Description

The vibration discharging silo that has the center discharge bucket

Technical field

the utility model relates to a kind of silo that has center discharge bucket and vibration drawing mechanism.

Background technology

bulk material such as circulatioies such as grain, mineral are bigger; Will degree of hoping for success higher to mechanization; It is global problem that material delivers from godown always, and for example directly through the following silo of 10m, the bottom can be made into cone for small-sized silo; Material can flow automatically fully and deliver from godown, and satisfies the mechanization production requirement.But because diameter is bigger, very high if the cone spatial altitude is made in the bottom for large-scale silo, cost is also very high simultaneously.With the silo is example, and grain is the basis to be processed have the flat of multiple exit with the common way of large-scale silo at present, and about 1/3rd grains of residue were put out cereal with spiral barn cleaning machine after the grain gravity flow was accomplished, and also has a small amount of residual grain after the machine of bringing down stocks is put out cereal and must lean on hand sweeping.Mineral can only use the less relatively storehouse of diameter type with silo, adopt awl bucket shape formula to deliver from godown.

The aspect ratio that the warehouse of awl bucket type takies warehouse is bigger, and plot ratio is low, and center of gravity is high.And adopt the warehouse of flat-bottom structure because the impassabitity gravity dumping can only adopt the spiral barn cleaning machine tool.This type of machinery not only cost is high, is embedded in when buying securities with all one's capital not only to be corroded easily below the material and damages, and needs manual work to keep an eye in the discharging process, very inconvenience.

Summary of the invention

The purpose of the utility model provides the large-scale silo that a kind of bulk material can full automaticity delivers from godown, be a kind ofly have the center discharge bucket, have the vibration drawing mechanism, can be low-cost, the vibration discharging silo that has the center discharge bucket of quickly discharging material.

The utility model purpose is achieved in that

have the vibration discharging silo of center discharge bucket, and its composition comprises: warehouse, have at the bottom of the storehouse of center gravity flow bucket and Cang Gai, and charging tray under install around described center gravity flow bucket centroclinal dip a group, described charging tray down connects soruce of vibration.

described vibration discharging silo that has the center discharge bucket, the described disc of charging tray down is fan-shaped or polygon, described charging tray bottom down has return spring.

described vibration discharging silo that has the center discharge bucket; Described soruce of vibration be vibration motor or with motor bonded assembly cam structure or pneumatic piston or hydraulic impulse piston, described soruce of vibration is installed in described down charging tray and is partial to center gravity flow bucket one side.

described vibration discharging silo that has the center discharge bucket; Pass through resistance material bridge joint earth between the disc of described charging tray down; Has the gap between described resistance material frame and the described disc; Described disc and horizontal surface angle of inclination 2-15 °, described return spring is leaf spring or extension spring or stage clip.

described vibration discharging silo that has the center discharge bucket connects through link slot between the described disc; And the angle of inclination 5-8 of described disc and horizontal surface °.

described vibration discharging silo that has the center discharge bucket, described resistance material frame both sides have the disc of spill and take ventilation slot in.

Beneficial effect:

1, the utility model have thoroughly solved the large-scale silo material problem that delivers from godown, and do not stay the dead angle after material delivers from godown, and no longer use labor cleaning's salvage stores.

if, the grain silo uses the utility model to deliver from godown, the grain machinery of having avoided using spiral barn cleaning machine to bring is broken, has kept the grain grade.

, since the utility model in vibrating disk simple in structure; There is not mechanical transmission structure; Soruce of vibration adopts external structure, can not influenced use owing to being embedded in the gap that produces corrosion or Transmission in the grain for a long time by clogged up with material as helical feed machinery.Use this product, reduced the interruption of service rate, improved service life, in the scale removal process, also no longer need supervision in the artificial storehouse.

, common large-scale warehouse need be provided with multiple exit in order to accelerate discharging, will set a plurality of machines road below, need to install a plurality of supporting machineries.When using the utility model, the mouth of putting out cereal has only one at center, has avoided trouble, has reduced the expense that is provided with.

, discharging speed are fast; The more common spiral barn cleaning machine speed that has of this product improves more than 5 times; When the grain silo uses the utility model; Because all vibrating disks of the utility model can be opened simultaneously or respectively, the speed of delivering from godown can increase substantially, avoided adopting in the traditional method mono-spiral barn cleaning machine because the operational throughput limitations affect delivers from godown speed issue.

. avoided the lower fault of construction of plot ratio of taper warehouse; Through mode of vibration under the very little situation of the gradient; Can successfully realize self-emptying through vibration, not only effectively reduce the height and the height of gravitational center of warehouse, can also hang down foundation cost significantly; The output section cost reduces by 70%, has broken through the traditional habit that can only adopt wide-angle awl bucket could realize self-emptying in the traditional concept.

The vibration drawing mechanism of this product comprises fan-shaped or the polygon baiting dish, by being bordered between the disc, forms the tapping channel of a rule, the economy index requirement that requires with the different-diameter that adapts to silo.Each down is provided with return spring in the disc bottom of charging tray,, load lighter the time near finishing in the gravity flow discharging, lifts disc on the spring, touches travel switch, thereby makes the motor unlatching of soruce of vibration, begins to vibrate discharging, also can manually boot the vibration discharging.When described soruce of vibration is installed in described vibration drawing mechanism and is partial to center gravity flow bucket one side, more save power of motor, same power effect is also better, and the lifting of disc has reduced the energy of attrition significantly.

. can pass through resistance material bridge joint earth between the disc of the following charging tray of the utility model; The resistance material frame both sides that border on have the disc of spill and take groove in; Have the gap between described resistance material frame and the described disc, after being convenient to the end and stretching into wherein, the shake of disc is unfettered; The angle of inclination of disc all can meet the demands at 2-15 °, angle of inclination 5-8 ° better effects if.

. the disc of the spill of the utility model is taken ventilation slot can be used to the to ventilate vent passages of warehouse in, with reducing grain moisture content or temperature, perhaps imports hot blast and improves little temperature and improving discharging environment that freezes coal dust under the state.And it is farther that the rigidity that link slot has improved disc makes that conduct vibrations gets, the discharging better effects if.

. the utility model has been broken away from the conventional art or has been adopted the awl end; Awkward awkward selection of the spiral barn cleaning machine that perhaps purchase price is expensive provides the new departure that only utilizes low-down cost just can start the quickly discharging structure of various material bins.Broken the bottleneck of the ability that delivers from godown, solved a traditional difficult problem less than the load-transfer device ability.Assert worldwide still do not have this series products and report through examination and expert, receive country and industry leader's great attention.This product will bring the great revolution of storage industry.
