state, the screen mesh 32 can rotate together to a vertical state, so that the unscreened soil on the screen mesh 32 can be poured onto the turnover cover 311, and a grinding foundation is provided for grinding the unscreened soil on the turnover cover 311, and compared with a series of operations of 'unscrewing the pressing seat 6, taking the screen cover 4, taking out the screen body 3 and pouring the unscreened soil in the screen body 3 onto a wood board for grinding' in the prior art, the process is simpler and more convenient; on the other hand, when the flip 311 is turned to the vertical state, the screen 32 can be turned back to the horizontal state together, and the ground soil can fall onto the screen 32 to be screened by vibration, which is simpler than the series of operations of "pouring the ground soil into the screen 3 again, putting the screen 3 onto the receiving box 2 again, covering the screen cover 4, screwing the pressing seat 6 and pressing the screen cover 4 again" in the related art. Therefore, the soil screening device of the embodiment can simplify screening operation and improve screening efficiency.
