The stress block 110 drives the connecting block 111 to move upward. The connecting block 111 drives the cover plate 103 to move upward, so that the plurality of limiting rods 114 respectively slide out of the corresponding abutting grooves 122. Then, the two guide rods 113 on the sieve mesh 104 are taken out from the two guide grooves 121. Insert the two guide rods 113 of the new sieve mesh 104 into the corresponding guide grooves 121. Then, the first motor 106 reverses to indirectly drive the plurality of limiting rods 114 to be respectively inserted into the corresponding abutting grooves 122 to limit the sieve mesh 104. And the soil can be crushed through the crushing assembly. In this way, it is convenient to replace the sieve mesh 104 when the sieve mesh 104 is damaged.
