[0024] See also Figure 1-3 Two symmetrically arranged reciprocating springs 10 are sleeved on the two directional rods 9, and the reciprocating springs 10 are commonly connected between the carrier box 6 and the bracket 5. A T-slot is provided inside the carrier box 6, and the sieve plate 7 is nested inside the T-slot. A limiting groove 111 is provided inside the sieve plate 7, and an arc-shaped latch 106 is nested inside the limiting groove 111. A large slide groove 109 and a small slide groove 110 are respectively provided inside the carrier box 6, and an inclined sliding block 103 is slidably connected inside the large slide groove 109.

A tension spring 108 is commonly connected between the arc-shaped latch 106 and the inner wall of the small slide groove 110.

[0025] The specific implementation process of the utility model is as follows: first, pour the soil sample to be screened into the interior of the device housing 2 through the inlet 12, and all the soil falls on the sieve plate 7. At this time, the telescopic cylinder 8 connected to the power is started to periodically expand and contract. When the telescopic cylinder 8 is extended, the two buffer pads 11 push the carrier box 6 to move to one side. At this time, the reciprocating springs 10 on both sides of the carrier box 6 respectively accumulate potential energies of opposite nature. When the telescopic cylinder 8 contracts, the reciprocating spring 10 drives the sieve plate 7 to reciprocate. When the elastic potential energy gradually decreases, the telescopic cylinder 8 is extended again to supply thrust, so that the carrier box 6 can continuously reciprocate to screen out large and small particles of soil and impurities;

[0026] After each screening, the inner wall of the sieve plate 7 is contaminated with a lot of soil samples, and needs to be cleaned in time to ensure the independence and purity of each screening. At this time, the movable cap 101 can be pulled to drive the inclined slider 103 to move through the movable rod 102. At this time, the arc-shaped latch 106 withdraws from the interior of the limit groove 111 under the pulling force of the tension spring 108, so that the sieve plate 7 can be pulled out, and then the movable cap 101 is released. Since the thrust of the thrust spring 107 is greater than the pulling force of the tension spring 108 in the natural state, the inclined slider 103 drives the inclined slider 2 104 to move under the thrust of the thrust spring 107, so that the arc-shaped latch 106 slides to the outside of the carrier box 6;

[0027] When the sieve plate 7 is cleaned or replaced with a new one, it is only necessary to align the sieve plate 7 with the T-slot and insert the sieve plate 7. Since the arc-shaped latch 106 has an arc surface, it can be driven to move until the arc-shaped latch 106 is aligned with the limiting groove 111. At this time, the arc-shaped latch 106 will be embedded in the limiting groove 111 according to the above principle to complete the fixation.

[0028] Furthermore, when the device is running, the door 3 is opened and closed to avoid dust pollution, the universal pulley 4 allows the device to be moved conveniently, and the handle 15 is provided with skin-friendly silicone, so that the material receiving box 13 feels comfortable and more labor-saving when being pulled.
