The device consists of an activating device, a rubber sealing ring, a plate spring seat, a plate-type spring, a fixed rack, a vibration motor and a discharging hopper part. The device has the advantages that the device has greater amplitude, greater vibration force and stronger arch breaking capability, the plate spring has higher rigidity, can bear great load and can be applicable to the material storehouse with large capacity, the spring has relatively long service life, and the device can run more reliably in whole.
Description
Technical field
The utility model relates to activation device for discharging at the bottom of a kind of novel storehouse that is used for graininess, granular material vibration discharging.
Background technology
Be stored in the material of material in the storehouse and since between pressure and the material particles adhere to and the effect of cohesiveness causes arching phenomenon easily, make material stop up, influence ordinary production.At present, adopt usually that the vibration unloader becomes the forced vibration discharging to traditional gravity from the rolling material at the bottom of the storehouse, the flowing power of storehouse inner bottom part material strengthened, thus make material evenly, discharge continuously.The vibration unloader is made up of two independent parts up and down at the bottom of the storehouse, and top is divided into fixed mount, is fixed on the bottom of feed bin, and the bottom is divided into the vibration activated part, involving vibrations motor, activator and hopper etc.The vibration activated part is suspended on the fixed mount by suspension rod, suspension rod has certain stroke, when equipment operation, produce power by vibrating motor and drive activator and hopper vibration, activator is radioactivation with vibratory force and passes material in the storehouse, destroys the knot doming effect that material may occur, material flows into hopper and carries out discharging under vibratory force and gravity combined action, and when equipment stopped, activator stopped up material, and discharging stops thereupon.
Its Oscillation Amplitude of vibration unloader of this kind form has only 3-5mm, and this is determined that by its version the suspension rod both sides are embedded with the bolt mounting holes of steel, is filling special elastomeric material between suspension rod body and the mounting hole.When vibrating motor moved, elastomeric material shrinks under the action of gravity of power that vibrating motor produces and material upheld, and forms vibration.This shows that possible maximal dilation amount is determining the amplitude of this unloader to bolt hole at the suspension rod two ends just, but it is very limited again, this vibration unloader is applicable to food-processing industry, as the activation discharging of storage bins such as flour or cereal.But in cement industry, because the cement raw material granularity is not of uniform size, reasons such as cement life or grog water ratio are higher, the easier arch camber of material, therefore, the amplitude that is used for the dynamics of its vibration of vibration device for discharging at the bottom of the storehouse of cement storage bin and vibrational all should be bigger, could guarantee normal discharging like this.
The utility model content
The purpose of this utility model provides and activates device for discharging at the bottom of a kind of leaf spring supports novel storehouse.
A kind of leaf spring activates device for discharging at the bottom of supporting novel storehouse, form by activator, rubber seal, spring block, flat spring, fixed mount, vibrating motor and hopper, activator, vibrating motor, hopper separate with feed bin, be supported on by flat spring on the inspection platform of feed bin, rubber seal is fixed on the outer wall of feed bin by fixed mount, and flat spring is installed on the bunker platform by spring block.
4 cover scroll wheels are set in the described spring block, and flat spring is floated above scroll wheel.
Described flat spring is arc leaf spring, and two cover symmetries.
The parameter that the utility model mates vibrating motor and leaf spring according to the weight of volume, material characteristic and the hopper of feed bin is to obtain bigger vibration intensity and amplitude.After tested, the device peak swing behind the remodeling can reach more than the 25mm, and oscillatory torque can reach 25kN, and its broken arch ability has had very big raising, can satisfy the requirement of the normal discharging of cement storage bin.
The advantage of this covering device is:
1. Zhuan Zhi Oscillation Amplitude and vibration intensity are bigger, and its broken arch ability is stronger;
2. the rigidity of leaf spring is higher, can bear very big load, is applicable to high-capacity feed bin;
The service life of spring longer relatively, the device overall operation reliability higher.

Wherein: 1 activator, 2 rubber seal, 3 spring blocks, 4 flat springs, 5 fixed mounts, 6 vibrating motors, 7 hoppers, 8 leaf springs, 9 scroll wheels, 10 feed bins
The specific embodiment
As shown in Figure 1, the utility model vibration activation feeder is by activator 1, rubber seal 2, spring block 3, flat spring 4, fixed mount 5, vibrating motor 6 and hopper 7 are formed, wherein activator 1, vibration such as vibrating motor 6 and hopper 7 activated part is formed one, the two cover template springs of being installed by symmetry 4 are supported on the platform of cement storage bin (10), flat spring 4 is arc, two ends are unfixing, float on the scroll wheel of spring block 3, the vibration activated part is separated with feed bin (10), the centre is flexible coupling for contractile, outside with rubber seal 2 sealings, be fixed in feed bin (10) outer wall by fixed mount 5, in case flying dust splashes in the equipment running process.Produce vibratory force clocklike during vibrating motor 6 operation, the flat spring 4 that causes support is modification clocklike, and the vibration activated part that drives unloader is clocklike vibrated.The activator 1 that stretches in the feed bin passes to material in the storehouse with vibratory force, make material fall into hopper 7 from the gap between activator 1 and the bin wall equably along the groove of activator 1, when equipment stopped, activator 1 stopped up material, discharging stops thereupon, thereby realizes the purpose of controlled discharging.
Shown in Fig. 2 a and Fig. 2 b, the leaf spring that this programme uses is arc, and top is fixed with vibration unloader pedestal, and insert respectively in the spring block 3 that is fixed on the bunker platform at the two ends of leaf spring.Shown in Fig. 3 a and Fig. 3 b, 4 scroll wheels 9 are set in the spring block 3, flat spring 4 is placed on the scroll wheel 9.When the pressure that flat spring 4 is subjected to increased, flat spring 4 arch roof stayed, and stretched to two ends simultaneously, produced antagonistic force by distortion, and the pressure that bears with it reaches balance; When pressure reduced, flat spring 4 shrank thereupon, and so circulation forms vibration processes.Because scroll wheel 9 rotates flexibly, makes flat spring 4 not interrupted.
