After material is entered in housing by charging aperture, fall on material stock groove, as conveyer belt hopper gradually transports material
Transport to discharge outlet.Pressure sensor is set by material stock trench bottom, the weight of material is received with real-time detection material stock trench bottom
Power pressure size is simultaneously sent to PLC, can be according to actual inlet amount, hopper loadings, conveyer belt transfer rate and material stock
Groove retaining amount sets pressure threshold scope in PLC, when the pressure that PLC receives pressure sensor transmission is big
When threshold range maximum, the servomotor of PLC control lowering or hoisting gear starts, and driving baffle plate to move downward makes charging
Mouth material is reduced by bore until control servomotor is stopped when receiving current pressure less than threshold value；When PLC controls
When the pressure of the pressure sensor transmission that device is received is less than threshold range minimum value, PLC controls watching for lowering or hoisting gear
Electric motor starting is taken, motion makes charging aperture material increase by bore upwards to drive baffle plate.
Preferably, be additionally provided with infrared sensor in the housing, the infrared sensor include infrared sensing transmitter and
Infrared sensing receiver, the infrared sensing transmitter is described infrared on case inside wall and positioned at the top of charging aperture
On conveyer belt and at the opening of hopper, the infrared sensor is communicated to connect sensing receiver with PLC.
Launch infrared ray by setting infrared sensing transmitter on case inside wall and above charging aperture, hopper is not
Under overload normal operation, infrared sensing receiver at one of hopper opening is with conveyer belt to red with described
During the position that outer sensing transmitter is adapted, receive infrared signal and be sent to PLC in real time, because conveyer belt is uniform
Operating, such PLC will receive infrared signal every the set time；When one of hopper is loaded in material stock groove
During amount overload, infrared sensing receiver at its opening is with conveyer belt to being adapted with the infrared sensing transmitter
During position, overburden portion material will cause to block to infrared sensing receiver, infrared signal is penetrated material, now
Infrared sensing receiver causes PLC not receive signal on the time interval point to receive infrared signal, then fixed
Justice is overloaded for hopper, and PLC control servomotor starts, and drives baffle plate to decline by lowering or hoisting gear, makes thing at charging aperture
Expect by bore reduce and reduce inlet amount.
Preferably, the lowering or hoisting gear is provided with protective housing.
Can effectively prevent lowering or hoisting gear from directly exposed being acted on by external force outside by setting containment vessel on lowering or hoisting gear
Damage.
Preferably, dividing plate is provided with the open slot, the dividing plate bottom is fixed on spring, the top of the dividing plate with
The bottom connection of baffle plate.
When baffle plate drives with lowering or hoisting gear to be declined, baffle plate produces downward active force to dividing plate, makes the bullet of dividing plate bottom
Spring is compressed, and dividing plate is moved downward, and baffle plate can block open slot, makes charging aperture inside and outer closures；When baffle plate is filled with lifting
When putting upward motion under driving, baffle plate produces upward active force to dividing plate, makes the spring recovery of dividing plate bottom or stretching, now
Dividing plate will directly block the open slot being exposed by dividing plate, outer so as to prevent material in charging aperture from being flowed to from open slot leak
Portion.
The utility model compared with prior art, has the following advantages and advantages：
1st, the utility model is used for the anti-overload bucket elevator of rice production, is set by lowering or hoisting gear band at charging aperture
The baffle plate of dynamic lifting, when material feeds excess, is declined, the bore that material passes through on charging aperture by lowering or hoisting gear controlling baffle plate
Diminish, inlet amount reduces；When inlet amount is too small, risen by lowering or hoisting gear controlling baffle plate, the mouth that material passes through on charging aperture
Footpath becomes big, inlet amount increase.Continuous control to elevator throat-fed amount is realized by this semiautomatic fashion, day is prevented
The factor such as delayed of regulation makes inlet amount excessive, elevator hopper overload, causes to the damage of equipment and production efficiency reduction
Problem；
2nd, the utility model is used for the anti-overload bucket elevator of rice production, by using pressure sensor or infrared biography
