Abstract

The utility model provides a sand screening machine, and belongs to the field of machinery. By the sand screening machine, sand can be automatically screened under automatic control, and the sand screening machine can be combined with other conveying equipment to realize line production. The sand screening machine is characterized in that a hopper is mounted on a framework, an oblique sieve is arranged below an outlet at the lower end of the hopper, pulleys are mounted below the sieve and are placed on guide rails, and the guide rails are fixed onto a crossbeam of the framework; a side shaft of the sieve is connected to one end of a fulcrum bar, and the other end of the fulcrum bar is connected onto a rocker arm by a shaft; and a driving gear inside a gearbox is meshed with a medium gear, the medium gear is meshed with a driven gear, a motor drives the driving gear, and the driven gear is coaxial with the rocker arm. The sand screening machine has the advantages that the sand screening machine is simple in structure, convenient to operate and use and low in cost, a raw sand conveyor belt for conveying raw sand into the sand screening machine is mounted at the upper end of the hopper, a screen sand conveying belt is placed below the sieve, screened sand can be directly conveyed into equipment needing the sand, line production is realized, and large quantities of time, labor and materials are saved.

Description

Sand sieving machine

Technical field

The utility model belongs to mechanical field.

Background technology

Develop rapidly due to economy, the high buildings and large mansions in city are also built rapidly, so just need a large amount of sands, the most of employing of the husky equipment of existing sieve manually completed, and has a strong impact on operating efficiency, although in order to accelerate efficient, also respective design some the sieve sands equipment, but the reasons such as it is high due to cost, use inconvenience are seldom adopted, and only some large-scale building constructors can bear so high expense.

Summary of the invention

The purpose of this utility model is to provide a kind of automatic control and carries out the Automatic sieve sand and can form with other conveying equipments the sand sieving machine of continuous productive process.

The utility model is equipped with hopper on frame, be tilting sieve below the outlet of the lower end of hopper, and pulley is installed below sieve, and pulley is placed on guide rail, and guide rail is fixed on crossbeam on frame; One side shaft of sieve is connected to an end of pole, and pole other end axle is connected on rocking arm; The driving gear of gearbox inside and idle wheel engagement, idle wheel and driven gear engagement, the driven by motor driving gear, driven gear is coaxial with rocking arm.

The utility model is simple in structure, and is easy for operation, with low cost, former husky conveyer belt is installed in the hopper upper end is sent into former sand, place the conveyer belt of the sand that is sieved below sieve, can directly send into the equipment that needs sand, reach continuous productive process, saving plenty of time, manpower and materials.

The specific embodiment

The utility model is equipped with hopper 8 on frame 12, be tilting sieve 9 below the outlet of the lower end of hopper 8, and pulley 10 is installed below sieve 9, and pulley 10 is placed on guide rail 11, and guide rail 11 is fixed on crossbeam on frame 12; One side shaft of sieve 9 is connected to an end of pole 6, and pole 6 other end axles are connected on Rocker arm 5; The driving gear 7 of gearbox 1 inside and idle wheel 2 engagements, idle wheel 2 and driven gear 4 engagements, motor 3 drives driving gear 7, and driven gear 4 is coaxial with Rocker arm 5.

Operation principle:

Open motor, the drive driving gear rotates, be transmitted to idle wheel, driven gear also rotates, like this, the rocking arm coaxial with driven gear also rotates accordingly; circular motion is carried out along this axle in the outer end of rocking arm; because the pole axle is connected to the outer end; so; an end of drive pole moves in a circle along the axle of driven gear and rocking arm, thereby makes pole carry out stretching motion, pulls sieve to carry out left and right reciprocating swing motion; and the pulley on sieve slidably reciprocates on slide rail, reaches the sand on sieve is sieved to get.
