Operating principle of the present invention is like Fig. 1, shown in 2, and wind enters air motor 2 from airduct 4, drives the work of air motor 2; The handle 1 that the people is holding up inserts charging aperture 7 in the material that mixes, and adjusted valve 3 carries out the regulation and control of wind speed size then, and air motor 2 drives the rotation of screw rod 6; Screw rod 6 drives the stirring of stirring-head 10, can stir material uniformly like this, and material gets into from charging aperture 7; The rotation of screw rod 6 drives the rising of material, comes out from discharging opening 5 then.
Brief introduction of the present invention:
One, the artificial material-uploading style of former whitewashing
(1), by manual work at dust and sand stock ground tide spice, cement, river sand and aggregate chips be the end and turn over three times it is mixed clearly.Be transported to the pulp shooting machine place by mine car, again by manual work from shoveling out material loading in the mine car to pulp shooting machine, whitewash.
The whitewashing program: base plate turns material → dress mine car → unloading miner's truck → material loading to pulp shooting machine
(2), the problem and shortage of former artificial material-uploading style existence
1. worker's labour intensity is big, and physical demands is big, and operating efficiency is low.
2. artificial material loading is prone to the dust of kicking up, and is bigger to the site work environment influence.
3. the user of service is many.
4. artificial material loading speed is inhomogeneous, and whitewashing resilience material is big.
Two, the research of pneumatic feeding device and application
To the problem and shortage that the artificial material-uploading style of whitewashing exists, minimizing personnel take, and alleviates worker worker's labour intensity, improves operating efficiency, improves site work environment, reduces the generation of whitewashing resilience material, and pneumatic feeding device has been made in research.
(1), the basic condition of pneumatic feeding device
This device volume is less, and light being prone to moves, and highly is 1.2m; Weight has only 20Kg, adopts 8 cun Plastic Steel Pipe processing and fabricatings of light-duty heavy wall, adopts the band iron Spin welding to be connected into spiral rotation material loading bar; Be installed in 8 cun Plastic Steel Pipe; As power motor, drive spiral rotation material loading bar through wind turbine, the sand-lime in the mine car is carried unloaded to the pulp shooting machine feed inlet.Regulate the air quantity size with what of control discharging, add material evenly, rapid speed.Through field measurement, artificial material loading, per car need 20 fens clock times, adopt pneumatic material loading, and per car only needs the time about 15 clocks, and per car is practiced thrift 5 clocks, calculate with per tour 18 cars of whitewashing, and per tour is practiced thrift the whitewashing time and just reached 1.5 hours.Simultaneously, to the kicking up of dust, and we have also added the combined dust-eliminating cover of transparent mode above pulp shooting machine, purified site work environment, have reduced the harm of dust to human body when adopting pneumatic feeding device not only to reduce artificial material loading.
(2), the use of pneumatic feeding device
The pneumatic feeding device of whitewashing is put in the mine car of charging, inserted wind regime, holding up handle 1 by personnel, start control valve 3, the dust and sand material in the mine car is carried unloaded to discharging opening 5, adjusted valve 3 is regulated the wind speed size, with the speed of control material loading what and material loading.
Three, invention effect: after adopting pneumatic feeding device, obtained better economic, social benefit:
1, this innovation belongs to on-the-spot practical invention, has alleviated worker's labour intensity greatly, has practiced thrift the great amount of manpower work; Per tour in the past needs 10 gunite works that the worker could accomplish; Existing needs 7 workers just can easily accomplish, and has improved operating efficiency, has practiced thrift manpower; Per tour reduces by 3 workers, year practice thrift the work expenditure reach 90,000 surplus yuan.
2, through field measurement, artificial material loading, per car needs 20 fens clock times, adopts pneumatic material loading, and per car only needs the time about 15 clocks, and per car is practiced thrift 5 clocks, calculates with per tour 18 cars of whitewashing, and per tour is practiced thrift the whitewashing time and is just reached 1.5 hours.
To the kicking up of dust, purified site work environment when 3, adopting pneumatic feeding device to reduce artificial material loading, reduced the harm of dust human body.
4, through field measurement, originally artificial material loading whitewashing needs 10 people, whitewashing about 18 cars, change pneumatic material loading into after, only need 7 people just can accomplish spray operation, and whitewash about 22 cars, improved operating efficiency greatly.
