Description

Two-section speed-regulating cantilevel quantitative feeder

A kind of two section speed governing cantilevered constant feeder belongs to the metering outfit technical field.

In the prior art, existing quantitative and batcher have two kinds of structures, and a kind of is the speed governing type constant feeder, its structure mostly is single mount roll shape formula greatly, and measuring accuracy is poor, complex structure, volume is big, and the cost height is difficult to realize to the demanding processing range of proportioning accuracy.Another kind is the constant speed type constant feeder, mostly is cantilevered greatly, though precision is higher, its structure is a cantilevered, fulcrum only, and it drives driving section and is mounted on the cantilevered batcher fuselage, therefore, the influence that mechanical vibration bring makes work not steady; Can not take directly to press the storehouse formula to draw material, and must rely on electro-vibrating feeder or other pattern batcher to carry out pre-feed, have a strong impact on workers ' health and environmental pollution, directly influence measuring accuracy and stable working.Particularly work as material in the low discharge scope below 150 kilograms/hour, the work linearity of pre-batcher is poor especially, so its measuring accuracy and stability are poorer in the low discharge scope.

The purpose of this utility model is to overcome above-mentioned weak point, thus provide a kind of simple in structure, compact, cost is low, metering is correct, can protect two section speed governing cantilevered constant feeders of workers ' health.

Main solution of the present utility model is achieved in that it mainly is made up of material feeding section, weighing section, pedestal, sensor, conveying belt, and conveying belt connects the material feeding section, the weighing section is installed on the pedestal, between weighing section below and pedestal sensor is housed.

The material feeding section is fixed on the pedestal; buncher, reductor, material feeding section top are housed on the pedestal are equipped with that fixed frame, frame head are equipped with drive roll, middle lower portion is equipped with swelling device, frame below dress carrying roller, weighing section is fixed on the pedestal; the gravity pressure frame is equipped with at the weighing section middle part; head end is equipped with balance bob, and the scale frame is contained on the resetting-mechanism, and scale frame afterbody is equipped with driven cylinder; the adjustment bolt is equipped with in driven cylinder both sides; clearer is equipped with in the bottom, and carrying roller is equipped with on scale frame top, and protective device is housed.

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

The utility model mainly is made up of material feeding section 1, weighing section 2, pedestal 3, conveying belt 11, sensor 14.Conveying belt 11 connects material feeding sections 1, weighing section 2 is installed on the pedestal 3, below weighing section and 3 of pedestals sensor 11 is housed, be shaped as rectangle.One section of fuselage is that speed governing batcher, bottom are fixed on the pedestal 3 for material feeding section 1, material feeding section 1.Buncher 4 and reductor 5 are housed on the pedestal of material feeding section 1 end.The top of material feeding section 1, fixed frame 6 is housed, at frame 6 heads drive roll 7 is housed, middle lower portion is equipped with conveying belt swelling device 8, frame 6 tops are uniform is equipped with several groups of bearing material carrying rollers 9, frame 6 afterbodys top is equipped with one group and is become into carrying roller 21 on the center line of resetting-mechanism 13, the carrying roller 22 that becomes out is equipped with in the below, during work, buncher 4 drives reductor 5, by chain 10 transmissions, make drive roll 7 runnings, drive annular jointless conveyer belt 11 motions by drive roll 7.The feed opening of hopper 20 is over against above several groups of bearing material carrying rollers 9 on the material feeding section 1.When conveying belt moved, material was just directly pulled out from feed bin 20, and without any need for pre-batcher.When material process on conveying belt becomes into carrying roller 21, promptly enter weighing section 2 by fixed material feeding section 1, carry out material metering or dosing, and after conveying belt 11 turns to through driven cylinder 15, when the return passage in transit becomes out carrying roller 22, just leave weighing section 2, return material feeding section 1, to guarantee independence, stability and the degree of accuracy of cantilevered weighing section.

At the other end of fuselage, promptly be cantilevered weighing section 2, the weighing section bottom is fixed on the pedestal, scale frame 12 is housed on the weighing section 2 is installed on the resetting-mechanism 13, cantilever stretches out, and at scale frame 12 afterbodys driven cylinder is housed, make cycloconveyor belt make divertical motion, and will shed through the material of metering.In driven cylinder 15 both sides; belt deflection is housed adjusts bolt 16; driven cylinder 15 bottoms are equipped with material clearer 26 and are prevented that material is stained with and be bonded on the conveying belt 11; be evenly equipped with several groups little carrying rollers 17 on scale frame 12 tops; to prevent that material from making conveying belt 11 sagging, in addition, claiming on the frame 12 safety guard 27 to be housed; quit work and transportation in, weighing section 2 is in order to avoid damage resetting-mechanism 13 and sensor 14.At the middle part of weighing section 2 gravity pressure frame 18 is housed, the weight of material is passed on the load sensor.Owing to do not have drive unit on the weighing section 2, so steadily reliable, and the bounce-back principle by array spring leaf 25 on the resetting-mechanism 13 has guaranteed the linearity of weighing section 2 and repeated.Resetting-mechanism 13 adopts two groups of reeds 25 intersection composition reed support mutually, be arranged in the scale frame both sides of weighing section 2 respectively, its movable block 23 links with scale frame 12, its fixed block 24 is connected with pedestal 3, for making weighing section 2 firm being pressed on the sensor 14, the balance bob 19 of adjustable weight is housed at the head end of weighing section 2.Sensor 14 and buncher 4 interconnect with electric controller 28.

When dosing, the stressed electric signal that sends of load sensor on the batcher, tachogenerator sends the speed signal, sets at electric controller under the control of feeding coal, can realize dosing (i.e. batching) accurately, precision≤0.5%.Batcher can with the mutual combined ingredient of the electric controller of various types system.

Compared with the prior art the utility model has the following advantages: 1, simple in structure, compact, make easy to use; 2, stable working, precision height; 3, cost is low, metering is correct; 4, its all size can satisfy 0.05t/h---and the dosing of 100t/h scope is specially adapted to building materials, the automatic proportioning in the fields such as chemical industry, metallurgy, grain.
