In this embodiment, access panel 211 is used for overhauing sieve 22, can overhaul the sieve of damage at any time through the access panel, because the degree of wear of heavy granule material and light granule material is different, if only set up access panel 211 in one end, inconvenient the maintenance when the other end damages.
Further, a fine particle outlet 2111 is arranged at the lower part of one end of the sieve box 21, which is provided with the heavy particle outlet 219, and the fine particle outlet 2111 is located below the sieve plate 22. In this embodiment, the fine particle outlet 2111 provides an outlet for discharging the fine particles, and the fine particles fall through the sieve holes after being sieved by the sieve plate 22 and fall onto the sieve box bottom plate 218, gradually move toward the fine particle outlet 2111 under the action of the vibration force, and are finally discharged from the fine particle outlet 2111.
Further, a viewing window 214 is provided above the fine particle outlet 2111. In this embodiment, when the air locking and discharging mechanism breaks down or regularly checks the air locking and discharging mechanism, the observation window 214 can be opened to check the state of the air locking and discharging mechanism or maintain the air locking and discharging mechanism, so that the maintenance is simpler, and the maintenance cost of the equipment is reduced.
Further, a support beam 215 is disposed inside the screen box 21.
Further, a reinforcing rib plate is arranged at the position where the supporting beam 215 is connected with the screen box 21.
In this embodiment, the support beam 215 is used to support the screen box 21, so as to increase the bearing strength of the screen box 21; the addition of the reinforcing ribs is beneficial to increasing the connection strength of the support beam 215 and the screen box 21.
Further, a support seat 213 for supporting the sieve box 21 is provided at the bottom of the sieve box 21.
