Description
Technical field
The utility model is related to grain depot insect prevention equipment technical fields, stifling more particularly to a kind of multi-stage circulating
System.
Background technology
China human mortality is numerous, and the demand to grain is big, ensures the stabilization of staple food supply, is social fast-developing foundation.
It is flat warehouse mostly used in existing grain storage, simple in structure, low cost is the important equipment of grain storage.
And grain is in storing process, and due to there are pest, needing periodically to be killed to it in grain, the foodstuff pest of the prior art
Killing means mostly use the mode of recirculation fumigation, but since space is big, and grain amount of storage is more, to make an overall screening, and need to expend big
Medicament is measured, simultaneously as grain accumulation is more, can be fully cleaned, need to stir grain position, workload is huge.
Utility model content
The purpose of this utility model is that：In order to solve the grain storage vermin exterminating apparatus amount of consumption of drugs and workload of the prior art
Greatly, incomplete problem is fumigated, the utility model provides a kind of multi-stage circulating fumigation system.
The utility model specifically uses following technical scheme to achieve the goals above：
A kind of multi-stage circulating fumigation system, including braced frame, level-one fumigate mechanism and two level fumigates mechanism, the level-one
Stifling mechanism and two level are fumigated mechanism and are sequentially fixed in braced frame from top to bottom；
It includes stifling cylinder, auger piece, rotation axis, driving motor and for being interrupted that the level-one, which fumigates mechanism,
For the chemical spraying mechanism of medicine, the stifling cylinder is fixed in braced frame, and the central shaft in stifling cylinder is arranged in the rotation axis
On line, on the rotating shaft, the driving motor is arranged in the top of stifling cylinder, the driving electricity for the auger piece winding
The output end of machine is fixed on the side wall of stifling cylinder with rotation axis connection, the chemical spraying mechanism, and the chemical spraying mechanism passes through pipeline
It is connected to stifling cylinder；
It includes PVC pipeline under trapped orbit, sliding shoe, S type films, the first air blower, the second drum that the two level, which fumigates mechanism,
Wind turbine, feeding port, stifling hole, material keep in lattice, and the trapped orbit is arranged under the underface of braced frame, the S types film
PVC pipeline is mounted on by sliding shoe on trapped orbit, first air blower and the second air blower respectively with PVC under S type films
Company's section connection of pipeline, the feeding port are opened in the end of PVC pipeline under S type films, and the stifling hole is distributed under S type films
The upper surface of PVC pipeline, the material are kept in lattice and are arranged at the middle part of braced frame.
Preferably, the chemical spraying mechanism includes seal cavity, crankshaft, mandril, piston, ball sealer, conversion chamber, connects
It threads a pipe, dismantle medicine bottle, the seal cavity is mounted on by holder on the side wall of stifling cylinder, and the seal cavity passes through defeated
Go out pipeline to be connected to stifling cylinder, the piston is hinged by the end of mandril and crankshaft, and the piston is just gone back above
It is provided with the triggering end for pushing ball sealer, the triggering end is located at the underface of ball sealer, and the ball sealer, which is placed on, to be turned
Intracavitary is changed, the conversion chamber connection is connected to by connecting pipe with conversion chamber in the top of seal cavity, the dismounting medicine bottle.
Preferably, the material, which keeps in perforation on the inner panel of lattice, is evenly equipped with air hole.
It is made preferably, the braced frame is integrally machined using 6 line aluminium alloy proximate matters.
The beneficial effects of the utility model are as follows：
1. the foodstuff pest of the prior art kills the mode that means mostly use recirculation fumigation, but since space is big, grain is deposited
Reserves are more, to make an overall screening, and need to expend a large amount of medicaments, simultaneously as grain accumulation is more, can be fully cleaned, need
Stir grain position, workload is huge, this is resulted in during actually stifling, fumigated caused by stirring difficulty less than
Position, often the grain on only surface is fumigated, and expected fumigating effect is not achieved.For this problem, the present apparatus devises multistage
Stifling mechanism, using different direction, different modes are fumigated, and so that grain is fumigated by comprehensive, more thorough, are greatly improved
Fumigating effect and utilization ratio of drug.When the present apparatus works, grain is transported to level-one first and fumigates stifling cylinder within the organization
It is interior, while starting the control switch of chemical spraying mechanism, to the intermittent supply fumigating medicine of stifling cylinder, meanwhile, start driving motor,
Auger piece starts to stir, and so that stifling grain and drug is more fully contacted, relative to traditional open a wide range of spray
It spills, since the present apparatus is a cut-off medicine, can more efficiently utilize drug, improve and fumigate efficiency；When level-one fumigates mechanism operation
After the completion, grain is transported to two level to fumigate in the temporary lattice of material within the organization, adjusts the position of sliding shoe, makes PVC under S type films
Pipeline, which is moved to, to be needed below stifling grain, is added from feeding port and is fumigated medicinal powder, starts the first air blower and the second air blast
Machine, medicinal powder move along PVC pipeline under S type films under the drive of air stream, when moving to stifling hole, just go out S types upwards
PVC pipeline under film, due to the effect of pressure-air, stifling medicinal powder still has the potential energy moved upwards, to temporary across material
It deposits lattice to enter in grain heap, realizes that the two level of grain is stifling, the manual operation that whole process needs is seldom, substantially increases grain
The stifling efficiency of food.
2. in order to more efficiently utilize fumigating medicine, the present apparatus to use a design for cut-off medicine.When the present apparatus works,
Start Miniature drive motor, drive crankshaft rotation, to drive piston up-down, piston upwards are to close to conversion
When chamber, triggering end pushes into the underface of ball sealer, it is risen calmly upwards, depressurization state, when piston is downward, generation
The drug dismantled in medicine bottle is then attracted in seal cavity by negative pressure, at this point, piston continues to move downward, when the surface of piston is transported
When moving the horizontal position less than output pipe, drug will enter in fumigation tube body along pipeline, repeat above-mentioned be moved through
Journey just can play the role of automatic ration conveying drug, realize a cut-off medicine, improve the utilization ratio of drug.
It, can be by drug corruption when using although common brandreth low cost 3. the present apparatus needs to bear larger pressure
Erosion leads to the reduction of braced frame stability, and there are security risks.For this problem, the present apparatus further to braced frame into
Optimization is gone, using structural strength height, corrosion resistant 6 line aluminium alloy shape extrusion is made, to improve braced frame
Stability, reduce the weight of the present apparatus, to reduce the influence to braced frame, improve the present apparatus use the longevity
Life.
