Description
Technical field
The invention belongs to waste Removal Technology field, it is related to a kind of pig house intelligence step-by-step movement and scrapes excrement system, more particularly to
A kind of pig house intelligence step-by-step movement dung scraping device.
Background technique
China is pig-breeding big country, and feeding live pig amount accounts for the half or so of global total amount, in recent years, China's pig-breeding
Industry scale level is continuously improved, and provides solid guarantee for food supply, but a large amount of cultivation wastes are not effectively addressed
And utilization, become a great problem of Countryside Environment Rectification, also constrains the sustainable development of pig-breeding industry itself.
Cleaning up excrement is one of the important link of piggery waste comprehensive treatment, is that excrement, urine and sewage in pig house etc. is dirty
Dye object is collected and clears up to pig house, convenient for unified centralized processing and utilizes.Currently, the cleaning up excrement technique of large-scale pig farm
Mainly have bubble excrement, water to rush excrement, mechanical 3 kinds of cleaning up excrement: 1. water rushes excrement, is carried out to the excrement in dropping pit clear using high pressure water flow
Reason, problem is that water consumption is big, at the same flushing water mixed with excrement after also become sewage, and then greatly increase at later period sewage
Reason amount and processing cost；2. the wastes mixture such as bubble excrement, i.e. excrement, urine, sewage is long-term stored in dropping pit and periodically arranges
It puts, by the way that the dropping pit gradient is arranged, is discharged using waste self weight, on the one hand problem is that solid-state excrement long time sedimentation simultaneously glues
Knot is in dropping pit bottom surface, and if things go on like this, cleaning difficulty is big, cleaning work is dangerous, on the other hand, the waste being largely accumulated in dropping pit
When disposable discharge, due to the agitation of waste, the pernicious gases such as a large amount of ammonias of meeting abrupt release, methane, hydrogen sulfide are seriously endangered
Pig and keeper's life and health；3. mechanical cleaning up excrement generally uses manure scraper plate, using machine power to the excrement in dropping pit into
Row is collected and cleaning.
What current China pig farm generallyd use mechanical cleaning up excrement has two kinds of cable type, step-by-step movement, wherein cable type generally uses
The problem of 2 dropping pits are connected to form closed loop by the soft transmission material such as flat rope, wirerope, iron chains, which is to make for a long time
Dilatation can occur with the rope of rear various materials, and then slurry scraper traffic direction is caused to deviate, cause operation troubles；Step
It is to be applied to 1 dropping pit using hard transmission materials such as channel steels, by reciprocating power mechanism, before realizing slurry scraper into formula
Into, the operation that retreats, the mechanical stability for scraping excrement system is effectively increased.
The step-by-step movement slurry scraper dynamical system of current pig house mostly uses greatly hydraulic-driven or curved arm rod to drive, and still deposits
In following deficiency: 1. hydraulic-driven speed is slower, needs to regularly replace hydraulic oil, and there are oil sealing breakage oil leaks for long-play
Risk, moreover, fluid power system control mode is complicated, connection line is more, causes failure risk larger, operation stability
Lower, maintenance workload is big；Although transmission efficiency is lower, longtime running mechanism wear 2. curved arm rod power mechanism is simple
More serious, service life is lower；3. slurry scraper operational process lack of wisdom controls, for example encounters that excrement amount is excessive, hard foreign matter
Be caught in, the abnormal conditions such as system structure damage when, drive rod pushes away the abnormal increase of (drawings) force value, but machine can not be automatically stopped, into
And continuous service generates mortal injury to manure scraper plate, dropping pit etc., restores and maintenance and repair difficulty is big, at high cost.
