Anti-caking sand screening machine

Abstract

The invention relates to an anti-caking sand screening machine. The machine comprises a main body, a screen, a vibrator, a feeding pipe, a discharging pipe, two supporting legs, an anti-caking mechanism and two dustproof mechanisms, the anti-caking mechanism comprises a connecting rod, two air cylinders, two anti-caking assemblies and a plurality of pressing blocks, each anti-caking assembly comprises a rotating plate, a lead screw, a first bearing, a ball screw bearing, a hinge rod, a supporting rod and a plurality of smashing rods, and each dustproof mechanism comprises a dustproof box, an inlet pipe, an exhaust pipe, a filter screen, a power shaft, a second bearing, fan blades, a gear and a rack. The anti-caking sand screening machine can crush sand and stone materials through the anti-caking mechanism, the probability of sand and stone caking is reduced, the situation that sands and stones are caked and cannot pass through the screen is avoided, the practicability of the machine isimproved, the dustproof function is achieved through the dustproof mechanisms, the situation that dust generated in the sand screening process overflows and influences the surrounding environment isavoided, meanwhile, the situation that a user adsorbs the dust and body health is influenced is also avoided, and therefore the reliability of the machine is improved.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to an anti-caking sand screening machine. Background technique [0002] Sand screening machine, also known as dry land sand screening ship, sand and gravel separator, is a sand and gravel separation equipment suitable for rivers, reservoirs, and coal yards. It consists of hull, frame, reducer, conveyor belt, rotary screen, engine or motor. This model is simple in structure, economical and applicable, and easy to operate. Divided into drum sand screening machine, washing drum sand screening machine, vibrating screen sand screening machine and so on. [0003] When the existing sand screening machine screens sand, if the external environment is relatively humid, it is easy to cause sand and stones to agglomerate, so that the sand and stones cannot pass through the screen and affect the sand screening work. Not only that, the existing sand screening machine If the dust is scatte...

Problems solved by technology

[0003] When the existing sand screening machine screens sand, if the external environment is relatively humid, it is easy to cause sand and stones to agglomerate, so that the sand and stones cannot pass through the screen and affect the sand screening work. Not only that, the existing sand screening machine If the dust is scattered, it will easily cause pollution to the surrounding environment. If the dust is inhaled by the staff, it will pose a threat to the health of the staff and reduce the reliability of the existing sand screening machine.
